Quality of interaction between the nursing personnel and the informal caregivers of people with memory disorders: A systematic review and metasummary of qualitative studies.

This is a metasummary of qualitative studies, so it describes themes about nurse-caregiver interaction, not effects of a tested communication programme. The review did not include care recipients' own views. Only 10 studies and 596 participants were summarised, and the studies varied widely in setting and method. Seven of the 10 primary studies were more than a decade old, so current practice may differ. The protocol was not pre-registered or published, and reviewers had to decide which sentences counted as findings. Only English peer-reviewed studies were included, and grey literature was excluded. Frequency and intensity percentages show how often themes appeared across studies, not how much they change patient care. Organisational themes were fragmented and based on lower frequencies than the strongest themes.

The review was funded by the Academy of Finland, grant number 331555, and by Turku University Hospital, special grant in aid VTR 13238. The funders did not influence conducting or reporting the review, and the authors declared no conflicts of interest.

Do not read the 80% frequency as an effect on care quality. It shows how often that theme appeared across studies. This review summarises experiences, not tested interventions or patient outcomes.
