Increasing Burden of Stroke: The Dijon Stroke Registry (1987–2012)

Abstract

In all, 5,285 stroke cases (52.7% women) were recorded. The standardized attack rate was 98.2/100,000/year and the mortality rate was 12/100,000/year, and both were lower in women than in men (RR 0.67, p < 0.001, and RR 0.70, p < 0.001, respectively). Attack rates increased over time (RR 1.016; 95% CI 1.013-1.020) irrespective of the stroke subtype. In contrast, mortality rates declined (RR 0.985; 95% CI 0.976-0.995) with decreasing rates for ischemic stroke but no change for intracerebral hemorrhage and subarachnoid hemorrhage. The sex gap in both attack and mortality rates remained stable. Between the first (1987-1991) and the last (2007-2012) study periods, the annual number of stroke patients who survived beyond 30 days rose by 55%, Conclusions: Increasing attack rates and decreasing mortality have led to a rise in the number of stroke survivors in the population, thus indicating a growing need for the implementation of dedicated services.
