Acute stroke clinical care standard indicators: 5a-Separation on antihypertensive medication for haemorrhagic stroke
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||Indicator 5a-Separation on antihypertensive medication for haemorrhagic stroke|
|Registration status:||Health, Candidate 14/03/2017|
Proportion of patients with a final diagnosis of haemorrhagic stroke on antihypertensive medication, where not contraindicated, on separation from hospital.
Hypertension is the strongest modifiable risk factor for recurrent stroke, and the efficacy of antihypertensive medication to prevent stroke recurrence has been demonstrated (Lakhan & Sapko 2009).
Reduction in blood pressure, irrespective of initial blood pressure, has been shown to reduce the recurrence of stroke and combined vascular events including myocardial infarction (ACHS 2015).

Collection and usage attributes
Both the numerator and the denominator include patients with a final diagnosis of haemorrhagic stroke.
The numerator requires evidence of prescription and administration of an antihypertensive agent prior to separation.
Both the numerator and the denominator exclude patients for whom antihypertensives are contraindicated (where the contraindication is clearly documented). Contraindications for antihypertensives may include:
Presented as a percentage.
(Numerator ÷ denominator) x 100
Number of patients with a final diagnosis of haemorrhagic stroke on antihypertensive medication on separation from hospital.
Number of patients with a final diagnosis of haemorrhagic stroke separated from hospital.
Note that this indicator is also relevant to ischaemic stroke. However, a more specific indicator for ischaemic stroke has been included in the Clinical care standard indicators: acute stroke indicator set.
