Exploring Individual's Dynamic of Appraisal of Situational Aggression Average Score, Nursing Intervention and the Impact on Aggression.

The study was retrospective and used routine clinical files, so nurses were not randomly assigned interventions and some patients may have received interventions for reasons not captured. Intervention data depended on nurses' own documentation, which may have omitted information and gave no measure of intervention quality. The sample was 60 patients, and some intervention-risk groups were very small, so several odds ratios need cautious interpretation. Rolling averages were not independent because one high day influenced several rolling averages. The added prediction from the 10-day rolling average had overlapping confidence intervals, so its clinical value is uncertain. Calculating a rolling average manually may be time-consuming and error-prone; the authors suggest it may be more feasible with an electronic DASA system.

The only conflict stated is that Michael Daffern is a co-author of the DASA instrument used in the study.

Do not read the higher aggression odds after limit setting or reassurance as proof that these interventions caused aggression. This was a retrospective file review without random assignment, nurses' documentation may have omitted details, and some low-risk groups contained very few patients.
