Which physicians have access to electronic prescribing and which ones end up using it?

Area of Science:

• Health Informatics
• Medical Practice Management
• Health Services Research

Background:

• Electronic prescribing (e-prescribing) offers potential benefits for patient safety and healthcare efficiency.
• Understanding physician adoption and utilization patterns is crucial for successful implementation.

Purpose of the Study:

• To examine the availability and utilization of e-prescribing among physicians in the United States.
• To identify physician subgroups with varying levels of e-prescribing access and use intensity.

Main Methods:

• Utilized nationally representative data from the 2004-2005 Community Tracking Study Physician Survey.
• Employed Exhaustive Chi-squared Automatic Interaction Detection (CHAID) for detailed statistical segmentation of physician subgroups.

Main Results:

• E-prescription adoption is increasing, but physician utilization rates are relatively low.
• Utilization varied significantly by practice size, type, physician age, gender, and ethnicity.
• Specific subgroups, including female physicians in surgical specialties and Hispanic physicians in primary care, showed particularly low e-prescription use.

Conclusions:

• Segmentation analysis reveals key barriers to e-prescription adoption and utilization.
• Findings can inform the development of targeted interventions to accelerate e-prescribing system implementation in physician practices.
