Development and Validation Process of the Intensive Care Unit Omitted Nursing Care (ICU-ONC) Instrument Among French Canadian Nurses.

Background and Purpose: The purpose of this article is to document the development and validation process of an instrument adapted for French-speaking nurses and to measure the occurrence of omitted nursing care (ONC) in the intensive care unit (ICU). Methods: An electronic Delphi panel, involving ICU nursing experts from the province of Quebec (Canada), was used to develop the intensive care unit omitted nursing care (ICU-ONC) instrument. For the validation process, an electronic cross-sectional survey was conducted. Results: A total of 564 nurses participated in the validation study. Exploratory factor analysis performed on 478 complete observations supports the presence of a single-factor structure for the 22-item ICU-ONC instrument. Coefficient alpha for the scale was.93, 95% confidence interval (CI) was [0.92, 0.94], item–partial total correlations ranged from.49 and.68, and the mean/median interitem correlations were.38 and.37, respectively. Moderate negative correlations were found between the ICU-ONC instrument overall score and two related constructs: nurses' perception of the quality as well as the safety of care. Conclusions: Our current understanding of ONC in the ICU is based on the results drawn from the administration of generic instruments to ICU nurses. The novel 22-item ICU-ONC instrument can help better estimate the occurrence of the phenomena in the ICU.
