Abstract

Objective To describe and compare safety and usability between a peristaltic large-volume intravenous smart pump (IVSP) and a novel pneumatic large-volume IVSP during clinical use.

Methods A prospective, comparative study was conducted in a large, tertiary hospital in the southeastern USA. Safety and usability were measured by observation during medication administration (medication administration error, interruptions, programming time), dose error reduction system (DERS) compliance, end-user surveys and compliance with manufacturer setup requirements. Study implementation began on a small pilot unit for 1 month, followed by data collection on the study unit over 2 months.

Results For the observed medication administrations (N=158): 79 peristaltic (36 primary; 43 secondary) and 79 pneumatic (42 primary; 37 secondary), use of the peristaltic IVSP was associated with significantly (p<0.05) higher medication administration errors and programming time (11.9 s) and a significantly higher number of interruptions during programming.

DERS compliance was significantly less (p<0.001) with the peristaltic (75.9%) as compared with the pneumatic IVSP (99.8%). Programming workload (National Aeronautics and Space Administration Task Load Index) was significantly (p=0.004) higher with peristaltic versus pneumatic IVSP, and the usability (System Usability Scale) was significantly (p=0.007) lower with peristaltic versus pneumatic IVSP. There was a 0% compliance with peristaltic secondary setup requirements in 43 observed infusions.

Conclusions Though nurses had a high level of experience with the peristaltic IVSP, results of this study support that the pneumatic IVSP was easier to use and associated with fewer errors and deviations from safe practices as compared with the peristaltic IVSP.
