Selected AbstractsModerators and mediators of two brief interventions for alcohol in the emergency departmentADDICTION, Issue 3 2010Nancy P. Barnett ABSTRACT Objective To evaluate moderators and mediators of brief alcohol interventions conducted in the emergency department. Methods Patients (18,24 years; n = 172) in an emergency department received a motivational interview with personalized feedback (MI) or feedback only (FO), with 1- and 3-month booster sessions and 6- and 12-month follow-ups. Gender, alcohol status/severity group [ALC+ only, Alcohol Use Disorders Identification Test (AUDIT+) only, ALC+/AUDIT+], attribution of alcohol in the medical event, aversiveness of the event, perceived seriousness of the event and baseline readiness to change alcohol use were evaluated as moderators of intervention efficacy. Readiness to change also was evaluated as a mediator of intervention efficacy, as were perceived risks/benefits of alcohol use, self-efficacy and alcohol treatment seeking. Results Alcohol status, attribution and readiness moderated intervention effects such that patients who had not been drinking prior to their medical event, those who had low or medium attribution for alcohol in the event and those who had low or medium readiness to change showed lower alcohol use 12 months after receiving MI compared to FO. In the AUDIT+ only group those who received MI showed lower rates of alcohol-related injury at follow-up than those who received FO. Patients who had been drinking prior to their precipitating event did not show different outcomes in the two interventions, regardless of AUDIT status. Gender did not moderate intervention efficacy and no significant mediation was found. Conclusions Findings may help practitioners target patients for whom brief interventions will be most effective. More research is needed to understand how brief interventions transmit their effects. [source] Keeping your globally mobile employees healthy, safe, and secureGLOBAL BUSINESS AND ORGANIZATIONAL EXCELLENCE, Issue 1 2009Myles Druckman Companies are sending higher numbers of older employees to difficult or dangerous locations, which increases the chances of a medical event where healthcare services are least available. Business travelers and international assignees and their employers need to adequately assess and prepare for such possibilities. The author describes five key processes that will help companies perform duty of care and minimize risks to the employee and company alike; the elements of a best-practice international preassignment health program to ensure assignees are fit for work in locations with high medical risk; and the five responsibilities of globally mobile employees for protecting their health and getting medical help if they need it. © 2009 Wiley Periodicals, Inc. [source] A prospective observational study of a cohort of outpatients with an acute medical event and reduced mobility: incidence of symptomatic thromboembolism and description of thromboprophylaxis practicesJOURNAL OF INTERNAL MEDICINE, Issue 2 2006J.-L. BOSSON Abstract. Objectives., The study was performed to determine the incidence of symptomatic venous thromboembolism in outpatients with an acute medical event causing temporary reduced mobility. Risk factors for venous thromboembolism and thromboprophylaxis practices were also studied. Design., This was a prospective, observational, multicentre, cohort study. Setting., General practitioners randomly selected from a registry of 25 000 active representative doctors in France included eligible outpatients Subjects., Outpatients aged at least 40 years anticipated to have reduced mobility for at least 48 h due to an acute medical event were eligible. Interventions., None required. Main outcome measures., Symptomatic deep-vein thrombosis and pulmonary embolism at 3 weeks were the main study end-points. Results., Overall, 16 532 evaluable patients of mean age 71 years were recruited between October 2002 and June 2003 by 2895 doctors. The main acute medical events leading to reduced mobility were infection, acute rheumatism and falls without fracture. The incidence rates (95% confidence interval) of symptomatic deep-vein thrombosis and pulmonary embolism were 1% (0.84,1.14) and 0.20% (0.13,0.27) respectively. Venous insufficiency in legs, cancer, and a personal or family history of venous thromboembolism were independent risk factors for venous thromboembolism. Pharmacological thromboprophylaxis was initiated in 35.0% (n = 5782) of the patients. The principal driver of prescription was a personal history of venous thromboembolism. Conclusions., The risk of symptomatic venous thromboembolism in outpatients with reduced mobility for medical reasons is close to that reported in medical and surgical inpatients. This risk and the potential need for thromboprophylaxis should be taken into account by primary care doctors. [source] Implementation of an Emergency Department,based Transient Ischemic Attack Clinical Pathway: A Pilot Study in Knowledge TranslationACADEMIC EMERGENCY MEDICINE, Issue 11 2007Michael D. Brown MD Objectives To assess the feasibility of implementing an emergency department (ED),based transient ischemic attack (TIA) clinical pathway that uses computer-based clinical support, and to evaluate measures of quality, safety, and efficiency. Methods This was a prospective cohort study of adult patients presenting to a community ED with symptoms consistent with acute TIA. Adherence to the clinical pathway served as a test of feasibility. Compliance with guideline recommendations for antithrombotic therapy and vascular imaging were used as process measures of quality. The 90-day risk of recurrent TIA, stroke, or death provided estimates of safety. Efficiency was assessed by measuring the rate of uneventful hospitalization, defined as a hospital admission that did not result in any major medical event or vascular intervention such as endarterectomy or stent placement. Results Of the 75 subjects enrolled, physician adherence to the clinical pathway was 85.3%, and 35 patients (46.7%) were discharged home from the ED. Antithrombotic agents were prescribed to 68 (90.7%), and vascular imaging was performed in 70 (93.3%). The 90-day risk of recurrent TIA was seven out of 75 (9.3%; 95% confidence interval [CI] = 4.6% to 18.0%), one patient experienced stroke (1.3%; 95% CI = 0.2% to 7.2%), and three patients died (4.0%; 95% CI = 1.4% to 11.1%). Uneventful hospitalization occurred in 38 of 40 patients (95.0%). Conclusions Implementation of a clinical pathway for the evaluation and management of TIA using computer-based clinical support is feasible in a community ED setting. This pilot study in knowledge translation provides a design framework for further studies to assess the safety and efficiency of a structured ED-based TIA clinical pathway. [source] Etiology of strokes in children with sickle cell anemiaDEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 3 2006Michael R. DeBaun Abstract The most devastating complication of sickle cell anemia is cerebral infarction, affecting ,30% of all individuals with sickle cell anemia. Despite being one of the most common causes of stroke in infants and children, the mechanism of cerebral infarction in this population has not been extensively studied and is poorly understood. Multiple, synergistic factors are important in the pathogenesis of stroke including the hemodynamic effects of cerebral arterial occlusive disease, viscosity, chronic and acute anemia and acute medical events. This review focuses on the relationship between these factors in order to provide a foundation for further study of the etiology of strokes in this high-risk population.

[source] Trends and determinants of severe morbidity in HIV-infected patients: the ANRS CO3 Aquitaine Cohort, 2000,2004,HIV MEDICINE, Issue 8 2007F Bonnet Objective The aim of the study was to characterize the causes, trends and determinants of severe morbidity in a large cohort of HIV-infected patients between 2000 and 2004. Method Severe morbid events were defined as medical events associated with hospitalization or death. Epidemiological and biological data were recorded at the time of the morbid event. Trends were estimated using Poisson regression. Results Among 3863 individuals followed between 2000 and 2004, 1186 experienced one or more severe events, resulting in 1854 hospitalizations or deaths. The severe events recorded included bacterial infections (21%), AIDS events (20%), psychiatric events (10%), cardiovascular events (9%), digestive events including cirrhosis (7%), viral infections (6%) and non-AIDS cancers (5%). Between 2000 and 2004, the incidence rate of AIDS events decreased from 60 to 20 per 1000 person-years, that of bacterial infections decreased from 45 to 24 per 1000 person-years, and that of psychiatric events decreased from 26 to 14 per 1000 person-years (all P<0.01), whereas the incidences of cardiovascular events and of non-AIDS cancers remained stable at 14 and 10 per 1000 person-years, on average, respectively. Conclusion Severe morbidity has shifted from AIDS-related to non-AIDS-related events during the course of HIV infection in developed countries. Limiting endpoints to AIDS events and death is insufficient to describe HIV disease progression in the era of combination antiretroviral therapy. [source] The economic consequences of noncompliance in cardiovascular disease and related conditions: a literature reviewINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 2 2008N. Muszbek Summary Objectives:, To review studies on the cost consequences of compliance and/or persistence in cardiovascular disease (CVD) and related conditions (hypertension, dyslipidaemia, diabetes and heart failure) published since 1995, and to evaluate the effects of noncompliance on healthcare expenditure and the cost-effectiveness of pharmaceutical interventions. Methods:, English language papers published between January 1995 and February 2007 that examined compliance/persistence with medication for CVD or related conditions, provided an economic evaluation of pharmacological interventions or cost analysis, and quantified the cost consequences of noncompliance, were identified through database searches. The cost consequences of noncompliance were compared across studies descriptively. Results:, Of the 23 studies identified, 10 focused on hypertension, seven on diabetes, one on dyslipidaemia, one on coronary heart disease, one on heart failure and three covered multiple diseases. In studies assessing drug costs only, increased compliance/persistence led to increased drug costs. However, increased compliance/persistence increased the effectiveness of treatment, leading to a decrease in medical events and non-drug costs. This offset the higher drug costs, leading to savings in overall treatment costs. In studies evaluating the effect of compliance/persistence on the cost-effectiveness of pharmacological interventions, increased compliance/persistence appeared to reduce cost-effectiveness ratios, but the extent of this effect was not quantified. Conclusions:, Noncompliance with cardiovascular and antidiabetic medication is a significant problem. Increased compliance/persistence leads to increased drug costs, but these are offset by reduced non-drug costs, leading to overall cost savings. The effect of noncompliance on the cost-effectiveness of pharmacological interventions is inconclusive and further research is needed to resolve the issue. [source] Onset of Depression in Elderly Persons After Hip Fracture: Implications for Prevention and Early Intervention of Late-Life DepressionJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2007Eric J. Lenze MD OBJECTIVES: To identify predictors of onset of major depressive disorder (MDD) and of depressive symptoms in subjects who suffered a hip fracture. DESIGN: Prospective naturalistic study. SETTING: University of Pittsburgh Medical Center,Shadyside, a large urban hospital in Pittsburgh, Pennsylvannia. PARTICIPANTS: One hundred twenty-six elderly patients who received surgical fixation for hip fracture and who were not experiencing a major depressive episode at the time of the fracture; severely cognitively impaired persons were excluded. MEASUREMENTS: Subjects were evaluated at the time of hospital discharge using a battery of clinical measures (including apathy measured using the Apathy Evaluation Scale (AES), delirium, cognitive measures, social support, and disability level). Depression was assessed at the end of the surgical stay, 2 weeks later, and then monthly for 6 months, using the Hamilton Rating Scale for Depression (Ham-D) to evaluate symptomatology and the Primary Care Evaluation of Mental Disorders to evaluate diagnosis of MDD. RESULTS: Eighteen of 126 subjects (14.3%) developed MDD after hip fracture. Of these, 11 developed MDD by the end of the hospitalization, and seven developed MDD between 2 and 10 weeks later. Logistic regression showed that baseline apathy score, as measured using the AES, was the only clinical measure associated with the development of MDD (odds ratio=1.09, 95% confidence interval=1.03,1.16, P=.003); 46.2% of those with high AES scores developed MDD, versus 10.9% of those with lower scores. In contrast, cognitive variables, delirium, disability after hip fracture, and other factors related to the fracture (e.g., fracture type) were not associated with MDD. A repeated-measures analysis with Ham-D over time as a dependent variable generally confirmed these findings; depressive symptoms were highest immediately after the fracture, and apathy and delirium scores were associated with higher depressive symptom levels. CONCLUSION: The onset of MDD is common after hip fracture, and the greatest period of risk is immediately after the fracture. Individuals with clinical evidence of apathy are at high risk for developing MDD, and evaluation and close follow-up of such individuals is warranted. However, further research is needed to examine other candidate variables (e.g., clinical measures or biomarkers) to model adequately the risk for MDD after hip fracture and other disabling medical events. [source] Deaths Between Bedrails and Air Pressure MattressesJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2002Steven H. Miles MD OBJECTIVES: To describe how patients die by becoming trapped between therapeutic air pressure mattresses and bed rails. DESIGN: A retrospective review of all voluntary reports deaths in beds with air mattresses that can be found in the Food and Drug Administration's on-line databases of adverse medical events that cover 1994 to 2001. SETTING: Death reports come from manufacturers, medical staff, and coroners and describe deaths in hospitals, nursing homes, and home care, although type of care site is often not given. MEASUREMENTS: Event descriptions were reviewed to determine how the person became entrapped in the rail and how responsibility for the event was allocated. RESULTS: There were 35 deaths involving many product lines. Twenty-one deaths involved overlay air mattresses placed on top of a regular mattress. Thirteen patients died in beds with built-in air mattresses. Compression of the mattress allowed an off-center person to slide against the rail where reexpansion of the mattress kept the person compressed against the rail. Two patterns were seen. In one, the mattress bunched up behind a person who was lying on the side of the bed, pushing the neck against a bedrail. In the second type, a patient died after sliding off the bed and having the neck or chest compressed between the rail and bed. Manufacturers attributed the deaths to poor clinical decision-making or inadequate monitoring. CONCLUSIONS: Lethal asphyxiation in beds with air pressure mattresses is a variant of bedrail-mattress entrapment that requires redesign by bed manufacturers and risk awareness by clinicians. [source] Clinic in the Air?JOURNAL OF TRAVEL MEDICINE, Issue 6 2008A Retrospective Study of Medical Emergency Calls From A Major International Airline Background There is a high likelihood of a medical professional being onboard the aircraft at the time of emergency. Therefore, a health-care professional should be familiar with in-flight medical events and how to deal with them. Methods I present a 12-month retrospective study of medical distress calls from a major Asian international airline for which International SOS provided in-flight telemedical assistance. All the calls from the airplane to our center were analyzed from January 1, 2006, to January 1, 2007. The number of recommended diversions, availability of a medical professional, the range of medical problems, and used medications were considered. Results Overall, there were 191 in-flight air-to-ground consultations. Twenty-three (12.04%) calls were made for pediatric problems, with the youngest patient being 9 months old. Gastrointestinal complaints and simple faints comprised 50.2% of all calls. Most of the in-flight problems were successfully treated symptomatically with the initial recommendation to lie the patient down and administer oxygen. Metoclopramide, stemetil, loperamide, and buscopan were the most often administered drugs. A doctor was onboard in 45.5% of all calls. A recommendation to divert the aircraft was made in six (3.1%) cases. Conclusions Although developments in telemedical assistance and the content of a medical kit make the management of potential in-flight medical emergency much easier, they will never turn a commercial aircraft into a flying clinic. Preflight check-in screening by airlines and encouraging future air travelers with health concerns to seek medical help before flying should be recommended. [source] Long-Term Performance of Clarion 1.0 Cochlear Implant Users,THE LARYNGOSCOPE, Issue 7 2007Chad V. Ruffin BS Abstract Objective/Hypothesis: To evaluate the long-term performance of adult Clarion 1.0 cochlear implant users. Study Design: This was a retrospective, longitudinal study evaluating word discrimination in quiet for 31 adult cochlear implant patients with preimplantation sentence scores of less than 10%. Methods: The length of the study was 135 months with a mean follow-up length of 93 (median, 96) months. For the duration of the study, all subjects used the Clarion 1.0 cochlear implant with speech processors programmed for the use of the continuous interleaved sampling strategy. Results: There was no significant growth or decline in speech perception after 24 months postimplantation unless adverse medical events were experienced. Age at implantation was significantly and substantially negatively correlated (,11% word score per decade, r = 0.68) with most recent score, maximum score, time to maximum score, range of performance, 24- to 130-month mean score, and for any longitudinal data point tested: 3 to 6 months, 6 months, 1 year, 2 years, 5 years, and 10 years. There were no age-related declines in performance. There were no observed correlations between duration of deafness and any of the variables listed above. Conclusions: The lack of correlation between duration of deafness and performance in a cohort without residual hearing suggests the presence of a strong correlation between age and speech performance with a cochlear implant. That the cochlear implant is a safe therapy for the treatment of profound deafness is supported by the stability of scores through the 10-year study period as well as a zero rate of device failures or explantation. [source] Long-term efficacy and safety results of the two-stage implantation technique in sacral neuromodulationBJU INTERNATIONAL, Issue 9 2002W.A. Scheepens Objective ,To assess the long-term efficacy and safety of two-stage sacral neuromodulation with an implantable pulse generator (IPG) in patients treated for urinary urge incontinence (UI) and/or urinary retention (UR). Patients and methods ,The two-stage technique is used if patients have a good response during the acute phase of the percutaneous nerve evaluation (PNE) test, but have a poor response during the following 4,7 days (subchronic phase). In the first stage only the permanent electrode was implanted and connected to a temporary external stimulator, allowing patients to be assessed for longer. If the main symptoms improved by more than half the patient proceeded to the second stage, the insertion of the IPG. We reviewed all patients who underwent two-stage implantation; all had signed an informed consent and were asked to complete voiding diaries and a questionnaire to assess the subjective effects of the therapy. Safety was assessed from relevant medical events, management, and relative to the thera-py and resolution. Residual urine was assessed by self-catheterization. The long-term voiding diary results were compared with baseline estimates and analysed statistically using the two-sided Student's t -test. Results ,Between 1991 and 1998, 15 patients (13 women and two men, mean age 53 years, range 44,66) underwent the two-stage technique; the mean (median, range) follow-up was 4.9 (5.2, 2.5,7.5) years. Seven patients had UI and seven had UR, with one having both. The mean (range) number of PNEs undertaken in each patient was 2.1 (1,4) and these all failed in the subchronic phase. All patients underwent a first- and second-stage implant after a mean (range) screening period of 12.2 (2,29) days. One patient was explanted after implantation of only the first stage, and two others explanted in a later phase because the IPG was ineffective during the follow-up. The voiding diary results of the remaining 12 patients showed improvement in all the main variables, and in the subjective assessment 11 reported an improvement and were satisfied with the therapy. There were 17 adverse events, 14 of which were resolved and seven of which required surgical intervention. Conclusion ,The long-term results of the two-stage implantation show clinically and statistically significant improvements, probably because the implantation of the lead (first stage) more closely resembles the final therapy. If a temporary PNE test is not optimal (lead migration, longer testing needed), the two-stage technique can offer a good and safe alternative of comparable efficacy in the long-term. If the two-stage technique had not been available to these 12 patients they would not have been offered neuromodulation. [source] Twenty years of follow-up among survivors of childhood and young adult acute myeloid leukemia,CANCER, Issue 9 2008A report from the Childhood Cancer Survivor Study Abstract BACKGROUND Limited data exist on the comprehensive assessment of late medical and social effects experienced by survivors of childhood and young adult acute myeloid leukemia (AML). METHODS This analysis included 272 5-year AML survivors who participated in the Childhood Cancer Survivor Study (CCSS). All patients were diagnosed at age ,21 years between the years 1970 and 1986, and none underwent stem cell transplantation. Rates of survival, relapse, and late outcomes were analyzed. RESULTS The average follow-up was 20.5 years (range, 5,33 years). The overall survival rate was 97% at 10 years (95% confidence interval [95%CI], 94%,98%) and 94% at 20 years (95% CI, 90%,96%). Six survivors reported 8 recurrences. The cumulative incidence of recurrent AML was 6.6% at 10 years (95% CI, 3.7%,9.6%) and 8.6% at 20 years (95% CI, 5.1%,12.1%). Ten subsequent malignant neoplasms (SMN) were reported, including 4 with a history of radiation therapy, for a 20-year cumulative incidence of 1.7% (95% CI, 0.02%,3.4%). Six cardiac events were reported, for a 20-year cumulative incidence 4.7% (95% CI, 2.1%,7.3%). Half of the survivors reported a chronic medical condition and, compared with siblings, were at increased risk for severe or life-threatening chronic medical conditions (16% vs 5.8%; P < .001). Among those aged ,25 years, the age-adjusted marriage rates were similar among survivors and the general United States population (57% for both) and lower compared with siblings (67%; P < .01). Survivors' college graduation rates were lower compared with siblings but higher than the general population (40% vs 52% vs 34%, respectively; P < .01). Employment rates were similar between survivors, siblings, and the general population (93%, 97.6%, and 95.8%, respectively). CONCLUSIONS Long-term survival from childhood AML ,5-years after diagnosis was favorable. Late-occurring medical events remained a concern with socioeconomic achievement lower than expected within the individual family unit, although it was not different from the general United States population.
