Computerized Physician Order Entry: Reluctance of Physician Adoption of Technology Linked to Improving Health Care

ProQuest LLC, D.I.T. Dissertation, Walden University
Physicians are the influential force in the complex field of patient care delivery. Physicians determine when and where patient healthcare is delivered and affect 80% of the money spent on it. Computerized systems used in the delivery of healthcare information have become an integral part that physicians use to provide patient care. This study concentrated on one such system used by physicians: Computerized Physician Order Entry (CPOE). Study results have shown that physician use of CPOE systems has significantly reduced healthcare costs and improved patient care and safety. The purpose of this study addressed computer usage behavior among physicians in a multi institutional and multi vendor setting. The theoretical foundation for the study was provided by a combination of theory of planned behavior and the theory of reasoned action by applying Davis's Technology Acceptance Model (TAM), which is used to define Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) among users of this technology. Data for this quantitative study were collected with a web-based survey instrument, distributed via e-mail to 422 respondents, and analyzed using multiple linear regression. A best-subsets modeling selection was used that compared all possible models and displayed the best fitting independent predictor variables to determine the influence exerted on the dependent variable of physician computer usage. These findings can be used by institutional administrators, physicians, and CPOE vendors in understanding factors that contribute to non-use (rejection) and use (acceptance) of CPOE systems by physicians. Social change implications of this study provide foundations for improving patient care outcomes while reducing medical costs and errors. Positive social benefits will be accrued to those organizations that are in the process of transitioning to an enterprise wide CPOE system.
