Objective: To determine whether a selected set of indicators can represent a single overall quality construct. Design: Cross sectional study of data abstracted during an evaluation of an initiative to improve quality of care for people with HIV. Setting: 69 sites in 30 states. Data sources: Medical records of 9020 patients. Main outcome measures: Adjusted performance rates at site level for eight measures of quality of care specific to HIV and a site level summary performance score (the number of measures for which the site was in the top quarter of the distribution). Results: Of 28 site level correlations between measures, two were greater than 0.40, two were between 0.30 and 0.39, four were between 0.20 and 0.29, and the 20 remaining were all less than 0.20. One site was in the top quarter for seven measures, but no sites were in the top quarter for six or eight of the measures. Across the eight quality measures, sites were in the top quarter no more often than predicted by a chance (binomial) distribution. Conclusions: The quality suggested by one measured indicator cannot necessarily be generalised to unmeasured indicators, even if this might be expected for clinical or other reasons.
