Despite significant improvements in outcomes following non-obstetric surgery with implementation of enhanced recovery after surgery (ERAS) protocols, development of these protocols for cesarean delivery is lacking. We evaluated implementation of an ERAS protocol for patients undergoing elective cesarean delivery, specifically the effect on opioid consumption, pain scores and length of stay as well as complications and re-admissions.An ERAS protocol was developed and implemented for women undergoing elective cesarean delivery. The protocol construction included specific evidence-based items applicable to peripartum management and these were grouped into the three major phases of patient care: antepartum, intrapartum and postpartum. A before-and-after study design was used to compare maternal outcomes. To account for confounders between groups, a propensity matched scoring analysis was used. The primary outcome was postpartum opioid use in mg-morphine equivalents (MMEQ).We included 357 (n=196 before; n=161 after) women who underwent elective cesarean delivery. A significant difference in opioid consumption (28.4 ± 24.1 vs 46.1 ± 37.0 MMEQ, P 0.001) and in per-day postoperative opioid consumption (10.9 ± 8.7 vs 15.1 ± 10.3 MMEQ, P 0.001), lower peak pain scores (7 [5-9] vs 8 [7-9], P=0.007) and a shorter hospital length of stay (2.5 ± 0.5 vs 2.9 ± 1.2 days, P 0.001) were found after the introduction of the ERAS protocol.Implementation of ERAS protocols for elective cesarean delivery is associated with significant improvements in analgesic and recovery outcomes. These improvements in quality of care suggest ERAS protocols should be considered for elective cesarean delivery.

Enhanced recovery after cesarean delivery (ERAC) programs aim to decrease maternal morbidity and aid in maternal recovery and return to baseline. Multimodal analgesia is an important element of ERAC protocols, but no consensus exists on the timing of medication administration. We compared maternal pain outcomes following scheduled cesarean delivery with modification of the timing of administration of multimodal analgesia with non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen.Before-and-after study.Labor and delivery unit at a single academic institution.NSAIDs and acetaminophen were administered as a fixed-interval alternating regimen every 3 h for the initial ERAC group (ERAC 1) and fixed-interval combined regimen every 6 h for the modified ERAC group (ERAC 2). ERAC 1 and ERAC 2 groups were compared to historical controls (Pre-ERAC).520 women undergoing scheduled cesarean delivery (Pre-ERAC n = 179, ERAC 1 n = 179, and ERAC 2 n = 162).The primary outcomes were postoperative total and daily opioid utilization as measured in morphine milligram equivalents (MME). Secondary outcomes included postoperative length of stay, maximum pain scores, and racial disparities in care.The modified schedule of non-opioid analgesics involving combined administration (ERAC 2) versus alternating administration (ERAC 1) of multimodal analgesia resulted in decreased total postoperative opioid utilization (median = 26.3 vs 52.5 MME, Bonferroni corrected P = 0.002). Total postoperative opioid utilization among the ERAC 2 group was also significantly reduced compared to the Pre-ERAC group (median = 26.3 vs 105.0 MME, Bonferroni corrected P 0.0001).Multidisciplinary teams developing or modifying ERAC protocols for scheduled cesarean delivery should consider a combined administration at fixed intervals of NSAIDs and acetaminophen throughout the hospital stay to optimize postoperative pain management.

ObjectiveThe number of women aged 45 and older who become pregnant is increasing. The objective of this study was to estimate the risk of medical and obstetric complications among women aged 45 and older.MethodsThe Nationwide Inpatient Sample was used to identify pregnant woman during admission for delivery. Deliveries were identified using International Classification of Diseases, Ninth Revision (ICD-9-CM) codes. Using ICD-9-CM codes, pre-existing medical conditions and medical and obstetric complications were identified in women at the time of delivery and were compared for women aged 45 years and older to women under age 35. Outcomes among women aged 35-44 were also compared to women under age 35 to determine if women in this group demonstrated intermediate risk between the older and younger groups. Logistic regression analyses were used to calculate odds ratios with 95% confidence intervals for pre-existing medical conditions and medical and obstetric complications for both older groups relative to women under 35. Multivariable logistic regression analyses were also developed for outcomes at delivery among older women, while controlling for pre-existing medical conditions, multiple gestation, and insurance status, to determine the effect of age on the studied outcomes.ResultsWomen aged 45 and older had higher adjusted odds for death, transfusion, myocardial infarction/ischemia, cardiac arrest, acute heart failure, pulmonary embolism, deep vein thrombosis, acute renal failure, cesarean delivery, gestational diabetes, fetal demise, fetal chromosomal anomaly, and placenta previa compared to women under 35.ConclusionPregnant women aged 45 and older experience significantly more medical and obstetric complications and are more likely to die at the time of a delivery than women under age 35, though the absolute risks are low and these events are rare. Further research is needed to determine what associated factors among pregnant women aged 45 and older may contribute to these findings.

OBJECTIVES To evaluate the concordance between second-trimester anatomic ultrasound and fetal echocardiography in detecting minor and critical congenital heart disease in pregnancies meeting American Heart Association criteria. METHODS We conducted a retrospective cohort study of pregnancies in which a second-trimester fetal anatomic ultrasound examination (18-26 weeks) and fetal echocardiography were performed between 2012 and 2018 at our institution based on American Heart Association recommendations. Anatomic ultrasound studies were interpreted by maternal-fetal medicine specialists and fetal echocardiographic studies by pediatric cardiologists. Our primary outcome was the proportion of critical congenital heart disease (CCHD) cases not detected by anatomic ultrasound but detected by fetal echocardiography. The secondary outcome was the proportion of total congenital heart disease cases missed by anatomic ultrasound but detected by fetal echocardiography. Neonatal medical records were reviewed for all pregnancies when obtained and available. RESULTS Overall, 722 studies met inclusion criteria. Anatomic ultrasound and fetal echocardiography were in agreement in detecting cardiac abnormalities in 681(96.1%) studies (κ = 0.803; P

Intimate partner violence is a significant public health problem in our society, affecting women disproportionately. Intimate partner violence takes many forms, including physical violence, sexual violence, stalking, and psychological aggression. While the scope of intimate partner violence is not fully documented, nearly 40% of women in the United States are victims of sexual violence in their lifetimes and 20% are victims of physical intimate partner violence. Other forms of intimate partner violence are likely particularly underreported. Intimate partner violence has a substantial impact on a woman's physical and mental health. Physical disorders include the direct consequences of injuries sustained after physical violence, such as fractures, lacerations and head trauma, sexually transmitted infections and unintended pregnancies as a consequence of sexual violence, and various pain disorders. Mental health impacts include an increased risk of depression, anxiety, posttraumatic stress disorder, and suicide. These adverse health effects are amplified in pregnancy, with an increased risk of pregnancy outcomes such as preterm birth, low birthweight, and small for gestational age. In many US localities, suicide and homicide are leading causes of pregnancy-associated mortality. We herein review the issues noted previously in greater depth and introduce the basic principles of intimate partner violence prevention. We separately address current recommendations for intimate partner violence screening and the evidence surrounding effectiveness of intimate partner violence interventions.

In the first part of this review, we provided currently accepted definitions of categories and subcategories of intimate partner violence and discussed the prevalence and health impacts of intimate partner violence in nonpregnant and pregnant women. Herein we review current recommendations for intimate partner violence screening and the evidence surrounding the effectiveness of intimate partner violence interventions. Screening for intimate partner violence may include exclusively identification of victims of intimate partner violence or both the identification of and intervention for victims. Until recently, many professional organizations did not recommend universal screening for intimate partner violence because of a lack of evidence of effectiveness of screening, lack of evidence demonstrating that screening is not harmful, and/or a lack of consensus regarding the most effective screening tool. The lack of evidence supporting an intervention posed an additional barrier to screening. The American College of Obstetricians and Gynecologists has been a staunch advocate for universal intimate partner violence screening, even when other groups either did not endorse screening or recommended it only for high-risk women. Recent published data confirm that screening is more reliable than usual care in identifying victims of intimate partner violence, both during pregnancy and in nonpregnant women. Likewise, recent published data show that there are no apparent harms of screening for intimate partner violence and that the act of screening may have an empowering effect on women and improve their relationship with and trust in their health care providers. Despite these findings, the implementation rate of intimate partner violence screening remains low. Most encouraging are the recent data showing that interventions performed after screening for intimate partner violence are effective in reducing depression symptoms and episodes of violence as well as improving some outcomes of pregnancy. Although there remains a lack of consensus regarding which screening tool may be the most effective, we exhort all obstetrician-gynecologists to screen all women for intimate partner violence at regular intervals and to familiarize themselves with available community resources to assist those women who have been identified as experiencing intimate partner violence through screening.

Gestational primary hyperparathyroidism (GPHPT) is a rare condition with fewer than 200 cases reported. We present the case of a 21-year-old woman who presented at 10 weeks’ gestation with severe hypercalcemia. Laboratory investigation was consistent with primary hyperparathyroidism. Neck ultrasound did not reveal any parathyroid enlargement. Due to the persistence of severe hypercalcemia, she was treated with 4 weeks of cinacalcet therapy, which was poorly tolerated due to nausea and vomiting. At 14 weeks’ gestation, she underwent neck exploration with right lower, left upper, and partial right upper parathyroid gland excision. Intra- and postoperative parathyroid hormone (PTH) and calcium levels remained elevated. After a thorough discussion of risks/benefits, the patient requested further treatment. A parathyroid sestamibi scan (PSS) revealed an ectopic adenoma in the left mediastinum. The adenoma was removed via video-assisted thorascopic parathyroidectomy with intraoperative PTH declining to nearly undetectable levels. She ultimately delivered a physically and developmentally normal infant at 37 weeks’ gestation. Appropriate treatment of severe GPHPT may prevent the maternal and fetal complications of hypercalcemia. This case, in which cinacalcet therapy and PSS were used, adds to the body of literature regarding treatment of severe GPHPT., We present a case of gestational primary hyperparathyroidism due to ectopic parathyroid adenoma that was successfully diagnosed and treated with parathyroid sestamibi scan, cinacalcet, and surgery.

To estimate whether performance of salpingectomy compared with standard tubal ligation for sterilization at the time of cesarean delivery increases operating time or complication rates.A randomized controlled noninferiority trial was performed at a single academic institution. Women undergoing planned cesarean delivery who desired sterilization were randomized to salpingectomy or standard tubal ligation. The primary outcome was length of time of the sterilization procedure, with the noninferiority margin set at 5 minutes. With a one-sided independent sample t test, to achieve a power of 90% with an α of 0.05, 18 women needed to complete each intervention.Forty-four women were enrolled, with 19 successfully undergoing salpingectomy and 18 undergoing standard tubal ligation. Salpingectomy could not be completed in 1 of 20 patients (as a result of adhesions). Baseline demographics were equivalent between groups. Salpingectomy procedure time was noninferior to standard tubal ligation, with a mean difference of 0.5 minutes, with a mean sterilization procedure time of 5.6 minutes in the salpingectomy group and 6.1 minutes in the standard tubal ligation group (P.05, one-sided 95% CI upper bound 1.8 minutes). There was no difference between cesarean delivery with salpingectomy compared with cesarean delivery with standard tubal ligation in median total operating time (60 vs 68 minutes, P=.34) or estimated blood loss (600 vs 700 mL, P=.09). No patients in either group required reoperation or readmission.Salpingectomy procedure time was not longer than standard tubal ligation during cesarean delivery, with a mean difference of 30 seconds. There was a high completion rate for salpingectomy (95%) and no apparent increase in complications.Clinicaltrials.gov, NCT03028623.

Although women's health settings could provide access to women for screening, brief intervention, and referral to treatment (SBIRT) for risky alcohol use, little is known about rates of alcohol use or associated risk for alcohol-exposed pregnancy (AEP) among women's health patients, receipt of SBIRT services in these settings, or patient attitudes towards SBIRT services.This study reports the results of a self-administered survey to a convenience sample of women's health patients attending public clinics for family planning or sexually transmitted infection visits.Surveys were analyzed for 199 reproductive-aged women who had visited the clinic within the past year. The rate of risky drinking among the sample was (44%) and risk for AEP was (17%). Despite this, many patients did not receive SBIRT services, with more than half of risky drinking patients reporting that they were not advised about safe drinking limits (59%) and similar rates of patients at risk for AEP reporting that their medical provider did not discuss risk factors of AEP (53%). Patient attitudes towards receipt of SBIRT services were favorable; more than 90% of women agreed or strongly agreed that if their drinking was affecting their health, their women's health provider should advise them to cut down.Women's health clinics may be an ideal setting to implement SBIRT and future research should address treatment efficacy in these settings.

Cardiac arrhythmia as a complication of pregnancy can be problematic to maternal health and fetal life and development. Catheter ablation of tachyarrhythmias during pregnancy has been successfully performed in selected patients with limited experience. Techniques to limit maternal and fetal radiation exposure, including intracardiac echo and electroanatomic mapping systems, are particularly important in this setting. Specific accommodations are necessary in the care of the gravid patient during catheter ablation.

Background: Anemia in pregnancy increases the need for blood transfusion during and after delivery and is associated with an increased risk of maternal and fetal mortality, therefore preventing maternal anemia may improve outcomes. Iron deficiency is the most common pathologic cause of anemia in pregnancy and is estimated to affect about 30% of pregnant women in the third trimester in the US. The baseline peripartum blood transfusion rate at our institution is 3.2%. Historically, patients who may have benefited from intravenous (IV) iron were continued on oral iron and subsequently delivered with persistent iron deficiency anemia. If identified to need IV iron, these patients were usually referred to a hematologist. However, in the absence of a structured protocol, referral was provider-dependent. Objective: We formed a multidisciplinary work group consisting of members from the departments of Hematology, Obstetrics, Pharmacy, Nursing, and Blood Bank to reduce peripartum blood transfusions by developing a process to manage pregnant patients with iron deficiency anemia. The treatment algorithm utilized at our institution was adapted from "How I treat anemia in pregnancy: iron, cobalamin, and folate" (Achebe & Gafter-Gvili, 2017), which recommends IV iron for hemoglobin less than 11 g/dL and ferritin less than 30 µg/dL in the third trimester and for hemoglobin less than 10.5 g/dL and ferritin less than 30 µg/dL in the second trimester along with recommendations for iron repletion in the first trimester. The primary endpoint was the utilization of blood transfusion. Secondary endpoints included an increase in maternal hemoglobin after treatment and evaluating the safety of IV ferric carboxymaltose as measured by side effects and frequency of hypophosphatemia. Five months after initiation of the IV iron recommendations, we performed an audit to assess its use. Methods: A retrospective IRB-approved chart review of anemic, iron-deficient pregnant women who received IV ferric carboxymaltose from 1/30/19 - 6/30/19 was performed. Thirty-six patients were identified and their charts were reviewed to determine the hemoglobin and ferritin levels prior to IV iron, the number of IV iron infusions received with any side effects, phosphorus levels on days of IV iron, hemoglobin level after IV iron, and need for peripartum blood transfusion. Results: Of the 36 patients who received IV iron for anemia in pregnancy, post-IV iron hemoglobin and blood transfusion information was only available for 26 patients. The remaining 10 patients had not delivered as yet or had delivered at another institution so data were not available. Of these 26 patients, the median age was 26.0 years and all received IV iron during their third trimester. No patients required a blood transfusion peripartum. The average hemoglobin prior to IV iron was 9.3 g/dL and the average hemoglobin after 1-2 IV iron infusions was 11.3 g/dL, an increase of 2.0 g/dL across the total group (Figure 1) (p Conclusion: Results from the first 5 months of this project suggest using a standardized iron deficiency anemia treatment protocol including IV iron to reduce the need for peripartum blood transfusion and increase hemoglobin levels. Additionally, our data suggest IV ferric carboxymaltose is well-tolerated in these patients. These results also support using multi-professional teams to improve the quality of healthcare delivery to pregnant patients with iron deficiency anemia. We have created an IRB-approved database to study more patient-centered postpartum outcomes such as quality of life among IV iron recipients as well as lactation rates and fetal outcomes. We plan to expand this strategy to other patients who have a predictable and likely preventable need for intermittent blood transfusion, such as patients with chronic gynecologic blood loss.

Background Establishing lung inflation prior to umbilical cord clamping may improve the cardiovascular transition and reduce the risk of intraventricular hemorrhage in preterm infants. We developed a pilot feasibility and safety study in which infants Methods Infants born between 24 0/7 and 32 6/7 weeks' gestation whose mothers consented were enrolled. All infants received continuous positive airway pressure or positive pressure ventilation during 90 seconds of DCC. Outcomes included feasibility (ability to complete protocol and maintain a sterile field during cesarean deliveries) and safety variables (Apgar scores, umbilical cord pH and base deficit, admission temperature, and postcesarean infection). Results A total of 29 infants were enrolled, including one set of twins (median gestation: 30 weeks; 72% cesarean births). In all cases, the protocol was completed. Heart rate at 60 seconds was more than 100 beats per minute in all infants. Apgar scores, cord blood gas values, and admission temperature were comparable to other preterm deliveries at our institution. Conclusion Assisting ventilation of very preterm infants during 90 seconds of DCC is challenging but feasible and appears to be safe in this small pilot study. A randomized clinical trial is warranted to determine clinical benefit.

The number of women aged 45 and older who become pregnant is increasing. The objective of this study was to estimate the risk of medical and obstetric complications among women aged 45 and older.The Nationwide Inpatient Sample was used to identify pregnant woman during admission for delivery. Deliveries were identified using International Classification of Diseases, Ninth Revision (ICD-9-CM) codes. Using ICD-9-CM codes, pre-existing medical conditions and medical and obstetric complications were identified in women at the time of delivery and were compared for women aged 45 years and older to women under age 35. Outcomes among women aged 35-44 were also compared to women under age 35 to determine if women in this group demonstrated intermediate risk between the older and younger groups. Logistic regression analyses were used to calculate odds ratios with 95% confidence intervals for pre-existing medical conditions and medical and obstetric complications for both older groups relative to women under 35. Multivariable logistic regression analyses were also developed for outcomes at delivery among older women, while controlling for pre-existing medical conditions, multiple gestation, and insurance status, to determine the effect of age on the studied outcomes.Women aged 45 and older had higher adjusted odds for death, transfusion, myocardial infarction/ischemia, cardiac arrest, acute heart failure, pulmonary embolism, deep vein thrombosis, acute renal failure, cesarean delivery, gestational diabetes, fetal demise, fetal chromosomal anomaly, and placenta previa compared to women under 35.Pregnant women aged 45 and older experience significantly more medical and obstetric complications and are more likely to die at the time of a delivery than women under age 35, though the absolute risks are low and these events are rare. Further research is needed to determine what associated factors among pregnant women aged 45 and older may contribute to these findings.

This study was designed to compare the neonatal abstinence syndrome (NAS) in neonates of methadone and buprenorphine maintained pregnant opioid-dependent women and to provide preliminary safety and efficacy data for a larger multi-center trial. This randomized, double-blind, double-dummy, flexible dosing, parallel-group controlled trial was conducted in a comprehensive drug-treatment facility that included residential and ambulatory care. Participants were opioid-dependent pregnant women and their neonates. Treatment involved daily administration of either sublingual buprenorphine or oral methadone using flexible dosing of 4-24 mg or 20-100 mg, respectively. Primary a priori outcome measures were: (1) number of neonates treated for NAS; (2) amount of opioid agonist medication used to treat NAS; (3) length of neonatal hospitalization; and (4) peak NAS score. Two of 10 (20%) buprenorphine-exposed and 5 of 11 (45.5%) methadone-exposed neonates were treated for NAS (p=.23). Total amount of opioid-agonist medication administered to treat NAS in methadone-exposed neonates was three times greater than for buprenorphine-exposed neonates (93.1 versus 23.6; p=.13). Length of hospitalization was shorter for buprenorphine-exposed than for methadone-exposed neonates (p=.021). Peak NAS total scores did not significantly differ between groups (p=.25). Results suggest that buprenorphine is not inferior to methadone on outcome measures assessing NAS and maternal and neonatal safety when administered starting in the second trimester of pregnancy.

OBJECTIVE: We sought to test the hypothesis that nulliparous women with multiple gestations would be more likely to have shorter gestational durations, a higher frequency of previable deliveries, and fewer pregnancy complications when compared with parous women. METHODS: We reviewed the medical records of women who delivered a multiple gestation at 15 or more weeks at 2 institutions between January 1, 1990 and June 30, 2002 (n = 1,035). We recorded demographic data, medical complications, and pregnancy outcomes and analyzed these using paired t tests for continuous variables, X 2 for categorical variables, and linear regression analysis for the effect of multiple variables on the primary outcome variable, gestational age at delivery. RESULTS: There was a statistically significant difference in mean gestational age at delivery (34 versus 34.9 weeks, P = .006) between the nulliparous and multiparous groups after excluding women with a history of previous preterm birth and/or midtrimester loss. There were no differences between groups in the likelihood of delivering before 20, 24, or 28 weeks. In linear regression analysis, ongoing fetal number (P

OBJECTIVE: To estimate the utility of fetal echocardiography in the evaluation of the fetus with isolated single umbilical artery. METHODS: A retrospective analysis of fetuses diagnosed with single umbilical artery by sonography was conducted between January 1995 and June 2000 (n = 127). In the 103 patients who had fetal echocardiograms, we examined the frequency of abnormal echocardiographic findings when the initial sonogram demonstrated a normal four-chamber view and cardiac outflow tracts. RESULTS: Approximately 1% of fetal anomaly screens had a diagnosis of single umbilical artery. Of these, 72% were isolated (no other anomalies identified). No fetus in this group had an abnormal echocardiogram. There was one postnatal diagnosis of cardiac disease in this group; it was not predicted by either the four-chamber and outflow tract views or the echocardiogram. Among the group with other anomalies, the four-chamber view predicted every abnormal echocardiogram but one. CONCLUSION: Fetal echocardiography does not appear to add further diagnostic information to the antenatal evaluation of the fetus with isolated single umbilical artery when normal four-chamber and outflow tract views of the heart have already been obtained.

Cardiac arrhythmia as a complication of pregnancy can be problematic to maternal health and fetal life and development. Catheter ablation of tachyarrhythmias during pregnancy has been successfully performed in selected patients with limited experience. Techniques to limit maternal and fetal radiation exposure, including intracardiac echo and electroanatomic mapping systems, are particularly important in this setting. Specific accommodations are necessary in the care of the gravid patient during catheter ablation.

Twin gestations comprise approximately 1 percent of all pregnancies (1), and are associated with increased perinatal morbidity and mortality, mainly due to the increased incidence of prematurity and growth restriction (2). Hazards of twin delivery can be attributed to malpresentation, most often by the second twin. The vertex-nonvertex presentation occurs in approximately 40 percent of all twins (3, 4). Although there is consensus regarding the safety of vaginal delivery for twins when both are vertex (5), controversy exists over intrapartum management when the second twin is nonvertex. Some investigators advocate cesarean delivery, particularly when the second twin is nonvertex (6), or if the expected birth weight is < 2000 gm (6-8). This review aims to determine whether vaginal delivery of the nonvertex second twin, either by breech extraction or attempted external cephalic version, is associated with increased morbidity or mortality over cesarean delivery.

An aneurysm of the vein of Galen is a rare arteriovenous malformation of the central nervous system. Fetal manifestations have included nonimmune hydrops, hydrocephalus, and intracranial hemorrhage. This anomaly may be diagnosed prenatally by several imaging modalities. A cystic cranial mass was identified by ultrasound in a fetus at 30 weeks gestation. Both pulsed-wave Doppler and color-velocity imaging studies suggested aneurysm of the vein of Galen was the most likely diagnosis. The fetus demonstrated no evidence of hydrops on serial ultrasound examinations. A 2430 g female infant was delivered vaginally at 35 weeks gestation. Postnatal management included transarterial embolization of the vessels feeding the aneurysm with craniectomy, an intra-aneurysmal balloon, and vascular microcoils. Hydrocephalus developed and a ventriculo-peritoneal shunt was placed. The infant has grown appropriately in the first year of life. An aneurysm of the vein of Galen may be diagnosed prenatally by real-time ultrasound, pulsed-wave Doppler, color-velocity imaging, or magnetic resonance imaging. The presence of this malformation should prompt close follow-up for the remainder of the pregnancy. Careful obstetric management and early postnatal intervention may lead to a favorable outcome.

Poster Presentation Purpose for the Program The specific intent was to assess the effect of a telemedicine‐based high‐risk prenatal clinic on maternal‐child health outcomes for low‐income women in rural communities. Proposed Change Adequate and early access to risk‐appropriate prenatal care can reduce the incidence of adverse outcomes. Limited access disproportionately affects women of low socioeconomic status and with limited English proficiency in rural communities. Distance and costs associated with frequent travel and the limited number of perinatologists are barriers to high‐risk care. Telemedicine can reduce barriers through collaboration of perinatologists and advanced practice nurses. Telemedicine has shown favorable results in a variety of clinical disciplines. Prenatal care is a relative newcomer to the spectrum of health care provided via telemedicine. Implementation, Outcomes, and Evaluation Collaborative high‐risk obstetric (OB) telemedicine clinics were implemented in five rural locations between 2009 and 2013. Local clinics serving the targeted population were solicited as partners. Hands‐on prenatal care and examinations at the local site were provided by nurse practitioners. Video telemedicine visits were in real time with the patient, local practitioner, and remote perinatologist. The telemedicine clinics served 374 patients. With Institutional Review Board (IRB) approval, charts were reviewed to compare patient access measures and pregnancy outcomes before and after initiation of telemedicine. The comparison group consisted of 181 patients. Demographic, patient access, and pregnancy outcome data for women referred before and after the initiation of the telemedicine clinics were compared using two‐sample t test and chi‐square test. Women who received care before telemedicine had a higher rate of missing one or more prenatal visits compared with the telemedicine group (57.1% vs. 21.3%, p = .000). The overall missed visit rate decreased from 0.71% to 0.53% per patient ( p = .086). There was no difference in the groups for gestational age at first visit (13.6 vs. 14.0 weeks of gestation). Deliveries after 37 weeks of gestation were similar (84% pretelemedicine vs. 83% telemedicine). The telemedicine group had a higher mean birth weight (3,226 vs. 3,137 g, p = not significant). There was no difference in the neonatal intensive care unit (NICU) admission rate (12.0% vs. 10.8%); mean NICU days were reduced in the telemedicine group (22.11–13.42, p Implications for Nursing Practice Collaborative care through telemedicine is an effective method for providing high‐risk prenatal care to women who live in rural communities. When compared with traditional care, telemedicine is associated with improved access to care and similar rates of important outcomes.
