Stroke units reduce death and disability through the provision of specialist multidisciplinary care for diagnosis, emergency treatments, normalisation of homeostasis, prevention of complications, rehabilitation and secondary prevention. All stroke patients can benefit from provision of high-quality basic medical care and some need high impact specific treatments, such as thrombolysis, that are often time dependent. A standard patient pathway should include assessment of neurological impairment, vascular risk factors, swallowing, fluid balance and nutrition, cognitive function, communication, mood disorders, continence, activities of daily living and rehabilitation goals. Good communication and shared decision making with patients and their families are key to high-quality stroke care. Patients with mild or moderate disability, who are medically stable, can continue rehabilitation at home with early supported discharge teams rather than needing a prolonged stay in hospital. National clinical guidelines and prospective audits are integral to monitoring and developing stroke services in the UK.
Stroke unitsEach year 152,000 people in the UK have a stroke.1 Randomised controlled trials and subsequent meta-analyses have clearly shown that care in a multidisciplinary stroke unit reduces death, disability and the need for institutionalisation when compared with general medical wards.2 These benefits are seen regardless of the patient's age, gender, stroke type (ie infarct or haemorrhage) or stroke severity (Fig 1 ).2 Based on a number needed to treat of 18, stroke units prevent death or dependency for 8,400 stroke patients per year.3 All acute stroke patients should be treated on a stroke unit (a ward that cares almost exclusively for stroke patients) throughout their inpatient stay unless stroke is not their predominant medical problem. Recently, stroke services in many areas have been reorganised to improve the quality and efficiency of care.5 Hyperacute stroke units (HASUs) provide > rapid specialist assessment and diagnosis on the HASU or in the associated accident and emergency department > hyperacute treatment, eg thrombolysis > physiological and neurological monitoring > early rehabilitation.Stroke patients usually remain on a HASU for up to 72 hours and are then transferred to an acute stroke unit or stroke rehabilitation unit. Some stroke services have a comprehensive
