Background: We investigated the safety and feasibility of ultrasound-guided peripherally inserted central venous catheter (PICC) placements performed by intensive care medical trainees in comparison to PICC placements performed by intensivists. Methods: This was a retrospective and observational study of adult patients who underwent PICC placement and were admitted to the intensive care unit (ICU) between July 2013 and March 2018. Ultrasound-guided PICC was performed at the bedside by an intensivist or intensive care medical trainee if intrahospital transport was inappropriate. The primary endpoint was PICC-induced complications. The secondary endpoint was initial success of PICC. Results: A total of 209 patients underwent PICC placement during the study period. There were no significant differences in age, sex, body mass index, comorbidities, causes of ICU admission, or severity scores between the trainee-led PICC and intensivist-led PICC groups. Difficult venous access (42.6%) and requirement for central line infusion (39.2%) were the most common reasons for PICC placement. The basilic vein (62.2%) was the most common target vein among patients who underwent PICC. There were no significant differences in complications between the two groups (P=0.473). In addition, the initial success rate and procedural time were similar between the two groups (P=0.108 and P=0.076, respectively). There were no insertional injuries and moderate or severe bleeding in patients with PICC. Conclusion: Ultrasound-guided PICC placement by an intensive care medical trainee may be safe and feasible compared to PICC placement by an intensivist.
