Glycemic Laboratory Values Are Associated With Increased Length of Stay and 90-Day Revision Risk Following Surgical Management of Adult Spinal Deformity

Diabetes mellitus (DM) is a common comorbidity among patients undergoing spinal fusion for adult spinal deformity (ASD) surgery. An elevated Hemoglobin A1c (HbA1c) and elevated postoperative glucose have been shown to increase the risk of complications following spine and other orthopaedic surgeries; however, data is limited for ASD. To investigate glycemic control and ASD surgery to inform surgical decision making, medical optimization, and patient education. Retrospective cohort. Total of 106 adult patients undergoing surgical correction for ASD with an HbA1c drawn within six months preoperatively or two weeks postoperatively and valid plasma glucose levels throughout postoperative hospital stay. Length of stay, 90-day wound complication, 90-day readmission, 90-day revision. All patients undergoing spinal fusion of seven or more levels between 2021 and 2023 at two large academic medical centers were identified using institutional data acquisition software. Medical charts were then manually reviewed to obtain and confirm demographic, laboratory, and surgical characteristics and outcomes. Laboratory characteristics included preoperative HbA1c, mean postoperative glucose (PG), and maximum PG. Surgical characteristics and outcomes included procedure time, estimated blood loss (EBL), length of inpatient stay (LOS), transfusion requirement, 90-day complications, 90-day revision, and 90-day readmission. Bivariate analysis was performed followed by simple and multiple regression analysis. Odds ratios were established relative to the laboratory threshold values informed by receiver operating characteristics. Of 872 original procedures identified, 106 patients (12.2%) were adults with preoperative HbA1c and postoperative plasma glucose measurements who underwent surgery for a diagnosis of ASD. Median patient age was 67 years (IQR 59-72 years), 59 (55.7%) were female, and 96 (90.6%) were of Caucasian race. Median LOS was 7 days (IQR 5-10 years) and median HbA1c was 5.9% (IQR 5.3%-6.5%). Higher preoperative HbA1c was correlated with increased LOS (R=0.22, P=0.023). The odds ratio for patients requiring extended LOS was 2.49 (95% CI 1.06-5.86, P=0.034) for those with HbA1c ≥6.3%. Multiple regression analysis of LOS identified HbA1c [B= 1.51 (95% CI 0.32-2.70), P=0.013] as a positive predictor of LOS and mean PG [B= -0.05 (95% CI -0.10-(-0.01), P=0.019] as a weakly negative predictor of LOS. Upon simple logistic regression, the odds ratio for 90-day revision was 1.81 (95% CI 1.02-3.19, P=0.042) for every unit increase in HbA1c. Patients with mean PG ≥165 mg/dL [OR=5.76 (95% CI 1.28-26.01), P=0.024] were at increased risk for 90-day revision. Glycemic laboratory values do not seem to predict 90-day wound complications or 90-day readmission following surgery for ASD. Elevated preoperative HbA1c is associated with increased LOS and risk for revision within 90 days of ASD surgery. Postoperative hyperglycemia is also associated with increased 90-day revision risk. To our knowledge, this study is the first to evaluate HbA1c and outcomes following ASD surgery. These findings can be leveraged to inform preoperative medical optimization and highlight the importance of glycemic control in ASD patients undergoing corrective surgical intervention.

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.

Time-To-Event Analysis Of Factors Influencing Delay In Discharge From A Subacute Complex Discharge Unit During The Pandemic

Abstract Background Length of stay (LOS) is the most common outcome measure of effectiveness in discharge planning. It refers to the time expressed in days between admission to and discharge from the hospital. During the COVID-19 pandemic, the average inpatient LOS was 5.8 days, representing a slight increase in the average inpatient LOS of 5.7 days between 2016–2019. Tackling delays in patient discharge is an ongoing challenge, and with the emergence of the COVID-19 pandemic, there has been significant disruptions in discharge planning, discontinuity and incoordination between subacute complex discharge units and community care. Methods Our study analysed delaying factors amongst patients with LOS > 15 days during the COVID-19 pandemic using time-to-event analysis. Kaplan–Meier’s plot compared factors causing a delay in discharge to the single factors: age, gender, and multimorbidity. A multivariate Cox regression analysis adjusted to age, gender, and multimorbidity predicted factors affecting LOS. Results A total of 390 patients were admitted between March 2020 – February 2021 to a subacute complex discharge unit in an Irish tertiary centre hospital: 326 (83.6%) were >65 years of age and 233 (59.7%) were female. The median (IQR) age was 79 (70–86) years with a median (IQR) of 19.4 (10–41) days. A total of 237 (60.7%) events were uncensored, with LOS > 15 days, of which 138 (58.2%) were female and 124 (52.32%) had > 4 comorbidities; 153 (39.2%) were censored into LOS ≤ 15 days, and death occurred in 19 (4.8%). Conclusion Our study is the first to analyse common factors delaying discharge from a complex discharge unit. Further research is required to explore multimorbidity as a risk factor for mortality in patients with prolonged LOS within a complex discharge unit and target gender-specific frailty measures to achieve high-quality patient management.

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.

Does Discharge Disposition or Length of Stay for Patients Undergoing Staged Bilateral Total Joint Arthroplasty Change Between First and Second Procedures?

Introduction This study investigates whether ambulatory surgery rates, discharge disposition, or hospital length of stay (LOS) differ between the first and second surgeries for staged bilateral total joint arthroplasty (TJA). We hypothesize that patients have higher rates of ambulatory surgery and shorter LOS for the second surgery. Methods Data were retrospectively collected from staged bilateral total knee (TKA) or total hip arthroplasty (THA) patients within a 12-month period. Ambulatory surgery rates, discharge to home, and LOS after first (LOS_1) vs. second surgery (LOS_2) were compared. Multivariable regression analysis was performed to identify predictors of shorter LOS. Results Rates of ambulatory surgery were significantly higher after second surgery for TKA (28.7% vs. 20.2%, p<0.001) but not for THA (24.8% vs. 23.0%, p=0.405). Likelihood of discharge to home was not significantly different between first and second surgeries for TKA (p=0.225) or THA (p=0.248). LOS_2 was significantly shorter than LOS_1 for TKA (1.4 vs 1.6 days, p=0.005) but not for THA (1.4 vs 1.4 days, p=0.723). Undergoing TKA (OR=1.846, 95% CI=[1.142, 2.984]), former smoking (OR=1.686, 95% CI=[1.068, 2.660]), and younger age (OR=0.968, 95% CI=[0.939, 0.997]) were associated with LOS_2<LOS_1. Conclusions Our results show higher rates of ambulatory surgery and shorter LOS after second surgery vs. first for staged bilateral TKA but not THA. Factors associated with LOS_2<LOS_1 include undergoing TKA, former smoking, and younger age.

Factors Associated With Unplanned Readmissions and Prolonged Length of Stay in Patients Undergoing Primary Fusion for Congenital Scoliosis.

Approximately 50% of patients with congenital scoliosis will require surgical treatment to prevent further progression. Outcomes following congenital scoliosis are sparse in the literature. The purpose of this study was to identify independent risk factors associated with unplanned readmission and prolonged length of stay (LOS) in patients undergoing primary surgical treatment for congenital scoliosis. The National Surgical Quality Improvement Database-Pediatric was queried for database years 2016-2018 to identify patients with congenital scoliosis who underwent primary posterior fusion of the spine. Patient demographics, comorbidities, and operative variables, such as the number of levels fused and the American Society of Anesthesiologists (ASA) classificaiton, were collected. Univariate and multivariate analyses of patient factors were performed to test for association with readmission within 30 days and prolonged LOS (>4 days). Eight hundred sixteen patients were identified. The average age was 11.3 ± 4.02 years, and the mean postoperative LOS was 4.64 ± 3.71 days. Forty-three patients (5.40%) were readmitted, and 73 patients (8.96%) had prolonged LOS. Independent risk factors associated with prolonged LOS included chronic lung disease (P < 0.001), presence of a tracheostomy (P < 0.001), structural central nervous system abnormality (P = 0.039), oxygen support (P < 0.001), and number of levels fused (P = 0.008). The factors independently associated with unplanned readmission were fusion to the pelvis (P = 0.004) and LOS >4 days (P = 0.008). Prolonged LOS and readmission are widely being used as quality and performance metrics for hospitals. Congenital scoliosis, which often progresses rapidly resulting in significant deformity, frequently requires surgery at an earlier age than idiopathic and neuromuscular deformity. Nevertheless, 30-day outcomes for surgical intervention have not been thoroughly studied. The present study identifies risk factors for prolonged LOS and readmission, which can facilitate preoperative planning, patient/family counseling, and postoperative care. Congenital scoliosis management poses certain challenges that may be mitigated by understanding the risk factors for adverse outcomes following primary fusion surgery.

Long-term trends in incidence and outcomes of rib fractures: A population-based data linkage study from New South Wales, Australia.

Determine long-term trends in population-based incidence and outcomes of rib fracture hospitalisations. This was a data linkage study of rib fracture cases identified between 2015 and 2022 in New South Wales, Australia. Routinely collected health data were linked between ED, admitted patient and death registry data collection. The primary outcomes were age-specific incidence of rib fracture hospitalisation cases and risk-adjusted 30 days mortality. Other outcomes of interest were hospital length of stay (LOS), admission rate and ICU admissions. A total of 70 609 cases were analysed. Overall, the number of rib fracture hospitalisations increased by 25% between 2015 and 2022. The highest proportion of cases was in the 45-65 years (28%) and 65-85 years (31%) age groups. On a per population basis, the incidence rate increased by 2% per annum. After adjusting for age, comorbidity and injury severity, there was no significant trend in 30 days mortality observed between 2015 and 2022. The median inpatient LOS was 4 days with 38% of patients staying 1-2 days. Regional and rural areas were associated with more severe chest injuries. Rib fracture hospitalisations have increased with older patients driving this trend.

The Association Between Early Initiation of Systemic Corticosteroids and the Hospital Length of Stay in Patients With Multisystem Inflammatory Syndrome in Children.

Patients with multisystem inflammatory syndrome in children (MIS-C) often require hospital admission. Treatment of MIS-C has included intravenous immunoglobulin, systemic corticosteroids, and/or immunomodulators. There is no standardized approach to when steroids should be initiated during treatment. The study objective was to determine whether early initiation of steroids in patients with MIS-C is associated with the duration of hospital length of stay (LOS). This is a single-center retrospective cohort study of patients younger than 21 years who were hospitalized with MIS-C between March 2020 and September 2021 and received steroids. Cases were obtained from an institutional MIS-C log. Patients with culture proven sepsis and/or those who received intravenous immunoglobulin or steroids within the previous 30 days were excluded. We used a multivariable linear regression model, controlling for potential confounders, to assess the association between early steroids and LOS. A total of 56 patients hospitalized with MIS-C were identified; 38 received systemic corticosteroids and were included in the study. The mean time from admission to steroid administration was 9.8 hours (SD = 7.7) in the early group and 44.6 hours (SD = 14.2) in the late group. There was a statistically significant difference in baseline characteristics of patients receiving early versus late steroids in initial C-reactive peptide, procalcitonin, brain natriuretic peptide, and cardiac dysfunction. After controlling for confounders, initiating steroids within 24 hours of admission for MIS-C was associated with a decreased hospital LOS: in patients treated with early steroids, LOS was 58.3 hours less (95% confidence interval, -100.0 to -16.6; P = 0.007) than in those who received late steroids. Among patients with MIS-C, initiating systemic corticosteroids within 24 hours of admission was associated with decreased hospital LOS.

Factors Associated with Do Not Resuscitate Status and Palliative Care in Hospitalized Patients: A National Inpatient Sample Analysis.

Patients from diverse sociocultural backgrounds and with differing medical conditions may have varying levels of acceptance of advanced care planning and palliative care. We performed a retrospective analysis of the National Inpatient Sample for patients discharged from January 1, 2016, to December 31, 2019, with conditions associated with frequently terminal conditions. We recorded demographic variables, do not resuscitate (DNR) status, and palliative care (PC) status and analyzed the associations between outcomes, mortality, and length of stay (LOS). A total of 23,402,637 patient records were included in the study, of which 2% were DNR and PC, 5% were DNR only, and 1% was PC only. From 2016 to 2019, the percentage of patients with PC increased from 2.55% to 3.27% and DNR from 6.31% to 7.7%. Black patients were less likely to have DNR status (odds ratio [OR] 0.72 [0.71-0.72]) but had similar PC rates. Male patients were less likely to have a DNR order in place (OR 0.89 [0.89-0.89]) but more likely to be in PC (OR 1.05 [1.04-1.05]). The diagnoses with the highest association with DNR status were lung cancer (OR 4.1 [4.0-4.5]), pancreatic cancer (OR 4.6 [4.5-4.7]), and sepsis (OR 2.9 [2.9-2.9]) The diagnoses most associated with PC were lung cancer (OR 6.3 [6.2-6.4]), pancreatic cancer (OR 8.1 [7.1-8.3]), colon cancer (OR 4.9 [4.8-5.1]), and senile brain degeneration of the brain OR 6.5 [5.3-7.9]). Mortality and LOS decreased between 2016 and 2019, but hospital charges increased (p < 0.001). Black race and male gender were associated with higher inpatient mortality (OR 1.12 [1.12-1.14]), LOS, and hospital charges. In the United States, the proportion of hospitalized patients with DNR, PC, and DNR with PC increased from 2016 to 2019. Overall, inpatient mortality and LOS fell, but hospital charges per patient increased. Significant gender and ethnic differences emerged. Black patients and males were less likely to have DNR status and had higher inpatient mortality, LOS, and hospital charges.

Association between physician-hospital integration and inpatient care delivery in accountable care organizations: An instrumental variable analysis.

To investigate the relationship between physician-hospital integration within accountable care organizations (ACOs) and inpatient care utilization and expenditure. The primary data were Massachusetts All-Payer Claims Database (2009-2013). Fifteen provider organizations that entered a commercial ACO contract with a major private payer in Massachusetts between 2009 and 2013. Using an instrumental variable approach, the study compared inpatient care delivery between patients of ACOs demonstrating high versus low integration. We measured physician-hospital integration within ACOs by the proportion of primary care physicians in an ACO who billed for outpatient services with a place-of-service code indicating employment or practice ownership by a hospital. The study sample comprised non-elderly adults who had continuous insurance coverage and were attributed to one of the 15 ACOs. Outcomes of interest included total medical expenditure during an episode of inpatient care, length of stay (LOS) of the index hospitalization, and 30-day readmission. An inpatient episode was defined as 30, 45, and 60 days from the admission date. Not applicable. The study examined 33,535 admissions from patients served by the 15 ACOs. Average medical expenditure within 30 days of admission was $24,601, within 45 days was $26,447, and within 60 days was $28,043. Average LOS was 3.5 days, and 5.4% of patients were readmitted within 30 days. Physician-hospital integration was associated with a 10.6% reduction in 30-day expenditure (95% CI, -15.1% to -5.9%). Corresponding estimates for 45 and 60 days were - 9.7% (95%CI, -14.2% to -4.9%) and - 9.6% (95%CI, -14.3% to -4.7%). Integration was associated with a 15.7% decrease in LOS (95%CI, -22.6% to -8.2%) but unrelated to 30-day readmission rate. Our instrumental variable analysis shows physician-hospital integration with ACOs was associated with reduced inpatient spending and LOS, with no evidence of elevated readmission rates.

Examining Factors Influencing Length of Stay for Inpatients at Alcohol and Substance Addiction Treatment Center

Objective: The aim of this study is to determine the impact of impulsivity, treatment motivation, anxiety, and cognitive distortions on the duration of inpatient treatment for substance use.&#x0D; Methods: The sample for the study consisted of 200 volunteer patients receiving inpatient treatment at the Alcohol and Substance Addiction Treatment Center. Participants underwent a general psychopathological evaluation using the Structured Clinical Interview for DSM-5 (SCID-5) administered by the clinician. All participants were given the Case Report Form prepared by the clinician along with the Barratt Impulsivity Scale-11 Short Form (BIS), Automatic Thoughts Scale (ATS), State and Trait Anxiety Inventory (STAI-I, STAI-II) and Treatment Motivation Questionnaire (TMQ).&#x0D; Results: A significant distinction was noted in discharge statuses when comparing scores on the Barratt Impulsiveness Scale and nonplaning impulsiveness subscale, and the State and Trait Anxiety Inventory and Automatic Thoughts Scale. Those who were discharged with remission had notably lower scores compared to those who left voluntarily or were discharged due to rule violation (p&lt; 0.001). Negative significant correlations were found between length of stay and Barratt Impulsiveness Scale and its subscales [BIS-T (p

Circumferential resection margin rates in esophageal cancer resection- oncological equivalency and comparable clinical outcomes between open versus minimally invasive techniques: A retrospective cohort study.

Radical surgery for esophageal cancer requires macroscopic and microscopic clearance of all malignant tissue. A critical element of the procedure is achieving a negative circumferential margin (CRM) to minimize local recurrence. The utility of minimally invasive surgery poses challenges in replicating techniques developed in open surgery, particularly for hiatal dissection in esophago-gastrectomy. In this study, the technical approach and clinical and oncological outcomes for open and laparoscopic esophago-gastrectomy are described with particular reference to CRM involvement. This cohort study included all patients undergoing either open or laparoscopic esophago-gastrectomy between January 2004 to June 2022 in a single tertiary center. A standard surgical technique for hiatal dissection of the esophago-gastric junction developed in open surgery was adapted for a laparoscopic approach. Clinical parameters, length of stay (LOS), post-operative complications and mortality data were collected and analyzed by a Mann-Whitney U or Fisher's exact method. Overall 447 patients underwent an esophago-gastrectomy in the study with 219 open and 228 laparoscopic procedures. The CRM involvement was 18.8% in open surgery and 13.6% in laparoscopic surgery. The 90-day-mortality for open surgery was 4.1% compared with 2.2% for laparoscopic procedures. Median Intensive care unit (ITU), inpatient LOS and 30-day readmission rates were shorter for laparoscopic compared with open esophago-gastrectomy (ITU: 5 versus 8 days, P=0.0004; LOS: 14 versus 20 days, P=0.022; 30-day re-admission 7.46% versus 10.50%). Post-operative complication rates were comparable across both cohorts. The rates of starting adjuvant chemotherapy were 51.8% after open and 74.4% in laparoscopic esophago-gastrectomy. This study presents a standardized surgical approach to hiatal dissection for esophageal cancer. We present equivalence between open and laparoscopic esophago-gastrectomy in clinical, oncological and survival outcomes with similar rates of CRM involvement. We also observe a significantly shorter hospital length of stay with the minimally invasive approach.

Single Intravenous Dose Dalbavancin Pathway for the Treatment of Acute Bacterial Skin and Skin Structure Infections: Considerations for Emergency Department Implementation and Cost Savings

BackgroundA pathway for the treatment of acute bacterial skin and skin structure infections (ABSSSI) with a single intravenous (IV) dose of dalbavancin was previously shown to reduce hospital admissions and shorten inpatient length of stay (LOS). ObjectivesTo describe pathway implementation at the emergency department (ED) and evaluate cost-effectiveness of a single-dose dalbavancin administered to ED patients who would otherwise be hospitalized to receive usual care with multidose IV antibiotics. MethodsThe dalbavancin pathway was previously implemented at 11 U.S. EDs (doi:10.1111/acem.14258). Patients with ABSSSI, without an unstable comorbidity or infection complication requiring complex management, were treated with a single dose of dalbavancin. At the emergency physicians’ discretion, patients were either discharged and received outpatient follow-up or were hospitalized for continued management. A decision analytic cost-effectiveness model was developed from the U.S. healthcare's perspective to evaluate costs associated with the dalbavancin pathway compared with inpatient usual care. Costs (2021 USD) were modeled over a 14-day horizon and included ED visits, drug costs, inpatient stay, and physician visits. One-way and probabilistic sensitivity analyses examined input parameter uncertainty. ResultsDriven largely by the per diem inpatient cost and LOS for usual care, the dalbavancin pathway was associated with savings of $5133.20 per patient and $1211.57 per hospitalization day avoided, compared with inpatient usual care. The results remained robust in sensitivity and scenario analyses. ConclusionThe new single-dose dalbavancin ED pathway for ABSSSI treatment, which was previously implemented at 11 U.S. EDs, offers robust cost savings compared to inpatient usual care.

Postoperative Length of Stay in Patients With Stress Hyperglycemia Compared to Patients With Diabetic Hyperglycemia: A Retrospective Cohort Study.

Postoperative hospital length of stay (LOS) is longer in patients with diabetes than in patients without diabetes. Stress hyperglycemia (SH) in patients without a history of diabetes has been associated with adverse postoperative outcomes. The effect of SH on postoperative LOS is uncertain. The aim of this study is to compare postoperative LOS in patients with SH to patients with diabetic hyperglycemia (DH) following noncardiac surgery. We carried out a retrospective cohort study of inpatients with at least two glucose measurements ≥180 mg/dL. Two groups were compared. Patients with SH had no preoperative history of diabetes. Patients were considered to have DH if they had an established preoperative diagnosis of diabetes mellitus or a preoperative hemoglobin A1c (HbA1c) ≥6.5%. The primary outcome measure was hospital LOS. We included 270 patients with postoperative hyperglycemia-82 in the SH group and 188 in the DH group. In a linear regression analysis, hospital LOS was longer in the SH group than in the DH group (10.4 vs 7.3 days; P = .03). Within the SH group, we found no association between LOS and prompt treatment of hyperglycemia within 12 hours (P = .43), insulin dose per day (P = .89), or overall mean glucose (P = .13). Postoperative LOS was even longer in patients with SH than in patients with DH, representing a potential target for quality improvement efforts. We did not, however, find evidence that improved treatment of SH was associated with reduction in LOS.

P/F Ratio is a Better Predictor for Non-Invasive Ventilation Failure and Length of Stay in Patients with Community-Acquired Pneumonia

Introduction: Community-acquired pneumonia (CAP) can deteriorate into respiratory failure requiring immediate ventilatory intervention. This study compared the performance of the PaO2/FiO2 (P/F) ratio, the ratio of oxygen saturation (ROX) index, and the heart rate, acidosis, consciousness, oxygenation, and respiratory rate (HACOR) score in predicting non-invasive ventilation (NIV) failure and length of hospital stay in patients diagnosed with CAP. Methods: This study was conducted at Universitas Sebelas Maret Hospital, Surakarta, from March to September 2023. All patients diagnosed with CAP who were eligible for NIV were recruited. Each patient’s age, sex, comorbidities, vital signs, pneumonia severity index (PSI), blood urea, bilirubin, hematocrit, blood sodium, P/F ratio, ROX index, and HACOR score were measured within the first 24 hours of NIV. Subsequently, the correlations between these variables and NIV failure (intubation or mortality) and length of hospital stay were assessed. Results: The P/F ratio, ROX index, and HACOR score were not correlated with intubation or length of stay. The P/F ratio was correlated with mortality (p = 0.040), whereas the other scores were not. Higher body temperature was correlated with intubation (p = 0.032). PSI was correlated with both mortality (p = 0.033) and length of hospital stay (p = 0.009). Conclusion: The P/F ratio is superior to the ROX index and HACOR score in predicting mortality in patients with pneumonia-related respiratory failure treated with NIV. Since it is simple and accessible, measuring the P/F ratio within the first 24 hours of NIV is recommended to identify a patient’s risk of NIV failure and apply appropriate monitoring.

Hospitalization, case fatality, comorbidities, and isolated pathogens of adult inpatients with pneumonia from 2013 to 2022: a real-world study in Guangzhou, China

BackgroundIn the context of increasing population aging, ongoing drug-resistant pathogens and the COVID-19 epidemic, the changes in the epidemiological and clinical characteristics of patients with pneumonia remain unclear. This study aimed to assess the trends in hospitalization, case fatality, comorbidities, and isolated pathogens of pneumonia-related adult inpatients in Guangzhou during the last decade.MethodsWe retrospectively enrolled hospitalized adults who had doctor-diagnosed pneumonia in the First Affiliated Hospital of Guangzhou Medical University from January 1, 2013 to December 31, 2022. A natural language processing system was applied to automatically extract the clinical data from electronic health records. We evaluated the proportion of pneumonia-related hospitalizations in total hospitalizations, pneumonia-related in-hospital case fatality, comorbidities, and species of isolated pathogens during the last decade. Binary logistic regression analysis was used to assess predictors for patients with prolonged length of stay (LOS).ResultsA total of 38,870 cases were finally included in this study, with 70% males, median age of 64 (53, 73) years and median LOS of 7.9 (5.1, 12.8) days. Although the number of pneumonia-related hospitalizations showed an upward trend, the proportion of pneumonia-related hospitalizations decreased from 199.6 per 1000 inpatients in 2013 to 123.4 per 1000 in 2021, and the case fatality decreased from 50.2 per 1000 in 2013 to 23.9 per 1000 in 2022 (all P < 0.05). The most common comorbidities were chronic obstructive pulmonary disease, lung malignancy, cardiovascular diseases and diabetes. The most common pathogens were Pseudomonas aeruginosa, Candida albicans, Acinetobacter baumannii, Stenotrophomonas maltophilia, Klebsiella pneumoniae, and Staphylococcus aureus. Glucocorticoid use during hospitalization (Odd Ratio [OR] = 1.86, 95% Confidence Interval (CI): 1.14–3.06), immunosuppressant use during hospitalization (OR = 1.99, 1.14–3.46), ICU admission (OR = 16.23, 95%CI: 11.25–23.83), receiving mechanical ventilation (OR = 3.58, 95%CI: 2.60–4.97), presence of other underlying diseases (OR = 1.54, 95%CI: 1.15–2.06), and elevated procalcitonin (OR = 1.61, 95%CI: 1.19–2.19) were identified as independent predictors for prolonged LOS.ConclusionThe proportion of pneumonia-related hospitalizations and the in-hospital case fatality showed downward trends during the last decade. Pneumonia inpatients were often complicated by chronic underlying diseases and isolated with gram-negative bacteria. ICU admission was a significant predictor for prolonged LOS in pneumonia inpatients.

Prediction of 30-day and 1-year postoperative complications after balloon-assisted kyphoplasty in the elderly using the Risk Analysis Index.

Vertebral compression fracture (VCF) is the most prevalent fragility fracture. When conservative management fails, patients may undergo balloon-assisted kyphoplasty (BAK). In BAK, an expandable balloon preforms a cavity in the fractured vertebra before injection of bone cement. The aim of this study was to compare outcomes in patients stratified by age and frailty assessed by the Risk Analysis Index (RAI). A retrospective analysis of 334 BAK procedures (280 patients) for osteoporotic VCFs at a single institution was performed (2015-2022). Patients with at least 1 year of follow-up were eligible for inclusion. Patient demographics were recorded, including age, sex, BMI, RAI score, tobacco and steroid use, osteoporosis treatments, and bone density. Patients who underwent outpatient surgery were identified, and length of stay (LOS) was obtained for admitted patients. The rates of additional VCFs after kyphoplasty, 30-day and 1-year postoperative complications, and reoperation were identified. The overall rates of additional VCFs, 30-day postoperative complications, 1-year postoperative complications, and reoperation were 16.2%, 5.1%, 12.0%, and 6.3%, respectively. Patients were stratified by age: nonelderly (< 80 years; 220 patients, 263 treated vertebrae) and elderly (≥ 80 years; 60 patients, 71 treated vertebrae). There were no differences in sex (p = 0.593), tobacco use (p = 0.973), chronic steroid use (p = 0.794), treatment for osteoporosis (p = 0.537), bone density (p = 0.056), outpatient procedure (p = 0.273), and inpatient LOS (p = 0.661) between both groups. There were also no differences in the development of additional VCFs (p = 0.862) at an adjacent level (p = 0.739) or remote level (p = 0.814), 30-day and 1-year postoperative complications (p = 0.794 and p = 0.560, respectively), and reoperation rates (p = 0.420). Patients were then analyzed by RAI: nonfrail (RAI score < 30; 203 patients, 243 treated vertebrae) and frail (RAI score ≥ 31; 77 patients, 91 treated vertebrae). There were no differences in tobacco use (p = 0.959), chronic steroid use (p = 0.658), treatment for osteoporosis (p = 0.560), bone density (p = 0.339), outpatient procedure (p = 0.241), inpatient LOS (p = 0.570), and development of additional VCFs (p = 0.773) at an adjacent level (p = 0.390) or remote level (p = 0.689). However, rates of 30-day and 1-year postoperative complications in frail patients more than doubled in comparison with nonfrail patients (p = 0.031 and p = 0.007, respectively), and frail patients trended toward reoperation (p = 0.097). BAK is a safe treatment in the elderly, and age alone should not be used as an exclusion criterion during patient selection. Frailty, which can be assessed reliably using the RAI, may serve as a better predictor for postoperative complications and reoperation following BAK.

Impact on Inpatient Length of Stay in Adults with Deep Partial-Thickness Burns: Comparing the Bioengineered Allogeneic Cellularized Construct Expanded-Access Trial with National Burn Repository Data.

To investigate the effect of StrataGraft (bioengineered allogeneic cellularized construct [BACC]) treatment on inpatient length of stay (LOS) as an indicator of hospital resource utilization. Data from the single-arm StrataCAT trial for adult patients with deep partial-thickness (DPT) burns who received BACC were compared with data from a matched external control arm comprising patients who received autografting for burn treatment from the National Burn Repository (NBR) during the same time period as StrataCAT. A matching, quasi-experimental approach was used to investigate the cause-and-effect relationship between BACC treatment and LOS (days). Matching factors included sex, age, ethnicity, race, burn causes, %TBSA burned (third-degree), %TBSA burned (second- and third-degrees), inhalation injury, diabetes mellitus, and hypertension. Balance was assessed between the cohorts for each confounder by standardized mean differences (SMD). Outcome was reported as average treatment effect on the treated. The BACC and NBR Autograft cohorts included 47 and 2641 patients, respectively. Following matching, the Autograft cohort had 137 patients and was weighted to 47 patients. Patients in the BACC and final (matched) Autograft cohorts were similar in all demographic and clinical covariate categories after matching (ie, the absolute SMD were < 0.1). Treatment with BACC reduced the inpatient LOS by an average of 4.84 days (P = 0.0127) relative to the comparable (matched) Autograft cohort. An ad hoc analysis revealed that mean [SD] LOS for BACC and the weighted Autograft cohorts were 17.68 [12.75] and 22.51 [19.75] days, respectively, and were 1.39 [0.94] and 1.88 [1.31] days per %TBSA burned, respectively. The significantly reduced inpatient LOS observed with BACC compared to Autograft in adults with DPT burns may translate into reduced burden on the healthcare system, reduced costs for inpatient burn treatment, and clinical benefits for patients.

Factors Affecting Length of Stay in Patients With Traumatic Rib Fractures in a District General Hospital.

Abstract Objective The objective of this study was to ascertain which patient factors, injury and treatment variables contributed to an increased length of stay (LOS). Methods Retrospective data collection from a prospectively updated dataset was conducted from 01.01.23 to 31.08.23. All adult patients admitted to the general surgical department were included. Transfers directly from ED to an MTC, and paediatric patients were excluded. Outcome parameters were: age, gender, clinical frailty score (CFS), preinjury antiplatelet/anticoagulant use, mechanism of injury, number of ribs fractured, battle score, presence of intrathoracic injury, presence of flail chest, chest drain insertion, performance of analgesic nerve block, discussion with local MTC, total LOS, and 30-day mortality. Statistical analysis was performed to ascertain which of these variables significantly affected patient LOS. Results 92 patients were admitted to the DGH. Most were female (58.7%) and the median age was 73. Median LOS was 5.5 days. 7 patients died during admission, all with a CFS of 6 or over. Patients with a higher age, CFS, number of fractures, and battle score had a significantly longer LOS. Patients who underwent a nerve block also had a longer LOS than those who did not. Presence of intra-thoracic injury and placement of a surgical chest drain did not affect LOS. Conclusions LOS appears to be related to higher age, frailty, and battle score. To improve patient management at this DGH, it may be suggested that older patients with a high battle score be discussed with critical care and have early frailty team input.

Assessing the Impact of the Covid-19 Pandemic on Outcomes of Patient Admitted with Sickle Cell Disease

Introduction: Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy which affects millions of people worldwide. It is caused by a substitution of the glutamic acid (Glu) amino acid with valine (Val) at the sixth position of the β-globin gene, resulting in a mutated hemoglobin tetramer, HbS, in the erythrocytes of affected individuals. This morphology results in sickle-shaped red blood cells and hemolysis when deoxygenated and leads to vaso-occlusion with associated ischemia. SCD is characterized by repeated severe acute pain episodes, acute chest syndrome, and can be complicated by stroke, nephropathy, avascular necrosis, and more. Many studies have shown disparities in outcomes in racial/ethnic minorities as well as in those with lower socioeconomic status. These factors have also been linked to increased risk of COVID-19 infection and infection related mortality. In this study, we aim to explore the baseline characteristics of patients with SCD, prevalence of hospitalizations, and compare inpatient outcomes during the COVID-19 pandemic with those prior to the pandemic. Methods: Nationwide Inpatient Sample (NIS) was queried to determine adult hospitalized patients with a primary diagnosis of SCD using ICD-10 codes. They were stratified into two cohort groups based on year of admission, comparing admissions during 2016-2019 with admission during the year 2020. Primary outcomes assessed were inpatient mortality, length of stay (LOS), and total hospitalization charges. Secondary outcomes included respiratory failure, need for mechanical ventilation, cerebrovascular accident (CVA), myocardial infarction (MI), acute kidney injury (AKI), pulmonary embolism (PE), and need for blood transfusions. Multivariate linear and logistic regression analysis was performed to adjust for confounding variables. Results: A total of 456, 750 patients were hospitalized with SCD. 377, 285 were admitted between 2016-2019 and 79, 465 were admitted during 2020. Age distribution and sex were similar between the two groups. Patients admitted in the year 2020 were older and had more comorbidities when compared to patients admitted during prior years. Distribution of race, insurance type, hospital type, hospital size, hospital locations, and household income was not significantly different between the two groups. In 2020 patients admitted with SCD had greater odds of developing acute respiratory failure and PE, though the overall prevalence of these secondary outcomes were very low (3.6% and 0.80% respectively). Despite these outcomes, there was no significant difference in inpatient mortality (0.31% vs. 0.23%) for SCD patients admitted during 2020 when compared to prior years. In addition, the length of hospital stay was not significantly different in these two groups as well (5.1 vs. 4.9 days). Finally, patients admitted in 2020 incurred significantly higher hospital costs than SCD during pre-pandemic years ($42, 307 vs. $36, 087). Conclusion: SCD is the most common hemoglobinopathy in the United States. The African American population is most commonly affected by this disease. In addition, it is well known that this racial minority suffers inequities in accessing and receiving health care, which is associated with worse overall outcomes. During the COVID-19 pandemic, reduced access to hospital services combined with fear of exposure to the virus, led to a significant drop in overall access to healthcare and treatment. In this study, we found that those with SCD admitted during the COVID-19 pandemic overall had more comorbidities and more commonly had respiratory failure and pulmonary embolism, yet there was no change in inpatient mortality and LOS for these patients. Although disparities existed during the pandemic, it is fortunate that SCD itself did not serve as an additional risk factor for inpatient mortality and hospitalization duration.
