Central Venous Catheter Guidewire Retention: Lessons From England's Never Event Database

Objectives Guidewire retention during central venous catheter (CVC) insertion is considered a "never event." We analyzed the National Health Service England Never Event database (2004-2015) to explore the process of guidewire retention and identify potential preventative measures. Methods We performed a systematic analysis of reported retained guidewire incidents by 3 independent reviewers. Results There was a rising frequency of reported retained CVC guidewires, with an average of 2 never events per month. Only 11% of retained guidewires are identified during the procedure itself, with the remainder identified during equipment clear-up (6%), after the procedure (4%), at the first check radiograph (23%), or after the first radiograph (55%). In 59 cases, the grade of the operator was reported, and among these, 88% were inserted by trainee doctors. Analysis of causative factors was only possible for 38 cases, and of these, operator's mistake (32%), operator/human error (16%), and distraction (16%) were the most common. Of 163 reported cases, preventative measures instigated were actions taken against the individual clinician (36%), departmental actions such as investigations, additional teaching or reminders (37%), and additional checklists (27%). Conclusions Most retained guidewires are discovered after the procedure. Despite the introduction of safety measures, guidewire retention still occurs because the checks, alerts, reminders, and additional checklists all solely rely on the operator remembering not to make the mistake. System changes or design modifications to the CVC equipment are needed to prevent guidewire retention, this being at the top of the hierarchy of intervention effectiveness.
