Nursing Best Practice Recommendations for Intravesical Instillation in Bladder Cancer: Adaptation to the Portuguese Oncological Care

Abstract The study aimed to translate and adapt best practice recommendations for intravesical instillation of antineoplastic therapy by the European Association of Urology Nurses to the Portuguese oncological context. The work followed the ADAPTE methodology, involving three phases (preparation, adaptation, and finalisation), including external review using the Delphi method. The translation and adaptation resulted in terminological standardisation and the exclusion of elements misaligned with the national context. Recommendations that did not reach consensus within the working group (n=16) were externally evaluated by expert nurses in intravesical antineoplastic therapy from various oncological contexts identified by intentional and snowball sampling (N=19 Round I, N=16 Round II). Four initial recommendations did not reach consensus; two were eliminated, and the remaining were evaluated in a second round. This study successfully adapted the recommendations to the Portuguese context, promoting evidence-based practices. Validation by an expert panel confirms their relevance and applicability, strengthening oncological care in Portugal.
