The relationship between operator volume and outcomes after percutaneous coronary interventions in high volume hospitals in 1994-1996: the northern New England experience. Northern New England Cardiovascular Disease Study Group.
(57/5672)
OBJECTIVES: The purpose of this study was to examine the relationship between annual operator volume and outcomes of percutaneous coronary interventions (PCIs) using contemporaneous data. BACKGROUND: The 1997 American College of Cardiology (ACC)/American Heart Association task force based their recommendation that interventionists perform > or = 75 procedures per year to maintain competency in PCI on data collected largely in the early 1990s. The practice of interventional cardiology has since changed with the availability of new devices and drugs. METHODS: Data were collected from 1994 through 1996 on 15,080 PCIs performed during 14,498 hospitalizations by 47 interventional cardiologists practicing at the five high volume (>600 procedures per hospital per year) hospitals in northern New England and one Massachusetts-based institution that support these procedures. Operators were categorized into terciles based on their annualized volume of procedures. Multivariate regression analysis was used to control for case-mix. In-hospital outcomes included death, emergency coronary artery bypass graft surgery (eCABG), non-emergency CABG (non-eCABG), myocardial infarction (MI), death and clinical success (> or = 1 attempted lesion dilated to < 50% residual stenosis and no death, CABG or MI). RESULTS: Average annual procedure rates varied across terciles from low = 68, middle = 115 and high = 209. After adjusting for case-mix, clinical success rates were comparable across terciles (low, middle and high terciles: 90.9%, 88.8% and 90.7%, Ptrend = 0.237), as were all the adverse outcomes including death (low-risk patients = 0.45%, 0.41%, 0.71%, Ptrend = 0.086; high-risk patients = 5.68%, 5.99%, 7.23%, Ptrend = 0.324), eCABG (1.74%, 2.05%, 1.75%, Ptrend = 0.733) and MI (2.57%, 1.90%, 1.86%, Ptrend = 0.065). CONCLUSIONS: Using current data, there is no significant relationship between operator volumes averaging > or = 68 per year and outcomes at high volume hospitals. Future efforts should be directed at determining the generalizability of these results. (+info)
Can small group education and peer review improve care for patients with asthma/chronic obstructive pulmonary disease?
(58/5672)
OBJECTIVE: To study the effectiveness of an intensive small group education and peer review programme aimed at implementing national guidelines on asthma/chronic obstructive pulmonary disease (COPD) on care provision by general practitioners (GPs) and on patient outcomes. DESIGN: A randomised experimental study with pre-measurement and post-measurement (after one year) in an experimental group and a control group in Dutch general practice. SUBJECTS AND INTERVENTION: Two groups of GPs were formed and randomised. The education and peer review group (17 GPs with 210 patients) had an intervention consisting of an interactive group education and peer review programme (four sessions each lasting two hours). The control group consisted of 17 GPs with 223 patients (no intervention). MAIN OUTCOME MEASURES: Knowledge, skills, opinion about asthma and COPD care, presence of equipment in practice; actual performance about peakflow measurement, non-pharmacological and pharmacological treatment; asthma symptoms (Dutch Medical Research Council), smoking habits, exacerbation ratio, and disease specific quality of life (QOL-RIQ). Data were collected by a written questionnaire for GPs, by self recording of consultations by GPs, and by a written self administered questionnaire for adult patients with asthma/COPD. RESULTS: Data from 34 GP questionnaires, 433 patient questionnaires, and recordings from 934 consultations/visits and 350 repeat prescriptions were available. Compared with the control group there were only significant changes for self estimated skills (+16%, 95% confidence interval 4% to 26%) and presence of peakflow meters in practice (+18%, p < 0.05). No significant changes were found for provided care and patient outcomes compared with the control group. In the subgroup of more severe patients, the group of older patients, and in the group of patients not using anti-inflammatory medication at baseline, no significant changes compared with the control group were seen in patient outcomes. CONCLUSION: Except for two aspects, intensive small group education and peer review in asthma and COPD care do not seem to be effective in changing relevant aspects of the provided care by GPs in accordance with guidelines, nor in changing patients' health status.

The impact of training in problem-based interviewing on the detection and management of psychological problems presenting in primary care.
(59/5672)
BACKGROUND: The vast majority of mental health problems present to primary care teams. However, rates of under-diagnosis remain worryingly high. This study explores a GP-centred approach to these issues. AIM: To examine the impact of training in problem-based interviewing (BPI) on the detection and management of psychological problems in primary care. METHOD: The detection and management of psychological problems by 10 general practitioners (GPs) who had received PBI training 12 months earlier was compared with that of 10 control GPs matched for age, sex, clinical experience, and practice setting; and had originally applied for, but had not been able to attend, BPI training. Consecutive attendees at one randomly selected surgery undertaken by each GP were invited to participate in the study. Two hundred and eighty patients living in Newcastle upon Tyne met inclusion criteria and gave informed consent. The presence or absence of psychological problems was assessed using patient self-ratings on the 28-item version of the General Health Questionnaire (GHQ) and blind independent observer ratings of the brief Present State Examination (PSE). Patient satisfaction with interviews was rated using the Medical Interview Satisfaction Scale (MISS). After each consultation, the GPs (blind to subjective and observer ratings) recorded their assessment and management of the patients' problems on a Practice Activity Card (PAC). RESULTS: In comparison with control GPs, index GPs demonstrated significantly greater sensitivity in the detection of psychological problems in the GHQ-PAC ratings. The absolute decrease in misdiagnosis of GHQ cases was 9% and of PSE cases was 15%. Patients meeting GHQ criteria for caseness were more likely to be prescribed psychotropic medication by an index GP than compared with a control GP. Length of interview did not differ between the groups and mean scores on the MISS suggested that patients attending PBI-trained GPs, compared with control GPs, were as satisfied or slightly more satisfied with their consultation. CONCLUSION: In comparison with control GPs, PBI-trained GPs were better at recognizing and managing psychological disorders. The potential benefits of BPI training are discussed in light of other attempts to improve mental health skills in primary care. (+info)
Clinical skills assessment.
(60/5672)
BACKGROUND: From September 1996, all GP registrars completing vocational training in the United Kingdom must demonstrate competence by means of a four-part assessment procedure. AIM: To look at the accuracy of one of the components of vocational training: the trainer's report. METHOD: Seventy-five registrars completing their general practice training at the end of July 1997 were invited to take part in a practical skills workshop. Eight stations were designed to test practical skills and diagnostic interpretations that were included in the trainer's report, and a clinical vignette accompanied each task. The marking schedule used was developed from the minimum standards required in the trainer's report. Twenty-nine registrars (38%) took part in the workshop. RESULTS: Only one registrar passed all eight stations. The maximum number of stations failed by any one individual was five and this doctor was the only one of the sample to ultimately fail summative assessment. The majority of registrars failed by being unable to interpret clinical findings. Twenty-five registrars (86%) responded to the follow-up questionnaire. Of these, only six felt that the stations were unrealistic. All but two registrars had spent at least six months in their hospital training doing obstetrics and gynaecology but, in spite of this, only 31% of registrars were above minimum competence for vaginal and speculum examination. CONCLUSION: With one exception, registrars passed all aspects of the trainer's report. Discrepancy was found between the trainer's report and the doctor's ability to carry out clinical procedures. There is an assumption that many of these clinical skills are being taught and assessed at undergraduate level and during the hospital component, but this cannot be taken for granted. Doubt must also be cast on whether the trainers are using the trainer's report appropriately, and whether this is a valid and reliable tool to identify skills deficient in registrars for summative assessment.

Doctors and the assessment of clinical photographs--does colour blindness matter?
(61/5672)
Colour vision deficiency (CVD) is a common anomaly, especially in the male population. A group of doctors with CVD was compared with a control group. Doctors with CVD differed from controls in respect of their ability to detect, and in their confidence in the assessment of, abnormalities presented in clinical photographs. These findings suggest that doctors with CVD should take special care to ensure safe clinical practice. (+info)
Colour vision deficiency in the medical profession.
(62/5672)
Colour is often used as a sign in medicine, yet there have been few studies into the effects of a colour vision deficiency (CVD) on doctors' medical skills. Using a literature search, the results indicate the prevalence of CVD in the medical profession and its effects on medical skills. For the congenital form among male doctors in the United Kingdom, the prevalence is shown to be probably about the same as for the population at large; i.e. 8%. However, the data is insufficient for any estimate to be made of the small number of female doctors and for the acquired forms of CVD. The effect on skills is also shown. Because of certain features of their work, general practitioners may have special problems. Thus, it is concluded that medical students and doctors should be screened for the deficiency and advised about it, and that there should be more study of the effects of CVD on decision-making in general practice and some specialties.

Student and faculty performance in clinical simulations with access to a searchable information resource.
(63/5672)
In this study we explore how students' use of an easily accessible and searchable database affects their performance in clinical simulations. We do this by comparing performance of students with and without database access and compare these to a sample of faculty members. The literature supports the fact that interactive information resources can augment a clinician's problem solving ability in small clinical vignettes. We have taken the INQUIRER bacteriological database, containing detailed information on 63 medically important bacteria in 33 structured fields, and incorporated it into a computer-based clinical simulation. Subjects worked through the case-based clinical simulations with some having access to the INQUIRER information resource. Performance metrics were based on correct determination of the etiologic agent in the simulation and crosstabulated with student access of the information resource; more specifically it was determined whether the student displayed the database record describing the etiologic agent. Chi-square tests show statistical significance for this relationship (chi 2 = 3.922; p = 0.048). Results support the idea that students with database access in a clinical simulation environment can perform at a higher level than their counterparts who lack access to such information, reflecting favorably on the use of information resources in training environments.

Evaluation of guidelines for emergency triage assessment and treatment in developing countries.
(64/5672)
AIM: To evaluate performance of a simplified algorithm and treatment instructions for emergency triage assessment and treatment (ETAT) of children presenting to hospital in developing countries. METHODS: All infants aged 7 days to 5 years presenting to an accident and emergency department were simultaneously triaged and assessed by a nurse and a senior paediatrician. Nurse ETAT assessment was compared to standard emergency advanced paediatric life support (APLS) assessment by the paediatrician. Sensitivity, specificity, and predictive values were calculated and appropriateness of nurse treatments was evaluated. RESULTS: The ETAT algorithm as used by nurses identified 731/3837 patients (19.05%); 98 patients (2.6%) were classified as needing emergency treatment and 633 (16.5%) as needing priority assessment. Sensitivity was 96.7% with respect to APLS assessment, 91.7% with respect to all patients given priority by the paediatrician, and 85.7% with respect to patients ultimately admitted. Specificity was 90.6%, 91.0%, and 85.2%, respectively. Nurse administered treatment was appropriate in 94/102 (92.2%) emergency conditions. CONCLUSIONS: The ETAT algorithm and treatment instructions, when carried out by nurses after a short specific training period, performed well as a screening tool to identify priority cases and as a treatment guide for emergency conditions.
