The Intersection of Behavioral Economics and the General Medicine Literature.

Judgment and decision-making influence health-related behavior and clinical decision-making and, ultimately, health. It has been estimated that more than half of health disorders derive from behavioral consequences of unhealthy choices. We considered the question of how to better understand and improve decision-making in health and medicine through a narrative review of use and examples of concepts from Behavioral Economics, a field of study that combines insights from behavioral science and economic decision-making, in the 3 highest-impact general medicine journals.

Perinatal asphyxia from the obstetric standpoint.

Perinatal asphyxia remains one of the major causes of morbidity and mortality for term newborns. Though access to health care and birth attendants have decreased the rate, Neonatal encephalopathy (NE) has not been eliminated. Worldwide, women at socioeconomic disadvantage have the highest risk of delivering a neonate with NE. Neonates that will experience perinatal asphyxia cannot be easily identified prospectively and the intrapartum testing available is not specific enough to clearly indicate the best course of action in most cases. Despite this, training programs that aim to decrease morbidity and mortality from all causes appear to be associated with fewer cases of perinatal asphyxia. The current best approach is to support education and communication for all people involved in the care of birthing women. Ideally, new technology will address identification of the fetus likely to be affected or the fetus who is beginning to experience injury in advance of delivery.

External Cephalic Version in Cases of Imminent Delivery at Preterm Gestational Ages: A Prospective Series.

Objective When delivery of a breech fetus is required at a preterm gestational age, Cesarean delivery is often recommended. We performed a prospective patient series to assess the success rate and safety of performing external cephalic version (ECV) procedures on preterm fetuses as an alternative to Cesarean delivery. Study Design We performed a prospective clinical series of patients who required delivery with a malpresenting fetus at a preterm gestational age. Results ECV procedures were successful in singletons 50% of the time. No significant complications or cases of fetal mortality were documented. Conclusion ECV at preterm gestational ages may be an appropriate approach to management in patients requiring delivery. Larger series are needed to further document success rates and risks of the procedure.

Misoprostol in Addition to a Double-Balloon Catheter for Induction: A Double-Blind Randomized Controlled Trial.

OBJECTIVE: This article aims to evaluate whether the use of a double-balloon catheter with oral misoprostol results in a lower rate of cesarean and shorter times to delivery than the use of the double-balloon catheter with oral placebo. STUDY DESIGN: In a double-blind randomized controlled trial, a double-balloon catheter was used for induction of labor with two doses of either 50 µg of misoprostol or placebo. Outcomes included cesarean rate, time to vaginal delivery, change in Bishop's score, and oxytocin usage. RESULTS: A total of 343 women were screened and 199 randomized: 99 to the misoprostol arm and 100 to the placebo arm. Cesarean delivery rate was not different between the groups (misoprostol: 13.1% vs. placebo: 17.0%, p = 0.45). Time to vaginal delivery was significantly shorter (mean: 14.6 ± 6.9 vs. 20.8 ± 13.8 hours, p < 0.0001), change in Bishop's score was significantly greater (median: 5 vs. 4 points, p = 0.005), and use of oxytocin was significantly less frequent (86.9 vs. 98.0% patients, p = 0.01) in the misoprostol group. CONCLUSION: The use of a double-balloon catheter with oral misoprostol for induction did not reduce the cesarean delivery rate, but did result in shorter labors, a greater increase in Bishop's score, and a lower need for oxytocin use.

Does Maternal Body Mass Index Have an Effect on the Accuracy of Ultrasound-Derived Estimated Birth Weight?: A Retrospective Study.

OBJECTIVES: The purpose of this study was to investigate the relationship between the maternal body mass index (BMI) and the accuracy of ultrasound-derived birth weight. METHODS: A retrospective chart review was performed on women who had an ultrasound examination between 36 and 43 weeks' gestation and had complete delivery data available through electronic medical records. The ultrasound-derived fetal weight was adjusted by 30 g per day of gestation that elapsed between the ultrasound examination and delivery to arrive at the predicted birth weight. RESULTS: A total of 403 pregnant women met inclusion criteria. Age ranged from 13-44 years (mean ± SD, 28.38 ± 5.97 years). The mean BMI was 32.62 ± 8.59 kg/m2 . Most of the women did not have diabetes (n = 300 [74.0%]). The sample was primarily white (n = 165 [40.9%]) and Hispanic (n = 147 [36.5%]). The predicted weight of neonates at delivery (3677.07 ± 540.51 g) was higher than the actual birth weight (3335.92 ± 585.46 g). Based on regression analyses, as the BMI increased, so did the predicted weight (P < .01) and weight at delivery (P < .01). The accuracy of the estimated ultrasound-derived birth weight was not predicted by the maternal BMI (P = .22). Maternal race and diabetes status were not associated with the accuracy of ultrasound in predicting birth weight. CONCLUSIONS: Both predicted and actual birth weight increased as the BMI increased. However, the BMI did not affect the accuracy of the estimated ultrasound-derived birth weight. Maternal race and diabetes status did not influence the accuracy of the ultrasound-derived predicted birth weight.

Changes in Sonographically Measured Inferior Vena Caval Diameter in Response to Fluid Loading in Term Pregnancy.

OBJECTIVES: The purpose of this study was to determine whether the inferior vena caval (IVC) diameter is influenced by intravascular volume changes in pregnancy. METHODS: A prospective observational study was done on 2 groups of normal term gravidas. In 24 patients, we measured the IVC diameter, blood pressure, and heart rate (HR) before and after a 1-L fluid infusion in preparation for regional anesthesia, after initiation of an epidural block, and within 24 hours postpartum. In a second group of 15 women, we measured the IVC diameter sequentially during a 1-L crystalloid infusion. RESULTS: In the first group, the mean baseline IVC diameter ± SD at end-inspiration was 1.45 ± 0.32 cm, which was 19% smaller than at end-expiration (1.73 ± 0.31 cm; P= .003). This respiratory cycle variation remained significant at each measurement epoch. The mean caval diameter at end-inspiration increased by 23% after the fluid bolus (P = .012). Hydration was not, however, accompanied by any significant change in the HR, mean arterial pressure, or collapsibility index of the inferior vena cava. With epidural anesthesia, the mean arterial pressure decreased from 88 ± 9 to 80 ± 7 mm Hg (P= .018), but the HR and collapsibility index remained unchanged. Postpartum values were not significantly different from their baseline measurements, except for the mean arterial pressure, which was lower by about 6 mm Hg (P = .042). In the second group, the IVC diameter at end-inspiration increased by 31% after the 1-L infusion, and there was a positive correlation between the volume infused and the IVC diameter (r= 0.67; P< .0001). CONCLUSIONS: Measurable variations in the IVC diameter occur in response to volume changes in normal term pregnancy and postpartum.

Intrauterine Treatment of a Fetus with Familial Hypertrophic Cardiomyopathy Secondary to MYH7 Mutation.

There is no clear consensus on optimal management of fetuses affected by familial hypertrophic cardiomyopathy (HCM). Intrauterine treatment of the condition has not been attempted in any standardized fashion. We report the case of a fetus treated by maternal propranolol during the third trimester after septal hypertrophy and diastolic dysfunction was diagnosed on fetal echocardiogram. The pregnancy went successfully to term, and fetal septal hypertrophy was noted to improve prior to delivery.

Oxytocin utilization for labor induction in obese and lean women.

To determine if oxytocin dosage used for labor induction differed in obese and lean women, we analyzed records of patients who underwent term labor induction and delivered vaginally. Each of a cohort of 27 patients with a body mass index (BMI) >40 kg/m2 was matched with a patient with a BMI <28 kg/m2 for gestational age, for birth weight, and for cervical dilatation and fetal station at admission. The oxytocin dose administered during first stage labor was calculated for each patient. In addition to the matched characteristics, there was no difference between groups in parity, frequency of diabetes, epidural anesthesia use, or pharmacologic cervical ripening. Oxytocin utilization was significantly greater in obese women than in lean women. The maximum administration rate was 17.7±4.7 and 13.1±5.0 mU/min, respectively (P=0.001). Oxytocin administered per minute during the first stage of labor was greater in the obese group (11.6±4.8 vs. 8.6±4.1 mU/min; P=0.020). Neither active phase duration nor the maximum rate of dilatation differed significantly between the groups. That obese parturients required more oxytocin than lean women during the first stage of successful labor induction could not be explained by group differences in parity, birth weight, dysfunctional labor, pre-induction dilatation and station, or epidural use.

Comparison of patient attitudes and provider perceptions regarding medical student involvement in obstetric/gynecologic care.

BACKGROUND: Community physicians are becoming increasingly involved in clinical medical education. Some obstetrician/gynecologists have expressed reluctance to participate as clinical preceptors for medical students due to the sensitive nature of many of their patient encounters and concern for diminished patient satisfaction. PURPOSES: The purpose was to evaluate the willingness of community ob/gyn patients to participate in clinical medical education and to determine the accuracy of provider perceptions regarding this issue. METHODS: Surveys were distributed to women seeking ob/gyn care at 4 private practice sites in Tucson, Arizona. The surveys explored patient attitudes toward community physician involvement in clinical medical education as well as factors influencing personal willingness to include students as part of their healthcare team. Similar surveys were administered to the ob/gyn providers in those sites and evaluated their expectations of aggregate patient responses. RESULTS: Of 234 patient respondents, 87.6% believed that physicians have a responsibility to participate in medical education. Providers underestimated the number of patients for whom such participation would positively influence their personal provider choice (12.7% vs. 30.8%, p<.01) and overestimated negative (16.7% vs. 6.8%, p<.01) influence. Providers also underestimated acceptance rates of student pelvic examinations based on learner gender (13.8% vs. 24.3% male students, p=.01; 28.1% vs. 44.4% female students, p<.01). CONCLUSIONS: Patients in southern Arizona recognize and appreciate physicians' responsibility to educate future providers of women's healthcare. Providers may underestimate patient acceptance and value of students as part of their healthcare team. This bias may unnecessarily limit student exposure to clinical learning opportunities.

Medical faculty development: a modern-day odyssey.

Academic medical centers (AMCs) are pillars of the community; they provide health care, create jobs, educate biomedical professionals, and engage in research and innovation. To sustain their impact on human health, AMCs must improve the professional satisfaction of their faculty. Here, we describe ways to enhance recruitment, retention, creativity, and productivity of health science faculty.

Compensation in academic medicine: progress toward gender equity.

BACKGROUND: Studies have documented substantial salary disparities between women and men in academic medicine. While various strategies have been proposed to increase equity, to our knowledge, no interventions have been evaluated. OBJECTIVE: This paper aims to assess the effect of an identity-conscious intervention on salary equity. DESIGN: This study shows comparison of adjusted annual salaries for women and men before and after an intervention. PARTICIPANTS/SETTING: We studied full time faculty employed in FY00 (n = 393) and FY04 (n = 462) in one College of Medicine. INTERVENTION: Compensation data were obtained from personnel databases for women and men, and adjusted for predictors. After verification of data accuracy by departments, comparable individuals within the same department who had different salaries were identified. The Dean discussed apparent disparities with department heads, and salaries were adjusted. MEASUREMENTS: Total adjusted annualized salaries were compared for men and women for the year the project began and the year after the intervention using multivariate models. Female faculty members' salaries were also considered as a percent of male faculty members' salaries. RESULTS: Twenty-one potential salary disparities were identified. Eight women received equity adjustments to their salaries, with the average increase being $17,323. Adjusted salaries for women as a percent of salary for men increased from 89.4% before the intervention to 93.5% after the intervention. Disparities in compensation were no longer significant in FY2004 in basic science departments, where women were paid 97.6% of what men were paid. CONCLUSIONS: This study shows that gender disparities in compensation can be reduced through careful documentation, identification of comparable individuals paid different salaries, and commitment from leadership to hold the appropriate person accountable.

Gender differences in academic advancement: patterns, causes, and potential solutions in one US College of Medicine.

PURPOSE: The influx of women into academic medicine has not been accompanied by equality for male and female faculty. Women earn less than men in comparable positions, progress more slowly through academic ranks, and have not attained important leadership roles. This study tested hypotheses about why gender disparities exist in salary, rank, track, leadership, and perceptions of campus climate at one academic center, the University of Arizona College of Medicine, Tucson. METHOD: Salary, rank, and track data were obtained from institutional databases for the 1999-2000 fiscal year. A structured, online questionnaire was made available to 418 faculty members to collect information about their goals, attitudes, and experiences. RESULTS: A total of 198 faculty members completed the questionnaire. The data showed significant gender differences in faculty salaries, ranks, tracks, leadership positions, resources, and perceptions of academic climate. On average, women earned US dollars 12777 or 11% less than men, after adjusting for rank, track, degree, specialty, years in rank, and administrative positions (p <.0003). Of female faculty, 62% were assistant professors (49% of women were non-tenure-eligible assistant professors), while 55% of male faculty were promoted and tenured. Almost a third of women reported being discriminated against, compared with only 5% of men (p <.00001). CONCLUSION: Substantial gender differences in the rewards and opportunities of academic medicine remain, that can not be attributed to differences in productivity or commitment between women and men.

Optimal health and well-being for women: definitions and strategies derived from focus groups of women.

Women participating in focus groups were asked how they define health and well-being, and what strategies they would suggest for health optimization. Women defined health and well-being largely in terms of relationships. Their strategies for improving health involved enhancement of the quality of relationships with families, partners, and community. These proposed strategies included: creating a context for resilience; valuing and nurturing children, parents, and families; promoting interpersonal connections and community; realizing equality for women; and cultivating relational values. These perspectives can inform clinicians and health policy.
