Maternal and fetal outcomes among pregnant women with endometriosis.

Endometriosis, a condition in which endometrial-like tissue grows outside of the uterus, is a common disorder among women of reproductive-age. The objective of the study is to examine the associations between endometriosis in pregnancy and adverse maternal and newborn events. Data from the 1999-2019 Healthcare Cost and Utilization Project, Nationwide Inpatient Sample, which is from the United States, were used to perform a retrospective cohort study. Associations between endometriosis and maternal and newborn outcomes were examined using multivariate logistic regression models adjusted for baseline maternal characteristics. We identified 14,956 individuals with endometriosis and 16,911,497 individuals without endometriosis. The prevalence of endometriosis in pregnancy rose substantially from 34.9 to 160.6 per 100,000 births between 1999 and 2019. Individuals with endometriosis were more likely older in age, of Caucasian ethnicity, belonged to higher income quartiles, had private insurance, smoked, and were obese. Endometriosis in pregnancy was associated with greater odds of pre-eclampsia, gestational diabetes, placenta previa, placental abruption, preterm birth, chorioamnionitis, and postpartum hemorrhage. Growth restriction and congenital anomalies were more frequent among newborns born to individuals with endometriosis. Endometriosis in pregnancy renders individuals and their newborns at greater risk for poor outcomes in pregnancy. Hence, it is prudent for obstetrical care providers to be aware of the adverse events associated with endometriosis and to closely follow the pregnancies of women with this condition.

Measuring Hospital Inpatient Procedure Access Inequality in the United States

Abstract Geographic disparities in access to inpatient procedures are a significant issue within the U.S. healthcare system. This study introduces the Procedure Access Inequality (PAI) index, a standardized metric to quantify these disparities while adjusting for disease prevalence. Using data from the Healthcare Cost and Utilization Project State Inpatient Databases, we analyzed inpatient procedure data from 18 states between 2016 and 2019. The PAI index reveals notable variability in access inequality across different procedures, with minimally invasive and newer procedures exhibiting higher inequality. Key findings indicate that procedures such as skin grafts and minimally invasive gastrectomy have the highest PAI scores, while cesarean sections and percutaneous coronary interventions have the lowest. The study highlights that higher inequality is associated with greater market concentration and in particular, fewer hospitals offering these procedures. These findings emphasize the need for targeted policy interventions to address procedural access disparities to promote more equitable healthcare delivery across the United States.

Migraine and its Association with Stroke in Pregnancy: A National Examination.

Background: Migraine prevalence has been estimated to be as high as 25% during reproductive years. Despite this, and the known significantly lower odds of acute stroke being correctly diagnosed among women versus men, little is known about the migraine-stroke connection in this vulnerable population. Our study seeks to provide a consolidated examination of cerebrovascular and obstetric complications of migraines in pregnant women and to evaluate the role of concurrent comorbidities. Methods: We utilized the 2016-2020 Healthcare Cost and Utilization Project's National Inpatient Sample with the International Classification of Diseases, 10th Revision diagnostic codes to compare pregnant patients with migraines with those without migraines. Multivariable logistic regression was used to examine the incidence of subtypes of stroke while controlling for confounding variables. Results: Overall, 19,825,525 pregnant patients were evaluated; 219,175 (1.1%) had a concomitant diagnosis of migraine. Pregnant patients with migraines were more likely to suffer ischemic (0.1% versus 0.0%) or hemorrhagic stroke (0.3% versus 0.1%). On multivariate analysis, acute ischemic stroke was most strongly associated with migraine with aura (odds ratio [OR], 23.26; 95% confidence interval [CI], 18.46-29.31), followed by migraine without aura (OR, 8.15; 95% CI, 4.79-13.88). Conclusions: Pregnant women with migraine are at a significantly increased risk for both ischemic and hemorrhagic stroke. Pregnant women with migraines should be cautioned that they may be at an increased risk of stroke, particularly if they are experiencing an aura, and encouraged to contact their medical providers to rule out neurological complications.

The Effect of Medicaid Expansion on Access to Anti-incontinence Surgery

Importance Medicaid expansion broadened access to care; however, limited data about the effect on access to anti-incontinence surgical procedures exist. Objective Since the Affordable Care Act (ACA) Medicaid expansion in 2014, some regions have had more states adopt expansion (NE—Northeast, W—West) than other regions (S—South, MW—Midwest). We aimed to determine if the proportion of Medicaid funded anti-incontinence procedures increased after Medicaid expansion and whether increases were different by U.S. region. Study Design This was a retrospective cohort study. Results The 2012–2018 Healthcare Cost and Utilization Project National Inpatient Sample was reviewed for anti-incontinence surgical procedures. Medicaid supported surgical procedures were compared by region and year, and among marginalized populations. During the study period 66,510 surgical procedures were performed. Medicaid as a primary payer for anti-incontinence procedures increased from 10% to 12% (P = <0.001) between 2012 and 2018. The percentage of Medicaid supported procedures performed in the NE (13%) and W (17%) were greater than MW (9%) and S (8%). Procedures among Black, Hispanic or lowest income quartile patients were lowest in the S and did not increase after expansion during the study period (2012 vs 2018, all P = NS). When controlling for confounders, the MW (odds ratio [OR] 0.58; 95% CI 0.46–0.74) and S (OR 0.33; 95% CI 0.26–0.42) were less likely to have Medicaid covered surgical procedures compared to the NE and W (OR 1.04; 95% CI 0.84–1.29). Conclusions Nationally, the percentage of Medicaid-supported anti-incontinence procedures increased after expansion. Northeast and W access to procedures increased, and access by marginalized populations broadened, while the S and MW had the most limited proportion of anti-incontinence surgical procedures covered by Medicaid.

Association between hospital type and length of stay and readmissions for young adults with complex chronic diseases.

There is a paucity of information around whether hospital length of stay and readmission rates differ based upon hospital type for adolescents and young adults (AYA) with complex chronic diseases (CCDs). To measure the association between hospital type and readmission rates and index admission LOS among AYA with CCDs. We performed a retrospective cross-sectional study of 2017 Healthcare Cost and Utilization Project State Inpatient Databases, including patients 12-25 years old with cystic fibrosis (CF), sickle cell disease (SCD), spina bifida (SB), inflammatory bowel disease (IBD), and diabetes mellitus (DM). Index hospitalizations were categorized by hospital type (pediatric hospitals [PHs], adult hospitals with pediatric services [AHPSs], and adult hospitals without pediatric services [AHs]), CCD, and age group. We compared case-mix adjusted 30-day readmission rates and differences in index admission LOS between hospital types. Adult hospitals without pediatric services exhibited higher readmission rates (25.4%) than AHPS (22.9%) and PH (15.1%). Compared to patients with CF admitted to AH, lower readmission rates were associated with longer LOS at both AHPS (relative ratio [RR]: 1.25, 95% confidence interval [CI]: 1.02-1.55) and PH (RR: 1.59, 95% CI: 1.28-1.97). Patients with DM admitted to AHPS (odds ratio [OR]: 0.75, 95% CI: 0.62-0.91) and PH (OR: 0.47, 95% CI: 0.31-0.71) also demonstrated lower readmission rates than those admitted to AH. For AYA with CCD, hospital type is associated with differences in readmission rates and LOS. Lower readmission rates at hospitals with pediatric services compared to adult hospitals without pediatric services suggest hospital type has a significant impact on outcomes.

Characteristics associated with adult non-fatal opioid and stimulant overdose and substance use disorder emergency department visits in Michigan

BackgroundUnderstanding risk factors for emergency department (ED) visits for overdose and substance use disorder (SUD) can inform prevention efforts. Few studies have considered non-fatal opioid overdoses, stimulant overdoses and SUD, and limited data exists by overdose intentionality and by sex. MethodsWe conducted a serial cross-sectional study with Healthcare Cost and Utilization Project Michigan (MI) 2019–2020 ED discharge data (n=5,716,716). Primary outcomes included non-fatal opioid overdoses, non-fatal stimulant overdoses, and SUD primary diagnoses in a single ED visit. We examined demographic and socioeconomic factors associated with study outcomes using binary and multinomial logistic regression (for overdose intentionality) models, which estimated adjusted odds ratios (AOR) and 95 % confidence intervals (CI). ResultsAmong all MI discharges, 13,908, 1,379, and 23,462 were nonfatal opioid, stimulant, or SUD overdose visits, respectively. Lower median household income (vs. higher income), male sex (vs. female), metropolitan county of residence (vs. small urban/rural), and Medicaid (vs. private insurance) were associated with increased odds of all outcomes. For example, ORs(95 % CIs) for Medicaid were 4.41(4.18,4.65), 2.25(1.95,2.60), and 2.80(2.70,2.91) for opioid overdoses, stimulant overdoses, and SUD, respectively. All outcomes had the highest increased odds in ages 28–32 years compared to 18–22 years. Stratification by sex and non-fatal overdose intentionality modified some associations, with the strongest associations observed for non-fatal opioid overdoses. ConclusionsMale sex, Medicaid, and race/ethnicity were consistently associated with all outcomes similarly, but other characteristics varied in patterns, strengths of association, and statistical significance by outcome groups, sex, and non-fatal opioid or stimulant overdose intentionality.

Obstetric and neonatal outcomes in women with Ankylosing spondylitis - an evaluation of a population database

BackgroundAnkylosing Spondylitis (AS) is a systemic chronic rheumatic disease characterized by involvement of the axial skeletal and sacroiliac joints. Although this disease is not rare amongst women of reproductive age, data regarding pregnancy outcomes have demonstrated conflicting results. We therefore aimed to compare pregnancy and perinatal outcomes between women who suffered from AS to those who did not.MethodsA retrospective cohort study using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). Included in the study were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. Women with an ICD-9 diagnosis of AS before or during pregnancy were compared to those without. Pregnancy, delivery, and neonatal outcomes were compared between the two groups using multivariate logistic regression models adjusting for potential confounders.ResultsA total of 9,096,788 women were inclusion in the analysis. Amongst them, 383 women (3.8/100,000) had a diagnosis of AS and the rest were controls. Women with AS, compared to those without, were more likely to be older; Caucasian; from higher income quartiles; suffer from thyroid disorders, and have multiple pregnancies (p < 0.001, all). After adjusting for confounders, patients in the AS group, compared to those without, had a higher rate of cesarean delivery (CD) (aOR 1.47, 95% CI 1.14–1.91, p = 0.003); gestational diabetes (aOR 1.55, 95% CI 1.02–2.33, p = 0.038); and placenta previa (aOR 3.6, 95% CI 1.6–8.12, p = 0.002). Regarding neonatal outcomes, patients with AS, compared to those without, had a higher rate of small-for-gestational-age (SGA) neonates (aOR 2.19, 95% CI 1.22–3.93, p = 0.009); and intrauterine fetal death (IUFD) (aOR 3.46, 95% CI 1.11–10.83, p = 0.033).ConclusionWomen diagnosed with AS have an increased risk of obstetric complications, including CD, as well as an increased risk of SGA and IUFD.

Preoperative Care Intensity and Cost for Renal Colic: Implications for Surgical Value-Based Reforms.

The aim of this study was to identify preoperative patient/facility factors associated with postoperative and total episode-related costs using renal colic as a model surgical condition to improve value-based payment models. Using state Healthcare Cost and Utilization Project data, we performed a retrospective cohort study examining perioperative costs for individuals presenting to an emergency department for renal colic and who ultimately underwent definitive surgical management. We estimated multivariable ordered and binary logistic regressions to examine the association between preoperative and operative cost quartiles on the probability of specific postoperative cost quartiles after accounting for hospital and individual factors. We also performed logistic regressions to identify patients who deviated from predicted perioperative cost pathways. Among 2736 individuals included in our analysis, episode-related costs ranged from $4536 (bottom quartile) to $26,662 (top quartile). Individuals in the highest preoperative cost quartile experienced an 11.7% higher probability of remaining in the highest postoperative cost quartile relative to those in the lowest preoperative cost quartile (95% CI, 0.0709-0.163; P < .001). Delays in surgery (95% CI, 0.0869-0.163; P < .001) and Medicaid vs private insurance (95% CI, 0.01-0.0728; P < .01) were associated with a 12.5% and 4.1% higher probability of being in the top quartile of preoperative costs, respectively. Treating facility experience with value-based payment models did not influence perioperative costs. Using renal colic as a model surgical condition, our novel findings suggest that preoperative costs are associated with both postoperative and total episode-related costs and should be accounted for when designing future value-based payment models.

Congenital Anomalies of the Gastrointestinal Tract inConjunction of Congenital Heart Diseases in Infants With Trisomy 21.

Infants with Trisomy 21 are known to have increased incidence congenital anomalies including congenital heart diseases (CHD) and congenital gastrointestinal anomalies. It is not known if there are patterns of coexistence. To examine the coexistence of CHD with various gastrointestinal anomalies in infants with Trisomy 21. We assessed a sample of infants with Trisomy 21 from the National Inpatient Sample (NIS), and its KID subversion, produced by the Healthcare Cost and Utilization Project for 2003-2015. We identified CHD using international classification of diseases version 9 (ICD9) and categorized them into four groups: left sided lesions, right sided lesions, conotruncal lesions, and shunt lesions. We identified small intestinal atresia and Hirschsprung disease with ICD9 codes. The sample included 81,561 newborn infants diagnosed with Trisomy 21; 45% of them had CHD; 4.7% had small intestinal atresia, and 1.6% had Hirschsprung disease. All subcategories of CHD were associated with increased incidence of both small intestinal atresia and Hirschsprung disease, p value < 0.05 compared to infants with Trisomy 21 who did not have CHD. Among infants with Trisomy 21, the presence of CHD increased the odds of a concomitant congenital GI anomaly.

Mitigating Risk of Acute Kidney Injury Among Children With Methicillin-resistant Staphylococcus aureus Osteomyelitis.

Children with acute hematogenous osteomyelitis (AHO) from methicillin-resistant Staphylococcus aureus (MRSA) are treated with vancomycin despite the risk of acute kidney injury (AKI). This study evaluates the rate of AKI and resource utilization for children with or without AKI when vancomycin is used in this setting. Children with MRSA AHO treated with vancomycin were retrospectively studied. AKI was assessed by clinical diagnosis and Kidney Disease Improving Global Outcomes (KDIGO) criteria. Cohorts of children with or without AKI were compared for differences in treatment, resource utilization, and outcomes. Multivariate logistic regression analysis assessed factors associated with risk for AKI. Cost analysis was performed using the Pediatric Health Information System and Healthcare Cost and Utilization Project databases. Among 85 children studied, 14 (16.5%) had chart-diagnosed AKI and 24 (28.2%) met KDIGO criteria. Children with AKI had more febrile days and higher thrombosis rates. They had longer vancomycin treatment (8 vs 5d), higher troughs (27.8 vs 17.5mg/L), and prolonged hospitalization (19.9 vs 11.1d). Multivariate analysis found a maximum vancomycin trough level (odds ratio: 1.05, P = 0.003) with a cutoff of 21.7mg/L predicted AKI.Only 2 of 20 (10%) children who had MRSA isolates with a minimum inhibitory concentration of 2 achieved therapeutic vancomycin levels. Pediatric Health Information System data of 3133 children with AHO treated with vancomycin identified 75 (2.4%) with AKI who had significantly longer lengths of stay (13 vs 7d) and higher billed charges ($117K vs $51K) than children without AKI. Chart documentation of AKI (16.5%) grossly underestimated KDIGO-defined occurrence (28.2%). This study showed that vancomycin-associated AKI required substantially greater resource utilization and higher health care costs. Lowering the targeted trough range, shortening the duration of vancomycin therapy, and considering alternative antibiotics when minimum inhibitory concentration ≥2 will reduce the risk and cost of AKI among children with MRSA AHO. Level III-retrospective comparative therapeutic study.

Assessing racial disparities in gender-affirming surgery utilization and hospital-level experience

Racial and ethnic minority groups, as well as gender minorities seeking gender-affirming care and surgery have historically had difficulties with healthcare access and experience. The intersection of these two groups may result in deficient healthcare for patients of minority racial and ethnic groups seeking gender-affirming surgery. The present study sought to explore differences in gender-affirming genital surgery experience by race. The 2018-2021 Healthcare Utilization Project National Inpatient Survey was queried for gender-affirming surgeries. Demographic, inpatient safety, and hospital-level characteristics were collected. Results were stratified by race and evaluated for significant differences. A total of 4,605 patients were included in the study, 3,345 patients were identified as White (73%), 320 as Black/African American (7%), 485 as Hispanic/Latino (11%), and 110 as Asian/Pacific Islander (2%). Black/African American patients experienced a higher rate of inpatient medical complications than the overall population (1% vs. 3%, P=0.004) and had a longer length of stay (3 vs. 5 days, P<0.001). The highest total charges were observed among Black/African American patients ($130,873, IQR $119,235, P<0.001). Black/African American patients also less often experienced routine discharge (94% vs. 81%, P<0.001) and more often required a higher level of care upon discharge, such as home health care or transfer to another facility (6% vs. 17%, P<0.001). While the healthcare population is becoming more diverse, healthcare disparities still exist among non-White individuals receiving gender-affirming genital surgery. The present data suggest that Black/African American patients receiving gender-affirming genital surgery have more complicated hospital and discharge courses, and experience higher total hospital charges.

Racial and Ethnic Disparities in Neonatal Sepsis.

Sepsis is a significant health burden in the neonatal population. Although disparities in neonatal care have been reported, there are no data on racial/ethnic disparities in the context of sepsis. Therefore, we aimed to assess racial/ethnic disparities in the prevalence and outcomes of neonatal sepsis. The national inpatient Kids' Inpatient Database produced by the Healthcare Cost and Utilization Project was used for the year 2019. The International Classification of Diseases, 10th revision codes were used to identify the primary outcome of the neonates diagnosed with sepsis. The χ2 and Fisher tests were used to calculate odds ratios for categorical variables, and logistic regression was performed to calculate adjusted odds ratio (aOR) to account for confounders in neonatal sepsis. Of the total 3,512,817 patients, 202,103 patients with neonatal sepsis were identified across all racial and ethnic groups. Overall prevalence was statistically significant in Black [aOR, 1.13 (95% confidence interval [CI], 1.10-1.17)], Hispanic [aOR, 1.19 (95% CI, 1.15-1.22)], Asian/Pacific Islander [aOR, 1.10 (95% CI, 1.05-1.16)] and Native Americans [aOR, 1.17 (95% CI, 1.04-1.31)] compared with Whites. In Black infants, the OR for the overall mortality was 1.35 (95% CI, 1.28-1.42), and sepsis-related mortality was 1.20 (95% CI, 1.06-1.35) compared to Whites. Although the prevalence of sepsis is marginally higher in Hispanic infants compared with Whites, the overall and sepsis-related mortalities are the highest in Black infants compared with all races and ethnic groups.

Predictors of Psychiatric Hospitalization After Discharge From Inpatient Neurorehabilitation for Traumatic Brain Injury.

To examine, among persons discharged from inpatient rehabilitation for traumatic brain injury (TBI), the degree to which pre-TBI factors were associated with post-TBI hospitalization for psychiatric reasons. The authors hypothesized that pre-TBI psychiatric hospitalization and other pre-TBI mental health treatment would predict post-TBI psychiatric hospitalization following rehabilitation discharge, up to 5years post-TBI. Five Veterans Affairs Polytrauma Rehabilitation Centers. Participants with nonmissing rehospitalization status and reason, who were followed at 1 year (N=1006), 2years (N =985), and 5years (N =772) post-TBI. A secondary analysis of the Veterans Affairs TBI Model Systems, a multicenter, longitudinal study of veterans and active-duty service members with a history of mild, moderate, or severe TBI previously admitted to comprehensive inpatient medical rehabilitation. This study examined participants cross-sectionally at 3 follow-up timepoints. Psychiatric Rehospitalization was classified according to Healthcare Cost and Utilization Project multilevel Clinical Classifications diagnosis terminology (Category 5). Rates of post-TBI psychiatric hospitalization at years 1, 2, and 5 were 4.3%, 4.7%, and 4.1%, respectively. While bivariate comparisons identified pre-TBI psychiatric hospitalization and pre-TBI mental health treatment as factors associated with psychiatric rehospitalization after TBI across all postinjury timepoints, these factors were statistically nonsignificant when examined in a multivariate model across all timepoints. In the multivariable analysis, pre-TBI psychiatric hospitalization was significantly associated with increased odds of post-TBI psychiatric hospitalization only at 1-year post-TBI (adjusted odds ratio=2.65; 95% confidence interval, 1.07-6.55, P =.04). Posttraumatic amnesia duration was unrelated to psychiatric rehospitalization. Study findings suggest the limited utility of age, education, and pre-TBI substance use and mental health utilization in predicting post-TBI psychiatric hospitalization. Temporally closer social and behavior factors, particularly those that are potentially modifiable, should be considered in future research.

Role of Hospital Connectedness in Brain Metastasis Outcomes

Although patients with brain metastases receive interdisciplinary and multi-institutional care, the association between neuro-oncologic care networks and patient outcomes remains unknown. As patients often interact with multiple facilities, quantifying this association across a network of hospitals is critical to capture the complexity of the health care journey for patients with brain metastases. To evaluate how statewide health care network metrics are associated with inpatient mortality and hospital length of stay (LOS) for patients with brain metastases. This multicenter, statewide cohort study used data from the 2018 to 2019 Healthcare Cost and Utilization Project State Inpatient and Emergency Department Databases. Primary analyses were completed by August 2023. Participants included adults with a brain metastases receiving care in Massachusetts. All inpatient and emergency department visits mapped for patients following the first diagnosis of brain metastasis. Inpatient mortality and hospital LOS were the main outcomes assessed. Hospital interdependence in brain metastases care was calculated using a connectedness score (weighted degree: weighted sum of ties to other care facilities). The association between hospital connectedness and clinical outcomes was analyzed using mixed-effects logistic and linear regression models, adjusting for hospital-level features. In this cohort study, 4679 patients with brain metastases were identified with inpatient or ED encounters in Massachusetts (from 2018 to 2019). The median (IQR) age was 64 (57-73) years, and 2559 (55%) were female. There was interdependence in brain metastases care, with 993 patients (21%) visiting 2 or more unique hospitals. Highly connected hospitals were heterogeneous, with many being small and one-half lacking subspecialty neuro-oncologic care or teaching status. Increased hospital connectedness was significantly associated with improved inpatient mortality for patients with brain metastases, with the lowest connectedness quartile associated with more than double the risk of mortality compared with the highest quartile (odds ratio, 2.34; 95% CI, 1.33-4.11; P = .003). A stepwise increase in inpatient mortality risk was observed as hospital connectedness decreased, independently of hospital volume. Furthermore, intermediate hospital connectedness was associated with increased hospital LOS (coefficient, 1.08; 95% CI, 0.17-1.95; P = .006). This study found that hospital-to-hospital interconnectedness was significantly associated with improved clinical outcomes for patients with brain metastases. The salience of network metrics highlights their potential role alongside other patient-level and hospital-level variables to evaluate and improve oncology care delivery.

Abstract A006: Disparities, social determinants of health, and ovarian cancer: predicting ovarian cancer using sociodemographic information and comorbidities as risk factors

Abstract Introduction In this study, we aimed to identify associations between ovarian cancer (OC) and patient information, including demographics and comorbidities in order to increase awareness of OC risk factors and the ways in which disparities affect individual risk. Methods Administrative data analysis was performed using Florida state inpatient data collected by the Healthcare Cost and Utilization Project in 2012. Demographic variables included age, race, insurance type, and income level. Comorbidities included hypothyroidism, diabetes, hysterectomy, obesity, alcohol abuse, and drug abuse. For each variable, descriptive and logistic regression analyses were performed using SAS software and confirmed with SPSS software to determine frequencies within binary OC outcomes and calculate associations. Results Descriptive analysis revealed that OC was most frequent in white women (73.47%) over 65 (50.17%), who were Medicare beneficiaries (57.00%) within the second quartile of annual income ($38,000-$48,000) (30.71%). Most OC patients did not have any comorbidities. Logistic regression analysis revealed higher risk of OC in women over 65 compared to younger women (OR= 4.277; 95% CI= 3.585-5.103). Black women had reduced odds of OC compared to White women (OR=0.790; 95% CI= 0.693-0.900). Privately insured women had higher odds of OC compared to women with Medicare (OR= 1.426; 95% CI= 1.245-1.634). The risk of OC was reduced in patients in the first, second, and third quartiles of annual income when compared to the highest quartile of annual income (OR= 0.606; 95% CI= 0.527-0.698, OR= 0.618; 95% CI= 0.537-0.710, OR= 0.644; 95% CI= 0.557-0.743, respectively). The risk of OC was increased in women with hypothyroidism (OR= 1.083; 95% CI= 1.021-1.148), diabetes (OR= 1.134; 95% CI= 0.973-1.331), and women who had a hysterectomy (OR= 18.543; 95% CI= 15.262-22.530), compared to those without. Odds of OC were significantly reduced in women with obesity (OR= 0.574; 95% CI= 0.503-0.654) compared to those without. Women who abused alcohol or drugs had lower odds of OC than those who did not (OR= 0.296; 95% CI= 0.205-0.426, OR= 0.280; 95% CI= 0.205-0.382, respectively). Conclusions This study identifies OC risk factors and highlights differences in the prevalence and risk of OC between women of different sociodemographic groups and between women with and without various comorbidities. Groups with socioeconomic privilege were at higher risk of OC. Financial stability and access to healthcare increase the likelihood of receiving a diagnosis, suggesting potential detection bias. Decreased risk of OC was observed in patients with stigmatized comorbidities such as obesity and substance abuse disorders. Under-investigation of symptoms is common in patients with these conditions, leading to underdiagnosis. Health and socioeconomics are inextricable, so it is necessary to understand the relationship between these aspects of patient health and OC to more accurately assess individual risk.

Language-Based Disparities in Route of Hysterectomy for Benign Disease

Study ObjectiveTo assess the association between patient primary language and route of hysterectomy. DesignA retrospective cohort study was conducted using the Healthcare Cost and Utilization Project's State Inpatient Database (SID) and State Ambulatory Surgery and Services Database (SASD). SettingAll inpatient and outpatient hysterectomies from the most recent year of available data (2020–2021) from the six states that record patient primary language in the SID and SASD (Indiana, Iowa, Maryland, Michigan, Minnesota, and New Jersey) were queried. Patients or ParticipantsPatients aged 18 and over undergoing an inpatient or ambulatory hysterectomy for benign indication. InterventionsMinimally invasive hysterectomy compared to abdominal hysterectomy. Measurement and Main ResultsThe association between patient primary language (English vs. non-English) and route of hysterectomy (abdominal vs minimally invasive) was evaluated. The cohort included 52,226 patients who met inclusion criteria. The majority of patients were non-Hispanic White (71%), with a median age of 46 years (IQR 40.0–53.0). 91.4% of patients spoke English as their primary language, 3.6% spoke Spanish, and 5.0% spoke another non-English language. Patients with a non-English primary language were significantly less likely to undergo minimally invasive hysterectomy compared to patients who spoke English (OR 0.60, 95% CI 0.56–0.64, p <.001). This association remained significant following adjustments for age, race, insurance, median income, state, and fibroid, abnormal uterine bleeding, prolapse or endometriosis diagnosis (aOR 0.77, 95% CI 0.71–0.84). In a sensitivity analysis of English vs Spanish vs other non-English language, the association remained significant for other non-English languages (aOR 0.67, 95% CI 0.60–0.75) but not for Spanish (aOR 0.95, 95% CI 0.83–1.09). ConclusionPatients who are non-English speaking are significantly less likely to receive a minimally invasive hysterectomy. Addressing language disparities may improve access to a minimally invasive route of surgery, a possible surrogate for improved surgical outcomes, for our gynecologic patients.

Unplanned hospital readmission after cholecystectomy in adults with cerebral palsy.

Adults with cerebral palsy (CP) are a largely understudied, growing population with unique health care requirements. We sought to establish a deeper understanding of the surgical risk in adults with CP undergoing a common general surgical procedure: cholecystectomy. Data were obtained from the State Inpatient Database developed for the Healthcare Cost and Utilization Project. Inclusion criteria included patients ≥ 18years with CP and a primary ICD-9 procedure code indicating open or laparoscopic cholecystectomy. Demographics, procedure-related factors, and comorbid conditions were analyzed, and unplanned 30 and 90day readmission rates calculated for each variable. Reasons for readmission based on ICD-9 diagnosis codes were grouped into relevant categories. Univariate analysis identified factors significantly associated with readmission rates. A total of 802 patients with CP met the inclusion criteria. Unplanned 30 and 90day readmission rates after laparoscopic cholecystectomy were 11.4% and 18.1%, respectively. Average length of stay (LOS) after laparoscopic cholecystectomy was 7.1days. After open cholecystectomy, 30 and 90day readmission rates were 16.9% and 30.3% with an average LOS of 14.6days. Infection was the most common cause for 30 and 90day readmission. Factors associated with 30day readmission included type of cholecystectomy, LOS, discharge to skilled nursing facility, and comorbid diabetes and malnutrition. Factors associated with 90day readmission included type of cholecystectomy, LOS, discharge to skilled nursing facility, and comorbid heart failure, renal disease, epilepsy, and malnutrition. Unplanned readmission rates after open and laparoscopic cholecystectomy in adult patients with CP are much higher than previously demonstrated rates in the general population. These patients frequently suffer multiple comorbid conditions that significantly complicate their surgical care. As more and more of these patients live longer into adulthood, further study is warranted to grasp the perioperative risk of simple and complex surgical procedures.

Incidence of deep vein thrombosis and pulmonary embolism in closed foot and ankle fractures treated with conservative versus surgical management: A nationwide analysis

ObjectivesThough there is extensive research on recovery and outcomes of proximal joint fractures, such as hip and knee, there is a paucity of such research in foot and ankle fractures and a lack of uniform data on the incidence of venous thromboembolism (VTE). This is a retrospective cohort study that seeks to investigate the incidence of VTE following surgically versus conservatively treated foot and ankle fractures MethodsThis study included all adult-patient hospitalizations with International Classification of Disease 10th Revision diagnosis codes related to closed foot and ankle fractures as a primary diagnosis in the National Inpatient Sample, an administrative database part of the Healthcare Cost and Utilization Project, for a total of 209,595 cases. Multivariate binary logistic regression was performed to determine the effect of age, gender, past medical history of venous thromboembolism (PMHVTE), Charlson Comorbidity Index, race, surgery, and transfusion of red cell products on the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE). ResultsOur study found an overall incidence of DVT and PE to be 0.4 % and 0.3 %, respectively, following foot or ankle fracture. Conservative management was found to have an increased relative risk of DVT and PE of 2.02 and 1.15, respectively. This difference persisted on performing inverse probability treatment weighting (IPTW) analysis to account for confounders. PMHVTE and requirement of blood transfusion was associated with an increased odds ratio (OR) of 3.41 and 3.217, respectively. Cases identified as Black and Asian/Pacific Islander also had an increased OR of DVT. ConclusionsThe results of this study demonstrate that surgical management of foot and ankle fractures is associated with a lower relative risk of VTE compared to medical management. PMHVTE and transfusion of red cell products increase the odds of VTE following either form of intervention.

Interatrial Wall Abnormality is Associated with Adverse Same-Admission Outcomes Following Total Knee Arthroplasty.

Total knee arthroplasty (TKA) is the most common joint arthroplasty procedure and is shown to be a reliable and efficacious way to improve quality of life. Individuals with interatrial wall abnormalities (IAWAs), such as atrial septal defect or patent foramen ovale (PFO), are at increased baseline risk for stroke and overall lifetime morbidity. The purpose of our study was to elucidate the association between IAWAs and perioperative TKA outcomes.We performed a retrospective cohort study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample database. Admissions for TKA between 2010 and 2019 were identified using the international classification of disease (ICD)-9 and ICD-10 procedure codes. Patients with ICD-9-clinical modification (CM) diagnosis code 7455 or ICD-10-CM diagnosis code Q211 were assigned to the IAWA cohort, the primary exposure. Confounding variables included basic demographics, baseline health status, and surgical facility characteristics. The primary outcomes studied were medical complications, implant-related complications, and admission mortality. Univariate and adjusted multivariable regression analyses were used to identify associations.Compared to patients in the non-IAWA cohort, those in the IAWA cohort had significant risks for same-admission medical complications (odds ratio [OR] 5.77, 95% confidence interval [CI] 4.59-7.15; p < 0.001), implant-related complications (OR 1.55, 95% CI 1.09-2.12; p = 0.009), stroke (OR 77.46, 95% CI 58.4-101.2; p < 0.001), venous thromboembolism (VTE; OR 3.78 95% CI 2.47-5.51; p < 0.001), and mortality (OR 8.36, 95% CI 3.54-16.52; p < 0.001) following TKA.Compared to patients without IAWAs, those with IAWAs who undergo TKA have higher risks for same-admission medical and implant-related complications as well as same-admission mortality. Similarly, these patients have higher risks for same-admission stroke and VTE. Further research on perioperative TKA management in patients with IAWAs is needed.Level of Evidence is III: retrospective cohort study.

Severe Maternal Morbidity by Disability Status and Type in the United States

OBJECTIVE: To estimate the risk of severe maternal morbidity (SMM) among women with disabilities compared with those without disabilities in a nationally representative sample of U.S. delivery hospitalizations. METHODS: We conducted a retrospective cohort analysis using the 2016–2021 Healthcare Cost and Utilization Project's Nationwide Inpatient Sample. We identified delivery hospitalizations and disability status using International Classification of Diseases, Tenth Revision diagnosis codes. The primary outcome was SMM, which was determined using 21 indicators specified by the Centers for Disease Control and Prevention. We used Poisson regression to estimate unadjusted and adjusted relative risks (aRRs) and 95% CIs for the association between disability status and type with SMM outcomes. RESULTS: Among 4,331,457 delivery hospitalizations, 128,413 (3.0%) were to women with disabilities. Women with disabilities had significantly higher rates of SMM compared with those without disabilities (396/10,000 deliveries vs 177/10,000 deliveries). In fully adjusted models, women with disabilities had an aRR of 1.86 (95% CI, 1.80–1.91) for one or more SMM indicators. The risk of SMM varied by disability type, with the highest risks observed for women who had vision disabilities (aRR 3.02, 95% CI, 2.70–3.38) or had physical disabilities (aRR 2.44, 95% CI, 2.34–2.55). Women with disabilities had the highest risk for other medical complications (puerperal cerebrovascular disorders and sickle cell disease with crisis), followed by other obstetric complications, respiratory complications, cardiovascular complications, acute renal failure, sepsis, and bleeding complications compared with women without disabilities. CONCLUSION: Women with disabilities have a significantly higher risk of SMM during delivery compared with those without disabilities, with the magnitude of risk varying by disability type. Efforts to reduce SMM and maternal mortality in the United States must prioritize the unique needs of this population and ensure equitable, disability-competent care for all women.
