Further study details as provided by Maria del Carmen Garcia-Pena, Coordinación de Investigación en Salud, Mexico:

Primary Outcome Measures:
  • Change in hand grip strength (HS) as a physical performance test [ Time Frame: Basal and Six months ]
    A standardized technique and digital dynamometers (Exacta TM) wil lbe used, and the best result of two tests in the dominant hand will be used for analysis. No cut-off points will be applied; instead the variable will be assessed as a continuous one with kilograms as the units of measure.

Secondary Outcome Measures:
  • Evaluation of individual and institutional impact [ Time Frame: Six Months ]

    Evaluate the impact of a scheme based on internal consultation geriatricians and home visiting nurses oriented elders 70 and over, in terms of individual outcomes and health services:

    a. Individual Impacts:

    a.1 Primary:

    • Fragility

Other Outcome Measures:
  • Quantify hospital readmissions [ Time Frame: One Year ]
    Estimate the readmission to hospital adverse events in adults older than 70 years, underwent surgery and its comparison group from discharge from service

Enrollment: 1400
Study Start Date: June 2013
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Basal phase
Integrated measurement of all variables involved impact and frequency of prior use of health services and specifically to the emergency room, service access, patient characteristics, features for the classification of frailty, cognitive impairment and depression, why consultation, triage scale level on admission to the service and to the service variables in terms of length of stay, diagnosis and medical management, and related services with internal consultants percentage of inpatients discharged or deceased, in further analysis the researchers undertake group estimating frequency of use and the identification of factors associated with the use of emergency departments and adverse events
Other: Factors associated with the use of emergency departments
Participants who were assigned to the intervention will be evaluated jointly by the medical service by a medical specialist in geriatrics and a nurse trained in gerontology and geriatrics. The doctor will monitor the apparition and / or aggravation of any geriatric syndromes already established by the specialty in geriatrics, namely, polypharmacy, delirium, dementia, depression, risk of falls, etc.. The nurse will monitor and follow up in four areas I. medical issues (pressure ulcers, infusion, mobility); II. Mental and emotional state and coping strategies with hospitalization; III. functionality, and IV. Atmosphere (A. Service status, architectural difficulties for mobility, bathing etc. B. Support Network, caregiver, and C. hardship)

Detailed Description:

- Usual care as the comparison group

Usual care or standard refers to those processes or services that the elderly claimant receives the IMSS services network, after the acute phase of their illness has been stabilized and is defined that can be discharged from the emergency department, following clinical and therapeutic recommendations for improving their health.

  • Elders risk population for emergency

The aging population brings a major change in health conditions and social conditions around the elderly, the analysis of the elderly population is considered according to functionality and risks of old age, when it comes to care services emergency, care becomes more critical as the elderly are older, have been identified adults of 70 and over as more vulnerable to health services, especially for the emergency services as they do not exhibit classic patterns to acute events of prevalent diseases.

  • Functionality and dependence

The commitment of the functionality in adults older than 65 may be present in 5% of cases, while in over 70 years this figure rises to 50% or more. Functional impairment may be a "marker" of the effect of systemic disease on the patient and is also an indicator of severity of disease because it measures the ability of independence

The accumulation of normal aging characteristics define a threshold, which once pierced, tends to increase the propensity for loss of functional abilities due to aging. However, not everyone ages the same way, since factors such as inherited genetic capital, especially the accumulation of risks associated with lifestyle and work activities, and the opportunity to identify the disease in its period latency coupled with the accessibility and use of health services, can delay or exacerbate the loss of functionality and increase the dependency of the elderly.

  • Quality of life of older

Frailty in the elderly is a state of increased susceptibility due to less booking multiple physiological systems resulting in lower resilience, negative energy balance, sarcopenia, decreased strength and reduced exercise tolerance. Frailty is associated with adverse health outcomes such as institutionalization, falls, reduced performance status and increased mortality.
