Background: Acute Achilles tendon rupture (ATR) is a severe injury that leads to functional deficits and sick leave. No treatment consensus has yet been es- tablished. Data from the Danish Achilles Tendon Database (DADB) can help us monitor and optimize the treatment. Purpose / Aim of Study: To investigate the completeness and data validity in DADB. Materials and Methods: The study was performed as a registry study com- paring data in DADB with data collected from the patient records. Data were collected from 3 of 11 hospitals registered in DADB. The study period was the 1st of January to the 31st of December 2016. Completeness was calculated as ‘patients correctly registered in DADB’ divided by ‘patients eligible for registra- tion’. Validity was calculated as ‘patients with correctly registered data’ divided by ‘patients correctly registered in DADB’. A completeness of 80% was consid- ered satisfactory and a parameter was valid if there was agreement between DADB and the patient record in 80% of the cases. Findings / Results: The total completeness was 77% (155/201). For the non- operated patients 81% (150/185) and the operated patients 31% (5/16). The 7 investigated parameters entered at registration of patients in DADB all showed a validity of 83%-100%. Conclusions: This study showed a satisfactory completeness of data concern- ing the non-operated patients registered in DADB and an unsatisfactory com- pleteness of data concerning operated patients. All investigated parameters were valid. These results suggest that data in DADB, for the non- operated pa- tients, rightfully can contribute to research within the field. Due to a limited sample of operated patients conclusions should be cautious. The logistics con- cerning data collection among operated patients need to be optimized. 154.
