Shift in determinants of remote care use from sociodemographic characteristics to health need factors during the course of the COVID-19 pandemic. A follow-up study

<title>Abstract</title> <p> <bold>Background:</bold> Specialized disease centers require nurses with interdisciplinary core competencies; however, standardized systems for evaluating these competencies are lacking. Based on the Iceberg Model, we aimed to construct an evaluation index system for interdisciplinary core competencies of nurses in a digestive disease center using the Delphi method. We sought to provide a scientific basis for the training, evaluation, and management of nursing talent in specialty centers. <bold>Methods:</bold> Grounded in the Iceberg Model and the Chinese Registered Nurse Competency Framework, preliminary competency dimensions and an item pool were developed through literature review and semi-structured interviews. Two rounds of Delphi expert consultation were conducted to screen and finalize indicators at all levels. The mean normalization method was used to calculate the weight of each indicator. <bold>Results:</bold> The questionnaire response rates for the two rounds of Delphi expert consultation were 93.75% and 100%, respectively. The expert authority coefficients were 0.850 and 0.847. Kendall's W coefficients were 0.281 and 0.258, respectively (P&lt;0.01). The final evaluation index system for the interdisciplinary core competencies of nurses in digestive specialty centers comprised eight primary, 26 secondary, and 88 tertiary indicators. <bold>Conclusions:</bold> The evaluation index system for interdisciplinary core competencies of nurses in digestive disease specialty centers constructed in this study is scientifically sound and reliable, with strong specialty-specific characteristics and clinical applicability. It provides a scientific and quantitative basis for the access, training, assessment, and evaluation of nursing talent in specialty centers. </p>
