Abstract
The Dundee out-of-hours cooperative (DDOC) was the first of its kind to be developed in a city in Scotland. In its first year of operation, the key features of the cooperative were that (a) two doctors could deal with the large majority of out-of-hours calls for a population of just under 100,000 patients, (b) only one third of calls required a home visit, (c) most calls were handled within a period of time acceptable to patients, (d) seven out of 10 patients rated the service equal to or better than previous services, and (e) there were extended opportunities for general practitioners (GPs) involved in the scheme to meet with other colleagues during out-of-hours work.
