Frailty is a syndrome characterized by decreased reserve and diminished resistance to stressors. The proposed research will evaluate the association of frailty with chronic kidney disease (CKD). The prevalence of frailty increases with age and with CKD, but studies are needed to determine whether frailty is associated with worsening of CKD and whether intervention to treat frailty can improve physical functioning and health-related quality of life (HRQOL) as well as slow progression of CKD.
The intervention is a 6-month prospective interventional pilot study targeted to each domain of frailty. Subjects will be screened into the study by testing each domain; only those who meet criteria for frailty will be included in the study. The clinical intervention, which all subjects will receive, will begin immediately upon enrollment and completion of baseline measurements. Upon enrollment the 3 most recent previous outpatient serum creatinine measurements (up to 1 year) will be used to determine baseline slope of estimated glomerular filtration rate (eGFR). The main objectives of the pilot study will be to gain knowledge in the successful implementation and completion of an intervention targeted toward frailty. Ultimately information ascertained from this pilot will serve as a springboard for planning of a randomized trial aimed at addressing all the domains of frailty, which is key given that previous studies have only implemented interventions aimed at a single domain or in pairs, but no studies have evaluated the extent to which frailty can be reversed through a cohesive intervention addressing all domains together. The intervention outlined in this proposal is comprehensive and focused while maintaining feasibility.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Not frail | No Intervention | Source of these participants will be the same as those who screen into the study; patients with chronic kidney disease receiving care at the San Francisco Veteran Affairs Medical Center. Based on initial screening if participants do not meet criteria for frailty, baseline screening data will be used for comparative analysis as the no intervention arm. | |
| Frail | Experimental | Source of these participants will be the same as those who screen into the study; patients with chronic kidney disease receiving care at the San Francisco Veteran Affairs Medical Center. Based on initial screening if participants meet criteria for frailty participants will be enrolled in the intervention arm. Participants who are ambulatory regardless of co-morbidities will not be excluded from the study. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Frail | Behavioral | Slowness/weakness: Physical therapy(PT) strength and gait training. A standardized strengthening program will be prescribed, to be performed at home. Additional in-person PT training will be provided to those who are severely deconditioned . Weight loss/malnutrition: A licensed nutritionist specializing in kidney disease will meet with participants for 3 one-hour one-on-one nutritional counseling. Low physical activity: Participants will receive individualized walking recommendations using a pedometer. Walking activity will be assessed weekly, and new goals for increasing steps in the following week will be set. Exhaustion: Those who meet criteria for severe depression using the center for epidemiologic studies depression (CES-D) scale will be immediately referred to psychiatry for counseling for patient safety. All others will participate in cognitive behavioral coping techniques. |
| Measure | Description | Time Frame |
|---|---|---|
| Pedometer Step Count | The number of steps achieved over the 6 month period will be assessed. Pedometer data is collected each week. Based on the weekly achieved counts a new goal is generated for each participant. This assessment will include study investigators collecting step count logs from the participant on a weekly basis. | Change from baseline step count to 6 months |
| Physical Function | Change in physical functioning will be assessed using the short physical performance battery (SPPB). Investigators will compare baseline Short physical performance battery (SPPB) score to 6 month score to determine change in functioning as a result of the intervention. | baseline and 6 months |
