Impact of the COVID-19 pandemic on adult asthma-related health care utilization.
Article in The journal of allergy and clinical immunology. Global, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The coronavirus 2019 disease (COVID-19) pandemic prompted major disruptions in chronic disease self-management and health care delivery, yet its impact on adults with asthma remains poorly characterized. Objective: Our aim was to assess changes in asthma-related health care utilization among adults during the COVID-19 pandemic (2020) compared with before the pandemic (2017-2019) and after the pandemic (2021-2024) within a large, multihospital health system. Methods: We conducted a retrospective electronic health record-based study of 42,242 adults with asthma who were receiving care at Penn Medicine from 2017 to 2024. Weekly counts of 5 encounter types (refill, telemedicine, telephone/audio, outpatient, and emergency encounters) and prescriptions for short-acting β-agonists, inhaled corticosteroids, and oral corticosteroids were compared across years. Generalized linear models evaluated changes in encounter rates during the pandemic and postpandemic periods relative to prepandemic levels, stratified by key transition intervals in 2020. Results: From 2017 to 2019, adults averaged 397 weekly asthma-related visits; in 2020, this number increased to 481. During the lockdown weeks, refill and telemedicine encounters rose by 123% and 36,445%, respectively, whereas outpatient visits declined by 65%. Prescriptions for short-acting β-agonists and inhaled corticosteroids increased by 73% and 43%, respectively, whereas oral corticosteroid prescriptions decreased by 5%. Primary care visits spiked during the lockdown, whereas allergy/immunology and pulmonary encounters remained stable throughout the year. Conclusion: The COVID-19 pandemic was associated with major shifts in adult asthma care, characterized by short-term surges in primary care visits and medication refills and reductions in in-person encounters. These patterns illustrate the capacity of asthma care systems to rapidly adapt, and they highlight the need to tailor future crisis response strategies to adult patients.
