Legal, geographic and organizational contexts that shape knowledge sharing in the hospital discharge process for people experiencing homelessness in Toronto, Canada

Abstract

People experiencing homelessness use acute healthcare at higher rates than the general population, yet hospitals frequently discharge them to the streets or emergency shelters. Available literature on the hospital discharge process for people experiencing homelessness identifies knowledge sharing as an important and challenging part of the discharge process; however, it does little to explain what generates these challenges or what might support knowledge sharing. In this study, we explain under which contexts certain mechanisms are triggered to facilitate knowledge sharing between hospitals and shelters during the discharge process. Between September 2018 and April 2019, we interviewed 33 participants: hospital workers on general medicine wards across three hospitals; shelter workers; researchers, policy advisors or advocates working at the intersection of homelessness and healthcare in Toronto. We find that within the legal context of health information protection, the concept of "circle of care" has created barriers to knowledge sharing between hospitals and shelters by excluding shelter workers from discharge planning. We note, however, that the degree to which hospital workers have navigated these barriers and brought shelter workers into the discharge process varies across hospitals. We explore this variation and find that certain geographic and organisational contexts have activated the development of institutional- and individual-level relationships between hospitals and shelters or their workers, respectively. We suggest that these relationships generate increased trust and communication and have led to knowledge sharing between hospitals and shelters. These findings are applicable in most urban centres with hospitals and where people experiencing homelessness live. Understanding the role of context is imperative for developing appropriate and effective interventions to improve hospital discharge processes. The development and implementation of more effective discharge processes can contribute to improved post-discharge care and recovery for this patient population and contribute to addressing health equity.
