FLS Benefits Calculator In just 3 clicks this Calculator will estimate the benefits of implementing an effective Fracture Liaison Service. The benefits are measured in terms of reduced fragility fracture incidence and cost savings that can be realised in a local health economy. This tool has been designed for use by NHS hospitals, community services and commissioning organisations to help develop a local Fracture Liaison Service (FLS). The Calculator will enable you to estimate the financial benefits that can be realised in your local health economy as a result of implementing an effective FLS. The Calculator asks you to input the number of fragility fractures that you would expect to treat in your new or expanded FLS. If you don't have this information you can use the option of calculating these by selecting your local population and referral criteria and then applying national incidence data.
