Objective To identify primary care structures and processes that have the highest and lowest impact on chronic disease management and screening and prevention outcomes as well as to assess the feasibility of implementing these structures and processes into practice. Design A two-round Delphi study was conducted to establish consensus on the impact and feasibility of 258 primary care structures and processes. Participants 29 primary care providers, health system leaders and health services researchers in the USA. Outcomes Primary outcomes were (1) consensus on the impact of each structure and process on chronic disease management and screening and prevention outcomes, separately and (2) consensus on feasibility of implementation by primary care practices. Results Consensus on high impact and feasibility of implementation was reached on four items for chronic disease management: ‘Providers use motivational interviewing to help patients set goals’, ‘Practice has designated staff to manage patient panel’, ‘Practice has onsite providers or staff that speak the most dominant, non-English language spoken by patients’ and ‘Practice includes mental health providers and/or behavioural health specialists in care team’ and seven items for screening and prevention: ‘Practice utilizes standing protocols and orders’, ‘Practice generates reports to alert clinicians to missed targets and to identify gaps in care, such as overdue visits, needed vaccinations, screenings or other preventive services’, ‘Practice has designated staff to manage patient panel’, ‘Practice sets performance goals and uses benchmarking to track quality of care’, ‘Practice uses performance feedback to identify practice-specific areas of improvement’, ‘Practice builds quality improvement activities into practice operations’ and ‘Pre-visit planning data are reviewed during daily huddles’. Only ‘Practice has designated staff to manage patient panel’ appeared on both lists. Conclusion Findings suggest that practices need to focus on implementing mostly distinct, rather than common, structures and processes to optimise chronic disease and preventive care.

PURPOSE Pharmacologic therapies for neurofibromatosis type 1-associated plexiform neurofibromas (NF1-PNs) are limited; currently, none are US Food and Drug Administration–approved for adults. METHODS ReNeu is an open-label, multicenter, pivotal, phase IIb trial of mirdametinib in 58 adults (≥18 years of age) and 56 children (2 to 17 years of age) with NF1-PN causing significant morbidities. Patients received mirdametinib capsules or tablets for oral suspension (2 mg/m 2 twice daily, maximum 4 mg twice daily), regardless of food intake, in 3 weeks on/1 week off 28-day cycles. The primary end point was confirmed objective response rate (ORR; proportion of patients with a ≥20% reduction of target PN volume from baseline on consecutive scans during the 24-cycle treatment phase) assessed by blinded independent central review (BICR) of volumetric magnetic resonance imaging. RESULTS Twenty-four of 58 adults (41%) and 29 of 56 children (52%) had a BICR-confirmed objective response during the 24-cycle treatment phase; in addition, two adults and one child had confirmed responses during long-term follow-up. Median (range) target PN volumetric best response was –41% (−90 to 13) in adults and –42% (−91 to 48) in children. Both cohorts reported significant and clinically meaningful improvement in patient- or parent proxy-reported outcome measures of worst tumor pain severity, pain interference, and health-related quality of life (HRQOL) that began early and were sustained during treatment. The most commonly reported treatment-related adverse events were dermatitis acneiform, diarrhea, and nausea in adults and dermatitis acneiform, diarrhea, and paronychia in children. CONCLUSION In ReNeu, the largest multicenter NF1-PN trial reported to date, mirdametinib treatment demonstrated significant confirmed ORRs by BICR, deep and durable PN volume reductions, and early, sustained, and clinically meaningful improvement in pain and HRQOL. Mirdametinib was well-tolerated in adults and children.

Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have inferior outcomes compared with primary ACL reconstruction. The reasons why remain unknown. Purpose: To determine whether surgical factors performed at the time of revision ACL reconstruction can influence a patient’s outcome at 6-year follow-up. Study Design: Cohort study; Level of evidence, 2. Methods: Patients who underwent revision ACL reconstruction were identified and prospectively enrolled between 2006 and 2011. Data collected included baseline patient characteristics, surgical technique and pathology, and a series of validated patient-reported outcome instruments: Knee injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) subjective form, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Marx activity rating score. Patients were followed up for 6 years and asked to complete the identical set of outcome instruments. Regression analysis was used to control for baseline patient characteristics and surgical variables to assess the surgical risk factors for clinical outcomes 6 years after surgery. Results: A total of 1234 patients were enrolled (716 men, 58%; median age, 26 years), and 6-year follow-up was obtained on 79% of patients (980/1234). Using an interference screw for femoral fixation compared with a cross-pin resulted in significantly better outcomes in 6-year IKDC scores (odds ratio [OR], 2.2; 95% CI, 1.2-3.9; P = .008) and KOOS sports/recreation and quality of life subscale scores (OR range, 2.2-2.7; 95% CI, 1.2-4.8; P < .01). Use of an interference screw compared with a cross-pin resulted in a 2.6 times less likely chance of having a subsequent surgery within 6 years. Use of an interference screw for tibial fixation compared with any combination of tibial fixation techniques resulted in significantly improved scores for IKDC (OR, 1.96; 95% CI, 1.3-2.9; P = .001); KOOS pain, activities of daily living, and sports/recreation subscales (OR range, 1.5-1.6; 95% CI, 1.0-2.4; P < .05); and WOMAC pain and activities of daily living subscales (OR range, 1.5-1.8; 95% CI, 1.0-2.7; P < .05). Use of a transtibial surgical approach compared with an anteromedial portal approach resulted in significantly improved KOOS pain and quality of life subscale scores at 6 years (OR, 1.5; 95% CI, 1.02-2.2; P≤ .04). Conclusion: There are surgical variables at the time of ACL revision that can modify clinical outcomes at 6 years. Opting for a transtibial surgical approach and choosing an interference screw for femoral and tibial fixation improved patients’ odds of having a significantly better 6-year clinical outcome in this cohort.

Abstract Background Delirium, an acute brain dysfunction, is proposed to be highly prevalent in clinical care and shown to significantly increase the risk of mortality and dementia. Objectives To report on the global prevalence of clinically documented delirium and delirium-related clinical practices in wards caring for paediatric and adult patients in healthcare facilities. Design A prospective, cross-sectional, 39-question survey completed on World Delirium Awareness Day, 15 March 2023. Participants Clinicians or researchers with access to clinical data. Main Outcome and Measure The primary outcome was the prevalence of clinically documented delirium at 8:00 a.m. (4 h) and 8:00 p.m. (±4 h). Secondary outcomes included delirium-related care practices and barriers to use. Descriptive statistics were calculated and multilevel modelling was completed. Results 1664 wards submitted surveys from 44 countries, reporting on delirium assessments at 8:00 a.m. (n = 36 048) and 8:00 p.m. (n = 32 867); 61% reported use of validated delirium assessment tools. At 8:00 a.m., 18% (n = 2788/15 458) and at 8:00 p.m., 17.7% (n = 2454/13 860) were delirium positive. Top prevention measures were pain management (86.7%), mobilisation (81.4%) and adequate fluids (80.4%). Frequently reported pharmacologic interventions were benzodiazepines (52.7%) and haloperidol (46.2%). Top barriers included the shortage of staff (54.3%), lack of time to educate staff (48.6%) and missing knowledge about delirium (38%). Conclusion and Relevance In this study, approximately one out of five patients were reported as delirious. The reported high use of benzodiazepines needs further evaluation as it is not aligned with best-practice recommendations. Findings provide a benchmark for future quality improvement projects and research.

Abstract Background Cardiopulmonary exercise testing (CPET) has emerged as an important tool for risk stratification and prognosis assessment in patients with cardiac diseases. The Weber and Ventilatory Functional Classification have been correlated with outcomes in patients with Heart Failure (HF). Weber classification is based on VO2: Weber class A, peak VO2 &gt;20 mL/kg per minute; class B, peak VO2 16–20 mL/kg per minute; class C, peak VO2 10–16 mL/kg per minute; and class D, peak VO2 ≤10 mL/kg per minute and Ventilatory classification on VE/VCO2 slope I-IV (Figure A). Although VO2 and VE/VCO2 variables have found altered in the amyloidosis population, the applicability of this classification in a cohort of amyloidosis patients and its correlation with all-cause mortality have not been explored. Purpose To evaluate if the Weber and Ventilatory Classification of HF predicts mortality amyloidosis patients. Methods 194 with diagnosis of amyloidosis who underwent CPET from February 2010 to February 2024 were included in this retrospective cohort study. Patients with at least one CPET complete data were included in the analysis. Data on the type of amyloidosis, comorbidities, and echocardiogram were retrieved from medical records. Cohort was divided into two groups according to the Weber Classification: Weber Class A/B and Weber Class C/D. Individuals with CPET studies after heart transplant were excluded from the analysis. Statistical analyses including Fisher’s exact test, chi-square, Tukey-Kramer (TK), Cox regression model analysis, proportional hazards model for time to event, and Kaplan–Meier curves were performed. A p-value &lt;0.05 was considered significant. Results Out of the 194 patients, 94 were classified as Weber A-B and 100 as Weber B-C. The age at stress test was similar between the groups: Weber A/B 62.9 ± 11.7 years and Weber C/D 62.3 ± 10.7 years (p=0.087). Ejection Fraction was similar between groups, 32% and 28.9% in A-B and C-D respectively (p =0.207). Higher levels of NT-proBNP were found in the Weber C/D group. The prevalence of comorbidities was balanced among the groups except chronic kidney disease, which was higher in Weber Class C/D (40%) vs (20.2%) in Weber Class A/B (Table 1). Cox analysis revealed a strong association between higher Weber class and the outcome HR 2.36 (1.18 – 4.71) p=0.014. For Higher Ventilatory Class (Group III-IV) similar results were found HR 2.95 (1.60 – 5.45) p=0.005(Table 2). Mortality was significantly higher during the follow-up in the Weber C/D group (25%) vs (10%) in the Weber A-B group p=0.007(Figure D). Conclusion Weber and ventilatory Classification based on CPET, besides predicting outcomes in patients with cardiac disease, are strong predictors of mortality in patients with amyloidosis. These findings suggest that this patient group benefits from earlier stratification to assess prognosis and the potential requirement for transplant independently from other factors.
