| Summary: | Background: Norway has one of the highest reported incidences of forearm fractures in the world. However, the incidence is based on smaller studies, and these numbers may not be representative for the country as a whole. Normally, recently occurred forearm fractures are registered in the Norwegian Patient Register (NPR), but no validation of the forearm fracture diagnosis code in the register has been performed. Numbers recorded in the register may therefore not be correct and complete. Methods: To investigate the validity of the forearm fracture diagnosis in the NPR, I have compared the reported forearms fractures in the outpatient and inpatient journal systems of the UNN in Tromsø and the hospital of Molde, with confirmed forearm fractures in the x-ray register. I compared the registers by calculating the sensitivity and positive predictive value of registered forearm fractures. Results: The sensitivity was near 100% in both Tromsø and Molde. Nevertheless, we found the positive predictive value to be only 52.6% at the UNN in Tromsø, and 63.8% at the hospital in Molde. Several of the registered forearm fractures in the hospital journal systems were not confirmed in the x-ray register. Conclusion: Although the sensitivity was high in both Tromsø and Molde, showing a high level of completeness, the positive predictive value and therefore the correctness of the forearm fracture diagnosis was low. In general the numbers were somewhat higher in Molde compared to Tromsø. |
