Write a narrative of 750-1,000 words (not including the title page and references) that presents the research support for the projects problem and proposed solution. Make sure to do the following:

This project identified a problem: medication errors are common in hospitals, which can lead to poor patient outcomes. A computerized physician order entry system (CPOE) with decision support is proposed to decrease medication errors. This solution was supported by several research studies that were found through systematic searches.

You can search using the following method

Searches were made using PubMed, CINAHL and Cochrane Library. The keywords used included decision support and medication error, as well as computerized physician orders entry and decision support. These included studies in peer-reviewed journals that were conducted in a hospital setting and focused on the effectiveness CPOE with decision aid in reducing medication error. Study that was not performed in a hospital or which did not assess the effectiveness of CPOE/decision support were excluded.

Ten research studies were selected for inclusion in the research table. Below is Table 1.

Phansalkar et al. (2010) Observational 8 Hospitals CPOE and clinical decision support Medication errors Alert override rates high Limited generalizability

Summary of Research Studies

Research studies such as the one in this table show consistent evidence of the effectiveness of a CPOE system. There were many designs used in the studies, such as quasi-experimental, randomized controlled trials and observational.
