There are three major microvascular complications of diabetes, retinopathy, nephropathy, and neuropathy, among which diabetic retinopathy (DR) is the most common. Several studies suggest that the Hispanic/LatinX population exhibit the highest cases of both diabetes and DR. Strategies aimed at reducing risk factors that could minimize the likelihood of DR development or progression could be beneficial. This retrospective study assessed DR in the Hispanic/LatinX population in pharmacist-managed cardiovascular risk reduction services. A chart review was conducted for 60 individuals who visited clinics led by both a pharmacist and a primary care physician (intervention group) and 178 individuals who saw physicians only (control group). Demographics, metabolic parameters, DR severity, and pharmacist appointment data were collected. The highest benefit of pharmacist intervention was observed in terms of a greater but insignificant decrease in HbA1c; however, there was no benefit of pharmacist's intervention on DR in general, likely due to the longer duration of diabetes and higher HbA1c at the beginning of the study. When the DR progression was examined based on the frequency of pharmacy visits, individuals who met a pharmacist more than two times per year showed more stable and lesser worsening of DR. Overall, our studies suggest that pharmacist intervention could benefit retinopathy outcome; however, well-known determinants of DR such as good glycemic control and duration of diabetes still play a critical role, in addition to challenges in receiving healthcare by the Hispanic/LatinX population. Future strategies in a prospective manner could help retinopathy outcomes in these at-risk patient populations.
