Objective: Describe the care preference changes among nursing home residents receiving proactive Advance Care Planning (ACP) conversations from health care practitioners during the COVID-19 pandemic. Design: Retrospective chart review. Setting and Participants: Nursing home residents (n ¼ 963) or their surrogate decision makers had at least 1 ACP conversation with a primary health care practitioner between April 1, 2020, and May 30, 2020, and made decisions of any changes in code status and hospitalization preferences. Methods: Health care practitioners conducted ACP conversations proactively with residents or their surrogate decision makers at 15 nursing homes in a metropolitan area of the southwestern United States between April 1, 2020, and May 30, 2020. ACP conversations reviewed code status and goals of care including Do Not Hospitalize (DNH) care preference. Resident age, gender, code status, and DNH choice before and after the ACP conversations were documented. Descriptive data analyses identified significant changes in resident care preferences before and after ACP conversations. Results: Before the most recent ACP discussion, 361 residents were full code status and the rest were Out of Hospital Do Not Resuscitate (DNR). Of the individuals with Out of Hospital DNR, 188 residents also chose DNH. After the ACP conversation, 88 residents opted to change from full code status to Out of Hospital DNR, thereby increasing the percentage of residents with Out of Hospital DNR from 63% to 72%. Almost half of the residents decided to keep or change to the DNH care option after the ACP conversation. Conclusion and Implications: Proactive ACP conversations during COVID-19 increased DNH from less than a quarter to almost half among the nursing home residents. Out of Hospital DNR increased by 9%. It is important for all health care practitioners to proactively review ACP with nursing home residents and their surrogate decision makers during a pandemic, thereby ensuring care consistent with personal goals of care and avoiding unnecessary hospitalizations.
