Bonis PA, Pickens GT, Rind DM, Foster DA. Association of a clinical knowledge support system with improved patient safety, reduced complications and shorter length of stay among Medicare beneficiaries in acute care hospitals in the United States. Int J Med Inform. 2008 Nov;77(11):745-53.

The authors examined the impact of evidence-based knowledge (provided mainly from UpToDate) on attending physicians' treatment decisions about hospitalized patients.Before being provided information, most attending physicians believed that they had made an evidence-based choice. After reading the information:

  • Demonstrated strong association between hospital quality and efficiency and use of UpToDate.
  • Hospitals with access to UpToDate performed significantly better on risk-adjusted measures of patient safety and complications and had significantly shorter length of stay (by an average 0.167 days per discharge) compared with hospitals without access. These benefits correlated with how frequently UpToDate was used.
