This study from the Northern California Kaiser Permanente health care system evaluated the impact of a 30-minute online interactive training program collaboratively developed by endoscopists, endoscopy unit staff, psychologists, and researchers with expertise in behavioral change theory and evidence-based interventions.
In the study conducted in late 2014, 86 endoscopists underwent the new training program. All participating endoscopists completed at least 100 colonoscopies annually for the 3 years before and after the training.
There was an immediate 3.13% increase in the adenoma detection rate (ADR) during the quarter after training. By comparison, ADRs increased by an absolute 0.58% per quarter in the 3 years before training and 0.33% per quarter in the 3 years after. Endoscopists with a pretraining ADR lower than the median ADR of 29% experienced a greater increase in ADR immediately after training, with an absolute mean increase of 4.9%. For each 1% ADR increase, there was a 4% reduction in postcolonoscopy colorectal cancer (PCCRC) risk. Endoscopists with an ADR increase ≥10% produced a 55% lower risk of PCCRC in their patients than endoscopists with an absolute ADR change <1%.
