    Abstract

    Background Musculoskeletal disease is one of the leading clinical and economic burdens of the UK health system, and the resultant demand for orthopaedic care is only set to increase. One commonly used and one of the most expensive hardware in orthopaedic surgery is the surgical drill and saw. Given financial constraints, the National Health Service (NHS) needs an economic way to address this recurring cost. We share evidence of one frugal innovation with potential for contributing to the NHS’ efficiency saving target of £22 billion by 2020.

    Methods Exploratory case study methodology was used to develop insights and understanding of the innovations potential for application in the NHS. Following a global search for potential frugal innovations in surgery, the Arbutus Drill Cover System was identified as an innovation with potential to deliver significant cost savings for the NHS in the UK.

    Results The Arbutus Drill Cover System is up to 94% cheaper than a standard surgical drill available in the UK. Clinical and laboratory tests show that performance, safety and usability are as good as current offerings in high-income countries and significantly better than hand drills typically used in low-and-middle-income countries. The innovation meets all regulatory requirements to be a medical device in the Europe and North America.

    Conclusions The innovation holds promise in reducing upfront and life span costs for core equipment used in orthopaedic surgery without loss of effectiveness or safety benchmarks. However, the innovation needs to navigate complicated and decentralised procurement processes and clinicians and healthcare leaders need to overcome cognitive bias.
