Developing a Workforce for Health in North Carolina: Planning for the Future.

Among the many trends influencing health and health care delivery over the next decade, three are particularly important: the transition to value-based care and increased focus on population health; the shift of care from acute to community-based settings; and addressing the vulnerability of rural health care systems in North Carolina.

Accelerating Climate Action Through Academic Health Systems: Leadership's Call to Duty.

This Viewpoint makes the case for academic health systems to lead the way on climate change action in the US, including planning to reduce greenhouse gas emissions, educating current and future clinicians, and communicating with their patients and communities.

Racial/ethnic disparities in obstetric outcomes and care: prevalence and determinants.

Wide disparities in obstetric outcomes exist between women of different race/ethnicities. The prevalence of preterm birth, fetal growth restriction, fetal demise, maternal mortality, and inadequate receipt of prenatal care all vary by maternal race/ethnicity. These disparities have their roots in maternal health behaviors, genetics, the physical and social environments, and access to and quality of health care. Elimination of the health inequities because of sociocultural differences or access to or quality of health care will require a multidisciplinary approach. We aim to describe these obstetric disparities, with an eye toward potential etiologies, thereby improving our ability to target appropriate solutions.

Racial and ethnic disparities in benign gynecologic conditions and associated surgeries.

Common gynecologic conditions and surgeries may vary significantly by race or ethnicity. Uterine fibroid tumors are more prevalent in black women, and black women may have larger, more numerous fibroid tumors that cause worse symptoms and greater myomectomy complications. Some, but not all, studies have found a higher prevalence of endometriosis among Asian women. Race and ethnicity are also associated with hysterectomy rate, route, and complications. Overall, the current literature has significant deficits in the identification of racial and ethnic disparities in the incidence of fibroid tumors, endometriosis, and hysterectomy. Further research is needed to better define racial and ethnic differences in these conditions and to examine the complex mechanisms that may result in associated health disparities.

Maternal and paternal race/ethnicity are both associated with gestational diabetes.

OBJECTIVE: The objective of the study was to examine the rates of gestational diabetes mellitus (GDM) associated with both maternal and paternal race/ethnicity. STUDY DESIGN: This was a retrospective cohort study of all women delivered within a managed care network. Rates of GDM were calculated for maternal, paternal, and combined race/ethnicity. RESULTS: Among the 139,848 women with identified race/ethnicity, Asians had the highest rate (P < .001) of GDM (6.8%) as compared with whites (3.4%), African Americans (3.2%), and Hispanics (4.9%). When examining race/ethnicity controlling for potential confounders, we found that the rates of GDM were higher among Asian (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.4-1.6) and Hispanic (aOR, 1.2; 95% CI, 1.1-1.4) women as well as Asian (aOR, 1.4; 95% CI, 1.3-1.5) and Hispanic (aOR, 1.3; 95% CI, 1.2-1.4) men as compared with their white counterparts. CONCLUSION: We found that rates of GDM are affected by both maternal and paternal race/ethnicity. In both Asians and Hispanics, maternal and paternal race are equally associated with an increase in GDM. These differences may inform further investigation of the pathophysiology of GDM.

Computerized prenatal genetic testing decision-assisting tool: a randomized controlled trial.

OBJECTIVE: Guidelines for fetal aneuploidy testing recommend that screening and diagnostic testing be made available to pregnant women of all ages and that providers explain the differences between these tests to help their patients make informed testing decisions. We sought to estimate the effect of a computerized, interactive prenatal testing decision tool on prenatal testing decision making. METHODS: Four hundred ninety-six English- or Spanish-speaking women at 20 or fewer weeks of gestation were randomly assigned to view the interactive prenatal testing decision tool or the California Department of Health Services' educational booklet. Primary outcomes were knowledge, risk awareness, intervention satisfaction, decisional conflict, and among women aged at least 35 years, use of invasive diagnostic testing. RESULTS: Women assigned to the interactive prenatal testing decision tool had higher knowledge scores (79.5% compared with 64.9%, P<.001), were more likely to correctly estimate their risk of procedure-related miscarriage (64.9% compared with 48.1%, P=.002) and carrying a Down syndrome-affected fetus (63.5% compared with 15.1%, P<.001), were more satisfied with the intervention (P<.001), and had less decision uncertainty (P<.001) than controls after viewing the intervention. Most of these differences persisted over time. Among women aged at least 35 years, the interactive prenatal testing decision tool viewers who were originally less inclined to undergo invasive testing were ultimately more likely than similarly inclined controls to have amniocentesis or chorionic villus sampling (44.8% compared with 29.2%), whereas those who were originally more inclined to undergo an invasive procedure ultimately were less likely than similarly inclined controls to have a diagnostic procedure (84.6% compared with 94.9%; P=.015 for interaction). CONCLUSION: Using an interactive prenatal testing decision tool results in more informed prenatal genetic testing decisions than viewing standard educational booklets.

Who is at risk for prolonged and postterm pregnancy?

OBJECTIVE: The objective of the study was to examine risk factors for postterm (gestational age >or= 42 weeks) or prolonged (gestational age >or= 41 weeks) pregnancy. STUDY DESIGN: We conducted a retrospective cohort study of all term, singleton pregnancies delivered at a mature, managed care organization. The primary outcome measures were the rates of pregnancies greater than 41 or 42 weeks' gestation. Multivariable logistic regression models were used to control for potential confounding and interaction. RESULTS: Specific risk factors for pregnancy beyond 41 weeks of gestation include obesity (adjusted odds ratio [aOR], 1.26; 95% confidence interval [CI], 1.16-1.37), nulliparity (aOR, 1.46; 95% CI 1.42-1.51), and maternal age 30-39 years (aOR, 1.06; 95% CI, 1.02-1.10) and 40 years or older (aOR, 1.07; 95% CI, 1.02-1.12). Additionally, African American, Latina, and Asian race/ethnicity were all associated with a lower risk of reaching 41 or 42 weeks of gestation. CONCLUSION: Our findings suggest that there may be biological differences that underlie the risk for women to progress to 41 or 42 weeks of gestation. In particular, obesity is a modifiable risk factor and could potentially be prevented with prepregnancy or interpregnancy interventions.

Ending cervical cancer screening: attitudes and beliefs from ethnically diverse older women.

OBJECTIVE: Guidelines support ending cervical cancer screening in women aged 65-70 years and older with previous normal testing, but little is known about older women's attitudes and beliefs about ending screening. STUDY DESIGN: We conducted face-to-face interviews with 199 women aged 65 and older in English, Spanish, Cantonese, or Mandarin. RESULTS: Most interviewees were nonwhite (44.7% Asian, 18.1% Latina, and 11.6% African American). Most (68%) thought lifelong screening was either important or very important, a belief held more strongly by African American (77%) and Latina (83%) women compared with women in other ethnic groups (P < .01). Most (77%) had no plans to discontinue screening or had ever thought of discontinuing (69%). When asked if they would end screening if recommended by their physician, 68% responded "yes." CONCLUSION: The majority of these women believe that lifelong cervical cancer screening is important. Many women, however, reported that they would end screening if recommended by their physician.

Perceived risk of prenatal diagnostic procedure-related miscarriage and Down syndrome among pregnant women.

OBJECTIVE: The objective of the study was to identify correlates of perceived risk of carrying a Down syndrome-affected fetus or experiencing a procedure-related miscarriage among a diverse group of pregnant women. STUDY DESIGN: We conducted a cross-sectional survey of 1081 English-, Spanish-, or Chinese-speaking women receiving prenatal care in the San Francisco Bay area. Perceived risk of procedure-related miscarriage or carrying a Down syndrome-affected fetus was assessed using a linear rating scale from 0 (no risk) to 1 (high risk). Bivariate and multivariable analyses were used to explore associations between maternal characteristics including age, race/ethnicity, and socioeconomic status and perceived risks of carrying a Down syndrome-affected fetus or experiencing a procedure-related miscarriage. RESULTS: Women aged 35 years old or older had a higher perceived risk of Down syndrome than younger women (0.28 vs 0.22 on a scale from 0 to 1, P < .001) but a lower perceived risk of a procedure-related miscarriage (0.31 vs 0.36, P = .004). In multivariable linear regression analysis among women younger than age 35 years, the perceived risk of carrying a Down syndrome-affected fetus was higher in women who had not attended college (+0.06, P = .019) or had poor self-perceived health status (+0.08, P = .045). Latinas (+0.11, P = .008), women with an annual income less than $35,000 (+0.09, P = .003), and those who had difficulty conceiving (+0.09, P = .026) had higher perceived procedure-related miscarriage risk. Among women aged 35 years or older, perceived risk of carrying a Down syndrome-affected fetus was associated with the inclination to undergo prenatal diagnosis. CONCLUSION: Women's perceived risks of carrying a Down syndrome-affected fetus or having a procedure-related miscarriage are associated with numerous characteristics that have not been shown to be associated with the actual risks of these events. These perceived risks are associated with prenatal diagnostic test inclination. Understanding patients' risk perceptions and effectively communicating risk is critical to helping patients make informed decisions regarding use of invasive prenatal testing.

First- vs second-trimester ultrasound: the effect on pregnancy dating and perinatal outcomes.

OBJECTIVE: The objective of the study was to examine the effect of first-trimester obstetric ultrasound (OBUS) on the measurement of the effect of complications ascribed to postterm pregnancies. STUDY DESIGN: We conducted a retrospective cohort study of all term, singleton pregnancies delivered at our institution who had an OBUS at a gestation of 24 weeks or less. Those women who underwent an OBUS at a gestation of 12 weeks or less (OBUS12) were compared with those who had an OBUS at 13-24 weeks of gestation (OBUS13-24). The primary outcome measures were the rates of postterm pregnancies greater than 41 or 42 weeks' gestation. Secondary outcomes were the differences between the postterm and term gestations in maternal and neonatal outcomes. RESULTS: In the OBUS12 group, the rate of postterm pregnancy 42 weeks or longer was lower (2.7%) as compared with the OBUS13-24 group (3.7%, P = .022). With regard to reaching 41 weeks of gestation, the OBUS12 group was again lower (18.2%) as compared with the OBUS13-24 group (22.1%, P < .001). There were also fewer postterm inductions at 42 weeks or longer in the OBUS12 group (1.8%) as compared with the OBUS13-24 group (2.6%, P = .017). When comparing perinatal outcomes between those women who reached 41 weeks of gestation and those prior to 41 weeks of gestation, the OBUS12 group demonstrated greater differences between these 2 groups. CONCLUSION: Our findings suggest that earlier obstetric ultrasound, which leads to better pregnancy dating, reduces the rate of estimated postterm pregnancies. This may, in turn, reduce unnecessary intervention and lead to better identification of postterm pregnancies at greater risk of complications.

Perinatal outcomes in low-risk term pregnancies: do they differ by week of gestation?

OBJECTIVE: The objective of the study was to examine whether the risk of perinatal complications increases with increasing gestational age among term pregnancies. STUDY DESIGN: This is a retrospective cohort study of low-risk women with term, singleton births in 2003 in the United States. Gestational age was subgrouped into 37, 38, 39, 40, and 41 completed weeks. Statistical comparison was performed using chi(2) test and multivariable logistic regression models, with 39 weeks' gestation as the referent. RESULTS: There were 2,527,766 women meeting study criteria. Compared with 39 weeks, delivery at 37 or 38 weeks had lower risk of febrile morbidity but slightly higher risk of cesarean delivery. Delivery at 40 or 41 weeks was also associated with higher overall maternal morbidity. For neonates, delivery at 40 or 41 weeks had higher risk of birthweight greater than 4500 g, neonatal injury (40 weeks: adjusted odds ratio [aOR] 1.11 [95% confidence interval (CI), 1.05-1.18]; 41 weeks: aOR 1.27 [95% CI, 1.17-1.37]) and meconium aspiration (40 weeks: aOR 1.55 [95% CI, 1.43-1.69]; 41 weeks: aOR 2.12 [95% CI, 1.91-2.35]). Delivery at 37 or 38 weeks had higher risk of hyaline membrane disease (37 weeks: aOR 3.12 [95% CI, 2.90-3.38]); 38 weeks: aOR 1.30 [95% CI, 1.19-1.43]) but lower risk of meconium aspiration. CONCLUSION: The risk of cesarean delivery and neonatal morbidity in low-risk women increases at 40 weeks and beyond, whereas the odds of serious neonatal pulmonary disease were highest at 37 weeks. Recognition of such variation in term outcomes should lead providers to avoid iatrogenic morbidity and consider interventions to prevent complications of late-term pregnancy.

Time of delivery and neonatal morbidity and mortality.

OBJECTIVE: The objective of the study was to examine the association between time of delivery and neonatal outcomes in term deliveries. STUDY DESIGN: We conducted a retrospective cohort study of all term pregnancies delivered at an academic institution with 24-hour in-house obstetric and anesthesia coverage. Time of delivery was categorized as day (7 am to 6 pm), evening (6 pm to 12 midnight), and late night (12 midnight to 7 am). Outcomes included 5-minute Apgar less than 7, umbilical artery pH less than 7.0, base excess less than -12, admission to the neonatal intensive care unit (NICU), and neonatal death. We excluded patients delivered via cesarean delivery not in labor. We had greater than 80% power to detect a 25% difference in Apgar score, base excess, and admission to the NICU and 80% power to detect a 50% difference in umbilical artery pH less than 7.0. RESULTS: Among the 34,424 deliveries meeting inclusion criteria, 15,664 were during the day, 8495 were during the evening, and 10,265 were during the night. In univariate comparisons, there were no statistically significant differences in neonatal outcomes. For example, the rate of pH less than 7.0 was 0.7% during the day, 1.0% in the evening, and 0.6% at night (P = .12). Admissions to the NICU were 3.6% during the day, 3.7% in the evening, and 3.5% at night (P = .81). When we controlled for obstetric history, demographic factors, and labor characteristics, there were still no differences in rates of either neonatal morbidity or mortality by time of delivery. CONCLUSION: At our institution, we could not demonstrate any significant differences in neonatal morbidity or mortality by time of day among neonates delivered at term. These data can be used to counsel patients and families concerned about differences in time of delivery and potential impact on their infant's health. Future research should include time of delivery in relation to maternal and neonatal outcomes in various types of inpatient settings.

Risk of cervical cancer associated with extending the interval between cervical-cancer screenings.

BACKGROUND: Although contemporary guidelines suggest that the intervals between Papanicolaou tests can be extended to three years among low-risk women with previous negative tests, the excess risk of cervical cancer associated with less frequent than annual screening is uncertain. METHODS: We determined the prevalence of biopsy-proven cervical neoplasia among 938,576 women younger than 65 years of age, stratified according to the number of previous consecutive negative Papanicolaou tests. Using a Markov model that estimates the rate at which dysplasia will progress to cancer, we estimated the risk of cancer within three years after one or more negative Papanicolaou tests, as well as the number of additional Papanicolaou tests and colposcopic examinations that would be required to avert one case of cancer given a particular interval between screenings. RESULTS: Among 31,728 women 30 to 64 years of age who had had three or more consecutive negative tests, the prevalence of biopsy-proven cervical intraepithelial neoplasia of grade 2 was 0.028 percent and the prevalence of grade 3 neoplasia was 0.019 percent; none of the women had invasive cervical cancer. According to our model, the estimated risk of cancer with annual Papanicolaou tests for three years was 2 in 100,000 among women 30 to 44 years of age, 1 in 100,000 among women 45 to 59 years of age, and 1 in 100,000 among women 60 to 64 years of age; these risks would be 5 in 100,000, 2 in 100,000, and 1 in 100,000, respectively, if screening were performed once three years after the last negative test. To avert one additional case of cancer by screening 100,000 women annually for three years rather than once three years after the last negative test, an average of 69,665 additional Papanicolaou tests and 3861 colposcopic examinations would be needed in women 30 to 44 years of age and an average of 209,324 additional Papanicolaou tests and 11,502 colposcopic examinations in women 45 to 59 years of age. CONCLUSIONS: As compared with annual screening for three years, screening performed once three years after the last negative test in women 30 to 64 years of age who have had three or more consecutive negative Papanicolaou tests is associated with an average excess risk of cervical cancer of approximately 3 in 100,000.

Effect of noncancerous pelvic problems on health-related quality of life and sexual functioning.

OBJECTIVE: To assess the effect of abnormal uterine bleeding and pelvic pain and pressure on health-related quality of life and sexual functioning and assess treatment satisfaction. METHODS: This is a cross-sectional study of 1,493 sociodemographically diverse women who were seeking care for noncancerous pelvic problems and who had not undergone hysterectomy. Participants were asked about symptoms, attitudes, health-related quality of life, sexual functioning, and treatment satisfaction. Preference for current health was measured using the time tradeoff metric, which asked respondents to estimate the number of years of life they would be willing to trade off to not have a uterine condition. Multivariable logistic regression was used to identify determinants of treatment satisfaction. RESULTS: Most (82.7%) participants reported a complete lack of or only partial symptom resolution, and 42.3% reported that their pelvic problems interfered with their ability to have and enjoy sex. Mean Short Form-12 Physical (43-49) and Mental (41-44) Component Summary scores were substantially lower than population norms for women aged 40-49 years. Mean current health time tradeoff scores ranged from 0.78 to 0.88. Satisfaction with Western medicines ranged from 31.3% (progestin intrauterine device) to 58.2% (opiates) and with uterine-preserving surgery from 20.0% (dilation and curettage) to 51.0% (myomectomy); 27.7 % of the women who used acupuncture were satisfied. Participants with lower educational attainment, greater symptom resolution, and less interference of pelvic problems with sex were more likely to be satisfied. CONCLUSION: Noncancerous pelvic problems are associated with serious decrements in health-related quality of life and sexual functioning and low rates of treatment satisfaction. LEVEL OF EVIDENCE: II.

Prepregnancy body mass index and the length of gestation at term.

OBJECTIVE: The purpose of this study was to examine the relationship between prepregnancy body mass index (BMI) and length of gestation at term. STUDY DESIGN: This was a retrospective study of 9336 births at the University of California, San Francisco, at > or = 37 weeks' gestation. We performed univariate and multivariable analyses of the associations between prepregnancy BMI and length of gestation (> or = 40, > or = 41, and > or = 42 weeks' gestation). RESULTS: Overweight women were more likely to deliver at > or = 40, > or = 41, and > or = 42 weeks' gestation than were women who were underweight or normal weight. In multivariable analyses, higher prepregnancy BMI was associated with higher risk of progressing past 40 weeks. Obese women had 69% higher adjusted odds of reaching 42 weeks' gestation, compared with women of normal prepregnancy BMI (adjusted odds ratio, 1.69; 95% confidence interval, 1.23-2.31). CONCLUSION: Higher BMI is associated with prolonged gestation at term. Achieving optimal BMI before conception may reduce the risk of postterm pregnancy and its associated complications.

Maternal and obstetric complications of pregnancy are associated with increasing gestational age at term.

OBJECTIVE: We sought to estimate when rates of maternal pregnancy complications increase beyond 37 weeks of gestation. STUDY DESIGN: We designed a retrospective cohort study of all low-risk women delivered beyond 37 weeks' gestational age from 1995 to 1999 within a mature managed care organization. Rates of mode of delivery and maternal complications of labor and delivery were examined by gestational age with both bivariate and multivariable analyses. RESULTS: We found that, among the 119,254 women who delivered at 37 completed weeks and beyond, the rates of operative vaginal delivery (OR 1.15, 95% CI 1.09, 1.22), 3rd- or 4th-degree perineal laceration (OR 1.15, 95% CI 1.06, 1.24), and chorioamnionitis (OR 1.32, 95% CI 1.21, 1.44) all increased at 40 weeks as compared to 39 weeks of gestation (P < .001), and rates of postpartum hemorrhage (OR 1.21, 95% CI (1.10, 1.32), endomyometritis (OR 1.46, 95% CI 1.14, 1.87), and primary cesarean delivery (1.28, 95% CI 1.20, 1.36) increased at 41 weeks of gestation (P < .001). The cesarean indications of nonreassuring fetal heart rate (OR 1.81, 95% CI 1.49, 2.19) and cephalo-pelvic disproportion (OR 1.64, 95% CI 1.40, 1.94) increased at 40 weeks of gestation (P < .001). CONCLUSION: We found that the risk of maternal peripartum complications increase as pregnancy progresses beyond 40 weeks of gestation. Management of pregnancies that progress past their EDC should include counseling regarding the risks of increasing gestational age.
