Disparities in postpartum readmission by patient- and hospital-level social risk factors in the United States: a retrospective multistate analysis, 2015-2020.

BACKGROUND: Postpartum readmission is an area of focus for improving obstetric care and reducing costs. We examined disparities in all-cause 30-day postpartum readmission by patient- and hospital-level factors in the United States. METHODS: We conducted a retrospective cohort study using 2015-2020 records from the State Inpatient Databases from four states. Generalized linear mixed models were constructed to estimate the effects of individual patient- and hospital-level factors on adjusted odds of 30-day readmission after controlling for confounders. Stratified analyses by delivery and anesthesia type (New York only) and interaction models were performed. RESULTS: Black mothers were more likely than White mothers to be readmitted within 30-days postpartum (aOR 1.57, 95% CI 1.52 to 1.61). Mothers with public insurance had increased odds of readmission compared with those with private insurance (Medicare: aOR 2.13, 95% CI 1.95 to 2.32; Medicaid: aOR 1.14, 95% CI 1.11 to 1.17). Compared with mothers in the lowest income quartile, those in the highest quartile experienced a 14% lower odds of readmission (aOR 0.86, 95% CI 0.83 to 0.89). There were no significant associations between hospital-level characteristics and readmission. Black mothers were more likely to be readmitted regardless of delivery type and most combinations of delivery and anesthesia type. Black mothers from the highest income quartile were more likely to be readmitted than White mothers from the lowest income quartile. CONCLUSION: Substantial disparities in 30-day postpartum readmissions by patient-level social factors were observed, particularly amongst Black mothers. Action is needed to address and mitigate disparities in postpartum readmission.

United States rural residence is associated with increased acute maternal end-organ injury or mortality after birth: a retrospective multi-state analysis, 2007-2018.

BACKGROUND: Geographic-based healthcare determinants and choice of anesthesia have been shown to be associated with maternal morbidity and mortality. We explored whether differences in maternal outcomes based on maternal residence, and anesthesia type for cesarean and vaginal birth, exist. METHODS: This study was a retrospective multi-state analysis; patient residence was the predictor variable of interest and a composite binary measure of maternal end-organ injury or inpatient mortality was the primary outcome. Our secondary outcomes included a binary measure of anesthesia type for cesarean birth (general vs. neuraxial [NA]) and NA analgesia for vaginal birth (no NA vs. NA). Our predictor variable of interest was patient residency (reference category central metropolitan areas of >1 million population), fringe large metropolitan county, medium metropolitan, small metropolitan, micropolitan, and non-metropolitan or micropolitan county. RESULTS: Women residing in micropolitan (OR 1.17; 95% CI 1.09 to 1.27) and non-metropolitan or micropolitan counties (OR 1.14; 95% CI 1.04 to 1.24) had the highest adjusted increased odds of adverse maternal outcomes. Those residing in suburban, medium, and small metropolitan areas underwent general anesthesia less often during cesarean births than those residing in urban areas. Patients residing in micropolitan rural (OR 2.07; 95% CI 2.02 to 2.12) and non-metropolitan or micropolitan (2.25; 95% CI 2.16 to 2.34) counties underwent vaginal births without NA analgesia more than twice as often as those residing in urban areas. CONCLUSIONS: Rural-urban disparities in maternal end-organ damage and mortality exist and anesthesia choice may play an important role in these disparate outcomes.

Patient race and racial composition of delivery unit associated with disparities in severe maternal morbidity: a multistate analysis 2007-2014.

BACKGROUND: High Black-serving delivery units and high hospital safety-net burden have been associated with poorer patient outcomes. We examine these hospital-level factors and their association with severe maternal morbidity (SMM), independently and as effect modifiers of patient-level factors. METHODS: Using the 2007-2014 State Inpatient Databases (Florida, New York, California, Maryland, Kentucky), we analyzed delivery hospitalizations. We constructed generalized linear mixed models with patient- and hospital-level variables (Black-serving delivery units: high: top 5th percentile; medium: 5th-25th percentile; low: bottom 75th percentile; hospital safety-net burden status defined by insurance status) and report adjusted odds ratios (aOR) and 99% confidence intervals (CI). We repeated our mixed models with stratification and interaction analysis. RESULTS: 6 879 332 delivery hospitalizations were included in the analysis. Deliveries at high (aOR 1.83; 99% CI 1.34 to2.50) or medium (aOR 1.27; 99% CI 1.10 to 1.46) Black-serving delivery units were more likely to have SMM than deliveries at low Black-serving delivery units. Hospital safety-net burden was not significantly associated with SMM. In stratified models by hospital category, deliveries of Black women were associated with an increase in SMM compared with deliveries of White women in all hospital categories. In interaction models, Black women giving birth in high Black-serving delivery units had more than twice the odds of White women in low Black-serving delivery units of experiencing SMM (aOR 2.42; 99% CI 1.90 to 3.08). CONCLUSION: The patient racial/ethnic composition of the delivery unit is associated with adjusted-odds of SMM, both independently and interactively with individual patient race.

Obstructive sleep apnea is associated with adverse maternal outcomes using a United States multistate database cohort, 2007-2014.

BACKGROUND: Obstructive sleep apnea affects approximately 11% of women of reproductive age, although it is often undetected and untreated. Previous studies suggest an association between obstructive sleep apnea and adverse maternal outcomes. Herein, we aim to better characterize the relationship between obstructive sleep apnea and maternal outcomes. METHODS: Using the State Inpatient Databases, we performed a retrospective analysis of parturients ≥18 years old having inpatient deliveries in Florida, New York, California, Maryland, and Kentucky from 2007 to 2014. Outcomes included maternal pre-existing conditions, in-hospital mortality, maternal-fetal conditions and complications, and hospital length of stay >5 days. RESULTS: Our cohort consisted of 6 911 916 parturients of whom 4326 (0.06%) had obstructive sleep apnea. Women with obstructive sleep apnea were more likely to present with pre-existing conditions, such as obesity and pre-pregnancy diabetes. After adjusting for patient- and hospital-level confounders in our multivariate analysis, obstructive sleep apnea status was associated with an increased odds of maternal-fetal conditions and complications, including pre-eclampsia (aOR 2.05, 95% CI 1.87 to 2.26), pulmonary edema (aOR 4.73, 95% CI 2.84 to 7.89), cesarean delivery (aOR 1.96, 95% CI 1.81 to 2.11), early onset delivery (aOR 1.28, 95% CI 1.17 to 1.40), and length of stay >5 days (aOR 2.42, 95% CI 2.21 to 2.65). Obstructive sleep apnea was not significantly associated with a higher risk of in-hospital mortality. CONCLUSIONS: Pregnant women with obstructive sleep apnea have a significantly higher adjusted risk of adverse maternal outcomes compared with women without obstructive sleep apnea.

Management of pregnancy in a patient with severe haemophilia A.

Haemophilia A is a bleeding disorder that has a spectrum of manifestations ranging from persistent bleeding after minor trauma to spontaneous haemorrhage. As an X-linked disease, it has a rare occurrence in females. We report a case of a pregnant patient with severe haemophilia A, who received epidural analgesia during labour. The prepartum, intrapartum and postpartum care of a patient with such a bleeding diathesis is discussed.

Improved epidural analgesia in the parturient in the 30 degree tilt position.

PURPOSE: To compare the incidence of incomplete analgesia when epidural local anesthetic is administered with the parturient supine in a 30 degree leftward tilt or in the left lateral decubitus position. METHODS: After placement of a multiorifice catheter 5 cm into the epidural space, 293 women in active labour were randomly positioned either to the left lateral decubitus position (lateral group) or supine with a 30 degree leftward tilt (tilt group) and then received 13 mL bupivacaine 0.25%. The success of the epidural block was determined by asking the patient if she required additional medication 15 min later. The incidence of complications (fetal heart rate decelerations, hypotension, and ephedrine usage) was noted. RESULTS: In the lateral group, 38% required additional medication compared with 24% in the tilt group (P = 0.006). There were no differences between groups in the incidence of maternal hypotension or fetal heart rate decelerations, but more women (10%) received ephedrine in the lateral than in the tilt group (4%), P = 0.035. CONCLUSIONS: Placing the parturient supine with a 30 degree leftward tilt is associated with a greater success rate of labour epidural analgesia without an increase in complications than in women in the left lateral decubitus position. This advantage should be considered when positioning the parturient after epidural catheter placement.

New closure technique for lateral operative laparoscopic trocar sites. A report of 80 closures.

The reported frequency of incisional hernias, after operative gynecological laparoscopy, at extraumbilical trocar sites is one per 32 puncture sites created by a 12-mm trocar. A new closure technique of suturing with the Grice Needle (Ideas for Medicine, Inc., Clearwater, FL) before removing the trocars was utilized to close 80 lateral trocar sites (42 consecutive laparoscopic myomectomies). The trocar sizes in this study were 12 mm and 18 mm. This is the largest reported series of lateral trocar-site closures. No hematomas or bleeding or incisional hernias have resulted from use of this technique. This closure allows the surgeon to completely close both peritoneum and fascia, of the lateral trocar sites, under direct laparoscopic visualization without the loss of pneumoperitoneum or risk of inadvertent injury to the small bowel.
