Design and Validation of a Questionnaire to Measure Interprofessional Collaborative Practice for Auditing Integrated Hospital Care: Empirical Research.

Introduction: Interprofessional teamwork is the key issue of delivering integrated hospital care; however, measuring interprofessional collaboration for auditing is fragmented. In this study, a questionnaire to measure InterProfessional collaborative Practice for Integrated Hospital care (IPPIH) has been developed and validated.

Methods: A four-step iterative process was conducted: (1) literature search to find suitable questionnaires; (2) semistructured stakeholder interviews (individual and in focus groups) to discuss the topics and questions (face validity), (3) pretesting the prototype of the questionnaire in two different integrated care pathways for feasibility, usability, and internal consistency, and (4) testing (content and construct validity and responsiveness) of the revised questionnaire in eight integrated care pathways; the validation and responsiveness was tested by means of exploratory factor analysis, calculation of Cronbach alpha, item analysis, and linear mixed model analysis.

Results: Based on six questionnaires and the opinion of direct stakeholders, the questionnaire IPPIH comprised 27 items. Five different domains could be distinguished: own skills, culture, coordination and collaboration, practical support, and appreciation with the Cronbach alpha varied from 0.91 to 0.48. The self-reported intensity of the collaboration within a specific care pathway significantly influenced the outcome ( P = .000).

Discussion: The product is a questionnaire, IPPIH, which can measure the degree of interprofessional collaborative practice in integrated hospital care pathways. The IPPIH was initially developed for quality assurance. However, the IPPIH also seems to be suitable as a self-assessment tool for directors to monitor and improve the interprofessional collaboration and the quality of their integrated care pathway.
