Relocation of Maternal-Fetal Medicine Specialists in the United States.

OBJECTIVE: To examine patterns in relocation of maternal-fetal medicine (MFM) specialists during the recent 10 years. STUDY DESIGN: This descriptive study analyzed the migration of MFM specialists between 2006 and 2016 based on county locations. Year-to-year comparisons of physicians in active clinical practice were performed. Demographic and county characteristics were gathered from three data resources. A multivariable logistic regression model was used to identify factors associated with relocation. RESULTS: An average of 7.4% (5.5-10.8%) of all 1,104 (1,103-1,115) MFM specialists moved per year. Approximately one in three (36%) relocated during the 10 years, usually once or twice. The likelihood of relocation was higher if the physician was younger, especially under 40 years compared with those aged 60 years and older (odds ratio [OR] = 2.08; 95% confidence interval [CI]: 1.36-3.19). No differences were noted based on gender and race/ethnicity. Physicians in independent group practices were more inclined to relocate, especially when compared with those in a solo or two-physician practice (OR = 0.38; 95% CI: 0.27-0.54). Relocations were primarily between urban counties (95.9%) and showed a significant regional pattern. CONCLUSION: Approximately one in three MFM specialists relocated in the past 10 years, mostly between urban counties and especially in independent group practices.

Female Physicians in Maternal-Fetal Medicine: A 32-Year Perspective.

OBJECTIVE: To examine trends of female physicians either pursuing fellowships or in active practice in maternal-fetal medicine (MFM). METHODS: This observational study examined complete sets of MFM fellows and active members of the Society for Maternal-Fetal Medicine (SMFM) between 1985 and 2016. Databases from SMFM, American College of Obstetricians and Gynecologists (ACOG), and Accreditation Council for Graduate Medical Education were used. Analysis of covariance testing was used to assess interactions over time between groups. RESULTS: The proportion of female MFM fellows increased steadily from 17.1% in 1985 to 72.5% in 2016. The proportion of females grew more rapidly among the MFM fellows than obstetrics and gynecology (ob-gyn) residents (2.1 vs. 1.4% per year; p = 0.001) and among those who were active SMFM members than ACOG Fellows (1.4 vs. 1.2% per year; p = 0.013). Slightly more than half (52.4%) of all SMFM members are now female and will approach two-thirds (64.4%) by 2025 (compared with 53.4% in 2016 and 65.3% in 2025 of ACOG fellows). CONCLUSION: The rising proportion of female MFM fellows is directly related to the high number of female ob-gyn residents. Females comprise slightly more than half of all active SMFM members now and projected to approach two-thirds by 2025.

Retirement Age Ranges from Clinical Practice of Maternal-Fetal Medicine Physicians.

Objectives Retirement of "baby boomer" physicians is a matter of growing concern in light of the shortage of certain physician groups. The objectives of this investigation were to define what constitutes a customary retirement age range of maternal-fetal medicine (MFM) physicians and examine how that compares with other obstetrician-gynecologist (ob-gyn) specialists. Study Design This descriptive study was based on American Medical Association Masterfile survey data from 2010 to 2014. Data from the National Provider Identifier were used to correct for upward bias in reporting retirement ages. Only physicians engaged in direct patient care between ages 55 and 80 years were included. Primary outcomes involved comparisons of retirement ages of male and female physicians with other ob-gyn specialties. Results Interquartile ranges of retirement ages were similar between specialists in MFM (64.1-71.1), gynecologic oncology (62.1-68.9), reproductive endocrinology and infertility (64.1-71.7), and general ob-gyn (61.5-67.9). In every specialty, women retired earlier, while males in MFM were most likely to retire at the oldest age (median 70.0). Conclusion MFM physicians usually retired from clinical practice between ages 64 and 71 years, which is similar to other ob-gyn specialists. Females retired earlier, however, which may impact the overall supply as more females pursue MFM careers.

When Do Primary Care Physicians Retire? Implications for Workforce Projections.

PURPOSE: Retirement of primary care physicians is a matter of increasing concern in light of physician shortages. The joint purposes of this investigation were to identify the ages when the majority of primary care physicians retire and to compare this with the retirement ages of practitioners in other specialties. METHODS: This descriptive study was based on AMA Physician Masterfile data from the most recent 5 years (2010-2014). We also compared 2008 Masterfile data with data from the National Plan and Provider Enumeration System to calculate an adjustment for upward bias in retirement ages when using the Masterfile alone. The main analysis defined retirement as leaving clinical practice. The primary outcome was construction of a retirement curve. Secondary outcomes involved comparisons of retirement interquartile ranges (IQRs) by sex and practice location across specialties. RESULTS: The 2014 Masterfile included 77,987 clinically active primary care physicians between ages 55 and 80 years. The median age of retirement from clinical activity of all primary care physicians who retired in the period from 2010 to 2014 was 64.9 years, (IQR, 61.4-68.3); the median age of retirement from any activity was 66.1 years (IQR, 62.6-69.5). However measured, retirement ages were generally similar across primary care specialties. Females had a median retirement about 1 year earlier than males. There were no substantive differences in retirement ages between rural and urban primary care physicians. CONCLUSIONS: Primary care physicians in our data tended to retire in their mid-60s. Relatively small differences across sex, practice location, and time suggest that changes in the composition of the primary care workforce will not have a remarkable impact on overall retirement rates in the near future.

Validity of Self-Reported Drug Use Information Among Pregnant Women.

INTRODUCTION: This study assesses validity of self-report for the use of major classes of illicit drugs and opioid-maintenance therapy among pregnant women at a substance abuse treatment program. METHODS: Analyses used data collected from 83 pregnant women in a prospective cohort study at the University of New Mexico. Study participants with a history of substance abuse were screened and, if eligible, enrolled during an early prenatal care visit. A follow-up interview was conducted shortly after delivery. Self-reported information about drug use later in pregnancy was compared with urine drug screen (UDS) results collected during the third trimester. Simple kappa (k) and prevalence-and-bias-adjusted kappa (PABAK) coefficients were calculated as the measures of agreement. Sensitivity and specificity of self-report for each drug class were estimated using UDS as the 'gold standard'. RESULTS: The sample included a large proportion of ethnic minority (80% Hispanic/Latina and 7% American Indian) and socially disadvantaged (50% less than high school education and 94% Medicaid-insured) pregnant women. On average, patients had 4.8 ± 3.0 urine drug screens during the third trimester. Sensitivity of self-report was low (<60%) for all classes of illicit drugs; however, marijuana and opioids demonstrated slightly higher sensitivity (57.9 and 58.3%, respectively) than other classes (<47%). CONCLUSIONS: This study found substantial underreporting for all classes of illicit drugs among pregnant women in a substance abuse treatment program. Rates of underreporting are expected to be higher among the general population of pregnant women.

Diversity of Physician Faculty in Obstetrics and Gynecology.

OBJECTIVE: To investigate physician faculty diversity in obstetrics and gynecology (ob-gyn) and how it compares with other clinical departments and medical student demographics. STUDY DESIGN: Data from the Association of American Medical College's Faculty Roster were extracted to differentiate full-time physician faculty by gender and by underrepresentation in medicine (Black, Hispanic, Native American/ Alaskans, and Pacific Islanders). Whole population data were updated on a rolling basis from the earliest year of reliable data (1973) to the most recent year (2012). RESULTS: The total number of full-time ob-gyn faculty increased from 922 in 1973 to 4,208 in 2012. The increase in proportion of faculty who were women (from 9.9% to 52.7%) contributed to the growth of underrepresented faculty (from 7.7% to 13.3%) during this period. Percentages of ob-gyn faculty who were women and underrepresented in 2012 were higher than in other core clinical departments and similar to those of current medical student matriculants. CONCLUSION: Expansion of physician faculty in ob-gyn over the past 40 years has led to greater diversity than exists in many other departments and is more reflective of medical student demographics.

Fetal Growth Outcomes in a Cohort of Polydrug- and Opioid-Dependent Patients.

OBJECTIVES: To evaluate the effects of prenatal polydrug and exclusive opioid use on fetal growth outcomes. METHODS: This analysis relied on the data obtained from two prospective cohorts at the University of New Mexico. For both cohorts, pregnant women were recruited during one of their prenatal care visits and followed up to delivery. The merged sample included 59 polydrug users, 22 exclusive opioid users, and 278 abstinent controls. Continuous growth measures (birth weight, height, occipital frontal circumference [OFC], and corresponding sex-specific percentiles) were compared by ANOVA and ANCOVA in bivariate and multivariable analyses, respectively. Categorical outcomes (prevalence of small-for-gestational age [SGA] for weight, length, and OFC) were compared among groups by Chi-square and multivariable logistic regression analyses.. RESULTS: The sample included a large proportion of ethnic minorities (78.8% Hispanic) and patients with low educational attainment (68% ≤ high school). The risk of microcephaly (OFC<10th percentile) was significantly greater in the polydrug (OR=4.7; 95% CI: 2.0; 10.8) and exclusive opioid (OR=2.8; 95% CI: 1.0; 8.1) groups compared to abstinent controls. CONCLUSION: Given that microcephaly is often associated with serious neurocognitive and behavioral deficits later in life, our finding of 49.2% incidence of microcephaly among polydrug users is alarming and requires further investigation.

Considerations about retirement from clinical practice by obstetrician-gynecologists.

Retirement of obstetrician-gynecologists is becoming a matter of increasing concern in light of an expected shortage of practicing physicians. Determining a retirement age is often complex. We address what constitutes a usual retirement age range from general clinical practice for an obstetrician-gynecologist, compare this with practitioners in other specialties, and suggest factors of importance to obstetrician-gynecologists before retirement. Although the proportion of obstetrician-gynecologists ≥55 years old is similar to other specialists, obstetrician-gynecologists retire at younger ages than male or female physicians in other specialties. A customary age range of retirement from obstetrician-gynecologist practice would be 59-69 years (median, 64 years). Women, who constitute a growing proportion of obstetrician-gynecologists in practice, retire earlier than men. The large cohort of "baby boomer" physicians who are approaching retirement (approximately 15,000 obstetrician-gynecologists) deserves tracking while an investigation of integrated women's health care delivery models is conducted. Relevant considerations would include strategies to extend the work longevity of those who are considering early retirement or desiring part-time employment. Likewise volunteer work in underserved community clinics or teaching medical students and residents offers continuing personal satisfaction for many retirees and preservation of self-esteem and medical knowledge.

Advances in ultrasound imaging for congenital malformations during early gestation.

BACKGROUND: With refinement in ultrasound technology, detection of fetal structural abnormalities has improved and there have been detailed reports of the natural history and expected outcomes for many anomalies. The ability to either reassure a high-risk woman with normal intrauterine images or offer comprehensive counseling and offer options in cases of strongly suspected lethal or major malformations has shifted prenatal diagnoses to the earliest possible gestational age. METHODS: When indicated, scans in early gestation are valuable in accurate gestational dating. Stricter sonographic criteria for early nonviability guard against unnecessary intervention. Most birth defects are without known risk factors, and detection of certain malformations is possible in the late first trimester. RESULTS: The best time for a standard complete fetal and placental scan is 18 to 20 weeks. In addition, certain soft anatomic markers provide clues to chromosomal aneuploidy risk. Maternal obesity and multifetal pregnancies are now more common and further limit early gestation visibility. CONCLUSION: Other advanced imaging techniques during early gestation in select cases of suspected malformations include fetal echocardiography and magnetic resonance imaging.

Clinical faculty: taking the lead in teaching quality improvement and patient safety.

Despite efforts by health professional organizations to promote efforts in quality improvement, patient safety, and cost reduction, the issue remains that US medical schools and teaching hospitals do not have an adequate supply of skilled faculties to lead these efforts. Recognizing this need, an expert, multidisciplinary panel was convened by the American Association of Medical Colleges in 2012 to develop a systematic strategy to build a critical mass of academic health center faculties to lead and implement education in those three areas. In the last year, the American Association of Medical Colleges has launched a national institution-based initiative to train faculty in all clinical specialties, which includes those in obstetrics-gynecology. This comprehensive program consists of interactive experiential learning workshops, web-based resources, a national community of learners, implementation of educational initiatives, and dissemination of outcomes. Those faculties will be invaluable in leading and disseminating educational programs that embed quality improvement and patient safety across the continuum of women's healthcare to all faculty members and residents.

The validity of phosphatidylethanol in dried blood spots of newborns for the identification of prenatal alcohol exposure.

BACKGROUND: Accurate identification of prenatal alcohol exposure (PAE) in the newborn period offers an opportunity for early identification of children at risk of future neurocognitive problems and the implementation of interventional approaches earlier in life. PAE newborn screening by measuring phosphatidylethanol in dried blood spot (PEth-DBS) cards is feasible, logistically easier, and more cost-efficient compared with other biomarkers. However, the sensitivity and specificity of this method have yet to be established. METHODS: This prospective cohort study examined validity of PEth-DBS among 28 infants with PAE and 32 controls relative to maternal self-report and other biomarkers. Pregnant women were recruited from a University of New Mexico clinic and followed to early postpartum period. The composite index, which was based on self-reported measures of alcohol use and allowed to classify subjects into PAE and control groups, was the criterion measure used to estimate sensitivity and specificity of PEth-DBS. RESULTS: The study included large proportions of patients representing ethnic minorities (7.4% American Indian, 81.7% Hispanic/Latina), low education (54.2%

Trends in family physicians performing deliveries, 2003-2010.

OBJECTIVE: This observational study examined the proportion of family physicians continuing to perform deliveries from 2003-2010. METHODS: Data were collected annually from the same census questionnaire completed by family physicians who passed their recertification examination. Aggregated responses began in 2003 when data first became available electronically and ended in 2009 before recertification changes. Using cross-sectional design and logistic regression analysis, we examined associations between physician demographic or geographic factors and performance of deliveries. RESULTS: The sample consisted of 49,267 family physicians between 2003 and 2009, including 7,456 in 2009. The proportion performing any deliveries declined by 40.6 percent, from 17.0 percent in 2003 to 10.1 percent in 2009. Most recently, 5.5 percent of all family physicians delivered 1-25 babies per year, whereas 2.8 percent delivered 26-50, and 1.9 percent delivered ≥ 51. Those who performed deliveries were most likely to be junior members of a partnership or group practice, and provided prenatal and newborn care. Deliveries were more common in nonmetropolitan areas, where other obstetric practitioners were unavailable. CONCLUSIONS: The proportion of family physicians performing deliveries continues to decline with most delivering 25 or fewer babies per year. This change will require more effort by obstetrician-gynecologists and midwives in being primary birth attendants.

Long-term trends in applicants for maternal-fetal medicine fellowship positions.

OBJECTIVE: To examine long-term trends in applicants for Maternal-Fetal Medicine (MFM) fellowship positions specifically following the prolongation of fellowship training in 1997 from 2 to 3 years. STUDY DESIGN: We conducted a review of the data from the National Residency Matching Program (NRMP) from 1992 to 2013 in order to compare the numbers of total applicants with those who matched. RESULTS: There was a significant decline in the number of applicants per year between 1997 and 2001. In the subsequent 12 years, the number of applicants exceeded the number of positions with nearly all programs being filled per year. After reaching a nadir of 60 fellowship positions in 2000, the numbers of programs and positions increased gradually to levels now equal to before prolongation of training. CONCLUSIONS: These findings should be helpful as pursuit of fellowship training is being considered earlier in residency and as the balance between generalists and subspecialists in obstetrics and gynecology is being more closely evaluated.

Geographical information systems for mapping maternal ground transport to level III care neonatal centers.

OBJECTIVE: The objective of this investigation was to determine maternal ground transport times from community hospitals to the nearest hospital offering comprehensive (level III) neonatal care within the contiguous United States. STUDY DESIGN: This observational study combined data from the 2010 U.S. Census tract and 2010 American Hospital Association Annual Survey. Level III (full complement of care) neonatal centers were plotted using 2010 geographical information systems (GIS) mapping software (ESRI, Redland, California, United States). Locations of level I (uncomplicated care) and level II (limited complicated care) centers and residences of reproductive-aged women (18 to 39 years old) were mapped to identify maternal ground transport times to level III centers. RESULTS: Most of the 584 level III neonatal centers were located in metropolitan areas (83.5%). The proportions of level I and level II hospitals within a 30-minute drive of a level III neonatal center were 19.8 and 47.3%, and 52.2 and 69.8% were within a 60-minute drive time. Ground transport times were shortest in the Northeast and metropolitan areas, and longest in the rural Great Plains and noncoastal West. CONCLUSION: GIS mapping enables health providers and health policy makers to better understand maternal ground transport times to current and future regional hospitals offering level III neonatal services.

Diversity in Academic Obstetrics and Gynecology.

Institutional transformation and moving diversity from the periphery to the core of excellence have increased the representation of both female and racial and ethnic minoritized populations in academic obstetrics and gynecology (OB/GYN). Enabling the recruitment and retention of diverse residents and faculty, measuring their contributions to the department academic and social missions, and providing a supportive environment will be important in the coming years as the changing OB/GYN workforce progresses through their careers.

Women Accessing Care at a National Network of Retail Health Clinics.

Background: Retail health clinics offer easy access and lower costs in seeking nonemergent and usually focused care. The objective of this observational study was to describe the use of retail clinic services by women at MinuteClinic at CVS, the largest network of retail clinics in the United States. Methods: The retail clinic's large database included complete national data for every in-person encounter as recorded on the same electronic health record. Virtual care and pharmacist-delivered services like COVID-19 testing were excluded from the analysis. The primary reason for the visit and the patient's age group (<15, 15-44, 45-64, ≥65 years) and self-reported sex were recorded at each encounter from the most recent 5 years (January 1, 2018, to December 31, 2022). Results: There were 17,969,483 encounters by women seeking care, and women ≥15 years old were more likely than men to attend the clinics. Half of all encounters (50.6%) were for non-gynecologic acute care, whereas one-third (33.6%) dealt with either an infection or the need for a vaccination. Gynecologic reasons involved 5.6% of all encounters in women ≥15 years of age. No obstetrical care was provided except for pregnancy testing with referral, acute non-obstetric needs, or guideline-recommended vaccinations. Conclusion: Women, especially of reproductive age, are more inclined than men to seek care at retail clinics. Acute care is the most common need, although requests for immunizations, infection screening and treatment, and reproductive health issues occurred often.

Sources of potential lead exposure among pregnant women in New Mexico.

The objectives of this study were to ascertain the prevalence and potential sources of lead exposure among pregnant women residing in a socially-disadvantaged immigrant community in Albuquerque, New Mexico. Pregnant women (n = 140) receiving prenatal care through a community clinic participated in a structured interview and screening to measure their blood lead levels (BLLs). Potential sources of lead exposure were ascertained by the CDC and New Mexico Department of Health questionnaires. Self-reported risk factors were examined as predictors of BLLs using multiple linear regression and partial least squares discriminant analysis. Most patients were Spanish-speaking (88.6%), Latina (95%), foreign-born (87.1%), lacked health insurance (86.4%), and had a high school education or lower (84.3%). While risk factors were prevalent in this population, only three women (2.1%) had BLLs ≥3 µg/dL. Results of multivariate analyses demonstrated that pica symptoms in pregnancy, history of elevated BLLs before pregnancy, use of non-commercial pottery, and living in older houses were important predictors of elevated BLLs. Although the prevalence of other risk factors relevant to immigrant communities (i.e., use of traditional/folk remedies and cosmetics, seasonings and food products from Mexico) was high, they were not predictive of elevated BLLs. Clinics providing prenatal care to immigrant Hispanic communities should carefully assess patients' pica symptoms, use of non-commercial pottery, and a history of elevated BLLs. Moreover, additional efforts need to focus on the development of screening questionnaires which better reflect exposures of concern in this population.
