ABSTRACT

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.

ABSTRACT

BACKGROUND: Unintentional extubation is a well-documented and potentially life-threatening phenomenon. There is little research into the factors that lead to unintentional extubation, and therefore how to prevent it. Endotracheal tubes (ETTs) are commonly secured with 1 cm twill tape, but there is little evidence on how to best tie them in place. We have devised a new knot for securing these tubes in place, and we have assessed its degree of slippage when exposed to both perpendicular and sliding forces in comparison with other commonly used knots. METHODS: We constructed a weighted apparatus to test the effects of these forces and measure whether conventional ETTs slipped. We tested the knots both wet and dry to better simulate the clinical environment. We also conducted a manual manipulation test in which a single operator attempted to slide the knot along the ETT. Each knot was tested 10 times for the weight test under both wet and dry conditions, and 8 times for the slip test. RESULTS: The normal knot slipped when weighted both wet and dry, while the clove hitch failed the weight test only when wet. Both the modified cow hitch and double hitch withstood all weights. Only the double hitch did not slip under any circumstances on either test. CONCLUSIONS: The new double hitch was superior to all conventional knots tested. It did not slip under any conditions and therefore may be of use to prevent unintentional extubation, particularly in the ICU setting.
