<p><strong><strong></strong></strong></p><p>The information requested falls within
the responsibility of the UK Statistics Authority. I have asked the Authority to reply.</p><p><em><strong>Letter
from John Pullinger CB, National Statistician, to Baroness Tonge, dated 07 March 2018</strong></em></p><p>Dear
Baroness Tonge,</p><p>As National Statistician and Chief Executive of the UK Statistics
Authority, I am replying to your Parliamentary Questions asking (a) whether the incidence
of neonatal mortality and morbidity has decreased over the past five years (HL5969);
(b) what was the incidence of neonatal mortality and morbidity in (1) 2000–05, (2)
2005–10, and (3) 2010–15 (HL5970); and (c) what was the incidence of neonatal mortality
and morbidity in (1) 2014–15, (2) 2015–16, and (3) 2016–17 (HL5971).</p><p>The Office
for National Statistics (ONS) is responsible for publishing statistics on deaths registered
in England and Wales. Statistics on deaths are normally published using calendar years.
Neonatal mortality figures are available for both the year the death was registered
and the year the death occurred. Comparisons over time are more meaningful using death
occurrences, to allow for delays in registering deaths. The latest year for which
death occurrence figures are available is 2015 [see note 1 below]. The neonatal mortality
figures for 2016 will be published on 14 March 2018 and the data for 2017 will be
published in early 2019.</p><p>Table 1 below provides the number of neonatal deaths
and the neonatal mortality rates per 1,000 live births for England and Wales, for
each calendar year from 2000 to 2015.</p><p>Because the number of neonatal deaths
each year is relatively small, there is likely to be some random fluctuation, and
no single year since 2000 shows a statistically significant change from the preceding
year. However, there has been a generally downward trend throughout the period. In
the five years 2011-15, the lowest neonatal mortality rate was in 2014, and this was
significantly lower than in 2011 and all previous years. The rate in 2015 was higher
than in 2014, but is still significantly lower than in 2011 (taking into account rounding
of the figures to one decimal place).</p><p>NHS Digital is responsible for publishing
statistics on NHS patient care in England. There is no widely accepted measure of
neonatal morbidity, however trends in the admission of neonates to hospital may be
useful information. Therefore, figures based on Hospital Episode Statistics (HES)
have been given here.</p><p>Table 2 below provides the number of neonatal finished
consultant episodes (FCEs) and corresponding neonatal hospitalisation rate per 1,000
live births for England, for each financial year from 2000-01 to 2016-17, and the
five-year periods 2001-02 to 2004-05, 2005-06 to 2009-10, and 2010-11 to 2014-15.
Note that HES data include activity ending in the year in question and run from April
to March, e.g. 2012-13 includes activity ending between 1st April 2012 and 31st March
2013.</p><p>Changes to the HES figures over time need to be interpreted in the context
of improvements in data quality and coverage (particularly in earlier years), improvements
in coverage of independent sector activity (particularly from 2006-07) and changes
in NHS practice. For example, apparent reductions in activity may be due to a number
of procedures which may now be undertaken in outpatient settings and so no longer
include in admitted patient HES data. Conversely, apparent increases in activity may
be due to improved recording of diagnosis or procedure information.</p><p>There has
been year on year fluctuation in the number and rate of hospital episodes for neonates
over the period of interest, but with a clear overall upward trend. The hospitalisation
rate in 2015-16 was significantly higher than five years before. However, as noted
above, it is likely that the trend is influenced to some extent by factors such as
changing clinical practice and recording.</p><p>Yours sincerely,</p><p>John Pullinger</p><p>
