Premature mortality (childhood)

Infant mortality rate is expressed as the number of deaths of infants aged under 1 year per 1,000 live births. Nationally, the latest infant mortality data available (using pooled data from January 2012 to December 2014) shows that there were 4 deaths per 1,000 live births to infants in the first year of life. In West Sussex, during the same period, there were 3.4 deaths per 1,000 live births and this is statistically similar to the England rate.

In 2012-14 there were 28 deaths among infants under the age of 1 who were resident in Horsham and Mid Sussex districts. The trend in infant mortality rate for Horsham and for Mid Sussex between 2008-10 and 2012-14 are given in the chart below. The number of deaths at district level are generally very small and as such, estimates are accompanied by large confidence intervals indicating that there may be little or no change over time. In 2012-14, the directly age-standardised rate or infant mortality in Horsham was 3.7 deaths per 1,000 live births (95% CI: 2.0 – 6.2 deaths), which is not significantly different to West Sussex, the South East region, or England. In Mid Sussex, the directly age-standardised rate of infant mortality was 3.1 deaths per 1,000 live births (95% CI: 1.7 – 5.1 deaths) which again is statistically similar to West Sussex, region, and national figures.

Infant mortality has only recently been published at the CCG level and so it is not possible yet to explore differences over time. However, for the pooled year 2012-2014, the crude infant mortality rate in NHS Horsham and Mid Sussex CCG was 3.7 deaths per 1,000 live births (95% CI: 2.4 – 5.4 deaths per 1,000). This is not significantly different from NHS Coastal West Sussex CCG (3.5 deaths per 1,000 live births, 95% CI: 2.6 – 4.6), NHS Crawley CCG (2.6 deaths per 1,000 live births, 95% CI: 1.4 – 4.5 deaths) or England (4 deaths per 1,000 live births, 95% CI: 3.9 – 4.1 deaths).

Child Mortality
After the age of one year, injury is the most common cause of death in young people; and many of these injuries are potentially avoidable. At CCG level child mortality statistics include the number of deaths to those aged 1 year to 17 years per 100,000 European Standard Population (2013 ESP). Data is currently only available for the period 2012-14 and this indicates that there were 12 deaths among children aged 1 year to 17 years in NHS Horsham and Mid Sussex CCG at a rate of 8.2 deaths per 100,000 ESP 2013 (95% CI: 4.2 – 14.3 deaths). This was not significantly different to the rate for NHS Coastal West Sussex CCG (8.9 deaths per 100,000 ESP 2013, 95% CI: 5.7 – 13.4), NHS Crawley CCG (5.3 deaths per 100,000 ESP 2013, 95% CI: 1.4 – 13.6 deaths) or England (12 deaths per 100,000 ESP 2013, 95% CI: 11.6 – 12.3 deaths). The small number of deaths, as reflected in the large confidence intervals, indicate that the estimates of mortality are highly variable.
