Computerized prescriber order entry and opiate prescription in ambulatory care visits

To assess the impact of computerized prescriber order entry (CPOE) on opioid-prescribing practices.

This study analyzed 233,390 office-based medical visits in the 2011-2015 National Ambulatory Medical Care Survey. We used survey-adjusted logistic regression analysis comparing prescription of opiate medications by physicians with and without CPOE. Results were adjusted by covariates describing patient demographics, insurance status, and geography; clinical factors including noncancer pain, cancer, and other chronic medical problems; and physician specialty category and solo practitioner status.

Opiates were prescribed in 10.4% of patient visits to physicians with access to CPOE in the sample, compared with 7.5% of visits to physicians without access to CPOE. The adjusted odds of opiate prescription were 1.35 times greater in visits to physicians who had access to CPOE (P = 0.001; 95% CI 1.14-1.58). Among patients visits citing pain (n = 52,978), the adjusted odds of opioid prescription were significantly greater when physicians had access to CPOE (odds ratio 1.28, 95% CI 1.02-1.61; P = 0.035).

These findings support efforts to review and redesign embedded CPOE tools to improve guideline adherence and reduce problematic opiate prescription.
