OBJECTIVE: This study aimed to compare the healing outcomes between three types of compression therapy-two-layer bandage (2LB), four-layer bandage (4LB), and compression stockings, and to identify the predictors of venous leg ulcer (VLU) healing.
METHOD: A retrospective review of the medical records of patients diagnosed with VLU between 2011 and 2016 in Singapore was conducted. Univariate and multivariate analyses were done between healed and unhealed VLU patients at three and six months, based on potential factors, ranging from demographic profile to comorbidities and treatment-related variables.
RESULTS: Data from 377 patients' medical records were analysed. The healing rates with the three types of compression system, 4LB, 2LB and compression stockings, were 22.3%, 34.9% and 8.7% respectively at three months; at six months they were 44.2%, 41.9% and 34.8% respectively. Patients on 2LB reported a significantly higher proportion of healed ulcers at three months (p=0.003) but at six months there was no difference in healing rates between the three types of therapy. At three and six months, the duration of compression therapy was found to be an independent predictor of healing (p<0.001).
CONCLUSION: In this study, the 2LB appeared to show the most favourable healing outcome in the short-term but as VLUs persisted beyond the months, the type of compression system used did not make a difference in the healing outcome. Our findings suggested that, as the duration became more prolonged, VLUs became more resistant to healing despite compression therapy. Therefore, it may be necessary for clinicians to consider adjuvant therapies for hard-to-heal ulcers at an earlier stage.
