Context: One of the most important possibilities of value‐based payment is its potential to spur innovation in upstream prevention, such as attention to social needs that lead to poor health. However, there is uncertainty about the conditions under which value‐based payment will encourage health care providers to innovate to address upstream social risks.
Methods: We used the 2017‐2018 National Survey of Healthcare Organizations and Systems (NSHOS), a nationally representative survey of physician practices (n = 2,178), to ascertain (1) the number of social risks for which practices systematically screen patients; (2) the extent of practices’ participation in value‐based payment models; and (3) measures of practices’ capacity for innovation. We used multivariate regression models to examine predictors of social risk screening.
Findings: On average, physician practices systematically screened for 2.4 out of 7 (34%) social risks assessed by the survey. In the fully adjusted model, implementing social risk screening was not associated with the practices’ overall exposure to value‐based payment. Being in the top quartile on any of three innovation capacity scales, however, was associated with screening for 0.95 to 1.00 additional social risk (p < 0.001 for all three results) relative to the bottom quartile. In subanalysis examining specific payment models, participating in a Medicaid accountable care organization was associated with screening for 0.37 more social risks (p = 0.015). Expecting more exposure to accountable care in the future was associated with greater social risk screening, but the effect size was small compared with practices’ capacity for innovation.
Conclusions: Our results indicate that implementation of social risk screening—an initial step in enhancing awareness of social needs in health care—is not associated with overall exposure to value‐based payment for physician practices. Expanding social risk screening by physician practices may require standardized approaches and implementation assistance to reduce the level of innovative capacity required.
