Abstract:
Objective To introduce the cardio-cerebrovascular disease surveillance system and its data analysis, and provide reference for the stable and long term surveillance for the disease.
Methods Since the establishment of the surveillance system, the capability building of staff and standardized data management have been strengthened in daily work.The incidence data of the disease are reported by hospitals and collected, sorted, verified and evaluated by centers for disease control and prevention in Tianjin. The data are analyzed and transformed with software SAS and Joinpoint.
Results The underreporting rate of the surveillance system was 4.88%, and there was no significant difference between urban area and rural area. The annual case number reported increased steadily from 13 000 to over 80 000. The incidence of sudden cardiac death and intra cerebral hemorrhage showed a decline trend, while the incidence of acute myocardial infarction and cerebral infarction remained to increase, the differences were all significant (P＜0.001). Joinpoint model analysis predicted that the incidence of cerebral infarction would increase to 800/100 000 by year 2020.
Conclusion Standardized cardio-cerebrovascular disease surveillance is conducted in Tianjin, through which the disease trend and distribution can be found in time to support the effective prevention and control of cardio-cerebrovascular disease in Tianjin and provide references for other areas.
