Exploring Factors Contributing to Chronic Obstructive Pulmonary Disease (COPD) Guideline Non-Adherence and Potential...

Acute exacerbations of chronic obstructive pulmonary disease (COPD) have a significant and prolonged impact on health-related quality of life, patient outcomes, and escalation of pulmonary function decline. COPD-X guidelines published in 2003 subsist to facilitate a shift from the emphasis on pharmacological treatment to a more holistic multi-disciplinary interventions approach. Despite the existing comprehensive recommendations, readmission rates have increased in the last decade. Evidence to date has reported sub-optimal COPD guidelines adherence in emergency departments. This qualitative study explored contributing factors to interdisciplinary staff non-adherence and utilisation of COPD-X guidelines in a major Southern Queensland Emergency Department.

Semi-structured qualitative interviews with interdisciplinary staff were conducted in an emergency department. A purposive sample of doctors, nurses, physiotherapists, pharmacist and a social worker were recruited. Interviews were digitally recorded, de-identified and transcribed verbatim. Data analysis followed a coding process against the Theoretical Domains Framework (TDF) to examine implementation barriers and potential solutions. Identified factors affecting non-adherence and underutilisation of guidelines were then mapped to the capability, opportunity, motivation, behaviour model (COM-B) and behaviour change wheel (BCW) to inform future implementation recommendations.

Prominent barriers influencing the clinical uptake of COPD guidelines were identified using TDF analysis and included knowledge, professional role clarity, clinical behaviour regulation, memory, attention, and decision process, beliefs about departmental capabilities, environmental context and resources. Potential interventions included education, training, staffing, funding and time-efficient digitalised referrals and systems management reminders to prevent COPD readmissions, remissions and improve patient health-related quality of life.

Implementation strategies such as electronic interdisciplinary COPD proforma that facilitates a multimodal approach with appropriate patient/staff resources and referrals prior to discharge from an ED require further exploration. Greater clarity around which components of the COPD X guidelines must be applied in ED settings needs to stem from future research.
