PMID 39467686WHAT IT FOUND
A 22-item bedside checklist lets ICU nurses rate ventilated cardiac surgery patients' compliance by observing behaviour and physical signs.
In 222 patients, lower scores meant better compliance, and ratings stayed stable over 15 minutes.
Key findings
01The CMVS-CSP is a 22-item scale for nurses to assess compliance with mechanical ventilation in cardiac surgery patients, and lower total scores indicate greater compliance.
02In 222 cardiac surgery ICU patients, the final 22 items formed two parts: behavioural reactions and physical reactions.
03When 50 patients were rated twice 15 minutes apart, the total scores did not differ significantly, and the scale's total scores were positively related to an existing patient-ventilator synchrony score.

What it does not show
The scale was tested only in cardiac surgery ICU patients at one centre in Ankara, so it may not work for other ICU patients or hospitals. It was developed for use by nurses, and the study did not test whether other professions could rate patients the same way. Patients who had been reintubated were excluded, so the scale was not tested in that group. The test-retest interval was only 15 minutes, so stability over longer periods was not shown. The study tested the scale's measurement properties, not whether using it improved patient outcomes such as self-extubation, delirium, prolonged ventilation or pneumonia. The authors say further work is needed in other cultures and patient groups.
The easy way to misread this
Do not assume the scale has been shown to improve patient care or that it applies to all ventilated patients. It was tested only in first-time ventilated cardiac surgery patients at one centre, and the study measured the scale's properties rather than patient outcomes.
