Cardiac Enhanced Recovery After Surgery: Early Outcomes in a Community Setting

Effect of Enhanced Recovery After Surgery (ERAS) Programs on Perioperative Outcomes in Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-analysis

BACKGROUND

Enhanced recovery after surgery (ERAS) programs emerged as a strategy to reduce perioperative morbidity; however, there is currently limited evidence of their clinical efficacy. The objective of this study was to assess the impact of ERAS programs in cardiac surgery on hospital length of stay, mortality, atrial fibrillation, and quality of life.

METHODS

A systematic review and meta-analysis were conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement, encompassing studies on ERAS programs in adult patients undergoing elective cardiac surgery. The effect size and 95% confidence interval (CI) were estimated with a random-effects model. The protocol was preregistered on Open Science Framework.

RESULTS

Eighteen studies (published between 2016 and 2023) comprising 4,469 patients were included in the analysis, of which only one was a randomized controlled trial. The implementation of ERAS was associated with a reduction in hospital stay of 1.24 days (95% CI: -1.67, -0.82, p < 0.001, I2 = 83%). No differences were observed between the groups in mortality (odds ratio: 0.65, 95% CI: 0.28, 1.48, p = 0.3, I2 = 0%), nor in the incidence of atrial fibrillation (odds ratio: 0.77, 95% CI: 0.57, 1.03, p = 0.08, I2 = 17%). A meta-analysis of quality of life was not feasible due to a lack of sufficient data.

CONCLUSIONS

Although ERAS programs were associated with a reduction in hospital stay and no differences in mortality or atrial fibrillation, the quality of the evidence was very low. To recommend the implementation of ERAS programs in cardiac surgery, it is necessary to have randomized studies providing evidence of its efficacy, and studies including quality of life and other patient-centered recovery criteria outcomes.

Multimodal analgesia with parasternal plane block protocol within an enhanced recovery after cardiac surgery program decreases opioid use

Objective

This study investigated the efficacy of a multimodal analgesia (MMA) with an opioid-sparing strategy, incorporating a parasternal plane block (PPB) within a systematic standardized Enhanced Recovery After Surgery (ERAS) program for patients undergoing elective cardiac surgery.

Methods

From 2015 to 2021, 3153 patients underwent elective coronary artery bypass grafting and/or valve procedures. Patients were dichotomized by the presence or absence of an ERAS program including a perioperative MMA with an opioid-sparing approach and PPB protocols. Propensity score matching yielded 1026 well-matched pairs. The primary outcomes were the opioid-free rate and the opioid consumption in morphine milligram equivalents (MME) in the intensive care unit (ICU). The secondary outcomes were postoperative visual analog scale (VAS) scores, mechanical ventilation duration, ileus, delirium, bronchopneumonia, and length of ICU stay.

Results

The ICU opioid-free rate was significantly increased in the ERAS group (94.0%) compared with the control group (19.9%; P < .001). The ERAS group had significantly lower opioid consumption in the ICU compared with the control group (median; 11.0 MME vs 31.0 MME; P < .001; respectively). The VAS scores were analogous between the control and ERAS groups during the ICU stay. In the ERAS group, mechanical ventilation duration, ileus, delirium, bronchopneumonia rates, as well as length of ICU stay, were significantly reduced (both P < .05).

Conclusions

Within a systematic, standardized ERAS program, MMA with an opioid-sparing strategy and PPB enables opioid-free analgesia in the majority of patients, significantly decreases opioid consumption, and ensures effective postoperative pain management, thereby improving outcomes.

Rigid Sternal Fixation and Enhanced Recovery for Opioid-Free Analgesia After Cardiac Surgery

BACKGROUND

We evaluated the individual contributions of rigid-plate fixation (RPF) and an enhanced recovery protocol (ERP) on postoperative pain, opioid use, and other outcomes after median sternotomy as they were sequentially adopted into practice.

METHODS

This single-center, retrospective, case-cohort study compared outcomes between median sternotomy patients (all comers) who underwent operation before implementation of RPF or ERP ("controls"), patients closed with RPF before ERP implementation ("RPF-only"), and patients managed with RPF and ERP during early "RPF+ERP-2020" and late "RPF+ERP-2022" implementation.

RESULTS

The analysis included 608 median sternotomy patients (mean age, 65.7 ± 10.8 years; 29.6% women). Of those, 59.2% were isolated coronary artery bypass grafting, 7.7% were isolated valve procedures, and the rest were mixed/concomitant procedures. Median in-hospital, postoperative opioid administration was 172.5 morphine milligram equivalents (MMEs) in the control cohort vs 0 MMEs for RPF+ERP-2022 (P < .0001), despite similar or slightly reduced patient-reported pain scores. The proportion of patients discharged directly to home was 66.2% for controls, 79.6% for RPF-only (P = .010), and 93.5% for RPF+ERP-2022 (P < .0001). Median opioids prescribed at discharge were 600 MMEs for controls and 0 for RPF+ERP-2020 and RPF+ERP-2022 (P < .0001). At discharge, 86.7% of RPF-only patients received prescription opioids vs 5% in RPF+ERP-2020 and 4.3% RPF+ERP-2022 (P < .0001). These outcomes occurred without increased readmissions.

CONCLUSIONS

Systematic implementation of RPF and ERP was associated with a significant and clinically meaningful decrease in opioid use in this large, real-world patient population.

Enhanced recovery after surgery program for patients undergoing isolated elective coronary artery bypass surgery improves postoperative outcomes

OBJECTIVE

To evaluate the effect of a perioperative systematic standardized enhanced recovery after surgery (ERAS) program for patients undergoing isolated elective coronary artery bypass grafting (CABG) in terms of mortality, hospital morbidities, and length of stay.

METHODS

From January 2015 to September 2020, 1101 patients underwent isolated elective CABG. Our standardized systematic ERAS program was implemented in November 2018. Propensity score matching resulted in well-matched pairs of 362 patients receiving standard perioperative care (control group) and 362 patients on the ERAS program (ERAS group). There were no significant intergroup differences in preoperative and operative data except for the normothermia rate, which was significantly greater in the ERAS group (P < .001). The primary outcome was 3-year mortality. The secondary outcomes were hospital morbidities and length of stay.

RESULTS

In-hospital and 3-year mortality did not differ between the 2 groups. The ERAS program was associated with a significant relative risk decrease in mechanical ventilation duration (-53.1%, P = .003), length of intensive care unit stay (-28.0%, P = .015), length of hospital stay (-10.5%, P = .046), bronchopneumonia (-51.5%, P < .001), acute respiratory distress syndrome (-50.8%, P = .050), postoperative delirium (-65.4%, P = .011), moderate-to-severe acute kidney injury (-72.0%, P = .009), 24-hour chest tube output (-26.4%, P < .001), and overall red blood cell transfusion rate (-32.4%, P = .005) compared with the control group.

CONCLUSIONS

A systematic standardized ERAS program for low-risk patients undergoing isolated elective CABG was associated with a significant improvement in postoperative outcomes, reduction in red blood cell transfusion, shorter lengths of intensive care unit and hospital stays, and comparable long-term mortality.

Maximizing Minimally Invasive Cardiac Surgery With Enhanced Recovery (ERAS)

We convened a group of cardiac surgeons, intensivists, and anesthesiologists with extensive experience in minimally invasive cardiac surgery (MICS) and perioperative care to identify the essential elements of a MICS program and the relationship with Enhanced Recovery After Surgery (ERAS). The MICS incision should minimize tissue invasion without compromising surgical goals. MICS also requires safe management of hemodynamics and preservation of cardiac function, which we have termed myocardial management. Finally, comprehensive perioperative care through an ERAS program should be provided to allow patients to achieve optimal recovery. Therefore, we propose that MICS requires 3 elements: (1) a less invasive surgical incision (non-full sternotomy), (2) optimized myocardial management, and (3) ERAS. We contend that the full benefit of MICS can be achieved only by also utilizing an ERAS platform.

Implementing an evidence-based guideline to decrease opioids after cardiac surgery

BACKGROUND

Deaths related to overdoses continue growing in the United States. The overprescription of opioids after surgical procedures may contribute to this problem.

LOCAL PROBLEM

There is inconsistency in the prescription of opioids in cardiovascular surgery patients. Recommendations regarding the reduction of opioids at discharge are not fully implemented.

METHODS

This is a single-center, pre-post quality improvement project in adult patients after elective cardiac surgery through sternotomy.

INTERVENTIONS

Changes in guidelines, modification of order sets, creation of dashboards, and education to the providers to increase the prescription of acetaminophen around the clock on the step-down unit and at discharge, decrease the number of opioid tablets to 25 or less at discharge and decrease the prescription of opioids to 25 or less morphine milligram equivalents (MME) at discharge.

RESULTS

The preintervention group included 67 consecutive patients who underwent cardiac surgery from November to December 2021. The postintervention group had 67 patients during the same period in 2022. Acetaminophen prescription on the step-down unit increased from 9% to 96% ( p < .001). The proportion of patients discharged with 25 or less opioid tablets increased from 18% to 90% ( p < .001) and with 25 or less MME from 30% to 55% ( p < .01). Acetaminophen prescription at discharge increased from 10% to 48% ( p < .001).

CONCLUSIONS

Our intervention increased the use of acetaminophen and decreased the overprescription of opioids in cardiac surgery patients at discharge. Further research is necessary to continue improving pain management to reduce the number of opioids prescribed at discharge.

Exploring perioperative risk factors for poor recovery of postoperative gastrointestinal function following gynecological surgery: A retrospective cohort study

Purpose

To investigate perioperative risk factors that affect the recovery of postoperative gastrointestinal function in patients undergoing gynecological surgery and to establish a preoperative risk prediction scoring system.

Methods

In this retrospective cohort study, characteristics and perioperative factors of patients who underwent elective gynecological surgery at Union Hospital from January 2021 to March 2022 were extracted from electronic medical records. Patients were grouped according to the Intake, Feeling nauseated, Emesis, physical Exam, and Duration of symptoms (I-FEED) scoring system to compare collected data.

Results

In total, clinical data from 208 gynecological patients were extracted. The incidence of poor postoperative gastrointestinal recovery was 7.21 %. The number of previous abdominal surgeries (0.73 ± 0.06 vs 1.20 ± 0.24, p = 0.044), the incidence of malignant disease (20.2 % vs 53.3 %, p = 0.003), postoperative maximum WBC count (9.15 vs 12.44, p = 0.005) and postoperative minimum potassium (3.97 ± 0.36 vs 3.76 ± 0.37, p = 0.036) were not only associated with poor postoperative gastrointestinal recovery, but also malignant disease (p = 0.000), postoperative maximum WBC count (p = 0.027) and postoperative minimum potassium (p = 0.024) were significantly associated with the severity of postoperative gastrointestinal function. An increased number of previous abdominal surgeries and malignant primary disease could increase the risk of an I-FEED score >2 as independent risk factors.

Conclusion

Patients with poor postoperative GI function had poorer postoperative recovery outcomes. A preoperative score prediction system was established, in which patients with ≥2 points had a 19.4 % risk of poor postoperative gastrointestinal recovery. Higher-quality prospective studies should be performed to achieve more precise risk stratification and to construct a more accurate prediction system.
