Significant Difference In Inpatient Mortality Research Articles

Abstract P369: Hospital Outcomes of Hypertensive Emergency in Black and White Patients.

Objectives: A rapid and severe increase in blood pressure resulting in new or progressive end-organ damage is defined as a hypertensive emergency. Our study sought to estimate the clinical outcomes of black and white patients admitted for hypertensive emergency. Methods: Using the National Inpatient Sample Database of 2020 (NIS), retrospective data of black and white patients who were admitted for hypertensive emergency were identified using ICD-10 codes. Outcomes were in-hospital mortality, cerebrovascular accident (CVA), acute kidney injury (AKI), myocardial infarction (MI), pulmonary edema, acute hypoxic respiratory failure, length of hospital stay, and total hospital charges. Results: A total of 59690 patients were admitted for hypertensive emergency. 80.6% of patients were either black or white. Black patients were younger (54 years, 95% CI 54 – 55 VS 65 years, 95% CI 65 – 65) when compared to white patients. There were no statistically significant differences in inpatient mortality (p=0.2345), myocardial infarction (p=0.8618), and pulmonary edema (p=0.8835). Black patients had increased acute kidney injury (p<0.0001), acute hypoxic respiratory failure (p=0.0014), length of hospital stays (4 days, 95% CI 4 – 5 VS 3 days, 95% CI 3 – 4), and total hospital charges ($47,132.68, 95% CI $44,808.58 - $49,456.79 VS $43,882.58, 95% CI $42,394.76 - $45,370.39). White patients had increased cerebrovascular accident (p<0.0001) when compared to black patients. Conclusion: Per this study, there was no difference in in-hospital mortality between black and white patients admitted for hypertensive emergency. Black patients had increased AKI, acute hypoxic respiratory failure, length of hospital stays, and charges.

Abstract P370: Dementia Does Not Increase Mortality in Patients Admitted for Hypertensive Emergency.

Objectives: Hypertensive Emergency is an acute, marked elevation in blood pressure that is associated with signs of target-organ damage. We sought to determine the outcome of hypertensive emergency in patients with dementia. Methods: Using the 2020 National Inpatient Sample Database (NIS), we conducted a retrospective analysis of patients admitted for Hypertensive Emergency as a principal diagnosis according to ICD-10 codes. Our primary outcome was inpatient mortality. Secondary outcomes include acute kidney injury (AKI), cerebrovascular accident (CVA), myocardial infarction (MI), acute hypoxic respiratory failure, length of hospital stays, and hospital charges between groups. (Patient with or without Dementia) Results: A total of 59690 patients were admitted for hypertensive emergency. Of those, 4.3% had a history of dementia. Patients with a history of dementia were older (80 years, 95% CI 79 – 81 VS 59 years, 95% CI 58 – 59). There was no statistically significant difference in inpatient mortality (p=0.1363), acute kidney injury (p=0.7461), cerebrovascular accident (p=0.7712), myocardial infarction (p=0.1517), and acute hypoxic respiratory failure (p=0.3088). Patients with dementia had increased length of hospital stays (6 days, 95% CI 5 – 6 VS 4 days, 95% CI 3 – 4) and total hospital charges ($55,302.18, 95 % CI $49,669.87 - $60,934.5 VS $46,685.84, 95% CI $45,231.38 - $48,140.3) Conclusion: This study shows that there is no difference in in-hospital mortality when comparing patients with dementia and the general population admitted for a hypertensive emergency. Patients with dementia had increased length of hospital stays and charges.

Outcome evaluation of pharmacist-physician collaborative protocol-based antimicrobial treatment for hospitalized stroke patients with aspiration pneumonia

ObjectivesTo evaluate the efficacy and patient outcomes of pharmacist-physician collaborative protocol-based antimicrobial treatment regimens for antimicrobial stewardship. MethodsPatients treated for aspiration pneumonia due to stroke within 48 h after admission to Kochi Medical School Hospital (January 2019 to December 2022) were included. Primary outcomes were the cumulative number of days of antimicrobial treatment and length of hospital stay. Secondary outcomes included the percentage of patients under-dosed with first-choice antimicrobial agents and inpatient mortality. ResultsGroup A (66 patients) did not receive the antimicrobial treatment protocol, whereas group B (46 patients) did. There were no differences in the patient backgrounds. Group B had a significantly lower percentage of patients who were undertreated with the first-choice antimicrobial agent (9.1 % vs. 42.9 %). There was no significant difference in inpatient mortality between group A and group B (6.1 % vs. 4.3 %). The cumulative number of days of antimicrobial administration and the length of hospital stay were significantly lower in group B: 7.0 days (95 % CI, 6.0–8.0) vs. 9.0 days (95 % CI, 8.0–11.0) for antimicrobial administration, and 28.5 days (95 % CI, 22.0–35.0) vs. 43.0 days (95 % CI, 28.0–55.0) for hospital stay. ConclusionsProtocol-based antimicrobial treatment for aspiration pneumonia supports appropriate antimicrobial usage and improves patient quality of life. These findings will assist in the effective treatment of aspiration pneumonia in an aging society.

Abstract PO2-12-10: Age-specific outcomes in breast cancer patients treated with aromatase inhibitors - A national inpatient sample database analysis

Abstract Background: This study aims to investigate the age-specific outcomes of breast cancer patients undergoing aromatase inhibitors therapy. Currently, no research exists on the age-specific differences in outcomes for this patient population. This study seeks to fill this knowledge gap and provide valuable insights into the various outcomes of these patients. Methods: This retrospective study analyzed hospitalization data from the National Inpatient Sample (NIS) between January 2016 and December 2019 using STATA/BE 17.0 for statistical analysis. It focused on breast cancer patients treated with aromatase inhibitors, evaluating outcomes like mortality, length of stay, charges, and clinical outcomes. We used univariate regression and logistic analysis, with ICD-10 codes utilized for data classification. Results: A total of 5,994 weighted hospitalizations were identified, consisting of breast cancer patients being treated with aromatase inhibitors. For patients aged below 65 (n=1,919), the inpatient mortality rate was 1.8% (n=35), while for patients aged 65 and above (n=4,075), it was slightly higher at 2.3% (n=94). However, there was no statistically significant difference in inpatient mortality between the two age groups (adjusted odds ratio [aOR] = 1.21 [0.82-1.78], p=0.339). The average length of stay (LOS) was similar for both age groups, with patients below 65 having a mean LOS of 4.75 days and those aged 65 and above having a mean LOS of 4.71 days. Total charges ($) in the younger population ( < 65) were incurred at a mean of $60,782.73 (56,764.18-64,801.27), compared to lesser charges in the elderly at a mean of $54,734.38 (52,339.83-57,128.94). The occurrence of pathological fractures was higher in patients below 65, with a rate of 1.6% (n=31), compared to 0.8% (n=33) in patients aged 65 and above (aOR = 0.47 [0.28-0.78], p=0.004). Regarding venous thromboembolism (VTE), the occurrence was 5.5% (n=105) in patients below 65 and 4.8% (n=195) in patients aged 65 and above. There was no significant difference between the two age groups (aOR = 0.86 [0.68-1.10], p=0.237). The occurrence of acute cerebrovascular accidents (CVA) was 0.6% (n=11) in patients below 65 and 1.6% (n=65) in patients aged 65 and above, with an aOR of 2.58 (1.38-4.80), indicating a significantly higher likelihood of CVA in the older age group (p=0.003). Patients aged 65 and above had a higher occurrence of myocardial infarction (MI) compared to patients below 65, with rates of 2.1% (n=85) and 0.1% (n=2), respectively. The aOR for MI was 2.35 (1.39-3.98), indicating a significantly higher likelihood of MI in the older age group (p=0.001). There was no statistically significant difference in the occurrence of hypertensive crisis (HTN crisis) between the two age groups (aOR=1.47 [0.93-2.34], p=0.09). Conclusion: Among breast cancer patients receiving aromatase inhibitors, there was no significant difference in in-patient mortality between those aged below 65 and those aged 65 and above. Both age groups had similar lengths of stay and charges incurred. There was no statistically significant difference in VTE and HTN crisis odds. However, patients below 65 had a higher occurrence of pathological fractures, while patients aged 65 and above had a higher likelihood of acute cerebrovascular accidents and myocardial infarction. Further guidelines must be established to improve inpatient morbidity and mortality in this patient population.

Assessing the Impact of the Covid-19 Pandemic on Outcomes of Patient Admitted with Sickle Cell Disease

Introduction: Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy which affects millions of people worldwide. It is caused by a substitution of the glutamic acid (Glu) amino acid with valine (Val) at the sixth position of the β-globin gene, resulting in a mutated hemoglobin tetramer, HbS, in the erythrocytes of affected individuals. This morphology results in sickle-shaped red blood cells and hemolysis when deoxygenated and leads to vaso-occlusion with associated ischemia. SCD is characterized by repeated severe acute pain episodes, acute chest syndrome, and can be complicated by stroke, nephropathy, avascular necrosis, and more. Many studies have shown disparities in outcomes in racial/ethnic minorities as well as in those with lower socioeconomic status. These factors have also been linked to increased risk of COVID-19 infection and infection related mortality. In this study, we aim to explore the baseline characteristics of patients with SCD, prevalence of hospitalizations, and compare inpatient outcomes during the COVID-19 pandemic with those prior to the pandemic. Methods: Nationwide Inpatient Sample (NIS) was queried to determine adult hospitalized patients with a primary diagnosis of SCD using ICD-10 codes. They were stratified into two cohort groups based on year of admission, comparing admissions during 2016-2019 with admission during the year 2020. Primary outcomes assessed were inpatient mortality, length of stay (LOS), and total hospitalization charges. Secondary outcomes included respiratory failure, need for mechanical ventilation, cerebrovascular accident (CVA), myocardial infarction (MI), acute kidney injury (AKI), pulmonary embolism (PE), and need for blood transfusions. Multivariate linear and logistic regression analysis was performed to adjust for confounding variables. Results: A total of 456, 750 patients were hospitalized with SCD. 377, 285 were admitted between 2016-2019 and 79, 465 were admitted during 2020. Age distribution and sex were similar between the two groups. Patients admitted in the year 2020 were older and had more comorbidities when compared to patients admitted during prior years. Distribution of race, insurance type, hospital type, hospital size, hospital locations, and household income was not significantly different between the two groups. In 2020 patients admitted with SCD had greater odds of developing acute respiratory failure and PE, though the overall prevalence of these secondary outcomes were very low (3.6% and 0.80% respectively). Despite these outcomes, there was no significant difference in inpatient mortality (0.31% vs. 0.23%) for SCD patients admitted during 2020 when compared to prior years. In addition, the length of hospital stay was not significantly different in these two groups as well (5.1 vs. 4.9 days). Finally, patients admitted in 2020 incurred significantly higher hospital costs than SCD during pre-pandemic years ($42, 307 vs. $36, 087). Conclusion: SCD is the most common hemoglobinopathy in the United States. The African American population is most commonly affected by this disease. In addition, it is well known that this racial minority suffers inequities in accessing and receiving health care, which is associated with worse overall outcomes. During the COVID-19 pandemic, reduced access to hospital services combined with fear of exposure to the virus, led to a significant drop in overall access to healthcare and treatment. In this study, we found that those with SCD admitted during the COVID-19 pandemic overall had more comorbidities and more commonly had respiratory failure and pulmonary embolism, yet there was no change in inpatient mortality and LOS for these patients. Although disparities existed during the pandemic, it is fortunate that SCD itself did not serve as an additional risk factor for inpatient mortality and hospitalization duration.

Abstract 14774: Differences in the In-Patient Mortality in Marantic Endocarditis Per Etiology: Systematic Review of Case Reports

Introduction: Non-bacterial thrombotic endocarditis (NBTE; also known as marantic endocarditis) is a unique entity characterized by sterile fibrin deposits on valves caused by hypercoagulability and endocardial injury. Literature is limited regarding the distinction between its causes based on in-hospital mortality. Hypothesis: Would a significant difference in in-patient mortality be present in NBTE admissions depending on etiology? Methods: A review of the literature using the PubMed, Embase, Cochrane, and Web of Science databases was conducted to obtain case reports and series reporting NBTE from inception to September 2022. Crude and univariate analyses were performed. Results: 396 case reports and 20 case series were identified, of which 450 patients were extracted. Females represented 64% of our sample (median age: 46, interquartile range [IQR]: 32 - 60) while 36% were males (median age: 50, IQR: 36 - 64). Overall all-cause in-hospital mortality was 36%. NBTE was associated with cancer in 202 (47%), autoimmune disease in 191 (45%), and other causes in 34 (8%) cases. Older population and cancer etiology were associated with higher mortality (OR: 1.77, CI 95%: 1.19 - 2.62 & OR: 8.29, CI 95%: 4.97 - 13.83, respectively). A significant decrease in mortality is noted in the more recent years compared to the 20 th century (OR: 0.10, 95% CI: 0.06 - 0.18). Conclusions: Although an improvement in all-cause in-hospital mortality for admission related to NBTE has been noticed in recent years, cancer as an etiology and old age are two risk factors associated with higher mortality.

Abstract 13441: Outcomes of Percutaneous Atrial Septal Defect Closure Following Mitraclip and Transcatheter Mitral Valve Replacement

Introduction: Data on clinical outcomes of percutaneous closure of iatrogenic atrial septal defect (PC-ASD) in patients undergoing transcatheter edge-to-edge repair (TEER) or mitral valve replacement (TMVR) remains limited. We used a real-world USA database to evaluate the differences in the in-hospital outcomes between both groups. Hypothesis: Is there a clinical significance for PC-ASD in patients undergoing TEER or TMVR? Methods: We used the National Inpatient Sample (2015-2020) by utilizing ICD-10 codes to identify all patients who underwent TEER or TMVR with or without PC-ASD. Multivariate logistic regression was used for adjusted outcomes (adjusted odds ratio [aOR]). Results: A total of 44,065 eligible weighted hospitalizations were included: 39,625 (89.9%) of the patients underwent TEER and 4,440 (10.1%) underwent TMVR. Rates of PC-ASD were higher in TMVR group compared to TEER group (10.7% vs. 2.0%, p<0.01). In patients who underwent TEER without PC-ASD, PC-ASD was more associated with acute heart failure (AHF) (aOR 1.42 [1.19-1.68], p<0.01) and longer hospitalizations (aOR 1.64 [1.41-1.89], p<0.01), without significant difference in inpatient mortality (aOR 0.97 [0.61-1.54], p<0.01), cardiogenic shock (aOR 1.13 [0.85-1.51], p=0.21), need for mechanical circulatory support (MCS) (aOR 0.98 [0.61-1.54], p=0.18), and stroke. Compared to patients who underwent TMVR without PC-ASD, PC-ASD was associated with higher inpatient morality (aOR 1.65 [1.13-2.4], p<0.01), need for MCS (aOR 1.91 [1.33-2.73], p<0.01) without significant difference in AHF (aOR 1.19 [0.94-1.51], p=0.18] and cardiogenic shock (aOR 0.83 [0.56-1.22], p=0.43). Remarkably, PC-ASD was less associated with stroke (aOR 0.27 [0.10-0.72], p<0.01). Conclusions: Rates of PC-ASD after TEER were lower than after TMVR and were associated with worse in-hospital mortality and need for MCS in TMVR but not in TEER. Also, PC-ASD was less associated with stroke after TMVR.

Anatomical location, risk factors, and outcomes of lower gastrointestinal bleeding in colorectal cancer patients: a national inpatient sample analysis (2009-2019).

This study aimed to investigate the incidence, predictors, and impact of lower gastrointestinal bleeding (LGIB) on inpatient mortality among colorectal cancer patients, due to its clinical significance and potential influence on patient outcomes. We conducted a retrospective analysis of data from the National Inpatient Sample database between 2009 and 2019, including 2,598,326 colorectal cancer patients with and without LGIB. Univariate and multivariate logistic regression analyses were performed to determine predictors of LGIB and its association with inpatient outcomes. The highest incidence of LGIB was observed in rectal cancer patients (3.8%), followed by distal colon cancer patients (1.4%) and proximal colon cancer patients (1.2%). Several factors were significantly associated with LGIB, including older age; male sex; certain racial such as Black, Hispanic, and Asia/Pacific Islander patients; or lower socioeconomic status. Multivariate analysis identified independent predictors of LGIB, such as severe sepsis, use of anticoagulants, long-term use of aspirin or antiplatelet drugs, palliative care, malnutrition, cachexia, chemotherapy or immunotherapy, metastasis, alcohol abuse, hypertension, obesity, and family history of digestive cancer. No significant difference in inpatient mortality was observed between patients with and without LGIB. Our study underscores the importance of considering colorectal cancer location and identified risk factors for LGIB assessment. Clinicians should address modifiable risk factors and healthcare disparities. Future research should explore underlying mechanisms, targeted interventions, and long-term outcomes beyond inpatient mortality.

Prothrombin Complex Concentrate vs Factor VII for Refractory Bleeding in Cardiac Surgery

BackgroundPerioperative bleeding remains an important complication of cardiac surgery. Current guidelines support goal-directed use of coagulation factor concentrates in refractory bleeding, but the optimal strategy is unclear. Four-factor prothrombin complex concentrate (4F-PCC) has theoretical advantages over recombinant activated factor VII (rFVIIa) because of expanded mechanistic targets and lower rates of adverse events, but comparative data are limited. MethodsWe pursued a retrospective cohort study assessing the implementation of an institutional treatment algorithm for refractory bleeding in cardiac surgery that mediated a practice change in preferred factor product from rFVIIa to 4F-PCC. All cardiac surgery patients at 2 large community hospitals who received 4F-PCC or rFVIIa during 2019-2020 were assessed for inclusion. The primary outcome was all-cause in-hospital mortality. ResultsA total of 42 patients met study criteria. Mortality was nonsignificantly lower in the 4F-PCC group (7.1% vs 28.6%; P = .16), as were median total blood products transfused (15 vs 25.5 units; P = .11), although median units of cryoprecipitate were significantly lower (0.5 vs 2 units; P = .01). Average factor product medication charge per patient was significantly lower in the 4F-PCC group ($9772 vs $50,293; P < .001). ConclusionsA 4F-PCC–based strategy for refractory bleeding in cardiac surgery was associated with reduced cryoprecipitate transfusion and medication costs without significant differences in inpatient mortality or total transfusion exposure. Trends toward decreased mortality and transfusions observed in this quality improvement study should be explored in larger prospective trials.

Delayed vs early cardioversion in patients with paroxysmal atrial fibrillation: a population-based study (2015-2020).

Aim: There is limited data on clinical outcomes of delayed cardioversion (DCV) compared with early cardioversion (ECV) in paroxysmal atrial fibrillation (AF) patients. Methods: We utilized data from National Inpatient Sample (2015-2020) and propensity-score matched analysis to determine adjusted odds ratio (aOR) of major clinical outcomes, including 17,879 AF cases: 9725 and 8154 underwent ECV and DCV, respectively. Results: Compared with ECV, DCV was associated with higher odds of acute heart failure (AHF; aOR 1.79 [1.67-1.92]; p<0.01), median length of stay (4 vs 2days; p<0.01) and cost of hospitalization ($33,410 vs $21,738; p<0.01) with no significant difference in inpatient mortality and other cardiovascular and neurological outcomes. Conclusion: Compared with ECV, DCV was associated with more AHF and resource utilization.

Association between smoking status and inpatient outcomes of acute cholangitis in the United States: a propensity matched analysis.

Acute cholangitis (AC) is an infection of the biliary tract superimposed on stasis. This study aimed to investigate the effects of smoking on inpatient outcomes of AC. We identified primary AC hospitalizations using the National Inpatient Sample database (2017-2020). Using a 1:1 matching method, we created a matched comparison cohort of AC patients who were non-smokers, based on demographics, hospital characteristics and comorbidities. We matched 3960 smoker patients with 3960 non-smoker patients within the AC population. Non-smokers were older than smokers (70 vs. 59 years, P<0.001). Smokers had a stronger association with bile duct calculi (74.37% vs. 69.29%, P<0.001) and other bile duct disorders (clots, parasites, extrinsic compression and other rare disorders) (6.82% vs. 5.05%, P=0.011). No significant difference in inpatient mortality, median length of stay (LOS), or median inpatient cost (MIC) was found between the matched cohorts (P>0.05). However, smoking was associated with higher odds of complications, including sepsis without shock (0.88% vs. 0.51%, P=0.042), sepsis with shock (1.26% vs. 0.51%, P<0.001), biliary pancreatitis (6.57% vs. 4.42%, P<0.001) and myocardial infarction (6.19% vs. 3.54%, P<0.001), as well as a greater need for inpatient endoscopic retrograde cholangiopancreatography (ERCP) (72.85% vs. 63.76%, P<0.001) and early ERCP (50.76% vs. 42.32%, P<0.001) compared to non-smokers. This study found no difference in mortality, LOS, or MIC in acute cholangitis-related hospitalizations associated with smoking. However, smoking was associated with a higher risk of complications and a greater need for ERCP and early ERCP.

Sex Differences in Clinical Profile and Outcome After Percutaneous Coronary Intervention for Chronic Total Occlusion

BackgroundThere are limited data around sex differences in the risk profile, treatments and outcomes of percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) lesions in contemporary interventional practice. We investigated the impact of sex on clinical and procedural characteristics, complications and clinical outcomes in a national cohort. Methods & resultsWe created a longitudinal cohort (2006–2018, n = 30,605) of patients with stable angina who underwent CTO PCI in the British Cardiovascular Intervention Society (BCIS) database. Clinical, demographic, procedural and outcome data were analysed in two groups stratified by sex: male (n = 24,651), female (n = 5954). Female patients were older (68 vs 64 years, P < 0.001), had higher prevalence of diabetes mellitus (DM), hypertension (HTN) and prior stroke. Utilization of intravascular ultrasound (IVUS), drug eluting stents (DES), radial or dual access and enabling strategies during CTO PCI were higher in male compared to female patients. Following multivariable analysis, there was no significant difference in in-patient mortality (adjusted odds ratio (OR):1.40, 95 % CI: 0.75–2.61, P = 0.29) and major cardiovascular and cerebrovascular events (MACCE) (adjusted OR: 1.01, 95 % CI: 0.78–1.29, P = 0.96). The crude and adjusted rates of procedural complications (adjusted OR: 1.37, 95 % CI: 1.23–1.52, P < 0.001), coronary artery perforation (adjusted OR: 1.60, 95 % CI: 1.26–2.04, P < 0.001) and major bleeding (adjusted OR: 2.06, 95 % CI: 1.62–2.61, P < 0.001) were higher in women compared with men. ConclusionFemale patients treated by CTO PCI were older, underwent lesser complex procedures, but had higher adjusted risk of procedural complications with a similar adjusted risk of mortality and MACCE compared with male patients.

Abstract 15751: Trends and Disparities in Pulmonary Arterial Hypertension Over the Past Decade: A National Inpatient Sample Database Study

Introduction: Pulmonary arterial hypertension (PAH) is well defined, however, the trends and disparities have not been studied recently after the update in guidelines. Methods: We utilized National Inpatient Sample Database 2010-2019 to identify the cohort with principal diagnosis of PAH using ICD-9 and 10 codes. Primary outcome analysis included the crude admission rate of PAH per 1,000,000 adult hospitalizations during each calendar year stratified by sex, race, and median household income (MHOI). Secondary outcome analysis included trends in inpatient mortality rate, mean length of hospital stay (LOS), and mean total hospital charges (THC). Results: There were a total of 341 million admissions from 2010-2019 out of which 0.004% (13644) were adults admitted with principal diagnosis of PAH. There was no significant difference in year on year admissions in the last decade (Figure). Most patients were aged 18-65 when diagnosed (OR 1.73, 95% CI 1.55-1.92). Females were twice as likely to be diagnosed with PAH than males (OR 2.40, 95% CI 2.17-2.64). African Americans (OR 1.35, 95% CI 1.21-1.50) and Asian/Pacific Islander (OR 1.22, 95% CI 1.04-1.42) were at slightly more risk of PAH. There was no significant difference in inpatient mortality among patients with principal diagnosis of PAH over the last decade. Although mortality increased with increasing age (OR 1.29. 95% CI 1.29-3.33 for age &gt; 65) (OR 1.79, 95% CI 1.45-2.77) but did not defer when stratified for gender , race or year. Conclusion: Admissions for principal diagnosis of pulmonary arterial hypertension have remained unchanged over the last decade. Female sex, age and median house hold income is associated with increased risk for PAH.

Reducing oncology readmissions through a multidisciplinary discharge approach.

6561 Background: Hospital readmissions are associated with increased health care utilization and unfavorable patient outcomes. Oncology patients have an increased risk of hospital readmission compared to the general patient population. The 30-day readmission rate for cancer patients at our institution is 27.7% which is higher than the reported national average of 20.2%. We sought to reduce 30-day hospital readmission rates by 25% for solid tumor oncology patients through a prospective integrated multidisciplinary discharge approach. Methods: Hospital readmissions for adult patients with a known solid tumor cancer diagnosis admitted to the oncology service at UVA from Jan 2019 – Apr 2019 were identified. Baseline information on tumor type, reason for readmission, interventions, length of stay (LOS), and inpatient morbidity and mortality (including ICU admission and transition to hospice) were collected via retrospective review. Qualitative and quantitative tools including process maps, cause-and-effect diagrams, Pareto charts, and priority matrix were used to identify potential areas for intervention. Two PDSA cycles were implemented: daily multidisciplinary discharge rounds with physicians, nursing, social work, case management, and PT/OT (PDSA1), and a templated discharge email to patients’ primary oncology team including attending oncologist, mid-level providers, nurse coordinator, pharmacist, and urgent care team (PDSA2). An SPC chart with 3-σ limits and t-test of unequal variance with 2-sided p-value was used to evaluate impact on readmission rates from baseline to PDSA2. Results: Following PDSA1 (May 2019 – Oct 2019), the 30-day readmission was 25.7%; PDSA2 was postponed due to COVID-19, however the 30-day readmission rate remained stable during the pandemic. Following PDSA2 (Sept 2021 – Dec 2021), the 30-day readmission rate was 18.2% corresponding to an absolute decrease of 34.3% which was statistically significant (p≤0.05). This was associated with a trend towards increased LOS, rate of ICU admission, and case-mix severity index although not statistically significant. There was no significant difference in inpatient mortality or transition to hospice (Table). Conclusions: Implementation of multidisciplinary discharge rounds and templated discharge communication resulted in a significant decrease in rate of 30-day readmissions for solid tumor oncology patients. There was a trend towards increased LOS and ICU admissions without increased inpatient mortality. Improvement in discharge email compliance and implementation of an urgent symptom clinic may further reduce the 30-day readmission rate. [Table: see text]

Controlled Study of Decision-Making Algorithms for Kidney Replacement Therapy Initiation in Acute Kidney Injury.

AKI requiring KRT is associated with high mortality and utilization. We evaluated the use of an AKI Standardized Clinical Assessment and Management Plan (SCAMP) on patient outcomes, including mortality, hospital length of stay, and intensive care unit length of stay. We conducted a 12-month controlled study in the intensive care units of a large academic tertiary medical center. We alternated use of the AKI-SCAMP with use of a "sham" control form in 4- to 6-week blocks. The primary outcome was risk of inpatient mortality. Prespecified secondary outcomes included 30- and 60-day mortality, hospital length of stay, and intensive care unit length of stay. Generalized estimating equations were used to estimate the effect of the AKI-SCAMP on mortality and length of stay. There were 122 patients in the AKI-SCAMP group and 102 patients in the control group. There was no significant difference in inpatient mortality associated with AKI-SCAMP use (41% versus 47% control). AKI-SCAMP use was associated with significantly reduced intensive care unit length of stay (mean, 8; 95% confidence interval, 8 to 9 days versus mean, 12; 95% confidence interval, 10 to 13 days; P<0.001) and hospital length of stay (mean, 25; 95% confidence interval, 22 to 29 days versus mean, 30; 95% confidence interval, 27 to 34 days; P=0.02). Patients in the AKI-SCAMP group were less likely to receive KRT in the context of physician-perceived treatment futility than those in the control group (2% versus 7%; P=0.003). Use of the AKI-SCAMP tool for AKI KRT was not significantly associated with inpatient mortality, but was associated with reduced intensive care unit length of stay, hospital length of stay, and use of KRT in cases of physician-perceived treatment futility.

Abstract 9998: Association of Hospital Procedural Volume with Outcomes in Heart Transplantation

Background: Studies have shown an inverse relationship between procedural volume and outcomes for numerous procedures. The aim of this study was to evaluate the association of heart transplant (HT) procedural volume and in-hospital clinical outcomes. Methods: We conducted a retrospective analysis of adult hospitalizations from the Nationwide Readmissions Database (NRD) 2018. International Classification Diseases (ICD) codes were used to identify patients who underwent HT. Hospitals were categorized into 3 groups on the basis of tertiles of annual procedural volume: low (1-14 procedures/year), medium (14 to 27 procedures /year), and high (28 to 115 procedures /year). Hierarchical mixed effect logistic regression modeling with hospital as a random effect was used to examine the association between hospital procedural volume and outcomes. These models were adjusted for patient-level and hospital-level characteristics. Low volume hospitals were used as the reference category. Results: This study included 1689 procedures performed across 69 hospitals ( Table ). On multivariate analysis, there was no statistically significant difference in inpatient mortality, discharge to nursing home/long term care facility, stroke, acute kidney injury, bleeding requiring transfusion, pericardial complications, vascular complications or length of stay among low, medium and high-volume centers ( Table ). Interestingly there was a trend toward lower length of stay and lower inpatient mortality in high volume centers that did not reach statistical significance. Conclusion: Our study did not find any association between hospital HT procedural volume and clinical outcomes. Further studies are needed to confirm this.

Diabetic emergencies presenting during the COVID-19 pandemic: A retrospective case analysis.

IntroductionCOVID‐19 has triggered a global pandemic and is an emerging situation. Diabetes has been associated with significant mortality in SARS and MERS‐COV infections. Patients with diabetes are at risk of COVID‐19 triggering diabetic emergencies due to known and unknown mechanisms. There is little evidence overviewing the clinical course of COVID‐19 patients who either present or have diabetic emergencies during their disease course.MethodsWe conducted a retrospective case analysis of all patients admitted to our hospital during the COVID‐19 pandemic. The inclusion criteria were all patients receiving treatment for COVID‐19 and either presenting with a diabetic emergency on admission or developing an emergency during their admission. Data collected for the study were all routinely collected data as part of the admission. We compared these data to nine patients with no COVID‐19.ResultsThirty patients received treatment for a diabetic emergency, of which 21 also received treatment for COVID‐19. Significant differences were found between pH and bicarbonate on admission between RT‐PCR‐positive and both RT‐PCR‐negative and non‐COVID‐19 patients. Other results approaching significance include ALP and eGFR.DiscussionPatients suffering from COVID‐19 and diabetes concurrently can suffer from profound metabolic disturbance, with a significant difference in inpatient mortality. However further, prospective detailed investigation into biochemical processes is needed to fully elucidate underlying mechanisms that affect these patients' outcomes.

Racial differences in the outcomes of IBD hospitalizations: a national population-based study.

There are scarce data describing the outcomes of hospitalized patients admitted with inflammatory bowel disease (IBD) stratified by race. In this retrospective cohort study, we evaluated the difference in outcomes between adult white and black patients hospitalized with a principal diagnosis of inflammatory bowel disease. Data were obtained from the 2016 and 2017 National Inpatient Sample (NIS) database. Our primary outcome was inpatient mortality while the secondary outcomes were hospital length of stay (LOS), total hospital charges (THC), red blood cell (RBC) transfusion, diagnosis of bowel perforation, and severe sepsis with septic shock. We conducted the analysis using STATA software. We used propensity-matched multivariate regression analysis to adjust for potential confounders. Among 71 million hospital hospitalizations, we found 177,574 hospitalizations with a principal diagnosis of IBD, with 24,635 (13.9%) for black patients, 124,899 (70.3%) for white patients, and 28,040 (15.8%) were for others. There was no significant difference in inpatient mortality for black vs white patients. Among secondary outcomes, white compared to black patients had increased odds of having a diagnosis of bowel perforation when admitted with a diagnosis of IBD while there was no difference in the odds of developing septic shock. White patients admitted with a diagnosis of UC were also found to have increased total LOS and THC. White patients hospitalized with a principal diagnosis of IBD had no difference in inpatient mortality or septic shock but had worse outcomes such as increased odds of bowel perforation compared to black patients.

Comparing outcomes of transcatheter versus surgical aortic valve replacement in patients with atrial arrythmias

Abstract Introduction In patients with severe aortic valve stenosis, clinical trials have demonstrated a similar mortality risk with transcatheter aortic valve replacement (TAVR) compared to surgical aortic valve replacement (SAVR) in low to intermediate-risk patients. However, data comparing these procedures in patients with atrial arrhythmias is lacking. Purpose This study aimed to evaluate and compare the in-hospital mortality and outcomes of TAVR and SAVR for severe aortic stenosis in patients with atrial fibrillation or atrial flutter. Methods We performed a retrospective cross-sectional analysis using the 2018 National Inpatient Sample. Patients aged 50 years and older with TAVR or SAVR related hospitalizations were identified. Patients with endocarditis and those undergoing coronary artery bypass grafting or other valvular procedures were excluded. Propensity score matching was utilized to mitigate selection bias. The scoring was based on a multivariate logistic regression model accounting for age, gender, race, hospital type, hospital region, hospital teaching status, median household income, and medical comorbidities. Using 8-to-1-digit match, we paired each admission in TAVR group with one admission in SAVR group. Results In 2018, a total of 3487 TAVRs and 1466 SAVRs were performed in patients who had atrial fibrillation or atrial flutter. TAVR and SAVR had no statistically significant difference in inpatient mortality (0.9% vs 0.8%, p=0.79). However, SAVR was associated with higher odds of cardiogenic shock (OR 1.82; 95% CI 1.41–2.35, p&amp;lt;0.0001), acute kidney injury (OR 2.29; 95% CI 1.77–2.97, p&amp;lt;0.0001), mechanical ventilation (OR 2.06; 95% CI 1.75–2.43, p&amp;lt;0.0001), pneumonia (OR 1.76; 95% CI 1.37–2.28, p&amp;lt;0.0001), pneumothorax (OR 6.38; 95% CI 4.17–9.76, p&amp;lt;0.0001) and postoperative hemorrhage (OR 3.21; 95% CI 2.13–4.85, p&amp;lt;0.0001). On the contrary, SAVR was associated with decreased likelihood of subsequent cardiac conduction disorders (OR 0.63; 95% CI 0.51–0.79, p&amp;lt;0.0001) and pacemaker implantation (OR 0.69; 95% CI 0.49–0.98, p=0.037). SAVR was associated with an increased length of hospitalization (3.9 vs. 8.4 days, p&amp;lt;0.0001), with no difference in medical costs. Conclusion Inpatient mortality for TAVR and SAVR was similar in patients with atrial fibrillation and atrial flutter. TAVR was associated with a lower risk of inpatient complications, indicating greater suitability for high-risk patients. However, clinicians should be cognizant of the increased risk for cardiac conduction disorders after TAVR, necessitating pacemaker implantation. Funding Acknowledgement Type of funding sources: None.

S3354 Impact of Multiple Sclerosis on the Outcomes of Patients Hospitalized With Inflammatory Bowel Disease

Introduction: It has been reported that there is a possible association between inflammatory bowel disease (IBD) and multiple sclerosis (MS). Some studies suggest that there are familial links and shared genetic factors between two diseases, and MS course appears to be milder in patients with concomitant IBD. On the other hand, there is a lack of studies on how the outcomes of IBD are affected by MS. Thus, we aim to assess the outcomes of IBD in patients with concomitant MS. METHODS: Patients hospitalized with IBD from the National Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality 2014 were selected. Diagnoses were identified by using ICD-9 CM codes. Outcomes of IBD were compared between the groups with and without MS. The outcomes of interest were inpatient mortality, length of stay, total hospital charge, and IBD complications including malnutrition, penetrating disease, stricturing disease/bowel obstruction, colectomy, and ileostomy. Chi-squared tests and independent t-tests were used to compare proportions and means respectively. Multivariate logistic regression analysis was performed to determine if MS is an independent predictor for the outcomes, adjusting for age, sex, race, and the Charlson Comorbidity Index. RESULTS: Among 34,374 patients with IBD identified in the study, 132 patients had MS. There were no statistically significant differences in inpatient mortality (0% vs 0.23%, p = 0.58), length of stay (4.4 days vs 4.6 days, p = 0.72), and total hospital charge ($33,730 vs $36,727, p = 0.48). After adjusting for age, sex, race, and the Charlson Comorbidity Index, there were no statistically significant differences in IBD complications including malnutrition (aOR 0.92, 95% CI: 0.38-2.27, p = 0.86), penetrating disease (aOR 0.43, 95% CI: 0.14-1.35, p = 0.15), stricturing disease/bowel obstruction (aOR 1.12, 95% CI: 0.70-1.79, p = 0.63), colectomy (aOR 0.63, 95% CI: 0.23-1.71, p = 0.36), and ileostomy (aOR 0.86, 95% CI: 0.32-2.33, p = 0.76). CONCLUSION: There were no differences in inpatient mortality, length of stay, total hospital charge, and IBD complications between groups with and without MS. Despite possible genetic links between IBD and MS, our study suggests that outcomes of IBD are not affected by the presence of MS.
