Self-efficacy expectation, behavior performance, and mood status in early recovery from percutaneous transluminal coronary angioplasty.

OBJECTIVE: To describe levels of self-efficacy expectation and performance of selected cardiac recovery behaviors and mood state in patients recovering from percutaneous transluminal coronary angioplasty (PTCA) and to describe the nature of the relationships among these variables. DESIGN: Descriptive, correlational. SETTING: Hospital (postprocedure, predischarge) and home (2 weeks postdischarge). MEASURES: Jenkins Self-Efficacy Expectation Scales and Activity Checklists for Walking Various Distances, Following a Dietary Restriction, Maintaining Health, Resuming Roles and Working; and the Profile of Mood States (POMS) Inventory (McNair, Lorr, and Doppleman). PATIENTS: Adult patients (N = 90; 79% men; mean age = 61 years; 50% working preprocedure) who had undergone a PTCA (first procedure 71.1% and elective procedure 77.8%). Mean hospital stay was 3.9 days. RESULTS: Mean self-efficacy expectation scores were moderately high postprocedure for all behaviors and all, except scores for role resumption, increased significantly (p < 0.01) by 2 weeks postdischarge. Self-efficacy expectation scores were significantly and positively related to behavior performance for all study behaviors except work at 2 weeks, with r values ranging from 0.26 to 0.85. Mean total mood state (POMS) scores improved significantly (p < 0.01) over the 2-week period. Those with higher efficacy expectation scores tended to have higher behavior performance scores and lower levels of mood disturbance. It was noted that the level of mood disturbance was low at both data collection points. CONCLUSIONS: These findings demonstrate the predictive ability of self-efficacy expectation related to behavior performance and describe the relationships of these variables with total mood state as measured by the POMS. Clinical implications drawn from these findings support the individualization of patient teaching needed for this population and point to the need for further research, including development of more clinically useful instruments for assessing these variables.

Controlled trial of direct physician order entry: effects on physicians' time utilization in ambulatory primary care internal medicine practices.

OBJECTIVE: Direct physician order entry (POE) offers many potential benefits, but evidence suggests that POE requires substantially more time than traditional paper-based ordering methods. The Medical Gopher is a well-accepted system for direct POE that has been in use for more than 15 years. The authors hypothesized that physicians using the Gopher would not spend any more time writing orders than physicians using paper-based methods. DESIGN: A randomized controlled trial of POE using the Medical Gopher system in 11 primary care internal medicine practices. MEASUREMENTS: The authors collected detailed time use data using time motion studies of the physicians and surveyed their opinions about the POE system. RESULTS: The authors found that physicians using the Gopher spent 2.2 min more per patient overall, but when duplicative and administrative tasks were taken into account, physicians were found to have spent only 0.43 min more per patient. With experience, the order entry time fell by 3.73 min per patient. The survey revealed that the physicians believed that the system improved their patient care and wanted the Gopher to continue to be available in their practices. CONCLUSIONS: Little extra time, if any, was required for physicians to use the POE system. With experience in its use, physicians may even save time while enjoying the many benefits of POE.
