 ● Experience with decision coaching program: Provider experience with decision coaching program measured through encounter satisfaction, difficulty, and communication

Exploratory outcomes

 ● Net cost of CHW-led decision coaching program for PSA screening: cost of CHW-led decision coaching program and its effect on prostate cancer screening costs by measuring CHW program costs and healthcare utilization costs

 ● Behaviors and norms around PSA screening and perceptions of feasibility and acceptability of CHW-led decision coaching: Qualitative evaluation of patient and provider perceptions through in-depth, semi-structured interviews and other qualitative data; triangulation of mixed methods data sets from patients and provider interviews, clinical encounters, and surveys to better understand implementation.
