Optimizing patients' functional status during daily nursing care interventions: A systematic review.

The review included studies with varied designs and methodological quality scores from 40% to 86%, and only one study reported adjusting for cluster effects, so some null results may reflect insufficient sample size. The interventions were multicomponent, so the review cannot determine the contribution of any single component. Many significant differences were small or short-lived; for example, a Barthel Index difference of 0.9 points on a 0 to 100 scale was reported, and some effects did not last to 6 months. Adherence varied: four studies reported variability in how staff delivered the intervention, so it is unclear whether nursing staff consistently used the interventions. The review may have missed relevant studies because title screening was done by one person, and it excluded studies with low quality scores. Significant effects were found in long-term or home care, not acute hospital settings, so generalizability to hospital patients is limited.

Do not conclude that daily nursing care interventions reliably improve function. Only 5 of 18 studies showed a significant improvement in functional status, and 12 studies showed no positive effect. The included studies had quality scores from 40% to 86%, and one significant Barthel Index difference was 0.9 points on a 0 to 100 scale. The interventions were multicomponent, so the review cannot show that any single component caused the changes.
