Despite evidence that social factors can result in poor health outcomes, and the emergence of payment models that encourage the use non-medical interventions to improve health, many health care providers do not identify the social determinants of health within patient populations through routine screening. This Article explores the possible reasons for this inconsistency by considering screening practices in medical-legal partnerships (MLPs), the health care approach most concerned with identifying and treating the social determinants of health. Through an analysis of the results of a national survey and qualitative interviews with MLPs, we discovered that screening is not operationalized or consistent within many MLPs. We conclude that although health care providers may recognize the value of screening, they are not yet embracing the practice, perhaps because of an unspoken fear that fulsome screening identifies so many unmet social and legal needs that community-based resources cannot satisfy demand. This fear is unfounded. Approaches such as MLP demonstrate that social and legal needs can be efficiently treated through collaboration with other professionals, often within the health care setting. Nevertheless, providers must first operationalize screening to truly understand the scope of the need in their patient populations and collaborate to address those needs.
