Implementation of the 300-mL Rule for the Management of Traumatic Hemothorax.

Traumatic hemothorax (HTX) is often managed with tube thoracostomy (TT); however, TT carries a high complication rate. In 2017, a guideline was implemented at our Level I trauma center to observe traumatic HTX ≤300mL in hemodynamically stable patients. We hypothesized that this guideline would decrease TT placement without increasing observation failure rates. This was a single-center retrospective review of all adult patients admitted with a HTX on computed tomography (CT) before (2015-2016) and after (2018-2019) the guideline implementation. Exclusion criteria were TT placement prior to CT scan, absence of CT scan, death within 5 days of admission, and a concurrent pneumothorax (PTX) >20mm. HTX volume was calculated using CT scan images and Mergo's formula: V=d 2xL (V: volume; d: depth; L: length). The primary outcome was observation failure, defined as the need for TT, video-assisted thoracoscopic surgery, thoracotomy after repeat imaging or worsening of symptoms and pulmonary morbidity. A total of 357 patients met inclusion criteria, of whom 210 were admitted after guideline implementation. There were no significant differences in baseline demographics, comorbidities, or injury characteristics across both cohorts. The post-implementation cohort had a significant increase in observation rate (75% vs 59%) and a decrease in TT placement (42% vs 57%). Moreover, the post-implementation group had a statistically significant shorter hospital (6 vs 8 days) and ICU (2 vs 3 days) LOS. No significant differences in observation failure, pulmonary complications, 30-day readmission, or 30-day mortality were observed across both cohorts. The implementation of the 300mL guideline led to a decrease in TT placement without increasing observation failure or complication rates. Level III, Therapeutic/Care Management.

Comparison of Outcomes for Patients Treated by Allopathic vs Osteopathic Surgeons

There are 2 degree programs for licensed physicians in the US: allopathic medical doctorate (MD) and osteopathic doctorate (DO). However, evidence is limited as to whether outcomes differ between patients treated by MD vs DO surgeons. To evaluate differences in surgical outcomes and practice patterns by surgeon medical school training (MD vs DO). This retrospective cohort study used 100% Medicare claims data from inpatient hospitals providing surgical services from January 1, 2016, to December 31, 2019 among Medicare fee-for-service beneficiaries aged 65 to 99 years who underwent 1 of the 14 most common surgical procedures. Data analysis was performed from January 17, 2023, to August 13, 2024. Medical school degree (MD vs DO). The primary outcome was 30-day mortality, and the secondary outcomes were readmissions and length of stay. To assess differences between surgeons by medical school training, a multivariable linear probability model was used, which was adjusted for hospital fixed effects and patient, procedure, and surgeon characteristics. Of the 2 360 108 total surgical procedures analyzed, 2 154 562 (91.3%) were performed by MD surgeons, and 205 546 (8.7%) were performed by DO surgeons. Of 43 651 total surgeons, most surgeons were MDs (39 339 [90.1%]), the median (SD) age was 49.0 (9.8) years, and 6649 surgeons (15.2%) were female. The mean (SD) age of patients undergoing surgical procedures was 74.9 (6.7) years, 1 353 818 of 2 360 108 patients (57.4%) were female, and 2 110 611 patients (89.4%) self-reported as White. DO surgeons were significantly more likely to operate on older patients (DO patient mean [SD] age: 75.3 [7.1] years; MD patient mean [SD] age: 74.8 [6.6]), female patients (DO: 60.2% of patients; MD: 57.1% of patients), and Medicaid dual-eligible patients (DO: 10.3% of patients; MD: 8.6% of patients). DOs performed a lower proportion of elective operations (DO: 74.2% vs MD: 80.2%) and were more likely to work in public hospitals (DO: 10.3%; MD: 9.5%) and nonteaching hospitals (DO: 57.9%; MD: 68.1%). There was no evidence that 30-day mortality differed between MD and DO surgeons (adjusted mortality rate, DO: 1.61%; MD: 1.58%; absolute risk difference [aRD], -0.04 percentage points; 95% CI, -0.11 to 0.04; P = .37). On secondary analyses, no difference was found in 30-day readmissions or length of stay between MD and DO surgeons. In this retrospective cohort study using Medicare data, there was no evidence that patient outcomes differed between MD and DO surgeons for common operations after adjusting for patient factors and practice settings.

Analysis of ERAS protocol adherence and postoperative outcomes after major colorectal surgery in a community hospital

Despite widespread adoption, the efficacy of Enhanced Recovery After Surgery (ERAS) protocols in community hospital settings remains understudied. This retrospective analysis conducted at a high-volume community hospital aimed to evaluate adherence to ERAS protocols and analyze postoperative outcomes following colorectal surgery. A total of 278 adult patients undergoing elective colorectal surgery between January 2022 and January 2024 were included. Data analysis revealed time to first mobilization proved to be satisfactory in accordance with ERAS hospital guidelines (mean 1.0 ​± ​0.05 days, range 0.1–13.8 days), and furthermore demonstrated a strong positive correlation with both time to first bowel function (r ​= ​0.69, p ​< ​0.0001) and length of stay (r ​= ​0.25, p ​< ​0.0001). Time to urinary catheter removal occurred slightly after guideline-directed removal (mean 1.1 ​± ​0.05 days, range 0.5–12.9 days), however did exhibit a significant positive correlation with length of stay (r ​= ​0.33, p ​< ​0.0001). 10.9 ​% of patients experienced a postoperative complication, while the average length of stay across all procedures was 3.1 ​± ​0.17 days (range 0.9–23.3 days), and the overall 30-day readmission rate stood at 10.43 ​%. This study underscores the need for ongoing evaluation and refinement of ERAS protocols in community hospital settings to enhance surgical care and patient satisfaction.

Influence of patient characteristics and discharge destination on circulatory system diseases readmissions among older heart failure patients

IntroductionHeart failure (HF) prevalence is rising, particularly among older people, constituting a significant cause of hospitalization. Discharge destinations, including nursing homes (NH), play a crucial role in post-hospitalization outcomes but remain underexplored. MethodsA retrospective study utilizing the Spanish National Health System's Minimum Basic Data Set identified older HF patients (≥75 years) discharged from acute hospitals between 2016 and 2019. Patient demographics, comorbidities, and discharge destinations were analyzed. Predictors of 30-day readmissions for circulatory system diseases and NH admission were assessed using multilevel logistic regression models. ResultsOf 157,330 index episodes, 2.8 % were discharged to NH, more frequently in females. Thirty-day readmission incidence was 9.3 %, with HF exacerbations accounting for 80.6 % of cases. Predictors of 30-day readmission included renal failure (OR: 1.38), severe hematological disorders (OR: 1.30), and history of coronary revascularization surgery (OR: 1.23), while discharge to NH lowered the risk (OR: 0.70). Admission to NH was associated with neurological diseases (OR: 3.27), cardiogenic shock (OR: 3.19), stroke (OR: 2.68), advanced cancer (OR: 2.51), with higher likelihood among females (OR: 1.23). After propensity score-matched analysis, patients discharged to NH had significantly lower 30-day readmission rates than those discharged home (6.4 % vs. 28.9 %, adjusted OR: 0.169). ConclusionDischarge to NH is infrequent but associated with lower readmission risk for older HF patients. Female gender, specific comorbidities, and acute conditions influence NH admission. Enhanced collaboration between HF units and NH is crucial for optimizing post-hospitalization outcomes. Further research and policy initiatives are needed to improve care coordination and reduce HF readmissions.

The total joint arthroplasty care patterns in China during the COVID-19 pandemic: a multicenter cohort study

BackgroundThe COVID-19 pandemic has profoundly affected the care practices of total joint arthroplasty (TJA) throughout the world. However, the impact of the pandemic on TJA care practices has not yet been studied in China.MethodsThis retrospective multicenter cohort included patients aged 18 years or older who underwent TJA between January 2019 and December 2019 (prepandemic period) and January 2020 to December 2021 (pandemic period). Data were obtained from the medical records of 17 Chinese hospitals. Interrupted time series (ITS) analysis was used to estimate differences in monthly TJA volume, hospitalization proportion of TJA, preoperative characteristics, postoperative complications, 30-day readmissions, length of stay (LOS), and costs in inpatients undergoing TJA between the prepandemic and pandemic periods. Multivariate regression and propensity score matching (PSM) analyses were used to assess the impact of the COVID-19 pandemic on hospital complications, readmissions at 30 days, LOS, and costs at the patient level.ResultsA total of 752,477 inpatients undergoing TJA in the prepandemic period, 1,291,248 in the pandemic period, with an average 13.1% yearly decrease in the volume of TJA during the pandemic. No significant changes were observed in the proportion of hospitalizations for TJA. ITS analyses showed increases in the proportion of comorbidities (8.5%, 95% CI: 3.4–14.0%) and the number of comorbidities (15.6%, 95% CI: 7.7–24.1%) in TJA cases during the pandemic, without increasing LOS, costs, complications, and readmission rates. Multivariate and PSM analyses showed 6% and 26% reductions in costs and readmission rates during the pandemic, respectively.ConclusionsThe COVID-19 pandemic was associated with more severe preoperative conditions and decreased volume, costs, and readmission rates in patients undergoing TJA in China. These findings demonstrate that the COVID-19 pandemic did not have a dramatic impact on the TJA care pattern in China, which may have resulted from active and strict strategies in combating COVID-19 as well as a rapid response in hospital management.

Remdesivir Effectiveness in Reducing the Risk of 30-day Readmission in Vulnerable Patients Hospitalized for COVID-19: A Retrospective US Cohort Study Using Propensity Scores.

Reducing hospital readmission offer potential benefits for patients, providers, payers, and policymakers to improve quality of healthcare, reduce cost, and improve patient experience. We investigated effectiveness of remdesivir in reducing 30-day COVID-19-related readmission during the Omicron era, including older adults and those with underlying immunocompromising conditions. This retrospective study utilized the US PINC AI Healthcare Database to identify adult patients discharged alive from an index COVID-19 hospitalization between December 01, 2021 and February 29, 2024. Odds of 30-day COVID-19-related readmission to the same hospital were compared between patients who received remdesivir vs those not, after balancing characteristics of two groups using inverse probability of treatment weighting (IPTW). Analyses were stratified by maximum supplemental oxygen requirement during index hospitalization. Of 326,033 patients hospitalized for COVID-19 during study period, 210,586 patients met the eligibility criteria. Of these, 109,551 (52%) patients were treated with remdesivir. After IPTW, lower odds of 30-day COVID-19-related readmission were observed in patients who received remdesivir vs those who did not, in the overall population (3.3% vs 4.2%, respectively; odds ratio [95% confidence interval]: 0.78 [0.75-0.80]), elderly population (3.7% vs 4.7%, respectively; 0.78 [0.75-0.81]), and those with underlying immunocompromising conditions (5.3% vs 6.2%, respectively; 0.86 [0.80-0.92]). These results were consistent irrespective of supplemental oxygen requirements. Treating patients hospitalized for COVID-19 with remdesivir was associated with a significantly lower likelihood of 30-day COVID-19-related readmission across all patients discharged alive from the initial COVID-19 hospitalization, including older adults and those with underlying immunocompromising conditions.

Association between hospital type and length of stay and readmissions for young adults with complex chronic diseases.

There is a paucity of information around whether hospital length of stay and readmission rates differ based upon hospital type for adolescents and young adults (AYA) with complex chronic diseases (CCDs). To measure the association between hospital type and readmission rates and index admission LOS among AYA with CCDs. We performed a retrospective cross-sectional study of 2017 Healthcare Cost and Utilization Project State Inpatient Databases, including patients 12-25 years old with cystic fibrosis (CF), sickle cell disease (SCD), spina bifida (SB), inflammatory bowel disease (IBD), and diabetes mellitus (DM). Index hospitalizations were categorized by hospital type (pediatric hospitals [PHs], adult hospitals with pediatric services [AHPSs], and adult hospitals without pediatric services [AHs]), CCD, and age group. We compared case-mix adjusted 30-day readmission rates and differences in index admission LOS between hospital types. Adult hospitals without pediatric services exhibited higher readmission rates (25.4%) than AHPS (22.9%) and PH (15.1%). Compared to patients with CF admitted to AH, lower readmission rates were associated with longer LOS at both AHPS (relative ratio [RR]: 1.25, 95% confidence interval [CI]: 1.02-1.55) and PH (RR: 1.59, 95% CI: 1.28-1.97). Patients with DM admitted to AHPS (odds ratio [OR]: 0.75, 95% CI: 0.62-0.91) and PH (OR: 0.47, 95% CI: 0.31-0.71) also demonstrated lower readmission rates than those admitted to AH. For AYA with CCD, hospital type is associated with differences in readmission rates and LOS. Lower readmission rates at hospitals with pediatric services compared to adult hospitals without pediatric services suggest hospital type has a significant impact on outcomes.

Routine Use of Indwelling Urinary Catheters During Endovascular Abdominal Aortic Aneurysm Repair is Not Necessary.

Endovascular infra-renal abdominal aortic aneurysm repair (EVAR) has proven to be an effective, less invasive alternative to open aortic aneurysm repair with decreased 30-day mortality. Historically, urinary drainage catheters were routinely placed preoperatively before EVAR in our institution. A shift to reduced catheter placement has occurred in conjunction with percutaneous EVARs becoming more routine. Urethral catheterization carries risk of infection (UTI), urinary retention and prostatic trauma inducing hematuria. The purpose of this study was to evaluate whether avoidance of urinary catheter placement during EVAR is an effective practice to reduce cost and morbidity. This was a single-institution, retrospective review of 177 consecutive patients who underwent elective infrarenal EVAR. Ruptured aneurysms and emergent EVAR were excluded. The study end points were postoperative UTI, urinary retention, length of stay, and readmission within 30 days. Univariable analysis was performed for these four outcomes in patients with (N = 92 and without (N = 65) preoperative urinary catheter placement. A more expansive multivariable investigation for risk of urinary retention following EVAR was conducted with binary logistic regression with co-variates including age, sex, femoral cutdown, estimated blood loss (EBL), urinary catheter, congestive heart failure, diabetes, and postoperative urinary retention as co-variates. Patients who had a Urinary catheter placed had an over two fold higher event rate of urinary retention (10.9% vs 4.6%) This urinary retention trend lacked power to reach significance (OR 2.52 (.665-9.55). Placement of urinary catheter also had a strong trend towards increased rate of UTI but lacking power for significance (7.6% vs 3.10%, OR 1.96 (.556-6.57). There was no difference with or without urinary catheter placement regarding 30-day readmission (yes catheter 7.6% vs no catheter 6.2%, P = .725), or length of stay (yes catheter 2.13 days vs no catheter 1.74 days, P = .723). Urinary retention was significantly associated with the development of a UTI with 23% of patients who had retention developing UTI compared with 4.2% of patients without retention developing UTI (adjusted odds ratio = 17.98, P = .019). Increased blood loss (P = .027) was also associated with increased rate of UTI on multivariable analysis. Avoidance of preoperative urinary catheter placement displays a trend towards avoiding urinary retention and UTI. Patients who develop post EVAR urinary retention experience a significantly increased rate of UTI. Selective urinary catheter placement should be used to help reduce urinary-related complications following elective EVAR.

Association of robotic surgery with early discharge, readmission, and complications in elective colectomy: an analysis of NSQIP data from 2012 to 2021.

Background Early discharge (ED) after colectomy has become a target outcome for multiple reasons, but the factors associated with ED are not well characterized. This study investigated the factors associated with ED and evaluated the impact of ED on overall outcome. Methods Data from ACS-NSQIP were used to identify patients who underwent non-emergent colectomy from 2012 to 2021. ED was defined as length of stay ≤ 2days. Unpaired t-tests, chi-square tests and adjusted multivariate logistic regression modeling were used to estimate associated factors for ED. Bounceback readmission was defined as readmission within 7days of discharge. Results In this cohort of 282,490 patients, 43,137 (15.3%) met the criteria for ED. Robotic colectomy (OR 14.35; 95% CI [13.63-15.12]) was more strongly associated with ED than any other patient characteristic, including laparoscopic colectomy (6.82 [6.51-7.14], ref open colectomy). ED vs. non-ED patients had lower rates of 30-day (5.84 vs. 10.37%, p < 0.01) and bounceback (3.56 vs. 5.75%, p < 0.01) readmissions, overall complications (5.65 vs. 18.63%, p < 0.01) and post-discharge complications (4.21 vs. 7.49%, p < 0.01). Conclusions Robotic surgery was the variable most strongly associated with ED, with greater odds of ED compared to both laparoscopic and open colectomy. Patients who had ED after robotic surgery had lower rates of complications and readmission compared to non-ED patients.

Metabolic syndrome increases the length of stay and medical complications after hip and knee arthroplasty: results from a prospective cohort study of 2,901 patients.

Metabolic syndrome (MetS) affects more than 60% of the patients having a hip or knee arthroplasty due to osteoarthritis. As it is debated whether metabolic syndrome increases the risk of complications, we aimed to investigate the length of stay (LOS) and risk of readmission at 30 and 90 days after surgery, including causes of readmission. We conducted a prospective cohort study of 2,901 patients undergoing hip and knee arthroplasty from May 2017 to November 2019. Physical examination, blood samples, and medical history from national registries determined the diagnosis of metabolic syndrome from the International Diabetes Federation definition. We used multivariate linear regression to investigate differences in LOS according to MetS, and binary regression to investigate the risk and causes of readmission within 30 and 90 days, including 95% confidence intervals (CI) and P values. Patients with MetS showed a slightly longer LOS (0.20 days, CI 0.10-0.29) and had an increased risk of readmission within 90 days (adjusted relative risk [RR] 1.2, CI 1.0-1.4; P = 0.02), but not within 30 days (adjusted RR 1.1, CI 0.9-1.4; P = 0.3) after surgery. Cardiovascular disease was the dominant cause of readmission. Although patients with MetS do not experience a clinically relevant longer LOS after hip and knee arthroplasty, they have an increased risk of 90-day readmission mainly due to cardiovascular complications, which should be considered when planning surgical care in this group of patients.

Reducing readmissions with pharmacist-integrated care in Medicare value-based programs.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Pharmacy transitions of care (ToC) programs have been shown to decrease 30-day hospital readmissions and improve patient outcomes, but there is limited published data on the impact of pharmacist-integrated ToC services beyond 30 days. The objective of this study was to evaluate the impact of pharmacist-integrated ToC and population health services on 30-, 60-, and 90-day all-cause readmissions in a Medicare value-based program (MV-BP) population and to compare mean times to first readmission with and without pharmacist care. A retrospective observational chart review was conducted to identify eligible hospital discharge encounters (DEs). Patients 18 years of age or older enrolled in an MV-BP were assigned to 4 study groups (a control group or one of 3 intervention arms) based on the pharmacy ToC services they received from either an inpatient ToC pharmacist or a dedicated population health pharmacist (PHP). Among 1,065 eligible DEs, 90-day follow-up was completed in 1,039 cases. The control group (n = 213) had a 90-day readmission rate of 34.74%. Intervention arm 1 (n = 201) had no significant reduction in 90-day readmissions, with a rate of 29.85% (odds ratio [OR], 0.94; 95% CI, 0.61-1.47; P = 0.80), while intervention arms 2 (n = 209), and 3 (n = 416) had significantly lower rates of readmission: 9.57% (OR, 0.26; 95% CI, 0.15-0.46; P < 0.01), and 17.07% (OR, 0.41; 95% CI, 0.27-0.61; P < 0.01), respectively. A combination of ToC and PHP services reduced 30-, 60-, and 90-day readmission rates in an MV-BP population. These results support the expansion of pharmacy-based ToC to minimize readmissions within 90 days for this Medicare population.

Are all robotic technologies created equal? Comparing one of the latest image-free robotic technologies to all other robotic systems for total knee arthroplasty

BackgroundRobotic-assisted technologies have been developed to increase surgical precision and reduce surgical variability in total knee arthroplasty (TKA). Several different robotic systems have been introduced in the last decade for TKA. The DePuy Synthes VELYS™ Robotic-Assisted Solution (VRAS) is an imageless system designed to eliminate the need for preoperative CT scans and is one of the latest entrants in the rapidly evolving field of robotic technology in TKA. This study compared the clinical and economic outcomes associated with VRAS and other robotic-assisted technologies for primary TKA.MethodsA retrospective cohort study using the Premier Healthcare Database included patients who underwent primary TKA with VRAS or other robotic-assisted technologies from January 1, 2022, to April 30, 2023. The primary outcome for the study was hospital follow-up visits (revisits) within 90 days post-TKA. Secondary outcomes included readmission and revision rates within 90 days post-TKA, operating room time, length of stay, discharge status and hospital costs. Cohorts were balanced using propensity score fine stratification, and generalized linear models were constructed to evaluate outcomes.ResultsThis study included 827 VRAS TKA patients and 16,428 TKA patients treated with other robotic-assisted technologies. The 90-day all-cause and knee-related revisit rates were significantly lower for VRAS than for other robotic-assisted technologies (all-cause 13.9% vs. 22.8% and knee-related 2.8% vs. 5.4%, respectively; p value < 0.01). The all-cause and knee-related 90-day readmission rates were also lower for VRAS, although the differences were not statistically significant. The 90-day revision rates were similar for VRAS and other robotic-assisted technologies (0.48% vs. 0.45%), as was the operating room time (138 vs. 137 min). The 90-day knee-related cost for the VRAS cohort was $15,048 compared to $16,867 for other robotic technologies.ConclusionsThis database study demonstrated that early postoperative revisit rates and total cost of care are lower for VRAS than for all other robotic-assisted technologies for TKA, while operating room time and discharge status were similar. These are important findings in ever-evolving healthcare systems that are increasingly cost conscious and cognizant of principles associated with value-based care.

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.

Leaving Against Medical Advice From Children's Hospitals.

Leaving the hospital against medical advice (AMA) reflects a breakdown in the family-clinician relationship and creates ethical dilemmas in inpatient pediatric care. There are no national data on frequency or characteristics of leaving AMA from US children's hospitals. We performed a retrospective cohort study of hospital discharges for children under 18 years old from January 1, 2018 to December 31, 2022 in 43 children's hospitals in the Pediatric Health Information System (PHIS) database. The primary outcome was leaving AMA. Exposures were demographic, geographic, and clinical characteristics. We used multivariable mixed effects logistic regression models to assess independent factors associated with leaving AMA and all-cause 14-day hospital readmission. Among 3 672 243 included inpatient encounters, 2972 (0.08%) ended in leaving AMA. Compared with non-Hispanic white patients, non-Hispanic Black patients had higher odds of leaving AMA (adjusted odds ratio [aOR] 1.31 [95% confidence interval (CI) 1.19-1.44]), whereas Hispanic patients (aOR 0.66 [95% CI 0.59-0.75]) had lower odds of leaving AMA. Hospitalizations for patients with noncommercial insurance were more likely to end in leaving AMA. Leaving AMA was associated with increased odds of 14-day inpatient readmission (aOR 1.41 [95% CI 1.24-1.61]) compared with patients who did not leave AMA. There was substantial interhospital variability in standardized rates of leaving AMA (range 0.18-2.14 discharges per 1000 inpatient encounters). Approximately 1 in 1235 inpatient encounters ended in leaving AMA. Non-Hispanic Black patients had increased odds of leaving AMA. Leaving AMA was associated with increased odds of 14-day readmission.

Clinical outcomes of children with COVID-19 and appendicitis: a propensity score matched analysis.

Early in the COVID-19 pandemic, many children with appendicitis and COVID-19 were initially treated non-operatively and later underwent interval appendectomy. Currently, children with both appendicitis and COVID-19 frequently undergo upfront appendectomy. The impact of this return to upfront surgical management on patient outcomes is unknown. This study compared outcomes of pediatric patients with and without COVID-19 infection undergoing appendectomy. A retrospective cohort study of children < 21y who underwent appendectomy from 3/19/2020 to 7/31/2022 at 50 Pediatric Health Information System children's hospitals was conducted. Children with documented COVID-19 were identified. Exclusions included preoperative ventilator or supplemental oxygen dependence, and missing data. To evaluate COVID-19 positive versus COVID-19 negative patients, we used a propensity score matched on sociodemographics, comorbidities, laparoscopy, perforation, and hospital. Chi-square and Mann-Whitney U tests identified differences between groups in length of stay, postoperative drain placement, 30-day re-admission, and mechanical ventilation requirements. Overall, 51,861 children of median age 11y (IQR: 8-14) underwent appendectomy, of whom 1,440 (2.3%) had COVID-19. Most were male (60.3%), White (72.1%) and non-Hispanic (61.4%). Public insurance was the most common (47.5%). We created a matched cohort of 1,360 COVID-19 positive and 1,360 COVID-19 negative children. Children with COVID-19 had shorter hospitalizations (1d, IQR: 1-4 vs. 2d, IQR: 1-5, p = 0.03), less postoperative peritoneal drain placement (2.4% vs. 4.1%, p = 0.01), and fewer 30-day readmissions (9.0% vs. 11.4%, p = 0.04). However, no difference in incidence or duration of mechanical ventilation (p > 0.05) was detected. Our findings suggest that upfront appendectomy for children with appendicitis and COVID-19 has similar outcomes compared to children without COVID-19. Level III.

A time-series analysis examining implementation strategies to increase use of an early-supported discharge hospital at home model.

Early-supported discharge (ESD) hospital-at-home (HaH) programs facilitate hospitalized patients to receive ongoing acute-level care at home, thereby promoting patient-centeredness while improving hospital throughput. The current study aimed to test multiple implementation strategies to increase and sustain HaH ESD utilization. We conducted interrupted time series analyses to evaluate the effectiveness of implementation strategies on weekly HaH ESD referrals and capacity utilization at five hospitals. Intervention 1 included provider-focused education and HaH nurse navigator support (July 2021 to May 2022). Intervention 2 added provider-level referral performance feedback and daily electronic health record-based eligibility reports (May 2022 to December 2022). During postintervention (January 2023 to June 2023), implementation strategies were no longer supported by the study team. Clinical outcomes were assessed over time and between patient subgroups. There were 5951 HaH ESD patients overall. After Intervention 2, we observed immediate increases in weekly HaH ESD referrals (level change mean difference [MD, 95% confidence interval]: 14.8, 5.9-23.6) and capacity utilization (level change MD: 13.9%, 6.2%-21.5%) and additional week-to-week increases in capacity utilization (slope change MD: 0.6%, 0.2%-0.9%), compared to Intervention 1 trends. HaH ESD referrals and capacity utilization were sustained postintervention. The proportion of provider-initiated referrals increased over time (Intervention 1: 79.4%, Intervention 2: 90.9%, postintervention: 95.2%). As HaH ESD utilization increased, we observed shorter inpatient length of stay and fewer HaH ESD encounters per visit (p < 0.01). There were small, statistically significant differences in 30-day mortality and readmission for residents of rural and socioeconomically disadvantaged areas. Applying referral-focused provider feedback and daily eligibility reports were effective within a multicomponent approach to increase and sustain HaH ESD utilization.

Incidence and predictors of unplanned 30-day hospital readmissions among heart failure patients in Ethiopia: a 5-year retrospective cohort study

The burden of heart failure increases over time and is a leading cause of unplanned readmissions worldwide. In addition, its impact has doubled in countries with limited health resources, including Ethiopia. Identifying and preventing the possible contributing factors is crucial to reducing unplanned hospital readmissions and improving clinical outcomes. The study aimed to assess the incidence and predictors of 30-day unplanned readmission among heart failure patients at selected South Wollo general hospitals in 2022. A hospital-based retrospective cohort study design was employed from January 1, 2016, to December 30, 2020. The data was collected from 572 randomly selected medical records using data extraction checklists. Data were entered in Epi-Data version 4.6 and analyzed with Stata version 17. The Kaplan–Meier and log-rank tests were used to estimate and compare the survival failure time. A Cox proportional hazard analysis was used to identify the predictors of readmission. The statistical significance level was declared at a p-value < 0.05 with an adjusted odds ratio and a 95% confidence interval. A total of 151 (26.40%) heart failure patients were readmitted within 30 days of discharge. Among the study participants, 302 (52.8%) were male, and 370 (64.7%) were rural residents. The mean age was 45.8 ± 14.1 SD years. In the multivariate Cox proportional hazards analysis being an age (> 65 years) (AHR: 3.172, 95% CI:.21, 4.55, P = 0.001), rural in residency (AHR: 2.47, 95%CI: 1.44, 4.24, P = 0.001), Asthma or Chronic Obstructive Pulmonary Disease (AHR: 1.62, 95% CI: 1.11, 2.35, P = 0.012), HIV/AIDS (AHR: 1.84, 95%CI: 1.24, 2.75, P = 0.003), Haemoglobin level 8–10.9 g/dL (AHR: 6.20, 95% CI: 3.74, 10.28, P = 0.001), and Mean platelet volume > 9.1 fl (AHR: 2.08, 95% CI: 1.27, 3.40, P = 0.004) were identified as independent predictors of unplanned hospital readmission. The incidence of unplanned hospital readmission was relatively high among heart failure patients. Elderly patients, rural residency, comorbidity, a higher mean platelet volume, and a low hemoglobin level were independent predictors of readmission. Working on these factors will help reduce the hazards of unplanned hospital readmission.

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.

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.

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
