Overview

Randomized trial shows increased colorectal cancer screening rates in primary care through training and feedback, indicating a potential improvement strategy.

Key Points

  • This study aims to enhance colorectal cancer screening rates among primary care physicians (PCPs) using quality circles (QCs).
  • Pragmatic randomized controlled trial conducted in Switzerland from 2018 to 2021 with PCPs in QCs.
  • Intervention included three training sessions, shared decision-making tools, and performance feedback based on 40 patients per PCP.
  • Data collected from 63 PCPs across 120 invited QCs, monitored over 12 months.
  • In the intervention group, colorectal cancer screening rates were 58% compared to 42% in the control group (OR 1.98; 95% CI: 1.14-3.42).
  • Screening rates in the intervention group increased from 55% to 57.9%, representing a 2.9% absolute increase (OR 1.29; 95% CI: 1.08-1.55, p < 0.01).
