Focus on dementia - January 2016
Publication date: 09:30 January 19, 2016
This publication takes information from a variety of sources to provide a compendium of statistics about dementia in England.
It provides both new analysis and previously published statistics. New analysis includes linked mental health and mortality data, and longitudinally linked hospital data.
The publication aims to be of interest to a range of audiences, including policy makers, commissioners, researchers, patients and carers.
The publication looks at five aspects of dementia care broadly aligned to national strategic aims:
- Preventing well
Dementia and mortality
There is evidence that some factors - particularly around cardiovascular risk - can impact on the risk of developing dementia. To have their greatest impact on reducing dementia risk these factors should be controlled throughout middle age (45-64).
Diagnosis information is collected from GP practices to give a national picture of the prevalence of diagnosed dementia:
Diagnosed prevalence increased from 643 per 100,000 in April 2014 to 755 per 100,000 in December 2015, which is 423,000 diagnoses out of 56.0m registered patients.
Recording inconsistencies are found in nearly half of inpatient admissions for people previously recorded as having dementia.
Carers of people with dementia assess their own quality of life as 7.7 out of 12 overall. This is lowest in London at 7.3 and highest in the North East at 8.4.
39 per cent of carers spent 100 or more hours each week looking after or caring for a person with dementia, with 52 per cent spending 50 hours or more per week.
Over half (51 per cent) of carers had been in their caring role for more than five years.
Prescriptions of the four National Institute for Health and Care Excellence (NICE) appraised Alzheimer's disease (the commonest cause of dementia) medicines increased from 502,000 items in 2004 to 3.0 million items in 2014
At the end of September 2015, there were 109,000 assignments to one of the three mental health care clusters covering cognitive impairment or dementia at:
or high physical need or engagement
Looking at all records from April 2012 to March 2015;
The median time for progression between 'moderate need' and 'high need' is 3 years and 2 months.
The median time for progression between 'high need' and 'high physical need of engagement' is 2 years and 9 months.
Dementia and mortality
We analysed the mental health data linked to ONS mortality data to provide information on progression between dementia associated care clusters and death.
The results of the survival analysis provide a median survival time of 3 years 6 months, from when patients are first assessed as having 'cognitive impairment or dementia at moderate need'.
Median survival from first assessment with 'cognitive impairment or dementia at high need' is 2 year 3 months.
Median survival from first assessment with 'cognitive impairment or dementia at high physical need or engagement' is 1 year and 8 months
