Nurse Work Environment and Hospital Readmission Disparities Between Patients With and Without Limited English Proficiency

Minimal progress has been made in narrowing disparities between patients with and without limited English proficiency (LEP). Using 2016 data from RN4CAST-US, New Jersey Discharge Data Collection System, and AHA Annual Hospital Survey, multivariable logistic regression models were employed to examine whether and to what extent the hospital nurse work environment, defined as the conditions that nurses work in, is associated with decreased disparities in 7-day hospital readmissions between patients with and without LEP. Existing literature has established associations between nurse work environments and outcomes disparities of various minoritized populations; however, no literature has examined this relationship in the context of hospitalized patients with LEP. In a sample of 424,745 hospitalized adults (n = 38,906 with LEP), patients with LEP, compared to those without LEP, were younger (63.4 vs 64 years old, p < 0.001), more likely to be insured by Medicaid (8.9% vs 5.5%) or uninsured (7.5% vs 2%, p < 0.001), and readmitted (4.5% vs 3.9%, p < 0.001). Adjusting for patient and hospital characteristics, LEP patients had 33% higher odds of a 7-day readmission, as compared to patients without LEP (OR 1.33, 95% CI [1.19-1.47]). A significant interaction was found between patients' LEP status and the nurse work environment (OR 0.83, 95% CI [0.70-0.99]), such that patients with LEP experienced lower odds of 7-day readmission in more favorable nurse work environments, compared to patients without LEP. Hospitals dedicated to providing equitable healthcare may consider enhancing nurses' working conditions as a potential way to reduce disparities in readmission rates.
