INTRODUCTIONEarlier treatment with intravenous stroke thrombolysis improves outcomes and lowers risk of bleeding complications. The decision-making and consent process is one of the rate-limiting steps in the duration between hospital arrival and treatment initiation. We aim to describe the attitudes and practices of neurologists in Singapore on the consent and decision-making processes for stroke thrombolysis.
MATERIALS AND METHODSA survey of neurologists and neurologists-in-training in 2 large tertiary public hospitals in Singapore was conducted.
RESULTSAmong 46 respondents, 94% of them considered stroke thrombolysis an emergency treatment and 67% of them indicated there is a need for written informed consent. The majority (87%) knew that from a legal perspective, the doctor should be the decision-maker in an emergency treatment for a mentally incapacitated patient. However, 63% of respondents reported that it is the next-of-kin who usually makes the decision in actual practice. If confronted with a mentally incapacitated stroke patient, 57% of them were willing to be the proxy decision-maker and 13% of them were not. In 3 commonly encountered vignettes when a mentally incapacitated patient was being considered for stroke thrombolysis, there was no clear consensus on the respondents' practices.
CONCLUSIONThe next-of-kin is usually the decision-maker for stroke thrombolysis in practice for a mentally incapacitated patient despite most doctors considering thrombolysis an emergency treatment. This, together with the lack of consensus and variance in decision-making and consent practice amongst neurologists for stroke thrombolysis, demonstrates the need to develop best practice guidelines to standardise healthcare practices for greater consistency in health service delivery.

INTRODUCTIONIntravenous tissue plasminogen activator (tPA) within 3 hours of stroke onset is a licensed proven therapy for ischaemic stroke, with recent trial data showing benefit up to 4.5 hours. We previously published in this journal data of a survey conducted in 2004 showing only 9% of ischaemic stroke patients presenting to the Singapore General Hospital (SGH) arrived within 2 hours of onset. We aimed to determine whether the problem of delayed hospital arrival persists in 2009 and to establish the impact of widening the time window for intravenous tPA to 4.5 hours.
MATERIALS AND METHODSWe prospectively surveyed consecutive ischaemic stroke patients admitted to the SGH from 9th March to 30th April 2009. Patients and/or relatives were interviewed with a standardised form similar to the 2004 survey.
RESULTSAmong the 146 ischaemic stroke patients surveyed (median age 67 years, 59% male, median NIHSS score 2), 6% presented to SGH within 2 hours and 15% within 3.5 hours of onset. Median time from stroke onset to hospital arrival was 1245 minutes (20.75 hours). Pre-hospital consultation was significantly associated with hospital arrival after 2 hours from onset. Main reasons cited for delay were not realising the gravity of symptoms (31%) and not recognising them as stroke (27%).
CONCLUSIONDelayed arrival to SGH following acute ischaemic stroke remains a problem in 2009. This confirms the lack of stroke awareness in Singapore and highlights the need for public stroke education. Furthermore, these data confirm that widening the time window for intravenous tPA treatment to 4.5 hours at SGH will increase its utilisation.
