Background: Nonagenarians are a rapidly expanding population in the United States. These patients are met with increasing rates of hip arthritis, necessitating the need for total hip arthroplasty (THA). However, there is currently limited information on hospitalization information and perioperative complications in this population. Methods: In this retrospective study, we used the Nationwide Inpatient Sample (NIS) database from 2016-2019 to analyze the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing THAs who were categorized as nonagenarians, and those who were not.
Results: The NIS database identified 309 100 patients who underwent THAs from 2016-2019. Of those, 1864 patients (.6%) were nonagenarian, while the remaining 307 236 patients were included under the non-nonagenarian category (control). The mean age in the nonagenarian group was 90 years compared to the control group which had a mean age of 65.8 years. There was an increased incidence of mortality rate (nonagenarian group .2%, control group .03%, < .001), myocardial infarction (MI) (nonagenarian group .1%, control group .02%, = .01), acute renal failure (ARF) (nonagenarian group 5.4%, control group 1.6%, < .001), blood anemia post-operatively (nonagenarian group 28.9%, control group 17.2%, < .001), and deep vein thrombosis (DVT) (nonagenarian group .48%, control group .07%, < .001) in the nonagenarian group. The COC for the nonagenarian group was higher than that in the control group ( < .001). The mean LOS was longer in the nonagenarian group (3.1 days) in comparison to the control group (1.96 days) ( < .001).
Conclusions: Nonagenarians had significantly higher rates of both orthopedics and medical complications than the younger patients undergoing THAs. In addition, the nonagenarian group incurred higher COC. This information is useful for the providers to make informed decisions regarding patient care and resource utilization for nonagenarian patients undergoing THAs.

IRCCS Centro Cardiologico Monzino, Department of Cardiovascular Surgery, Milan 20138, Italy; Department of Biomedical, Surgical and Dental Sciences, University of Milan, Milan 20100, Italy.
Purpose: To compare the overall survival and the risk of all-cause and heart failure-specific hospitalization in nonagenarian patients hospitalized for symptomatic severe aortic stenosis (AS) who underwent transcatheter aortic valve implantation (TAVI) or conservative treatment.
Methods: Population-based retrospective cohort study based on healthcare utilization databases of the Italian region of Lombardy. The cohort included all nonagenarians hospitalized for AS between 2017 and 2021, who underwent TAVI within 90 days from first diagnosis or conservative treatment.
Distal Access Catheter Improves Balloon Guide and Stent Retriever Thrombectomy Outcomes in Nonagenarians.

Background And Purpose: The safety and effectiveness of endovascular techniques in elderly patients with large vessel occlusion (LVO) remain controversial. We investigated the angiographic and clinical outcomes of nonagenarians treated with different endovascular techniques using a balloon guide catheter (BGC), distal aspiration catheter (DAC), and/or stent retriever (SR).
Methods: We analyzed the data from the Registry of Combined versus Single Thrombectomy Techniques (ROSSETTI) of consecutive nonagenarian patients with anterior circulation LVO and compared the outcomes of those treated with BGC+noDAC+SR (101-group), BGC+DAC+SR (111-group), and noBGC+DAC+SR (011-group).
Prognostic Factors for Mortality in Patients Aged 90 Years and Older with Proximal Femoral Fractures Undergoing Surgery: A Retrospective Study.

Proximal femoral fractures (PFFs) among individuals aged ≥90 years are becoming more common with an aging population and are associated with high morbidity and mortality. This study analyzed the prognostic factors influencing survival in nonagenarian patients undergoing surgery for PFFs. We enrolled 285 patients who underwent surgery between 2016 and 2022.

This document determines the causes of mortality (2008-2022) and calculate per capita health expenditure (2013-2021) in octogenarians, nonagenarians and centenarians in the Colombian population, considering year, gender and age group. For this nationwide retrospective descriptive observational study, epidemiological regions, urban/rural areas and morbidities were also studied. A mean of 75,552 deaths was observed from 2008 to 2022.

Background: Little is known about how younger and older hospitalized patients differ with respect to reasons for admission, comorbidities, diagnostics, treatment and intercurrent problems.
Objective: The aim of the study was to compare the previously named characteristics in the clinical profile of patients > 90 years old (nonagenarians) with a control group of patients 70-75 years old admitted to an emergency hospital department for internal medicine and cardiology.
Material And Method: The study included all consecutive nonagenarians and gender-matched control patients who were admitted during 2011.
