Time-Motion Analysis of Nurses Utilizing Insulin Pen Devices Compared to Vial and Syringe in an Inpatient Setting.

OBJECTIVE: To compare the time taken and steps completed by nurses in the process of insulin preparation and administration using the pen device compared to the vial and syringe method. METHODS: Observational and exploratory study utilizing a time-motion analysis of nurses' administration of insulin using the pen versus vial and syringe delivery methods. Nurses were observed, video-recorded, and timed during insulin preparation and administration using each delivery method. The steps performed by nurses were observed against recommended processes for preparing and administering insulin, and the percentage of nurses completing each step was noted. RESULTS: A total of 137 (94%) nurses participated. Nurses took less time preparing and administering insulin with the pen device compared with the vial and syringe method (79 ± 18 seconds vs 88 ± 20 seconds, respectively, P < .001). The overall average completion rate of steps with the pen device was 90% ± 7% compared to 88% ± 7% with the vial and syringe method. CONCLUSION: The time taken by nurses to prepare and administer insulin was lower with the pen device compared with vial and syringe. Furthermore, areas were identified for potential nursing education to enhance safe and appropriate use of insulin with both delivery methods.

Nurses' perceptions and satisfaction with the use of insulin pen devices compared with insulin vial and syringes in an inpatient setting.

BACKGROUND: The purpose of this study was to compare nurses' perceptions and satisfaction with the use of insulin pen devices versus vial and syringes for insulin delivery in an inpatient setting. MATERIALS AND METHODS: The study used a descriptive design using self-report surveys. Nurses rated their perceptions on a 4-point Likert scale (from 1=strongly disagree to 4=strongly agree) on the ease of use, ease to teach patients, confidence and comfort in use, perceived time efficiency, safety of use, risk of needle sticks, and overall satisfaction and preference with use of each insulin delivery device. RESULTS: In total, 139 (95%) nurses from nine nursing units at one hospital participated in this study. Compared with vial and syringe, nurses felt insulin pens were easier to use to measure insulin dose (mean±SD, 3.7±0.5 vs. 3.1±0.7; P<0.001), were easier to teach patients to use (3.5±0.6 vs. 2.8±0.7; P<0.001), provided more confidence in measuring insulin dose (3.7±0.5 vs. 3.4±0.6, P<0.001), saved on administration and preparation time (3.6±0.5 vs. 2.3±0.8; P<0.001), reduced the risk of giving a wrong dose of insulin (3.2±0.8 vs. 2.2±0.7; P<0.001), and reduced the risk of needle sticks (3.5±0.7 vs. 2.1±0.8; P<0.001). Overall, a majority of nurses preferred the use of insulin pens to vial and syringes in an inpatient setting (83% vs. 15%; P<0.05). CONCLUSIONS: Nurses felt more comfortable and confident with the use of insulin pens compared with vial and syringes and perceived insulin pens to be a safer alternative for both patients and themselves.
