Preoperative physical therapy for elective cardiac surgery patients

A nomogram predicting pneumonia after cardiac surgery: a retrospective modeling study

BACKGROUND

Postoperative pneumonia (POP) is the most prevalent of all nosocomial infections in patients who underwent cardiac surgery. The aim of this study was to identify independent risk factors for pneumonia after cardiac surgery, from which we constructed a nomogram for prediction.

METHODS

The clinical data of patients admitted to the Department of Cardiothoracic Surgery of Nanjing Drum Tower Hospital from October 2020 to September 2021 who underwent cardiac surgery were retrospectively analyzed, and the patients were divided into two groups according to whether they had POP: POP group (n=105) and non-POP group (n=1083). Preoperative, intraoperative, and postoperative indicators were collected and analyzed. Logistic regression was used to identify independent risk factors for POP in patients who underwent cardiac surgery. We constructed a nomogram based on these independent risk factors. Model discrimination was assessed via area under the receiver operating characteristic curve (AUC), and calibration was assessed via calibration plot.

RESULTS

A total of 105 events occurred in the 1188 cases. Age (>55 years) (OR: 1.83, P=0.0225), preoperative malnutrition (OR: 3.71, P<0.0001), diabetes mellitus(OR: 2.33, P=0.0036), CPB time (Cardiopulmonary Bypass Time) > 135 min (OR: 2.80, P<0.0001), moderate to severe ARDS (Acute Respiratory Distress Syndrome )(OR: 1.79, P=0.0148), use of ECMO or IABP or CRRT (ECMO: Extra Corporeal Membrane Oxygenation; IABP: Intra-Aortic Balloon Pump; CRRT: Continuous Renal Replacement Therapy )(OR: 2.60, P=0.0057) and MV( Mechanical Ventilation )> 20 hours (OR: 3.11, P<0.0001) were independent risk factors for POP. Based on those independent risk factors, we constructed a simple nomogram with an AUC of 0.82. Calibration plots showed good agreement between predicted probabilities and actual probabilities.

CONCLUSION

We constructed a facile nomogram for predicting pneumonia after cardiac surgery with good discrimination and calibration. The model has excellent clinical applicability and can be used to identify and adjust modifiable risk factors to reduce the incidence of POP as well as patient mortality.

Protocol for the PORT study: short-term perioperative rehabilitation to improve outcomes in cardiac valvular surgery - a randomised control trial

INTRODUCTION

Perioperative rehabilitation (PORT) has shown a positive effect on patients undergoing cardiac surgery. However, there are minimal data on the impact of short-term PORT in cardiac surgery, which is associated with higher postoperative morbidity and mortality. The trial will assess the efficacy of short-term PORT in reducing in-hospital mortality, postoperative pulmonary complications and length of stay, compared with the usual care in cardiac surgical patients.

METHODS AND ANALYSIS

This is a single-centre prospective, randomised, open, controlled trial with a 1:1 ratio. Consecutive 800 adult patients undergoing elective valve surgery will be randomised to either usual care or in-hospital short-term PORT that consists of education, inspiratory muscle training, active cycle of breathing techniques and early mobilisation. The primary outcome of this study will be a composite of in-hospital all-cause mortality, incidence of postoperative pulmonary complications and the ratio of postoperative hospitalisation >7 days.

ETHICS AND DISSEMINATION

The PORT study was granted by the Medical Research Ethics Committee of Guangdong Provincial People's Hospital in August 2018. Findings will be disseminated to patients, clinicians and commissioning groups through peer-reviewed publication.

Prehabilitation in older patients prior to elective cardiac procedures (PRECOVERY): study protocol of a multicenter randomized controlled trial

BACKGROUND

Previous studies have demonstrated the efficacy of rehabilitation after a cardiovascular procedure. Especially older and multimorbid patients benefit from rehabilitation after a cardiac procedure. Prehabilitation prior to cardiac procedures may also have positive effects on patients' pre- and postoperative outcomes. Results of a current meta-analysis show that prehabilitation prior to cardiac procedures can improve perioperative outcomes and alleviate adverse effects. Germany currently lacks a structured cardiac prehabilitation program for older patients, which is coordinated across healthcare sectors.

METHODS

In a randomized, controlled, two-arm parallel group, assessor-blinded multicenter intervention trial (PRECOVERY), we will randomize 422 patients aged 75 years or older scheduled for an elective cardiac procedure (e.g., coronary artery bypass graft surgery or transcatheter aortic valve replacement). In PRECOVERY, patients randomized to the intervention group participate in a 2-week multimodal prehabilitation intervention conducted in selected cardiac-specific rehabilitation facilities. The multimodal prehabilitation includes seven modules: exercise therapy, occupational therapy, cognitive training, psychosocial intervention, disease-specific education, education with relatives, and nutritional intervention. Participants in the control group receive standard medical care. The co-primary outcomes are quality of life (QoL) and mortality after 12 months. QoL will be measured by the EuroQol 5-dimensional questionnaire (EQ-5D-5L). A health economic evaluation using health insurance data will measure cost-effectiveness. A mixed-methods process evaluation will accompany the randomized, controlled trial to evaluate dose, reach, fidelity and adaptions of the intervention.

DISCUSSION

In this study, we investigate whether a tailored prehabilitation program can improve long-term survival, QoL and functional capacity. Additionally, we will analyze whether the intervention is cost-effective. This is the largest cardiac prehabilitation trial targeting the wide implementation of a new form of care for geriatric cardiac patients.

Efficacy of Prehabilitation Before Cardiac Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

Patients awaiting cardiac surgery seem to benefit from exercise-based prehabilitation, but the impact on different perioperative outcomes compared with standard care is still unclear.

DESIGN

Eligible nonrandomized/randomized controlled studies investigating the impact of exercise-based prehabilitation in adults scheduled for elective cardiac surgery were searched on December 16, 2020, from electronic databases, including MEDLINE, CENTRAL, and CINAHL. The data were pooled and a meta-analysis was conducted.

RESULTS

Of 1490 abstracts, six studies ( n = 665) were included into the review and meta-analysis. At postintervention interval and at postsurgery interval, 6-min-walking distance improved significantly in exercise-based prehabilitation group compared with controls (mean difference, 75.4 m; 95% confidence interval, 13.7 to 137.1 m, P = 0.02, and 30.5 m, 95% confidence interval, 8.5 to 52.6 m, P = 0.007, respectively). Length of hospital stay was significantly shorter in exercise-based prehabilitation group (mean difference, -1.00 day; 95% confidence interval, -1.78 to -0.23 day, P = 0.01). Participation in exercise-based prehabilitation revealed a significant decrease in the risk of postoperative atrial fibrillation in patients 65 yrs or younger (risk ratio, 0.34; 95% confidence interval, 0.14 to 0.83, P = 0.02).

CONCLUSIONS

The participation in exercise-based prehabilitation significantly improves postintervention and postsurgery 6-min walking distance, length of hospital stay, and decreases the risk of postoperative atrial fibrillation in patients 65 yrs or younger compared with controls.

[Are we missing the first step? : An online expert survey in a mixed methods design on current state analysis of perioperative risk estimation and preoperative preparation of patients over 65 years old in Germany]

BACKGROUND

The proportion of patients over 65 years of age in surgical care is increasing in Germany. Frailty represents a relevant problem in the perioperative care of older patients and has a negative impact on the postoperative outcome. The individual degree of frailty can be influenced. Multimodal prehabilitation concepts can contribute to improving the degree of frailty in the perioperative care of affected patients. As a multidimensional syndrome, frailty is related to the aging process, affects multiple organ systems and typically leads to increased vulnerability to internal and external stressors. This is accompanied by a decrease in homeostatic reserves and resilience, which implies an increased risk of several adverse health outcomes, such as loss of physical function and quality of life. Prehabilitation is described as a multimodal concept to prepare patients preoperatively in the best possible way for elective surgical procedures, thereby minimizing postoperative complications and improving the patients' outcome.

METHOD

Current state analysis of perioperative care of patients over the age of 65 years in relation to frailty assessment and the use of prehabilitation concepts. Conducting a multicenter online survey of anesthesiology experts (n = 189) in German anesthesiology departments. Survey of the preoperative preparation and assessment routine in patients aged 65 years and over using a mixed methods design questionnaire.

OBJECTIVE

The aim of this study was to demonstrate the applied assessments and measures taken for specific perioperative risk assessment and preoperative preparation of patients aged 65 years and over.

RESULTS

Specific risk assessments or additional preoperative preparation of patients older than 65 years are currently not carried out routinely. The preoperative risk assessment and preparation usually focus on ascertaining the patient's previous illnesses or diseases. Assessment instruments for assessing frailty and multimodal prehabilitation concepts are not used in clinical practice in a noteworthy quantity.

CONCLUSION

In German clinical practice frailty assessment and structured prehabilitation approaches in perioperative care of older patients are not broadly known or established. Multimodal prehabilitation concepts can positively influence the outcome of older patients. To this end, it should be considered good clinical practice to assess and address frailty in older patients and to establish multimodal prehabilitation approaches tailored to this patient group.

Prehabilitation in Cardiovascular Surgery: The Effect of Neuromuscular Electrical Stimulation (Randomized Clinical Trial)

OBJECTIVE

We aimed to determine the effects of prehabilitation with neuromuscular electrical stimulation (NMES) on muscle status and exercise capacity in patients before cardiac surgery.

METHODS

Preoperative elective cardiac surgery patients were randomly assigned to the NMES group or control group. Intervention in the NMES group was 7-10 sessions, whereas the control group carried out breathing exercises and an educational program. The outcome measures included a six-minute walk test (6MWT) and a muscle status assessment (knee extensor strength (KES), knee flexor strength (KFS), and handgrip strength (HS)) after the course of prehabilitation.

RESULTS

A total of 122 patients (NMES, n = 62; control, n = 60) completed the study. During the NMES course, no complications occurred. After the course prehabilitation KES, KFS, and 6MWT distance were significantly increased (all p < 0.001) in the NMES group compared to the control. There was no significant difference in HS before surgery.

CONCLUSIONS

A short-term NMES course before cardiac surgery is feasible, safe, and effective to improve preoperative functional capacity (six-minute walk distance) and the strength of stimulated muscles.

Prehabilitation in elective patients undergoing cardiac surgery: a randomised control trial (THE PrEPS TRIAL) - a study protocol

INTRODUCTION

Prehabilitation prior to surgery has been shown to reduce postoperative complications, reduce length of hospital stay and improve quality of life after cancer and limb reconstruction surgery. However, there are minimal data on the impact of prehabilitation in patients undergoing cardiac surgery, despite the fact these patients are generally older and have more comorbidities and frailty. This trial will assess the feasibility and impact of a prehabilitation intervention consisting of exercise and inspiratory muscle training on preoperative functional exercise capacity in adult patients awaiting elective cardiac surgery, and determine any impact on clinical outcomes after surgery.

METHODS AND ANALYSIS

PrEPS is a randomised controlled single-centre trial recruiting 180 participants undergoing elective cardiac surgery. Participants will be randomised in a 1:1 ratio to standard presurgical care or standard care plus a prehabilitation intervention. The primary outcome will be change in functional exercise capacity measured as change in the 6 min walk test distance from baseline. Secondary outcomes will evaluate the impact of prehabilitation on preoperative and postoperative outcomes including; respiratory function, health-related quality of life, anxiety and depression, frailty, and postoperative complications and resource use. This trial will evaluate if a prehabilitation intervention can improve preoperative physical function, inspiratory muscle function, frailty and quality of life prior to surgery in elective patients awaiting cardiac surgery, and impact postoperative outcomes.

ETHICS AND DISSEMINATION

A favourable opinion was given by the Sheffield Research Ethics Committee in 2019. Trial findings will be disseminated to patients, clinicians, commissioning groups and through peer-reviewed publication.

Frailty Assessment and Prehabilitation Before Complex Spine Surgery in Patients With Degenerative Spine Disease: A Narrative Review

Degenerative spine disease increases in prevalence and may become debilitating as people age. Complex spine surgery may offer relief but becomes riskier with age. Efforts to lessen the physiological impact of surgery through minimally invasive techniques and enhanced recovery programs mitigate risk only after the decision for surgery. Frailty assessments outperform traditional tools of perioperative risk stratification. The extent of frailty predicts complications after spine surgery such as reoperation for infection and 30-day mortality, as well as elements of social cost such as hospital length of stay and discharge to an advanced care facility. Symptoms of spine disease overlap with phenotypic markers of frailty; therefore, different frailty assessment tools may perform differently in patients with degenerative spine disease. Beyond frailty, however, cognitive decline and psychosocial isolation may interact with frailty and affect achievable surgical outcomes. Prehabilitation, which has reduced perioperative risk in colorectal and cardiac surgery, may benefit potential complex spine surgery patients. Typical prehabilitation includes physical exercise, nutrition supplementation, and behavioral measures that may offer symptomatic relief even in the absence of surgery. Nonetheless, the data on the efficacy of prehabilitation for spine surgery remains sparse and barriers to prehabilitation are poorly defined. This narrative review concludes that a frailty assessment-potentially supplemented by an assessment of cognition and psychosocial resources-should be part of shared decision-making for patients considering complex spine surgery. Such an assessment may suffice to prompt interventions that form a prehabilitation program. Formal prehabilitation programs will require further study to better define their place in complex spine care.

Effectiveness of Preoperative Chest Physiotherapy in Patients Undergoing Elective Cardiac Surgery, a Systematic Review and Meta-Analysis

Background and Objectives: Patients undergoing cardiac surgery are particularly vulnerable for developing postoperative pulmonary complications (PPCs). This systematic review and meta-analysis aimed to evaluate the role of preoperative chest physiotherapy in such patients. Materials and Methods: All original articles that assessed patients undergoing elective cardiac surgery, with preoperative chest physiotherapy, and compared them to patients undergoing elective cardiac surgery, without preoperative chest physiotherapy, were included. Animal studies, studies conducted prior to the year 2000, commentaries, or general discussion papers whose authors did not present original data were excluded. Studies assessing physiotherapy regimens other than chest physiotherapy were also excluded. The search was performed using the following electronic resources: the Cochrane Central Register of Controlled Trials, the PubMed central database, and Embase. The included studies were assessed for potential bias using the Cochrane Collaboration’s tool for assessing the risk of bias. Each article was read carefully, and any relevant data were extracted. The extracted data were registered, tabulated, and analyzed using Review Manager software. Results: A total of 10 articles investigating 1458 patients were included in the study. The studies were published from 2006 to 2019. The populations were patients scheduled for elective CABG/cardiac surgery, and they were classified into two groups: the interventional (I) group, involving 651 patients, and the control (C) group, involving 807 patients. The meta-analysis demonstrated no significant differences between the interventional and control groups in surgery time and ICU duration, but a significant difference was found in the time of mechanical ventilation and the length of hospital stay, favoring the interventional group. A significant difference was shown in the forced expiratory volume in 1s (FEV1% _predicted), forced vital capacity (FVC% _predicted), and maximum inspiratory pressure (Pi-max), favoring the interventional group. Conclusions: This study is limited by the fact that one of the included ten studies was not an RCT. Moreover, due to lack of the assessment of certain variables in some studies, the highest number of studies included in a meta-analysis was the hospital stay length (eight studies), and the other variables were analyzed in a fewer number of studies. The data obtained can be considered as initial results until more inclusive RCTs are conducted involving a larger meta-analysis. However, in the present study, the intervention was proved to be protective against the occurrence of PPCs. The current work concluded that preoperative chest physiotherapy can yield better outcomes in patients undergoing elective cardiac surgery.

Pneumonia After Cardiovascular Surgery: Incidence, Risk Factors and Interventions

Postoperative pneumonia (POP) is prevalent in patients undergoing cardiovascular surgery, associated with poor clinical outcomes, prolonged hospital stay and increased medical costs. This article aims to clarify the incidence, risk factors, and interventions for POP after cardiovascular surgery. A comprehensive literature search was performed to identify previous reports involving POP after cardiovascular surgery. Current situation, predictors and preventive measures on the development of POP were collected and summarized. Many studies showed that POP was prevalent in various cardiovascular surgical types, and predictors varied in different studies, including advanced age, smoking, chronic lung disease, chronic kidney disease, cardiac surgery history, cardiac function, anemia, body mass index, diabetes mellitus, surgical types, cardiopulmonary bypass time, blood transfusion, duration of mechanical ventilation, repeated endotracheal intubation, and some other risk factors. At the same time, several targeted interventions have been widely reported to be effective to reduce the risk of POP and improve prognosis, including preoperative respiratory physiotherapy, oral care and subglottic secretion drainage. Through the review of the current status, risk factors and intervention measures, this article may play an important role in clinical prevention and treatment of POP after cardiovascular surgery.

Physical activity recommendations pre and post abdominal wall reconstruction: a scoping review of the evidence

PURPOSE

There are no universally agreed guidelines regarding which types of physical activity are safe and/or recommended in the perioperative period for patients undergoing ventral hernia repair or abdominal wall reconstruction (AWR). This study is intended to identify and summarise the literature on this topic.

METHODS

Database searches of PubMed, CINAHL, Allied & Complementary medicine database, PEDro and Web of Science were performed followed by a snowballing search using two papers identified by the database search and four hand-selected papers of the authors' choosing. Inclusion-cohort studies, randomized controlled trials, prospective or retrospective. Studies concerning complex incisional hernia repairs and AWRs including a "prehabilitation" and/or "rehabilitation" program targeting the abdominal wall muscles in which the interventions were of a physical exercise nature. RoB2 and Robins-I were used to assess risk of bias. Prospero CRD42021236745. No external funding. Data from the included studies were extracted using a table based on the Cochrane Consumers and Communication Review Group's data extraction template.

RESULTS

The database search yielded 5423 records. After screening two titles were selected for inclusion in our study. The snowballing search identified 49 records. After screening one title was selected for inclusion in our study. Three total papers were included-two randomised studies and one cohort study (combined 423 patients). All three studies subjected their patients to varying types of physical activity preoperatively, one study also prescribed these activities postoperatively. The outcomes differed between the studies therefore meta-analysis was impossible-two studies measured hernia recurrence, one measured peak torque. All three studies showed improved outcomes in their study groups compared to controls however significant methodological flaws and confounding factors existed in all three studies. No adverse events were reported.

CONCLUSIONS

The literature supporting the advice given to patients regarding recommended physical activity levels in the perioperative period for AWR patients is sparse. Further research is urgently required on this subject.

Quality of life following cardiac rehabilitation in cardiac surgery patients

BACKGROUND

Undergoing cardiac surgery often result in perioperative loss of health-related quality of life (HRQOL). Although participation rates in Australia is low, cardiac rehabilitation (CR) has been demonstrated to improve patient HRQOL in cardiac patients. Literature is unclear regarding the role of CR and HRQOL in the cardiac surgery (CS) patient population.

METHODS

A prospective non-randomised study was conducted on eligible cardiac surgery patients between December 2009 and March 2015. HRQOL was assessed using the Short Form 12 at baseline and post-operatively at 30 days and 180 days. CR participation was recorded and barriers to CR uptake was assessed using the Cardiac Rehabilitation Enrolment Obstacles (CREO) scale.

RESULTS

At 180 days, 107 patients participated in CR and 111 did not participate in CR. A significant improvement from baseline mental and physical HRQOL was observed in both groups at 30 days and 180 days (p < 0.002). No significant difference between group characteristics or HRQOL was observed at any time. A trend of superior improvement in mental QOL was observed in the CR group. The study is limited by poor initial uptake (218/1772 of eligible) and may be underpowered to observe a clinical difference. A significant difference in CREO scores were observed between the two groups at 30 days (13 out of 16 questions, p < 0.001) and 180 days (11 out of 16 questions, p < 0.011).

CONCLUSION

Literature has shown that CR may improve numerous health outcomes in cardiac and CS patients, however CR uptake in Australia is low. Mental and Physical QOL is demonstrated to improve following CS, however further research is required to delineate the role of CR and QOL in CS patients. The CREO tool utilised in this study identified numerous potentially modifiable barriers to CR uptake. Specific strategies related to the survey are suggested to improve awareness, uptake, and adherence to CR, including advocacy of home-based and telehealth services.

Short term high-intensity interval training in patients scheduled for major abdominal surgery increases aerobic fitness

Background

Prehabilitation may improve postoperative clinical outcomes among patients undergoing major abdominal surgery. This study evaluated the potential effects of a high-intensity interval training (HIIT) program performed before major abdominal surgery on patients’ cardiorespiratory fitness and functional ability (secondary outcomes of pilot trial NCT02953119).

Methods

Patients were included before surgery to engage in a low-volume HIIT program with 3 sessions per week for 3 weeks. Cardiopulmonary exercise and 6-min walk (6MWT) testing were performed pre- and post-prehabilitation.

Results

Fourteen patients completed an average of 8.6 ± 2.2 (mean ± SD) sessions during a period of 27.9 ± 6.1 days. After the program, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\dot{\mathrm{V}}$$\end{document}V˙O₂ peak (+ 2.4 ml min⁻¹ kg⁻¹, 95% CI 0.8–3.9, p = 0.006), maximal aerobic power (+ 16.8 W, 95% CI 8.2–25.3, p = 0.001), \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\dot{\mathrm{V}}$$\end{document}V˙O₂ at anaerobic threshold (+ 1.2 ml min⁻¹ kg⁻¹, 95%CI 0.4–2.1, p = 0.009) and power at anaerobic threshold (+ 12.4 W, 95%CI 4.8–20, p = 0.004) were improved. These changes were not accompanied by improved functional capacity (6MWT: + 2.6 m, 95% CI (− 19.6) to 24.8, p = 0.800).

Conclusion

A short low-volume HIIT program increases cardiorespiratory fitness but not walking capacity in patients scheduled for major abdominal surgery. These results need to be confirmed by larger studies.

Frailty-aware care: giving value to frailty assessment across different healthcare settings

Healthcare systems need to adapt to better serve an aging population with complex presentations. Frailty assessments are a potential means to address this heterogeneity in aging to identify individuals at increased risk for adverse health outcomes. Furthermore, frailty assessments offer an opportunity to optimize patient care in various healthcare settings. While the vast number of frailty assessment tools available can be a source of confusion for clinicians, each tool has features adaptable to the constraints and goals of different healthcare settings. This review discusses and compares barriers, facilitators, and the application of frailty assessments in primary care, the emergency department/intensive care unit and surgical care to cover a breadth of settings with different frailty assessment considerations. The implementation of frailty-aware care across healthcare settings potentiates better healthcare outcomes for older adults.

The Effect of Pre-operative Exercise Intervention on Patient Outcomes Following Bariatric Surgery: a Systematic Review and Meta-analysis

This systematic review aimed to assess the effect of a pre-operative exercise intervention on short- and long-term health and clinical outcomes for adult patients undergoing bariatric surgery (BS). We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), SPORTDiscus and reference lists of relevant papers, through March 2021. Five randomised controlled trials were included (n = 199 patients). Modest increases in cardiorespiratory fitness (VO2max) were found at both pre-operative (0.73 mL kg-1 min-1, P ≤ 0.001) and maximum follow-up time points (0.98 mL kg-1 min-1, P ≤ 0.04). There was no significant effect of an exercise intervention on percentage total weight loss (%TWL). Pre-operative exercise can induce significant short- and long-term improvements in fitness in individuals with obesity. There is insufficient evidence to determine whether pre-operative training impacts other post-operative clinical outcomes.

The effect of a smartphone-based perioperative nursing intervention: prayer, education, exercise therapy, hypnosis, and music toward pain, anxiety, and early mobilization on cardiac surgery

Background: Cardiac surgery can elicit both physical and psychological responses. Prayer, exercise therapy, education, hypnosis, and music are expected to be able to overcome pain, anxiety, and immobilization in the cardiac surgery. This study was to create a smartphone-based peri-operative nursing intervention model that was able to reduce pain, anxiety, and increase early mobilization cardiac surgery patients.

Design and methods: This study consisted of three stages. The first stage was research and development, the second was true experimental design, and the third was cross sectional design. The samples size was 86 respondents. The intervention models for the treatment group comprised of a smartphone-based therapy of prayer, education, exercise, hypnosis, and music. The control group was given standard hospital intervention according to the clinical pathway.

Results: The majority of respondents were adults, male, high school graduate in the treatment group and bachelor graduate in the control group, CABG type of surgery, and having pain history. The intervention had a significant effect on reducing pain scale and anxiety level as well as increasing early mobilization (p<0.05). The intervention had a direct effect on pain and anxiety, but it had no direct effect on early mobilization. However, it gave indirect effect on early mobilization that was mediated by anxiety.

Conclusions: The models can be used by nurses to reduce pain, anxiety and to increase early mobilization on cardiac surgery patients.

Effects of Prehabilitation on Functional Capacity in Aged Patients Undergoing Cardiothoracic Surgeries: A Systematic Review

Background: an increasing number of advanced age patients are considered for cardiothoracic surgeries. Prehabilitation optimizes the patients’ functional capacity and physiological reserve. However, the effectiveness of prehabilitation on physical functioning and postoperative recovery in the scope of cardiothoracic surgery is still uncertain. Objective: to assess the effectiveness of prehabilitation on pre- and/or postoperative functional capacity and physiological reserve in aged patients that are considered for cardiothoracic surgeries. Methods: this systematic review was registered in PROSPERO (CRD42021247117). The searches were conducted in PubMed, Web of Science, Scopus, and Cochrane CENTRAL until 18 April 2021. Randomized clinical trials that compared different prehabilitation strategies with usual care on the pre- and-postoperative results in aged patients undergoing cardiothoracic surgeries were included. Methodological quality was assessed by means of the Jadad scale, and the effectiveness of the interventions according to the Consensus on Therapeutic Exercise Training. Results: nine studies with 876 participants aged from 64 to 71.5 years old were included. Risk of bias was moderate due to the absence of double-blinding. The content of the interventions (multimodal prehabilitation n = 3; based on physical exercises n = 6) and the result measures presented wide variation, which hindered comparison across the studies. In general, the trials with better therapeutic quality (n = 6) reported more significant improvements in physical functioning, cardiorespiratory capacity, and in the postoperative results in the participants under-going prehabilitation. Conclusions: prehabilitation seems to improve functional capacity and postoperative recovery in aged patients undergoing cardiothoracic surgeries. However, due to the significant heterogeneity and questionable quality of the trials, both the effectiveness of prehabilitation and the optimum content are still to be determined.

Pre-admission interventions (prehabilitation) to improve outcome after major elective surgery: a systematic review and meta-analysis

OBJECTIVE

To determine the benefits and harms of pre-admission interventions (prehabilitation) on postoperative outcomes in patients undergoing major elective surgery.

DESIGN

Systematic review and meta-analysis of randomised controlled trials (RCTs) (published or unpublished). We searched Medline, Embase, CENTRAL, DARE, HTA and NHS EED, The Cochrane Library, CINAHL, PsychINFO and ISI Web of Science (June 2020).

SETTING

Secondary care.

PARTICIPANTS

Patients (≥18 years) undergoing major elective surgery (curative or palliative).

INTERVENTIONS

Any intervention administered in the preoperative period with the aim of improving postoperative outcomes.

OUTCOMES AND MEASURES

Primary outcomes were 30-day mortality, hospital length of stay (LoS) and postoperative complications. Secondary outcomes included LoS in intensive care unit or high dependency unit, perioperative morbidity, hospital readmission, postoperative pain, heath-related quality of life, outcomes specific to the intervention, intervention-specific adverse events and resource use.

REVIEW METHODS

Two authors independently extracted data from eligible RCTs and assessed risk of bias and the certainty of evidence using Grading of Recommendations, Assessment, Development and Evaluation. Random-effects meta-analyses were used to pool data across trials.

RESULTS

178 RCTs including eight types of intervention were included. Inspiratory muscle training (IMT), immunonutrition and multimodal interventions reduced hospital LoS (mean difference vs usual care: -1.81 days, 95% CI -2.31 to -1.31; -2.11 days, 95% CI -3.07 to -1.15; -1.67 days, 95% CI -2.31 to -1.03, respectively). Immunonutrition reduced infective complications (risk ratio (RR) 0.64 95% CI 0.40 to 1.01) and IMT, and exercise reduced postoperative pulmonary complications (RR 0.55, 95% CI 0.38 to 0.80, and RR 0.54, 95% CI 0.39 to 0.75, respectively). Smoking cessation interventions reduced wound infections (RR 0.28, 95% CI 0.12 to 0.64).

CONCLUSIONS

Some prehabilitation interventions may reduce postoperative LoS and complications but the quality of the evidence was low.

Effectiveness of Inspiratory Muscle Training on Respiratory Muscle Strength in Patients Undergoing Cardiac Surgeries: A Systematic Review With Meta-Analysis

To determine the effect of inspiratory muscle training (IMT) on pulmonary function, respiratory muscle strength (RMS), and functional capacity in patients undergoing cardiac surgery. The PubMed, PEDro, CINAHL, Web of Science, CENTRAL, and EMBASE databases were searched from inception to June 2020. Randomized controlled trials (RCTs) that evaluated patients who underwent cardiac surgery were included in this review. Meta-analysis performed using a random-effects model showed that the mean difference in forced vital capacity, forced expiratory volume in 1 second, 6-minute walk distance, and RMS was 3.47% (95% confidence interval [CI], 0.57 to 6.36), 5.80% (95% CI, 2.03 to 9.56), 78.05 m (95% CI, 60.92 to 95.18), and 4.8 cmH2O (95% CI, -4.00 to 13.4), respectively. There is strong evidence that IMT improves inspiratory muscle strength, pulmonary function, and functional capacity, and reduces the length of hospital stay in patients undergoing cardiac surgery.

Changes in Clinical Characteristics and Outcomes of Patients Admitted to Inpatient Cardiac Rehabilitation

Aims: Cardiac rehabilitation (CR) has proven to be effective and beneficial in middle-aged and older patients. However, solid data in large cohorts of elderly individuals are yet to be explored. This retrospective study investigated the general characteristics, outcomes, and the level of response of patients referred to CR over 13 consecutive years. Methods: We reviewed the medical records of patients admitted to Villa Pineta Rehabilitation Hospital for exercise-based CR from 2006 to 2018. The patients’ baseline characteristics and changes following CR in an upper-limb weightlifting test (ULW), 30-s sit-to-stand test (30STS), and the 6-min walking test (6MWT) with associated Borg-related dyspnea (D) and fatigue (F) were collected. We also calculated the number of individuals that reached the minimal clinically relevant change (MCRC) following CR for each outcome. Results: One thousand five hundred and fifty-one patients (70.2 ± 9.7 years, 66% men) with complete datasets were included in the analysis. Coronary artery bypass graft and cardiac valve replacement surgery were the most frequent surgical procedures leading to CR referral (41.1% and 35.8%, respectively). The patients’ age (p = 0.03), number of total comorbidities (p < 0.0001), and post-surgical complications (p = 0.02) significantly increased over time. In contrast, the average absolute changes in ULW, 30STS, and 6MWT with associated D and F, and the proportion of patients that reached their respective MCRC, remained constant over the same period. Conclusion: The patients admitted to exercise-based CR were older and had more comorbidities and complications over time. The outcomes, however, were not influenced in terms of the absolute change or clinically meaningful response.

Preoperative walking recommendation for non-cardiac surgery patients to reduce the length of hospital stay: a randomized control trial

BACKGROUND

Even though the importance of preparing patients for a surgical event is recognized, there are still gaps about the benefit of improving functional capacity by walking during the waiting time among patients scheduled for non-cardiac surgery. The aim of this study was to evaluate the impact of pre-surgical walking in-hospital length of stay, early ambulation, and the appearance of complications after surgery among patients scheduled for non-cardiac surgery.

METHODS

A two-arm, single- blinded randomized controlled trial was developed from May 2016 to August 2017. Eligible outpatients scheduled for non-cardiac surgery, capable of walking, were randomized (2:1 ratio) to receive a prescription of walking 150 min/week during the whole pre-surgical waiting time (n = 249) or conventional care (n = 119). The primary outcome was the difference in hospital length of stay, and secondary results were time to first ambulation during hospitalization, description of ischemic events during hospitalization and after six months of hospital discharge, and the walking continuation. We performed an intention to treat analysis and compared length of stay between both groups by Kaplan-Meier estimator (log-rank test).

RESULTS

There were no significant differences in the length of hospital stay between both groups (log-rank test p = 0.367) and no differences in the first ambulation time during hospitalization (log-rank test p = 0.299). Similar rates of postoperative complications were observed in both groups, but patients in the intervention group continued to practice walking six months after discharge (p < 0.001).

CONCLUSION

Our study is the first clinical trial evaluating the impact of walking before non-cardiac surgery in the length of stay, early ambulation, and complications after surgery. Prescription of walking for patients before non-cardiac surgery had no significant effect in reducing the length of stay, and early ambulation. The results become a crucial element for further investigation.

Prehabilitation to prevent complications after cardiac surgery - A retrospective study with propensity score analysis

Background

The rising prevalence of modifiable lifestyle-related risk factors (e.g. overweight and physical inactivity) suggests the need for effective and safe preoperative interventions to improve outcomes after cardiac surgery. This retrospective study explored potential short-term postoperative benefits and unintended consequences of a multidisciplinary prehabilitation program regarding in-hospital complications.

Methods

Data on patients who underwent elective cardiac surgery between January 2014 and April 2017 were analyzed retrospectively. Pearson’s chi-squared tests were used to compare patients who followed prehabilitation (three times per week, at a minimum of three weeks) during the waiting period with patients who received no prehabilitation. Sensitivity analyses were performed using propensity-score matching, in which the propensity score was based on the baseline variables that affected the outcomes.

Results

Of 1201 patients referred for elective cardiac surgery, 880 patients met the inclusion criteria, of whom 91 followed prehabilitation (53.8% ≥ 65 years, 78.0% male, median Euroscore II 1.3, IQR, 0.9–2.7) and 789 received no prehabilitation (60.7% ≥ 65 years, 69.6% male, median Euroscore II 1.6, IQR, 1.0–2.8). The incidence of atrial fibrillation (AF) was significantly lower in the prehabilitation group compared to the unmatched and matched standard care group (resp. 14.3% vs. 23.8%, P = 0.040 and 14.3% vs. 25.3%, P = 0.030). For the other complications, no between-group differences were found.

Conclusions

Prehabilitation might be beneficial to prevent postoperative AF. Patients participated safely in prehabilitation and were not at higher risk for postoperative complications. However, well-powered randomized controlled trials are needed to confirm and deepen these results.

Perioperative digital behaviour change interventions for reducing alcohol consumption, improving dietary intake, increasing physical activity and smoking cessation: a scoping review

BACKGROUND

Evidence suggests that unhealthy lifestyle behaviours are modifiable risk factors for postoperative complications. Digital behaviour change interventions (DBCIs), for instance text messaging programs and smartphone apps, have shown promise in achieving lifestyle behaviour change in a wide range of clinical populations, and it may therefore be possible to reduce postoperative complications by supporting behaviour change perioperatively using digital interventions. This scoping review was conducted in order to identify existing research done in the area of perioperative DBCIs for reducing alcohol consumption, improving dietary intake, increasing physical activity and smoking cessation.

MAIN TEXT

This scoping review included eleven studies covering a range of surgeries: bariatric, orthopaedic, cancer, transplantation and elective surgery. The studies were both randomised controlled trials and feasibility studies and investigated a diverse set of interventions: one game, three smartphone apps, one web-based program and five text message interventions. Feasibility studies reported user acceptability and satisfaction with the behaviour change support. Engagement data showed participation rates ranged from 40 to 90%, with more participants being actively engaged early in the intervention period. In conclusion, the only full-scale randomised controlled trial (RCT), text messaging ahead of bariatric surgery did not reveal any benefits with respect to adherence to preoperative exercise advice when compared to a control group. Two of the pilot studies, one text message intervention, one game, indicated change in a positive direction with respect to alcohol and tobacco outcomes, but between group comparisons were not done due to small sample sizes. The third pilot-study, a smartphone app, found between group changes for physical activity and alcohol, but not with respect to smoking cessation outcomes.

CONCLUSION

This review found high participant satisfaction, but shows recruitment and timing-delivery issues, as well as low retention to interventions post-surgery. Small sample sizes and the use of a variety of feasibility outcome measures prevent the synthesis of results and makes generalisation difficult. Future research should focus on defining standardised outcome measures, enhancing patient engagement and improving adherence to behaviour change prior to scheduled surgery.

Role of peri-operative exercise in patients undergoing coronary artery bypass grafting

Peri-operative exercise regimes are important to minimize complications in patients undergoing coronary artery bypass grafting (CABG). Apart from inspiratory muscle training, aerobics, resistance training, and stretching have all been reported with the potential to promote recovery after cardiac surgery. In the postoperative period, breathing exercises, aerobic and resistance exercises walking, and yoga have all been practiced. However, there is no clarity on the ideal physiotherapy regime in patients undergoing CABG or the intensity of exercise these patients can be subjected to. Future studies need to focus on these unanswered questions.

What are the impact and the optimal design of a physical prehabilitation program in patients with esophagogastric cancer awaiting surgery? A systematic review

Background

Substantial postoperative complications occur after tumor resection for esophagogastric cancers. Physical prehabilitation programs aim to prepare patients for surgery by improving their functional status with the aim of reducing postoperative complications. This systematic review aims to summarize the effects of physical prehabilitation programs on exercise capacity, muscle strength, respiratory muscle function, postoperative outcomes, and health-related quality of life and to determine the optimal design of such a program to improve these outcomes in esophagogastric cancer patients undergoing tumor resection.

Methods

A systematic literature review was conducted using PubMed, The Cochrane Library, Scopus, and PEDro databases to identify studies evaluating the effects of physical prehabilitation program on exercise capacity, muscle strength, respiratory muscle function, postoperative complications, length of hospital stay, mortality, and health-related quality of life in patients with esophagogastric cancer awaiting surgery. Data from all studies meeting the inclusion criteria were extracted. The quality of each selected study was determined using the Downs and Black checklist.

Results

Seven studies with 645 participants were included. The preoperative exercise program consisted of respiratory training alone in three studies, a combination of aerobic and resistance training in two studies, and a combination of respiratory, aerobic, and resistance training in two studies. Training frequency ranged from three times a day to twice a week and each session lasted between 20 and 75 min. Four studies were of fair quality and three of good quality. Some studies reported improvements in maximal inspiratory pressure, inspiratory muscle endurance, postoperative (pulmonary) complications, and length of hospital stay in the preoperative exercise group compared to the control group.

Conclusion

This systematic review reports the current evidence for physical prehabilitation programs in patients with esophagogastric cancer awaiting surgery. However, due to the limited number of randomized controlled trials, the significant heterogeneity of exercise programs, and the questionable quality of the studies, higher quality randomized controlled trials are needed.

Transcatheter Aortic Valve Implantation: The New Challenges of Cardiac Rehabilitation

Transcatheter aortic valve implantation (TAVI) is an increasingly widespread percutaneous intervention of aortic valve replacement (AVR). The target population for TAVI is mainly composed of elderly, frail patients with severe aortic stenosis (AS), multiple comorbidities, and high perioperative mortality risk for surgical AVR (sAVR). These vulnerable patients could benefit from cardiac rehabilitation (CR) programs after percutaneous intervention. To date, no major guidelines currently recommend CR after TAVI. However, emerging scientific evidence shows that CR in patients undergoing TAVI is safe, and improves exercise tolerance and quality of life. Moreover, preliminary data prove that a CR program after TAVI has the potential to reduce mortality during follow-up, even if randomized clinical trials are needed for confirmation. The present review article provides an overview of all scientific evidence concerning the potential beneficial effects of CR after TAVI, and suggests possible fields of research to improve cardiac care after TAVI.

The Impact of Preoperative Assessment and Planning on the Outcome of Benign Hysterectomy - a Systematic Review

Knowledge concerning the impact of preoperative planning, patient information and patient factors on the outcome of benign hysterectomy is incomplete. This systematic review summarizes the current knowledge on the effect of preoperative planning and of preoperative patient factors on the outcome of benign hysterectomy. The PubMed/PubMed Central/MEDLINE, Scopus, Web of Science, TRIP Medical Database, Prospero and the Cochrane Library databases were searched. Inclusion criteria were prospective trials, hysterectomy for benign disease, systematic preoperative assessment, and article in English. Eighteen articles were included and categorized according to their main aims: use of a preoperative checklist, preoperative decision-making, preoperative information, and the effect on the outcome of surgery of factors that concerns patients preoperatively. Focused and well directed preoperative assessment and thoroughness in the preoperative decision-making was associated with positive postoperative outcomes. The use of a checklist reduced the overall rate of hysterectomy and increased the use of minimally invasive surgery. Women were often inadequately informed before hysterectomy about the possible side effects after surgery. Preoperative anxiety and preoperative pain were associated with postoperative pain and lower quality of life. The indication for surgery had an impact on the reported quality of life postoperatively. The extent of preoperative planning seemed to affect the outcome of surgery. Preoperative patient factors influenced the postoperative recovery. Prehabilitation measures need further development and should be integrated in the preoperative planning. Prospective studies are warranted to evaluate and improve the preoperative planning in a systematic setting before performing hysterectomy for benign disease.

EFFECT OF PREOPERATIVE RESPIRATORY REHABILITATION IN PATIENTS UNDERGOING CARDIAC SURGERY

The aim of the study was to evaluate the effects of preoperative respiratory rehabilitation on functional capacity, length of stay in intensive care unit (ICU), duration of mechanical ventilation (MV) and total hospitalization, as well as to estimate arterial blood gas (ABG) values in patients undergoing cardiac surgery. Nineteen patients were included in the randomized observational study, divided into two groups: group A (intervention) and B (control). Preoperative and postoperative rehabilitation was performed in group A, and only postoperative rehabilitation in group B. Rehabilitation was carried out according to a predefined protocol. We used ABG to evaluate respiratory function, two-minute walk test (2MWT) and sit-to-stand test to assess functional capacity. The following data were obtained from medical documentation: duration of MV, length of stay at ICU, occurrence of postoperative pulmonary complications, and length of total hospitalization in both groups. Significant between-group difference was found for the length of total hospitalization and duration of MV (p<0.05 both). Analysis of the mean values of 2MWT on the last day of hospitalization (p=0.005), sit-to-stand test before surgery (p=0.022) and on the last day of hospitalization (p=0.008) showed statistically significant differences. The length of hospital stay significantly correlated with preoperative rehabilitation in group A (r=0.885; p<0.0001). There was no difference in ABG parameters between the groups. The study showed that preoperative respiratory rehabilitation had an effect on reducing duration of MV and length of total hospitalization, and improved functional capacity.

Using Wearable Devices to Monitor Physical Activity in Patients Undergoing Aortic Valve Replacement: Protocol for a Prospective Observational Study

Background

In last few decades, several tools have been developed to measure physical function objectively; however, their use has not been well established in clinical practice.

Objective

This study aims to describe the preoperative physical function and to assess and compare 6-month postoperative changes in the physical function of patients undergoing treatment for aortic stenosis with either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). The study also aims to evaluate the feasibility of wearable devices in assessing physical function in such patients.

Methods

This is a prospective observational study. The enrollment will be conducted 1 month before patients’ SAVR/TAVR. Patients will be provided with the wearable device at baseline (activity tracker device, Garmin vívoactive 3). They will be trained in the use of the device, and they will be requested to wear it on the wrist of their preferred hand until 12 months after SAVR/TAVR. After baseline assessment, they will undergo 4 follow-up assessments at 1, 3, 6, and 12 months after SAVR/TAVR. At baseline and each follow-up, they will undergo a set of standard and validated tests to assess physical function, health-related quality of life, and sleep quality.

Results

The ethics committee of Vicenza in Veneto Region in Italy approved the study (Protocol No. 943; January 4, 2019). As of October 2020, the enrollment of participants is ongoing.

Conclusions

The use of the wearable devices for real-time monitoring of physical activity of patients undergoing aortic valve replacement is a promising opportunity for improving the clinical management and consequently, the health outcomes of such patients.

Benefits of Multiple-Intervention Pulmonary Rehabilitation to Older Adults with High-Risk Multimorbidity after Coronary Artery Bypass Grafting

OBJECTIVE

Multimorbidity in elderly patients increases complications and retards the recovery of pulmonary function after coronary artery bypass grafting (CABG) surgery. We aimed to evaluate the impact of multiple-intervention pulmonary rehabilitation (PR) on respiratory muscle strength and dyspnea scores after CABG in adult patients aged ≥65 years who had multimorbidity.

METHODS

A cohort study was retrospectively conducted with 95 adults aged ≥65 years who underwent CABG surgery and completed a multiple-intervention PR program.

RESULTS

Patients in the non-multimorbidity (n = 56) and multimorbidity groups (n = 39) were evaluated on the basis of their muscle strength, degree of dyspnea, and pulmonary function. Postoperative complications were compared after the completion of PR. Between extubation days 1 and 14, the multimorbidity group showed significant improvements in maximal inspiratory pressure (16.91 vs. 24.95 cmH₂O, P < 0.001), Borg Scale score (0.99 vs. 2.3, P < 0.001), and the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV₁/FVC ratio) of 7.02% vs. 13.4% (P = 0.01). The incidence rates of pulmonary complications were similar between the two groups.

CONCLUSIONS

Multi-interventional PR program significantly improved the maximal inspiratory pressure, Borg scale score, and FEV₁/FVC ratio in the adult patients aged ≥65 years who had multimorbidity after undergoing CABG surgery.

The benefit of a preoperative respiratory protocol and musculoskeletal exercise in patients undergoing cardiac surgery

Introduction

Loss of physical activity and pulmonary dysfunction with its associated complications represent two of the most important causes of morbidity and mortality following cardiac surgery.

Aim

To evaluate whether a physiotherapy program based on respiratory training with or without musculoskeletal mobilization, started preoperatively, may provide a significant improvement in pulmonary and musculoskeletal recovery postoperatively in a sufficiently large sample of patients undergoing elective cardiac surgery.

Material and methods

One-hundred and two patients with similar baseline and preoperative characteristics were assigned to a preoperative respiratory physiotherapy protocol (group R, n = 34), a preoperative respiratory and motor physiotherapy protocol (group R + M, n = 34), or no preoperative specific physiotherapy protocol but only a simplified perioperative standard physiotherapy protocol (control group, C, n = 34). Data on 6-minute walking test, peak expiratory flow, and from blood gas analysis were retrospectively analyzed.

Results

As compared with group C, a statistically significant improvement was observed in the two preoperatively treated groups in terms of 1) better pre- (+0.7-0.8 Lt/min, p < 0.05) and postoperative (+1 Lt/min, p < 0.01) peak expiratory flow values; 2) longer pre- (+50-100 m, p < 0.01) and postoperative (+65-170 m, p < 0.01) distance traveled in the 6-minute walking test; 3) better PaO₂, SaO₂, pH value in postoperative blood gas measurements (p < 0.05, for all comparisons); 4) reduction of postoperative length of in-hospital stay (p < 0.05).

Conclusions

A benefit of combined respiratory and motor physiotherapy protocols can be expected in the groups of patients preoperatively treated, especially with the respiratory one, either before or after cardiac surgery with a faster recovery of physical-functional activities. Specifically, the motor protocol is associated with greater autonomy of running before or after cardiac surgery.

The effect of a pre- and post-operative exercise programme versus standard care on physical fitness of patients with oesophageal and gastric cancer undergoing neoadjuvant treatment prior to surgery (The PERIOP-OG Trial): Study protocol for a randomised controlled trial

BACKGROUND

Advances in peri-operative oncological treatment, surgery and peri-operative care have improved survival for patients with oesophagogastric cancers. Neoadjuvant cancer treatment (NCT) reduces physical fitness, which may reduce both compliance and tolerance of NCT as well as compromising post-operative outcomes. This is particularly detrimental in a patient group where malnutrition is common and surgery is demanding. The aim of this trial is to assess the effect on physical fitness and clinical outcomes of a comprehensive exercise training programme in patients undergoing NCT and surgical resection for oesophagogastric malignancies.

METHODS

The PERIOP-OG trial is a pragmatic, multi-centre, randomised controlled trial comparing a peri-operative exercise programme with standard care in patients with oesophagogastric cancers treated with NCT and surgery. The intervention group undergo a formal exercise training programme and the usual care group receive standard clinical care (no formal exercise advice). The training programme is initiated at cancer diagnosis, continued during NCT, between NCT and surgery, and resumes after surgery. All participants undergo assessments at baseline, post-NCT, pre-surgery and at 4 and 10 weeks after surgery. The primary endpoint is cardiorespiratory fitness measured by demonstration of a 15% difference in the 6-min walk test assessed at the pre-surgery timepoint. Secondary endpoints include measures of physical health (upper and lower body strength tests), body mass index, frailty, activity behaviour, psychological and health-related quality of life outcomes. Exploratory endpoints include a health economics analysis, assessment of clinical health by post-operative morbidity scores, hospital length of stay, nutritional status, immune and inflammatory markers, and response to NCT. Rates of NCT toxicity, tolerance and compliance will also be assessed.

DISCUSSION

The PERIOP-OG trial will determine whether, when compared to usual care, exercise training initiated at diagnosis and continued during NCT, between NCT and surgery and then during recovery, can maintain or improve cardiorespiratory fitness and other physical, psychological and clinical health outcomes. This trial will inform both the prescription of exercise regimes as well as the design of a larger prehabilitation and rehabilitation trial to investigate whether exercise in combination with nutritional and psychological interventions elicit greater benefits.

Heart Rehabilitation in patients awaiting Open heart surgery targeting to prevent Complications and to improve Quality of life (Heart-ROCQ): study protocol for a prospective, randomised, open, blinded endpoint (PROBE) trial

INTRODUCTION

The rising prevalence of modifiable risk factors (eg, obesity, hypertension and physical inactivity) is causing an increase in possible avoidable complications in patients undergoing cardiac surgery. This study aims to assess whether a combined preoperative and postoperative multidisciplinary cardiac rehabilitation (CR) programme (Heart-ROCQ programme) can improve functional status and reduce surgical complications, readmissions and major adverse cardiac events (MACE) as compared with standard care.

METHODS AND ANALYSIS

Patients (n=350) are randomised to the Heart-ROCQ programme or standard care. The Heart-ROCQ programme consists of a preoperative optimisation phase while waiting for surgery (three times per week, minimum of 3 weeks), a postoperative inpatient phase (3 weeks) and an outpatient CR phase (two times per week, 4 weeks). Patients receive multidisciplinary treatment (eg, physical therapy, dietary advice, psychological sessions and smoking cessation). Standard care consists of 6 weeks of postsurgery outpatient CR with education and physical therapy (two times per week). The primary outcome is a composite weighted score of functional status, surgical complications, readmissions and MACE, and is evaluated by a blinded endpoint committee. The secondary outcomes are length of stay, physical and psychological functioning, lifestyle risk factors, and work participation. Finally, an economic evaluation is performed. Data are collected at six time points: at baseline (start of the waiting period), the day before surgery, at discharge from the hospital, and at 3, 7 and 12 months postsurgery.

ETHICS AND DISSEMINATION

This study will be conducted according to the principles of the Declaration of Helsinki (V.8, October 2013). The protocol has been approved by the Medical Ethical Review Board of the UMCG (no 2016/464). Results of this study will be submitted to a peer-reviewed scientific journal and can be presented at national and international conferences.

The effect of preoperative respiratory physiotherapy and motor exercise in patients undergoing elective cardiac surgery: short-term results

Introduction

Loss of physical activity and pulmonary dysfunction with its associated complications represent two of the most important causes of morbidity and mortality following cardiac surgery. Few studies have investigated the effects of preoperative interventions targeted at improving cardiorespiratory and musculoskeletal function in the postoperative period.

Aim

To evaluate whether a physiotherapy program based on respiratory training with or without musculoskeletal mobilization, started preoperatively, may provide a significant improvement in pulmonary and musculoskeletal recovery postoperatively in patients undergoing elective cardiac surgery.

Material and methods

Patients with similar baseline and preoperative characteristics were randomly assigned to a preoperative respiratory physiotherapy protocol (group A), a preoperative respiratory and motor physiotherapy protocol (group B), or no preoperative specific physiotherapy protocol but only a simplified perioperative standard physiotherapy protocol (control group or group C). Group A consisted of 19 patients, group B of 20, group C of 20. Data on 6-minute walking test, peak expiratory flow, and from blood gas analysis were retrospectively analyzed.

Results

As compared with group C, a statistically significant improvement was observed in the two preoperatively treated groups A and B in terms of longer pre- and postoperative distance traveled at the 6-minute walking test, better pre- and postoperative peak expiratory flow value, and better PaO₂ and SaO₂ values in postoperative blood gas measurements (p < 0.05, for all comparisons). A statistically significant reduction of the postoperative length of in-hospital stay was also observed in group B.

Conclusions

As compared with the control group, substantially better clinical results for respiratory and musculoskeletal function were found in the groups preoperatively treated with physiotherapeutic protocols immediately before as well as after cardiac surgery.

Is incentive spirometry beneficial for patients with lung cancer receiving video-assisted thoracic surgery?

Background

The effectiveness of Incentive spirometry (IS) in patients undergoing video-assisted thoracic surgery (VATS) remains lacking. We conducted a population-based study to investigate the effectiveness of IS on patients with lung cancers following VATS.

Methods

We identified patients newly diagnosed with lung cancer who underwent surgical resection by VATS or thoracotomy from the years 2000 to 2008 in the Longitudinal Health Insurance Database. Exposure variable was the use of IS during admission for surgical resection by VATS or thoracotomy. Primary outcomes included hospitalization cost, incidence of pneumonia, and length of hospital stay. Secondary outcomes included the frequency of emergency department (ED) visits and hospitalizations at 3-month, 6-month, and 12-month follow-ups after thoracic surgery.

Results

We analyzed 7549 patients with lung cancer undergoing surgical resection by VATS and thoracotomy. The proportion of patients who were subjected to IS was significantly higher in those who underwent thoracotomy than in those who underwent VATS (68.4% vs. 53.1%, P < 0.0001). After we controlled for potential covariates, the IS group significantly reduced hospitalization costs (− 524.5 USD, 95% confidence interval [CI] = − 982.6 USD – -66.4 USD) and the risk of pneumonia (odds ratio = 0.55, 95% CI = 0.32–0.95) compared to the non-IS group following VATS. No difference in ED visit frequency and hospitalization frequency at 3-month, 6-month, and 1-year follow-up was noted between the IS and the non-IS groups following VATS.

Conclusions

The use of IS in patients with lung cancers undergoing VATS may reduce hospitalization cost and the risk of pneumonia.

PREhabilitation for improving QUality of recovery after ELective cardiac surgery (PREQUEL) study: protocol of a randomised controlled trial

INTRODUCTION

Frailty is a multidimensional syndrome in which multiple small physiological deficits accumulate gradually, resulting in a loss of physiological reserve and adaptability, putting a patient that is exposed to a stressor at a higher risk of adverse outcomes. Both pre-frailty and frailty are associated with poor patient outcomes and higher healthcare costs. The effect of a prehabilitation programme and standard care on the quality of recovery in pre-frail and frail patients undergoing elective cardiac surgery will be compared.

METHOD AND ANALYSIS

A single-centre, superiority, stratified randomised controlled trial with a blinded outcome assessment and intention-to-treat analysis. Pre-frail and frail patients awaiting elective coronary artery bypass graft, with or without valvular repair/replacement, will be recruited. 164 participants will be randomly assigned to either prehabilitation (intervention) or standard care (no intervention) groups. The prehabilitation group will attend two sessions/week of structured exercise (aerobic and resistance) training, supervised by a physiotherapist, for 6-10 weeks before surgery with early health promotion advice in addition to standard care. The standard care group will receive the usual routine care (no prehabilitation). Frailty will be assessed at baseline, hospital admission and at 1 and 3 months after surgery. The primary outcomes will be participants' perceived quality of recovery (15-item Quality of Recovery questionnaire) after surgery (day 3), days at home within 30 days of surgery and the changes in WHO Disability Assessment Schedule 2.0 score between baseline and at 1 and 3 months after surgery. Secondary outcomes will include major adverse cardiac and cerebrovascular events, psychological distress levels, health-related quality of life and healthcare costs.

ETHICS AND DISSEMINATION

The Joint CUHK-NTEC Clinical Research Ethics Committee approved the study protocol (CREC Ref. No. 2017.696 T). The findings will be presented at scientific meetings, in peer-reviewed journals and to study participants.

Decreased preoperative functional status is associated with increased mortality following coronary artery bypass graft surgery

Objectives

Functional status prior to coronary artery bypass graft surgery may be a risk factor for post-operative adverse events. We sought to examine the association between functional status in the 3 months prior to coronary artery bypass graft surgery and subsequent 180 day mortality.

Design, setting, and participants

We performed a single center retrospective cohort study in 718 adults who received coronary artery bypass graft surgery from 2002 to 2014.

Exposures

The exposure of interest was functional status determined within the 3 months preceding coronary artery bypass graft surgery. Functional status was measured and rated by a licensed physical therapist based on qualitative categories adapted from the Functional Independence Measure.

Main outcomes and measures

The main outcome was 180-day all-cause mortality. A categorical risk prediction score was derived based on a logistic regression model of the function grades for each assessment.

Results

In a logistic regression model adjusted for age, gender, New York Heart Association Class III/IV, chronic lung disease, hypertension, diabetes, cerebrovascular disease, and the Society of Thoracic Surgeons score, the lowest quartile of functional status was associated with an increased odds of 180-day mortality compared to patients with highest quartile of functional status [OR = 4.45 (95%CI 1.35, 14.69; P = 0.014)].

Conclusions

Lower functional status prior to coronary artery bypass graft surgery is associated with increased 180-day all-cause mortality.

Frailty in surgical patients

OBJECTIVE

To describe the current definitions, aetiology, assessment tools and clinical implications of frailty in modern surgical practice.

BACKGROUND

Frailty is a critical issue in modern surgical practice due to its association with adverse health events and poor post-operative outcomes. The global population is rapidly ageing resulting in more older patients presenting for surgery. With this, the number of frail patients presenting for surgery is also increasing. Despite the identification of frailty as a significant predictor of poor health outcomes, there is currently no consensus on how to define, measure and diagnose this important syndrome.

METHODS

Relevant references were identified through keyword searches of the Cochran, MEDLINE and EMbase databases.

RESULTS

Despite the lack of a gold standard operational definition, frailty can be conceptualised as a state of increased vulnerability resulting from a decline in physiological reserve and function across multiple organ systems, such that the ability to withstand stressors is impaired. Multiple studies have shown a strong association between frailty and adverse peri-operative outcomes. Frailty may be assessed using multiple tools; however, the ideal tool for use in a clinical setting has yet to be identified. Despite the association between frailty and adverse outcomes, few interventions have been shown to improve outcomes in these patients.

CONCLUSION

Frailty encompasses a group of individuals at high risk of adverse post-operative outcomes. Further work exploring ways to optimally assess and target interventions towards these patients should be the focus of ongoing research.

Pre-operative rehabilitation for dysvascular lower-limb amputee patients: A focus group study involving medical professionals

Background

Major lower-limb amputation (LLA) predisposes patients post-operatively to a significant decline in daily-life functioning. The physical condition of amputee patients prior to surgery is significantly deteriorated due to chronic peripheral vascular disease (PVD) and diabetes, which accounts for the majority of LLAs in the adult population. A common strategy called pre-rehabilitation has been used in multiple patient populations to prepare the patient for undergoing a surgical event and to improve post-operative patient outcomes. Pre-rehabilitation might enhance the outcome of dysvascular LLA patients and reduce the high post-operative mortality rates. However, experience of experts with pre-rehabilitation and feasibility of a pre-rehabilitation program in this group remains unknown.

Objective

To investigate the experiences of medical professionals and researchers in the field of LLA with the use of pre-rehabilitation in general and in particular PVD patients. Additionally, the study examines their opinions regarding need for and feasibility of a pre-rehabilitation program for dysvascular patients at risk for an LLA.

Methods

Two explorative focus group discussions were organized with in total 16 experts in the field of treatment and research of LLA. Transcribed data were coded using the Atlas.ti software package. Thematic analysis with inductive approach was opted to arrange and interpret codes.

Results

The experiences of the experts with pre-rehabilitation in dysvascular patients were scarce. The experts described dysvascular patients at risk for an LLA as a difficult group for pre-rehabilitation due to short time window prior to surgery, older age, multiple co-morbidities and lack of motivation for behavioral change. The experts concluded that a pre-rehabilitation program should focus on patients who have sufficient time in advance before the amputation for pre-rehabilitation and who are motivated to participate.

Conclusion

Although in general the effects of pre-rehabilitation are promising, pre-operative rehabilitation in dysvascular patients at risk for an LLA seems not feasible. Future research could focus on a better monitoring of dysvascular patients and the development of pre-rehabilitation in subgroups of younger dysvascular LLA patients.

Prevention of postoperative pulmonary complications through preoperative physiotherapy interventions in patients undergoing coronary artery bypass graft: literature review

[Purpose] The purpose of this review is to identify which preoperative physiotherapy interventions are applied in patients undergoing Coronary Artery Bypass Graft. [Participants and Methods] A literature review was carried out using the databases EBSCOhost, Pubmed, LILACS, IBECS, Cochrane and PEDro. Taking into consideration the inclusion and exclusion criteria, 14 studies published in 2006-2017 about preoperative physiotherapy to Coronary Artery Bypass Graft in adults were selected. [Results] Preoperative physiotherapy included interventions such as inspiratory muscle training, aerobic exercise, education in breathing exercises and counselling. Most of the studies described a combination of these interventions illustrating benefits for patients as decreasing the risk of developing postoperative pulmonary complications, reducing the length of hospitalization as well as time to extubation, anxiety and depression. [Conclusion] Preoperative Physiotherapy in patients undergoing Coronary Artery Bypass Graft includes different interventions, and their effects have been evaluated mainly through a combination of them. These combined interventions, particularly those with an inspiratory muscle training component reduce postoperative pulmonary complications. More studies are needed to identify their impact for patients.

Perioperative cognitive protection

There is significant evidence that many older surgical patients experience at least a transient decrease in cognitive function. Although there is still equipoise regarding the degree, duration, and mechanism of cognitive dysfunction, there is a concurrent need to provide best-practice clinical evidence. The two major cognitive disorders seen after surgery are postoperative delirium and postoperative cognitive dysfunction. Delirium is a public health problem; millions of dollars are spent annually on delirium-related medical resource use and prolonged hospital stays. Postoperative cognitive dysfunction is a research construct that historically signifies decline in performance on a neuropsychiatric test or group of tests and begins days to weeks after surgery. This review focuses on the current state of information gathered by several interdisciplinary stakeholder groups. Although there is still a need for high-level evidence to guide clinical practice, there is an emerging literature that can guide practitioners.

Preoperative exercise therapy for gastrointestinal cancer patients: a systematic review

BACKGROUND

Gastrointestinal cancer patients are susceptible to significant postoperative morbidity. The aim of this systematic review was to examine the effects of preoperative exercise therapy (PET) on patients undergoing surgery for GI malignancies.

METHODS

In accordance with PRISMA statement, all prospective clinical trials of PET for patients diagnosed with GI cancer were identified by searching MEDLINE, Embase, Cochrane Library, ProQuest, PROSPERO, and DARE (March 8, 2017). The characteristics and outcomes of each study were extracted and reviewed. Risk of bias was evaluated using the Cochrane risk of bias tool by two independent reviewers.

RESULTS

Nine studies (534 total patients) were included in the systematic review. All interventions involved aerobic training but varied in terms of frequency, duration, and intensity. PET was effective in reducing heart rate, as well as increasing oxygen consumption and peak power output. The postoperative course was also improved, as PET was associated with more rapid recovery to baseline functional capacity after surgery.

CONCLUSIONS

PET for surgical patients with gastrointestinal malignancies may improve physical fitness and aid in postoperative recovery.

Effectiveness of a perioperative pulmonary rehabilitation program following coronary artery bypass graft surgery in patients with and without COPD

Purpose

It is unclear whether the effectiveness of pulmonary rehabilitation program (PRP) after cardiac surgery differs between patients with and without COPD. This study aimed to compare the effectiveness of PRP between patients with and without COPD undergoing coronary artery bypass graft (CABG) surgery.

Patients and methods

We retrospectively included patients who underwent CABG surgery and received 3-week PRP from January 2009 to December 2013. We excluded patients who underwent emergency surgery, had an unstable hemodynamic status, were ventilator dependent or did not complete the PRP. Demographics, muscle strength, degree of dyspnea, pulmonary function and postoperative complications were compared.

Results

Seventy-eight patients were enrolled (COPD group, n=40; non-COPD group, n=38). Maximal inspiratory pressure (MIP; −34.52 cmH₂O vs −43.25 cmH₂O, P<0.01; −34.67 cmH₂O vs −48.18 cmH₂O, P<0.01), maximal expiratory pressure (MEP; 32.15 cmH₂O vs 46.05 cmH₂O, P<0.01; 37.78 cmH₂O vs 45.72 cmH₂O, P<0.01) and respiratory rate (RR; 20.65 breath/minute vs 17.02 breath/minute, P<0.01; 20.65 breath/minute vs 17.34 breath/minute, P<0.01) in COPD and non-COPD groups, respectively, showed significant improvement, but were not significantly different between the two groups. Forced vital capacity (FVC; 0.85 L vs 1.25 L, P<0.01), forced expiratory volume in 1 second (FEV₁; 0.75 L vs 1.08 L, P<0.01), peak expiratory flow (PEF; 0.99 L vs 1.79 L, P<0.01) and forced expiratory flow between 25% and 75% of vital capacity (FEF_25–75; 0.68 L vs 1.15 L, P<0.01) showed significant improvement between postoperative Days 1 and 14 in the COPD group. FVC (1.11 L vs 1.36 L, P<0.05), FEV₁ (96 L vs 1.09 L, P<0.05) and FEF_25–75 (1.03 L vs 1.26 L, P<0.05) were significantly improved in the non-COPD group. However, only PEF (80.8% vs 10.1%, P<0.01) and FEF_25–75 (67.6% vs 22.3%, P<0.05) were more significantly improved in the COPD group than in the non-COPD group.

Conclusion

PRP significantly improved respiratory muscle strength and lung function in patients with and without COPD who underwent CABG surgery. However, PRP is more effective in improving PEF and FEF_25–75 in COPD patients.

Nutrition and mobility predict all-cause mortality in patients 12 months after transcatheter aortic valve implantation

Background

The aim of the study was to determine pre-interventional predictors for all-cause mortality in patients after transcatheter aortic valve implantation (TAVI) with a 12-month follow-up.

Methods

From 10/2013 to 07/2015, 344 patients (80.9 ± 5.0 years, 44.5% male) with an elective TAVI were consecutively enrolled prospectively in a multicentre cohort study. Prior to the intervention, sociodemographic parameters, echocardiographic data and comorbidities were documented. All patients performed a 6-min walk test, Short Form 12 and a Frailty Index (score consisting of activities of daily living, cognition, nutrition and mobility). Peri-interventional complications were documented. Vital status was assessed over telephone 12 months after TAVI. Predictors for all-cause mortality were identified using a multivariate regression model.

Results

At discharge, 333 patients were alive (in-hospital mortality 3.2%; n = 11). During a follow-up of 381.0 ± 41.9 days, 46 patients (13.8%) died. The non-survivors were older (82.3 ± 5.0 vs. 80.6 ± 5.1 years; p = 0.035), had a higher number of comorbidities (2.6 ± 1.3 vs. 2.1 ± 1.3; p = 0.026) and a lower left ventricular ejection fraction (51.0 ± 13.6 vs. 54.6 ± 10.6%; p = 0.048). Additionally, more suffered from diabetes mellitus (60.9 vs. 44.6%; p = 0.040). While the global Frailty Index had no predictive power, its individual components, particularly nutrition (OR 0.83 per 1 pt., CI 0.72–0.95; p = 0.006) and mobility (OR 5.12, CI 1.64–16.01; p = 0.005) had a prognostic impact. Likewise, diabetes mellitus (OR 2.18, CI 1.10–4.32; p = 0.026) and EuroSCORE (OR 1.21 per 5%, CI 1.07–1.36; p = 0.002) were associated with a higher risk of all-cause mortality.

Conclusions

Besides EuroSCORE and diabetes mellitus, nutrition status and mobility of patients scheduled for TAVI offer prognostic information for 1-year all-cause mortality and should be advocated in the creation of contemporary TAVI risk scores.

Preoperative optimization for major hepatic resection

PURPOSE

Major hepatic resections are performed for primary hepatobiliary malignancies, metastatic disease, and benign lesions. Patients with chronic liver disease, including cirrhosis and steatosis, are at an elevated risk of malnutrition and impaired strength and exercise capacity, deficits which cause increased risk of postoperative complications and mortality. The aims of this report are to discuss the pathophysiology of changes in nutrition, exercise capacity, and muscle strength in patient populations likely to require major hepatectomy, and review recommendations for preoperative evaluation and optimization.

METHODS

Nutritional and functional impairment in preoperative hepatectomy patients, especially those with underlying liver disease, have a complex and multifactorial physiologic basis that is not completely understood.

RESULTS

Recognition of malnutrition and compromised strength and exercise tolerance preoperatively can be difficult, but is critical in providing the opportunity to intervene prior to major hepatic resection and potentially improve postoperative outcomes. There is promising data on a variety of nutritional strategies to ensure adequate intake of calories, proteins, vitamins, and minerals in patients with cirrhosis and reduce liver size and degree of fatty infiltration in patients with hepatic steatosis. Emerging evidence supports structured exercise programs to improve exercise tolerance and counteract muscle wasting.

CONCLUSIONS

The importance of nutrition and functional status in patients indicated for major liver resection is apparent, and emerging evidence supports structured preoperative preparation programs involving nutritional intervention and exercise training. Further research is needed in this field to develop optimal protocols to evaluate and treat this heterogeneous cohort of patients.

Hospitalization in the Year Preceding Major Oncologic Surgery Increases Risk for Adverse Postoperative Events

BACKGROUND

Hospitalization is associated with negative clinical effects that last beyond discharge. This study aimed to determine whether hospitalization in the year before major oncologic surgery is associated with adverse outcomes.

METHODS

Patients 18 years of age or older with stomach, pancreas, colon, or rectal cancer who underwent resection in California and New York (2008-2010) were included in the study. Patients with hospitalization in the year prior to oncologic resection (HYPOR) were identified. Multivariable logistic regression was used to examine the association of prior hospitalization with the following adverse outcomes: inpatient mortality, complications, complex discharge needs, and 90-day readmission. Subset analysis by cancer type was performed. Outcomes based on temporal proximity of hospitalization to month of surgical admission were evaluated.

RESULTS

Of 32,292 patients, 16.3% (n = 5276) were HYPOR. Patients with prior hospitalization were older (median age, 72 vs 67 years; p < 0.001) and had more comorbidities (Elixhauser Index ≥3, 86.5 vs 75.3%; p < 0.001). In the multivariable analysis, HYPOR was associated with complications (odds ratio [OR], 1.28; 95% confidence interval [CI] 1.18-1.40), complex discharge (OR, 1.44; 95% CI 1.34-1.55), and 90-day readmission (OR, 1.45; 95% CI 1.35-1.56). The interval from HYPOR to resection was not associated with adverse outcomes.

CONCLUSIONS

Patients hospitalized in the year before oncologic resection are at increased risk for postoperative adverse events. Recent hospitalization is a risk factor that is easily ascertainable and should be used by clinicians to identify patients who may need additional support around the time of oncologic resection.

Evaluation of a physiatrist-directed prehabilitation intervention in frail patients with colorectal cancer: a randomised pilot study protocol

INTRODUCTION

Prehabilitation interventions have shown efficacy in the orthopaedic and cardiothoracic surgical populations, but there has been limited evidence for general surgical patients. We present the protocol for a pilot trial of a novel prehabilitation intervention, consisting of a physiatrist-directed preoperative assessment and treatment programme.

METHODS AND ANALYSIS

This is a single-centre pilot randomised controlled trial investigating physiatrist-directed prehabilitation for a 4 to 6-week preoperative period. We will block randomise 40-50 participants awaiting surgery for colorectal cancer to prehabilitation versus control. Participants in the prehabilitation arm will undergo assessment by a physiatrist and enrol in a supervised exercise programme. The control group will not undergo any prehabilitation interventions in the preoperative period. Our primary outcome is feasibility, measured by examining recruitment, refusal, retention and adherence rates as well as participant satisfaction and feedback. Secondary outcomes include physical fitness, functional ability, health-related quality of life, postoperative complications, mortality, readmissions, length of stay, prehabilitation interventions performed and exercise complications.

ETHICS AND DISSEMINATION

This study has been approved by the Hamilton Integrated Research Ethics Board (HIREB reference number 2015-0090-GRA). The results of this pilot study will be used to design a full-scale study and published in peer-reviewed journals.

Frailty, Aging, and Cardiovascular Surgery

Older adults make up an ever-increasing number of patients presenting for surgery, and a significant percentage of these patients will be frail. Frailty is a geriatric syndrome that has been conceptualized as decreased reserve when confronted with stressors, although the precise definition of frailty has not been easy to standardize. The 2 most popular approaches to define frailty are the phenotypic approach and the deficit accumulation approach, although at least 20 tools have been developed, which has made comparison across studies difficult. In epidemiologic studies, baseline frailty has been associated with poor outcomes in both community cohorts and hospitalized patients. Specifically in cardiac surgery (including transcatheter aortic valve implantation procedures), frailty has been strongly associated with postoperative mortality and morbidity, and thus frailty likely improves the identification of high-risk patients beyond known risk scores. For perioperative physicians then, the question arises of how to incorporate this information into perioperative care. To date, 2 thrusts of research and clinical practice have emerged: (1) preoperative identification of high-risk patients to guide both patient expectations and surgical decision-making; and (2) perioperative optimization strategies for frail patients. However, despite the strong association of frailty and poor outcomes, there is a lack of well-designed trials that have examined perioperative interventions with a specific focus on frail patients undergoing cardiac surgery. Thus, in many cases, principles of geriatric care may need to be applied. Further research is needed to standardize and implement the feasible definitions of frailty and examine perioperative interventions for frail patients undergoing cardiac surgery.
