Burden of Stroke in India During 1960 to 2018: A Systematic Review and Meta-Analysis of Community Based Surveys.

Background: Stroke is a heterogeneous disorder comprising of clinical subtypes and many risk factors, also alluded to as cerebrovascular disorders (CVDs). Increase in the global burden of stroke in developed and developing countries has been alarming. To galvanize the efforts towards the prevention and treatment, there is a need for robust data on the burden of stroke. Objective: The aim of this study was to estimate the burden of stroke, a systematic review of community-based studies was conducted. Material and Methods: Systematic search of PubMed and Google Scholar for studies from January 1960 to December 2018 was done. The articles were screened and the data was retrieved and sorted into incidence, prevalence and mortality rates. Meta-analysis was done on Medcalc statistical software version 19.2.6. Results: Prevalence rate of stroke for total population inclusive of urban and rural population, varied from 44.54 to 150/100000.For the urban population prevalence rate was 45 to 487/100000 and 55 to 388.4/100000 for rural population. The incidence rate varied from 33 to 123/100000 in the urban population and in the rural population it was estimated to be 123.57/100000. The 30 days case fatality rate of stroke varied from 41.08% to 42.06% in urban population and 18% to 46.3%.in the rural population. Conclusions: Systematic review and meta-analysis reveal that the stroke burden in India is quite high.
