Outcomes of venous ulcer care: results of a longitudinal study.

A longitudinal study involving 81 patients with venous ulcers was conducted to explore the outcomes and cost of wound care in a home healthcare (HHC) setting and an outpatient care setting. Ulcers were managed with a saline gauze or hydrocolloid dressing and compression hosiery, or covered with an Unna's boot. Outcomes did not vary between physician's office and home care. Patients preferred home care, but costs and charges were much higher for HHC than for patients managed in the physician's office. Recurrence rates and costs varied greatly. Eighty-eight percent of ulcers in the saline dressing group did not heal or recurred compared to 21% of ulcers in the Unna's boot and 13% of ulcers in the hydrocolloid dressing group. The data also suggest hydrocolloid dressings are more cost-effective than Unna's boot or saline-gauze dressings. Controlled clinical studies to ascertain the cost-effectiveness of venous ulcer care in different patient care settings and the use of different treatment modalities, as well as care system oriented toward outcome for the patient rather than service, design, and distribution, are needed.
