Time Trends in Hospital-Referred Stroke and Transient Ischemic Attack: Results of a 7-Year Nationwide Survey in France

Abstract

Background: Nationwide evaluations of the burden of stroke are scarce. We aimed to evaluate trends in stroke and transient ischemic attack (TIA) hospitalization, in-hospital case fatality rates (CFRs) and mortality rates in France during 2000–2006. Methods: Hospitalizations for stroke and TIA were determined from National Hospital Discharge Diagnosis Records that used the International Classification of Disease, 10th revision, codes I60, I61, I63, I64, G45, G46. CFRs and mortality rates were estimated from the national death certificates database. Results: The total number of stays for stroke increased between 2000 and 2006 (88,371 vs. 92,118) contrasting with a decrease in that for TIA. The age-standardized (European population) hospitalization rates for TIA decreased in men (52.2 vs. 44.5/100,000/year, p = 0.002), whereas they remained stable in women (32.4 vs. 31.0/ 100,000/year). Concerning stroke, a decrease in hospitalization rates was observed in both men (from 135.3 to 123.4/ 100,000/year, p < 0.001) and women (from 85.1 to 80.7, p < 0.001). Whatever the age group and the sex, a sharp decrease in in-hospital stroke CFRs was noted. In addition, a 23% decrease in mortality rates was observed. This decrease was greater in patients >65 years. Conclusion: Our results demonstrate a decline in hospitalization rates for stroke, and in both stroke CFRs and mortality rates between 2000 and 2006. Improvements in stroke prevention and acute stroke care may have contributed to these results, and may have been initiated by recent advances in health policy with regard to this disease in France.
