Epidemiologic Survey Of Acute Traumatic Brain Injury In NanChang

Objectives: To explore the epidemic feature of acute traumatic brain injury (TBI) hospitalized patients of NanChang. As we can handle the basic data of the epidemiologic` survey on TBI, it's easy for us to suggest a scientic treatment and prevention of TBI.Methods: To analyse retrospectively about the data of between year 2001 and year 2005, the cooperation system for the epidemiology survey on acute TBI in NanChang with 11 hospitals in total. An effective, complete and precise acute TBI schedule table was designed , which were filled by the special person after systemic training, in order to collect the data exactly. After that, collect the data from the TBI schedule table, and do statistic analysis with software EXCEL 2007 and SPSS 14.0.Results: The incidence of TBI from 2001 to 2005 is 132,138,143,151,137(per hundred thousand). The mortality of TBI from 2001 to 2005 is 5.68, 5.49, 7.79, 9.14, 9.41(per hundred thousand).There are 13727 cases totally acquired in this TBI epidemiologic survey in 11 hospitals between year 2001 and year 2005 in NanChang. Retrospective analysis about the data, we can find that, the male cases are 9642 with 70.24%, and female are 4085 at the ratio of 29.76%. The mainly age is raised from 16 to 45(35.08%). Of all the cases, the sequence of occupation was peasants (29.61%), workers (12.57%), students (12.06%). The major cases of the TBI are traffic accident (50.19%), then violence (17.25%) and falling (13.53%). 97.02% of the patients undergo a closed trauma of the head. For curative effect evaluation , at the time when the patients went out of the hospital, there are 11347 cases at the percents of 82.66 healing well and can go well life, 964 cases for 7.02% are moderately disabled but capable of self-care, while there are 3.12% of the patients with a number of 428 cases who are severely disabled and 1.72%(236 cases) are still in a coma. Otherwise, 752 cases with 5.48% are dead. Doχ2 test with the whole data, we can find that the mortality of the group of older than 65 in contrast with that of the groups of younger than 56 was different distinctly(P<0.05).We can also find that the mortality of mild patients was different distinctly in contrast with that of the other types patients.(P< 0.05).Conclusion: According to the survey,the three major causes of acute TBI were traffic accident, violence and falling. People at the age of 16-45 are at high risk. The age and the degree of the injury (GCS grade) show significant influence on the prognosis of acute TBI. We should do something at unifying the treatment standard, fortifying the public safety education and regulating the therapy for reducing the mortality and disability rate.
