Objective
To evaluate the cost effectiveness of four different mechanisms clinical commonly used antidepressants, namely, amitriptyline, escitalopram, mirtazapine and venlafaxine in the treatment of moderate-severe depressive disorder in China and to provide clinicians with some advice.
Methods
We carried out the cost-effectiveness analysis of four antidepressants by establishing a decision tree model. The parameters uncertainty in the model was estimated through one-way sensitivity analysis.
Results
In terms of average cost-effectiveness ratio (CER), amitriptyline’s was 45.24 RMB, which was the lowest. And the CERs of mirtazapine, escitalopram and venlafaxine were 273.71 RMB, 332.00 RMB and 716.58 RMB, respectively. While in terms of incremental cost-effectiveness ratio (ICER), venlafaxine was excluded as the dominated strategy. When the threshold value of willingness to pay (WTP) was less than 3?420.92 RMB, amitriptyline was the most cost-effective; when the threshold value ranges between 3?420.92 RMB and 4?200 RMB, mirtazapine was the most cost-effective; and when the threshold value was over 4?200 RMB, escitalopram was the most cost-effective. In the one-way sensitivity analysis, when we changed the four kinds of drugs costs within a certain range, the results was not changed with the change of venlafaxine’s cost but changed with the other three drugs costs.
Conclusion
Clinicians may choose the most cost-effective therapy according to patients’ different WTP values. We suggests that health care institutions should encourage the use of escitalopram clinically and provide subsidies for patients so as to increase the overall society benefit.
ObjectiveTo systematically review the economics evaluation studies on the early screening or diagnosis of primary immunodeficiency diseases (PID). MethodsWeb of Science, CRD, PubMed, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect the economics evaluation studies on the early screening or diagnosis of PID from inception to July 1st, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, a descriptive systematic review was performed. ResultsA total of 10 studies focusing on SCID were included. The results showed that under a relatively high threshold, the early screening and diagnosis of SCID were cost-effective, which can reduce severe infections in patients and treatment costs while improving patient’s survival. ConclusionCurrent evidence shows that early diagnosis of PID can reduce costs and improve benefits. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.

Objective To compare the economic effectiveness of universal screening, high-risk population screening, and no screening strategies for thyroid disease prevention and control among pregnant women in China through cost-effectiveness analysis, providing evidence-based support for optimizing health policy decisions on prenatal thyroid disease screening. Methods Based on the characteristics of thyroid disorders during pregnancy, a combined decision tree and Markov model was developed to conduct a lifetime cost-effectiveness analysis across three strategies: no screening, high-risk population screening, and universal screening. Sensitivity analyses were performed on key parameters. Results Base-case analysis demonstrated that universal screening was the most cost-effective strategy when the World Health Organization (WHO)-recommended payment threshold of 1×gross domestic product (GDP) per capita was used, with an incremental cost-effectiveness ratio (ICER) of 20636.18 yuan per quality-adjusted life year (QALY) compared to no screening, followed by high-risk population screening (ICER=21071.71 yuan/QALY). The results of the sensitivity analysis showed a strong stability of the model. Conclusions Of the 3 screening programs for thyroid disease in pregnancy, universal screening is the most cost-effective when the WHO-recommended payment threshold of 1×GDP per capita is used.
Objective To evaluate the cost-effectiveness of chemotherapy in children with newly diagnosed Hodgkin lymphoma at low-, intermediate-, and high-risk. Methods From the perspective of health system, a decision-tree model was designed for cost-effectiveness analysis. The chemotherapy regimens of low-risk group included OEPA (vincristine, etoposide, prednisone, doxorubicin), AV-PC (doxorubicin, vincristine, prednisone, cyclophosphamide), and ABVD (doxorubicin, bleomycin, vincristine, dacarbazine); intermediate-risk group included OEPA, ABVE-PC (doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide) and ABVD; high-risk group included OEPA, ABVE-PC, ABVD and BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). The effectiveness and cost parameters were derived from the event-free survival rate reported in the literature, the drug linked reference price in Sichuan province, and treatment price of medical institutions. Univariate and probabilistic sensitivity analysis were performed to explore the impact of uncertainty. Results In the low-risk group, compared with AV-PC, the incremental cost-effectiveness ratios (ICER) of OEPA and ABVD were 80 700 yuan and 108 799 yuan, respectively. In the intermediate-risk group, compared with OEPA, the ICER of ABVE-PC and ABVD were ?17 737 yuan and ?4 701 yuan respectively. In the high-risk group, compared with ABVE-PC, the ICER of OEPA, ABVD and BEACOPP were 149 262, 472 090 and 64 652 yuan, respectively. Univariate sensitivity analysis showed that in low-risk group, the most influential factors were cost of OEPA and cost of ABVD; in moderate-risk group were cost of ABVE-PC and cost of OEPA; in the high-risk group were cost of OEPA, cost of ABVD, and cost of BEACOPP, respectively. The results of probabilistic sensitivity analysis are basically consistent with those of the main analysis. Conclusion If China's per capita gross domestic product in 2023 (89 358 yuan) was used as the willingness-to-pay (WTP) threshold, OEPA in the low-risk group, OEPA in the intermediate-risk group and BEACOPP in the high-risk group are cost-effective.
ObjectiveTo compare the cost-effectiveness between endoscopic retrograde cholangio-pancreatography (ERCP) treatment and laparotomy treatment for simple common bile duct stone or common bile duct stone combined with gallbladder benign lesions.
MethodsA total of 596 patients with common bile stone received ERCP (ERCP group) and 173 received open choledocholithotomy (surgical group) in our hospital between January 2009 and December 2012. Their clinical data were retrospectively analyzed. The curing rate, postoperative complications, hospital stay, preoperational preparation and total cost were compared between the two groups of patients. Meanwhile, for common bile stone combined with gallbladder benign lesion, 29 patients received ERCP combined with laparoscopic cholecystectomy (LC) (ERCP+LC group), 38 received pure laparoscopy treatment (laparoscopy group) and 129 received open choledocholithotomy combined with cholecystectomy (surgery group).
ResultsFor simple common bile stone patients, no significant difference was found in cure rate and post-operative complication between endoscopic and surgical treatment groups (P>0.05). However, total hospitalization expenses[(13.1±6.3) thousand yuan, (20.6±7.5) thousand yuan)], hospital stay[(8.91±4.95), (12.14±5.15) days] and preoperative preparation time[(3.77±3.09), (5.13±3.99) days] were significantly different between the two groups (P<0.05). For patients with common bile stone combined with gallbladder benign lesion, no significant discrepancy was detected among the three groups in curing rate and post-operative complications (P>0.05). Significant differences were detected between ERCP+LC group and surgical group in terms of total hospitalization expense[(18.9±4.6) thousand yuan, (23.2±8.9) thousand yuan] hospital stay[(9.00±3.74), (12.47±4.50) days] and preoperative preparation time[(3.24±1.83), (5.15±2.98) days]. No significant difference was found in total hospitalization expense and hospital stay, while significant difference was detected in preoperative preparation time between ERCP+LC group and simple LC group.
ConclusionFor patients with simple common bile stone, ERCP is equivalent to surgery in the curing rate, and has more advantages such as less cost, shorter length of hospital stay, and lower preoperative preparation time. For the treatment of common bile duct stone with gallbladder benign disease, ERCP combined with LC also has more advantages than traditional surgery.
Objective To evaluate the cost-effectiveness of three LTBI screening strategies: the tuberculin skin test (TST), the T-SPOT.TB and the combination of TST and T-SPOT (TST+T.SPOT), to provide economic evidence for T.SPOT application in China. Methods A decision analysis model evaluated three strategies among a cohort of 1000 tuberculosis (TB) close contacts, using incremental cost-effectiveness of prevention a active TB patient (1 year post contact). Meta analyses were conducted to calculate the key parameters of T.SPOT and TST. The official data or literature was searched and the unaccessible data was to specify other parameters, such as cost, LTBI prevalence, etc. The one-way sensitivity analysis was performed, varying key parameters over a wide range of reasonable values to evaluate the impact of data uncertainties and to determine the robustness of our overall conclusion. Results a) As for the total cost, the TST+T.SPOT strategy (?212 213.81 per 1 000 contacts) cost the least, while the single T.SPOT strategy cost the most; b) Subsequently, the TST+T.SPOT strategy required less contacts to be treated to prevent an active case of TB (8.31) than the single TST strategy (25.67); c) the TST+T.SPOT strategy shared the most cost-effectiveness (?3 063.50 per active TB case prevented) than the single TST or T.SPOT strategy; and d) The results of one-way sensitivity analyses showed that cost-effectiveness values were sensitive to changes in LTBI prevalence (gt;60%), Sen and Spn of TST test (gt;70%), with the single TST being superior to the single T.SPOT. Conclusion The Single T.SPOT strategy enjoys the most cases prevented from active TB, while the TST+S.SPOT strategy is the most cost-effective. The conclusion is sensitive to a few parameters, such as LTBI prevalence, but the TST+T.SPOT strategy is always the best.
ObjectiveTo assess the health effectiveness, cost and cost effectiveness of different oral anticoagulation (OAT) therapies in China, including warfarin plus international normalized ratio (INR) test in hospital labs (Lab test), warfarin plus patient self-management (PSM) with point of care device, and novel anticoagulant (Dabigatran) alone.
MethodsA Markov model containing four states (no complication, hemorrhagic event, thrombotic event and death) was developed to account for long-term cost and outcomes of warfarin/novel anticoagulant users including atrial fibrillation patients and deep venous thrombosis patients. Direct medical cost was taken into consideration, covering expenses of drugs, OAT monitoring and complication management. Both clinical and cost parameters were mainly derived from literatures.
ResultsCompared with hospital lab test, the PSM pattern obtained a prolonged 8.48 years and 5.08 QALYs with the larger amount of cost, CNY 47 482. The incremental cost-effectiveness ratio (ICER) of PSM versus hospital lab test came to CNY 19 240 per QALY gained, lower than GDP China per capita in 2014 (CNY 46 628). And the novel anticoagulant pattern was dominated by PSM pattern due to shortened QALYs while increased cost. The sensitivity analysis demonstrated the results were not sensitive to main indicators, including utility in different health status, complication probability, and disease management cost.
ConclusionPSM can generate more QALYs by reducing the risk of major thrombotic and bleeding events with acceptable incremental cost, which turns to be the most cost effective way among the 3 patterns and demonstrates promising future in OAT management.
