Development of an Italian Questionnaire for Splenectomized Patients Using a Delphi Consensus Method

This study aims to develop an Italian-language questionnaire assessing awareness, knowledge of infectious risk prevention strategies, and vaccination attitudes among splenectomized individuals. The questionnaire will be developed through a structured Delphi consensus process involving a multidisciplinary panel of healthcare professionals experienced in infection prevention and vaccination strategies. Two Delphi rounds will be conducted online to evaluate item relevance and clarity. Items reaching predefined consensus thresholds will be included in the final questionnaire. The resulting tool will support future studies assessing preventive care awareness and vaccination uptake among splenectomized patients.
