[Management of venous leg ulcer by French physicians, diversity and related costs: a prospective medicoeconomic observational study].

OBJECTIVES

The purpose of this study was to better ascertain how French physicians manage venous ulcers of the lower limbs. We explored the various therapeutic approaches used and their respective costs. Particular attention was focused on dressing prescriptions.

MATERIAL AND METHODS

A prospective medicoeconomic study was conducted. Eight hundred general practitioners and specialists throughout France were included and followed two patients each, one with a "new ulcer" (less than two weeks) and another with a "longstanding ulcer" (more than six weeks). Patients were followed to healing or for up to six months. An observation chart was completed at each visit. Data collected were characteristics of the ulcer at inclusion, assessment of the clinical course, and the nature and the volume of medical care prescribed. Corresponding costs (total cost for the society) were calculated on the basis of 1996 public prices for drugs and the French national health insurance quotations for ambulatory care. For hospital care, cost was calculated from the cost of stay for homogeneous patient groups.

RESULTS

Files established for 1,098 patients by 652 physicians could be assessed. Elderly female patients predominated in this population (mean age 72 years, 74% women). The length of the ulcer at inclusion was significantly correlated with its duration: 2.82 cm for new ulcers (52.6% of the cases) versus 5.03 cm for longstanding ulcers (47.3%). The mean number of consultations for all patients was 4.8 over a 29-day period. Mean cost resulting from these consultations was 5,827 FF per patient: 48% for care, 33 for drugs, 16% for hospitalizations, and 3% for work lay-off ). Cure was achieved in 77% of the cases within a mean delay of 3 months. Older ulcer was significantly associated with longer treatment (117 days for longstanding ulcers versus 80 days for new ulcers), lower cure rate (67% versus 86%) and higher cost (7 078 FF versus 4 669 FF). Dividing care methods between those using cleaning with compression or not showed that compression was prescribed in 76% of the cases at the inclusion consultation. This predominance of compression therapy did not preclude use of a variety of other therapeutic methods depending on the clinical and demographic situation of the patient. Cost varied accordingly with a mean ranging from 3 160 FF to 6 697 FF depending on the therapeutic attitude. The study also focused on the type and amount of dressings used. Dressings were prescribed for 56 patients in this series. It can be hypothesized that these patients already had dressings. Different indicators show that the absence of prescriptions for dressings concerned less severe and less costly ulcers (4 130 FF versus 5 918 FF for those with dressing prescriptions). Among the 1 042 patients for whom dressings were prescribed, 35% were for occlusive dressings, 29% for ointment dressings and also 24% for both occlusive and ointment dressings. The type was not specified in 55% of the cases. Mean cost for these different categories ranged from 4 921 to 7 019 FF.
