Safety of Prophylactic Anticoagulation During Bedside Procedures: A Prospective Multicenter Observational Study

Background: Bedside percutaneous dilatational tracheostomy (PDT) and percutaneous endoscopic gastrostomy (PEG) are common procedures performed in the intensive care unit (ICU). Venous thromboembolism (VTE) prophylaxis is frequently prescribed to ICU patients and it remains unclear whether pre-procedure discontinuation is necessary. Methods: This multi-center prospective observational study aimed to describe bleeding rates in patients undergoing bedside PEG or PDT who did or did not have VTE prophylaxis held. Decision to hold prophylaxis was made by the operating physician. The primary endpoint was the rate of peri-procedural bleeding complications. Secondary endpoints included quantification of held doses in the peri-procedural period, rate of venous thromboembolism, and characteristics associated with having prophylaxis held. Results: 91 patients were included over a 2-year period. Patients were on average aged 54 years, 40% female, mostly admitted to the trauma service (59%), and most commonly underwent bedside PDT (59%). Overall, 21% of patients had doses of pre-procedure prophylaxis held. Bleeding events occurred in 1 patient (1.4%) who had prophylaxis continued and in 1 patient (5.0%) who had prophylaxis held, a rate difference of 3.6% (95% CI–9.5%, 16.7%). One bleeding event was managed with bedside surgical repair and one with blood transfusion. There were 10 VTE events, all of whom had prophylaxis continued during the pre-procedure period but 3 had prophylaxis held after the procedure. Conclusions: Bleeding complications were rare and did not significantly differ depending on whether prophylaxis was held or not. Future research is required to confirm the lack of risk with continuing prophylaxis through bedside procedures.
