Feasibility Study Design

The minimum sample is 16 participants, with 4 per group across advanced cancer, COPD, heart failure, and healthy volunteers. The target sample is 120–180 young women and girls aged 14–18, plus up to 36 staff members. The sample of 55 patients from one Danish region is not generalisable and results should be treated as descriptive feasibility evidence rather than efficiency benchmarks. The feasibility phase included 12 people with dementia, 14 informal caregivers, and 33 nurses. The feasibility study is intended to determine whether a larger confirmatory trial can be conducted, not to prove clinical effectiveness. The pilot recruited twelve participants, including seven older adults and five adolescents. The findings are indicators of feasibility rather than proof of effectiveness. Average session attendance was 83%. Two participants dropped out during the study. ED physician time was not measured beyond direct consultation contact counts, representing a gap to be addressed during tariff construction. All nurses completed the full programme, but only five of twelve dyads completed it fully. The study was a prospective feasibility trial and was not designed for statistical compariso…
