Development and validation of a video-based cold snare polypectomy assessment tool (with videos).

BACKGROUND AND AIMS: Polyps <1 cm are the most commonly found polyps during colonoscopy. Cold snare removal is preferred given the significantly higher rate of incomplete resection associated with piecemeal biopsy forceps resection. There are currently no standardized tools to assess competence in cold snare polypectomy. This study aimed to develop and validate a cold snare polypectomy assessment tool (CSPAT). METHODS: Experts in cold snare polypectomy used a Delphi method to develop the CSPAT. Metrics with a greater than 85% agreement as being "important" or "very important" were included in the CSPAT. The tool included evaluation of polyp inspection, positioning, appropriate ensnarement of tissue to ensure a rim of normal tissue, tissue retrieval, and postpolypectomy site inspection. Experts in cold snare polypectomy used the CSPAT to evaluate preselected videos that were previously evaluated using the Direct Observation of Polypectomy Skills (DOPyS) tool. Interobserver agreement was evaluated. CSPAT scores were compared with DOPyS scores to assess content validity. RESULTS: Sixteen experts developed the 12-item CSPAT, and 13 experts reviewed 55 videos. There was a moderate degree of agreement in 10 metrics (κ = .52-.59) and a substantial degree of agreement (κ = .61-.63) in the other 2. There was a strong correlation between the mean of individual metrics 1 to 12 compared with the global competence assessment (ρ = .88, P < .001). There was a moderate correlation between the average overall DOPyS score and the overall CSPAT competence score (ρ = .56, P < .001). CONCLUSIONS: We have developed and validated a customized CSPAT that can be easily applied to video-based assessments to assess competence in training and among practicing endoscopists.

Predictors of Patient Participation and Completion of Home-Based Cardiac Rehabilitation in the Veterans Health Administration for Patients With Coronary Heart Disease.

Traditional, facility-based cardiac rehabilitation (CR) is vastly underutilized in the United States. The Veterans Health Administration (VA) has developed new home-based cardiac rehabilitation (HBCR) programs to address this issue. However, the characteristics of patients who choose HBCR are unknown. We sought to determine predictors of participation and completion of HBCR at the San Francisco VA (SFVA). We evaluated patients hospitalized for ischemic heart disease between 2013 and 2016 at SFVA. Logistic regression models were used to identify predictors of participation and completion of HBCR. In 724 patients with ischemic heart disease who were eligible for CR between 2013 and 2016, 314 (43%) enrolled in HBCR. Older age was associated with lower odds of participation in HBCR (odds ratio [OR] 0.84; p <0.01). Additionally, patients with coronary artery bypass grafting (CABG) were twice as likely as those with percutaneous coronary intervention to participate in HBCR (OR 2.03; 95% confidence interval 1.40, 2.97). In HBCR participants, 48% (150/314) completed ≥9 sessions. Patients with CABG were twice as likely as those with percutaneous coronary intervention to complete the HBCR program (OR 2.02; 95% confidence interval 1.18, 3.44). There were no differences in participation or completion rates by gender, race, ethnicity, or rurality. Our study showed that the SFVAMC HCBR program achieved a 43% participation rate, well above the VA average of 13%. There were no disparities by gender, race, or rurality in terms of participation and adherence. CABG as the indication for CR was the most significant predictor of participation and completion of HBCR.
