Abstract

Introduction

The implications of global warming are ever increasing in today's society. As the number of total knee arthroplasties (TKA) performed in the USA increases annually, the total waste produced from them will proportionally increase. This study hopes to quantify and compare the amount of waste created by a TKA in a hospital operating room (OR) and ambulatory surgery center (ASC) to evaluate for any differences in the amount and types of waste created.

Methods

Waste audits were performed on 10 TKAs both at hospital OR and ASC OR. Waste was organized into 6 categories: normal solid waste, recyclable plastics, biohazard waste, laundered linens, sharps, and polypropylene blue sterile wrap. Weight and volume for each waste stream were recorded using a digital scale and ruler.

Results

The total mass of waste produced was higher in hospital based TKAs than in the ASC cases (17.3 kg vs. 14.0 kg, p-value = 0.0028). There was significantly more mass of sterile, normal, and sharps waste at the hospital-based cases. Sterile waste was the largest contributor to the mass of waste in both settings. No difference existed in volume of waste between the hospital and ASC cases (305,866 cm³ vs 260,052 cm³, p-value = 0.2494).

Discussion

TKAs in both settings produce a large amount of waste. Performing TKAs at ASCs could be used to lower the amount of waste produced, resulting in long term benefits to both the environment and the healthcare system.

期刊介绍： Journal of Orthopaedics aims to be a leading journal in orthopaedics and contribute towards the improvement of quality of orthopedic health care. The journal publishes original research work and review articles related to different aspects of orthopaedics including Arthroplasty, Arthroscopy, Sports Medicine, Trauma, Spine and Spinal deformities, Pediatric orthopaedics, limb reconstruction procedures, hand surgery, and orthopaedic oncology. It also publishes articles on continuing education, health-related information, case reports and letters to the editor. It is requested to note that the journal has an international readership and all submissions should be aimed at specifying something about the setting in which the work was conducted. Authors must also provide any specific reasons for the research and also provide an elaborate description of the results.
