RESUMEN

INTRODUCTION: Healthcare waste is any waste generated by healthcare facilities that is considered potentially hazardous to health. Solid healthcare waste is categorized into infectious and non-infectious wastes. Infectious waste is material suspected of containing pathogens and potentially causing disease. Non-infectious waste includes wastes that have not been in contact with infectious agents, hazardous chemicals, or radioactive substances, similar to household waste, i.e. plastic, papers and leftover foods. This study aimed to investigate solid healthcare waste management practices and develop guidelines to improve solid healthcare waste management practices in Ethiopia. The setting was all health facilities found in Hossaena town. METHOD: A mixed-method study design was used. For the qualitative phase of this study, eight FGDs were conducted from 4 government health facilities, one FGD from each private health facility (which is 37 in number), and forty-five FGDs were conducted. Four FGDs were executed with cleaners; another four were only health care providers because using homogeneous groups promotes discussion. The remaining 37 FGDs in private health facilities were mixed from health professionals and cleaners because of the number of workers in the private facilities. For the quantitative phase, all health facilities and health facility workers who have direct contact with healthcare waste management practice participated in this study. Both qualitative and quantitative study participants were taken from the health facilities found in Hossaena town. RESULT: Seventeen (3.1%) health facility workers have hand washing facilities. Three hundred ninety-two (72.6%) of the participants agree on the availability of one or more personal protective equipment (PPE) in the facility ''the reason for the absence of some of the PPEs, like boots and goggles, and the shortage of disposable gloves owes to cost inflation from time to time and sometimes absent from the market''. The observational finding shows that colour-coded waste bins are available in 23 (9.6%) rooms. 90% of the sharp containers were reusable, and 100% of the waste storage bins were plastic buckets that were easily cleanable. In 40 (97.56%) health facilities, infectious wastes were collected daily from the waste generation areas to the final disposal points. Two hundred seventy-one (50.2%) of the respondents were satisfied or agreed that satisfactory procedures are available in case of an accident. Only 220 (40.8%) respondents were vaccinated for the Hepatitis B virus. CONCLUSION: Hand washing facilities, personal protective equipment and preventive vaccinations are not readily available for health workers. Solid waste segregation practices are poor and showed that solid waste management practices (SWMP) are below the acceptable level.

RESUMEN

INTRODUCTION: Pharmaceuticals are used widely in radiography practice but pose an environmental risk. This study explored Australian radiographers' environmental attitude, pharmaceutical waste disposal practices, and knowledge and concern regarding the environmental impact of these pharmaceuticals. METHODS: This study utilised an anonymous, online questionnaire developed from two validated questionnaires. Participants (n = 150) held current registration with the Medical Radiation Practice Board of Australia and were working eight or more hours per week in a medical imaging practice (public or private). RESULTS: Participants did not answer all questions, hence percentages reported reflect the number of counts for each question. Most participants (71.4%; 105/147) disposed of contaminated pharmaceutical waste in clinical waste bins with 17.1% (15/146) disposing of it down drains. More hospital radiographers 13.54% (13/96) reported this disposal compared with 2.08% (1/48) of community-based radiographers (Fisher's Exact Test, p = 0.035). There was no difference in disposal of non-contaminated waste between practice settings - general waste bin (68.5%; 100/150), recycling bin (28.8%; 42/146), and clinical waste bin (41.8%; 61/146). Participants lacked knowledge of impacts on the food chain and the health of humans and wildlife. Only 34.7% (48/138) of participants expressed concern regarding the impacts of human excreted pharmaceuticals on the environment compared with 65.8% (98/149) regarding impacts from incorrect disposal. Many (18.4%; 25/136) reported having received no information on correct disposal of pharmaceutical waste. CONCLUSION: This study highlighted participants' lack of knowledge on how pharmaceuticals enter the natural environment and the subsequent impacts on the environment and on the health of humans, and flora and fauna. They lacked knowledge of correct pharmaceutical waste disposal methods, but most agreed it was their professional responsibility to dispose of waste correctly. IMPLICATIONS FOR PRACTICE: Improving radiographers' pharmaceutical waste disposal practices through education and professional support will reduce environmental impacts and also provide financial co-benefits if non-contaminated waste is recycled where possible and not incinerated.

RESUMEN

Healthcare waste management is a critical aspect of public health and environmental protection, particularly in establishments such as dental clinics. This study examined the dental clinic waste (DCW) management processes in clinics within the city of Belo Horizonte, Brazil. Utilizing data from Healthcare Waste Management Plans (HCWMP) provided by the Urban Cleaning Superintendence, the study investigated waste generation, segregation, storage, collection, treatment, and final disposal practices. The results revealed that hazardous DCW represented a significant portion (26.5 %) of waste generated in dental clinics, exceeding the World Health Organization's recommended threshold. Biological waste (22.9 %), mainly consisting of cotton, gauze, and gloves contaminated with blood or body fluids, was the most generated hazardous waste group, followed by chemical (2.2 %) and sharps waste (1.3 %). Incineration was the predominant treatment method for hazardous DCW, raising concerns about environmental impacts and greenhouse gas emissions. Non-hazardous waste, primarily destined for landfills, had limited recycling rates (2.4 %), emphasizing the need for improved waste management strategies to minimize environmental impacts and increase circular economy. Challenges in DCW management included inadequate segregation practices, limited recycling initiatives, and incomplete HCWMPs lacking descriptions of waste management beyond establishment boundaries. Addressing these challenges requires comprehensive training programs, strengthened regulations, and increased environmental awareness among healthcare professionals. In conclusion, improving DCW management in dental clinics is crucial for mitigating occupational and environmental risks. Collective efforts are needed to enhance waste segregation, promote recycling, and ensure compliance with regulations, ultimately safeguarding public health and the environment.

RESUMEN

The proper disposal of pharmaceuticals has become a prime concern in contemporary healthcare and environmental management. The evolving awareness highlights the ecological and public health risks associated with pharmaceutical waste. Therefore, evaluating medication disposal patterns and public awareness regarding pharmaceutical-related environmental issues is crucial for promoting responsible practices. The primary aim of this study is to identify the determinants of participation in the Medicine Return Program (MRP) among Malaysians. This cross-sectional study employed snowball sampling and an online questionnaire, disseminated via multiple social media platforms. Results: Out of 389 respondents, 46% were 18 to 29 years old, 61% were female, and 69.7% attained a tertiary educational level. Most of them (71.5%) reported disposing of their unused medicines into the rubbish bin, indicating that this disposal method is prevalent among Malaysians. Only 26.2% participated in the MRP program. The study revealed that 73.0% of respondents were aware of pharmaceutical-related environmental contamination. Furthermore, significant associations were demonstrated between a factor of receiving advice from healthcare professionals (p < 0.001), awareness level on environmental pharmaceutical contamination (p < 0.001) and MRP (p < 0.001) and willingness to participate in MRP (p < 0.001) with MRP support. This study provides valuable insights on Malaysian pharmaceutical disposal practices and the factors influencing MRP participation. These findings can inform targeted interventions and public health campaigns to improve medication disposal behaviors and reduce pharmaceutical waste's environmental impact.

RESUMEN

BACKGROUND: Inefficient supply chain management within the US healthcare industry results in significant financial and environmental impact. Unopened medical supplies may routinely be discarded in the Emergency Department (ED), contributing as a source of unnecessary medical waste. OBJECTIVES: Quantify the financial and environmental impact of unopened medical supplies that are routinely discarded in two EDs. METHODS: The study utilized a waste audit of collection bins targeting unopened medical supplies that would have otherwise been discarded. Associated financial cost was calculated using data from the purchasing department and from an online search. End-of-life (EOL) environmental impact was calculated using the M+ Wastecare calculator. A lifecycle analysis was performed on a supplier-packaged intubation kit, which the study identified as a significant source of waste. RESULTS: High volumes of unused, unopened supplies (143.48 kg) were collected during the study period with a yearly extrapolated value of 1337 kg. Purchasing costs over 44 days at Hospital A and 37 days at Hospital B for these items amounted to $16,159.71 across both sites with a yearly extrapolated value of $150,631.73. Yearly extrapolated EOL impact yielded 5.79 tons per year of CO2eq. Components from supplier-packaged intubation kits were found to contribute to 45.2% of collected items at one site which purchased them. Lifecycle analysis of an intubation kit yields 23.6 kg of CO2eq. CONCLUSION: This study demonstrates that the disposal of unopened medical supplies contributes a significant source of financial and environmental waste in the ED setting. The results continue to support the trend of procedure kits generating significant environmental and financial waste.

RESUMEN

The Australian health care system contributes 7% of the national greenhouse gas emission footprint and generates massive waste streams annually. Operating rooms are a particular hotspot, generating at least 20% of the total hospital waste. A systematic search of several global academic databases was conducted in mid-2022 (articles from 1992 to 2022) for peer-reviewed research relevant to waste management in the operating rooms. We then used thematic analysis to enumerate and characterise the strategies and barriers to sustainable waste management in the operating room. The waste reduction strategies focused on avoidance of high carbon products; correct waste segregation and reduced overage; reusing, reprocessing, and repurposing devices; and improved recycling. The first barrier identified was a constrained interpretation of the concept of "first do not harm", ingrained in surgeons' practices, in prioritising single-use surgical products. The second barrier was ineffective or insufficient waste education. The third barrier was the immediate cost of implementing waste management compared with the long term realisation of environmental and economic benefits. The last barrier to implementing institutional practice change was the lack of policies and regulations at the local hospital, federal and international levels. We also evaluated the knowledge gaps in current surgical waste research, including lack of benchmarking data and standardised regulations concerning reusable or reprocessed devices, as well as the methods used to promote pro-sustainability behavioural change.

RESUMEN

Medical waste incineration fly ash (MWI FA) is classified as a hazardous solid waste. Therefore, the development of recycling technologies to convert MWI FA into useful products is necessary and challenging. In this study, we developed a sustainable approach for preparing a catalyst through the pyrolysis of water-washed MWI FA (WW FA-x, where x corresponds to the pyrolysis temperature). Subsequently, it was applied as a potent peroxydisulfate (PDS) activator to remove tetracycline (TC) from water. The results showed that the WW FA-800 exhibited remarkable adsorption performance as well as highly efficient catalytic activation of PDS, with a 115 mg/g maximum TC adsorption capacity and 93.5% (reaction kinetic rate = 315 µmol/g/h) TC removal within 60 min. A synergistic effect was achieved by adsorption and PDS activation. TC degradation was primarily driven by non-radical (1O2 and electron transfer) processes. WW FA-800 possesses multiple active sites, including defects, π-π*, O-CO groups, Fe0, and Cu(I). Three possible pathways for TC decomposition have been proposed, with the majority of intermediates exhibiting less toxicity than TC. Furthermore, the WW FA/PDS system exhibited an excellent anti-interference ability, and universality in the degradation of various organic contaminants. Notably, energy consumption was minimal, approximately 2.80 kWh/(g·TC), and the leachability of heavy metals in the WW FA-800 was within acceptable limits. This study provides a MWI FA recycling route for the development of highly active catalysts.

RESUMEN

PURPOSE OF THE REVIEW: Wastewater is a term used to describe water that has undergone degradation in quality owing to anthropogenic activities or natural processes. Wastewater encompasses liquid waste originating from academic institutions, households, agricultural sector, industries, mines and hospitals. Hospital wastewater contains potentially hazardous substances including residues of pharmaceuticals, radioisotopes, detergents and pathogens, with detrimental impacts to the environment and human health. Nevertheless, studies related to hospital waste management are limited in Africa, particularly in Southern Africa. This research offers an overview of aspects surrounding hospital wastewater in Southern Africa, focusing on Zimbabwe. Already published and grey literature was reviewed to compile the paper. RECENT FINDINGS: Number of patients, nature of medical services offered and hospital size influences generation of hospital wastewater. Partially and non-treated hospital wastewater is managed together with municipal wastewater. Management of hospital wastewater is impeded by shortage of resources, lack of co-ordination among responsible authorities and ineffective legal framework enforcement, among other challenges. Inappropriate hospital wastewater management results in environmental contamination, causing human ailments. Attainment of sustainable hospital wastewater management requires clearly defined and enforced legislation, collaboration of accountable stakeholders, sufficient resources and enhanced awareness of involved stakeholders. Application of technologies that uphold recycling and reuse of wastewater is essential to reach Sustainable Development Goals, Zimbabwe Vision 2030 and National Development Strategy 1 targets, particularly those dealing with environmental protection while upholding human health.

RESUMEN

BACKGROUND: The proper management of isolation waste is of utmost importance in healthcare facilities to prevent the spread of infections and protect both healthcare workers and the general public. This study investigated waste handlers' knowledge of the management of isolation waste at Dr. George Mukhari Academic Hospital in Gauteng, South Africa. METHODS: A survey was conducted to assess waste handlers' understanding of waste types, colour codes, safety precautions, and awareness of internal policies related to isolation waste management. RESULTS: The study found that the majority of waste handlers demonstrated a good understanding of waste types generated in the isolation unit, including sharps waste, human tissue waste, infectious waste, and general waste. They also correctly identified examples of sharp waste, such as injections, blades, glass slides, and needles. Additionally, most respondents were aware of the colour code used for representing infectious waste as "yellow" and "red." The study revealed a statistically significant association between waste handlers' age and their knowledge of isolation waste, suggesting that age may influence their understanding of waste management practices. Furthermore, experience was found to be significantly associated with waste handlers' knowledge of the health-hazardous nature of isolation waste. While the majority of waste handlers recognized the importance of wearing protective clothing and correctly marking isolation waste, some respondents were not aware of the internal policy for waste handling such as guidelines and protocols specific to the segregation, packaging, labeling, and disposal of waste generated within the isolation units. CONCLUSION AND CONTRIBUTION: These findings highlight the importance of continuous training, targeted education, and policy dissemination to ensure effective waste management and adherence to safety protocols among waste handlers.

RESUMEN

PURPOSE OF REVIEW: Climate change has immediate impacts on women's health. Hospitals and operating rooms are large contributors to greenhouse gas (GHG) emissions and waste. This article will review current green initiatives designed to minimize environmental impact in the operating room and highlight areas for future improvement. RECENT FINDINGS: From a materials perspective, reusable goods result in less GHG emissions while being just as efficacious, well tolerated, and easy to use. Materials should be opened judiciously, only as necessary. Processing regulated medical waste produces greater GHG emissions, so waste should be properly sorted, and items which are not biohazard waste should be processed separately. Choosing appropriate anesthesia and utilizing an 'off' setting, in which operating rooms are shut down when not in use, can also drastically decrease the environmental impact of surgery. Further research is needed to determine effective implementation in hospitals. SUMMARY: This article summarizes current attempts to make operating rooms more sustainable. Many practices result in a decreased carbon footprint and cost savings without adversely affecting patient outcomes. Gynecologic surgeons and the hospitals in which they practice need to focus on implementing these changes in a timely fashion.

RESUMEN

Medical waste incineration ash (MWIA) has significant concentrations of heavy metals, dioxins, and chlorine that, if handled incorrectly, might cause permanent damage to the environment and humans. The low content of calcium (Ca), silicon (Si), and aluminum (Al) is a brand-new challenge for the melting technique of MWIA. This work added coal fly ash (CFA) to explore the effect of melting on the detoxication treatment of MWIA. It was found that the produced vitrification product has a high vitreous content (98.61%) and a low potential ecological risk, with an initial ash solidification rate of 67.38%. By quantitatively assessing the morphological distribution features of heavy metals in ashes before melting and molten products, the stabilization and solidification rules of heavy metals during the melting process were investigated. This work ascertained the feasibility of co-vitrification of MWIA and CFA. In addition, the high-temperature melting and vitrification accelerated the detoxification of MWIA and the solidification of heavy metals.

RESUMEN

Plasma gasification melting (PGM) provides reliable disposal of toxic medical waste with a low heating value, which is capable of converting waste into energy. This study investigates the performance of experiments on plasma gasification for the treatment of chemical-pharmaceutical medical waste (CPMW) with an air medium. A comparative analysis is performed for gasification characteristics at three reactor temperatures (1000, 1400, and 1800 °C). Moreover, a thermodynamic equilibrium model is developed to assess performance features such as syngas yield, high heating value, and cold gas efficiency in the gasification temperature range of 1000-1800 °C. A comparison of the experiment and computational outcomes shows a good agreement. The results show that the quality of syngas and heating value is improved by increasing the temperature of the plasma gasifier so that at 1800 °C, H2, CO, and higher heating value (HHV) are obtained as 41 %, 37 %, and 10 MJ/Nm3, respectively. The obtained syngas is a clean fuel with low sulfur-containing and nitrogen-containing. The experimental results provide an extensive comprehension of CPMW gasification in a plasma reactor and consider a possibility for hydrogen and energy production.

RESUMEN

Globally, COVID-19 has not only caused tremendous negative health, social and economic impacts, but it has also led to environmental issues such as a massive increase in biomedical waste. The biomedical waste (BMW) was generated from centralized (hospitals, clinics, and research facilities) and extended (quarantine camps, COVID-19 test camps, and quarantined homes) healthcare facilities. Many effects, such as the possibility of infection spread, unlawful dumping/disposal, and an increase in toxic emissions by common BMW treatment facilities, are conjectured because of the rise in waste generation. However, it is also an opportunity to critically analyze the current BMW treatment scenario and implement changes to make the system more economical and environmentally sustainable. In this review, the waste disposal guidelines of the BMW management infrastructure are critically analyzed for many functional parameters to bring out possible applications and limitations of individual interventions. In addition, an investigation was made to select appropriate technology based on the environmental setting.

RESUMEN

PURPOSE OF REVIEW: The healthcare sector has a substantial environmental footprint, and the delivery of anesthesia contributes significantly. Inhaled anesthetics themselves are potent greenhouse gases, unused intravenous medication exert toxic effects on the environment, and the increasing reliance on single-use devices has led to an ever-growing amount of solid waste produced in operating rooms. This review discusses many of these environmental impacts and suggests practices to mitigate the environmental footprint of anesthetic practice. RECENT FINDINGS: The choice of anesthesia maintenance has significant environmental implications, with nitrous oxide and desflurane having the highest carbon footprint of all anesthetic agents. Using low fresh gas flows and supplementing or replacing inhalational agents with propofol leads to a significant reduction in emissions. Many intravenous anesthetic agents pose a risk of environmental toxicity, and efforts should be made to decrease medication waste and ensure appropriate disposal of unused medications to minimize their environmental impacts. Additionally, consideration should be given to replacing single-use devices in the operating rooms with reusable alternatives that are often both environmentally and economically superior. And solid waste generated in the operating room should be segregated thoughtfully, as processing regulated medical waste is a highly energy-intensive process. SUMMARY: Significant opportunities exist to improve the environmental footprint of anesthesia practice, and with the rapidly worsening climate crisis, the importance of implementing changes is greater than ever.

RESUMEN

BACKGROUND: The rapid development of medical care innovations and the use of newer technologies have resulted in a significant rise in the quantity of waste produced per patient within health care facilities. Biomedical waste in particular has emerged as a pressing concern due to its inherent propensity to pose health hazards and cause environmental harm. The World Health Organization has identified a lack of knowledge and training as primary factors contributing to the failure of Biomedical waste management (BMWM). Thus, our study sought to examine the relationship between BMWM level of knowledge and prior training among health care professionals (HCPs) in 4 different regions in Saudi Arabia. METHODS: Our study used a cross-sectional design to investigate the BMWM level of knowledge and prior training among HCPs in 4 different regions in Saudi Arabia. Multiple linear and logistic regression was used to assess if Biomedical waste management (MBWM) knowledge and prior tanning are significantly associated with the demographics and professional characteristics of HCPs. RESULTS: 501 HCPs participated in the study. More than half were male, the majority fell within the age range of 24 to 36 years and held a bachelor's degree. The level of BMWM knowledge among HCPs was moderate (M = 31.14, SD = 4.89) and positively associated with HCPs' prior training in BMWM, workplace environment, and overall experience in the field. Only 26% of the HCPs had received prior BMWM training, and it varied considerably by sex, geographic location, and professional experience. CONCLUSIONS: Our study demonstrates a moderate knowledge and lack of training in BMWM among HCPs in Saudi Arabia. Thus, we recommend a national strategy for incorporating infection prevention and control methods associated with BMWM into all health care programs. Furthermore, it is imperative for health officials to enact prompt and efficient surveillance measures, as well as conduct frequent training sessions for HCPs and support personnel.

RESUMEN

BACKGROUND: Medical Waste (MW), conceptualized as waste generated in the diagnosis, treatment, or immunization of human beings or animals, posing massive threat to public health. Environment-friendly public attitudes promotes the shaping of pro-environmental behavior. However, the public attitudes of MW and the potential determinants remained scarce. The present study aims to reveal globally public attitudes towards MW and captured the determinants. METHODS: We integrated the crawler technology with sentiment analysis to captured the public attitudes toward MW across 141 specific countries from 3,789,764 related tweets. Multiple cross-national databases were integrated to assess characteristics including risk, resistance, environment, and development. The spatial regression model was taken to counterbalence the potential statistical bias. RESULTS: Overall, the global public attitudes towards MW were positive, and varied significantly across countries. Resilience (ß = 0.78, SD = 0.14, P < 0.01) and development (ß = 1.66, SD = 0.13, P < 0.01) posed positive influence on public attitudes towards MW, meanwhile, risk (ß = -0.1, SD = 0.12, P > 0.05) and environment (ß = 0.09, SD = 0.09, P > 0.05) were irrelated to the shaping of positive MW public attitudes. Several positive moderating influences was also captured. Additionally, the cross-national disparities of the determiants were also captured, more specific, public attitudes towards MW in extremely poor areas were more likely to be negatively affected by risks, resilience and development. CONCLUSIONS: This study focused mainly on the public attitudes as well as captured the potential determinants. Public attitudes towards MW were generally positive, but there were large cross-national disparities. Stakeholders would need to designate targeted strategies to enhance public satisfaction with MW management.

RESUMEN

Background: The take-back campaign, which focuses on enhancing public awareness, safe medication disposal practices, stakeholder engagement and patient participation was used to promote medication safety in Kuwait. Aim: To evaluate the effectiveness of the take-back campaign in promoting medication safety in Kuwait. Methods: The campaign was implemented systematically through several stages of planning, communication and coordination among several stakeholders. This social media campaign encouraged individuals from the participating healthy cities to bring unwanted medications to designated collection centres. Returned medications were categorized based on the British National Formulary and data analysis was conducted using Excel. Consultations were held at the collection sites to increase patient confidence in medication compliance and safety. The medications were sorted and disposed safely. Results: The take-back campaign lasted 56 hours over a period of one month. It successfully engaged 405 households and collected 1005 kg of medication, comprising 7648 items, over a period 6 working days. Fifty-seven percent of the medications collected through the campaign originated from the Ministry of Health and 43% from the private sector. Fifty-two percent had expired and 59% were in solid dosage form. Painkillers comprised the largest group (18%) among the returned medications. Conclusion: The take-back campaign effectively raised awareness about medication safety and provided a safe disposal mechanism for unused and expired medications. This campaign has provided a foundation for future initiatives and contributed significantly to improving medication safety and public health outcomes in Kuwait.

RESUMEN

PURPOSE OF REVIEW: This review aims to provide an update on the results of studies published in the last two years involving the development of sustainable practices in hospital and operating theaters (OT). RECENT FINDINGS: Recently, many studies evaluated various initiatives to better understand the environmental impact of the OT but also to minimize its environmental impact. Many trials evidenced the positive impact of the instrument's reuse using an appropriate reprocessing procedure. Better waste segregation is associated with a reduction of produced waste and contributes to a significant reduction in CO 2 equivalent emissions. Regarding anaesthetic gas, Desflurane is known to have the worst environmental impact and the majority of the study evidenced that its reduction permits to drastically reduce greenhouse gas emission of the OT. SUMMARY: Greening the OT necessitates climate-smart actions such as waste reduction, the improvement of reusable instruments, recycling of our waste and better anaesthetic gas management. Within the last two years, many efforts have been made to reduce and better segregate waste produced in the OT and also to better understand the environmental impact of disposable and reusable devices.
