ABSTRACT
Purpose: To examine the return of patients to intravitreal injection clinic after the COVID-19 lockdown. Patients and Methods: The electronic medical records of all patients who received intravitreal injections at a tertiary care Veterans Health Administration (VHA) clinic 14 weeks post-lockdown (5/9/20-8/13/20) in Los Angeles County were reviewed. Reference groups included injection patients during the 7-week COVID-19 lockdown (3/19/20-5/8/20) and a 7-week pre-pandemic period in 2019 (3/19/19-5/8/19). Clinic volume was compared using a one-way ANOVA. Demographic data, medical and psychiatric co-morbidities, injection diagnoses, visual acuities, and clinic volumes were compared between the 3 periods using a generalized estimating equation multivariate analysis. Results: The post-lockdown period group averaged 25.1 visits per week, compared with 12.3/week during lockdown and 25.4/week pre-COVID in intravitreal injection clinic. In the post-lockdown period, the VHA injection clinic returned closer to the pre-lockdown volume compared to the VHA comprehensive clinic (98.9% vs 57.4%, p < 0.001). Post-lockdown, COPD patients and organ transplant patients were less likely to receive injections compared to 2019 (OR 0.76 p = 0.008, OR 1.37 p < 0.0001, respectively). Patients with a diagnosis of cancer increased in proportion between the pre-pandemic and the post-lockdown periods (OR 1.31, p = 0.007). No differences were found, according to psychiatric co-morbidities. After lockdown, the proportion of patients receiving injections for diabetic macular edema (DME) increased (OR 1.11, p = 0.01). Conclusion: Injection volume returned to pre-pandemic levels immediately after lockdown ended. However, patients with high-risk comorbidities did not return to intravitreal injection clinic post-lockdown. These results can inform medical organizations, which groups may need increased safety measures and targeted outreach to address their ophthalmic needs.
ABSTRACT
PURPOSE: Early on in the COVID-19 pandemic, it was difficult to know what factors would affect patient and physician decision-making regarding ophthalmic care utilization. The purpose of this study is to investigate the effect of non-ophthalmic factors on patient decision-making to receive intravitreal injections during the COVID-19 lockdown. PATIENTS AND METHODS: Data on patients who had intravitreal injection appointments at a tertiary care Veterans Health Administration clinic during a seven-week period (March 19, 2020-May 8, 2020) of the COVID-19 outbreak in Los Angeles County were collected and compared to patients who had intravitreal injection appointments during the same time period in 2019. Demographic characteristics, injection diagnoses, visual acuities, body mass indices, co-morbidities, and psychiatric conditions of patients and clinic volumes were tabulated and compared between the two time periods. RESULTS: There were 86 patients in the injection clinic in 2020 compared to 176 patients in 2019. The mean age and gender of patients in the injection clinic did not differ between 2019 and 2020. Compared to 2019, the number of patients who identified as Hispanic or Latino remained nearly the same, but the number of patients who identified as White, Black, or Asian or Pacific Islander decreased by nearly half. In 2020, a greater proportion of patients came to the injection clinic for neovascular age-related macular degeneration (56.5% vs 39.3%, p=0.017), but a decreased proportion of patients diagnosed with a heart condition (OR 0.57, 95% CI 0.33, 0.96), chronic obstructive pulmonary disease (OR 0.43, 95% CI 0.21, 0.91), or asthma (OR 0.09, 95% CI 0.01, 0.70) came to the injection clinic. CONCLUSION: The COVID-19 pandemic was associated with behavioral changes in eyecare utilization influenced by race and systemic co-morbidities. These data can be used to design and implement strategies to address disparities in essential ophthalmic care among vulnerable populations.
