Summary
Requiring physicians to actively respond to computer reminders improved cancer screening compliance, particularly for older patients. However, complete adherence remains challenging due to data gaps and patient refusals.
Area of Science:
- Primary Care Medicine
- Preventive Health
- Health Informatics
Background:
- Improving adherence to cancer screening protocols like fecal occult blood testing (FOBT), mammography, and Papanicolaou (Pap) testing is crucial for patient outcomes.
- Computer-generated reminders are widely used but their effectiveness can be enhanced.
Purpose of the Study:
- To evaluate the impact of a mandatory physician response system for computer-generated reminders on compliance with cancer screening tests.
- To identify factors influencing compliance rates in a primary care setting.
Main Methods:
- A six-month prospective, randomized controlled trial was conducted in an academic primary care internal medicine practice.
- Physicians (faculty and residents) and 5,407 patients were included.
- Intervention groups required physicians to select a response to reminders (done, not applicable, refused, next visit), while control groups received routine reminders.
Main Results:
- Physicians in the intervention group showed significantly higher compliance rates for combined reminders (46% vs. 38%) and for FOBT (61% vs. 49%) and mammography (54% vs. 47%) compared to the control group.
- Compliance improvements were most pronounced in residents and for patients aged 70 and older.
- Reasons for non-compliance included reminders being not applicable (21%) and patient refusal (10%).
Conclusions:
- Mandatory physician responses to computer-generated reminders can significantly improve adherence to cancer screening protocols.
- The intervention is particularly beneficial for older patient populations where compliance was previously lowest.
- Full compliance is limited by incomplete electronic health record data and patient-related factors such as refusal of screening.
