Clinical Trial Summary

Introduction: With the aging of the world population and the increasing incidence of type 2 diabetes mellitus (T2DM) with age, the number of elderly individuals living with diabetes has been considerably rising. It is known that uncontrolled T2DM negatively impacts various health outcomes, including geriatric outcomes such as sarcopenia, frailty, immobility, incontinence, and infections. Current medical literature fails to establish appropriate glycemic targets for different elderly profiles. Although guidelines emphasize the need to individualize targets, there is no concise tool to identify which individuals benefit from each therapeutic approach. Data suggest that frailty is the best predictor of negative outcomes in elderly patients living with T2DM. The Clinical Frailty Scale (CFS) and the 10-minute Targeted Geriatric Assessment (TaGA-10) are validated tools for prognosis in elderly patients and for identifying frail elderly individuals.

Methods: Randomized controlled trial. Elderly individuals diagnosed with T2DM at a tertiary care outpatient clinic will be included. All enrolled patients will undergo geriatric assessment using CFS, TaGA-10, and Charlson Comorbidity Index. Patients will be randomized into usual care and intervention groups, and the intervention involves providing the geriatric assessment to the care team to support their decisions. The adequacy of the therapeutic approach will be measured in one week by reviewing the consult record or interviewing the physician. The clinical impact on the frequency of hypoglycemia, falls, infections, hospitalizations, and mortality will be evaluated at 3 and 6 months by telephone interviews.

Discussion: Current guidelines recommend using age, comorbidities, cognitive, and functional status to individualize therapeutic targets in elderly patients with T2DM; however, it is possible that these variables alone may not be sufficient to classify all elderly individuals in their complexity adequately. A tool with such power and easy to use in clinical practice is necessary.

Clinical Trial Description

All patients included in the research (both intervention and control groups, totaling a sample size of N=220 participants) will undergo geriatric assessment using the CFS and TaGA-10 tools. Using the CFS, we will classify patients with scores of 1 to 3 as "functionally independent," 4 to 5 as "functionally dependent," and scores 6 to 9 as "frail." Patients allocated to the control group will receive usual treatment without any additional procedures.

For the intervention group, before making decisions in the case discussion, we will provide the physician with a document containing the brief geriatric assessment suggesting a care plan as follows:

• Functionally independent: Glycemic targets should be equal to the general population, disregarding age. Consider seeking long-term treatment effects. Target suggested HbA1c around 7.0%.

• Functionally dependent: Consider higher glycemic targets by 0.5% compared to the general adult population. Aim for short- and medium-term treatment effects. Target suggested HbA1c less than 8.0%.

• Frail: Consider higher glycemic targets by 1.5% compared to the general adult population. Aim to reduce treatment complications. Do not expect medium- and long-term treatment effects. Target suggested HbA1c less than 8.5%.

These care plans are based on the Diabetes Canada Clinical Practice Guidelines Expert Committee guideline recommendations.

We will initially approach the physicians at the outpatient clinic to apply the informed consent process and request possible eligible patients from the physician. Each physician will sign a consent form to participate in the entire study. Afterward, we will check the patient's eligibility and apply the informed consent. If any of the participants (physician or patient) disagree with participating in the research, the pair will not be included. Physicians and patients wishing to withdraw consent to participate in the research can do so at any time; in this case, the pair will be treated as lost to follow-up.

The application of the Clinical Frailty Scale, with an estimated duration of 1 minute, will be conducted immediately after obtaining informed consent from the patient. The physician will attend to the patient, and during the discussion with the preceptor, we will apply the TaGA-10 scale in the office. At this time, the patient will also be randomized with the assistance of the RedCap program. For the intervention group, we will provide the physician with a geriatric assessment proposing a glycated hemoglobin target.

Information not requiring in-person assessment will be collected from medical records or during a telephone interview. The adequacy of the therapeutic approach (main outcome) will be measured in one week by reviewing the consult record or interviewing the physician.

The second and third evaluations will be conducted by telephone contact 3 and 6 months after the first visit. During this contact, the incidence of falls, infections, hypoglycemia, hospitalizations, and death will be queried. The data will be stored using the institutional computer in the institutional Google Drive and will be processed and analyzed using the RedCap program. The data will be anonymized for the analysis. ;
