With the development of health technology assessments, the public are increasingly aware of the importance of assessing timeliness for health decision-making, which emerges the requirement for early and timely assessment for emerging health technologies. Providing early and timely assessments prior to a technology accesses the market or prior to implementation can provide decision-makers with sufficient time to develop an application program for a new technology. This paper mainly summarizes the profiles of three emerging health technology horizon scanning systems in Canada, Australia, New Zealand and Sweden, and compares and analyzes their related contents, thus providing reference experience for the construction of emerging health technology horizon scanning system in China.
ObjectivesTo systematically review the health utility scores and disability weights of liver cancer and related diseases in China.MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data, CBM and VIP databases were electronically searched to collect the studies of health utility scores and disability weights of liver cancer and related diseases in China from inception to November, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 9 studies were included which covered 10 related diseases, among which chronic hepatitis B, compensated cirrhosis, decompensated cirrhosis and liver cancer were the mostly reported. The overall quality was adequate, and EQ-5D was the most common tool in these studies. Results of meta-analysis showed that healthy utility scores of the four common diseases were 0.789 (0.735, 0.843), 0.734 (0.693, 0.776), 0.647 (0.627, 0.666) and 0.636 (0.508, 0.765), respectively. Measures from EQ-5D were 0.825 (0.762, 0.868), 0.761 (0.731, 0.791), 0.643 (0.620, 0.666) and 0.620 (0.473, 0.766), respectively. In addition, the corresponding median (range) utility scores of the four diseases were found to be 0.758 (0.520–0.950), 0.716 (0.570–0.900), 0.538 (0.260–0.662) and 0.541(0.310–0.720). Only one disability weight study was concluded (0.360–0.900 reported for liver cancer).ConclusionIn Chinese population, current evidences on health utility of liver cancer and related diseases are limited, particularly data on disability weights. Utility values from meta-analysis seems more optimistic and centralized than those from descriptive analysis. Different survey tools yield varying outcomes, and attentions should be addressed to their application. The decrease of heath utility scores with the severity of liver disease suggests that early prevention, early diagnosis and treatment can save more years of life with enhanced quality.
ObjectivesTo estimate the latest burden of disability adjusted life years (DALYs) for liver cancer in China and the long-term trend, and to make future prediction.MethodsBased on the visualization platform of Global Burden of Disease 2016, data on the DALYs for liver cancer in China was extracted. The very recent status in 2016 and the previous trend from 1990 to 2016 were described, using annualized rate of change (ARC). The burden from 2017 to 2050 was further predicted by combining the ARC and the Chinese population data projected by the United Nation.ResultsIn 2016, the total DALYs for liver cancer in China was estimated as 11 539 000 person years (accounting for 54.6% of the global burden), and years of life lost (YLLs) and years lived with disability (YLDs) contributed 98.9% and 1.1%, respectively. The age-standardized DALY rate was 844.1 per 100 000 (3.0 times of the global average) and the male-to-female ratio was 3.4. The DALY rate continuously increased from 1990–2016 (ARC=0.57%), particularly in recent 5 years (ARC=1.75%). Among the DALYs for all cancers, liver cancer contributed approximately 20% and constantly remained as the top 2 (ranking as the number one before year 2005). There were inverse trends in gender, with increasing in males and decreasing in females (ARC was 0.77% and –0.11%, respectively). Hepatitis B infection continually kept the leading cause of DALYs for liver cancer (accounting for nearly 57%), and the DALY rate was gradually increasing (ARC=0.43%). Although the peak age of DALY rate was stable at 65to 69 years, the peak age of the DALYs changed from 55 to 59 years in 1990 to 60 ~ 64 years in 2016. In 2050, the estimated DALYs for liver cancer in China will reach 14.37 million person years, 20.0% more than that in 2017.ConclusionsThe DALYs caused by liver cancer in China exceeds the overall burden of all other countries in the world, and accounts for 1/5 of DALYs for all cancers in local population. The burden in males has been continuously rising, and the leading cause remained unchanged as hepatitis B infection. With population aging, the DALYs for liver cancer in China will be incessant to increase, suggesting the necessity to implement continuous effort in risk factors prevention (e.g. hepatitis B infection), and efficient management in high risk population of liver cancer.
