Importance
Long-term health effects have been indicated following COVID-19; however, the impact of COVID-19 on health-related quality of life (HRQOL), including who may experience ongoing symptoms, is unknown.
Objective
To identify change in HRQOL following COVID-19 compared to pre-infection HRQOL and a matched control group, and identify predictors of patients who worsen.
Design
Retrospective pre-post cohort study with a matched control group.
Setting
Large healthcare system in northeast Ohio.
Participants
A total of 3,690 adult patients diagnosed with COVID-19 who completed HRQOL surveys during routine care for ambulatory visits before and after infection. Propensity-score 1:1 match was utilized to identify controls without COVID who completed HRQOL at two time points.
Main Outcomes
HRQOL was assessed with PROMIS Global Health: global mental and physical health summary scores. Pre- and post-COVID PROMIS Global Health was completed as part of routine care from 1/1/2019 to 2/29/2020 and 4/4/2020 to 11/1/2021, respectively, and extracted from the electronic health record.
Results
COVID-19 patients (mean age 53±15; 66% female) completed PROMIS Global Health in the year prior (median 11.1 months) and after diagnosis (median 7.8 months). Compared to before infection, COVID-19 patients had a significant reduction in global mental health and stable global physical health (−0.85 and 0.05 T-score points, respectively) with clinically meaningful reduction (≥5 T-score points) experienced by 27% and 23% of patients, respectively. Predictors of worsening global health included being female, having depression, being hospitalized for COVID-19, and better pre-COVID global health. Compared to the control group, there was significantly worse global mental and physical health decline following COVID-19 (−0.53 and −0.37 T-score points, respectively).
Conclusions and Relevance
A quarter of patients with COVID-19 experienced meaningful reductions in HRQOL. Reductions in global mental and physical health were modest, although significantly worse than a control group. Additionally, identified predictors of patients who worsen may assist clinicians when counseling patients of their risk of worse HRQOL following COVID-19.
