In an ageing population, it is inevitable to improve the management of care for community-dwelling elderly with incontinence. A previous study in this population with four or more chronic diseases showed that implementation of the Optimum Continence Service Specification (OCSS) reduced urinary incontinence, improved quality of life, and decreased healthcare and societal costs. The aim of this study was to explore future consequences of the OCSS new care strategy of various healthcare policy scenarios in an ageing population. We adapted a previously developed decision-analytical model in which OCSS was operationalised as the appointment of a continence nurse specialist located within the general practice in The Netherlands. The model included both a healthcare and a societal perspective. All outcomes were computed over a three-year time period using two different base years (2014 and 2030). Settings for future policy scenarios were based on desk-research and expert opinion. Our results show that implementation of OSCC yields large health gains in community-dwelling elderly (2030: 2,592 – 2,618 QALYs gained) and large cost-savings in The Netherlands (2030: healthcare perspective: €32.4 Million – €72.5 Million; societal perspective: €182.0 Million – €250.6 Million). Savings occur in different categories depending on healthcare policy. Implementation of OSCC can result in 1,273 Million less hours of informal caregiving per year. The uncertainty analyses and extreme case scenarios showed the robustness of the results. Implementation of OCSS results in an improvement of the quality of life in community-dwelling elderly, a cost reduction for payers and affected elderly, and less time invested by carer’s. If policy is moving from formal care to informal care, new incontinence care can reduce burden for informal caregivers. Various realistic policy scenarios even forecast larger health gains and cost-savings in the future. More importantly, the longer the implementation is postponed the larger the savings foregone.
