Medical waste management - how industry can help us to protect environment and money?

Background: The global climate change and its consequences force us to remodel our processes and rethink the current model of providing the HD treatments. Waste management have a massive impact on the environment and the economy. Every HD session produces above 1 kg of medical waste, which should be properly stored and destroyed. In particular in the pandemia time we should improve the dialysis unit budget as well as decrease CO2 emission produced during the waste elimination.Materials and Methods: The checked the weight of different dialyzers used regularly in dialysis centers in Poland. The Kern CM 320-IN scale was used for the measurement. The measurement accuracy was 0.1 g. Also the filling volume of each dialyzer has been taken into consideration.Results: The dialyzers were divided into four groups depending on the surface. 1,4m2 in group one, 1.5-1.6 m2 in group two, 1.7-1.8 m2 in group three and finally 2.0-2.2 m2 in group four. FX class dialyzers were lightest in every group. The heaviest ones were Polyflux dialyzers. The difference between the lightest and heaviest dialyzers was about 95 g. The filling volume was lowest in FX dialyzers and the highest in Elisio dialyzers. The difference was 20 mL.Conclusions: The weight of different dialyzers available on the market differs. The decision-makers should take into account this fact as the additional quality feature. In extreme cases the weight difference reaches 95 g. In yearly perspective, the usage of the lighter dialysis set can cause the 17 million kg decrease of medical waste and significant savings.

An Anesthesia Attempt to Be Green: How Do You Waste Your Carbon Dioxide Absorbers?

Operating room waste is categorized as noncontaminated solid waste (SW) and regulated medical waste (RMW). RMW is treated by autoclaving at an increased economic and environmental cost. We evaluated these costs with a focus on the disposable carbon dioxide (CO2) absorbers. At our institution, exhausted CO2 absorbers were discarded as RMW. We collaborated with product representatives, anesthesia and perioperative staff, and waste management personnel to identify opportunities and barriers for recycling and waste reduction. Ultimately, we agreed to discard CO2 absorbers as SW instead of RMW, a strategy that is practical, less expensive, and more environmentally appropriate.

Financial cost of whole blood and blood component disposals in a Brazilian coordinating blood center.

OBJECTIVE: To describe the reasons for the disposal of blood in the coordinating blood center of the State of Paraná and to estimate the financial costs resulting from potentially avoidable discards. METHOD: A descriptive, retrospective and documentary analysis, with data related to the period from 2010 to 2015 of a Brazilian coordinating blood center collected from a governmental database and analyzed by descriptive statistics. This study was approved by the Ethics Research Committee (CAEE 63074916.0.0000.5225). RESULTS: 101,813 units were discarded, representing 22.3% of the total of 455,684 produced; plasma was the most discharged blood component. The main reason for discarding was lipemia (35.8%); the analysis showed that 56.9% of the disposals were considered potentially avoidable with an estimated paid value of approximately US$2 million. CONCLUSION: The expressive potential of avoidance of disposal of blood units and blood components highlights the importance of planning actions aiming at their best use, contributing to the reduction of amounts paid for these processes.

Blood product wastage reduction by utilising low-cost, low-impact multimodal physician-to-physician communication initiatives.

OBJECTIVES: To assess a multimodal physician-to-physician communication initiative that is low in cost and impact to daily workflow to reduce blood product wastage. BACKGROUND: Blood product stewardship is an important issue in all hospital systems. Previous studies have proposed low-cost interventions to reduce blood product wastage, but few have evaluated improvements in communication between the blood bank and providers. We undertook a prospective quality improvement project focusing on improving communication to reduce blood product wastage. METHODS: We conducted a prospective quality improvement project over the first quarter of 2017, identifying patients with issued but unused blood products. Each service overseeing the care of patients identified on the unit status report was contacted through two possible methods: (i) phone or (ii) proprietary Health Insurance Portability and Accountability Act of 1996 compliant digital messaging application. Collected variables included reserved blood product type and participant time spent. Outcomes included the rate of blood product release and changes in wastage compared with historical data tracked by the blood bank. RESULTS: Eight hundred and forty products were reserved during the study period, of which 436 (52%) were released. Average participant times ranged from 2 ± 1 min to 15 ± 4 min with no significant differences in time spent between participants (P = 0·194). Compared with the average product wastage 10 months prior to project initiation, there were significant reductions in the average wastage for platelets (5·3 ± 2·5 units vs 2·5 ± 1·5 units, P = 0·05), RBCs (6·1 ± 3·7 units vs 0 ± 0 units, P = 0·01) and overall wastage (58·3 ± 14·9 units vs 40 ± 15·7 units, P = 0·05). CONCLUSION: Efforts focusing on improving provider-to-provider communication can reduce blood product wastage.

Implementing an OR Contact Precautions Decision Algorithm to Promote Interprofessional Teamwork for Infection Prevention.

Perioperative nurses use aseptic and sterile technique along with standard cleaning and disinfection practices to prevent surgical site infections. At our hospital, OR team members identified a clinical problem: the lack of a systematic approach to determine the type of postprocedure cleaning required between procedures involving patients with multi-drug resistant organisms or Clostridium difficile. Facility leaders developed a project to design and implement an evidence-based decision-making algorithm to help perioperative nurses rapidly identify the appropriate environmental cleaning procedures for these ORs. After the perioperative nurses were taught how to use the algorithm, it was put into use. Nineteen months later, the nurses completed a postimplementation survey. The results of the survey were generally positive, and the cleaning process was more standardized. We found that a decision-making algorithm was an effective tool to determine the proper postprocedure environmental cleaning between surgical procedures for patients with multi-drug resistant organisms or C difficile.

Unpacking healthcare waste management at rural village health clinics in the Ntcheu District (Malawi).

Management of healthcare waste in low- and middle-income countries lacks a straightforward solution, especially where rural health services are provided. The purpose of our case study was to explore the knowledge and practices of health surveillance assistants operating at rural village health clinics in Ntcheu District, Malawi, with regard to the collection, segregation, transportion, treatment, and disposal of healthcare waste. Data were collected from 81 clinics. The results indicated that while general gaps in both knowledge and practice were observed, sharps (e.g., needles) management was generally being done well. An opportunity for scale-up was found in one clinic, in which local materials had been used to construct a low-cost innovative sharps disposal receptacle that had been modified from a pit latrine design. This study recommends waste management training suitable for rural settings, the promotion of low-cost sharps disposal receptacles using local materials, further opportunities for low-cost incinerators, central waste collection, and encouraging grassroots innovation in healthcare waste management.

Better Pairing Propofol Volume With Procedural Needs: A Propofol Waste Reduction Quality Improvement Project.

BACKGROUND AND OBJECTIVES: Propofol facilitates deep sedation without requiring intubation and is often used by infusion to maintain sedation. Variability in ordering and preparation strategies resulted in significant propofol volumes wasted at the conclusion of procedures in our clinic. With drug shortages now common, we designed a quality improvement initiative to reduce our propofol waste. METHODS: Data collection during the preintervention phase reflected current practice trends. Two propofol dosing tables (≥50 or <50 kg) were designed to estimate the volume of propofol infusion required for sedations spanning 15 to 180 minutes. Nurses prepared propofol infusions as directed by these tables. The primary outcome measure was reduction in waste when the infusion was prepared by standardized strategy versus usual practice. Balancing measures included occurrences of insufficient infusion volume and premature awakenings from deep sedation. Waste volumes were plotted and displayed chronologically in statistical process control charts for the clinic and individual providers. RESULTS: A total of 155 patients received a propofol infusion to maintain deep sedation. The preintervention phase included 77 patients, and the intervention phase included 78 patients. Special cause variation was achieved in the intervention phase. Median (interquartile range) propofol waste volume per procedure declined from 45.6 mL (24.3-71 mL) to 14.3 mL (9.6-19.4 mL), representing a 68% waste reduction. CONCLUSIONS: Using an internally derived systematic approach to ordering and preparing a propofol infusion, we reduced variability, reduced propofol waste, and created cost savings for our organization. This approach is tailorable to other infusions and clinical settings.

Lean and Green Hand Surgery.

Health care in the United States is both expensive and wasteful. The cost of health care in the United States continues to increase every year. Health care spending for 2016 is estimated at $3.35 trillion. Per capita spending ($10,345 per person) is more than twice the average of other developed countries. The United States also leads the world in solid waste production (624,700 metric tons of waste in 2011). The health care industry is second only to the food industry in annual waste production. Each year, health care facilities in the United States produce 4 billion pounds of waste (660 tons per day), with as much as 70%, or around 2.8 billion pounds, produced directly by operating rooms. Waste disposal also accounts for up to 20% of a hospital's annual environmental services budget. Since 1992, waste production by hospitals has increased annually by a rate of at least 15%, due in part to the increased usage of disposables. Reduction in operating room waste would decrease both health care costs and potential environmental hazards. In 2015, the American Association for Hand Surgery along with the American Society for Surgery of the Hand, American Society for Peripheral Nerve Surgery, and the American Society of Reconstructive Microsurgery began the "Lean and Green" surgery project to reduce the amount of waste generated by hand surgery. We recently began our own "Lean and Green" project in our institution. Using "minor field sterility" surgical principles and Wide Awake Local Anesthesia No Tourniquet (WALANT), both surgical costs and surgical waste were decreased while maintaining patient safety and satisfaction. As the current reimbursement model changes from quantity to quality, "Lean and Green" surgery will play a role in the future health care system.

Optimizing Anesthesia-Related Waste Disposal in the Operating Room: A Brief Report.

Misappropriation of noncontaminated waste into regulated medical waste (RMW) containers is a source of added expense to health care facilities. The operating room is a significant contributor to RMW waste production. This study sought to determine whether disposing of anesthesia-related waste in standard waste receptacles before patient entry into the operating room would produce a reduction in RMW. A median of 0.35 kg of waste was collected from 51 cases sampled, with a potential annual reduction of 13,800 kg of RMW to the host institution, and a cost savings of $2200.

Investigating Research Gaps of Pharmaceutical take back Events: An Analysis of take back Program Participants' Socioeconomic, Demographic, and Geographic Characteristics and the Public Health Benefits of take back Programs.

Research continues to show that pharmaceutical environmental contamination causes adverse effects to aquatic life. There are also public health risks associated with pharmaceuticals because in-home reserves of medications provide opportunities for accidental poisoning and intentional medication abuse. Pharmaceutical take back programs have been seen as a potential remedy for these issues; however, a thorough review of past programs indicates limited research has been conducted on take back programs. Furthermore, there are significant gaps in take back program research. To address these gaps and ultimately determine if take back programs could improve public health, research was conducted in conjunction with the take back program Denton drug disposal days held in Denton, Texas. Socioeconomic, demographic, and geographic characteristics of Denton drug disposal days participants were investigated using surveys and Geographic Information Systems. Potential impacts of the Denton drug disposal days program on public health were determined by comparing data from Denton drug disposal days events with data supplied by the North Texas Poison Center. Results suggest that Denton drug disposal days events may have prevented accidental poisonings or intentional abuse, however only qualitative comparisons support this statement and there was insufficient empirical evidence to support the conclusion that Denton drug disposal days events were exclusively responsible for public health improvements. An interesting finding was that there was a definitive travel threshold that influenced participation in Denton drug disposal days events. Overall, this study fills some geographic, socioeconomic, and demographic data gaps of take back programs and proposes methods to analyze and improve participation in future take back programs. These methods could also be applied to improve participation in other local environmentally-focused programs such as household hazardous collection events.

The real-life number of neonatal doses of Bacille Calmette-Guérin vaccine in a 20-dose vial.

BACKGROUND: Reducing vaccine wastage is important. Bacille Calmette-Guérin (BCG) vaccine is produced in vials of 20 infant doses. The reconstituted vaccine is discarded after 4-6 hours. Therefore, to reduce vaccine wastage, a 20-dose vial of BCG is often only opened if at least 10-12 infants are present, jeopardising BCG vaccination coverage and timely vaccination. We observed that nurses were not able to withdraw 20 doses from the vials and aimed to quantify how many doses could be obtained from these vials by experienced nurses under real-life circumstances. METHODS: At the maternity ward of the national hospital in Guinea-Bissau, since 2002 the same two nurses have been vaccinating all eligible children with BCG before discharge. During a month in 2015, within a randomised trial comparing BCG-Denmark and BCG-Russia, we registered how many doses the nurses were able to withdraw from the two types of vaccine vials. RESULTS: The median number of doses which it was possible to withdraw from the vials was 13 (range 11-17): 13 (11-16) for BCG-Denmark (based on 39 vials) and 15 (12-17) for BCG-Russia (based on 29 vials). CONCLUSIONS: In real life, experienced nurses could only obtain 13-15 doses from the 20-dose vials. Thus, vaccine wastage is much lower than assumed. Adjusting practice to the real-life number of doses would immediately suggest vials should be opened if 7 rather than 10 infants are present. As other studies have indicated that BCG may have beneficial non-specific effects on overall mortality, the potential gain by opening a 20-dose vial even for one child may be considerable.

Healthcare waste management: an interpretive structural modeling approach.

Purpose - The World Health Organization identified infectious healthcare waste as a threat to the environment and human health. India's current medical waste management system has limitations, which lead to ineffective and inefficient waste handling practices. Hence, the purpose of this paper is to: first, identify the important barriers that hinder India's healthcare waste management (HCWM) systems; second, classify operational, tactical and strategical issues to discuss the managerial implications at different management levels; and third, define all barriers into four quadrants depending upon their driving and dependence power. Design/methodology/approach - India's HCWM system barriers were identified through the literature, field surveys and brainstorming sessions. Interrelationships among all the barriers were analyzed using interpretive structural modeling (ISM). Fuzzy-Matrice d'Impacts Croisés Multiplication Appliquée á un Classement (MICMAC) analysis was used to classify HCWM barriers into four groups. Findings - In total, 25 HCWM system barriers were identified and placed in 12 different ISM model hierarchy levels. Fuzzy-MICMAC analysis placed eight barriers in the second quadrant, five in third and 12 in fourth quadrant to define their relative ISM model importance. Research limitations/implications - The study's main limitation is that all the barriers were identified through a field survey and barnstorming sessions conducted only in Uttarakhand, Northern State, India. The problems in implementing HCWM practices may differ with the region, hence, the current study needs to be replicated in different Indian states to define the waste disposal strategies for hospitals. Practical implications - The model will help hospital managers and Pollution Control Boards, to plan their resources accordingly and make policies, targeting key performance areas. Originality/value - The study is the first attempt to identify India's HCWM system barriers and prioritize them.

Technology selection for infectious medical waste treatment using the analytic hierarchy process.

UNLABELLED: The overall objective of this paper was to evaluate five different technologies used for infectious medical waste treatment and select the optimum one by means of multicriteria analysis. Steam disinfection was selected as the optimum treatment technology, among others using incineration, microwave disinfection, chemical disinfection with sodium hypochlorite, and reverse polymerization with microwaves. The evaluation was based on four groups of criteria, specifically, environmental, economic, technical, and social criteria, using the analytic hierarchy process. Selection among four commercial systems using steam disinfection was not possible, because it required additional site-specific criteria, e.g., loading capacity and requirements of local regulations. IMPLICATIONS: The paper can help health care facilities to select the system for infectious waste treatment that best fits their needs. It was concluded that steam disinfection was the optimum technology, using environmental, economic, technical, and social criteria.

What's in a bin: A case study of dental clinical waste composition and potential greenhouse gas emission savings.

BACKGROUND: Dental practices have a unique position as dental staff use a high number of dental materials and instruments on a daily basis. It is unclear how dentists' and dental care professionals' choices and behaviours around selecting and using materials impact on the amount of unnecessary waste production. Although there are a number of articles exploring the quality and quantity of waste in dental practices, there are no studies on organisational strategies to decrease unnecessary waste. There is no clear economic analysis of the impact on associated cost to dental practices which consequently can affect the access of dental care for disadvantaged groups. METHODS: This study used an audit approach to explore the potential for sustainability in dental practice by measuring the nature and quantity of dental clinical waste, and assessing the feasibility of measuring the financial costs and potential carbon savings in the management of dental clinical waste. CONCLUSIONS: The data from our study would appear to support the view that it is possible to reduce carbon emissions and increase profitability. Successful implementation of an environmentally sustainable approach to waste management will be dependent on the practicalities involved and the financial incentives for adopting such practices.

Thermal treatment of medical waste in a rotary kiln.

This paper presents the results of a study of an experimental system with thermal treatment (incineration) of medical waste conducted at a large complex of hospital facilities. The studies were conducted for a period of one month. The processing system was analysed in terms of the energy, environmental and economic aspects. A rotary combustion chamber was designed and built with the strictly assumed length to inner diameter ratio of 4:1. In terms of energy, the temperature distribution was tested in the rotary kiln, secondary combustion (afterburner) chamber and heat recovery system. Calorific value of medical waste was 25.0 MJ/kg and the thermal efficiency of the entire system equalled 66.8%. Next, measurements of the pollutant emissions into the atmosphere were performed. Due to the nature of the disposed waste, particular attention was paid to the one-minute average values of carbon oxide and volatile organic compounds as well as hydrochloride, hydrogen fluoride, sulphur dioxide and total dust. Maximum content of non-oxidized organic compounds in slag and bottom ash were also verified during the analyses. The best rotary speed for the combustion chamber was selected to obtain proper afterburning of the bottom slag. Total organic carbon content was 2.9%. The test results were used to determine the basic economic indicators of the test system for evaluating the profitability of its construction. Simple payback time (SPB) for capital expenditures on the implementation of the project was 4 years.

Assessing future scenarios for health care waste management using a multi-criteria decision analysis tool: A case study in the Turkish West Black Sea Region.

The aim of this paper is to identify the best possible health care waste management option in the West Black Sea Region by taking into account economic, social, environmental, and technical aspects in the concept of multi-criteria decision analysis. In the scope of this research, three different health care waste management scenarios that consist of different technology alternatives were developed and compared using a decision-making computer software, called Right Choice, by identifying various criteria, measuring them, and ranking their relative importance from the point of key stakeholders. The results of the study show that the decentralized autoclave technology option coupled with the disposal through land-filling with energy recovery has potential to be an optimum option for health care waste management system, and an efficient health care waste segregation scheme should be given more attention by the authorities in the region. Furthermore, the discussion of the results points out multidisciplinary approach and the equilibrium between social, environmental, economic, and technical criteria. The methodology used in this research was developed in order to enable the decision makers to gain an increased perception of a decision problem. In general, the results and remarks of this study can be used as a basis of future planning and anticipation of needs for investment in the area of health care waste management in the region and also in developing countries that are dealing with the similar waste management problems.
