Gerofit Prehabilitation Pilot Program: Preparing Frail Older Veterans for Surgery

Older Veterans' perspectives on participation in a clinical exercise program: A qualitative study of the VA Gerofit exercise program

Objectives

We explored the perspectives of older veterans in Gerofit, a Department of Veteran Affairs (VA) supervised clinical exercise program, to understand the factors associated with participation and how the program supported personal health goals.

Methods

Twenty semistructured interviews were conducted with active and inactive Gerofit participants. We used a hybrid inductive and deductive approach to thematic analysis of transcripts, with the latter informed by the Health Action Process Approach model of behavior change.

Results

Active and inactive participants differed in their perspectives about how Gerofit impacted their progress toward meeting personal health goals. Active participants noted program features (e.g., schedule, staffing) as facilitators and suggested greater self-efficacy about program participation compared to inactive participants. Both groups perceived the camaraderie with other veterans as a facilitator.

Conclusions

Exercise program features, including camaraderie, are important factors that affect the ability of older veterans to participate in exercise and achieve personal health goals.

Outcomes and risk factors for delayed-onset postoperative respiratory failure: a multi-center case-control study by the University of California Critical Care Research Collaborative (UC3RC)

BACKGROUND

Few interventions are known to reduce the incidence of respiratory failure that occurs following elective surgery (postoperative respiratory failure; PRF). We previously reported risk factors associated with PRF that occurs within the first 5 days after elective surgery (early PRF; E-PRF); however, PRF that occurs six or more days after elective surgery (late PRF; L-PRF) likely represents a different entity. We hypothesized that L-PRF would be associated with worse outcomes and different risk factors than E-PRF.

METHODS

This was a retrospective matched case-control study of 59,073 consecutive adult patients admitted for elective non-cardiac and non-pulmonary surgical procedures at one of five University of California academic medical centers between October 2012 and September 2015. We identified patients with L-PRF, confirmed by surgeon and intensivist subject matter expert review, and matched them 1:1 to patients who did not develop PRF (No-PRF) based on hospital, age, and surgical procedure. We then analyzed risk factors and outcomes associated with L-PRF compared to E-PRF and No-PRF.

RESULTS

Among 95 patients with L-PRF, 50.5% were female, 71.6% white, 27.4% Hispanic, and 53.7% Medicare recipients; the median age was 63 years (IQR 56, 70). Compared to 95 matched patients with No-PRF and 319 patients who developed E-PRF, L-PRF was associated with higher morbidity and mortality, longer hospital and intensive care unit length of stay, and increased costs. Compared to No-PRF, factors associated with L-PRF included: preexisiting neurologic disease (OR 4.36, 95% CI 1.81-10.46), anesthesia duration per hour (OR 1.22, 95% CI 1.04-1.44), and maximum intraoperative peak inspiratory pressure per cm H₂0 (OR 1.14, 95% CI 1.06-1.22).

CONCLUSIONS

We identified that pre-existing neurologic disease, longer duration of anesthesia, and greater maximum intraoperative peak inspiratory pressures were associated with respiratory failure that developed six or more days after elective surgery in adult patients (L-PRF). Interventions targeting these factors may be worthy of future evaluation.

Enhanced Recovery after Surgery: Perspective in Elder Women

Enhanced recovery after surgery (ERAS) is a multimodal convention first reported for colorectal and gynecologic procedures. The main benefits have been a shorter length of stay and reduced complications, leading to improved clinical outcomes and cost savings substantially. With increase in life expectancy, recent years has shown a significant rise in advanced age population, and similarly, a rise in age-related disorders requiring surgical management. Due to pathophysiological and metabolic changes in geriatric age group with increased incidence of medical comorbidities, there is higher risk of enhanced surgical stress response with undesirable postoperative morbidity, complications, prolonged immobility, and extended convalescence. The feasibility and effectiveness of ERAS protocols have been well researched and documented among all age groups, including the geriatric high-risk population.^[1] Adhering to ERAS protocols after colorectal surgery showed no significant difference in postoperative complications, hospital stay, or readmission rate among various age groups.^[2] A recent report mentions the safety and benefits following ERAS guidelines with reduced length of stay in elderly patients with short-level lumbar fusion surgery.^[3] The concept of prehabilitation has evolved as an integral part of ERAS to build up physiological reserve, especially in geriatric high-risk group, and to adapt better to surgical stress.^[4] High levels of compliance with ERAS interventions combined with prehabilitation can be achieved when a dedicated multidisciplinary team is involved in care of these high-risk patients.
