A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

People without a functioning spleen face a lifelong higher risk of serious infections, and preventive measures include vaccination, antibiotic prophylaxis, and patient education. This study uses a modified Delphi consensus method with a multidisciplinary panel of Italian-speaking healthcare professionals to create and refine questionnaire items about awareness, knowledge of prevention strategies, and vaccination attitudes for splenectomized individuals. After a literature scoping review produces draft items, two online Delphi rounds will ask experts to rate each item's relevance and clarity on structured Likert scales, retaining items that meet predefined consensus thresholds. The final Italian-language questionnaire will be composed only of items that achieved expert agreement and will support future research and quality-improvement work on preventive care for asplenic patients.
