Abstract

This thesis examines which innovation characteristics most influence the diffusion and adoption of advanced medical equipment in Danish public hospitals. Guided by Everett Rogers’ diffusion of innovations framework, two cases—the Leksell Gamma Knife and the da Vinci surgical system—were assessed through a literature review and complemented by semi-structured interviews with four decision-makers. The analysis applied five attributes: relative advantage, compatibility, complexity, trialability, and observability. Findings indicate that the Gamma Knife has diffused and been adopted more slowly than the da Vinci system, partly due to greater complexity and high costs that do not fully justify its relative advantage, while the da Vinci also holds strong clinician appeal. The thesis concludes that relative advantage—especially improved patient care and clinician appeal—is the most decisive attribute for adopting highly advanced surgical equipment in this context. Complexity and observability also matter in a politically influenced hospital setting, whereas compatibility and trialability appear less decisive, though they are considered in decisions.

Dette speciale undersøger, hvilke innovationskarakteristika der har størst betydning for diffusion og adoption af avanceret medicinsk udstyr i danske offentlige hospitaler. Med udgangspunkt i Everett Rogers’ teori om diffusion af innovationer blev to konkrete cases – Leksell Gamma Knife og da Vinci kirurgisystemet – analyseret via en litteraturgennemgang og suppleret med semistrukturerede interviews med fire beslutningstagere. De fem egenskaber relativ fordel, kompatibilitet, kompleksitet, afprøvbarhed og synlighed blev brugt som vurderingsramme. Analysen peger på, at Gamma Knife har haft en markant langsommere diffusion og adoption end da Vinci, hvilket blandt andet kan tilskrives højere kompleksitet og omkostninger, der ikke fuldt ud retfærdiggør den relative fordel, mens da Vinci også har en stærk appel til læger. Konklusionen er, at relativ fordel—især forbedret patientbehandling og faglig tiltrækning for klinikere—er den mest afgørende egenskab for adoption af højt avanceret kirurgisk udstyr i denne kontekst. Samtidig kan kompleksitet og synlighed spille væsentlige roller i et politisk påvirket hospitalsvæsen, mens kompatibilitet og afprøvbarhed synes mindre udslagsgivende, om end de indgår i beslutningsgrundlaget.
