A financial evaluation of the centralized repackaging of intracameral moxifloxacin for cataract surgery and its impact on cost reduction

Background: Extensive evidence-based literature supports the use of intracameral (IC) moxifloxacin for the prevention of postoperative endophthalmitis after cataract surgery. The Aurora Pharmacy Packaging Center (APPC) has developed a process for centrally preparing IC moxifloxacin. Purpose: The aim of this study was to evaluate the centralized preparation of IC moxifloxacin production for quality assurance and to quantify a potential reduction in costs. Methods: The APPC\u27s compounding procedure of IC moxifloxacin was evaluated using United States Pharmacopeia (USP) Convention 797 standard and compared with practices described in evidence-based literature. Patients who received IC moxifloxacin intraoperatively from one of 3 ophthalmologists during cataract surgery performed between February 15, 2016, and August 15, 2016, were identified using electronic health records. Cost savings were calculated by reviewing costs associated with drug supplies used by the APPC. Results: The APPC process for the centralized preparation of IC moxifloxacin was deemed compliant with USP 797\u27s sterile compounding standards. USP 797 validation criteria included proper sterile technique, equipment, room sterility and pressure, beyond use dating, and storage. Implementation of the centralized production of moxifloxacin reduced the direct product cost per surgery from $140 to $20 (a cost savings of $120 per surgery). There were 459 cataract surgeries analyzed during the study period, resulting in a savings of $55 080 over 6 months. Conclusion: The APPC\u27s centralized compounding procedure was found to be compliant with pharmacy compounding standards and to yield significant cost savings
