Kinds of Care Population Selected AbstractsBreast Cancer Incidence in a Cohort of Women with Benign Breast Disease from a Multiethnic, Primary Health Care PopulationTHE BREAST JOURNAL, Issue 2 2007Maria J. Worsham PhD Abstract:, Women with benign breast diseases (BBD), particularly those with lesions classified as proliferative, have previously been reported to be at increased risk for subsequent development of breast cancer (BC). A cohort of 4970 women with biopsy-proven BBD, identified after histopathology review of BBD biopsies, was studied for determination of subsequent development of BC. We report on 4537 eligible women, 28% of whom are African-American, whose BBD mass was evaluable for pathologic assessment of breast tissue. Ascertainment of subsequent progression to BC from BBD was accomplished through examination of the tumor registries of the Henry Ford Health system, the Detroit SEER registry, and the State of Michigan cancer registry. Incidence rates (IR) are reported per 100,000 person years at risk (100 k pyr). Poisson regression models were used to evaluate the association of demographic and lesion characteristics with BC incidence, using person years at the time of BBD diagnosis as the offset variable. The estimated overall BC IR for this cohort is 452 (95% confidence interval [CI] = 394,519) per 100 k pyr. Incidence for women age 50 and older is 80% greater than for younger women (p = 0.007, IRR = 1.8, 95% CI = 1.36,2.36). Neither marital status (p = 0.91, IRR = 0.97, 95% CI = 0.73,1.29) nor race (p = 0.67, IRR = 0.9, 95% CI = 0.54,1.48) is associated with differences in BC IR. Compared with women having nonproliferative lesions, the risk for BC is greater for women with atypical ductal hyperplasia of (IRR = 5.0; 95%CI = 2.26,11.0; p < 0.001) and other proliferative lesions (IR = 1.7, 95% CI = 1.02,2.95; p = 0.04). BC risk for woman with atypical lesions is significantly higher than for women with proliferative lesions without atypia (IRR = 2.58, 95% CI = 1.35,4.90; p = 0.0039). Neither race nor marital status was a factor for BC incidence from BBD in this cohort. Age retained its importance as a predictor of risk. BBD lesion histopathology in the outcome categories of either proliferative without atypia or proliferative with atypia are significant risk factors for BC, even when adjusted for the influence of demographic characteristics. The risks associated with BBD histological classifications were not different across races. [source] How should peripheral neuropathy be assessed in people with diabetes in primary care?DIABETIC MEDICINE, Issue 5 2003A population-based comparison of four measures Abstract Aims To test the accuracy of four measures of peripheral diabetic neuropathy in a primary care population. Methods Type 2 diabetic (n = 544) and 544 non-diabetic participants aged 45,76 years were randomly selected from general practice registers. Neuropathy was assessed using vibration threshold (VT) and scores for light touch, thermal sense and modified Michigan Neuropathy Screening Instrument questionnaire. These measures were assessed for variation with diabetes status, age, diabetes duration, HbA1c, and presence of retinopathy and nephropathy. Light touch, thermal sense and questionnaire scores were assessed against VT using ROC curve analysis. Results Only VT and light touch were different between diabetic and non-diabetic groups (P = 0.02 and < 0.0001, respectively). All measures were significantly associated with diabetes duration and retinopathy, and all except questionnaire score (P = 0.14) with age. None was associated with nephropathy and only questionnaire score was associated with HbA1c (P = 0.033). VT varied as expected across scores of light touch (,2 = 41.65, P = 0.0001), thermal sense (,2 = 15.86, P = 0.015) and questionnaire (,2 = 21.22, P = 0.047). Area under the curve values for light touch, thermal and questionnaire scores were 0.72 (95% confidence interval (CI) 0.63, 0.82), 0.63 (95% CI 0.52, 0.73) and 0.64 (95% CI 0.53, 0.74), respectively. Conclusions All measures had associations with risk factors for neuropathy, but light touch score (monofilament) had the strongest association with vibration threshold (the chosen gold standard) and thus appeared the most appropriate tool for use in primary care, because of its validity and simplicity of use. Diabet. Med. 20, 368,374 (2003) [source] Prevalence and cost of nonadherence with antiepileptic drugs in an adult managed care populationEPILEPSIA, Issue 3 2008Keith L. Davis Summary Purpose: This study assessed the extent of refill nonadherence with antiepileptic drugs (AEDs) and the potential association between AED nonadherence and health care costs in an adult-managed care population. Methods: Retrospective claims from the PharMetrics database were analyzed. Inclusion criteria were: age ,21, epilepsy diagnosis between January 01, 2000 and March 12, 2005, ,2 AED prescriptions, and continuous health plan enrollment for ,6 months prior to and ,12 months following AED initiation. Adherence was evaluated using the medication possession ratio (MPR). Patients with an MPR <0.8 were classified as nonadherent. Multivariate regression was used to assess the effect of AED nonadherence on annualized cost outcomes. Regression covariates included patient demographics, Charlson Comorbidity Index (CCI), and follow-up duration. Results: Among patients meeting all inclusion criteria (N = 10,892), 58% were female, mean age was 44 years, mean CCI was 0.94, and mean follow-up was 27 months. Mean MPR was 0.78 and 39% of patients were nonadherent. AED nonadherence was associated with an increased likelihood of hospitalization (odds ratio [OR]= 1.110, p = 0.013) and emergency room (ER) admission (OR = 1.479, p < 0.0001), as well as increased inpatient and ER costs of $1,799 and $260 (both p = 0.001), respectively, per patient per year. Outpatient and other ancillary costs were not significantly affected by nonadherence. A large net positive effect of nonadherence on total annual health care costs remained (+$1,466, p = 0.034) despite an offset from reduced prescription drug intake. Discussion: Adherence with AEDs among adult epilepsy patients is suboptimal and nonadherence appears to be associated with increased health care costs. Efforts to promote AED adherence may lead to cost savings for managed care systems. [source] Patient reporting and doctor recognition of dyspnoea in a comprehensive cancer centreINTERNAL MEDICINE JOURNAL, Issue 6 2006A. W. Hayes Abstract The aim of this study was to examine different aspects of dyspnoea in an Australian acute cancer care population, specifically prevalence, recognition, reporting, symptom control methods and prognostic significance. Patients and treating hospital medical officer were concurrently asked to evaluate the experience of dyspnoea. The prevalence of dyspnoea was 33%, with discrepancies observed between patient and doctor reporting of the presence of dyspnoea (P = 0.021), as well as its intensity and distress. Symptomatic methods for the relief of cancer-related dyspnoea are underused, particularly opioids. The medical underestimation of dyspnoea is consistent with previous studies and potentially detracts from effective management of this symptom. [source] Prevalence of abdominal obesity in primary care: the IDEA UK studyINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 9 2009J. Morrell Summary Background:, Abdominal obesity is known to be a risk factor for cardiovascular and metabolic diseases. However, despite the importance of abdominal obesity as a risk factor for cardiovascular and metabolic disease, there are currently no UK-specific data on its prevalence in patients attending primary care. Aim:, The aim of the International Day for the Evaluation of Abdominal obesity (IDEA)-UK observational study was to determine the distribution of waist circumference , a marker of abdominal obesity , and its relationship with cardiovascular risk markers in a UK-based primary care population. Methods:, Patients underwent measurements of height, weight and waist circumference and provided data on reported cardiovascular disease (CVD), diabetes, hypertension and dyslipidaemia. Results:, A total of 1731 patients were assessed within the study, of which 719 were male and 1012 were female. Of these 1731 patients, 1718 had complete datasets for the presence of reported cardiovascular risk factors. Median waist circumference in the male and female populations respectively was 99.0 cm [interquartile range (IQR) 91.0,108.0 cm] and 89.0 cm (IQR 79.0,100 cm). In all, 38.8% of men and 51.2% of women were abdominally obese (waist circumference > 102 cm and > 88 cm respectively) according to the US National Cholesterol Education Program (NCEP) guidelines. Within both male and female populations, the incidence of reported CVD, lipid disorders, hypertension and diabetes increased with increasing quartiles for waist circumference. Conclusion:, Increased waist circumference is widespread in patients attending primary care in the UK and is associated with elevated levels of reported diabetes, hypertension, lipid disorders and CVD. [source] Is there an association between referral population deprivation and antibiotic prescribing in primary and secondary care?INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 4 2008Christopher Curtis head of pharmaceutical services Objective The study was designed to explore the presence of any relationship between NHS secondary care antibiotic prescribing rates or primary care antibiotic prescribing rates and the levels of deprivation experienced within the referred primary care population. The study also aimed to determine whether the antibiotic prescribing rates for each care sector were correlated. Method The study was conducted in 12 English hospital trusts of mixed size and case-mix. Antibiotic usage data (Anatomical Therapeutic Chemical (ATC) category J01) for the financial year, ending March 2001/2002 were used to calculate hospital trust prescribing rates (using the defined daily dose/finished consultant episode indicator). Primary care antibiotic prescribing data were obtained from the Prescription Pricing Authority (antibiotic items prescribed per 1000 residents) for the year 2001/2002. Index of Multiple Deprivation (IMD) 2000 deprivation data were obtained from the regional public health observatory websites for each of the primary care trusts within the relevant study areas. Key findings No correlation could be established between the weighted index of multiple deprivation of the treated population and antibiotic prescribing rates at each hospital trust. Primary care antibiotic prescribing rates were not found to correlate with antibiotic prescribing rates in the geographically associated hospital trust. Data from all 12 sites showed that the IMD 2000 measures and primary care prescribing rates were weakly correlated, with higher antibiotic prescribing rates being generally observed in areas of primary care exhibiting the worst levels of deprivation Conclusions The likely explanations for the present findings are that deprivation-related illnesses are principally treated within primary care, whereas hospital antibiotic prescribing principally results from procedures isolated within secondary care or through the additional influence of nosocomial infection. Therefore, medicines management measures geared to controlling antibiotic prescribing in secondary care should not focus upon the levels of deprivation in the referred population, whereas those in primary care should.

(2010) Psycho-social Factors Affecting Elders' Maltreatment in Long-term Care Facilities. International Nursing Review57, 113,120 Aim:, To examine and analyse major variables affecting maltreatment of elderly nursing home residents. The study was based on two theoretical paradigms: the theoretical model for predicting causes of maltreatment of elderly residents developed by Pillemer, and the Theory of Reasoned Action developed by Ajzen & Fishbein. Methods:, The study employed a correlational quantitative method. The research population consisted of the staff of 22 nursing homes in Israel. Six hundred questionnaires were distributed in these facilities and 510 were completed and returned (85%). In addition, 24 questionnaires were distributed among directors of the facilities and 22 were returned (91.6%). Findings:, Slightly more than half of the staff sampled reported abuse of elderly residents over the past year, as manifested in one or more of types of maltreatment. The total number of various types of maltreatment reported was 513. About two-thirds of the cases were incidents of neglect. Seventy per cent of respondents reported that they had been present at incidents in which another staff member abused an elderly resident in one or more types of maltreatment, and in such situations mental abuse and mental neglect were the most prevalent forms of maltreatment. Conclusion and Recommendations:, This is the first study to examine elder maltreatment in the long-term care population of Israel. The research findings produce an expanded and improved research model investigating elder maltreatment in long-term nursing homes. [source] Is physician-diagnosed allergic rhinitis a risk factor for the development of asthma?ALLERGY, Issue 8 2010L. Van Den Nieuwenhof To cite this article: van den Nieuwenhof L, Schermer T, Bosch Y, Bousquet J, Heijdra Y, Bor H, van den Bosch W, van Weel C. Is physician-diagnosed allergic rhinitis a risk factor for the development of asthma? Allergy 2010; 65: 1049,1055. Abstract Background:, There is strong evidence that there is a relationship between allergic rhinitis (AR) and asthma, but it is unclear whether there is a causal relation between AR and asthma. The aim of this study was to assess prospectively whether AR is a risk factor for the diagnosis of asthma in a large primary care population. Methods:, We performed a historic cohort study of life-time morbidity that had been recorded prospectively since 1967 in four general practices. Two groups of subjects were selected: (i) patients with diagnosis of AR, (ii) a control group matched using propensity scores. We assessed the risk of physician-diagnosed asthma in patients with physician-diagnosed AR compared to subjects without a diagnosis of AR (controls). Results:, The study population consisted of 6491 subjects (n = 2081 patients with AR). Average study follow-up was 8.4 years. In patients with AR, the frequency of newly diagnosed asthma was 7.6% (n = 158) compared to 1.6% (n = 70) in controls (P < 0.001). After adjusting the effect of AR on asthma diagnosis for registration time, age, gender, eczema and socioeconomic status, having AR was a statistically significant risk factor for asthma (hazard ratio: 4.86, P < 0.001, 95% confidence interval: 3.50,6.73, controls as reference). Conclusion:, A diagnosis of AR was an independent risk factor for asthma in our primary care study population. Having physician-diagnosed AR increased the risk almost fivefold for a future asthma diagnosis. [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] Measuring psychological morbidity for diabetes commissioningPRACTICAL DIABETES INTERNATIONAL (INCORPORATING CARDIABETES), Issue 1 2010A cross-sectional survey of patients attending a secondary care diabetes clinic Abstract The aim of this study was to investigate the prevalence of psychological morbidity in the local secondary care population of people with type 1 diabetes or type 2 diabetes (T1DM or T2DM) in order to determine appropriate treatment provision. Four hundred patients seen in diabetes outpatient clinics were sent a number of standardised and validated questionnaires designed to measure: diabetes related distress; anxiety and depression; disordered eating behaviours; and borderline personality disorder. A response rate of 52.7% was achieved, providing a total of 211 completed questionnaires (111 T1DM, 100 T2DM) for analysis. This study has demonstrated a high prevalence of psychological morbidity in the local secondary care population of people with diabetes, with as many as half of those surveyed (52%) reporting some level of psychological disturbance. After controlling for age, gender and diabetes type, few differences in levels of psychological dysfunction were identified between the T1DM and T2DM cohorts. The exception to this was disinhibited eating behaviours: 22% of people with T2DM had severe levels of disinhibited eating, twice that recorded in the T1DM population. Overall, 36% (n=76) of study participants had moderate,severe levels of depression, anxiety or both, and 9.5% (16 of 168) had scores suggestive of borderline personality disorder.

Henning MD ABSTRACT:,Purpose:The purpose of this pilot study was to determine the reasons for which migrant agricultural workers in Pennsylvania seek health care.Methods:Participants were individuals 14 years of age and over, actively involved in agricultural labor and presenting for medical care at 6 migrant health care centers. Bilingual health care providers randomly selected and interviewed the participants.Findings:The most commonly reported reason for visiting the health care provider was for physical examination. The most frequent acute problems were related to the musculoskeletal and integumentary systems. Frequently cited problems in the medical history were hypertension, musculoskeletal/back pain, and gastrointestinal conditions. Most medications being taken were for cardiovascular or pain-related problems.Conclusions:These results suggest that migrant workers present with medical problems that are similar to those of the general primary care population. Many problems were recurrent and represented common chronic medical conditions. [source] Resistant Pathogens in Urinary Tract InfectionsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2002Lindsay E. Nicolle MD Antimicrobial susceptibility of bacteria causing urinary tract infection (UTI) has evolved over several decades as antimicrobial exposure has repeatedly been followed by emergence of resistance. Older populations in the community, long-term care facilities, or acute care facilities have an increased prevalence of resistant bacteria isolated from UTI. Resistant isolates are more frequent in long-term care populations than the community. Resistant isolates include common uropathogens, such as Escherichia coli or Proteus mirabilis, and organisms with higher levels of intrinsic resistance, such as Pseudomonas aeruginosa or Providencia stuartii. Isolation of resistant organisms is consistently associated with prior antimicrobial exposure and higher functional impairment. The increased likelihood of resistant bacteria makes it essential that a urine specimen for culture and susceptibility testing be obtained before instituting antimicrobial therapy. Therapy for the individual patient must be balanced with the possibility that antimicrobial use will promote further resistance. Antimicrobial therapy should be avoided unless there is a clear clinical indication. In particular, asymptomatic bacteriuria should not be treated with antimicrobials. Where symptoms are mild or equivocal, urine culture results should be obtained before initiating therapy. This permits selection of specific therapy for the infecting organism and avoids empiric, usually broad-spectrum, therapy. Where empirical therapy is necessary, prior infecting organisms should be isolated, and recent antimicrobial therapy, as well as regional or facility susceptibility patterns, should be considered in antimicrobial choice. Where empirical therapy is used, it should be reassessed 48 to 72 hours after initiation, once pretherapy cultures are available. [source] Systematic review: accuracy of symptom-based criteria for diagnosis of irritable bowel syndrome in primary careALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 7 2009P. JELLEMA Summary Background, Despite the trend towards making a positive diagnosis of irritable bowel syndrome (IBS), many health care providers approach IBS as a diagnosis of exclusion. Aim, To summarize available evidence on the diagnostic performance of symptom-based IBS criteria in excluding organic diseases, and of individual signs and symptoms in diagnosing IBS and to additionally assess the influence of sources of heterogeneity on diagnostic performance. Methods, We searched PubMed and EMBASE and screened references. Studies were selected if the design was a primary diagnostic study; the patients were adults consulting because of non-acute abdominal symptoms; the diagnostic test included an externally validated set of IBS criteria, signs, or symptoms. Data extraction and quality assessment were performed by two reviewers independently. The review adhered to the most recent guidelines as described in the Cochrane Diagnostic Reviewers' Handbook. Results, A total of 25 primary diagnostic studies were included in the review. The performance of symptom-based criteria in the exclusion of organic disease was highly variable. Patients fulfilling IBS criteria had, however, a lower risk of organic diseases than those not fulfilling the criteria. Conclusions, With none of the criteria showing sufficiently homogeneous and favourable results, organic disease cannot be accurately excluded by symptom-based IBS criteria alone. However, the low pre-test probability of organic disease especially among patients who meet symptom-based criteria in primary care argues against exhaustive diagnostic evaluation. We advise validation of the new Rome III criteria in primary care populations. [source] An evaluation of the psychometric properties of the traumatic events questionnaire in primary care patientsJOURNAL OF TRAUMATIC STRESS, Issue 1 2008Eric F. Crawford This study examined the reliability of reports of traumatic experiences across the Traumatic Events Questionnaire (TEQ; S. Vrana & D. Lauterbach, 1994) and the Composite International Diagnostic Interview (CIDI; World Health Organization, 1998), and evaluated other psychometric properties of the TEQ in 154 primary care patients. Agreement rates for various traumatic experiences were moderate to substantial, with sexual abuse showing 87% agreement, and other forms of trauma exhibiting rates from 81,74%. The TEQ yields a trauma intensity score, which produced stronger correlations with self-reported PTSD symptoms and problematic anger than the sum of traumas experienced. Trauma intensity also proved to be a powerful predictor of posttraumatic stress disorder (PTSD) diagnostic status. Results support the TEQ as a measure of traumatic exposure in primary care populations. [source] | |||||||||||||||||||
