ABSTRACT
To investigate trend and seasonal pattern of occurrence and mortality of motorcycle accidents in patients referred to hospitals of Isfahan
Methods: This cross-sectional study was carried out using traffic accidents data of Isfahan province, extracted from Ministry of Health [MOH] database from 2006 to 2010. During the study period, 83648 people injured due to motorcycle traffic accidents were referred to hospitals, all of them entered in the study. Logistic regression model was used to calculate the hospital mortality odds ratio, and Cochrane-Armitage test was used for assessment of linear trend
Results: During the study period, the hospital admission for motorcycle accident was 83,648 and 89.3% [74743] of them were men. Mean age in accidents time was 26.41+/-14.3 years. The injuries and death sex ratio were 8.4 and 16.9, respectively. Lowest admission rate was during autumn and highest during summer. The injury mortality odds ratio was 1.01 [CI 95% 0.73-1.39] in the Spring, 1.34 [CI95% 1.01-1.79] in summer and 1.17 [CI95% 0.83-1.63]. It was also calculated to be 2.51 [CI95% 1.36-4.64] in age group 40-49, 2.39 [CI95% 1.51- 5.68] in 50-59 and 4.79 [CI95% 2.49-9.22] in 60-69 years. The mortality odds ratio was 3.53 [CI95% 2.77-4.5] in rural place, 1.33 [CI95% 1.15-1.54] in men, and 2.44 [CI95% 2.09-2.85] in the road out of town and village. In addition, trend of motorcycle accidents mortality was increasing [p<0.001]
Conclusion: Motorcycle accidents injuries are more common in men, summer, young age and rural roads. These high risk groups need more attention, care and higher training
ABSTRACT
The purpose of this study is detecting short-term survival of all hospitalized patients with acute myocardial infarction in Isfahan and Najaf Abad based on sex. The data of all patients who were hospitalized with acute myocardial infarction between 1378 to 1387 in Isfahan and Najaf Abad were collected by trained nurses of the surveillance department in a research center. Using these information and Cox proportional hazard method, Kaplan-Meier method and log Rank test, the survival by sex in different subgroups of patients, was determined and compared between two sexes. Short-term 28 days survival following the occurrence of acute myocardial infarction is 90.9%. A significant difference was seen between overall women and men survival [Respectively, 86.7% vs. 92.5% p<0.001]. It decreases significantly with increasing age and increases with thrombolytic use. The survival rate of acute myocardial infarction in Iranian women is less than men. Physicians should pay more attention to the treatment and care of patients at higher risk of mortality, especially women and older patients
