Accordingly, computerized physician order entry (CPOE) warrants detailed evaluation. Mixed results have been reported about benefit this system. No review its application surgical patients to date. We present implementation CPOE management within an academic multispecialty practice.

Other metrics evaluated included medication errors, order-implementation times, efficiencies, personnel requirements, time. Sampling time span for placement process was assessed with direct hidden observation provider. Results A total 15 (0.22%) errors discovered 6,815 procedures performed during 6 months before use. After implementation, 10 found (5,963 [0.16%]) initial 13 (0.21%) second (6,106 procedures) (p = NS). Mean from nurse receipt 41.2 minutes per (2.05 finding chart, 0.72 writing order, 38.4 unit secretary transcription) compared 27 seconds using Conclusions Present technology can allow major efficiency gains, but refinements will be required improvements patient safety.
