Quality of training in public health in the UK: results of the first national training audit.

OBJECTIVES: Since 1997, UK public health training has undergone major changes, including the creation of specialist registrars (SpRs), introduction of a competency framework, admission of non-medical (specialist) trainees and National Health Service organizational change. It was therefore considered timely to audit the quality of this training. STUDY DESIGN: Cross-sectional survey of all UK public health trainees, conducted in April 2003. METHODS: The survey questions were based on 75 previously identified standards, with three sections: induction (30 standards), health protection (13 standards) and general training (32 standards). Results were calculated for the UK. Deaneries were compared on 10 key standards, as was the training of SpRs and specialist trainees. RESULTS: Two hundred and ninety responses were received (62% response rate). Only 16 (21%) of 75 standards were met by at least 80% of respondents, with problems in induction, health protection, secretarial facilities and examination support. Across 10 key standards (including initial welcome, trainer support, breadth/relevance of work and facilities), 59% indicated that their training had met at least eight standards. Results for individual deaneries were significantly different (P = 0.02), although 13 of 16 had median scores of eight out of 10, or over. Deaneries with specialists scored lower than those without (median scores eight vs nine, P = 0.003). Median specialist and SpR scores on the 10 key standards were seven and eight, respectively (P<0.001). In addition, SpRs were more likely to be 'on-call' [odds ratio (OR) = 66.8, 95% confidence interval (CI) 17.2-259.4, P<0.001] and to feel prepared for this role (OR = 10.7, 95% CI 1.4-79.8) than specialists. CONCLUSION: This was the first UK National Audit of Public Health Training. Few standards were achieved amongst respondents, although the levels set may be considered to be high and the response rate (62%) was less than optimal, potentially biasing results. Despite these caveats, recent organizational change in England appears to have led to significant training disruption among respondents. Nevertheless, repeating such an audit annually within deaneries could help to improve public health training throughout the UK.

Insights into training and examination performance from the first UK National Public Health Training Audit.

OBJECTIVES: To investigate predictors of a supportive training relationship and examination success using data from the first UK Public Health Training Audit. STUDY DESIGN: Secondary analysis of data from a national cross-sectional survey of UK public health trainees, conducted in April 2003. METHODS: All UK public health trainees were sent a questionnaire including questions on training experience and examination performance. Possible predictive factors of a supportive trainer-trainee relationship and success at Part I and Part II of Membership of Faculty of Public Health examinations were first investigated in univariate analyses, and subsequently using logistic regression. RESULTS: Two hundred and ninety responses were received (62% response). Supportive trainers gave feedback [odds ratio (OR) = 11.2, 95% confidence interval (CI) 3.7-34.0, P<0.001], spent at least 1 h/week with their trainee (OR = 5.2, 95% CI 1.7-15.4, P = 0.003), held 3-monthly progress meetings (OR = 2.9, 95% CI 1.4-6.1, P = 0.006), and encouraged wide training experience (OR = 2.5, 95% CI 1.2-5.4, P = 0.016). Predictors of success in the Part I examination by the end of the second year of training were medical background (OR = 4.4, 95% CI 1.6-12.2, P = 0.004) and perceived adequacy of examination support (OR = 4.2, 95% CI 1.7-10.0, P = 0.001). Predictors of success in the Part II examination by the end of the fourth year of training were access to examiners (OR = 4.6, 95% CI 1.3-16.2) and wide experience (OR = 4.1, 95% CI 1.1-14.5). CONCLUSION: Trainees feel supported when provided with adequate trainer contact time, feedback and wide experience. Part I examination success appears to be more likely amongst trainees with a medical background and those given examination support. Part II success is related to the breadth of a trainee's experience and access to examiner support.

Analysing spatially referenced public health data: a comparison of three methodological approaches.

In the analysis of spatially referenced public health data, members of different disciplinary groups (geographers, epidemiologists and statisticians) tend to select different methodological approaches, usually those with which they are already familiar. This paper compares three such approaches in terms of their relative value and results. A single public health dataset, derived from a community survey, is analysed by using 'traditional' epidemiological methods, GIS and point pattern analysis. Since they adopt different 'models' for addressing the same research question, the three approaches produce some variation in the results for specific health-related variables. Taken overall, however, the results complement, rather than contradict or duplicate each other.

'Not too much, not too little, but just enough?': observations on continuing professional development in Public Health in the north of England.

Three inquiries about Public Health continuing professional development were undertaken in the Northern and Yorkshire Region of the National Health Service during 1995-96. Public Health Physicians were asked about their experience of continuing education and for their views on a regional policy for continuing professional development. Health Authority Chief Executives were asked about their reactions to Public Health Physicians continuing educational needs. The overall response rates for the Public Health Physicians were very disappointing. Most of the Chief Executives (a much smaller group) responded to the inquiry. A large minority of Public Health Physicians believed that their continuing education in the preceding two years had been adequate. Most wished their future continuing education activities to be multi-disciplinary. One finding with considerable significance for those managing Public Health education, both specialist and continuing, was that many of those with teaching responsibilities had not been trained to teach. Despite apparent concordance between the views of Chief Executives and those of Public Health Physicians; on some important points there were inconsistencies in the comments of Chief Executives, which suggested lack of understanding of both the roles of their professional colleagues and the need for their continuing education. The inquiries gave rise to a sense of apathy and under-confidence, manifested in some reluctance to accept policing of continuing education. There is a need to experiment with learning and teaching approaches in order to progress from the current traditional educational methods.

Respiratory morbidity 10 years after the Union Carbide gas leak at Bhopal: a cross sectional survey. The International Medical Commission on Bhopal.

OBJECTIVE: To examine the role of exposure to the 1984 Bhopal gas leak in the development of persistent obstructive airways disease. DESIGN: Cross sectional survey. SETTING: Bhopal, India. SUBJECTS: Random sample of 454 adults stratified by distance of residence from the Union Carbide plant. MAIN OUTCOME MEASURES: Self reported respiratory symptoms; indices of lung function measured by simple spirometry and adjusted for age, sex, and height according to Indian derived regression equations. RESULTS: Respiratory symptoms were significantly more common and lung function (percentage predicted forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory flow between 25% and 75% of vital capacity (FEF25-75), and FEV1/FVC ratio) was reduced among those reporting exposure to the gas leak. The frequency of symptoms fell as exposure decreased (as estimated by distance lived from the plant), and lung function measurements displayed similar trends. These findings were not wholly accounted for by confounding by smoking or literacy, a measure of socioeconomic status. Lung function measurements were consistently lower in those reporting symptoms. CONCLUSION: Our results suggest that persistent small airways obstruction among survivors of the 1984 disaster may be attributed to gas exposure.

Long term morbidity in survivors of the 1984 Bhopal gas leak.

BACKGROUND: The extent and nature of long term health sequelae among survivors of the Bhopal gas disaster are not known. In 1994 an International Medical Commission was set up with the aim of assessing respiratory, neurological and other health effects attributable to gas exposure. METHODS: An epidemiological survey of a representative sample of gas-exposed inhabitants of Bhopal was conducted in January 1994; for reference, a group of unexposed persons in the same city were surveyed. Questionnaires regarding health and exposure were administered to 474 persons, and a random sample (n=76) were subjected to respiratory and neurological testing. Responses to the questionnaire and the results of clinical testing were analysed according to a measure of individual gas exposure. RESULTS: A large number of subjects reported general health problems (exposed v. unexposed; 94% v. 52%) and episodes of fever (7.5/year v. 2.5/year); adverse outcome of pregnancy (e.g. still-births, 9% v. 4%) and respiratory symptoms (81% v. 38%), with a strong gradient by exposure category. This was not accounted for by differences in smoking, and was consistent with the results of spirometric testing. Neurological and psychiatric symptoms were reported more frequently by subjects in high exposure categories and the results of neurological examination and testing tended to confirm this finding. Ophthalmic symptoms demonstrated a similar pattern. Although a number of other symptoms were reported (with the possible exception of gastrointestinal disease), there was no clear evidence of other organ system damage attributable to gas exposure. CONCLUSION: The gradient of reported symptoms and clinical test results with estimates of exposure among these survivors of the gas leak suggests that a proportion of their current respiratory and neurological disease was due to gas exposure.

Asthma and factory emissions in northern England: addressing public concern by combining geographical and epidemiological methods.

STUDY OBJECTIVE: The prevalence of asthma was assessed to investigate respiratory health effects of airborne emissions from a factory. A geographical information system allowed flexible definition of study areas in terms of their size, distance, and location in relation to the factory. The value of the approach for this type of investigation is focussed on. SETTING: The factory is located in the south western part of a small market town in County Durham. MEASUREMENTS AND MAIN RESULTS: A total of 1573 asthma cases were identified from general practitioner computerised repeat prescribing systems. Population denominators were defined from family health services authority patient registers. The area within 1 km and immediately to the north east of the factory had an age and sex standardised asthma prevalence 24% (confidence interval 4, 44%) in excess of the expected rate (p = 0.01). The increased prevalence was confined to middle aged and elderly adults living in the area between 0.5 and 1 km to the north east of the factory. CONCLUSIONS: The value of combining the skills of geographers and epidemiologists in addressing public health issues is shown, particularly through the use of geographical information systems which proved powerful and effective.

Establishing baseline data in cancer registration in northern England: implications for Health of the Nation targets.

OBJECTIVE: To assess the completeness and accuracy of cancer surveillance data relevant to Health of the Nation targets. DESIGN: A comparison of locally ascertained data on cancer with recorded cancer registry sources in selected diagnoses. SETTING: The district of South West Durham within the Northern Regional Health Authority. PATIENTS: All patients with lung, skin, and malignant cervical cancer who were resident and diagnosed in the district or identified in the Northern Region Cancer Registry during the calendar period 1989-91. MAIN RESULTS: Of 544 cases of cancer identified from all available sources, 448 (95.8%) were registered, ranging from 93.9% for malignant cervical cancer to 96.7% for skin cancer. In 448 cases which were both identified locally and registered, 53 (11.8%) showed disagreements between local sources and register data, involving classification of site and timing of registration. Twenty three cases were identified locally but were not registered, 22 registered but not identified locally, and 51 registered with the casenotes missing locally. CONCLUSIONS: Any real achievement of Health of the Nation targets may be masked by changes over time in the accuracy and completeness of information systems. In assessing the achievement or otherwise of targets, it is important to be aware of any differences in the completeness and accuracy of the baseline data compared to future measurements.

Public health medicine training and the NHS changes.

The current round of mergers between Health Authorities and Family Health Service Authorities (FHSAs), when set in the competitive context of markets, has profound implications for training in Public Health Medicine. This paper considers the phases in the management of change and the costs, benefits and principles for trainers, trainees and organisations as mergers take place. Particular emphasis is placed on understanding the motives of and learning from the change that is taking place.
