ABSTRACT
CDC guidelines for COVID-19 testing in March 2020 did not prioritize underserved communities. We present the effect that expanding COVID-19 testing had for residents of the predominantly Hispanic city of Chelsea, MA, which had the highest case rate in the state. Results were compared to another city with similar demographics, Lynn, MA, where testing eligibility remained unchanged. Institutional data were used to identify outpatient visits for influenza-like illness or COVID-19 exposure, COVID-19 tests, and hospitalizations for confirmed COVID-19 between 3/30/2020-4/28/2020. Multivariable logistic regressions were used to compare outcomes before and after the change in testing eligibility occurred on 4/13/2020. A total of 3,060 patients were included, 1,374 Chelsea residents and 1,686 Lynn residents. After guidelines changed, Chelsea residents were more likely to present as outpatients (adjusted odds ratio [AOR] 4.2, p < 0.001) and less likely to be hospitalized (AOR 0.2, p < 0.001). They were more likely to be tested (AOR 8.8, p < 0.001), but less likely to test positive (AOR 0.6, p = 0.05). Lynn residents were also more likely to be tested after 4/13/2020 (AOR 1.9, p < 0.001), but no significant differences in visit acuity or test positivity were observed. This study demonstrates how broadening testing eligibility for one highly affected, predominantly Hispanic community was associated with an increase in outpatient presentations and a concomitant decrease in test positivity and hospitalizations. These results highlight the impact of improved access to care on utilization of services among underserved communities, a lesson that is especially crucial as we continue to grapple with the COVID pandemic.
