Objective To investigate the epidemiological characteristics of patients with craniocerebral injury in primary level hospital of Pearl River Delta and provide evidences for developing reasonable prevention and management policy of this disease. Methods The gender,age,injury time,occupation,injury mechanism, injury information,the relation between the craniocerebral injury and the alcohol drink in the 1 898 patients with craniocerebral injury admitted to Changping People's Hospital of Dongguan in Guangdong Province were analyzed with descriptive epidemiological method. Results There were more male cases with craniocerebral injury than in female ones(1 402 cases vs. 496 cases). The major group of craniocerebral injury consisted of patients aged between 20 to 39 years old〔1088 cases(57.32%)〕. The incidence of the injury in productive workers was higher than that of employees in other kinds of work〔57.48%(1 091 cases)vs. 42.52%(807 cases)〕. The incidences of such cases were the highest between March to May〔28.71%(545 cases)〕and in October〔9.69%(184 cases)〕,December〔11.22%(213 cases)〕than those in other months. The peak days of the incidence in a week were Saturday〔392 cases(20.65%)〕and Sunday〔375 cases(19.77%)〕,but the rate of Thursday was the lowest〔201 cases(10.59%)〕. The peak time in a day was between 18 to 24 o'clock〔961 cases(50.63%)〕. Traffic accident was the leading cause of the injury accounting for 52.95%. The incidence of mild to moderate craniocerebral injury(79.98%)was much higher than that of severe and especially severe injury(20.02%). The alcohol drink was bound up with craniocerebral injury. Conclusion The occurrence of craniocerebral injury has certain regularities concerning the respects of patients' gender, age, occupation,injury time,injury mechanism,types of injury,etc and based on the epidemiological characteristics,a proper management policy should be taken to effectively reduce the morbidity of craniocerebral injury.
