Abstract
The global outbreak of the COVID-19 pandemic has given rise to a significant health emergency to adverse impact on environment, and human society. The COVID-19 post-pandemic not only affects human beings but also creates pollution crisis in environment. The post-pandemic situation has shown a drastic change in nature due to biomedical waste load and other components. The inadequate segregation of untreated healthcare wastes, chemical disinfectants, and single-use plastics leads to contamination of the water, air, and agricultural fields. These materials allow the growth of disease-causing agents and transmission. Particularly, the COVID-19 outbreak has posed a severe environmental and health concern in many developing countries for infectious waste. In 2030, plastic enhances a transboundary menace to natural ecological communities and public health. This review provides a complete overview of the COVID-19 pandemic on environmental pollution and its anthropogenic impacts to public health and natural ecosystem considering short- and long-term scenarios. The review thoroughly assesses the impacts on ecosystem in the terrestrial, marine, and atmospheric realms. The information from this evaluation can be utilized to assess the short-term and long-term solutions for minimizing any unfavorable effects. Especially, this topic focuses on the excessive use of plastics and their products, subsequently with the involvement of the scientific community, and policymakers will develop the proper management plan for the upcoming generation. This article also provides crucial research gap knowledge to boost national disaster preparedness in future perspectives.

Krishnamoorthy Y, Subbiah P, Rajaa S, Krishnan M, Kanth K, Samuel G, Sinha I. Barriers and Facilitators to Implementing the National Patient Safety Implementation Framework in Public Health Facilities in Tamil Nadu: A Qualitative Study. GLOBAL HEALTH, SCIENCE AND PRACTICE 2023; 11:e2200564. [PMID: 38135519 PMCID: PMC10749659 DOI: 10.9745/ghsp-d-22-00564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Accepted: 10/17/2023] [Indexed: 12/24/2023]
Abstract
BACKGROUND In 2017, the National Patient Safety Implementation Framework (NPSIF) was introduced in India to ensure patient safety at different levels of the health care delivery system by 2025. Evaluating the implementation status, feasibility, and challenges and obtaining suggestions for improvement are key to the successful and sustainable implementation of any national health framework. Hence, we explored the facilitators and challenges in implementing the NPSIF and sought suggestions to address the challenges. METHODS We adopted a descriptive qualitative approach to inquire about NPSIF implementation. Health care workers were selected using maximum variability sampling from 18 secondary- and tertiary-level public health care facilities in Tamil Nadu, India. From August to October 2021, we conducted a total of 80 key informant interviews and in-depth interviews with the relevant officers in-charge and HCWs of varied cadres. RESULTS Facilitating factors reported were facilities obtaining/working toward quality certification; availability of standard protocols and checklists; and government rewards for the best-performing hospitals, doctors, and staff. Major implementation challenges reported were staff shortages; lack of infrastructure, facilities, and equipment; lack of awareness about patient safety, noncompliance to standard guidelines, and lack of patient cooperation. Recommendations suggested to overcome these challenges included providing educational materials to patients, offering regular continuing medical education and training, improving record maintenance, having a dedicated staff/team and surveillance system setup for patient safety and dedicated staff for data entry, filling existing staff vacancies, and using a carryover option for funding. CONCLUSION Based on the current situation of patient safety practices in public health facilities in Tamil Nadu, it will be difficult to achieve full-scale implementation of the NPSIF by 2025. However, as a first step, a core patient safety committee can be formed at the state level to develop a Gantt chart for implementation based on the priorities over the next 2 years.

Abstract
The COVID-19 pandemic actualized questions about the proper management of biomedical waste while creating several regulatory challenges and requiring countries to look for an appropriate response. These issues have become particularly relevant for Kazakhstan, where waste management issues traditionally face inefficient legal regulation and are particularly acute. This study aims to answer the question of what regulatory problems Kazakhstan currently face in the area of proper biomedical waste management, and how existing foreign experience can help solve them. The present study highlights several pertinent challenges within the context of medical waste management. These include issues concerning the licencing activities associated with waste management, the absence of well-defined regional plans for the management of medical waste and the lack of effective strategies to address the proper handling and disposal of this specific category of waste. At the same time, there are reasons to say that the country requires additional technical and expert support in the field of medical waste management.

Abstract
Introduction segregation of biomedical waste (BMW) is the foremost and prime step for effective BMW management. This study was taken up to assess the BMW segregation compliance in patient care areas using a checklist-based scoring system to analyze the segregation compliance and establish feedback-based training programs. Methods this study was conducted between January 2020 to December 2021 at a government tertiary care hospital in Hyderabad. The compliance was calculated by giving a score of one for each day, such that if there was no noncompliance (NC) the score was 100% for a given location at the end of the month. A score of minus one was given for each day a noncompliance was noted and transfigured into percentages. A score of 100% was considered good, and below 95% was considered an action point necessitating root cause analysis and training. Results the BMW segregation compliance scores of the hospital for the year 2020 (96.5%) were compared with 2021 scores (97.5%). The outpatient department (OPD) and ICU had the poorest compliance rate of 93.7% and 93.6% respectively, compared to wards (96.2%). The most common factors influencing NC in BMW segregation were the joining of new staff, relocation, or new establishment of wards. The most common segregation error was found in the yellow disposal bags pertaining to the disposal of personal protective equipment. Conclusion this easy and simple scoring system was established to improve the segregation compliance of BMW. End of each month an area wise compliance is easily made such that areas with low scores could be trained.

Abstract
BACKGROUND Improper disposal of urban medical waste is likely to cause a series of neglective impacts. Therefore, we have to consider how to improve the efficiency of urban medical waste recycling and lowering carbon emissions when facing disposal. METHODS This paper considers the multi-cycle medical waste recycling vehicle routing problem with time windows for preventing and reducing the risk of medical waste transportation. First, a mixed-integer linear programming model is formulated to minimize the total cost consisting of the vehicle dispatch cost and the transportation costs. In addition, an improved neighborhood search algorithm is designed for handling large-sized problems. In the algorithm, the initial solution is constructed using the Clarke-Wright algorithm in the first stage, and the variable neighborhood search algorithm with a simulated annealing strategy is introduced for exploring a better solution in the second stage. RESULTS The computational results demonstrate the performance of the suggested algorithm. In addition, the total cost of recycling in the periodic strategy is lower than with the single-cycle strategy. CONCLUSIONS The proposed model and algorithm have the management improvement value of the studied medical waste recycling vehicle routing problem.

Abstract
Purpose The ongoing COVID-19 crisis has drastically changed the practice of biomedical waste (BMW) generation and management. Studies venturing into the facility level preparedness at various levels of healthcare delivery during pandemic situation is the need of the hour. Hence, we did this study to assess the BMW disposal practices amongst secondary and tertiary health facilities during COVID-19 pandemic in Tamil Nadu. Materials and methods This cross-sectional survey was conducted amongst doctors, nurses and allied healthcare staffs across various departments in 18 public health facilities across six districts of Tamil Nadu. Multivariable logistic regression analysis was done based on the random-intercept model to assess the determinants of BMW disposal practices. The effect size was reported as adjusted odds ratio (aOR) with 95% confidence interval (CI). Results In total, 2593 BMW disposal observations were made. During nearly three-fourth of the observations (73%), the BMW was disposed of appropriately. Nurses (aOR = 1.54; 95%CI: 1.06–2.23) and doctors (aOR = 1.60; 95%CI: 1.05–2.45), healthcare workers in Paediatrics department (aOR = 1.77; 95%CI: 1.13–2.76), healthcare workers in inpatient department (aOR = 2.77; 95%CI: 1.95–3.94) and injection outpatient department (aOR = 2.69; 95%CI: 1.59–4.47) had significantly better odds of having appropriate BMW disposal practices. Conclusion Our study shows that nearly during three-fourth of the observations, healthcare workers performed appropriate BMW disposal practices. However, measures should be taken to achieve 100% compliance by healthcare workers especially the target groups identified in our study by allocating appropriate resources and periodically monitor the BMW disposal practices.

Abstract
Biomedical wastes (BMWs) are potentially infectious to the environment and health. They are co-dependent and accumulative during the ongoing coronavirus disease-2019(COVID-19) pandemic. In India the standard treatment processes of BMWs are incineration, autoclaving, shredding, and deep burial; however, incineration and autoclaving are the leading techniques applied by many treatment providers. These conventional treatment methods have several drawbacks in terms of energy, cost, and emission. But the actual problem for the treatment providers is the huge and non-uniform flow of the BMWs during the pandemic. The existing treatment methods are lacking flexibility for the non-uniform flow. The Government of India has provisionally approved some new techniques like plasma pyrolysis, sharp/needle blaster, and PIWS-3000 technologies on a trial basis. But they are all found to be inadequate in the pandemic. Therefore, there is an absolute requirement to micromanage the BMWs based on certain parameters for the possible COVID-19 like pandemic in the future. Segregation is a major step of the BMW management. Its guideline may be shuffled as segregation at the entry points followed by collection instead of the existing system of the collection followed by segregation. Other steps like transportation, location of treatment facilities, upgradation of the existing treatment facilities, and new technologies can solve the challenges up to a certain extent. Technologies like microwave treatment, alkaline hydrolysis, steam sterilization, biological treatment, catalytic solar disinfection, and nanotechnology have a lot of scopes for the treatment of BMWs. Hi-tech approaches in handling and transportation are found to be fruitful in the initial steps of BMW management. End products of the treated BMWs can be potentially fabricated for the application in the built environment. Some policies need to be re-evaluated by the health care facilities or government administrations for efficient BMW management.

Abstract
The coronavirus (COVID-19) pandemic has created a global medical emergency. The unforeseen occurrence of a pandemic of this magnitude has resulted in overwhelming levels of medical waste and raises questions about management and disposal practices, and environmental impacts. The amount of medical waste generated from COVID-19 since the outbreak is estimated to be 2.6 million tons/day worldwide. In Australia, heaps of single-use gowns, facemasks/face shields, aprons, gloves, goggles, sanitizers, sharps, and syringes are disposed everyday as a result of the pandemic. Moreover, the establishment of new home/hotel quarantine facilities and isolation/quarantine centres in various Australian states and territories have increased the risks of transmission among people in these facilities and the likelihoods of general waste becoming contaminated with medical waste. This warrants the need to examine management and disposal practices implemented to reduce the transmission and spread of the virus. This study reviews the various management and disposal practices adopted in Australia for dealing with medical waste from the COVID-19 pandemic and their impacts on public health and the environment. To achieve the aims of this study, prior studies from 2019-2021 from various databases are collected and analysed. The study focuses on generation of medical waste from COVID-19, management and disposal methods, current problems/challenges and environmental and public health impacts. Considering the enormous risks involved and the significance of appropriate handling and disposal of medical waste from COVID-19, this study provides insights on short and long term responses towards managing COVID-19 waste in Australia. The study contributes to Australia's efforts against the transmission and spread of COVID-19 and provides recommendations for the development of workable and sustainable strategies for mitigating similar pandemics in the future.

Abstract
The importance of medical waste management has grown during the COVID-19 pandemic because of the increase in medical waste quantity and the significant dangers of these highly infected wastes for human health and the environment. This innovative review focuses on the possibility of materials, gas/liquid/solid fuels, thermal energy, and electric power production from medical waste fractions. Appropriate and promising treatment/disposal technologies, such as (i) acid hydrolysis, (ii) acid/enzymatic hydrolysis, (iii) anaerobic digestion, (vi) autoclaving, (v) enzymatic oxidation, (vi) hydrothermal carbonization/treatment, (vii) incineration/steam heat recovery system, (viii) pyrolysis/Rankine cycle, (ix) rotary kiln treatment, (x) microwave/steam sterilization, (xi) plasma gasification/melting, (xii) sulfonation, (xiii) batch reactor thermal cracking, and (xiv) torrefaction, were investigated. The medical waste generation data were collected according to numerous researchers from various countries, and divided into gross medical waste and hazardous medical waste. Moreover, the medical wastes were separated into categories and types according to the international literature and the medical waste fractions’ percentages were estimated. The capability of the examined medical waste treatment technologies to produce energy, fuels, and materials, and eliminate the medical waste management problem, was very promising with regard to the near future.
