Medicare’s comprehensive care for joint replacement model increased public hospitals' inpatient length of stay

BackgroundThe Comprehensive Care for Joint Replacement (CJR) model is an alternative Medicare payment model for joint replacement that mandated participation by hospitals in randomly selected Metropolitan Statistical Areas (MSAs). On average, the program decreased inpatient length of stay and increased home discharge rates. It is unclear if these effects differed based on hospital ownership type, even though ownership may impact care redesign opportunities.MethodsWe used the 2014–2017 California Patient Discharge Datasets. The study included 113,590 hospitalizations for hip and knee joint replacement from 287 hospitals in the treated and control MSAs in California. The primary outcomes were inpatient length of stay and home discharge rates. Home discharge status included self-care, the use of home health, and hospice care at home. To determine whether the impact of the CJR model differed by hospital ownership type, we used event study, difference-in-differences (DID), and triple differences (DDD) models to estimate changes in health care services utilization in treated relative to control areas before versus after CJR implementation (April 2016) by hospital ownership type.ResultsOf the 113,590 hospitalizations, 51,708 (45.52%) were in treated MSAs and 61,882 (54.48%) were in control MSAs; 81,649 (71.88%) were from nonprofit hospitals, 20,247 (17.82%) were from for-profit hospitals, and 11,694 (10.29%) were from government-owned hospitals. DID analyses showed that after policy implementation, nonprofit and for-profit hospitals experienced a decrease in inpatient length of stay of 0.02 days (95% CI, -0.04 to -0.01) and 0.04 days (95% CI, -0.06 to -0.01), respectively, while government-owned hospitals experienced an increase by 0.11 days (95% CI, 0.04 to 0.18). For home discharge rates, nonprofit hospitals experienced an increase of 0.02 (95% CI, 0.01 to 0.03), while other hospitals did not show statistically significant changes. DDD analyses confirmed that inpatient length of stay increased in public compared to nonprofit hospitals in treated relative to control MSAs after policy implementation.ConclusionsThe impacts of the CJR program differed by hospital ownership type. Government-owned hospitals, with their unique financial circumstances, may have faced challenges that hindered the reductions in inpatient length of stay observed in other types of hospitals under the CJR Model.

What Perioperative Factors Are Associated With High-risk Daily Morphine Milligram Equivalent Totals in Spinal Decompressions?

Retrospective cohort analysis. To determine what factors are associated with high-risk daily morphine milligram equivalent (MME) totals in patients undergoing spinal decompression. Daily dosages of ≥100 MME/d are associated with an almost 9-fold increased risk of overdose. Current general recommendations endorse the lowest effective dose and ≤50 MME/d. Retrospective analysis was conducted on 260 patients who underwent spinal decompressive surgery. Average MME/d was calculated as the sum of qualifying inpatient MMEs administered divided by the sum of inpatient length of stay. Independent variables across demographic, clinical, and surgical domains were subject to comparative and logistic regression analysis. Overall MME per day was 54.19 ± 39.37, with a range of 1.67-218.34 MME/d. Sixty-six patients were determined to have "high-risk MME." These patients were significantly younger (58.8 ± 13.1 vs 70.53 ± 11.5; P < 0.001) and reported higher preoperative pain visual analog scale (VAS; 4.8 ± 3 vs 2.8 ± 3.3; P = 0.0021) than the patients at low risk. In addition, high-risk patients had significantly higher body mass indexes (BMIs; P < 0.05) and received ketamine as part of anesthesia (P < 0.05). Patients who consumed high-risk dosages of MMEs in the perioperative period were more likely to have been on opioids before surgery and to report higher pain scores at 4-6 week follow-ups (P < 0.05). The final logistics regression model identified independent risk factors to be younger age, higher BMIs and preoperative VAS, and prior use of opioids and intraoperative ketamine. Patients with high MME per day who underwent spinal decompression were significantly younger with higher BMIs and preoperative VAS with an increased incidence of preoperative opioid use and intraoperative ketamine. A closer look at interaction models revealed that a combination of high preoperative pain and intraoperative ketamine usage were at a significantly increased risk of higher MME consumption. Preoperative opioid risk education and mitigation strategies should be considered in patients with high MME risk, especially in younger patients already utilizing opioids before surgery.

The role of cannabis on total hip and knee surgeries outcomes: a systematic review and meta-analysis.

Cannabis refers to medications derived from the Cannabis plant. Cannabis has long been used to treat a wide range of conditions. The widespread legalization of cannabis has increased its use. This meta-analysis evaluates the effects of preoperative cannabis usage on TKA and THA outcomes and complications. This review follows CRD Guidance for Undertaking Reviews in Healthcare and PRISMA 2020 guidelines. On October 12, 2023, we extensively searched MEDLINE (PubMed), Scopus, Cochrane Central Register of Controlled Trials, and Web of Science. There were no time, place, or language restrictions. We also examined the references and citations in the included publications to find relevant research. We found 208 references in PubMed/Medline, Scopus, Web of Science, and other databases. After reviewing all publications, we identified 18 references that match the requirements for further assessment. The odds ratios (ORs) for reoperation and readmission are 1.35 (95% CI: 0.69, 2.66, and p-value = 0.38), and 0.89 (95% CI: 0.41, 1.92, and p-value = 0.76). Inpatient morphine milligram equivalent (MME) and length of stay (LOS) have a mean difference (MD) of -1.71 (95% CI: -13.46, 10.05, and p-value = 0.78), and - 0.13 (95% CI: -0.33, 0.08, and p-value = 0.23). The MD of the VAS pain score 24-72h after surgery is 0.40 (95% CI: -0.07, 0.87, and p-value = 0.10). The odds ratio for PTE and DVT is 1.54 (95% CI: 0.1, 23.24, and p-value = 0.75), and 1.38 (95% CI: 1.08, 1.77, and p-value = 0.01), respectively. Cannabis users experienced significantly higher rates of DVT following THA and TKA. Our subgroup analysis found that cannabis users who underwent TKA had considerably higher rates of reoperation (p-value = 0.10) and readmission (p-value ≤ 0.01), while those who underwent THA had significantly lower rates of PTE. These findings highlight the need to include cannabis use as a risk factor in surgical planning and patient care protocols, and further studies are warranted. This study design and protocol were performed in accordance with the PRISMA Statement. The protocol was registered previously on PROSPERO CRD42024551078.

Changes in Healthcare Utilization in Japan in the Aftermath of the COVID-19 Pandemic: A Time Series Analysis of Japanese National Data Through November 2023.

The COVID-19 pandemic precipitated substantial disruptions in healthcare utilization globally. In Japan, reduced healthcare utilization during the pandemic's early phases had been documented previously. However, few studies have investigated the impact of the pandemic's later stages (2022-2023) on healthcare utilization rates, particularly in the Japanese context. We employed a quasi-Poisson regression model, adapted from the FluMOMO framework, to analyze temporal trends in Japanese healthcare utilization throughout the pandemic until November 2023. We estimated inpatient and outpatient volumes and hospital length of stay by bed type (general and psychiatric). In general hospital beds, inpatient volumes remained significantly below pre-pandemic levels for every month until November 2023, with a reduction of 7.8 percent in 2023 compared to pre-pandemic levels. Psychiatric inpatient volumes, which had been declining before the pandemic, continued this downward trend, with the average occupancy rate decreasing by approximately 5.3% to 81.3% in 2023 compared to pre-pandemic levels. Significantly reduced outpatient volumes for both general and psychiatric care, in addition to prolonged lengths of hospital stay for psychiatric beds, were observed sporadically for several months in 2022 and 2023, persisting beyond the cessation of state of emergency and quasi-state of emergency declarations. The COVID-19 pandemic fundamentally altered healthcare utilization patterns in Japan. We observed a sustained reduction in general and psychiatric inpatient volumes relative to pre-pandemic baselines nationwide. The prolonged impact on healthcare utilization patterns, persisting beyond emergency measures, warrants continued monitoring of service delivery.

BIOS-01. MACHINE LEARNING-BASED PREDICTION OF INPATIENT CARE COSTS FOR PATIENTS WITH BRAIN METASTASES: A REAL-WORLD ANALYSIS

Abstract INTRODUCTION Brain metastases (BMs) are increasingly a cause of significant cancer-related morbidity, mortality, and economic burden. While BM-related healthcare costs have been previously described, predictive analytics based on contemporary cohorts, particularly for inpatient care, remain unavailable. This study sought to evaluate inpatient care costs (IPCC) and associated reimbursements for patients with BMs and perform predictive modeling through supervised machine learning (sML) using a contemporary, commercial US claims database. METHODS This retrospective study, reported following STROBE and TRIPOD+AI reporting guidelines, included adult patients (aged 18-65 years) in the United States (US) with BMs included in the MarketScan Commercial Claims and Encounters Database who received inpatient care during January 2016 to December 2021. Eligible patients were identified using ICD-10 codes. IPCC measures were adjusted using the Medical Care component of the 2023 Consumer Price Index. The primary study outcome was total IPCC, represented by adjusted gross total payments. After log-transformation performed due to data skew, sML was carried out using Random Forest algorithm with 1000 iterations with a 70:30 training-test data split, followed by residual analysis and evaluation of predictive performance using root-mean-squared error (RMSE), out-of-bag error (OOBE), and calibration curve. Multivariable linear regression was carried out for sensitivity analyses. RESULTS A total of 25117 unique inpatient admissions across 13477 BM patients were included, with median (IQR) age of 57 years (51-61). Gross median (IQR) CPI-medical-care-adjusted values per admission were: total payments $28,119.51 (16847.45-55111.67); hospital payments $24,678.74 (14601.66-47864.84); and payments to principal physician $884.80 (441.07-2434.15), being 3.6% (IQR 1.9-6.8) of total payment. Median inpatient length of stay was 4 days (IQR 2-8). ML model had an OOBE of 0.61 and, using test data, RMSE of 0.85, indicating robust performance. No major deviations were found on residual analysis. CONCLUSIONS Contemporary IPCCs for BM patients in US are substantial but driven minimally by payments to principal physician. sML may be utilized to successfully predict IPCC for BM patients.

A parallel-group randomized controlled trial of blue light versus red light for improving sleep, fatigue, and cognition following stroke: Pilot results and recommendations for further study

BackgroundDisordered sleep and fatigue are common in the acute phase of stroke and can impede recovery. ObjectiveA randomized parallel group placebo-controlled pilot study compared daily morning exposure to blue light or red light (placebo) for improving daytime sleepiness, fatigue, nocturnal sleep, and cognition in patients receiving inpatient rehabilitation for acute stroke. Methods43 patients with disordered sleep secondary to first episode stroke (n = 34 ischemic, n = 9 hemorrhagic; aged 66.2 ± 14.1 years) were randomized to receive 25 min of blue or red light for 5 or more days depending on inpatient rehabilitation length of stay (blue-light n = 21, red-light n = 22). At baseline and study discharge, daytime sleepiness was measured with the Karolinska Sleepiness Scale and Wits Pictorial Sleepiness Scale, fatigue with a visual analogue scale, and cognitive function with the Rey Auditory Verbal Learning Test and Trail Making Test (TMT). Wrist actigraphs measured nocturnal sleep parameters. Effect sizes were used to estimate sample sizes for larger studies. ResultsBlue light exposure led to significant improvements in daytime sleepiness, fatigue, auditory verbal learning, and time to sleep onset (all p < .05) relative to red light exposure (effect size range 0.75 to 1.83). Change in TMT, minutes of nocturnal sleep, and number of awakenings after sleep onset were not statistically significant (effect sizes range 0.38 to 0.57). ConclusionMorning blue light exposure for 5 or more days after acute stroke led to greater improvements than red light exposure. Effect sizes suggest a larger study is warranted to confirm generalizability of pilot findings.Trial Registration:ClinicalTrials.govNCT03125967 (Registered 01/01/2017).

Inpatient Falls: Epidemiology, Risk Assessment, and Prevention Measures. A Narrative Review.

Background Patient falls are a common inpatient dilemma and comprise the largest category of preventable adverse events in hospitalized patients. These events place a clinical burden on the patient, such as increased morbidity and reduced quality of life, in addition to an economic burden on the hospital system. Fall prevention strategies have the opportunity to decrease inpatient health care costs and length of stay. Several risk factors have been identified that contribute to inpatient falls and several strategies have been identified to minimize this risk. These risk factors are typically characterized as intrinsic and extrinsic factors. Intrinsic factors include characteristics such as age, gender, impaired mobility, and physiological factors (eg, co-morbidities, low muscular strength, visual impairment, poor reaction time, and movement disorders). Extrinsic factors are related to characteristics in the environment, such as slippery surfaces, footwear, bad lighting, and the influence of medications. Risk assessment tools, such as the Hendrich II Fall Risk Model, Morse Fall Scale, and STRATIFY, were developed to help identify those at risk. In utilizing these models and our understanding of predisposing risk factors, prevention strategies may be utilized to mitigate these risks. These strategies are often generalized actions including patient education; however, targeted interventions (ie, patient education) also improve outcomes by interrogating specific risk factors.

Use of Mixed Reality Technologies by Orthopedic Surgery Residents: A Cross-Sectional Study of Trainee Perceptions

Introduction Recently within surgical education, the development of extended reality (XR) devices has become a topic of interest to improve trainees’ surgical technique outside of the operating room. There is a growing body of literature which supports the use of XR, and it is important to understand the perceptions of orthopedic surgery trainees on the use of XR as an adjunct during training. Purpose Understand the perceptions of orthopedic trainees on the use of XR as an adjunctive surgical training tool. Methods An internally validated 18-question survey was sent to all US orthopedic residency program coordinators with the intent for distribution to each program’s respective residents. Responses with ≥ 70% completion were considered complete. Results Overall, 33% and 18% of residents agreed XR is needed, and all programs should offer XR, respectively. There was overall agreement (67%) for XR’s ability to improve procedural confidence and improve skill progression (65% agreed). Only 25% of respondents felt XR could accurately simulate orthopedic procedures and 36% agreed it could effectively model patient-specific anatomy for preoperative planning. Regarding XR’s ability to reduce intraoperative navigational error, 45% of respondents agreed. However, responses were more neutral for XR’s ability to reduce inpatient length of stay (40%) and ability to improve the accuracy of hardware/prosthetic placement (31%). Finally, 53% of respondents agreed that the largest barrier to integration of XR is cost, while 35% felt that a lack of dedicated time to use the technology during their training program was a major barrier. Conclusion The need for adjunctive surgical training outside of the operating room is clearly demonstrated from our results. Although it is unclear if XR will become a standard tool across all residency programs, orthopedic surgery residents do feel that the technology is useful in terms of skills progression and operative confidence. Thus, this study provides a preliminary framework which suggests a potential role for XR in orthopedic surgery training and the need for further study to address barriers to widespread integration.

Early robotic gait training after stroke (ERA Stroke): study protocol for a randomized clinical trial

BackgroundWalking impairment after stroke is associated with substantial limitations in functional independence, quality of life, and long-term survival. People in the subacute phase after stroke who are unable to walk are most likely to benefit the greatest from use of overground robotic gait training (RGT). This study will provide preliminary evidence regarding the clinical use and efficacy of RGT during the subacute phase of stroke recovery as well as observational findings associated with the safety, tolerability, feasibility, and cost of delivering RGT during inpatient stroke rehabilitation.MethodsThis prospectively registered randomized controlled trial will enroll 54 patients admitted to inpatient rehabilitation within six months of stroke. Admitted patients will be screened at admission to inpatient rehabilitation for eligibility. Consented patients will be randomized based on stroke severity to receive either RGT or usual care for 90 minutes per week of gait training intervention during inpatient rehabilitation length of stay. Patients will complete assessments on walking and health outcomes at admission and discharge from inpatient rehabilitation and at 1- and 3-month follow-up. Intent-to-treat and per protocol analysis will be performed to evaluate safety [rate of adverse events, visual analog scale, and treatment completion rate], walking function [gait speed via 10-Meter Walk Test, Functional Ambulation Category, gait endurance via 6-Minute Walk Test] and health outcomes [Modified Rankin Scale, Stroke Rehabilitation Assessment of Movement, Continuity Assessment Record and Evaluation Tool, 5 Times Sit-to-Stand Test, Berg Balance Scale, and Stroke Impact Scale–16], and cost-analysis.DiscussionThis study will provide foundational evidence regarding the clinical use and efficacy of a RGT program during the subacute phase of stroke recovery with specific findings associated with the safety, tolerability, feasibility, and cost-analysis of delivering RGT during inpatient stroke rehabilitation.Trial registrationNCT06430632.

Determinants of acute psychiatric inpatient length of stay in Ireland.

Ireland has had an historic over-reliance on inpatient mental health care accompanied by poorly resourced community provision. There has been an increasing policy focus on provision of mental health care in the community to facilitate diversion from, or shorten stays in, inpatient care. However, little is known about the determinants of psychiatric inpatient length of stay (LOS) to allow for the targeting of community services. To use a large cross-sectional national dataset to examine the determinants of psychiatric inpatient LOS in the Irish context. Using information on 60,607 discharges from adult acute psychiatric units in Ireland between 2015 and 2019, the study employs both descriptive and regression analysis. Using negative binomial regression models, we control for patient demographic, socioeconomic, and clinical characteristics. In addition, as LOS may be related to provision of non-acute services in the patient area of residence, the analysis also controls for aspects of community service provision. The study finds that longer LOS is associated with older age, being female, and having an involuntary admission. Clinical diagnosis significantly impacts LOS, with diagnoses such as schizophrenia being associated with longer LOS. There is also significant variation in LOS across region of residence, with discharges from some regions staying up to 5days longer. The regional variation observed in inpatient LOS supports the assumption that increased provision of community services diverts or reduces the quantum of care required in inpatient settings. However, without substantive improvement in the community data collected and reported, future planning of mental health services, both community and inpatient, will be substantially curtailed.

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.

Tubeless ureteroenteric anastomosis in robot-assisted radical cystectomy with intracorporeal urinary diversion does not increase the risk of anastomotic stenosis or postoperative complications.

The objective is to demonstrate that omitting ureteral stent placement in robotic intracorporeal urinary diversion does not lead to increased risk of perioperative complications, namely ureteral strictures or anastomotic leaks. We retrospectively reviewed the records of 68 consecutive patients who underwent robotic radical cystectomy with ileal conduit creation or orthotopic neobladder by a single surgeon between January 2020 and September 2023. Chronologically, the first cohort of patients had ureteral stents placed to bridge the ureteroenteric anastomosis, and in the second cohort, stenting was omitted. Cohort 1 consisted of 28 patients with surgeries performed between January 2020 and April 2021, while cohort 2 had 40 patients who underwent surgery from April 2021 to September 2023. The cohorts were well matched with regard to patient age, gender, ASA score and rate of neoadjuvant chemotherapy. The choice of urinary diversion was left to surgeon and patient preference, and there was no significant difference in the proportion of ileal conduits versus orthotopic neobladders within each cohort. Estimated blood loss, total operative time, inpatient length of stay and pathologic T and N staging did not statistically differ between the cohorts. Overall, there was no difference in the rates of postoperative ileus, ureteral stricture, anastomotic leak, infectious complications, and 30-day readmission rates between the groups. Tubeless ureteroenteric anastomosis in patients undergoing robotic radical cystectomy with intracorporeal diversion does not appear to increase the risk of anastomotic strictures or postoperative complications. Further prospective evaluation is warranted.

Emergent endovascular treatment versus medical treatment for acute large vessel occlusions with nondisabling symptoms.

The aim of this study is to analyze the effectiveness and safety of medical treatment (MT) versus endovascular treatment (EVT) in acute large vessel occlusion patients with mild nondisabling stroke symptoms. This study is a multicenter observational study in which data from patients at three stroke centers were prospectively obtained and retrospectively analyzed. Patients were included if they arrived for treatment within 6 h of stroke onset or last known well time and had a baseline National Institutes of Health Stroke Scale (NIHSS) score of ≤5. Primary outcome was modified Rankin Scale (mRS) score 0-2 at 90 days. Secondary outcomes included symptomatic intracranial hemorrhage (sICH), discharge NIHSS score, 90-day all-cause mortality and length of stay. Clinical outcomes were compared through a multivariable logistic regression after adjusting for age, treatment type admission and discharge NIHSS score, admission Alberta Stroke Program Early CT (ASPECT) score and length of stay. Of the 82 patients included in the study, 42 were in the EVT group and 40 were in the MT group. The groups were similar in age (MT:66, EVT:64 age; p = .62), gender (MT:55%, EVT:54.8%; male) admission NIHSS score (MT:2, EVT:3 points; p = .26), ASPECT score (MT:10, EVT:9; p = .15). While discharge NIHSS score was found to be statistically significant between the groups (MT:1, EVT:2; p = .04). There was no difference between the two groups in terms of 90-day mRS scores (MT:1, EVT:1, p = .86) and mortality rates (MT:4, EVT:4; p = .94). In unadjusted analysis, sICH rates were similar between the MT and EVT groups (MT 5%, EVT 7.1%, p = .52). Neurological intensive care unit length of stay (MT:5 days, EVT:2 days p < .001), inpatient clinic length of stay (MT:3, EVT:2 days p = .041), and total length of stay (MT:9 days, EVT:4 days p < .001) were significantly longer in the MT group. Our multicenter study demonstrated that MT with blood pressure augmentation and anticoagulation at hyperacute stage is an alternative option for emergency large vessel occlusion patients with nondisabling mild stroke symptoms.

Association of polypharmacy with clinical outcomes and healthcare utilization in older adults with cardiometabolic diseases: a retrospective cohort study.

Limited knowledge exists on the association between polypharmacy among older patients diagnosed with cardiometabolic diseases and the risk of clinical outcomes and healthcare utilization. This study aimed to estimate the impact of polypharmacy on clinical outcomes and healthcare utilization in older adults with cardiometabolic diseases. A retrospective cohort analysis was performed using data from the Beijing Municipal Medical Insurance Database. The study focused on polypharmacy prescribing patterns in community-dwelling adults 65years and older with cardiometabolic diseases. Polypharmacy was defined as the use of five or more medications on the index date. The primary outcome included clinical outcomes, including hospitalizations and emergency department visits. The secondary outcome focuses on hospital utilization, specifically medication costs and length of stay. The study included a cohort of 405,608 patients. Among these, the most frequently used drug classes in the polypharmacy and non-polypharmacy groups were HMG-CoA reductase inhibitors and dihydropyridines, respectively. After adjustment for covariates, polypharmacy was not associated with an increased risk of hospitalization (odds ratio [OR] 1.09, 95% confidence interval [CI] 0.95-1.26, p = 0.23) or ED visits (OR 1.28, 95% CI 0.97-1.68, p = 0.08). Similarly, no significant association was found with an increase in inpatient medication costs ($2,620.5, 95% CI $2387.3-$2894.3, p = 0.97) or length of stay (3.98days, 95% CI 3.68-4.30days, p = 0.79). However, polypharmacy was associated with higher medication costs in outpatient settings ($73.07, 95% CI $72-$74, p < 0.05) and ED visits ($51.2, 95% CI $44.5-$59.1, p < 0.05). Although polypharmacy is associated with increased healthcare costs in outpatient settings and ED visits, it does not significantly increase the risk of hospitalization or ED visits when properly managed.

Comparison of the epidemiology of elderly trauma between major trauma centres in Riyadh, Saudi Arabia and Melbourne, Australia.

To review the epidemiology of elderly trauma at the Kind Saud Medical City (KSMC), Riyadh, Saudi Arabia, and carry out risk-adjusted analyses to benchmark outcomes with the Alfred Hospital, Melbourne, Australia, the largest Australasian trauma service. This retrospective study included records of injured patients (≥65 years) from the hospital trauma registries during 2022. Demographic and injury data were extracted. Risk-adjusted endpoints were: inpatient mortality and length of stay, analysed using logistic and median regression. A total of 193 elderly patients were registered on the KSMC registry and 1233 elderly patients were registered on the Alfred Hospital registry. Kind Saud Medical City saw proportionally less major trauma (injury severity score of >12, 24.4% vs. 44.2%, p<0.001) and less females (31.1% vs 44.4%, p<0.001). The modal injury group was low level falls in both centres (≈60%). Discharge destination was different, particularly for patients discharged home (86.5% vs. 56%) or to a rehabilitation facility (0.5% vs. 28.2%). The risk-adjusted length of stay was 4.5 days less at the Alfred Hospital (95% CI: [3.25-5.77] days, p<0.001). The odds of in-hospital death were not significantly different (OR=0.72, 95% CI: [0.36-1.47], p=0.37). Despite the different settings, low level falls were the major cause of injury in older patients. A longer length of stay in the acute hospital was identified for KSMC, however, this may be partly explained by discharge destination practices in the 2 countries.

Role of Hospital Connectedness in Brain Metastasis Outcomes

Although patients with brain metastases receive interdisciplinary and multi-institutional care, the association between neuro-oncologic care networks and patient outcomes remains unknown. As patients often interact with multiple facilities, quantifying this association across a network of hospitals is critical to capture the complexity of the health care journey for patients with brain metastases. To evaluate how statewide health care network metrics are associated with inpatient mortality and hospital length of stay (LOS) for patients with brain metastases. This multicenter, statewide cohort study used data from the 2018 to 2019 Healthcare Cost and Utilization Project State Inpatient and Emergency Department Databases. Primary analyses were completed by August 2023. Participants included adults with a brain metastases receiving care in Massachusetts. All inpatient and emergency department visits mapped for patients following the first diagnosis of brain metastasis. Inpatient mortality and hospital LOS were the main outcomes assessed. Hospital interdependence in brain metastases care was calculated using a connectedness score (weighted degree: weighted sum of ties to other care facilities). The association between hospital connectedness and clinical outcomes was analyzed using mixed-effects logistic and linear regression models, adjusting for hospital-level features. In this cohort study, 4679 patients with brain metastases were identified with inpatient or ED encounters in Massachusetts (from 2018 to 2019). The median (IQR) age was 64 (57-73) years, and 2559 (55%) were female. There was interdependence in brain metastases care, with 993 patients (21%) visiting 2 or more unique hospitals. Highly connected hospitals were heterogeneous, with many being small and one-half lacking subspecialty neuro-oncologic care or teaching status. Increased hospital connectedness was significantly associated with improved inpatient mortality for patients with brain metastases, with the lowest connectedness quartile associated with more than double the risk of mortality compared with the highest quartile (odds ratio, 2.34; 95% CI, 1.33-4.11; P = .003). A stepwise increase in inpatient mortality risk was observed as hospital connectedness decreased, independently of hospital volume. Furthermore, intermediate hospital connectedness was associated with increased hospital LOS (coefficient, 1.08; 95% CI, 0.17-1.95; P = .006). This study found that hospital-to-hospital interconnectedness was significantly associated with improved clinical outcomes for patients with brain metastases. The salience of network metrics highlights their potential role alongside other patient-level and hospital-level variables to evaluate and improve oncology care delivery.

Epidemiology and Regional Variation in Additional Surgical Interventions for Children with Congenital Diaphragmatic Hernia: A Multi-institutional Analysis.

To determine practice variation in surgical management of co-morbidities in pediatric patients with Congenital Diaphragmatic Hernia (CDH). A higher percentage of CDH patients are surviving to discharge, accompanied by an increase in morbidity requiring surgical interventions such as tracheostomy and gastrostomy tube insertion. The frequency, trends, and regional variations in operative management of these co-morbidities in this population are unclear. Neonates who underwent CDH repair between 2012-2022 in the United States Pediatric Health Information System database were identified. Multivariable regression identified predictive factors for additional surgical morbidity after CDH repair, defined by an additional surgical intervention during index hospitalization or within one year after discharge. To narrow the spectrum of severity of disease, only patients with an intensive care unit admission on index hospitalization were included. Secondary analysis compared frequency of operations and hospital resource utilization by region. 4003 patients underwent CDH repair and were discharged from their index hospitalization. 1939 (48%) underwent at least one additional surgical procedure after the index CDH repair. Most performed surgeries were gastrostomy tube (28%), fundoplication (13%), and tracheostomy (5%). Covariates associated with additional surgical morbidity included: prematurity (OR 1.38; 95% CI: 1.20-1.59), cardiac co-morbidity (OR 1.31; 95% CI: 1.14-1.49), and chromosomal anomalies (OR 1.76, 95% CI: 1.30-2.40). Northeast (OR: 2.43; CI 1.42-3.52), Midwest (OR 2.11; 95% CI: 1.45-3.07), and South (OR 1.45, 95% CI 1.02-2.12) regions were associated with additional surgical morbidity. Patients who required additional surgical procedures had longer initial inpatient length of stays (71 versus 31d) and higher associated costs ($357,000 versus $161,000). Surgical morbidity exists in CDH patients after initial CDH repair. Counseling families on these outcomes is important in establishing expectations for management. Establishing guidelines for optimal surgical management will require continued reporting from multi-institutional studies.

SP8.1 - Emergency Robotic General Surgery in the UK: Operations, Staff, and Missed Opportunities

Abstract Aims The primary aim was to determine the volume of emergency robotic general surgery performed in the UK. Secondary aims were to determine compatible operations with opportunities for training and the availability of robotic-trained staff. Methods Freedom of Information (FOI) requests were sent to 122 UK Acute Trusts, asking for data on general surgery procedures (open, laparoscopic, robotic) from January 2019 to January 2023. Data on common emergency procedures, in-patient length of stay, robotic complications, and availability of robotically trained staff was requested. Results Of the 122 Acute Trusts, 22 did not respond (82% response rate), 32 had no general surgery robotic access, 16 could not comply due to cost (under section 12 of FOI Act), and 52 provided data. Fifteen Trusts performed emergency robotic surgeries: cholecystectomy (262 cases), hernia repair (140), and appendectomy (3). 86% of these Trusts utilized the DaVinci system, while the CMR Versius system was employed by the remaining 14%. There was a median of 12.5 (range 2-40) robotic-trained staff in-hours, versus a median of 0 (range 0-4) out-of-hours. Conclusions Emergency robotic general surgery in the UK is limited by financial constraints, staff availability, and selective procedural use. Compatible emergency operations that have been performed were cholecystectomies, hernias, and appendectomies. To expand its role, there's a need for training, infrastructure investment, and further research into the cost-effectiveness and outcomes of robotic surgery in emergency cases.

Comparing hospitalized adult patients with chronic anorexia nervosa with versus without prior hospitalizations

BackgroundAnorexia nervosa (AN) is a severe psychiatric disorder, from which recovery is often protracted. The role of prior specialized inpatient treatment on subsequent treatment attempts for adults with chronic AN and predictors of treatment response for severe and enduring AN (SE-AN) are needed to improve outcomes.MethodParticipants (N = 135) with chronic AN (ill ≥7 years) admitted to an integrated inpatient-partial hospitalization eating disorders (ED) unit with prior ED hospitalization(s) (+ PH; n = 100) were compared to those without prior ED hospitalizations (-PH; n = 35) on admission characteristics (BMI, length of illness, outpatient ED treatment history, symptomatology (ED, anxiety, and depressive), history of suicide attempts or non-suicidal self-injury (NSSI)), treatment motivation and recovery self-efficacy, and discharge outcomes (discharge BMI, rate of weight gain, length of stay, clinical improvement).ResultsGroups were similar with regard to age, years ill, and admission BMI. The + PH group had lower desired weight, lifetime nadir BMI and self-efficacy for normative eating, and higher state and trait anxiety than the -PH group. +PH were also more likely to endorse history of NSSI and suicide attempt. Regarding discharge outcomes, most patients achieved weight restoration at program discharge (mean discharge BMI = 19.8 kg/m2). Groups did not differ on rate of weight gain, likelihood of attending partial hospital, partial hospital length of stay, program discharge BMI, or likelihood of clinical improvement (p’s > 0.05) although inpatient length of stay was longer for the + PH group.ConclusionsParticipants with chronic AN + PH exhibited more severe psychiatric comorbidity and lower self-efficacy for normative eating than AN -PH, however short-term discharge outcomes were similar. Future research should determine whether weight restoration and targeting comorbidities impacts relapse risk or need for rehospitalization among chronic and severe + PH. Despite similar illness durations, those with chronic AN -PH may be able to transition to partial hospital earlier. Conversely there is risk of undertreatment of chronic AN + PH given the recent shift promoting briefer self-directed admissions for adults with SE-AN. Research comparing + PH and -PH adults with chronic AN may facilitate efforts to individualize care and characterize relapse risk following intensive treatment.

2283 Early supported discharge for fragility fractures -collaborative working to deliver responsive high quality patient-centred care

Abstract Introduction During 2022, non-femoral fractures that didn’t require operative management had 30 days median inpatient length of stay (LOS) at SBUHB. Femoral fracture patients &amp;gt;65 years had LOS 36 days (GIRFT average 19 days), with 720 admissions. High local incidence is believed to be contributed by historical failures to identify and treat non-femoral fragility fractures. A new service was created from a collective effort to do better for our patients and prevent avoidable harm by breaking down barriers between services and promoting effective collaborative working. Methods A collaboration between the following key services was formed:-. 1. Older Persons Assessment Service (OPAS) -identify fragility fractures presenting to ED 2. Orthogeriatrics -identify suitable femoral fracture patients. 3. Physiotherapy -early assessment and transfer to reablement into the community. 4. Virtual Wards –ongoing CGA and reablement in the community. Additional resource was secured to provide short-term bridging of care and community therapy input. Data was prospectively collected and included demographics, site of fracture, referrer and LOS. Results From March 2023, the service identified 457 patients, 312 (68.7%) Female, median age 86 years. 157 (34.6%) patients had a femoral fracture and 300 (65.4%) were non-femoral fragility fractures, majority identified by OPAS, with 206 (68.7%) being discharged same day. Overall, admission was avoided in 207 (45.3%) patients and 247 (54.6%) had an early discharge/reduced LOS with 3(0.1%) re-admissions avoided. The mean LOS on discharge is 6.6 days with a calculated monthly bed saving of 13.9 days across the service. Conclusion Collaborative working has created an early supported discharge pathway. Femoral fracture patients are discharged earlier, some 3 days post-op, with the necessary support to continue reablement at home. Fragility fractures are identified at the front door and offered same-day discharge with ongoing comprehensive geriatric assessment and reablement within the virtual wards with positive feedback from patients and their families.
