Prevalence and Cost of Routine Preoperative Care for Low-Risk Cataract Surgery a Decade after Choosing Wisely

PURPOSE

Examine the frequency and cost of procedural clearance tests and examinations in preparation for low-risk cataract surgery among members of a commercial healthcare organization in the United States. Determine what characteristics most strongly predict receipt of preoperative care and the probability that preoperative care impacts postsurgical adverse events.

DESIGN

Retrospective healthcare claims analysis and medical records review from a large, blended-health organization headquartered in Western Pennsylvania.

PARTICIPANTS

Members aged ≥ 65 years who were continuously enrolled 6 months before and after undergoing cataract surgery from 2018 to 2021 and had approved surgery claims.

METHODS

Preoperative exams or tests occurring in the 30 days before surgery were identified via procedural and diagnosis codes on claims of eligible members (e.g., Current Procedural Terminology codes for blood panels and preprocedural International Classification of Diseases, 10th Revision, Clinical Modification codes). Prevalence and cost were directly estimated from claims; variables predictive of preoperative care receipt and adverse events were tested using mixed effects modeling.

MAIN OUTCOME MEASURES

Total costs, prevalence, and strength of association as indicated by odds ratios.

RESULTS

Up to 42% of members undergoing cataract surgery had a physician office visit for surgical clearance, and up to 23% of members had testing performed in isolation or along with clearance visits. The combined costs for the preoperative visits and tests were $4.3 million (approximately $107-$114 per impacted member). There was little difference in member characteristics between those receiving and not receiving preoperative testing or exams. Mixed effects models showed that the most impactful determinants of preoperative care were the surgical facility and member's care teams; for preoperative testing, facilities were a stronger predictor than care teams. Adverse events were rare and unassociated with receipt of preoperative testing, exams, or a combination of the two.

CONCLUSIONS

Rates of routine preoperative testing before cataract surgery appear similar to those prior to the implementation of the Choosing Wisely campaign, which was meant to reduce this use. Additionally, preoperative evaluations, many likely unnecessary, were common. Further attention to and reconsideration of current policies and practice for preoperative care may be warranted, especially at the facility level.

Healthcare waste management practice and associated factors among healthcare workers in public healthcare facilities of Southwest Shewa Zone, Oromia regional state, Ethiopia

Poor management of waste can cause serious disease to healthcare personnel, cleaners, waste handlers, patients and the public. An observation-supported cross-sectional study was conducted to assess healthcare waste (HCW) management practice and professional, management and resource availability-associated factors among healthcare workers of 23 public health facilities in Southwest Shewa Zone, Oromia regional state, Ethiopia, 2021. A total of 424 health workers participated in this study. The level of proper healthcare waste management (HCWM) practice was 38.4%. Lack of knowledge on different methods of healthcare waste treatment (adjusted odds ratio (AOR): 0.101, 95% confidence interval (CI) (0.042, 0.242, p < 0.05)), lack of knowledge about the types of healthcare waste (AOR: 0.136, 95% CI (0.039, 0.481, p < 0.05)), lack of knowledge on the use of different colour-coded waste bin and safety box (AOR: 0.145, 95% CI (0.040, 0.520, p < 0.05)), and healthcare workers who had no training/orientation on HCWM practice (AOR: 0.396, 95% CI (0.245, 0.639, p < 0.05)) were less likely to practice effective HCWM compared to their counterparts. The current HCWM practices in studied health facilities was inadequate. Professional knowledge and availability of training were independently associated with HCWM practice. Therefore, regular orientation during employment and on-job training on HCWM practice, regular monitoring and supervision of HCWM are important. Further research should be conducted on the area of HCWM, and its associated environmental impacts by using more strong methods and wider health facilities.

Optimal selection of healthcare waste treatment devices using fuzzy-rough approach

The escalating volume of healthcare waste (HCW) generated by healthcare facilities poses a pressing challenge for all nations. Adequate management and disposal of this waste are imperative to mitigate its adverse impact on human lives, wildlife, and the environment. Addressing this issue in Bosnia and Herzegovina involves the establishment of a regional center dedicated to HCW management. In practice, there are various treatments available for HCW management. Therefore, it is necessary to determine the priority for procuring different treatments during the formation of this center. To assess these treatment devices, expert decision-making employed the fuzzy-rough approach. By leveraging extended sustainability criteria, experts initially evaluated the significance of these criteria and subsequently assessed the devices for HCW treatment. Employing the fuzzy-rough LMAW (Logarithm Methodology of Additive Weights), the study determined the importance of criteria, highlighting "Air emissions" and "Annual usage costs" as the most critical factors. Utilizing the fuzzy-rough CoCoSo (the Combined Compromise Solution) method, six devices employing incineration or sterilization for HCW treatment were ranked. The findings indicated that the "Rotary kiln" and "Steam disinfection" emerged as the most favorable devices for HCW treatment based on this research. This conclusion was validated through comparative and sensitivity analyses. This research contributes by proposing a solution to address Bosnia and Herzegovina's HCW challenge through the establishment of a regional center dedicated to HCW management.

Effect of a waste management intervention program on knowledge, attitude, and practice (KAP) of nurses and housekeepers: a quasi-experimental study, Egypt

BACKGROUND

Improper healthcare waste management practice is alarming in developing countries because resources are inadequate and waste management is often delegated to poorly educated and untrained laborers. This study aimed to compare the pre-KAP versus post-KAP towards the waste management program for nurses and housekeepers. In addition, it aimed to explore possible factors affecting the pre- and post-KAP in Mansoura Emergency University Hospital, Egypt.

SUBJECTS AND METHODS

One hundred thirty-three newly employed nurses, housekeepers, and those who need refreshment training as nominated by head nurses and link occupational health and safety nurses in the hospital were recruited for the study. The study's intervention included multiple training sessions using a PowerPoint presentation in Arabic with appropriate illustrations followed by an open discussion. An Arabic self-administered questionnaire containing demographic and occupational history, knowledge (27 questions), attitude (10 questions), and practice (9 questions) was used pre- and post-intervention.

RESULTS

The overall KAP scores among the studied healthcare workers were significantly higher after the intervention. The pre- and post-knowledge scores were significantly different with respect to education, job description, and duration of employment (p < 0.05). The post-attitude scores were significantly different with respect to education and job description only (p < 0.05). The total pre-practice scores were significantly different with respect to education and job description (p < 0.05). However, the post-practice scores were significantly different with respect to sex, age, education, and job description (p < 0.05).

CONCLUSION

There was a significant improvement in the KAP scores post-intervention. The post-knowledge and attitude scores were significantly better in nurses and participants with a higher education. The post-practice score was significantly better for females, participants with an age ≥ 30 years, higher education, and nursing jobs. The combination of training and supervision was crucial for the success of waste management programs. Higher education levels are required for housekeepers to be capable of gaining better knowledge, follow rules, and be ready for any challenges in the future.

Selection of healthcare waste management treatment using fuzzy rough numbers and Aczel-Alsina Function

The COVID-19 pandemic led to an increase in healthcare waste (HCW). HCW management treatment needs to be re-taken into focus to deal with this challenge. In practice, there are several treatments of HCW with their advantages and disadvantages. This study is conducted to select the appropriate treatment for HCW in the Brčko District of Bosnia and Herzegovina. Six HCW management treatments are analyzed and observed through twelve criteria. Ten-level linguistic values were used to bring this evaluation closer to human thinking. A fuzzy rough approach is used to solve the problem of inaccuracy in determining these values. The OPA method from the Bonferroni operator is used to determine the weights of the criteria. The results of the application of this method showed that the criterion Environmental Impact ( C 4 ) received the highest weight, while the criterion Automation Level ( C 8 ) received the lowest value. The ranking of HCW management treatments was performed using MARCOS methods based on the Aczel-Alsina function. The results of this analysis showed that the best-ranked HCW management treatment is microwave (A6) while landfill treatment (A5) is ranked worst. This study has provided a new approach based on fuzzy rough numbers where the Bonferroni function is used to determine the lower and upper limits, while the application of the Aczel-Alsina function reduced the influence of decision-makers on the final decision because this function stabilizes the decision-making process.

Logistics performance: critical factors in the implementation of end-of-life management practices in the pharmaceutical care process

The management of healthcare waste and end-of-life medication coming from different sources are primary challenges faced by public health leaders. Several factors may be considered critical and inhibitive to reverse logistics within the context of waste management processes. If those factors are not addressed, they may become obstacles to reverse logistics implementation. The purpose of this study is to evaluate the effect that critical factors play in the adoption of end-of-life management practices for medication and its influence on logistics performance. Literature provided some critical factors: management factor, collaboration factor, information technology factor, infrastructure factor, politics factor, financial and economic factor, end-of-life management practices, and logistics performance factor. A sample of 67 professionals from the public pharmaceutical care process answered a structured questionnaire. The collected data was analyzed using partial least square-structural equation modeling. The theoretical structural test confirmed eleven out of the fifteen hypotheses considered. The results have indicated that end-of-life management practices exert a direct influence on logistics performance. The analysis confirmed a direct effect of the information technology factor on end-of-life management practices, but not a moderation effect. Findings have contributed to the literature by providing deeper insights into the relationship between end-of-life management practices for medicines and logistics performance. Moreover, it supports health managers' decision-making in the pharmaceutical care process improvement and engagement with solid waste management policies.

Waste management beyond the COVID-19 pandemic: Bibliometric and text mining analyses

The outbreak of the COVID-19 pandemic has significantly increased the demand for personal protective equipment, in particular face masks, thus leading to a huge amount of healthcare waste generated worldwide. Consequently, such an unprecedented amount of newly emerged waste has posed significant challenges to practitioners, policy-makers, and municipal authorities involved in waste management (WM) systems. This research aims at mapping the COVID-19-related scientific production to date in the field of WM. In this vein, the performance indicators of the target literature were analyzed and discussed through conducting a bibliometric analysis. The conceptual structure of COVID-19-related WM research, including seven main research themes, were uncovered and visualized through a text mining analysis as follows: (1) household and food waste, (2) personnel safety and training for waste handling, (3) sustainability and circular economy, (4) personal protective equipment and plastic waste, (5) healthcare waste management practices, (6) wastewater management, and (7) COVID-19 transmission through infectious waste. Finally, a research agenda for WM practices and activities in the post-COVID-19 era was proposed, focusing on the following three identified research gaps: (i) developing a systemic framework to properly manage the pandemic crisis implications for WM practices as a whole, following a systems thinking approach, (ii) building a circular economy model encompassing all activities from the design stage to the implementation stage, and (iii) proposing incentives to effectively involve informal sectors and local capacity in decentralizing municipal waste management, with a specific focus on developing and less-developed countries.

Waste audits in healthcare: A systematic review and description of best practices

Healthcare generates large amounts of waste, harming both environmental and human health. Waste audits are the standard method for measuring and characterizing waste. This is a systematic review of healthcare waste audits, describing their methods and informing more standardized auditing and reporting. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched MEDLINE, Embase, Inspec, Scopus and Web of Science Core Collection databases for published studies involving direct measurement of waste in medical facilities. We screened 2398 studies, identifying 156 studies for inclusion from 37 countries. Most were conducted to improve local waste sorting policies or practices, with fewer to inform policy development, increase waste diversion or reduce costs. Measurement was quantified mostly by weighing waste, with many also counting items or using interviews or surveys to compile data. Studies spanned single procedures, departments and hospitals, and multiple hospitals or health systems. Waste categories varied, with most including municipal solid waste or biohazardous waste, and others including sharps, recycling and other wastes. There were significant differences in methods and results between high- and low-income countries. The number of healthcare waste audits published has been increasing, with variable quality and general methodologic inconsistency. A greater emphasis on consistent performance and reporting standards would improve the quality, comparability and usefulness of healthcare waste audits.

Equity in water, sanitation, hygiene, and waste management services in healthcare facilities in Tanzania

Objectives

To determine coverage and the reliability of water, sanitation, hygiene (WASH) and healthcare waste management (HCWM) services in healthcare facilities (HCFs) in Tanzania.

Study design

Cross-sectional study design.

Methods

Data of 1066 HCFs in Tanzania from the 2014-15 Tanzania Service Provision Assessment (TSPA) survey were analyzed. The availability of WASH and HCWM services was examined across facility locations, types, and managing authorities. Descriptive statistics, and bivariate and multivariate logistic regression analyses were performed.

Results

HCFs with improved water sources, with functional improved latrines for patients, and using the incineration method to treat sharps waste before final disposal were 81.2%, 70.6%, and 41.3%, respectively. Among the HCFs with improved water sources and with functional improved latrines for patients, 50.9% and 50.6% respectively experienced water outages. Rural HCFs were less likely to have water sources on-site within 500 m (AOR 0.41; 95%CI 0.24-0.68), and soap, running water or alcohol-based hand rub (AOR 0.54; 95%CI 0.37-0.80). Rural HCFs were 0.25 times less likely to have functioning improved latrines for patients than urban HCFs (p < 0.001). Public HCFs were 0.5 times less likely to have an incineration method for sharps waste treatment than private HCFs (p < 0.001).

Conclusion

Access inequity in WASH and HCWM was observed in HCFs in rural areas and those under public management. To attain equity and sustainability, investing in improving WASH and HCWM services for both new and renovations projects, must consider the circumstance status of the marginalized society.

Impact of COVID-19 on healthcare waste generation: Correlations and trends from a tertiary hospital of a developed country

The SARS-CoV-2 (COVID-19) coronavirus pandemic has represented an emergency not only from a clinical point of view, but also for the environment due to the largely increased waste disposal. This study aimed at estimating, in the context of current trends, the increase in healthcare waste (HW) generation during the outbreak, based on data from a tertiary hospital. From the purveying office statements of 'SS Antonio e Biagio e Cesare Arrigo' Hospital of Alessandria (Italy), monthly HW generation data from January 2015 to March 2021 were retrospectively retrieved. Trends and COVID's impact were evaluated by Interrupted Time Series (ITS) design with linear regression models. Locally Weighted Scatterplot Smoothing was used to model the relation between infectious HW generation and proportion of COVID-related bed days. HW generation rose from 35.9 ± 3.8 tonnes month^-1 (2.4 ± 0.2 kg per patient-day, kg PD^-1) in 2015-2019, to 46.3 ± 6.0 tonnes month^-1 (3.3 ± 0.7 kg PD^-1) during the outbreak. The increasing trend was not appreciably modified as for its slope (p = 0.363), while a significant level change was found between baseline and outbreak (+ 0.72 kg PD^-1, p < 0.001). The proportion of COVID-related bed days non-linearly affected the infectious HW generated per patient-day, with steeper increases for proportions above 20%. The study showed a significant rise in HW generation in 2020-2021, reasonably due to the COVID outbreak; in addition, the generally increasing trend was not affected. Therefore, urgent measures are needed to conciliate safety requirements with HW generation issues.

Locating a disinfection facility for hazardous healthcare waste in the COVID-19 era: a novel approach based on Fermatean fuzzy ITARA-MARCOS and random forest recursive feature elimination algorithm

Hazardous healthcare waste (HCW) management system is one of the most critical urban systems affected by the COVID-19 pandemic due to the increase in waste generation rate in hospitals and medical centers dealing with infected patients as well as the degree of hazardousness of generated waste due to exposure to the virus. In this regard, waste network flow would face severe problems without taking care of hazardous waste through disinfection facilities. For this purpose, this study aims to develop an advanced decision support system based on a multi-stage model that was combined with the random forest recursive feature elimination (RF-RFE) algorithm, the indifference threshold-based attribute ratio analysis (ITARA), and measurement of alternatives and ranking according to compromise solution (MARCOS) methods into a unique framework under the Fermatean fuzzy environment. In the first stage, the innovative Fermatean fuzzy RF-RFE algorithm extracts core criteria from a finite set of initial criteria. In the second stage, the novel Fermatean fuzzy ITARA determines the semi-objective importance of the core criteria. In the third stage, the new Fermatean fuzzy MARCOS method ranks alternatives. A real-life case study in Istanbul, Turkey, illustrates the applicability of the introduced methodology. Our empirical findings indicate that "Pendik" is the best among five candidate locations for sitting a new disinfection facility for hazardous HCW in Istanbul. The sensitivity and comparative analyses confirmed that our approach is highly robust and reliable. This approach could be used to tackle other critical multi-dimensional problems related to COVID-19 and support sustainability and circular economy.

An assessment tool for healthcare waste management in Brazilian municipalities during the COVID-19 pandemic

The COVID-19 pandemic has put healthcare waste management (HCWM) systems under pressure worldwide. In Brazil, where municipalities routinely experience challenges in ensuring suitable disposal of healthcare waste (HCW), the pandemic has made this even more challenging. Therefore, the creation of tools and methods to help in municipal HCWM during the COVID-19 pandemic is of utmost importance. This article presents the development of a tool to evaluate HCWM in Brazilian municipalities during the pandemic. Following guidelines of health agencies, 56 indicators and 18 criteria were selected to create a tool called the municipal healthcare waste management assessment index (iMHWaste). These indicators and criteria were divided into operational, environmental, political-economic, educational and social groups. Each group considers essential aspects for sustainable management, safety and reduced spread of coronavirus. The analytic hierarchy process was used to assign the weights attributed to the groups and criteria. The indicators can be measured according to a standardized rating scale proposed for each one. These elements were aggregated with a weighted linear combination, into an equation that allows the calculation of the iMHWaste. The index is rated on a scale of 0-1. The index was applied in a Brazilian municipality considering a pre-pandemic HCWM. With the identification of the municipality's management weaknesses, it was possible to identify the main actions that should be prioritized in the transition from traditional HCWM during the pandemic.

Healthcare waste generation in hospitals per continent: a systematic review

There are increasing worldwide concerns about the negative impacts of healthcare waste generated in hospitals, especially in low- and middle-income countries. Hazardous type of waste can contribute to adverse effects both in human populations and the environment because of its physical, chemical, and biological characteristics. A comprehensive view on increasing waste in the world has not been conducted to understand the breadth of the issue; thus, this paper sought to provide an analysis of hospitals' healthcare waste generation rate. Comparisons were made with Wilcoxon and Kruskal-Wallis tests for simple and multiple comparisons, to analyze nonparametric data, with post hoc by Nemenyi test. Median values indicated that hospital waste was the highest in North and South America (4.42, 1.64 kg/bed/day, respectively) and was almost nonexistent in Oceania (0.19 kg/bed/day), while the median rates for hazardous waste were the highest in Oceania (0.77 kg/bed/day). Africa was almost the lowest producer of waste in each category (0.19 and 0.39 kg/bed/day for hospital and hazardous waste, respectively). Over time, linear regression indicated that hazardous waste in Asia and Europe has increased, while in Oceania, the total waste also increased. Interestingly, in North America, it was observed a reduction in the generation for both total and hazardous waste. This information highlights the importance of understanding continent-specific characteristics and rates, which can be used to create a more individualized approach to addressing healthcare waste in the world.

Mapping healthcare waste management research: Past evolution, current challenges, and future perspectives towards a circular economy transition

Improper healthcare waste (HCW) management poses significant risks to the environment, human health, and socio-economic sustainability due to the infectious and hazardous nature of HCW. This research aims at rendering a comprehensive landscape of the body of research on HCW management by (i) mapping the scientific development of HCW research, (ii) identifying the prominent HCW research themes and trends, and (iii) providing a research agenda for HCW management towards a circular economy (CE) transition and sustainable environment. The analysis revealed four dominant HCW research themes: (1) HCW minimization, sustainable management, and policy-making; (2) HCW incineration and its associated environmental impacts; (3) hazardous HCW management practices; and (4) HCW handling and occupational safety and training. The results showed that the healthcare industry, despite its potential to contribute to the CE transition, has been overlooked in the CE discourse due to the single-use mindset of the healthcare industry in the wake of the infectious, toxic, and hazardous nature of HCW streams. The findings shed light on the HCW management domain by uncovering the current status of HCW research, highlighting the existing gaps and challenges, and providing potential avenues for further research towards a CE transition in the healthcare industry and HCW management.

Generation of infectious waste during the COVID-19 pandemic: The case of a Brazilian hospital

Coronavirus-19 disease (COVID-19) acquired pandemic status in March 2020. The new virus has caused serious implications in the healthcare services management, including several sectors, among them the generation of waste. Healthcare wastes (HCW) generation increased along pandemic representing a health problem due to potentially infected ones. From this perspective, the study sought to analyse the challenges and changes imposed by COVID-19 in the HCW management in a large public hospital from Brazil. For this purpose, data about the Contingency Plan prepared by the hospital and HCW generation from 2017 to 2020 were used, analysed by statistical methods. When dealing with the Contingency Plan, the Brazilian hospital adopted measures similar to other hospitals around the world as described by the literature, such as: adoption of new protocols, specific team assigned to manage actions and training of professionals and suspension of elective surgeries. Regarding the generation of HCW, there was a significant increase in the mass of biological waste with a high risk of infection. The waste of this group increased from March 2020, coinciding with the start of care for the patients infected by COVID-19. The contribution of this type of waste to total generation jumped from approximately 0.2% in previous years to almost 5% in 2020. In addition, a reduction in the average of total waste generated in kilogrammes per bed per day from 2017 to 2019 was indicated compared to the 2020. COVID-19 pandemic led to major challenges for hospitals that had to care for patients infected with the SARS-CoV-2 virus, including new protocols, changing the work shifts and training the teams in the new procedures. The biological waste with a high risk of infectiousness also increased 30 times.

Assessing the management of healthcare waste for disease prevention and environment protection at selected hospitals in Kinshasa, Democratic Republic of Congo

Incineration is the most used healthcare waste (HCW) disposal method. Disease outbreaks due to Ebola virus and SARS-CoV2 require attention to HCW management to avoid pathogens spread and spillover. This study describes HCW management prior to incineration and hospital incinerators performance by analysing bottom ashes from hospitals in Kinshasa, Democratic Republic of Congo. We used semi-structured interviews to capture information on pre-incineration waste management and analysed the chemical composition of 27 samples of incinerator bottom ashes using the energy dispersive X-ray fluorescence. Neither sorting nor waste management measures were applied at hospitals surveyed. Incinerator operators were poorly equipped and their knowledge was limited. The bottom ash concentrations of cadmium, chromium, nickel and lead ranged between 0.61-10.44, 40.15-737.01, 9.11-97.55 and 16.37-240.03 mg kg^-1, respectively. Compared to Chinese incinerator performance, the concentrations of some elements were found to be lower than those from China. This discrepancy may be explained by the difference in the composition of HCW. The authors conclude that health care waste in Kinshasa hospitals is poorly managed, higher concentrations of heavy metals are found in incinerator bottom ashes and the incinerators quality is poor. They recommend the strict application of infection prevention control measures, the training of incinerator operators and the use of high-performance incinerators.

Bi-Objective Adaptive Large Neighborhood Search Algorithm for the Healthcare Waste Periodic Location Inventory Routing Problem

There has been an unexpected increase in the amount of healthcare waste during the COVID-19 pandemic. Managing healthcare waste is vital, as improper practices in the waste system can lead to the further spread of the virus. To develop effective and sustainable waste management systems, decisions in all processes from the source of the waste to its disposal should be evaluated together. Strategic decisions involve locating waste processing centers, while operational decisions deal with waste collection. Although the periodic collection of waste is used in practice, it has not been studied in the relevant literature. This paper integrates the periodic inventory routing problem with location decisions for designing healthcare waste management systems and presents a bi-objective mixed-integer nonlinear programming model that minimizes operating costs and risk simultaneously. Due to the complexity of the problem, a two-step approach is proposed. The first stage provides a mixed-integer linear model that generates visiting schedules to source nodes. The second stage offers a Bi-Objective Adaptive Large Neighborhood Search Algorithm (BOALNS) that processes the remaining decisions considered in the problem. The performance of the algorithm is tested on several hypothetical problem instances. Computational analyses are conducted by comparing BOALNS with its other two versions, Adaptive Large Neighborhood Search Algorithm and Bi-Objective Large Neighborhood Search Algorithm (BOLNS). The computational experiments demonstrate that our proposed algorithm is superior to these algorithms in several performance evaluation metrics. Also, it is observed that the adaptive search engine increases the capability of BOALNS to achieve high-quality Pareto-optimal solutions.

Secondary overtriage of isolated facial trauma

DESIGN

Retrospective chart review.

SETTING

Academic, tertiary care, level I trauma center in a rural state.

BACKGROUND

Unnecessary transfer of certain facial trauma patients results in a burden of time, money, and other resources on both the patient and healthcare system; identification and development of outpatient treatment pathways for these patients is a significant opportunity for cost savings.

OBJECTIVES

To investigate the treatment and disposition of un-complicated, stable, isolated facial trauma injuries transferred from outside hospitals and determine the significance of secondary overtriage.

METHODS

Retrospective chart review utilizing our institutional trauma database, including patients transferred to our emergency department between January 2012 and December 2017. Patients were identified by ICD9 or ICD10 codes and only those with isolated facial trauma were included.

RESULTS

We identified 538 isolated facial trauma patients who were transferred to our institution during the study period. The majority of those patients were transferred via ground ambulance for an average of 76 miles. Overall, 82% of patients (N = 440) were discharged directly from our institution's emergency department. Almost 30% of patients did not require any formal treatment for their injuries; the potential savings associated with elimination of these unnecessary transfers was estimated to be between $388,605 and $771,372.

CONCLUSIONS

We identified a high rate of patients with stable, isolated facial trauma that could potentially be evaluated and treated without emergent transfer. The minimization of these unnecessary transfers represents a significant opportunity for cost and resource utilization savings.

Capacity assessment and implementation analysis of common treatment facility for the management of infectious healthcare waste in rapidly urbanising city of Nepal

This study is one of the first systematic attempts to examine the possibility of a common treatment facility (CTF) to treat infectious healthcare waste (HCW) in Nepal. First, the survey was conducted in 14 healthcare facilities (HFs) ranging from health posts to large hospitals selected from 120 total HFs in Nepalgunj sub-metropolitan city (SMC), a rapidly urbanising city of Nepal to investigate the current practices of HCW management (HCWM) and to estimate the waste generation and characteristics in the different HFs. The result shows that the average unit waste generation rate for health posts, clinics, urban health centres, and hospitals was estimated at 1.397 kg day^-1, 1.608 kg day^-1, 0.178 kg day^-1 and 1.818 kg bed^-1 day^-1, respectively. Of the total 1242 kg day^-1 HCW generated in Nepalgunj SMC, 73% is infected in the current situation, but if fully sorted at source, only 32% of the waste will be infected. Based on these HCW generation data and fraction of infectious waste, including waste management practices, three different scenarios are proposed for the capacity assessment and designing implementation modality of the CTF to treat infectious waste from all HFs of Nepalgunj SMC as a case study where an integrated solid waste management facility including material recovery facility and sanitary landfill site for municipal solid waste management is already in operation. The different implementation analyses are discussed, and the best implementation arrangement has been recommended for the sustainability of the project. This approach can be replicated in other cities alone or regions with many neighbouring cities of Nepal and explores a workable solution for HCWM in the rapidly urbanising cities of developing countries to help them improve their condition.

Challenges and actions to the environmental management of Bio-Medical Waste during COVID-19 pandemic in India

The outbreak of COVID-19 has engendered a global health crisis along with diverse impacts on economy, society and environment. Efforts to combat this pandemic have also significantly shot-up the quantity of Bio-medical Waste (BMW) generation. Safe disposal of large quantity of BMW has been gradually posing a major challenge. BMW management is mostly implemented at municipal level following regulatory guidelines defined by respective states and the Union. This article is a narrative of the status of BMW generation, management and regulation in India in the context of COVID-19 crisis. The article is based on comparative analysis of data on BMW generation and management from authentic sources, a systematic literature review and review of news reports. In the current pandemic situation where media has been playing a significant role in highlighting all the concerns related to COVID-19 spread and management. Assessing the ground situation regarding effectiveness of prevailing BMW management facilities, requirement and suggestions can provide insights to the subject with policy implications for India and countries as well. The discussion has been built on different dimensions of BMW management during the pandemic including existing infrastructures, capacity utilisation, policy guidelines, operational practices and waste-handlers aspects. The results on state-wise analysis of reported BMW quantity and active COVID-19 patients also reveal some non-linear relationship between the two variables. Delhi, the National Capital is situated at a better position in terms of BMW management as compared to other studied states. The findings are expected to provide valuable insights to the policy makers and other relevant authorities to evaluate adequateness as well as efficiency quotients of entire BMW management landscape. Some of the critical observations of this article are also expected to offer impetus for enhancing national disaster preparedness in future.

The interplay of circular economy with industry 4.0 enabled smart city drivers of healthcare waste disposal

Generation of healthcare waste from different patient care activities in hospitals, pathology labs and research centres has been a matter of great concern for environmental and social bodies across the world. This concern comes from its infectious and hazardous nature which brings life taking disease such as human immunodeficiency virus and Hepatitis-B. Moreover, with the outbreak of corona virus disease 2019 (COVID-19) pandemic across the world, healthcare waste has become even more infectious like never before and showing its potential for claiming lives if not disposed properly. Additionally, the COVID-19 has put up another challenge in terms of exponentially increasing demand for personal protective equipments for healthcare workers such as doctors, nurses, ward boys, and sanitation workers. In this paper, seven criteria related to smart healthcare waste disposal system infused by circular economy aspects to recover value from disposables are identified and analysed using a decision making trial and evaluation laboratory (DEMATEL) method. The criteria have been prioritized by its importance and net cause and effect relationship through a causal diagram. Two criteria, (i) digitally connected healthcare centres, waste disposal firms and pollution control board, and (ii) providing a pollution control board's feedback app to public and other stakeholders, feature as strong reasons for a smart healthcare waste disposal system. Conclusively, this study provides a causal relationship model among the intertwined drivers of industry 4.0 and circular economy for developing a smart healthcare waste disposal system enriched with the benefits of circular economy.

An evaluation of the management of offensive waste from the National Health Service in England: A case study approach

In the UK, the majority of offensive waste is disposed of at landfills. However, producers have a duty of care under the Waste Hierarchy to divert waste away from landfill. Using case studies from the East of England, the East Midlands and West Midlands in England, this study sought to quantify the waste arisings disposed of to landfill and to understand the reasons why. The findings show that offensive waste arisings, treatment method and costs varied by region, only a fraction of the waste disposed of to landfill in the East of England, compared with the majority being disposed of to landfill in the East Midlands and West Midlands. Despite the financial implications of landfilling being the lowest cost per tonne option, the key barriers to moving away from disposal to landfill was a lack of available alternatives, and it being the only option offered by the waste contractor.

Adherence to safety practices and risks associated with health care waste management at an academic hospital, Pretoria, South Africa

Background

Adequate knowledge on hazards of healthcare waste and proper handling methods can result in its safe disposal and protection of workers and communities. The study assessed perceptions of healthcare workers on the adherence and risks associated with the practices of healthcare waste management.

Methods

A total of 126 questionnaires were administered in selected wards at an academic hospital to establish training and knowledge on legislations regarding healthcare waste and health hazards associated with such waste.

Results

Sixty nine percent (69.0%) of participants had received training on healthcare waste handling. The highest number of cleaning staff (85.7%) received training from work while 34.8% of the doctors also received training from work. Only 44.1% of the nurses had knowledge about policies on healthcare waste. The majority of the participants (82.0%) had knowledge on the risks associated with handling of healthcare waste. However, only 20.0% of the participants re-capped needles after use and of these 43.5% were doctors. Most of the nurses (64.0%) had been exposed to needle pricks.

Conclusion

Even though 82.0% of the participants believed there were enough management practices enforced with regards to the healthcare waste, it was recommended that there should be more education on the handling of healthcare waste.

Medical waste management at three hospitals in Jenin district, Palestine

Medical wastes are considered hazardous because they may possess infectious agents and can cause unsafe effects on the environment and human health. This study is to analyze and evaluate the current status of medical waste management at Jenin's district in light of medical waste control regulations recommended by the World Health Organization. The results demonstrated that the average hazardous healthcare waste generation rate ranges from 0.54 to 1.82 kg/bed/day with a weighted average of 0.78 kg/bed/day. There was no established waste segregation of healthcare waste types in all hospitals, and these wastes were finally disposed of in a centralized municipal sanitary landfill, namely Zahrat Al-Finjan. The results suggest that there is a need for activation and enforcement of medical waste laws. This can be achieved through cooperation among key actors: Ministry of Health, Environmental Quality Authority, Ministry of Local Government, and Non-Governmental Organizations working in related fields. Additional remediation measures proposed to tackle the problematic areas of medical waste management in Jenin's district hospitals are addressed. Some recommendations to minimize potential health and environmental risks of medical waste are also introduced.

Self-reported healthcare waste segregation practice and its correlate among healthcare workers in hospitals of Southeast Ethiopia

BACKGROUND

The key to the effective management of healthcare wastes is segregation of the waste at the point of generation; no matter what final strategy for treatment and disposal of wastes is selected, it is critical that waste streams are separated. In Ethiopia, healthcare waste segregation practice among healthcare workers is overlooked and scarcely addressed in the scientific literature. This hospital-based cross-sectional study was, therefore, conducted to assess healthcare waste segregation practice and its correlate among healthcare workers in Bale zone, southeast Ethiopia.

METHODS

All five hospitals found in Bale zone were included and the study participants were selected using a systematic sampling technique from each hospital. Data were collected through interview using structured questionnaires. Descriptive statistics were computed. Bivariate and multivariable logistic regression analyses were employed to identify factors that correlate with healthcare waste segregation practice.

RESULTS

A total of four hundred and nine healthcare workers participated in the study, for a response rate of 97.4%. Of these, 220(53.8%) (95% CI: 49.1-58.9) of healthcare workers were found to have reported good healthcare waste segregation practice. Being male gender (AOR = 1.70, 95%CI: 1.04-2.78), less than 30 years of age (AOR = 2.02, 95%CI: 1.06-3.84), less than 2 years work experience (AOR = 2.95, 95%CI: 1.39-6.26), having good self-reported standard precaution practice (AOR = 8.47,95%CI:4.98-14.42), and working in a department with an on-site healthcare waste segregation container (AOR = 2.10, 95%CI:1.24-3.55) were factors that correlated with self-reported healthcare waste segregation practice.

CONCLUSION

Overall, only half of the healthcare workers had good healthcare waste segregation practice, which is low and unsatisfactory. Less service year, having good standard precaution practice, and the presence of onsite waste segregation container were the most important variables that correlate with self-reported healthcare waste segregation practice. Therefore, to improve healthcare waste segregation practice health authorities should focus on sufficient allocation of onsite waste receptacles. In addition, periodic training on standard precaution will improve compliance with segregation practice.

Profile of highly infected wastes generated by hospitals: A case in Belo Horizonte, Brazil

Healthcare wastes are generated in facilities whose activities are related to human or animal healthcare. Wastes with high infectious potential risk to human health and the environment must be managed carefully, from generation to its final disposal. However, there is an absence of consolidated data addressing the healthcare waste qualitative classification generated by hospitals of a large city. Therefore, the present study aims to characterise qualitatively the high infectious waste generated by hospitals from Belo Horizonte city, Brazil, whose Health Services Waste Management Plan were approved and certificated by the municipal cleansing autarchy. Differences in the types of infectious wastes generated in maternity hospitals were identified ( p 0.034), when compared with general ( p 0.189), low ( p 0.549) and high complexity ( p 0.619), which can be explained owing to the extended hospital activities. This information suggests a similar profile of the qualitative generation of infectious wastes by hospital categories, as expected. The largest generation and diversity of high-infected wastes are associated with a greater variety of activities provided. The segregation can be considered as the main step in healthcare waste management, therefore, it is concluded that the correct classification leads to a better understanding of all those involved in the healthcare waste management.

Healthcare waste management current status and potential challenges in Ethiopia: a systematic review

Objective

During the healthcare delivery process, hazardous wastes can be generated from the health facilities. Improper healthcare waste management is responsible for the transmission of more than 30 dangerous bloodborne pathogens. The aim of this systematic review was to evaluate the healthcare waste management practice and potential challenges in Ethiopia.

Results

Electronic databases and direct Google search yielded 1742 articles from which 17 studies met the inclusion criteria. The proportion of hazardous waste generated in Ethiopian healthcare facilities was unacceptably high which ranged from 21 to 70%. Most studies indicated the absence of proper waste segregation practice at the source of generation. Treatment of the healthcare waste using low combustion incinerator and/or open burning and open disposal of the incinerator ash were very common. Lack of awareness from the healthcare staff, appropriate waste management utilities and enforcement from the regulatory bodies were mainly identified as a common factor shared by most of the studies. The healthcare waste management practice in Ethiopian healthcare facilities was unsatisfactory. There should be close supervision of the waste disposal process by the regulatory bodies or other stakeholders.

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.

Health care waste management among health workers and associated factors in primary health care facilities in Kampala City, Uganda: a cross-sectional study

BACKGROUND

Healthcare wastes (HCWs) are one of the most hazardous wastes globally; second to only radiation waste. HCW management needs to be prioritized because of the devastating effects on human health and environment if not well managed. Health workers play a crucial role in management of HCWs. This study investigated the management of HCWs among health workers and associated factors in primary health care facilities in Kampala City, Uganda.

METHODS

We conducted a cross-sectional health facility survey in 8 primary health care facilities in Kampala City from March to April 2017. We interviewed health workers who provided data on socio-demographic characteristics, knowledge, attitudes and practices on HCW management. Prevalence ratios (PRs) and their corresponding 95% confidence intervals were used as a measure of association between HCW management and associated factors. The PRs were obtained using a multivariable modified Poisson regression using a generalized linear model of Poisson family with a logarithm as the canonical link function, with robust standard errors while applying a forward elimination method.

RESULTS

A total of 200 health workers responded to the survey; Knowledge of HCW management  was high 143 (71.5%, 95% CI (65.2-77.8)). About 160 (80.0%) wore appropriate personal protective wear when handling HCWs. Overall, 148 (74.0%, 95% CI (67.8-80.1) had satisfactory HCW management practices. Health workers with diploma education (Adjusted PR = 1.49, 95% CI (1.13-1.96), working in the teenage corner (Adjusted PR = 1.10, 95% CI (1.01-1.29), previous training on HCW management (Adjusted PR = 1.19, 95% CI (1.01-1.42) and those who thought HCW management was important (Adjusted PR = 2.81, 95% CI (1.22-6.47) were more likely to have satisfactory HCW management practices.

CONCLUSION

The practices of health workers on HCW management were largely satisfactory. Higher odds of HCW management were determined among health workers with diploma education, previous HCW management trainings and among those who perceived HCW management as important. There is need to organize HCW management trainings in order to improve their HCW management practices among health workers.

Assessment of Healthcare Waste Generation Rate and Its Management System in Health Centers of Bench Maji Zone

Background

It is known that the basic role of healthcare system is to preserve the health of patients and protect the public from diseases. However, in the process of performing these activities, health facilities generate hazardous waste that could be potentially harmful to healthcare workers, the public and the environment if there is insufficient handling, treatment and disposal of those wastes. Unfortunately, healthcare waste management is, in many regions, not yet carried out with a satisfactory degree of safety. Therefore, the aim of this study was to assess healthcare waste generation rate and its management system in health centers of Bench Maji Zone.

Methods

A cross-sectional study was conducted from February to August, 2016. Observational checklist, key informant interview guide and weight scale were used to assess healthcare waste generation rate and its management system in selected health centers. Training, pre-test, instrument calibration and daily meeting were used to improve data quality. The Data was entered, compiled and analyzed using EpiData version 3.1 and SPSS version 21. The results on waste management system were reported using different descriptive statistics.

Results

Out of the total HCW generated in health centers, more than half (57.9%) was general or non-risk HCW, and the remaining 42.1% was hazardous healthcare waste. The amount of HCW generated in the studied health centers was different from WHO's norm which may be attributed to different factors such as economy, patient flow, difference in services provided, poor waste segregation practice, available waste management system and seasonal factors.

Conclusion

HCW was not adequately managed which is characterized by lack of HCW segregation at source of generation and inadequate facilities to manage HCW. Therefore, it is important to develop a HCW management plan for keeping human health as well environmental sustainability.

Knowledge and Practice of Health Workers about Healthcare Waste Management in Public Health Facilities in Eastern Ethiopia

Healthcare waste management (HWM) problems are growing with an ever-increasing number of hospitals, clinics, diagnostic laboratories, etc in Ethiopia. Health workers are one of the key personnel who are responsible for the proper management of healthcare wastes at any health facilities. However, this performance will depend the level of knowledge and practice regarding waste management. A facility based cross-sectional study design was applied on 400 health workers. All public health institutions inside Jigjiga town were included and the study participants were randomly selected from each health facility. Data were collected using pre-tested and self administered questionnaire. The collected data was analyzed using SPSS version 20. Multivariable logistic regression model was used to identify factors associated with knowledge and practice of health workers. Out of those involved in this study, 47.7% and 42.3% of respondents had good knowledge and good practice on healthcare waste management, respectively. Health workers in the age group of 35-44 years, nurses, midwifes, medical laboratory, were significantly associated with knowledge of health workers. On the other hand, only educational status was significantly associated with practice. In this study, both knowledge and practice of health workers about healthcare waste management was poor. To enhance both the knowledge and practice of health workers, on job training is recommended.

Use of urinary biomarkers to characterize occupational exposure to BTEX in healthcare waste autoclave operators

Urinary benzene, toluene, ethylbenzene, and xylenes (BTEX) can be used as a reliable biomarker of exposure to these pollutants. This study was aimed to investigate the urinary BTEX concentration in operators of healthcare waste (HCW) autoclaves. This cross-sectional study was conducted in selected hospitals in Tehran, Iran between April and June 2017. Twenty operators (as the case group) and twenty control subjects were enrolled in the study. Personal urine samples were collected at the beginning and end of the work shift. Urinary BTEX were measured by a headspace gas chromatography-mass spectrometry (GC/MS). A detailed questionnaire was used to gather information from subjects. Results showed that the median of urinary benzene, toluene, ethylbenzene, m-p xylene, and o-xylene levels in the exposed group were 3.26, 3.36, 0.84, 3.94 and 4.48 μg/L, respectively. With the exception of ethylbenzene, subjects in the exposed group had significantly higher urinary BTEX levels than control group (p < 0.05). Urinary BTEX concentrations in the exposed case group were 2.5-fold higher than in the control group. There was a significant relationship between the amount of generated waste per day and the urinary BTEX in the exposed group. Smoking status and type of autoclave used were also identified as predictors of urinary BTEX concentrations. The healthcare waste treatment autoclaves can be considered as a significant BTEX exposure source for operators working with these treatment facilities. The appropriate personal protection equipment and control measures capable in reducing BTEX exposure should be provided to HCW workers to reduce their exposures to BTEX.

Results of a Quality Improvement Project Aimed at Eliminating Healthcare Waste by Changing Medical Resident Test Ordering Behavior

Background

In light of rising healthcare costs and evidence of inefficient use of medical resources, there is growing interest in reducing healthcare waste by clinicians. Unwarranted lab tests may lead to further tests, prolonged hospital stays, unnecessary referrals and procedures, patient discomfort, and iatrogenic anemia, resulting in significant economic and clinical effects. Blood tests are essential in guiding medical decisions, but they are also associated with significant financial and clinical costs. We designed a quality improvement study that attempted to decrease inappropriate ordering of laboratory tests while maintaining quality of care in a large residency program.

Methods

An algorithm outlining indications for complete blood count (CBC), coagulation profile (PT/INR) and basic metabolic profile (BMP) was created by the study team. Data from 1,312 patients over a 3-month period in the pre-intervention phase and 1,255 patients during the selected intervention phase were analyzed. The primary endpoint was mortality rate and secondary endpoints were length of stay and laboratory costs.

Results

There were significant decreases in the number of PT/INR orders (20.6%), followed by BMP orders (12.4%), and CBC orders (9.3%). The mortality rate was 5.3% for the pre-intervention phase and 5.8% for the selected intervention phase, with a difference of 0.5% (P = 0.44).

Conclusion

Our approach leads to a decrease in costs, preventing unnecessary downstream testing, and improving patient experience. It also brought a mental discipline while ordering blood tests amongst residents.

Solid medical waste: a cross sectional study of household disposal practices and reported harm in Southern Ghana

Background

Solid medical waste (SMW) in households is perceived to pose minimal risks to the public compared to SMW generated from healthcare facilities. While waste from healthcare facilities is subject to recommended safety measures to minimize risks to human health and the environment, similar waste in households is often untreated and co-mingled with household waste which ends up in landfills and open dumps in many African countries. In Ghana, the management of this potentially hazardous waste stream at household and community level has not been widely reported. The objective of this study was to investigate household disposal practices and harm resulting from SMW generated in households and the community.

Methods

A cross-sectional questionnaire survey of 600 households was undertaken in Ga South Municipal Assembly in Accra, Ghana from mid-April to June, 2014. Factors investigated included socio-demographic characteristics, medication related practices, the belief that one is at risk of diseases associated with SMW, SMW disposal practices and reported harm associated with SMW at home and in the community.

Results

Eighty percent and 89% of respondents discarded unwanted medicines and sharps in household refuse bins respectively. A corresponding 23% and 35% of respondents discarded these items without a container. Harm from SMW in the household and in the community was reported by 5% and 3% of respondents respectively. Persons who believed they were at risk of diseases associated with SMW were nearly three times more likely to report harm in the household (OR 2.75, 95%CI 1.15–6.54).

Conclusion

The belief that one can be harmed by diseases associated with SMW influenced reporting rates in the study area. Disposal practices suggest the presence of unwanted medicines and sharps in the household waste stream conferring on it hazardous properties. Given the low rates of harm reported, elimination of preventable harm might justify community intervention.

Environmental audits and process flow mapping to assess management of solid waste and wastewater from a healthcare facility: an Italian case study

In Europe, there are an increasing number of policy and legislative drivers for a more sustainable approach to the management of natural resources as well as for the mitigation of environmental health risks. However, despite significant progress in recent years, there is still some way to go to achieve circularity of process, as well as risk mitigation within organisations. Using a case study of the Gardone Val Trompia hospital in northern Italy, this manuscript offers a novel holistic examination of strategies to enhance resource efficiency and environmental health within a key sector, i.e. the healthcare sector. Through the use of environmental audits and process flow mapping, trends in waste and wastewater arisings and the associated financial and environmental costs and risks were identified. Recommendations for developing more resource efficient approaches as well as mitigating the environmental and public health risks are suggested. These include strategies for improved resource efficiency (including reduction in the hazardous waste) and reduced environmental impacts during the containment, transport and treatment of the waste.

Healthcare waste management during disasters and its effects on climate change: Lessons from 2010 earthquake and cholera tragedies in Haiti

Despite growing effects of human activities on climate change throughout the world, and global South in particular, scientists are yet to understand how poor healthcare waste management practices in an emergency influences the climate change. This article presents new findings on climate change risks of healthcare waste disposal during and after the 2010 earthquake and cholera disasters in Haiti. The researchers analysed quantities of healthcare waste incinerated by the United Nations Mission in Haiti for 60 months (2009 to 2013). The aim was to determine the relationship between healthcare waste incinerated weights and the time of occurrence of the two disasters, and associated climate change effects, if any. Pearson product-moment correlation coefficient indicated a weak correlation between the quantities of healthcare waste disposed of and the time of occurrence of the actual emergencies (r (58) = 0.406, p = 0.001). Correspondingly, linear regression analysis indicated a relatively linear data trend (R² = 0.16, F (1, 58) = 11.42, P = 0.001) with fluctuating scenarios that depicted a sharp rise in 2012, and time series model showed monthly and yearly variations within 60 months. Given that the peak healthcare waste incineration occurred 2 years after the 2010 disasters, points at the need to minimise wastage on pharmaceuticals by improving logistics management. The Government of Haiti had no data on healthcare waste disposal and practised smoky open burning, thus a need for capacity building on green healthcare waste management technologies for effective climate change mitigation.

Assessment of health-care waste management in a humanitarian crisis: A case study of the Gaza Strip

Health-care waste management requires technical, financial and human resources, and it is a challenge for low- and middle income countries, while it is often neglected in protracted crisis or emergency situations. Indeed, when health, safety, security or wellbeing of a community is threatened, solid waste management usually receives limited attention. Using the Gaza Strip as the case study region, this manuscript reports on health-care waste management within the context of a humanitarian crisis. The study employed a range of methods including content analyses of policies and legislation, audits of waste arisings, field visits, stakeholder interviews and evaluation of treatment systems. The study estimated a production from clinics and hospitals of 683kg/day of hazardous waste in the Gaza Strip, while the total health-care waste production was 3357 kg/day. A number of challenges was identified including lack of clear definitions and regulations, limited accurate data on which to base decisions and strategies and poor coordination amongst key stakeholders. Hazardous and non-hazardous waste was partially segregated and treatment facilities hardly used, and 75% of the hazardous waste was left untreated. Recommendations for mitigating these challenges posed to patients, staff and the community in general are suggested. The outputs are particularly useful to support decision makers, and re-organize the system according to reliable data and sound assumptions. The methodology can be replicated in other humanitarian settings, also to other waste flows, and other sectors of environmental sanitation.

Developing models for the prediction of hospital healthcare waste generation rate

An increase in the number of health institutions, along with frequent use of disposable medical products, has contributed to the increase of healthcare waste generation rate. For proper handling of healthcare waste, it is crucial to predict the amount of waste generation beforehand. Predictive models can help to optimise healthcare waste management systems, set guidelines and evaluate the prevailing strategies for healthcare waste handling and disposal. However, there is no mathematical model developed for Ethiopian hospitals to predict healthcare waste generation rate. Therefore, the objective of this research was to develop models for the prediction of a healthcare waste generation rate. A longitudinal study design was used to generate long-term data on solid healthcare waste composition, generation rate and develop predictive models. The results revealed that the healthcare waste generation rate has a strong linear correlation with the number of inpatients (R(2) = 0.965), and a weak one with the number of outpatients (R(2) = 0.424). Statistical analysis was carried out to develop models for the prediction of the quantity of waste generated at each hospital (public, teaching and private). In these models, the number of inpatients and outpatients were revealed to be significant factors on the quantity of waste generated. The influence of the number of inpatients and outpatients treated varies at different hospitals. Therefore, different models were developed based on the types of hospitals.

Analysis of the healthcare waste management status in Tehran hospitals

BACKGROUND

Considering the importance of healthcare waste management, following the ratification of the Waste Management law in 2005 and the subsequent approval of its executive bylaw in 2006 and finally the healthcare waste management criteria passing by the parliament in 2008, a review on the status of healthcare waste management is needed to implement the mentioned law properly.

FINDINGS

In this retrospective study during six months period all public hospitals in Iran's capital city, Tehran, were selected to conduct the survey. Data collected through an expert-standardized questionnaire was analyzed by using SPSS software. The results of the current status of healthcare waste management in Tehran hospitals showed 5.6% of hospitals were ranked excellent, 50.7% good, 26.4% medium, and the 13.9% of hospitals were ranked weak and 3.5% ranked very poor.

CONCLUSIONS

The findings showed that appropriate technologies should be used to have better disposal stage. As the ratified criteria were not fully observed by all the selected hospitals, training courses and comprehensive program conducting by each hospital could be enjoyed as practical tools to implement the all stages of healthcare waste management properly.

The impact of regulatory compliance behavior on hazardous waste generation in European private healthcare facilities

This study empirically evaluates whether the increasingly large numbers of private outpatient healthcare facilities (HCFs) within the European Union (EU) countries comply with the existing European waste legislation, and whether compliance with such legislation affects the fraction of healthcare waste (HCW) classified as hazardous. To that end, this study uses data collected by a large survey of more than 700 small private HCFs distributed throughout Portugal, a full member of the EU since 1986, where 50% of outpatient care is currently dominated by private operators. The collected data are then used to estimate a hurdle model, i.e. a statistical specification in which there are two processes: one is the process by which some HCFs generate zero or some positive fraction of hazardous HCW, and another is the process by which HCFs generate a specific positive fraction of hazardous HCW conditional on producing any. Taken together, the results show that although compliance with the law is far from ideal, it is the strongest factor influencing hazardous waste generation. In particular, it is found that higher compliance has a small and insignificant effect on the probability of generating (or reporting) positive amounts of hazardous waste, but it does have a large and significant effect on the fraction of hazardous waste produced, conditional on producing any, with a unit increase in the compliance rate leading to an estimated decrease in the fraction of hazardous HCW by 16.3 percentage points.

Hospital generated waste: an assessment of the awareness of hospital staff

BACKGROUND

The provision of healthcare generates waste which can be detrimental to health and environment. Staff who provide healthcare ought to be aware of the proper handling and the system of management of healthcare waste used by different hospitals.

MATERIALS AND METHODS

A survey of doctors, nurses and allied medical staff for their awareness of the hospital generation and handling of waste was conducted. A self-administered questionnaire was used.

RESULTS

Lack of awareness, ignorance of policy and procedure on the handling of healthcare waste and failure to attend educational activities were major defects found among healthcare staff in the study.

CONCLUSION

There is a need for a plan to improve the awareness of healthcare workers about hospital generated waste and its proper handling.
