RESUMO
Objective To introduce practice efficacy and achievement of medical waste management project in medical institutions.Methods Twenty pilot medical institutions in 6 provinces and 1 520 extended medical institutions in each provinces (municipality, city) in China were selected to perform medical waste management project, the current situation of medical waste management in China was explored to develop a new feasibility plan and practice.ResultsCatalogue of medical waste classification (revised manuscript) and Medical waste classification collection list) were formulated, which enhanced supervision ability of medical and health administration on medical waste management.Medical waste management training system was established, best available techniques/best environmental practices(BAT/BEP)for medical waste management were achieved, cooperation and promotion ability of medical waste management project was strengthened.Conclusion Medical waste management project has made great achievements since it is implemented in medical institutions, the achievement can be used as reference for medical waste management in China.
RESUMO
<p><b>OBJECTIVE</b>To investigate the survival time and affecting factors among AIDS patients under antiretroviral treatment, between 2008 and 2013 in Liangshan, Sichuan province.</p><p><b>METHODS</b>Observational retrospective cohort study method was applied. AIDS patients were chosen from China's national comprehensive prevention and control management system of AIDS in Liangshan, during 2008-2013. Related information on demographics, source of infection, pathogenesis, treatment and death was collected. Cox proportional hazards model was applied to analyze the factors that might affect the survival on patients.</p><p><b>RESULTS</b>Among the 8 321 cases, ranging from 18 to 87.5 years old (mean age as 34.2 ± 9.8), 3 021 died and 3 721 patients had received HAART treatment. The total mortality rate dropped from 43.9/100 person-years to 20.7/100 person-years from 2008 to 2013. In the treatment group, mortality rate dropped from 27.3/100 person-years to 5.1/100 person-years, while in the untreated group it remained high-between 45.0/100-50.8/100 person-years. Proportion for the treatment coverage increased gradually, from 5.8% in 2008 to 54.5% in 2013. Median survival time of all the AIDS patients was 35.1 months, but 18.4 months in the untreated group. Survival of all the AIDS patients was associated with factors as: treatment, age when AIDS diagnosis was made and route of HIV infection (P < 0.05). The risk of death among untreated patients was 5.78 times to the treated ones, but did not seem to relate to gender or nationality (P > 0.05). Survival of the treated group was associated with factors as gender, age when AIDS diagnosis was made, nationality, route of HIV infection, CD4(+) T cell count when AIDS diagnosis was made, CD4(+) T cell count at treatment baseline, anemia at the treatment baseline (P < 0.05). Survival of the untreated group was mainly associated with age when AIDS was diagnosed (P < 0.05) while other factors did not seem to be significantly related (P > 0.05).</p><p><b>CONCLUSION</b>Antiretroviral therapy appeared an important factor that affecting the survival of AIDS patients, timely treatment and CD4(+) T cell count provided at the baseline for treatment, were two key factors that affecting the outcome of treatment. Our findings pointed out that tactic factors as: strengthening the detection, monitoring on CD4(+) T cell count, early diagnose and treatment, expanding the coverage of antiretroviral therapy, and appropriate timing for treatment etc., were important ways to enhance the effects of treatment, so as to reduce the mortality rate and prolong the time of survival.</p>
