Consistency of treatment recommendations in online clinical references
Cross­-sectional analysis

About the Study

Researchers at the Department of Clinical Epidemiology and Biostatistics at McMaster University looked at how likely treatment recommendations in leading clinical information tools are consistent with published evidence. Researchers looked at UpToDate, DynaMed, PIER, and Best Practice. Treatment recommendations were evaluated for 200 clinical topics. The treatment recommendations in the clinical information tools were compared with published evidence. Based on these results, the proportion of topics which required updating was calculated for each online clinical information tool.

Reported Findings

The percent of topics for which published information differed from the online clinical information tools was 23% for DynaMed, 52% for UpToDate, 55% for PIER, and 60% for Best Practice. The average amount of time since the last update for each online clinical information tool was 170 days for DynaMed and 488 days for PIER.
