Limited studies have examined electronic prescribing (e-prescribing) adoption in physician office practices. Specifically, none have explored the influence of payer mix on e-prescribing adoption among physicians.
This study examines the impact of practice composition of Medicare, Medicaid, and private insurance on e-prescribing adoption among physicians.
Logistic regression was used to analyze data collected from a large-scale information technology-related survey of Florida physicians.
After controlling for practice and physician characteristics, physicians with the highest (odds ratio = 1.67, 95% confidence interval = 1.01-2.78) and above-average (odds ratio [OR] = 1.83, 95% confidence interval = 1.04-3.22) volume of Medicare patients were significantly more likely to e-prescribe as compared with those in the low-volume category. No differences in adoption were found across all Medicaid and private insurance practice composition categories.
Our findings support the notion that direct incentives, such as those in the Medicare Modernization Act of 2003, may influence physician adoption of e-prescribing.
