Medical Costs, Health Care Utilization, and Productivity Losses Associated with Hypertension Moderated by COVID-19 Diagnosis Among US Commercial Enrollees.

Background: Hypertension is a major risk factor for cardiovascular and renal diseases, significantly contributing to morbidity and mortality. The COVID-19 pandemic has heightened concerns about the impact of hypertension on severe COVID-19 outcomes.

Methods: We analyzed 2020-2021 data from the MarketScan Commercial and Health and Productivity Management databases, focusing on adults aged 18-64 years with continuous employer-sponsored private insurance, excluding pregnancy or capitated plans. We compared medical costs, healthcare utilization (emergency department [ED] visits, inpatient admissions, outpatient visits, and outpatient prescription drugs), and productivity losses (sick absences, short-term disability [STD], and long-term disability [LTD]) between individuals with and without hypertension, stratified by COVID-19 diagnosis. We used multivariable regression models, including an interaction term for hypertension and COVID-19 diagnosis, to estimate differences in outcomes, adjusting for demographics and comorbidities.

Results: Among 1,296,596 adults, 21% had hypertension. Those with hypertension were older, less likely female, less likely urban residents, and had more comorbidities. Excess medical costs associated with hypertension were $8,572 per patient over the two-year period (95% CI $8,182-$8,962). Patients with versus without hypertension had 0.200 (95% CI, 0.195-0.205) more ED visits, 0.081 (95% CI, 0.077-0.085) more inpatient admissions, 5.984 (95% CI, 5.892-6.075) more outpatient visits, and 20.25 (95% CI, 20.09-20.41) more prescriptions per patient over the two-year period. They also had more sick absences (1.13 days; 95% CI 0.93-1.34) and STD occurrences (3.88 days; 95% CI 3.56-4.20) per patient. Among those with hypertension, individuals with versus without COVID-19 had $3,495 (95% CI, $2,135-$4,856) higher medical costs and 2.588 (95% CI, 1.112-4.065) more STD days per patient over the two-year period.

Conclusions: Hypertension was associated with higher medical costs, healthcare utilization, and productivity losses, exacerbated by COVID-19.
