In a proactive measure against the growing health challenge of frailty in older adults, researchers in Florence, Italy, are launching a new longitudinal cohort study. The initiative aims to identify frail individuals early among 75-year-olds in a specific neighborhood through a multi-step screening process. This research, an adaptation of the Integrated Care for Older People (ICOPE) model, is designed to create tailored, multi-component care pathways for each patient, fostering collaboration among healthcare professionals and general practitioners.
Frailty, characterized by a decline in physical and mental reserve, increases vulnerability to adverse health outcomes, including falls, hospitalization, and reduced quality of life. The World Health Organization (WHO) has highlighted the urgent need for new interventions for endemic pathogens and health conditions affecting aging populations, underscoring the significance of studies like this. While not directly a pathogen, frailty is a critical health concern for the elderly demographic globally. According to a study published in *eBioMedicine*, the WHO recently identified top endemic pathogens requiring new vaccines, reinforcing the global focus on widespread health threats. While frailty isn’t an infectious disease, it represents a significant public health burden that requires continuous attention and innovative solutions.
Study Design and Objectives
The study, a single-center prospective longitudinal cohort investigation, is being conducted at the House of Community (HoC) Le Piagge, a community health center in Florence. This facility emphasizes continuity of care, integration among health professionals, and the promotion of health literacy and community engagement. The research will unfold in two phases: an initial screening followed by a more in-depth multidimensional assessment.
The primary objectives include determining the prevalence of frailty among 75-year-olds using a first-level screening tool, which will serve as baseline data for subsequent care pathways. Researchers also aim to analyze the characteristics and health outcomes of frail individuals identified through the screening, pinpointing determinants associated with frailty progression. A key aspect of the study is exploring the relationship between health literacy and frailty, examining how health literacy influences outcomes from the multidimensional assessment.
Participant Recruitment and Assessment
The study targets all 75-year-olds residing in the HoC Le Piagge’s reference area who are apparently self-sufficient and without physical or mental disabilities. This age group was selected due to the higher prevalence of frailty in individuals aged 75–84, as well as for the feasibility of identifying initial stages of frailty that can benefit from early, non-pharmacological interventions. An annual recruitment of 75-year-olds is planned, with follow-ups for previously recruited cohorts to monitor for signs of autonomy loss over time. The estimated participation rate is between 20% and 30% of the more than 400 subjects initially contacted, with an anticipated attrition rate of 20% due to factors such as loss of contact or health-related reasons.
Initial recruitment involves telephone contact, repeated up to three times, to explain the study and gain verbal consent. Those who agree are scheduled for an appointment at the HoC for the first-level screening. This screening includes a validated questionnaire developed by the Tuscany regional commission, which assesses factors such as vision, fatigue, memory problems, fall history, walking difficulties, and medication intake. A score of 6.5 or higher indicates a higher likelihood of frailty. Additionally, the Chair Rise Test, recommended by the ICOPE framework, will measure lower limb muscle strength, and the Single Item Literacy Screening (SILS) will gauge health literacy.
Participants testing positive in the first-level screening will proceed to a second, more comprehensive multidimensional assessment. This phase delves into various frailty domains using tools such as the Mini Cog Test for cognitive function, the Short Physical Performance Battery (SPPB) for physical performance, and the Basic and Instrumental Activities of Daily Living (BADL/IADL) to assess autonomy. Nutritional risk will be evaluated using the Malnutrition Universal Screening Tool (MUST), and the SARC-F5 will screen for sarcopenia. Vision and hearing will be assessed with the WHO simple eye chart and the Hearing Handicap Inventory for the Elderly (HHIE-It), respectively. The Geriatric Depression Scale (GDS-5) will screen for depression. Health literacy will be further explored using the European Health Literacy Survey Questionnaire (HLS-EU-Q16) and the Newest Vital Sign (NVS).
Clinical Implications and Future Directions
Based on the results of the multidimensional assessment, general practitioners, who are kept informed throughout the process, may recommend a specialist geriatrician examination. This examination, offered free of charge at HoC Le Piagge, aims to further assess the patient’s health needs and care complexity, leading to a personalized care plan developed collaboratively with other primary care professionals. Follow-up assessments are slated for 6 and 12 months after the initial screening, marking the conclusion of the study’s data collection phase. The findings will be disseminated through national conferences and peer-reviewed journals, contributing valuable insights into effective frailty prevention and management strategies.
This study aligns with broader efforts to address health challenges like antimicrobial resistance (AMR), which, according to the [who.int](https://www.who.int/publications/i/item/9789240116337) 2025 Global Antibiotic Resistance Surveillance Report, remains a significant global health threat. Both frailty and AMR underscore the importance of robust public health surveillance and intervention strategies. By identifying and addressing frailty early, this research has the potential to improve the quality of life for older adults and reduce healthcare burdens, fostering healthier aging communities.
