Education for Prevention and Treatment of Frailty

Study Overview
=================
Brief Summary
-----------------
Frailty is a condition with a high prevalence in older adults, leading to higher vulnerability and increasing the risk of adverse health outcomes and disabilities. The aging of the population in Spain is accelerating quickly, consequently, it is necessary to advise the population on the appropriate path to healthy aging, free of fragility and their secondary problems.

Detailed Description
-----------------
To evaluate the efficacy and efficiency of a Fragsalud program for the prevention and multifactorial treatment of frailty in people over 65 years of age living in the community compared to the usual treatment. Material and methods: A Single blind randomized, two-arm clinical trial; control group and intervention group, multicenter, with 15 months of follow-up, with evaluations blinded at the beginning, and in the follow-up at 12 and 15 months. A recruitment of 196 people over 65 years of age with criteria of pre-frailty or frailty according to Fried's criteria. The Fragsalud education program will be taught in the intervention group; while control group will follow the usual health care. The evolution of the criteria of frailty, cognitive state, eating pattern, emotional state, quality of sleep, perceived social support, quality of life, functional capacity in daily life, adverse results, assessment of self-efficacy and cost-utility analysis variables will be evaluated. Possible confounding factors such as sociodemographic variables, comorbidity and polymedication will be controlled. Intention-to-treat analysis will be performed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Control Group<br>Participants who do not receive attention from the Fragsalud program. The control group follows the usual care and preventive measures in Primary Care, according to different protocols implemented and the criteria of nurses and family doctors responsible for their care. | |
| Experimental: Intervention Group<br>The FRAGSALUD Programme is a multidomain intervention programme, which covers the prevention and treatment of frailty from different aspects, fundamentally from a physical and cognitive aspect and to maintain social integration, although other modifiable factors that are related to the presence of fragility such as hearing impairment, visual deficit or depression. | Other: Health intervention programme: FRAGSALUD<br>* The FRAGSALUD Program consists in two parts, a first part of health education that will be taught in a group in four sessions, and a second part of individual treatment and follow-up, individual consultations will have a bimonthly periodicity until reaching one year, at which time that the program ends and a final evaluation will be carried out to assess whether the changes are maintained 15 months after the start.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the change of baseline Fried frailty criteria at 6 months | - Fried frailty criteria adapted to the Spanish population: subjects are considered non-frail when no criteria are present, pre-frail if they meet 1 or 2 of the criteria, and frail if they meet 3 to 5 criteria. Fried frailty criteria are divided into 5: Weight loss, Exhaustion, Physical Activity, Walking time, and Muscle weakness. | Preintervention/Postintervention (0 and 6 months) | 
| Evaluation of the change of baseline Fried frailty criteria at 12 months | - Fried frailty criteria adapted to the Spanish population: subjects are considered non-frail when no criteria are present, pre-frail if they meet 1 or 2 of the criteria, and frail if they meet 3 to 5 criteria. Fried frailty criteria are divided into 5: Weight loss, Exhaustion, Physical Activity, Walking time, and Muscle weakness. | Preintervention/Postintervention (0 and 12 months) | 
| Evaluation of the change of baseline weight change at 6 months | Unintentional weight loss of 5% or more in the last year: it is calculated using the difference between the current weight and that recorded in the medical record in the last year.

| Evaluation of the change of baseline Functional capacity in daily life (Exercise, physical inactivity and sleep) at 6 months | - Assessment of exercise, physical inactivity and sleep that will be carried out using accelerometers for 7 days at the beginning, a year and 15 months.

This monitor provides the end user with raw accelerometry data. In this study, the accelerometer will be configured at 40 Hz. For data processing, the system developed for the PREDIMEDPLUS study will be used. The data processing is done with an open source package in R, GGIR version 1.5-12. | Preintervention/Postintervention (0 and 6 months) |
