Matthew Bishop: "Regarding COVID-19, I am deeply concerned that a lack of standardized housing data in the EMR to identify patients that are homeless is preventing: (a) early detection of symptoms before diagnosis, which could lead to quarantine (b) care transitions for patients returning to shelter who may need to be quarantined in some type of facility outside of the shelter, (c) trends in COVID-19 transmission that could influence broader public health policies (e.g. shutdown of public transit), (d) clear communication on how homeless people are supposed to "shelter in place" when they don't have shelter. Are there efforts underway nationally to more systematically use existing HUD/HIMS data and linking it to EMR data to inform COVID-19 response?"
