Physical function and fatigue recovery at 6 months after hospitalization for COVID-19.

ABSTRACT

INTRODUCTION: There are an increasing number of individuals with long-term symptoms of coronavirus-19 disease (COVID-19); however, the prognosis for recovery of physical function and fatigue after COVID-19 is uncertain. OBJECTIVE: To report the changes in functional recovery between 1 and 6 months after hospitalization of adults hospitalized for COVID-19 and explore the baseline factors associated with physical function recovery. DESIGN: A prospective cohort study. SETTING: Tertiary care hospital. PARTICIPANTS: U.S. adult COVID-19 survivors. INTERVENTION N/A. MAIN OUTCOME MEASURES: Telephone interviews assessed three outcome domains basic and instrumental activities of daily living (ADLs) performance, fatigue, and general physical function (Health Assessment Questionnaire [HAQ]). RESULTS: The age of participants (n = 92) ranged from 22 to 95 years (54.3 ± 17.2). Across outcome domains, a majority (63%-67%) of participants developed new ADL impairment, fatigue, or worsening HAQ severity by 1 month. Of those, 50%-79% partially or fully recovered by 6 months, but 21%-50% did not recover at least partially. Fifteen to 30% developed new impairment between 1 and 6 months. For those without any improvement in ADL impairments at 6 months, lower socioeconomic status was significantly more common (p = .01) and age ≥ 65 (p = .06), trending toward being more common. CONCLUSION: In this cohort, a substantial proportion of the participants who developed new ADL impairment, worsening fatigue, or HAQ severity after hospitalization for COVID-19 did not recover at least partially by 6 months after discharge. Evaluating functional status 1 month after discharge may be important in understanding functional prognosis and recovery after hospitalization for COVID-19.
