Feasibility study of stroke surveillance: Data from Bangalore, India.
Article Dans Anglais | IMSEAR | ID: sea-135910
ABSTRACT
Background &

objectives:

Stroke is a leading cause of deaths, and disabilities in India. Reliable and good quality data on epidemiological characteristics of stroke are essential to plan, implement and evaluate stroke prevention and control programmes. A feasibility study was undertaken in Bangalore to examine the possibility of establishing stroke surveillance and to develop methodology for a larger programme.

Methods:

The study adapted WHO STEPs-STROKE methodology to collect data on hospitalized stroke events and fatal stroke events in the city of Bangalore. In STEP I, Information was collected from 1,174 stroke patients in three large hospitals and were followed till discharge and 28 days; outcome was measured as death or disability. Stroke cases fulfilling diagnostic criteria, evaluated by neurologists and CT/MRI confirmed cases were included. Brief information on major risk factors was collected from all stroke patients / family members and from medical records by trained research officers. In STEP II, death records of Bangalore Mahanagara Palike for 2004 (n=23,312) were analyzed to identify stroke related deaths.

Results:

Using WHO-STEPs approach, a methodology was developed for stroke surveillance in a geographically defined population. By STEP 1 method - 7 per cent of medical and 45 per cent of neurological admissions were due to stroke with a fatality rate of 9 per cent at hospital discharge and 20 per cent at 28 days. With a mean age of 54.5 (± 17.0) yr and male preponderance, nearly half had one or more risk factors. Weakness or paresis (92%) was the commonest presentation and ischaemic stroke was most frequent (73.8%). One third of total stroke patients were dependent at both discharge and 28 day follow up. By STEP II method the proportional mortality rate for Bangalore city was observed to be 6 per cent and more than 50 per cent of total stroke deaths had occurred in 10 major hospitals. Interpretation &

conclusions:

The present study has shown that stroke surveillance is possible and feasible. Institution based (hospitals and vital registry data) stroke surveillance supplemented with periodical population based information can provide comprehensive information on vital aspects of stroke like mortality, risk factors, disability and outcome. There is a need to develop stroke surveillance in a phased manner along with mechanisms to apply data for prevention and control programmes.
