“One blade, two cuts?” A multidisciplinary survey investigating practice variability of scalpel blade change for simultaneous excision of multiple skin lesions in the same patient

Abstract

AbstractBackgroundSkin cancer incidence increases globally, requiring effective preventive measures and evidence‐based treatment strategies. Current guidelines advocate for surgical excision as a first‐line treatment for most early skin cancers. The study investigated practices regarding changing scalpel blades when excising multiple skin lesions in the same patient during the same visit (CSB) and explored how beliefs about iatrogenic seeding influence individual norms of practice.MethodsA multidisciplinary survey was conducted among 173 medical specialists involved in skin cancer care. Participants provided demographic information, years of experience, and practices regarding CSB in four clinical scenarios (first excised tumor: basal cell carcinoma, squamous cell carcinoma, melanoma suspect, and evident melanoma). Practice variations based on specialty, experience, and beliefs about seeding risk were statistically assessed.ResultsSurgeons exhibited a significantly higher tendency to change blades compared to non‐surgeons across all diagnoses. Iatrogenic seeding (56.52%) and clinical training (18.84%) were the main reasons provided for CSB. Beliefs about seeding risk did not differ significantly between specialties.ConclusionsAlthough the practice of CSB lacks strong scientific rationale, the approach to this practice significantly varies among different medical specialties. Healthcare professionals should critically evaluate and standardize evidence‐based practices to ensure optimal patient care and mitigate potential harm.
