Determinants of referral network size for screening colonoscopies in the Veterans Health Administration after the implementation of the MISSION Act.

ABSTRACT:

Objective

To measure key characteristics of the Veterans Health Administration's (VHA) Community Care (CC) referral network for screening colonoscopy and identify market and institutional factors associated with network size.

Data sources

VHA electronic health records, CC claim data, and National Plan and Provider Enumeration System.

Study design

In this retrospective cross-sectional study, we measure the size of the VHA's CC referral networks over time and by VHA parent facility (n = 137). We used a multivariable linear regression to identify factors associated with network size at the market-year level. Network size was measured as the number of physicians who performed at least one VHA-purchased screening colonoscopy per 1000 enrollees at baseline.
