Additional MRI for initial M-staging in pancreatic cancer: a cost-effectiveness analysis

Abstract Objective Pancreatic cancer is portrayed to become the second leading cause of cancer-related death within the next years. Potentially complicating surgical resection emphasizes the importance of an accurate TNM classification. In particular, the failure to detect features for non-resectability has profound consequences on patient outcomes and economic costs due to incorrect indication for resection. In the detection of liver metastases, contrast-enhanced MRI showed high sensitivity and specificity; however, the cost-effectiveness compared to the standard of care imaging remains unclear. The aim of this study was to analyze whether additional MRI of the liver is a cost-effective approach compared to routinely acquired contrast-enhanced computed tomography (CE-CT) in the initial staging of pancreatic cancer. Methods A decision model based on Markov simulation was developed to estimate the quality-adjusted life-years (QALYs) and lifetime costs of the diagnostic modalities. Model input parameters were assessed based on evidence from recent literature. The willingness-to-pay (WTP) was set to $100,000/QALY. To evaluate model uncertainty, deterministic and probabilistic sensitivity analyses were performed. Results In the base-case analysis, the model yielded a total cost of $185,597 and an effectiveness of 2.347 QALYs for CE-MR/CT and $187,601 and 2.337 QALYs for CE-CT respectively. With a net monetary benefit (NMB) of $49,133, CE-MR/CT is shown to be dominant over CE-CT with a NMB of $46,117. Deterministic and probabilistic survival analysis showed model robustness for varying input parameters. Conclusion Based on our results, combined CE-MR/CT can be regarded as a cost-effective imaging strategy for the staging of pancreatic cancer. Key Points • Additional MRI of the liver for initial staging of pancreatic cancer results in lower total costs and higher effectiveness. • The economic model showed high robustness for varying input parameters.

BACKGROUND Mobile health (mhealth) technology is increasingly used in disease management. Using mhealth tools to integrate and streamline care was found to improve atrial fibrillation (AF) patients’ clinical outcomes. OBJECTIVE This study aimed to investigate the potential clinical and health economic outcomes of mhealth-based integrated care for AF from the perspective of a public healthcare provider in China. METHODS A Markov model was designed to compare outcomes of mhealth-based care and usual care in a hypothetical cohort of AF patients in China. The time horizon was 30 years with monthly cycles. Model outcomes measured were direct medical cost, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). Sensitivity analyses were conducted to examine the robustness of base-case results. RESULTS In the base-case analysis, mhealth-based care gained higher QALYs of 0.0818 with an incurred cost of USD1,778. Using USD33,438 per QALY (three times gross domestic product) as the willingness-to-pay threshold, mhealth-based care was cost-effective, with an ICER of USD21,739 per QALY. The one-way sensitivity analysis found compliance to mhealth-based care had the greatest impact on the ICER. In probabilistic sensitivity analysis, mhealth-based care was accepted as cost-effective in 80.91% of 10,000 iterations. CONCLUSIONS This study suggested that the use of mhealth technology in streamlining and integrating care for AF patients was cost-effective in China.

The Impact

This study evaluated the cost-effectiveness of the consumption of a milk powder product fortified with potassium (+1050.28 mg/day) and phytosterols (+1200 mg/day) to lower systolic blood pressure and low-density lipoprotein cholesterol, respectively, and, therefore, the risk of myocardial infarction (MI) and stroke among the 35–75-year-old population in Malaysia. A Markov model was created against a do-nothing option, from a governmental perspective, and with a time horizon of 40 years. Different data sources, encompassing clinical studies, practice guidelines, grey literature, and statistical yearbooks, were used. Sensitivity analyses were performed to evaluate the impact of uncertainty on the base case estimates. With an incremental cost-effectiveness ratio equal to international dollars (int$) 22,518.03 per quality-adjusted life-years gained, the intervention can be classified as very cost-effective. If adopted nationwide, it would help prevent at least 13,400 MIs, 30,500 strokes, and more than 10,600 and 17,100 MI- and stroke-related deaths. The discounted cost savings generated for the health care system by those who consume the fortified milk powder would amount to int$8.1 per person, corresponding to 0.7% of the total yearly health expenditure per capita. Sensitivity analyses confirmed the robustness of the results. Together with other preventive interventions, the consumption of milk powder fortified with potassium and phytosterols represents a cost-effective strategy to attenuate the rapid increase in cardiovascular burden in Malaysia.

Abstract BACKGROUND The addition of novel therapy “Tumor-Treating fields” (TTF) to standard radio-chemotherapy with Temozolomide (TMZ) has recently shown superiority over conventional TMZ regimen in patients with glioblastoma. Despite the clinical benefit of TTF, there is a strong concern regarding the cost of this new treatment. A first cost-effectiveness analysis, which was published in 2016, was based on effectiveness outcomes from an interim analysis of the pivotal trial and used a “standard” Markov model. Here, we aimed to update the cost-effectiveness evaluation using a partitioned survival model design and using the latest effectiveness data. MATERIAL AND METHODS A partitioned survival model was developed with three mutually exclusive health states: stable disease, progressive disease, and dead. Parametric models were fitted to the Kaplan-Meier data for overall and progression-free survival. These generated clinically plausible extrapolations beyond the observed data. The perspective of the French national health insurance was adopted and the time horizon was 20 years. Base case results were expressed as cost/life-years (LY) gained (LYG). Secondary analyses were undertaken, with the results presented as cost/per quality adjusted life years (QALY) gained. Last, we undertook deterministic and probabilistic sensitivity analyses. RESULTS After applying 4% annual discounting of benefits and costs, the base case model generated incremental benefit of 0.507 LY at a incremental cost of €258,695 yielding an incremental cost effectiveness ratio (ICER) of €510,273 / LYG. Secondary analyses yielded an ICER of €667,173/QALY. Sensitivity analyses and bootstrapping methods showed the model was relatively robust. The model was sensitive to TTF device costs and the parametric model fitted to the Kaplan-Meier data for overall survival. The cost-effectiveness acceptability curve showed TTF has 0% of being cost-effective under conventional thresholds. CONCLUSION Using a partitioned survival model, uprated costs and more mature survival outcomes, TTF when compared to standard radio-chemotherapy with TMZ is not likely to be cost-effective. This has major implications in terms of access of newly eligible patients

Meta Analyses

Introduction:Stereo-electroencephalography (SEEG) has been shown to be a valuable tool for the anatomo-electroclinic definition of the epileptogenic zone (EZ) in some patients with medically refractory epilepsy considered for surgery. In Spain, many of those patients are not offered this diagnostic procedure. The objective of our health technology assessment (HTA) report was to evaluate the effectiveness, safety and cost-effectiveness of SEEG to define the EZ in patients with refractory epilepsy considered for surgery compared to no SEEG intervention (i.e. remaining with further antiepileptic drugs).Methods:We undertook a systematic review with meta-analyses on the effectiveness and safety of SEEG. A cost-effectiveness analysis was conducted using a Markov model which simulates the costs and health outcomes of individuals for a lifetime horizon from the perspective of the Spanish National Health Service (NHS). The effectiveness measure was quality-adjusted life years (QALYs). We ran extensive sensitivity analyses, including a probabilistic sensitivity analysis.Results:The EZ was found in 92 percent of patients who underwent SEEG, 72 percent were eligible for epilepsy surgery and 33 percent were free of seizures after surgery (47 percent of those who received surgery). Any complications related to insertion and monitoring of SEEG and the subsequent intervention occurred in 1.3 percent of patients. In the base case analysis, SEEG led to higher QALYs and healthcare costs with an estimated incremental cost-effectiveness ratio of EUR 10,368 (USD 12,217) per QALY. The sensitivity analyses showed that the results of the study were robust.Conclusions:SEEG is a cost-effective technology in patients with refractory epilepsy considered for surgery when compared to no SEEG intervention.

Pediatric Heart Transplantation

Introduction: Allosensitized children listed with a requirement for a negative prospective crossmatch (XM) have a high risk of death awaiting heart transplantation (HTx). Previously we found that acceptance of the first suitable organ offer for these patients, regardless of the possibility of a +XM, results in a survival benefit at all times after listing, including post-HTx. The cost-effectiveness of this strategy is unknown. Methods: We used a Markov-state transition model with a 10 yr time horizon to compare survival, costs, and utility (i.e. quality of life) for 2 waitlist strategies for sensitized candidates: requiring a negative prospective XM (WAIT) vs. accepting the first suitable organ offer (TAKE). Model data were derived from OPTN status 1A pediatric HTx listings from 1999-2009, the PHTS and HCUP KIDS databases, and other published sources. We assumed no possibility of a +XM in the wait strategy and that the probability of a +XM in the take strategy was equal to the pre-transplant PRA. Results: At base case, TAKE was dominant; it cost less ($122,856) and gained more (1.04) quality-adjusted life-years (QALYs) than WAIT. In sensitivity analyses varying all model parameters individually over clinically plausible ranges, TAKE remained dominant or favored (using a $100,000/QALY cost-effectiveness threshold) except when the probability of HTx for TAKE was <55% over 2 years (base case value 67%). After adjustment of the model so that waitlist probabilities of death and delisting were equal in both strategies (while maintaining the lower probability of HTx associated with WAIT), TAKE remained dominant. WAIT was no longer dominated if mortality after HTx across a +XM was >30%/year (equivalent to median post-HTx survival of <3 yrs); yet even at the extreme assumption of 100% 1-year mortality after HTx across a +XM for TAKE, the wait strategy was not cost effective ($350,097/QALY). CONCLUSIONS: Among sensitized status 1A pediatric HTx candidates, we found that taking the first suitable organ offer is less costly and results in greater survival than awaiting HTx across a negative prospective XM. This suggests that HTx should not be denied based on sensitization status alone.

Background: Contrast-induced acute kidney injury (CI-AKI) is defined as a deterioration in renal function after administration of radiologic iodinated contrast media (CM). Iodixanol, showed a lower CI-AKI incidence than low-osmolar contrast media (LOCM). A cost-effectiveness analysis was performed comparing iodixanol and LOCM in intravenous (IV) setting in Italy.Methods: A Markov model was developed. Patients moved across four health states: CI-AKI free, CI-AKI, myocardial infarction, and death. The simulation horizon was lifetime with 1-month cycles. Costs and outcomes were discounted at 3.5 percent rate. CI-AKI incidence was considered from published literature across different definitions. Cost-effectiveness of iodixanol was assessed in terms of incremental cost per life-year gained. Net monetary benefit (NMB) was also calculated. Both deterministic and probabilistic sensitivity analyses were performed.Results: Base-case results showed an average survival increase of 0.51 life-years and a savings of €7.25 for iodixanol versus LOCM. The cost-effectiveness of iodixanol was confirmed when other scenarios were explored, such as varying CI-AKI definition, sub-populations with specified risk factors, CM hospital bids prices, and inclusion of adverse drug reactions of allergic nature. An NMB ranging between €6,007.25 and €30,007.25 was calculated.Conclusion: Base-case results show that IV iodixanol is cost-effective compared with LOCM in the Italian clinical setting of a hospital computed tomography radiology practice. However, some caution is due, mainly linked to inherent limitations of the modeling technique and to the lack of agreement on CI-AKI incidence data in the clinical literature.

Background: Glioblastoma multiforme (GBM) is a fatal type of brain tumor with a high incidence among elderly people. Temozolomide (TMZ) has proven to be an effective chemotherapeutic agent with significant survival benefits. This study aimed to evaluate the economic outcomes of radiotherapy (RT) and TMZ for the treatment of newly diagnosed GBM in elderly people in the United States (US) and China.Methods: A partitioned survival model was constructed for RT plus TMZ and RT alone among patients with methylated and unmethylated tumor status. Base case calculations and one-way and probabilistic sensitivity analyses were performed. Life-years, quality-adjusted life-years (QALYs), costs (in 2021 US dollars [$] and Chinese Yuan Renminbi [¥]), and incremental cost-effectiveness ratios (ICERs) were calculated.Results: RT plus TMZ was found to be associated with significantly higher costs and QALYs in all groups. Only US patients with methylated status receiving RT plus TMZ had an ICER ($89358.51) less than the willingness-to-pay (WTP) threshold of $100000 per QALY gained when compared with receiving RT alone. When the WTP threshold ranged from $100000 to $150000 from the US perspective, the probability of RT plus TMZ being cost-effective increased from 80.5 to 99.8%. The cost of TMZ must be lower than ¥120 per 20 mg for RT plus TMZ to be cost-effective among patients with methylated tumor status in China.Conclusion: RT plus TMZ was not cost-effective in China, and a reduction in the TMZ price was justified. However, it is highly likely to be cost-effective for patients with methylated tumor status in the US.

Background: End-stage renal disease has been imposing a heavy economic burden on public health; however, few studies have been performed on the cost-effectiveness of dialysis modalities. We aim to estimate the cost-effectiveness of different dialysis modalities in China. Methods: Cost-effectiveness analyses were performed using Markov models based on published data of hemodialysis (HD) and peritoneal dialysis (PD) modalities in China. Sensitivity analyses were conducted to identify key variables influencing the results. Results: Over a 10-year time horizon, the base-case cost-effectiveness analysis indicated that PD-first absolutely dominated the HD-first option by gaining 0.13 more quality-adjusted life years (QALYs) and costing RMB ¥81,081 less. When using reported mortality of HD and PD from the United States, the PD-first option still dominated HD-first with higher QALYs and lower costs. Sensitivity analyses revealed that the results were more sensitive to the direct cost of HD, utility of HD, utility of PD, direct cost of PD, PD mortality, and HD mortality, while less sensitive to the indirect costs and transition probabilities. The HD utility needed to be at least 0.148 higher than PD utility for HD to be cost-effective. PD was about 72% likely to be considered cost-effective compared with HD, regardless of the willingness-to-pay for QALYs. Conclusion: PD appears to be more cost-effective than HD in China, and the major influential factors on the cost-effectiveness are the direct costs of HD, utility of HD, utility of PD, direct costs of PD, PD mortality, and HD mortality.

Abstract Background Adolescent depression has negative health and economic outcomes in the short- and long-term. Indicated preventive interventions, in particular group based cognitive behavioural therapy (GB-CBT), are effective in preventing depression in adolescents with subsyndromal depression. However, little is known about the cost-effectiveness of these interventions. Methods A Markov cohort model was used to conduct cost-effectiveness analyses comparing a GB-CBT indicated preventive intervention for depression, to a no-intervention option. Taking a time horizon of 5- and 10 years, incremental differences in societal costs and health benefits expressed as cases of depression prevented, and as quality adjusted life years (QALYs) gained were estimated. Through univariate and probabilistic sensitivity analyses, the robustness of the results was explored. Costs, presented in 2018 USD, and effects were discounted at a yearly rate of 3%. Results The base-case analysis showed that GB-CBT indicated preventive intervention incurred lower costs, prevented more cases of depression and generated higher QALYs compared to the no-intervention option for both time horizons. Offering the intervention was even a cost saving strategy and demonstrated a probability of being cost-effective of over 95%. In the sensitivity analyses, these results were robust to the modelling assumptions. Limitations: The study considered a homogeneous cohort and assumed a constant annual decay rate of the relative treatment effect. Conclusions GB-CBT indicated preventive interventions for depression in adolescence can generate good value for money compared to leaving adolescents with subsyndromal depression untreated. Key messages Indicated preventive interventions for depression are cost-saving and can generate substantial health benefits. Indicated preventive interventions can be adopted as cost-effective preventive strategies for depression.

e17569 Background: FOLFIRINOX has been shown to be superior to gemcitabine (gem) alone for metastatic pancreatic cancer (MPC) and has been established as the standard of care. A recent study (von Hoff et al, GI ASCO 2013) showed that gem + nab-paclitaxel (gem+nab-p) was superior to gem alone. The cost-effectiveness of gem+nab-p relative to gem or FOLFIRINOX has not been studied. Methods: A Markov cohort model was constructed for patients with MPC to examine the costs and outcomes of gem alone, gem+nab-p and FOLFIRINOX. Efficacy and side-effect data were obtained from pivotal phase III trials. Resource utilization data, unit costs and utilities were obtained from Ontario Ministry of Health and Long-Term Care, Sunnybrook Health Sciences Centre and the literature. The primary outcome was the incremental cost-effectiveness ratio (ICER) defined as cost per quality-adjusted life year (QALY). The analysis was conducted from the perspective of the Canadian public healthcare system over a 2-year time horizon adjusted to 2012 Canadian dollars (CAD$). Both cost and effectiveness were discounted at 5%. One way and probabilistic sensitivity analyses were performed. Results: Using gem as the base case, gem+nab-p had better outcomes but higher costs (see Table). The ICER was higher than conventional willingness-to-pay (WTP) threshold. Gem+nab-p was less effective but less costly when compared with FOLFIRINOX. It was dominated by combinations of gem and FOLFIRINOX (i.e. extended dominance), and therefore not cost-effective regardless of WTP threshold. If the price of nab-p was 20% lower, then gem+nab-p and FOLFORINOX would have similar cost-effectiveness. Conclusions: Gem+nab-p is not cost-effective, from the Canadian perspective, for the treatment of MPC based on the current price when compared with FOLFIRINOX. A lower-priced generic oxaliplatin, which is available in some jurisdictions including the United States, may affect the outcome of this analysis in further favor of FOLFIRINOX. [Table: see text]
