Surveys of Stroke Patients and Their Next of Kin on Their Opinions towards Decision-Making and Consent for Stroke Thrombolysis

Ann Acad Med Singap. 2017 Feb;46(2):50-63.

Abstract

Introduction: Early initiation of stroke thrombolysis is associated with improved outcomes. Procurement of consent is a key factor in prolonging the door-to-needle duration. This study aimed to determine the attitudes and preferences of stroke patients and their next of kin (NOK) towards decision-making for stroke thrombolysis in Singapore.

Materials and methods: We surveyed acute ischaemic stroke patients (n = 171) who presented beyond the 4.5-hour therapeutic window and their NOK (n = 140) using a questionnaire with scenarios on obtaining consent for intravenous thrombolysis.

Results: In the patient survey, 83% were agreeable for their NOK to decide on their behalf if mentally incapacitated and 74% were agreeable for the doctor to decide if the NOK was absent. In the NOK survey, the majority (81%) wanted to be consulted before mentally capacitated patients made their decision; 72% and 74%, meanwhile, were willing to decide on behalf of a mentally capacitated and mentally incapacitated patient, respectively. In the scenario where a doctor recommended a mentally incapacitated stroke patient to undergo thrombolysis but the family declined, there was a near equal split in preference to follow the family's or doctor's decision in both the patient and NOK surveys.

Conclusion: The survey found that in the decision-making process for stroke thrombolysis, there was no clear consensus on the preference for the decision maker of the mentally incapacitated patient. In Singapore, there is a strong influence of the NOK in decision-making for thrombolysis.
