CYP under outpatient care and with direct access to a member of the hospital-based team might also engage with services in a different way during the pandemic, particularly early on when little was known about the impact on this age group. We aimed, therefore, to describe patterns of urgent referrals and specialist nurse access at a UK regional paediatric neurosurgical centre in the first 6 months of 2020. For urgent referrals received by the on-call paediatric neurosurgeon, data were examined for the 6 months January-June in 2020 and the same period in 2019. A 4-year mean for the first half of the years 2016-2019 was also used for comparison, to address the likely variation between years given the small numbers. For the specialist nurse access (phone call data), a comparison was made between 2020 and 2019, and weekly data was also examined to allow for any background increase in calls in the second half of 2019. Calls were recorded as "answered", "busy" or "unanswered", and an assumption was made that they were independent events. In the first 6 months of 2020, the centre received 226 urgent referrals, a decrease of 13.1% compared with the same period in 2019 and 7.8% compared with the 4-year mean. Compared with 2019, March and May had the biggest single-month decreases in referrals, each of about a third (34.1% and 30.8%, respectively). This phenomenon was also observed when compared with the 4-year mean, although the size of the decrease was reduced to 29.7% for March and 15.3% for May. The most frequent urgent referrals, across all years, were for head injuries, including skull fractures and intracranial haemorrhages; hydrocephalus, including newly diagnosed hydrocephalus and shunt problems; and brain and spinal tumours. See Table 1 . In the first half of 2020, there were 2750 more calls to the specialist nurses than in the first half of 2019 (4291 vs 1541 calls). See Fig. 1 . For 6.1% of callers (261/4291) in 2020, the line was busy which had not been the case previously (0/3372). There were 2.8 times as many answered calls in the first 6 months of 2020 compared with the same period in 2019 (3460 versus 1258). Our data reveals that during the first 6 months of 2020, referrals to the paediatric neurosurgical inpatient team decreased, particularly in March, when compared with 2019 and the 4-year mean. This is likely due to a combination of behavioural factors and may conceal some late presentations of important and treatable pathology. In contrast, calls to the dedicated specialist nurses increased several fold reflecting concern amongst parents and carers in a globally unprecedented scenario. We acknowledge that our data is from a single centre; however, this pattern of reduced urgent inpatient referrals and increased demand for telephone advice is likely replicated across other tertiary centres around the world. This has implications for planning and delivery of services in future periods of lockdown. Proactively communicating with the parents/ carers of children known to the service is recommended to address concerns over the likely impact of COVID-19 on neurosurgical conditions.
