Cerebrovascular Disease Surveillance Based On Discharge Abstract Database

ObjectiveFrom the monitoring information of discharged patients with cerebrovasculardisease in Beijing, we purposed to establish a surveillance method for it, achieve theepidemiological distribution characteristics and provide suggestions for making thedecision on prevention and control of cerebrovascular disease.Data and methodsData was get from the Beijing Hospital Discharge Information System, conductedby Beijing Public Health Information Center. We extracted the data ofcerebrovascular disease in2007-2009and analyzed on epidemiological distributioncharacteristics through description analysis.Results The integrity and diagnosis accuracy of Beijing Hospital DischargeRegister Database was well.There were109829、120761、131978inpatients withcerebrovascular disease in Beijing in the year of20092010and2011respectively.From2009to2011, the average age of inpatients with cerebrovascular disease was（65.26±13.68）,（65.66±13.47）and（65.95±13.48）years old respectively,there was no statistically significant difference (F=0.14, P=0.79).The proportion ofmen with cerebrovascular disease was higher than women. The proportion of cerebralinfarction was50%and transient ischemic attack was close to20%. There was asignificant decreasing trend about the case-fatality in hospital of patients withcerebral infarction and cerebral hemorrhage but subarachnoid hemorrhage did nothave a trend. Patient admitted to hospital on weekend were more likely to die thanweekday. There was a peak seasons that patients entered hospital when there was seasonal variation.Conclusion It is feasible for Beijing to establish the Hospital Discharge RegisterDatabase.The patients with cerebrovascular disease in Beijing was younger. Theformation of cerebrovascular disease in Beijing was like the developed countries.There was a significant decreasing trend about the case-fatality in hospital of patientswith cerebral infarction and cerebral hemorrhage but subarachnoid hemorrhage didnot have a trend. Patient admitted to hospital on weekend were more likely to die thanweekday. There was a peak seasons that patients entered hospital when there wasseasonal variation. I made this study in order to provide suggestions for making thedecision on prevention and control of cerebrovascular disease.
