Background/Aims Hospital-wide replacement of beds and mattresses, often referred to as an ‘implementation’, can be an efficient way of ensuring that these products are up to date. However, large-scale implementations can be daunting for healthcare managers, with a lack of guidance to support them through this process. This service evaluation aimed to provide practical suggestions to NHS managers who are planning a hospital-wide acute hospital bed and mattress implementation from peers who have completed similar projects. Methods Interviews were conducted with a purposive sample of seven NHS staff members, all of whom had held a leading role in managing and executing an implementation project with the provider Medstrom. Exploratory, qualitative, semi-structured interviews were conducted, with data analysed through content-driven narrative analysis, using NVivo software. Results Four themes relating to large-scale bed and mattress implementation were identified: drivers; specification process; financial process; and physical implementation and training. Communication and planning were considered crucial, as was selecting a provider that could offer support throughout the implementation. Participants had been able to successfully implement a large volume of products, but all felt that a resource allowing healthcare managers to draw on the experiences of others who had previously completed a large-scale implementation project would be beneficial. Conclusions Large-scale mattress implementations are achievable with the right input and support. Learning from the experiences and knowledge of peers who have previously been involved in implementations can be very useful for healthcare managers embarking on this kind of project.
