  • Basic Theory and Methods and Application of Onehealth Software for Evidence-based Decision-making

    Onehealth, an evidence-based decision-making software, is based on the United Nations' epidemiological reference modules to predict the effect of health services. Onehealth is a large database. The software is using activitybased costing, simulating investment costs of health system and changes of mortality in different coverage levels. By the cost of inputs/avoid deaths, it could quantify the cost of health services effectiveness and provide an intuitive basis for the rational allocation of health resources. This study introduces the relevant concepts, model structures and applications of Onehealth. We took the study of child nutrition interventions in Sudan for example and to present Onehealth tool's operating. As a new auxiliary and evidence-based decision-making software with scientific and rigorous theoretical approach, Onehealth has practical significance on the national or regional macro decision-making.

  • Helical Tomotherapy for Cancer Treatment: A Rapid Health Technology AssessmentΔ

    ObjectiveTo rapidly review the effectiveness, safety, costs and applicability of helical tomotherapy (HT), so as to provide currently-available best evidence for decision makers of government health policies. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP, CBM and other relevant professional websites. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, assessed quality, and then performed descriptive analysis. Resultsa) We finally included 150 studies, encompassing 5 health technology assessments (HTAs), 18 clinical controlled trials (CCTs), and 127 observational studies. b) Four included HTAs were published during 2006-2009, providing fairly less evidence of low quality and the results of 145 primary studies showed that:HT was mainly used in the treatments of 14 types of cancer, with relatively low total toxicity and high survival rates. Although the quality of the included studies was poor, there was much evidence about prostate cancer, head and neck cancer, nasopharynx cancer, cervical cancer, lung cancer and liver cancer, with accumulatively enough sample size and fairly reliable results in HT's efficacy and safety. And c) a total of 56 clinical trials had bee registered in Clinicaltrials.gov, most of which were registered by the occident; among them, 9 had been come to the end, yet without results published. ConclusionCurrent evidence of this study showed that, HT is safe and effective in clinic. But the abovementioned conclusion needs to be verified by conducting more high quality studies with long-term follow-up. The costs of HT in procurement, maintenance and application are high; and the skills, training and qualification of operators are required. We suggest that the procurement of HT should be reduced; it should be allocated rationally and effectively used after comprehensive assessment in China's cancer epidemiology characteristics, health resource allocation, disease burden, medical service level, etc.; and also high quality studies with long-term follow-up should be financially supported on the basis of establishing projects, so as to provide local evidence and consistently guide and improve scientific decision making.
