How Antimicrobial Resistance Threatens Neonatal Mortality Rates Globally

Neonatal mortality remains a major health challenge across the world, which involves neonatal sepsis and other related factors of prematurity. Though many strides have been done in reducing NMR, there is a need for more appropriate interventions and strategies directed towards addressing the rise in the escalation of AMR. Combating AMR will be critical in improving neonatal survival rates while giving each newborn a healthier start into life globally.

The newborn period is the key period for infant health, and the first 28 days of life are critically important-both for survival and as a base to set lifetime health and development. Neonatal deaths globally have witnessed a significant decline over the past couple of decades. The neonatal mortality count has significantly reduced dropping from a high of 5 million in 1990 to as low as 2.3 million as of 2022. However, this decline notwithstanding, neonatal mortality is still staggeringly high across low-and middle-income nations.

Neonatal mortality rates are 22 per 1000 live births in India. Neonatal sepsis and prematurity are the main causes of neonatal deaths in these tragic events. Recognizing the gravity of the issue the Indian government started the Indian Newborn Action Plan (INAP) in 2014. The goal is to take NMR down to the single digits by 2030. This initiative has brought in several key interventions, including antenatal care (vaccines, micronutrient supplementation), skilled birth attendance, clean birth practices, and neonatal resuscitation techniques. More promisingly, postnatal interventions, including early initiation of breastfeeding and skin-to-skin contact, have been proven to work well in improving newborn survival rates.

Despite these improvements, one of the biggest concerns in neonatal care today is the growing problem of antimicrobial resistance (AMR) which seriously threatens efforts to reduce neonatal mortality.

What is Antimicrobial Resistance?

Antimicrobial resistance occurs when microorganisms such as bacteria, viruses and fungi evolve over time and become resistant to commonly used antibiotics and other medications. This resistance makes infections more difficult to treat, increasing the risk of mortality and complicating treatment options. The World Health Organization has classified AMR as one of the most urgent global health threats since it not only causes death and disability but also places immense pressure on healthcare systems, significantly raising the economic burden.

The sources of AMR are many, including poor hygiene and infection control in healthcare settings, overuse and misuse of antibiotics. Contributing factors to this rapidly growing problem are antibiotic prescriptions for patient needs that do not require them and failure to complete antibiotic courses, as prescribed.

AMR and Newborn Health

For neonates, the risk is much more vital for AMR. Neonates are particularly prone to developing infections due to their rather weak immune systems. Neonatal sepsis, severe bacterial infection, is one of the leading causes of neonate deaths and it often manifests complications when it is because of drug-resistant pathogens.

According to Dr. Apoorva Taduri, Consultant Neonatologist, "Neonatal sepsis accounts for a significant proportion of neonatal deaths, and AMR is making it worse. MDR pathogens cause around 30% of neonatal sepsis mortality globally.

Maternal health and care are also factors influencing AMR in neonates. Over-prescription of antibiotics during pregnancy increases the risk of neonatal sepsis and the development of multi-drug-resistant pathogens in newborns. This calls for prudent use of antibiotics during pregnancy and at the time of delivery. In fact, studies indicate that indiscriminate use of antibiotics in mothers has a direct impact on neonatal health, which may eventually lead to resistant infections in newborns.

One of the major issues is that the drug-resistant bacteria are causing an increasing number of healthcare-associated infections in the neonatal care settings, which include NICUs. Infections by such bacteria prove to be challenging to treat; they require more advanced, expensive interventions, and the period of risk of mortality and morbidity is extended.

Counteracting AMR in Neonatal Care

To combat AMR and reduce neonatal mortality a multifaceted approach is necessary. Dr. Taduri emphasizes the continuation of the strategies outlined by the Indian Newborn Action Plan (INAP), specifically in reducing neonatal sepsis and improving infection control. However, to combat AMR more must be done to ensure proper use of antibiotics in both maternal and neonatal care settings.

Key strategies for reducing AMR in neonatal care are:

1. Improving Infection Prevention Practice: This implies, therefore, that more efforts would be made regarding stricter hospital hygiene standards, strict equipment sterilization after its usage and even maintaining adequate hand hygiene. Enhanced infection control practices greatly impact minimizing AMR pathogens distribution.

2. Antibiotic Stewardship- Teaching the healthcare providers how not to use antibiotics is a crucial thing in preventing overuse prescription. Antibiotic stewardship programs are designed to promote use of antibiotics only when truly required; appropriate drug, dose and length of treatment should be taken.

3. Improved access to WASH: Access to clean water and sanitation is a fundamental aspect of preventing infections in mothers and newborns. WASH interventions such as clean birthing practices, can reduce the risk of neonatal sepsis due to unsanitary conditions.

4. Maternal Health Strengthening: Proper maternal care, such as proper vaccination, antenatal steroids, and supplementation of micronutrients, can reduce the risk of prematurity and neonatal infection. Prevention of infection in mothers is the first step towards prevention of infection in newborns.

5. Early Diagnosis and Treatment: Early identification and treatment of neonatal infections are very important. This includes proper screening for sepsis and the use of appropriate antibiotics based on the local resistance patterns. It also involves ensuring that infants receive adequate neonatal care, such as those provided in Special Newborn Care Units (SNCUs).

The rise of antimicrobial resistance is a global health challenge that requires urgent action. Combating AMR requires a coordinated effort from governments, healthcare systems and communities worldwide. In neonatal care, addressing AMR is essential to further reducing neonatal mortality rates and ensuring that every newborn has the opportunity to thrive.

As Dr. Taduri concludes, "While we have made substantial progress in reducing neonatal mortality, the emerging risk of antimicrobial resistance creates a major challenge for our efforts. Combating AMR requires a global collective effort, with priorities on infection prevention, responsible use of antibiotics, and enhancement of healthcare practices to ensure a healthier future for all newborns."
