Abstract
BACKGROUND Good preoperative conditions help patients to counteract surgical injury. Prehabilitation is a multimodal preoperative management strategy, including physical, nutritional, psychological, and other interventions, which can improve the functional reserve of patients and enhance postoperative recovery. The purpose of this study is to show the evolution trend and future directions of research related to the prehabilitation of surgical patients. METHODS The global literature regarding prehabilitation was identified from The Web of Science Core Collection database. Bibliometric methods of the Bibliometrix package of R (version 4.2.1) and VOSviewer were used to analyze publication trends, cooperative networks, study themes, and co-citation relationships in the field. RESULTS A total of 638 publications were included and the number of publications increased rapidly since 2016, with an average annual growth rate of 41.0%. "Annals of Surgery", "British Journal of Surgery" and "British Journal of Anesthesia" were the most cited journals. Experts from the USA, Canada, the UK, and the Netherlands contributed the most in this field, and an initial cooperative network among different countries and clinical teams was formed. Malnutrition, older patients, frailty, and high-risk patients were the hotspots of recent studies. However, among the top 10 cited articles, the clinical effects of prehabilitation were conflicting. CONCLUSION This bibliometric review summarized the most influential publications as well as the publication trends and clarified the progress and future directions of prehabilitation, which could serve as a guide for developing evidence-based practices.

Association between improved compliance with enhanced recovery after cardiac surgery guidelines and postoperative outcomes: A retrospective study. J Thorac Cardiovasc Surg 2024; 167:1363-1371.e2. [PMID: 35989120 DOI: 10.1016/j.jtcvs.2022.07.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 06/23/2022] [Accepted: 07/06/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Enhanced recovery after cardiac surgery is a multidisciplinary clinical care pathway that relies on a bundle of interventions, aiming to reduce the stress response to surgery and promote early recovery of organ function. In 2011, our institution introduced an institutional enhanced recovery after cardiac surgery program focusing on 9 central interventions, which have been expanded during the past decade by additional interventions now considered standard of care. After the recent publication of the enhanced recovery after cardiac surgery guidelines, we evaluated the relation between the compliance with these enhanced recovery after cardiac surgery guidelines and postoperative outcomes. METHODS All patients enrolled in our enhanced recovery after cardiac surgery program in 2019 were included in this retrospective single-center audit. The primary outcome was compliance with 23 enhanced recovery after cardiac surgery guidelines. Secondary outcomes included occurrence of at least 1 postoperative complication and hospital length of stay. RESULTS A total of 356 patients were included in this study. Compliance with the enhanced recovery after cardiac surgery guidelines was 64%. Postoperatively, 51% of the patients experienced at least 1 complication and had a median hospital length of stay of 6 days. Multivariable analysis showed that an increased compliance (per 10%) with the enhanced recovery after cardiac surgery guidelines was associated with a lower risk for any complication (odds ratio, 0.60; 95% confidence interval, 0.46-0.79; P = .0003) and a higher probability of earlier hospital discharge (hazard ratio, 1.25; 95% confidence interval, 1.10-1.43; P = .0008). CONCLUSIONS This audit revealed a correlation between increased compliance with enhanced recovery after cardiac surgery guidelines and a reduction of postoperative complications and hospital length of stay. Future trials are needed to establish evidence-based recommendations for each separate intervention of the enhanced recovery after cardiac surgery guidelines and to create a minimum core-set of enhanced recovery after cardiac surgery interventions.

Abstract
Enhanced recovery after surgery (ERAS) is a multimodal perioperative management concept, but there is no article to comprehensively review the collaboration and impact of countries, institutions, authors, journals, references, and keywords on ERAS from a bibliometric perspective. This study assessed the evolution of clustering of knowledge structures and identified hot trends and emerging topics. Articles and reviews related to ERAS were retrieved through subject search from the Web of Science Core Collection. We used the following strategy: "TS = Enhanced recovery after surgery" OR "Enhanced Postsurgical Recovery" OR "Postsurgical Recoveries, Enhanced" OR "Postsurgical Recovery, Enhanced" OR "Recovery, Enhanced Postsurgical" OR "Fast track surgery" OR "improve surgical outcome". Bibliometric analyses were conducted on Excel 365, CiteSpace, VOSviewer, and Bibliometrics (R-Tool of R-Studio). Totally 3242 articles and reviews from 1997 to 2022 were included. These publications were mainly from 684 journals in 78 countries, led by the United States and China. Kehlet H published the most papers and had the largest number of co-citations. Analysis of the journals with the most outputs showed that most journals mainly cover Surgery and Oncology. The hottest keyword is "enhanced recovery after surgery". Later appearing topics and keywords indicate that the hotspots and future research trends include ERAS protocols for other types of surgery and improving perioperative status, including "bariatric surgery", "thoracic surgery", and "prehabilitation". This study reviewed the research on ERAS using bibliometric and visualization methods, which can help scholars better understand the dynamic evolution of ERAS and provide directions for future research.

Abstract
Perioperative neurocognitive disorders are common and concerning complications in older adults undergoing surgery that can manifest as acute or chronic cognitive decline. It is hypothesized that cognitive prehabilitation can prepare the brain for the stress of surgery as for any other organ system. In this mini review we discuss the rationale for using cognitive prehabilitation, some of the interventions that have been assessed, and the effects of these interventions on postoperative cognition. PATIENT SUMMARY: Training the brain before surgery can potentially reduce the risk of cognitive decline after surgery in older adults. This mini review discusses some of the trials that examined how to train the brain before surgery and the results from these trials.

Abstract
(1) Background and aim: This study aimed to investigate the impact of prehabilitation on the postoperative outcomes of heart transplantation and its cost-effectiveness. (2) Methods: This single-center, ambispective cohort study included forty-six candidates for elective heart transplantation from 2017 to 2021 attending a multimodal prehabilitation program consisting of supervised exercise training, physical activity promotion, nutritional optimization, and psychological support. The postoperative course was compared to a control cohort consisting of patients transplanted from 2014 to 2017 and those contemporaneously not involved in prehabilitation. (3) Results: A significant improvement was observed in preoperative functional capacity (endurance time 281 vs. 728 s, p < 0.001) and quality-of-life (Minnesota score 58 vs. 47, p = 0.046) after the program. No exercise-related events were registered. The prehabilitation cohort showed a lower rate and severity of postoperative complications (comprehensive complication index 37 vs. 31, p = 0.033), lower mechanical ventilation time (37 vs. 20 h, p = 0.032), ICU stay (7 vs. 5 days, p = 0.01), total hospitalization stay (23 vs. 18 days, p = 0.008) and less need for transfer to nursing/rehabilitation facilities after hospital discharge (31% vs. 3%, p = 0.009). A cost-consequence analysis showed that prehabilitation did not increase the total surgical process costs. (4) Conclusions: Multimodal prehabilitation before heart transplantation has benefits on short-term postoperative outcomes potentially attributable to enhancement of physical status, without cost-increasing.

Abstract
Transplanted patients could benefit from complementary techniques. This prospective single-center, open study, performed in a tertiary university hospital, evaluates the appropriation and efficacy of a toolbox-kit of complementary techniques. Self-hypnosis, sophrology, relaxation, holistic gymnastics, and transcutaneous electric nerve stimulation (TENS) were taught to adult patients scheduled for double-lung transplantation. Patients were asked to use them before and after transplantation, as needed. The primary outcome was appropriation of each technique within the first three postoperative months. Secondary outcomes included efficacy on pain, anxiety, stress, sleep, and quality-of-life. Among the 80 patients included from May 2017 to September 2020, 59 were evaluated at the 4th postoperative month. Over the 4359 sessions performed, the most frequent technique used before surgery was relaxation. After transplantation, the techniques most frequently used were relaxation and TENS. TENS was the best technique in terms of autonomy, usability, adaptation, and compliance. Self-appropriation of relaxation was the easiest, while self-appropriation of holistic gymnastics was difficult but appreciated by patients. In conclusion: the appropriation by patients of complementary therapies such as mind-body therapies, TENS and holistic gymnastics is feasible in lung transplantation. Even after a short training session, patients regularly practiced these therapies, mainly TENS and relaxation.

Abstract
Perioperative optimization of cardiac surgical patients is imperative to reduce complications, utilize health care resources efficiently, and improve patient recovery and quality of life. Standardized application of evidence-based best practices can lead to better outcomes. Although many practices should be applied universally to all patients, there are also opportunities along the surgical journey to identify patients who will benefit from additional interventions that will further ameliorate their recovery. Enhanced recovery programs aim to bundle several process elements in a standardized fashion to optimize outcomes after cardiac surgery. A foundational concept of enhanced recovery is attaining a better postsurgical end point for patients, in less time, through achievement and maintenance in their greatest possible physiologic, functional, and psychological state. Perioperative optimization is a broad topic, spanning multiple phases of care and involving a variety of medical specialties and nonphysician health care providers. In this review we highlight a variety of perioperative care topics, in which a comprehensive approach to patient care can lead to improved results for patients, providers, and the health care system. A particular focus on patient-centred care is included. Although existing evidence supports all of the elements reviewed, most require further improvements in implementation, as well as additional research, before their full potential and usefulness can be determined.

The role of prehabilitation on short-term outcomes after liver transplantation: A review of the literature and expert panel recommendations. Clin Transplant 2022; 36:e14686.

Abstract
BACKGROUND Prehabilitation programs as part of ERAS protocols are being increasingly used in multiple surgeries, improving postoperative outcomes. Data regarding prehabilitation programs in patients awaiting liver transplantation and their outcomes is scarce. OBJECTIVES To identify whether prehabilitation programs based on exercise training conducted prior to liver transplantation improve short-term postoperative outcomes, and to provide expert panel recommendations. DATA SOURCES Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. Studies included those evaluating postoperative outcomes, as well as those evaluating functional outcomes. PROSPERO ID CRD42021236305. RESULTS Of the 170 studies screened, only one assessed the primary objective. Most studies focus on the preoperative impact of exercise training on aerobic capacity, muscle mass and/or strength, showing positive effects and no significant adverse events, but are underpowered and with heterogenous designs and interventions. The non-randomized observational study which assessed relevant postoperative outcomes, showed a non-significant trend towards reduced 90-day readmission rate and shorter length of stay in the prehabilitation group. CONCLUSIONS Prehabilitation prior to liver transplantation is unlikely to be harmful, and likely to have short term benefits on functional status. We cautiously recommend prehabilitation on the basis of absence of harm and possibility of benefit (Quality of Evidence; Very Low | Grade of Recommendation; Low).

[PMID: 35743505 PMCID: PMC9225521 DOI: 10.3390/jcm11123435] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/09/2022] [Accepted: 06/12/2022] [Indexed: 02/01/2023] Open
Abstract
Enhanced recovery after surgery (ERAS) protocols are designed to reduce medical complications, the length of hospital stays (LoS), and healthcare costs. ERAS is considered safe and effective for kidney transplant (KTx) surgery. KTx recipients are often frail with multiple comorbidities. As these patients follow an extensive diagnostic pathway preoperatively, the ERAS protocol can ideally be implemented at this stage. Small singular changes in a long perioperative pathway can result in significant positive outcomes. We have investigated the current evidence for an ERAS pathway related to anaesthetic considerations in renal transplant surgery for adult recipients.

Abstract
Cancer and surgery represent a major stress on the human body. Any condition that prevents patients from tolerating the physiological stress is a risk factor for poor outcome. There is a need to identify these impairments early in the process with a simple screening, followed by assessments that provide a holistic picture of the patient. The proposed path of multimodal prehabilitation acts synergistically with enhanced recovery after surgery care to achieve optimal patient outcomes.

Abstract
Abstract
Purpose
This article focuses on the following:
The importance of prehabilitation in people with cancer and the known and hypothesised benefits.
Exploration of the principles that can be used when developing services in the absence of a single accepted model of how these services could be established or configured.
Description of approaches and learning in the development and implementation of prehabilitation across three different countries: Canada, the Netherlands and the United Kingdom, based on the authors’ experiences and perspectives.
Recent Findings
Practical tips and suggestions are shared by the authors to assist others when implementing prehabilitation programmes. These include experience from three different approaches with similar lessons.
Important elements include the following: (i) starting with a small identified clinical group of patients to refine and test the delivery model and demonstrate proof of concept; (ii) systematic data collection with clearly identified target outcomes from the outset; (iii) collaboration with a wide range of stakeholders including those who will be designing, developing, delivering, funding and using the prehabilitation services; (iv) adapting the model to fit local situations; (v) project leaders who can bring together and motivate a team; (vi) recognition and acknowledgement of the value that each member of a diverse multidisciplinary team brings; (vii) involvement of the whole team in prehabilitation prescription including identification of patients’ levels of risk through appropriate assessment and need-based interventions; (viii) persistence and determination in the development of the business case for sustainable funding; (ix) working with patients ambassadors to develop and advocate for the case for support; and (x) working closely with commissioners of healthcare.
Summary
Principles for the implementation of prehabilitation have been set out by sharing the experiences across three countries. These principles should be considered a framework for those wishing to design and develop prehabilitation services in their own areas to maximise success, effectiveness and sustainability.

Abstract
Perioperative neurocognitive disorder (PND) is a growing concern, affecting several million elderly patients each year in the United States, but strategies for its effective prevention have not yet been established. Humeidan et al. recently demonstrated that preoperative brain exercise resulted in a decrease in postoperative delirium incidence in elderly surgical patients, suggesting the potential of presurgical cognitive optimization to improve postoperative cognitive outcomes. This brief review summarizes the current knowledge regarding preoperative cognitive optimization and highlights landmark studies, as well as current ongoing studies, as the field is rapidly growing. This review further discusses the benefit of cognitive training in non-surgical elderly populations and the role of cognitive training in patients with preexisting cognitive impairment or dementia. The review also examines preclinical evidence in support of cognitive training, which can facilitate understanding of brain plasticity and the pathophysiology of PND. The literature suggests positive impacts of presurgical cognitive optimization, but further studies are encouraged to establish effective cognitive training programs for elderly presurgical patients.

Abstract
Importance Enhanced Recovery After Surgery (ERAS) is a global surgical quality improvement initiative now firmly entrenched within the field of perioperative care. Although ERAS is associated with significant clinical outcome improvements and cost savings in numerous surgical specialties, several opportunities and challenges deserve further discussion. Observations Uptake and implementation of ERAS Society guidelines, together with ERAS-related research, have increased exponentially since the inception of the ERAS movement. Opportunities to further improve patient outcomes include addressing frailty, optimizing nutrition, prehabilitation, correcting preoperative anemia, and improving uptake of ERAS worldwide, including in low- and middle-income countries. Challenges facing enhanced recovery today include implementation, carbohydrate loading, reversal of neuromuscular blockade, and bowel preparation. The COVID-19 pandemic poses both a challenge and an opportunity for ERAS. Conclusions and Relevance To date, ERAS has achieved significant benefit for patients and health systems; however, improvements are still needed, particularly in the areas of patient optimization and systematic implementation. During this time of global crisis, the ERAS method of delivering care is required to take surgery and anesthesia to the next level and bring improvements in outcomes to both patients and health systems.

Abstract
PURPOSE OF REVIEW As the surgical population ages, preoperative diagnosis and optimization of frailty becomes increasingly important. Various concepts are used to define frailty, and several tools have been validated for use in the perioperative period. This article reviews current conceptual frameworks of frailty, references current literature and provides a practical approach to the preoperative frailty assessment with a focus on potential interventions. RECENT FINDINGS A multipronged approach toward preoperative optimization should be used in patients with frailty syndrome. Oral protein supplementation and immunonutrition therapy can reduce complications in patients with malnutrition. Initiating a preoperative physical exercise regimen may mitigate frailty. Nonpharmacologic interventions to reduce preoperative anxiety and improve mood are effective, low-cost adjuncts associated with improvement in postoperative outcomes. Engaging in shared decision making is a critical component of the preoperative evaluation of frail patients. SUMMARY Emerging evidence suggests that frailty may be mitigated with patient-specific, multidimensional preoperative interventions, thus potentially improving postoperative outcomes in this vulnerable patient population.

Abstract
Enhanced Recovery Programs (ERPs) are protocols involving the whole patient surgical journey. These protocols are based on multimodal, multidisciplinary, evidence-based, and patient-centered approaches aimed at improving patient recovery after a surgical intervention. Such programs have shown striking positive results in different surgical specialties. However, only a few research groups have incorporated preoperative, intraoperative, and postoperative evidence-based interventions in bundles used to standardize care and build cardiac surgery ERPs. The Enhanced Recovery After Surgery Society recently published evidence-based recommendations for perioperative care in cardiac surgery. Their recommendations included 22 perioperative interventions that may be part of any cardiac ERP. However, various components integrated in already-published cardiac ERPs were neither graded nor reported in these recommendations. The goals of the current review are to present published cardiac ERPs and their effects on patient outcomes and reported components incorporated into these ERPs and to discuss the objectives and scope of cardiac ERPs.
