Clinical characteristics and symptom duration among outpatients with COVID-19.


ABSTRACT:

Background

Approximately 80% of people with COVID-19 do not require hospitalization. Studies examining the outpatient experience have not tracked symptoms to resolution leading to unknown expected symptom duration. Our objectives were to (1) determine symptom duration among patients with COVID-19 who do not require hospitalization and (2) identify potential risk factors associated with prolonged symptom duration.

Design

This is a retrospective cohort study conducted across an academic healthcare system including adult patients with laboratory-confirmed SARS-CoV-2 infection between March 18th and April 28th, 2020 who were not hospitalized. Symptom duration encompassed time from patient-reported symptom onset as documented in the chart until documented symptom resolution. We calculated the median symptom duration and tested if demographics, comorbidities, or reported symptoms were associated with symptom duration.

Key results

Of 294 patients meeting inclusion criteria, 178 (60.5%) had documented symptom resolution. The median [interquartile range (IQR)] symptom duration for included patients was 15 (8-24) days. No associations were found between comorbidities and symptom duration. Factors associated with prolonged symptom duration were presence vs lack of lower respiratory symptoms [median (IQR) 16.5 (10.75-33.5) vs 14.5 (7-21.75) days respectively, P < .001] and neurologic symptoms [median (IQR) 17 (9-28) vs 9.5 (4-17) days, P < .001] at disease onset.

Conclusions

The median symptom duration in outpatients is 15 days and over 25% of patients have symptoms longer than 21 days.
