Arthroplasty registries have played a key role in the treatment of patients with various joint diseases and conditions since their conception. Swedish hip and knee arthroplasty registries were initiated in late 1970's. The main aim of registries was to create feedback to surgeons. During the last two decades with introduction of patient reported outcomes, data from registries have been increasingly used to compare caregivers and to improve quality of health care. According to the Swedish Hip Arthroplasty Register (SHAR) Sahlgrenska University Hospital had been underperforming during years 2006–2012. In order to improve the outcomes a systematic data driven approach using local and national registries, based on value based management was undertaken.

Representatives from all categories of healthcare staff and patients were invited to join a newly initiated group. The group was asked to define which measurement that contributed most to improve healthcare. Data from SHAR and local registries were used and seventeen different areas of improvement were identified. Several workgroups were initiated.

Between years 2013 and 2017 there was an increase of 60% in the annual volume of elective THAs. The length of stay decreased from 6.4 days to 1.8 days. Satisfaction with outcome of surgery increased from 76% to 90%. Adverse events decreased from 28% to 10%. The risk of re-operations within 2 years decreased from 2.4% to 1.9%.

Data from a national and a local registry were used to identify and implement changes in a large university hospital. Engaging member of staff and creating a graphical tool for continuous feedback drastically improved the quality of care whilst increasing the availability of hip replacements and reducing costs. This project demonstrates the power of registry data and a patient centered approach in engaging staff and improving healthcare.
