Comparison of Operator Workloads Associated with the Single-unit Anyfusion^® Pump and the Changeover from a Syringe Pump to an Infusion Pump

Abstract

BackgroundA changeover from a syringe pump to an infusion pump may transiently interrupt drug administration and result in medication errors. A newly developed infusion device (Anyfusion®) that combines the functions of an infusion pump and a syringe pump in a single unit was recently commercialized. This study compared the operator workloads associated with the Anyfusion® pump and with the conventional method using two infusion devices (a syringe pump and an infusion pump).MethodsThis was a prospective, randomized, crossover-designed simulation study using an imitation arm with an intravascular line. We compared the two methods in terms of total execution time, total number of button clicks, and subjective difficulty using a numerical rating scale with a score from 0 (extremely easy) to 10 (extremely difficult).ResultsTwenty-two nurses successfully performed both interventions according to the allocated sequence. Total execution times did not differ between the two methods (129.5 ± 23.2 seconds for the conventional method vs. 121.2 ± 24.3 seconds for the Anyfusion® method; P = 0.244), although the total number of clicks was significantly fewer using the Anyfusion® than the conventional method (median [interquartile range]: 10.0 [9.0–12.0] vs. 21.0 [20.0–25.0], respectively; P < 0.001). Participants rated the Anyfusion® method as easier than the conventional method (1.7 ± 1.2 vs. 3.6 ± 1.6; P < 0.001, respectively).ConclusionThe introduction of Anyfusion® lessened the workload of practitioners required by the changeover process, which might reduce the risk of medication errors and subsequent patient harm.Trial RegistrationClinical Research Information Service Identifier: KCT0004172

Machine Learning Methods to Investigate Drug Delivery in Infusion Pump

“…The performance of the infusion pumps for effective drug and fluid delivery has been analyzed statistically using prediction models [11]. Besides, the impact of flow rate based on the carrier fluid has been investigated [12].…”

Simulation Analysis of Flow Rate Variability During Microinfusions: The Effect of Vertical Displacement and Multidrug Infusion in Conventional Infusion Pumps Versus New Cylinder-Type Infusion Pumps

“…[14][15][16] A cylinder-type infusion pump with a new driving mechanism was recently developed to integrate the advantages and compensate for the disadvantages of existing infusion pumps. 17,18 We compared the flow rate variabilities caused by vertical displacements of the pump body between the new cylinder-type pump and representative, conventional infusion pumps with different driving mechanisms. In addition, we also evaluated flow rate variability during multidrug infusions.…”
