Examination Of Data Validity Of Hip Fracture Patients In A Hungarian Hospital

Introduction: Hip fractures pose a heavy burden on healthcare systems. In Hungary, 13 000?15 000 patients experience hip fractures, most of them undergo surgery. Their survival was examined by the EuroHOPE and BRIDGE studies, using patient level data from the National Health Insurance Fund. Data from healthcare financing reports have been examined worldwide, with contradicting results, so we considered it necessary to observe data validity for hip fractures before further analysis. Objective: The aim of our study was to observe a representative sample of patient records in a Hungarian hospital in order to validate the finance reports. Method: We matched a representative sample of hip fracture patient records in a Hungarian hospital with hip fractures in 2015 with the database of the EuroHOPE and BRIDGE studies. The databases were matched on record level, the analysis included ten data fields and was conducted for data fields and records. Results: The sample included 259 cases. No differences were observed in the patients? gender, age and main diagnosis, or dates of discharge. One difference was observed in the dates of admission, and 5 in the dates of surgery. Minor differences were found in the types of surgery (2?4 cases), but the differences between the databases in comorbidities and complications were large. Conclusion: Based on our results, we can conclude that data fields containing alphanumeric codes, numbers or dates (e.g., main diagnosis, admission, discharge and surgery dates) can be used for further analysis, but comorbidity and complication data are not recommended for research purposes.
