Area of Science:

Healthcare Management
Surgical Services
Waste Management in Healthcare

Background:

Consigned surgical instruments are frequently used in elective orthopedic procedures.
Unused consigned instruments contribute to significant waste in hospital settings.
Accurate waste calculation is crucial for resource optimization in surgical departments.

Purpose of the Study:

To evaluate waste generated from processing consigned surgical instruments in elective orthopedic surgeries.
To develop a model for calculating waste associated with processing these instruments.
To provide data for improved resource planning and waste reduction.

Main Methods:

A quantitative, descriptive-exploratory case study was conducted in a university hospital.
Phase 1: Retrospective analysis of canceled orthopedic surgeries to identify high-demand sub-specializations.
Phase 2: Prospective observation of instrument processing and development of a waste calculation model.

Main Results:

Hip arthroplasty, spine arthrodesis, and knee arthroplasty showed the highest demand.
854 boxes of consigned surgical instruments were processed but unused.
Estimated processing waste amounted to R$34,340.18 (US$6,359.30).

Conclusions:

The proposed equation effectively calculates waste from unused consigned surgical instruments in orthopedic procedures.
This model empowers nurses with data for better institutional, care, and financial planning.
Identifying waste is key to optimizing resource utilization in surgical instrument management.
