COVID-19 outcomes among people with intellectual and developmental disability in California: The importance of type of residence and skilled nursing care needs

Background: People with intellectual and developmental disabilities (IDD) appear to be at greater risk for severe outcomes from COVID-19. The roles of congregate living and skilled nursing care needs in this disparity are unclear. Objective: To determine the impact of residential setting and level of skilled nursing care on COVID-19 outcomes for people receiving IDD services, compared to those not receiving IDD services. Methods: Utilizing publicly available California data on COVID-19 outcomes for people receiving IDD services (early May through October 2, 2020), we report outcomes based on seven types of residence, differentiated by number of residents and level of skilled nursing care provided. We compared these results to the larger California published outcomes. Results: Compared to Californians not receiving IDD services, in general, those receiving IDD services had a 60% lower case rate, but 2.8 times higher case-fatality rate. COVID-19 outcomes varied significantly among Californians receiving IDD services by type of residence and skilled nursing care needs: higher rates of diagnosis in settings with larger number of residents, higher case-fatality and mortality rates in settings that provided 24-h skilled nursing care. Conclusions: Diagnosis with COVID-19 among Californians receiving IDD services appears to be related to the number of individuals within the residence, while adverse COVID-19 outcomes were associated with level of skilled nursing care. When data is available, future research should examine whether these relationships persist even when controlling for age and pre-existing conditions. (C) 2020 Elsevier Inc. All rights reserved.

Automated summary

Individuals with IDD receiving services in California have significantly varied COVID-19 outcomes depending on their residential setting and level of skilled nursing care. While they have a lower case rate compared to those not receiving IDD services, they have a higher case-fatality rate. The study suggests that the number of individuals within the residence impacts COVID-19 diagnosis, while adverse outcomes are associated with the level of skilled nursing care provided.
