Satisfaction with a computerized practitioner order-entry system at two military health care facilities

Abstract

User satisfaction with a computerized practitioner order-entry (POE) system at two military health care facilities was studied. A survey was mailed in May 1998 to providers authorized to enter drug orders into the Composite Health Care System (CHCS) (including two clinical pharmacists) and pharmacy Staff members at two department of defense (DOD) medical treatment facilities. Of 189 questionnaires with the potential to be returned completed, 112 were usable, for a net response rate of 59.3%. The internal consistency of the survey items measuring user satisfaction (Cronbach's α) was 0.86. The typical respondent was male, was employed by the DOD, had fair to excellent computer and typing skills, had received eight hours or less of training on the CHCS POE system, had been using the system for two years or less, and had been a health care practitioner for 10 years or less. Overall, users were satisfied with the POE system (mean ± S.D. rating of 3.78 ± 0.87 on a 5point scale where 5 represented the highest satisfaction level). Satisfaction was correlated most strongly with ratings of the POE system's efficiency. Nonphysicians were more satisfied, on average, than physicians. No significant relationship was found between other individual characteristics and satisfaction. Qualitative analysis reinforced the finding that users were interested in efficiency issues. Overall, users at two military health care facilities were satisfied with a computerized POE system. Satisfaction was most strongly correlated with the perceived efficiency of the system.
