Therapeutic Interventions for Frail Elderly Patients: Part II. Ongoing and Unpublished Randomized Trials
Section snippets
Methods
The ClinicalTrials.gov registry was queried using the following search string: (frail OR frailty OR sarcopenic OR sarcopenia) AND (randomized). The “Interventional” filter was selected. The inclusion criteria for this review were: (1) randomized controlled trial, (2) ongoing or completed but not yet published, (3) population of older adults with frailty/pre-frailty or sarcopenia as determined by an objective assessment tool (broadly defined as a multi-item frailty scale such as Fried’s,5 low
Results
The search identified 265 entries, of which 20 met the inclusion criteria for this review (Table 1, Fig 2). The official status was not yet recruiting in 5 RCTs, recruiting in 6, active but not recruiting in 4, and completed but not yet published in 5. The frailty criteria used to determine eligibility were PPTs in 8 RCTs, Fried’s scale in 6, muscle mass with or without PPTs in 3, and other scales in 3. Five RCTs focused on individuals with a specific comorbidity: stable coronary artery
Discussion
One half of registered RCTs are evaluating exercise and/or nutrition, which have long been recognized as therapeutic cornerstones for frailty. These RCTs are all short-term in design, ranging from 3 to 6 months, and it remains to be seen whether this is sufficient time to reverse existing frailty and yield clinically detectable benefits. Regular exercise and physical activity have been shown to prevent or delay incident frailty.7 Two systematic reviews including frail and non-frail older adults
