Non-invasive ventilation in the palliative care of patients with chronic obstructive pulmonary disease: a scoping...

Patients with advanced chronic obstructive pulmonary disease (COPD) experience a great symptom burden. Breathlessness is a very frequently reported symptom that negatively affects all aspects of daily life and could lead to fear of dying. Non-invasive ventilation (NIV) could be an important palliative measure to manage breathlessness in patients with advanced COPD. We decided to conduct a scoping review to attain an overview of the existing research and to identify knowledge gaps. This scoping review aims to systematically map published studies on the use of NIV in the palliative care of COPD patients, including the perspectives and experiences of patients, families and healthcare professionals.

This scoping review will employ the framework of Arksey and O'Malley. The reporting will be guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. A comprehensive and systematic search strategy will be developed in cooperation with an experienced librarian. Database searches will be conducted in AMED, PEDro, Embase, CINAHL, PsycInfo and MEDLINE in February 2021. Pairs of authors will independently assess studies' eligibility and extract data using a standardised data-charting form. The data will be inductively summarised and organised thematically. The results will be discussed with an advisory board consisting of nurses and physicians from respiratory and intensive care units.

Approval for the workshop with the advisory board has been attained from the Norwegian Centre for Research Data (480222), and approval will be attained from the Personal Data Protection Officers of the participating hospitals. All advisory board participants will sign an informed written consent before participation. The results could contribute to developing the body of evidence on the use of NIV in the palliative care of COPD patients and serve to identify directions for future research.
