Effect of prehabilitation-related DIETary protein intake on Quality of Recovery after elective cardiac surgery (DIETQoR) study: protocol of a randomised controlled trial

The Malnutrition Universal Screening Tool (MUST) Predicts Postoperative Declines in Activities of Daily Living (ADL) in Patients Undergoing Cardiovascular Open-Heart Surgery

Background: Patients undergoing cardiovascular surgery often experience postoperative complications and Activities of Daily Living (ADL) decline, even in the absence of preoperative malnutrition. Since postoperative ADL decline is particularly serious in elderly patients, this study aimed to identify a nutritional assessment tool that is effective in predicting postoperative ADL decline. Methods: Patients undergoing open-heart surgery with cardiopulmonary bypass were assessed using eight nutritional assessment tools, including the Malnutrition Universal Screening Tool (MUST), the Global Leadership Initiative on Malnutrition (GLIM) criteria, the Nutritional Risk Screening 2002 (NRS-2002), the Subjective Global Assessment (SGA), the Controlling Nutritional Status (CONUT) score, the Prognostic Nutritional Index (PNI), the Geriatric Nutritional Risk Index (GNRI), and the Mini Nutritional Assessment-Short Form (MNA-SF). Results: A total of 197 patients were enrolled in this study, with a mean age of 70.4 ± 11.6 years old; 31.0% were female. Depending on the nutritional assessment tool, 17.8% to 78.2% of patients were identified as at risk of malnutrition. Among the various assessment tools, the MUST was the most effective in predicting postoperative ADL decline (OR 4.75, 95% CI 1.37-16.5, p = 0.014) and was also associated with severe complications and length of hospital stay (OR 3.08, 95% CI 0.20-0.76, p = 0.009). On the other hand, nutritional risk detected by assessment tools other than MUST, including MNA-SF and GLIM, could predict postoperative complications but showed no relationship to ADL decline. Conclusions: We concluded that MUST was the most useful preoperative nutritional assessment tool for predicting outcomes, particularly for assessing the risk of postoperative ADL decline in patients undergoing cardiovascular surgery.

Effect of exercise prehabilitation on quality of recovery after cardiac surgery: a single-centre randomised controlled trial

BACKGROUND

Physical prehabilitation can enhance patient resilience to surgical stress, but its effects are unclear in vulnerable and frail patients. We aimed to determine the effect of a structured exercise prehabilitation programme on the quality of recovery after cardiac surgery in vulnerable and frail participants.

METHODS

This single-blinded, parallel-arm, superiority, randomised controlled trial recruited patients with a Clinical Frailty Scale of 4-6 undergoing cardiac surgery. Patients were randomised to either physical prehabilitation (twice weekly) or standard care (control); both arms received standard perioperative care. The primary outcome was Quality of Recovery-15 (QoR-15) score on the third day after surgery. Secondary outcomes included major adverse cardiac and cerebrovascular events (MACCE), days alive and at home (DAH30), and the World Health Organization Disability Assessment Schedule (WHODAS) 2.0 metric.

RESULTS

Of 164 randomised patients, 138 were included in the primary analysis (median age 64 [interquartile range 60-69] yr; 70% males). Compliance with the 5-week prehabilitation programme was high (82%), with no adverse exercise-induced events reported. There were no between-group differences in QoR-15 scores (median difference -3, 95% confidence interval [CI] -9 to 3), early and late MACCE, and DAH30 (P=0.779). Prehabilitated patients had lower disability levels than control patients (P=0.022) at 90 days after surgery (mean difference -9%, 95% CI -17% to -2%).

CONCLUSIONS

A 5-week programme of physical prehabilitation in predominately prefrail patients was safe, but it did not enhance quality of recovery scores after surgery. Prehabilitation resulted in a clinically meaningful decrease in disability scores at 90 days after surgery.

The effect of pre-habilitation programs on surgical outcomes among patients undergoing elective cardiac surgery

Pre-habilitation programs, designed to optimize physical, nutritional and psychological health before surgery, show promise in improving outcomes for elective cardiac surgery. This randomized controlled trial assessed the impact of a 4-week prehabilitation program on 100 patients undergoing elective cardiac surgery, comparing it to standard preoperative care. The prehabilitation group experienced significantly fewer postoperative complications (12% vs. 28%, p = 0.016), shorter hospital stays (6.4 ± 1.8 days vs. 8.2 ± 2.1 days, p < 0.001) and improved 30-day functional recovery (p = 0.005). These findings demonstrate that prehabilitation enhances recovery, reduces complications and shortens hospitalization, supporting its inclusion in preoperative protocols for elective cardiac surgery.

Start Strong, Finish Strong: A Review of Prehabilitation in Cardiac Surgery

Cardiac surgery constitutes a significant surgical insult in a patient population that is often marred by significant comorbidities, including frailty and reduced physiological reserve. Prehabilitation programs seek to improve patient outcomes and recovery from surgery by implementing a number of preoperative optimization initiatives. Since the initial trial of cardiac prehabilitation twenty-four years ago, new data have emerged on how to best utilize this tool for the perioperative care of patients undergoing cardiac surgery. This review will explore recent cardiac prehabilitation investigations, provide clinical considerations for an effective cardiac prehabilitation program, and create a framework for future research studies.

Temporary mechanical circulatory support & enhancing recovery after cardiac surgery

PURPOSE OF REVIEW

This review highlights the integration of enhanced recovery principles with temporary mechanical circulatory support associated with adult cardiac surgery.

RECENT FINDINGS

Enhanced recovery elements and efforts have been associated with improvements in quality and value. Temporary mechanical circulatory support technologies have been successfully employed, improved, and the value of their proactive use to maintain hemodynamic goals and preserve long-term myocardial function is accruing.

SUMMARY

Temporary mechanical circulatory support devices promise to enhance recovery by mitigating the risk of complications, such as postcardiotomy cardiogenic shock, organ dysfunction, and death, associated with adult cardiac surgery.
