Background: Ineffective surgical fluid waste management in operating rooms (OR) creates a significant environmental burden, reduces OR efficiency, and adds physical challenges for surgical staff. There is a need for waste management systems that improve OR efficiency, safety, and sustainability. The GREEN study (Greening operating Rooms in EuropE comparing Neptune vs. canisters) was conducted to compare the impact of two fluid waste management systems.
Materials and methods: This 2-arm, nonrandomized, prospective service evaluation of fluid waste extraction was conducted using observational time series and surveys. Fluid waste-related data were collected from routine urologic and orthopedic surgeries across three European hospital sites. The primary endpoint of waste disposal impact was the volume of treated waste after surgery (kilograms) using Stryker's Neptune device (n=43) or canisters (n=41). The authors hypothesized that the surgical waste volume related to Neptune is less than the waste volume related to canisters. Secondary endpoints included time efficiency, user satisfaction, and staff ergonomics.
Results: The total weight of device-related treated waste products was reduced by 98.5% when using Neptune (0.2±0.7 kg) compared with traditional canisters (13.2±16.6 kg; P<0.001). Decreased waste weight also translated to enhanced ergonomic safety for surgical staff, as Neptune reduced surgical fluid weight handled by staff by an average of 34 kg per procedure, a 96% reduction compared to canisters. Furthermore, the use of the Neptune system improved OR efficiency by reducing the number of staff required to manage the fluid suction device (P<0.001) and the time spent disposing of fluid waste (P<0.001).
Conclusion: Stryker's Neptune waste management system significantly reduces the volume of treated waste per surgery and improves OR efficiency, staff safety, and user satisfaction over the traditional canister system. This is a more eco-responsible approach to OR fluid waste management and could be considered in any healthcare establishment that generates fluid waste.
