Purpose:
To test the construct validity of an instrument to assess nursing intensity in perioperative settings.
Methods:
A survey based on 24 core elements of perioperative nursing was used. A total of 652 assessments were performed on 308 patients. Principal component analysis was used.
Findings:
A model with four principal components was suggested.
Conclusions:
Patients' care needs appear to vary as they progress along the perioperative continuum. Thus, a given instrument's content differs from the intraoperative to postoperative phases.
Implications:
More testing is needed to achieve a valid tool for allocating nursing staff in operating departments. Reliable tools are needed to match patients' care needs with available nursing resources.
