ABSTRACT

OBJECTIVE: To examine the association between being born into relative deprivation and hospital costs during childhood.

DESIGN: Retrospective cohort study.

METHODS: We created a birth cohort using Hospital Episode Statistics for children born in NHS hospitals in 2003/2004. The Index of Multiple Deprivation (IMD) rank at birth was missing from 75% of the baby records, so we linked mother and baby records to obtain the IMD decile from the mother’s record. We aggregated and costed each child’s hospital inpatient admissions, and outpatient and emergency department (ED) attendances up to 15 years of age. We used 2019/2020 NHS tariffs to assign costs. We constructed an additional cohort, all children born in 2013/2014, to explore any changes over time, comparing the utilisation and costs up to 5 years of age.

RESULTS: Our main cohort comprised 567 347 babies born in 2003/2004, of which we could include 91%. Up to the age of 15 years, children born into the most deprived areas used more hospital services than those born in the least deprived, reflected in higher costs of inpatient, outpatient and ED care. The highest costs and greatest differences are in the year following birth. Comparing this with the later cohort (up to age 5 years), the average cost per child increased across all deprivation deciles, but differences between the most and least deprived deciles appeared to narrow slightly.

CONCLUSIONS: Healthcare utilisation and costs are consistently higher for children who are born into the most deprived areas compared with the least.

ABSTRACT

BACKGROUND: Little is known about the procedural characteristics, case volumes, and mortality rates for early- vs non-early-career interventional cardiologists in the United States.

OBJECTIVES: This study examined operator-level data for patients who underwent percutaneous coronary intervention (PCI) between April 2018 and June 2022.

METHODS: Data were collected from the National Cardiovascular Data Registry CathPCI Registry, American Board of Internal Medicine certification database, and National Plan and Provider Enumeration System database. Early-career operators were within 5 years of the end of training. Annual case volume, expected mortality and bleeding risk, and observed/predicted mortality and bleeding outcomes were evaluated.

RESULTS: A total of 1,451 operators were early career; 1,011 changed their career status during the study; and 6,251 were non-early career. Overall, 514,540 patients were treated by early-career and 2,296,576 patients by non-early-career operators. The median annual case volume per operator was 59 (Q1-Q3: 31-97) for early-career and 57 (Q1-Q3: 28-100) for non-early-career operators. Early-career operators were more likely to treat patients presenting with ST-segment elevation myocardial infarction and urgent indications for PCI (both P < 0.001). The median predicted mortality risk was 2.0% (Q1-Q3: 1.5%-2.7%) for early-career and 1.8% (Q1-Q3: 1.2%-2.4%) for non-early-career operators. The median predicted bleeding risk was 4.9% (Q1-Q3: 4.2%-5.7%) for early-career and 4.4% (Q1-Q3: 3.7%-5.3%) for non-early-career operators. After adjustment, an increased risk of mortality (OR: 1.08; 95% CI: 1.05-1.17; P < 0.0001) and bleeding (OR: 1.08; 95% CI: 1.05-1.12; P < 0.0001) were associated with early-career status.

CONCLUSIONS: Early-career operators are caring for patients with more acute presentations and higher predicted risk of mortality and bleeding compared with more experienced colleagues, with modestly worse outcomes. These data should inform institutional practices to support the development of early-career proceduralists.

ABSTRACT

BACKGROUND: Periprosthetic joint infection (PJI) after total knee arthroplasty (TKA) is a devastating complication. Intrawound vancomycin powder has been shown to reduce infection rates in spine surgery, but its role in arthroplasty remains controversial. This prospective randomized control trial aimed to evaluate the efficacy of intrawound vancomycin in preventing PJI after primary TKA.

METHODS: A total of 1,022 patients were randomized to the study group (n = 507, who received 2 grams intrawound vancomycin powder before arthrotomy closure) or to the control group (n = 515, no local vancomycin) with a minimum follow-up of 12-months. The primary outcome was the incidence of PJI or surgical site infection (SSI). Secondary outcomes included associated minor complications such as stitch abscess, persistent wound drainage, and delayed stitch removal. Other parameters evaluated include reoperation rates and incidences of nephrotoxicity.

RESULTS: The overall infection rate in 1,022 patients was 0.66%. There was no significant difference in PJI rate in the study group (N = 1; 0.2%) versus the control group (N = 3; 0.58%), P = .264. Reoperation rates in the study group (N = 4; 0.78%) and control (N = 5; 0.97%), and SSI rates in the study (N = 1; 0.2%) and control groups (N = 2; 0.38%) were comparable. The Vancomycin cohort, however, demonstrated a significantly higher number of minor wound complications (n = 67; 13.2%) compared to the control group (n = 39; 7.56%, P < .05). Subgroup analysis showed diabetics in the study group to also have a higher incidence of minor wound complications (24 [14.1%] versus 10 [6.2%]; P < 05]. Multivariate analyses found that vancomycin use (odds ratio = 1.64) and smoking (odds ratio = 1.85) were associated with an increased risk of developing minor wound complications. No cases of nephrotoxicity were reported.

CONCLUSIONS: Intrawound vancomycin powder does not appear to reduce PJI/SSI rate in primary total knee arthroplasties, including high-risk groups. Although safe from a renal perspective, intrawound vancomycin was associated with an increase in postoperative aseptic wound complications. Intrawound vancomycin may not be effective in reducing the rate of PJI in primary TKA.

ABSTRACT

OBJECTIVE: To investigate the association between spinal damage and functional capacity in patients with axial spondyloarthritis (axSpA) and to compare the performance of two radiographic scores [modified Stoke AS Spine Score (mSASSS) and Combined AS Spine Score (CASSS)].

METHODS: Radiographs from 101 axSpA patients were scored according to de Vlam et al. for cervical facet joints (CFJ) and mSASSS for vertebral bodies. CASSS was calculated as the sum of both scores. Physical function was assessed by BASFI; disease activity by BASDAI and AS Disease Activity Score (ASDAS); mobility by BASMI; and quality of life by AS Quality of Life (ASQoL). Univariate and multivariate analyses were performed to investigate the association between possible explanatory variables and outcomes.

RESULTS: BASFI correlated strongly with ASQoL (Spearman ρ 0.66) and BASDAI (ρ 0.70), moderately with BASMI (ρ 0.46) and ASDAS (ρ 0.59), and weakly with mSASSS (ρ 0.29) and CASSS (ρ 0.28). A best-fit multivariate model for BASFI, adjusted for symptom duration, age, sex, and smoking status, included BASDAI (B 0.76; P < 0.001), BASMI (B 0.62; P < 0.001) and history of total hip arthroplasty (B 1.22; P = 0.05). Radiographic scores were predictors of BASFI only when BASMI was removed from the model: mSASSS (B 0.03; P = 0.01) and CASSS (B 0.02; P = 0.005).

CONCLUSION: Spinal damage was independently associated with physical function in axSpA but to a lesser extent than disease activity and mobility. Moreover, incorporating CFJ assessment in the mSASSS did not improve the ability to predict function.

ABSTRACT

Video review (VR) of procedures in the medical environment can be used to drive quality improvement. However, first it has to be implemented in a safe and effective way. Our primary objective was to (re)define a guideline for implementing interprofessional VR in a neonatal intensive care unit (NICU). Our secondary objective was to determine the rate of acceptance by providers attending VR. For 9 months, VR sessions were evaluated with a study group, consisting of different stakeholders. A questionnaire was embedded at the end of each session to obtain feedback from providers on the session and on the safe learning environment. In consensus meetings, success factors and preconditions were identified and divided into different factors that influenced the rate of adoption of VR. The number of providers who recorded procedures and attended VR sessions was determined. A total of 18 VR sessions could be organised, with an equal distribution of medical and nursing staff. After the 9-month period, 101/125 (81%) of all providers working on the NICU attended at least 1 session and 80/125 (64%) of all providers recorded their performance of a procedure at least 1 time. In total, 179/297 (61%) providers completed the questionnaire. Almost all providers (99%) reported to have a positive opinion about the review sessions. Preconditions and success factors related to implementation were identified and addressed, including improving the pathway for obtaining consent, preparation of VR, defining the role of the chair during the session and building a safe learning environment. Different strategies were developed to ensure findings from sessions were used for quality improvement. VR was successfully implemented on our NICU and we redefined our guideline with various preconditions and success factors. The adjusted guideline can be helpful for implementation of VR in emergency care settings.

ABSTRACT

INTRODUCTION: In situ simulation (ISS) enables multiprofessional healthcare teams to train for real emergencies in their own working environment and identify latent patient safety threats. This study aimed to determine ISS impact on teamwork, technical skill performance, healthcare staff perception and latent error identification during simulated medical emergencies.

MATERIALS AND METHODS: Unannounced ISS sessions (n=14, n=75 staff members) using a high-fidelity mannequin were conducted in medical, paediatric and rehabilitation wards at Stepping Hill Hospital (Stockport National Health Service Foundation Trust, UK). Each session encompassed a 15 min simulation followed by a 15 min faculty-led debrief.

RESULTS: The clinical team score revealed low overall teamwork performances during simulated medical emergencies (mean±SEM: 4.3±0.5). Linear regression analysis revealed that overall communication (r=0.9, p<0.001), decision-making (r=0.77, p<0.001) and overall situational awareness (r=0.73, p=0.003) were the strongest statistically significant predictors of overall teamwork performance. Neither the number of attending healthcare professionals, their professional background, age, gender, degree of clinical experience, level of resuscitation training or previous simulation experience statistically significantly impacted on overall teamwork performance. ISS positively impacted on healthcare staff confidence and clinical training. Identified safety threats included unknown location of intraosseous kits, poor/absent airway management, incomplete A-E assessments, inability to activate the major haemorrhage protocol, unknown location/dose of epinephrine for anaphylaxis management, delayed administration of epinephrine and delayed/absence of attachment of pads to the defibrillator as well as absence of accessing ALS algorithms, poor chest compressions and passive behaviour during simulated cardiac arrests.

CONCLUSION: Poor demonstration of technical/non-technical skills mandate regular ISS interventions for healthcare professionals of all levels. ISS positively impacts on staff confidence and training and drives identification of latent errors enabling improvements in workplace systems and resources.

ABSTRACT

BACKGROUND: Only a subset of patients with gastric cancer experience long-term benefits from immune checkpoint inhibitors (ICIs). Currently, there is a deficiency in precise predictive biomarkers for ICI efficacy. The aim of this study was to develop and validate a pathomics-driven ensemble model for predicting the response to ICIs in gastric cancer, using H&E-stained whole slide images (WSI).

METHODS: This multicenter study retrospectively collected and analyzed H&E-stained WSIs and clinical data from 584 patients with gastric cancer. An ensemble model, integrating four classifiers: least absolute shrinkage and selection operator, k-nearest neighbors, decision trees, and random forests, was developed and validated using pathomics features, with the objective of predicting the therapeutic efficacy of immune checkpoint inhibition. Model performance was evaluated using metrics including the area under the curve (AUC), sensitivity, and specificity. Additionally, SHAP (SHapley Additive exPlanations) analysis was used to explain the model’s predicted values as the sum of the attribution values for each input feature. Pathogenomics analysis was employed to explain the molecular mechanisms underlying the model’s predictions.

RESULTS: Our pathomics-driven ensemble model effectively stratified the response to ICIs in training cohort (AUC 0.985 (95% CI 0.971 to 0.999)), which was further validated in internal validation cohort (AUC 0.921 (95% CI 0.839 to 0.999)), as well as in external validation cohort 1 (AUC 0.914 (95% CI 0.837 to 0.990)), and external validation cohort 2 (0.927 (95% CI 0.802 to 0.999)). The univariate Cox regression analysis revealed that the prediction signature of pathomics-driven ensemble model was a prognostic factor for progression-free survival in patients with gastric cancer who underwent immunotherapy (p<0.001, HR 0.35 (95% CI 0.24 to 0.50)), and remained an independent predictor after multivariable Cox regression adjusted for clinicopathological variables, (including sex, age, carcinoembryonic antigen, carbohydrate antigen 19-9, therapy regime, line of therapy, differentiation, location and programmed death ligand 1 (PD-L1) expression in all patients (p<0.001, HR 0.34 (95% CI 0.24 to 0.50)). Pathogenomics analysis suggested that the ensemble model is driven by molecular-level immune, cancer, metabolism-related pathways, and was correlated with the immune-related characteristics, including immune score, Estimation of STromal and Immune cells in MAlignant Tumor tissues using Expression data score, and tumor purity.

CONCLUSIONS: Our pathomics-driven ensemble model exhibited high accuracy and robustness in predicting the response to ICIs using WSIs. Therefore, it could serve as a novel and valuable tool to facilitate precision immunotherapy.

ABSTRACT

OBJECTIVE: This study aims to investigate the prevalence of familial cerebral cavernous malformations (FCCMs) in first-degree relatives (FDRs) using familial screening, to describe the distribution of initial symptoms, lesion count on cranial MRI and pathogenic gene in patients.

METHODS: Patients with multiple CCMs who enrolled from the Treatments and Outcomes of Untreated Cerebral Cavernous Malformations in China database were considered as probands and FDRs were recruited. Cranial MRI was performed to screen the CCMs lesions, and whole-exome sequencing was performed to identify CCM mutations. MRI and genetic screening were combined to diagnose FCCM in FDRs, and the results were presented as prevalence and 95% CIs. The Kaplan-Meier (KM) method was used to calculate the cumulative incidence of FCCM.

RESULTS: 33 (76.74%) of the 43 families (110 FDRs) were identified as FCCM (85 FDRs). Receiver operating characteristic analysis revealed three lesions on T2-weighted imaging (T2WI) were the strong indicator for distinguishing probands with FCCM (sensitivity, 87.10%; specificity, 87.50%). Of the 85 FDRs, 31 were diagnosed with FCCM, resulting in a prevalence of 36.5% (26.2%-46.7%). In families with FCCMs, the mutation rates for CCM1, CCM2 and CCM3 were 45.45%, 21.21% and 9.09%, respectively. Furthermore, 53.13% of patients were asymptomatic, 17.19% were intracranial haemorrhage and 9.38% were epilepsy. The mean age of symptom onset analysed by KM was 46.67 (40.56-52.78) years.

CONCLUSION: Based on MRI and genetic analysis, the prevalence of CCMs in the FDRs of families with FCCMs in China was 36.5%. Genetic counselling and MRI screening are recommended for FDRs in patients with more than three CCM lesions on T2WI.

ABSTRACT

INTRODUCTION: Early enteral nutrition (EN) in critically ill adult patients is thought to improve mortality and morbidity; expert guidelines recommend early initiation of EN in critically ill adults. However, the ideal schedule and dose of EN remain understudied.

STUDY OBJECTIVE: Our objective was to evaluate the relationship between achieving 70% of recommended EN within 2 days of intubation (‘early goal EN’) and clinical outcomes in mechanically ventilated medically critically ill adults. We hypothesised that early goal EN would be associated with reduced in-hospital death.

METHODS: We conducted a retrospective cohort study of mechanically ventilated adult patients admitted to our medical intensive care unit during 2013-2019. We assessed the proportion of recommended total EN provided to the patient each day following intubation until extubation, death or 7 days whichever was shortest. Patients who received 70% or more of their recommended total daily EN within 2 days of intubation (ie, ‘baseline period’) were considered to have achieved ‘early goal EN’; these patients were compared with patients who did not (‘low EN’). The primary outcome was in-hospital death; secondary outcomes were successful extubation and discharge alive.

RESULTS: 938 patients met eligibility criteria and survived the baseline period. During the 7-day postintubation period, 64% of all patients reached 70% of recommended daily calories; 33% of patients achieved early goal EN. In unadjusted and adjusted models, early goal EN versus low EN was associated with a lower incidence of in-hospital death (subdistribution HR (SHR) unadjusted=0.63, p=0.0003, SHR adjusted=0.73, p=0.02). Early goal EN was also associated with a higher incidence of successful extubation (SHR unadjusted=1.41, p<0.00001, SHR adjusted=1.27, p=0.002) and discharge alive (SHR unadjusted=1.54, p<0.00001, SHR adjusted=1.24, p=0.02).

CONCLUSIONS: Early goal EN was associated with significant improvement in clinical metrics of decreased in-hospital death, increased extubation and increased hospital discharge alive.

ABSTRACT

BACKGROUND: The prevalence, Medicaid use and mortality risk associated with low forced expiratory volume in 1 s (FEV₁) among young adults aged 20-35 years are not well understood, despite its potential implications for the development of chronic pulmonary disease and overall prognosis.

METHODS: A retrospective cohort study was conducted among young adults aged 20-35 years old, using data from the National Health and Nutrition Examination Survey, National Death Index and Centers for Medicare & Medicaid Services. Participants were categorised into a low FEV₁ group (pre-bronchodilator FEV₁%pred <80%) and a normal FEV₁ group (FEV₁%pred ≥80%). Weighted logistic regression analysis was employed to identify the risk factors associated with low FEV₁, while Cox proportional hazard models were used to calculate the hazard ratio (HR) for Medicaid use and the all-cause mortality between the two groups.

RESULTS: A total of 5346 participants aged 20-35 were included in the study, with 329 in the low FEV₁ group and 5017 in the normal group. The weighted prevalence of low FEV₁ among young adults was 7.1% (95% CI 6.0 to 8.2). Low body mass index (OR=3.06, 95% CI 1.79 to 5.24), doctor-diagnosed asthma (OR=2.25, 1.28 to 3.93), and wheezing or whistling (OR=1.57, 1.06 to 2.33) were identified as independent risk factors for low FEV₁. Over a 15-year follow-up, individuals in the low FEV₁ group exhibited a higher likelihood of Medicaid use compared with those in the normal group (HR=1.73, 1.07 to 2.79). However, there was no statistically significant increase in the risk of all-cause mortality over a 30-year follow-up period (HR=1.48, 1.00 to 2.19).

CONCLUSIONS: A considerable portion of young adults demonstrated low FEV₁ levels, a characteristic that was associated with a higher risk of Medicaid use over a long-term follow-up, yet not linked to an augmented risk of all-cause mortality.
