Cost-effectiveness analysis of treatments for metastatic castration resistant prostate cancer

Objective:Treatment options for metastatic castration resistant prostate cancer(mCRPC)have expanded rapidly in recent years.Given the significant economic burden,we sought perform a cost-effectiveness analysis(CEA)of the contemporary treatment paradigm for mCRPC.Methods:We devised a treatment protocol consisting of sipuleucel-T,enzalutamide,abiraterone,docetaxel,radium-223,and cabazitaxel.We estimated number and length of treatments for each therapy using dosing schedules or progression free survival data from published clinical trials.We estimated treatment cost using billing data and Medicare reimbursement values and performed a CEA.Our analysis assumed US$100,000 per life year saved(LYS)as the threshold societal willingness to pay.Results:Incremental cost-effectiveness ratios(ICER)for strategies incorporating sipuleucel-T that were not eliminated by extended dominance exceeded the societal threshold willingnessto-pay of US$100,000 per LYS,the lowest of which was sipuleucel-T+enzalutamide+abiraterone+docetaxel at US$207,714 per LYS.Enzalutamide+abiraterone+docetaxel exhibited the most favorable ICER among strategies without sipuleucel-T at US$165,460 per LYS.Conclusion:Based on the available survival data and current costs of treatment,all treatment strategies greatly exceed a commonly assumed societal willingness-to-pay threshold of US$100,000 per LYS.Improvements in this regard can only comewith a reduction in pricing,better tailoring of treatment or significant enhancements in survival with clinical use of treatment combinations or sequences.

Cost of postoperative complications:How to avoid calculation errors

Postoperative complications(PC)are a basic health outcome,but no surgery service in the world records and/or audits the PC associated with all the surgical procedures it performs.Most studies that have assessed the cost of PC suffer from poor quality and a lack of transparency and consistency.The payment system in place often rewards the volume of services provided rather than the quality of patients’clinical outcomes.Without a thorough registration of PC,the economic costs involved cannot be determined.An accurate,reliable appraisal would help identify areas for investment in order to reduce the incidence of PC,improve surgical results,and bring down the economic costs.This article describes how to quantify and classify PC using the Clavien-Dindo classification and the comprehensive complication index,discusses the perspectives from which economic evaluations are performed and the minimum postoperative follow-up established,and makes various recommendations.The availability of accurate and impartially audited data on PC will help reduce their incidence and bring down costs.Patients,the health authorities,and society as a whole are sure to benefit.

Fractional Flow Reserve Guided Percutaneous Coronary ntervention Improves Clinical Outcome with Reduced Cost in Contemporary Clinical Practice

Background：Fractional flow reserve （FFR） is currently considered as the gold standard for evaluating the functional significance of coronary stenosis.However,its potential benefits in real-world practice remain unknown in China.This study aimed to test the hypothesis that the use of FFR is associated with improved outcome and reduced cost in Chinese real-world clinical practice.Methods：A retrospective cohort study was carried out using the database of Second Affiliated Hospital of Zhejiang University,a tertiary and high-volume center in China.Clinical events were compared using the Cox proportional hazards model during a median follow-up of 13 months.Results：The study cohort consisted of 366 consecutive patients referred for coronary revascularization with adjunct FFR and 366 matched controls,from 2010 to 2014.Major adverse cardiac events （MACEs） （death,myocardial infarction,repeated revascularization,or hospitalization for angina） at 4 years were found in 12.0% ofangiography-guided patients and 4.9% in the FFR-guided group （P 〈 0.001）.The mean number of implanted stents was significantly lower in FFR treated subjects （0.52 ± 0.82 stents） compared with the angiography-guided group （0.93 ± 0.96 stents） （P 〈 0.001）.No difference in overall costs at initial hospitalization was observed between angiography-guided percutaneous coronary intervention （PCI） compared with FFR-guided PCI （RMB 33,000 Yuan,range：RMB 7393-44,700 Yuan） versus RMB 21,200 Yuan （RMB 19,100-47,100 Yuan） （P =0.54）.However,costs for MACEs during follow-up were significantly reduced in the FFR-guided arm （P 〈 0.001）.Conclusions：In the contemporary clinical practice,FFR-guided PCI is associated with decreased use of stents,improved clinical outcome,and reduced costs,compared with angiography-guided PCI.

Economic evaluations in gastroenterology in Brazil: A systematic review

AIM: To systematically review economic evaluations in gastroenterology, relating to Brazil, published between 1980 and 2013. METHODS: We selected full and partial economic evaluations from among those retrieved by searching the following databases: MEDLINE(PubM ed); Excerpta Medica; the Latin American and Caribbean Health Sciences Literature database; the Scientific Electronic Library Online; the database of the Centre for Reviews and Dissemination; the National Health Service(NHS) Economic Evaluation Database; the NHS Health Technology Assessment database; the Health Economics database of the Brazilian Virtual Library of Health; Scopus; Web of Science; and the Brazilian Network for the Evaluation of Health Technologies. Two researchers, working independently, selected the studies and extracted the data. RESULTS: We ide nt if ie d 535 he alt h e c onomic evaluations relating to Brazil and published in the 1980-2013 period. Of those 535 articles, only 40 dealt with gastroenterology. Full and partial economic evaluations respectively accounted for 23(57.5%) and 17(42.5%) of the 40 studies included. Among the 23 full economic evaluations, there were 11 cost-utility analyses, seven cost-effectiveness analyses, four costconsequence analyses, and one cost-minimization analysis. Of the 40 studies, 25(62.5%) evaluated medications; 7(17.5%) evaluated procedures; and 3(7.5%) evaluated equipment. Most(55%) of the studies were related to viral hepatitis, and most(63.4%) were published after 2010. Other topics included gastrointestinal cancer, liver transplantation, digestive diseases and hernias. Over the 33-year period examined, the number of such economic evaluations relating to Brazil, especially of those evaluating medications for the treatment of hepatitis, increased considerably. CONCLUSION: Further studies are needed in order to ensure that expenditures on health care in Brazil are made as fairly and efficiently as possible.
