Barriers and enablers to medicine-taking behaviours in chronic obstructive pulmonary disease: a qualitative interview study.

BACKGROUND

Chronic Obstructive Pulmonary Disease (COPD) is associated with low health-related quality of life and high costs to healthcare systems, particularly due to hospital admissions and exacerbations. Medicines, inhalers especially, reduce the risk of hospitalisations and exacerbations, but factors influencing medicine-taking behaviours are not fully understood.

AIM

To explore experiences of people with COPD related to medicines, and followingly identify and characterise any barriers and enablers related to medicine-taking behaviours using the Theoretical Domains Framework (TDF).

METHOD

Semi-structured qualitative interviews were conducted and included ten people with COPD who had previously been admitted to hospital. Systematic text condensation was used inductively in the primary analysis of the interviews. In the secondary analysis, meaning units from the primary analysis were mapped to the TDF and summarised as barriers and enablers.

RESULTS

Five major themes were developed in the primary analysis: (1) health literacy and information needs, (2) patient autonomy, (3) lack of access to medicines, (4) lack of effect from medicines, and (5) experiences of medicines-related issues. In the secondary analysis, thirteen barriers and nine enablers were mapped to nine out of the fourteen domains of the TDF.

CONCLUSION

People with COPD experience challenges related to medicines which need to be addressed by researchers and healthcare providers. The identified barriers and enablers mapped to the TDF can guide and inform future design of interventions and health care services.
