The Impact of Prehabilitation on Postoperative Functional Status, Healthcare Utilization, Pain, and Quality of Life: A Systematic Review

Preoperative lifestyle modifications combined with a structured exercise protocol on patient outcomes following total knee replacement surgery: A systematic review

BACKGROUND

Medical guidelines recommend structured prehabilitation protocols consisting of lifestyle modifications and exercise to enhance post-operative outcomes for patients undergoing a total knee replacement (TKR). However, current research showing effectiveness is limited and has primarily focused on outcomes of exercise-based prehabilitation.

OBJECTIVES

To investigate whether a structured prehabilitation protocol consisting of exercise and lifestyle modifications improves physical function and patient-reported outcomes following TKR surgery compared with usual care.

DESIGN

Systematic review.

METHODS

Five databases were searched to identify randomised controlled trials comparing structured prehabilitation programs consisting of lifestyle modifications and exercise, with usual care, for those undergoing a TKR. Methodological quality of included studies was assessed via the RoB 2.0 tool and results synthesis via a Grading of Recommendation Assessment, Development and Evaluation approach was performed to determine the certainty evidence for each outcome.

RESULTS/FINDINGS

Four studies were included in this review. Despite a positive trend supporting the inclusion of a structured prehabilitation protocol, additional improvements in post-operative pain, physical function and self-reported function were only seen in one study. Reductions in hospital length of stay were also seen in one study. No additional improvements in post-operative quality of life following prehabilitation were reported.

CONCLUSION

Limited evidence supporting prehabilitation reported in our review is likely attributed to the intervention type, intensity, and delivery model of included studies. However, there remains to be strong evidence supporting the use of a structured prehabilitation protocol consisting of lifestyle modifications and exercise to improve post-operative outcome.

Preparing for colorectal surgery: a feasibility study of a novel web-based multimodal prehabilitation programme in Western Canada

AIM

Prehabilitation for colorectal cancer has focused on exercise-based interventions that are typically designed by clinicians; however, no research has yet been patient-oriented. The aim of this feasibility study was to test a web-based multimodal prehabilitation intervention (known as PREP prehab) consisting of four components (physical activity, diet, smoking cessation, psychological support) co-designed with five patient partners.

METHOD

A longitudinal, two-armed (website without or with coaching support) feasibility study of 33 patients scheduled for colorectal surgery 2 weeks or more from consent (January-September 2021) in the province of British Columbia, Canada. Descriptive statistics analysed a health-related quality of life questionnaire (EQ5D-5L) at baseline (n = 25) and 3 months postsurgery (n = 21), and a follow-up patient satisfaction survey to determine the acceptability, practicality, demand for and potential efficacy in improving overall health.

RESULTS

Patients had a mean age of 52 years (SD 14 years), 52% were female and they had a mean body mass index of 25 kg m-2 (SD 3.8 kg m-2). Only six patients received a Subjective Global Assessment for being at risk for malnutrition, with three classified as 'severely/moderately' malnourished. The majority (86%) of patients intended to use the prehabilitation website, and nearly three-quarters (71%) visited the website while waiting for surgery. The majority (76%) reported that information, tools and resources provided appropriate support, and 76% indicated they would recommend the PREP prehab programme. About three-quarters (76%) reported setting goals for lifestyle modification: 86% set healthy eating goals, 81% aimed to stay active and 57% sought to reduce stress once a week or more. No patients contacted the team to obtain health coaching, despite broad interest (71%) in receiving active support and 14% reporting they received 'active support'.

CONCLUSION

This web-based multimodal prehabilitation programme was acceptable, practical and well-received by all colorectal surgery patients who viewed the patient-oriented multimodal website. The feasibility of providing active health coaching support requires further investigation.

The role of telemedicine in joint replacement surgery? An updated review

The usage of telemedicine and telehealth services has grown tremendously and has become increasingly relevant and essential. Technological advancements in current telehealth services have supported its use as a viable alternative tool to conduct visits for consultations, follow-up, and rehabilitation in total joint arthroplasty. Such technology has been widely implemented, particularly during the coronavirus 2019 (COVID-19) pandemic, to deliver postoperative rehabilitation among patients receiving total joint arthroplasty (TJA), further demonstrating its feasibility with a lower cost yet comparable clinical outcomes when compared with traditional care. There remains ample potential to utilize telemedicine for prehabilitation to optimize the preoperative status and postoperative outcomes of patients with osteoarthritis. In this review, various implementations of telemedicine within total joint arthroplasty and future application of telemedicine to deliver tele-prehabilitation in TJA are discussed.

Clinical practice recommendations for prehabilitation and post-operative rehabilitation for arthroplasty: A scoping review

BACKGROUND

The rising need for arthroplasty (joint replacement) has resulted in a significant increase in wait-times. Longer surgical wait-times may further exacerbate functional decline in adults with osteoarthritis as well as delay postoperative functional recovery. This review aims to better inform rehabilitation care provision before (prehabilitation) and after (post-rehabilitation) hip or knee arthroplasty based on recommendations from clinical practice guidelines (CPGs).

METHODS

This scoping review used a three-stage process to screen and extract articles, which resulted in 123 articles reviewed for analysis. Included CPGs were in the English language and focussed on rehabilitation interventions or practices involving adult patients preparing for or recuperating from hip and knee arthroplasty (published 2009-2020).

RESULTS

Patient assessments, use of assistive devices, as well as self-management and education programs were recommended before and after arthroplasty. Physiotherapy was recommended to support post-operative rehabilitation. Conversely, there was limited evidence supporting recommendations for or against physiotherapy during the prehabilitation phase of the arthroplasty care journey.

CONCLUSIONS

The findings from this review highlight the current gap in high-quality evidence supporting hip and knee arthroplasty rehabilitation CPGs before and after surgery. Findings warrant additional research to ensure patients are best prepared for surgery and supported for optimal recovery.

Multimodal prehabilitation in older adults before major abdominal surgery: a systematic review and meta-analysis

PURPOSE

Multimodal prehabilitation aims to prepare frail older patients for major surgery. The objective of this review is to determine the benefits of pre-operative multimodal prehabilitation compared to standard care in older patients.

METHODS

Data sources included MEDLINE, EMBASE, CENTRAL, CINAHL and PsychINFO. They were searched from inception to September 2021. Only randomized controlled trials (RCT) with an average study population age ≥ 65 that had undergone major abdominal operation with at least two components (physical, nutritional, psychological) of prehabilitation programs were included.

RESULTS

Nine RCTs were included with a total of 823 patients, of whom 705 completed the study with 358 undergoing prehabilitation and 347 were controls. Significantly lower complications were observed in the prehabilitation group compared to control (OR 0.67; 95% CI 0.46 to 0.99; p = 0.04; I² = 32%). A significant increase in 6-min walking distance (6MWD) from baseline to immediately prior to surgery (mean difference 35.1 m; 95%CI 11.6-58.4; p = 0.003; I² = 67%) and 8 weeks post-surgery (mean difference 44.9 m; 95%CI 6.0-83.8; p = 0.02; I² = 75%) was noted in the prehabilitation group. No difference was observed in length of stay (OR 0.59; 95% CI - 0.23 to 1.40; p = 0.16; I² = 91%) or 30-day emergency department visit (OR 0.72; 95% CI 0.41 to 1.26; p = 0.25; I² = 0%). Patient reported outcome measures were not significantly different.

CONCLUSIONS

Amongst older patients, multimodal prehabilitation increases peri-operative functional capacity and may potentially decrease post-operative complications. Future studies should continue to focus on older patients who are frail as this is the group that prehabilitation would likely have a clinically significant impact on.

The clinical application of frailty in nephrology and transplantation

PURPOSE OF REVIEW

Clinicians treating end-stage kidney disease (ESKD) and kidney transplant patients face unique challenges in their care because of the high burden of frailty in these patients. Frailty has gained significant attention by medical and surgical specialties for risk stratification in the past decades. This review highlights the importance of measuring frailty in kidney transplant candidates and recipients.

RECENT FINDINGS

Emerging data support that frailty is present even at younger ages among patients undergoing dialysis, transplant evaluation, or transplantation. It is estimated that 18.8% of younger (18-64 years) candidates, 25.2% of older (≥65 years) candidates, 14.3% of younger recipients, and 20.8% of older recipients are frail. Additionally, frailty is dynamic and subject to change pretransplantation and posttransplantation. Although many patients and clinicians are aware of the importance of measuring frailty, further studies addressing the need for interventions to reduce frailty burden are needed.

SUMMARY

Frailty is independently associated with many adverse outcomes in ESKD and kidney transplant populations. Given the growing number of ESKD and kidney transplant patients, it is pivotal to expand the utility of frailty measurement in clinical practice, recognize the burden of frailty, and identify appropriate interventions to mitigate the adverse effects of frailty.

Frailty, Race/Ethnicity, Functional Status, and Adverse Outcomes After Total Hip/Knee Arthroplasty: A Moderation Analysis

BACKGROUND

Although frailty has been shown to be associated with adverse outcomes in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA), prior studies have not examined how race/ethnicity might moderate these associations. We aimed to assess race/ethnicity as a potential moderator of the associations of frailty and functional status with arthroplasty outcomes.

METHODS

The National Surgical Quality Improvement Program was queried for patients who underwent THA or TKA from 2011 to 2017. Frailty was assessed using the modified frailty index. Regression analyses were conducted to examine associations connecting frailty/functional status with 30-day readmission, adverse discharge, and length of stay (LOS). Further analyses were conducted to investigate race/ethnicity as a potential moderator of these relationships.

RESULTS

We identified 219,143 TKA and 130,022 THA patients. Frailty and nonindependent functional status were positively associated with all outcomes (P < .001). Compared to White non-Hispanic patients, Black non-Hispanic patients had higher odds for all outcomes after TKA (P < .001) and for adverse discharge/longer LOS after THA (P < .001). Similar associations were observed for Hispanics for the adverse discharge/LOS outcomes. Race/ethnicity moderated the effects of frailty in TKA for all outcomes and in THA for adverse discharge/LOS. Race/ethnicity moderated the effects of nonindependent function in TKA for adverse discharge/LOS and on LOS alone for THA.

CONCLUSION

Disparities for Black non-Hispanic and Hispanic patients persist for readmission, adverse discharge, and LOS. However, the effects of increasing frailty and nonindependent functional status on these outcomes were the most pronounced among White non-Hispanic patients.

Advanced ovarian cancer patients identify opportunities for prehabilitation: A qualitative study

•

There are multiple disease and treatment related barriers to participating in an exercise based prehabilitation program.

•

Patients with advanced ovarian cancer are interested and motivated to take part in prehabilitation despite barriers.

•

The oncology care team has notable influence on a patient’s motivation and willingness to participate in prehabilitation.

Prehabilitation may modify frailty and increase resilience in a subset of ovarian cancer patients; however there is low adherence to most programs. Our aim was to investigate potential barriers and facilitators of prehabilitation during neoadjuvant chemotherapy (NACT). We identified 15 patients who underwent NACT from 2016 to 2018. Patients underwent a semi-structured one-on-one interview. Transcripts were coded by 4 independent reviewers to identify emerging themes related to patients’ experience, functioning and exercise during chemotherapy. Data saturation occurred after 15 interviews. Patients had a mean age of 64 and were triaged to NACT for unresectable disease in 47% of cases. Patients were overall willing to participate in exercise during chemotherapy, including walking (93%), strength training (87%), and yoga or stretching (33%). Patients identified significant factors which would motivate them to exercise during treatment despite the stated barriers, including perceived benefit to overall health and well-being, improving cancer related outcomes and a supportive treatment community. In addition, the majority of patients cited advice from their physician to participate in an exercise program as highly motivating. Cancer and treatment related symptoms such as fatigue, pain, nausea and vomiting, and respiratory distress, as well as access to care, and social and mental barriers were most often identified by patients as barriers to exercise. Patients with advanced ovarian cancer demonstrated high motivation and willingness to exercise during chemotherapy, particularly when recommended by their healthcare team and when they believe there will be a direct benefit on treatment options or cancer cure.

Effect of prehabilitation in older adults undergoing total joint replacement: An Overview of Systematic Reviews

Purpose of Review

To review and discuss the findings of systematic reviews that synthesized the evidence on the effect of preoperative exercises (prehabilitation) on postoperative functional recovery in older adults undergoing total knee or hip joint replacement.

Recent Findings

Ten systematic reviews (8 meta-analyses) were included in this review. Findings from the systematic reviews indicated that prehabilitation decreases length of hospital stay but does not improve postoperative functional recovery in older adults undergoing joint replacement. Individual studies in the systematic reviews varied considerably in prehabilitation protocol, assessment timepoints, and outcome measures. Most importantly, systematic reviews did not assess the outcomes pre-post prehabilitation as this timepoint was not addressed in most individual studies. Therefore, it is not known whether the prehabilitation programs improved outcomes preoperatively.

Summary

There is a need to develop comprehensive prehabilitation protocols and systematically assess the preoperative and postoperative effectiveness of prehabilitation protocols on functional outcomes (i.e., self-reported and performance-based) in older adults undergoing total joint replacement.

Physical Performance Tests Provide Distinct Information in Both Predicting and Assessing Patient-Reported Outcomes Following Lumbar Spine Surgery

STUDY DESIGN

Secondary analysis of randomized controlled trial data.

OBJECTIVE

The aim of this study was to examine whether preoperative physical performance is an independent predictor of patient-reported disability and pain at 12 months after lumbar spine surgery.

SUMMARY OF BACKGROUND DATA

Patient-reported outcome measures (PROMs) are commonly used to assess clinical improvement after lumbar spine surgery. However, there is evidence in the orthopedic literature to suggest that PROMs should be supplemented with physical performance tests to accurately evaluate long-term outcomes.

METHODS

A total of 248 patients undergoing surgery for degenerative lumbar spine conditions were recruited from two institutions. Physical performance tests (5-Chair Stand and Timed Up and Go) and PROMs of disability (Oswestry Disability Index: ODI) and back and leg pain (Brief Pain Inventory) were assessed preoperatively and at 12 months after surgery.

RESULTS

Physical performance tests and PROMs significantly improved over 12 months following lumbar spine surgery (P < 0.01). Weak correlations were found between physical performance tests and disability and pain (ρ = 0.15 to 0.32, P < 0.05). Multivariable regression analyses controlling for age, education, preoperative outcome score, fusion, previous spine surgery, depressive symptoms, and randomization group found that preoperative 5-Chair Stand test was significantly associated with disability and back pain at 12-month follow-up. Each additional 10 seconds needed to complete the 5-Chair Stand test were associated with six-point increase in ODI (P = 0.047) and one-point increase in back pain (P = 0.028) scores. The physical performance tests identified an additional 14% to 19% of patients as achieving clinical improvement that were not captured by disability or pain questionnaires.

CONCLUSION

Results indicate that physical performance tests may provide distinct information in both predicting and assessing clinical outcomes in patients undergoing lumbar spine surgery. Our findings suggest that the 5-Chair Stand test may be a useful test to include within a comprehensive risk assessment before surgery and as an outcome measure at long-term follow-up.

Effect of preparative rehabilitation on recovery after cardiac surgery: A systematic review

BACKGROUND

Physical prehabilitation (preparative rehabilitation) programs may have beneficial effects on enhancing physical strength and functional status before surgery, but their effects on postoperative recovery are unclear.

OBJECTIVES

This systematic review investigated the effectiveness of physical prehabilitation programs before cardiac surgery on postoperative recovery and other perioperative outcomes.

METHODS

We searched for reports of randomised controlled trials of any prehabilitation programs that included physical activity or an exercise training component in adults undergoing elective cardiac surgery, published in any language, from six bibliographic databases (last search on June 20, 2019). We assessed trials for risk of bias, overall certainty of evidence and quality of intervention reporting using the Cochrane Risk of Bias Assessment Tool, GRADE system and the Template for Intervention Description and Replication checklist and guide, respectively.

RESULTS

All 7 studies (726 participants) were at high risk of bias because of lack of blinding. The quality of prehabilitation reporting was moderate because program adherence was rarely assessed. The timing of prehabilitation ranged from 5 days to 16 weeks before surgery and from face-to-face exercise prescription to telephone counselling and monitoring. We found uncertain effects of prehabilitation on postoperative clinical outcomes (among the many outcomes assessed): perioperative mortality (Peto odds ratio 1.30, 95% confidence interval [CI] 0.28 to 5.95; I²=0%; low-certainty evidence) and postoperative atrial fibrillation (relative risk 0.75, 95% CI 0.38 to 1.46; I²=50%; very low-certainty evidence). However, prehabilitation may improve postoperative functional capacity and slightly shorten the hospital stay (mean difference -0.66 days, 95% CI -1.29 to -0.03; I²=45%; low-certainty evidence).

CONCLUSION

Despite the high heterogeneity among physical prehabilitation trials and the uncertainty regarding robust clinical outcomes, physical prehabilitation before cardiac surgery seems to enhance selected postoperative functional performance measures and slightly reduce the hospital length of stay after cardiac surgery.

Prehabilitation in patients awaiting elective coronary artery bypass graft surgery - effects on functional capacity and quality of life: a randomized controlled trial

Objective:

To determine the impact of an exercise-based prehabilitation (EBPrehab) program on pre- and postoperative exercise capacity, functional capacity (FC) and quality of life (QoL) in patients awaiting elective coronary artery bypass graft surgery (CABG).

Design:

A two-group randomized controlled trail.

Setting:

Ambulatory prehabilitation.

Subjects:

Overall 230 preoperative elective CABG-surgery patients were randomly assigned to an intervention (IG, n = 88; n = 27 withdrew after randomization) or control group (CG, n = 115).

Intervention:

IG: two-week EBPrehab including supervised aerobic exercise. CG: usual care.

Main measures:

At baseline (T1), one day before surgery (T2), at the beginning (T3) and at the end of cardiac rehabilitation (T4) the following measurements were performed: cardiopulmonary exercise test, six-minute walk test (6MWT), Timed-Up-and-Go Test (TUG) and QoL (MacNew questionnaire).

Results:

A total of 171 patients (IG, n = 81; CG, n = 90) completed the study. During EBPrehab no complications occurred. Preoperatively FC (6MWT_IG: 443.0 ± 80.1 m to 493.5 ± 75.5 m, P = 0.003; TUG_IG: 6.9 ± 2.0 s to 6.1 ± 1.8 s, P = 0.018) and QoL (IG: 5.1 ± 0.9 to 5.4 ± 0.9, P < 0.001) improved significantly more in IG compared to CG. Similar effects were observed postoperatively in FC (6MWD_IG: Δ-64.7 m, p_T1–T3 =0.013; Δ+47.2 m, p_T1–T4 <0.001; TUG_IG: Δ+1.4 s, p_T1–T3 =0.003).

Conclusions:

A short-term EBPrehab is effective to improve perioperative FC and preoperative QoL in patients with stable coronary artery disease awaiting CABG-surgery.

Peri-operative cardiac biomarker screening: a narrative review

Peri-operative risk estimation has traditionally focused on assessing the likelihood of postoperative morbidity and mortality using pre-operative functional assessment. Although this strategy is currently recommended by most major society guidelines, contemporary evidence suggests that cardiac biomarker measurement has important advantages over pre-operative functional assessment. These advantages include superior predictive discrimination and inclusion of the postoperative course in risk estimation. In this review, we provide an overview of the evidence supporting the peri-operative utilisation, compare risk estimation methods and discuss which patients may benefit most from cardiac biomarker screening. We also discuss protocols for biomarker screening and management of patients with abnormal results.

Optimizing Outpatient Total Ankle Replacement from Clinic to Pain Management

Outpatient total ankle arthroplasty is a potential significant source of cost savings. The ability to institute an effective outpatient total ankle program depends on appropriate patient selection, surgeon experience with total ankle replacement, addressing preoperative patient expectations, the involvement of an experienced multidisciplinary care team including experienced anesthesiologists, nurse navigators, recovery room nursing staff and physical therapists, and most importantly, such a program requires complete institutional logistical support.

Effects of Nutritional Prehabilitation, With and Without Exercise, on Outcomes of Patients Who Undergo Colorectal Surgery: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Although there have been meta-analyses of the effects of exercise-only prehabilitation on patients undergoing colorectal surgery, little is known about the effects of nutrition-only (oral nutritional supplements with and without counseling) and multimodal (oral nutritional supplements with and without counseling and with exercise) prehabilitation on clinical outcomes and patient function after surgery. We performed a systemic review and meta-analysis to determine the individual and combined effects of nutrition-only and multimodal prehabilitation compared with no prehabilitation (control) on outcomes of patients undergoing colorectal resection.

METHODS

We searched Medline, EMBASE, CINAHL, CENTRAL, and ProQuest for cohort and randomized controlled studies of adults awaiting colorectal surgery who received at least 7 days of nutrition prehabilitation with or without exercise. We performed a random-effects meta-analysis to estimate the pooled risk ratio for categorical data and the weighted mean difference for continuous variables. The primary outcome was length of hospital stay; the secondary outcome was recovery of functional capacity based on results of a 6-minute walk test.

RESULTS

We identified 9 studies (5 randomized controlled studies and 4 cohort studies) composed of 914 patients undergoing colorectal surgery (438 received prehabilitation and 476 served as controls). Receipt of any prehabilitation significantly decreased days spent in the hospital compared with controls (weighted mean difference of length of hospital stay = -2.2 days; 95% confidence interval = -3.5 to -0.9). Only 3 studies reported on functional outcomes but could not be pooled owing to methodologic heterogeneity. In the individual studies, multimodal prehabilitation significantly improved results of the 6-minute walk test at 4 and 8 weeks after surgery compared with standard Enhanced Recovery Pathway care and at 8 weeks compared with standard Enhanced Recovery Pathway care with added rehabilitation. The 4 observational studies had a high risk of bias.

CONCLUSIONS

In a systematic review and meta-analysis, we found that nutritional prehabilitation alone or combined with an exercise program significantly decreased length of hospital stay by 2 days in patients undergoing colorectal surgery. There is some evidence that multimodal prehabilitation accelerated the return to presurgical functional capacity.

Comprehensive Preoperative Assessment and Global Optimization

To successfully deliver greater perioperative value-based care and to effectively contribute to sustained and meaningful perioperative population health management, the scope of existing preoperative management and its associated services and care provider skills must be expanded. New models of preoperative management are needed, which rely extensively on continuously evolving evidence-based best practice, as well as telemedicine and telehealth, including mobile technologies and connectivity. Along with conventional comorbidity optimization, prehabilitation can effectively promote enhanced postoperative recovery. This article focuses on the opportunities and mechanisms for delivering value-based, comprehensive preoperative assessment and global optimization of the surgical patient.
