Importance: In 2017, New York, New York, launched the United States' first right-to-counsel program, guaranteeing lawyers to low-income tenants in select zip codes, which was associated with reducing eviction risk by half.

Article Synopsis
  • The Affordable Care Act mandates that nonprofit hospitals report on how they assess and invest in community health needs, but the effectiveness of such reports for tracking social determinants of health, like housing, is under scrutiny.
  • A study of 47 nonprofit hospitals in 5 communities with high homelessness rates revealed that while 55% acknowledged housing as a health need, only a small percentage detailed related strategies (36%) or spending (26%).
  • There was a significant lack of alignment among the hospitals' identified needs, strategies, and spending regarding housing, indicating a need for regulatory changes to improve accountability and transparency in addressing social health issues.
