Reducing instruments in a vitrectomy surgical tray: cost savings and results from a major academic hospital

Abstract

Abstract Background Unused or rarely used instruments in standard surgical trays can unnecessarily increase costs. Prior studies have demonstrated the practicality and cost savings of reduced instrument tray sizes in various subspecialties. This study describes results and estimated cost savings from a reduced instrument tray used for vitrectomy surgery at a large, tertiary academic medical center. Methods Common usage patterns of vitrectomy instruments by one retina surgeon were reviewed and a reduced instrument vitrectomy tray was created and implemented in successive vitrectomy surgeries. Need for opening the previously utilized larger tray was recorded. Estimated cost savings of the new trays were calculated based upon per instrument sterilization, processing, and instrument replacement costs. Results New vitrectomy trays including just 7 instruments (89% reduction compared to original trays) were created and implemented in 189 successive cases. The original tray was never opened. Estimated cost savings from saved sterilization and processing resources is approximately $9588 per year. Assuming 5- and 10-year lifespan per instrument, annual cost avoidance is projected at $7886 and $15,772, respectively. Other indirect benefits relevant to healthcare quality were also noted. Conclusion A reduced instrument tray can be successfully implemented for vitrectomy surgery and can result in significant indirect benefits as well as direct cost savings from reduced sterilization costs. Our study highlights the substantial impact made by evaluating the usage pattern and making appropriate instrument tray changes for just one retina surgeon. Applying these same methods to other surgeons and specialties can have significant implications on healthcare costs and quality.
