Communicating Hospital Infection Data to the Public: A Study of Consumer Responses and Preferences

Abstract

There is growing interest in public reporting of health care performance data relating to healthcare-associated infections (HAIs). This study evaluated different approaches for reporting hospital-level comparative data on HAIs and the extent to which such data might influence hospital choice. Eight versions of a report were developed, varying whether data were consistent across indicators, whether data were presented in text or graphs, and whether confidence intervals were included. A report and a questionnaire were mailed to a randomly selected sample of local residents. Findings provide no evidence that consistency of indicators, data presentation, report format, or inclusion of confidence intervals significantly impacted consumers' understanding. More educated consumers reported greater understanding of the reports. Responses suggested that public reporting of comparative data on HAIs could influence hospital choice, but other factors including prior experience, reputation, physicians' recommendations, and insurance coverage are also influential. Most consumers understand information on HAIs when it is presented in a short, simple report, and most correctly select the best or worst hospital. Consumers may be influenced by such data, but other factors are likely to be as or more important. (Am J Med Qual 2009;24:108-115)
