Background: A substantial expense in surgical care is incurred in the operating room (OR). We evaluated the financial impact of a systematic reduction in instrument tray contents on charges for breast surgery procedures.
Methods: A catalog of OR trays historically used for breast procedures (excisional biopsy, segmental and total mastectomy with or without axillary staging) was reviewed by four dedicated breast surgeons and downsized to a single tray accommodating all surgeon preferences. A matched-case comparison was performed pre- and post-downsizing. Cost analysis for salary and benefits (S&B) and unit supply cost (USC) pre- and post-downsizing were carried out. Instrument number, OR tray weights, set-up, and breakdown times were also compared.
Results: Post-downsizing, OR tray counts were reduced from 132 to 67 instruments (49%) and tray weight decreased from 30 to 20 pounds (33%). Scrub technician set-up and breakdown times were shorter by 22% and 25%, respectively. Comparing 449 matched cases (239 pre- and 210 post-downsizing), S&B and USC post-downsizing were decreased collectively for all procedures (p < 0.0001). With an average variance of S&B and USC (pre- to post-intervention) of $354, and an annualized case load of 813 operations, this could translate into S&B and USC savings of $287,802 per year.
Conclusion: Simply downsizing OR breast trays resulted in decreased combined S&B and USC per procedure, leading to a substantial cost savings for the healthcare system. This measure aligns with a value and quality-based approach to patient care and could be easily replicated across institutions and specialties.
