Prevention of Functional and Cognitive Impairment Through a Multicomponent Exercise Program in Hospitalized Older Adults

The goal of this clinical trial is to learn if a multicomponent exercise program improves functional capacity and cognitive status in hospitalized elderly patients aged 75 and older. Additionally, the study aims to assess the impact of this program on medication use, quality of life, and the overall health outcomes of these patients. The main questions it aims to answer are:

1. Does the multicomponent exercise program enhance functional capacity in hospitalized elderly patients?
2. Which subgroups of patients benefit the most from the intervention (e.g., frail patients, those with cognitive impairment, or malnutrition)?
3. Does participation in the exercise program lead to a reduction in the consumption of medications and instances of iatrogenic complications?
4. How does the exercise program affect the quality of life and sleep quality of the participants?
5. What are the long-term effects of the exercise intervention on muscle mass, balance, and walking speed?
6. Are there measurable changes at the omics level (genomic, proteomic, metabolomic) due to the exercise intervention?

Researchers will compare the multicomponent exercise program to standard care to see if the exercise program leads to significant improvements in functional and cognitive outcomes. This comparison will help determine the effectiveness of the exercise intervention in enhancing the overall well-being of elderly patients during their hospital stay.

Participants will:

• Engage in a structured multicomponent exercise program designed specifically for elderly patients. This program will include activities focused on strength training, balance exercises, and walking to improve mobility and reduce the risk of falls. The exercises will be tailored to the individual capabilities of each participant, ensuring safety and effectiveness.
• Attend supervised exercise sessions several times a week, allowing for individualized attention and adjustments based on each participant\'s abilities and health status. These sessions will be conducted by trained physical therapists who specialize in geriatric care.
• Be monitored for changes in functional capacity using standardized assessments, which will measure improvements in mobility, strength, and overall physical functioning. Assessments will include tools such as the Timed Up and Go Test (TUG), the Berg Balance Scale, and the 6-Minute Walk Test.
• Undergo cognitive assessments to evaluate any changes in cognitive status throughout the intervention and during follow-up periods after discharge. Cognitive evaluations will include tests like the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA).
• Provide information on their medication usage to analyze whether the exercise program can reduce the need for medications or help manage polypharmacy issues commonly faced by elderly patients. This will include a detailed review of current medications and any changes made during the study.
• Participate in surveys and interviews to assess their quality of life, including physical, emotional, and social well-being, before and after the intervention. Quality of life will be measured using validated tools such as the Short Form Health Survey (SF-36) and the EuroQol-5D (EQ-5D).
• Attend follow-up assessments at designated intervals to track their progress and outcomes, ensuring that any long-term benefits of the exercise program are recognized and documented. Follow-ups will occur at 1 month, 3 months, and 6 months post-discharge.

The study will include a diverse sample of participants from multiple centers, ensuring a robust analysis of the intervention\'s effects across different populations. Inclusion criteria will focus on individuals aged over 75 years who are hospitalized in Geriatrics and Internal Medicine services across participating centers (HUN, CHU-T, ULSBM, and HNSM). Participants must be capable of communication and ambulation, either independently or with assistance.

Exclusion criteria will ensure the safety and appropriateness of the intervention. Individuals who explicitly refuse to participate or cannot provide informed consent will be excluded. Additionally, those with a life expectancy of less than three months, terminal illnesses, or significant medical contraindications for exercise will not be eligible. Participants with moderate to severe neurocognitive disorders or disabilities that severely limit mobility will also be excluded to maintain the integrity of the intervention.

Sample Size and Recruitment: This clinical trial aims to recruit a total of 296 patients across the four participating centers. Recruitment will be conducted through hospital admissions, with potential participants identified by medical staff and referred to the research team. Informed consent will be obtained from all participants or their legal representatives prior to enrollment.

Data Collection and Analysis: Data will be collected at baseline, during the intervention, and at follow-up assessments. This will include demographic information, clinical history, baseline functional and cognitive assessments, and post-intervention evaluations. Statistical analyses will be performed to compare outcomes between the intervention and control groups, using appropriate methods to account for potential confounding factors.

Ethical Considerations: This study will adhere to ethical guidelines for research involving human subjects. The protocol will be reviewed and approved by the Institutional Review Board (IRB) at each participating center. Informed consent will be obtained from all participants, ensuring they understand the study\'s purpose, procedures, risks, and benefits.

Expected Outcomes: The findings of this study may provide valuable insights into the benefits of physical activity for elderly patients during hospitalization. By examining the outcomes related to functional capacity, cognitive status, medication use, and quality of life, the study seeks to inform future guidelines and practices for improving the care and rehabilitation of older adults in hospital settings. Additionally, the research may contribute to the understanding of how exercise interventions can positively impact health at the molecular level, potentially leading to new therapeutic approaches for managing health in elderly populations.

Ultimately, the results of this clinical trial could have significant implications for enhancing the quality of care for hospitalized elderly patients, reducing the burden of functional decline, and improving overall health outcomes in this vulnerable population. By demonstrating the effectiveness of a multicomponent exercise program, the study could advocate for the integration of such programs into standard hospital care for older adults, promoting healthier aging and better recovery from acute medical conditions.
