An Analysis of Injury Trends and Disease Burden From Three Surveillance Hospitals in Urumqi From 2006 to 2018.

Objective: To investigate injury trends, injury distribution, and disease burden from three surveillance hospitals in Urumqi from 2006 to 2018. Method: Injury data from the National Injury Surveillance System (NISS) from three hospitals in Urumqi (2006 to 2018) were collected to analyze changes in the characteristics of outpatient injury cases. Years of potential life lost (YPLL) were calculated to determine the disease burden of the injury cases. Results: A total of 161,400 injury cases were recorded over 13 years, and the average age of the patient seeking medical attention was 32.4 years old. Male patients outnumbered female patients with a ratio of 1.6:1, but the proportion of female patients was greater after 45 years of age. The highest number of cases occurred in patients 15-29 years of age, accounting for 26.8% of all injury cases. Injury in females occurred most frequently in the home. A total of 41.4% of injury cases occurred while doing housework. The top three causes of injury were falls (49.7%), blunt force of an object, (13.7%), and motor vehicle accidents (MVA) (13.5%). Years of potential life lost from injury accounted for 7.39% of the total YPLL in the three hospitals. Conclusion: Males should be targeted for injury prevention and intervention in Urumqi. The prevention of falls, blunt force of objects, and MVA should be made a priority. Injury prevention strategies and targeted projects should be developed to reduce the disease burden of injury.

Survival analysis of HIV/AIDS patients with antiretroviral therapy among drug users in Yili Prefecture from 2005 to 2019 / 预防医学

Objective@#To understand the survival status and influencing factors of HIV/AIDS patients with highly active antiretroviral therapy ( HAART ) among drug users in Yili Prefecture, Xinjiang from 2005 to 2019, so as to provide references for reducing AIDS mortality. @*Methods @#The demographic information, clinical stage, baseline CD4+T lymphocyte ( CD4 ) level and treatment status of HIV/AIDS patients with HAART in Yili Prefecture from 2005 to 2019 were collected through AIDS Antiretroviral Therapy Information System. The survival rate was calculated by the life table method. The influencing factors for survival time were analyzed by Cox proportional hazard regression model.@*Results@#Totally 1 935 patients were recruited, the median age receiving HAART was 37 years old and the median CD4 counts was 293/μL. The cumulative survival rates at 1, 5, 7 and 10 years were 97%, 78%, 73%, and 66%, respectively. The multivariate Cox proportional hazards regression analysis showed that the patients with body mass index of 18.5-<28.0 kg/m2 ( HR: 0.391-0.656, 95%CI: 0.234-0.958 ), baseline CD4>200/μL ( HR: 0.354-0.667, 95%CI: 0.232-0.841 ) , or missed medication in the last 7 days ( HR=0.009, 95%CI: 0.001-0.061 ) had lower risk of death; the patients with WHO clinical stage of Ⅱ-Ⅳ ( HR: 1.479-2.311, 95%CI: 1.004-3.288 ) or treatment delay ≥1 years ( HR: 1.287-1.388, 95%CI: 1.029-1.826 ) had higher risk of death. @*Conclusions@#The 5-year cumulative survival rate of HIV/AIDS patients with HAART in Yili Prefecture is 78%. Body mass index, baseline CD4 level, WHO clinical stage, treatment delay and missed medication in last 7 days were the influencing factors for survival time.
