Abstract
INTRODUCTION
Quality assurance of the thyroid surgery has been an important part of the work of the endocrine surgeon. For most analyses, data from register files or studies have been used. Administrative data taken from routine data are increasingly used in quality assurance for evaluation. The aim of the study is to determine the reliability of routine data to analyse the treatment outcome and complications of thyroid surgery.
PATIENTS AND METHODS
In a cross-sectional study, we compared records of 121 patients with thyroid surgery for one year with the data of quality assurance of clinical routine. We determined sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of complications.
RESULTS
Screening of administrative data identified 40 specific complications; 84 by patient records. Sensitivities for the detection of complications using administrative data ranged from 31.3 to 60.0%. Specificities ranged from 97.0 to 100%; PPV were 0.77 - 1.0 and NPV were 0.56 - 1.0.
CONCLUSION
Quality assurance of clinical routine data of the thyroid surgery shows deficiencies in sensitivity accompanied by high specificity. It is necessary to increase the validity of administrative routine data to carry out a reliable clinic quality analysis or to prepare volume-outcome relationships in clinical health service research. The parameter of hypocalcaemia shows the most limitations due to quality assurance of clinical routine data.
