Dementia: target organ damage (all patients)

Indicator type

The new indicator replaces the 2013/14 Quality and Outcomes Framework indicator:

The percentage of patients with a new diagnosis of dementia recorded in the preceding 1 April to 31 March with a record of FBC, calcium, glucose, renal and liver function, thyroid function tests, serum vitamin B12 and folate levels recorded between 6 months before or after entering on to the register.

Rationale

The timeframe for this indicator has been amended to be consistent with a new dementia indicator NM65 (attendance at a memory assessment service).

There is no universal consensus on the appropriate diagnostic tests to be undertaken in people with suspected dementia. However, a review of 14 guidelines and consensus statements found considerable similarity in recommendations (Beck et al. 2000). The main reason for undertaking investigations in a person with suspected dementia is to exclude a potentially reversible or modifying cause for the dementia and to help exclude other diagnoses (such as delirium). Reversible or modifying causes include metabolic and endocrine abnormalities (for example, vitamin B₁₂ and folate deficiency, hypothyroidism, diabetes and disorders of calcium metabolism).

The NICE clnical guideline on dementia (NICE clinical guideline 42) states that a basic dementia screen should be performed at the time of presentation, usually within primary care. It should include:
