BACKGROUND: Computerized clinical knowledge mana-gement systems hold enormous potential for improving quality and efficiency. However, their impact on clinical practice is not well known. OBJECTIVE: To examine the impact of UpToDate on outcomes of care. DESIGN: Retrospective study. SETTING: National sample of US inpatient hospitals. PATIENTS: Fee-for-service Medicare beneficiaries. INTERVENTION: Adoption of UpToDate in US hospitals. MEASUREMENT: Risk-adjusted lengths of stay, mortality rates, and quality performance. RESULTS: We found that patients admitted to hospitals using UpToDate had shorter lengths of stay than patients admitted to non-UpToDate hospitals overall (5.6 days vs 5.7 days; P < 0.001) and among 6 prespecified conditions (range, -0.1 to -0.3 days; P < 0.001 for each). Further, patients admitted to UpToDate hospitals had lower risk-adjusted mortality rate for 3 of the 6 conditions (range, -0.1% to -0.6% mortality reduction; P < 0.05). Finally, hospitals with UpToDate had better quality performance for every condition on the Hospital Quality Alliance metrics. In subgroup analyses, we found that it was the smaller hospitals and the non-teaching hospitals where the benefits of the UpToDate seemed most pronounced, compared to the larger, teaching institutions where the benefits of UpToDate seemed small or nonexistent. CONCLUSIONS: We found a very small but consistent association between use of UpToDate and reduced length of stay, lower risk-adjusted mortality rates, and better quality performance, at least in the smaller, non-teaching institutions. These findings may suggest that computerized tools such as UpToDate could be helpful in improving care. Journal of Hospital Medicine 2011. © 2011 Society of Hospital Medicine.
