Assessing the effects of age, gestation, socioeconomic status, and ethnicity on labor inductions

PURPOSE

To evaluate the likelihood of cesarean births, related to race, ethnicity, socioeconomic status (SES), maternal education and age, and gestational status for labor inductions on primiparous and multiparous women.

DESIGN AND METHODS

A retrospective descriptive correlational design was used with 1,325 women scheduled for induction at a large tertiary hospital in a southwestern U.S. state from January 1 through December 31, 2005. Birth outcomes were matched against inpatient hospital scheduling induction logs to verify the reason for induction, whether elective or clinically indicated.

FINDINGS

Age and gestation had nonlinear and significant associations with cesarean birth. Elective inductions for primiparous women significantly increased the likelihood of cesarean delivery. The independent effect of being a primiparous woman with an elective induction increased the probability of a cesarean birth by 50%, but this association was not significant for multiparous women. Mother's educational level was a significant predictor for cesarean births with multiparous women being induced. Ethnicity and SES did not increase the odds of cesarean delivery following labor induction for either primiparous women or multiparous women.

CONCLUSIONS

Elective inductions for primiparous women increased the probability of cesarean births. Elective labor induction for primiparous women should be offered with caution, particularly for women with advanced maternal age.

Detecting and treating depression among adolescents presenting for reproductive care: realizing opportunities

This article reviews typical symptoms of depression presented by adolescents in the reproductive care practice setting, provides an overview of the assessment process, and offers options for referral and/or treatment of this common, yet often unrecognized, mood disorder. Because females have a two-fold higher prevalence rate of depressive disorders as compared to males of the same age and because reproductive care providers have exceptional access to females during the early reproductive years, these physicians have a unique, but often unrealized, opportunity to detect and initiate treatment and/or referrals for depression in adolescent patients. Indeed, adolescents often discuss symptoms of depression with their reproductive care provider with an expectation that they will serve as a "first responder" in terms of assisting in the management of the depression. Thus, it is important that the provider have an understanding of the disorder, its symptoms, and possible treatment modalities. Reproductive care providers are uniquely qualified to identify, assess, and treat many types of mood disorders in adolescent females.

Pregnancy in renal transplant recipients

Women with renal disease face increasing infertility and high-risk pregnancy as they approach end-stage renal disease due to uremia. Renal transplantation has provided these patients the ability to return to a better quality of life, and for a number of women who are of child bearing age with renal disease, it has restored their fertility and provided the opportunity to have children. But, although fertility is restored, pregnancy in these women still harbors risk to the mother, graft, and fetus. Selected patients who have stable graft function can have successful pregnancies under the supervision of a multidisciplinary team involving maternal fetal medicine specialists and transplant nephrologists. Careful observation and management are required to optimize outcome for mother and fetus.

Providing pediatric palliative care: PACT in action

High-quality pediatric palliative care should be an expected standard in the United States, especially since the publication of the numerous position statements such as "Precepts of Palliative Care for Children and Adolescents and Their Families," a joint statement created by the Association of Pediatric Oncology Nurses, the National Association of Neonatal Nurses, and the Society of Pediatric Nurses. Although many barriers still exist, dedicated individuals and teams strive to promote models of excellence and improve care for children with life-threatening conditions and their families. The Pediatric Advanced Care Team, a joint project of Dana-Farber Cancer Institute and Children's Hospital, Boston, is one such interdisciplinary pediatric palliative care consultation service. Founded in 1997, we have grown and learned from formal study and our extensive clinical work with families, children, and our colleagues. This article describes our journey as an interdisciplinary team forging a new service within two renowned medical institutions in which historically the primary emphasis of care has been on cure and innovation. Although these values remain, our work has resulted in an increased acceptance of balancing treatment of the underlying disease or condition along with treatment of the physical, psychosocial, and spiritual needs of the child and family through life or death. One of our goals is to help promote a balance of hope for cure with hope for comfort, dignity, and integrity for every child and family.

Meaningful moments

Rituals provide meaning and order to transitions, and symbolically connect people and events. Despite the prevalence of perinatal loss (miscarriage, stillbirth, and newborn death) and pediatric deaths, little has been written about the use of rituals surrounding these losses. The purpose of this article is to define the dimensions of a ritual as each pertains to perinatal and pediatric death, and provide concrete applications for use in clinical practice. Intention, participation, and meaning-making are the key dimensions of rituals that arise from clinical encounters. Initiating the discussion about ritual and the timing of the ritual itself are critical elements for the nurse who is caring for a bereaved family. Because of the paucity of research on using rituals in perinatal and pediatric death, nurse researchers should design studies that explore the outcomes of using rituals, both in the short- and long-term, following the death.

Sudden infant death syndrome

Despite declines in prevalence during the past two decades, sudden infant death syndrome (SIDS) continues to be the leading cause of death for infants aged between 1 month and 1 year in developed countries. Behavioural risk factors identified in epidemiological studies include prone and side positions for infant sleep, smoke exposure, soft bedding and sleep surfaces, and overheating. Evidence also suggests that pacifier use at sleep time and room sharing without bed sharing are associated with decreased risk of SIDS. Although the cause of SIDS is unknown, immature cardiorespiratory autonomic control and failure of arousal responsiveness from sleep are important factors. Gene polymorphisms relating to serotonin transport and autonomic nervous system development might make affected infants more vulnerable to SIDS. Campaigns for risk reduction have helped to reduce SIDS incidence by 50-90%. However, to reduce the incidence even further, greater strides must be made in reducing prenatal smoke exposure and implementing other recommended infant care practices. Continued research is needed to identify the pathophysiological basis of SIDS.

Cord serum concentrations of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in relation to weight and size at birth

BACKGROUND

Recent studies have reported developmental toxicity among rodents dosed with perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA).

OBJECTIVES

We examined the relationship between concentrations of PFOS and PFOA in cord serum (surrogates for in utero exposures) and gestational age, birth weight, and birth size in humans.

METHODS

We conducted a hospital-based cross-sectional epidemiologic study of singleton deliveries in Baltimore, Maryland. Cord serum samples (n = 293) were analyzed for PFOS and PFOA by online solid-phase extraction, coupled with reversed-phase high-performance liquid chromatography-isotope dilution tandem mass spectrometry. Maternal characteristics and anthropometric measures were obtained from medical charts.

RESULTS

After adjusting for potential confounders, both PFOS and PFOA were negatively associated with birth weight [per ln-unit: beta = -69 g, 95% confidence interval (CI), -149 to 10 for PFOS; beta = -104 g, 95% CI, -213 to 5 for PFOA], ponderal index (per ln-unit: beta = -0.074 g/cm(3) x 100, 95% CI, -0.123 to -0.025 for PFOS; beta = -0.070 g/cm(3) x 100, 95% CI, -0.138 to -0.001 for PFOA), and head circumference (per ln-unit: beta = -0.32 cm, 95% CI, -0.56 to -0.07 for PFOS; beta = -0.41 cm, 95% CI, -0.76 to -0.07 for PFOA). No associations were observed between either PFOS or PFOA concentrations and newborn length or gestational age. All associations were independent of cord serum lipid concentrations.

CONCLUSIONS

Despite relatively low cord serum concentrations, we observed small negative associations between both PFOS and PFOA concentrations and birth weight and size. Future studies should attempt to replicate these findings in other populations.

Parent and child perspectives on physician communication in pediatric palliative care

Objective:

Despite growing recognition of the importance of communication with children with life-limiting illnesses and their families, there has been limited research that includes the child's perspective. The purpose of the current study was to identify the aspects of physician communication that children with life-limiting illnesses and their parents perceived to be facilitative or obstructive in pediatric palliative care.

Methods:

This qualitative study reports on the first 20 parent and child pairs of pediatric oncology and cardiology patients (mean age 14.25 years, range 9-21 years) with a poor prognosis (physician reported likely <20% chance of survival beyond 3 years) from two children's hospitals and one pediatric hospice in Los Angeles, California. Perspectives on physician communication were elicited from children's and parents' individual narratives, recorded, coded, and analyzed using qualitative grounded theory methodology.

Results:

Both children and parents identified five domains of physician communication deemed to be highly salient and influential in quality of care. These included relationship building, demonstration of effort and competence, information exchange, availability, and appropriate level of child and parent involvement. Parents identified coordination of care as another important communication domain. The characteristics of physicians that were deemed most harmful to satisfying communication included having a disrespectful or arrogant attitude, not establishing a relationship with the family, breaking bad news in an insensitive manner, withholding information from parents and losing their trust, and changing a treatment course without preparing the patient and family.

Significance of results:

The six positive communication domains are areas for clinicians to recognize and monitor in communicating with children and families in the pediatric palliative care setting. Knowledge of the qualities of communication that are satisfying to and valued by children and their parents have the potential to lead to more effective communication around the difficult decisions faced by physicians, parents, and children with life-threatening conditions.

Postdischarge infant mortality among very low birth weight infants: a population-based study

OBJECTIVE

The objective of this study was to identify factors that were associated with death after discharge from the NICU of very low birth weight infants in a population-based study.

METHODS

From a national cohort of 13,430 very low birth weight infants who were born in Israel from 1995 to 2003, 10,602 infants were discharged from the hospital and composed the study population. Demographic and clinical data regarding the pregnancy, delivery, and neonatal course were obtained from the Israel national very low birth weight infant database. Data on each case of death during the postdischarge period until 1 year of age were provided by the Ministry of Health from national linked birth and death certificates. Univariate analyses and a multivariable logistic regression analyses were performed to examine the perinatal and neonatal risk factors for postdischarge death.

RESULTS

The postdischarge mortality rate was 7.5 per 1000 (80 of 10,602 infants discharged from the hospital). The death rate was significantly higher in non-Jewish infants, infants who were born to young mothers, and infants who were born to low-educated mothers. After adjustment for demographic characteristics and perinatal and neonatal variables, postdischarge mortality was independently associated with congenital malformations, neonatal seizures, necrotizing enterocolitis, and bronchopulmonary dysplasia.

CONCLUSION

Although the postdischarge death rate was relatively low in our cohort of very low birth weight infants, attention should be focused on the subgroups of infants who are at higher risk to decrease their mortality further.

Trial of Labor After One Previous Cesarean Delivery for Multifetal Gestation

OBJECTIVE

To estimate success rates and risks with a trial of labor after one previous cesarean delivery for multifetal gestation compared with one previous cesarean delivery for a singleton pregnancy.

METHODS

Patients from the National Institute of Child Health and Human Development Maternal Fetal Medicine Units Network Cesarean Registry with one previous cesarean delivery and a current term singleton pregnancy were identified. Cases had one previous cesarean delivery for a multifetal pregnancy. Controls had one previous cesarean delivery for a singleton pregnancy.

RESULTS

Of cases, 556 of 944 (58.9%) attempted a trial of labor. Of controls, 13,923 of 29,329 (47.5%) attempted a trial of labor. The trial of labor success rate was 85.6% among cases and 73.1% among controls (odds ratio 2.19, 95% confidence interval 1.72-2.78). Compared with trial of labor controls, cases had no statistically increased risk of transfusion, endometritis, intensive care unit admissions, uterine rupture, or perinatal complications. Cases in this analysis with a successful trial of labor were more likely to have previously had a successful vaginal birth after cesarean (37.1% compared with 14.1%, P<.001).

CONCLUSION

Women with one previous cesarean delivery for a multifetal gestation have high trial of labor success rates and low complication rates.

Palliative care for the family carrying a fetus with a life-limiting diagnosis

Prenatal diagnosis of a lethal anomaly is a monumental moment in a family's life. It requires extensive team counseling and planning about complex neonatal and obstetric medical management. The construct of palliative care with its focus on emotional, spiritual, social, and symptom support can provide a model for caring for these families.

Mortality of full-term infants during the first month of life in a tertiary care hospital

OBJECTIVE

The neonatal mortality rate is disproportionately influenced by preterm infants and does not reflect the rate in full-term infants. Our objectives were to estimate the full-term neonatal mortality rate and to identify causes of death in full-term infants during the first month of life.

STUDY DESIGN

A retrospective study of full-term infant deaths during a 6-year period from 2000 to 2005, in a tertiary medical center.

RESULT

During the study period there were 44,703 full-term births and 31 deaths, representing a mortality rate of 0.69 per 1,000 live births. The main cause of death was congenital anomalies (64.5%), specifically cardiac anomalies. Other causes were chromosomal anomalies or syndromes (12.9%), labor complications (12.9%), infections (3.2%), congenital diseases (3.2%) and metabolic disorders (3.2%).

CONCLUSION

The mortality rate of full-term infants may be lower than previous estimates. Efforts aimed at decreasing mortality among full-term infants should focus on prenatal diagnosis.

The ambulatory pediatric association fellowship in pediatric environmental health: a 5-year assessment

BACKGROUND

Evidence is mounting that environmental exposures contribute to causation of disease in children. Yet few pediatricians are trained to diagnose, treat, or prevent disease of environmental origin.

OBJECTIVES

To develop a cadre of future leaders in pediatric environmental health (PEH), the Ambulatory Pediatric Association (APA) launched a new 3-year fellowship in 2001-the world's first formal training program in PEH. Sites were established at Boston Children's Hospital, Mount Sinai School of Medicine, George Washington University, University of Cincinnati, and University of Washington. Fellows are trained in epidemiology, biostatistics, toxicology, risk assessment, and preventive medicine. They gain clinical experience in environmental pediatrics and mentored training in clinical research, policy development, and evidence-based advocacy. Thirteen fellows have graduated. Two sites have secured follow-on federal funding to enable them to continue PEH training.

DISCUSSION

To assess objectively the program's success in preparing fellows for leadership careers in PEH, we conducted a mailed survey in 2006 with follow-up in 2007.

CONCLUSIONS

Fifteen (88%) of 17 fellows and graduates participated; program directors provided information on the remaining two. Nine graduates are pursuing full-time academic careers, and two have leadership positions in governmental and environmental organizations. Ten have published one or more first-authored papers. Seven graduates are principal investigators on federal or foundation grants. The strongest predictors of academic success are remaining affiliated with the fellowship training site and devoting < 20% of fellowship time to clinical practice.

CONCLUSION

The APA fellowship program is proving successful in preparing pediatricians for leadership careers in PEH.

Acculturation and cigarette smoking among pregnant Hispanic women residing in the United States

OBJECTIVES

We explored whether higher levels of acculturation were associated with higher rates of cigarette smoking among pregnant Hispanic women residing in the United States.

METHODS

We evaluated data from the Latina Gestational Diabetes Mellitus Study, a prospective study of 1231 Hispanic prenatal care patients conducted from 2000 to 2004 in Massachusetts. Self-reported data on acculturation, cigarette smoking, and covariates were collected by bilingual interviewers using a questionnaire. We conducted logistic regression multivariate analyses to examine the impact of acculturation level on the odds of smoking.

RESULTS

Overall, 21% of women reported smoking during pregnancy. Acculturation was associated with elevated smoking rates in pregnant Hispanic women. US-born Hispanic women who preferred English had more than twice the odds of smoking compared with Puerto Rican or foreign-born Hispanic women who preferred Spanish (odds ratio [OR]=2.76, 95% confidence interval [CI] 1.36, 5.63).

CONCLUSIONS

Our findings suggest that higher-acculturated Hispanic women living in the United States are more likely to smoke cigarettes during pregnancy than are less-acculturated Hispanic women. These results will inform interventions aimed at reducing cigarette smoking during pregnancy among US Hispanic women.

Do socioeconomic factors explain why maternal smoking during pregnancy is more frequent in a more developed city of Brazil?

The prevalence of smoking during pregnancy in Ribeirão Preto, a rich Brazilian city, was significantly higher (21.4%) than in São Luís (5.9%), a less developed city. To assess which variables explain the difference in prevalence of smoking during pregnancy, data from two birth cohorts were used, including 2846 puerperae from Ribeirão Preto, in 1994, and 2443 puerperae from São Luís, in 1997/98. In multivariable analysis, risk of maternal smoking during pregnancy was higher in São Luís for mothers living in a household with five or more persons (OR = 1.72, 95%CI = 1.12-2.64), aged 35 years or older (OR = 1.98, 95%CI = 0.99-3.96), who had five or more children (OR = 2.10, 95%CI = 1.16-3.81), and whose companion smoked (OR = 2.20, 95%CI = 1.52-3.18). Age of less than 20 years was a protective factor (OR = 0.55, 95%CI = 0.33-0.92). In Ribeirão Preto there was association with maternal low educational level (OR = 2.18, 95%CI = 1.30-3.65) and with a smoking companion (OR = 3.25, 95%CI = 2.52-4.18). Receiving prenatal care was a protective factor (OR = 0.24, 95%CI = 0.11-0.49). Mothers from Ribeirão Preto who worked outside the home were at a higher risk and those aged 35 years or older or who attended five or more prenatal care visits were at lower risk of smoking during pregnancy as compared to mothers from São Luís. Smoking by the companion reduced the difference between smoking rates in the two cities by 10%. The socioeconomic variables in the model did not explain the higher prevalence of smoking during pregnancy in the more developed city.

Recent trends in erythropoietin-mediated neuroprotection

Fifteen years of evidence have established that the cytokine erythropoietin offers promise as a treatment for brain injury. In particular, neonatal brain injury may be reduced or prevented by early treatment with recombinant erythropoietin. Extreme prematurity and perinatal asphyxia are common conditions associated with poor neurodevelopmental outcomes including cerebral palsy, mental retardation, hearing or visual impairment, and attention deficit hyperactivity disorder. When high doses of erythropoietin are administered systemically, a small proportion crosses the blood-brain barrier and can protect against hypoxic-ischemic brain injury. In addition to other protective effects, erythropoietin can specifically protect dopaminergic neurons. Since reduced dopamine neurotransmission contributes to attention deficit hyperactivity disorder, this condition may be amenable to erythropoietin treatment. This review focuses on the potential application of erythropoietin as a neuroprotectant with regard to neurologic complications of extreme prematurity, including attention deficit hyperactivity disorder. Recent concerns that early erythropoietin might exacerbate the pathologic neovascularization associated with retinopathy of prematurity are addressed.

Perinatal Disparities for Black Mothers and Their Newborns

OBJECTIVES

In the United States, significant ethnic and racial health and healthcare disparities exist among our most vulnerable populations, new mothers and newborns. We sought to determine disparities in socioeconomic status, perinatal health, and perinatal healthcare for black mothers and their newborns cared for in well-baby nurseries compared with white mother/baby pairs in Pennsylvania.

METHODS

A retrospective analysis of a merged data set containing birth and clinical discharge records was conducted. Perinatal data from 44,105 black mothers and their singleton newborns, > or = 35 weeks gestational age cared for in Pennsylvania well-baby nurseries from 1998-2002 were compared with 88,210 white mother/baby pairs.

RESULTS

Black mothers were younger and were much more likely to receive Medicaid or be uninsured compared with white mothers. They were less likely to be college-educated, married, or have prenatal care beginning in the first trimester. Infants born to black mothers were less likely to be delivered via Cesarean section, but were more likely to be born between 35 and 38 weeks gestation and be of low birth weight.

CONCLUSIONS

Numerous significant disparities exist for black mothers and their newborns cared for in well-baby nurseries in Pennsylvania. Since most newborns are cared for in this setting as opposed to intensive care environments, recognition of the differences that exist for this group when compared to well newborns of white mothers can help to improve healthcare and its delivery to this population. Federal and local initiatives must continue efforts to eliminate racial disparities.

Diagnostic Accuracy of Cervicovaginal Interleukin-6 and Interleukin-6:Albumin Ratio as Markers of Preterm Delivery

Background: Absence of fetal fibronectin (fFN) in the cervicovaginal fluid (CVF) of women with symptoms of preterm labor is an excellent predictor of women who will not deliver within 2 weeks of testing. Preliminary studies suggest interleukin (IL)-6 performs similarly to fFN. The positive predictive values of both these assays are poor. Inconsistent specimen collection may explain this poor performance. The objective of this study was to validate the clinical utility of cervicovaginal IL-6 and investigate the utility of the IL-6:albumin ratio to predict delivery within 14 days.

Methods: We quantified albumin and IL-6 with the DPC Immulite® in 660 CVF specimens collected for physician-ordered fFN analysis. The clinical utility of IL-6 and IL-6:albumin to predict delivery within 14 days of collection was determined.

Results: The sensitivity, specificity, and positive and negative likelihood ratios for delivery within 14 days were 65%, 87%, 4.8, and 0.4, respectively, for fFN and 35%, 91%, 3.8, and 0.7 for IL-6, with a 250 ng/L cutoff. With a preterm delivery prevalence of 4.7%, positive and negative predictive values were 19% and 98%, respectively, for fFN and 16% and 97% for IL-6. The areas under the ROC curves were 0.71 and 0.51 for IL-6 and IL-6:albumin, respectively. Odds ratios for delivery within 14 days of collection were 11.8 (P &lt;0.0001), 5.5 (P = 0.0001), and 2.4 (P = 0.06) for fFN, IL-6, and IL-6:albumin, respectively.

Conclusions: Cervicovaginal IL-6 may have utility for predicting preterm labor while offering the potential for substantial cost savings. Assay performance characteristics are not improved by normalizing IL-6 to albumin.

Infant end-of-life care: the parents' perspective

OBJECTIVE

The purpose of this study was to identify factors important to parents in their infant's end-of-life care.

STUDY DESIGN

Participants were parents (n=19 families) whose infant (less than 1 year old) had died. Parents completed the Revised Grief Experience Inventory (RGEI) and a semi-structured interview regarding their infant's end-of-life care. Interviews were rated using the Post-Death Adaptation Scale (PDAS).

RESULTS

Parents scored significantly lower than the normative sample on the RGEI, and PDAS scores suggested that these parents were adapting positively. Parent interviews identified the aspects of care that were important to parents: honesty, empowered decision-making, parental care, environment, faith/trust in nursing care, physicians bearing witness and support from other hospital care providers.

CONCLUSIONS

Results of this study suggest that parents can effectively cope following the death of an infant and the medical staff can do much to improve the end-of-life care for infants and their families.

Ethnic/racial diversity, maternal stress, lactation and very low birthweight infants

OBJECTIVE

(1) To compare maternal characteristics and psychological stress profile among African-American, Caucasian and Hispanic mothers who delivered very low birthweight infants. (2) To investigate associations between psychosocial factors, frequency of milk expression, skin-to-skin holding (STS), and lactation performance, defined as maternal drive to express milk and milk volume.

STUDY DESIGN

Self-reported psychological questionnaires were given every 2 weeks after delivery over 10 weeks. Milk expression frequency, STS, and socioeconomic variables were collected.

RESULT

Infant birthweight, education, and milk expression frequency differed between groups. Trait anxiety, depression and parental stress in a neonatal intensive care unit (PSS:NICU) were similar. African-American and Caucasian mothers reported the lowest scores in state anxiety and social desirability, respectively. Maternal drive to express milk, measured by maintenance of milk expression, correlated negatively with parental role alteration (subset of PSS:NICU) and positively with infant birthweight and STS. Milk volume correlated negatively with depression and positively with milk expression frequency and STS.

CONCLUSION

Differences between groups were observed for certain psychosocial factors. The response bias to self-reported questionnaires between groups may not provide an accurate profile of maternal psychosocial profile. With different factors correlating with maintenance of milk expression and milk volume, lactation performance can be best enhanced with a multi-faceted intervention program, incorporating parental involvement in infant care, close awareness and management of maternal mental health, and encouragement for frequent milk expression and STS.

Effect of the Washington Special Supplemental Nutrition Program for Women, Infants and Children (WIC) on Pregnancy Outcomes

OBJECTIVES

We determined the effect of the Washington State Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on adverse pregnancy outcomes.

METHODS

We used a record-linkage retrospective cohort design. We matched records of eligible women who enrolled in Washington WIC from 9/1/1999-12/31/2000 to records of their subsequent birth/fetal death from the Washington State Department of Health to determine their pregnancy outcome between 9/1/1999-10/15/2001 (N = 42,495). We selected comparison women from birth/fetal death records who were WIC-eligible but not on WIC (N = 30,751). We used unconditional logistic regression for analysis.

RESULTS

WIC was protective for preterm delivery depending on history of abortion and adequacy of prenatal care, being most protective for women with abortion and inadequate prenatal care (Odds ratio (OR) = 0.4; 95% confidence interval (CI) = 0.3-0.5). WIC was protective for low birth weight depending on women's cervical health, with most protection conferred to those with incompetent cervix (OR = 0.2; 95% CI = 0.1-0.6). WIC was protective for fetal death depending on women's education, being most protective to those with <12 years of education (OR = 0.2; 95% CI = 0.1-0.3).

CONCLUSIONS

WIC is protective for adverse pregnancy outcomes especially for high risk women.

Using linked data to assess patterns of early intervention (EI) referral among very low birth weight infants

OBJECTIVES

Access to Early Intervention (EI) services may improve cognitive and behavioral outcomes in very low birth weight infants, but few states have population-based data to evaluate EI outreach efforts. We analyzed Massachusetts (MA) infants born weighing <1,200 g to identify maternal and birth characteristics that predicted EI referral and timing of referral.

METHODS

MA birth and hospital discharge records (Jan. 1998-Sept. 2000) were linked to EI referral records (Jan. 1998-Sept. 2003) via probabilistic and deterministic methods (88% linkage). Timing of EI referral among infants weighing <1,200 g was examined by infant and maternal characteristics using categorical (0-12 months, 12-36 months, or no referral) time comparisons in the crude analysis. Survival functions calculating median time to referral, and adjusted hazard ratios (HR) with 95% confidence intervals (CI) were calculated for continuous time comparisons of EI referral from birth to 36 months.

RESULTS

Of 1,233 infants weighing <1,200 g, 93.2% were referred to EI. After risk adjustment, referral was more likely among multiple-birth infants (HR = 1.17, 95%CI 1.06-1.30) and less likely among infants <28 weeks (HR = 0.70; 95%CI 0.64-0.77) or with low Apgar scores (<5 at 5 min; HR = 0.75; 95%CI 0.62-0.92). EI referrals were lower for infants of black non-Hispanic mothers, and mothers without private insurance (HR = 0.85; 95%CI 0.74-0.98 and HR = 0.77; 95%CI 0.68-0.86, respectively).

CONCLUSIONS

In MA, most infants born <1,200 g are referred to EI, but disparities exist. Analysis of linked population-based health and developmental services can inform programs in order to reduce disparities and improve access for all high-risk infants.

Increasing use of antidepressants in pregnancy

OBJECTIVE

The purpose of this study was to quantify the rate of exposures to antidepressants during pregnancy in a large cohort of women.

STUDY DESIGN

This was a retrospective cohort study of 105,335 pregnancies among women enrolled in Tennessee Medicaid from 1999-2003. Pregnancies were classified according to antidepressant exposures during pregnancy using previously validated computerized pharmacy records linked with birth certificates.

RESULTS

During the study period, 8.7% of women giving birth had exposure to any antidepressant; 6.2% had exposure to a selective serotonin reuptake inhibitor. Maternal age > 25 years (P < .0001), white race (P < .0001), and education > 12 years (P = .008) were significant predictors of antidepressant exposure. The proportion of pregnancies with antidepressant use increased from 5.7% of pregnancies in 1999 to 13.4% of pregnancies in 2003 (p < .0001). The increase was mostly accounted for by increases in selective serotonin reuptake inhibitor exposures.

CONCLUSION

There is an urgent need for further studies that better quantify the fetal consequences of exposure to antidepressants.

Rising infant mortality in Delaware: an examination of racial differences in secular trends

OBJECTIVES

Recent increases in the Delaware Infant Mortality Rate (IMR) have been attributed to a rise in the mortality of very low birth weight (VLBW, <1500 g) infants born to mothers of higher socioeconomic status. This study examines whether the determinants of infant mortality trends in Delaware vary by race.

METHODS

Linked birth/infant death cohort files for the two periods 1993-1997 and 1998-2002 were used to evaluate the determinants of infant mortality trends separately for White and Black racial groups. Kitagawa analyses determined the components of race-specific infant mortality trends attributable to changes in both the birthweight distribution and birthweight-specific mortality rates. Maternal characteristics were examined to identify factors associated with IMR changes.

RESULTS

Between the two time periods, infant mortality increased 23% among White infants and 17% among Black infants. For both races, the infant mortality increase was explained by increases in the incidence and mortality of VLBW infants, specifically below <500 grams for Blacks and <1,000 grams for Whites. The increased incidence of VLBW deliveries was statistically significant only among Whites, almost 40% of which was explained by an increase in multiple births. For both Whites and Blacks, the increase in VLBW mortality occurred mainly among births to more traditionally advantaged women who were twenty or older, at least high school educated, married, privately insured, had received first trimester prenatal care, and those who delivered multiple births.

CONCLUSIONS

These findings suggest that conventional strategies of increasing access to prenatal care among disadvantaged women may be insufficient to reverse recent IMR increases in Delaware, irrespective of race. Future efforts should focus on understanding the causes of the increased infant mortality associated with higher socioeconomic status, including changes in assisted reproductive technology utilization, maternal health status, and obstetric practice.

Proteomic biomarkers of intra-amniotic inflammation: relationship with funisitis and early-onset sepsis in the premature neonate

Our goal was to determine the relationship between 4 amniotic fluid (AF) proteomic biomarkers (human neutrophil defensins 2 and 1, calgranulins C and A) characteristic of intra-amniotic inflammation, and funisitis and early-onset sepsis in premature neonates. The mass restricted (MR) score was generated from AF obtained from women in preterm labor (n = 123). The MR score ranged from 0-4 (none to all biomarkers present). Funisitis was graded histologically and interpreted in relation to the MR scores. Neonates (n = 97) were evaluated for early-onset sepsis. There was significant correlation between the severity of AF inflammation and the presence (53/123) and grades of funisitis (p < 0.001). Funisitis occurred independently of the amniocentesis-to-delivery interval or status of the membranes and was best predicted by an MR score 3-4 and an earlier gestational age (GA) at delivery. Neonates born to women with an MR score 3-4 had an increased incidence of suspected/confirmed sepsis, even after adjusting for GA at birth. Calgranulin C had the highest association with clinically significant funisitis, while calgranulin A had the strongest association with early-onset sepsis. To conclude, AF proteomic analysis shows that women with MR scores 3-4 are more likely to have histologic funisitis, and deliver neonates with early-onset sepsis.

When the spirit leaves: Childhood death, grieving, and bereavement in Islam

The death of a child has a profound and often long-lasting impact on families. The parent's relationship and their ability to bond with and take care of surviving children may be affected. It is important for healthcare workers to understand the dynamics associated with bereavement, especially when the family comes from a non-Western culture. Islam is one of the three most populous religions along with Christianity and Hinduism and the fastest growing religion in the United States but remains largely misunderstood. This paper seeks to explain what Islam is, who is a Muslim, where they live, and what they believe and practice. It also explains how Islamic beliefs contextualize the meaning of life and death for Muslims and how they are exhorted to grieve upon a child's death. Reading this paper will enable those who care for Muslim families to better attend to the social and emotional needs of Muslim parents and siblings after such a tragic event.

Case-control analysis of endemic Serratia marcescens bacteremia in a neonatal intensive care unit

BACKGROUND

Serratia marcescens is an opportunistic gram-negative rod which typically infects compromised hosts.

OBJECTIVES

To identify risk factors, signs, and outcomes associated with non-epidemic S marcescens bacteremia in a neonatal intensive care unit (NICU).

METHODS

The records of infants with S marcescens bacteremia while in the Yale-New Haven Hospital NICU from 1980-2004 were reviewed. A matched case-control study was performed by comparing each case of S marcescens to 2 uninfected controls and 2 cases of Escherichia coli bacteremia.

RESULTS

Twenty-five sporadic cases of S marcescens bacteremia were identified. Eleven available isolates were determined to be different strains by pulse field gel electrophoresis. Infants with S marcescens bacteremia had median gestational age and birth weight of 28 weeks and 1235 grams, respectively. Compared to matched, uninfected controls, infants with S marcescens bacteremia were more likely to have had a central vascular catheter (OR = 4.33; 95% CI (1.41 to 13.36)) and surgery (OR = 5.67; 95% CI (1.81 to 17.37)), and had a higher overall mortality (44% vs 2%; OR = 38.50; 95% CI (4.57 to 324.47)). Compared to E coli matched controls, infants with S marcescens bacteremia had later onset of infection (median of 33 days of life vs 10; p<0.001), prolonged intubation (OR = 5.76; 95% CI (1.80 to 18.42)), and a higher rate of CVC (OR = 7.77; 95% CI (2.48 to 24.31)) use at the time of infection. A higher rate of meningitis (24% vs 7%; OR = 3.98; 95% CI (1.09 to 14.50)) was observed with S marcescens bacteremia compared to E coli.

CONCLUSIONS

S marcescens bacteremia occurs sporadically in the NICU, primarily in premature infants requiring support apparatus late in their hospital course. Associated meningitis is common and mortality high.

Infant mortality: explaining black/white disparities in Wisconsin

OBJECTIVES

Understanding the factors contributing to black/white disparities in infant mortality rates in Wisconsin is a prerequisite to decreasing these disparities and improving birth outcomes. We examined multiple determinants of infant mortality to understand the impact of specific risk factors on the infant mortality rates of blacks and whites in Wisconsin.

METHODS

We used the Wisconsin Interactive Statistics on Health database to examine infant mortality data for the 5-year time period, 1998-2002 (N=32,166 black infant births; 272,559 white infant births). We conducted a bivariate analysis of relative risks (RR) of infant mortality (black vs. white) using specific variables available in the database. We then examined the relationship between infant mortality rate and selected risk factors using regression analyses.

RESULTS

Unadjusted, black infants were 3.0 times more likely to die during their first year of life, compared with white infants. Adjusting for gestational age black infants were only 1.9 times more likely to die. The risk was further reduced, after adjusting for birth weight, to 1.3. However, stratifying and adjusting for 8 other multiple variables accounted for some, but not all of the disparity. Black infants who had the same risk profile as white infants still had a 2-fold excess risk of death. In addition, simultaneously controlling for 4 of the 8 risk factors (maternal age, maternal education, adequacy of prenatal care received, and region of the state) also reduced, but did not eliminate, this excess risk (RR was still 2.2 for black infants). Independent of maternal age and region of the state, adequate prenatal care and higher levels of education are significant indicators of the racial disparity between whites and blacks.

CONCLUSIONS

These results suggest that, within a given racial group, increasing access to prenatal care and increasing maternal educational attainment will improve infant mortality rates but will not eliminate the black/white disparity in infant mortality. In fact, these interventions may actually widen the disparity in infant mortality rate between blacks and whites, especially if funds and programs are applied equally throughout the population, rather than targeted to high-risk individuals, who lag significantly behind the majority population. The Wisconsin white population, which has already attained an infant mortality rate of 4.5 per 1,000 live births, will continue to have greatest benefit from these programs compared to blacks who have a rate of 19.2 in 2004; thus, the disparity is not eliminated and the gap widens probably due to differential uptake of health messages secondary to health literacy issues. Further research is needed to fully understand the additional, more difficult to measure factors that contribute significantly to infant mortality, especially among black women.

Efficacy of a SIDS risk factor education methodology at a native American and Caucasian site

OBJECTIVE

To complete a community based efficacy study of a SIDS risk reduction methodology.

METHODS

We utilized two community sites for this study: 1) a Native American home visiting program for pregnant and young mothers; and 2) an obstetrics department in a community hospital. Pre and posttests were used to measure learning. The risk reduction intervention was delivered by hospital nurses or the home visiting staff and required about 20 minutes. Each of the nine risk factors was discussed.

RESULTS

We completed paired pre and post testing with 341 women. The pre tests found substantial knowledge deficits about SIDS risk factors in both groups. The pre and posttest changes for the nine risk factors ranged from 5% to 74%. Participants from both groups demonstrated nearly equivalent rates of learning for all nine of the risk concepts.

CONCLUSION

This study demonstrated the efficacy of this brief intervention program. The program was effective in increasing parental knowledge of the risk factors targeted by this study in both settings. The magnitude of change supports additional research with this program in other settings and with additional populations.

Antibiotic-resistant organisms in the neonatal intensive care unit

Neonates, particularly those born prematurely, are at an increased risk of bacterial infection. Empiric treatment with antimicrobials occurs frequently in the neonatal intensive care unit (NICU). Repeated and/or prolonged courses of antibiotic exposure have resulted in an increase in the prevalence of hospital-acquired, antibiotic-resistant organisms such as methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, and multidrug-resistant Gram-negative rods. As bacterial strains become increasingly resistant to standard antimicrobial therapy, measures to control and prevent this problem are essential. Current efforts have focused on monitoring and restricting the use of antimicrobials, proper hand hygiene, evaluation of potential reservoirs of bacterial acquisition and transmission, cohorting and isolation of colonized infants, decolonization strategies, and fostering of effective inter- and intrahospital communication.

Neonatal urinary cotinine correlates with behavioral alterations in newborns prenatally exposed to tobacco smoke

Altered behavior due to prenatal smoke exposure was examined in 25 neonates born from smoking mothers who consumed at least 5 cigarettes/d during the entire gestation. Data were compared with 25 matched neonates born from nonsmoking mothers. Neonatal behavior was evaluated using the Brazelton Neonatal Behavioral Assessment Scale (BNBAS). Antenatal exposure to tobacco smoke at the end of the pregnancy was determined by measurement of urinary cotinine. Newborns from smoking mothers showed significant lower scores in various BNBAS items compared with neonates from nonsmoking mothers. A strong correlation was observed between infant irritability and urinary cotinine in newborns from smoker and nonsmoking mothers and with number of daily smoked cigarettes and maternal nicotine daily intake of infants exposed to active maternal smoking. Linear regression analysis showed that urinary cotinine was the best predictor of infant irritability (r(2) = 0.727). The latter was also associated to the neonate's low level of attention and poor response to inanimate auditory stimuli. Among infants from nonsmoking mothers, paternal smoking significantly correlated with infant urinary cotinine and infant irritability, being also the best predictor of irritability (r(2) = 0.364). Neonatal behavior can be significantly altered in a dose-dependent manner even after modest prenatal exposure to tobacco smoke.

Incidence and determinants of peripartum hysterectomy

OBJECTIVE

Most studies of peripartum hysterectomy are conducted in single institutions, limiting the ability to provide national incidence estimates and examine risk factors. The objective of this study was to provide a national estimate of the incidence of peripartum hysterectomy and to examine factors associated with the procedure.

METHODS

We used data for 1998-2003 from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample, an annual nationally representative survey of inpatient hospitalizations. Peripartum hysterectomy was defined as a hysterectomy and delivery occurring during the same hospitalization. Odds ratios (ORs) and 95% confidence intervals (CIs) were adjusted for maternal and hospital characteristics using logistic regression.

RESULTS

During 1998-2003, an estimated 18,339 peripartum hysterectomies occurred in the United States (0.77 per 1,000 deliveries). Compared with vaginal delivery without a previous cesarean delivery, the ORs of peripartum hysterectomy for other delivery types were as follows: repeat cesarean, 8.90 (95% CI 8.09-9.79); primary cesarean, 6.54 (95% CI 5.95-7.18); and vaginal birth after cesarean, 2.70 (95% CI 2.23-3.26). Multiple births were associated with an increased risk compared with singleton births (OR 1.41, 95% CI 1.16-1.71).

CONCLUSION

Our results suggest that vaginal birth after cesarean, primary and repeat cesarean deliveries, and multiple births are independently associated with an increased risk for peripartum hysterectomy. These findings may be of concern, given the increasing rate of both cesarean deliveries and multiple births in the United States.

Geographic variations in outcome of very low birth weight infants in Italy

AIM

A number of social and health aspects in Italy show remarkable geographic dishomogeneity. We investigated if this phenomenon involves the outcome of very low birth-weight infants (VLBWI).

METHODS

This is a multi-centre nation-based survey among all Italian NICUs. The number of VLBWI admitted to each NICU in 2001 by birth-weight classes of 250 g, their inborn/outborn status and survival at discharge were registered through ad hoc questionnaires. The data were analysed for the whole country and for three geographic areas (North, Centre and South).

RESULTS

A total of 4679 VLBWI in 125 units were surveyed (0.88% of live births in Italy in 2001). The median number of infants admitted was 34 per NICU (interquartile range 16,52), without significant differences among the three geographic areas. The inborn rate was 80.7% (86.5% in the North, 83.7% in the Centre and 74.6% in the South). The mortality rate was 19.6% (15.6% in the North, 19.3% in the Centre and 23.4% in the South). Adjusted relative risk of death between Southern and Northern regions was 1.48 (95% CI 1.30-1.68), and that between outborn and inborn infants was 1.20 (95% CI 1.04-1.37).

CONCLUSIONS

The differences in mortality among geographic areas suggest a state of socio-sanitary deprivation in the Southern regions, as well as different models of organisation and quality of perinatal care.

Racial/ethnic disparities and patient safety

The number of racial/ethnic minority children will exceed the number of non-Latino white children in the United States by 2030, but little is known about racial/ethnic disparities in patient safety, particularly when it comes to children. A literature review revealed several racial/ethnic disparities in pediatric patient safety. A new conceptual model is proposed for understanding racial/ethnic disparities in patient safety. Evidence suggests that improving patient safety for minority children could be achieved by routinely collecting and monitoring parental self-reported data on race/ethnicity, language, and English proficiency; enhancing the cultural competency of health care providers and staff; and providing adequate language services for all limited English-proficient patients and their families.

Elective cesarean section and induction and their impact on late preterm births

At all gestational ages, the risks of continuing a pregnancy must be carefully balanced against the risks of delivery and the associates risk of prematurity. This concept is of increasing importance in late preterm pregnancy when medical or obstetric complications frequently warrant delivery and the risk of prematurity persists. Given that morbidity exists for infants born between 34 and 37 weeks gestations, efforts should be focused on minimizing the late preterm birth rate and at improving the outcome of these infants. Published guidelines outlining the appropriate timing of elective induction of labor and elective Cesarean section should be closely followed to avoid unintended iatrogenic prematurity. Research should continue to investigate the etiology of spontaneous preterm deliveries and aim to develop strategies of primary prevention. The incidence and etiology of iatrogenic late preterm birth should also be further investigated and alternative management strategies should be considered. To gain information about the impact of elective delivery on late preterm births, the data collected from birth records should reflect the changing obstetric practices in the United States and be revised to include specific information on elective deliveries.

The child with cerebral palsy: diagnosis and beyond

Cerebral palsy (CP) is one of the most common conditions we follow in our pediatric neurology offices. This review will hopefully convince you that the care of children with CP extends far beyond the diagnosis. The review addresses issues surrounding diagnosis, coimpairments, prognosis, and family-centeredness of care. It will also deal with routine office follow-up to prevent or identify complications, management of spasticity and other morbidities, alternative and complementary therapies, and finally transition.

The Team Approach to Pregnancy and Congenital Heart Disease

The successful pediatric management of congenital heart disease has resulted in increasing numbers of these patients in the reproductive age group and increasing clinical challenges for their physicians. These challenges can be met successfully, with improved results for mother and child, through a concerted comprehensive team approach that relies on a thorough understanding of the patient's underlying cardiac pathology and its anticipated interaction with the pregnancy, and ongoing close evaluation and communication with a team of trained and experienced specialist, including (but not limited to) cardiologist, obstetricians, anesthetists, pediatricians, clinical nurse specialists, and clinical geneticists. Such teams are not always available locally and it will be necessary to refer medium- and high-risk patients to a specialized tertiary care center.

In utero exposure to smoking and newborn neurobehavior: how to assess neonatal withdrawal syndrome?

Recent studies postulate neurotoxic effects of prenatal tabacco exposure, passive addiction, and neonatal nicotine withdrawal syndrome in newborns in utero exposed to maternal smoking. The neonatal withdrawal syndrome is characterized by irritability, tremors, and sleep disturbances, most typically observed in newborns of heavy smoking mothers.

Survey of California Emergency Departments About Practices for Management of Suicidal Patients and Resources Available for Their Care

STUDY OBJECTIVE

To determine the resources available and current practices for the treatment of patients with suicidal ideation or attempts in California emergency departments (EDs).

METHODS

We conducted a mail and e-mail survey of the directors of all 346 EDs in the state of California. Data collected included identification of hospital and respondent, type of hospital, presence of separate psychiatric ED, total number of ED patients and number of ED patients with suicidal ideation or attempts who were treated per week, mental health personnel on call to evaluate suicidal patients, criteria for patient disposition, available disposition options, delays in patient care, changes desired in the ED treatment of suicidal patients, and adequacy of community resources for suicidal patients.

RESULTS

Two hundred twenty-three of 346 (64.5%) ED directors responded to the survey. Overall, the mean estimate of the proportion of ED visits by suicidal patients was 1.7%. Though evaluation of patients with suicidal ideation by a mental health professional was the usual practice, 51 respondents (23%) reported that they occasionally send patients with suicidal ideation home without such an evaluation, and 8.5% reported this was done more than 10% of the time. No single type of mental health professional, including psychiatrist, social worker, county or private psychiatric evaluation team, psychiatric nurse, or psychologist, was available for evaluation of suicidal patients in more than 50% of respondent EDs. In the majority of EDs, psychiatric evaluations were performed by either mobile county or private psychiatric evaluation teams or social workers on call to the ED. Psychiatrists were reported to evaluate the majority of suicidal patients in only 10% of EDs. Only 27% of respondents had the ability to admit patients to a psychiatric service at their hospital. When patients needed to be transferred, the estimated mean wait for these transfers was 7 hours. Seventy-one percent of respondents reported needing improved access to mental health personnel for evaluation of suicidal patients; 61% reported needing improved access to mental health personnel for patient disposition.

CONCLUSION

In California EDs, there are limited mental health services for suicidal patients. Regional solutions to emergency and nonemergency mental health problems are needed, including improved access to mental health personnel for ED evaluation, disposition, and follow-up of suicidal patients and community mental health resources for patient referrals.

Are children of moderately low birth weight at increased risk for poor health? A new look at an old question

OBJECTIVE

The goal was to examine whether moderately low birth weight children were at greater risk for health problems than normal birth weight children in a nationally representative sample of US children.

METHODS

Data were analyzed for 7817 children, 0 to 12 years of age, from the sample child file of the 2002 National Health Interview Survey. Logistic regressions were estimated to examine whether morbidity rates were higher among moderately low birth weight children than among normal birth weight children and to control for covariates. Health was measured as having a special health care need, having a chronic condition, being hospitalized in the past year, having a learning disability, attention-deficit disorder/attention-deficit/hyperactivity disorder, or other behavioral disorders, having minor health conditions, and having acute illnesses.

RESULTS

With control for other confounders, moderately low birth weight children were significantly more likely than normal birth weight children to be identified as having a special health care need, having a chronic condition, having a learning disability, and having attention-deficit disorder or attention-deficit/hyperactivity disorder. They were not more likely to have a hospitalization in the past year, other behavioral disorders, or minor health conditions or acute illnesses.

CONCLUSIONS

This population-based study of rates of current morbidity shows that moderately low birth weight children born since 1990 are vulnerable to a wide range of health, learning, and behavioral problems, compared with normal birth weight children. This suggests the need for continued focus on ways to reduce morbidity rates for moderately low birth weight children.
