Hospital Discharge Codes and Overestimating Severe Maternal Morbidity During Delivery Hospitalization.

Our objective was to identify birth hospitalization severe maternal morbidity (SMM) diagnoses that were also coded during prior encounters and, thus, potentially falsely carried forward as de novo SMM events. This retrospective cohort study included pregnant patients with births between 2016 and 2020. We applied the SMM algorithm to the birth hospitalization and encounters occurring prepregnancy, antepartum, and postpartum. The primary outcome was the rate of SMM diagnoses recorded during the birth hospitalization that were also coded on previous encounters. There were 1,380 (1.8%) birthing patients with SMM. Of patients with SMM codes at the birth hospitalization, 19.0% had the same SMM code during a prior encounter. Certain SMM events may be prone to carry-forward errors and may not signify a de novo birth hospitalization event.

Maternal Morbidity According to Mode of Delivery Among Pregnant Patients With Pulmonary Hypertension.

BACKGROUND: Patients with pulmonary hypertension have a high risk of maternal morbidity and mortality. It is unknown if a trial of labor carries a lower risk of morbidity in these patients compared to a planned cesarean delivery. The objective of this study was to examine the association of delivery mode with severe maternal morbidity events during delivery hospitalization among patients with pulmonary hypertension. METHODS: This retrospective cohort study used the Premier inpatient administrative database. Patients delivering ≥25 weeks gestation from January 1, 2016, to September 30, 2020, and with pulmonary hypertension were included. The primary analysis compared intended vaginal delivery (ie, trial of labor) to intended cesarean delivery (intention to treat analysis). A sensitivity analysis was conducted comparing vaginal delivery to cesarean delivery (as treated analysis). The primary outcome was nontransfusion severe maternal morbidity during the delivery hospitalization. Secondary outcomes included blood transfusion (4 or more units) and readmission to the delivery hospital within 90 days from discharge from delivery hospitalization. RESULTS: The cohort consisted of 727 deliveries. In the primary analysis, there was no difference in nontransfusion morbidity between intended vaginal delivery and intended cesarean delivery groups (adjusted odds ratio [aOR], 0.75; 95% confidence interval [CI], 0.49-1.15). In secondary analyses, intended cesarean delivery was not associated with blood transfusion (aOR, 0.71; 95% CI, 0.34-1.50) or readmission within 90 days (aOR, 0.60; 95% CI, 0.32-1.14). In the sensitivity analysis, cesarean delivery was associated with a 3-fold higher risk of nontransfusion morbidity compared to vaginal delivery (aOR, 2.64; 95% CI, 1.54-3.93), a 3-fold higher risk of blood transfusion (aOR, 3.06; 95% CI, 1.17-7.99), and a 2-fold higher risk of readmission within 90 days (aOR, 2.20; 95% CI, 1.09-4.46) compared to vaginal delivery. CONCLUSIONS: Among pregnant patients with pulmonary hypertension, a trial of labor was not associated with a higher risk of morbidity compared to an intended cesarean delivery. One-third of patients who required an intrapartum cesarean delivery had a morbidity event, demonstrating the increased risk of adverse events in this group.

Severe Maternal Morbidity According to Mode of Delivery Among Pregnant Patients With Cardiomyopathies.

BACKGROUND: Women with cardiomyopathies are at risk for pregnancy complications. The optimal mode of delivery in these patients is guided by expert opinion and limited small studies. OBJECTIVES: The objective of this study is to examine the association of delivery mode with severe maternal morbidity events during delivery hospitalization and readmissions among patients with cardiomyopathies. METHODS: The Premier inpatient administrative database was used to conduct a retrospective cohort study of pregnant patients with a diagnosis of a cardiomyopathy. Utilizing a target trial emulation strategy, the primary analysis compared outcomes among patients exposed to intended vaginal delivery vs intended cesarean delivery (intention to treat). A secondary analysis compared outcomes among patients who delivered vaginally vs by cesarean (as-treated). Outcomes examined were nontransfusion severe maternal morbidity during the delivery hospitalization, blood transfusion, and readmission. RESULTS: The cohort consisted of 2,921 deliveries. In the primary analysis (intention to treat), there was no difference in nontransfusion morbidity (adjusted OR [aOR]: 1.17; 95% CI: 0.91-1.51), blood transfusion (aOR: 1.27; 95% CI: 0.81-1.98), or readmission (aOR: 1.03; 95% CI: 0.73-1.44) between intended vaginal delivery and intended cesarean delivery. In the as-treated analysis, cesarean delivery was associated with a 2-fold higher risk of nontransfusion morbidity (aOR: 2.44; 95% CI: 1.85-3.22) and blood transfusion (aOR: 2.26; 95% CI: 1.34-3.81) when compared with vaginal delivery. CONCLUSIONS: In patients with cardiomyopathies, a trial of labor does not confer a higher risk of maternal morbidity, blood transfusion, or readmission compared with planned cesarean delivery.

Maternal and Pregnancy Outcomes Following Heart Transplantation in the United States.

BACKGROUND: Improved survival following heart transplantation (HT) has led to more recipients contemplating pregnancy, but data on outcomes are limited. OBJECTIVES: The authors used a national data set to investigate and describe outcomes of pregnancies and deliveries in the United States in HT recipients. METHODS: Diagnosis and procedure codes from the 2010-2020 Nationwide Readmissions Database identified delivery hospitalizations, history of HT, comorbid conditions, and outcomes. The authors compared rates of severe maternal morbidity (SMM), nontransfusion SMM, cardiovascular SMM (cSMM), and preterm birth from delivery hospitalization between HT recipients and no-HT recipients. The authors evaluated readmission to 330 days postpartum. Logistic and proportional hazard regressions were performed, adjusting for age, socioeconomic and facility characteristics, and clinical comorbidities. RESULTS: Among 19,399,521 deliveries, 105 were HT recipients. Compared with no-HT, HT recipients were at higher risk for all SMM (24.8% vs 1.7%), nontransfusion SMM (20.8% vs 0.7%), cSMM (7.3% vs 0.12%), and preterm birth (43.3% vs 8.2%), all P < 0.001. In adjusted analyses, HT recipients had 16-fold greater odds of SMM, 28-fold greater odds of nontransfusion SMM, 38-fold greater odds of cSMM, and 7-fold greater odds of preterm birth. HT recipients had higher morbidity rates during delivery hospitalization and higher readmission rates within 1 year following delivery (26.9% vs 3.8%; adjusted HR: 6.03 [95% CI: 3.73-9.75]). CONCLUSIONS: Delivery with history of HT is associated with significantly increased rates of SMM, preterm birth, and hospital readmission. These results provide data regarding pregnancy outcomes for use when counseling patients with HT history who are considering pregnancy or who are pregnant.

Practice Advisory for Preoperative and Intraoperative Pain Management of Cardiac Surgical Patients: Part 2.

Pain after cardiac surgery is of moderate to severe intensity, which increases postoperative distress and health care costs, and affects functional recovery. Opioids have been central agents in treating pain after cardiac surgery for decades. The use of multimodal analgesic strategies can promote effective postoperative pain control and help mitigate opioid exposure. This Practice Advisory is part of a series developed by the Society of Cardiovascular Anesthesiologists (SCA) Quality, Safety, and Leadership (QSL) Committee's Opioid Working Group. It is a systematic review of existing literature for various interventions related to the preoperative and intraoperative pain management of cardiac surgical patients. This Practice Advisory provides recommendations for providers caring for patients undergoing cardiac surgery. This entails developing customized pain management strategies for patients, including preoperative patient evaluation, pain management, and opioid use-focused education as well as perioperative use of multimodal analgesics and regional techniques for various cardiac surgical procedures. The literature related to this field is emerging, and future studies will provide additional guidance on ways to improve clinically meaningful patient outcomes.

Practice Advisory for Preoperative and Intraoperative Pain Management of Thoracic Surgical Patients: Part 1.

Pain after thoracic surgery is of moderate-to-severe intensity and can cause increased postoperative distress and affect functional recovery. Opioids have been central agents in treating pain after thoracic surgery for decades. The use of multimodal analgesic strategies can promote effective postoperative pain control and help mitigate opioid exposure, thus preventing the risk of developing persistent postoperative pain. This practice advisory is part of a series developed by the Society of Cardiovascular Anesthesiologists (SCA) Quality, Safety, and Leadership (QSL) Committee's Opioid Working Group. It is a systematic review of existing literature for various interventions related to the preoperative and intraoperative pain management of thoracic surgical patients and provides recommendations for providers caring for patients undergoing thoracic surgery. This entails developing customized pain management strategies for patients, which include preoperative patient evaluation, pain management, and opioid use-focused education as well as perioperative use of multimodal analgesics and regional techniques for various thoracic surgical procedures. The literature related to this field is emerging and will hopefully provide more information on ways to improve clinically relevant patient outcomes and promote recovery in the future.

Anesthetic Care of the Pregnant Patient With Cardiovascular Disease: A Scientific Statement From the American Heart Association.

The pregnancy-related mortality rate in the United States is excessively high. The American Heart Association is dedicated to fighting heart disease and recognizes that cardiovascular disease, preexisting or acquired during pregnancy, is the leading cause of maternal mortality in the United States. Comprehensive scientific statements from cardiology and obstetrics experts guide the treatment of cardio-obstetric patients before, during, and after pregnancy. This scientific statement aims to highlight the role of specialized cardio-obstetric anesthesiology care, presenting a systematic approach to the care of these patients from the anesthesiology perspective. The anesthesiologist is a critical part of the pregnancy heart team as the perioperative physician who is trained to prevent or promptly recognize and treat patients with peripartum cardiovascular decompensation. Maternal morbidity is attenuated with expert anesthesiology peripartum care, which includes the management of neuraxial anesthesia, inotrope and vasopressor support, transthoracic echocardiography, optimization of delivery location, and consideration of advanced critical care and mechanical support when needed. Standardizing the anesthesiology approach to patients with high peripartum cardiovascular risk and ensuring that cardio-obstetrics patients have access to the appropriate care team, facilities, and advanced cardiovascular therapies will contribute to improving peripartum morbidity and mortality.

Maternal Cardiovascular Morbidity Events Following Preeclampsia: A Retrospective Cohort Study.

BACKGROUND: Patients with preeclampsia are at high risk for long-term cardiovascular events, yet the short-term, acute cardiovascular complications that follow preeclampsia are understudied. The objective of this study was to compare the short-term, acute maternal cardiovascular morbidity events after delivery among patients with a diagnosis of preeclampsia versus those without this diagnosis. METHODS: In this retrospective cohort study, the Premier inpatient database was used to examine a cohort of obstetric patients older than 18 years, who delivered from January 1, 2016, to September 30, 2020. A diagnosis of preeclampsia and preeclampsia with severe features during delivery hospitalization were the exposures of interest. The primary outcome was a composite of maternal cardiovascular morbidity events during delivery hospital admission. The secondary outcome was the occurrence of maternal cardiovascular morbidity events during a readmission within 90 days of delivery hospitalization. RESULTS: In total, 4,488,759 patients met inclusion criteria, of which 158,114 (3.5%) were diagnosed with preeclampsia without severe features, and 117,940 (2.6%) with preeclampsia with severe features. Adjusted odds of maternal cardiovascular morbidity events were higher in patients with preeclampsia and in those with preeclampsia with severe features compared with those without preeclampsia during delivery hospitalization (adjusted odds ratio [OR] [95% confidence interval {CI}] 1.87 [1.78-1.97] and 4.74 [4.44-5.05], respectively) and within 90 days (adjusted OR [95% CI] 2.01 [1.83-2.21] and 2.32 [2.10-2.57], respectively). CONCLUSIONS: Patients with both preeclampsia and preeclampsia with severe features have higher rates of maternal cardiovascular morbidity events than those without preeclampsia. Future studies are necessary to examine which patients with preeclampsia are at highest risk for cardiovascular complications.

Pregnancy-Associated Extracorporeal Membrane Oxygenation in the United States.

OBJECTIVE: The use of extracorporeal membrane oxygenation (ECMO) therapy has increased in the adult population. Studies from the H1N1 influenza pandemic suggest that ECMO deployment in pregnancy is associated with favorable outcomes. With increasing numbers of pregnant women affected by COVID-19 (coronavirus disease 2019) and potentially requiring this life-saving therapy, we sought to compare comorbidities, costs, and outcomes between pregnancy- and nonpregnancy-associated ECMO therapy among reproductive-aged female patients. STUDY DESIGN: We used the 2013 to 2019 National Readmissions Database. Diagnosis and procedural coding were used to identify ECMO deployment, potential indications, comorbid conditions, and pregnancy outcomes. The primary outcome was in-hospital mortality during the patient's initial ECMO stay. Secondary outcomes included length of stay and hospital charges/costs, occurrence of thromboembolic or bleeding complications during ECMO hospitalization, and mortality and readmissions up to 330 days following ECMO stay. Univariate and multivariate regression models were used to model the associations between pregnancy status and outcomes. RESULTS: The sample included 324 pregnancy-associated hospitalizations and 3,805 nonpregnancy-associated hospitalizations, corresponding to national estimates of 665 and 7,653 over the study period, respectively. Pregnancy-associated ECMO had lower incidence of in-hospital death (adjusted odds ratio [aOR]: 0.56, 95% confidence interval [CI]: 0.41-0.75) and bleeding complications (aOR: 0.67, 95% CI: 0.49-0.93). Length of stay was significantly shorter (adjusted rate ratio (aRR): 0.86, 95% CI: 0.77-0.96) and total hospital costs were less (aRR: 0.83, 95% CI: 0.75-0.93). Differences in the incidence of thromboembolic events (aOR: 1.04, 95% CI: 0.78-1.38) were not statistically significant. CONCLUSION: Pregnancy-associated ECMO therapy had lower incidence of in-hospital death, bleeding complications, total inpatient cost, and length of stay when compared with nonpregnancy-associated ECMO therapy without increased thromboembolic complications. Pregnancy-associated ECMO therapy should be offered to eligible patients. KEY POINTS: · Pregnancy-related ECMO use was compared with nonpregnant use.. · Outcomes were equal or favored pregnancy-related deployment.. · These data may be useful when considering ECMO use in pregnancy..

Image Acquisition Method for the Sonographic Assessment of the Inferior Vena Cava.

Over the past several decades, clinicians have incorporated several applications of diagnostic point-of-care ultrasound (POCUS) into medical decision-making. Among the applications of POCUS, imaging the inferior vena cava (IVC) is practiced by a wide variety of specialties, such as nephrology, emergency medicine, internal medicine, critical care, anesthesiology, pulmonology, and cardiology. Although each specialty uses IVC data in slightly different ways, most medical specialties, at minimum, attempt to use IVC data to make predictions about intravascular volume status. While the relationship between IVC sonographic data and intravascular volume status is complex and highly context-dependent, all clinicians should collect the sonographic data in standardized ways to ensure repeatability. This paper describes standardized IVC image acquisition including patient positioning, transducer selection, probe placement, image optimization, and the pitfalls and limitations of IVC sonographic imaging. This paper also describes the commonly performed anterior IVC long-axis view and three other views of the IVC that can each provide helpful diagnostic information when the anterior long-axis view is difficult to obtain or interpret.

For better care we need better data: towards a national obstetrics registry.

Unacceptably high rates of severe maternal morbidity and mortality in the United States and stark racial disparities in outcomes are generating efforts to improve both research capacity and quality improvement in obstetrical care. Comprehensive, high-quality datasets on which to build these efforts are crucial to the success of obstetrical quality improvement efforts. However, existing data sources in obstetrics have notable limitations. Other medical and surgical specialties have addressed similar challenges through the creation of national registries, and we argue that obstetrics must take the same approach to improve outcomes. In this article, we summarized the current availability and limitations of large-scale data in obstetrics research and compared the data with registries developed in other specialties. Moreover, we have outlined the guiding principles for the development of a national obstetrics registry and have proposed future directions.

Peripartum considerations for women with cardiac disease.

PURPOSE OF REVIEW: The aim of this review of cardiac disease in pregnancy is to delineate current best practices and highlight emerging themes in the literature. RECENT FINDINGS: Cardiovascular disease is the leading cause of death among pregnant women in the United States. Many clinicians and institutions have developed care pathways to approach care in these high-risk patients including highly coordinated multidisciplinary teams. The diagnosis of pulmonary hypertension is the greatest risk factor for an adverse event in pregnant women. Vaginal delivery, with good neuraxial anesthesia, is usually the preferred mode of delivery in women with cardiac disease, although the rate of cesarean delivery is higher among women with heart disease. SUMMARY: The leading cause of morbidity and mortality in pregnant women is cardiac disease. Preconception counseling is useful for optimizing patients for pregnancy and setting appropriate expectations about care and outcomes. Ensuring that women are cared for in centers with appropriate multidisciplinary resources is key for improving outcomes for cardio-obstetric patients.

Obstetric Anesthesia and Heart Disease: Practical Clinical Considerations.

Maternal morbidity and mortality as a result of cardiac disease is increasing in the United States. Safe management of pregnancy in women with heart disease requires appropriate anesthetic, cardiac, and obstetric care. The anesthesiologist should risk stratify pregnant patients based upon cardiac disease etiology and severity in order to determine the appropriate type of hospital and location within the hospital for delivery and anesthetic management. Increased intrapartum hemodynamic monitoring may be necessary and neuraxial analgesia and anesthesia is typically appropriate. The anesthesiologist should anticipate obstetric and cardiac emergencies such as emergency cesarean delivery, postpartum hemorrhage, and peripartum arrhythmias. This clinical review answers practical questions for the obstetric anesthesiologist and the nonsubspecialist anesthesiologist who regularly practices obstetric anesthesiology.

Introduction of an Analgesia Prescription Guideline Can Reduce Unused Opioids After Cardiac Surgery: A Before and After Cohort Study.

OBJECTIVE(S): The authors aimed to assess whether the introduction of a tailored Analgesia Prescription Guideline would decrease the amount of unused opioid following discharge from cardiac surgery. DESIGN: Prospective, observational, before and after study. SETTING: Quaternary care university hospital. PARTICIPANTS: A total of 191 participants who underwent cardiac surgery requiring midline sternotomy and cardiopulmonary bypass. There were 99 participants in the before cohort (prior to introduction of the Analgesia Prescription Guideline), and 92 participants in the after cohort (after introduction of the Analgesia Prescription Guideline). INTERVENTIONS: Using prospectively collected observational data on participant opioid consumption in the before cohort, a tailored Analgesia Prescription Guideline was developed. This guideline then was introduced to all opioid-prescribing providers in the cardiothoracic surgery department. Prospective data then were collected in the after cohort of participants. Opioid prescription practices and opioid consumption between the two groups then were compared. MEASUREMENTS AND MAIN RESULTS: Opioid prescriptions were given to 62/99 participants (63%) in the before cohort, and 48/92 (52%) in the after cohort (rate difference 0.1, CI 95% -0.26, 0.046). In the before cohort, the mean (± standard deviation) number of opioid tablets prescribed, used, and leftover was 26 (±10), 11 (±10), and 15 (±12), respectively. In the after cohort, the mean number of opioid tablets prescribed, used, and leftover was 18 (mean difference -8, CI 95% -12, -5), 10 (mean difference -1, CI 95% -5, 3), and 8 (mean difference -7, CI 95% -11, -3), respectively. There were 110/191 (58%) participants using no opioids following discharge, and 10/191 (5%) still using opioids two weeks after discharge. There were no differences between groups with regard to demographics, opioid-related side effects, pain scores, satisfaction, opioid storage. and disposal practices. CONCLUSIONS: The development and implementation of a tailored Analgesia Prescription Guideline decreased the amount of opioids prescribed after cardiac surgery and resulted in lower numbers of unused leftover opioid tablets in the community. Patient comfort and satisfaction scores remained high.

Check the Blood Pressure!: An Educational Tool for Anesthesiology Trainees Converting Epidural Labor Analgesia to Cesarean Delivery Anesthesia.

Recognition and treatment of maternal hypotension during epidural anesthesia administration for intrapartum cesarean delivery preserves maternal-fetal perfusion. A case that required quality assurance review uncovered lapses in maternal hemodynamic monitoring during the transition to intrapartum cesarean delivery anesthesia. To address this, a practice outline was designed for trainee's education describing intrapartum epidural dosing for cesarean delivery and adequate blood pressure monitoring. The time-lapse between epidural dosing and subsequent blood pressure was evaluated before and after the introduction of our educational tool. The time-lapse between blood pressure measures decreased to <10 minutes (10.78-13.92 vs 8.8-9.76 minutes).

Adding to the Denominator: A Case Report of Neuraxial Anesthesia for Cesarean Delivery in the Setting of Hemolysis, Elevated Liver Enzyme, Low Platelet, Thrombocytopenia, and Pulmonary Hypertension.

The acceptable platelet count for the safe provision of neuraxial anesthesia in obstetric patients is unknown. Comorbidities may sway a provider to perform neuraxial anesthesia, despite thrombocytopenia, as the putative risk of spinal-epidural hematoma may not outweigh the risks associated with general anesthesia. The case of a 22-year-old nulliparous woman undergoing a cesarean delivery with a new diagnosis of pulmonary hypertension and right heart failure, compounded with thrombocytopenia and possible Hemolysis, Elevated Liver Enzyme, and Low Platelet (HELLP) syndrome, is presented. Risks and benefits of general versus neuraxial anesthesia in this specific setting are reviewed.
