Abstract
? 2021 Elsevier Inc.Background: Patients with limited English proficiency have barriers to accessing care. Rather than a binary use or no use, this study uses granular data on frequency of interpreting services to determine if this frequency is associated with differences in peri-operative length of stay for patients with limited English proficiency. Materials and Methods: This is a cross sectional study on length of stay for peri-operative admissions of at least one night during 2018, for patients who used medical interpreting services in an academic medical center in Boston, Massachusetts. The participants are split into quartiles of ascending number of interpreting events per day. The exposure for the primary outcome is the frequency of interpreting events per day during peri-operative admission. The primary study outcome measurement is peri-operative length of stay in days. Results: There was a statistically significant decrease in length of stay for patients in the highest two quartiles of interpreting service frequency, compared to the lowest quartile: quartile 2 trended shorter by 1.4 d (95% CI -4.5 to 1.7, P = 0.37), quartile 3 was 4.2 d shorter (95% CI -7.6 to -0.7, P = 0.02), and quartile 4 was 4.6 d shorter (95% CI -8.1 to -1.1, P = 0.01). Conclusions: More frequent interpreting services per day during peri-operative admission are associated with shorter length of stay in adjusted analysis. The findings merit further study in an intervention to increase use of interpreting services for surgical patients with limited English proficiency to study the impact of increased frequency of culturally competent care.
