Effect of 8-week Pulmonary Rehabilitation Program on Dyspnea and Functional Capacity of Patients on Waiting List for Lung Transplantation

The use of digital health interventions to deliver prehabilitation in solid organ transplant recipients: are we there yet?

PURPOSE OF REVIEW

Prehabilitation, defined as preparing the body physically and psychologically for upcoming surgery is of increasing prominence in presurgical care. The aim of this review is to discuss the evidence base around prehabilitation in solid organ transplantation, the use of digital health as a tool to deliver these interventions, and consider future directions.

RECENT FINDINGS

Prehabilitation is of increasing interest as an adjunct to pretransplant care for individuals working up for solid organ transplantation. To date, research has shown that prehabilitation is acceptable and feasible; however, the literature base remains small. The majority of research has been delivered using in-person rehabilitation programmes, and the evidence base utilizing digital health as a means to deliver prehabilitation is limited.

SUMMARY

To date, the research evidence base in prehabilitation for solid organ transplantation is limited. Evidence in other surgical populations has demonstrated promising results, particularly in aerobic capacity, physical function and postoperative complications. Further high-quality randomized controlled clinical trials are required to strengthen the evidence base, understand how digital health can be harnessed and utilized to deliver multimodal prehabilitation with an aim to see how this may form part of routine care in the solid organ transplantation pathway.

Virtual Physical Prehabilitation in Lung Transplant Candidates: A Proof-of-Concept Study

This study aimed to preliminary test the effectiveness of 12-week virtual physical prehabilitation program followed by a maintenance phase. The main objective was to estimate the extent to which it affects exercise capacity, frailty, lower limb strength and health-related quality of life (HRQOL) in lung transplant candidates. The program offered supervised strengthening exercises, independent aerobic exercises and weekly phone calls (maintenance phase). Primary outcome was the six-minute walk distance (6MWD). Secondary outcomes: the Short Physical Performance Battery (SPPB), five-times sit-to-stand test (5STS), the St George's Respiratory Questionnaire (SGRQ) for HRQOL. Twenty patients were included (mean age 57.9; 6 women/14 men); fourteen completed the prehabilitation program and 5 completed the maintenance phase. There was no statistically significant improvement in 6MWD, SPPB or SGRQ after the 12-week program. Most patients either maintained or improved the 6MWT and SPPB scores. There was a significant improvement in the 5STS. After the maintenance phase, most patients either improved or maintained their scores in all outcomes except for the sub-score of symptoms in the SGRQ. A 12-week virtual physical prehabilitation program with a 12-week maintenance phase can help lung transplant candidates improve or maintain their physical function while waiting for transplantation.

European Society of Organ Transplantation (ESOT) Consensus Statement on Prehabilitation for Solid Organ Transplantation Candidates

There is increasingly growing evidence and awareness that prehabilitation in waitlisted solid organ transplant candidates may benefit clinical transplant outcomes and improve the patient's overall health and quality of life. Lifestyle changes, consisting of physical training, dietary management, and psychosocial interventions, aim to optimize the patient's physical and mental health before undergoing surgery, so as to enhance their ability to overcome procedure-associated stress, reduce complications, and accelerate post-operative recovery. Clinical data are promising but few, and evidence-based recommendations are scarce. To address the need for clinical guidelines, The European Society of Organ Transplantation (ESOT) convened a dedicated Working Group "Prehabilitation in Solid Organ Transplant Candidates," comprising experts in physical exercise, nutrition and psychosocial interventions, to review the literature on prehabilitation in this population, and develop recommendations. These were discussed and voted upon during the Consensus Conference in Prague, 13-15 November 2022. A high degree of consensus existed amongst all stakeholders including transplant recipients and their representatives. Ten recommendations were formulated that are a balanced representation of current published evidence and real-world practice. The findings and recommendations of the Working Group on Prehabilitation for solid organ transplant candidates are presented in this article.

Lung Transplant Rehabilitation-A Review

BACKGROUND

Both lung transplant recipients and candidates are characterised by reduced training capacity and low average quality of life (QoL). This review investigates the impact of training on exercise ability and QoL in patients before and after lung transplant.

METHODS

Searches were conducted from the beginning to 7 March 2022 using the terms "exercise," "rehabilitation," "lung transplant," "exercise ability," "survival," "quality of life" and "telerehabilitation" in six databases, including Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, CINAHL, Nursing and Allied Health, and Scopus. The inclusion criteria were studies evaluating the effects of an exercise training programme concurrent with lung transplantation as well as patients and candidates (>18 years old) through any lung diseases. The term "lung transplant rehabilitation" was used to refer to all carefully thought-out physical activities with the ultimate or intermediate objective of improving or maintaining physical health.

RESULTS

Out of 1422 articles, 10 clinical- and 3 telerehabilitation studies, candidates (n = 420) and recipients (n = 116) were related to the criteria and included in this review. The main outcome significantly improved in all studies. The 6-min walk distance, maximum exercise capacity, peak oxygen uptake, or endurance for constant load rate cycling improved measuring physical activity [aerobic exercises, breathing training, and aerobic and inspiratory muscle training sessions (IMT)]. Overall scores for dyspnoea improved after exercise training. Furthermore, health-related quality of life (HRQOL) also improved after aerobic exercise training, which was performed unsupervised or accompanied by breathing sessions. Aerobic training alone rather than combined with inspiratory muscle- (IMT) or breathing training enhanced exercise capacity.

CONCLUSION

In conclusion, rehabilitation programmes seem to be beneficial to patients both preceding and following lung transplantation. More studies are required to determine the best training settings in terms of time scale, frequency, and work intensity in terms of improving exercise ability, dyspnoea, and HRQOL.

Pulmonary rehabilitation of chronic pulmonary diseases (the review of clinical trials, national and international recommendations)

The review of data from randomized clinical trials, results of systematic reviews, international and national clinical recommendations on the problem of pulmonary rehabilitation in chronic pulmonary disease was carried out. This analysis of the studies included the databases eLibrary, Medline, PubMed and Cochrane libraries on the problem of pathophysiology and methods of physical rehabilitation of chronic pulmonary disease. The analysis took into account the opinions of expert groups of clinical recommendations developers of the Russian respiratory society, the European respiratory society, and the American thoracic society, presented in this review. The data of studies confirm the clinical effectiveness of physical rehabilitation methods for chronic pulmonary disease that take into account the unique needs of a complex patient. Pulmonary rehabilitation improves the physical activity, quality of life associated with health, reduces the incidence of exacerbations and mortality of patients with chronic pulmonary disease. Increasing the availability and improving pulmonary rehabilitation programs based on individual assessment of the patient's physical capabilities will increase the use of this method of treatment.

Telemedicine in lung transplant to improve patient-centered care: A systematic review

OBJECTIVES

Long-term care combined with complex follow-up processes is among the essential needs of lung transplantation. Therefore, Telemedicine-based strategies can provide an effective approach for both patients and clinicians by applying remote patient monitoring. Hence, the main objective of this study was to investigate Telemedicine and telehealth usage in lung transplantation.

METHOD

A systematic review was conducted in four databases using keywords. Eligible studies were all English papers that developed Telemedicine-based programs to enhance patient care in lung organ transplantation. The interventions were analyzed analysis to determine the main descriptive areas. The quality of the included articles was evaluated using Mixed Methods Appraisal Tool (MMAT) tool by two authors.

RESULTS

Of the 261 retrieved articles, 27 met our inclusion criteria. Of these, 22 studies were devoted to the post-transplantation phase. All articles were published from 2002 to 2021 and the trend of publications has increased in recent years. Most of the studies were conducted in the United States and Canada. All eligible studies can be categorized into five types of Telemedicine interventions, 15 (55.56%) articles devoted to Telemonitoring, four (14.81%) for Teleconsultation, four (14.81%) articles for Telerehabilitation, three (11.11%) articles for Telespirometery, and one (3.70%) article were done regarding Tele-education.

CONCLUSION

This integrated review provides researchers with a new understanding of Telemedicine-based care solutions. Findings show that remote patient care in lung transplantation includes various aspects, especially self-care improvement.

Does Preoperative Rehabilitation Influence the Quality of Life in Patients Who Are Candidates for Lung Transplant?

OBJECTIVES

Lung transplant is an excellent therapeutic option for patients with advanced/end-stage pulmonary disease. The purpose of this review was to define whether preoperative rehabilitation influences quality of life in patients who are candidates for lung transplant.

MATERIALS AND METHODS

This was a scoping review conducted by searching 4 primary databases from inception until January 2022. Three keywords, "lung transplantation," "preoperative rehabilitation," and "quality of life," were matched using the Boolean operator AND. In each database, the following fields were searched: PubMed (all fields), Scopus (title, abstract, keywords), Cochrane Library (title, abstract, keywords), and Web of Science (topic). Filters were applied for age (adult only) and language (English only). No filters were applied for gender, publication date, and subject. The search process was completed in January 2022.

RESULTS AND CONCLUSIONS

We retrieved 57 citations from these databases. After removal of duplicates, 41 documents were screened for eligibility. Two articles were included in the final analysis: 1 was a systematic review, and 1 was an observational prospective study. The rehabilitative interventions were mainly focused on motor and breathing exercises and were integrated by education programs. Preoperative rehabilitation was effective atimproving quality of life and mood status and reducing dyspnea in patients waiting for lung transplant. In addition, the 6-minute walking distance increased after patients participated in preoperative rehabilitation. Preoperative rehabilitation was composed of different types of exercise with variable duration (3-20 weeks) and frequency (3-6 times per week). Patients on the active wait list for lung transplant should be encouraged to attend preoperative rehabilitation in order to preserve and improve their quality of life.
