AI Article Synopsis
- Multimorbidity is common among older adults and significantly increases the risk of hospitalisation, readmission, and longer hospital stays.
- A study involving 8807 Brazilians aged 50 and older found that factors like gender, relationship status, alcohol consumption, and having multiple chronic conditions were linked to higher hospitalisation rates.
- Network analysis revealed five disease groups that are particularly associated with increased risks for hospitalisation and readmission, highlighting the importance of understanding sociodemographic factors and health conditions in this population.
Article Abstract
Multimorbidity is highly prevalent in older adults and can lead to hospitalisation. We investigate the prevalence, associated factors, and multimorbidity pattern associated to hospitalisation, readmission, and length of stay in the population aged 50 years and older. We analysed baseline data (2015-2016) from the ELSI-Brazil cohort, a representative sample of non-institutionalised Brazilians aged ≥ 50 years. In total, 8807 individuals aged ≥ 50 years were included. Poisson regression with robust variance adjusted for confounders was used to verify the associations with hospitalisation. Multiple linear regression was used to analyse the associations with readmission and length of stay. Network analysis was conducted using 19 morbidities and the outcome variables. In 8807 participants, the prevalence of hospitalisation was 10.0% (95% CI 9.1, 11), mean readmissions was 1.55 ± 1.191, and mean length of stay was 6.43 ± 10.46 days. Hospitalisation was positively associated with male gender, not living with a partner, not having ingested alcoholic beverages in the last month, and multimorbidity. For hospital readmission, only multimorbidity ≥ 3 chronic conditions showed a statistically significant association. Regarding the length of stay, the risk was positive for males and negative for living in rural areas. Five disease groups connected to hospitalisation, readmission and length of stay were identified. To conclude, sociodemographic variables, such as gender, age group, and living in urban areas, and multimorbidity increased the risk of hospitalisation, mean number of readmissions, and mean length of stay. Through network analysis, we identified the groups of diseases that increased the risk of hospitalisation, readmissions, and length of stay.

Medical and Surgical Episodes Among Hospital Participants in the Bundled Payments for Care Improvement-Advanced Program.
JAMA Netw Open
December 2024
Center for Advancing Health Services, Policy & Economics Research, Institute for Public Health, Washington University, St Louis, Missouri.
Importance: Hospital participation in the Bundled Payments for Care Improvement-Advanced (BPCI-A) initiative has been associated with modest savings and stable clinical outcomes overall, but it is unknown whether the program performs differently for medical and surgical or procedural (henceforth, surgical) episodes.
Objective: To assess the association of BPCI-A participation with Medicare spending and clinical outcomes for medical and surgical episodes.
Design, Setting, And Participants: This retrospective difference-in-differences cohort study utilized 100% Medicare fee-for-service inpatient claims for episodes initiated between January 1, 2017, and September 30, 2019, and included 90 days of follow-up.
Reduced-port laparoscopic right colonic resection with D3 lymph node dissection and transvaginal specimen extraction (NOSES VIIIa) for right colon cancer: clinical features.
Tech Coloproctol
December 2024
Department of Faculty Surgery No. 2, I.M. Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russia.
Background: Reduced-port laparoscopic surgery (RPLS) uses the minimum possible number of ports or small-sized ports in laparoscopic surgery. The combination of RPLS and natural orifice specimen extraction (NOSE) minimizes the procedural damage.
Methods: A total of 17 patients diagnosed with right colon cancer were included: 5 patients in the RPLS + NOSE group and 12 patients in the conventional laparoscopic surgery (CL) + mini-laparotomy (ML) group.
Nail-plate combination constructs versus single traditional constructs for distal femur fractures: a systematic review and meta-analysis of comparative studies.
Arch Orthop Trauma Surg
December 2024
Department of Orthopedic Surgery, University of Michigan, Ann Arbor, MI, USA.
Objectives: Distal femur fractures (DFF) are frequently treated surgically with single traditional constructs (STC), such as with a lateral plate or intramedullary nail, although nail-plate combination constructs (NPCC) are gaining attention. The purpose of this study is to compare outcomes between NPCC and STC for surgical fixation of DFF to guide surgeon decision-making.
Methods: Data Sources: This study is a systematic review and meta-analysis using PubMed, CINAHL, MEDLINE, Web of Science, Science Direct, and SPORTDiscus from database inception until January 10th, 2024.
[Minimally invasive trans-axillary approach and ultra-fast-track management: a new paradigm for mitral valve disease treatment].
G Ital Cardiol (Rome)
January 2025
Cardiochirurgia, Azienda Ospedaliero Universitaria delle Marche, Università Politecnica delle Marche, Ancona.
Background: The introduction of transcatheter procedures has focused on patient expectations for treatments with a less invasive approach and faster recovery. The aim of this study was to assess the short- and medium-term results in patients who underwent trans-axillary mitral valve repair with application of the ultra-fast-track protocol.
Methods: Data from 431 patients undergoing isolated trans-axillary mitral valve repair or associated with tricuspid valve treatment between January 2018 and December 2023 were prospectively collected.
Clinical Implications of the Obstructive Pattern on Chest Radiography in Children Aged 3-59 Months With Severe Lower Respiratory Tract Infections.
Pediatr Pulmonol
December 2024
Department of Emergency Medicine, Ajou University School of Medicine, Suwon, Republic of Korea.
Objectives: To investigate the clinical implications of the obstructive pattern on plain chest radiography, defined as peribronchial cuffing or hyperinflation, in young children with severe lower respiratory tract infections (LRTIs).
Methods: We reviewed all children aged 3‒59 months with LRTIs who underwent radiography and polymerase chain reaction in a Korean emergency department from 2016 through 2020. The radiographs were read as consolidation, peribronchial cuffing, or hyperinflation, with each interrater reliability computed.
