Abstract

Introduction

Atopic dermatitis (AD) is associated with risk factors for venous thromboembolism (VTE). However, the risk of VTE among this population is unknown. The aim of this study was to assess the risk of VTE among adults with AD and compare the risk vs. matched non-AD controls.

Methods

This retrospective study used claims data from the IBM Watson MarketScan® Commercial Claims and Encounters, Medicare Supplemental, and Medicaid databases to identify adults aged 18 years or older with AD. Incidence rates (IR) per 100 person-years (PY) of VTE were reported for three cohorts: overall AD, moderate-to-severe AD, and non-AD controls matched by age, sex, and calendar time to the overall cohort. Cox proportional hazards regression was used to estimate hazard ratios (HR) for VTE risk.

Results

Overall, 198,685 patients with AD were identified. Crude VTE IRs were 0.24 for AD overall, 0.31 for moderate-to-severe AD, and 0.25 for non-AD controls. VTE risk was similar in patients with AD vs. non-AD controls (partially adjusted HR 1.00, 95% confidence interval [CI] 0.92, 1.09). VTE risk was greater in patients with moderate-to-severe AD vs. non-AD controls in partially adjusted models (HR 1.24, 95% CI 1.13, 1.36), but not after adjustment for healthcare use and VTE risk factors (HR 0.95, 95% CI 0.85, 1.07).

Conclusions

AD was not an independent risk factor for VTE, and the risk of VTE among patients with AD was low. These findings provide valuable context for understanding VTE risk among patients with AD, which is particularly relevant as advanced therapies for the treatment of moderate to severe AD, such as janus kinase inhibitors, become available.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
