Abstract
Background: The Work-related Asthma (WRA) Screening Questionnaire (Long-Version)(WRASQ-L)TM is a screening questionnaire that could improve recognition of WRA.
Objective: To conduct a definitive evaluation of the WRASQ-LTM to justify its implementation in clinical settings.
Methods: Employed adults aged 18-75 years with asthma confirmed by objective measures and the ability to take time off work were eligible. Participants completed the WRASQ-LTM then monitored their peak expiratory flow at and away from work or completed a specific inhalation challenge test. Data were classified as WRA or non-WRA by two asthma specialists, blinded to WRASQ-LTM answers. Sensitivity (SN), specificity (SP), positive and negative predictive values (PPV and NPV, respectively) and Youden's index were calculated for cut-offs of a positive screen.
Results: Of 106 participants (47.1±7.1 years (mean ± SD); 60 (57%) female), 14 (17%) were classified as WRA and were significantly younger in age than non-WRA participants (p=0.043). The questionnaire has high SN and NPV (90.9% and 93.1%, respectively), but low PPV and SP (32.1% and 26.0%, respectively).
Conclusions: The WRASQ-LTM has high SN and NPV. High SN is of primary interest to ensure that few false negative screens are missed and those with potential WRA are identified and continue to specialist care. The SN indicates utility of the questionnaire in clinical settings. Further benefits of the tool include its potential to prompt for education on the symptom-workplace relationship, workplace exposures, personal protective equipment use, and collect exposure and occupational history.
期刊介绍：
JACI: In Practice is an official publication of the American Academy of Allergy, Asthma & Immunology (AAAAI). It is a companion title to The Journal of Allergy and Clinical Immunology, and it aims to provide timely clinical papers, case reports, and management recommendations to clinical allergists and other physicians dealing with allergic and immunologic diseases in their practice. The mission of JACI: In Practice is to offer valid and impactful information that supports evidence-based clinical decisions in the diagnosis and management of asthma, allergies, immunologic conditions, and related diseases.
This journal publishes articles on various conditions treated by allergist-immunologists, including food allergy, respiratory disorders (such as asthma, rhinitis, nasal polyps, sinusitis, cough, ABPA, and hypersensitivity pneumonitis), drug allergy, insect sting allergy, anaphylaxis, dermatologic disorders (such as atopic dermatitis, contact dermatitis, urticaria, angioedema, and HAE), immunodeficiency, autoinflammatory syndromes, eosinophilic disorders, and mast cell disorders.
The focus of the journal is on providing cutting-edge clinical information that practitioners can use in their everyday practice or to acquire new knowledge and skills for the benefit of their patients. However, mechanistic or translational studies without immediate or near future clinical relevance, as well as animal studies, are not within the scope of the journal.
