Higher 30-day Readmission Rates Research Articles

Impact of alcohol use disorder on inpatient hospitalizations: A comparison of outcomes between urban and rural Veterans Affairs hospitals.

Alcohol use disorder (AUD) is a leading cause of morbidity and mortality that disproportionately affects rural residents and Veterans. To evaluate the burden of AUD in admissions at rural and urban hospitals within the Veterans Health Administration (VHA) comparing patient characteristics, clinical outcomes, and 1-, 3-, and 5-year mortality rates. Retrospective cross-sectional study of patients admitted to VHA hospitals from 2016 to 2020, with a primary or secondary diagnosis related to AUD. Follow-up mortality data was collected through September 30, 2023. From 2.9 million qualifying admissions, AUD-related diagnoses were present in 14.3% of admitted patients (427,375 admissions among 190,152 unique patients in 129 facilities). Rural hospitals (n = 22) had a significantly higher overall admission rate for AUD-related diagnoses (21.6% vs. 14.8%, p = .011), higher 30-day readmission rates (17.8% vs. 15.3%, p < .001), but lower hospital-level average length of stay (median = 4.3 vs. 5.6, p < .001). Mortality in rural hospitals was lower than urban at 1 year (9.6% vs. 11.4%, p < .001), 3 years (20.7% vs. 23.1%, p < .001), and 5 years (30.4% vs. 32.9%, p < .001). Rural VHA hospitals have a higher proportion of patients admitted with AUD-related diagnoses and higher readmission rates, but lower mortality rates. Approximately, one in three patients admitted with an AUD-related diagnosis died within the 5-year follow-up period. The mortality rates observed are extraordinary and deserve urgent attention. A comprehensive plan to address AUD in the Veteran population, including how we approach and engage patients in treatment during hospitalizations with any primary or secondary AUD diagnoses, is needed.

Prevalence, trends, and outcomes of hematological malignancies in patients with hemophagocytic lymphohistiocytosis

ABSTRACT Backgrounds Hemophagocytic lymphohistiocytosis (HLH) is an acute, rapidly progressive systemic inflammatory disorder that often occurs secondary to hematological malignancies among other conditions in adults. Although the annual incidence of HLH is increasing, detailed epidemiological knowledge of HLH is still limited, especially in patients with hematological malignancies. Objectives To analyze the impact of hematological malignancies on the epidemiology and outcomes of HLH. Study design Data from the National Readmission Database (NRD) from 2011 to 2020 were analyzed to explore the epidemiological trends and in-hospital outcomes of HLH patients, particularly those with hematological malignancies. Results Our analysis included 7579 HLH hospitalizations, with hematological malignancies implicated in 24.01% of cases. Our findings reveal a steady increase in HLH diagnoses from 145 cases in 2011 to 1848 in 2020, with the proportion linked to hematological malignancies remaining consistent. Patients with hematological malignancies-associated HLH exhibited higher rates of in-hospital mortality (31.6%) than those without (14.4%), and a higher 30-day readmission rate, underscoring a critical need for early detection and treatment revision. Conclusions Despite the increasing awareness and diagnosis of HLH, the prognosis of patients with HLH associated with hematological malignancies remains poor, highlighting the urgent need for improved management strategies and therapeutic interventions.

Characteristics and Readmission Risks Following Sepsis Discharges to Home

Objective: To examine the characteristics and risk factors associated with 30-day readmissions, including the impact of home health care (HHC), among older sepsis survivors transitioning from hospital to home. Research Design: Retrospective cohort study of the Medical Information Mart for Intensive Care (MIMIC)-IV data (2008–2019), using generalized estimating equations (GEE) models adjusting for patient sociodemographic and clinical characteristics. Subjects: Sepsis admission episodes with in-hospital stays, aged over 65, and discharged home with or without HHC were included. Measures: The outcome was all-cause hospital readmission within 30 days following sepsis hospitalization. Covariates, including the primary predictor (HHC vs. Home discharges), were collected during hospital stays. Results: Among 9115 sepsis admissions involving 6822 patients discharged home (66.8% HHC, 33.2% Home), HHC patients, compared with those discharged without services, were older, had more comorbidities, longer hospital stays, more prior hospitalizations, more intensive care unit admissions, and higher rates of septic shock diagnoses. Despite higher illness severity in the HHC discharges, both groups had high 30-day readmission rates (30.2% HHC, 25.2% Home). GEE analyses revealed 14% higher odds of 30-day readmission for HHC discharges after adjusting for risk factors (aOR: 1.14; 95% CI: 1.02–1.27; P=0.02). Conclusions: HHC discharges experienced higher 30-day readmission rates than those without, indicating the need for specialized care in HHC settings for sepsis survivors due to their complex health care needs. Attention to sepsis survivors, regardless of HHC receipt, is crucial given the high readmission rates in both groups. Further research is needed to optimize postacute care/interventions for older sepsis survivors.

Is conversion to duodenal switch after Roux-en-Y gastric bypass safe? Short-term outcomes review.

Weight regain after Roux-en-Y gastric bypass (RYGB) can be seen in approximately 20% of patients. Surgical management options include revision of RYGB and conversion to duodenal switch (DS). Using recently included revisional surgery variables in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, we compared the safety and efficacy of RYGB revision versus conversion to DS. An analysis of the 2020 MBSAQIP Participant Use Data File (PUF) revealed 1421 patients who underwent revision of RYGB (n = 1255) or conversion from RYGB to DS (n = 166) for inadequate weight loss or weight regain. Patient characteristics, preoperative body mass index (BMI), operating room (OR) time, and 30-day complications were compared between groups. When compared with the revision RYGB group, the DS group had higher mean BMI (47.5 vs 42.7, p < 0.001) and longer operative time (209.1 vs 133.4min, p < 0.001). DS had higher rates of any complication compared to revision RYGB (22.3 vs 5.58%, p < 0.001). DS had higher 30-day readmission rates (16.3 vs 5.50%, p < 0.001), reoperation within 30days (9.04 vs 2.87%, p < 0.001), venous thromboembolism (VTE) (3.01 vs 0.08%, p < 0.001), intensive care unit (ICU) admission (8.43 vs 0.72%, p < 0.001), anastomotic leak (7.83 vs 0.40%, p < 0.001), surgical site occurrence (SSO) (11.5 vs 2.71%, p < 0.001), and death (0.60 vs 0%, p < 0.001). This short-term data suggests that conversion of RYGB to DS is associated with higher rates of postoperative complications when compared with revision of RYGB. Given the complexity of the procedure, it is best performed by experienced surgeons with careful consideration given to appropriate patient selection and only after extensive patient counseling on associated risks and complications.

Robotic kidney transplant has superior outcomes compared to open kidney transplant: results of a propensity match analysis.

Several studies have demonstrated the feasibility of robotic kidney transplant (RKT) as a safe alternative to open kidney transplant (OKT). However, significant selection bias in RKT patient selection limits meaningful comparison between the two techniques. This is a single-center retrospective review of a prospectively maintained kidney transplant database (2021-2024). Outcomes after the first 50 "non-selected" RKTs are compared with a contemporary cohort of 100 OKTs after propensity score matching for age, gender, BMI and type of donation (living vs deceased). Data pertinent to recipient demographics, intraoperative parameters, and short-term post-operative outcomes were collected and compared. Both groups were well-matched for recipient age, gender, BMI, and donation type. RKT group had significantly longer total operative time (RKT 258min vs. OKT 183min; p < 0.0001) and warm ischemia time (RKT 37min vs. OKT 31min; p < 0.0001) but significantly less blood loss (OKT 155ml vs. RKT 93ml). Average length of hospital stay for both groups was 5days, with OKT group demonstrating significantly higher rates of post-operative complications (OKT 31% vs. RKT 14%; p = 0.028), return to OR (OKT 15% vs. RKT 2%; p = 0.021), hematoma (OKT 13% vs. RKT 2%; p = 0.0355), and lymphocele (OKT 25% vs. RKT 6%; p = 0.0039). OKT group also had higher 30-day readmission rate (OKT 31% vs. RKT 14%) and post-operative opioid requirement (OKT 93 MME vs. RKT 65; p = 0.0254). There were no differences in rates of wound infection, urine leaks, delayed graft function, acute rejection, graft loss, and patient death between the two groups. RKT is a safe and viable alternative to OKT as a first-choice procedure for all patients with ESRD. RKT offers many advantages over OKT which can lead to its wider adoption in the coming years as the new standard of care for ESRD patients.

Comparing oncologic and surgical outcomes of robotic and laparoscopic distal pancreatectomy: a propensity-matched analysis

BackgroundThe frequency of minimally invasive distal pancreatectomy is gradually exceeding that of the open approach. Our study aims to compare short-term outcomes of robotic (RDP) and laparoscopic (LDP) distal pancreatectomies for pancreatic ductal adenocarcinoma (PDAC) using a national database.MethodsThe National Cancer Database was utilized to identify patients with PDAC who underwent distal pancreatectomy from 2010–2020. Short-term technical and oncologic outcomes such as margin status and nodal harvest were included. Propensity-score matching (PSM) was performed comparing LDP and RDP cohorts. Multivariate logistic-regression models were then used to assess the impact of institutional volume on the MIDP surgical and technical oncologic outcomes.Results1537 patients underwent MIDP with curative intent. Most cases were laparoscopic (74.4%, n = 1144), with a gradual increase in robotic utilization, from 8.7% in 2010 to 32.0% of MIDP cases ten years later. For PSM, 698 LDP patients were matched with 349 RDP. The odds of conversion to an open case were 58% less in RDP (12.6%) compared to LDP (25.5%) with no statistically significant difference in technical oncologic results. There was no difference in length of stay (OR = 1.0[0.7–1.4]), 30-day mortality (OR = 0.5[0.2–2.0]) or 90-day mortality (OR = 1.1[0.5–2.4]) between RDP and LDP, although there was a higher 30-day readmission rate with RDP (OR = 1.71[1.1–2.7]). There were statistically significant differences in technical oncologic outcomes (nodal harvest, margin status, initiation of adjuvant therapy) based on MIDP volume quartiles.ConclusionLaparoscopic and robotic distal pancreatectomy have similar peri- and post-operative surgical and oncologic outcomes, with a higher rate of conversion to open in the laparoscopic cohort.

The Burden of Health Care Utilization, Cost, and Mortality Associated with Select Surgical Site Infections

ObjectiveThis study assessed the additional healthcare utilization, cost, and mortality resulting from three surgical site infections (SSIs): mediastinitis/SSI after coronary artery bypass graft, SSI after bariatric surgery for obesity, and SSI after certain orthopedic procedures. MethodsThis retrospective observational cohort study used commercial and Medicare Advantage claims from 2016 to 2021. Patients with one of three SSIs were compared to a 1:1 propensity score-matched group of patients with the same surgeries but without SSI on outcomes up to one year post-discharge. ResultsThe total sample size was 4,620. Compared to their matched cohorts, the three SSI cohorts had longer mean index inpatient length of stay (LOS; adjusted days difference ranged from 1.73 to 6.27 days; all p < 0.001) and higher 30-day readmission rates (adjusted odds ratio ranged from 2.8 to 25.1; all p ≤ 0.001). The SSI cohort for orthopedic procedures had higher 12-month mortality (hazard ratio of 1.6; p = 0.01), though other cohorts did not have significant differences. Total medical costs were higher in all three SSI versus matched comparison cohorts for the index episode and six months and one year post-discharge. Average adjusted one-year total medical cost differences ranged from $40,606 to $68,101 per person, depending on the cohort (p < 0.001), with out-of-pocket cost differences ranging from $330 to $860 (p < 0.05). ConclusionPatients with SSIs experienced higher LOS, readmission rates, total medical costs, and higher mortality for some populations compared to their matched comparison cohorts during the first year post-discharge. Identifying strategies to reduce SSIs is important both for patient outcomes and affordability of care.

Prior abdominal surgery is not associated with 30-day mortality or morbidities after endovascular repair of complex abdominal aortic aneurysm.

Prior abdominal surgery (PAS) has the potential to affect outcomes of abdominal aortic aneurysm (AAA) repair. Recently, endovascular aneurysm repair (EVAR) has been expanded among patients with complex AAA, which involves visceral branches in the upper abdominal aortic. However, outcomes of EVAR for complex AAA in patients with PAS have not been examined. This study aimed to investigate the impact of PAS on 30-day outcomes in EVAR for complex AAA. Patients who underwent EVAR for complex AAA were identified in ACS-NSQIP targeted database from 2012 to 2022. Complex AAA was defined as juxtarenal, suprarenal, or pararenal proximal extent, Type IV thoracoabdominal aneurysm, or aneurysms treated with Zenith Fenestrated endograft. Patients with age less than 18 years, ruptured AAA with or without hypotension, acute intraoperative conversion to open, and emergency presentation were excluded. Multivariable logistic regression was used to compare 30-day postoperative outcomes of patients with and without PAS. Demographics, baseline characteristics, aneurysm diameter, indication for surgery, proximal and distant aneurysm extent, anesthesia, and concomitant procedures were adjusted. There were 515 (28.34%) and 1302 (71.66%) patients with and without PAS, respectively, who underwent EVAR for complex AAA. Patients with and without PAS had comparable 30-day mortality (3.11% vs 3.00%, aOR = 0.766, 95 CI = 0.407-1.442, p = .41). Organ system complications including cardiac complications, stroke, pulmonary complications, and renal complications were comparable between patients with and without PAS. All other 30-day outcomes were similar between groups. However, patients with PAS had higher 30-day readmission rate (11.65% vs 7.14%, aOR = 1.634, 95 CI = 1.145-2.331, p = .01). While PAS has high prevalence among patients undergoing EVAR for complex AAA, it does not impact 30-day mortality and morbidities. Thus, EVAR for complex AAA can be considered safe for patients with PAS in terms of short-term outcomes, despite the long-term prognosis in these patients being needed in further studies.

Upfront laparotomy versus conversion from minimally invasive surgery to open surgery in colon cancer: Is there a difference in outcomes?

BackgroundIt is unclear whether conversion from minimally invasive surgery to laparotomy in patients with colon cancer contributes to worse outcomes compared with those operated by laparotomy. In this study, we aimed to assess the implications of transitioning from minimally invasive surgery to laparotomy in patients with colon cancer compared with patients undergoing upfront laparotomy. MethodsA retrospective analysis of the National Cancer Database, including patients with stages I to III colon cancer (2010–2019). Patients who underwent either upfront laparotomy (Open Surgery Group) or minimally invasive surgery converted to open surgery (Converted Surgery Group) were included. Groups were balanced using propensity-score matching. Primary outcome was overall survival, and secondary outcomes included 30- and 90-day mortality and 30-day readmission rates. ResultsThe study included 65,083 operated patients with stage I to III colon cancer; 57,091 patients (87.7%) were included in the Open Surgery group and 7,992 (12.3%) in the Converted Surgery group. 93.5% were converted from laparoscopy, and 6.5% were converted from robotic surgery. After propensity-score matching, 7,058 patients were included in each group. Median overall survival was significantly higher in the Converted Surgery group (107.3 months) than in the Open Surgery group (101.5 months; P = .006). A survival benefit was seen in patients >65 years of age (79.5 vs 71.9 months; P = .001), left-sided disease (129.4 vs 114.5 months; P < .001), and with a high Charlson comorbidity index score (=3; 58.9 vs 42.3 months; P = .03). Positive margin rates were similar between the groups (6.3% vs 5.6%; P = .07). Converted patients had a higher 30-day readmission rate (6.7% vs 5.6%, P = .006) and shorter duration of stay (median, 5 vs 6 days, P < .001) than patients in the Open Surgery group. In addition, 30-day mortality was comparable between the groups (2.9% vs 3.5%; P = .07). ConclusionConversion to open surgery from minimally invasive surgery was associated with better overall survival compared with upfront open surgery. A survival benefit was mainly seen in patients >65 years of age, with significant comorbidities, and with left-sided tumors. We believe these data suggest that, in the absence of an absolute contraindication to minimally invasive surgery, it should be the preferred approach in patients with colon cancer.

Spontaneous coronary artery dissection outcomes among pregnant vs. non-pregnant women.

Spontaneous coronary artery dissection (SCAD) has become increasingly recognized. It accounts for <1-4% of acute coronary syndrome presentations. Overall, however, it makes up over 40% of pregnancy-associated myocardial infarction. Furthermore, pregnancy-associated spontaneous coronary artery dissection (P-SCAD) is described to have a greater degree of clinical manifestations, including left ventricular dysfunction, shock, and left main or multivessel involvement. The findings are disconcerting, though many studies evaluating P-SCAD are based on case series data or are single centre studies. The aim of this study was to evaluate a larger national dataset to evaluate the outcomes of SCAD and specifically P-SCAD in an attempt to better characterize the severity and clinical nature of this condition. To conduct this study, we analysed the National Readmission Database from January 2016 to December 2020. Propensity matching was done using the Greedy 1:1 method. Multivariate logistics and time-to-event Cox regression analysis models were built by including all confounders significantly associated with the outcome on univariable analysis with a cut-off P-value of 0.2. In multivariate regression analysis, P-SCAD patients had a non-propensity matched odds ratio (OR) of 0.21 (0.3-1.54, P = 0.123) of dying and a propensity matched OR of 0.11 (0.02-0.61, P = 0.012) of dying. Thirty-day readmission rate for P-SCAD was 15.8% (n = 93) and for non-pregnant spontaneous coronary artery dissection (NP-SCAD) was 11.2% (n = 2286); non-propensity matched OR for readmission for PSCAD patients was 1.68 (1.24-2.29, P = 0.001) and propensity matched OR was 3.39 (1.93-5.97, P < 0.001). Among hospitalized patient, P-SCAD was associated with similar clinical outcomes and reduced incidence of death when compared with NP-SCAD, though had higher rates of 30-day readmission. Larger-scale observational data will be needed to ascertain the true incidence of cardiovascular complications as it relates to P-SCAD.

Association between admission albumin levels and 30-day readmission after hip fracture surgery in geriatric patients: a propensity score-matched study

PurposeThis study aimed to evaluate the correlation admission albumin levels and 30-day readmission after hip fracture surgery in geriatric patients.MethodsIn this retrospective cohort study, 1270 geriatric patients admitted for hip fractures to a level I trauma center were included. Patients were stratified by clinical thresholds and albumin level quartiles. The association between admission albumin levels and 30-day readmission risk was assessed using multivariate logistic regression and propensity score-matched analyses. The predictive accuracy of albumin levels for readmission was evaluated by ROC curves. The dose–response relationship between albumin levels and readmission risk was examined. ResultsThe incidence of 30-day readmission was significantly higher among hypoalbuminemia patients than those with normal albumin levels (OR = 2.090, 95%CI:1.296–3.370, p = 0.003). Furthermore, propensity score-matched analyses demonstrated that patients in the Q2(35.0–37.9 g/L) (OR 0.621, 95%CI 0.370–1.041, p = 0.070), Q3(38.0–40.9 g/L) (OR 0.378, 95%CI 0.199–0.717, p < 0.001) and Q4 (≥ 41 g/L) (OR 0.465, 95%CI 0.211–0.859, p = 0.047) quartiles had a significantly lower risk of 30-day readmission compared to those in the Q1(< 35 g/L) quartile. These associations remained significant after propensity score matching (PSM) and subgroup analyses. Dose–response relationships between albumin levels and 30-day readmission were observed.ConclusionsLower admission albumin levels were independently associated with higher 30-day readmission rates in elderly hip fracture patients. Our findings indicate that serum albumin may assist perioperative risk assessment, and prompt correction of hypoalbuminemia and malnutrition could reduce short-term readmissions after hip fracture surgery in this high-risk population.

Transcatheter aortic valve implantation with and without mitral stenosis — A National Readmission Database study

IntroductionMitral valve stenosis (MS) can be concomitantly present in patients undergoing Transcatheter Aortic Valve Implantation (TAVI). Some studies have reported up to one-fifth of patients who underwent TAVI also have MS. The relationship between mitral stenosis and TAVI has led to concerns regarding increased adverse cardiac outcomes during and after the procedure. MethodsThe Nationwide Readmission Database (NRD 2016–2019) was utilized to identify TAVI patients with MS with ICD-10-CM codes. The primary outcome was a 30-day readmission rate. Secondary outcomes included predictors of all-cause readmissions, length of stay, and total hospitalization cost. We assessed readmission frequency with a national sample weighed at 30 days following the index TAVI procedure. Unadjusted and adjusted odds ratios were analyzed for in-hospital outcomes using univariate and multivariate logistic regression for study cohorts. ResultsA total of 217,147 patients underwent TAVI procedures during the queried time period of the study. Of these patients, 2140 (0.98 %) had MS. The overall 30-day all-cause readmission rate for the study cohort was 12.4 %. TAVI patients with MS had higher rates of 30-day readmissions (15.8 % vs 12.3 %, aOR 1.22, CI: 1.03–1.45, P < 0.01). Additionally, TAVI patients with MS had longer lengths of hospital stay during index admissions (5.7 vs. 4.3 days), along with higher total hospitalization costs ($55,157 vs. $50,239). In contrast, in-hospital mortality during index TAVI admission did not differ significantly between the two groups, although there was a trend toward higher mortality in the MS group (2.1 % vs. 1.5 %). Among the TAVI MS cohort, patients admitted on weekends (aOR: 1.11, 95 % CI: 1.02–1.22, P = 0.01), admitted to non-metropolitan hospitals (aOR: 1.29, 95 % CI: 1.11–1.66, P = 0.04) and presence of co-morbidities such as atrial fibrillation (AF)/flutter (aOR: 1.24, 95 % CI: 1.16–1.32, P < 0.01), chronic obstructive pulmonary disease (COPD) (aOR: 1.16, 95 % CI: 1.11–1.22, P < 0.01), prior stroke (aOR: 1.09, 95 % CI: 1.03–1.14, P < 0.01), chronic kidney disease (CKD) ≥3 (aOR: 1.16, 95 % CI: 1.11–1.22, P < 0.01), end-stage renal disease (ESRD) (aOR: 1.75, 95 % CI: 1.61–1.90, P < 0.01), and anemia (aOR: 1.23, 95 % CI: 1.18–1.28, P < 0.01) were associated with increased odds of readmission. ConclusionConcomitant MS in patients undergoing TAVI is associated with higher readmission rates and total hospital costs. This can contribute significantly to healthcare-related burdens. Further studies are required to evaluate in-hospital outcomes and predictors of readmission in patients undergoing TAVI with the presence of concomitant MS.

The correlation between admission hyperglycemia and 30-day readmission after hip fracture surgery in geriatric patients: a propensity score-matched study.

This study aimed to investigate the association between admission hyperglycemia and 30-day readmission after hip fracture surgery in geriatric patients. This retrospective study included 1253 geriatric hip fracture patients. Patients were categorized into normoglycemia(<6.10 mmol/L) and hyperglycemia groups(≥6.10 mmol/L) based on admission blood glucose. We performed multivariable logistic regression analyses and propensity score matching (PSM) to estimate adjusted odds ratios and 95% confidence intervals for 30-day readmission, controlling for potential confounding factors. An analysis of the dose-dependent association between admission blood glucose and the probability of 30-day readmission was performed. Additional subgroup analysis was conducted to examine the impact of other factors on the relationship between admission blood glucose and 30-day readmission. Patients with hyperglycemia had higher 30-day readmission rates than normoglycemic patients before (19.1% vs 9.7%, p<0.001) and after PSM (18.1% vs 12.3%, p=0.035). Admission hyperglycemia was an independent predictor of increased 30-day readmission risk, with an adjusted odds ratio of 1.57 (95% CI 1.08-2.29, p=0.019) after multivariable regression and 1.57 (95% CI 1.03-2.39, p=0.036) after PSM. A dose-response relationship was observed between higher glucose levels and increased readmission risk. Admission hyperglycemia is an independent risk factor for 30-day readmission after hip fracture surgery in the elderly. Routine glucose testing upon admission and perioperative glycemic control may help reduce short-term readmissions in this vulnerable population.

EFFECTS OF NUTRITION STATUS AND PERIOPERATIVE NUTRITION SUPPLEMENT COMPLETION ON POSTOPERATIVE OUTCOMES IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE UNDERGOING SURGERY

Abstract BACKGROUND Malnutrition is common in inflammatory bowel disease, (IBD) and is associated with poor disease activity, greater hospital length of stay (LOS), higher 30-day readmission rates, and increased risk of postoperative complications. Structured, multimodal prehabilitation including nutrition counseling improves various outcomes after elective cancer and orthopedic surgeries. We examined the effects of malnutrition and perioperative nutrition supplementation on surgical outcomes in IBD patients participating in a multimodal prehabilitation program. METHODS This was a retrospective study of patients aged 18-80 enrolled in a 10-week prehabilitation program undergoing surgery for IBD. Beginning 4 weeks prior to surgery, patients met with a multidisciplinary team including a nurse practitioner, physical therapist and registered dietitian. Patients were provided 3 preoperative carbohydrate loading oral nutrition supplements (ONS) 48 hours prior to surgery, and 20 perioperative immunonutrition ONS. Malnutrition was defined using the Global Leadership in Malnutrition criteria as moderate or severe. We used Fisher’s exact test to determine associations between malnutrition, ONS use, and postoperative complications (defined by the comprehensive complication index (CCI, with CCI scores &amp;gt;20 classified as severe)), and 30-day readmission. Logistic and linear regression were used to analyze length of stay (LOS), opioid use (defined as morphine milligram equivalents, MME), nutrition status, and ONS completion. RESULTS 25 patients (48% female, mean age 44, 18 (72%) with Crohn’s disease) completed the prehabilitation program between 05/2022 and 10/2023. 10 patients (40%) met criteria for malnutrition (of these, 50% were moderate and 50% severe). Malnutrition was not significantly associated with CCI severity (p=0.07), LOS (p =0.07), opioid use (p=0.07) or 30 day readmission rates (0.06). Higher ONS use for carbohydrate loading and immunonutrition were more likely to have a LOS&amp;lt;5 days (p=0.05 and p=0.03 respectively). CONCLUSION ONS for preoperative carbohydrate loading and perioperative immunonutrition may shorten LOS after surgery among patients with IBD. In our study, higher amounts of ONS consumption led to a shorter LOS. Larger, controlled studies will help to further clarify the effects of malnutrition, carbohydrate loading, and immunonutrition among patients with IBD preparing for surgery.

Total Hip Arthroplasty in Hemophilic Patients: are their Results Similar to those of Nonhemophilic Patients?

Total hip arthroplasty (THA) is the mainstay therapy for patients with terminal hemophilic arthropathy of the hip. However, the largest case series published between 2017 and 2023 in the literature on THA in patients with hemophilia have found a higher 1-year infection rate (8.1% versus 3.4%) in hemophilia patients than in the general population, a higher rate of in-hospital bleeding complications (38.7% versus 16.1%), a higher length of stay (6 days versus 3 days) and a higher 30-day readmission rate (22.6% versus 4.1%). Finally, a lower 5-year survival rate has also been observed in hemophilia patients than in the general population (91.9% versus 95.3%). In the last decade there have been dramatically positive improvements in implant designs and hematological treatment, and therefore it does not seem that THA in hemophilia is so far from that in osteoarthritic patients.

Patient Frailty is Correlated With Increased Adverse Events and Costs After Revision Total Hip Arthroplasty

BackgroundFrailty has been associated with poor outcomes and higher costs after primary total hip arthroplasty. However, frailty has not been studied in relation to outcomes after revision total hip arthroplasty (rTHA). This study examined the relationship between the Hospital Frailty Risk Score (HFRS), postoperative outcomes, and cost profiles following rTHA. MethodsIn this retrospective cohort study, we identified patients who underwent rTHA from January 2017 to November 2019 in the Nationwide Readmission Database. The 3 most frequently reported diagnosis codes for rTHA were then selected: dislocation; mechanical loosening; and infection. We calculated the HFRS for each patient to determine frailty status. We compared 30-day readmission rate, length of stay, and hospitalization cost between frail and nonfrail patients, using multivariate logistic and negative binomial regressions to adjust for covariates. We identified 36,243 total patients who underwent rTHA. Overall, 15,448 patients had a revision for dislocation, 11,062 for mechanical loosening, and 9,733 for infection. ResultsCompared to nonfrail patients, frail patients had higher rates of 30-day readmission, longer length of stay, and higher hospitalization cost. Frail patients had significantly higher rates of 30-day complication and 30-day reoperation. ConclusionsFrailty, measured using HFRS, is associated with increased postoperative complications and costs after rTHA. The HFRS has the ability to efficiently identify frail patients at-risk for perioperative complications enabling care teams to better focus optimization interventions on this patient cohort.

Impact of perioperative SARS-CoV-2 Omicron infection on postoperative complications in liver cancer hepatectomy: A single-center matched study

ObjectivesTo explore the effects of perioperative SARS-CoV-2 Omicron infection on postoperative complications in patients with liver cancer. MethodsA propensity-matched study was conducted, which included patients with primary liver cancer who underwent hepatectomy from September 01, 2022 to January 20, 2023. Patients who infected SARS-CoV-2 Omicron during the perioperative period (7 days before to 30 days after surgery) were matched 1:1 with noninfected patients. The primary outcomes, which were COVID-19-related major complications and liver resection-specific complications, were analyzed using multivariate logistic regression. ResultsA total of 243 patients were included, with 63 cases of perioperative infections, of which 62 were postoperative infections. The overall 30-day postoperative mortality rate was 1.6% (4/243). Compared to noninfected patients, those with perioperative infections showed no significant difference in the occurrence of adverse postoperative outcomes. However, they had a higher rate of 30-day readmission after surgery (11.1% vs 0%, P = 0.013). Perioperative SARS-CoV-2 infection was not associated with “major cardiorespiratory complications” or “liver resection-specific complications”, but age, pre-existing comorbidities, and tumor type were related to these outcomes. ConclusionPerioperative SARS-CoV-2 Omicron infection did not increase the incidence of postoperative complications in patients with liver cancer. However, those patients had a higher rate of 30-day readmission after surgery.

Patient Frailty is Correlated With Increased Adverse Events and Costs After Revision Knee Arthroplasty

BackgroundFrailty can predict adverse outcomes after various orthopaedic procedures, but is not well-studied in revision total knee arthroplasty (rTKA). We investigated the correlation between the Hospital Frailty Risk Score (HFRS) and post-rTKA outcomes. MethodsUsing the Nationwide Readmissions Database, we identified rTKA patients discharged from January 2017 to November 2019 for the most common diagnoses (mechanical loosening, infection, and instability). Using HFRS, we compared 30-day readmission rate, length of stay, and hospitalization cost between frail and nonfrail patients with multivariate and binomial regressions. The 30-day complication and reoperation rates were compared using univariate analyses. We identified 25,177 mechanical loosening patients, 12,712 infection patients, and 9,458 instability patients. ResultsFrail patients had higher rates of 30-day readmission (7.8 versus 3.7% for loosening, 13.5 versus 8.1% for infection, 8.7 versus 3.9% for instability; P < .01), longer length of stay (4.1 versus 2.4 days for loosening, 8.1 versus 4.4 days for infection, 4.9 versus 2.4 days for instability; P < .01), and greater cost ($32,082 versus $27,582 for loosening, $32,898 versus $28,115 for infection, $29,790 versus $24,164 for instability; P < .01). Frail loosening patients had higher 30-day complication (6.8 versus 2.9%, P < .01) and reoperation rates (1.8 versus 1.2%, P = .01). Frail infection patients had higher 30-day complication rates (14.0 versus 8.3%, P < .01). Frail instability patients had higher 30-day complication (8.0 versus 3.5%, P < .01) and reoperation rates (3.2 versus 1.6%, P < .01). ConclusionsThe HFRS may identify patients at risk for adverse events and increased costs after rTKA. Further research is needed to determine causation and mitigate complications and costs.

Knowing the Patient: Understanding Readmission Reasons in Complex Heart Failure.

Heart failure (HF) is a complex problem characterized by frequent hospitalizations and high 30-day readmission rates. Researchers studying HF readmission report that patients and clinicians have different perspectives on readmission and preventability when unadjusted for disease severity. The aim of this study was to gather patient, caregiver, nurse, and physician subjective reason(s) for 30-day HF readmission and perceptions of preventability with contextual factors to evaluate differences. A convergent, parallel, mixed-methods design was used with interviews and chart reviews to evaluate contextual factors from the current and index hospital stay. Adults readmitted within 30 days of a previous inpatient stay with a coded HF diagnosis were enrolled and interviewed, followed by interviews with associated caregivers, attending physicians, and assigned nurses. Interviews were conducted with patients (n = 44), caregivers (n = 6), physicians (n = 24), and nurses (n = 44). Readmissions were emergent/urgent (95%) and occurred within 14.9 days (SD, 8.1; 2-28 days) on average after discharge. Index stay coding revealed that most patients (73%) had a high severity of illness (73%) and risk of mortality (68%). Heart failure stage was inconsistently documented. Patients reported acute symptomatic reasons, with only 32% describing readmission as preventable. Physicians reported diagnostic reasons, 38% of which were preventable. Nurses reported behavioral reasons, with 59% being preventable. Patient/clinician agreement on readmission reason was low (30%). Patient/clinician perspectives on readmission varied among the patients with complex HF. Care planning based on HF stage and other contextual factors is needed to ensure a shared understanding of disease severity and a tailored symptom management approach to prevent readmission.

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.
