Racial and Ethnic Disparities in Delivery In-Hospital Mortality or Maternal End-Organ Injury: A Multistate Analysis, 2007-2020.

Background: In the United States, Black maternal mortality is 2-4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. Materials and Methods: We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020. Multilevel multivariable models were used to test the confounder-adjusted association for race/ethnicity and the binary outcomes (1) in-hospital mortality or maternal end-organ injury and (2) in-hospital mortality only. Stratified analyses were performed to test effect modification. Results: The confounder-adjusted odds ratio showed that Black (1.33, 95% confidence interval [CI]: 1.30-1.36) and Hispanic (1.14, 95% CI: 1.11-1.18) as compared with White patients were more likely to die in-hospital or experience maternal end-organ injury. For Black and Hispanic patients, stratified analysis showed that findings remained significant in almost all homogeneous strata. After statistical adjustment, Black as compared with White patients were more likely to die in-hospital (1.49, 95% CI: 1.21-1.82). Conclusions: Black and Hispanic patients had higher adjusted odds of in-patient mortality and end-organ damage after birth than White patients. Race and ethnicity serve as strong predictors of health care inequality, and differences in outcomes may reflect broader structural racism and individual implicit bias. Proposed solutions require immense and multifaceted active efforts to restructure how obstetrical care is provided on the societal, hospital, and patient level.

Patient- and Hospital- Level Disparities in Severe Maternal Morbidity: a Retrospective Multistate Analysis, 2015-2020.

The rate of severe maternal morbidity (SMM) in the United States (US) rose roughly 9% among all insured racial/ethnic groups between 2018 and 2020, disproportionately affecting racial and ethnic minority populations. Limited research on hospital-level factors and SMM found that even after adjusting for patient-level factors, women of all races delivering in high Black-serving delivery units had higher odds of SMM. Our retrospective cohort study augments the current understanding of multi-level racial/ethnic disparities in SMM by analyzing patient- and hospital- level factors using multistate data from 2015 to 2020. Because rises in SMM have been driven in part by an increase in blood transfusions, multivariable logistic regression models were employed to estimate the impact of patient- and hospital-level factors on the adjusted odds of experiencing any SMM, with and without blood transfusions, as well as blood transfusions alone. Our cohort consisted of 3,497,233 deliveries: 56,885 (1.63%) with any SMM, 16,070 (0.46%) with SMM excluding blood transfusion, and 45,468 (1.30%) with blood transfusions alone. We found that Black race, Hispanic ethnicity, and delivering at Black-serving delivery-units, both independently and interactively, increase the odds of any SMM with or without blood transfusions. Our findings illustrate the persistence of structural- and individual- level racial and ethnic disparities in maternal outcomes over time and emphasize the need for multi-level public policies to address racial/ethnic disparities in maternal healthcare.

Enhanced Recovery after Surgery for Cesarean Delivery: A Quality Improvement Initiative.

OBJECTIVE: Enhanced recovery after surgery (ERAS) was developed as a way to standardize clinical care pathways and communication across multidisciplinary teams to improve patient recovery and reduce hospital length of stay (LOS). Our objective was to implement an ERAS protocol for cesarean delivery (ERAS-CD) and evaluate its efficacy in reducing LOS. STUDY DESIGN: An ERAS-CD program was implemented at our institution in October 2018. Patients undergoing scheduled and unscheduled CD were maintained on an ERAS pathway of care, which included preoperative hydration, standardized intraoperative protocols, and postoperative analgesic regimens as well as early feeding, urinary catheter removal, and ambulation. We compared LOS after delivery (calculated from time of delivery to discharge), readmission rates, health care disparities and postoperative opioid prescribing practices before (October 2017-September 2018) and after (November 2018-October 2019) ERAS implementation. We excluded any outliers, defined as a LOS >25 days. Continuous data are expressed as mean ± standard deviation. Student's t-test and Chi-square were used for statistical comparison with p <0.05 considered statistically significant. RESULTS: There were 1,729 patients who had a CD in the pre-ERAS group with a mean LOS after delivery of 3.32 ± 6.19 days. In the post-ERAS group, 1,753 women underwent CD with a mean LOS after delivery of 2.85 ± 5.79 days, a statistically significant difference from the pre-ERAS group (p <0.001). There was no difference in readmission rates between pre- and post-ERAS implementation groups (1.9 vs. 2.2%, p = 0.53). There was a reduction in health care disparities in postoperative LOS, when stratifying by race-ethnicity, and a reduction in opioid prescribing practices after the implementation of the program. CONCLUSION: With the implementation of an ERAS-CD program, we achieved a reduced LOS, without increasing readmission rates, and saw a reduction in health care disparities and opioid dispensing. A shorter LOS could offer an enhanced patient experience, as well as improved and equitable perioperative outcomes. KEY POINTS: · ERAS-CD is associated with a reduction in postoperative hospital length of stay.. · A reduction in health care disparities by race-ethnicity was observed with the implementation of ERAS-CD.. · A reduction in opioid dispensing was observed with the implementation of ERAS-CD..

Disparities in Obstetric Readmissions: A Multistate Analysis, 2007-2014.

OBJECTIVE: Hospital readmissions are generally higher among racial-ethnic minorities and patients of lower socioeconomic status. However, this has not been widely studied in obstetrics. The aim of the study is to determine 30-day postpartum readmission rates by patient-level social determinants of health: race ethnicity, primary insurance payer, and median income, independently and as effect modifiers. STUDY DESIGN: Using state inpatient databases from the health care cost and utilization project from 2007 to 2014, we queried all deliveries. To produce accurate estimates of the effects of parturients' social determinants of health on readmission odds while controlling for confounders, generalized linear mixed models (GLMMs) were used. Additional models were generated with interaction terms to highlight any associations and their effect on the outcome. Adjusted odds ratios (aOR) with 95% confidence intervals are reported. RESULTS: There were 5,129,867 deliveries with 79,260 (1.5%) 30-day readmissions. Of these, 947 (1.2%) were missing race ethnicity. Black and Hispanic patients were more likely to be readmitted within 30 days of delivery, as compared with White patients (p < 0.001 and p < 0.05, respectively). Patients with government insurance were more likely to be readmitted than those with private insurance (p < 0.001). Patients living in the second quartile of median income were also more likely to be readmitted than those living in other quartiles (p < 0.05). Using GLMMs, we observed that Black patients with Medicare were significantly more likely to get readmitted as compared with White patients with private insurance (aOR 2.78, 95% CI 2.50-3.09, p < 0.001). Similarly, Black patients living in the fourth (richest) quartile of median income were more likely to get readmitted, even when compared with White patients living in the first (poorest) quartile of median income (aOR 1.48, 95% CI 1.40-1.57, p < 0.001). CONCLUSION: Significant racial-ethnic disparities in obstetric readmissions were observed, particularly in Black patients with government insurance and even in Black patients living in the richest quartile of median income. KEY POINTS: · Using generalized linear mixed models, we observed significant interactions.. · Government-insured Black patients were 2.78X more likely to be readmitted.. · The wealthiest Black patients were still 1.48X more likely to be readmitted..

Inpatient mortality and postpartum readmission rates in sickle cell disease pregnancies: a multistate analysis, 2007-2014.

OBJECTIVE: We compared post-partum outcomes between sickle cell disease (SCD) and non-sickle cell populations. METHODS: We conducted a retrospective analysis of discharge data for 6,911,916 inpatient deliveries in the states of California, Florida, New York, Maryland, and Kentucky from 2007 to 2014 using data from the State Inpatient Databases, Healthcare Cost and Utilization Project. We compared unadjusted rates and adjusted odds of 30- and 90-d readmission rates, in-hospital mortality, length of stay (LOS), and total hospital charges in SCD, sickle cell trait, and non-sickle cell patients. RESULTS: Compared to non-sickle cell patients, SCD patients were more than two times as likely to die in-hospital (aOR: 2.16, 95% CI: 1.15-4.04, p < .05), 27% as likely to be readmitted up to 30 d postdelivery (aOR: 1.27, 95% CI: 1.13-1.43, p < .001), and 92% as likely to be readmitted up to 90 d postdelivery (aOR 1.92, 95% CI: 1.75-2.11, p < .001). The SCD group also had a longer median LOS, greater total hospital charges, were more likely to experience a postpartum complication, and receive a blood transfusion than the non-SCD group. CONCLUSIONS: SCD in pregnancy is associated with increased inpatient mortality, readmissions, postpartum complications, LOS, and hospital charges.

Rectal Prolapse Repair with Abdominal Fixation Under Sedation and Local or Epidural Anesthesia: Prospective Pilot Study in 10 Elderly Subjects.

Background: Rectal prolapse (RP) is primarily a disease of the elderly, where treatment may be associated with significant postoperative morbidity including that related to anesthesia. Objective: The aim of this study was to evaluate the safety and feasibility of a novel abdominal approach to RP repair under sedation and local anesthesia and to assess short- and long-term clinical outcomes in elderly patients (>70 years). Design Settings: This is a prospective pilot study with 10 patients using a novel RP repair. The anesthesia type was local or epidural with sedation. Follow-up was done at 30 days, 12, and 24 months. Patients: Patients were men and women >70 years of age with RP. Main Outcome Measures: (1) Feasibility: successful completion of RP repair using the novel abdominal approach with laparoscopic assistance. (2) Safety: safety was measured by the incidence of the intraoperative complications (bowel perforation, organ injury, and bleeding requiring blood transfusion). (3) Sedation and local anesthesia feasibility: surgery was safely completed without patient intubation. Results: Ten female patients >70 years of age underwent RP repair using the novel abdominal approach. General anesthesia was not required in any of the 10 patients. Two patients recurred within 6 months. One of the patients with recurrence of RP subsequently underwent laparoscopic rectopexy, and the other was minimal and required no further treatment. One mortality occurred at 3 months unrelated to the procedure. No other anesthetic or surgical intraoperative and postoperative complications were observed. Limitations: This is a single-institution pilot study. Conclusions: Abdominal RP repair under sedation and regional anesthesia appears feasible and safe in elderly patients and may, in the future, provide an effective alternative to current treatment options for RP, avoiding general anesthesia.

Opioid use disorder and maternal outcomes following cesarean delivery: a multistate analysis, 2007-2014.

Aim: To examine the association between opioid use disorder (OUD) and maternal outcomes following cesarean delivery. Methods: Retrospective analysis of over 2.4 million discharge records for in-patient cesarean delivery across five states from 2007 to 2014. Primary outcome was in-hospital mortality. Secondary outcomes included length of stay (LOS) and 30- and 90-day readmission rates. Results: OUD patients were 148% more likely than non-OUD patients to die during hospitalization (adjusted odds ratios [aOR]: 2.48, 95% CI: 1.20, 5.10; p < 0.05). OUD was associated with increased odds of 30-day readmission (aOR: 1.46, 95% CI: 1.30, 1.65; p < 0.001) and 90-day readmission (aOR: 1.70, 95% CI: 1.55, 1.88; p < 0.001); LOS was not significantly different. Conclusion: OUD predicts increased in-patient mortality and odds of 30- and 90-day readmission following cesarean delivery.

Management of pregnancy in women with factor VII deficiency: A case series.

INTRODUCTION: Inherited factor VII deficiency is the most common autosomal recessive inherited bleeding disorder, with an estimated incidence of one per 500 000 cases in the general population. Bleeding manifestations correlate poorly with circulating FVII levels. During pregnancy, increases in FVII levels can occur in women with mild-moderate FVII deficiencies but not in those with severe deficiency. AIM: We present five pregnant patients with FVII deficiency and describe the management during their pregnancies and peripartum periods. METHODS: Retrospective analysis of six pregnancies in five women with FVII deficiency followed during pregnancy and delivery at an academic medical centre between January 2013 and December 2019. RESULTS: Of the five patients, two had severe, one with moderate and two with mild FVII deficiency. Early postpartum haemorrhage (PPH) occurred in two patients. One of the two severe FVII-deficient patients had PPH with a laceration at delivery despite replacement therapy with recombinant factor VII. The other PPH occurred in a patient with mild FVII deficiency who delivered twins by caesarean section under general anaesthesia. Neuraxial anaesthesia was utilized in only one woman with mild deficiency whose FVII level normalized at the end of the pregnancy. CONCLUSIONS: Management of delivery for women with FVII deficiency should be addressed on a case-by-case basis at centres with expertise in rare bleeding disorders, maternal foetal medicine and obstetric anaesthesiology. These management discussions should factor the patient's bleeding history, third trimester PT, FVII level, multiple gestation and mode of delivery.

Putting It All Together: Clinical Considerations in the Care of Critically Ill Obstetric Patients with COVID-19.

Pregnant patients with severe acute respiratory syndrome coronavirus 2, the virus responsible for the clinical condition newly described in 2019 as coronavirus disease 2019 (COVID-19) and illness severity to warrant intensive care have a complex disease process that must involve multiple disciplines. Guidelines from various clinical societies, along with direction from local health authorities, must be considered when approaching the care of an obstetric patient with known or suspected COVID-19. With a rapidly changing landscape, a simplified and cohesive perspective using guidance from different clinical society recommendations regarding the critically-ill obstetric patient with COVID-19 is needed. In this article, we synthesize various high-level guidelines of clinical relevance in the management of pregnant patients with severe disease or critical illness due to COVID-19. KEY POINTS: · When caring for severely ill obstetric patients with COVID-19, one must be well versed in the complications that may need to be managed including, but not limited to adult respiratory distress syndrome with need for mechanical ventilation, approach to refractory hypoxemia, hemodynamic shock, and multiorgan system failure.. · Prone positioning can be done safely in gravid patients but requires key areas of support to avoid abdominal compression.. · For the critically ill obstetric patient with COVID-19, the focus should be on supportive care as a bridge to recovery rather than delivery as a solution to recovery..

Racial and ethnic disparities in severe maternal morbidity and anesthetic techniques for obstetric deliveries: A multi-state analysis, 2007-2014.

STUDY OBJECTIVE: To evaluate racial and ethnic disparities in severe maternal morbidity (SMM) and administered anesthesia techniques. DESIGN: Retrospective cohort study. SETTING: Administrative database study using 2007-2014 data from California, Florida, New York, Maryland, and Kentucky from the State Inpatient Databases (SID), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality (AHRQ). PATIENTS: 6,879,332 parturients aged ≥18 years old who underwent deliveries were identified by International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) codes: V27.0 and V27.1 for singleton deliveries, and V27.2 through V27.8 for multiple births. INTERVENTIONS: Patients who had a singleton or multiple delivery. MEASUREMENTS: Patients were cohorted by race/ethnicity: white (reference category), black, Hispanic, other, or missing. Demographic characteristics and comorbidities were compared. Adjusted odds ratios with generalized linear mixed modeling were calculated for SMM. We also conducted additional exploratory analyses of racial/ethnic disparities in the anesthesia technique used for cesarean deliveries, as well as the use of analgesia in vaginal deliveries. MAIN RESULTS: When controlling for patient demographics, comorbidities, and hospital characteristics, black women were more likely than white women to experience any SMM (adjusted odds ratio: 1.38, 95% CI: 1.35-1.41). This finding was consistent in stratified analyses. Black women were also more likely than white women to receive general anesthesia for cesarean delivery (aOR: 1.44, 95% CI: 1.39-1.49) and to receive no analgesia for vaginal delivery (aOR: 1.45, 95% CI: 1.43-1.47). CONCLUSIONS: Our findings highlight the differences in outcomes and care for black as compared to white parturients related to SMM and administered anesthesia techniques.

A Survey of Intravenous Remifentanil Use for Labor Analgesia at Academic Medical Centers in the United States.

Remifentanil is most commonly offered when neuraxial labor analgesia is contraindicated. There is no consensus regarding the optimal administration, dosing strategy, or requirements for maternal monitoring, which may pose a patient safety issue. This exploratory survey evaluated the current practices regarding remifentanil use for labor analgesia at academic centers in the United States. Of 126 obstetric anesthesia directors surveyed, 84 (67%) responded. In 2014 to 2015, an estimated 36% (95% confidence interval: 25.7-46.3) of centers used remifentanil, most of which did so less than 5 times. Some serious maternal and neonatal respiratory complications occurred, emphasizing that clinical protocols and adequate monitoring are key to ensure maternal and neonatal safety.

Adverse effects of combined spinal-epidural versus traditional epidural analgesia during labor.

OBJECTIVE: To compare two neuraxial block techniques during labor for maternal and fetal effects. METHODS: Women in labor at term with cephalic singleton fetuses were randomized (nonblinded) to receive either labor epidural (EPI) or combined spinal-epidural (CSE) analgesia. Primary outcome was prolonged deceleration (PD) of fetal heart rate. Outcomes also included hypotension, mode of delivery, and efficacy of analgesia by visual analog pain scale (VAPS) before and after block placement. RESULTS: Randomization occurred in 127 patients: 63 received EPI, 64 received CSE. There was no difference in the rate of PD in the EPI group compared with the CSE group (3.2% vs 6.2% respectively; P=0.43, RR 2.0; 95% CI 0.4-9.3), rate of cesarean delivery, or mean epidural duration. VAPS ratings were significantly lower in the CSE group. CONCLUSIONS: There were no differences in the rate of PD or other adverse outcomes. Hypotension occurred more frequently with CSE during labor at term. The study supports both EPI and CSE during labor as safe and effective techniques for neuraxial analgesia.

Oral sodium citrate increases nausea amongst elective Cesarean delivery patients.

PURPOSE: Historically, aspiration of gastric contents with subsequent pneumonia was a major cause of anesthesia-related maternal mortality. Before elective Cesarean delivery, gastric fluid can be neutralized with histamine-2 blockers or with oral sodium citrate. Although sodium citrate is commonly used, many patients dislike its taste. We designed this study to determine whether or not patients are more likely to experience nausea during Cesarean delivery when sodium citrate is administered preoperatively. METHODS: One hundred and twenty-three healthy women carrying a singleton fetus and scheduled for elective Cesarean delivery under spinal anesthesia were randomized to receive either sodium citrate 30 mL p.o. and saline 2 mL i.v. (sodium citrate group), or water 30 mL p.o. and famotidine 20 mg i.v. (famotidine group). Spinal anesthesia consisted of 1.6 mL of 0.75% bupivacaine (12 mg), fentanyl 20 microg, and preservative-free morphine 200 microg. Patients were asked to rate the degree of nausea present at one and five minutes after spinal placement, at the time of uterine exteriorization, and upon arrival to the recovery room. At each time point, the patient's systolic blood pressure and heart rate were recorded. RESULTS: At all recorded intervals, the average degree of nausea was greater in the sodium citrate group compared to the famotidine group. The frequency of nausea was also greater in the sodium citrate group compared with the famotidine group (37% vs 14% respectively, P < 0.05) five minutes after establishment of spinal anesthesia. The frequencies of nausea were not significantly different between groups at other time periods. CONCLUSION: Nausea is more common during Cesarean delivery in women who receive oral sodium citrate rather than i.v. famotidine for aspiration prophylaxis.

Subarachnoid small-dose bupivacaine versus lidocaine for cervical cerclage.

UNLABELLED: Cervical cerclage is often performed as an outpatient procedure under subarachnoid anesthesia. Lidocaine was historically the drug of choice for short procedures but has fallen out of favor because of concerns of transient neurologic symptoms (TNS). We performed this study to determine whether small-dose bupivacaine is an acceptable alternative to lidocaine for cervical cerclage. We randomized 59 women to receive either subarachnoid isobaric lidocaine 30 mg or hyperbaric bupivacaine 5.25 mg. Fentanyl 20 micro g was added to both local anesthetics, and the total volume was diluted to 3 mL with 0.9% saline. Onset and highest dermatomal level of sensory block; quality of anesthesia; hypotension; and times until T12 regression, return of lower extremity motor function, ambulation, and micturition were recorded. Symptoms of TNS were evaluated by telephone interview 24 h after surgery. We did not find any significant difference in onset or recovery times between the groups, with the exception of a longer duration until return of lower extremity motor strength in the lidocaine group. Symptoms consistent with TNS that resolved spontaneously within 48 h were reported by two women in the lidocaine group but by none in the bupivacaine group. We conclude that subarachnoid bupivacaine offers a satisfactory alternative to subarachnoid lidocaine for cervical cerclage. IMPLICATIONS: We found that small-dose subarachnoid bupivacaine (5.25 mg) with fentanyl 20 micro g provides reliable anesthesia for cervical cerclage and exhibits a pharmacodynamic profile similar to that of small-dose lidocaine.

Thrombocytopenia, low molecular weight heparin, and obstetric anesthesia.

The parturient with coagulation defects, whether related to thrombocytopenia or to anticoagulation therapy, presents a unique challenge to the anesthesiologist. The risk of spinal or epidural hematoma in these patients has not been quantified fully but is a factor that one must consider on a case-by-case basis in determining whether neuraxial anesthesia is appropriate for the parturient. Following the guidelines set forth in this article should help reduce the risk of spinal or epidural hematoma without sacrificing the quality of care provided to patients.
