Abstract
Objective
We examined whether cataract surgery utilization and preoperative visual acuity were associated with patient-specific factors, including ocular findings and comorbidities, general biomedical factors, and/or sociodemographic factors.
Design
Retrospective, cross-sectional study.
Subjects, Participants, and/or Controls
We reviewed the electronic health records of patients from 2012 to 2022 who were examined and followed for at least 2 years by an eye care provider at University of California San Francisco Health (UCSF Health) and who had cataract in at least one eye associated with best-corrected visual acuity of 20/25 or worse. Data include ocular factors (e.g., best-corrected visual acuity, lens opacity grade, diagnoses of glaucoma, and/or age-related macular degeneration), biomedical comorbidities, and sociodemographic factors including race/ethnicity, health insurance coverage, primary language spoken, and social vulnerability index.
Methods
Logistic and multivariate regression analyses.
Main Outcome Measures
We examined cataract surgery utilization and preoperative best-corrected visual acuity.
Results
Compared to White and Asian patients, Black patients had the lowest rates of cataract surgery utilization and the poorest mean preoperative visual acuities, with Hispanic patients following in second place in both categories. However, when the analysis controlled for sociodemographic and biomedical factors, Medicaid insurance and speaking Chinese as a primary language emerged as significant associations. In addition, higher cataract surgery utilization rates were associated with worse preoperative best-corrected visual acuity, a concurrent diagnosis of glaucoma, and a concurrent diagnosis of macular degeneration. Worse preoperative visual acuity was associated with Spanish or Chinese language preference, Medicaid status, and glaucoma diagnosis; poorer preoperative visual acuity was only weakly correlated with increased social vulnerability.
Conclusions
After adjusting for other biomedical and sociodemographic variables, having Medicaid insurance and being a non-English speaker were the factors most notably associated with reduced cataract surgery utilization and poorer preoperative visual acuity. Health insurance and language barriers, as well as other biomedical and sociodemographic factors, may explain a large proportion of the racial disparities in both cataract surgery utilization and preoperative visual acuity observed among Black and Hispanic patients. Chinese-speaking patients with limited English proficiency are a vulnerable subgroup that exhibits lower rates of cataract surgery utilization and higher degrees of visual loss prior to undergoing cataract surgery compared to other Asian patients.
