Abstract

Sleep disorders in childhood are common. Melatonin is prescribed by UK community paediatricians to treat sleep disorders, but practice is not standardised. This audit reviewed melatonin prescribing within a community paediatric department in a 12-month period. 682 children received melatonin prescriptions; a random sample of 198 records were reviewed. The most common underlying condition was autism spectrum disorder (ASD) in 28%. 41% had no underlying diagnosis when melatonin was initiated and were waiting for neurodevelopmental/ASD assessment. 42% were on melatonin for at least 2 years. Further work is required to optimise melatonin prescribing practice for children and young people.

Statistics from Altmetric.com

Up to 40% of children experience sleep problems during childhood. This increases to 86% for children with additional needs, including neurodevelopmental disorders such as autism spectrum disorder (ASD).1

Melatonin is frequently prescribed by community paediatricians in the UK to treat sleep disorders in children. There is no national guidance regarding the prescribing of melatonin for sleep difficulties in children, but a research study by Gringras et al demonstrated its effectiveness for children with ASD.2

The purpose of this audit was to review current practice relating to the prescribing of melatonin by community paediatricians, within an acute trust in the West Midlands, UK.

Retrospective data were collected. A list of all melatonin prescriptions dispensed for patients aged 0–16 years between 1 August 2017 and 31 July 2018 was obtained from the hospital pharmacy. A random sample was selected; outpatient clinic letters available in electronic medical records of those selected were reviewed. Data were logged on an excel database.

Data variables collected included dose, formulation, duration, diagnosis.

Patient and public involvement

Patients were not involved in this project.

A total of 2423 melatonin prescriptions for 682 children were dispensed during the study period. Of 205 (30%) electronic medical records were randomly selected for review, seven prescribed by general paediatricians were excluded.

Of 81/198 (41%) children had no diagnosed condition when starting melatonin, many were on waiting lists for ASD assessments, others being monitored by community paediatricians without further neurodevelopmental assessment planned.

The most common diagnosis was ASD in 55 children (28 %) (figure 1). In our trust, children with attention-deficit hyperactivity disorder are managed by mental health services not paediatricians.

There were 22 different dosing regimens and four different preparations prescribed (liquid, capsules, tablets, modified-release tablets). Seventy-seven children (39%) were on doses of 3 mg or less. There were several cases where doses of 10 mg or more had previously been used and subsequently reduced. Current prescriptions for 194 (98%) of cases were for doses less than 10 mg.

Eighty-six (43%) children had been on melatonin for at least 2 years (figure 2).

How long ago was melatonin commenced?

This audit shows that multiple different prescribing practices are used for melatonin by community paediatricians within the same department. Children remain on melatonin for years and the majority of these children require appointments in secondary care medical clinics to review this.

At the time of this audit, there was no licensed paediatric melatonin product. Slenyto has since been licensed for use in children with ASD, but 41% of prescriptions were for children with no underlying diagnosis or awaiting assessment. It is recognised nationally that waiting lists for ASD assessments are lengthy, but sleep specialists recommend avoiding melatonin for children mid-assessment.3 There remains a large cohort of children that have conditions where melatonin is not licensed but recognised to be of clinical benefit.4

Advice on sleep hygiene is given at medical appointments, but the department relied heavily on melatonin to manage sleep problems, there was no specialist sleep service and little behavioural support available to families; reflecting community paediatric practice in much of the UK. There is evidence that good sleep hygiene alone can result in better sleep in childhood, and access to support can reduce reliance on medication.5

Community paediatric departments should explore options for increasing behavioural intervention to further reduce the emphasis on medication for sleep difficulties in children. Where medication use is unavoidable, we recommend that further work is undertaken to develop clear guidelines to optimise the management of melatonin prescribing for children.

We suggest that melatonin management could be better achieved in dedicated sleep clinics; potentially nurse-led. Alternatively, primary care could take over the management for children with sleep difficulties who do not require specialist follow-up, but it would be important to ensure they have access to behavioural advice.
