Abstract:

Objective To understand the epidemiological and medical risk profile of inpatients with cerebrovascular disease in Beijing, e.g., distribution of age, gender, stroke subtype, and prognosis, disease burden and medical quality, and provide evidence for make strategy for cerebrovascular disease prevention and treatment, and to evaluate the effectiveness of its prevention and treatment.Methods The data was obtained from "The Database of Inpatient Record from Level 2 and 3 hospitals" administered by Beijing Public Health information Center. Data of cerebrovascular disease in 2007-2009 were analyzed on demographic, disease characteristics, prognosis and health economic indicators through description analysis. Furthermore, the trend on changes over years was statistically tested.Results In the year of 2007, 2008 and 2009, there were 87 729, 99 369 and 109 829 inpatients diagnosed as cerebrovascular disease, respectively. The average age was (65.29±13.56), (65.29±13.47) and (65.26±13.68)years old for 2007, 2008 and 2009 with no significant difference (F=0.13, P=0.81). However, the proportion of patients aged from 45 to 60 showed significantly increased(Z=10.11, P<0.01).There were 59.58%, 58.6% and 58.7% of male in 2007, 2008 and 2009, respectively. As for the proportion of stroke subtype, the top five were ischemic stroke(50.0%), transient ischemic attack(20.0%), intracerebral haemorrhage(8.3%), sequelae of cerebrovasculardisease(3.0%) and subarachnoid haemorrhage(1.6%) in order. The in hospital case-fatality was 3.6%, 3.2% and 2.8% in 2007, 2008 and 2009 respectively, with a significant decreasing trend(Z=11.10, P<0.05). The median of length of hospital stay was 15-16 days, and the median of total medical cost per-person ranged from 8848 in 2007 to 9824 in 2009.Conclusion There is huge number of inpatient with cerebrovascular disease in Beijing, which leads to very heavy disease burden. Compared to developed countries, the proportion of stroke subtype is similar, whereas the average age of inpatients is much younger, and the length of hospital stay is longer. The in hospital case-fatality decreased over years. These findings would provide realizable evidence to make strategies to prevent and treatment cerebrovascular disease in Beijing, and to evaluate its effectiveness.
