Registration in the Danish Hip Arthroplasty RegistryCompleteness of total hip arthroplasties and positive predictive value of registered diagnosis and postoperative complications

Abstract

We conclude that the Danish Hip Arthroplasty Registry is a potentially valuable tool for quality improvement and research due to the high degree of completeness of registrations regarding THA, and its moderate-to-high positive predictive value of registration for diagnoses in patients undergoing primary THA. However, information on several diagnoses for primary THA and on postoperative complications should be used with caution.
