The aim of this study is to evaluate the efficiency of a model of organizational innovation based on advanced practice nurse in the care of people with ostomies (APN-O) versus usual care. An observational, exploratory, analytical, prospective study with a six-month follow-up was carried out at 12 hospitals that implemented this model in Andalusia. A total of 75 patients who had undergone a digestive elimination ostomy and/or a urinary ostomy were followed for six months. Clinical outcomes, healthcare resources, health-related quality of life, and willingness to pay (WTP) were analyzed. The economic evaluation was conducted from a societal perspective, including healthcare costs and indirect costs. The cost difference between the two models was €136.99 and the quality-adjusted life year (QALY) gained was 0.05965 (€2297 per QALY gained). At six months, the mean of WTP was €69 per APN-O consultation. This model contributes to increasing the value-based healthcare in ostomies. Results of this study suggested that APN-O is an effective patient management model for improving their health status and is highly efficient.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/cost-benefit analysishealth care costshealth resourcesnurse specialistsorganizational innovationostomyprospective studiesquality-adjusted life yearsAdultAgedAged, 80 and overCost-Benefit AnalysisFemaleHumansMaleMiddle AgedOstomyPatient CareProspective StudiesQuality of LifeQuality-Adjusted Life Yearsresearch article32823745open access10.3390/ijerph171658791660-4601PMC7460258https://www.mdpi.com/1660-4601/17/16/5879/pdf?version=1597322649https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7460258/pdf
