Millions of people now survive what were previously life-threatening infections. But antibiotics are finite resources and misuse has led to antibiotic resistance and reduced efficacy within just a few years of introduction of each new antibiotic. The ultimate aim is to identify know-do gaps and strategies to prevent ABR, antibiotic resistance reversal research papers.
Methods: The review covers four main data bases, Web of Science, Medline, Scopus and Ebsco searched for — Of these, were unique titles. After screening of the titles for relevance, abstracts were read, and of these papers were read in full.
An additional 53 references were identified from these papers, and 64 published during and were also included. The final scoping review database thus consisted of papers. Results: A thematic structure emerged when categorizing articles in different subject areas, serving as a proxy for interest expressed from the research community. The research area has been an evolving one with about half of the papers published during the past four years of the study period.
Epidemiological modelling needs strengthening and there is a need for more and better surveillance systems, especially in lower- and middle-income countries. There is a wealth of information on the local and antibiotic resistance reversal research papers uses and misuses of antibiotics.
Educational and stewardship programmes basically lack evidence. Several studies address knowledge of the public and prescribers. The lessons for policy are conveyed in many alarming reports from national and international organizations. Conclusions: Descriptive rather than theoretical ambitions have characterized the literature. If we want to better understand and explain the antibiotic situation from a behavioural perspective, the required approaches are lacking.
A framework for an epidemiological causal web behind ABR is suggested and may serve to identify entry points for potential interventions. Antibiotics have become the cornerstone for the treatment of infectious diseases and contributed significantly to the dramatic global health development during the last 70 years.
But antibiotics are finite resources. Misuse has led to antibiotic resistance ABR and reduced efficacy within just a few years of introduction of each new antibiotic [ 1 ]. The problem was foreseen by Alexander Fleming in his Nobel speech in when he concluded that ´ the time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant´.
But, as late as inthe US Surgeon General William H Stewart stated that ´ it is time to close the book on infectious diseases and declare the war against pestilence won´ [ 2 ]. The development of ABR is a direct response to the misuse of antibiotics in healthcare, the animal industry, agriculture and aquaculture.
Misuse refers to use without need, use without prescription, self-medication, irregular or interrupted dosing or sharing of antibiotic. Combating ABR by detecting, preventing, and controlling resistance requires strategic, coordinated, and sustained efforts.
This antibiotic resistance reversal research papers for national and international engagement of governments, academia, industry, healthcare providers and the general public. This will not only support patient care but also foster economic growth and national security [ 3 ].
Antimicrobial resistance AMR is a broader term, encompassing resistance to drugs to treat infections caused by bacteria and other microbes such as parasites e. malariaviruses e. HIV and fungi antibiotic resistance reversal research papers. Incentives for the pharmaceutical industry to develop new drugs are counteracted by our ambition to limit antibiotic use and industry priorities are therefore often directed towards investment in medicines to treat chronic diseases that require long-term consumption, antibiotic resistance reversal research papers.
Behind the development of resistance are also knowledge gaps, antibiotic resistance reversal research papers, preconceived notions, lack of adherence in patients to prescribing and in prescribers to guidelines.
We need to raise awareness about ABR, change behaviours, antibiotic resistance reversal research papers, develop context-specific guidelines for prescribers, and introduce regulations for use in all areas. Industry needs to work with policy-makers and embrace new business models to prevent the spread of antibiotic-resistant infections [ 9 ].
Every year,people die from resistant infections. In their final report, antibiotic resistance reversal research papers, the Wellcome Trust and the British Government estimated that, at the current rate of increase, 10 million people will die during the year as a result of AMR [ 10 ]. Ten million deaths in would exceed the 8. The World Bank estimates that the economic impact may be greater than from the —09 global financial crisis, cutting between 1.
The true cost of not being able to use antibiotics routinely is difficult to calculate [ 13 ]. Cost estimates have been crude, being current rather than future and applying to developed, rather than developing countries [ 14 ]. Antibiotic resistance can affect people of all ages in all countries. It is estimated that 5. Many lives could have been saved if antibiotics had worked and been available. This number is far more than theannual deaths worldwide that are due to ABR.
Preserving antibiotic effectiveness while ensuring universal access, is thus an ethical obligation [ 15 ]. Antibiotics are a common global utility with limited sustainability which has been overlooked in the implementation of the Sustainable Development Goals SDGs and should be acknowledged along with other fundamental global concerns, such as climate change.
This may help us to understand the consequences of not taking action [ 16 ]. It is not a systematic review of research questions and does not follow the standard format for such.
The ultimate aim is to identify know-do gaps in research and strategies to prevent ABR. Although the literature often addresses the broader field of antimicrobial resistance, this report, in general, deals with antibiotic resistance. Duringa structured search in the published literature —17 was conducted across four main data bases, Web of Science, Medline, Scopus and Ebsco. These are not unique hits since there are overlaps between the data bases, especially between Web of Science and Medline.
Matching for each of the data bases to the narrowing of the search criteria resulted in papers remaining of the initial , i. Flow chart for the selection of papers on the prevention of antibiotic or antimicrobial resistance resulting in unique references. After screening of the titles of these references for relevance, abstracts were read and screened for relevance and of these papers were included and read in full.
An additional 53 references were identified from these papers, and 64 published during or were also included. The research area has been an evolving one with half of the papers published during the past four years of the study period. A large proportion of papers addressed how ABR can be counteracted within health facilities through better compliance with treatment guidelines and also through national and global strategies. Epidemiological surveillance methods provide valid tools for this.
The historical background referring to the relatively short periods during which antibiotics have been used and resistance has evolved, has sometimes been used as the basis for a number of scenarios modelling the impact of no action.
The ABR field is increasingly recognized as a national and international policy issue. Alternatives to antibiotics are on the agenda, mostly through pre- and probiotics. Guidelines and strategies are often implemented as stewardship or educational programmes, antibiotic resistance reversal research papers, while others address knowledge or awareness among the public or the prescribers.
Antibiotic resistance reversal research papers the importance of preventing infections in the first place, it is noted that, proportionately, few papers are dealing with mechanisms or how to enhance the immune system. While reading the papers, each paper was classified by the author reflecting its main scope. A thematic structure of possibly overlapping subject areas thus gradually emerged. Figure 3 may thus serve as a proxy for interest expressed from the research community relating to prevention potentials during the antibiotic resistance reversal research papers 20 years.
Figure 4 provides an initial framework for an epidemiological causal web behind ABR and which will be pursued antibiotic resistance reversal research papers the assessment of the literature following the themes in Figure 3.
Socio-cultural and individual determinants along with biological characteristics are driving ABR occurrence and variation. These background factors are influenced by the levels and types of action from communities and administrative bodies. In parallel, knowledge development is on-going generated by official sources, bio-medicine and health care with input from research.
The consequences in terms of individual and population health are all dependent on ABR development modified by the outcome of new knowledge and the impact of prevention, infection control and resistance mitigation. Epidemiological data provide knowledge about the distribution of factors that determine health and disease in populations. Data on the epidemiology of ABR and infectious diseases are essential to inform our understanding of the patterns of use and misuse of antibiotics and their consequences [ 17 ].
Diarrhoeal diseases impose a substantial burden on LMICs, being the second most common cause of death amongst children, and claiming 1. Sixty percent of these deaths are associated antibiotic resistance reversal research papers inadequate access to safe water and sanitation. It is estimated that improved sanitation infrastructure in India will result in million fewer diarrhoea cases being treated with antibiotics by [ 18 ].
Even though seventy percent of diarrhoeal episodes are viral rather than bacterial, antibiotics are often first-line treatment. Modelling suggests that across four middle-income countries India, Indonesia, Nigeria and Brazil close to million courses of antibiotics are used to treat both bacterial and viral diarrhoea each year. It is estimated that diarrhoeal disease in these countries would be reduced by some 60 percent with universal access to improved water and sanitation [ 10 ]. Nevertheless inappropriate drug use for diarrhoeal disease is a major cause of increasing ABR [ 19 ], antibiotic resistance reversal research papers.
The global divide is illustrated in many contrasting international scenarios. While many children in high-income countries HICs are prescribed antibiotics for common upper respiratory infections, death tolls are high in LMICs because antibiotics do not work. In India, 58, infants died in from resistant bacterial infections [ 20 ]. The epidemiology of ABR also includes factors beyond individual control and that require interventions at national levels.
These factors vary by regions and global action requires combined international efforts [ 23 ]. A study among 27 European countries concluded that a nation´s educational level and governance system impacted on antibiotic use with higher consumption in more poorly managed countries in which national educational standards were lower [ 24 ]. Specifically, countries with high levels of corruption had higher antibiotic consumption rates, suggesting that ABR is not solely a medical, but also a behavioural and a social problem.
These findings were corroborated in a multivariate analysis of data from the European Quality of Government Index, in which corruption accounted for a significant amount of the between-region variation in antibiotic consumption. Even after controlling for socio-economic development, dysfunctional public institutions in the health sector were responsible for much of the inappropriate antibiotic consumption [ 25 ].
In a global assessment for countries, after accounting for type of governance, education, economy, health care spending and community infrastructure, it was concluded that reducing antibiotic consumption alone would not control resistance. Independent of antibiotic resistance reversal research papers consumption, antibiotic resistance reversal research papers, poor infrastructure e. sanitationpoor governance e.
corruption and low health expenditure were all associated with higher rates of resistance [ 26 ].
