Routine diagnostic procedures for chronic encephalopathy induced by solvents: survey of experts.
(57/1071)
OBJECTIVES: To study the routine diagnostic procedures used in different countries for chronic toxic encephalopathy (CTE) induced by solvents. METHODS: By means of a postal questionnaire selected international experts were asked about the methods they use to diagnose patients suspected of having CTE induced by solvents, the number of patients, entrance criteria, and the results of these diagnostic procedures. RESULTS: 18 Experts working in 18 diagnostic centres responded. Most of them agreed that a diagnostic procedure for CTE induced by solvents should contain an interview and neurological, physical, and neuropsychological examinations. However, the tests used were very different, as were the classifications for CTE. Depending on the institute, a diagnosis of CTE was made in 6%--70% of the referred patients. The proportion of patients with CTE stage I ranged from 0% to 33%, stage II from 5% to 100%, and stage III from 0% to 95%. CONCLUSION: The intentions of the two 1985 conferences that aimed at clarity and uniformity of diagnosis of CTE induced by solvents are far from reached. It is possible, now the conditions are more favourable, to aim at this important goal and recommend some refinement of the then proposed criteria. (+info)
Deprivation, psychological distress, and consultation length in general practice.
(58/1071)
BACKGROUND: Recent research has shown the benefits of longer consultations in general practice. Approximately 40% of patients presenting to general practitioners (GPs) are psychologically distressed. Studies have shown that psychological morbidity increases with increasing socioeconomic deprivation. The combined effects of psychological morbidity and socioeconomic deprivation on consultation length are unknown. In addition, though it is known that doctors correctly identify half their distressed patients as such, the effect of consultation length on identification is unknown. AIM: To examine factors associated with presentation and recognition of psychological distress in GPs' surgeries and the interaction of these factors with consultation length. DESIGN OF STUDY: A cross-sectional study. SETTING: Nine general practices in the West of Scotland, involving 1075 consultations of 21 full-time GPs. METHOD: The main outcome measures were patient psychological distress (measured by General Health Questionnaire-12), doctors' identification of psychological distress, consultation length, and Carstairs deprivation category scores. RESULTS: The mean consultation length was 8.71 minutes (SD = 4.40) and the prevalence of positive GHQ scores was 44.7%. Increasing GHQ (greater psychological distress) and lower deprivation category scores (greater affluence) were associated with longer consultations. Positive GHQ scoring increased with greater socioeconomic deprivation and also peaked in the 30 to 39 years age group. Recognition of psychological distress was greater in longer consultations (50% increase in consultation length associated with 32% increase in recognition). CONCLUSION: Increasing socioeconomic deprivation is associated with higher prevalence of psychological distress and shorter consultations. This provides further evidence to support Tudor Hart's 'inverse care law' and has implications for the resourcing of primary care in deprived areas. (+info)
Women who experience domestic violence and women survivors of childhood sexual abuse: a survey of health professionals' attitudes and clinical practice.
(59/1071)
Health professionals do not wish to routinely screen women for a history of domestic violence or childhood sexual abuse. However, over 80% believe that these are significant health care issues. Routine screening should not be prioritised until evidence of benefit has been established. (+info)
Applicability of diagnostic recommendations on dementia in family practice.
(60/1071)
OBJECTIVE: To evaluate the applicability of the Dutch dementia guideline's recommendations, including the diagnostic criteria used by family practitioners, and to explore characteristics in both patients and family practitioners which are associated with the use of these recommendations. DESIGN: An observational study was set up with a sample of 64 family practitioners who were instructed to use the Dutch national dementia guideline on incident-suspected dementia patients. The applicability was expressed as the percentage of recommendations applied. The use of diagnostic criteria was checked by comparing the family practitioners diagnoses with the diagnoses received by integrating the registered symptoms according to the DSM-III-R criteria. Associations between the number of recommendations applied, and demographic and clinical features were explored. MAIN OUTCOME MEASURES: (i) guideline applicability (ii) integrated use of DSM-III-R criteria. RESULTS: 107 patients were included. The average application rate of the guideline's 31 diagnostic key recommendations was 86% or 24.8 (SD 3.6). The family practitioners diagnoses were consistent with the expected DSM-III-R diagnoses in 26% of the cases (kappa = 0.1). A greater number of patients in a practice was positively associated with the use of recommendations. A need for referral by the family practitioners, and patients' denial of dementia were negatively associated with the use of recommendations. The presence of dementia and a patient's age were negatively associated with the use of the DSM-III-R criteria. CONCLUSIONS: The applicability of the diagnostic recommendations of the national Dutch dementia guideline in a representative sample of family practitioners was promising. Nevertheless, the diagnostic criteria of the DSM-III-R, which were part of the dementia guideline, provided little or no guidance to the family practitioners in their diagnostic decision-making. Clinical and demographic variables explained some of the variation in the use of recommendations. (+info)
Participation of epidemiologists and/or biostatisticians and methodological quality of published controlled clinical trials.
(61/1071)
STUDY OBJECTIVE: This study assessed several methodological aspects related to the quality of published controlled clinical trials (CCTs) in relation to the participation of an epidemiologist/biostatistician (E/B). DESIGN: Handsearch of CCTs published in four medical leading journals for 1993-1995. METHODS: Quality variables, abstracted from a review, were related to authors' specialties. Five hundred and ninety four CCTs were identified via a hand search. The department/unit membership was used to attribute authors' specialties. Of 594 CCTs identified, in 127 the authors' specialties could not be known, leaving 467 trials for analysis. RESULTS: E/B participation occurred in 178 trials (38.1%). This participation was more frequent in multicentric, bigger, and in those trials describing any funding agency. These factors were controlled for in the analysis. E/B participation was positively associated with pre-study sample size estimation (OR = 1.5, 95% confidence intervals (CI) 1.0, 2.3), with reporting the dates for starting/ending the study (OR = 2.1, 95% CI 1.4, 3.3), with using an objectively assessed outcome (OR = 2.4, 95% CI 1.2, 4.6) and with the intention to treat principle (OR = 2.0, 95% CI 1.3, 3.0). The overall quality score was higher in trials where E/B participated. CONCLUSIONS: The results suggest that E/B improve the quality (at least of reports) of clinical trials. Given that quality of research is frequently used to evaluate potential sources of heterogeneity between trials, these results are relevant for meta-analysis. (+info)
Primary care physician job satisfaction and turnover.
(62/1071)
OBJECTIVE: To examine the relationship of personal characteristics, organizational characteristics, and overall job satisfaction to primary care physician (PCP) turnover. SUBJECTS AND METHODS: A cohort of 507 postresident, nonfederally employed PCPs younger than 45 years of age, who completed their medical training between 1982 and 1985, participated in national surveys in 1987 and 1991. Psychological, economic, and sociological theories and constructs provided a conceptual framework. Primary care physician personal, organizational, and overall job satisfaction variables from 1987 were considered independent variables. Turnover-related responses from 1991 were dependent variables. Bivariate and multivariate analyses were conducted. RESULTS: More than half (55%) of all PCPs in the cohort left at least 1 practice between 1987 and 1991. Twenty percent of the cohort left 2 employers. PCPs dissatisfied in 1987 were 2.38 times more likely to leave (P < .001). Primary care physicians who believed that third-party payer influence would decrease in 5 years were 1.29 times more likely to leave (P < .03). Non-board certified PCPs were 1.3 times more likely to leave (P < .003). Primary care physicians who believed that standardized protocols were overused were 1.18 times more likely to leave (P < .05). Specialty, gender, age, race, and practice setting were not associated with PCP turnover. CONCLUSIONS: Turnover was an important phenomenon among PCPs in this cohort. The results of this study could enable policy makers, managed care organizations, researchers, and others to better understand the relationship between job satisfaction and turnover. (+info)
Touch contamination levels during anaesthetic procedures and their relationship to hand hygiene procedures: a clinical audit.
(63/1071)
After different methods of hand preparation, volunteers rolled segments of sterile central venous catheter between their fingertips, and bacterial transfer was evaluated by standardized quantitative culture. The number of bacteria transferred differed between methods (P<0.001). Comparisons were made with the control group (no preparation at all; median, third quartile and maximum count=6.5, 24, 55). Bacterial transfer was greatly increased with wet hands (1227, 1932, 3254; P<0.001). It was reduced with a new rapid method, based on thorough drying with a combination of 10 s using a cloth towel followed by either 10 or 20 s with a hot-air towel (0, 3, 7 and 0, 4, 30, respectively; P=0.007 and 0.004, respectively). When asked to follow their personal routines, 10 consultant anaesthetists used a range of methods. Collectively, these were not significantly better than control (7.5, 15, 55; P=0.73), and neither was an air towel alone (2.5, 15, 80; P=0.176) nor the hospital's standard procedure (0, 1, 500; P=0.035). If hand preparation is needed, an adequate and validated method should be used, together with thorough hand drying. (+info)
Physicians certified in family medicine. What are they doing 8 to 10 years later?
(64/1071)
OBJECTIVE: To determine field of medicine and location of a cohort of physicians certified in family medicine between 1989 and 1991 and residing in Ontario in 1993 and to gather information on the scope of practice of family physicians in the cohort in 1999. DESIGN: Responses to a mailed questionnaire sent in 1999 were compared with responses to a 1993 survey of this group. SETTING AND PARTICIPANTS: All family physicians in Ontario in 1993 who received certification in 1989, 1990, or 1991 after completing a family medicine residency. Seven of 557 respondents to the 1993 survey were ineligible; 293 physicians (53%) responded to the 1999 survey. MAIN OUTCOME MEASURES: Field, location, and scope of practice. RESULTS: About 91% of the cohort were still practising family medicine, although 11% of these had restricted their practices to certain areas within family medicine. Physicians migrated from Ontario (6%) in nearly equal numbers to other provinces and other countries, predominantly the United States. More family physicians offered counseling, shared antenatal care, and newborn care in 1999 than in 1993. Those with restricted family practices provided fewer types of services and were less likely to provide antenatal or intrapartum care or to provide in-hospital services. CONCLUSION: Receiving certification in family medicine does not guarantee that physicians will remain in family practice 8 to 10 years later. Loss from general family medicine to restricted practices within family medicine and specialization was greater than loss from migration. (+info)
