Global payment contract attitudes and comprehension among internal medicine physicians

Global payment contracts (GPCs) are increasingly common agreements between insurance payers and healthcare providers that incorporate aspects of risk adjustment, capitation, and pay-for-performance. Physicians are often viewed as potential barriers to implementation of organizational change, but little is known about internist opinion on GPC involvement or specific internist attributes that might predict GPC support. We aimed to investigate internist and internal medicine subspecialist support of GPC involvement, and to identify associations among physician attributes, GPC knowledge, and GPC support.

Cross-sectional.

General medicine and internal medicine subspecialist physicians within the Beth Israel Deaconess Department of Medicine in Boston, Massachusetts, were surveyed 4 years after care organization entry into a GPC. Measurements collected included reported support for GPC involvement, reason for support, and demonstrated comprehension of key GPC details.

Of the 281 respondents (49% response rate), 85% reported supporting involvement in a GPC. In a multivariate ordinal logistic regression model, exposure to prior information about GPCs, demonstrated comprehension of key GPC details, longer time since completion of residency, and lower clinical time commitment were all independently associated with higher levels of GPC involvement support.

Four years since first engaging in a global payment contract, a majority of internal medicine physician respondents support this decision. Understanding predictors of physician support for GPC involvement within our care organization may help other health systems to approach organizational change. Health system leaders debating GPC involvement should consider engaging physicians via educational interventions geared toward improving GPC support.
