General practitioners' subjective experience of surgery workload.
General practitioners (GPs) in the U.K. frequently cite heavy workload as a major source of work-related stress. However, there is little direct evidence either to support this claim or to suggest whether the source of this stress lies in the amount, or rather the type, of work undertaken. The present paper uses a within-subjects design to address these issues in the surgery context. Over a two-week period three GPs gave ratings of subjective workload following each of their surgeries (N = 20-23). Correlational analysis showed a wide range of surgery characteristics to predict the GPs' reactions, including the length of surgeries, the number of consultations, the number of re-presentations, and the number of follow-ups and investigations requested. The GPs' perceptions of their patients (e.g. in terms of their health status and the appropriateness of the consultation), in contrast, did not emerge as significant predictors. The results of multiple regression analyses, however, revealed that most of the first-order effects could be accounted for by surgery length. Thus while the study supported the hypothesised link between the overall level of surgery work demands and the subjective experience of workload, it failed to confirm any consistent additional effects of the type of work involved. It was also found that as the length of surgeries increased, the GPs were more likely to arrange follow-up appointments. The implications of the present findings are therefore two-fold.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients' views on health screening in general practice.
This paper describes the reactions of 159 patients to the way in which they were invited to participate in a health screening programme and their views on the screening appointment itself. It was found that those invited by letter, rather than opportunistically during a routine consultation, thought their appointment time harder to keep. A group of patients identified as relatively infrequent consulters were less likely to believe that the invite showed the practice to be interested in their health. However, overall the patients' perceptions of both the way in which they were invited and the screening appointment itself were found to be very positive and their satisfaction ratings high.

The potential and limitations of opportunistic screening: data from a computer simulation of a general practice screening programme.
Given the continuing emphasis on preventive medicine in general practice, there is considerable interest in the relative effectiveness of different ways of inviting patients to attend for screening. Recently, opportunistic methods have been advocated as being particularly useful but these methods often fail to reach a high proportion of the target population. Many patients do not consult and when they do they are not always invited to attend for screening. In this study a computer simulation model has been used to examine the effects of these variables in more detail. The notes of a random sample of 190 patients (97 women, 93 men) aged 30-50 years, registered with one general practitioner, were used to provide data for the model. The simulation model showed that increasing the number of screening appointments available each week has only a small effect on screening rates and that a ceiling is reached when 25 appointments per 1000 patients are available. In contrast, increasing the proportion of eligible consulting patients who are invited has a substantial effect such that it could take nearly 12 years to screen 90% of a target population if only one out of every four patients were invited compared with under four years if three out of every four patients were invited. The results suggest therefore that opportunistic screening methods are unlikely to achieve desired screening rates within acceptable time limits. It is argued that to achieve target levels of screening, practices will need to combine opportunistic methods with more formal methods of invitation.

An interactive computerized protocol for the management of hypertension: effects on the general practitioner's clinical behaviour.
This paper reports an experimental study of general practitioners' use of an interactive computerized protocol for the management of hypertension, focussing particularly on the protocol's effects on doctors' clinical behaviour. Prior to its computerization a paper-based version of the protocol was used enabling a comparison of the alternative forms. Doctors' delivery of care was assessed from video recordings of 89 consultations and from the records made during these consultations. Comparisons were made of consultations conducted under control and experimental conditions. Use of paper and computer protocols resulted in significant improvements in the doctors' delivery of care, in terms of the range of verbal and physical examinations conducted and recorded. The protocol's effects were most marked when the computerized version was used. However, use of the computer protocol resulted in the recording of information on the non-occurrence of certain events which had not been explicitly elicited during the verbal examination; features of the design which were intended to encourage adherence to the protocol may have been inappropriate to the realities of a general practice consultation. The findings provide some useful insights for the design of future computerized protocols for the management of chronic conditions.
