RESUMO
BACKGROUND: Little research has been undertaken on the benefits of frailty management within different hospital settings. The objective of this study is to provide evidence on the viability and effectiveness of frailty management in non-geriatric hospital settings on mortality and functional decline after discharge. METHODS: Data from the FRAILCLINIC (NCT02643069) study were used. FRAILCLINIC is a randomized controlled trial developed in non-geriatric hospital inpatient settings (emergency room, cardiology and surgery) from Spain (2), Italy (2) and the United Kingdom (1). Inpatients must met frailty criteria (according to the Frailty Phenotype and/or FRAIL scale), ≥75 years old. The control group (CG) received usual care. The intervention group (IG) received comprehensive geriatric assessment (CGA) and a coordinated intervention consisting in recommendations to the treating physician about polypharmacy, delirium, falls, nutrition and physical exercise plus a discharge plan. The main outcomes included functional decline (worsening ≥5 points in Barthel Index) and mortality at 3 months. We used multivariate logistic regression models adjusted by age, gender and the Charlson index. Intention-to-treat (ITT) and per-protocol (PP) analyses were used. RESULTS: Eight hundred twenty one participants (IG: 416; mean age 83.00 ± 4.91; 51.44% women; CG: 405; mean age 82.46 ± 6.03; 52.35% women) were included. In the IG, 77.16% of the participants followed the geriatric team's recommendations as implemented by the treating physicians. The intervention showed a benefit on functional decline and mortality [OR: 0.67(0.47-0.96), P-value 0.027 and 0.29(0.14-0.57), P-value < 0.001, respectively) when fully followed by the treating physician. A trend to benefit (close to statistical significance) in functional decline and mortality were also observed when any of the recommendations were not followed [OR (95% CI): 0.72 (0.51-1.01), P-value: 0.055; and 0.64 (0.37-1.10), P-value: 0.105, respectively]. CONCLUSIONS: An individualized intervention in frail in-patients reduces the risk of functional deterioration and mortality at 3 months of follow-up when a care management plan is designed and followed.

BACKGROUND: Frailty resulting from the loss of muscle quality can potentially be delayed through early detection and physical exercise interventions. There is a demand for cost-effective tools for the objective evaluation of muscle quality, in both cross-sectional and longitudinal assessments. Literature suggests that quantitative analysis of ultrasound data captures morphometric, compositional, and microstructural muscle properties, while biological assays derived from blood samples are associated with functional information. OBJECTIVE: This study aims to assess multiparametric combinations of ultrasound and blood-based biomarkers to offer a cross-sectional evaluation of the patient frailty phenotype and to track changes in muscle quality associated with supervised exercise programs. METHODS: This prospective observational multicenter study will include patients aged 70 years and older who are capable of providing informed consent. We aim to recruit 100 patients from hospital environments and 100 from primary care facilities. Each patient will undergo at least two examinations (baseline and follow-up), totaling a minimum of 400 examinations. In hospital environments, 50 patients will be measured before/after a 16-week individualized and supervised exercise program, while another 50 patients will be followed up after the same period without intervention. Primary care patients will undergo a 1-year follow-up evaluation. The primary objective is to compare cross-sectional evaluations of physical performance, functional capacity, body composition, and derived scales of sarcopenia and frailty with biomarker combinations obtained from muscle ultrasound and blood-based assays. We will analyze ultrasound raw data obtained with a point-of-care device, along with a set of biomarkers previously associated with frailty, using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. Additionally, we will examine the sensitivity of these biomarkers to detect short-term muscle quality changes and functional improvement after a supervised exercise intervention compared with usual care. RESULTS: At the time of manuscript submission, the enrollment of volunteers is ongoing. Recruitment started on March 1, 2022, and ends on June 30, 2024. CONCLUSIONS: The outlined study protocol will integrate portable technologies, using quantitative muscle ultrasound and blood biomarkers, to facilitate an objective cross-sectional assessment of muscle quality in both hospital and primary care settings. The primary objective is to generate data that can be used to explore associations between biomarker combinations and the cross-sectional clinical assessment of frailty and sarcopenia. Additionally, the study aims to investigate musculoskeletal changes following multicomponent physical exercise programs.

RESUMO
OBJECTIVES: To evaluate the degree of compliance with the current guidelines regarding venous thromboembolism (VTE) prophylaxis in medical patients during admission and to identify risk factors linked to complications of VTE prophylaxis. DESIGN: Prospective cohort study. SETTING: The Internal Medicine Department of the University Hospital of Santiago de Compostela (tertiary referral hospital). PARTICIPANTS: A total of 396 hospitalised, elderly patients who did not undergo surgery and had no active or previous oral anticoagulation or low molecular weight heparin (LMWH) treatment (during the previous year) and who received VTE prophylaxis during admission. PRIMARY AND SECONDARY OUTCOME MEASURES: The degree of compliance with the current guidelines was estimated by calculating PADOVA and IMPROVE indexes in all cases. We analysed the development of the following complications: major and minor bleeding, major and minor haematoma and decrease of platelet count. RESULTS: We found that VTE prophylaxis was correctly indicated in 88.4% of patients. We found two (0.5%) cases with major bleeding, 17 (4.3%) with minor bleeding, 30 (7.6%) with decreased platelet count, 29 (7.3%) with major haematoma and 82 (20.7%) with minor haematoma. After multivariate logistic regression analysis, the presence of major haematomas was linked to obesity (OR 4.1; 95% CI 1.8 to 9.2, p=0.001), concomitant antiplatelet treatment (OR 2.7; 95% CI 1.1 to 6.5, p=0.03) and enoxaparin use (OR 3.5; 95% CI 1.1 to 10.9, p=0.029), and the presence of minor haematomas was associated with PADOVA index <4 points (OR 3.1; 95% CI 1.5 to 6.4, p=0.003) and diabetes mellitus (OR 2; 95% CI 1.1 to 3.7, p=0.031). CONCLUSIONS: Complications during VTE prophylaxis in elderly hospitalised medical patients are frequent even with correct application of current guidelines. The main factors linked to haematomas were obesity and concomitant antiplatelet treatment, the presence of which should lead physicians to exercise extreme caution. The use of tinzaparin for VTE prophylaxis in these patients could have a better safety profile.
