文摘Background Despite high relapse rate among methamphetamine (MA) abusers, there still have been little empirical data to date detecting the risk factors related to craving and relapse from the perspective of MA abusers. Therefore, the aim of this study was to use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors that could facilitate or impede individuals' abstinence in a real-life context from the perspectives of MA abusers. Aim To use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors relating to individuals' abstinence in a real-life context. Method Semistructured interviews were conducted with 32 MA abusers recruited in Shanghai guided by open-ended questions on narrating the real-life catalysts and inhibitors related to craving, initiation, relapse and abstinence. All data were transcribed verbatim and analysed using a strengths, weaknesses, opportunities and threats (SWOT) analysis. Results The results of the SWOT analysis revealed that contextual factors including peer influence, prevalence and availability of MA, familiar venue of MA use, discrimination, sexual behaviours, alcohol, emotional states and their attitudes towards smoking MA were important factors that contribute to reinitiation and relapse. Surveillance systems, antidrug social workers, vocational skills trainings, moving to another city and family responsibility might serve as counter measures targeti叩 those mentioned weaknesses and threats above. Conclusion This SWOT analysis highlights the complex nature of relapse. Comprehensive interventions strengtheni叩 coping skills such as virtual reality techniques are desperately needed to facilitate individuals1 sustained abstinence.
文摘Objectives:The widespread usage of traditional Chinese medicine(TCM)and the government's emphasis on TCM in China have created a positive macro-environment and great opportunities to develop and strengthen health technology assessment(HTA)in TCM.Over the past ten years,a series of policies have been issued by the government to promote the application of HTA and the development of TCM in China.This study reviews the concepts and characteristics of TCM,summarizes the current status of HTA in TCM,and analyzes the opportunities and challenges faced by HTA development in TCM with respect to deepening of healthcare reforms.Methods:Literature review and website searches were used to acquire information regarding the basic theories of TCM and the current status,opportunities,and challenges for HTA in TCM.Results:The number of articles on HTA in TCM rose substantially,especially those published in China National Knowledge Infrastructure(CNKI).With the optimistic policy environment and huge market demand for TCM,the development of HTA in TCM is expected to flourish in China.However,HTA in TCM also faces numerous challenges such as the absence of a clinical efficacy evaluation system for TCM and insufficient basic research evidence and qualified personnel.Conclusions:TCM has unique characteristic that distinguishes it from Western medicine.Currently,it is important to take all measures to address the existing main challenges and thereby take advantage of the present opportunities to develop and improve HTA in TCM.
文摘Since the People’s Republic of China founded,especially over the last 15 years,maternal mortality rate(MMR)has fallen dramatically.In 2014,China has achieved the target of a reduction of 75%MMR from 1990 to 2015(MDG 5)ahead of schedule.This achievement can be attributed to the improvement of legislation and policy,government commitment and investment on maternal health,extensive international cooperation,implementation of the maternal health program,development of maternal and child health(MCH)service system and development of MCH surveillance systems.Although China has achieved MDG 5,there are many kinds of difficulties and challenges in achieving the post-2015 Sustainable Development Goals(SDGs).Therefore,multi-strategy actions need to be considered to seize the opportunities to further reduce the MMR in the future.
文摘Objectives:Economic growth and rapid development of health technology in China have created opportunities to strengthen health technology assessment (HTA) capacity.Over the time,HTA institutions have been established to conduct HTA related work.This study reviewed the current status of HTA in China and analysed the challenges of HTA development in the context of health reform under'new normal'economy.Methods:Literature review and webpage searches were used to document the development of HTA in China.An institutional survey has also been conducted to collect information on the HTA research institutions in China.Results:The number of articles and research projects on HTA were rising and are continuing to rise.HTA development has made substantial progress in China in terms of growing number of research institutions and qualified HTA workforce.However,HTA has notable weaknesses such as low capacity for conducting HTA research,limited experience in HTA researchers,and lack of knowledge translation.Conclusion:Currently,the translation of HTA findings to policy-making is limited and the integration of HTA in the policy-making processes is still in its infancy.The HTA development in China has had opportunities due to demands of health care,health insurance,and health technology as a result of health reform.Capacity building and institutionalization of HTA are urgently needed for further development of HTA in China.
