Abstract

Introduction: We report the COVID-19 pandemic's impact on health-care use disruption among people with mild cognitive impairment or Alzheimer's disease and related dementia (MCI/ADRD). Methods: We compared the pandemic-period health-care use between MCI/ADRD and matched non-MCI/ADRD patients. Using 4-year pre-pandemic data, we modeled three health-care use types (inpatient, outpatient, emergency encounters) to predict pandemic-period use, disaggregated for lockdown and post-lockdown periods. Observed health-care use was compared to the predicted. Proportional differences (confidence intervals) are reported. Results: Both MCI/ADRD and non-MCI/ADRD patients (n = 5479 each) experienced pandemic-related health-care use disruptions, which were significantly larger for the MCI/ADRD group for outpatient, –13.2% (–16.2%, –10.2%), and inpatient encounters, –12.8% (–18.4%, –7.3%). Large health-care disruptions during lockdown were similar for both groups. However, post-lockdown outpatient, –14.4% (–17.3%, –11.5%), and inpatient, –15.2% (–21.0%, –9.5%), disruptions were significantly greater for MCI/ADRD patients. Conclusion: MCI/ADRD patients experienced greater and sustained pandemic-related health-care use disruptions, highlighting the need for robust strategies to sustain their essential health care during pandemic-like catastrophes.
