A tool for recognizing asthma nonadherence during disease management: A prospective cohort study

Area of Science:

• Pulmonary Medicine
• Clinical Pharmacy
• Health Outcomes Research

Background:

• Asthma patient adherence is a critical challenge, with a notable lack of rapid identification tools for nonadherence.
• Nonadherence significantly impacts asthma management and patient outcomes.

Purpose of the Study:

• To develop and validate a simple, rapid screening tool for identifying nonadherent asthma patients.
• To assess the predictive accuracy of the Tool for Recognizing Asthma Nonadherence (TRAN) for identifying nonadherence.

Main Methods:

• The study utilized data from a multicenter, prospective cohort of asthma patients.
• The Tool for Recognizing Asthma Nonadherence (TRAN) was developed as a ratio of perceived health (VAS) to asthma control test score.
• TRAN was validated against the Medication Adherence Report Scale for Asthma (MARS-A) in development and validation sets.

Main Results:

• TRAN demonstrated strong predictive value for nonadherence (OR=9.14, P<0.01) in the development set (n=518).
• The area under the curve (AUC) for TRAN was 0.810 in the development set and 0.75 in the validation set (n=175).
• At a cutoff of 1.08, TRAN achieved 82.0% sensitivity and 84.4% specificity for identifying nonadherence.

Conclusions:

• The Tool for Recognizing Asthma Nonadherence (TRAN) is a simple and effective method for initial screening of asthma patients.
• TRAN facilitates the early identification of patients at risk for nonadherence, enabling timely interventions.
