Nursing intervention to meet the family members' needs during the surgery waiting time.

The study was quasi-experimental with a non-randomised comparison group, so differences between groups may reflect selection or other factors rather than the intervention. Family members were selected by convenience at one Colombian institution, so results may not transfer to other settings or cultures. The intervention included several components, including a video, surgery start and end information, and family-patient reunion, so the contribution of any single component cannot be separated. The outcome was family satisfaction with nursing care, not patient recovery, complications, anxiety, or clinical outcomes. The paper's reporting of the overall quality dimension is inconsistent: it states both groups were rated good and no significant difference, while also reporting a significant increase. Family members of patients under 18, previously in intensive or specialised care, and family members with mental disorders were excluded, so applicability is narrower.

Do not conclude that the video or the waiting-room information alone caused higher satisfaction. The intervention combined several components, and the groups were not randomised, so the study cannot separate their effects.
