Development and Psychometric Properties of a Scale Measuring Barriers to Perioperative Hypothermia Prevention for Anesthesiologists and Nurses.

ABSTRACT

PURPOSE: To develop a scale that measures barriers to perioperative hypothermia prevention (BPHP) as perceived by anesthesiologists and nurses. DESIGN: A methodological and prospective psychometric study. METHODS: Based on the theoretical domains framework, the item pool was created through a literature review, qualitative interviews, and expert consultation. The scale was pretested with a sample of 154 key stakeholders in perioperative temperature management and then field tested with 416 anesthesiologists and nurses working at three hospitals in Southeast China. Item analysis, and reliability and validity analysis were performed. FINDINGS: The average content validity index was 0.94. According to exploratory factor analysis, seven factors were obtained that could explain 70.283% of the total variance. Confirmatory factor analysis showed excellent or acceptable goodness-of-fit indices. The reliability analysis demonstrated that the scale had high internal consistency and temporal stability, with Cronbach's α, split-half coefficient and test-retest values of 0.926, 0.878 and 0.835, respectively. CONCLUSIONS: The BPHP scale meets the psychometric criteria for reliability and validity and promises to be a useful quality measure for IPH management during the perioperative period. Further investigations on educational or resource needs and the development of an optimal perioperative hypothermia prevention protocol to narrow the gap between research evidence and clinical practice should be performed.
