The benefits of collaboration: the Nordic Arthroplasty Register Association

[摘要] The Nordic countries, including Denmark, Sweden, Finland and Norway, all have a long and successful tradition of arthroplasty registers.

However, the results presented by the Nordic registers have suggested differences among the countries related to variations in data collection systems, variables that are included, variable definitions and statistical methods used. Reports from the Nordic registers have further shown differences regarding the incidence and indication for surgery, characteristics of the joint replacement populations, implants used, fixation methods used and implant survival. Due to these differences, the results from the different Nordic registers have not been fully comparable. Furthermore, although the Nordic registers are populationbased, the number of patients included in specific subpopulations (e.g. patients that have undergone joint replacement due to rheumatoid arthritis (RA) or patients operated due to osteonecrosis) or the number of patients incurring specific adverse events after surgery (e.g. revision due to infection or periprosthetic fracture) are relatively small, which limits the statistical precision of risk estimates and the possibility to draw valid conclusions.
