Influences on prescribing in non-fundholding general practices.

BACKGROUND: The experience from general practice fundholding suggests that financial incentives may influence prescribing; guidelines and hospital prescribing are two other suggested influences. AIM: A study was undertaken to establish general practitioners' attitudes to a financial prescribing incentive scheme, the presence and use of guidelines, and the influence of prescribing initiated within secondary care. METHOD: A postal questionnaire survey of non-fundholding general practices in the former Northern Region was conducted. RESULTS: Practices' thinking and subsequent decisions about the incentive prescribing scheme were most often influenced by discussions within the practice (45%). Those practices that achieved their savings under the incentive scheme were less likely than those not achieving savings to feel that the target was not achievable, the time scale was unacceptable, and that the philosophy behind the scheme was unacceptable. Forty-five per cent of practices received advice from neither a medical nor a pharmaceutical adviser; 27% of practices received advice from both, 12% from a medical adviser only and 16% from a pharmaceutical adviser only. Of the practices that tried to make their target savings, 91% intended to increase generic prescribing; fewer than one-third of practices mentioned any other measure. Prescribing guidelines were reported by a minority of practices, although reported rates of use were high when these were present. Clinical guidelines for three conditions, asthma, diabetes and hypertension, were present in more than 50% of practices; 25% of practices had no clinical guidelines. Hospital prescribing was reported as 'always' or 'usually' influencing prescribing for diabetes by 57% of respondents, ischaemic heart disease by 55%, peptic ulceration by 49%, asthma by 42% and hypertension by 39%. CONCLUSIONS: General practitioner prescribing is influenced by a complex web of factors, with no single factor pre-eminent. To understand this area further, there is a need to take each of these areas and ascertain the match between doctors' perceptions and actual practice.
