Comparison of Three Reconstitution Devices: A Simulated Time and Use Study

Area of Science:

• Pharmaceutical Sciences
• Clinical Pharmacy Practice
• Drug Delivery Systems

Background:

• Accurate cefazolin reconstitution is crucial for effective intravenous therapy.
• Evaluating reconstitution devices is essential to minimize errors and optimize drug administration.
• Previous studies have not comprehensively compared residual volumes, preparation times, and user feedback for various cefazolin reconstitution devices.

Purpose of the Study:

• To compare residual volume, preparation time, and user perceptions of three different cefazolin reconstitution devices.
• To identify potential use errors and assess particulate matter after reconstitution with each device.
• To determine the most efficient and user-friendly device for cefazolin reconstitution.

Main Methods:

• Three reconstitution devices were used by participants to prepare and reconstitute cefazolin.
• Timed observations recorded device preparation, assembly, mixing, and drug transfer.
• Participant surveys assessed perceptions, and reconstituted bags were analyzed for residual fluid and particulate matter.

Main Results:

• Residual vial volumes varied, with Device 3 showing the highest percentage of significant residual volume (>0.3 mL).
• Mean total reconstitution time was significantly different between devices, with Device 1 being the fastest (70.98 seconds).
• Device 1 received the highest user satisfaction scores, while Devices 2 and 3 exhibited concerning use errors and higher residual volumes.

Conclusions:

• Device 1 demonstrated superior efficiency and user preference in cefazolin reconstitution compared to Devices 2 and 3.
• Significant residual volumes and potential use errors associated with Devices 2 and 3 may lead to incomplete medication dosing.
• Further optimization of reconstitution devices is needed to minimize residual waste and ensure accurate drug delivery.
