Objective: To evaluate the role of compression in non-healing venous leg ulcers (VLUs) of > 3 months' duration.
Method: Patients' records from three independent data sets of non-healing VLUs of > 3 months'duration were re-analysed.Two data sets were separate audits of clinical practice and the third comprised patients' records from a randomised controlled trial. Some patients in each data set were never treated with compression. The effect of compression on healing at 6 months was tested with logistic regression.
Results: In each data set, patients in the compression and no-compression groups were matched according to ulcer size and duration; there were no differences in comorbidities. Comparing the no-compression with the compression groups, the healing rate at 6 months was 68% vs 48% in study 1, 12% vs 6% in study 2, and 26% vs 11% in study 3. Use of compression was found to be an independent predictor of not healing with an odds ratio of 0.422, 0.456 and 0.408 in studies 1, 2 and 3 respectively.
Conclusion: The healing rate of non-healing VLUs of > 3 months' duration in the no-compression groups was double that of VLUs in the compression groups. These findings have the potential for treatment modification if confirmed in a prospective trial.
