There is increased awareness of palliative care needs in people with COPD or interstitial lung disease (ILD). This European Respiratory Society (ERS) task force aimed to provide recommendations for initiation and integration of palliative care into the respiratory care of adult people with COPD or ILD. The ERS task force consisted of 20 members, including representatives of people with COPD or ILD and informal caregivers. Eight questions were formulated, four in the Population, Intervention, Comparison, Outcome format. These were addressed with full systematic reviews and application of Grading of Recommendations Assessment, Development and Evaluation for assessing the evidence. Four additional questions were addressed narratively. An “evidence-to-decision” framework was used to formulate recommendations. The following definition of palliative care for people with COPD or ILD was agreed. A holistic and multidisciplinary person-centred approach aiming to control symptoms and improve quality of life of people with serious health-related suffering because of COPD or ILD, and to support their informal caregivers. Recommendations were made regarding people with COPD or ILD and their informal caregivers: to consider palliative care when physical, psychological, social or existential needs are identified through holistic needs assessment; to offer palliative care interventions, including support for informal caregivers, in accordance with such needs; to offer advance care planning in accordance with preferences; and to integrate palliative care into routine COPD and ILD care. Recommendations should be reconsidered as new evidence becomes available., There is increased awareness of palliative care needs in people with COPD or interstitial lung disease (ILD).

Background:: Missing data can introduce bias and reduce the power, precision and generalisability of study findings. Guidelines on how to address missing data are limited in scope and detail, and poorly implemented. Aim:: To develop guidelines on how best to (i) reduce, (ii) handle and (iii) report missing data in palliative care clinical trials. Design:: Modified nominal group technique. Setting/participants:: Patient and public research partners, palliative care clinicians, trialists, methodologists and statisticians attended a 1-day workshop, following which a multi-stakeholder development group drafted the guidelines. Results:: Seven main recommendations for reducing missing data, nine for handling missing data and twelve for reporting missing data were developed. The top five recommendations were: (i) train all research staff on missing data, (ii) prepare for missing data at the trial design stage, (iii) address missing data in the statistical analysis plan, (iv) collect the reasons for missing data and (v) report descriptive statistics comparing the baseline characteristics of those with missing and observed data. Reducing missing data, preparing for missing data and understanding the reasons for missing data were greater priorities for stakeholders than how to deal with missing data once they had occurred. Conclusion:: Comprehensive guidelines on how to address missing data were developed by stakeholders involved in palliative care trials. Implementation of the guidelines will require endorsement of research funders and research journals.
