The AblaNor registry demonstrated very good national coverage and completeness of data, with a high degree of reliability (0.61 - 0.80) for most variables.

The Norwegian National Electrophysiology and Ablation Registry (AblaNor) demonstrates high data completeness and interrater reliability, supporting its validity for quality improvement and research.
OBJECTIVES: Data quality is a prerequisite for the use of registries. AblaNor is a nationwide medical quality register of Norwegian patients undergoing electrophysiology examination and ablation. The aim of this study is to assess the coverage of registrations and completeness and reliability variables in AblaNor. DESIGN: National coverage was assessed by comparing electrophysiology (EP) patients registered in the Norwegian Patient Registry (NPR) and AblaNor in2021. Completeness of AblaNor registrations was calculated by examining fraction of missing data in key variables. To study reliability, 13 dummy patients were invented and distributed to electrophysiologists in all five EP-centers in Norway. Interrater reliability between the five ratings was assessed for categorical variables by calculating observed percent agreement (PA), Gwet's agreement coefficient (AC1, AC2) and Krippendorff's alpha coefficient (K alpha) Intra class correlation coefficient (ICC) was calculated for continuous variables. RESULTS: 0.61 - 0.80) reliability. CONCLUSIONS: Data in AblaNor shows very good national coverage and completeness of data, with a high degree of reliability for most variables.
Vavik et al. (Thu,) conducted a observational in Electrophysiology examination and ablation. Norwegian National Electrophysiology and Ablation Registry (AblaNor) vs. Norwegian Patient Registry (NPR) was evaluated on Coverage, completeness, and interrater reliability. The AblaNor registry demonstrated very good national coverage and completeness of data, with a high degree of reliability (0.61 - 0.80) for most variables.
