Day case surgery trends in England: the influences of target setting and of general practitioner fundholding

Randomized comparison of two anti-emetic strategies in high-risk patients undergoing day-case gynaecological surgery

BACKGROUND

Postoperative nausea and vomiting (PONV) is a significant cause of morbidity among patients undergoing general anaesthesia. The optimal strategy for prevention of PONV, however, remains unclear. This study compared two commonly used prophylactic strategies in high-risk, day-case, gynaecological surgery patients.

METHODS

We conducted a randomized trial comparing sevoflurane combined with dolasetron (SD), with propofol-based total intravenous anaesthesia (TIVA) in 126 high-risk patients undergoing day-case gynaecological surgery. The primary endpoints included the incidence and severity of nausea or vomiting before discharge and the incidence of nausea or vomiting between discharge and 24 h. To identify the factors most predictive of a complete response (no PONV at any time within the 24 h period), multiple logistic regression models were fitted.

RESULTS

Before discharge, there was no significant difference between the two treatment groups with respect to nausea and vomiting outcomes (P = 0.3). Post-discharge nausea and vomiting (PDNV), however, were significantly more common for patients in the TIVA group (nausea, P = 0.004 and vomiting, P = 0.03). Type of anaesthetic, adjusted for weight and anaesthesia duration was significantly associated with complete response (odds ratio = 2.7, 95% confidence interval = 1.15 to 6.4).

CONCLUSIONS

Although both TIVA and dolasetron prophylaxis reduce the predicted rate of PONV in the early postoperative period, the anti-emetic effects of propofol are short-lived. A longer-acting drug such as dolasetron may therefore be necessary to prevent PDNV.

Reduction in the use of surgery for glue ear: did national guidelines have an impact?

BACKGROUND

It is widely accepted that the passive dissemination of national clinical guidance has little or no impact on practice.

OBJECTIVE

To assess the impact in England of an Effective Health Care bulletin on childhood surgery for glue ear issued in 1992 and to understand the reasons for any change (or lack of change) in practice that ensued.

METHOD

Time series analysis of the rate of use of surgery by children under 10 years of age from 1975 to 1997/8 in 13 English health districts.

RESULTS

Following a rise in the rate of surgery in public (National Health Service) hospitals from 1975 to 1985, the rate declined by 1.6% a year from 1986 to 1992/3. Following publication of the guidelines in November 1992, the rate of decline increased to 10.1% a year. Even after allowing for a slight increase in the use of independent (private) hospitals between 1992/3 and 1997/8, the overall rate of decline was at least 7.9%. It appears that the rate of referral of cases by primary care physicians (general practitioners) halved during this period. Several contextual factors are thought to have contributed to the effect of the guidelines, including pre-existing professional concern about the value of surgery, the introduction of an internal market into the NHS, and growing apprehension among parents fuelled by scepticism in the mass media. During this unprecedented period of rapid change in usage, staff delivering the service remained unaware of the alterations in their own practice.

CONCLUSIONS

Passive dissemination of national guidelines can accelerate an existing trend in clinical practice if the context is hospitable. Policy makers should identify and target such situations.

Efficiency of care at the primary-secondary interface: variations with GP fundholding

The aim of the study was to investigate the processes of referral for out-patients care and the interface with general practice, from the perspective of the patient, the patient's general practitioner and hospital specialist. The analyses reported here present variations with fundholding and non-fundholding general practice. The design was a questionnaire survey of out-patients, their hospital specialists and general practitioners, in six, randomly sampled district health authorities in the North Thames Region, with stratification by area. The measures included validated items and scales on process, quality and patient satisfaction with services. Fundholders were more likely to have technical equipment and services available within the practice. There were no differences between fundholders and non-fundholders and the number of out-patient attendances made by their patients, hospital out-patient waiting list times, patients' waiting times in hospital clinics, nor in patients' satisfaction with out-patients and other process indicators. Fundholding is currently being replaced with the proposed wider locality commissioning schemes, with GPs, health authorities and other purchasing bodies acting in partnership. Health authority commissioning will be required to reflect the preferences of GPs. Participants in these schemes will need to pay particular attention to the areas where research indicates that fundholding GPs made little difference to increasing the efficiency and effectiveness of health care both in their own practices and at the primary-secondary care interface.
