Currently there is no national data set or a standardised way that diabetes-related foot ulcers (DFU) outcomes are reported in NZ High-Risk Foot Services. The project is comprised of two studies. Study 1 will analyse current data from the Waitemata District Health Board (WDHB) High-Risk Foot Service to present what DFU outcomes (key indicators) were reported within the service. Study 2 will use a Delphi technique to gain national consensus surrounding what key indicators should be reported. The project will lay the foundation for the development of a common reporting language (data dictionary) to guide the collection, measurement, and reporting of DFU data in NZ High Risk-Foot Services. The project will create future health service delivery research. Staircasing from this research will be the development of an NZ DFU data dictionary and the creation of a national DFU data set across all High-Risk Foot Services in NZ.
