Establishing an expert opinion framework for lung volume reduction in Ireland: a Delphi consensus technique.

BACKGROUND

Lung volume reduction (LVR) is an effective treatment option offered to patients with emphysema. There is no formalised LVR referral network in Ireland. A rigorous approach to agreeing and implementing a LVR referral framework in an Irish context is required. A Delphi process was used to provide a basis for a framework of multi-disciplinary teams (MDTs) which can provide LVR as a management option. A Delphi process offers a framework for understanding variations and developing a consensus from expert opinion.

AIM

The aim of this study was to develop consensus on recommendations for LVR referral guidelines in an Irish context and provide a national scope based on current practice and evidence.

DESIGN

In accordance with Guidance on Conducting and Reporting Delphi Studies, a consensus-building Delphi study was performed. Thirty-three statements informed from review of research literature were identified and presented to participants. Evaluation of the statements was performed by an expert panel using a 5-point Likert scale. ≥ 70% agreement was defined as consensus and items with a consensus rating of < 70% were revised during the process. In total, Delphi questionnaires were distributed to 18 experts with a response rate of 78% (n = 14) and a follow-up response-rate of 50% (n = 7).

SETTING/PARTICIPANTS: The expert panel in Ireland consisted of representatives from respiratory medicine, cardiothoracic surgery and allied-health professionals with expertise in COPD care.

RESULTS

Of the initial 33 statements in five dimensions, there were consensus regarding 31 statements.

CONCLUSIONS

The 31 statements agreed through this Delphi study clarify a coherent direction for development of a LVR framework in Ireland. The Delphi study methodology described is a useful process to reach consensus among multi-disciplinary experts.
