[Epidemiologic data of stroke. Data of the WHO-MONICA Project in Germany].
Analyses of stroke morbidity or mortality are usually based on official statistics. A reduction in stroke mortality rates has been shown for many countries. It is not clear, however, whether this is due to declining morbidity or case fatality (or both). For this purposes population-based register data are required. Using the standardized methodology of the WHO-MONICA Project, stroke cases were also registered in Germany from 1984 to 1993 (7,435 first-ever and recurrent stroke cases). The data collection was almost restricted to East Germany. The age-specific stroke rates in males/females showed an increase from 9/11 per 100,000 population in the youngest age group (25-34) to 1,005/779 cases per year in the oldest group under study (65-74). If one tries to classify stroke types, which is not always possible in a population-based register, the best estimate for men (women) would be: 63(62%) thromboembolic stroke, 25(22)% intracerebral hemorrhage, and 12(17)% subarachnoid hemorrhage. The 28-day case fatality of the 25-74 year old stroke patients was found to be about 40%. Neither for stroke attacks nor for case fatality was a convincing time trend over the 10-year period found. The very small changes observed over 10 years time should lead to increased attention to strokes, particularly primary and secondary prevention, and this not only in East Germany. This applies also for treatment in the acute phase, because the case fatality before admission in the hospital and during the first few days is still very high. Population-based studies of the long-term prognosis of stroke patients in Germany are also missing, i.e., including the effectiveness of various forms of treatment and rehabilitation. Systematic monitoring of the development in this field is an important part of the assessment of the quality and effectiveness of the health care service.
