Background:
The number of thyroid gland operations in Germany has dropped continuously over the past 10 years. The typical complications of vocal cord paralysis, hypocalcemia, wound infection and postoperative bleeding still occur with variable incidences in the different hospitals.
Objective:
Do the case numbers or hospital category have an influence on the complication rate and have the distribution of operations and the complication rates changed over the last 10 years?
Material And Methods:
This retrospective observational study is based on anonymized routine data of the General Local Health Insurance Company (Allgemeine Ortskrankenkasse, AOK) and analyses data of thyroid gland operations for benign diseases between 2011 and 2021.
Results And Discussion:
A continuous decrease in the frequency of operations for benign thyroid gland diseases over the course of 10 years in Germany could be confirmed. Additionally, a shift of operations towards hospitals with higher numbers of interventions could be demonstrated. The complication rates of permanent vocal cord paralysis and postoperative bleeding requiring revision have significantly declined. This reduction of complications could not be attributed to patient-specific risk factors or to the observed shift in the distribution of cases across hospitals.
