Frailty in patients with IDH-mutant gliomas: experience from a high-volume tumor center.

Gliomas are increasingly diagnosed in an aging population, with treatment outcomes influenced by factors like tumor genetics and patient frailty. This study focused on IDH-mutant gliomas and assessed how frailty affects 30-day readmission and overall survival (OS). We aimed to address a gap in understanding the impact of frailty on this specific glioma subtype. 136 patients with an IDH-mutant glioma between 2007 and 2021 were identified at our institution. High frailty was classified by scores ≥ 1 on the 5-factor modified frailty index (mFI-5) and ≥ 3 on the Charlson Comorbidity Index (CCI). Patient and tumor characteristics including age, sex, race, Karnofsky Performance Status (KPS), Body Mass Index (BMI), tumor type and location, type of operation, and therapy course were recorded. Outcomes measured included 30-day readmission and overall survival (OS). Analysis was conducted utilizing logistic regression and Kaplan-Meier curves. Of the 136 patients, 52 (38%) had high frailty: 18 with CCI ≥ 3, 34 with mFI-5 ≥ 1. High frailty correlated with increased BMI (CCI: 30.2, mFI-5: 30.1kg/m2), more neurological deficits (CCI: 61%, mFI-5: 56%), and older age at surgery (CCI: 63, mFI-5: 48years). Hospital readmission within 30days occurred in 8 (5.9%) patients. Logistic regression indicated no significant difference in 30-day readmission rates (CCI: p = 0.30, mFI-5: p = 0.62) or median OS between high and low frailty groups. However, patients treated at our institution with newly diagnosed tumors with high mFI-5 had a 6.79 times higher adjusted death hazard than those with low mFI-5 (p = .049). Our analysis revealed that CCI and mFI-5 were not significantly associated with 30-day nor OS. However, in patients with non-recurrent tumors, there was a significant association of mFI-5 with OS. Further study of frailty with larger cohorts is warranted to enhance prognostication of outcome after neurosurgical treatment.

Impact of a general medicine consultant-led ward round in the emergency department.

Patients requiring admission to the general medicine wards in a public hospital are usually assessed by a medical registrar. This study is based at a metropolitan public hospital in Melbourne where the majority of general medicine patients in the emergency department (ED) are not seen by a consultant physician until they are transferred to the ward. To assess the impact of general medicine consultant-led ward rounds (CWRs) in the ED on patient length of stay (LOS). One-month audit was conducted of all patients admitted to general medicine and awaiting transfer to ward from ED at a metropolitan public hospital in Melbourne. A general medicine CWR was then implemented in the ED, followed by another 1-month audit, with the primary outcome being LOS and the secondary outcome being 30-day readmission rate. Additionally, admitting medical registrars were invited to complete a survey before and after the implementation of CWRs to assess satisfaction rate. Data from electronic medical records were analysed for 162 patients (90 preimplementation group and 72 postimplementation group). The median LOS was 6 days in the preimplementation group and 4 days in the postimplementation group (P = 0.014). There was no significant difference in 30-day readmission rates. Surveys showed admitting medical registrars reported a reduced level of stress and fewer barriers to seeking consultant input following implementation. A CWR in the ED has led to decreased LOS for general medicine patients and improved satisfaction among junior medical staff.

Comparison of 2 Models of Care for Children With Medical Complexity Following Spinal Fusion.

We conducted a retrospective chart review of patients with neuromuscular scoliosis following spinal fusion surgery who were cared for post-operatively by either a hospitalist/orthopedics co-management team or a complex care clinic (CCC). Assignment to either treatment group was not random. To account for baseline differences between groups, we calculated propensity scores and used these as probability weights in generalized linear models. After matching, the CCC had a shorter length of stay (LOS, coefficient = -2.60; P = .04) without a significant difference in 30-day readmission rate (P = .62). For secondary outcomes, there were some significant resource utilization benefits favoring the complex care group without significant difference in complication outcomes between groups. In managing patients after spinal fusion surgery, both groups had similar LOS compared with prior studies of children after spinal fusion surgery. Management by the CCC may confer some outcome benefits for their patients.

Outcomes of a same day discharge protocol in patients undergoing mastectomy and implant reconstruction.

Finite hospital resources has required a closer look at resource allocation. This has prompted a shift toward same day surgeries and a focus on reducing hospital readmissions. Following the institution of a same day discharge protocol for mastectomy and mastectomy with immediate reconstruction, we sought to assess differences in the length of stay and readmission rates. This retrospective review evaluates all cases of mastectomy with or without immediate reconstruction performed at a single high-volume center between June 2019 and March 2021. Average length of stay, 30-day readmission rates, Anesthesia Society Assessment class, and type of immediate reconstruction were assessed. Autologous reconstructions were excluded. A total of 413 patients underwent mastectomy with or without reconstruction (n=148 pre protocol and n=265 during protocol) between June 2019 and March 2021. Of those 413 patients, 180 underwent reconstruction (n=62 pre protocol and n=118 during protocol). The average length of stay after mastectomy following the implementation of the same day discharge protocol was decreased at 0.6days (n=265) compared to preimplementation at 1.02days (n=148), p<0.001. The 30-day readmission rate was not significant between the groups, p=0.13. A total of 180 patients underwent immediate reconstruction after mastectomy. The average length of stay after mastectomy with immediate reconstruction following implementation of the same day discharge protocol was shorter than preimplementation at 1.05days preimplementation (n=62) versus 0.58days following implementation (n=118), p<0.001; this finding was significant for both prepectoral and subpectoral implants, p<0.001. There was no significant difference in 30-day readmission rates between the groups with immediate reconstruction, p=0.34. Same day discharge for mastectomy with reconstruction is as safe as the more widely recognized same day discharge practice for patients with mastectomy alone.

Effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer: a systematic review and meta-analysis.

To evaluate the effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer. We conducted a systematic search of the PubMed, Embase, CINAHL, Web of Science, and Cochrane Library (CENTRAL) databases from database inception to May 5, 2023, for randomized controlled trials (RCTs) and cohort studies that investigated prehabilitation in the context of esophagogastric cancer. A random-effects model wasusedformeta-analysis. We identified 2,994 records and eventually included 12 studies (6 RCTs and 6 cohort studies) with a total of 910 patients. According to random-effects pooled estimates, prehabilitation reduced the incidence of all complications (RR = 0.79, 95% CI: 0.66 to 0.93, P = 0.006), pulmonary complications (RR = 0.61, 95% CI: 0.47 to 0.79, P = 0.0002), and severe complications (RR = 0.63, 95% CI: 0.47 to 0.84, P = 0.002), and shortened the length of stay (MD = -1.92, 95% CI: -3.11 to -0.73, P = 0.002) compared to usual care. However, there were no statistically significant differences in 30-day readmission rates or in-hospital mortality. Subgroup analysis showed that multimodal prehabilitation was effective in reducing the risk of all complications and severe complications, while unimodal prehabilitation was not. Our findings suggested that prehabilitation may be beneficial in reducing postoperative complications and length of stay. We recommend preoperative prehabilitation to improve postoperative outcomes and hasten recovery following esophagogastric cancer surgery, and multimodal prehabilitation seems to be more advantageous in reducing complications. However, further studies are needed to confirm these results.

Telehealth Pharmacist Approach to Comprehensive Medication Management in Post-Discharge High-Risk Patients: A Quality Improvement Initiative.

Introduction: Clinical Pharmacist-led Comprehensive Medication Management (CMM) has the potential to mitigate medication errors during transitions in care, but current evidence is underdeveloped. The objective of this work was to assess the impact of optimized CMM services through a telehealth pharmacist clinic on hospital readmission and Emergency Department (ED) utilization rates. Methods: A quality improvement study with patients discharged home from an urban, nonacademic Hospital in Westchester County, New York, receiving telehealth CMM was used. Participants included adult patients discharged home from an internal medicine unit considered high risk for preventable adverse medication errors based on comorbidities and prescribed medications. Eligible patients were offered to enroll in telehealth CMM visits with a clinical pharmacist immediately, 30 days, and 60 days post-discharge versus the current standard of care. Results: Primary outcomes included the impact on 30- and 90-day readmission and ED visit rates. Secondary outcomes included quantifying the outcomes on patient engagement, enrollment, and volume resulting from the program's process improvements. In this study, 3,060 patients were discharged from June 14, 2021, to May 10, 2022; 1,547 were eligible and offered CMM visits, and 889 completed enrollment (Treated). There was a 2.1% absolute difference in 30-day readmission rates between untreated and attempted (p = 0.07), and a 2.9% difference between the untreated and treated group (p = 0.04). Thirty-day ED utilization decreased by 1.6% between untreated and attempted (p = 0.3), and 3.5% between the untreated and treated (p = 0.03). There were four Plan-Do-Study-Act cycles in this program, in which the process improvements resulted in an overall average increase in patient volume, enrollment rates, and patient engagement for this QI initiative. Conclusions: This study yielded significant reductions in readmission and ED utilization rates among treated patients, highlighting successful process improvements that improved patient engagement and the potential for enhancing care coordination in vulnerable populations.

Abstract 18362: Endovascular versus Surgical Revascularization for Chronic Limb Threatening Ischemia: A Comparison of Re-Admission Rates From NSQIP Database (2011-2021)

Background: Data regarding relative readmission rates following endovascular and surgical revascularization for chronic limb threatening ischemia (CLTI) are conflicting. Understanding comparative readmission rates may inform selection of the most appropriate revascularization modality for these patients. Research Question: What are the differences in 30-day readmission rates between endovascular and surgical interventions for CLTI? Methods: The 2012 to 2021 American College of Surgeons National Surgical Quality Improvement Program's (NSQIP) Targeted Vascular Module was used to identify patients discharged alive after surgical or endovascular revascularization for CLTI. The primary outcome was 30-day readmission following the index procedure; secondary outcomes included survival, major re-intervention of the treated arterial segment, amputation, untreated loss of patency of bypass graft, bleeding requiring transfusion or re-intervention, major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Revascularization modality was related to 30-day readmission using multivariable logistic regression. Results: We identified 30,390 patients (mean age 69±11.5 years, male 62.8%, mean BMI 26.9±8.1 kg/m 2 , 61% Caucasian, 20.2% Black). When compared with endovascular therapy, surgical bypass was associated with higher 30-day readmission (13.3% vs. 8.6%, p = &lt;0.001). After adjusting for demographic, clinical, procedural variables and year of publication, surgical revascularization was independently associated with higher 30-day readmission rates (OR 1.53 95% CI [1.36, 1.71]; p&lt;0.001), mortality and major reintervention rates (Figure). Conclusion: Surgical revascularization was independently associated with higher 30-day readmission rates when compared to endovascular revascularization for patients with CLTI.

Abstract 12814: Impact of Obesity on Catheter Ablation of Ventricular Tachycardia in the United States: In-Hospital and 30-day Outcomes

Background: Catheter ablation for ventricular tachycardia (VT) has been increasingly performed. While it is estimated that 42% of adults in the United States are obese, the impact of obesity on VT ablation procedures remains unclear. Objective: This study aimed to evaluate the procedural outcomes and 30-day readmission among non-obese and obese patients who underwent catheter ablation of VT. Method: Using the Nationwide Readmissions Database, our study included patients aged 18 years or older who underwent catheter ablation for VT between 2017 and 2020. The study cohort was stratified into non-obese (BMI &lt; 30kg/m 2 ) and obese (BMI ≥ 30kg/m 2 ). The in-hospital procedural outcome and 30-day readmission were analyzed between these groups. Results: Our study included a total of 835 obese patients (19.7%) and 3393 non-obese patients (80.3%). Obese group had a higher rate of prolonged length of stay (&gt;7 days) (37.6% vs 31.2%, p&lt;0.01) and a higher cost of hospitalization ($39 983 vs $37 015, p&lt;0.01). Overall, there were no significant differences in early mortality (4.5% vs 3.8%, p=0.45). Apart from increased vascular complications in the obese group (1.8% vs 0.9%, p=0.03), there were no significant differences in other procedural complications between both groups. There were no significant differences in 30-day readmission rates between obese and non-obese groups (15.5% vs 14.1%, p=0.38). Additional analysis performed in the obese group revealed a non-significant decreasing trend in early mortality rate post-procedurally (5.4% to 4.8%, P trend = 0.66). On multivariable analysis, heart failure was associated with a higher risk of 30-day readmission in obese patients (OR: 2.00; 95% CI: 1.01-3.99; p=0.05). Conclusion: Our study suggests that catheter ablation for VT can be performed relatively safely in obese patients without significant differences in 30-day mortality and readmission outcomes. Patients should not be excluded from VT ablation on the basis of obesity.

Modified Enhanced Recovery After Surgery (ERAS) Protocol Versus Non-ERAS Protocol in Patients Undergoing Emergency Laparotomy for Acute Intestinal Obstruction: A Randomized Controlled Trial.

Enhanced Recovery After Surgery (ERAS) is a multimodal approach with promising results in improving patient outcome. Only recently, is evidence emerging highlighting how similar principles of care can be applied to patients undergoing emergency abdominal surgery. A randomized controlled trial was conducted from November 2021 to April 2022 at PGIMER Chandigarh, which is a leading tertiary care hospital in northern India. 60 patients with acute intestinal obstruction requiring emergency laparotomy were randomized and assigned to ERAS or Non-ERAS group. ERAS protocol with some modifications was applied. Primary endpoints were post-operative hospital stay. Secondary end points were morbidity, 30-day readmission and mortality rate. Data analysis was done using SPSS 22.0. Independent t test or Mann-Whitney test and Chi-square or Fisher-exact test were used for analysis. A significant 3-day reduction in hospital stay was observed in ERAS compared to non-ERAS group (median (interquartile range) 5.50 (4.75-8.25) vs 8.0 (6.0-11.0) p = 0.003) with no difference in 30-day readmission rate, mortality rate and complication rate (according to Clavien-Dindo classification). ERAS group was associated with early recovery of gastrointestinal functions including time to first passage of flatus (p < 0.001), stools (p = 0.014), early ambulation (p < 0.001), time to first fluid diet (p < 0.001), solid diet (p = 0.001) and reduced nasogastric tube reinsertion rates (p = 0.01) despite its early removal. ERAS with some modifications can be applied in patients with intestinal obstruction. Thus, we can expedite post-operative recovery and early regain of gastrointestinal function with decreased hospital stay, comparable morbidity and mortality. Further studies are needed to assess ERAS role in emergency gastrointestinal surgeries. Trial registration Ctri.gov Identifier: CTRI/2022/04/042156.

Association between hospital admission either directly or via the emergency department, and readmission rates at 30days in older adults in two rural hospitals: a retrospective cohort study.

Older patients are frequently re-admitted to the hospital after attending the emergency department (ED). We investigated whether direct admission to the hospital was associated with a lower risk of readmission at 30days compared to admission via the ED, in patients aged ≥ 75years. Retrospective multicenter cohort study from 01/01/2018 to 31/12/2019, including patients aged ≥ 75years from two hospitals. Patients admitted directly were matched 1:1 with patients admitted via the ED for center, age category, sex, major diagnosis category, type of stay (medical/surgical), and severity. We compared readmission at 30days (primary outcome) and length of stay (secondary outcome) between groups. A total of 1486 matched patients with an available outcome measure were included for analysis. We observed no significant difference in 30-day readmission rate between those admitted directly (102/778, 13.1%) and those admitted via the ED (87/708, 12.3%, p = 0.63). There was a significant difference in length of stay between both groups: median 5days [Q1-Q3: 2-8] vs 6days [2-11] for direct and ED admissions, respectively (effect size: 0.11, p < 0.001). By multivariate analysis, only moderate to severe denutrition was associated with the risk of readmission at 30days (Odds Ratio 2.133, 95% Confidence Interval 1.309-3.475). The mode of entry to the hospital of patients aged 75years and older was not associated with the risk of readmission at 30days. However, those admitted directly had a significantly shorter length of stay than those admitted via the ED.

NATIONWIDE RISK OF READMISSION AND PATIENT ATTITUDE TOWARDS DAY-CASE TOTAL HIP ARTHROPLASTY

The interest in day-case hip arthroplasty is increasing; however, there are conflicting results regarding readmission risk, and little is known about patients’ attitude towards day-case surgery. We aimed to investigate differences in 30-day readmission rates between day-case patients and single-overnight-stay patients following total hip arthroplasty (THA) and explore patients’ attitude towards day-case surgery.From the Danish National Patient Register we identified 29,486 THAs (1353 day-case THAs and 28,133 single-overnight-stay THAs) performed between 2010 and 2020. Day-case surgery was defined as discharge on the day-of-surgery. Overnight admissions within 30 days of surgery were considered readmissions. Differences in readmission rates between day-case and single-overnight-stay patients were investigated using logistic regression adjusted for patient characteristics and year of surgery. In a single-center descriptive study, 2395 hip arthroplasty patients from 2016 to start-2023 answered a questionnaire on patient characteristics, attitude towards day-case surgery and patient-reported outcome measures (PROM).The overall 30-day readmission rate was 4.4% (CI: 4.2–4.6%) with no difference between day-case (4.4%) and single-overnight-stay THAs (4.4%) (odds-ratio: 1.2 [CI: 0.91–1.6]). In the descriptive study answers to the question whether patients were interested in being discharged on the day of surgery, were: “Yes” = 41%, “Do not know” = 20%, “No” = 39%. Patients responding “No” had lower preoperative PROM-scores, were older (“No” = 70.2 y vs. “Yes” = 65.3 y), and more often female (“No” = 72% vs. “Yes” = 52% female).Based on nationwide data from 2010–2020, day-case THA patients were not more likely to be readmitted compared to single-overnight-stay patients. However, most patients were not positive towards day-case surgery. While surgeons may consider day-case surgery to be safe, patients are not intuitively positive, indicating an attitude mismatch. To achieve high success rate and patient satisfaction in day-case surgery, shared-decision making initiatives within day-case surgery are needed.

Readmission and Disposition in Patients With Malignant Bowel Obstructions Following Gastrostomy Tube.

Patients with peritoneal carcinomatosis (PC) can develop malignant bowel obstructions (MBOs) requiring inpatient admission and nasogastric tube decompression. Palliative decompressive gastrostomy tubes (G-tubes) may affect patient disposition, allowing for self-management and reduction in inpatient services. Therefore, we sought to assess disposition and inpatient readmission rates in patients admitted with PC and MBO following G-tube placement. The Vizient® Clinical Data Base was queried for inpatient admissions from October 2018 to May 2022 utilizing ICD-10 codes to identify patients admitted with PC and bowel obstruction, with or without G-tube placement. Demographics and hospital outcomes were recorded. Descriptive statistics and multivariate logistic regression analysis were performed. From 750 patients, 59 (7.9%) had a G-tube placed. Compared to patients without G-tubes, those with G-tubes had lower rates of disposition to home (32.2% vs 70.0%, P < .001) and higher rates of disposition to hospice (home: 30.5% vs 7.8%, P < .001, facility: 10.2% vs 3.9%, P = .02). There was no significant difference in the rate (17.3% vs 22.3%, P = .40) or risk (OR = 1.44, 95% CI .69-3.01) of 30-day readmissions with G-tubes. However, palliative care consultation (OR 33.77, 95% CI 19.16-59.52) and G-tube placement (OR 5.82, 95% CI 2.56-13.25) were independent predictors for hospice. Placement of G-tubes in patients with PC and MBO was associated with higher rates of disposition to hospice but there is no difference in 30-day readmission rates compared to those without G-tubes. Further prospective studies are needed to understand the role of G-tube placement in patients with MBO in relation to outcomes and disposition.

Impact of Antimicrobial Stewardship Program Intervention Acceptance on Hospital Length of Stay.

Background: Inappropriate antibiotic use is a major public health concern. Excessive exposure to antibiotics results in the proliferation of multidrug-resistant bacteria, increase in potentially avoidable adverse drug reactions, healthcare utilization, and cost. Currently, systematic reviews and controlled trials assessing the effects of antimicrobial stewardship programs (ASP) on hospital length of stay (LOS), mortality, and cost-savings are conflicting. Some studies reported a significant cost-savings driven by shorter hospital LOS while the others found no effect and, in some cases, prolonged LOS. Shortening the time to appropriate therapy and reducing unnecessary days of therapy have been shown to reduce hospital LOS. Objective: The purpose of this study was to evaluate the effects of prescriber acceptance to ASP interventions on hospital LOS. Methods: Between January 2018 and December 2019, 764 charts were retrospectively reviewed for patients who received antimicrobial treatment and in whom an ASP intervention was performed. Patients were allocated into 2 groups: those whose ASP interventions were accepted and those whose were rejected. Provider responses were then documented within 24 hours of being communicated. The primary outcome was hospital LOS. Secondary outcomes included 30-day readmission rates and inpatient antimicrobial duration of therapy (DOT). Results: There were 384 patients with an accepted ASP intervention and 380 with a denied intervention. Baseline characteristics were similar between both groups, except for a difference in the types of intervention performed (P < 0.001). The median hospital LOS for patients in the accepted intervention group was 6.5 days compared to 7 days in the rejected intervention group (P = 0.009). Antimicrobial DOT was also shorter in the accepted intervention group (5 vs 7 days; P < 0.001). There was no difference in 30-day readmission rates (P = 0.98). Conclusion: Prescriber acceptance to ASP interventions decreases hospital LOS and antimicrobial DOT without affecting 30-day readmission rates.

Operative Management of Acute Appendicitis Was Safe During the COVID-19 Pandemic Shutdown

IntroductionIn the spring of 2020, New York City was one of the first epicenters of the COVID outbreak. In this study, we evaluate the incidence and treatment of appendicitis in two New York City community hospitals during the COVID pandemic. MethodsThis retrospective study focused on the incidence and outcome of acute appendicitis in the adult population (>18 y old) during peak-COVID periods (March 16, 2020,-June 15, 2020) compared to pre-COVID and post-COVID periods. We compared the number of patients who underwent operative versus nonoperative management, patient demographics, length of stay (LOS), complications, and readmission rates within these time periods. Data are presented as mean ± standard deviation (analysis of variance). ResultsFrom January 1, 2020 to December 31, 2020, 393 patients presented with acute appendicitis and 321 (81.7%) were treated operatively, compared to 441 total and 366 treated operatively (83%) in 2019 (P = 0.88). During the COVID outbreak, fewer patients presented with appendicitis (mean 6.9 ± 1 pre-COVID case/week, 4.4 ± 2.4 peak-COVID cases/week and 7.6 ± 0.65 post-COVID cases/week, P = 0.018) with no significant difference in the pre-COVID and post-COVID period. There was no difference in LOS between the pre-, peak-, and post-COVID periods with a median of 1 for all the three, (interquartile range (IQR): 0.8-2, 0.6-2, 0.6-2, respectively, P = 0.43). Additionally, there was no difference in 30-day readmission rates (4.2%, 0%, 3.9%, P = 0.99) and postoperative complications (4.2%, 0%, 2.9%, P = 0.98). ConclusionsDuring peak-COVID, there was a significant reduction in the number of patients who presented with acute appendicitis without a post rebound increase in presentation. Those who presented during peak-COVID were able to undergo operative management safely, without affecting LOS or postoperative complications.

Dedicated Next Day Discharge Post Minimalist TAVI: The Tasmanian Experience.

To assess the safety, feasibility and independent predictors of next day discharge (NDD) in patients undergoing minimalist transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS) in a real-world Australian population. This single centre study reviewed 135 consecutive patients who underwent minimalist transfemoral TAVI from June 2020 to February 2022. Baseline demographics, procedural characteristic and outcomes were obtained. All patients were assessed by the local protocol for NDD. Patients were then divided into two groups: those who achieved next day discharge (NDD) and those requiring >1 overnight hospital stay. Univariate, bivariate and stepwise multivariate logistic regression modelling was used to identify the predictors of successful next day discharge. The mean age of the cohort was 82.9±5.7 years with 62.3% patients male, the average STS score was 4.1±2.4. All 135 patients underwent a successful transfemoral TAVI procedure, with 131 (97%) receiving a balloon-expandable valve. Ninety-seven (97) (71.9%) patients achieved NDD. Thirty (30)-day outcomes were excellent with a 30-day mortality of 0.7%, transient ischaemic attack/cardiovascular accident (TIA/CVA) 1.5%, major vascular complication 1.5% and 11.4% need for permanent pacemaker (PPM). In patients not achieving NDD, the average length of stay (LOS) was 3.0 days. Baseline characteristics demonstrated pre-existing first degree atrioventricular (AV) block and right bundle branch block (RBBB) as statistically significant negative predictors of NDD on univariate analysis. Next day discharge was achievable in only 50% of patients who suffered any minor or major procedural complication (15/30). Stepwise multivariate logistic regression modelling demonstrated female gender (OR 3.094, 95% CI 1.141-8.391, p=0.026), smaller aortic valve area (AVA) (OR 48.265, 95% CI 2.269-102.6, p=0.013), the presence of diabetes mellitus (OR 0.594, 95% CI 0.356-0.991, p=0.046) and a longer procedure time (OR 0.960, 95% CI 0.935-0.986, p=0.002) as statistically significant negative predictors of NDD. In addition, there was no difference in 30-day readmission rates between the NDD and non-NDD cohort (7.2% vs 10.5%, p=0.386). Next day discharge is safe and feasible in almost three quarters of patients undergoing minimalist TAVI for severe AS in a predominantly balloon expandable valve cohort, with a very low rate of 30-day readmission. NDD provides advantages for hospital efficiency and improved cost-effectiveness. Female gender, smaller AVA, the presence of diabetes mellitus and a longer procedure time were independent negative predictors of successful NDD.

Comparison of antipsychotic prescribing practices following failure of antipsychotic monotherapy in the acute care setting.

Numerous strategies exist following antipsychotic monotherapy failure including transition to another antipsychotic, dosing above FDA recommendations, or dual antipsychotic therapy. This study described antipsychotic prescribing practices on an acute psychiatry unit following antipsychotic monotherapy failure and compared outcomes to determine if any strategy resulted in superior short-term outcomes. This retrospective chart review assessed postintervention time to discharge for patients with schizophrenia or schizoaffective disorder requiring therapy change following treatment failure. Secondary outcomes included 30-day readmission rate, length of stay, and discharge chlorpromazine equivalents. There were no differences in number of past antipsychotic trials between groups (4.8 vs 4.5; P = .73). Of all the patients, 73% (n = 30) discharged on alternative antipsychotic monotherapy while 27% (n = 11) discharged on dual antipsychotic therapy. No patients had doses increased above FDA recommendations. The alternative antipsychotic group had shorter mean postintervention time to discharge (8.8 vs 20.6 days; P = .003) and shorter mean length of stay (16.7 vs 32.1 days; P = .03). Median time to discharge was not statistically significant (6.4 vs 14.0 days; P = .17). The dual antipsychotic group had higher mean chlorpromazine equivalents (723 mg vs 356 mg; P = .002). There was no difference in 30-day readmission rates (16.7% vs 27.3%; χ2 = 0.5765; P = .45). This study found that following failure of antipsychotic monotherapy, transition to an alternative antipsychotic was associated with decreased mean time to discharge as compared to dual antipsychotic therapy. Further studies are needed to assess long-term clinical implications of these findings.

Follow-up Blood Cultures in Gram-negative Bacteremia: How Do They Impact Outcomes?

Several studies have questioned the utility of obtaining follow-up blood cultures in Gram-negative bacteremia, but the impact of this practice on clinical outcomes is not fully understood. A retrospective cohort study of adult patients admitted with Gram-negative bacteremia over a two year period, to compare outcomes in those with and without follow-up blood cultures obtained. Data collected included demographics, comorbidities and presumed source of bacteremia. White blood cell count and presence of fever or hemodynamic compromise on the day of follow-up blood culture were recorded. The primary objective was to compare 30-day mortality between the two groups. Secondary objectives included comparing 30-day readmission rate, hospital length of stay and antibiotics duration. Of 482 included patients, 321 (66.6%) had follow-up blood cultures. 96% of follow-up blood cultures were negative. Persistent bacteremia occurred in 9 patients. There was no significant difference in 30-day mortality between those with and without follow-up blood cultures (2.9% and 2.7% respectively, P > 0.999), and no difference in 30-day readmission rate (21.4% and 23.4% respectively, P = 0.704). Patients with follow-up blood cultures had longer hospital length of stay (7 days vs 5 days, P < 0.001), and longer mean antibiotic duration (14 days vs 11 days, P < 0.001). Obtaining follow-up blood cultures in Gram-negative bacteremia had no impact on 30-day mortality or 30-day readmission rates. It was associated with longer length of stay and antibiotic duration. We found this practice to be low yield and its routine use may be of questionable value.

Abstract 9981: Comparison of 30-day Readmission and Healthcare Costs Between Early and Late Catheter Directed Thrombolysis for Acute Pulmonary Embolism in the United States

Introduction: Pulmonary embolism (PE) is a major cause of morbidity and mortality accounting for 100,000 deaths per year in the United States and 5-10% of in-hospital deaths. There is sparse comparative data on readmission patterns and healthcare costs in patients who undergo early versus late catheter directed thrombolysis (CDT) for acute PE. Hypothesis: Procedure Day for acute PE may be associated with difference in 30-day readmission rates and healthcare costs. Methods: This study was performed by using National readmission database between January 2016 and November 2019. Patients with acute PE who underwent CDT were identified using the International Classification of Diseases, Tenth Edition (ICD 10) codes. Patients who were &lt;18 years old and patients who underwent thrombolysis for STEMI and Ischemic stroke were excluded. Results: Among a total of 23,564 patients who underwent CDT for acute pulmonary embolism, 12,528 (53.2%) were male and 11034 (46.8%) were female (P=0.014). The mean age of the patients was 60.3 years. The median length of hospital stay was 4 days. Thirty-day readmission rates were higher for patients who underwent CDT on Day 2 or afterwards compared to Day 1 and Day 0 (7.1% vs 5.7% vs 5.2%, for day 2, day 1 and day 0 respectively; p=0.016). Patients who had CDT on Day 2 or more had a higher rate of 30-day readmission mortality compared to those who had CDT on Day 1 or 0 (0.6% vs 0.3% vs 0.2%, for day 2, day 1 and day 0 respectively; Adjusted OR 2.96, 95% CI 1.18 to 7.47 (Ref: day 0), p = 0.021). Thirty-day readmission for heart failure was higher among patients who had CDT on Day 2 vs those who had CDT on Day 0 of admission (2% vs 1.0% vs 0.9%, for day 2, day 1 and day 0 respectively; Adjusted OR 1.97, 95% CI 1.24 to 3.13 (Ref: day 0), p=0.004). Total 30-day costs for patients who underwent CDT on day 2 or more was higher in patients with CDT on day 2 ($55,087; IQR $41,361-$74,092) compared to those with CDT on Day 1 ($45,942; IQR $36,016-$61,211) or Day 0 ($44,814; IQR $34,264-$60,072) (P &lt;0.001). Conclusions: Delayed CDT for acute PE was associated with increased rates of 30-day readmission, readmission mortality, readmission for heart failure and increased healthcare costs. These findings emphasize the need for earlier CDT for the treatment of acute PE.

S70 Impact of Frailty on Readmissions and Inpatient Outcomes of Older Adults (≥65 Years) With Acute Pancreatitis

Introduction: Acute pancreatitis (AP) is a major cause of adult hospitalizations in the United States. More than 10 billion US dollars are spent each year on treatment of patients admitted for AP. While data on hospitalizations for AP is widely analyzed, there are limited studies regarding the role that frailty has on this group of patients. The goal of our study is to determine what impact patient frailty has on readmission and on inpatient outcomes. Methods: The National Readmission Database (NRD) 2017-18 was queried. AP patients age >= 65 were selected based on appropriate ICD-10 diagnostic codes. Hospital frailty risk score (HFRS) was calculated for all the AP patients such that patients with HFRS score < 5 were considered to be not frail (NF) and patients with HFRS score >= 5 were considered frail based on the prevalence of comorbidities in each individual. Differences in mean length of stay (LOS) and in-hospital mortality were analyzed using multivariate logistic regression. Cox proportional-hazards regression analysis was used to determine the difference in 30-day readmission between the two groups. Results: A total of 91,031 patients aged 65 years and older with AP were identified in our search. Of these, 31,012 (mean age 76.5) were considered frail (average HFRS score 8.2) and the remaining 60,020 (mean age 74.1) were deemed to be not frail (average HFRS score 2.1). The rate of in-patient mortality was significantly higher in the frail group compared to the not frail group (3.53% vs 0.27%) with an adjusted odds ratio of 10.95 (p < 0.001). Frail AP patients had a significantly longer LOS when compared to NF (6.8 vs 3.6 days; adjusted mean difference 2.6 days, p < 0.001). The difference in 30-day readmission rates between the frail and NF group was also highly statistically significant; (12.0% vs 8.9%, respectively; adjusted hazard ratio 1.2%, 95% CI 1.15-1.26%; p < 0.001). Conclusion: AP patients consume a great deal of healthcare resources and the burden is increasing due to the aging population. Our study finds that the elderly frail group of AP patients is more fragile and has a higher 30-day readmission rate. It would be prudent to risk stratify patients admitted with AP and devise a more customized treatment approach for the more vulnerable frail group, in hopes of reducing inpatient mortality and lessening the burden on our healthcare system that results from longer stays and readmissions.
