The Difference in Surgical Waste and Unused Surgical Supplies in Breast Surgery Done at Ambulatory Surgical Center vs Hospital

Puntos clave

The aim is to compare the surgical waste and unused supplies in breast surgery at ambulatory surgical centers versus hospitals.
Conducted at two hospitals and one ASC in Arizona
Included 60 patients at ASC and 20 patients at each hospital
Documented all opened disposable items and reusable equipment
Recorded waste bag weights after surgeries
Significantly lower percentage of unused surgical instruments at ASC vs hospitals (<i>P</i> < 0.01)
Average waste weight lower at ASC (7.97 lbs) compared to hospitals (13.8 lbs and 14.0 lbs)
Costs of unused items were significantly lower at ASC ($52.35) than hospitals ($183.78 and $252.07)

Resumen

BackgroundThis study was performed to determine the amount of waste produced in breast operations in the ambulatory surgery center (ASC) as well as the hospital setting and where potential improvements could be made. MethodsThe study was performed at two hospitals and one ASC in Arizona from January 1, 2025 to September 30, 2025. 60 patients at the ASC and 20 patients were included at each hospital. All the disposable items that were opened were documented. All reusable surgical equipment and instruments were documented. At the conclusion of each case, the weight of the waste bags were recorded. ResultsThe study included 100 patients who had breast conserving operations. The surgeons used 14/70 (20%) and 14/74 (19%) of the instruments at the two hospitals and 14/50 (28%) of the instruments at ASC. A significantly lower percentage of surgical equipment went unused at ASC vs hospitals (P P < 0. 01). The costs of the unused items per case at the two hospitals were 183. 78 and 252. 07, while the cost at the ASC was 52. 35. ConclusionEven in small operations, there is significant waste of valuable resources. More specific trays would lessen waste. Waste was greater in hospitals vs the ASC. This may be another cost saving measure of ambulatory surgery center compared to hospital based surgery.
