Cost-benefit Analysis of IUI and IVF based on willingness to pay approach; case study: Iran

Systematic review of the economic evaluation model of assisted reproductive technology

BACKGROUND

With the increasing demand for fertility services, it is urgent to select the most cost-effective assisted reproductive technology (ART) treatment plan and include it in medical insurance. Economic evaluation reports are an important reference for medical insurance negotiation. The aim of this study is to systematically evaluate the economic evaluation research of ART, analyze the existing shortcomings, and provide a reference for the economic evaluation of ART.

METHODS

PubMed, EMbase, Web of Science, Cochrane Library and ScienceDirect databases were searched for relevant articles on the economic evaluation of ART. These articles were screened, and their quality was evaluated based on the Comprehensive Health Economics Evaluation Report Standard (CHEERS 2022), and the data on the basic characteristics, model characteristics and other aspects of the included studies were summarized.

RESULTS

One hundred and two related articles were obtained in the preliminary search, but based on the inclusion criteria, 12 studies were used for the analysis, of which nine used the decision tree model. The model parameters were mainly derived from published literature and included retrospective clinical data of patients. Only two studies included direct non-medical and indirect costs in the cost measurement. Live birth rate was used as an outcome indicator in half of the studies.

CONCLUSION

Suggesting the setting of the threshold range in the field of fertility should be actively discussed, and the monetary value of each live birth is assumed to be in a certain range when the WTP threshold for fertility is uncertain. The range of the parameter sources should be expanded. Direct non-medical and indirect costs should be included in the calculation of costs, and the analysis should be carried out from the perspective of the whole society. In the evaluation of clinical effect, the effectiveness and safety indexes should be selected for a comprehensive evaluation, thereby making the evaluation more comprehensive and reliable. At least subgroup analysis based on age stratification should be considered in the relevant economic evaluation.

IVF versus IUI with ovarian stimulation for unexplained infertility: a collaborative individual participant data meta-analysis

BACKGROUND

IVF and IUI with ovarian stimulation (IUI-OS) are widely used in managing unexplained infertility. IUI-OS is generally considered first-line therapy, followed by IVF only if IUI-OS is unsuccessful after several attempts. However, there is a growing interest in using IVF for immediate treatment because it is believed to lead to higher live birth rates and shorter time to pregnancy.

OBJECTIVE AND RATIONALE

Randomized controlled trials (RCTs) comparing IVF versus IUI-OS had varied study designs and findings. Some RCTs used complex algorithms to combine IVF and IUI-OS, while others had unequal follow-up time between arms or compared treatments on a per-cycle basis, which introduced biases. Comparing cumulative live birth rates of IVF and IUI-OS within a consistent time frame is necessary for a fair head-to-head comparison. Previous meta-analyses of RCTs did not consider the time it takes to achieve pregnancy, which is not possible using aggregate data. Individual participant data meta-analysis (IPD-MA) allows standardization of follow-up time in different trials and time-to-event analysis methods. We performed this IPD-MA to investigate if IVF increases cumulative live birth rate considering the time leading to pregnancy and reduces multiple pregnancy rate compared to IUI-OS in couples with unexplained infertility.

SEARCH METHODS

We searched MEDLINE, EMBASE, CENTRAL, PsycINFO, CINAHL, and the Cochrane Gynaecology and Fertility Group Specialised Register to identify RCTs that completed data collection before June 2021. A search update was carried out in January 2023. RCTs that compared IVF/ICSI to IUI-OS in couples with unexplained infertility were eligible. We invited author groups of eligible studies to join the IPD-MA and share the deidentified IPD of their RCTs. IPD were checked and standardized before synthesis. The quality of evidence was assessed using the Risk of Bias 2 tool.

OUTCOMES

Of eight potentially eligible RCTs, two were considered awaiting classification. In the other six trials, four shared IPD of 934 women, of which 550 were allocated to IVF and 383 to IUI-OS. Because the interventions were unable to blind, two RCTs had a high risk of bias, one had some concerns, and one had a low risk of bias. Considering the time to pregnancy leading to live birth, the cumulative live birth rate was not significantly higher in IVF compared to that in IUI-OS (4 RCTs, 908 women, 50.3% versus 43.2%, hazard ratio 1.19, 95% CI 0.81-1.74, I2 = 42.4%). For the safety primary outcome, the rate of multiple pregnancy was not significantly lower in IVF than IUI-OS (3 RCTs, 890 women, 3.8% versus 5.2% of all couples randomized, odds ratio 0.78, 95% CI 0.41-1.50, I2 = 0.0%).

WIDER IMPLICATIONS

There is no robust evidence that in couples with unexplained infertility IVF achieves pregnancy leading to live birth faster than IUI-OS. IVF and IUI-OS are both viable options in terms of effectiveness and safety for managing unexplained infertility. The associated costs of interventions and the preference of couples need to be weighed in clinical decision-making.

A cost-benefit analysis of genetic screening test for breast cancer in Iran

BACKGROUND

This study aimed to evaluate the implementation of the population- and family history (FH) -based screening for BReast CAncer (BRCA) in Iran, a country where less than 10% of breast cancer cases are attributable to a gene mutation.

METHODS

This was an economic evaluation study. The Benefit-Cost Ratio (BCR) for genetic screening test strategies in Iranian women older than 30 was calculated. To this end, the monetary value of the test was estimated using the willingness-to-pay (WTP) approach using the contingent valuation method (CVM) by payment card. From a healthcare perspective, direct medical and non-medical costs were considered and a decision model for the strategies was developed to simulate the costs. A one-way sensitivity analysis assessed the robustness of the analysis. The data were analyzed using Excel 2010.

RESULTS

660 women were included for estimating WTP and 2,176,919 women were considered in the costing model. The cost per genetic screening test for population- and FH-based strategies was $167 and $8, respectively. The monetary value of a genetic screening test was $20 and it was $27 for women with a family history or gene mutation in breast cancer. The BCR for population-based and FH-based screening strategies was 0.12 and 3.37, respectively. Sensitivity analyses confirmed the robustness of the results.

CONCLUSIONS

This study recommends the implementation of a FH-based strategy instead of a population-based genetic screening strategy in Iran, although a cascade genetic screening test strategy should be evaluated in future studies.

Financial decision analysis based on "willingness to pay" for surgical sperm retrieval approaches among men with non-obstructive azoospermia in the United States

OBJECTIVE

To determine the most financially optimal surgical approach for testicular sperm retrieval for men with non-obstructive azoospermia.

DESIGN

A decision tree was created examining five potential surgical approaches for men with non-obstructive azoospermia pursuing one cycle of intracytoplasmic sperm injection. An expected financial net loss was determined for each surgical option based on couples' willingness to pay for one cycle of intracytoplasmic sperm injection resulting in pregnancy. The branch with the lowest expected net loss was defined as the most optimal financial decision (minimizing loss to a couple). Fresh testicular sperm extraction implied testicular sperm extraction was performed in conjunction with programmed ovulation induction. Frozen testicular sperm extraction implied testicular sperm extraction was performed initially, and ovulation induction/intracytoplasmic sperm injection was canceled if sperm retrieval failed.  The surgical options included fresh conventional testicular sperm extraction, with and without "back-up" sperm cryopreservation, fresh microsurgical testicular sperm extraction, with and without "back-up" sperm cryopreservation, and frozen microsurgical testicular sperm extraction. Success was defined as pregnancy after one intracytoplasmic sperm injection cycle.

MATERIALS AND METHODS

Probabilities of successful sperm retrieval with conventional testicular sperm extraction/microsurgical testicular sperm extraction, post-thaw sperm cellular loss following frozen microsurgical testicular sperm extraction, ovulation induction/intracytoplasmic sperm injection cycle out-of-pocket costs, intracytoplasmic sperm injection pregnancy rates for men with non-obstructive azoospermia, standard conventional testicular sperm extraction cost and average willingness to pay for intracytoplasmic sperm injection cycle were gathered from the systematic literature review. Costs were in USD and adjusted to inflation (as of April 2020). Two-way sensitivity analysis was performed on varying couples' willingness to pay for one cycle of intracytoplasmic sperm injection and varying microsurgical testicular sperm extraction out-of-pocket costs.

RESULTS

According to our decision tree analysis (assuming minimum microsurgical testicular sperm extraction cost of $1,000 and willingness to pay of $8,000), the expected net loss for each branch was as follows: -$17,545 for fresh conventional testicular sperm extraction, -$17,523 for fresh microsurgical testicular sperm extraction, -$9,624 for frozen microsurgical testicular sperm extraction, -$17,991 for fresh conventional testicular sperm extraction with "backup", and -$18,210 for fresh microsurgical testicular sperm extraction with "backup". Two-way sensitivity analysis with a variable willingness to pay values and microsurgical testicular sperm extraction and in-vitro fertilization costs confirmed that frozen microsurgical testicular sperm extraction consistently presented the lowest net loss compared to other options. Interestingly, when directly comparing fresh microsurgical testicular sperm extraction and conventional testicular sperm extraction with "back-up", scenarios with decreasing willingness to pay and lower microsurgical testicular sperm extraction costs demonstrated fresh conventional testicular sperm extraction with "back-up" as more optimal than fresh microsurgical testicular sperm extraction with "back-up".

CONCLUSIONS

For those couples who must pay out of pocket, our study suggests that frozen microsurgical testicular sperm extraction is the most financially optimal decision for the surgical management of non-obstructive azoospermia, regardless of microsurgical testicular sperm extraction cost and the couple's willingness to pay.

Effect of Heartfulness meditation based integrative therapy on infertility outcomes: A retrospective case series evaluation

BACKGROUND

In Indian context, infertility is often a silent struggle. Despite the high prevalence of infertility in the country, the majority of couples do not share their struggles with family or friends due to social stigma, thus increasing their psychological vulnerability. Heartfulness meditation has shown to decrease stress, anxiety, loneliness and improve sleep along with quality of life.

OBJECTIVES

The current retrospective series evaluated the effectiveness of Heartfulness-based integrative therapy on infertility outcomes.

METHODS

The program consisted of a 5- day onsite lifestyle modification workshop and online follow up meditation sessions.

RESULTS

54 couples with infertility participated in the program with a mean age of 30.74 years (SD 5.04) for females and 34.03 years (SD 4.54) for males. 15 couples presented with male infertility, 16 couples presented with female infertility and in 5 couples both partners had infertility problems. Further, 18 couples had unexplained infertility. 24 couples conceived with 18 natural conceptions, five via assisted reproductive technology and one spontaneous abortion.

CONCLUSION

The program was beneficial in the cohort who utilized it as prescribed resulting in conception of 24 out of 54 couples. Future research investigating the causal relationship of Heartfulness meditation on fertility outcomes in a randomized control study could solidify this treatment method to be used independently or as an adjuvant therapy with assisted reproductive technologies.

Economic Evaluation of Medically Assisted Reproduction: A Methodological Systematic Review

BACKGROUND

Medically assisted reproduction (MAR) is a challenging application area for health economic evaluations, entailing a broad range of costs and outcomes, stretching out long-term and accruing to several parties.

PURPOSE

To systematically review which costs and outcomes are included in published economic evaluations of MAR and to compare these with health technology assessment (HTA) prescriptions about which cost and outcomes should be considered for different evaluation objectives.

DATA SOURCES

HTA guidelines and systematic searches of PubMed Central, Embase, WOS CC, CINAHL, Cochrane (CENTRAL), HTA, and NHS EED.

STUDY SELECTION

All economic evaluations of MAR published from 2010 to 2022.

DATA EXTRACTION

A predetermined data collection form summarized study characteristics. Essential costs and outcomes of MAR were listed based on HTA and treatment guidelines for different evaluation objectives. For each study, included costs and outcomes were reviewed.

DATA SYNTHESIS

The review identified 93 cost-effectiveness estimates, of which 57% were expressed as cost-per-(healthy)-live-birth, 19% as cost-per-pregnancy, and 47% adopted a clinic perspective. Few adopted societal perspectives and only 2% used quality-adjusted life-years (QALYs). Broader evaluations omitted various relevant costs and outcomes related to MAR. There are several cost and outcome categories for which available HTA guidelines do not provide conclusive directions regarding inclusion or exclusion.

LIMITATIONS

Studies published before 2010 and of interventions not clearly labeled as MAR were excluded. We focus on methods rather than which MAR treatments are cost-effective.

CONCLUSIONS

Economic evaluations of MAR typically calculate a short-term cost-per-live-birth from a clinic perspective. Broader analyses, using cost-per-QALY or BCRs from societal perspectives, considering the full scope of reproduction-related costs and outcomes, are scarce and often incomplete. We provide a summary of costs and outcomes for future research guidance and identify areas requiring HTA methodological development.

HIGHLIGHTS

The cost-effectiveness of MAR procedures can be exceptionally complex to estimate as there is a broad range of costs and outcomes involved, in principle stretching out over multiple generations and over many stakeholders.We list 21 key areas of costs and outcomes of MAR. Which of these needs to be accounted for alters for different evaluation objectives (determined by the type of economic evaluation, time horizon considered, and perspective).Published studies mostly investigate cost-effectiveness in the very short-term, from a clinic perspective, expressed as cost-per-live-birth. There is a lack of comprehensive economic evaluations that adopt a broader perspective with a longer time horizon. The broader the evaluation objective, the more relevant costs and outcomes were excluded.For several costs and outcomes, particularly those relevant for broader, societal evaluations of MAR, the inclusion or exclusion is theoretically ambiguous, and HTA guidelines do not offer sufficient guidance.

The Effect of Metabolic Persian Diet on Ovulation Induction in Infertile Women

Introduction

Infertility is an important issue with a high social and psychological burden. From the perspective of Persian Medicine (PM), uterine cold temperament is one of the important causes of female infertility.

Aim

The aim of this study was to study the effect of PM or Iranian traditional medicine on improving ovulation and fertility.

Methods

From January 2017 to August 2017, sixty infertile women with eugonadotropic ovulation disorder were randomly divided into two groups. Both groups were treated with clomiphene citrate, except that the intervention group also received metabolic Persian diet (MPD). In each cycle, the dominant follicles and endometrium were investigated with ultrasound. At the end of the cycle, beta human chorionic gonadotropin (β-HCG) was evaluated and if positive, another ultrasound was performed two weeks later to confirm early pregnancy.

Results

The number of dominant follicles from the first to third cycle increased from 2.15 ± 1.14 to 2.28 ± 0.61 in the intervention group and decreased from 1.86 ± 0.79 to 1.30 ± 0.47 in the control group. The dominant follicle size changed from 16.00 ± 4.08 to 18.78 ± 2.78 and from 15.05 ± 3.11 to 15.80 ± 3.89 in the intervention and control groups, respectively. But endometrial thickness did not change significantly in the intervention group. Pregnancy results based on β-HCG and ultrasound findings were positive in 19 and 16 patients in the intervention group and in 10 and 7 patients in the control group, implying significantly higher numbers in the first group.

Conclusion

It seems that MPD may be effective in the success of ovulation induction.

The value of treatment for infertility: A systematic literature review of willingness-to-pay thresholds and approaches for determining the cost effectiveness of fertility therapies

Willingness to pay (WTP) for an infertility treatment is the maximum amount of money a patient is willing to pay per treatment, or to achieve a live birth or pregnancy. Such thresholds are important to determine the cost effectiveness of a treatment. A systematic review was conducted to identify and explore the studies that attempt to ascertain WTP for infertility and compare them with the cost-effectiveness studies that claimed to use WTP thresholds. For comparison, all the costs were converted and inflated to 2021 euros. The results demonstrated that there were no standard outcomes or WTP thresholds for an outcome/treatment, and the methodologies used vary. Cost-effectiveness studies either used the incremental cost-effectiveness ratio to imply a WTP threshold, or used thresholds that were previously accepted for a quality-adjusted life year outcome converted, inappropriately, to an infertility outcome. There is a need for further research by health economists to develop a consensus for the meaningful assessment of WTP for ART.

Does in vitro fertilization (IVF) treatment provide good value for money? A cost-benefit analysis

Background

Using traditional health technology assessment (HTA) outcome metrics, such as quality-adjusted life-years, to assess fertility treatments raises considerable methodological challenges because the objective of fertility treatments is to create new life rather than extend, save, or improve health-related quality of life.

Objective

The aim of this study was to develop a novel cost-benefit framework to assess value for money of publicly funded IVF treatment; to determine the number of cost-beneficial treatment cycles for women of different ages; and to perform an incremental cost-benefit analysis from a taxpayer perspective.

Methods

We developed a Markov model to determine the net monetary benefit (NMB) of IVF treatment by female age and number of cycles performed. IVF treatment outcomes were monetized using taxpayers' willingness-to-pay values derived from a discrete choice experiment (DCE). Using the current funding environment as the comparator, we performed an incremental analysis of only funding cost-beneficial cycles. Similar outputs to cost-effectiveness analyses were generated, including net-benefit acceptability curves and cost-benefit planes. We created an interactive online app to provide a detailed and transparent presentation of the results.

Results

The results suggest that at least five publicly funded IVF cycles are cost-beneficial in women aged <42 years. Cost-benefit planes suggest a strong taxpayer preference for restricting funding to cost-beneficial cycles over current funding arrangements in Australia from an economic perspective.

Conclusions

The provision of fertility treatment is valued highly by taxpayers. This novel cost-benefit method overcomes several challenges of conventional cost-effectiveness methods and provides an exemplar for incorporating DCE results into HTA. The results offer new evidence to inform discussions about treatment funding arrangements.

What Features of Fertility Treatment do Patients Value? Price Elasticity and Willingness-to-Pay Values from a Discrete Choice Experiment

BACKGROUND

Infertility is a medical condition affecting an estimated 186 million people worldwide. Medically assisted fertility treatments allow many of these individuals to have a baby. Insights about preferences of patients who have experienced fertility treatment should be used to inform funding policies and treatment configurations that best reflect the patients' voice and the value of fertility treatment to patients.

OBJECTIVE

To explore the preferences for fertility treatment attributes of infertile women who had previously undergone or were undergoing fertility treatments-ex post perspective.

METHODS

We used data from a stated-preference discrete choice experiment (DCE) among 376 Australian women who had undergone or were undergoing fertility treatment. Respondents chose their preferred treatment choices in 12 hypothetical treatment choice scenarios described by seven attributes (success rates, side effects, counselling/peer support, treatment journey, continuity of care, availability of experimental treatment and out-of-pocket cost). We estimated random parameter logit (RPL) and latent class (LC) models that accounted for preference heterogeneity. The results were used to derive price elasticities of demand and marginal willingness-to-pay (WTP) values for the treatment attributes explored within the DCE survey.

RESULTS

Income level did not have a significant effect on marginal WTP for fertility treatment attributes. The demand for fertility treatment from an ex post perspective was found to be highly inelastic (treatment cost changes had almost no impact on demand). Success rates and out-of-pocket costs were significant and important predictors of individuals' treatment choices conditional on the attributes and levels included in the study. These were followed by counselling/peer support, side effects, treatment journey, continuity of care, and availability of experimental treatment, in that order. Respondents were willing to pay $383-$524 per one percentage point increase in the treatment success rate and over $2000 and over $3500 to avoid moderate and significant side effects, respectively (values are reported in AU$). Latent class models revealed that the majority of respondents (51%) were risk-averse success-rate seekers.

CONCLUSION

Infertile women who had previously undergone or were undergoing fertility treatment valued fertility treatment highly as reflected by highly price-inelastic demand. Success rate of treatment and out-of-pocket costs were the most important attributes and largely determined patients' WTP for fertility treatment relative to the attributes and levels used in the study. While further research should investigate the price sensitivity of women who have not experienced fertility treatment, these results might explain why women continue fertility treatment once they have commenced despite their financial capacity to pay. Future research should also determine patients' price elasticities for a fertility treatment program with multiple treatment cycles.

Cost-benefit analysis of Intensive Care Unit with Activity-Based Costing approach in the era COVID-19 pandemic: A case study from Iran

BACKGROUND

Providing intensive care to acute patients is a vital part of health systems. However, the high cost of Intensive Care Units (ICU) has limited their development, especially in low-income countries. Due to the increasing need for intensive care and limited resources, ICU cost management is important. This study aimed to analyze the cost-benefit of ICU during COVID-19 in Tehran, Iran.

METHODS

This cross-sectional study is an economic evaluation of health interventions. The study was conducted in the COVID-19 dedicated ICU, from the provider's point of view and within one-year horizon. Costs were calculated using a top-down approach and the Activity-Based Costing technique. Benefits were extracted from the hospital's HIS system. Benefit Cost ratio (BCR) and Net Present Value (NPV) indexes were used for cost-benefit analysis (CBA). A sensitivity analysis was performed to evaluate the dependence of the CBA results on the uncertainties in the cost data. Analysis was performed with Excel and STATA software.

RESULTS

The studied ICU had 43 personnel, 14 active beds, a 77% bed occupancy rate, and 3959 occupied bed days. The total costs were $2,372,125.46 USD, of which 70.3% were direct costs. The highest direct cost was related to human resources. The total net income was $1,213,314.13 USD. NPV and BCR were obtained as $-1,158,811.32 USD and 0.511 respectively.

CONCLUSION

Despite operating with a relatively high capacity, ICU has had high losses during the COVID-19. Proper management and re-planning in the structure of human resources is recommended due to its importance in the hospital economy, provision of resources based on needs assessment, improvement of drugs management, reduction of insurance deductions in order to reduce costs and improve ICU productivity.

Economic evaluation of Medically Assisted Reproduction: An educational overview of methods and applications for healthcare professionals

Economic evaluations of the value-for-money of Medically Assisted Reproduction (MAR) interventions are increasingly important due to growing pressure on healthcare budgets. Although such evaluations are commonplace in the published literature, the number/methodological complexity of different evaluations available, and the challenges specific to MAR interventions, can complicate the interpretation of such analyses for fertility treatments. This article aims to serve as an educational resource and provide context on the design/interpretation of economic analyses for MAR interventions. Several areas are relevant for first-line providers and decision makers: scope of analysis, comparator used, perspective/time horizon considered, outcomes used to measure success, and how results from cost-effectiveness studies can be summarised and used in clinical practice. We aim to help clinicians better understand the strengths/weaknesses of economic analyses, to enable the best use of the evidence in practice, so resources available for MAR interventions can provide maximum value to patients and society.

Secondary infertility with a history of vaginal childbirth: Ready to have another one?

INTRODUCTION

Up to 30% of couples may face secondary infertility. The impact of ectopic pregnancy, spontaneous abortion, pregnancy termination or live birth with caesarean section may impair further fertility in different ways. However, secondary infertility after physiological vaginal life childbirth has been little studied. The aim of this study was to describe the population and the fertility issues and analyze the predictive factors of success in in vitro fertilization in women presenting secondary infertility after a physiological vaginal childbirth.

MATERIAL AND METHODS

This single-centre retrospective study included women aged 18-43 years consulting between 2013 and 2020 for secondary infertility in a couple having already had previous vaginal life childbirth. Couples' characteristics, management decision after the first consultation and IVF outcomes were analyzed.

RESULTS

Secondary infertility was found in 286 couples, out of whom 138 had a history of vaginal life childbirth. Population was characterized by an advanced female age and overweight. After the first consultation, IVF was performed in only 40% of couples. No predictive factor of live birth was found.

CONCLUSION

Our study shows that in couples with secondary infertility after prior physiological delivery cigarette smoking is frequent in male partners, and ovarian reserve markers are altered. However, no statistically significant predictive factor of live birth after IVF treatment has been identified. Further large prospective studies are necessary.
