Efficiency Gains with Computerized Provider Order Entry

Excerpt

Objective: The objective of this project was to measure efficiency gains in turnaround times with the implementation of a computerized provider order entry (CPOE) system. Methods: Pre- and post-CPOE turnaround times (TATs) were measured for orders placed for laboratory, radiology, and pharmacy. The pre-CPOE group was nonrandomized and included a convenience sample of 240 patients with a sample of 1,420 total orders (laboratory N = 340; radiology N = 490; and pharmacy N = 590). The post-CPOE group was randomized and included 241 patients with a sample of 2,390 total orders (laboratory N = 750; radiology N = 680; and pharmacy N = 960). Results: TATs were statistically significantly lower (P < 0.0001) in all three departments: laboratory TATs decreased 54.5 percent, from 142 to 65 minutes; radiology TATs decreased 61.5 percent, from 31.0 to 11.9 hours; pharmacy TATs decreased 83.4 percent, from 44.0 to 7.3 minutes. Conclusion: Implementation of CPOE resulted in dramatic improvements in TATs, which, in turn, can lead to more timely treatment of patients and enhanced communication of results to providers. It also supports the effort to improve quality of patient care and patient safety.
