Reports on a study which aimed to initiate a quality assurance process among health care personnel in Sweden. An epidemiological survey concerning treatment of leg ulcers in a defined region in Sweden was conducted and the costs of treating leg ulcers at different levels of care were analysed. The epidemiological survey provided the data necessary to calculate the socio-economic costs for the treatment of leg ulcers. The weekly cost was found to be about 24 times higher for hospital inpatients than it was for patients treated at home. The quality assurance process has continued through an interdisciplinary regional consensus conference and the establishment of a consensus programme in the region, with targets and general suggestions for the care and treatment of leg ulcers. To maintain high quality in leg ulcer treatment in the region, an interdisciplinary reference group has been established with members from different clinics at the hospital and members from the primary health care.
