Caesarean scar ectopic pregnancy: a case series and case report to highlight the experience in regional New Zealand.

AIMS: To evaluate the approach to diagnosis and management of caesarean scar pregnancy (CSP) at a regional New Zealand hospital. METHODS: A retrospective case series of ten patients between June 2015 and May 2020. The data review included demographic information, ultrasound findings, human chorionic gonadotropin (HCG) levels, primary and subsequent treatment, outcomes and complications. RESULTS: Nine women were diagnosed with CSP at a gestational age between four and ten weeks. One of these women was treated twice for two separate CSP within the study period. Treatment varied according to clinical presentation, HCG levels, gestational age, ultrasound findings and patient preference. Two thirds of women were successfully treated with primary management, with one third requiring multiple treatment modalities. We report one severe life-threatening haemorrhage and three cases resulting in hysterectomy. We also show a disproportionate number of Maori women presenting with CSP. CONCLUSION: We present a series of ten cases of CSP and demonstrate similar challenges in regional New Zealand to those reported elsewhere. Management is heterogeneous with little guidance from the literature, and primary management was successful in seven out of ten cases. We report a disproportionately high number of cases in Maori women. Our results would support the development of a national register for caesarean scar pregnancy to improve diagnosis and management across New Zealand.

Increased incidence of ectopic pregnancy after in vitro fertilization in women with decreased ovarian reserve.

The incidence of ectopic pregnancy after assisted reproductive technology is increased approximately 2.5-5-fold compared with natural conceptions.Strategies were used to decrease the incidence of ectopic pregnancy, but ectopic pregnancy still occurs. In the present study, women were selected with decreased ovarian reserve (defined as FSH > 10 IU/L) aged 20 to 38 years who underwent IVF-ET between 2009 and 2014. These 2,061 women were age-matched with an equal number of women with normal ovarian reserve (defined as FSH ≤ 10 IU/L). During cycles following fresh embryo transfer, 93 patients were diagnosed with ectopic pregnancy. The incidence of ectopic pregnancy in clinical pregnancies was significantly higher in the decreased ovarian reserve than in the normal ovarian reserve group (5.51% vs. 2.99%). After adjusting for confounding factors, the incidence of ectopic pregnancy was significantly associated with decreased ovarian reserve. Our results showed that decreased ovarian reserve is an independent risk factor for ectopic pregnancy after in vitro fertilization-embryo transfer.

Disparities in receipt of a laparoscopic operation for ectopic pregnancy among TRICARE beneficiaries.

BACKGROUND: Racial disparities in receipt of a laparoscopic operation for ectopic pregnancy are attributed to inequalities in access to care. This study sought to determine if racial disparities in laparoscopic operation for ectopic pregnancy exist among a universally insured population. METHODS: Using 2006-2010 TRICARE (insurance for members of the United States Armed Services and their dependents) data, patients who received a laparoscopic operation or laparotomy for ectopic pregnancy were stratified into direct/military or purchased/civilian system of care. Odds of receipt of a laparoscopic operation in each racial group were compared adjusting for patient demographics, system of care, and severity of ectopic pregnancy. RESULTS: Among 3,041 patients in the study sample, 1,878 (61.7%) received laparotomy and 1,163 (38.2%) received a laparoscopic operation within 30 days of diagnosis. Overall, 42.4% of white women received a laparoscopic operation compared with 33.1% of Asian women and 34.9% of black women (P < .001). On multivariable analysis, black women had a 33% lesser odds of receiving a laparoscopic operation (odds ratio: 0.67; confidence interval: 0.55-0.83) compared with white women. These disparities were absent within direct care (odds ratio: 0.93; confidence interval: 0.71-1.21) but were present within purchased care (odds ratio: 0.54; confidence interval: 0.40-0.73). CONCLUSION: Racial minority patients are less likely to receive a laparoscopic operation for ectopic pregnancy despite universal insurance coverage within civilian/purchased care. Further work is warranted to better understand the factors other than insurance access that may contribute to racial disparities in selection of operative approach.

Fragmentation of Care in Ectopic Pregnancy.

OBJECTIVES: Ectopic pregnancy is an important cause of maternal morbidity and mortality. Women who experience fragmented care may undergo unnecessary delays to diagnosis and treatment. Based on ectopic pregnancy cases observed in clinical practice that raised our concern about fragmentation of care, we designed an exploratory study to describe the number, characteristics, and outcomes of fragmented care among patients with ectopic pregnancy at one urban academic hospital. METHODS: Chart review with descriptive statistics. Fragmented care was defined as a patient being evaluated at an outside facility for possible ectopic pregnancy and transferred, referred, or discharged before receiving care at the study institution. RESULTS: Of 191 women seen for possible or definite ectopic pregnancy during the study period, 42 (22 %) met the study definition of fragmented care. The study was under-powered to observe statistically significant differences across groups, but we found concerning, non-significant trends: patients with fragmented care were more likely to be Medicaid recipients (65.9 vs. 58.8 %) and to experience a complication (23.8 vs. 18.1 %) compared to those with non-fragmented care. Most patients (n = 37) received no identifiable treatment prior to transfer and arrived to the study hospital with no communication to the receiving hospital from the outside provider (n = 34). Nine patients (21 %) presented with ruptured ectopic pregnancies. The fragmentation we observed in our study may contribute to previously identified socio-economic disparities in ectopic pregnancy outcomes. CONCLUSION: If future research confirms these findings, health information exchanges and regional coordination of care may be important strategies for reducing maternal mortality.

Ectopic pregnancy among American Indian and Alaska Native women, 2002-2009.

To examine rates of ectopic pregnancy (EP) among American Indian and Alaska Native (AI/AN) women aged 15-44 years seeking care at Indian Health Service (IHS), Tribal, and urban Indian health facilities during 2002-2009. We used 2002-2009 inpatient and outpatient data from the IHS National Patient Information Reporting System to identify EP-associated visits and obtain the number of pregnancies among AI/AN women. Repeat visits for the same EP were determined by calculating the interval between visits; if more than 90 days between visits, the visit was considered related to a new EP. We identified 229,986 pregnancies among AI/AN women 15-44 years receiving care at IHS-affiliated facilities during 2002-2009. Of these, 2,406 (1.05 %) were coded as EPs, corresponding to an average annual rate of 10.5 per 1,000 pregnancies. The EP rate among AI/AN women was lowest in the 15-19 years age group (5.5 EPs per 1,000 pregnancies) and highest among 35-39 year olds (18.7 EPs per 1,000 pregnancies). EP rates varied by geographic region, ranging between 6.9 and 24.4 per 1,000 pregnancies in the Northern Plains East and the East region, respectively. The percentage of ectopic pregnancies found among AI/AN women is within the national 1-2 % range. We found relatively stable annual rates of EP among AI/AN women receiving care at IHS-affiliated facilities during 2002-2009, but considerable variation by age group and geographic region. Coupling timely diagnosis and management with public health interventions focused on tobacco use and sexually transmitted diseases may provide opportunities for reducing EP and EP-associated complications among AI/AN women.

Ectopic pregnancy rates and racial disparities in the Medicaid population, 2004-2008.

OBJECTIVE: To assess 2004-2008 ectopic pregnancy rates among Medicaid recipients in 14 states and 2000-2008 time trends in three states and to identify differences in rate by race/ethnicity. DESIGN: Secondary analysis of Medicaid administrative claims data. SETTING: Not applicable. PATIENT(S): Women ages 15-44 enrolled in Medicaid in Arizona, California, Colorado, Florida, Illinois, Indiana, Iowa, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, New York, or Texas in 2004-2008 (n = 19,135,106) and in California, Illinois, and New York in 2000-2003. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Number of ectopic pregnancies divided by the number of total pregnancies (spontaneous abortions, induced abortions, ectopic pregnancies, and all births). RESULT(S): The 2004-2008 Medicaid ectopic pregnancy rate for all 14 states combined was 1.40% of all reported pregnancies. Adjusted for age, the rate was 1.47%. Ectopic pregnancy incidence was 2.3 per 1,000 woman-years. In states for which longer term data were available (California, Illinois, and New York), the rate declined significantly in 2000-2008. In all 14 states, black women were more likely to experience an ectopic pregnancy compared with whites (relative risk, 1.46; 95% confidence interval, 1.45-1.47). CONCLUSION(S): Ectopic pregnancy remains an important health risk for women enrolled in Medicaid. Black women are at consistently higher risk than whites.

Ectopic pregnancy, active component, U.S. Armed Forces, 2002-2011.

Ectopic pregnancy (EP) is a rare adverse outcome in which a fertilized egg implants and develops outside of the uterus. Life-threatening cases of EP among deployed U.S. service members have been described. During 2002- 2011, among active component females younger than 49, 1,245 EPs were diagnosed and treated as indicated by diagnostic and procedure codes recorded in electronic medical records. Annual numbers of EPs ranged from 91 to 151. During the period EP affected 0.64 percent of all pregnancies, with higher proportions among servicewomen in their 30s and of black, non-Hispanic race/ ethnicity. As compared with civilians, service members had the same percentage of pregnancies that were ectopic but had lower proportions of EPs that were treated medically (with methotrexate) rather than surgically.

How and when human chorionic gonadotropin curves in women with an ectopic pregnancy mimic other outcomes: differences by race and ethnicity.

OBJECTIVE: To investigate the hCG profiles in a diverse patient group with ectopic pregnancy (EP) and to understand when they may mimic the curves of an intrauterine pregnancy (IUP) or spontaneous abortion (SAB). DESIGN: Retrospective cohort study. SETTING: Three university hospitals. PATIENT(S): One hundred seventy-nine women with symptomatic pregnancy of unknown location. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Slope of log hCG; days and visits to final diagnosis. RESULT(S): Of women with an EP, 60% initially exhibited an increase in hCG values, with a median slope of 32% increase in 2 days; 40% of subjects initially had an hCG decrease, with the median slope calculated as a 15% decline in 2 days. In total, the hCG curves in 27% of women diagnosed with EP resembled that of a growing IUP or SAB. Of the EP hCG curves, 16% demonstrated a change in the direction of the slope of the curve. This was more common in African Americans and less evident in Hispanics. Furthermore, it was associated with more clinical visits and days until final diagnosis. CONCLUSION(S): The rate of change in serial hCG values can be used to distinguish EP from an IUP or SAB in only 73% of cases. The number of women who had a change in direction of serial hCG values was associated with race and ethnicity.

Chlamydia trachomatis trends in the United States among persons 14 to 39 years of age, 1999-2008.

BACKGROUND: We report the first population-based assessment of national trends in chlamydia prevalence in the United States. METHODS: We investigated trends in chlamydia prevalence in representative samples of the U.S. population aged 14 to 39 years using data from five 2-year survey cycles of the National Health and Nutrition Examination Survey from 1999 to 2008. Prevalence estimates and 95% confidence intervals (CI) are reported stratified by age, gender, and race/ethnicity. Percent change in prevalence over this time period was estimated from regression models. RESULTS: In the 2007-2008 cycle, chlamydia prevalence among participants aged 14 to 39 years was 1.6% (95% CI: 1.1%-2.4%). Prevalence was higher among females (2.2%, 95% CI: 1.4%-3.4%) than males (1.1%, 95% CI: 0.7%-1.7%). Prevalence among non-Hispanic black persons was 6.7% (95% CI: 4.6%-9.9%) and was 2.5% (95% CI: 1.6%-3.8%) among adolescents aged 14 to 19 years. Over the five 2-year cycles, there was an estimated 40% reduction (95% CI: 8%-61%) in prevalence among participants aged 14 to 39 years. Decreases in prevalence were notable in men (53% reduction, 95% CI: 19%-72%), adolescents aged 14 to 19 years (48% reduction, 95% CI: 11%-70%), and adolescent non-Hispanic black persons (45%, reduction, 95% CI: 4%-70%). There was no change in prevalence among females aged 14 to 25 years, the population targeted for routine annual screening. CONCLUSIONS: On the basis of population estimates of chlamydia prevalence, the overall chlamydia burden in the United States decreased from 1999 to 2008. However, there remains a need to reduce prevalence in populations most at risk and to reduce racial disparities.

Race, socioeconomic status, and response to methotrexate treatment of ectopic pregnancy in an urban population.

On the basis of the documented racial disparities in ectopic pregnancy incidence and mortality we hypothesized that African-American women with ectopic pregnancy would be more likely than white women to have treatment failure with methotrexate. In this retrospective cohort study, a racial disparity in methotrexate effectiveness was not found, but a significant relationship between low socioeconomic status and methotrexate failure was demonstrated.

Country of birth and hospitalization for pelvic inflammatory disease, ectopic pregnancy, endometriosis, and infertility: a nationwide study of 2 million women in Sweden.

OBJECTIVE: To examine the association between country of birth and hospitalization for pelvic inflammatory disease (PID), ectopic pregnancy (EP), endometriosis, and infertility. DESIGN: Follow-up study. SETTING: Sweden. PARTICIPANT(S): A total of 2,170,177 women living in Sweden at some point between 1990 and 2004, categorized into 10 different groups according to country of birth. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Hospitalization for PID, EP, endometriosis, and infertility. RESULTS: For PID and infertility, all groups of foreign-born women exhibited significantly increased risks compared with Swedish-born women. The highest risks of PID were found among women from southern Europe, Eritrea/Ethiopia/Somalia, and other African countries, whereas the highest risks of infertility were found among women from Middle Eastern countries, other Asian countries, and other African countries. Compared with PID and infertility, country of birth was less associated with endometriosis and EP, although some differences were found. All relative risks were adjusted for age, time period, and the women's socioeconomic status. CONCLUSION(S): Even in a country like Sweden, which offers publicly financed treatment for infertility, differences based on country of birth exist. Although data on partners' income were not available to us, it is possible that other factors besides socioeconomic factors are present in the etiology of female health problems related to infertility.

Multi-cultural surveillance for ectopic pregnancy: California 1991-2000.

BACKGROUND: National surveillance for ectopic pregnancy (EP), the primary cause of maternal death in the first trimester, began in 1970. EP rates peeked during the late 1980s and have been highest for African Americans. However, limited reports on EP rates exist for other racial/ethnic groups. OBJECTIVES: To report state-level, multicultural trends in EP rates from 1991 to 2000. METHODS: Secondary data analysis of the California hospital discharge database collected by the Office of Statewide Health Planning and Development by using codes 633.0-633.9, from the International Classification of Diseases, Ninth Revision. EP rates are reported per 1000 pregnancies. RESULTS: From 1991 to 2000, 62,839 EP were reported in California. Mean EP rate was 11.2/1000, decreased from 15/1000 to 9.3/1000, and varied significantly by race/ethnicity and age. EP rates were highest among African Americans (25/1000) and lowest among Hispanics (7.7/1000); African Americans had higher odds of having EP relative to non-Hispanic Whites (odds ratio [OR] 2.14, 95% confidence interval [CI] 2.09-2.19). Women 35-44 years of age had the highest EP rates (17.6/1000) and higher odds of having EP compared to other age groups (OR 2.45, 95% CI 2.39-2.50). The highest rate of EP was found among African Americans 35-44 years of age (43.1/1000). CONCLUSIONS: The study showed declining EP rates in California for all groups but highlights disparities in EP rates and the attenuated rate of decline for African Americans, which places them at highest risk of death in the first trimester. This study demonstrates the usefulness of analyzing state-level data that may differ from aggregated national data when studying culturally diverse populations.

Barriers to health care and protocol-based treatment of ectopic pregnancy.

OBJECTIVE: To evaluate whether treatment provided for ectopic pregnancies was different for patients with identified barriers to health care, including ethnicity, lack of insurance, distance from the treating facility that provides services and undocumented residency, at an institution that utilizes a protocol-based algorithm for treatment of ectopic pregnancies. STUDY DESIGN: Charts of 401 patients who were diagnosed with ectopic pregnancy from January 1, 1993, through December 31, 1998, were reviewed to compare the use of medical treatment using methotrexate versus surgical treatment. Data were analyzed with respect to patient ethnicity, socioeconomic status (including insurance status and possession of a social security card [a proxy for legal residency status]), residence inside or outside the county of the treating facility, patient presentation and treatment outcomes. RESULTS: There was no difference in treatment modality or success of primary treatment for ectopic pregnancies between groups regardless of ethnicity, health care insurance, residence outside the county the treating facility was located in or possession of a social security number. CONCLUSION: The treatment of ectopic pregnancies at the University of New Mexico Health Sciences Center is consistent across ethnic and socioeconomic populations. A well-designed treatment protocol may help provide evidenced-based, consistent treatment for patients requiring care who also have identified barriers to medical and surgical treatment.

Sudden death: ectopic pregnancy mortality.

OBJECTIVE: To describe the trends in ectopic pregnancy mortality in Michigan from 1985 through 1999 and compare to those of previous time periods. METHODS: We reviewed all cases of maternal mortality from ectopic pregnancy in Michigan from 1985 through 1999. We extracted data from death certificates, hospital inpatient and emergency department records, medical examiner autopsy reports, and reviews by the Michigan Maternal Mortality Study. The Health Data Development Section of the Michigan Department of Community Health provided data on live births and maternal deaths RESULTS: Of the 268 pregnancy-related deaths, 16 (6%) were caused by complications of ectopic pregnancy. Mean age at death was 27 (+/- 6) years. Thirteen deaths were to African-American women and 3 were to white women (P < .01). African-American women had an ectopic mortality ratio 18 times higher than white women (3.25/100,000 live births, compared with 0.18/100,000) Three cases of pregnancy-related death due to complications of ectopic pregnancy were considered preventable, and 2 others were of unknown preventability. CONCLUSION: Ectopic pregnancy treatment has changed in the last 20 years coincident with a decrease in maternal mortality from ectopic pregnancy. Sudden death was the presenting scenario in 75% of nonpreventable ectopic deaths, an increase from previous analyses. A large racial disparity is apparent. Ideally, pregnancy care should start as soon as possible after the first missed menses; however, systemwide changes are needed to create a new norm promoting early access to pregnancy care and promoting education and testing to rule out pregnancy abnormalities. LEVEL OF EVIDENCE: II-2

Ectopic pregnancy: a nursing approach to excess risk among minority women.

Ectopic pregnancy rates have quadrupled during the last decade. Although maternal mortality has been reduced for white women, largely because of rapid pregnancy testing and improved ultrasonography, the death rate for minority women is almost twice that of white women, and minority adolescents are almost five times as likely to die of ectopic pregnancy. In this article, causative factors are identified, and the potential for race, gender, and age bias in diagnosis and treatment is discussed. Involvement by nurses in preventive programs, clinical research, and advocacy for policy change may help reduce ectopic pregnancy mortality rates.

Surveillance for ectopic pregnancy--United States, 1970-1989.

PROBLEM/CONDITION: From 1970 through 1989, hospitalizations for ectopic pregnancy have increased in the United States; the number of cases has increased fivefold, from 17,800 to 88,400. REPORTING PERIOD COVERED: 1970-1989. DESCRIPTION OF SYSTEM: Reported ectopic pregnancies were estimated from data collected by CDC's National Center for Health Statistics (NCHS) as part of the ongoing National Hospital Discharge Survey. Data from responding hospitals were weighted to represent national estimates. The number of deaths resulting from ectopic pregnancy was based on U.S. vital statistics collected by NCHS. Denominators for calculating ectopic pregnancy rates were the total number of reported pregnancies, which includes live births, legal induced abortions, and ectopic pregnancies. Data for live births were obtained from NCHS natality statistics and data for legal induced abortions from CDC's Division of Reproductive Health. RESULTS: From 1970 through 1989, more than one million ectopic pregnancies were estimated to have occurred among women in the United States; the rate increased by almost fourfold, from 4.5 to 16.0 ectopic pregnancies per 1,000 reported pregnancies. Although ectopic pregnancies accounted for < 2% of all reported pregnancies during this period, complications of this condition were associated with approximately 13% of all pregnancy-related deaths. During this period, the risk of death associated with ectopic pregnancy decreased by 90%: the case-fatality rate declined from 35.5 deaths per 10,000 ectopic pregnancies in 1970 to 3.8 in 1989. The risks of ectopic pregnancy and death from its complications were consistently higher for blacks and other racial/ethnic minorities than for whites throughout the period. INTERPRETATION: Although the general trend has been for the numbers and rates of ectopic pregnancy to increase over the 20-year period, the variability of the data does not permit meaningful conclusions to be made about year-to-year changes in the estimates of ectopic pregnancies, especially for the years 1988 and 1989. ACTIONS TAKEN: These findings indicate the need to characterize behaviors and risk factors that may respond to preventive interventions. Until these risks factors are better characterized, early detection and appropriate management of ectopic pregnancies will remain the most effective means of reducing the morbidity and mortality associated with this condition.

Ectopic pregnancy--United States, 1988-1989.

Although the number and rate of ectopic pregnancies in the United States increased from 1970 through 1987, they stabilized from 1987 through 1989 (1). This report presents data regarding the number and rate of ectopic pregnancies and ectopic pregnancy-related deaths in the United States from 1988 through 1989 and compares those data with information reported since 1970.
