Objective From the viewpoint of health economics, to analyse the cost-utility of Coflex interspinous dynamic reconstruction and 360° fusion in the treatment of single level lumbar degenerative disease, so as to provide references to doctors and patients for making the best solution. Methods From October 2008 to November 2010, a prospective non-randomized controlled study was carried out on the patients diagnosed as L4-L5 degenerative lumbar spinal disorders, of whom Group A were treated by posterior decompression combined with Coflex interspinous dynamic reconstruction and Group B accepted lumbar 360° fusion treatment. The SF-36 questionnaire was used to survey the life quality of patients and to calculate the quality-adjusted life year (QALY); meanwhile, the costs of the treatment were collected to compare the cost-utility ratio between the two groups. Results A total of 60 patients were included, among whom 29 patients including 20 males and 9 females were in Group A, and the other 31 patients including 16 males and 15 females were in Group B; and the mean time of follow-up was 16.4 months (12-23 months). The average age of Group A and Group B was 45.1 years (21-67 years) and 56.2 years (32-86 years), respectively; the medical costs were 51 509.9±2 422.9 yuan and 57 409.7±9 072.9 yuan, respectively; the life quality compared with that of pre-operation improved by 42.60% and 42.82%, respectively; the cost-utility ratios were 69165.6±4716.0 yuan/QALY and 77 976.7±12 757.4 yuan/QALY, respectively. For each increase of one QALY, Group A could save 12.74% of the cost compared with Group B. Conclusion Coflex interspinous dynamic reconstruction has the equal short-term effects to lumbar 360° fusion in the treatment of L4-L5 degenerative lumbar spinal disorders, but it has lower costs than the latter, and is more in line with the requirements of health economics.
Objective To assess the cost-utility study of renal transplantation compared with nemodialysis (HD) and peritoneal dialysis (PD). Methods A prospective study of end-stage renal disease patients was followed up for 3 months after renal replacement therapy. The study population included 196 patients (renal transplant [RT] n=63, hemodialysis [HD] n=82 and continious ambulatory peritoneal dialysis [CAPD] n=51) from 6 hospitals of Sichuan province. Health-related quality of life was assessed by using the WHOQOL-BRIEF questionnaire. Utility scores were obtained so as to conduct CUA (cost-utility analysis). Costs were collected from financial department and by patient interview. Results The utility values were 0.539 9± 0.013 for RT, 0.450 8± 0.014 for HD, 0.512 2±0.099 for CAPD, respectively. The mean direct cost of the first three months of renal transplant was significantly higher than dialysis (RT and CAPD). Over 3 months, the average cost per quality-adjusted life year (QALY) for patients after CAPD was lower than HD and RT. Compared to HD, incremental cost analysis showed that CAPD was more ecnomical than RT. Sensitive analysis showed that CAPD was more effective than RT when ΔQALY varied in the limit of 95% confidence interval. However, the cost-utility of RT vs HD and CAPD vs HD was varied with ΔQALY level. Conclusions Cost-utility analysis showed that CAPD was a more favorable cost-utility ratio when compared to RT at early stage RT vs HD and CAPD vs HD, but which cost-utility ratio is better, we can not draw a certain conclusion.
Objective To systematically review the health state utility values in patients with schizophrenia, and to provide references for subsequent studies on the health economics of schizophrenia. Methods The PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were searched from inception to December 1st, 2021 to collect studies on health state utility values in patients with schizophrenia. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed by Stata 15.0 software. Results A total of 19 studies were included. Patients’ utility values were 0.68 (95%CI 0.59 to 0.77) for direct measures, and 0.77 (95%CI 0.75 to 0.80) and 0.66 (95%CI 0.61 to 0.70) for indirect measures with the EQ-5D-5L and EQ-5D-3L as the primary scales. Utility values varied with measures, tariffs, regions, and populations. Conclusion Studies on health state utility value in schizophrenia are diversified in measurement methods, showing high inter-study heterogeneity. Therefore, it is necessary to promote the study on utility value measurement in schizophrenia in China.
ObjectivesTo evaluate the economic efficacy of nab-paclitaxel (NAB-P) combined with gemcitabine (GEM) versus GEM alone in the treatment of metastatic pancreatic cancer in China.MethodsA Markov model simulating the costs and health outcomes was developed to estimate quality-adjusted life years (QALYs) and incremental cost-effectiveness ratio (ICER). The impact of parameter uncertainty on the model was assessed by deterministic one-way sensitivity analysis.ResultsNAB-P combined with GEM was shown superior efficacy compared to gemcitabine monotherapy, however with higher costs. The ICER between the two groups was 964 780.79￥/QALY.ConclusionsCompared with gemcitabine monotherapy, NAB-P combined with GEM is not cost-effective. The conclusion is confirmed by deterministic one-way sensitivity analysis.
The multi-attribute utility function (MAUF) is a commonly used method for measuring health utility, characterized by a solid theoretical foundation and operational feasibility. It contributes to reducing the cognitive burden on respondents, caters to the measurement of utility across multiple dimensions, and represents another most widely applied approach beyond traditional econometrics, warranting exploration and application. However, there is currently a lack of comprehensive and systematic research on this method in China, with insufficient practical application experience. Against this backdrop, this paper aims to systematically explore the methodological background of MAUF and the key points of research design for measuring health utility using this method. By drawing on the utility measurement experiences from internationally developed measurement scales such as HUI 1, HUI 2, HUI 3, 15D, AQol-8D, ASUI, HUG-5, TOOL, and ALSUI, it systematically analyzes the critical steps in the practical implementation of the method. It is hoped that this work will comprehensively and clearly elaborate on the practical approaches of MAUF, promote the further development of MAUF in China, and provide methodological references for future studies on health utility measurement based on MAUF.
The discrete choice experiment (DCE) is a stated preference analysis method used to evaluate the impact of multiple factors on individual choice, which has been explored by scholars around the world for health utility measurement. This method is considered to reduce the cognitive burden of traditional utility measurement methods and has high development potential. By examining empirical studies conducted domestically and internationally that employ DCE for measuring health utility, and drawing on methodological guidelines for constructing DCE models, this paper provides an overview of the methodological background of DCE, the practical process used for measuring health utility, and discusses relevant challenges in its application.
Objective To compare the long-term cost-utility of three first-generation EGFR-TKIs targeted drugs, gefitinib, icotinib, and erlotinib as first-line treatments for advanced non-small cell lung cancer (NSCLC). Methods Real-world data were collected from 1 511 patients with advanced NSCLC treated with first-generation EGFR-TKIs as first-line treatment at West China Hospital of Sichuan University from 2009 to 2019. A three-state Markov model was established to evaluate the clinical efficacy, safety and cost-utility of three first-generation EGFR-TKIs targeted drugs. The transition probability of each state was obtained by survival analysis, the direct and indirect costs were calculated by the bottom-up method, the health utility value was obtained through literature research, the incremental cost effectiveness ratio (ICER) and quality-adjusted life years (QALYs) were calculated, and sensitivity analyses and Monte Carlo simulations were performed. Results There was no significant difference in clinical efficacy among the three first-generation EGFR-TKIs in the treatment of NSCLC. The incidence of skin rash and liver injury caused by gefitinib was significantly higher than that caused by icotinib and erlotinib (P<0.05). The average economic burden of patients treated with icotinib was the lowest (CNY 192 535.3) (P<0.01). The cost-utility ratio of icotinib (CNY 132 985.9/QALYs) was much lower than that of gefitinib (CNY 205 005.3/QALYs) and erlotinib (CNY 172 893.1/QALYs). Conclusion Compared with the three first-generation EGFR-TKIs drugs, icotinib is the most cost-effective.
ObjectiveTo evaluate the effect of health economics of census versus high-risk population screening for tuberculosis in Mianyan city, in order to provide references for the selection of suitable tuberculosis screening method in western region of China. MethodsWe included active tuberculosis patients by residents health screening of 21 villages and towns in Mianyan city from June 2013 to March 2013. Relevant data was analyzed by referencing the National Assessment of Tuberculosis Control Program in 2001-2010. Results184047 residents were screened by tuberculosis census and 128 active tuberculosis patients were diagnosed while 61045 residents were screened by high-risk population screening and 76 active tuberculosis patients were diagnosed. The cost-utility ratio and benefit-cost ratio of tuberculosis census were 6174.17 and 3.84, respectively. The cost-utility ratio and benefit-cost ratio of high risk population screening were 3106.16 and 7.62, respectively. ConclusionHigh-risk population screening has higher cost-utility ratio and benefit-cost ratio than tuberculosis census with higher missed diagnosis. Benefits and harms of tuberculosis detection rate and cost should be fully balanced before tuberculosis screening method were chosen in western underdeveloped region of 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.
