Abstract

AbstractIntroduction:Placing peripheral intravenous catheters (“IV lines”) is a standard procedure for health care professionals in acute and emergency medicine. The study aimed to determine the learning curve and success rates in applying IV lines during a three-year paramedic training and the factors influencing successful placement.Methods:This was a prospective and noninterventional observational study to determine the influencing factors, learning outcomes, and performance in the placement of IV lines by trainees and experienced paramedics. Trial registration: German Clinical Trials Register, ID DRKS00024631.Results:From February 1, 2016 through December 31, 2021, a total of 3,547 peripheral venous accesses attempts were performed: 76.5% (n = 2,712) by trainees and 23.5% (n = 835) by experienced practitioners. The trainee group had one-to-three years of training and the experienced group had 11 (SD = 11) years of work experience after training (one-to-35 years). The learning or success curve in the successful placement of peripheral venous accesses was 85.2% in the first year of training, 88.5% in the second year of training, and 92.5% in the third year (and the end of training). It was then 94.3% in the fourth year (first year of being experienced). Successful insertion of peripheral venous accesses in the experienced group was up to 97.0%. The first-attempt success rate was 90.4% across the entire trainee group versus 95.9% in the experienced group (P <.0001).Significant factors influencing successful placement of IV lines were puncture site (P = .022), catheter size (OR = 0.600; P = .002), and number of attempts (OR = 0.370; P <.001). The time of day (or night) was not influential. Work experience, patient age, or blood pressure were also not significant.
