Relationships between preventive activities, psychosocial factors and recurrence of venous leg ulcers: a prospective study.

AIM: The aim of this study was to identify relationships between preventive activities, psychosocial factors and leg ulcer recurrence in patients with chronic venous leg ulcers.
BACKGROUND: Chronic venous leg ulcers are slow to heal and frequently recur, resulting in years of suffering and intensive use of healthcare resources.
METHODS: A prospective longitudinal study was undertaken with a sample of 80 patients with a venous leg ulcer recruited when their ulcer healed. Data were collected from 2006 to 2009 from medical records on demographics, medical history and ulcer history; and from self-report questionnaires on physical activity, nutrition, preventive activities and psychosocial measures. Follow-up data were collected via questionnaires every 3 months for 12 months after healing. Median time to recurrence was calculated using the Kaplan-Meier method. A Cox proportional-hazards regression model was used to adjust for potential confounders and determine effects of preventive strategies and psychosocial factors on recurrence.
RESULTS: There were 35 recurrences in a sample of 80 participants. Median time to recurrence was 27 weeks. After adjustment for potential confounders, a Cox proportional hazards regression model found that at least an hour/day of leg elevation, 6 or more days/week in Class 2 (20-25 mmHg) or 3 (30-40 mmHg) compression hosiery, higher social support scale scores and higher General Self-Efficacy scores remained significantly associated (P < 0·05) with a lower risk of recurrence, while male gender and a history of deep vein thrombosis remained statistically significant risk factors for recurrence.
CONCLUSION: Results indicate that leg elevation, compression hosiery, high levels of self-efficacy and strong social support will help prevent recurrence.
