Economic evaluations of assisted reproductive technologies in high-income countries: a systematic review

STUDY QUESTION

Which assited reproductive technology (ART) interventions in high-income countries are cost-effective and which are not?

SUMMARY ANSWER

Among all ART interventions assessed in economic evaluations, most high-cost interventions, including preimplantation genetic testing for aneuploidy (PGT-A) for a general population and ICSI for unexplained infertility, are unlikely to be cost-effective owing to minimal or no increase in effectiveness.

WHAT IS KNOWN ALREADY

Approaches to reduce costs in order to increase access have been identified as a research priority for future infertility research. There has been an increasing number of ART interventions implemented in routine clinical practice globally, before robust assessments of evidence on economic evaluations. The extent of clinical effectiveness of some studied comparisons has been evaluated in high-quality research, allowing more informative decision making around cost-effectiveness.

STUDY DESIGN, SIZE, DURATION

We performed a systematic review and searched seven databases (MEDLINE, PUBMED, EMBASE, COCHRANE, ECONLIT, SCOPUS, and CINAHL) for studies examining ART interventions for infertility together with an economic evaluation component (cost-effectiveness, cost-benefit, cost-utility, or cost-minimization assessment), in high-income countries, published since January 2011. The last search was 22 June 2022.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Two independent reviewers assessed publications and included those fulfilling the eligibility criteria. Studies were examined to assess the cost-effectiveness of the studied intervention, as well as the reporting quality of the study. The chosen outcome measure and payer perspective were also noted. Completeness of reporting was assessed against the Consolidated Health Economic Evaluation Reporting Standard. Results are presented and summarized based on the intervention studied.

MAIN RESULTS AND THE ROLE OF CHANCE

The review included 40 studies which were conducted in 11 high-income countries. Most studies (n = 34) included a cost-effectiveness analysis. ART interventions included medication or strategies for controlled ovarian stimulation (n = 15), IVF (n = 9), PGT-A (n = 7), single embryo transfer (n = 5), ICSI (n = 3), and freeze-all embryo transfer (n = 1). Live birth was the mostly commonly reported primary outcome (n = 27), and quality-adjusted life years was reported in three studies. The health funder perspective was used in 85% (n = 34) of studies. None of the included studies measured patient preference for treatment. It remains uncertain whether PGT-A improves pregnancy rates compared to IVF cycles managed without PGT-A, and therefore cost-effectiveness could not be demonstrated for this intervention. Similarly, ICSI in non-male factor infertility appears not to be clinically effective compared to standard fertilization in an IVF cycle and is therefore not cost-effective. Interventions such as use of biosimilars or HMG for ovarian stimulation are cheaper but compromise clinical effectiveness.

LIMITATIONS, REASONS FOR CAUTION

Lack of both preference-based and standardized outcomes limits the comparability of results across studies. The selection of efficacy evidence offered for some interventions for economic evaluations is not always based on high-quality randomized trials and systematic reviews. In addition, there is insufficient knowledge of the willingness to pay thresholds of individuals and state funders for treatment of infertility. There is variable quality of reporting scores, which might increase uncertainty around the cost-effectiveness results.

WIDER IMPLICATIONS OF THE FINDINGS

Investment in strategies to help infertile people who utilize ART is justifiable at both personal and population levels. This systematic review may assist ART funders decide how to best invest to maximize the likelihood of delivery of a healthy child.

Preimplantation genetic testing for BRCA gene mutation carriers: a cost effectiveness analysis

BACKGROUND

Gynecologic oncologists should be aware of the option of conception through IVF/PGT-M for families with high BRCA related morbidity or mortality. Our objective was to investigate the cost-effectiveness of preimplantation genetic testing for selection and transfer of BRCA negative embryo in BRCA mutation carriers compared to natural conception.

METHODS

Cost-effectiveness of two strategies, conception through IVF/PGT-M and BRCA negative embryo transfer versus natural conception with a 50% chance of BRCA positive newborn for BRCA mutation carriers was compared using a Markovian process decision analysis model. Costs of the two strategies were compared using quality adjusted life years (QALYs'). All costs were discounted at 3%. Incremental cost effectiveness ratio (ICER) compared to willingness to pay threshold was used for cost-effectiveness analysis.

RESULTS

IVF/ PGT-M is cost-effective with an ICER of 150,219 new Israeli Shekels, per QALY gained (equivalent to 44,480 USD), at a 3% discount rate.

CONCLUSIONS

IVF/ PGT-M and BRCA negative embryo transfer compared to natural conception among BRCA positive parents is cost effective and may be offered for selected couples with high BRCA mutation related morbidity or mortality. Our results could impact decisions regarding conception among BRCA positive couples and health care providers.

The prevalence, promotion and pricing of three IVF add-ons on fertility clinic websites

RESEARCH QUESTION

How are IVF clinic websites advertising three common IVF add-ons: assisted hatching, time-lapse embryo imaging and preimplantation genetic testing for aneuploidies (PGT-A)?

DESIGN

The Human Fertilisation and Embryology Authority 'Choose a fertility clinic' website service was used to identify IVF clinics and their websites. Assisted hatching, time-lapse embryo imaging and PGT-A were examined to determine which websites advertised them, what price they charged and what claims they made in relation to the add-ons.

RESULTS

Eighty-seven eligible clinics were identified, with 72 unique websites; 37 (43%) clinics were part of one of nine groups of IVF clinics, of sizes ranging from two to eight clinics in the UK. Time-lapse imaging (TLI) was the most frequently advertised of the three add-ons (67% of clinics), followed by PGT-A (47%) and assisted hatching (28%). Very few websites stated that the effectiveness of the add-on was in doubt or unclear (four, two and one websites for TLI, PGT-A and assisted hatching, respectively), and none raised the possibility that an add-on might have negative effects. Claims of efficacy were often based on upstream outcomes (e.g. implantation, pregnancy). Some claims that PGT-A and TLI improved live birth rates were found. There was substantial variation in pricing.

CONCLUSIONS

IVF clinic websites provide valuable information for patients seeking fertility treatment so it is key that the information is accurate and complete. There is a need for transparent information on interventions, including uncertainties and risks, to be made available by IVF clinics to support well-informed treatment decisions. The selected add-ons are widely advertised, and there is wide variation in pricing.

Subsidizing PGD: The Moral Case for Funding Genetic Selection

Preimplantation genetic diagnosis (PGD) allows the detection of genetic abnormalities in embryos produced through in vitro fertilization (IVF). Current funding models in Australia provide governmental subsidies for couples undergoing IVF, but do not extend to PGD. There are strong reasons for publicly funding PGD that follow from the moral principles of autonomy, beneficence and justice for both parents and children. We examine the objections to our proposal, specifically concerns regarding designer babies and the harm of disabled individuals, and show why these are substantially outweighed by arguments for subsidizing PGD. We argue that an acceptance of PGD is aligned with present attitudes towards procreative decision making and IVF use, and that it should therefore receive government funding.

The cost of a euploid embryo identified from preimplantation genetic testing for aneuploidy (PGT-A): a counseling tool

PURPOSE

To determine the expected out-of-pocket costs of IVF with preimplantation genetic testing for aneuploidy (PGT-A) to attain a 50%, 75%, or 90% likelihood of a euploid blastocyst based on individual age and AMH, and develop a personalized counseling tool.

METHODS

A cost analysis was performed and a counseling tool was developed using retrospective data from IVF cycles intended for PGT or blastocyst freeze-all between January 1, 2014 and August 31, 2017 (n = 330) and aggregate statistics on euploidy rates of > 149,000 embryos from CooperGenomics. Poisson regression was used to determine the number of biopsiable blastocysts obtained per cycle, based on age and AMH. The expected costs of attaining a 50%, 75%, and 90% likelihood of a euploid blastocyst were determined via 10,000 Monte Carlo simulations for each age and AMH combination, incorporating age-based euploidy rates and IVF/PGT-A cost assumptions.

RESULTS

The cost to attain a 50% likelihood of a euploid blastocyst ranges from approximately $15,000 U.S. dollars (USD) for younger women with higher AMH values (≥ 2 ng/mL) to > $150,000 for the oldest women (44 years) with the lowest AMH values (< 0.1 ng/mL) in this cohort. The cost to attain a 75% versus 90% likelihood of a euploid blastocyst is similar (~ $16,000) for younger women with higher AMH values, but varies for the oldest women with low AMH values (~ $280,000 and > $450,000, respectively). A typical patient (36-37 years, AMH 2.5 ng/mL) should expect to spend ~ $30,000 for a 90% likelihood of attaining a euploid embryo.

CONCLUSIONS

This tool can serve as a counseling adjunct by providing individualized cost information for patients regarding PGT-A.

A qualitative inquiry of the financial concerns of couples opting to use preimplantation genetic diagnosis to prevent the transmission of known genetic disorders

Preimplantation genetic diagnosis (PGD) is an innovative prenatal testing option because the determination of whether a genetic disorder or chromosomal abnormality is evident occurs prior to pregnancy. However, PGD is not covered financially under the majority of private and public health insurance institutions in the United States, leaving couples to decide whether PGD is financially feasible. The aim of this qualitative study was to understand the role of finances in the decision-making process among couples who were actively considering PGD. In-depth, semi-structured interviews were completed with 18 genetic high-risk couples (36 individual partners). Grounded theory guided the analysis, whereby three themes emerged: 1) Cost is salient, 2) Emotions surrounding affordability, and 3) Financial burden and sacrifice. Ultimately, couples determined that the opportunity to avoid passing on a genetic disorder to a future child was paramount to the cost of PGD, but expressed financial concerns and recognized financial access as a major barrier to PGD utilization.

Preimplantation genetic diagnosis: a systematic review of litigation in the face of new technology

OBJECTIVE

To study legal cases against IVF facilities pertaining to preimplantation genetic diagnosis (PGD) misdiagnosis.

DESIGN

Systematic case law review.

SETTING

University medical center using US legal databases.

PATIENT(S)

The IVF recipients using PGD services.

INTERVENTION(S)

Lawsuits pertaining to PGD against IVF facilities.

MAIN OUTCOME MEASURE(S)

Lawsuits, court rulings, damage awards, and settlements pertaining to PGD after the birth of a child with a genetic defect.

RESULT(S)

Causes of action pertaining to PGD arise from negligence in performing the procedure as well as failure to properly inform patients of key information, such as inherent errors associated with the PGD process, a facility's minimal experience in performing PGD, and the option of obtaining PGD. Courts have sympathized with the financial burden involved in caring for children with disabilities. Monetary damage awards are based on the costs of caring for children with debilitating defects, including lifetime medical and custodial care.

CONCLUSION(S)

Facilities offering PGD services expose themselves to a new realm of liability in which damage awards can easily exceed the limits of a facility's insurance policy. Competent laboratory personnel and proper informed consent--with particular care to inform patients of the inherent inaccuracies of PGD--are crucial in helping deter liability.

Kinderwunsch und Wunschkinder

Definition of problem:

BACKGROUND

Reproductive Biomedicine and new reproductive technologies (ART) belong to the fields of medicine that initiated most of the discussion on enhancement and desire fulfilling medicine in bioethics during the last years. One of the crucial questions to be answered is the definition of the right to procreate/right for a genetically related child. Closely connected are controversial opinions in regard to the definition of sterility as a disease/illness, or a mere fate, or malfunction, which does not have to be medically cured. Arguments: After a cursory description of the national and international debate, we introduce some results of our 'bioethical field studies', exploring and comparing the views of experts (human geneticists, ethicists, pediatricians, obstetricians and midwifes) and couples/patients (IVF couples, high genetic risk couples and couples with no known risk for an inherited disease or infertility problem) on sterility, the right to procreate, possibilities and appropriate limits of IVF in Germany.

CONCLUSION

According to the WHO, sterility has to be defined as an illness, if the respective couples have a desire for a child. IVF can be a means for a cure. Since 2004, Germany does no longer supply a thoroughly insurer financed IVF treatment. Our surveys indicate that this change, though supported by many experts, is hard to accept for couples concerned. Only obstetricians share the WHO's view that sterility should count as an illness. Many ethicists see a proclaimed human right to procreate as merely negative right, although many support free IVF treatment for poor couples. We challenge the expert majority view on the basis of the capability approach (Amartya Sen) and functional liberalism (Herlinde Pauer Studer) and with a view to the international state of the art in IVF. The desire to have children cannot be reduced to a non-authoritative preference whose fulfillment is optional, but has to be conceptualized as a normative need that ought to be met.

Preimplantation genetic diagnosis: technological promise and ethical perils

OBJECTIVE

To describe the ethical issues inherent to the current and foreseeable uses of preimplantation genetic diagnosis (PGD).

DESIGN

Review of ethical principles and their application to PGD.

SETTING

Academic medical center.

PATIENT(S)

None.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

A discussion of the current ethical perils surrounding the use of PGD, and a prediction of future ethical quandaries that will arise from the use of this technology.

RESULT(S)

Although PGD may be used to predict and prevent disease, it may also be used to determine nondisease traits. The ever-expanding ability of genetics to determine qualities of the preimplantation embryo continues to open up new ethical questions relating to the use of PGD for preimplantation diagnosis.

CONCLUSION(S)

Preimplantation genetic diagnosis is a powerful technique with many positive applications. As with all such new technologies, care should be taken to ponder the ethical implications of its use before routinely accepting PGD as a tool in the reproductive armamentarium.

Outcomes of Preimplantation Genetic Diagnosis Therapy in Treatment of β-Thalassemia: A Retrospective Analysis

Thalassemia is one of the most common single-gene disorders that can be cured by hematopoietic stem cell transplantation (HCT) from a human leukocyte antigen (HLA)-identical sibling donor. In families that have an affected child, preimplantation genetic diagnosis (PGD) can be used to select an unaffected, HLA-identical embryo. In brief, this procedure requires in vitro fertilization, oocyte retrieval, fertilization, and blastomere biopsy for identification of unaffected HLA-identical embryos. After delivery, umbilical cord blood from the sibling donor is collected for HCT. The objective of this study was to determine the outcomes of families using PGD therapy for cure of beta-thalassemia and to review the limitations of PGD therapy. Families affected with beta-thalassemia who attempted PGD therapy were retrospectively identified and reviewed for indication, attempted cycles, successful pregnancy, and transplantation outcomes. Eight identified families affected by thalassemia underwent PGD. The diagnosis of their affected children included six cases of beta-thalassemia major and two cases of transfusion-dependent hemoglobin E-beta-thalassemia patients. A total of 14 cycles of PGD were attempted, ranging from one to four attempts per family. Following successful identification of HLA-identical cells, two pregnancies occurred, of which one resulted in engraftment of a beta-thalassemia child. PGD therapy offers the possibility of recruiting a suitable donor for HCT, yet is limited by financial cost due to labor-intensive techniques, low probability of obtaining an HLA-matched unaffected embryo, variable implantation capacity, and significant emotional impact. Improvements in PGD therapy's efficacy and cost will make this a more viable option for affected families.

Experiencing new forms of genetic choice: findings from an ethnographic study of preimplantation genetic diagnosis

Contemporary scientific and clinical knowledges and practices continue to make available new forms of genetic information, and to create new forms of reproductive choice. For example, couples at high risk of passing on a serious genetic condition to their offspring in Britain today have the opportunity to use Preimplantation Genetic Diagnosis (PGD) to select embryos that are unaffected by serious genetic disease. This information assists these couples in making reproductive choices. This article presents an analysis of patients' experiences of making the decision to undertake PGD treatment and of making reproductive choices based on genetic information. We present qualitative interview data from an ethnographic study of PGD based in two British clinics which indicate how these new forms of genetic choice are experienced by patients. Our data suggest that PGD patients make decisions about treatment in a complex way, taking multiple variables into account, and maintaining ongoing assessments of the multiple costs of engaging with PGD. Patients are aware of broader implications of their decisions, at personal, familial, and societal levels, as well as clinical ones. Based on these findings we argue that the ethical and social aspects of PGD are often as innovative as the scientific and medical aspects of this technique, and that in this sense, science cannot be described as "racing ahead" of society.

Preimplantation diagnosis

Preimplantation genetic diagnosis is a valuable addition to the repertoire of reproductive medicine because it gives individuals with a documented history of a genetic disorder the opportunity to begin a wanted pregnancy with little or no fear that they are transmitting this disorder to their offspring. An outstanding example of this is the recent report of PGD being successfully used to avoid the conception of a child that could have inherited a predisposition to early-onset Alzheimer disease. However, if this service becomes embroiled in the detection of conditions having little or nothing to do with health and disease in order to satisfy patient demand or to be a profitable business, its activities will be much more ethically suspect.

Preimplantation genetic diagnosis (PGD), a collaborative activity of clinical genetic departments and IVF centres

Preimplantation genetic diagnosis (PGD) requires the combined efforts of geneticists and workers in the field of reproductive medicine. This was studied on the basis of a questionnaire, sent to 35 members of the PGD Consortium of the European Society of Human Reproduction and Embryology (ESHRE). A reply was obtained from 20 centres. They represent the majority of activities in the field of PGD in the world. It is obvious that many of the activities (in vitro fertilisation, embryo culture and biopsy) take place in IVF units while others (counselling and diagnosis) are the responsibility of genetic diagnostic centres. The distances between both units vary considerably. In all but one centre sex determination is offered. Aneuploidy screening is offered in 13 out of 20 centres. PGD of translocations and other structural chromosome abnormalities is offered in all but one centre. The number of monogenic diseases offered varies considerably. In comparison to prenatal diagnosis PGD is more expensive. The majority of these costs are due to the IVF or ICSI procedure. The charges for PGD vary between about 600 euro and 4000 euro. In 16 out of 20 centres the parents to be must sign an informed consent form.

An analysis of the demand for and cost of preimplantation genetic diagnosis in the United Kingdom

Research in the field of preimplantation genetic diagnosis (PGD) has concentrated on increasing the number of diseases diagnosed, different strategies for single cell analysis and improving efficiency and reliability. Of equal importance are clinical issues such as the demand for and cost of PGD. This study assesses patient awareness of PGD and its potential benefits; additionally the awareness, attitudes and referral patterns of Assisted Conception Units, Regional Genetics Centres and Health Authorities (funding bodies) have been analysed to establish the demand for PGD within the United Kingdom. The licensed units are able to perform 128 cycles of PGD annually, however 256 cases were referred within the last year. It is clear that the currently licensed units operating at their present capacity are unable to meet the demand for PGD in the U.K. Concerns raised by this study include the unequal geographical distribution of PGD services and the lack of a uniform funding policy by Health Authorities. The investment in personnel and technology to establish a PGD service is considered and a costing provided. We estimate an initial investment in the region of 139,000 Pounds with annual running costs of 55,000 Pounds. This information should contribute towards an appropriate allocation of resources at a national level in the U.K.
