Clinical quality indicators of venous leg ulcers: development, feasibility, and reliability.
In the clinical setting, diagnosis and treatment of venous leg ulcers can vary considerably from patient to patient. The first step to reducing this variation is to document venous leg ulcer care through use of quantitative scientific documentation principles. This requires the development of valid and reliable evidence-based quality indicators of venous leg ulcer care. A Scandinavian multidisciplinary, cross-sectional panel of wound healing experts developed clinical quality indicators on the basis of scientific evidence from the literature and subsequent group nominal consensus of the panel; an independent medical doctor tested the feasibility and reliability of these clinical indicators, assessing the quality of medical technical care on 100 consecutive venous leg ulcer patients. Main outcome measures were healing, recurrence, pain, venous disease diagnosis, differential diagnosis and treatment, and inter- and intra-rater reliability. The indicators proved feasible and reliable to measure (inter-rater kappa = 0.79, P < 0.01 and intra-rater kappa = 0.89, P < 0.1). Within 3 months of initial examination, venous etiology was verified by duplex in 61 of the 98 participating patients (62%) and 31 (32%) were assessed for venous surgery. Distal arterial pressure was measured following initial examination in 33 of the patients (34%). All patients (100%) were prescribed compression therapy. Of the 98 patients, 11 (11%) had ulcers recur in 3 months and 72 (73%) healed in 12 months, which is in line with the literature. It is feasible to reliably measure the quality of medical technical venous leg ulcer care in the clinical setting using a few strategic clinically relevant indicators of quality.
