Few studies examine technical barriers, such as usability, to successful Computerized Provider Order Entry (CPOE) system implementation. This thesis explores this literature gap through the evaluation of the Sunnybrook CPOE order set system with a heuristic evaluation of the Sunnybrook CPOE system, the development of a more user friendly CPOE order set interface (Test Design), and a usability study comparing three order set formats (Sunnybrook CPOE, Test Design, and paper order sets). A randomized trial was conducted with 27 Sunnybrook physicians at the hospital. Results showed that the Sunnybrook CPOE order set system was less efficient (task times were on average 364 seconds longer than Test Design and 344 seconds longer than paper), less user-friendly (users were less confident, less satisfied, and more frustrated with Sunnybrook CPOE tasks), and less safe than paper order sets (more harmful errors). Test Design was as efficient and safe as paper order sets.
