Observational vignette study to examine patient and healthcare provider perceived impact of asthma-related exacerbations in the US

Abstract

Background: Little is known about how patients and healthcare providers (HCPs) perceive the impact of asthmarelated exacerbations. This study examined the impact of asthma-related exacerbations on patients’ lives from these different perspectives. Methods: Web-based surveys were administered to a US sample of adult patients with asthma, and HCPs. Participants reviewed six vignettes describing two hypothetical patients with asthma (25-year-old/single/unemployed/ no dependents; and 45-year-old/married/employed/two young children) experiencing mild, moderate, or severe exacerbations and rated the impact on eight measures: EuroQoL-5 Dimensions (mobility, self-care, usual activities, pain/ discomfort, and anxiety/depression), sleep, household costs, and medical costs. The proportions reporting impact for each measure were calculated for each vignette; and patient responses were compared with HCP responses. Results: 302 patients with asthma and 300 HCPs completed the survey. As exacerbation severity increased, a higher proportion of patients and HCPs reported impact of exacerbations on patients with asthma. Compared with HCPs, a greater proportion of patients reported problems with pain/discomfort related to mild and moderate exacerbations. Compared with patients, HCPs were more likely to indicate sleep impact, mobility problems, and financial burden across all exacerbation severity levels; self-care problems with moderate and severe exacerbations; and problems with usual activities and anxiety/depression for severe exacerbations. Conclusions: Understanding the distinctions between how patients and HCPs perceive the impact of exacerbations is important for optimizing patient care. HCPs may be less aware of patient’s concerns about exacerbation-related pain/ discomfort. Studies are needed to further understand patient-HCP interactions regarding asthma-related exacerbations.
