Improvement in Survival after Stroke -- MEDICA - World Forum for Medicine

In three separate studies between 1981 and 2003, researchers investigated the rate of short and medium-term survival after stroke and found that the probability of survival increased from 1981, especially in the 28-day period following a stroke. According to Principal Investigator, Professor Craig Anderson, Director of the Neurological and Mental Health Division at The George Institute, the rate of hospitalisation, brain imaging (CT or MRI scans) and medical attention have all increased dramatically over the period.

"In 1981, 64% of patients were admitted to hospital and 13% would have brain imaging. In 2003, 92% of patients were being admitted to hospital with 90% receiving scans. This improved level of stroke care has directly benefited stroke sufferers across New Zealand."

However, as the death rate declines, there has been a significant increase in the number of patients with an impaired level of consciousness and motor deficits following stroke. Dr Kristie Carter, Research Fellow for the study noted that, "We found that a person´s level of consciousness at the time of stroke, age and history of pre-morbid dependency, were strong predictors of survival".

"The increased number of stroke survivors in New Zealand is a positive outcome, showing more knowledge of the condition and how to treat it," says Associate Professor Valery Feigin of The University of Auckland´s Clinical Trials Research Unit. "However, this also puts an additional burden on resources, both family and community. More needs to be done in preventing strokes and implementing evidence-based management and rehabilitation strategies (for example, Acute Stroke Units).”; Source: Research Australia
