| Objective Fracture is a common and unexpectable hurt, which cause deep pain and large burden to patients, their family and society. Fracture not only affect patient's quality of life, potentially loss in lives, but also damnify social labour in certain degree and cause social and individual resource waste. This report is intended to test epidemiological character of fracture and relative risk factors, confirming high risk group and establishing prevention measures can decrease incidence of fracture and deformity rate, decrease pain and economical burden brought by fracture, which can improve fracture patients and all people's quality of life. It has practical meaning .Methods Using retrospective study and cross-sectional investigation, we treated a epidemiological investigation of 2730 patients in hospital with fracture in Tianjin hospital and Hexi orthopaedics hospital, in order to find out epidemiological character hi Tianjin. On the base of descriptive analyze, we apply log-linear model and correspondence analysis to in-depth analyze data. Random select 140 the fractures as case group and 148 the non-fractures as control group to have case control study. Data was analyzed with logistic regression. To comprehensively determine the risk factors of fracture , confirming high risk group, and establishing detailed prevention measures. It can provide foundations of community health service and health education, then guide community medical and health work.Results This study is based on describes analysis. The finding shows the average age was 41.70yr, and the proportion of 15~59yr was the topmost (76.5%) , while the proportion of up to 60yr and aged 0 to 14 were the least. The occupational proportion was the worker was more than the cadre and student. The circular distribution showed there were central tendency from May to November. There was half more of the whole (54.0%) that happened on the road, some others happened in the office and home. The majority of the fracture was single fracture(74.1%). Tibia and fibula fracture were the most (16.0%), and the others were thighbone neck, kneecap and anklebone. The reasons of the fracture were traffic accident (30.5%), tumble (26.8%),falling from high(26.0%).Most of the patients were emergency treatment(88.0%)and leave hospital, most of them were on the mend(57.5%). The average hospital day (AHD) of the single facture was lower than the compound fractures, and vertebra, thighbone trunk, tibia and fibula, thighbone tubercle, thighbone neck facture's AHD are the first to the fifth. The hospitalization expenses of compound fracture was more the single facture's and the vertebra fracture is the most of each position fracture.Base on the describing analysis of the data, the log liner model was applied to analyze the age, sex, happen time of fracture. The results shows there were interaction among the age, sex, happen time of fracture. The fracture was befell on Male more than female aged 10 to 49. The 50~59yr was lower than others in October. The fracture was befell on Male in Mar, April, August and September more than other months.The log liner model was applied to analyze the age, sex, happen reason of fracture too. The results show the tumble was the main reason in female; the traffic accident was main reason of 40yr group while the tumble was the main reason in up to 60yr group.The fashion of spending was studied by the method of corresponding analysis was applied to analyze. The result shows most of the 10~20yr group spent by commercial insurance, the 30~69yr group spent mainly by social hospitalization insurance, up to 70yr spent at public health service, while the group under lOyr spent at their own expenses.The simple factor analysis showed that the risk factors for fracture patients were age, physical work, disease of bone, drink liquer, pregnancy number of times, take tranquilizer. The protective factors were milk-drinking, physical training, enough sleep.Logistic regression analysis confirmed that occurrence of fracture was mainly related... |
