Recorded Dementia Diagnoses 2016/17

July 17, 2017

The latest statistics on dementia prevalence in England have been published by NHS Digital. The annual report brings together GP-level data on recorded dementia diagnoses.

Recorded Dementia Diagnoses 2016/17 uses information provided by general practices in England about the number of dementia diagnoses in their individual practice.

The Department of Health, on behalf of the Secretary of State for Health and NHS England, directed NHS Digital to establish this data collection in order to receive specific dementia diagnosis data. These data support the Prime Minister's challenge on dementia 2020, which aims to improve the national diagnosis rate of dementia.

For each general practice included in this data collection, NHS Digital receives a count of the number of patients with a dementia diagnosis in their clinical record, as well as a count of the total number of registered patients at the practice.

In 2016-17, it reports that:

  • 422,000 people aged 65 and over in England have a recorded dementia diagnosis. This represents 1 in 23 people aged 65+ registered with a GP.
  • 1 in 5 women aged 90 or over have a recorded dementia diagnosis, the highest prevalence for any group.
  • There were 207,797 unique patients aged 65 and over admitted to hospital in an emergency with a diagnosis of dementia (provisional data).
  • Dementia is more common in people with learning disabilities, particularly for individuals with Down's syndrome who appear to develop dementia at younger ages.

The report also covers topics such as:

  • Dementia-related emergency hospital admissions (England).
  • Dementia prevalence for patients with learning disabilities.
  • Recorded dementia diagnoses by ethnicity and age.

A separate monthly report is also being published, which includes dementia prevalence figures at a national, sub-national, regional and general practice level.

Key facts in this report include:

  • Recorded dementia prevalence at 30th June 2017 is 0.770% (1 person in 130).
  • When considered alongside monthly data previously collected, this indicates a progressive increase in recorded prevalence from June 2016 (0.763) to June 2017 (0.770).
  • After adjustments to remove spurious, 'non-GP' practices, shared practices and practices which decided not to participate in this extraction, the extract cohort available for collection was 7,284 practices.
  • Of the extract cohort, data for 7,233 practices were collected, representing 99.3% coverage of cohort practices.
  • 75.0% of patients on the practices' dementia registers had their ethnicity recorded as either 'Not stated' or 'No ethnicity code'.
