Prevalence, Clinical Features and Outcomes of Patients with Acute Aortic Dissection and Concomitant Lower Extremity Malperfusion

Objective: The aim of this study was to describe the prevalence and clinical characteristics of patients presenting with lower limb malperfusion (LLM) following an aortic dissection, and the outcomes of the patients repair of the dissection as the initial operative procedure. Method: We performed a retrospective medical record review at our single center of patients who presented with an aortic dissection complicated by LLM from January 2019 to June 2023, and analyzed the incidence, clinical characteristics, prognosis and reintervention of these patients. Result: The incidence of patients with an aortic dissection complicated by LLM was 6.3% (39/617) with mortality rate of 23% (9/39). LLM cases were associated with malperfusion of other organs in 77% (30/39) of patients. All surgical patients underwent initial aortic central repair, with a mortality rate of 26% (8/30). Mortality rates were 31.8% (7/22) for type A dissections and 12.5% (1/8) for type B dissections. Immediate femoral-femoral bypass grafting was performed in 10% (3/30) of cases following aortic central repair, with the majority of patients experiencing significant improvement in LLM with aortic central repair alone. The postoperative readmission rate due to LLM was 6.7% (2/30). Conclusion: Aortic dissection with lower limb malperfusion (LLM) is associated with increased pre- and postoperative mortality, especially in Type A aortic dissections versus Type B. However, for survivors of initial central aortic repair surgery, the rates of amputation and readmission for LLM are low.

Evaluation of patients who re-admitted to the emergency department within 24 hours

Aim: It was conducted to investigate the demographic and clinical characteristics of patients who re-admitted to the emergency department within 24 hours and to contribute to studies on reducing the re-admission rate. Methods: The data of patients who re-admitted to the emergency department within 24 hours between November 2021 and September 2023 in a secondary level public hospital were retrospectively examined. Data regarding the patients' demographic information, admission dates and times, clinical characteristics, examinations, diagnoses, consultations, hospitalization and referral status were obtained from the hospital automation system. Results: 496270 patients admitted to the emergency department during the study period. 6991 (1.4%) of the patients were admitted to the emergency department again within 24 hours. 40.3% of these patients were between the ages of 19-35 and 52.4% were women. The most common reason for re-admission to the emergency department was upper respiratory tract diseases. It was determined that 66.7% of the patients applied to the emergency department again 13-24 hours after their first admission. In their second admission, 43 patients were hospitalized or transferred for various reasons; It was determined that 1 of these patients died 5 months after being admitted to the intensive care unit. Conclusion: Effective triage practices, directing green area patients to family physicians, making the referral chain effective, increasing health literacy, making an accurate diagnosis, allocating appropriate time to patients and explaining the treatment and expectations from treatment, ensuring that patients referred to polyclinics are evaluated as soon as possible and returned to the emergency department will significantly reduce applications.

Comparison of a Risk Calculator With Frailty Indices in Patients Undergoing Lung Cancer Resection.

While frailty has gained attention for its utility in risk stratification, no studies have directly compared them to existing risk calculators. The objective of this study was to compare the risk stratification of the American College of Surgeons Surgical Risk Calculator (ACS-SRC), the Revised Risk Analysis Index (RAI-rev), and the Modified Frailty Index (5-mFI). The primary outcomes were 30-day postoperative morbidity, 30-day postoperative mortality, unplanned readmission, unplanned reoperation, and discharge disposition other than home. Patients undergoing anatomic lung resection for primary, nonsmall cell lung cancer were identified within the ACS National Quality Improvement Program (ACS NSQIP) database. Tools were compared for discrimination in the primary outcomes. 9663 patients undergoing anatomic lung resection for cancer between 2012 and 2014 were included. The cohort was 53.1% female. Median age at diagnosis was 67 (IQR 59-74) years. Perioperative morbidity and mortality rates were 10.9% (n = 1048) and 1.6% (n = 158). Rates of 30-day postoperative unplanned readmission and reoperation were 7.5% (n = 725) and 4.8% (n = 468). The ACS-SRC had the highest discrimination for all measured outcomes, as measured by the area under the receiver operating curve (AUC) and corresponding confidence interval (95% CI). This included perioperative mortality (AUC 0.74, 95% CI 0.71-0.78), compared to RAI-rev (AUC 0.66, 95% CI 0.62-0.69) and 5-mFI (AUC 0.61, 95% CI 0.57-0.65; p < 0.001). The RAI-rev and 5-mFI had similar discrimination for all measured outcomes. ACS-SRC was the perioperative risk stratification tool with the highest predictive discrimination for adverse, 30-day, postoperative events for patients with cancer treated with anatomic lung resection.

Application of the Clinical Outcomes, Healthcare Resource Utilization, and Related Costs Model in Chronic Obstructive Pulmonary Disease Patients

Introduction: The change in prevalence and management of chronic obstructive pulmonary disease (COPD) led to changes in outcomes and costs. We aimed to assess current clinical outcomes, resource utilisation, and costs in COPD. Methods: Retrospective, observational study of a cohort of consecutive COPD patients who visited the emergency department (ED) of a large tertiary hospital in 2018. The study measured baseline characteristics, 30-day and 1-year mortality, readmission, re-ED visit rates, and costs using the Clinical Outcomes, HEalthcare REsource utilisatioN, and relaTed costs (COHERENT) model, validated for heart failure. This model, featuring a colour graphic system, tracks time spent in different clinical situations (home, ED, hospital), considering vital status, healthcare resource use, and related costs. Results: In 2018, 2,384 patients with a primary COPD diagnosis visited the ED. The average age was 76 years, with 40% women. Observed mortality rates were 7.6% in-hospital, 8.5% at 30 days, and 23.4% at 1 year. The readmission rates were 9.9% and 36.1%, respectively. The cohort’s 1-year cost was approximately EUR 14.6 million (USD 15.95 million), with a median cost per patient of EUR 3,298 (USD 3,603.96). Hospitalisation incurred the highest costs, with initial hospitalisation and readmissions accounting for 44.7% and 42.6% of expenditures, respectively. Conclusion: One-year mortality and readmission rates for patients with COPD visiting the ED remain high with a significant economic impact on the health system. This burden justifies special programs to improve their care.

Home-Time, Mortality, and Readmissions Among Patients Hospitalized With Heart Failure: A Baseline Prior to IMPLEMENT-HF.

Home-time is an emerging, patient-centered outcome that represents the amount of time a patient spends alive and outside of health care facility settings, comprising of hospitals, skilled nursing facilities, and acute rehabilitation centers. Studies evaluating home-time in the context of heart failure are limited, and the impact of quality improvement interventions on home-time has not been studied. Medicare beneficiaries aged 65 years or older who were hospitalized for heart failure in the Get With the Guidelines-Heart Failure registry between 2019 and 2021 were included. Postdischarge home-time, mortality, and readmission rates at 30 days and 1 year were calculated with the goal of establishing baseline metrics before the initiation of IMPLEMENT-HF, a multicenter quality improvement program aimed at improving heart failure management. Overall, 66 019 patients were included across 437 sites. Median 30-day and 1-year home-time were 30 (18-30) and 333 (139-362) days, respectively. Only 22.1% of patients experienced 100% home-time in the year after discharge. Older patients spent significantly less time at home, with a median 1-year home-time of 302 (86-359) compared with 345 (211-365) days in patients over 85 and those between 65 and 74 years old, respectively (P<0.001). Black patients also experienced the least amount of home-time with only 328 (151-360) days at 1-year follow-up. Rates of heart failure readmission and all-cause mortality 1-year post-discharge were high at 29.8% and 37.0%, respectively. In this contemporary multicenter cohort, patients hospitalized with heart failure spent a median of 91.2% of their time in the year after discharge alive and at home, largely driven by high mortality rates. These findings serve as a preimplementation baseline for IMPLEMENT-HF, which will evaluate the impact of targeted heart failure initiatives on home-time and other clinical outcomes.

Early Hemorrhagic Complications after Holmium Laser Enucleation of the Prostate in Patients Undergoing Antithrombotic Therapy: A Retrospective Analysis from a High-Volume Centre.

Objectives: This study intends to evaluate early hemorrhagic complications after holmium laser enucleation of the prostate (HoLEP) in patients undergoing antithrombotic therapy. Methods: The data of patients undergoing HoLEP between January 2020 and February 2023 were retrospectively analysed. Patients were clustered into three groups: (1) no antithrombotic therapy; (2) antiplatelet (AP) therapy; and (3) anticoagulant (AC) therapy. Pre-, intra-, and post-operative variables were compared. A logistic regression model was built to identify predictors of post-operative hemorrhagic complications. Results: A total of 338 patients underwent HoLEP, including 212 who received no antithrombotic therapy (62.7%), 76 who received AP (22.5%), and 50 who received AC (14.8%). Intra-operative outcomes did not show any significant difference. A significant difference was observed in terms of catheterisation time (p = 0.001) and length of hospital stay (p < 0.001), favouring patients who did not receive antithrombotic therapy. Early post-operative hemorrhagic complications (<30 days) included re-admissions for macrohematuria (3.5%), transfusions (2.4%), and endoscopic re-interventions for bleeding (1.2%). A comparison between the groups showed significant differences for both re-admission (p < 0.001) and transfusion rates (p = 0.01), favouring patients who did not receive antithrombotic therapy. The re-intervention rate did not show any significant difference between the groups (p = 0.1). In multivariate analysis, AC therapy was identified as an independent predictor of those complications (OR 4.9, p = 0.005). Conclusions: HoLEP is a safe and effective procedure for patients undergoing antithrombotic therapy. Both AP and AC therapies are associated with longer catheterisation and hospitalisation times. AC therapy is shown to be a predictor of minor post-operative hemorrhagic complications.

Relationships Between Quality of Discharge Teaching, Readiness for Hospital Discharge, Self-Efficacy and Self-Management in Patients With First-Episode Stroke: A Cross-Sectional Study.

The study investigated the influence of quality of discharge teaching (QDT) on readiness for hospital discharge (RHD) and pathways involved in patients with first-episode stroke, aiming to provide a theoretical framework for enhancing RHD levels and reducing readmission rates. Cross-sectional study. A total of 372 inpatients completed the Quality of Discharge Teaching Scale, Readiness for Hospital Discharge Scale, Chronic Disease Self-efficacy Scale and Southampton Stroke Self-Management Questionnaire. Structural equation modelling and Pearson's correlation analysis were utilised to elucidate relationships and action pathways among these variables. The correlation analysis demonstrated significant positive pairwise correlations between QDT, RHD, self-efficacy and self-management (r = 0.376-0.678, p < 0.01). The final model exhibited a good fit with the following indices: χ2/df = 3.286, RMSEA = 0.078, SRMR = 0.0303, GFI = 0.984, AGFI = 0.926, CFI = 0.991 and TLI = 0.970. The impact of QDT on RHD in patients with first-episode stroke was observed through one direct and three indirect pathways: (1) QDT exerted a direct influence on RHD (p < 0.001); (2) QDT indirectly influenced RHD via self-efficacy (p < 0.001); (3) QDT indirectly affected RHD through self-management (p < 0.001); and (4) QDT had an indirect effect on RHD via both self-efficacy and self-management (p < 0.05). QDT was found to directly influence RHD in patients with first-episode stroke and also exerted indirect effects through self-efficacy and self-management, either independently or in combination. Early screening of RHD levels in patients before discharge is recommended, along with the enhancement of QDT through the development of tailored guidance plans according to different disease stages, ultimately improving RHD levels and facilitating a safer transition from hospital to home or community. Healthcare professionals should assess both QDT and RHD levels to provide targeted interventions. The establishment of transitional care teams and implementation of long-term poststroke management are essential for reducing stroke recurrence and mortality rates.

Effects of home disease management strategies based on the dyadic illness management theory on elderly patients with chronic heart failure and informal caregivers’ physical and psychological outcomes: protocol of a randomized controlled trial

BackgroundCurrently, most elderly chronic heart failure (CHF) patients go home for rehabilitation after certain treatment in hospitals. However, the results of their rehabilitation at home are not satisfactory. According to studies, dyadic treatments can increase the efficiency of home rehabilitation, enhance both partners' quality of life, lessen the caregiver's load of care, and alleviate the strain of medical resources. Thus, the aim of our research is to design a study protocol that included elderly CHF patients and their informal caregivers as an intervention unit and to explore the impact of the protocol on their health and physical outcomes.MethodsThis is a prospective randomized controlled trial conducted in a triple-A hospital. In total, 80 elderly CHF patients and informal caregivers (80 dyads) will be recruited with informed consent. Based on the randomized numbers, they are divided into a control group (40 dyads) and an intervention group (40 dyads), subjects in the control group will receive usual care, and subjects in the intervention group will receive a home-based disease management program based on the Theory of Dyadic Illness Management on the basis of the control group. The duration of the intervention is 3 months, and the follow-up is 6 months. Data is collected at enrolment, 3 months after the intervention, and 3 months after the end of the intervention. The primary outcome is patients’ quality of life and readmission. Secondary outcomes include patients’ self-management behaviors, anxiety, and depression and caregivers’ quality of life and care burden.DiscussionThis study focuses on whether this home-based disease management program can improve the quality of life of elderly patients with CHF, reduce the readmission rate, enhance their self-management capacity, reduce negative emotions, and reduce the burden of informal caregivers. It can provide a new perspective on home management and cardiac rehabilitation of heart failure disease in the elderly, as well as alleviate problems such as the burden of healthcare resources.Trial registrationChinese Clinical Trials Registry ChiCRT2300068026.

Does Hospital–Physician Integration Improve Hospital Performance? Results from a USA Longitudinal Study

In a dynamic healthcare industry, aligning the goals and objectives of hospitals and physicians through integration has been suggested to influence performance. Physicians’ leadership and active involvement in governance can direct resource usage, Electronic Health Record (EHR) implementation, price negotiation, better coordination, and continuity of services for patients, thus affecting performance. This study aimed to examine the relationship between physician integration and hospital performance, investigating both financial and quality outcomes. We used a longitudinal study design. Our sample was hospital-level data from 2014 to 2019, which contained 6000 U.S. hospital-year observations. The dependent variables were quality outcomes (readmission rates) and financial outcomes (total and operating margins). The independent variable explored three dimensions of integration: high, low, and overall integration. Findings showed no impact of hospital–physician integration on quality outcomes and financial performance. High-integration hospitals did not show any significant relationships with quality outcomes and financial performance compared to hospitals that did not have high integration. Hospital–physician integration may have little potential to bring clinical integration even though vertical integration is present. A commitment to improving quality as a strategic priority may be vital in impacting quality outcomes, followed by financial performance.

Comparison of postoperative bleeding in pediatric tonsillectomy versus tonsillotomy

ObjectiveTonsillar surgery is a common intervention for pediatric obstructive sleep apnea and recurrent tonsillitis. This study compared postoperative bleeding incidence and severity following tonsillotomy and tonsillectomy at a single medical center. Study designA retrospective cohort study on 1984 pediatric patients (1–18 years old) who underwent surgery during 2004–2011 and 2019–2022. Tonsillectomy was performed during 2004–2011, while tonsillotomy was preferred for obstructive sleep apnea during 2019–2022. Tonsillectomy was performed using cold steel technique with complete removal of tonsillar tissue, while tonsillotomy was conducted using mono- or bipolar diathermy, preserving minimal tissue on the tonsillar capsule. SettingShaare-Zedek Medical Center, Faculty of Medicine, Hebrew University. MethodsOutcome measures included postoperative bleeding incidence and severity, surgery duration, hospitalization length, and readmission. ResultsTonsillotomy was conducted on 958 (48.3 %) patients, and tonsillectomy was performed on 1026 (51.7 %) patients. Obstructive sleep apnea was the only indication in 1553 (78.3 %) patients. Overall bleeding rate was lower following tonsillotomy (3.9 %) than tonsillectomy (9.5 %) (p < 0.001). Significantly more patients required surgical bleeding control post-tonsillectomy than post-tonsillotomy: 39 (3.7 %) vs. 5 (0.5 %), respectively (p < 0.001). Tonsillectomy resulted in higher readmission rates (11.8 % vs 6.1 %, p < 0.001), more blood transfusions (3 vs. 0), and higher postoperative hemoglobin diminution (1.57 ± 2 vs. 0.94 ± 1 g/dL, p = 0.035). The duration of the surgery was shorter for tonsillotomy (24.7 vs 26.5 min, p = 0.012). Tonsillectomy sustained higher bleeding rates for obstructive sleep apnea patients (7.0 % vs 3.9 %, p = 0.006). For recurrent tonsillitis patients, bleeding rates did not vary between year groups. Older age and tonsillectomy were the most significant risk factors for postoperative bleeding. ConclusionAmong children undergoing tonsillar surgery for obstructive sleep apnea, tonsillotomy was associated with a safer postoperative bleeding profile, reduced bleeding severity, and fewer readmissions compared to tonsillectomy.

Development and transfer learning of self-attention model for major adverse cardiovascular events prediction across hospitals

Predicting major adverse cardiovascular events (MACE) is crucial due to its high readmission rate and severe sequelae. Current risk scoring model of MACE are based on a few features of a patient status at a single time point. We developed a self-attention-based model to predict MACE within 3 years from time series data utilizing numerous features in electronic medical records (EMRs). In addition, we demonstrated transfer learning for hospitals with insufficient data through code mapping and feature selection by the calculated importance using Xgboost. We established operational definitions and categories for diagnoses, medications, and laboratory tests to streamline scattered codes, enhancing clinical interpretability across hospitals. This resulted in reduced feature size and improved data quality for transfer learning. The pre-trained model demonstrated an increase in AUROC after transfer learning, from 0.564 to 0.821. Furthermore, to validate the effectiveness of the predicted scores, we analyzed the data using traditional survival analysis, which confirmed an elevated hazard ratio for a group with high scores.

The 30-day readmission rate of patients with an overlap of probable sarcopenia and malnutrition undergoing major oncological surgery.

Overlapping sarcopenia and malnutrition may increase the risk of readmission in surgical oncology. Overlapping probable sarcopenia/malnutrition was found in 4.6% of 238 patients and the 30-day unplanned readmission rate was 9.0%. In multivariate analysis, the overlap of probable sarcopenia and malnutrition was a significant predictor for the 30-day unplanned readmission (OR= 8.10, 95%CI= 1.20-0.55; p=0.032). ■ Probable sarcopenia plus malnutrition was significantly associated with unplanned readmission. ■ Overlap of probable sarcopenia and malnutrition was an independent risk factor for readmission. ■ Certification of whether the patient is malnourished and/or sarcopenic preoperatively is necessary. ■ SARC-F and subjective global assessment can effectively and easily assess sarcopenia and malnutrition at admission. To assess the 30-day unplanned readmission rate and its association with overlapping probable sarcopenia and malnutrition after major oncological surgery. A prospective bicentric observational cohort study performed with adult oncological patients undergoing major surgery. The primary outcome was unplanned readmission within 30 days after discharge and the association with probable sarcopenia and malnutrition. Nutritional status and probable sarcopenia were assessed just prior to surgery. Patients classified using subjective global assessment, as B and C were malnourished. Probable sarcopenia was defined using SARC-F (strength, assistance with walking, rise from a chair, climb stairs, falls) questionnaire ≥4 points and low HGS (handgrip strength) <27kg for males and <16kg for females. Two hundred and thirty-eight patients (51.7% female) with a median age of 60 years were included. The 30-day readmission rate was 9.0% (n=20). Univariate analysis showed an association of malnutrition (odds ratio (OR) = 4.84; p=0.024) and probable sarcopenia (OR = 4.94; p=0.049) with 30-day readmission. Furthermore, when both conditions were present, the patient was almost nine times more likely to be readmitted (OR = 8.9; p=0.017). Multivariable logistic regression analysis showed that overlapping probable sarcopenia and malnutrition was an independent predictor of 30-day unplanned readmission (OR = 8.10, 95% confidence interval (95%CI) 1.20-0.55; p=0.032). The 30-day unplanned readmission rate was 9.0%, and the overlap of probable sarcopenia and malnutrition is an independent predictor for the 30-day unplanned readmission after major oncologic surgery.

8152 Benefits of Inpatient Diabetes Management by a Specialized Diabetes Team

Abstract Disclosure: M. Bojarian: None. A. Ohri: None. C. Buettner: None. Background: Inpatient dysglycemia is associated with poor clinical outcomes such as prolonged length of stay (LOS), increased risk of ICU admission, and in-hospital mortality. The benefits of managing diabetic patients in the hospital with a dedicated diabetes team, as opposed to standard care on episodes of hypoglycemia or hyperglycemia, reduction in LOS, and 30-day readmission rates, remain uncertain. A potential confounder is the likelihood that patients receiving a diabetes consult may be sicker than those without a consult. Given the growing evidence supporting the role of specialized diabetes teams in improving care for diabetes patients, we sought to examine these benefits at our hospital. We plan to address confounding variables through propensity score matching. Objective: To assess whether diabetes patients experience reduced LOS, hypoglycemia, hyperglycemia, and 30-day readmission rates when managed by a specialized diabetes team compared to inpatients managed by a hospitalist team. Material and Methods: This quality improvement study compared LOS, hypoglycemia (glucose &amp;lt;70 mg/dL), hyperglycemia (glucose &amp;gt;180 mg/dL), and 30-day readmission rates in diabetes patients managed by a specialized diabetes team versus a hospitalist team at our hospital between June 2022 and December 2022. Results: 5676 patients with diabetes were admitted between June and December 2022 at our hospital, and a specialized diabetes team managed 417 patients (7.34%). In a preliminary analysis in which no propensity matching was performed yet, the 30-day readmission rate was significantly lower (87,16.6%) in patients who received a diabetes consult compared to patients who did not receive a diabetes consult (320,17.9%). The rate of hypoglycemia was higher (24.4%) in the specialized diabetes consult group than in the non-diabetes consults group (19.9%). Additionally, LOS was longer in patients with a specialized diabetes consult (7.1 vs. 3.1 days), and hyperglycemia (glucose &amp;gt;180 mg/dL) was more prevalent in the specialized diabetes consult group (78.9%) compared to the non-diabetes consult group (39.2%). Conclusion: In this retrospective analysis, patients managed by a specialized diabetes team showed lower readmission rates despite longer hospitalization and increased dysglycemic episodes. This could be attributed to sicker patients receiving diabetes consults, influencing dysglycemia rates. To account for such confounders, ongoing propensity score matching aims to provide a clearer understanding. Reduced readmission rates suggest improved care transitions, potentially resulting in significant cost savings for the healthcare system. Presentation: 6/1/2024

6479 Acute Estradiol and Progesterone Therapy In Hospitalized Adults With Moderate COVID-19: A Randomized Control Trial

Abstract Disclosure: D. Lovre: Research Investigator; Self; Novo Nordisk, Corcept Therapeutics. K.M. Bateman: None. L.Y. Saltzman,: None. M. Qadir: None. F. Mauvais-Jarvis: None. Background and Objective: COVID-19 outcomes are less severe in women vs men. Experimental studies show that estradiol (E2) and progesterone (P4) produce anti-inflammatory immune responses and immune tolerance and enhance antibody production. The effect of E2 and P4 combination on COVID-19 severity is unknown. The aim of the study was to evaluate the efficacy of a short systemic E2/P4 combination in mitigating COVID-19 severity in hospitalized men and women. Methods: Phase 2, double blind, placebo-equivalent controlled, single center trial of ten participants (men and women) who were hospitalized for COVID-19, with scores 3 to 5 on the 9-point World Health Organization (WHO) ordinal scale for clinical improvement. Participants were randomized into two arms and treated for five days: 1) E2 Cypionate (5 mg IM once) and micronized P4 (200mg, PO daily); and 2) Placebo-equivalent (normal saline (1ml, IM once) and folate (400mcgs, PO daily), in addition to standard of care (SOC). The primary outcome was the proportion of patients improving to scores 1 or 2 on the WHO scale on the day of discharge. Secondary outcomes included length of hospital stay (LOS), days on oxygen therapy (DOT), readmission rates (RR), adverse events (AEs) and change in inflammatory biomarkers assessed by untargeted proteomics. Findings: There were no significant differences between the treatment groups in COVID-19 severity by WHO score, LOS, DOT, RR or AEs. Patients in the E2/P4 arm exhibited a decrease in inflammatory biomarkers of respiratory and gastrointestinal disease (GI) and significant change in immune and inflammatory responses. Conclusions: Use of short-term systemic E2/P4 is associated with decrease in biomarkers of respiratory and GI disease inflammation and change in biomarkers of immune and inflammatory response.

6909 Mortality and Readmission Rates for Inpatients with Diabetic Foot Ulcer in a Tertiary, Urban Medical Center: A Five-Year Retrospective Review

Abstract Disclosure: A. Herrera Chancay: None. R. Lopez Fanas: None. H. Tabassum: None. J. Daily: None. A. Myers: None. Background: Diabetic Foot Ulcer (DFU) is a severe complication of diabetes mellitus and is associated with high rates of morbidity and mortality. The incidence of DFUs and amputation disproportionately impact Black and Hispanic populations. DFU is also associated with a high rate of hospital readmissions and prolonged length of stay (LOS). The goal of this study was to examine 1-year mortality data, LOS and readmission rate. Methods: This study was a retrospective chart review of 1348 patients admitted to three hospitals in our system in the Bronx from 6/1/16 to 5/31/21. Data was extracted from the EPIC® electronic health records, based on the diagnoses ICD 10 codes, E10.621 and E11.622. Inclusion criteria was patients admitted with an active DFU regardless of other admission diagnosis, age 18 years or above. The index admission was defined as the first admission in our medical records within the date range. Patients were excluded if their index admission was not accessible through our EMR. Simple logistic regression and multiple logistic regression were used to analyze the association between variables of interest and mortality at index admission and at 1-year, LOS and re admissions. Results: Of the 650 eligible patients, the mean age was 59 + 13 years, 70% of patients were male, and majority were non-White (88%). Mortality was 1% during the index admission and the risk increased to 6% at 1 year after the index admission. Readmission with an active DFU from the index admission occurred in 15% of patients within 30-days, 32% of patients within 90 days, and 55% of patients within 1 year. The mean length of stay was 9 +7.5 days. Discussion: Our study in an urban region has identified high rates of mortality and costs associated with DFU, which has been reported in many settings. This patient population is high risk for poor outcomes and targeted programs are needed to reduce mortality and provide care to reduce readmissions. Future studies that explore the challenges of DFU health care and that test interventions are needed to improve DFU related health outcomes. Presentation: 6/2/2024

7481 Beyond the Operation Room: A Retrospective Study on Diabetes and Post-Operative Hyperglycemia Outcomes

Abstract Disclosure: P. Aron: None. T. Zaihra Rizvi: None. M. Hodge: None. J. Upadhyay: None. Introduction: Optimal, evidence based intraoperative and postoperative glycemic management may reduce poor surgical outcomes. Research design: This is a retrospective study from a single center to estimate quality gaps in perioperative glycemic management in patients with diabetes undergoing major surgery requiring general anesthesia between Oct 2022 and Dec 2022. Study Cohort: Patients &amp;gt; 18 years old, who underwent major surgery (&amp;gt;3 hrs) under general anesthesia, had diabetes mellitus based on Hba1c &amp;gt; 6.5% within last 1 year or as listed diagnosisThis is an ongoing study. We have currently looked at 79 patients of which 61 were in the hyperglycemic group (glucose &amp;gt; 180 mg/dL) and 18 in normoglycemic group (glucose &amp;lt; 180mg/dL) post-operatively. Methods: Baseline characteristics, perioperative outcomes, and operative details between the hyperglycemic and normoglycemic groups were compared using Kruskal-Wallis's rank sum test for continuous variables and χ2 or Fisher's exact tests using categorical variables. Results: Patients who were found to have hyperglycemia in the first 24 hours after surgery had a higher preop A1c of 7.4% vs 6.7% in the normoglycemia group (p-value = 0.047). They also had a higher BMI of 32 as compared to 30 respectively and a reduced GFR of 60 vs 73 in the normoglycemic group (P=0.069). 24 hours leading into surgery, the hyperglycemia group had a high average glucose of 196 mg/dL as compared to 135 mg/dL (p-value = 0.001). During the intraoperative period which lasted on average of 350 minutes (5.5 hours) there was an average glucose check of 3.2 times averaging 221 mg/dL for the hyperglycemia group compared to 2.2times averaging 174 mg/dL (P = 0.017). 62% of patients with intraoperative hyperglycemia DIDNOT receive IV insulin treatment in the hyperglycemic group. Steroid use was equal in both groups. 24 hours after surgery, patients in the hyperglycemia group had an average glucose reading of 252 mg/dL compared to 145 mg/dL in the normoglycemia group (P &amp;lt; 0.001).Endocrinology was not consulted in 87% of patients with hyperglycemia. Looking at our endpoints, readmission rate was 23% in the hyperglycemia group as opposed to 11% in normoglycemia. There were 4 patients who had a 90-day mortality from the hyperglycemia group compared to no patients in normoglycemia. 37% of patients had post-op complications in the hyperglycemia vs 22% in the euglycemia group (P 0.269). The hospital stay was the same for both groups averaging 8 days. Conclusions: Intraoperative hyperglycemia leads to poor outcomes.

Context: A Fracture Liaison Service (FLS) provides an important mechanism to address vitamin D deficiency (VDD) which is commonly found in patients hospitalized with a fragility fracture. Objectives: To study the prevalence of VDD and its associated clinical outcomes among patients hospitalized for osteoporotic fracture. To explore inpatient strategies of vitamin D repletion in the immediate post fracture setting. Design, Setting and Patients: An observational study of patients admitted to the Massachusetts General Hospital (MGH) with fractures between January 2016 to October 2023 who were cared by the FLS. Exposures and Intervention: A vitamin D repletion regimen consisting of ergocalciferol 50,000 international units (IU) oral daily for a number of days followed by maintenance cholecalciferol of 1000-1500 IU daily was studied in a subset of patients with VDD. Main Outcomes and Measures: Prevalence of VDD among MGH FLS patients. Efficacy of inpatient daily ergocalciferol administration to raise serum 25OHD. Results: Of the 2,951 consecutive patients, 724 (24.53%) were vitamin D deficient as defined by serum 25OHD level of ≤19ng/ml. Men (252 of 897, or 28.09%) were more likely than women (472 of 2,054, or 22.98%) to have VDD (p = 0.003). VDD was seen 41.79% (117 of 280), 24.41% (332 of 1,360) and 20.98% (275 out 1,311) of patients of ≤59, 60-79, and ≥80 years old, respectively (p &amp;lt; 0.00001).Of the 1,303 patients with hip fragility fractures, 327 (25.09%) had VDD. Patients with VDD, despite being younger (78.55±11.75 vs. 80.28±10.47, p=0.018), had longer average length-of-stay (aLOS) than those without VDD did (8.37±7.35 vs. 7.23±4.78 days, p=0.009). Re-admission and non-union rates up to two years following the index hip fracture were not different between the two groups.Among 32 patients, without known malabsorption or liver cirrhosis, who had 25OHD levels available before and after ergocalciferol treatment, each dose of ergocalciferol, on average, raised serum 25OHD by 3.62±2.35 (m±sd) ng/ml. Daily ergocalciferol administration did not change serum calcium and creatinine levels.Patients with chronic liver disease (CLD), who had higher prevalence of VDD (64 of 156 patients, or 41.04%), showed impaired per-dose-of-ergocalciferol 25OHD response (0.87±0.92. n=10) ng/ml. Conclusions and Relevance: Nearly 25% of patients hospitalized for osteoporotic fractures, cared for by MGH FLS, had VDD. Male sex, younger age, and CLD were associated with a higher prevalence of VDD. VDD was associated with, on average, one extra day of hospital stay among patients admitted for hip fracture. Daily ergocalciferol, with each dose of 50,000 IU raising serum 25OHD level by 3-4 ng/ml, followed by maintenance dose of cholecalciferol of 1000 to 1500 IU is potentially a practical way to quickly replete vitamin D among patients with VDD hospitalized for fracture.

12397 Predictors Of Hospital Readmission Within Three Months Among Patients Admitted For Diabetic Ketoacidosis (dka)

Abstract Disclosure: O. Onwudiwe: None. L. Yerashevich: None. C. Onwudiwe: None. B. Baral: None. A. Acharya: None. H. Nguyen: None. Purpose: Diabetic ketoacidosis (DKA) represents a critical, life-threatening complication of diabetes, with higher rates of re-admission noted among individuals from lower socioeconomic backgrounds, those lacking insurance coverage, and those with suboptimal follow-up care. This study seeks to identify predictors of hospital readmission within three months among patients admitted for DKA in a community hospital setting. Methods: Patient data were extracted from electronic medical records from 2019 to 2021 for individuals admitted due to DKA using ICD codes. DKA diagnosis was based on the presence of hyperglycemia, high anion gap metabolic acidosis, and ketonemia. Demographic information, results of routine biochemical tests, insurance status, follow-up with primary care providers (PCP) or endocrinologists, and clinical progression were retrospectively collected from patients' records. Multivariable logistic regression analyses were conducted to identify predictors of readmission. Results: A total of 222 unique DKA admission visits were analyzed. The mean age (standard deviation) of the patients was 48 (16) years, and 58% of them were male. Among these visits, 39% had type 1 diabetes, 43% had type 2 diabetes, and 18% were newly diagnosed diabetes cases. The majority of patients were overweight, with a mean body mass index (BMI) of 27, and the mean glycated hemoglobin level was 10.8. Common triggers for DKA included insulin non-adherence (52%), infection (37.8%), and alcohol use (8.6%). Logistic regression analysis revealed that lack of follow-up significantly increased the odds of readmission within three months (B = 2.025, p = .003, Exp(B) = 7.576, 95% CI [1.952, 29.401]), as did having type 1 diabetes (B = 1.473, p = .019, Exp(B) = 4.364, 95% CI [1.272, 14.978]). However, the association between insulin adherence and readmission was not statistically significant at the conventional alpha level of 0.05 (B = 1.329, p = .112, Exp(B) = 3.777, 95% CI [0.733, 19.458]). Other demographic (age, gender, employment status, insurance status, medication compliance,) and clinical [insulin adherence, presence of infection, blood glucose level at diagnosis of DKA, and level of glycated hemoglobin (Hba1c)] variables did not significantly predict readmission within 3 months. Conclusion: DKA, being preventable with adequate insulin adherence, is also influenced by factors such as infection and lifestyle choices. The findings highlight the critical role of post-discharge follow-up care in reducing readmission rates among DKA patients. Healthcare providers should prioritize ensuring timely and comprehensive follow-up, particularly for patients with type 1 diabetes, to optimize post-hospitalization management and prevent avoidable readmissions.

7555 Gender-Related Differences in Outcomes of Patients With Diabetic Ketoacidosis: An Analysis of the National Readmission Database

Abstract Disclosure: E. Ahsan: None. C. Lesniak: None. M. Akula: None. K. Hu: None. K. Chalasani: None. R. Ong: None. S. Holland: None. M. Hossain: None. J. Cheng: None. J. Heaton: None. Introduction: Diabetic ketoacidosis (DKA), one of the most serious complications of diabetes, is a significant cause of morbidity and mortality. Hospitalizations for DKA have increased significantly over the past two decades. Despite this, there is a notable absence of data on gender-related variations in the clinical characteristics and outcomes of individuals hospitalized with DKA. Understanding these distinctions is crucial for optimizing disease prevention and care. Thus, the primary aim of this study was to explore whether gender influences the outcomes of DKA. Methodology: We analyzed the National Readmissions Database (NRD) from 2016 to 2020 by evaluating patients admitted with a primary diagnosis of DKA without coma. Patients were included if they were at least 18 years old and admitted between January and November. Patients meeting inclusion criteria were stratified by sex. The groups were assessed for 30-day readmissions, all causes of mortality, length of stay, and total cost. Descriptive statistics, Cox proportional hazards, and adjusted Wald tests were used to compare the groups. Results: Between 2016 and 2020, 642,431 patients met the inclusion criteria with a median age of 44, of which 46.5% were female and 53.5% were male. Early readmission occurred in 33,639.20 females and 31,101.92 males. Cox regression analysis showed a significant difference in readmission risk for female patients than males (HR 1.20, 95% CI 1.17-1.22, P = &amp;lt;0.001). The length of stay was higher in male patients than in female patients (adjusted Wald test, P =&amp;lt;0.001). Inpatient mortality was higher in females than in males (Cox regression analysis, P = 0.009). Total cost was higher in males compared to females (adjusted Wald test, P = &amp;lt;0.001). Conclusion: Regrettably, the majority of studies on diabetic ketoacidosis (DKA) have not given due attention to gender differences. Our study, however, reveals statistically significant variations in in-hospital mortality and 30-day readmission rates between men and women hospitalized with DKA, with women exhibiting higher rates than men. Additionally, the length of stay and total cost were found to be higher for men. To comprehend the underlying reasons for these distinctions, further investigations are warranted. Early introduction and intensification of insulin therapy may prove beneficial for this patient group in mitigating the risk of DKA and other complications associated with diabetes mellitus.

Inferior Glenoid HyperOSTosis (GHOST) Lesion Development Following Reverse Total Shoulder Arthroplasty

BackgroundPatients undergoing reverse shoulder arthroplasty (RTSA) have been noted on postoperative radiographs to have a curved bony overgrowth on the inferior glenoid neck. This study aims to investigate potential risk factors for and postoperative effects of these ossifications, here called glenoid hyperostosis (GHOST) lesions due to their location. MethodsA retrospective review of patients undergoing reverse total shoulder arthroplasty between 2007 and 2020 at a single institution was performed. Predictors including gender, age, implant sizing, and preoperative diagnosis were examined using logistic regression analysis. Outcomes including readmission rate, revision rate, preoperative and postoperative range of motion, visual analog scale (VAS) pain scores, and American Shoulder and Elbow Surgeons (ASES) functional outcome scores were also analyzed using two-sample t-tests. ResultsPreoperative and postoperative radiographs of 170 primary reverse shoulder arthroplasty patients were assessed. 25.9% of RTSAs were identified to have a GHOST lesion. When adjusting for race, age, BMI, preoperative diagnosis, male patients were still associated with 2.28 odds of developing a GHOST lesion compared to female patients (95% CI: 1.08 – 4.86). Other elements such as age, race, BMI, laterality, preoperative diagnosis, implant manufacturer, and implant sizing demonstrated no statistically significant association to GHOST lesion presence. Postoperatively, GHOST lesion development was not associated with range of motion or ASES score. However, presence of GHOST lesions on radiographs was associated with increased pain scores for patients at 2 months (p = 0.034) and 12 months (p = 0.029) postoperatively. DiscussionInferior glenoid hyperostosis (GHOST) lesions is a common and potentially benign finding following reverse shoulder arthroplasty, with unclear etiology. Risk factors for GHOST lesions included male gender, while patient demographics, implant type or size, shoulder lateralization and distalization were not associated with lesion formation. Clinically, greater short-term VAS scores were seen in patients with GHOST lesions. However, there were no differences observed between the two groups in ASES scores or postoperative range of motion at later time points. Further research is needed to identify risk factors and assess the clinical implications of GHOST lesions.
