Quality registry improves the data of chronic ulcers: Validation of Tampere Wound Registry.

Quality registries are potential tools for improving health care documentation, but the quality and completeness of each registry should be ensured. This study aimed to evaluate the completion rate (completeness) and accuracy of data, first contact-to-registration time (timeliness), and case coverage of the Tampere Wound Registry (TWR) to assess whether it can be reliably used in clinical practice and for research purposes. Data from all 923 patients registered in the TWR between 5 June 2018 and 31 December 2020 were included in the analysis of data completeness, while data accuracy, timeliness and case coverage were analysed in those registered during the year 2020. In all analyses values over 80% were considered good and values over 90% excellent. The study showed that the overall completeness of the TWR was 81% and overall accuracy was 93%. Timeliness achieved 86% within the first 24 h, and case coverage was found to be 91%. When completion of seven selected variables was compared between TWR and patient medical records, the TWR was found to be more complete in five out of seven variables. In conclusion, the TWR proved to be a reliable tool for health care documentation and an even more reliable data source than patient medical records.
