Abstract
Purpose: As part of a fracture treatment registry, a questionnaire was developed to record the general state of health of the patients, the result of fracture treatment and complications. This resulted in the "Fracture Evaluation Since Hospitalization" score, or FRESH- score. The development and validation of the FRESH- score is the subject of this manuscript.
Methods: For validation, the EQ-5D-5L was used as a matching questionnaire. 237 patients were contacted via mail and received both questionnaires. The reliability was determined testing the internal consistency by Cronbach's alpha, convergent validity was tested with the Pearson correlation, construct validity was determined using the Wilcoxon rank sum test, as well as the paired t-test.
Results: Cronbach's alpha for reliability was moderate at 0.57. Convergent validity using Pearson's correlation resulted in a moderate correlation with a coefficient of 0.41. Construct validity was determined using the Wilcoxon rank sum test, as well as the paired t-test. Both methods showed a high significance of p=0.0287 and a tendency p=0.0677, which represents a relationship between the two samples. Content validity was tested using missing values, which were low at 8% on average.
Conclusion: The FRESH- score proved to be reasonable, reliable and sufficiently valid. Application with a larger samples would strengthen the validity of the questionnaire. The score fills a gap between existing questionnaires in orthopedics. An advantage of the FRESH- score is its concise set up and broad applicability.
