RESUMO

Vascular compression syndromes are a group of conditions resulting from mechanical compression of blood vessels by adjacent structures leading to compromised blood flow and various associated symptoms. They frequently affect young, otherwise healthy individuals and are often underdiagnosed due to their rarity and vague clinical manifestations. Achieving an accurate diagnosis depends on the integration of clinical presentation and imaging findings. Imaging modalities including color doppler ultrasound, computed tomography angiography, magnetic resonance angiography, and catheter-directed digital subtraction angiography are essential for diagnosis and management. Dynamic imaging is crucial in eliciting findings due to the positional nature of many of these syndromes. In this paper, we will present a "head-to-toe" overview of vascular compression syndromes including Vascular Eagle Syndrome, Vascular Thoracic Outlet Syndrome, Quadrilateral Space Syndrome, Hypothenar Hammer Syndrome, Median Arcuate Ligament Syndrome, Renal Artery Entrapment Syndrome, Left Renal Vein Compression/Nutcracker Syndrome, May-Thurner Syndrome, Adductor Canal Syndrome, and Popliteal Artery Entrapment Syndrome. Treatment is variable but typically involves a combination of conservative and surgical management. Surgical approaches focus on decompression of affected neurovascular structures. Endovascular treatment alone is rarely recommended. We aim to equip general radiologists with the knowledge needed to accurately diagnose patients with vascular compression syndromes, allowing for timely treatment.

RESUMO

BACKGROUND: Hypertensive disorders of pregnancy are among the leading causes of maternal mortality and morbidity in the U.S., with rates highest among birthing people who are Black, rural residents, and/or have low-income. Severe hypertension, in particular, increases risk of stroke and other serious pregnancy complications. To promote early detection and treatment of severe hypertension, the Alliance for Innovation on Maternal Health developed the Severe Hypertension During Pregnancy and Postpartum Period Safety Bundle (HTN Bundle). Multiple studies have demonstrated the HTN Bundle's effectiveness in the inpatient setting. With funding from the National Heart, Lung, and Blood Institute, we engaged community partners to adapt the HTN Bundle for the outpatient setting (i.e., O-HTN Bundle) and planned for its implementation. In this paper, we describe the protocol for a study evaluating O-HTN Bundle implementation in 20 outpatient clinics serving Black, rural, and/or low-income populations. METHODS: This study is a hybrid type 3 effectiveness-implementation trial with a multiple baseline design. We will implement the O-HTN Bundle in three successive cohorts of clinics using a multicomponent implementation strategy to engage community partners (coalition, patient workgroup) and support clinics (training, facilitation, education materials, and simulations of severe hypertension events). To test the strategy, we will compare clinic fidelity to evidence-based guidelines for (a) patient education on hypertension and (b) blood pressure measurement technique, with repeated measures occurring before and after strategy receipt. We will also observe strategy effects on community- and clinic-level intermediate outcomes (community engagement, organizational readiness), implementation outcomes (reach, adoption, fidelity, maintenance), and effectiveness outcomes (receipt of guideline concordant care). Analyses will address whether outcomes are equitable across Black, rural, and/or low-income subgroups. Guided by the Consolidated Framework for Implementation Research 2.0, we will use mixed methods to identify adaptations and other determinants of implementation success. DISCUSSION: This study integrates community engagement and implementation science to promote equitable and timely response to severe HTN in the outpatient setting during pregnancy and postpartum. This is one of the first studies to implement an outpatient HTN Bundle and to use simulation as a strategy to reinforce team-based delivery of guideline concordant care. TRIAL REGISTRATION: This study was registered with ClinicalTrials.gov as "Testing Implementation Strategies to Support Clinic Fidelity to an Outpatient Hypertension Bundle (AC3HIEVE)." Registration number NCT06002165, August 21, 2023: https://clinicaltrials.gov/study/NCT06002165 .

RESUMO

OBJECTIVES: Behavior problems are one of the most common reasons for seeking mental health services in pediatric populations. The objectives are to evaluate the effects of the EQUIPE program (Étude Québécoise d'Intervention pour les Parents d'Enfants avec des problèmes de comportement) and to analyze the impact of the severity of behavior problems and of parental characteristics. METHODS: This program was translated from the Community Parent Education Program. The effects of EQUIPE, as compared to a control group, were evaluated by using Child Behavior Checklist and Parent Stress Index questionnaires before (T0) and after the intervention program (T1), and at 6 (T2) and 12months (T3) follow-up visits. RESULTS: In total, 533 participants were enrolled in intervention (n=465) (with "severe" or "mild" subgroups according to CBCL-T score) and a control group (n=68). In the two groups, the results showed a statistically significant decrease in Child Behavior Checklist and Parent Stress Index total scores at T1, T2 and T3, with the exception of Child Behavior Checklist total scores in the control group at T2. In the intervention group Child Behavior Checklist total scores were significantly higher in the "severe"; which was not the case for Parent Stress Index total scores at T2 and T3. DISCUSSION: Socioeconomic characteristics, family details, parental medical history and the age of the children appeared to influence changes in Child Behavior Checklist and Parent Stress Index total scores. CONCLUSION: The EQUIPE program is an effective intervention for reducing behavior problems and parents' stress in a French-Canadian population.

RESUMO

Background: Cardiac disease is a leading cause of severe maternal morbidity (SMM). We sought to estimate the effects of race and rural-urban status on cardiac-specific severe maternal morbidity ("cardiac SMM") in North Carolina. Methods: This retrospective study used the 2019 North Carolina State Inpatient Database (SID). Diagnosis codes were used to identify births, comorbidities, modified World Health Organization (mWHO) cardiac category, and outcomes. Hospital-level data were obtained from publicly available sources and the SID datasets. The primary outcome was a composite of cardiac SMM. Results: Of 106,778 births, 369 had mWHO category I-II disease, and 366 had mWHO category II/III-IV disease. Individuals with cardiac disease had higher rates of cardiac SMM (10.4% versus 0.27% versus 0.13% for mWHO II/III-IV, mWHO I/II, and no disease, respectively). Among patients with mWHO II/III-IV disease, 60.0% of rural residents delivered at hospitals with advanced cardiac capabilities versus 80.8% of urban residents; there were no statistically significant differences in cardiac SMM rates (11.3% versus 10.1% for rural versus urban individuals, P = NS). In contrast, there were pronounced disparities in cardiac SMM among Black individuals compared with White individuals (0.28% versus 0.13%, P < .001), especially among individuals with mWHO II/III-IV disease (23.71% versus 5.41%, P < .001). Limitations: Cardiac disease and outcomes were identified based on diagnosis and procedure codes. Identifying complications subsequent to the delivery hospitalization was not possible. Conclusions: In North Carolina, there is a pronounced racial disparity in cardiac SMM during delivery hospitalizations, which is driven by patients with mWHO II/III-IV disease.

RESUMO

BACKGROUND: Preterm birth is a significant clinical and public health issue in the United States. Rates of preterm birth have remained unchanged, and racial disparities persist. Although a causal pathway has not yet been defined, it is likely that a multitude of clinical and social risk factors contribute to a pregnant person's risk. State-based public health and provider programmatic partnerships have the potential to improve care during pregnancy and reduce complications, such as preterm birth. In North Carolina, a state-based Medicaid-managed Pregnancy Medical Home Program screens pregnant individuals for psychosocial and medical risk factors and utilizes community-based care management, to offer support to those at highest risk. OBJECTIVE: This study aimed to examine the association between care-management and birth outcomes (low birthweight and preterm birth rates) among high-risk non-Hispanic White and Black pregnant people enrolled in the North Carolina Pregnancy Medical Home. STUDY DESIGN: This was a quasi-experimental study of people in the Medicaid-managed North Carolina Pregnancy Medical Home who had singleton pregnancies and who enrolled in the program between January 2016 and December 2017. Black and White pregnant people were included in the analysis if they had singleton pregnancies, were enrolled in the Pregnancy Medical Home, and for whom there were data regarding care management involvement. Preterm birth and low birthweight were chosen as the outcomes of interest. Two different methodologies were used to test the effect of care management on outcomes: Method 1 evaluated the effect of intensive care management (≥5 face-to-face visits from a care manager) and Method 2 evaluated the effect of the implementation of a specific risk-stratification system. Chi-squared and multivariate logistic regressions were performed as appropriate. RESULTS: From January 1, 2016 to December 31, 2017, a total of 3564 singleton pregnancies occurred among non-Hispanic Black and White pregnant Medicaid beneficiaries, who were a part of the Pregnancy Medical Home in North Carolina. White pregnant people comprised 57% and Black pregnant people comprised 43% of the sample. In the Method 1 analysis, intensive care management was significantly associated with reductions in preterm birth and low birthweight among Black and White pregnant people whereas in the Method 2 analysis, the implementation of a risk-stratification score only resulted in a significant reduction among Black pregnant people. In multivariable logistic modeling, race, number of prenatal visits, and intensive care management were all significantly associated with the outcomes of interest. CONCLUSION: Care management is associated with reductions in preterm birth and low birthweight in the Medicaid-managed Pregnancy Medical Home in North Carolina. This study contributes to a growing body of literature on the role of state-based initiatives in reducing perinatal morbidity. These results are significant as it demonstrates the importance of care coordination and management, in identifying and providing resources for high-risk pregnant people. In the United States, where pregnancy-related outcomes are poor, programs that address the multitude of economic, social, and clinical complexities are becoming increasingly crucial and necessary.

RESUMO

The number of U.S. births has been declining. There is also concern about rural obstetric units closing. To better understand the relationship between births and obstetric beds during 2000-2019, we examined changes over time in births, birth hospital distributions (i.e., hospital birth volume, ownership, and urban-rural designation), and the ratio of births to obstetric beds. We analyzed American Hospital Association Annual Survey data from 2000 to 2019. We included U.S. hospitals with at least 25 reported births during the year and at least 1 reported obstetric bed. We categorized birth volume to identify and describe hospitals with maternity services using seven categories. We calculated ratios of number of births to number of obstetric beds overall, by annual birth volume category, by three categories of hospital ownership, and by six urban-rural categories. The ratio of births to obstetric beds, which may represent need for maternity services, has stayed relatively consistent at 65 over the past two decades, despite the decline in births and changes in birth hospital distributions. The ratios were smallest in hospitals with < 250 annual births and largest in hospitals with ≥ 7000 annual births. The largest ratios of births to obstetric beds were in large metro areas and the smallest ratios were in noncore areas. At a societal level, the reduction in obstetric beds corresponds with the drop in the U.S. birth rate. However, consistency in the overall ratio can mask important differences that we could not discern, such as the impact of closures on distances to closest maternity care.

RESUMO

BACKGROUND: Rates of maternal mortality and severe maternal morbidity (SMM) are higher in the United States than in other high-resource countries and are increasing further. OBJECTIVE: To examine the association of maternal comorbid conditions, age, body mass index, and previous cesarean birth with occurrence of SMM. DESIGN: Population-based cohort study using linked delivery hospitalization discharge data and vital records. SETTING: California, 1997 to 2014. PATIENTS: All 9 179 472 mothers delivering in California during 1997 to 2014. MEASUREMENTS: SMM rate, total and without transfusion-only cases; 2019 maternal comorbidity index. RESULTS: Total SMM increased by 160% during this time, and SMM excluding transfusion-only cases increased by 53%. Medical comorbid conditions were associated with an increasing portion of SMM occurrences. Medical comorbid conditions increased over the study period by 111%, and obstetric comorbid conditions increased by 30% to 40%. Identified medical comorbid conditions had high relative risks ranging from 1.3 to 14.3 for total SMM and even higher relative risks for nontransfusion SMM (to 32.4). The obstetric comorbidity index that is most often used may be undervaluing the degree of association with SMM. LIMITATIONS: Hospital discharge diagnosis files and birth certificate records can have misclassifications and may not include all relevant clinical data or social determinants. The period for analysis ended in 2014 to avoid the transition to the International Classification of Diseases, 10th Revision, Clinical Modification, and therefore missed more recent years. CONCLUSION: Obstetric and, particularly, medical comorbid conditions are increasing among women who develop SMM. The maternal comorbidity index is a promising tool for patient risk assessment and case-mix adjustment, but refinement of factor weights may be indicated.

RESUMO

OBJECTIVES: Some patients in child and adolescent psychiatry present resistance to psychotropic drugs, often resulting in polytherapy, an increased risk of adverse events, and more frequent and longer hospitalisation. Psychotropic drugs are mainly metabolised in the liver, in particular by the CYP2D6 subunit of cytochrome P450. Anomalies such as a duplication of the CYP2D6 gene related to an ultra-rapid metaboliser phenotype has been described to be linked to clinical efficacy. However, little research has been done in child and adolescent psychiatry. METHODS: A multi-centric cross-sectional study in the southeast of France explored the relation between pharmaco-resistance to psychotropic drugs and the prevalence of duplications or polymorphisms of CYP2D6 associated with an ultra-rapid phenotype in children and adolescents with severe mental health disease. RESULTS: Twenty-two patients have been included. The presence of an ultra-rapid phenotype concerns one patient in our study. A second patient presents a slow metaboliser phenotype. CONCLUSIONS: This study allows a clinical characterisation of the population of pediatric drug-resistant patients whose severity and the impact of their pathology are major and require long-term care associated with repeated hospitalisations, multiple drug prescriptions and numerous side effects. However, a link between drug resistance to psychotropic drugs and CYP2D6 UFM abnormalities could not be confirmed. An additional pharmacogenetic analysis by a panel of genes applied in the metabolism, transport and action of psychotropic drugs should be considered to answer questions about the resistance and independent effects of CYP2D6.

RESUMO

OBJECTIVES: To compare receipt of contraception and method effectiveness in the early postpartum period among women with and without a recent preterm birth (PTB). METHODS: We used data from North Carolina birth certificates linked to Medicaid claims. We assessed contraceptive claims with dates of service within 90 days of delivery among a retrospective cohort of women who had a live birth covered by Medicaid between September 2011 and 2012 (n = 58,201). To estimate the odds of receipt of contraception by PTB status (24-36 weeks compared to 37-42 weeks [referent]), we used logistic regression and tested for interaction by parity. To estimate the relationship between PTB and method effectiveness based on the Center for Disease Control and Prevention Levels of Effectiveness of Family Planning Methods (most, moderate and least effective [referent]), we used multinomial logistic regression. RESULTS: Less than half of all women with a live birth covered by Medicaid in North Carolina had a contraceptive claim within 90 days postpartum. Women with a recent PTB had a lower prevalence of contraceptive receipt compared to women with a term birth (45.7% vs. 49.6%). Women who experienced a PTB had a lower odds of receiving contraception. When we stratified by parity, women with a PTB had a lower odds of contraceptive receipt among women with more than two births (0.79, 95% CI 0.74-0.85), but not among women with two births or fewer. One-fourth of women received a most effective method. Women with a preterm birth had a lower odds of receiving a most effective method (0.83, 95% CI 0.77-0.88) compared to women with a term birth. CONCLUSIONS FOR PRACTICE: Contraceptive receipt was low among women with a live birth covered by Medicaid in North Carolina. To optimize contraceptive use among women at risk for subsequent preterm birth, family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed. SIGNIFICANCE: Access to free or affordable highly effective contraception is associated with reductions in preterm birth. Self-report data indicate that women with a very preterm birth (PTB) are less likely to use highly or moderately effective contraception postpartum compared to women delivering at later gestational ages. Using Medicaid claims data, we found that less than half of all women with a Medicaid covered delivery in North Carolina in 2011-2012 had a contraceptive claim within 90 days postpartum, and one fourth received a most effective method. Women with a PTB and more than two children were least likely to receive any method. Family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed so that women may access their contraceptive method of choice in the postpartum period.

RESUMO

In working to improve the health of North Carolinians, a critical focus starts with our mothers and infants and their surrounding communities. North Carolina's perinatal outcomes, as evidenced by maternal morbidity and mortality, infant mortality, preterm births, and the larger context of lifelong physical and mental health of our citizens, offer areas for improvement and policy implications. In addition, the unacceptable disparities that remain despite some overall improvement in outcomes warrant full attention. This issue of the NCMJ highlights the state of perinatal health in North Carolina; the importance of a risk-appropriate perinatal system of care; the opportunities for supporting our parents, children, and families; and how we as a state and as a community can come together to improve the safety and experience of giving birth in North Carolina and beyond.

RESUMO

Maternal mortality and severe maternal morbidity, particularly among women of color, have increased in the United States. The leading medical causes of maternal mortality include cardiovascular disease, infection, and common obstetric complications such as hemorrhage and vary by timing relative to the end of pregnancy. Although specific modifications in the clinical management of some of these conditions have been instituted, more can be done to improve the system of care for high-risk women at facility and population levels. The goal of levels of maternal care is to reduce maternal morbidity and mortality, including existing disparities, by encouraging the growth and maturation of systems for the provision of risk-appropriate care specific to maternal health needs. To standardize a complete and integrated system of perinatal regionalization and risk-appropriate maternal care, this classification system establishes levels of maternal care that pertain to basic care (level I), specialty care (level II), subspecialty care (level III), and regional perinatal health care centers (level IV). The determination of the appropriate level of care to be provided by a given facility should be guided by regional and state health care entities, national accreditation and professional organization guidelines, identified regional perinatal health care service needs, and regional resources. State and regional authorities should work together with the multiple institutions within a region, and with the input from their obstetric care providers, to determine the appropriate coordinated system of care and to implement policies that promote and support a regionalized system of care. These relationships enhance the ability of women to give birth safely in their communities while providing support for circumstances when higher level resources are needed. This document is a revision of the original 2015 Levels of Maternal Care Obstetric Care Consensus, which has been revised primarily to clarify terminology and to include more recent data based on published literature and feedback from levels of maternal care implementation.

RESUMO

Objectives To estimate the rate of pregnancy-associated emergency care visits and identify maternal and pregnancy characteristics associated with high utilization of emergency care among pregnant Medicaid recipients in North Carolina. Methods A retrospective cohort study using linked Medicaid hospital claims and birth records of 107,207 pregnant Medicaid recipients who delivered a live-born infant in North Carolina between January 1, 2008 and December 31, 2009. Rates were estimated per 1000 member months of Medicaid coverage. High utilization was defined as ≥ 4 visits. Emergency care visits included encounters in the emergency department or obstetric triage unit during pregnancy that did not result in hospital admission. Results During the study period, 57.5% of pregnant Medicaid recipients sought emergency care at least once during pregnancy. There were 171,909 emergency care visits with an overall rate of 202.3 visits per 1000 member months. Among the subset of pregnant women with Medicaid coverage for the majority of their pregnancy (n = 75,157), 18.1% were high utilizers. High emergency care utilization was associated with young age, black race, lower education, tobacco use, late preterm delivery, multifetal gestation, and having ≥ 1 comorbidity. Threatened labor and abdominal pain were the leading indications for visits. Conclusion Utilization of hospital-based emergency care services was common in this cohort of pregnant Medicaid recipients. Additional research is needed to assess the drivers for accessing care through the emergency department, and to examine differences in pregnancy outcomes and health care costs between high and low utilizers.

RESUMO

As captive rhesus macaques often exhibit hair loss, alopecia was quantified and behavior was recorded before, during, and after fatty acid supplementation in six macaques. Fatty acid treatment was associated with a decrease in alopecia and in self-grooming behavior. Therefore, fatty acids may be a viable treatment for alopecia in some captive primates.

RESUMO

Complications arising from hypertensive disorders of pregnancy are among the leading causes of preventable severe maternal morbidity and mortality. Timely and appropriate treatment has the potential to significantly reduce hypertension-related complications. To assist health care providers in achieving this goal, this patient safety bundle provides guidance to coordinate and standardize the care provided to women with severe hypertension during pregnancy and the postpartum period. This is one of several patient safety bundles developed by multidisciplinary work groups of the National Partnership for Maternal Safety under the guidance of the Council on Patient Safety in Women's Health Care. These safety bundles outline critical clinical practices that should be implemented in every maternity care setting. Similar to other bundles that have been developed and promoted by the Partnership, the hypertension safety bundle is organized into four domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. Although the bundle components may be adapted to meet the resources available in individual facilities, standardization within an institution is strongly encouraged. This commentary provides information to assist with bundle implementation.

RESUMO

We present the design, analysis, and experimental characterization of a novel integrated add-drop filter capable of filtering simultaneously two independent channels that is based on a contra-directional grating assisted coupler with two different periods. The device performance is explained using Fourier analysis and confirmed with numerical simulations using the eigenmode expansion method. The devices were fabricated using electron-beam lithography on a silicon-on-insulator wafer with a 220 nm thick device layer. The Fourier analysis, simulations and experimental results are in agreement and show that the drop port response of the two-period configuration is the superposition of the drop port responses of two single-period gratings. Therefore, the output channels at drop port can be designed independently and can have different bandwidths.

RESUMO

We present the design and characterization of a silicon-on-insulator based bandwidth and wavelength-tunable add-drop filter. The tunability of the device is achieved by independently controlling the central wavelength of two cascaded contra-directional grating assisted couplers. The device was fabricated using e-beam lithography and the tuning is demonstrated using the thermo-optic effect, which was obtained with metal heaters fabricated by a lift-off process. It is experimentally demonstrated that within the wavelength range of 1555 nm to 1573 nm the transmission bandwidth of the device can be tuned from 1.1 nm to 11.7 nm. Moreover, more than 4 nm of central wavelength tuning is demonstrated. The tunability of the central wavelength is limited by the breakdown current of the metal heaters.

RESUMO

BACKGROUND: Although a weekly injection of 17-hydroxyprogestone caproate is recommended for preventing recurrent preterm birth, clinical experience in North Carolina suggested that many eligible patients were not receiving the intervention. OBJECTIVE: Our study sought to assess how well practices delivering at 2 major hospitals were doing in providing access to 17-hydroxyprogesterone caproate treatment for eligible patients. STUDY DESIGN: This retrospective cohort analysis studied all deliveries occurring between January 1, 2012, and December 31, 2013, at 2 large hospitals in North Carolina. Women were included if they had a singleton pregnancy and history of a prior spontaneous preterm birth. We extracted demographic, payer, and medical information on each pregnancy, including whether women had been offered, accepted, and received 17-hydroxyprogesterone caproate. Our outcome of 17-hydroxyprogesterone caproate coverage was defined as documentation of ≥1 injection of the drug. RESULTS: Over the 2-year study period, 1216 women with history of a prior preterm birth delivered at the 2 study hospitals, of which 627 were eligible for 17-hydroxyprogesterone caproate eligible after medical record review. Only 296 of the 627 eligible women (47%; 95% confidence interval, 43-51%) received ≥1 dose of the drug. In multivariable analysis, hospital of delivery, later presentation for prenatal care, fewer prenatal visits, later gestation of prior preterm birth, and having had a term delivery immediately before the index pregnancy were all associated with failed coverage. Among those women who were "covered," the median number of 17-hydroxyprogesterone caproate injections was 9 (interquartile range, 4-15), with 84 of 296 charts (28%) not having complete information on the number of doses. CONCLUSION: Even under our liberal definition of coverage, less than half of eligible women received 17-hydroxyprogesterone caproate in this sample. Low overall use suggests that there is opportunity for improvement. Quality improvement strategies, including population-based measurement of 17-hydroxyprogesterone caproate coverage, are needed to fully implement this evidence-based intervention to decrease preterm birth.

RESUMO

Objectives Our pilot study aimed to build knowledge of the postpartum health needs of mothers with infants in a newborn intensive care unit (NICU). Methods Between May 2008 and December 2009, a Certified Nurse Midwife was available during workday hours to provide health care services to mothers visiting their infants in the NICU at a large tertiary care center. Results A total of 424 health service encounters were recorded. Maternal requests for services covered a wide variety of needs, with primary care being the most common. Key health concerns included blood pressure monitoring, colds, coughs, sore throats, insomnia and migraines. Mothers also expressed a need for mental health assessment and support, obstetric care, treatment for sexually transmitted infections, tobacco cessation, breastfeeding assistance, postpartum visits, and provision of contraception. Conclusions Our study suggests that mothers with babies in the NICU have a host of health needs. We also found that women were receptive to receiving health services in a critical care pediatric setting. Intensive care nurseries could feasibly partner with in-patient mother-baby units and/or on-site obstetric clinics to increase access to health care for the mothers of the high-risk newborns in their units. Modifications should be made within health care systems that serve high-risk infants to better address the many needs of the mother/baby dyad in the postpartum period.

RESUMO

In the 1970s, studies demonstrated that timely access to risk-appropriate neonatal and obstetric care could reduce perinatal mortality. Since the publication of the Toward Improving the Outcome of Pregnancy report, more than 3 decades ago, the conceptual framework of regionalization of care of the woman and the newborn has been gradually separated with recent focus almost entirely on the newborn. In this current document, maternal care refers to all aspects of antepartum, intrapartum, and postpartum care of the pregnant woman. The proposed classification system for levels of maternal care pertains to birth centers, basic care (level I), specialty care (level II), subspecialty care (level III), and regional perinatal health care centers (level IV). The goal of regionalized maternal care is for pregnant women at high risk to receive care in facilities that are prepared to provide the required level of specialized care, thereby reducing maternal morbidity and mortality in the United States.

RESUMO

OBJECTIVE: To determine which combination of risk factors from Community Care of North Carolina's (CCNC) Pregnancy Medical Home (PMH) risk screening form was most predictive of preterm birth (PTB) by parity and race/ethnicity. METHODS: This retrospective cohort included pregnant Medicaid patients screened by the PMH program before 24 weeks gestation who delivered a live birth in North Carolina between September 2011-September 2012 (N = 15,428). Data came from CCNC's Case Management Information System, Medicaid claims, and birth certificates. Logistic regression with backward stepwise elimination was used to arrive at the final models. To internally validate the predictive model, we used bootstrapping techniques. RESULTS: The prevalence of PTB was 11 %. Multifetal gestation, a previous PTB, cervical insufficiency, diabetes, renal disease, and hypertension were the strongest risk factors with odds ratios ranging from 2.34 to 10.78. Non-Hispanic black race, underweight, smoking during pregnancy, asthma, other chronic conditions, nulliparity, and a history of a low birth weight infant or fetal death/second trimester loss were additional predictors in the final predictive model. About half of the risk factors prioritized by the PMH program remained in our final model (ROC = 0.66). The odds of PTB associated with food insecurity and obesity differed by parity. The influence of unsafe or unstable housing and short interpregnancy interval on PTB differed by race/ethnicity. CONCLUSIONS: Evaluation of the PMH risk screen provides insight to ensure women at highest risk are prioritized for care management. Using multiple data sources, salient risk factors for PTB were identified, allowing for better-targeted approaches for PTB prevention.
