Evaluating Alleged Malpractice Cases Against Cardiologists and Cardiothoracic Surgeons in The Netherlands

This study aimed to analyse alleged malpractice cases and outcomes against cardiologists and cardiothoracic surgeons in the Netherlands. The Dutch Medical Disciplinary Database was searched for verdicts of alleged malpractice cases published between January 2010 and October 2025. Data were collected on case details and outcomes, and descriptive statistics were employed. A total of 219 cases were included (182 cases for cardiology and 37 cases for cardiothoracic surgery). Most cases were due to incorrect treatment/diagnosis for cardiologists and cardiothoracic surgeons (57% and 68%, respectively). Against cardiologists, 45/182 cases (25%) were judged as (partially) founded, for which 25 warnings, 17 reprimands, 1 temporary suspension, and 1 full practice prohibition were imposed. Against cardiothoracic surgeons, 11/37 cases (30%) were judged as (partially) founded, for which 10 warnings were imposed. We report trends and outcomes of alleged malpractice claims against cardiologists and cardiothoracic surgeons in the Netherlands. The cases discussed in this article offer valuable insights that can help enhance patient care.
