Overall, both confidence and comfort level working with residents who were at risk, confirmed, or suspected of having COVID-19 increased after participating in the ECHO sessions (effect sizes≥0.7, Wilcoxon signed rank P<.001). Participants also reported impact on intent to change behavior, resident care, and knowledge sharing. The results demonstrate that ECHO COE-LTC COVID 19 effectively delivered time-sensitive information and best practices to support LTC teams and residents. It may be a critical platform during this pandemic and in future crises to deliver just-in-time learning during periods of constantly changing information.

To examine the relationship between post-acute care (PAC) quality improvement and long-term care (LTC) quality changes. Observational study using national nursing home data from Nursing Home Compare linked to Brown University's LTCFocus data. Free-standing nursing homes serving PAC and LTC residents in the United States. This study used pooled cross-sectional analysis with nursing home-level data from 2005 to 2010 (12,150 unique nursing homes). We used fixed effects models to examine the association between a 1-year change in PAC quality and a 1-year change in LTC quality, with a specific focus on related care domains. Strong and positive associations were found between related PAC and LTC care domains, particularly between the PAC and LTC influenza vaccination care domains (β=0.30, P<.001) and the PAC and LTC pneumococcal vaccination care domains (β=0.55, P<.001). Meanwhile, model results showed PAC quality changes essentially had no associations with unrelated LT
