A review of the factors influencing nonrecurrence of venous leg ulcers.

The literature on external prevention strategies for recurrence of venous leg ulcers is reviewed to assess the extent of existing knowledge and the effectiveness of preventive practices currently employed. Although there is some evidence that the use of compression hosiery is effective in reducing the incidence of recurrence, other strategies cited for ulcer prevention are not supported by documented research. It is also evident that patient compliance with wearing compression hosiery could be improved and that an evaluation of the effectiveness of hosiery currently available is overdue. With district nurses spending up to 50% of their time treating venous leg ulcers, not only are they in a key position to disseminate information on effective prevention to patients, but in so doing they should contribute to a reduction in their leg ulcer treatment caseload. To do this, nurses need to be more informed on aspects of venous leg ulceration and prevention strategies.
