Do patients with asthma fill their prescriptions? A primary compliance study

Area of Science:

• Pulmonary Medicine
• Health Services Research
• Patient Adherence Studies

Background:

• Asthma management requires consistent adherence to prescribed treatments.
• Primary noncompliance, the failure to obtain medication after prescription, is a significant barrier to effective asthma control.
• Understanding factors influencing primary noncompliance is crucial for reducing asthma-related morbidity.

Purpose of the Study:

• To investigate the rate and predictors of primary noncompliance in asthma patients.
• To identify patient groups at higher risk for not filling asthma prescriptions.

Main Methods:

• A prospective study involving matching prescriptions written by general practitioners (GPs) with dispensed medications for asthma patients.
• Data collected over a 3-month period in a rural setting.
• Analysis included relative risk calculations for factors such as asthma severity, socioeconomic status, gender, and age.

Main Results:

• A primary noncompliance rate of 30% was observed, with 251 out of 359 prescriptions dispensed.
• Mild asthmatics had a lower risk of noncompliance (RR=0.81) compared to severe asthmatics.
• Patients of lower and medium socioeconomic status showed decreased odds of filling prescriptions (RR=0.84) compared to high socioeconomic status patients.
• Neither gender nor age influenced primary compliance.

Conclusions:

• High primary noncompliance is a significant issue in asthma care, contributing to patient morbidity.
• General practitioners should enhance patient counseling on the necessity of asthma treatment, not just its correct usage.
• Targeted, intensive counseling may be beneficial for patients with mild to moderate asthma and those from lower socioeconomic backgrounds.
