Evidence-based medicine is recognised as being important. Clinical trials and subsequent systematic reviews of clinical trials are the key determinants of efficacy of an intervention. Medicines have made a major contribution to the health of children. Antibiotics are essential for the treatment of sepsis and are life-saving medicines. Similarly, antiasthmatic drugs and antiepileptic drugs can be both life-saving and also significantly enhance the quality of life, reducing morbidity from asthma and epilepsy, respectively.

Inappropriate use of medicines, however, may result in problems such as increased resistance to antibiotics or side effects.1 The rational use of medicines has been recognised as important for the health and well-being of all by the WHO for a long time. Irrational prescribing remains a problem in paediatric patients of all ages. Studies of drug utilisation in neonates have highlighted inappropriate use of new broad spectrum antibiotics and polypharmacy as major problems in neonates.2 3

There have been more studies of irrational prescribing in children than in neonates. Overuse of antibiotics in children has been reported in both high-income4 and low-income countries.5 Other examples of inappropriate use of medicines are the widespread use of cough medicines in children6 and polypharmacy.7 Polypharmacy is associated with an increased risk of drug toxicity. A systematic review of the toxicity of levetiracetam found that polypharmacy was associated with both a greater risk of drug toxicity (64% children compared with 22% children on monotherapy) and discontinuation due to toxicity (4.5% vs 0.9% on monotherapy).8 There is a risk of toxicity with every medicine and therefore medicines should only be used if they are clinically indicated.9

There has been a notable increase in the use of psychotropic medicines in children in many countries. A Norwegian study documented increased use of stimulants and hypnotic/sedative agents over a decade.10 The differences in guidelines and licensing for antipsychotics in children and adolescents between different countries demonstrate the lack of a clear evidence base to allow rational prescribing.11

In order to facilitate rational prescribing, the WHO has produced numerous guidelines. For example, the WHO guideline on child pneumonia recommends amoxicillin as first-line treatment.12 Alongside the guidelines, the WHO produced their seventh Essential Medicines for Children list (EMLc) in 2019.13 The EMLc gives specific guidance re-choice of antibiotic in different clinical situations. The antibiotics included in the EMLc are divided into three groups.13 The first group (access) have activity against a wide range of commonly encountered pathogens. They also have lower resistance potential than other antibiotics. They are recommended as essential first or second choice empirical antibiotics. The second group (watch) have higher resistance potential and are recommended for a limited number of specific infections. Their use needs to be monitored as key targets of stewardship programmes. The third group (reserve) should be reserved for treatment of confirmed or suspected infections due to multidrug-resistant organisms. Their use needs to be monitored in national and international stewardship programmes. It is to be hoped that this division of the essential antibiotics will minimise irrational use.

Stewardship programmes have been shown to be of benefit in neonates14 and children.15 Quality indicators are useful in evaluating antibiotic use and 10 quality indicators have been proposed for use in hospitalised neonates and paediatric patients.16 Others have proposed 25 quality indicators to evaluate treatment of community acquired pneumonia.17 Two simple quality indicators have been used for community infections. One is the proportion of children receiving amoxicillin as the first antibiotic (target 50%) and the other was the proportion of children who received cephalosporins or macrolides (maximum 10%).18 Both relate to community infections.

It is important to recognise that it is access to healthcare and antibiotics rather than choice of antibiotic, that is the main reason for the higher mortality of infections in low-income and middle-income countries. The production of the EMLc enables researchers to study the availability of the essential medicines. Unfortunately, studies usually show limited availability of these essential medicines in many low-income and middle-income countries.19 Universal access to healthcare and essential medicines are necessary prerequisites for rational prescribing.

Research into the availability of essential medicines in low-income and middle-income countries is to be welcomed and encouraged. There is, however, a need for other types of research in relation to rational prescribing. Tools for the evaluation of rational prescribing have been extensively developed and studied in adults, especially the elderly.20 A systematic review of rational prescribing tools in 2014 identified 46 tools for adults.20 In contrast, a systematic review in 2020 of tools for paediatric patients identified only three tools.21

The first tool for use in children was developed in France. Pediatrics: Omission of Prescriptions and Inappropriate Prescriptions (POPI) was published in 2014 and contained 105 criteria to evaluate prescriptions.22 The tool was modified for use in the UK and this tool (POPI-UK) contained 80 criteria.23 The only other tool was developed for use in primary care by researchers in Ireland and contained 12 criteria, of which six were for the respiratory system.24 None of these tools are suitable for neonates and the lack of such tools for neonates has been highlighted.2 25

The evidence basis for the rational treatment of children is increasing with recognition that children have the right to receive medicines that are scientifically evaluated for efficacy and safety. Additionally, changes in teaching clinical pharmacology to medical students may promote a greater understanding of the need for rational prescribing.26 Health professionals need to ensure that the scientific evidence is used appropriately. This can only be ensured by studies evaluating prescribing habits using tools that have been validated. It is encouraging that more tools and indicators are being developed for the paediatric population. Unfortunately, considerably more needs to be done to ensure that every child receives medicines prescribed rationally.
