High Validity and Completeness of the Septoplasty Surgical Procedure Code in the Danish National Patient Registry.
Introduction: Ensuring the validity and completeness of clinical data is crucial when utilizing nationwide registers such as the Danish National Patient Registry (DNPR) for epidemiological research. The literature on this topic is, however, strongly lacking for Ear-nose-and-throat (ENT) surgery. The aim of this study was to assess the validity and completeness of the septoplasty surgical procedure code in DNPR.
Methods: This population-based validation and completeness study included all cases of septoplasty surgical procedure codes registered in the DNPR in 2021 and 2022 at the ENT department at Odense University Hospital (OUH) in Denmark. The unique personal registration number was used to identify cases from the DNPR in OUH data registrations. All surgical notes were evaluated manually to determine whether septoplasty had been performed. The primary outcomes were validity (PPV) and completeness assessed as the sensitivity, presented with 95% confidence intervals (CI).
Results: A total of 479 cases were identified from the DNPR. Upon evaluation of the surgical notes and after withdrawal of duplicates, 470 cases were confirmed to have undergone septoplasty, resulting in a PPV of 99% (95% CI (97.6-99.7)). From the OUH data registrations, 485 registrations of septoplasty were identified. Evaluation of the surgical notes left 475 cases of confirmed septoplasty, corresponding to five missing cases in the DNPR, resulting in a sensitivity of 99% (95% CI (97.6-99.7)).
Conclusion: This study showed high validity and completeness for registrations of the septoplasty surgical procedure code in the DNPR. We therefore conclude that the DNPR is a reliable tool for epidemiological research concerning septoplasty.
期刊介绍：
Clinical Epidemiology is an international, peer reviewed, open access journal. Clinical Epidemiology focuses on the application of epidemiological principles and questions relating to patients and clinical care in terms of prevention, diagnosis, prognosis, and treatment.
Clinical Epidemiology welcomes papers covering these topics in form of original research and systematic reviews.
Clinical Epidemiology has a special interest in international electronic medical patient records and other routine health care data, especially as applied to safety of medical interventions, clinical utility of diagnostic procedures, understanding short- and long-term clinical course of diseases, clinical epidemiological and biostatistical methods, and systematic reviews.
When considering submission of a paper utilizing publicly-available data, authors should ensure that such studies add significantly to the body of knowledge and that they use appropriate validated methods for identifying health outcomes.
The journal has launched special series describing existing data sources for clinical epidemiology, international health care systems and validation studies of algorithms based on databases and registries.
