Cost-effective use of operating room supplies based on the REMEDY database of recovered unused materials

Environmental sustainability in anaesthesia and critical care

The detrimental health effects of climate change continue to increase. Although health systems respond to this disease burden, healthcare itself pollutes the atmosphere, land, and waterways. We surveyed the 'state of the art' environmental sustainability research in anaesthesia and critical care, addressing why it matters, what is known, and ideas for future work. Focus is placed upon the atmospheric chemistry of the anaesthetic gases, recent work clarifying their relative global warming potentials, and progress in waste anaesthetic gas treatment. Life cycle assessment (LCA; i.e. 'cradle to grave' analysis) is introduced as the definitive method used to compare and contrast ecological footprints of products, processes, and systems. The number of LCAs within medicine has gone from rare to an established body of knowledge in the past decade that can inform doctors of the relative ecological merits of different techniques. LCAs with practical outcomes are explored, such as the carbon footprint of reusable vs single-use anaesthetic devices (e.g. drug trays, laryngoscope blades, and handles), and the carbon footprint of treating an ICU patient with septic shock. Avoid, reduce, reuse, recycle, and reprocess are then explored. Moving beyond routine clinical care, the vital influences that the source of energy (renewables vs fossil fuels) and energy efficiency have in healthcare's ecological footprint are highlighted. Discussion of the integral roles of research translation, education, and advocacy in driving the perioperative and critical care environmental sustainability agenda completes this review.

The Green Operating Room: Simple Changes to Reduce Cost and Our Carbon Footprint

Generating over four billion pounds of waste each year, the healthcare system in the United States is the second largest contributor of trash with one-third produced by operating rooms. Our objective is to assess improvement in waste reduction and recycling after implementation of a Green Operating Room Committee (GORC) at our institution. A surgeon and nurse-initiated GORC was formed with members from corporate leadership, nursing, anesthesia, and OR staff. Initiatives for recycling opportunities, reduction of energy and water use as well as solid waste were implemented and the results were recorded. Since formation of GORC in 2008, our OR has diverted 6.5 tons of medical waste. An effort to recycle all single-use devices was implemented with annual solid waste reduction of approximately 12,860 lbs. Disposable OR foam padding was replaced with reusable gel pads at greater than $50,000 per year savings. Over 500 lbs of previously discarded batteries were salvaged from the OR and donated to charity or redistributed in the hospital ($9,000 annual savings). A “Power Down” initiative to turn off all anesthesia and OR lights and equipment not in use resulted in saving $33,000 and 234.3 metric tons of CO2 emissions reduced per year. Converting from soap to alcohol-based waterless scrub demonstrated a potential saving of 2.7 million liters of water annually. Formation of an OR committee dedicated to ecological initiatives can provide a significant opportunity to improve health care's impact on the environment and save money.

A Post-donation Survey to Assess the Appropriateness of Medical Supply Donations to Freetown, Sierra Leone Following the Ebola Crisis

The Recovery of Equipment for Capacity building OVERseas (RECOVER) initiative at Rutgers New Jersey Medical School involves collection and donation of clean and unused medical supplies that would otherwise be discarded to those desperately in need of those supplies abroad. RECOVER has recently responded to the aftermath of the Ebola crisis and the even more recent mudslide natural disaster in Freetown, Sierra Leone, which had resulted in a considerable diminishing of the local medical supplies. The goal of this study was to assess the match between donated supplies and local needs by using a post-donation survey. In December 2016, we conducted a pre-donation survey inquiring which of the supplies available from RECOVER were needed by four hospitals in Freetown. The survey also asked about specific barriers to keeping such supplies in stock. After each hospital received a shipment of supplies, we administered an online Qualtrics (Qualtrics, Provo, UT) follow-up survey intending to assess the appropriateness of the donated supplies. The survey asked about which wards used what supplies, most useful items, ability to sterilize, and whether the donation provided supplies that would otherwise need to be bought. Recipient hospitals reported the use of 90% of donated supplies. The most useful supplies were gowns, scalpels, gloves, and drapes; All recipients reported the ability to sterilize donated goods. Supplies were used in operating rooms, emergency rooms, and medical wards. Donated supplies provided hospitals with supplies that would typically need to be bought or that were unavailable in the region. No adverse events were reported related to the use of donated supplies. At first glance, our donations appear usable and appropriate for the recipients. We hope to provide a framework for an objective measure of need for hospitals in other low-income countries, using the Freetown post-Ebola crisis as a pilot for the assessment of medical supply donations and the longitudinal impact it can have on global health and surgery overseas. More studies are required to further explore the possible implications of our program including those relating to medical waste management and environmental considerations when donating and shipping disposable supplies to a developing country.

Why be sustainable? The Australian and New Zealand College of Anaesthetists Professional Document PS64: Statement on Environmental Sustainability in Anaesthesia and Pain Medicine Practice and its accompanying background paper

Healthcare’s environmental sustainability is increasingly an area of research and advocacy focus. The Australian and New Zealand College of Anaesthetists (ANZCA) has produced a professional document, PS64, Statement on Environmental Sustainability in Anaesthesia and Pain Medicine Practice, and a background paper, PS64 BP. The purpose of the statement is to affirm ANZCA’s commitment to environmental sustainability and support anaesthetists in promoting environmentally sustainable work practices. This article presents the main features of PS64 and its background paper, and the associated supporting evidence. The healthcare sector is highly interconnected with activities that emit pollution to air, water and soils, considerably adding to humanity’s collective ecological footprint. As anaesthetists, we are uniquely high-carbon doctors due to our work anaesthetising with greenhouse gases (particularly desflurane and nitrous oxide) and our exposure and contribution to large amounts of resource and energy use and waste generation in operating theatres. Discussion is made of the improving research base of anaesthetic life-cycle assessments—that is, cradle-to-grave studies of how much energy, water and so on a product or process requires throughout its entire life. Thereafter, reducing, reusing and recycling as well as water use are examined. Ongoing research efforts within environmentally sustainable anaesthesia are highlighted. Environmentally sustainable anaesthesia requires scholarship, health advocacy, leadership, communication and collaboration. The focus is placed on practical initiatives within PS64 and the background paper that can be achieved by all anaesthetists striving towards more sustainable healthcare practices that reduce waste, reap financial benefits and improve health.

Efficiency improvement in the operating room

BACKGROUND

In the changing health care environment, health systems, hospitals, and health care providers must focus on improving efficiency to meet an increasing demand for high-quality, low-cost health care. Much has been written about strategies and efforts to improve efficiency in the perioperative periods, yet the time when the patient is in the operating room-the intraoperative period-has received less attention. Yet, this is the period in which surgeons may have the most influence.

METHODS

Systematically review published efforts to improve intraoperative efficiency; assess the outcomes of these efforts, and propose standardized reporting of future studies.

RESULTS

A total of 39 studies were identified that met inclusion criteria. These divided naturally into small (single operative team), medium (multi-operative team), and large (institutional) interventions. Most studies used time or money as their metric for efficiency, though others were used as well.

CONCLUSIONS

There is substantial opportunity to enhance operating room efficiency during the intraoperative period. Surgeons may have a particular role in procedural efficiency, which has been relatively unstudied. Common themes were standardizing tasks, collecting and using actionable data, and maintaining effective team communication.

Global public health impact of recovered supplies from operating rooms: a critical analysis with national implications

BACKGROUND

In modern operating rooms, clean and unused medical supplies are routinely discarded and can be effectively recovered and redistributed abroad to alleviate the environmental burden of donor hospitals and to generate substantial health benefits at resource-poor recipient institutions.

METHODS

We established a recovery and donation program to collect clean and unused supplies for healthcare institutions in developing nations. We analyzed items donated over a 3-year period (September 2010-November 2013) by quantity and weight, and estimated the projected value of the program under potential nationwide participation. To capture the health benefits attributable to the donated supplies at recipient institutions, we partnered with two tertiary-care centers in Guayaquil, Ecuador and conducted a pilot study on the utility of the donated supplies at the recipient institutions (October 2013). We determined the disability-adjusted life years (DALY) averted for all patients undergoing procedures involving donated items and estimated the annual attributable DALY as well as the cost per DALY averted both by supply and by procedure.

RESULTS

Approximately, 2 million lbs (907,185 kg) per year of medical supplies are recoverable from large non-rural US academic medical centers. Of these supplies, 19 common categories represent a potential for donation worth US $15 million per year, at a cost-utility of US $2.14 per DALY averted.

CONCLUSIONS

Hospital operating rooms continue to represent a large source of recoverable surgical supplies that have demonstrable health benefits in the recipient communities. Cost-effective recovery and need-based donation programs can significantly alleviate the global burden of surgical diseases.

Surgical waste audit of 5 total knee arthroplasties

BACKGROUND

Operating rooms (ORs) are estimated to generate up to one-third of hospital waste. At the London Health Sciences Centre, prosthetics and implants represent 17% of the institution's ecological footprint. To investigate waste production associated with total knee arthroplasties (TKAs), we performed a surgical waste audit to gauge the environmental impact of this procedure and generate strategies to improve waste management.

METHODS

We conducted a waste audit of 5 primary TKAs performed by a single surgeon in February 2010. Waste was categorized into 6 streams: regular solid waste, recyclable plastics, biohazard waste, laundered linens, sharps and blue sterile wrap. Volume and weight of each stream was quantified. We used Canadian Joint Replacement Registry data (2008-2009) to estimate annual weight and volume totals of waste from all TKAs performed in Canada.

RESULTS

The average surgical waste (excluding laundered linens) per TKA was 13.3 kg, of which 8.6 kg (64.5%) was normal solid waste, 2.5 kg (19.2%) was biohazard waste, 1.6 kg (12.1%) was blue sterile wrap, 0.3 kg (2.2%) was recyclables and 0.3 kg (2.2%) was sharps. Plastic wrappers, disposable surgical linens and personal protective equipment contributed considerably to total waste. We estimated that landfill waste from all 47 429 TKAs performed in Canada in 2008-2009 was 407 889 kg by weight and 15 272 m3 by volume.

CONCLUSION

Total knee arthroplasties produce substantial amounts of surgical waste. Environmentally friendly surgical products and waste management strategies may allow ORs to reduce the negative impacts of waste production without compromising patient care.

LEVEL OF EVIDENCE

Level IV, case series.

Reducing Disposable Equipment Waste for Tonsillectomy and Adenotonsillectomy Cases

Large amounts of waste in hospitals are generated in the operating rooms from disposable surgical supplies. Tonsillectomy/adenotonsillectomy (T&A) cases use many disposable supplies that are not recyclable. It is critical to reduce disposable waste, as such waste directly affects the environment and increases health care costs. The authors noticed a difference between the number of disposable items prepared, available, but almost never used, for each tonsillectomy case between a children’s hospital setting and a university ambulatory surgery center setting. The aims were the following: (1) identify what disposable medical supplies were unnecessarily opened for each case, (2) eliminate all disposable medical waste that was not critical to the case in both settings, and (3) determine the cost reduction at both hospital and surgery center facilities by revising the current disposable instruments/supplies pulled for tonsillectomy cases. The authors report projected cost savings and reduction in waste for one children’s hospital and nationally based on their waste reduction.

One center's experience with lowering medical supply costs in the operating room

The purpose of this study was to assess the possibility of lowering costs to organ procurement organizations by purchasing a custom medical supply pack for use in the operating room. Six hospitals in the organ procurement organization's service area were selected for a cost comparison report on selected medical supply items; 37 items were selected for review. A retrospective review of the itemized hospital bills from recent organ recovery cases at each hospital was completed. A medical supply company was contacted for price quotes on selected items for the supply pack. The price quote from the medical supply company totaled $220.30. The average cost of the items selected from the six hospitals was $822.65. The average cost savings per organ recovery case was calculated at $602.35. Based on an estimated 80 organ donors per year, organ procurement organizations could save as much as $48,188 annually.

Assessment of the economic impact of an overage reduction program in the operating room

STUDY OBJECTIVES

To delineate excessive supply preparation in the operating rooms (ORs) of Yale-New Haven Hospital, and to measure the reduction in such overage as a result of nursing and administration cost-containment efforts.

DESIGN

Before and after trial.

SETTING

Inpatient ORs of Yale-New Haven Hospital.

INTERVENTIONS

After the initial documentation of overage, several cost-containment measures were instituted, including nursing education, review of overage data, and updating of surgical request lists.

MEASUREMENTS AND MAIN RESULTS

The hospital cost of case-specific overage generated by all surgical procedures performed during two 2.5-month periods in 1992 and 1994 (before and after the interventions) were compared. One-thousand three hundred eighteen cases in 1992 were compared with 1,367 cases in 1994. A 45% reduction in mean per case overage occurred between the two assessment periods. Extrapolation of the data to the incidence of similar cases throughout the United States projected a comparable savings.

CONCLUSIONS

Efforts to increase the efficiency of OR supply management can be measured, in part, by overage evaluation, which can serve as a resource for focusing efforts at cost-containment.

Focused versus operating room-wide recovery of unused supplies for overseas reconstructive surgery

Proliferation of programs that recover surplus operating room supplies may effectively address the needs of volunteer overseas surgical efforts. However, these programs tend to garner supplies highly heterogeneous in nature. In order to evaluate the nature and quantity of supplies generated by plastic and reconstructive procedures, we extrapolated the inventory of 71 consecutive cases from our 33,000-case database. Additionally, we examined the recovery of 7 specific supplies from all cases performed at Yale-New Haven Hospital over a 3-year period. Though consistency is unlikely when only plastic and reconstructive surgical cases are examined, operating room-wide recovery may be a reliable source of usable materials.
