Attitudes on the ethics of abortion, sex selection, and selective pregnancy termination among health care professionals, ethicists, and clergy likely to encounter such situations

Fetal reduction for everyone?

Infertility treatments have benefited millions of couples to have their own children; however, the complication of multiple pregnancies with their increased morbidity and mortality has created significant problems. Fetal reduction (FR) was developed to ameliorate these issues. Over 30 years of publications show that FR has been highly successful in substantially reducing both mortality and morbidity. As with most radically new techniques, initial cases were in the "nothing to lose" category. With experience, indications liberalize, and quality of life issues increase as a proportion of cases. Overall risks for twins are not twice as those for singletons, but they are approximately 4- to 5-fold higher. In experienced hands, the combination of genetic testing by CVS followed by FR has made most multiples behave statistically as if they were originally the lower number. The use of microarray analysis to better determine fetal genetic health before deciding on which fetus(es) to keep or reduce further improves pediatric outcomes. With increasing experience and lower average starting numbers, the proportion of FRs to a singleton has increased considerably. Twins to a singleton FR now constitute an increasing proportion of cases performed. Data on such cases show improved outcomes, and we believe FR should be at least discussed and offered to all patients with a dichorionic twin pregnancy or higher. eSET is not a panacea because of the resultant monochorionic twins.

Fetal reduction and twins

Infertility treatments have allowed millions of couples to have their own children, but resultant multiple pregnancies with their increased morbidity and mortality have been a significant complication. Fetal reduction was developed to ameliorate this issue. Over 30 years of publications show that fetal reduction has been highly successful in substantially reducing both mortality and morbidity related to multiple pregnancies. As with most radically new techniques, initial cases were in the "nothing to lose" category. With experience, indications liberalize, and quality of life issues gain relevance. The overall risks of twin pregnancy are not twice that of singleton pregnancy; they are about 4 to 5 times higher. In experienced hands, the combination of genetic testing by chorionic villus sampling followed by fetal reduction has made the outcomes of most multiple pregnancies statistically equivalent to those of pregnancies with lower fetal numbers. Use of microarray analysis to better determine fetal genetic health before deciding on which fetus(es) to keep or reduce further improves pediatric outcomes. With increasing experience and lower average starting numbers, the proportion of fetal reductions to a singleton has increased considerably. Twins to a singleton fetal reductions now constitute an increasing proportion of cases performed. Data on such cases show improved outcomes, and we believe fetal reduction should be at least discussed and offered to all patients with a dichorionic twin pregnancy or higher. With the increasing reliance on elective single-embryo transfers, monochorionic twins, which have much higher complication rates than dichorionic twins, have increased substantially. Furthermore, monochorionic twins cannot be readily and safely reduced, so the adverse perinatal statistics of elective single-embryo transfer are a major setback for good outcomes. Although elective single-embryo transfer is appropriate for some, we believe that for many couples, the transfer of 2 embryos is generally a more rational approach.

Recruitment and retention strategies for expert nurses in abortion care provision

OBJECTIVE(S)

The purpose of this thematic analysis is to describe recruitment, retention and career development strategies for expert nurses in abortion care provision.

STUDY DESIGN

Thematic analysis influenced by grounded theory methods were used to analyze interviews, which examined cognitive, emotional, and behavioral processes associated with how nurses make decisions about participation in abortion care provision. The purposive sample consisted of 16 nurses, who were interviewed between November 2012 and August 2013, who work (or have worked) with women seeking abortions in abortion clinics, emergency departments, labor and delivery units and post anesthesia care units.

RESULTS

Several themes emerged from the broad categories that contribute to successful nurse recruitment, retention, and career development in abortion care provision. All areas were significantly influenced by engagement in leadership activities and professional society membership. The most notable theme specific to recruitment was exposure to abortion through education as a student, or through an employer. Retention is most influenced by flexibility in practice, including: advocating for patients, translating one's skill set, believing that nursing is shared work, and juggling multiple roles. Lastly, providing on the job training opportunities for knowledge and skill advancement best enables career development.

CONCLUSION(S)

Clear mechanisms exist to develop expert nurses in abortion care provision.

IMPLICATIONS

The findings from our study should encourage employers to provide exposure opportunities, develop activities to recruit and retain nurses, and to support career development in abortion care provision. Additionally, future workforce development efforts should include and engage nursing education institutions and employers to design structured support for this trajectory.

Understanding feticide: an analytic review

The medical procedure of 'feticide' has been used in clinical practice since the early 1990s in the UK. The procedure constitutes a sensitive aspect of late termination of pregnancy (TOP), an issue that is in itself contentious. The procedure has attracted attention from academic and policy commentators, but recently the medical profession has expressed some uncertainty with respect to the legal position of live birth following TOP, and professional discretion in providing feticide. To understand the meaning of these comments better, we argue that it is helpful to acknowledge the rhetoric that shapes the academic discourse on feticide. In this paper, we review how feticide has been conceptualised within academic discourse, demonstrating that the concept has multiple meanings, some of which could be considered politically charged. We then consider some examples of the comments made about the legal uncertainties of feticide, highlighting assumptions made about the problematic nature of professional discretion. Ultimately, we suggest that a better understanding of the context of feticide is needed to ensure that future research in this area of health care engages adequately with issues of professional discretion.

Do reduced multiples do better?

Dramatic successes in infertility care have allowed millions of previously fertile women to have their own children. However, an epidemic of multiple pregnancies has resulted, with catastrophic increases in morbidity and mortality, and in the economic costs to society. Multifetal pregnancy reduction (MFPR) has been used to decrease fetal number in the late first trimester and has dramatically improved outcomes. Recent data suggest that pregnancies starting with three or four, and in some cases five fetuses, which are reduced to twins, do as well as starting with twins. Patients with triplets do better reduced to twins. Reduction to a singleton is becoming more common, particularly for women over 40. Combining MFPR with chorionic villus sampling in patients over 30 years of age has enabled couples to maximize the health of the resultant children.

Nurses’ Attitudes Toward Pregnancy Termination in the Labor and Delivery Setting

OBJECTIVE

To examine nurses' attitudes toward pregnancy termination in the labor and delivery setting and the frequency of nurse refusal to care for patients undergoing pregnancy termination.

DESIGN

Nonexperimental, descriptive study.

SETTING

Six central and northern California hospitals, including Level 1, 2, and 3 facilities.

PARTICIPANTS

Seventy-five labor and delivery registered nurses.

METHOD

Anonymous survey with visual analog scales.

RESULTS

Ninety-five percent of the nurses indicated they would agree to care for patients terminating a pregnancy because of fetal demise, 77% would care for patients terminating a fetus with anomalies that were incompatible with life, and 37% would care for patients terminating for serious but nonlethal anomalies, with a significant drop in agreement as gestation advanced. Few nurses would agree to care for patients undergoing termination for sex selection, selective reduction, or personal reasons. Nurses both accepting and refusing patient care assignments were criticized by coworkers.

CONCLUSION

Clear guidelines should be established on how to handle nurse refusal to care for patients terminating pregnancy in advance. Open discussions should be encouraged between staff and management to minimize criticism.

The Experience of Person-Role Conflict in Doctors Expected to Terminate Pregnancies in the South African Public Sector

This study examines the experiences of person-role conflict amongst doctors working in obstetrics and gynaecology with regard to the provision of abortion services in the public sector. Fifteen doctors were interviewed in order to assess their personal experiences and the role forces that were evident, especially in situations where doctors were confronted with the expectation that they terminate pregnancies either on demand or for social reasons. This study explores the role forces that are operating, attitudes towards abortion versus willingness to perform abortions, the potential impact on the quality of service provided, and the personal implications of person-role conflict for the doctors.

Selective reduction

Multifetal pregnancy reduction continues to be controversial. Attitudes about MFPR have not, in our experience, followed a simple "pro-choice/pro-life" dichotomy. As far back as the mid to late 1980s, opinions about the subject were varied. Even then, when much less was known about the subject, opinions did not always parallel the usual pro-choice/theological boundaries. We believe that the real debate over the next 5 to 10 years will not be whether or not MFPR should be performed with triplets or more. The fact is that MFPR does improve those outcomes. A serious debate will emerge over whether or not it is appropriate to offer MFPR routinely for twins, even natural ones, for whom the outcome is commonly considered "good enough." Our data suggest that reduction of twins to a singleton improves the outcome of the remaining fetus. No consensus on appropriateness of routine 2-1 reductions is ever likely to emerge. The ethical issues surrounding MFPR will always be controversial. Over the years, much has been written on the subject. Opinions will always vary from outraged condemnation to complete acceptance. No short paragraph could do justice to the subject other than to state that most proponents do not believe this is a frivolous procedure but do believe in the principle of proportionality ie, therapy to achieve the most good for the least harm). Over the past 15 years, MFPR has become a well-established and integral part of infertility therapy and attempts to deal with the sequelae of aggressive infertility management. In the mid 1980s, the risks and benefits of the procedure could only be guessed. We now have clear and precise data on the risks and benefits of the procedure and an understanding that the risks increase substantially with the starting and finishing number of fetuses in multifetal pregnancies. The collaborative loss rate numbers (ie, 4.5% for triplets, 8% for quadruplets. 11% for quintuplets, and 15% for sextuplets or more) seem reasonable to present to patients for the procedure performed by an experienced operator. Our experiences and anecdotal experiences from other groups suggest that less experienced operators have worse outcomes. Pregnancy loss is not the only poor outcome. The other main issue with which to be concerned is very early premature delivery, where there is an increasing rate of poor outcomes correlated with the starting number. The finishing numbers are also critical, with twins having the best outcomes for cases starting with three or more. Triplets and singletons do not do as well. We hope that MFPR will become obsolete as better control of ovulation agents and assisted reproductive technologies make multifetal pregnancies uncommon.

X-Y sperm selection: fact or fiction?

Selecting the gender of offspring has given rise to various and sometimes amusing stories. But regardless of which prefertilisation technique is used to influence the sex ratio of offspring it must fulfill certain criteria. First of all it must achieve a complete separation of the X and Y bearing sperm in sufficient quantities. Secondly sperm must be viable after separation and capable of fertilising. Sex preselection methods can be divided into two general groups which either separate spermatozoa on the basis of subtle physical or kinetic features or those which rely on distinctive nuclear characteristics unique either to X or Y chromosome bearing sperm. These, in turn, can be divided into in vivo methods designed to produce optimal conditions for fertilisation by either the X or Y bearing sperm, or in vitro sperm separation methods designed to separate X or Y bearing sperm. According to all published data, the different separation techniques have been shown not to be very effective. Only sex selection of spermatozoa by chromatin differences (cell sorting by flow cytometry) has demonstrated a significant enrichment of the X bearing sperm.

Ethical decision-making in prenatal diagnosis and termination of pregnancy: a qualitative survey among physicians and midwives

OBJECTIVES

This study was aimed at exploring the conflicts and ethical problems experienced by professionals involved in prenatal diagnosis and termination of pregnancy (TOP) in order to improve the understanding of decision-making processes and medical practices in the field of prenatal diagnosis.

METHODS

Qualitative study with in-depth tape-recorded interviews conducted in three tertiary care maternity units in France, between May 1999 and March 2000. All full-time obstetricians and half of the full-time midwives were contacted. Seventeen obstetricians and 30 midwives participated (three refusals, five missing). Interviews were transcribed and analysed successively by two different researchers.

RESULTS

All respondents stated that prenatal diagnosis and TOP raised important ethical dilemmas, the most frequent being request for abortion in case of minor anomalies. They pointed out the inability of our society to appropriately care for disabled children and the risk of eugenic pressures. The decisions and practices in prenatal diagnosis should be debated throughout society. All respondents reported that their unit did not have protocols for deciding when a TOP was justifiable. The transmission of information to the women appeared to be a problematic area. Moral conflicts and emotional distress were frequently expressed, especially by midwives who mentioned the need for more discussions and support groups in their department.

CONCLUSION

Health professionals involved in prenatal diagnosis face complex ethical dilemmas which raise important personal conflicts. A need for more resources for counselling women and for open debate about the consequences of the current practices clearly emerged.

Procedural risks versus theology: chorionic villus sampling for Orthodox Jews at less than 8 weeks' gestation

OBJECTIVE

According to Orthodox Jewish law, abortion is only permitted before 40 days post conception. This evaluation was performed to determine the feasibility and safety of performing chorionic villus sampling (CVS) at 7 to 8 weeks' gestation so that genetic results would be useful for these patients.

STUDY DESIGN

We evaluated a sequential series of 82 Orthodox Jewish patients who chose CVS at <63 days' gestation. Outcome measures included procedure success rates, laboratory success rates, pregnancy outcomes, and complications.

RESULTS

CVS was successful in all cases. Ninety-one percent were performed transcervically, with 30% requiring 2 or more insertions. Abnormal results were found in 16 (20%). Of 61 cases with normal genetic and ultrasound results, spontaneous losses at less than 28 weeks occurred in 3 (5%). These rates are higher than the 2.3% loss rate and the 1.2% multiple insertion rate seen at our center when sampling is performed at the usual gestational ages of 10 to 12 weeks. One baby had a severe limb reduction defect (1.6%).

CONCLUSION

In very experienced hands, CVS can be safely and reliably performed at very early gestational ages. The ability to obtain an early diagnosis may be associated with increased but acceptable complication rates, including a 1% to 2% risk of limb reduction defects. There are patients for whom the usual paradigms do not suffice, and obtaining an early disgnosis provides them the opportunity to trade increased risks for reproductive choice. The ethical issues are complex, but such decisions can be supported by extensive and detailed informed consent.

Prenatal intervention: ethical considerations for life-threatening and non-life-threatening anomalies

Ethical issues in maternal-fetal surgery require special consideration because of the often-conflicting interests of the mother and fetus. Over the past 2 decades an ethical framework for fetal therapy and maternal-fetal surgery has been developed. This framework continues to evolve as new procedures are developed and new controversies arise. The most recent ethical challenge has been the application of maternal-fetal surgery to nonlethal fetal anomalies, specifically, repair of fetal myelomeningocele. Such procedures require early evaluation by randomized clinical trials to avoid premature dissemination of unproven therapy. These trials currently are being initiated, and the ethical framework for proceeding requires careful consideration. This review will summarize the current ethical issues and controversies in maternal-fetal surgery in the context of these new developments.

Sex selection in practice among Hong Kong Chinese

The aim of this study is to identify factor(s) influencing imbalance in the sex distribution of children (more children of the same sex) of the multiparous women attending an antenatal clinic in Hong Kong. A retrospective study was carried out to compare the expected and observed sex ratios of babies born to women with one previous live birth and women with two. All singleton pregnant women of parities 1 and 2 delivering after 22 weeks of gestation, between 1 July 1996 and 30 June 1998, were included. A total of 2604 women of parity 1 and 752 women of parity 2 were included. The sexes of the children of parity 1 women and the sex distribution of their newborns were consistent with the predicted value. The parity 2 women were more likely to have third children if their previous children were of the same sex (p-value < 0.001). This implies that the parity 2 women attending our antenatal clinic had third pregnancies because of social, economical or environmental reasons. Our parity 2 women with two daughters were more likely to have sons (p < 0.05). Thus, biological or parental factors were unlikely to be important in influencing the sex of the newborn. This suggested that sex selection or sex-selective abortion might be practiced among Hong Kong Chinese women.

Regional trend variations in infant mortality due to perinatal conditions in the Netherlands

CONDENSATION

In the Netherlands, regional variations in trends in infant mortality due to perinatal conditions (1984-1994) exist, which could not be explained by health care characteristics (i.e., place or supervision of delivery and the presence of specialised neonatal care). The only sociodemographic factor that showed a consistent correlation with mortality was the percentage of Roman Catholic inhabitants of a region.

OBJECTIVE

To describe and explain regional variations in trends in infant mortality due to perinatal conditions.

STUDY DESIGN

A mixed (geographical and temporal) ecological design has been used. Infant mortality due to perinatal conditions was defined as mortality in the first year of life caused by diseases of the newborn period (chapter XV of the ICD-9). Trends in sex-adjusted mortality for the period 1984-1994 as well as mortality levels at the start of this period were calculated using log linear regression. Linear regression was used to examine the association between mortality trends and starting levels on the one hand and both health care and sociodemographic factors on the other.

RESULTS

Statistically significant variations in mortality trends were found between regions. The trends in the two Southern regions were found to deviate significantly from the national trend. No strong association was found between mortality and each of the health care factors (i.e. place and/or supervision of delivery and the presence of specialised neonatal care). The only sociodemographic factor that showed consistent results was the percentage of Roman Catholic inhabitants of a region: A higher percentage in 1985 was associated with a higher mortality in 1985 and a stronger mortality decline during the period 1984-1994. This association could not be explained by parity or the age of the mother.

CONCLUSIONS

Regional differences in trends in infant mortality due to perinatal conditions in the Netherlands could not be explained by variations in health care factors. This is an important finding as the Dutch system of obstetric care, that includes a considerable number of home deliveries, has been subject to much debate. Further research that includes other causes of death and determinants is needed to unravel the causes of the trend variations.

Ethics and assisted reproduction

In vitro fertilization and assisted reproductive technology have made great progress during the last 20 years. Genetic material donation, human embryo cryopreservation, selective embryo reduction, preimplantation genetic diagnosis and surrogacy are currently practiced in many countries. On the other hand, embryo research is practiced only in a small number of nations, whereas human cloning has thus far been universally condemned. The rapid evolution and progress of all these techniques of assisted reproduction has revealed certain ethical issues that have to be addressed.

Family physicians' perspectives on genetics and the human genome project

The objective of the study was to determine family physicians' attitudes and beliefs about human genetics research and the human genome project (HGP). The design of the study involved qualitative, semi-structured interviews. Primary variables of interest included family physicians' training; their attitudes about the HGP; requests for genetics counseling; and their approaches to counseling requests. The setting was a medium-sized, Midwest, US city. The participants were 16 university-affiliated, community-based family physicians. For contents analysis, we used a coding scheme to identify illustrative themes and subthemes. While most of the family physicians reported familiarity with genetics and the HGP, and experiences with counseling requests, nearly all (15) reported little training in genetics counseling. Four major themes were identified: 1) impact on clinical care; 2) educational issues relevant to genetics and the HGP; 3) ethical concerns; and 4) family medicine responsibilities. These family physicians do not perceive genetics as having a substantial impact on their practice, but do expect major clinical changes in the future. Many feel there have been inadequate educational opportunities to learn about genetics, and some indicate reluctance to invest in self-education until genetic problems become more clinically relevant. These practitioners envision a role for family medicine the specialty to shape priorities in genetics research.

Stability of attitudes regarding physician-assisted suicide and euthanasia among oncology patients, physicians, and the general public

PURPOSE

Attitudes regarding the ethics of physician-assisted suicide (PAS) and euthanasia have been examined in many cross-sectional studies. Stability of these attitudes has not been studied, and this is important in informing the dialog on PAS in this country. We evaluated the stability of attitudes regarding euthanasia and PAS among three cohorts.

METHODS

Subjects included 593 respondents: 111 oncology patients, 324 oncologists, and 158 members of the general public. We conducted initial and follow-up interviews separated by 6 to 12 months by telephone, regarding acceptance of PAS and euthanasia in four different clinical vignettes.

RESULTS

The proportion of respondents with stable responses to vignettes ranged from 69.2% to 94.8%. In comparison to patients and the general public, physicians had less stable responses concerning the PAS pain vignette (69.1% v 80.8%; P =.001) and more stable responses for all euthanasia vignettes (P <.001) except for pain. Over time, physicians were significantly more likely to change toward opposing PAS and euthanasia in all vignettes (P <.05). Characteristics previously associated with attitudes regarding PAS and euthanasia, such as Roman Catholic religion, were not predictive of stability.

CONCLUSION

Up to one third of participants changed their attitudes regarding the ethical acceptability of PAS and euthanasia in their follow-up interview. This lack of consistency mandates careful interpretation of referendums and requests for physician-assisted suicide. Furthermore, in this study, we found that physicians are becoming increasingly opposed to PAS and euthanasia. The growing disparity between physicians and patients regarding the role of these practices is large enough to suggest possible conflicts in the delivery of end-of-life care.

Ethical issues in reproductive genetics

Because of technological developments in reproductive genetics, couples now have many options not available a decade ago. Some developments are controversial and deeply divide our society. This article examines some of these issues and establishes guidelines of approach.

Multifetal pregnancy reduction: a review of the world results for the period 1993-1996

The objective of this work was to evaluate the outcome of multifetal pregnancy reduction and to provide an analysis of the ethical dilemmas associated with its application. The study design was based on data on over 1400 completed pregnancies that underwent multifetal pregnancy reduction as reported in the world literature during 1993-1996. The results were: A total of 1453 completed cases of multifetal pregnancy reduction are presented. The total survival rate was estimated to be 87.7%, resulting in a total pregnancy loss rate of 12.3%. The lowest survival rate is found to be in higher-order pregnancies of five or more fetuses (75.2%), whereas pregnancy loss rate seems to be similar for quadruplets, triplets and twins that underwent reduction (11.3%, 8.3% and 13.6%, respectively). A 33.3% of the total pregnancy loss rate occurred within four weeks from the procedure, whereas 66.7% occurred after the four weeks but at 24 weeks of gestation or earlier. The mean gestational age at delivery was estimated to be 33 weeks for pregnancies reduced to triplets, 35.8 weeks for those reduced to twins and 36.9 weeks for singletons, with 5% delivering at less than 28 weeks and 9.6% at 29-32 weeks. We conclude that multifetal pregnancy reduction has been established as an efficient and safe way to improve outcome of multifetal gestations, especially those with four or more fetuses and likely of triplets. As the experience from the procedure increases, it seems that reduction of triplets to twins can be offered to patients with satisfactory results. The reduction to singletons has not yet been established and is being performed only when medical indications exist. Prenatal genetic diagnosis should become an integral part of counselling on multiple pregnancy. Physicians should take whenever possible measures designed to prevent high multiple birth pregnancies. We also note that although multifetal pregnancy reduction improves significantly the outcome of multiple pregnancies, several ethical dilemmas arising from its application are still under dispute.

Three ethically justified indications for selective termination in multifetal pregnancy: a practical and comprehensive management strategy

The authors provide an ethical justification for three indications for performing selective termination of multi-fetal pregnancies. These indications are (1) achieving a pregnancy that results in a live birth or one or more infants with minimal neonatal morbidity and mortality, (2) achieving a pregnancy that results in a live birth of one or more infants without antenatally detected anomalies, and (3) achieving a pregnancy that results in a singleton live birth. This ethical justification is based on two basic approaches to obstetric ethics that emphasize that these indications must be established on the basis of informed consent. The authors underscore the importance of matters of private conscience and demonstrate the consistency of ethical justification with existing public policy in the United States.

Outcome of triplet pregnancies after assisted reproductive techniques: how frequent are the vanishing embryos?

OBJECTIVE

To assess the incidence of spontaneous embryo reduction as well as the obstetric and neonatal outcome of triplet gestations after assisted reproductive techniques (ART).

METHODS

We analyzed the spontaneous outcome of 38 pregnancies in which three gestational sacs were identified with vaginal ultrasound between 21 and 28 days after ART. Weekly follow-up visits were scheduled during the first trimester until referral to a high-risk obstetrician. After delivery, each patient was interviewed individually and, if necessary, the obstetrician was contacted.

RESULTS

The triplets delivery rate was 47.4%, whereas 31.6% delivered twins, 18.4% delivered singletons, and only one patient miscarried all three cases (2.6%). Finding three fetal heart beats was associated with a triplet delivery rate of 69.2%, a twin incidence of 19.2%, and a singleton birth rate of 11.6%. Embryo resorptions were observed mainly during the first 7 weeks of gestation and did not occur beyond the 14th week. The mean gestational age at delivery and neonatal birth weight were significantly lower among triplets (32.8 weeks and 1,740 g versus 35.3 weeks and 2,352 g in twins and 39.1 weeks and 3,122 g for singletons). Triplets had a 100% prematurity and cesarean section rate compared with 67% and 75% in twins and 0% and 43% in singletons, respectively. Hospitalization at the Neonatal Intensive Care Unit was required in 83% of newborn triplets, 29% of twins, and 0% of singletons, with a mean stay of 34 and 21 days for triplets and twins, respectively. One stillbirth and no neonatal deaths were reported, with an overall perinatal mortality rate of 11.9 per 1,000.

CONCLUSIONS

Spontaneously, approximately 50% of triplet pregnancies will experience at least one embryo resorption. The ongoing triplets demand a complex and more expensive perinatal management, a strong argument to consider limiting the number of oocytes-embryos transferred in ART.

Sex-selective abortion: a relational approach

A critical application of Ruddick's model of maternal thinking is the best way to grapple with the ethical dilemmas posed by sex-selective abortion which I view as a "moral mistake." Chief among these is the need to be sensitive to local cultural practices in countries where sex-selective abortion is prevalent, while simultaneously developing consistent international standards to deal with the dangers posed by the use of sex-selective abortion to eliminate female fetuses.

Multifetal reduction of triplets to twins improves perinatal outcome

OBJECTIVE

Our purpose was to compare the perinatal outcome of triplet pregnancies reduced to twins with the outcomes of continuing triplet pregnancies and twin pregnancies.

STUDY DESIGN

Pregnancy outcomes of triplet pregnancies reduced to twins delivered between July 1988 and July 1992 were compared with pregnancy outcomes of continuing triplet and twin pregnancies delivered over the same time period.

RESULTS

The mean gestational age at delivery for the reduced triplets was 35.6 weeks, compared with 31.2 weeks in the nonreduced triplets (p = 0.002). The perinatal mortality rate was 30 per 1000 births in the reduction group and 210 per 1000 births in the nonreduced triplets (p < 0.0001). There were no statistically significant differences between the reduced and nonreduced twins.

CONCLUSION

Multifetal pregnancy reduction of triplets to twins yields an improved perinatal outcome compared with nonreduced triplets and a similar outcome compared with nonreduced twins.

Effects of selective reduction in triplet gestation: a comparative study of 80 cases managed with or without this procedure

OBJECTIVE

To evaluate the effect of selective termination in triplet pregnancies.

DESIGN

Comparative, prospective, nonrandomized study.

SETTING

All 80 pregnancies were managed in a single tertiary center by the same obstetrical team.

PATIENTS

Eighty women with triplet pregnancies were divided into two groups: group I consisted of 48 women who wished to continue their pregnancies without reduction; in group II were 32 women who choose reduction generally to obtain twins.

INTERVENTIONS

Selective terminations were performed after an average term of 9.6 weeks of gestation by transcervical or transabdominal approaches.

MAIN OUTCOME MEASUREMENTS

The rate of miscarriage and prematurity, fetal growth, perinatal morbidity and mortality, and maternal complications in the two groups.

RESULTS

Prematurity was lower in reduced pregnancies (95.5% in triplets versus 53.5%), especially between 24 to 32 weeks' gestation where prematurity was reduced by half. Birth weight was > 450 g higher in the reduced group. The perinatal mortality rate was lower for reduced pregnancies, but this difference was not statistically significant. Five life-threatening maternal complications occurred in triplets, with none in the reduced group.

CONCLUSIONS

Selective terminations are effective in decreasing the rate of prematurity, improving fetal growth, and avoiding maternal complications. The procedure thus could be used in triplet gestations. The ultimate decision should be taken by the couple who must be well informed of the risks of the procedure before deciding.

Triplets and quadruplets born in Victoria between 1982 and 1990. The impact of IVF and GIFT on rising birthrates

OBJECTIVES

To examine the perinatal characteristics of all higher order multiple births (133 sets of triplets and six sets of quadruplets) in the State of Victoria between 1982 and 1990. To compare the rising higher order multiple birth rates in Victoria with those in the other States of Australia, and to assess the impact of in-vitro fertilisation (IVF) and gamete intrafallopian transfer (GIFT) on these rising birth rates.

DESIGN

Retrospective review of all higher order multiple births registered in Victoria and other States of Australia between 1982 and 1990, and in particular those resulting from IVF and GIFT.

DATA SOURCES

Victorian Perinatal Data Collection Unit, Australian Bureau of Statistics, National Perinatal Statistics Unit, data from Victorian IVF and GIFT units.

MAIN OUTCOME MEASURES

Higher order multiple birth rates and perinatal mortality rates.

RESULTS

The higher order multiple birth rates in Victoria rose from 3.5 per 10,000 in 1982 to 10.9 per 10,000 in 1990. The average perinatal mortality rates for the Victorian triplets and quadruplets born during this period were 10.8% and 25.0%, respectively. The rates of caesarean section were 70% and 83%; the proportions of deliveries in level III hospitals, 75% and 100%; and the mean maternal lengths of stay in hospital, 32 and 57 days, respectively. Endotracheal intubation was performed at birth in 18.5% of all infants. The proportions of triplet and quadruplet pregnancies in Victoria owing to IVF and GIFT rose during this period, reaching a peak of 42% in 1990. In the other States, the birth rates for higher order multiples increased at 1.8 times the rate observed for Victoria, with IVF and GIFT contributing to an estimated 43% of these conceptions between 1985 and 1989.

CONCLUSION

Restrictions on the numbers of embryos/oocytes transferred during IVF and GIFT should reduce the frequency of higher order multiple births.

Health policy dilemmas related to high technology infertility services

As cost containment in health care becomes an important concern, the costs and benefits of specific health care services will be more closely examined. The costs and benefits of one type of health care, high technology infertility services, are explored in this paper. These services may be particularly susceptible to cost containment since they are costly, raise ethical issues, and because they currently are provided to healthy individuals not experiencing life-threatening illness who can afford them.
