Background: Numerous frailty screening instruments are available, but their applicability for identifying frailty in patients with end-stage renal disease (ESRD) is unknown. We aimed to investigate the diagnostic accuracy of three instruments used for frailty screening in an ESRD population.
Methods: The study was conducted in 2013 in a teaching hospital in The Netherlands and included patients receiving haemodialysis, peritoneal dialysis and pre-dialysis care. We determined the sensitivity and specificity of three screening instruments: the Groningen Frailty Indicator (GFI), the Identification of Seniors at Risk-Hospitalized Patients (ISAR-HP) and the Veiligheidsmanagementsysteem (VMS), which is a safety management system for vulnerable elderly patients. The Frailty Index was the gold standard used.
Results: The prevalence of frailty was 37% in a total of 95 participants with ESRD [mean age 65.2 years (SD 12.0), 57% male]. Frailty prevalence in participants ≥65 years of age and <65 years of age was 44% and 28%, respectively (P = 0.11). Sensitivity and specificity for frailty of the GFI were 89% and 57%, respectively; ISAR-HP 83% and 77%, respectively; and VMS 77% and 67%, respectively.
Conclusions: Although the GFI showed the highest sensitivity, it is not yet possible to propose a firm choice for one of these screening instruments or specific items due to the small scale of the study. Since there is a high prevalence of frailty in ESRD patients, translation and testing of the effectiveness of screening using the GFI in the prognostication and prevention of development or deterioration of frailty in this population should be the next step.

Using the hospital frailty risk score to assess oesophago-gastric cancer patient outcomes: a retrospective cohort study.
Int J Surg

Department of Upper Gastrointestinal Surgery, Royal Marsden NHS Foundation Trust, London, United Kingdom.
Background: The inclusion of clinical frailty in the assessment of patients planned for major surgery has proven to be an independent predictor of outcome. Since approximately half of all patients in the UK diagnosed with oesophagogastric (OG) cancer are over 75 years of age, assessment of frailty may be important in selection for surgery.
Materials And Methods: This retrospective cohort study applied the Hospital Frailty Risk Score to data obtained from the NHS Secondary Uses Service electronic database for patients aged 75 years or older undergoing oesophagectomy and gastrectomy between April 2017 and March 2020.
Background: Although frailty assessment is crucial for understanding critically ill patients' prognosis, traditional frailty measures require substantial efforts and time from health care professionals. To address this limitation, the laboratory frailty index (FI-LAB) based on laboratory clinical data was developed. However, knowledge regarding its correlation with health outcomes among critically ill older patients is limited.

Department of Epidemiology, Rollins School of Public Health, Emory University, Atlanta.
Objectives: Posttraumatic stress disorder (PTSD) may affect antiretroviral therapy (ART) response and clinical outcomes for veterans with HIV (VWH) receiving care in the Department of Veterans Affairs (VA). Objectives are to estimate the associations between PTSD and ART nonadherence, modifications, and failure; measure effect modification by number of deployments and combat exposure; and examine how these associations vary over time.
Design: In this prospective cohort study of all VWH on ART who deployed to Iraq and Afghanistan and receive care in the VA (n = 3206), patients entered at ART initiation and were censored in December 2022, totaling 22 261 person-years of follow-up.
Scale-based screening and assessment of age-related frailty.

As the population ages, the prevalence of age-related frailty increases sharply, which increases the risk of poor health status of older adults, such as disability, falls, hospitalization, and death. Across the globe, frailty is moving toward the forefront of health and medical research. Currently, frailty is believed to be preventable and reversible, so the early identification of frailty is critical.

The Geriatric Services Hub (GSH) is a novel program in Singapore that delivers frailty screening, comprehensive geriatric assessment and coordinated care for community-dwelling older persons with bio-psycho-social needs. We aimed to evaluate the effects of the GSH on healthcare use.
