The Significance of Asthma Follow-Up Consultations for Adherence to Asthma Medication, Asthma Medication Beliefs, and Asthma Control

Abstract EN

Objective.

The aim was to investigate adherence to asthma medication treatment, medication beliefs, and asthma control in relation to asthma follow-up consultations in asthmatics in the general population.

A further aim was to describe associations between adherence, medication beliefs, and asthma control.

Method.

In the population-based West Sweden Asthma Study, data allowing calculation of adherence for 4.5 years based on pharmacy records were obtained from 165 adult asthmatics.

Additional data were collected through questionnaires and structured interviews.

Results.

The mean adherence value for filled prescriptions for regular asthma medication was 68% (median 55.3%) but varied over the year under study.

Adherence to combination inhalers with corticosteroids and long-acting beta2 agonists was higher than adherence to single inhalers with corticosteroids only.

More than one-third of participants reported not having seen an asthma nurse or physician for several years.

Regular asthma follow-up consultations were associated with both higher adherence and the belief that asthma medication was necessary but were not associated with asthma control.

Conclusions.

Adherence to asthma medication treatment was low and varied over the year under study.

The current study suggests that quality improvements in asthma care are needed if adherence to asthma medication is to be improved.
