Factors Associated with Long COVID Care Documentation among VA Patients


BACKGROUND:
The World Health Organization developed a definition of post-COVID-19 condition (also referred to as long COVID) based on certain symptoms or impairments that cannot be explained by an alternative diagnosis at least three months after the onset of infection. As many as 33 post-acute sequelae of COVID-19 infection have been identified, including pulmonary, cardiovascular, and mental health disorders. However, there is limited information about which patients seek care for potential manifestations of long COVID and the extent to which practitioners document that care as management of long COVID. This retrospective cohort study examined the rates, clinical setting, and factors associated with documented receipt of COVID-19-related care three or more months after acute infection. Investigators identified 198,601 survivors of acute COVID-19 infection, who had been diagnosed in VA with a positive COVID test between February 1, 2020 and April 30, 2021. The primary outcome was documentation in VA’s electronic health record of any of four COVID-19-related ICD-10 codes in one or more VA encounters three or more months after the date of infection through December 31, 2021. Investigators also assessed sociodemographic, geographic, and clinical characteristics as well as vaccination status.

FINDINGS:

  • In this cohort, long COVID care was documented in 26,745 Veterans (14%). Factors significantly associated with long COVID care included: older age, Black or American Indian/Alaska Native race, Hispanic ethnicity, geographic region, multiple comorbidities, having documented symptoms at the time of acute infection, and requiring hospitalization or mechanical ventilation.
  • Veterans who had received both doses of mRNA vaccine at the time of COVID-19 infection (considered fully vaccinated) were less likely to have received care for long COVID.
  • There was significant variability in rates of long COVID care documentation across VISNs (11%-18%) and VAMCs (3%-41%); 16 VA facilities with dedicated clinics for long COVID follow-up had higher rates.
  • The most common outpatient clinics at which Veterans with long COVID presented were primary care and general internal medicine (33% of encounters).

IMPLICATIONS:

  • Findings should provide support and guidance for healthcare systems to develop approaches to the evaluation and management of patients who experience long COVID.

LIMITATIONS:

  • It is unclear what symptoms or manifestations might have prompted physicians to document a COVID-19-related ICD-10 code more than three months after the onset of infection.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
