Abstract:
Background: Data on the economic burden of long-COVID are scarce. We aimed to examine the prevalence and medical-costs for treating long-COVID.
Methods: We conducted this historical-cohort study using data of patients with COVID-19 among members of a large health-provider in Israel. Cases were defined according to physician diagnosis (definite long-COVID) or suggestive symptoms given ≥4-weeks from infection (probable cases). Healthcare resource utilization (HCRU) and direct healthcare costs (HCCs) in the period prior to infection and afterwards were compared across study groups.
Findings: Between March 2020, and March 2021, a total of 180,759 COVID-19 patients (mean[SD] age=32.9y [19.0y]; 89,665 [49.6%] females) were identified. Overall, 14,088(7.8%) individuals developed long-COVID (mean[SD] age=40.0y [19.0y]; 52.4% females). Among them, 1,477(10.5%) were definite long-COVID and 12,611(89.5%) were defined as probable long-COVID. Long-COVID was associated with age (AOR=1.058 per year, 95%CI:1.053-1.063), female sex (AOR=1.138;1.098-1.180), smoking (AOR=1.532;1.358-1.727), and symptomatic acute-phase (AOR=1.178;1.133-1.224), primarily muscle-pain and cough. Hypertension was an important risk factor for long-COVID among younger adults. Compared to non-long-COVID patients, definite and probable cases were associated with AORs of 2.47(2.22-2.75) and 1.76(1.68-1.84) for post-COVID hospitalization, respectively. While among non-long COVID patients HCCs decreased from US$ 1400 during 4 months before the infection to US$ 1021, among long-COVID patients HCC increased from $US 2435 to $US 2810.
Interpretation: Long-COVID is associated with a substantial increase in healthcare services utilization and direct-medical costs. Our findings underline the need for timely planning and allocating resources for long-COVID patient-centered care as well as for its secondary-prevention in high-risk patients.
