Racial and ethnic disparities in ED use among older adults with asthma and primary care nurse practitioner work environments.

ABSTRACT

Background: Nurse practitioners (NPs) increasingly deliver primary care in the United States. Yet, poor working conditions strain NP care. We examined whether racial/ethnic health disparities in ED visits among older adults with asthma are moderated by primary care NP work environments. Methods: Survey data on NP work environments in six states were collected from 1,244 NPs in 2018-2019. 2018 Medicare claims data from 46,658 patients with asthma was merged with survey data to assess the associations of all-cause and ambulatory care sensitive conditions (ACSC) ED visits with NP work environment and race/ethnicity using logistic regression. Results: NP work environment moderated the association of race (Black patients versus White patients) with all-cause (odds ratio [OR] 0.91; p-value = 0.045) and ACSC (OR 0.90; p-value = 0.033) ED visits. Conclusions: Disparities in ED visits between Black and White patients with asthma decrease when these patients receive care in care clinics with favorable NP work environments.
