Abstract 4138570: The Hidden Killer in Patients with Sepsis Spectra Disorders: Systolic Heart Failure

Introduction: Sepsis and systolic heart failure (sHF) often prompt hospitalization and require near diametrically opposite treatment strategies. We, therefore, studied whether sHF would impact outcomes in patients with sepsis spectra. Methods: We examined the National Inpatient Sample 2021 for adults admitted with sepsis spectra (sepsis, severe sepsis, and septic shock). We compared patients with sHF vs those without. STATA 18 th edition was used for analyses. Age, gender, race, hypertension, diabetes, obesity, dyslipidemia, and Elixhauser comorbidity index were identified as confounders by univariate analyses and tested further with multivariate logistic regression models. The primary outcome was mortality. Secondary outcomes were the need for intubation, cardiac arrest, length of stay (LOS), and total hospital charges. Results: In 2021, nationwide, 3,030,351 adults were admitted for sepsis spectra, and 209,134 (6.9%) had concomitant sHF. Patients with sHF and sepsis spectra (as compared to those without sHF) were less likely female (35.5% vs. 48%), had a substantially higher likelihood of a prior MI, and nearly 50% were diabetic and hyperlipidemic with a higher comorbidity index. Baseline characteristics are in the Table. Sepsis and sHF resulted in substantially higher mortality (22.7%) as compared to patients with sepsis alone (14.9%) adjusted odds ratio (aOR) of 1.11 (CI 1.08-1.14; p-value < 0.001). Patients with sepsis and sHF were more likely to require intubation 22.2% vs. 14.0% aOR 1.21 (CI 1.18-1.25; p-value < 0.001), had more cardiac arrest 7.7% vs. 4.0% aOR 1.38 (CI 1.32-1.44; p-value < 0.001), and a longer LOS (11.9 vs 9.4 days adjusted incidence rate ratio (aIRR) 1.06; CI 1.05 – 1.08; p-value < 0.001). Consequently, total hospital charges were also higher, $189,415 vs $133,720, aIRR 1.15 (CI 1.13-1.18; p-value < 0.001). Conclusion: In 2021, nationwide, sepsis spectra remain a major cause of in-patient mortality. We demonstrate that the coexistence of systolic heart failure and sepsis dramatically worsens complications, mortality, and total hospital costs. This study is a call to action for the in-depth analyses of this very high-risk group of patients.

Abstract 4144525: An Observation Of Racial Disparities In Patients Admitted With St Segment Elevated Myocardial Elevation

introduction: This sudy explores the multifaceted nature of racial disparities among patients admitted with STEMI, shedding light on the complex interplay of social, economic, and healthcare factors that contribute to differential outcomes among diverse populations. Methods: we examined the national inpatient sample 2017-2020 for adult admitted with st segment myocardial infarction,we compared the clincal outcome based on racial distribution.STATA 18th edition was used for analyses. Age, gender, race, hypertension, diabetes, obesity, dyslipidemia, and Elixhauser comorbidity index were identified as confounders by univariate analyses and tested further with multivariate logistic regression models. The primary outcome was mortality. Secondary outcomes were the need for intubation, cardiac arrest, length of stay (LOS), and total hospital charges. Results: There were 826315 hospitalizations with STEMI. Mean age was 64 yrs and 62% were male. Among the admitted patients, Caucasians were 593575 (72%), Blacks were 75025(9.1%),Hispanics were 69605(8.4%), Asians were 23734(2.9%). All-cause mortality in patients admitted with STEMI was 88125 where subgroup Analysis with Caucasians, Blacks ,Hispanics and Asians had 60074(10.1%) vs 9135 (12.1%) vs 7645(10.9%) and 2999(12.6%) respectively. Further subgroups analysis revealed that Blacks (13.9%, aOR 1.37 CI 1.28-1.47,P value<0.001) were more likely to require intubation,followed by Asians(13.5% aOR 1.59 CI 1.43--1.76, p value <0.001) ,then Hispanic (13% aOR 1.45,CI 1.35-1.56 P vale <0.001)and caucasians were least likely to require intubation(9.7% ) Finally, racial subgroup showed significant primary andsecondary outcomes that are presented in Table 1. Conclusion: All obtained results revealed statistical significance and we considered Caucasian population as baseline. Mortality waa highest amongst Asians,followed by Blacks then Hispanics and least in the caucasian subgroup. Understanding these disparities is essential for improving healthcare equity and ensuring that all patients receive appropriate and equitable care regardless of their racial or ethnic background.

Abstract 4135273: Frailty increases the risk of in-hospital mortality and post-procedural complications in patients undergoing Cardiac Implantable Electronic Devices placement

Background: Heart failure with reduced ejection fraction (HFrEF) often necessitates the use of cardiac implantable electronic devices (CIED) such as cardiac resynchronization therapy defibrillators (CRT-D) or implantable cardioverter-defibrillators (ICD). These devices are proven to reduce mortality, prevent hospitalizations, and improve symptoms and quality of life. Frailty, characterized by an age-associated decline in physiological reserve, significantly impacts outcomes in these patients. This study uses the Hospital Frailty Risk Score (HFRS) to assess the effect of frailty on mortality and post-procedural complications in HFrEF patients undergoing CIED implantation. Hypothesis: Frail patients with HFrEF have worse in-hospital outcomes after CIED placement Methods: We conducted a retrospective cohort study using the 2020 National Inpatient Sample database from the Healthcare Utilization Project. Our population included patients aged 18 years or older with HFrEF who underwent CRT-D or ICD placement, identified using ICD-10 procedure codes. The primary risk factor was frailty, classified by an HFRS score of ≥5 (frail) or <5 (not frail). The primary outcome was in-hospital mortality, and the secondary outcome was the composite of post-procedural complications. Multivariate regression analysis was used to estimate the odds ratio. Results: Out of 24,809 patients who underwent ICD or CRT-D placement, 48.8% were frail. Non-Frail patients had lower mean age compared to Frail patients (66.2 vs 67.3 years old, p=0.003). In-hospital mortality was 1.1%, and 7% experienced post-procedural complications. In-hospital mortality was higher in frail patients compared to non-frail patients (2% vs 0.3%, p<0.001). In the multivariate analysis, frail patients had higher odds of in-hospital mortality compared to the non-frail group subset (OR=5.97; 95% CI: 2.77-12.88, p<0.001). Additionally, frailty was associated with higher odds of post-procedural complications (OR=1.28; 95% CI: 1.01-1.63, p<0.001), increased length of stay (5 vs 11.6 days, p<0.001), and total hospital charges (215,668 vs 324,474 , p<0.001). Conclusion: Frailty significantly increases the risk of in-hospital mortality and post-procedural complications in HFrEF patients. This highlights the importance of considering frailty as part of a pre-procedural risk stratification assessment and tailoring management strategies to improve outcomes for these high-risk patients.

Abstract 4130368: Outcomes of Patients with Critical Limb Ischemia and Chronic Kidney Disease: A National Perspective

Background: Studies exploring the relationship between peripheral arterial disease (PAD), critical limb ischemia (CLI), and chronic kidney disease (CKD) and its effect on in-hospital outcomes are limited. Objectives: We aimed to analyze the outcomes of patients with CKD and PAD who are admitted for CLI. Methods: We utilized the National Inpatient Sample (NIS) to capture hospitalizations for CLI from 2016-2020 and then identified cases with concomitant CKD. The primary outcome was mortality, and secondary outcomes were cerebrovascular accident, major bleeding, vasopressor requirement, percutaneous coronary intervention, cardiac arrest, acute respiratory failure, transfusion, length of stay (LOS), and total hospital charges. Multivariable logistic regression was performed to adjust for covariates. Results: A total of 441,245 patients with CLI were identified, of which 122,370 (27.7%) reported concomitant CKD. Patients with CKD had a higher in-patient mortality (OR 1.68, CI, 1.17-1.68, p < 0.001), vascular complications (OR 1.31, 95% CI, 1.17-1.48, p<0.001), acute kidney injury requiring hemodialysis (OR 3.17, 95% CI, 2.64-3.80, p< 0.001) and major bleeding (OR 1.12, 95% CI 1.05-1.19, p<0.001). Patients with CKD underwent conservative (31.08% vs 36.73%, p<0.0001) and invasive procedures (14.73% vs 23.55%, p<0.0001) less often. PAD-CLI with CKD was associated with major (20.54% vs. 16.17%, OR 1.04; p<0.0001) and minor (26.87% vs. 19.53%, OR 1.2, p<0.0001) amputations more often. Conclusion: Patients admitted for PAD-CLI with concomitant CKD have significantly higher in-hospital mortality as compared to patients without CKD. Moreover, patients with CKD and PAD-CLI are less likely to receive revascularization and more likely to undergo amputation

Abstract 4138475: Comparative Outcomes of Transcatheter Aortic Valve Implantation and Surgical Aortic Valve Replacement in Patients with Right Heart Failure: Insights from Nationwide Readmission Database

Background: The annual number of transcatheter aortic valve implantation (TAVI) performed has surpassed that of surgical aortic valve replacement (SAVR) as its use expands to patient populations not included in initial clinical trials. However, in patients with Right Heart Failure (RHF), the outcomes of TAVI and SAVR remain unclear. Methods: We conducted a retrospective cohort study using the Nationwide Readmission Database from 2018 to 2021. Using ICD-10 codes, we identified all adult admissions for TAVI and SAVR with the presence of RHF. The primary outcome was in-hospital mortality. Secondary outcomes included in-hospital complications, 30-day readmission rate, length of stay, and total hospitalization charges. Results: The study included 3,712 adult patients with RHF, of which 1,386 (37.3%) underwent TAVI and 2,326 (62.7%) underwent SAVR. Compared to SAVR patients, TAVI patients were older (63 years vs. 76 years, p<0.01) and had a higher burden of peripheral vascular disease, chronic liver disease, and coagulopathy, while SAVR patients had a higher burden of hypertension, diabetes mellitus, coronary artery disease, left heart failure, chronic lung disease, smoking, malignancy, and anemia. On multivariable analysis, compared to TAVI, SAVR was associated with higher odds of mortality (26.6% vs. 9.3%, p<0.01), mechanical circulatory support use (41.5% vs. 9.22%, p<0.01), respiratory failure (34.2% vs. 10.2%, p<0.01), acute kidney injury (58.1% vs. 37.7%, p<0.01), and need for blood transfusion (31.4% vs. 11.0%, p<0.01). There was no difference in 30-day readmission (13.8% vs. 14.3%, p=0.51) and permanent pacemaker implantation (7.0% vs. 8.7%, p=0.33). SAVR was associated with a longer median hospital stay (14 days vs. 8 days, p<0.01) and higher hospitalization charges ($406,826 vs $265,303, p<0.01). When compared to patients wihout RHF, the presence of RHF predicted higher in-hospital mortality for both TAVI (9.3% vs. 1.2%, p<0.01) as well as SAVR (26.6% vs. 3.7%, p<0.01). Conclusions: From 2018 to 2021, more RHF patients underwent SAVR (62.7%) than TAVI (37.3%), but SAVR was associated with worse short-term outcomes, including higher in-hospital mortality, in-hospital complications, and healthcare resource utilization.

Abstract 4139144: "Comparative Analysis of Inpatient Outcomes: Decompensated Systolic Heart Failure (HFrEF) with and without Iron Deficiency Anemia, Propensity-Matched Nationwide Study (2017-2021)."

Background: Iron deficiency anemia (IDA) affects approximately one-third of patients with systolic heart failure, yet comprehensive population-based analyses of its impact on in-hospital outcomes remain limited. This study seeks to examine how IDA influences in-hospital outcomes among individuals with decompensated systolic congestive heart failure (HFrEF). Methods: Using data from the National Inpatient Sample (NIS) database spanning from 2017 to 2021, this study identified patients hospitalized for decompensated systolic congestive heart failure (HFrEF) with a secondary diagnosis of IDA using ICD-10 codes such as I5020-23 and D500, D501, D508, D509. Propensity score matching (PSM) was then employed to create cohorts without and with IDA at a 1:3 ratio. Multivariate regression analyses were conducted to evaluate various outcomes, including in-hospital mortality, cardiogenic shock (CS), acute myocardial injury (AMI), cardiac arrest, ventricular tachycardia (VT), ventricular fibrillation (VF), length of stay (LOS), and total hospitalization charges. Furthermore, the utilization rate of mechanical ventilation and circulatory support, including intra-aortic balloon pump and extracorporeal membrane oxygenation, was evaluated in both cohorts. Results: Among 253,034 HFrEF hospitalizations, 16,200 (6.4%) had a secondary diagnosis of IDA. After PSM, multivariate regression analyses revealed no significant differences in the odds of cardiogenic shock (10% vs. 10%, p=0.86), in-hospital mortality (2.6% vs. 2.8%, p=0.71), and LOS (7.19 vs. 7.27 days) between the two groups. Additionally, the likelihood of cardiac arrest, ventricular arrhythmias, AMI, and utilization of mechanical ventilation and circulatory support did not reach statistical significance. However, patients with IDA and HFrEF had higher hospitalization charges ($85,516 vs. $93,000). Conclusion: HFrEF patients, with or without IDA, had similar odds of cardiogenic shock, in-hospital mortality, mechanical circulatory support utilization, as well as LOS. However, IDA with HFrEF correlated with higher hospitalization charges.

Abstract 4145842: The Incidence, Predictors and Impact of 30-day Readmission of Takotsubo Cardiomyopathy Hospitalization: A Retrospective Nationwide Analysis

Objective: This study aimed to describe the recent readmission and mortality rates of unplanned 30-day all cause readmission after takotsubo cardiomyopathy hospitalization. Methods: We conducted an analysis of the 2020 Nationwide Readmission Database. Using the ICD-10 code, we identified hospitalizations for takotsubo cardiomyopathy. We excluded hospitalizations for age<18years and planned or elective readmissions. To compare baseline characteristics between readmissions and index hospitalizations, Pearson χ2 tests were employed. We utilized multivariate Cox regression analyses to identify independent predictors of readmissions. Results: A total of 7554 patients were hospitalized for index admission for takotsubo cardiomyopathy, and 633 of them were readmitted. The 30-day all-cause readmission rate was 8.5% while specific takotsubo readmission rate was 0.4%. The mortality rate in the index admission was 1.9% and 5.5% in readmitted patients. The mean age of index admission was 67.6years vs 70.7 years in readmission, about 89.0% were female in index admission vs 85.0% in readmission cohorts. The most common reasons for readmission were hypertensive heart disease with heart failure, hypertensive heart disease and chronic kidney disease with heart failure, takotsubo syndrome, sepsis, NSTEMI, COPD exacerbation, acute kidney failure, pneumonia, atrial fibrillation. Readmissions had more acute kidney injury (20.6% vs 11.3%, p-value <0.001) and atrial fibrillation (23.0% vs 13.0%, p <0.001) compared to the index admission, however the index admission had more ventricular tachycardia (4.6% versus 1.8%, p=0.02) compared to readmission cohorts. Readmission had longer length of hospital stay (4.9 days vs 3.7 days, p< 0.001), but less mean total hospital charge of (US$51039 vs US$60617, P =0.008). Older age, acute renal failure, pulmonary disease, coronary dissection, longer length of hospital stays and transfer to rehabilitation facility after discharge were identified as statistically significant predictors of readmissions. Conclusion: About one in twelve patients hospitalized with takotsubo cardiomyopathy were readmitted within 30days. Readmissions had a higher mortality rate; acute renal failure, pulmonary disease, coronary dissection were notable reasons for readmission. Understanding the predictors for readmission highlighted in this study would enable clinicians implement preventive strategies to improve the rate of takotsubo cardiomyopathy readmission

Evaluating Outcomes for Women with Metastatic Breast Cancer: Palliative Care Consultations, Hospital Charges, and Length of Stay

Introduction: Women with late-stage metastatic breast cancer are at an increased risk of pain and distress from symptoms and often struggle with associated emotional and financial burden of their disease. Palliative care is known to alleviate symptom burden in patients with end-stage, terminal diseases but is often underutilized in both inpatient and outpatient settings. The current study aims to investigate the prevalence of palliative care consultation on inpatients with metastatic breast cancer and examine the association between palliative care consultation and length of hospital stay and total hospital charges. Methods: Patients diagnosed with metastatic breast cancer between 1998–2017 were abstracted from the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Database (NIS). The primary outcome was the presence of a palliative care consultation (PCC) during the inpatient stay. Secondary outcomes were hospital length of stay and total hospital charges. Multivariable logistic regression was used to examine factors associated with the presence of a PCC. The relationship between PCC and hospital length of stay and total hospital charges were investigated using linear regression. Results: 513,509 cases of metastatic breast cancer were identified, 5.7% had a documented in-hospital palliative care encounter. Of those who received PCC, total hospital charges were about USD 5452 less than those who did not receive consultation. Women who received PCC had higher odds of a longer hospital stay. Predictors of PCC were older age, non-White race, and residing in a lower-income ZIP code. Conclusions: Palliative care remains to be an underutilized resource among patients with end-stage metastatic breast cancer.

Protective effects of long term antiplatelet and anticoagulant therapy in hospitalized patients with inflammatory bowel disease.

Inflammatory bowel disease (IBD), with its rising prevalence rates is associated with an increased risk of cardiovascular and thromboembolic events. Antiplatelets and/or anticoagulants agents are often prescribed but the literature on the impact of long-term anticoagulation and/or antiplatelet use among patients hospitalized with IBD is scarce. The aim of this study is to assess the outcomes of patients hospitalized with IBD on antiplatelet and/or anticoagulant agents. To investigate the effects of long-term use of antiplatelets/anticoagulants on clinical outcomes in patients hospitalized with IBD. We conducted a retrospective cohort study using the Nationwide Inpatient Sample database, including all adult IBD patients hospitalized in the United States from 2016 to 2019. Patient cohorts were stratified based on antiplatelet/anticoagulant therapy status. Multivariate regression analysis was done to assess outcomes, adjusting for potential confounders. The primary outcome was mortality, whereas length of stay (LOS), total parenteral nutrition, acute kidney injury, sepsis, shock, gastrointestinal bleeding, need for colonoscopy/sigmoidoscopy, abdominal surgery and total hospitalization charges were secondary outcomes. Among 374744 hospitalized IBD patients, antiplatelet or anticoagulant therapy alone was associated with significantly lower in-hospital mortality and reduced healthcare utilization, including shorter LOS and decreased hospitalization costs. Combined therapy was associated with a protective effect on mortality, but did not reach statistical significance. Notably, therapy did not exacerbate disease severity or complications, although higher odds of gastrointestinal bleeding were observed. Our study highlights the potential benefits of long-term anticoagulation/antiplatelet therapy in hospitalized IBD patients, with improved mortality outcomes and healthcare utilization. While concerns regarding gastrointestinal bleeding exist, the overall safety profile suggests a role for these agents in mitigating thromboembolic risks without exacerbating disease severity. Further research is needed to look at optimal treatment strategies and addressing limitations to guide clinical decision-making in this population.

The association of obesity and in-hospital outcomes among patients undergoing ablation for atrial fibrillation: a propensity-score matched analysis

Abstract Background Obesity is a strong risk factor for atrial fibrillation (AF), and it can affect the prognosis of AF. However, the impact of obesity (BMI≥30 kg/m²) on postoperative complications after AF ablation has not been extensively studied. We aimed to evaluate the association of obesity with in-hospital outcomes among patients with AF who ablation procedures. Methods The study utilized the National Inpatient Sample (NIS) database 2016-2020. Patients were divided into obese and non-obese groups and matched with propensity score matching (1:1). This matching involved adjusting for baseline variables (including age, gender, primary expected payer, race, and median household income) and comorbidities (including diabetes, hypertension, hyperlipidemia, history of coronary artery bypass grafting (CABG), chronic kidney disease, hyperthyroidism, cardiomyopathy, prior stroke or transient ischemic attack, heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), heart valve disease, coronary artery disease, chronic obstructive pulmonary disease (COPD), alcohol misuse, anemia, and smoking). Furthermore, a weighted analysis was conducted utilizing weights provided by the NIS, and multivariate logistic regression was used to calculate the odds ratio. Results A total of 29,440 patient with AF who underwent ablation were included. After propensity matching, (8,110 in obese and 8,110 in non-obese group) the baseline characteristics were not significantly different between the two groups. Obesity was independently associated with higher risk of pseudoaneurysm, hematoma, postoperative anemia, acute kidney injury, vasopressor need, mechanical ventilation, pulmonary embolism, and ischemic stroke in patients who underwent ablation for AF (Figure 1). In addition, obese group had significantly higher length of stay (median and IQR 2 [1-3] vs 2 [1-4]) and total charges (median and IQR: 131,248$ [95,303-197,784] vs 143,693$ [102,720-206728]) compared to non-obese group (p<0.001). However, in-hospital mortality was not significantly different between the two groups. Conclusion In patients who underwent AF ablation, obesity is associated with significantly higher risk of post-operative complications, as well as increased LOS and total hospital charges.

The effect of HIV seropositivity on inpatient outcomes in atrial tachyarrhythmias: a US population analysis

Abstract Background With the advent of antiretroviral therapy, the life expectancy of persons living with HIV(PLHIV) has been significantly prolonged and we are now seeing this group increasingly affected by chronic conditions. Atrial fibrillation is the most common sustained tachyarrhythmias in adults and commonly coexists with atrial flutter. HIV-1 especially has been shown to possess a specific cardiac tropism in which chronic immune activation and inflammation may lead to cytotoxicity and death of cardiac myocytes. It has also been associated with left atrial enlargement, which may increase arrhythmia generation and propagation. The effect of HIV on outcomes in atrial tachyarrhythmias have been poorly studied, so we therefore wanted to explore this influence on in-patient outcomes. Purpose To assess the effect of HIV seropositivity on inhospital outcomes of patients admitted with atrial fibrillation/flutter (AF) Method The study uses data from the HCUP-NIS database, which includes billing information from hospitals across the US. The study population included patients admitted with a principal diagnosis of atrial fibrillation or atrial flutter in 2020. Patients with HIV positivity were identified using ICD-10 codes. Multivariate regression was used to analyze outcomes while adjusting for confounders. They were classified into two groups: AF-only (AF-O) and AF with HIV (AF-H). Results A total of 400,715 patients were admitted with a primary diagnosis of atrial fibrillation/flutter in 2020, 1175 were PLHIV. Patients in the AF-H group were more likely to be younger, non-Caucasian, tobacco smokers, have lower median income, be uninsured, have HFrEF and CKD. They however had lower rates of HFpEF than persons in the AF-O group. After adjusting for hospital level confounders, the in-hospital mortality rate was similar between the two groups (aOR 0.46 95% CI 0.05-3.98, p=0.48). The rates of ischemic stroke/systemic embolization, major bleeding, in hospital respiratory failure, length of stay and total hospital charges were also not significantly different Conclusion The study suggests that AF patients with HIV have similar in-hospital mortality rates as patients without. There are significant differences in the economic and ethnic makeup of the two groups but these did not significantly influence the outcomes of interest. Larger cohorts will be needed to confirm these findings definitively, especially as more persons with HIV continue surviving past the sixth decade of life.

Impact of household income on acute decompensated heart failure outcomes: national representative sample

Abstract Background The clinical outcomes of ADHF have been extensively studied; however, the impact of household income still needs to be better understood. This study aimed to elucidate the relationship between household income and outcomes in patients with ADHF. Methods This national retrospective cohort study used data from the 2016-2020 National Inpatient Database, focusing on patients admitted with ADHF. We stratified the cohort into two groups based on the median household income: below $50k and above $86k. The selection criteria included patients aged ≥ 18 years diagnosed with ADHF, excluding those with incomplete income data. The primary outcome was all-cause inpatient mortality, with a length of stay (LOS) and total hospital charges as secondary outcomes. Statistical analysis employed logistic and linear regressions adjusted for confounders, with the significance level set at p<0.05. We accounted for missing data using multiple imputation analyses. Results 1,123,024 patients admitted with ADHF met the inclusion criteria. We divided the groups into two cohorts: low-income (64%, N=718,735) and high-income (36%, N=404,289). No increase in mortality was identified (adjusted aOR: 1.05; p = 0.212). The study revealed that high-income patients had marginally longer average LOS (5.62 days vs. 5.35 days, p < 0.0001) and higher hospital charges ($62,512.46 vs. $49,440.14, p < 0.0001) compared to their low-income counterparts. Low-income patients exhibited a higher prevalence of hypertension and obesity, whereas high-income individuals were more affected by atrial fibrillation and hyperlipidemia (hypertension and obesity, p < 0.0001; atrial fibrillation, p < 0.0001). Conclusion In this national retrospective cohort of patients admitted for ADHF over five years, income did not affect mortality. However, LOS and total charges were affected by the median household income.

30-Day Readmissions and the Need for Emergency Surgery Following Non-Operative Management of Perforated Diverticulitis.

Background: Limited data are available on the evaluation and outcomes of patients with perforated diverticulitis who were treated without surgery. Aims: This retrospective review was aimed at investigating the 30-day non-elective re-admission rates for patients hospitalized with perforated diverticular disease who were treated without surgery, rates of patients requiring surgery on re-admission, and the independent predictors of re-admission. Methods: A total of 143,546 patients from the National Readmission Database, between 2016 and 2020, who were admitted with perforated diverticulitis and treated non-operatively were reviewed. Re-admitted patients were compared with those not re-admitted. Comparisons for continuous and categoric variables were made using the student t-test and chi-squared test, respectively. A logistic regression model was used to determine independent factors associated with re-admission. All analyses were done with SAS 9.4; p values <0.05 identified significance. Results: Among patients with perforated diverticulitis who were treated non-operatively, 17,868 (12.4%) were re-admitted within 30 days and 4,924 (27.6%) of patients re-admitted required surgical intervention. The greatest independent predictors of re-admission include patient insurance status, index length of stay, undergoing a drainage procedure, and patient disposition. Comorbidities predicting re-admission include renal failure, chronic pulmonary disease, diabetes mellitus, fluid and electrolyte disorders, and hypertension. Hospital total charges were greater at the index admission for patients requiring re-admission. Conclusion: Non-operative management of perforated diverticulitis is safe for many patients, but the risks for re-admission and subsequent need for emergency surgery require special consideration.

Preoperative Depression is Associated With a Higher Risk of Bleeding in Type a Aortic Dissection Repair: A Population Study of National Inpatient Sample From 2015-2020.

Depression is highly prevalent in patients with aortic diseases. While depression has been shown to predispose patients to adverse outcomes after surgery, its impact on postoperative outcomes in Stanford Type A Aortic Dissection (TAAD) has not been established. This study aimed to conduct a population-based examination of the effect of preoperative depression on in-hospital outcomes after TAAD using the National/Nationwide Inpatient Sample (NIS) database, the largest all-layer database in the US. Patients undergoing TAAD repair were identified in NIS from the last quarter of 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients with and without preoperative depression, adjusted for demographics, comorbidities, hospital characteristics, primary payer status, and transfer status. There were 321 (7.50%) patients with depression and 3961 (92.50%) non-depressive patients who underwent TAAD repair. Patients with and without depression had comparable in-hospital mortality (11.84% vs 15.37%, P = 0.35). However, Patients with depression had a higher risk of hemorrhage/hematoma (83.49% vs 76.6%, aOR 1.593, 95 CI 1.161-2.184, P < 0.01) and a higher rate of transfer out (40.81% vs 32.62%, aOR 1.396, 95 CI 1.077-1.81, P = 0.01). All other in-hospital complications, hospital length of stay (LOS), and total hospital charge were comparable between patients with and without depression. Preoperative depression is associated with a higher risk of bleeding after TAAD repair. This may be due to anti-depression treatment, such as Selective Serotonin Reuptake Inhibitors (SSRIs), that can disrupt platelet function and lead to abnormal bleeding. While depression is not associated with other major outcomes, preoperative depression screening, as well as hemostatic monitoring and appropriate blood management in patients with depression may be crucial in preventing bleeding complications in TAAD repair.

Impact of Frailty on Early Readmissions of Endoscopic Retrograde Cholangiopancreatography in the United States: Where Do We Stand?

Background/Objectives: We assessed the impact of frailty on outcomes of endoscopic retrograde cholangiopancreatography (ERCP) in the United States. Methods: The National Readmission Database (2016-2020) was used to identify index and 30-day ERCP readmissions, which were categorized into low-frailty, intermediate-frailty, and high-frailty groups based on the Hospital Frailty Risk Score (HFRS). Outcomes were then compared. Results: Of 885,416 index admissions, 9.9% were readmitted within 30 days of ERCP. The odds of 30-day readmission were higher in the intermediate-frailty group (12.59% vs. 8.2%, odds ratio [OR] 1.67, 95% confidence interval [CI] 1.64-1.71, p < 0.001) and the high-frailty group (10.57% vs. 8.2%, OR 1.62, 95% CI 1.52-1.73, p < 0.001) compared to the low-frailty group. On readmission, a higher HFRS also increased mean length of stay (intermediate-frailty vs. low-frailty: 8.49 vs. 4.22 days, mean difference (MD) 4.26, 95% CI 4.19-4.34, p < 0.001; high-frailty vs. low-frailty: 10.9 vs. 4.22 days, MD 10.9 days, 95% CI 10.52-11.28, p < 0.001) and mean total hospitalization charges (intermediate-frailty vs. low-frailty: $118,996 vs. $68,034, MD $50,962, 95% CI 48, 854-53,069, p < 0.001; high-frailty vs. low-frailty: $195,584 vs. $68,034, MD $127,550, 95% CI 120,581-134,519, p < 0.001). The odds of inpatient mortality were also higher for the intermediate-frailty and high-frailty compared to the low-frailty subgroup. Conclusions: Frailty was associated with worse clinical outcomes after ERCP.

Racial/Ethnic Disparities in Hospitalization Outcomes by Palliative Care Utilization and Trends Among Women With Metastatic Breast Cancer in the United States.

We examined the trends in palliative care utilization, racial/ethnic disparities in hospitalization outcomes among adult women with a diagnosis of metastatic breast cancer (MBC), and effect modification by palliative care utilization. Retrospective cohort analyses were conducted using the Agency for Healthcare Research and Quality sponsored Healthcare Cost and Utilization Project-National Inpatient Sample database from 2016 to 2020. Regression analyses were used to evaluate palliative care trends, and the association between race/ethnicity and in-hospital mortality, length of stay, total hospital charges, and discharge disposition. Stratified analyses were conducted by palliative care use. Palliative care consultations in the study population increased from 16.4% in 2016 to 20.3% in 2020. Black (adjusted odds ratio [AOR], 1.25 [95% CI, 1.16 to 1.34]) and Hispanic (AOR, 1.12 [95% CI, 1.01 to 1.23]) female patients with MBC had higher in-hospital mortality compared with the White patients. Among those who received palliative care, Blacks had similar odds (AOR, 1.08 [95% CI, 0.97 to 1.20]) of in-hospital mortality when compared with Whites. Black women were more likely to have longer hospital stays relative to White women. Although Black women had similar odds (AOR, 0.98 [95% CI, 0.92 to 1.04]) of discharge to a short-term/skilled nursing facility versus routine discharge compared with White women, Blacks who received palliative care had 19% (95% CI, 0.70 to 0.95) lower odds of discharge to a facility. Our findings emphasize the importance of palliative care use among patients with MBC and highlight the need to raise awareness of its benefits, especially in minority populations. Further studies are needed to explore ways to narrow the gap in existing disparities and to test these interventions on care metrics and patient outcomes.

Firearm-related Hospitalizations and Newly Acquired Morbidities in Children and Adolescents: A Nationally Representative Study

BackgroundFirearm injury is the leading cause of pediatric death in the United States (US), but few investigations have focused on the healthcare cost and burden of hospitalized survivors. We aimed to delineate the landscape of pediatric firearm hospitalizations, with a focus on sociodemographic characteristics and on acquired morbidity among survivors. MethodsWe performed a retrospective cohort study of hospitalized children (<21 years old) with firearm injuries using the 2019 Kids’ Inpatient Database, representing 80% of pediatric hospitalizations nationally. ResultsThere were 5998 hospitalizations with 5592 hospital survivors, giving a US population-adjusted hospitalization rate of 9.7 per 100,000 subjects <21 years. Black subjects (37.9 per 100,000) were admitted at higher rates than other races and ethnicities (3.8–6.2 per 100,000). Non-survivors were overrepresented in White subjects who were disproportionately victims of suicide. There were 199 new invasive medical devices placed (3.3% of hospitalized subjects), including 194 in 5592 survivors (3.5% of survivors): 87 tracheostomies, 30 feeding tubes, and 77 both. Suicide attempt was overrepresented as a cause of injury in subjects needing new devices. Charges and length of stay were longer for subjects needing new devices. Total charges for all hospitalized subjects exceeded $1.05 billion for 2019, $136 million (13%) of which represented the 3.3% of admissions needing new devices. ConclusionsAmong pediatric firearm hospitalizations in 2019, Black children were overrepresented among assaults, and White children for suicide attempts. Suicide attempts were overrepresented among non-survivors, those requiring new devices, and contributed disproportionately to total hospital charges. Level of EvidenceLevel 3.

7313 Impact of Day of Admission on Hyperosmolar Hyperglycemic State Outcomes- a National Inpatient Sample Study

Abstract Disclosure: B. Neupane: None. S. Karki: None. A. Bhandari: None. K. Rajamani: None. Introduction: Hospital mortality and results are significantly influenced by the day of admission (weekend vs. weekday). Studies have shown there is an increase in rates of adjusted hospital mortality in various diseases. Hyperosmolar hyperglycemic state (HHS), or Hyperosmotic hyperglycemic nonketotic state (HHNK), is a serious complication associated with type 2 diabetes mellitus. There have been limited studies on how the day of admission impacts outcomes in HHS. Objective:To investigate if there are differences in weekend vs. weekday admission with the diagnosis of HHS on hospital outcomes. Methods: Retrospective data on adult patients (age &amp;gt;18) with a primary diagnosis of HHS was taken between 2017 and 2020 using the National Inpatient Sample (NIS). The data analysis tool utilized was STATA. Diseases and outcome codes were selected using the International Classification of Diseases (ICD-10). Multivariate regression analysis was used to adjust for potential variables and determine the adjusted odds ratio (aOR). The Fisher exact test was used to compare proportions, while the student t-test was used to compare continuous variables. The study's primary outcome was mortality; additional secondary outcomes included length of stay (LOS), total hospitalization costs, acute coronary syndrome (ACS), septic shock, pulmonary edema, acute respiratory failure (ARF), mechanical ventilation, acute respiratory distress syndrome (ARDS), acute kidney injury (AKI), and cerebrovascular accidents (CVA). Between 2017 and 2020, the mortality rates, LOS, and total hospitalization charges of weekend and weekday admissions were analyzed. Results:181,720 patients were diagnosed with HHS; 46,100(25.36%) were admitted on the weekend. Weekend admission had increased rates of ARF (aOR =1.2, 11.15% vs. 9.57%, p&amp;lt;0.01) and mechanical ventilation (aOR =1.24, 7.04% vs. 5.79%, p&amp;lt;0.01) compared to the weekday admission. There was no difference in the outcomes of the two groups in the mortality rate, mean LOS, total hospital charges, ACS, septic shock, pulmonary edema, AKI, CVA, and ARDS. In weekend admission, there was an increase in trends of LOS and total hospitalization charges, but there were no significant outcomes in the mortality rates over the years. In weekday admission, there was an increase in mortality rate trends, LOS, and total hospitalization charges. Conclusion: There was an increase in ARF and mechanical ventilation rates on weekends compared to weekday admission. When the two groups were compared, there were no significant outcomes in mortality rate, LOS, hospital charges, and other hospital outcomes. In both weekend and weekday admissions, there was an increase in trends of LOS and total hospitalization charges; however, only admissions during the weekday showed a significant increase in mortality rate trends.

8171 Analysis of Inflammatory Bowel Disease and Hashimoto's Disease: A Nationwide Study

Abstract Disclosure: C. Yang: None. L. Joo: None. B. Blair: None. Analysis of Inflammatory Bowel Disease and Hashimoto’s Disease: A Nationwide Study Introduction: The U.S. population is aging rapidly. There is limited data specifically for patients with Hashimoto’s disease who are older than or equal to 80 years old. We sought to examine the national inpatient sample database to describe in-hospital outcomes among these older patients. Methods: Data were extracted from the National Inpatient Sample (NIS) Database for the years 2019 and 2020. The NIS was searched for hospitalizations of adult patients with Hashimoto's disease using international classification of diseases 10th revision codes. We then examined the outcomes in patients who were older than or equal to 80 years old (YO) vs. younger than 80 years old. Linear regression and multivariate logistic was used accordingly to adjust for confounders. The primary outcome was inpatient mortality. Secondary outcomes were hospital length of stay (LOS), and total hospital charges (TOTHCG). SPSS software was used for statistical analysis. Results: This study included 48,649 patients with Hashimoto’s disease, of which 3,038(6.2%) patients were over or equal to the age of 80. Admissions with Hashimoto’s and old age had higher prevalence of hypertension (12.3% Vs 11.3 %, p&amp;lt;0.001), diabetes mellitus (14.8% VS 11.4% p &amp;lt;0.001), and obesity (6.9% Vs 3.1%, p&amp;lt;0.001). In-hospital mortality was higher among the older cohort (2.6% Vs 0.87, p&amp;lt; 0.001). On linear regression analysis, increased age was associated with increased in-hospital mortality (p&amp;lt;0.001). On multivariable regression, age &amp;gt;80 years was associated with higher odds of inpatient mortality (OR1.229, CI 1.174-1.286, p&amp;lt;0.001)). It was also shown that older Hashimoto’s patients pay significantly more total hospital charges ($82,361vs $70,231) with higher length of stay (7.4 days vs 5.6 days, p&amp;lt;0.001). On secondary analysis, it has shown that Hashimoto’s patients aged more than or equal to 80 years old had higher odds of having Crohn’s Disease (OR 1.032, CI 1.014-1.049, p&amp;lt;0.001) and Ulcerative Colitis (OR 1.025, CI 0.991-1.061, p&amp;lt;0.001). Conclusion: In this nationally representative population-based retrospective cohort study, aging was associated with higher mortality and worse outcomes among patients with Hashimoto’s disease. These results were distinguished in patients with inflammatory bowel disease. Presentation: 6/2/2024

7695 Impact Of Day Of Admission On Outcomes Of Adrenal Insufficiency- A National Inpatient Sample Study

Abstract Disclosure: S. Karki: None. B. Neupane: None. S. Neupane: None. A. Bhandari: None. U. Farooq: None. K. Rajamani: None. Introduction: Admission day (weekend vs. weekday) significantly influences hospital outcomes and mortality in various diseases, with evidence suggesting higher mortality rates associated with weekend admissions. However, the “weekend effect” on adrenal insufficiency remains underexplored in national inpatient samples. Objective of the study:To assess the impact of admission day on mortality rates, hospital stays, costs, and overall outcomes in adrenal insufficiency patients. Methods: A retrospective cohort study encompassing adult patients (age&amp;gt;18 years) was conducted using the National Inpatient Sample (NIS) data spanning from 2017 to 2020. The International Classification of Disease (ICD-10) was used to select codes for diseases and outcomes. STATA was employed for statistical analysis, using multivariate regression analysis to calculate adjusted odds ratios and account for potential confounding variables. Continuous variables were compared using the student t-test, while proportions were compared using the Fisher exact test. The primary outcome was mortality, with secondary outcomes encompassing length of stay (LOS), total hospitalization charges, acute coronary syndrome (ACS), septic shock, pulmonary edema, acute respiratory failure (ARF), mechanical ventilation, acute respiratory distress syndrome (ARDS), acute kidney injury (AKI), and cerebrovascular accidents (CVA). Results: A total of 150,005 patients diagnosed with adrenal insufficiency were included in the analysis. Patients with adrenal insufficiency were categorized into two groups based on the day of admission: weekend and weekday. Weekend admissions constituted 23.5% of the total cases of adrenal insufficiency, with 35,330 patients. Significant differences in outcomes were observed in septic shock (aOR=1.16, 7.24 % vs. 6.30 %, p=0.007), ARF (aOR=1.23, 11.82% vs. 9.87%, p&amp;lt;0.001), mechanical ventilation (aOR=1.35, 6.29% vs. 4.76%, p&amp;lt;0.001), ARDS (aOR=1.83, 0.57% vs. 0.33%, p=0.003), and AKI (aOR=1.15, 24.74% vs. 22.58%, p&amp;lt;0.001) in weekend vs weekday admissions. However, no significant differences were observed in mortality rates, mean length of hospital stay, total hospital costs, ACS, pulmonary edema, and CVA. Conclusion: Weekend admissions for adrenal insufficiency showed poorer outcomes which prompts further investigation into underlying factors. Insights gained might be helpful for strategic planning at state and national levels, aiding in outcome improvement. Presentation: 6/1/2024
