Summary

The purpose of this pilot study is to evaluate a high intensity walking intervention in older surgical candidates with kidney or thoracic disease and pre-frailty or frailty.

Detailed description

As the population ages, there are an increasing number of older adults presenting for surgical evaluation. Frailty evaluation has been recognized as a valuable tool in the pre-operative assessment of older adults. Frailty is a clinical syndrome with multiple causes and contributors that involves poor regulation of multiple physiologic systems and is characterized by reduced strength, endurance, and physiologic function. Frailty is a predictor of poor surgical outcomes in older patients, including post-operative complications, increased length of stay, post-discharge institutionalization, and mortality.Identification of frailty in the pre-operative period can aid in risk assessment and decision making for the procedure, can help inform a plan for post-operative care needs, and may provide a target for pre-operative risk reduction interventions. Given the association of frailty with poor surgical outcomes and the high prevalence of frailty in surgical candidates, there has been much interest in interventions to mitigate this risk. Exercise interventions in other populations have shown success, although the optimal interventions are unknown. In both thoracic surgery and kidney transplantation, there may be a limited amount of time for intervention prior to the operation and patients often have other commitments, such as frequent medical appointments or dialysis sessions. Thus, a short duration program may be beneficial for these populations. High intensity walking is an approach that has shown to lead to functional gains in as short as 12 sessions. The therapists can also modify a high intensity walking program as needed for patients based on physical limitations, making it widely applicable for frail older adults of varying physical function levels, which is important to our older surgical populations. Surgical patients, which include kidney transplant and thoracic surgery patients, are particularly well suited to a pilot high intensity walking intervention given the high proportion of frailty and pre-frailty in these groups. In this study, the investigator will examine a 12-week high intensity walking program for frail older surgical candidates.

Interventions

Type	Name	Description
BEHAVIORAL	High Intensity Walking	Participants will then undergo a 12 session intervention, with two sessions scheduled per week for six weeks. These will be 45 minute sessions, including 15 minutes of a warm-up and cool-down period as well as 30 minutes of walking. The intervention will include various types of over ground walking and stair work.
