Indoor environmental exposures are detrimental to health outcomes and contribute to childhood morbidity; however, addressing these exposures remains a challenge in pediatric care. To mitigate morbidity associated with poor housing conditions, interventions using community health workers, mobility experiments relocating families, and medical-legal partnerships have proven successful. However, these interventions are often constrained by availability of funding, resources, and time. Using physician-generated letters is 1 strategy applied in medical-legal partnerships that does not require additional funding or resources. In this study, we examined the association between physician-generated housing letters and improvement of poor housing conditions.
