Future impacts of antibiotic resistance

1. Future impacts of
antibiotic resistance

2. Why does this matter?
 Antibiotic resistance does not only influence health in
the global population at present, but has the potential
to cause devastating worldwide consequences in the
future
 Recognition of these possible future impacts helps to
emphasise the need for drastic change in the
prescription and usage of antibiotics

future-2015-6?r=US&IR=T

5. Post-antibiotic era
 It is estimated that if antibiotic resistance is not tackled,
10 million people could die per year of curable
diseases by 20501
 The economy could lose billions of dollars more per
year due to increased loss of public health goods as
well as the huge costs associated with dealing with this
issue
 The world may enter a post-antibiotic era, whereby
previously treatable infections and injuries can become
deadly once more2

7. Treatment failures
 Many drugs, after development, had negligible or very
low failure rates and generally succeeded in curing
various life-threatening diseases2
 With the emergence of antibiotic resistance, patients
worldwide have failed to respond to previously effective
antibiotic treatments2
 This includes the emergence of multidrug-resistant
tuberculosis, Plasmodium falciparum, methicillin-
resistant Staphylococcus aureus (MRSA) and so on3
 Drugs such as fluoroquinolones, carbapanems,
cephalosporins and so on are now ineffective in more
than half of people in countries all around the world2,3

8.  There has also been rapidly increasing resistance to drugs
used to treat tuberculosis, malaria, influenza, gonorrhea,
urinary tract infections and so on2
 With the rapid spread of antibiotic resistance, these
diseases will soon become extremely difficult to manage and
can cause increased disability and death2,3
 In terms of morbidity and mortality, diseases are expected to
vary across countries
 Malaria is expected to be the most significant in Asian
countries, while tuberculosis is expected to severely impact
Russia1

9. MRSA
 This is predicted to become a huge public health issue
 The scope of this resistance will extend to more settings –
hospitals used to be the only settings where MRSA was
found, but more community outbreaks can be expected4
 These outbreaks may happen in people who lack traditional
risk factors for MRSA4
 MRSA prevalence in the US community may reach 25% in
the next 10 years, with even higher rates within hospital
settings4

10. Loss of control over infection
 If antibiotic resistance continues, global health systems
will lose control over many infectious diseases
 The rates of hospitalisation and infection will be
elevated, and alternative treatments will need to be
sought
 Longer hospitalisation periods and greater extent of
disability3
 Death rates from infectious diseases will inevitably
increase

11. Resistance mechanisms
 There is the potential for new resistance mechanisms to
emerge, and for resistance rates as a whole to increase4
 Multiresistant streptococci, staphylococci and enterococci
will potentially cause substantial illness and be difficult to
combat, especially in parts of the world that have not yet
implemented strict control measures4
 Vancomycin-resistant antibiotics may become endemic on a
global scale4
 A huge number and range of antibiotics will be rendered
useless in the treatment of a large number of diseases

12. Development of antibiotics
 There have been no new antimicrobial classes developed for
gram-negative bacteria for decades4
 Vaccines have not been widely effective4
 Fluoroquinolones used to be widely effective against multiple
infections, but this is not the case anymore. There have also not
been any new class of antimicrobial agents to function as a
substitute for them4
 Several new antimicrobial drugs with different mechanisms of
action have failed in phase three trials4
 Antibiotics are being rendered useless very quickly but no novel
antibiotics have been found to be successful – this is very
concerning and can have devastating implications for the health of
global populations

13. Medical procedures
 Antibiotics have commonly been used to treat infections that
appear secondary to procedures such as caesarean child
birth, organ transplants, chemotherapy and so on1,2
 With the growing resistance against antibiotics, these
procedures will be able to cause diseases which may soon
be rendered incurable1
 Therefore, these procedures can become much more
dangerous, and are expected to cause higher rates of
persistent infection and death1
 This will impact not only wealthier countries where such
procedures are common, but also middle income countries
that are trying to implement health systems1

14. Costs of antibiotic resistance
 There will be a significant loss of public health goods due to
antibiotics being rendered useless by growing resistance, and
substantial economic losses
 Patients infected with drug-resistant bacteria generally suffer from
longer-lasting and more severe infections, and as such require
extended hospitalisation and increased treatment and care
resources 2,4,5
 Broad-spectrum antibiotics are being used increasingly for
empirical therapy of many common infections – these agents are
often costlier, and have more toxicity towards protective microflora.
They are also occasionally less effective5
 Alternative therapies and treatments are required, and these can
be expensive to develop or implement

15.  Therefore, it can be seen that antibiotic resistance is a
pressing issue that can have severe, negative
consequences on numerous countries worldwide.
 It is essential to understand these impacts in order to
grasp the importance of changing attitudes towards
antibiotic development, prescription and usage.
