Accuracy of serology for the diagnosis of Helicobacter pylori infection--a comparison of eight kits.

AIMS: To determine the accuracy of eight commercially available kits for the serological diagnosis of Helicobacter pylori infection, and hence whether a serology service could be introduced to reduce endoscopy workload. METHODS: Eighty four patients newly presenting to their general practitioners with dyspepsia were recruited. Gold standard diagnosis of H pylori infection was obtained both by a histological examination of gastroduodenal biopsy specimens and by the 14C-urea breath test (UBT). The performance of six quantitative and two qualitative enzyme linked immunosorbent assays for H pylori IgG, used according to the manufacturers' instructions, with serum samples obtained during the endoscopy visit, were compared. RESULTS: The study population had a median age of 45 years, and the prevalence of H pylori infection was 35%. With one exception, where the patient had received a course of anti-H pylori treatment between endoscopy and UBT, there was 100% concordance in the results of the two gold standard techniques. Discordant serology results were more common in patients aged > 50 years (42% of the total) than in younger patients (21%), and this was most noticeable in uninfected patients. The sensitivity of the kits was good (90-100%), but specificity was more variable (76-96%), and the rate of equivocal results was unacceptably high in some cases (0-12%). The overall accuracy of the kits ranged from 83 to 98%. Two kits in particular performed well (Pylori-Elisa II, Bio-Whitaker and Premier, Launch; qualitative) with 98% and 100% accuracy, respectively. CONCLUSIONS: In a symptomatic population with a prevalence of H pylori infection of 35%, particularly in patients aged < 50 years, some but not all serology kits may be used as a highly accurate and inexpensive alternative to the gold standard techniques.

Do cage scores predict readiness to reduce alcohol consumption in medical in-patients?

Four-hundred-and-twenty-three medical in-patients received the CAGE, brief Michigan Alcohol Screening Test (MAST) and Readiness to Change (RCQ) questionnaires. Those positive on the CAGE and MAST were more likely to be in contemplation and action phases of the RCQ, suggesting that simple questionnaires identify patients who not only have drinking problems but are ready to make changes to combat them.

Training for medical teachers: a UK survey, 1993.

Opportunities and resources for training of medical teachers have been criticized in recent UK reports. A survey of undergraduate and postgraduate medical deans showed that training courses were available at most institutions, though only a few were specifically designed for medical teachers. Many new and specific courses are being planned and many new appointments are being made in medical education at both medical school and postgraduate levels. While the outcome of greater resources for training of medical education cannot yet be determined, we conclude that criticisms are being speedily addressed.

Preregistration house officers in the Thames regions: changes in quality of training after four years.

OBJECTIVE: To measure changes in the training and workload of preregistration house officers over four years. DESIGN: Postal questionnaire. SETTING: The Thames health regions. PARTICIPANTS: 1049 preregistration house officers. RESULTS: Response rate was 69% (725 replies). The proportion of house officers officially on duty > 83 hours a week fell from at least 42% to 21%, and the proportion officially on duty < or = 72 hours rose from no more than 9% to 40%. Adequate guidance in breaking bad news increased from 25% to 46% (p < 0.0001; 95% confidence interval for difference, 16.2% to 25.8%) and guidance in pain control increased from 36% to 46% (p < 0.01; 5.0% to 15.0%). The number of house officers attending an induction course increased from 61% to 94% (p < 0.001; 28.9% to 37.1%). There was no change in the proportion unable to attend formal educational sessions because of clinical commitments or in levels of satisfaction with consultants' educational supervision. The median number of inpatients under house officers' care fell from 20 to 17, but the numbers of patients clerked in an average week showed little change. House officers were less satisfied with the clinical experience their post provided (proportion dissatisfied rose from 30% to 39%; p < 0.01; 4.2% to 13.8%) and less enthusiastic about recommending their post to a friend (proportion neutral or not recommending rose from 30% to 42%, p < 0.0001; 7.9% to 16.9%). CONCLUSION: Despite progress in reducing hours of duty and providing induction courses, the training that hospitals and consultants provide for house officers is still unsatisfactory and inconsistent with the General Medical Council's recommendations.

Preregistration house officers in eight English regions: survey of quality of training.

OBJECTIVE: To assess the quality of preregistration house officer training in eight English regions. DESIGN: Postal questionnaire. SETTING: Thames, East Anglian, Mersey, Northern, and Wessex regions. PARTICIPANTS: 1670 preregistration house officers. MAIN OUTCOME MEASURES: Education, hours of work, workload, conditions of work, and attitudes to job and medicine as a career. RESULTS: Response rate was 69% (1146 replies). Most house officers had attended induction courses (1036/1129 (92%)); 74% (757/1024) found them satisfactory. The proportions who had never received adequate guidance on how to break bad news and how to control pain were 59% (670/1135) and 56% (634/1136) respectively. There was much variation between regions. Overall, 65% (736/1138) reported confidence in performing cardiopulmonary resuscitation. Most respondents (95% (1089/1142)) worked an on call rota, 3% (36) a partial shift, and 0.6% (seven) a full shift; 19% (202) were on duty for average weekly hours that exceeded the targets for 1 April 1993. House officers had a median of 20 patients under their care and clerked a median of 10 emergency cases, six routine cases, and two day cases a week. Over half (690/1128 (61%)) could not obtain hot food after 8 pm, 20% (223/1095) did not always have clean sheets available in their on call room, and 45% (462/1036) did not consider the protection of staff against violence to be adequate at their hospital. The most important problems with the preregistration year were inappropriate or non-medical tasks (ranked first by 360 respondents), hours of work (359), and pay for out of hours work (167). Overall 57% (646/1125) would encourage a friend to apply for their post, but only 24% (266/1112) would encourage a friend to take up medicine and 44% (494/1112) would discourage the idea. CONCLUSIONS: House officers' training is deficient in important respects, with inappropriate tasks and heavy clinical workloads impeding the provision of proper education.

CPR and the RCP (2). Training of students and doctors in UK medical schools.

We asked British medical schools and teaching hospitals about the training they offer to medical students and hospital doctors in cardiopulmonary resuscitation. The response rate was 96%. Training that is practical and consistent with guidelines is offered to nearly all students and house officers, often by consultants. Training for other junior doctors and consultants is much less common. The organisation of training is haphazard, and many hospitals have no resuscitation training officers. As a result, few doctors receive the frequent retraining needed to maintain competence in managing cardiopulmonary arrest.

Allocation of junior hospital doctors to pre-registration posts: does Britain need a national matching scheme?

The attitudes of British postgraduate deans and senior medical students to the introduction of a national pre-registration house officer allocation scheme were investigated by postal questionnaire. Several postgraduate deans expressed interest, but most were not in favour of the proposal. Students held similar views. The advantages and disadvantages of a national scheme are discussed.

Preregistration house officers in the four Thames regions: I. Survey of education and workload.

OBJECTIVE: To assess the education and workload of preregistration house officers in the four Thames regions. DESIGN: Postal questionnaire. SETTING: Teaching and non-teaching hospitals in the four Thames regions. PARTICIPANTS: 1064 Preregistration house officers. RESULTS: Response rate was 70% (740 replies). Nine per cent of house officers (66/729) worked a rota of one in two. The average house officer had 20.4 inpatients under his or her care and admitted 23.2 patients per week. Sixty two per cent of house officers (459/740) felt that they spent an excessive amount of time on non-medical tasks of no educational merit; 75% (546/725) had never received adequate guidance on breaking bad news and 64% (467/729) had never received adequate guidance on pain control; 34% (249/731) did not feel confident that they could perform cardiopulmonary resuscitation unsupervised. House officers would tend to recommend their post to a friend. CONCLUSIONS: There are deficiencies in preregistration training in the four Thames regions. The General Medical Council's requirements are not being heeded.

Preregistration house officers in the four Thames regions: II. Comparison of education and workload in teaching and non-teaching hospitals.

OBJECTIVE: To detect differences in the education and workload of preregistration house officers working in teaching and non-teaching hospitals. DESIGN: A postal questionnaire. SETTING: Teaching and non-teaching hospitals in the four Thames regions. PARTICIPANTS: 1064 Preregistration house officers. RESULTS: Response rate was 61% for teaching hospitals and 73% for non-teaching hospitals. House officers in teaching hospitals had significantly fewer inpatients under their care (house physicians 16.9 v 22.9, house surgeons 17.9 v 20.3) and admitted fewer emergency patients per week (house physicians 7.7 v 12.7, house surgeons 6.5 v 9.8). More house officers in teaching hospitals reported that they had too few patients to provide adequate clinical experience. More of their time was consumed by administrative activities devoid of educational value. CONCLUSION: Preregistration house officer posts at teaching hospitals provide less clinical activity and are perceived as less educationally satisfactory by their holders than those elsewhere.

The allocation of pre-registration house officer posts in the four Thames regions: a survey of house officer opinion.

The satisfaction of pre-registration house officers with the operation of, and outcome of participation in, their medical school's allocation scheme for house officer posts was investigated by postal questionnaire. Satisfaction with outcome was generally high. Significant differences are reported between medical schools in participation rates in allocation schemes and in satisfaction with the operation of the schemes. The operation of the ranking schemes used at Guy's and St Bartholomew's Hospitals is shown to be significantly less satisfactory. Reasons for these findings are examined.

The allocation of house officer posts: a UK survey.

The methods of allocation of house officer posts at British medical schools were investigated by postal questionnaire. Three categories were found: a free market, a matching process between student and consultant preferences, and the use of in-course assessments, the matching process being the most popular. Many medical schools had changed their method of house officer allocation since 1969, but often with unsatisfactory results.
