Effect of educational interventions on wound healing in patients with venous leg ulceration: A systematic review and meta‐analysis

Educational interventions for patients with venous leg ulceration (VLU) may promote adherence and self‐management, however, their effect on wound healing is unclear. A systematic literature search was performed and randomised controlled trials with a focus on educational interventions were included. Wound healing was analysed by assessing wound healing rate, ulcer size, and the PUSH Score. Additional outcomes comprised pain, quality of life, and functional ability. The study protocol for this work is registered at PROSPERO 2020 (ID: CRD42021286152). Nine studies were included in this meta‐analysis. The odds ratio for wound healing was 1.91 (95% CI, 0.99–3.67, P = .053) in favour of educational interventions compared to usual care. Ulcer size reduction was higher (MD: ‐7.22; 95% CI, −11.91 to −2.53, P = .003) in patients following educational interventions. Included studies also showed significant effects on pain, quality of life, and functional analysis, though no quantitative synthesis was feasible. The overall risk of bias showed some concerns. Educational interventions aim to actively involve patients in their treatment, thereby appearing to be able to have a positive impact on wound healing within 12 weeks. Consequently, integrating educational approaches to routine wound care may be a promising strategy to improve treatment of VLU.
