Excess winter deaths

The most common causes of excess winter deaths are cerebrovascular diseases, ischaemic heart disease and respiratory disease, with the majority of excess winter deaths occurring among older people. In England, there is evidence that colder homes are associated with higher levels of excess winter deaths from cardiovascular disease.  Physiological evidence indicates that colder home temperatures can raise blood pressure among some older people, increasing the risk of a cardiovascular event. Poorly insulated homes and lack of access to mains gas can contribute to fuel poverty; something that has been linked to excess winter deaths.  Herefordshire has a greater proportion of households living in fuel poverty than England as a whole.

The excess winter deaths index is calculated as a ratio of deaths occurring over the four month winter period (December to March) compared with the expected number of deaths, based on the average number of deaths observed in the non-winter period.

Between 2001/02 and 2014/15 there has been considerable variability in the number of excess winter deaths in Herefordshire. The lowest number being 22 deaths in 2012/13 and the highest being 225 deaths in 2014/15. Herefordshire’s single year excess winter deaths index has been similar to England’s index from 2001/02 to 2014/15 inclusive.

In 2014/15 Herefordshire’s excess winter deaths index was significantly higher than that observed in the previous three years. This trend was in line with what was observed nationally. Following statistical investigation, the Office for National Statistics concluded that the observed spike in excess winter deaths in the UK in 2014/15 was largely due to moderate levels of influenza in the community caused by low influenza vaccination effectiveness (34% effectiveness) and the dominant flu strain being influenza A(H3N2), a strain which is particularly virulent in older people. Provisional data for 2015/16 suggests that the national and regional excess winter deaths index were lower, and back in line with average trends.
