Economic value of diastasis repair with the use of mesh compared to no intervention in Italy

AIM

Rectus abdominal diastasis (RAD) can cause mainly incontinence and lower-back pain. Despite its high incidence, there is no consensus regarding surgical indication. We aimed at comparing RAD repair (minimally invasive technique with mesh implant) with no treatment (standard of care - SOC) through cost-effectiveness and budget impact analyses from both National Healthcare Service (NHS) and societal perspectives in Italy.

METHODS

A model was developed including social costs and productivity losses derived by the online administration of a socio-economic questionnaire, including the EuroQol for the assessment of quality of life. Costs for the NHS were based on reimbursement tariffs.

RESULTS

Over a lifetime horizon, estimated costs were 64,115€ for SOC and 46,541€ for RAD repair in the societal perspective; QALYs were 19.55 and 25.75 for the two groups, respectively. Considering the NHS perspective, RAD repair showed an additional cost per patient of 5,104€ compared to SOC, leading to an ICUR of 824€. RAD repair may be either cost-saving or cost-effective compared to SOC depending on the perspective considered. Considering a current scenario of 100% SOC, an increased diffusion of RAD repair from 2 to 10% in the next 5 years would lead to an incremental cost of 184,147,624€ for the whole society (87% borne by the NHS) and to incremental 16,155 QALYs.

CONCLUSION

In light of the lack of economic evaluations for minimally invasive RAD repair, the present study provides relevant clinical and economic evidence to help improving the decision-making process and allocating scarce resources between competing ends.

Cost-Effectiveness Analysis of HRD Testing for Previously Treated Patients with Advanced Ovarian Cancer in Italy

INTRODUCTION

Ovarian cancer (OC) is the eighth most common cancer among women, and homologous recombination deficiency (HRD) is present in approximately 50% of these patients. For this group, poly(ADP-ribose) polymerase (PARP) inhibitors are more likely to be effective. The aim of the study was to investigate the cost-effectiveness of HRD testing versus BRCA testing (which identifies mutations present only in 25% of patients) in Italy to optimize the treatment management, possibly with PARP inhibitors.

METHODS

A cost-effectiveness partition survival model was developed to estimate the expected costs and outcomes (life years, LYs; quality-adjusted life years, QALYs) with lifetime horizon of HRD testing versus BRCA testing alone in women with high-grade serous or endometrioid advanced ovarian cancer. The option to perform the tests in sequence, that is, the BRCA test followed by the HRD test, in patients with BRCA-negative test was also considered, and the model accounted for the National Healthcare Service (NHS) perspective in Italy. The treatments represented the best available options according to the initial test results and according to PARP inhibitors available in Italy. A 3% discount rate was applied. Both deterministic and probabilistic sensitivity analyses were performed to test the robustness of the model results.

RESULTS

HRD testing was shown to be a cost-effective strategy compared to BRCA testing (incremental cost-utility ratio 22,610€/QALY) and a cost-saving strategy compared to the sequence of tests. The probabilistic sensitivity analysis showed that the HRD test is cost-effective compared to BRCA testing in 98.5% of model simulations considering a willingness-to-pay threshold of 50,000€/QALY.

CONCLUSION

The identification of genetic anomalies in patients with advanced OC is a costly process. Regardless, HRD upfront testing compared to BRCA testing had a cost-effective profile, allowing the efficient use of healthcare resources and better life expectancy and quality of life for patients.

Cost-effectiveness analysis of pressure-controlled intermittent coronary sinus occlusion in elective percutaneous coronary intervention

OBJECTIVES

Percutaneous coronary intervention (PCI) represents the standard treatment for ST-elevated myocardial infarction, nevertheless, mortality and heart failures are frequent. Pressure-controlled intermittent coronary sinus occlusion (PiCSO) might reduce infarct size showing better patients' outcomes. We evaluated the cost-effectiveness of PCI+PiCSO compared to PCI from the National Healthcare Service (NHS) perspective in Italy.

METHODS

A Markov model was developed to estimate life years (LYs), quality-adjusted life years (QALYs) and costs. A micro-costing analysis has been performed to inform the cost of PCI+PiCSO procedure. Sensitivity analyses were performed to test the robustness of the model results.

RESULTS

Considering a willingness-to-pay threshold of 50,000€/QALY for the ICUR and a cost for PCI+PiCSO procedure of 14,654€, the innovative strategy may be cost-effective compared to PCI alone from the Italian NHS perspective, showing an ICUR of 17,530€/QALY (ICER 14,631€/LY) over a lifetime horizon; the probabilistic sensitivity analysis showed that PCI+PiCSO is cost-effective in 78.8% of simulations.Considering the above mentioned willingness-to-pay threshold, PCI+PiCSO strategy would be cost-effective over a lifetime horizon considering a cost for PCI+PiCSO procedure lower than 28,160€.

CONCLUSION

PCI+PiCSO procedure may be considered a cost-effective technology that allows reducing cardiac events, while improving patients' life expectancy and quality of life.

Cost-Utility Analysis of Esketamine for Patients with Treatment-Resistant Depression in Italy

AIM

Major depressive disorder is considered one of the most frequent diseases in the general population, and treatment-resistant depression (TRD) represents the subset with more significant clinical and social impact. Large, robust phase III studies have shown safety and efficacy of esketamine nasal spray plus SSRI/SNRI antidepressants (ADs) compared with SSRI/SNRI plus placebo nasal spray in patients with TRD. The main aim of this study was to perform a cost-utility analysis comparing esketamine plus ADs with ADs alone in TRD patients, from the societal perspective in Italy. A secondary analysis focused on the National Healthcare Service (NHS) perspective.

METHODS

A Markov multistate model has been developed to estimate quality-adjusted life years and economic outcomes of both treatment strategies over 5 years considering the initiation of esketamine in the different treatment lines, from 3 to 5 (3L-5L). The model has been populated with data from literature and real-world evidence. The analysis from the societal perspective considered direct healthcare costs and patients' productivity losses. In addition to the incremental cost-utility ratio (ICUR), the incremental net monetary benefit (INMB) has been calculated as (incremental benefit × WTP) - incremental cost and by applying a willingness-to-pay (WTP) of 50,000€/QALY. Deterministic and probabilistic sensitivity analyses have been performed to assess the robustness of the model results.

RESULTS

From the societal perspective, the ICUR ranged between 16,314€ and 22,133€ per QALY according to the different treatment lines, while it was over the threshold of 100,000€/QALY for the NHS perspective. The INMB was positive and ranged from 2259€ to 2744€ across treatment lines in the societal perspective; the INMB begins to occur earlier when moving towards subsequent lines of treatment (3.9 years for 3L, 3.6 years for 4L and 3.5 years for 5L). The analyses showed also that the advantage in terms of INMB is maintained for a wide range of societal preferences expressed by WTP thresholds, and in particular for values above 22,200€, 16,400€ and 17,100€ for 3L, 4L and 5L, respectively.

CONCLUSION

The study showed that esketamine may be a cost-effective opportunity from the societal perspective for the management of patients with treatment-resistant depression. In the future, data collected from observational studies or registries, which can include the collection of productivity losses and also costs sustained by the patients, will be able to provide further evidence in order to improve the reliability of the model results.

Cost-effectiveness analysis of personalised versus standard dosimetry for selective internal radiation therapy with TheraSphere in patients with hepatocellular carcinoma

Aims

To perform a cost-effectiveness analysis (CEA) comparing personalised dosimetry with standard dosimetry in the context of selective internal radiation therapy (SIRT) with TheraSphere for the management of adult patients with locally advanced hepatocellular carcinoma (HCC) from the Italian Healthcare Service perspective.

Materials and methods

A partition survival model was developed to project costs and the quality-adjusted life years (QALYs) over a lifetime horizon. Clinical inputs were retrieved from a published randomised controlled trial. Health resource utilisation inputs were extracted from the questionnaires administered to clinicians in three oncology centres in Italy, respectively. Cost parameters were based on Italian official tariffs.

Results

Over a lifetime horizon, the model estimated the average QALYs of 1.292 and 0.578, respectively, for patients undergoing personalised and standard dosimetry approaches. The estimated mean costs per patient were €23,487 and €19,877, respectively. The incremental cost-utility ratio (ICUR) of personalised versus standard dosimetry approaches was €5,056/QALY.

Conclusions

Personalised dosimetry may be considered a cost-effective option compared to standard dosimetry for patients undergoing SIRT for HCC in Italy. These findings provide evidence for clinicians and payers on the value of personalised dosimetry as a treatment option for patients with HCC.

Integrated intErventional bronchoscopy in the treatment of locally adVanced non-small lung cancER with central Malignant airway Obstructions: a multicentric REtrospective study (EVERMORE)

OBJECTIVES

Despite new therapeutic perspectives, the presence of central airways occlusion (CAO) in patients with locally advanced non-small cell lung cancer (NSCLC) is associated with poor survival. There is no clear evidence on the clinical impact of interventional bronchoscopy as a part of an integrated treatment to cure these patients.

MATERIALS AND METHODS

This retrospective cohort study was conducted in two teaching hospitals over a 10 years period (January 2010-January 2020) comparing patients with NSCLC at stage IIIB and CAO at disease onset treated with chemotherapy/radiotherapy (standard therapy-ST) with those receiving interventional bronchoscopy plus ST (integrated treatment-IT). Primary outcome was 1-year survival. The onset of respiratory events, symptoms-free interval, hospitalization, need for palliation, and overall mortality served as secondary outcomes.

RESULTS

A total of 100 patients were included, 60 in the IT and 40 in the ST group. Unadjusted Kaplan-Meier estimates showed greater effect of IT compared to ST on 1-year survival (HR = 2.1 95%CI[1.1-4.8], p = 0.003). IT showed a significantly higher survival gain over ST in those patients showing KRAS mutation (7.6 VS 0.8 months,<0.0001), a lumen occlusion >65% (6.6 VS 2.9 months,<0.001), and lacking the involvement of left bronchus (7 VS 2.3 months,<0.0001). Compared to ST, IT also showed a favorable difference in terms of new hospitalizations (p = 0.03), symptom-free interval (p = 0.02), and onset of atelectasis (p = 0.01).

CONCLUSIONS

In patients with NSCLC stage IIIB and CAO, additional interventional bronchoscopy might impact on 1-year survival. Genetic and anatomic phenotyping might allow identifying those patients who may gain life expectancy from the endoscopic intervention.
