Assessing the Safety of Electronic Health Records: A National Longitudinal Study of Medication-related Decision Support

摘要: Background Electronic health records (EHR) can improve safety via computerised physician order entry with clinical decision support, designed in part to alert providers and prevent potential adverse drug events at before they reach the patient. However, early evidence suggested performance preventing was mixed. Methods We used data from a national, longitudinal sample of 1527 hospitals USA 2009 2016 who took assessment test using simulated medication orders how well their EHR prevented errors for patient harm. calculated descriptive statistics on over time, by years hospital experience across characteristics. Finally, we ordinary least squares regression identify characteristics associated higher performance. Results The average system correctly only 54.0% tested 44-order 2009; this rose 61.6% 2016. Hospitals that multiple times performed better subsequent than those taking first 55.2% year 70.3% eighth, suggesting efforts participate voluntary self-assessment improvement may be helpful improving Conclusion Hospital has improved time but is far perfect. specifics implementation play key role realising benefits computerising prescribing, as organisations have substantial latitude terms what implement. Intentional quality appear critical high indicate importance culture safety.
