Assessing the Palliative and End-of-Life Care Education-Practice-Competence Triad in Intensive Care Units: Content Validity, Feasibility, and Reliability of a New Tool

Background: To date, a comprehensive, psychometrically robust instrument to assess palliative and end-of-life (PEOL) care education, practice, and perceived competence among intensive care unit (ICU) nurses does not exist. Objective: To examine content validity and reliability of a proposed instrument to assess the PEOL care education-practice- competence triad among ICU nurses. Methods: An international modified e-Delphi and a cross-sectional pilot questionnaire survey. The Delphi involved 23 panelists from 11 countries. The pilot study involved 40 staff nurses and 3 nurse managers from 3 adult ICUs in a randomly selected hospital in Egypt. An instrument was developed and judged for content validity by international panelists, and then pretested in a pilot study, where data were collected at 2 time points using self-administered questionnaires, followed by cognitive interviews. Test-retest reliability was examined using intraclass correlation (ICC), standard error of measurement (SEM), and repeatability coefficient (RC). Results: The panelists confirmed content validity of the proposed instrument, and staff nurses confirmed its comprehensibility. At the level of the instrument’s total scores, the lowest ICC was .9 (95% confidence interval: .8-.9); and the highest SEM and RC were 4.8 and 13.3, respectively. Conclusions: The PEOL Care Index is a comprehensive, comprehensible, content valid, and reliable instrument to assess the PEOL care education-practice-competence triad among ICU nurses. Construct and criterion validities need to be confirmed in future studies. Applicability of the PEOL Care Index in different settings and cultures needs to be examined.
