Excess under-75 mortality in adults with serious mental illness
The first domain of the NHS Outcomes Framework captures how successful the NHS is in reducing the number of avoidable deaths. One area for improvement in this domain is to reduce premature mortality in people with serious mental illness. This indicator measures the extent to which adults with a serious mental illness die younger than adults in the general population.
The indicator value is the indirectly standardised ratio (expressed as a percentage) of the observed number of deaths of adults aged 18 to 74 in contact with secondary mental health services to the expected number of deaths in that population based on age- and sex-specific mortality rates in the general population.
The mental health mortality rate is directly age and sex standardised to the national population. This is then compared to the general population mortality rate using a standardised mortality ratio.
The mental health population is defined as anyone who has been in contact with secondary mental care services in the current financial year or in either of the two previous financial years who is alive at the beginning of the current financial year.
This indicator uses data from the Mental Health Minimum Data Set, the Primary Care Mortality Database and Office for National Statistics (ONS) population estimates.
