Medical Record Review (medical + record_review)
Kinds of Medical Record Review Selected AbstractsElectronic Medical Record Review as a Surrogate to Telephone Follow-up to Establish Outcome for Diagnostic Research Studies in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 11 2005Jeffrey A. Kline MD Abstract Background: Follow-up for diagnostic research studies might be facilitated if medical record review (MRR) could be used instead of telephone calls. Objectives: The authors hypothesized that MRR would yield similar accuracy to telephone follow-up. Methods: This was a secondary analysis of 2,178 initially disease-free patients who were followed after enrollment in a diagnostic study of either acute coronary syndrome (45 days) or pulmonary embolism (90 days) conducted in an urban teaching emergency department (ED). Disease status (positive or negative) was defined explicitly. Using structured data forms, trained researchers performed MRR using a comprehensive electronic database, and formulated an opinion about disease status. Trained researchers, blinded to the MRR, then dialed telephone numbers, asked questions from a script, and categorized disease status. The criterion standard was adjudication by consensus of two of three physicians who independently determined disease status based on explicit criteria and access to all follow-up data. Results: Adjudicators found that 13 of 2,178 patients developed disease during follow-up; all 13 true positives occurred among the 2,054 (94.3%) of patients who acknowledged intent to return to the study hospital. Telephone follow-up was successful in 81% of patients, and found all 13 true positives (sensitivity 100%) but with three additional false-positive cases. MRR disclosed 12 of 13 cases of disease (sensitivity 92%) with no false-positive cases. Further review of the one false-negative case from MRR revealed that it occurred after the prescribed time limit for follow-up. Conclusions: Under limited circumstances, accurate clinical follow-up for diagnostic studies conducted in the ED can be obtained by medical record review. [source] Adherence to Pressure Ulcer Prevention Guidelines: Implications for Nursing Home QualityJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2003Debra Saliba MD OBJECTIVES: This study aims to assess overall nursing home (NH) implementation of pressure ulcer (PU) prevention guidelines and variation in implementation rates among a geographically diverse sample of NHs. DESIGN: Review of NH medical records. SETTING: A geographically diverse sample of 35 Veterans Health Administration NHs. PARTICIPANTS: A nested random sample of 834 residents free of PU on admission. MEASUREMENTS: Adherence to explicit quality review criteria based on the Agency for Healthcare Research and Quality Practice Guidelines for PU prevention was measured. Medical record review was used to determine overall and facility-specific adherence rates for 15 PU guideline recommendations and for a subset of six key recommendations judged as most critical. RESULTS: Six thousand two hundred eighty-three instances were identified in which one of the 15 guideline recommendations was applicable to a study patient based on a specific indication or resident characteristic in the medical record. NH clinicians adhered to the appropriate recommendation in 41% of these instances. For the six key recommendations, clinicians adhered in 50% of instances. NHs varied significantly in adherence to indicated guideline recommendations, ranging from 29% to 51% overall adherence across all 15 recommendations (P < .001) and from 24% to 75% across the six key recommendations (P < .001). Adherence rates for specific indications also varied, ranging from 94% (skin inspection) to 1% (education of residents or families). Standardized assessment of PU risk was identified as one of the most important and measurable recommendations. Clinicians performed this assessment in only 61% of patients for whom it was indicated. CONCLUSIONS: NHs' overall adherence to PU prevention guidelines is relatively low and is characterized by large variations between homes in adherence to many recommendations. The low level of adherence and high level of variation to many best-care practices for PU prevention indicate a continued need for quality improvement, particularly for some guidelines. [source] Age-Specific Differences in Women with Implantable Cardioverter Defibrillators: An International Multi Center StudyPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 12 2008LAUREN D. VAZQUEZ M.S. Background: Common psychological adjustment difficulties have been identified for groups of implantable cardioverter defibrillator patients, such as those who are young (<50 years old), have been shocked, and are female. Specific aspects and concerns, such as fears of death or shock and body image concerns, that increase the chance of distress, have not been examined in different aged female implantable cardioverter defibrillator (ICD) recipients. The aim of the study was to investigate these areas of adjustment across three age groups of women from multiple centers. Methods: Eighty-eight female ICD patients were recruited at three medical centers: Shands Hospital at the University of Florida, Brigham and Women's Hospital in Boston, and Royal North Shore Hospital in Sydney, Australia. Women completed individual psychological assessment batteries, measuring the constructs of shock anxiety, death anxiety, and body image concerns. Medical record review was conducted for all patients regarding cardiac illnesses and ICD-specific data. Results: Multivariate and univariate analyses of variance revealed that younger women reported significantly higher rates of shock and death anxiety (Pillai's F = 3.053, P = 0.018, ,2p= 0.067) and significantly greater body image concerns (Pillai's F = 4.198, P = 0.018, ,2p= 0.090) than middle- and older-aged women. Conclusions: Women under the age of 50 appear to be at greater risk for the development of psychosocial distress associated with shock anxiety, death anxiety, and body image. Clinical-based strategies and interventions targeting these types of adjustment difficulties in younger women may allow for improved psychosocial and quality of life outcomes. [source] Early Surgical Morbidity and Mortality in Adults with Congenital Heart Disease: The University of Michigan ExperienceCONGENITAL HEART DISEASE, Issue 2 2008Ginnie L. Abarbanell MD ABSTRACT Objectives., To review early surgical outcomes in a contemporary series of adults with congenital heart disease (CHD) undergoing cardiac operations at the University of Michigan, and to investigate possible preoperative and intraoperative risk factors for morbidity and mortality. Methods., A retrospective medical record review was performed for all patients ,18 years of age who underwent open heart operations by a pediatric cardiothoracic surgeon at the University of Michigan Congenital Heart Center between January 1, 1998 and December 31, 2004. Records from a cohort of pediatric patients ages 1,17 years were matched to a subset of the adult patients by surgical procedure and date of operation. Results., In total, 243 cardiac surgical operations were performed in 234 adult patients with CHD. Overall mortality was 4.7% (11/234). The incidence of major postoperative complications was 10% (23/234) with a 19% (45/23) minor complication rate. The most common postoperative complication was atrial arrhythmias in 10.8% (25/234). The presence of preoperative lung or liver disease, prolonged cardiopulmonary bypass and aortic cross clamp times, and postoperative elevated inotropic score and serum lactates were significant predictors of mortality in adults. There was no difference between the adult and pediatric cohorts in terms of mortality and morbidity. Conclusions., The postoperative course in adults following surgery for CHD is generally uncomplicated and early survival should be expected. Certain risk factors for increased mortality in this patient population may include preoperative presence of chronic lung or liver dysfunction, prolonged cardiopulmonary bypass and aortic cross-clamp times, and postoperative elevated inotropic score and serum lactate levels. [source] Detecting Adverse Events in Dermatologic SurgeryDERMATOLOGIC SURGERY, Issue 1 2010DANIEL PINNEY BS BACKGROUND Despite increasing awareness of and public attention to patient safety, little is documented about how adverse events (AEs) can or should be monitored in dermatologic surgery. Data to address this shortcoming are needed, although well-defined methodologies have yet to be implemented. OBJECTIVE To summarize current strategies in detecting adverse outcomes of dermatologic surgical procedures. MATERIALS AND METHODS A Medline literature search was conducted using the terms "adverse event,""detection,""reporting,""monitoring," and "surgery." Articles selected addressed the efficacy of one or more AE reporting techniques in surgical patients. RESULTS Prospective and retrospective reporting methods were identified, with morbidity and mortality conference being the most commonly used method of AE reporting. Retrospective medical record review, the retrospective trigger tool approach, and an anonymous electronic reporting system were more sensitive approaches. The Surgical Quality Improvement Program, a program that has successfully translated AE data into lower postoperative morbidity and mortality, was analyzed. CONCLUSIONS Although generally considered safe, dermatologic surgery has no current standard for AE reporting. Standard definitions and high-quality data regarding AEs" currently limit this analysis. Pilot studies are needed to develop feasible measures, with the goal of increasing the sensitivity of AE detection and ultimately improving patient outcomes. The Center for Dermatology Research is supported by an unrestricted educational grant from Galderma Laboratories. [source] Foot abnormalities in Canadian Aboriginal adolescents with Type 2 diabetesDIABETIC MEDICINE, Issue 7 2007J. Chuback Abstract Aims To determine the profile of foot abnormalities in Canadian Aboriginal adolescents with Type 2 diabetes and the risk factors associated with these abnormalities. Methods Aboriginal adolescents with Type 2 diabetes underwent an interview, medical record review and foot examination in a tertiary care, paediatric hospital diabetes clinic and two geographically remote outreach clinics. The notes of 110 subjects were reviewed [mean age 15 ± 3 years; mean duration of diabetes, 30 ± 20 months; 71 (66%) female and 39 (34%) male] and 77 (70%) of the subjects were examined. Results Foot abnormalities were identified by either interview or notes review, and included poor toenail condition in 85 (77%), paronychia in 29 (26%), ingrowing toenails in 16 (15%) and neuropathic symptoms in 13 (12%) subjects. Foot abnormalities were identified by examination in many subjects, including poor toenail condition in 38 (49%), calluses in 34 (44%) and paronychia in 13 (17%) subjects. Eighteen (24%) of 75 subjects did not have running water in the home. Factors that significantly increased the presence of foot abnormalities included: foot care provided by a person other than self; absence of running water in the home; decreased frequency of bathing; and decreased frequency of nail clipping. A greater percentage of subjects living on a reservation or rural community had specialized consultations for retinal examination, footwear, or both than of those living in an urban or unknown residence. Conclusions A high prevalence of foot abnormalities was noted in Aboriginal adolescents with Type 2 diabetes. These findings highlight the associated comorbidities in this population, emphasizing the need for early detection and intervention.

[source] The Accuracy and Completeness of Data Collected by Prospective and Retrospective MethodsACADEMIC EMERGENCY MEDICINE, Issue 9 2005J. Tobias Nagurney MD Abstract Objectives: To describe and test a model that compares the accuracy of data gathered prospectively versus retrospectively among adult emergency department patients admitted with chest pain. Methods: The authors developed a model of information flow from subject to medical record to the clinical study case report form, based on a literature review. To test this model, a bidirectional (prospective and retrospective) study was conducted, enrolling all eligible adult patients who were admitted with a chief complaint of chest pain. The authors interviewed patients in the emergency department to determine their chest pain history and established a prospective database; this was considered the criterion standard. Then, patient medical records were reviewed to determine the accuracy and completeness of the information available through a retrospective medical record review. Results: The model described applies the concepts of reliability and validity to information passed on by the study subject, the clinician, and the medical record abstractor. This study was comprised of 104 subjects, of which 63% were men and the median age was 63 years. Subjects were uncertain of responses for 0,8% of questions and responded differently upon reinterview for subsets of questions 0,30% of the time. The sensitivity of the medical record for risk factors for coronary artery disease was 0.77 to 0.93. Among the 88 subjects (85%) who indicated that their chest pain was substernal or left chest, the medical record described this location in 44%. Timing of the chest pain was the most difficult item to accurately capture from the medical record. Conclusions: Information obtained retrospectively from the abstraction of medical records is measurably less accurate than information obtained prospectively from research subjects. For certain items, more than half of the information is not available. This loss of information is related to the data types included in the study and by the assumptions that a researcher performing a retrospective study makes about implied versus explicitly stated responses. A model of information flow that incorporates the concepts of reliability and validity can be used to measure some of the loss of information that occurs at each step along the way from subject to clinician to medical record abstractor. [source] Head injuries related to sports and recreation activities in school-age children and adolescents: Data from a referral centre in Victoria, AustraliaEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2010Louise M Crowe Abstract Objectives:, Head injuries (HI) in children are common and even mild HI can lead to ongoing cognitive and behavioural changes. We set out to determine the causes of sport-related HI in school-age children presenting to a large urban ED as a basis for future interventions. Method:, Identification and medical record review of all sport-related HI in children aged 6,16 years at a tertiary children's hospital ED in Victoria, Australia, over a 1 year period. Information was collected on demographics, injury variables and radiology findings. HI were classified as mild, moderate and severe based on GCS and radiography reports. Results:, Over 12 months there were 406 HI in school-age children. Seventy per cent were male. A large number of HI (129; 33%) were related to sports. Of these, most were classified as mild and 13% were classified as moderate or severe. Among a range of sports, Australian Rules football was associated with more than 30% of all HI attributable to a sport and recreation cause. Equestrian activities were the main cause of moderate HI. Conclusion:, The present study identified sports as a major cause of HI in the Victorian paediatric emergency setting with Australian Rules football the most commonly involved sport. Further prevention initiatives should consider targeting Australian Rules football and equestrian activities. [source] Validation of a brief screening instrument for the ascertainment of epilepsyEPILEPSIA, Issue 2 2010Ruth Ottman Summary Purpose:, To validate a brief screening instrument for identifying people with epilepsy in epidemiologic or genetic studies. Methods:, We designed a nine-question screening instrument for epilepsy and administered it by telephone to individuals with medical record,documented epilepsy (lifetime history of ,2 unprovoked seizures, n = 168) or isolated unprovoked seizure (n = 54), and individuals who were seizure-free on medical record review (n = 120), from a population-based study using Rochester Epidemiology Project resources. Interviewers were blinded to record-review findings. Results:, Sensitivity (the proportion of individuals who screened positive among affected individuals) was 96% for epilepsy and 87% for isolated unprovoked seizure. The false positive rate (FPR, the proportion who screened positive among seizure-free individuals) was 7%. The estimated positive predictive value (PPV) for epilepsy was 23%, assuming a lifetime prevalence of 2% in the population. Use of only a single question asking whether the subject had ever had epilepsy or a seizure disorder resulted in sensitivity 76%, FPR 0.8%, and estimated PPV 66%. Subjects with epilepsy were more likely to screen positive with this question if they were diagnosed after 1964 or continued to have seizures for at least 5 years after diagnosis. Discussion:, Given its high sensitivity, our instrument may be useful for the first stage of screening for epilepsy; however, the PPV of 23% suggests that only about one in four screen-positive individuals will be truly affected. Screening with a single question asking about epilepsy yields a higher PPV but lower sensitivity, and screen-positive subjects may be biased toward more severe epilepsy. [source] The Emergency Department Presentation of Patients with Active Pulmonary TuberculosisACADEMIC EMERGENCY MEDICINE, Issue 9 2000Peter E. Sokolove MD Abstract. Objective: To determine the clinical presentation of emergency department (ED) patients with active pulmonary tuberculosis (TB). Methods: This was a retrospective medical record review of adult patients, identified through infection control records, diagnosed as having active pulmonary TB by sputum culture over a 30-month period at an urban teaching hospital. The ED visits by these patients from one year before to one year after the initial positive sputum culture were categorized as contagious or noncontagious, using defined clinical and radiographic criteria. The medical records of patients with contagious visits to the ED were reviewed to determine chief complaint, presence of TB risk factors and symptoms, and physical examination and chest radiograph findings. Results: During the study period, 44 patients with active pulmonary TB made 66 contagious ED visits. Multiple contagious ED visits were made by 12 patients (27%; 95% CI = 15% to 43%). Chief complaints were pulmonary 33% (95% CI = 22% to 46%), medical but nonpulmonary 41% (95% CI = 29% to 54%), infectious but nonpulmonary 14% (95% CI = 6% to 24%), and traumatic/orthopedic 12% (95% CI = 5% to 22%). At least one TB risk factor was identified in 57 (86%; 95% CI%= 76 to 94%) patient visits and at least one TB symptom in 51 (77%; 95% CI = 65% to 87%) patient visits. Cough was present during only 64% (95% CI = 51% to 75%) of the patient visits and hemoptysis during 8% (95% CI = 3% to 17%). Risk factors and symptoms that, if present, were likely to be detected at triage were foreign birth, homelessness, HIV positivity, hemoptysis, and chest pain. Conclusions: Patients with active pulmonary TB may have multiple ED visits, and often have nonpulmonary complaints. Tuberculosis risk factors and symptoms are usually present in these patients but often missed at ED triage. The diversity of clinical presentations among ED patients with pulmonary TB will likely make it difficult to develop and implement high-yield triage screening criteria. [source] Importance of comorbidity in hypopharyngeal cancer,HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2010Akihiro Homma MD Abstract Background. Comorbidity has an impact on survival in laryngeal cancer in several reports. However, the importance of comorbidity in hypopharyngeal cancer (HPC) has not been reported. Methods. A retrospective medical record review of 156 patients with HPC treated between 1995 and 2005 was performed. Comorbid illness was measured by the Adult Comorbidity Evaluation-27. A Cox proportional hazards model was used to determine the factors related to overall survival. Results. Comorbidity was absent in 55 (35.2%) of the patients, mild in 39 (25%), moderate in 28 (17.9%), and severe in 34 (21.8%). There were statistically significant differences between the survival rates in accord with age, stage, subsite, and comorbidity (45.1% for none or mild vs 27.7% for moderate or severe; p = .0073). Age, stage, and comorbidity were identified as independent prognostic factors in the multivariate analysis. Conclusion. Comorbidity, along with the clinical stage, should be considered in treatment planning for patients with HPC. © 2009 Wiley Periodicals, Inc. Head Neck, 2010 [source] Development and Validation of a Risk-Adjustment Tool in Acute AsthmaHEALTH SERVICES RESEARCH, Issue 5p1 2009Chu-Lin Tsai Objective. To develop and prospectively validate a risk-adjustment tool in acute asthma. Data Sources. Data were obtained from two large studies on acute asthma, the Multicenter Airway Research Collaboration (MARC) and the National Emergency Department Safety Study (NEDSS) cohorts. Both studies involved >60 emergency departments (EDs) and were performed during 1996,2001 and 2003,2006, respectively. Both included patients aged 18,54 years presenting to the ED with acute asthma. Study Design. Retrospective cohort studies. Data Collection. Clinical information was obtained from medical record review. The risk index was derived in the MARC cohort and then was prospectively validated in the NEDSS cohort. Principle Findings. There were 3,515 patients in the derivation cohort and 3,986 in the validation cohort. The risk index included nine variables (age, sex, current smoker, ever admitted for asthma, ever intubated for asthma, duration of symptoms, respiratory rate, peak expiratory flow, and number of beta-agonist treatments) and showed satisfactory discrimination (area under the receiver operating characteristic curve, 0.75) and calibration ( p=.30 for Hosmer,Lemeshow test) when applied to the validation cohort. Conclusions. We developed and validated a novel risk-adjustment tool in acute asthma. This tool can be used for health care provider profiling to identify outliers for quality improvement purposes. [source] Presentations by youth to Auckland Emergency Departments following a suicide attemptINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 3 2002Sara Bennett ABSTRACT: The objective of this study was to describe the population of European youth (15,24 years) presenting to emergency departments (EDs) at one of the three Auckland public hospitals following attempted suicide; and to identify factors associated with presentations to EDs by these youth. A 1-year medical record review was undertaken. A total of 212 presentations (196 individuals) occurred during the surveillance; alcohol was present for 29%. Attempts involving alcohol were more likely to occur at weekends (P < 0.01); involve cutting and piercing (P < 0.05); be undertaken by employed people (P < 0.05), and be undertaken by those not residing with family (P < 0.01). Two groups of particular concern were identified: those who involved alcohol in their attempt; and those who represented during the study period following multiple suicide attempts. These findings have implications for immediate care within an ED setting, and long-term follow-up healthcare options for distressed young people. [source] Impoverished Children With Asthma: A Pilot Study of Urban Healthcare AccessJOURNAL FOR SPECIALISTS IN PEDIATRIC NURSING, Issue 2 2004Andrea Wallace ND ISSUES AND PURPOSE Using Andersen's Behavioral Model of Health Care Use, this pilot study was conducted to better understand the experiences of children with asthma as they access an urban healthcare system. DESIGN AND METHODS This descriptive study used a convenience sample of 34 families of pediatric asthma patients who participated in semistructured interviews and closed medical record review. RESULTS Only one patient reported having a written exacerbation management plan. Beliefs regarding medication addiction and side effects were frequently reported as barriers to medication adherence, and children seeking asthma care in primary care settings saw many care providers. PRACTICE IMPLICATIONS Exploring how expanded nursing roles can help address both family and system factors serving as barriers to health care ought to be a key priority for nursing. [source] Clinical and Economic Outcomes of Infants Receiving Breast Milk in the NICUJOURNAL FOR SPECIALISTS IN PEDIATRIC NURSING, Issue 1 2001Amy J. Barton ISSUES AND PURPOSE. This study compared clinical and economic outcomes for infants who were exclusively fed breast milk and infants who were fed commercial formula. DESIGN AND METHODS. A retrospective medical record review from a regional neonatal intensive care unit (N = 80) using consultation logs from the lactation coordinator and a matched sample of formula-fed infants. RESULTS. Neither clinical (weight gain, length of stay, days of parenteral nutrition) nor economic outcomes (direct variable costs, net revenue) differed significantly between the groups. PRACTICE IMPLICATIONS. While it may not be possible to demonstrate sufficient cost savings while the infant resides within the NICU to justify a lactation coordinator, long-term clinical and economic outcomes may be sensitive to this specialized nursing service. [source] Pneumonia Versus Aspiration Pneumonitis in Nursing Home Residents: Prospective Application of a Clinical AlgorithmJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2005Joseph M. Mylotte MD Objectives: To prospectively evaluate a clinical algorithm for the diagnosis of pneumonitis and pneumonia in nursing home residents. Design: Prospective cohort study. Setting: Inpatient geriatrics unit. Participants: Nursing home residents admitted to the hospital with suspected pneumonia. Measurements: Identification of pneumonitis and pneumonia using the algorithm; medical record review and abstraction of clinical data; hospital outcome and length of stay. Results: One hundred seventy episodes of suspected pneumonia were screened with the algorithm and classified into four groups: 25% pneumonia, 28% aspiration pneumonitis of 24 hours or less duration, 12% aspiration pneumonitis of more than 24 hours' duration, and 35% an aspiration event without pneumonitis. Presenting symptoms and signs, laboratory tests, severity of illness measures, or serum C-reactive protein levels did not distinguish between the four groups. Those with an aspiration event without pneumonitis tended to be treated less often with antibiotic therapy after admission (P=.004) and after discharge (P=.01). Of those who survived, there was no significant difference in mean hospital length of stay between the four groups. There was no significant difference in the percentage of case fatality between the four groups, but those with aspiration pneumonitis of 24 hours or less duration and with an aspiration event without pneumonitis had a lower mortality than the other two groups. Conclusion: Distribution of episodes of suspected pneumonia by clinical category as determined using the algorithm was similar to that of the derivation study, as were case fatality rates in each category. These findings suggest that the algorithm may be useful for making the distinction between pneumonitis and pneumonia in nursing home residents; further studies are warranted. [source] The Effects of Staffing on In-Bed Times of Nursing Home ResidentsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2004Barbara M. Bates-Jensen PhD, CWOCN Objectives: To examine the effect of staffing level on time observed in bed during the daytime in nursing home (NH) residents. Design: Descriptive, cross-sectional study. Setting: Thirty-four southern California NHs. Participants: A total of 882 NH residents: 837 had hourly observation data, 777 had mealtime observations, 837 completed interviews, and 817 completed a physical performance test. Measurements: Cross-sectional data collected from participants at each NH site included direct observations (hourly and mealtime), resident interviews, medical record review, and physical performance tests. Results: In multivariate analyses, staffing level remained the strongest predictor of time observed in bed after controlling for resident functional measures (odds ratio=4.89; P=.042). Residents observed in bed during the daytime in more than 50% of hourly observations were observed also to experience increased daytime sleeping (P<.001) and less social engagement (P=.026) and consumed less food and fluids during mealtimes than those observed in bed in less than 50% of observations, after adjusting for resident function (P<.001). Conclusion: In this sample of NHs, resident functional measures and NH staffing level predicted observed time in bed according to hourly observations, with staffing level the most powerful predictor. Neither of these predictors justifies the excessive in-bed times observed in this study. Staff care practices relevant to encouraging residents to be out of bed and resident preferences for being in bed should be examined and improved. Practice recommendations regarding in-bed time should be considered, and further research should seek to inform the development of such recommendations. [source] Predictive Value of Nonspecific Symptoms for Acute Illness in Nursing Home ResidentsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2003Kenneth S. Boockvar MD OBJECTIVES: To examine the predictive value of nonspecific symptoms for acute illness in nursing home residents. DESIGN: Prospective, observational study. SETTING: Academic nursing home located in an urban setting. PARTICIPANTS: Two hundred two newly admitted residents. MEASUREMENTS: Eleven nonspecific symptoms were ascertained by review of observations documented by nursing home staff in the medical record. Research staff independently identified acute illness according to previously established criteria from nurse report and medical record review. Follow-up was divided into 10-day intervals, and concordance between nonspecific symptoms and acute illness within these intervals was determined. Predictive values were calculated according to standard formulae. RESULTS: Nonspecific symptoms and acute illnesses occurred in 21.7% and 12.5% of 10-day intervals, respectively. Positive predictive values (PPVs) were highest for lethargy, weakness, and decreased appetite, each of which correctly predicted the presence of an acute illness one out of two times the symptoms were reported. Agitation and disorientation predicted an acute illness one out of three times, and falls predicted an acute illness one out of four times. Overall, the PPV of the occurrence of any nonspecific symptom was 0.24, and the negative predictive value of the absence of nonspecific symptoms was 0.91. CONCLUSION: Hypoactive nonspecific symptoms are more likely than other nonspecific symptoms to be signs of incipient acute illness. Studies are needed to determine whether an intervention in residents with these nonspecific symptoms can enable earlier detection and treatment of acute illness. [source] Fracture Risk in Type 2 Diabetes: Update of a Population-Based Study,,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 8 2008L Joseph Melton III Abstract We found no significant excess of fractures among Rochester, MN, residents with diabetes mellitus initially recognized in 1950,1969, but more recent studies elsewhere have documented an apparent increase in hip fracture risk. To explore potential explanations for any increase in fractures, we performed an historical cohort study among 1964 Rochester residents who first met glycemic criteria for diabetes in 1970,1994 (mean age, 61.7 ± 14.0 yr; 51% men). Fracture risk was estimated by standardized incidence ratios (SIRs), and risk factors were evaluated in Andersen-Gill time-to-fracture regression models. In 23,236 person-years of follow-up, 700 diabetic residents experienced 1369 fractures documented by medical record review. Overall fracture risk was elevated (SIR, 1.3; 95% CI, 1.2,1.4), but hip fractures were increased only in follow-up beyond 10 yr (SIR, 1.5; 95% CI, 1.1,1.9). As expected, fracture risk factors included age, prior fracture, secondary osteoporosis, and corticosteroid use, whereas higher physical activity and body mass index were protective. Additionally, fractures were increased among patients with neuropathy (hazard ratio [HR], 1.3; 95% CI, 1.1,1.6) and those on insulin (HR, 1.3; 95% CI, 1.1,1.5); risk was reduced among users of biquanides (HR, 0.7; 95% CI, 0.6,0.96), and no significant influence on fracture risk was seen with sulfonylurea or thiazolidinedione use. Thus, contrary to our earlier study, the risk of fractures overall (and hip fractures specifically) was increased among Rochester residents with diabetes, but there was no evidence that the rise was caused by greater levels of obesity or newer treatments for diabetes. [source] Administration of enoxaparin by continuous infusion in a naturalistic setting: analysis of renal function and safety,JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 3 2005S. L. Kane-Gill Pharm D MSc Summary Study objective:, To describe the clinical use and safety of continuous infusion (CI) enoxaparin in a naturalistic setting and to evaluate the influence of renal function on enoxaparin elimination. Design:, Retrospective medical record review. Setting:, 1000-bed tertiary care teaching centre. Patients:, Hospitalized patients that received enoxaparin by CI during a 2-year period. Interventions:, None. Measurements:, Specific details of dosage and monitoring were collected. Adverse drug reactions (ADR) were recorded. Creatinine clearance (CrCl) was calculated using Cockroft and Gault and Brater equations. A population pharmacokinetic analysis was performed using the non-linear mixed effect model (NONMEM). For patients located in the intensive care unit (ICU) and ward, POSTHOC pharmacokinetic parameter estimates were evaluated using the Wilcoxon rank-sum. Pearson correlation coefficient was calculated to determine the association between renal function and anti-Xa clearance. Main results:, Sixty-seven patients received enoxaparin by CI of which 61·2% were in the ward and 38·8% in the ICU. The average initial rate and duration of infusion were 5·2 mg/h and 5·6 days, respectively. The number of anti-Xa concentration measurements averaged five per patient. Nine patients experienced an ADR. The most frequent ADR was gastrointestinal bleeding (n = 4). Among the 67 patients, 48 had available anti-Xa concentrations and were included in the NONMEM model. The anti-Xa CL and volume of distribution for ICU and ward patients averaged 0·64 ± 0·34 L/h, 10·6 ± 1·55 L and 1·01 ± 0·39 L/h, 9·08 ± 1·17 L, respectively. CrCl was not a significant covariate when included in the NONMEM model, and the association between CrCl and anti-Xa clearance was not significant (R2 = 0·0005; P = 0·8916). Conclusions:, This study is the first to report the use and safety of prolonged CI enoxaparin. Pharmacokinetic parameters of enoxaparin differ in ICU vs. ward patients. Overall, we found the safety of CI to be comparable to subcutaneous administration. Also, we found no effect of renal function on enoxaparin elimination. [source] Coding diagnoses and procedures using a high-quality clinical database instead of a medical record reviewJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 3 2001Carl van Walraven MSc MD FRCPC Abstract A discharge abstract must be completed for each hospitalization. The most time-consuming component of this task is a complete review of the doctors' progress notes to identify and code all diagnoses and procedures. We have developed a clinical database that creates hospital discharge summaries. To compare diagnostic and procedural coding from a clinical database vs. the standard chart review by health records analysts (HRA). All patients admitted and discharged from general medical and surgical services at a teaching hospital in Ontario, Canada. Diagnostic and procedural codes were identified by reviewing discharge summaries generated from a clinical database. Independently, codes were identified by hospital health records analysts using chart review alone. Codes were compared with a gold standard case review conducted by a health records analyst and a doctor. Coding accuracy (percentage of codes in gold standard review) and completeness (percentage of gold standard codes identified). The study included 124 patients (mean length of stay 5.5 days; 66.4% medical patients). The accuracy of the most responsible diagnosis was 68.5% and 62.9% for the database (D) and chart review (C), respectively (P = 0.18). Overall, the database significantly improved the accuracy (D = 78.9% vs. C = 74.5%; P = 0.02) and completeness (D = 63.9% vs. C = 36.7%; P < 0.0001) of diagnostic coding. Although completeness of procedural coding was similar (D = 5.4% vs. C = 64.2%; P = NS), accuracy decreased with the database (D = 70.3% vs. C = 92.2%; P < 0.0001). Mean resource intensity weightings calculated from the codes (D = 1.3 vs. C = 1.4; P = NS) were similar. Coding from a clinical database may circumvent the need for HRAs to review doctors' progress notes, while maintaining the quality of coding in the discharge abstract. [source] Predictive Factors and the Effect of Phenoxybenzamine on Outcome in Dogs Undergoing Adrenalectomy for PheochromocytomaJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 6 2008M.A. Herrera Background: Some studies in dogs undergoing adrenalectomy for pheochromocytoma suggest that anesthetic complications and perioperative mortality are common. In humans, surgical outcome has improved with the use of phenoxybenzamine (PBZ) before adrenalectomy. Hypothesis: Dogs treated with PBZ before adrenalectomy have increased survival compared with untreated dogs. Animals: Forty-eight dogs that underwent adrenalectomy for pheochromocytoma. Methods: A retrospective medical record review for dogs that underwent adrenalectomy for pheochromocytoma at a veterinary medical teaching hospital over the period from January 1986 through December 2005. Results: Twenty-three of 48 dogs were pretreated with PBZ (median dosage: 0.6 mg/kg PO q12h) for a median duration of 20 days before adrenalectomy. Duration of anesthesia and surgery, percentage of dogs with pheochromocytoma involving the right versus left adrenal gland, size of tumor, and presence of vascular invasion were similar for PBZ-treated and untreated dogs. Thirty-three (69%) of 48 dogs survived adrenalectomy in the perioperative period. PBZ-treated dogs had a significantly (P= .014) decreased mortality rate compared with untreated dogs (13 versus 48%, respectively). Additional significant prognostic factors for improved survival included younger age (P= .028), lack of intraoperative arrhythmias (P= .0075), and decreased surgical time (P= .0089). Conclusions and Clinical Importance: Results from this retrospective study support treatment with PBZ before surgical removal of pheochromocytoma in dogs. [source] Serious Bacterial Infection in Recently Immunized Young Febrile InfantsACADEMIC EMERGENCY MEDICINE, Issue 12 2009Margaret Wolff MD Abstract Objective:, The objective of this study was to investigate the prevalence of serious bacterial infection (SBI) in febrile infants without a source aged 6,12 weeks who have received immunizations in the preceding 72 hours. Methods:, The authors conducted a medical record review of infants aged 6,12 weeks with a fever of ,38.0°C presenting to the pediatric emergency department (ED) over 88 months. Infants were classified either as having received immunizations within the 72 hours preceding the ED visit (recent immunization [RI]) or as not having received immunizations during this time period (no recent immunization [NRI]). Primary outcome of an SBI was based on culture results; only patients with a minimum of blood and urine cultures were studied. Results:, A total of 1,978 febrile infants were studied, of whom 213 (10.8%) had received RIs. The overall prevalence of definite SBI was 6.6% (95% confidence interval [CI] = 5.5 to 7.7). The prevalence of definite SBI in NRI infants was 7.0% (95% CI = 5.9 to 8.3) compared to 2.8% (95% CI = 0.6 to 5.1) in the RI infants. The prevalence of definite SBI in febrile infants vaccinated in the preceding 24 hours decreased to 0.6% (95% CI = 0 to 1.9). The prevalence of definite SBI in febrile infants vaccinated greater than 24 hours prior to presentation was 8.9% (95 CI = 1.5 to 16.4). The relative risk of SBI with RI was 0.41 (95% CI = 0.19 to 0.90). All SBIs in the RI infants were urinary tract infections (UTI). Conclusions:, Among febrile infants, the prevalence of SBI is less in the initial 24 hours following immunizations. However, there is still a substantial risk of UTI. Therefore, urine testing should be considered in febrile infants who present within 24 hours of immunization. Infants who present greater than 24 hours after immunizations with fever should be managed similarly to infants without RIs. [source] Risk factors for the development of bronchiectasis in HIV-infected childrenPEDIATRIC PULMONOLOGY, Issue 10 2007David M. Berman DO Abstract Our objective was to describe the risk factors for the development of bronchiectasis in HIV-1 infected children. This study was a retrospective, case controlled study based upon medical record review of HIV-1 infected children receiving primary care at a single large, urban medical center in Miami, Florida. Cases (HIV-1 infected children who developed bronchiectasis while being cared for between January 1982 and September 2000) were matched 1:3 (birth,±,24 months) with controls (HIV-1 infected children without bronchiectasis). Variables analyzed including number of episodes of pneumonia (including Pneumocystis jiroveci pneumonitis [PCP], lymphoid interstitial pneumonitis (LIP), and CDC category of immunosuppression) were noted in both cases and controls until the age at which the cases developed bronchiectasis. Of the 749 patients whose charts were reviewed, 43 met the case definition for bronchiectasis and 19 met the eligibility criteria for this study. Fifty-seven controls were randomly selected from the patients without bronchiectasis. Cases were more likely to have experienced recurrent pneumonia than the controls; 17 (89.5%) versus 5 children (8.8%) respectively (P -value ,0.001) as well as a greater mean number of episodes of pneumonia 8.2 (range, 4,13) versus 1.45 (range, 0,9) respectively (CI,=,(5.58,7.82); P -value ,0.001). Cases were more likely to have progressed to CDC immunological category 3 than the controls; 19 (100%) versus 32 (56%) children respectively (P -value <0.001). LIP occurred more frequently in the cases than in the controls; 14/19 (73.6%) versus 19/57 (33.3%), respectively (P -value,=,0.005). HIV-1 infected children with a history of recurrent pneumonia, profound immuno-suppression (CDC immunologic category 3), and LIP appear to have a higher risk of developing bronchiectasis.

Simpson MD Abstract Background Coexisting food allergy and asthma is a significant problem in the pediatric population. Studies have looked at the association between food sensitization and asthma severity. It is unknown whether specific food allergies are associated with increased asthma morbidity. Objective We studied the independent effect that allergy to egg, milk, fish, and peanut has on the number of hospitalizations and courses of systemic steroids in children with asthma. Methods We performed a medical record review to evaluate the effect food allergy to egg, fish, peanut, and milk has on asthma morbidity. We reviewed the records of 201 children aged 3 months to 14 years with the diagnosis of asthma (ICD-9 codes 493.90, 493.91, and 493.92), of which 88 had coexistent food allergy. All children in the food allergy group had food-specific IgE concentrations greater than the 95% positive predictive value. We compared the rate of hospitalizations and use of systemic steroids between children with asthma and food allergies and those without coexisting food allergy using direct-entry, multiple regression analysis. Patients were adjusted for the severity of their asthma based on symptoms documented at their first visit to the allergist according to the National Asthma Education and Prevention Program guidelines and presence of environmental allergy, eczema, smoke exposure, and gastroesophageal reflux. Results Peanut and milk allergies were both associated with increased number of hospitalizations (P,=,0.009, 0.016), and milk allergy was associated with increased use of systemic steroids (P,=,0.001). Conclusion Peanut and milk allergies were associated with increased hospitalization and steroid use and may serve as early markers for increased asthma morbidity.

[source] Hepatitis B vaccine and risk of autoimmune thyroid disease: a Vaccine Safety Datalink study,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 7 2007Onchee Yu MS Abstract Purpose Hepatitis B vaccine has been postulated as a possible cause of autoimmune disorders, including autoimmune thyroid diseases (ATD). Cases of Graves' disease and Hashimoto's thyroiditis, following hepatitis B vaccine have been reported to the Vaccine Adverse Events Reporting System (VAERS). To test the hypothesis that hepatitis B vaccine increases the risk of ATD, we conducted a case-control study, within the Vaccine Safety Datalink project. Methods We identified potential cases of Graves' disease and Hashimoto's thyroiditis, among persons aged 18,69 years from administrative data recorded by three health maintenance organizations (HMOs) and verified cases by medical record review. Controls were frequency-matched to cases by birth year, sex, and study site. Vaccine information was collected from administrative records, chart review, and telephone interviews with study subjects. We enrolled 355 Graves' disease cases, 418 Hashimoto's thyroiditis cases, and 1102 controls. We assessed the association between ever-receipt of hepatitis B vaccine, as well as receipt of hepatitis B vaccine less than 1 year, 1,5 years and at least 5 years prior to the index date, and the risk of ATD. Results Ever-receipt of hepatitis B vaccine was not associated with risk of Graves' disease (odds ratio (OR), 0.90; 95% confidence interval (CI), 0.62,1.32) or Hashimoto's thyroiditis (OR, 1.23; 95%CI, 0.87,1.73). There was also no association between the time interval since receipt of hepatitis B vaccination and either outcome. Conclusions We did not observe an increased risk of Graves' disease or Hashimoto's thyroiditis, following receipt of hepatitis B vaccine. Copyright © 2007 John Wiley & Sons, Ltd. [source] Achilles tendon rupture and its association with fluoroquinolone antibiotics and other potential risk factors in a managed care populationPHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 11 2006DrPH, John D. Seeger Pharm D Abstract Background Case reports and observational studies have implicated fluoroquinolone antibiotic exposure as a risk factor for Achilles tendon rupture (ATR), an uncommon condition for which there are few formal studies. We sought to quantify the strength of association between exposure to fluoroquinolone antibiotics and the occurrence of ATR, accounting for other risk factors. Methods This was a case-control study nested within a health insurer cohort. Cases of ATR were identified and confirmed using patterns of health insurance claims that were validated through sampled medical record review. Information on risk factors, including fluoroquinolone exposure, came from health insurance claims. Results There were 947 cases of ATR and 18,940 controls. A dispensing of a fluoroquinolone antibiotic in the past 6 months was more common among ATR cases than controls, although not significantly so (odds ratio (OR),=,1.2; 95% confidence interval (CI),=,0.9,1.7), and exposure to a higher cumulative fluoroquinolone dose was more strongly associated (OR,=,1.5, 95%CI,=,1.0,2.3). Other risk factors for ATR were trauma (OR,=,17.2, 95%CI,=,14.0,20.2), male sex (OR,=,3.0, 95%CI,=,2.6,3.5), injected corticosteroid administration (OR,=,2.2, 95%CI,=,1.6,2.9), obesity (OR,=,2.0, 95%CI,=,1.2,3.1), rheumatoid arthritis (OR,=,1.9, 95%CI,=,1.0,3.7), skin or soft tissue infections (OR,=,1.5, 95%CI,=,0.9,2.3), oral corticosteroids (OR,=,1.4, 95%CI,=,1.0,1.8), and non-fluoroquinolone antibiotics (OR,=,1.2, 95%CI,=,1.1,1.5). Conclusions The elevation in ATR risk associated with fluoroquinolones was similar in magnitude to that associated with oral corticosteroids or non-fluoroquinolone antibiotics. Trauma and male sex were more strongly associated with ATR, as were obesity and injected corticosteroids. Copyright © 2006 John Wiley & Sons, Ltd. [source] The comparative safety of rosuvastatin: a retrospective matched cohort study in over 48,000 initiators of statin therapy,PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 7 2006Andrew T. McAfee MD Abstract Purpose The purpose of this study was to compare incidence rates of hospitalization associated with rhabdomyolysis, myopathy, renal, or hepatic dysfunction, and of in-hospital death, between initiators of rosuvastatin and other statins. Methods This was a matched cohort study of statin initiators from the administrative database of a large health insurer in the US, during the first 6 months of rosuvastatin availability with up to 18 months of follow-up. All outcome events were verified by medical record review. Incidence rates, risk ratios, and associated 95% confidence intervals were estimated. Results From an initial pool of 12,217, 11,249 eligible rosuvastatin initiators were matched to 37,282 initiators of other statins. The incidence rate (IR) per 1000 person-years for rhabdomyolysis was 0.10 [0.00, 0.55] for rosuvastatin initiators (n,=,1) and 0.06 [0.01, 0.22] for other statin initiators (n,=,2), for a hazard ratio (HR) of 1.98 [0.18, 21.90]. The IR for myopathy was 0.20 [0.02, 0.71] for rosuvastatin initiators (n,=,2) and 0.00 [0.00, 0.09] for other statin initiators (n,=,0). The IR for renal dysfunction was 1.18 [0.61, 2.06] for rosuvastatin initiators (n,=,12) and 1.26 [0.91, 1.71] for other statin initiators (n,=,42), for a HR of 0.90 [0.47, 1.73]. The IR for hepatic dysfunction was 0.20 (0.02, 0.71) for rosuvastatin initiators (n,=,2) and 0.24 (0.10, 0.47) for other statin initiators (n,=,8), for a HR of 0.87 (0.18, 4.14). Conclusions This study found no difference between rosuvastatin and the other statins in the incidence of hospitalizations associated with renal or hepatic events, or death. The absolute incidence rates of rhabdomyolysis and myopathy were reassuringly low among all statin initiators but remain too small for firm conclusions to be drawn on any difference between the statins.

[source] Rosuvastatin safety: a comprehensive, international pharmacoepidemiology programme,,§PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 7 2006Saga Johansson MD Abstract Results from clinical trials and clinical practice have shown statins to be generally well tolerated with a low frequency of clinically relevant side effects. Nevertheless, there are rare occasions when adverse events (AEs), sometimes serious, may occur. Rosuvastatin is the newest statin to be approved in the USA and many other countries. As part of the continued assessment of the benefit-risk profile of rosuvastatin, AstraZeneca has developed a progressive, comprehensive pharmacoepidemiology programme to complement safety data obtained from randomised clinical trials and spontaneous reporting systems, which have demonstrated that rosuvastatin has a safety profile in line with comparator statins. This programme comprises nine studies conducted in recognised centres of excellence assessing over 50,000 patients treated with rosuvastatin. It consists of three components: patient characteristics studies (four studies), safety evaluation studies (four studies); and review of data generated from the Prescription-Event Monitoring (PEM) study, designed and run by an independent third party. Patient characteristics studies are designed to describe the characteristics and drug utilisation patterns of new users of rosuvastatin compared with new users of other statins in automated databases. Safety evaluation studies will examine the rates of specific AEs in different cohorts of statin users and determine risk factors for these events using data recorded prospectively in automated databases with case adjudication via medical record review. The independent PEM study will monitor any significant events recorded by general practitioners since starting rosuvastatin treatment. This article is an overview of the rationale and methodology of the rosuvastatin pharmacoepidemiology programme. Copyright © 2006 John Wiley & Sons, Ltd. [source] | ||||||||||||||||||||||||||||
