[Outpatient treatment. What is the evidence?]

In relation to the development of quality standards for the national quality development study, DGMA, a search was made through the literature on outpatient care. The literature was scanty, but some evidence was found on the following: Continuity of care is a patient demand, and several studies show more effective and less expensive treatment when this is ensured. Two studies show impaired quality of treatment, but quality is not defined either precisely or uniformly. Waiting times dissatisfy patients and perhaps diminish the result of treatment and information. Failure to turn up for appointments affects up to 29 per cent of consultations. Non-attendances could be cut down if patient factors and continuity of care are taken into account. Some outpatient consultations could take place in the general practitioner's surgery, if hospital doctors knew more about their capabilities.
