Supervised pulmonary tele-rehabilitation versus pulmonary rehabilitation in severe COPD: a randomised multicentre trial

Delivery of Allied Health Interventions Using Telehealth Modalities: A Rapid Systematic Review of Randomized Controlled Trials

Objectives: To determine whether allied health interventions delivered using telehealth provide similar or better outcomes for patients compared with traditional face-to-face delivery modes. Study design: A rapid systematic review using the Cochrane methodology to extract eligible randomized trials. Eligible trials: Trials were eligible for inclusion if they compared a comparable dose of face-to-face to telehealth interventions delivered by a neuropsychologist, occupational therapist, physiotherapist, podiatrist, psychologist, and/or speech pathologist; reported patient-level outcomes; and included adult participants. Data sources: MEDLINE, CENTRAL, CINAHL, and EMBASE databases were first searched from inception for systematic reviews and eligible trials were extracted from these systematic reviews. These databases were then searched for randomized clinical trials published after the date of the most recent systematic review search in each discipline (2017). The reference lists of included trials were also hand-searched to identify potentially missed trials. The risk of bias was assessed using the Cochrane Risk of Bias Tool Version 1. Data Synthesis: Fifty-two trials (62 reports, n = 4470) met the inclusion criteria. Populations included adults with musculoskeletal conditions, stroke, post-traumatic stress disorder, depression, and/or pain. Synchronous and asynchronous telehealth approaches were used with varied modalities that included telephone, videoconferencing, apps, web portals, and remote monitoring, Overall, telehealth delivered similar improvements to face-to-face interventions for knee range, Health-Related Quality of Life, pain, language function, depression, anxiety, and Post-Traumatic Stress Disorder. This meta-analysis was limited for some outcomes and disciplines such as occupational therapy and speech pathology. Telehealth was safe and similar levels of satisfaction and adherence were found across modes of delivery and disciplines compared to face-to-face interventions. Conclusions: Many allied health interventions are equally as effective as face-to-face when delivered via telehealth. Incorporating telehealth into models of care may afford greater access to allied health professionals, however further comparative research is still required. In particular, significant gaps exist in our understanding of the efficacy of telehealth from podiatrists, occupational therapists, speech pathologists, and neuropsychologists.

Increasing exercise capacity and physical activity in the COPD patient

Higher levels of exercise capacity and physical activity are desired outcomes in the comprehensive management of the COPD patient. In addition, improvements in exercise capacity and physical activity are instrumental to optimising other important therapeutic goals, such as improved health status, reduced healthcare utilisation and increased survival. Four general approaches towards increasing exercise capacity and physical activity in individuals with COPD will be discussed in this review: 1) pharmacological intervention, especially the administration of long-acting bronchodilators; 2) pulmonary rehabilitation, including exercise training and collaborative self-management; 3) behavioural interventions; and 4) web-based interventions. These are by no means the only approaches, nor are they mutually exclusive: indeed, combining them, as necessary, to meet the needs of the individual respiratory patient may promote optimal outcomes, although further research is necessary in this area.

Point: Center-Based Pulmonary Rehabilitation Is the Standard

Currently, a major pulmonary rehabilitation focus is on expanding access. At-home rehabilitation is being explored as an in-center pulmonary rehabilitation alternative. It has been asserted that in-home pulmonary rehabilitation confers similar benefits to in-center pulmonary rehabilitation. An extensive database documents that in-center pulmonary rehabilitation confers a range of patient-relevant benefits. Recently, evidence has been presented that in-center pulmonary rehabilitation improves survival, perhaps the most important benefit of all. It can be argued that improvements in physical fitness, assessed as exercise capacity, are mechanistically related to survival improvements. Therefore, in-home rehabilitation must demonstrate exercise capacity improvements similar to those regularly seen in-center to be considered equivalent. A literature search identified 11 studies that compared in-home with in-center pulmonary rehabilitation for COPD that recorded exercise tolerance outcomes. Despite being described as in-home programs, almost all featured prefatory in-center evaluation; some featured in-home visits by rehabilitation professionals. In 6 of the 11 studies, only walking exercise was prescribed. Only 3 included 2-way audio/visual patient-therapist contact. With regard to exercise outcomes; in 3, there was greater in-center group improvement; in 4, outcomes were similar; and, in 4, the in-center group failed to demonstrate clinically important exercise outcome increases; decidedly mixed results. Importantly, in 8 of 11 studies, the 6-min walk test was an exercise outcome. It is argued that the 6-min walk test does not generally elicit physiologically maximum responses and cannot be used to assess exercise capacity improvements. Of the 4 studies that used other exercise outcomes, in 2, exercise endurance increase was similar between in-home and in-center groups; in the other 2, the in-center group had superior improvements. Mixed results indeed! In conclusion, there is insufficient evidence to conclude that in-home pulmonary rehabilitation yields improvements equivalent to center-based programs in physical function, the outcome likely driving long-term prognosis. Moreover, it needs to be established which of the wide variety of in-home program designs now being offered should be promoted.

Barriers to Pulmonary Rehabilitation

Pulmonary rehabilitation (PR) is one of the most effective therapies for chronic respiratory diseases, yet it is significantly underutilized. There are several patient-related, geographic, societal, and health system-related barriers to PR. People with chronic respiratory disease face a collectively high burden of treatments including health care provider visits, medications, oxygen and other durable medical equipment, and providers' recommendation to undertake PR may be considered an added burden more than a likely benefit. Transportation difficulties, lack of insurance coverage, competing time priorities, low knowledge of PR, lack of perceived likely benefit, comorbidities, and other factors also pose obstacles to participation in PR for patients. Geographic availability of PR is heterogenous; in the United States, out-patient center-based PR programs are often not available within close proximity to patients' residence, posing barriers to patients' access to it. PR programs are lacking altogether in many areas; rural areas are particularly affected. Existing PR programs are often poorly funded and underresourced. Socioeconomic and racial disparities also influence patients' likelihood of receiving PR. Also, health care professionals (HCPs) often do not refer their patients with chronic respiratory disease to PR, owing to a lack of knowledge and awareness of its content and benefits, patient candidacy, or of the referral process. A limited number of multidisciplinary HCPs trained in PR likely also contributes to limited access to PR for patients. Collectively, these multifaceted barriers to PR create unacceptable health care disparities. Strategies to address barriers to PR are urgently needed in order to enable individuals who need to receive it.

Telerehabilitation in Physical Therapist Practice: A Clinical Practice Guideline From the American Physical Therapy Association

A clinical practice guideline on telerehabilitation was developed by an American Physical Therapy Association volunteer guideline development group consisting of international physical therapists and physiotherapists, a physician, and a consumer. The guideline was based on systematic reviews of current scientific literature, clinical information, and accepted approaches to telerehabilitation in physical therapist practice. Seven recommendations address the impact of, preparation for, and implementation of telerehabilitation in physical therapist practice. Research recommendations identify current gaps in knowledge. Overall, with shared decision-making between clinicians and patients to inform patients of service delivery options, direct and indirect costs, barriers, and facilitators of telerehabilitation, the evidence supports the use of telerehabilitation by physical therapists for both examination and intervention. The Spanish and Chinese versions of this clinical practice guideline, as well as the French version of the recommendations, are available as supplementary material (Suppl. Materials).

Changes in physical activity, sedentary behaviour and sleep following pulmonary rehabilitation: a systematic review and network meta-analysis

BACKGROUND

The variety of innovations to traditional centre-based pulmonary rehabilitation (CBPR), including different modes of delivery and adjuncts, are likely to lead to differential responses in physical activity, sedentary behaviour and sleep.

OBJECTIVES

To examine the relative effectiveness of different pulmonary rehabilitation-based interventions on physical activity, sedentary behaviour and sleep.

METHODS

Randomised trials in chronic respiratory disease involving pulmonary rehabilitation-based interventions were systematically searched for. Network meta-analyses compared interventions for changes in physical activity, sedentary behaviour and sleep in COPD.

RESULTS

46 studies were included, and analyses were performed on most common outcomes: steps per day (k=24), time spent in moderate-to-vigorous physical activity (MVPA; k=12) and sedentary time (k=8). There were insufficient data on sleep outcomes (k=3). CBPR resulted in greater steps per day and MVPA and reduced sedentary time compared to usual care. CBPR+physical activity promotion resulted in greater increases in steps per day compared to both usual care and CBPR, with greater increases in MVPA and reductions in sedentary time compared to usual care, but not CBPR. Home-based pulmonary rehabilitation resulted in greater increases in steps per day and decreases in sedentary time compared to usual care. Compared to usual care, CBPR+physical activity promotion was the only intervention where the lower 95% confidence interval for steps per day surpassed the minimal important difference. No pulmonary rehabilitation-related intervention resulted in greater increases in MVPA or reductions in sedentary time compared to CBPR.

CONCLUSION

The addition of physical activity promotion to pulmonary rehabilitation improves volume of physical activity, but not intensity, compared to CBPR. High risk of bias and low certainty of evidence suggests that these results should be viewed with caution.

Real-time telerehabilitation for chronic respiratory disease and post-COVID-19: A systematic review and meta-analysis

INTRODUCTION

Telerehabilitation may facilitate access and adherence to pulmonary rehabilitation. Given the heterogeneity in existing telerehabilitation studies, it is still necessary to identify the most effective, safe, and cost-efficient strategy for clinical implementation, as well as the necessary level of supervision during telerehabilitation. The aim of this review was to determine the effectiveness and safety of real-time telerehabilitation for chronic respiratory diseases and post-COVID-19 compared to no-rehabilitation, center-based rehabilitation or asynchronous telerehabilitation.

METHODS

A comprehensive search was conducted in six databases until 30 April 2023. Clinical trials of real-time telerehabilitation supervised via videoconference in adults with diagnosis of any chronic respiratory disease or post-COVID-19 were included.

RESULTS

Twelve studies with 1540 participants were included. Very-low to moderate certainty evidence showed no difference between real-time telerehabilitation and center-based pulmonary rehabilitation. Studies included in this review reported high adherence rates to real-time telerehabilitation and completion rate, with no difference compared to center-based pulmonary rehabilitation. When compared to no-rehabilitation, the results of this review provide low-certainty evidence that real-time telerehabilitation may have a potential effect on exercise capacity at the end of the intervention, with no better results in others outcomes. No studies comparing real-time telerehabilitation with asynchronous telerehabilitation were found.

CONCLUSION

Real-time telerehabilitation is safe and it seems to promote similar effects to center-based pulmonary rehabilitation. However, the certainty of this evidence ranged from very-low to moderate. Therefore, real-time telerehabilitation offers an alternative to center-based pulmonary rehabilitation models. This review provides a clear definition of real-time telerehabilitation, facilitating results interpretation and clinical applicability.

Effectiveness of guided telerehabilitation on functional performance in community-dwelling older adults: A systematic review

OBJECTIVE

To systematically review the effectiveness of guided telerehabilitation on improving functional performance in community-dwelling older adults.

DATA SOURCES

Articles published in PubMed, Cochrane Library and Embase (Ovid) from 01 January 2010 up to 17 October 2023.

REVIEW METHODS

Included studies had (1) a randomised controlled trial design, (2) an average population age of 65 years or older, (3) a home-based setting and (4) evaluated the effectiveness of functional performance outcome measures. The intervention was considered telerehabilitation when guided by a healthcare professional using video, audio and/or text communication technologies with a minimum frequency of once per week. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis 2020 statement guideline was followed. Methodological quality was appraised using the revised Cochrane Risk of Bias tool.

RESULTS

A total of 26 randomised controlled trials were included. Telerehabilitation had superior (N = 15), non-superior (N = 16) or non-inferior (N = 11) effectiveness for improving functional performance outcome measures compared to control interventions. No studies found the control intervention to be superior over telerehabilitation. Between study differences in intervention characteristics contributed to significant clinical heterogeneity. Five studies were found to present an overall 'low' risk of bias, 12 studies to present 'some' risk of bias and 9 studies to present an overall 'high' risk of bias.

CONCLUSION

The findings suggest that telerehabilitation could be a promising alternative to in-person rehabilitation for improving functional performance in community-dwelling older adults. Additional well-designed studies with minimised bias are needed for a better understanding of effective telerehabilitation intervention strategies.

Effect of internet-based pulmonary rehabilitation on physical capacity and health-related life quality in patients with chronic obstructive pulmonary disease-a systematic review and meta-analysis

PURPOSE

Pulmonary rehabilitation (PR) is now recognized as the most effective treatments for individuals with chronic obstructive pulmonary disease (COPD), internet-based PR arises a promising method. The aim of this study was to conduct a systematic review and meta-analysis for assessing the effect of internet-based PR programs on physical capacity and health-related quality of life in patients with COPD.

MATERIALS AND METHODS

Randomized controlled trials were identified through systematically searches in PubMed, EMBASE, web of science, CENTRAL, Cochrane Library, and Google Scholar databases.

RESULTS

Twelve studies (1433 patients) were included. For physical capacity, there was no significant difference between groups was found according to the 6-min walk test (6MWT) (MD10.42, 95% CI -2.92 to 23.77, p = 0.13, I2 = 0%). For the health-related quality of life, no significant difference between groups was found regarding the St George's Respiratory Questionnaire (SGRQ) (MD -0.64, 95% CI -3.52 to 2.23, p = 0.66), COPD assessment test (CAT)(MD -0.34, 95% CI -1.62 to 0.94, p = 0.60), modified Medical Research Council scale (mMRC)(MD 0.17, 95% CI -0.06 to 0.39, p = 0.15) and Chronic Respiratory Questionnaire (CRQ)(MD 1.32 95% CI -5.88 to 8.53, p = 0.72).

CONCLUSIONS

This study has established the potential for delivery of PR via the internet in demonstrating non-inferiority of physical capacity and health-related quality of life (HRQoL) compared with conventional PR.IMPLICATIONS FOR REHABILITATIONLong-term rehabilitation training for patients with chronic obstructive pulmonary disease needs a more convenient and feasible way.In this study, internet-based rehabilitation showed similar effects as conventional rehabilitation on physical activity and health-related quality of life.Internet-based rehabilitation strategies would be helpful for this population.All internet-based rehabilitation strategies should be simple and sustainable.

Effectiveness of Telemedicine Interventions in Chronic Obstructive Pulmonary Disease (COPD) Management: A Randomized Controlled Trial Comparing Yoga Therapy and Pulmonary Rehabilitation Over Three Months

Background Pulmonary rehabilitation (PR) is an integral part of non-pharmacological therapy in chronic obstructive pulmonary disease (COPD). Yoga therapy (YT) has been shown to be beneficial in COPD, but the lack of large well-designed trials and standardized modules restricts its acceptability. This randomized control trial compares these two modalities in COPD patients via supervised tele-intervention. Objectives The primary objective of the study is to compare a 45-minute, five-days-per-week series of tele-YT (T-YT) with tele-PR (T-PR) for three months in terms of exercise capacity (6-Minute Walk Distance (6MWD)) in COPD patients. Methods COPD patients were randomly assigned (1:1) to T-YT or T-PR groups in a parallel-arm single-blinded controlled trial. The primary outcome is 6MWD recorded at baseline and after three months and secondary outcomes were symptom scores, Forced expiratory volume in the first second (FEV1), health-related quality of life (HrQoL), and depression and anxiety scores. Assessments were conducted at baseline and at the end of the three-month study period with a sample size of 75 in each group. Results A total of 150 consecutive patients with COPD were randomly assigned to either the T-YT (n = 75) or T-PR (n = 75) group. Their mean ± SD ages was 62.5 ± 7.0 years. The T-YT group had 55.5% males and 34.47% females, whereas the T-PR group had 44.5% males and 61.53% females. The trial was completed by 123 patients; 88% in the T-YT group and 76% in the T-PR group. Pre-intervention, the median (range) of 6MWD in T-YT and T-PR groups was 240 (120-600) m and 240 (120-660) m, respectively. There was statistically significant improvement in both groups respectively (p<0.001) post intervention from baseline but no significant intergroup difference (p = 0.486). A similar trend was seen in secondary outcomes with significant intragroup improvements and non-significant inter-group differences except FEV1%, which showed neither intragroup nor intergroup significant improvement. Conclusion Using a validated module, a three-month T-YT improves exercise capacity, symptom scores, HrQoL, and depression and anxiety scores similar to T-PR. T-YT is an acceptable alternative to T-PR in the management of COPD.

Telehealth interventions in occupational therapy with older adults: Results from a scoping review targeting better health promotion

INTRODUCTION

Telehealth interventions have the potential to enhance access to care and improve efficiency while reducing the burden on patients. Although telehealth interventions are well accepted and adopted in physical therapy, their usage in occupational therapy for older adults is less common, and limited information exists regarding their setting and context.

OBJECTIVE

To provide an inventory and synthesis of telehealth interventions in occupational therapy for older adults.

METHOD

For published studies on telehealth-based occupational therapy interventions in older adults between 2000 and 2022, six databases were reviewed. Data extraction and analysis were guided by the taxonomies developed by Tulu, McColl and Law and informed by the Canadian Model of Occupational Performance and Engagement.

FINDINGS

Twenty-three studies on telehealth interventions in occupational therapy for older adults were identified, mostly from North American authors (n = 11; 47.8%) and randomised clinical trials (n = 9; 39.1%). Most participants had a health problem (n = 20; 87.0%), mainly stroke (n = 9; 39.1%). Interventions focussed primarily on symptom management education (n = 12; 52.2%) of community-dwelling adults with health conditions, using videoconferencing systems or applications (n = 14; 60.7%). Interventions were delivered from the healthcare centre (n = 6; 26.1%) to the person's home (n = 18; 78.3%) synchronously (n = 19; 82.6%). About one third (n = 8; 34.8%) of the studies specified the therapist's location.

CONCLUSION

Published studies on telehealth interventions in occupational therapy with older adults have mainly focussed on the synchronous training and education of participants using videoconferencing systems or applications. According to these studies, the scope of interventions is limited and could be expanded, for example, through occupational development and environmental modification. To better understand and describe best practices in the use of telehealth in occupational therapy, future studies should provide more details about the interventions performed, the technology used and the environmental settings of the therapist.

Feasibility of a home-designed respiratory rehabilitation program for chronic obstructive pulmonary disease

BACKGROUND

According to international guidelines, respiratory rehabilitation (RR) for patients with chronic obstructive pulmonary disease (COPD) is a cornerstone of standard non-pharmacological treatment.

AIMS

To evaluate feasibility of a home-designed RR program and analyze its medium-term impact on respiratory parameters and quality of life.

METHODS

This was a prospective study involving 74 COPD patients enrolled in January 2019 and put on inhaled bronchodilator treatment associated with RR at home following a written protocol, for 16 weeks. The comparative statistical analysis highlights the difference before and after RR in terms of clinical and functional respiratory parameters as well as in terms of quality of life (assessed on the short form 36 (SF-36) questionnaire). The comparison involves RR-adherent patients versus non-adherent patients.

RESULTS

Mean age was 66.7 ± 8.3 years with a median of 67 years. All patients were smokers, out of which 42 patients (57%) did not quit yet. Forty-one percent of patients were frequent exacerbators. The average COPD assessment test (CAT) score in our patients was 23. The average 6-minutes walk distance (MWD) was 304 m. The BODE index in our patients was 4.11 on average. The RR program was followed by 36 patients (48%). Thirty patients (40%) applied it at least twice a week. RR-adherent patients had an average CAT score decreasing from 23 to 14.5 (P = 0.011). Their average 6-MWD was 444.6 m by the end of the study, which would be 64.2% of the calculated theoretical value. The average FEV1 increase after RR was 283 mL. The majority (69%) of RR-adherent patients were ranked as quartile 1; BODE index ≤2. The average scores of physical, psycho-social, and general dimensions assessed on the SF-36 questionnaire improved in RR-adherent patients.

CONCLUSIONS

RR is a key non-pharmacological treatment for COPD. Its interest originates from its multidisciplinary nature, hence its effectiveness in several respiratory parameters. Our study reflects the feasibility of home-designed protocols in the absence of contraindications. We highlight also the positive impact on quality of life after RR at home.

Enrollment and dropout rates of individuals with chronic obstructive pulmonary disease approached for telehealth interventions: A systematic review and meta-regression analysis

Introduction

Telehealth interventions have the potential of improving health outcomes for individuals with chronic obstructive pulmonary disease (COPD). However, the precise impact of telehealth on exacerbation and hospital readmissions remains inconclusive. This lack of knowledge on the effectiveness of telehealth for COPD care might be due to lack of clarity regarding which variables are most strongly associated with enrolment and dropout rates.

Objectives

Among individuals with COPD in telehealth studies, we aimed to: (1) estimate the extent to which trial-related variables are associated with enrolment and dropout rates, and identify reasons for dropouts; (2) estimate the extent to which patients-related and intervention-related variables are associated with dropout rates; (3) estimate the effect of enrolment rate and dropout rate on effect size; (4) estimate the effect of trial-related, patient-related, and intervention-related variables on effect size.

Methods

A systematic literature search was conducted using four electronic databases. Two independent reviewers screened all retrieved titles, abstracts and full texts according to the inclusion criteria and extracted the data. A random-effect meta-regression analysis was conducted to estimate the overall enrolment and dropout rates, and estimated the different variables' effects on the enrolment rate, dropout rate, and effect sizes in the studies included in the review.

Results

A total of 56 studies comprising 7530 participants were identified. The estimated enrolment and dropout rates were 50.3 % and 14.9 %, respectively. Trial-related variables influence enrollment and dropout rates, including RCT designs and the recruitments. The patient-related variables, including age and severity of the disease, and intervention-related variables, including the components of the intervention and mode of delivery, influence dropout rates. Studies with low dropout rates had a bigger effect size by 0.23. The main reported reasons for dropping out of the intervention were related to death (21 %) followed by lost to follow-up (14 %).

Conclusion

Trial, patient, and intervention-related variables were found to influence the enrolment and dropout rates. This would help plan and develop a more appealing telehealth intervention that patients can easily accept and incorporate into their everyday lives.

Digital physiotherapy is a satisfactory and effective method to improve the quality of life in Long COVID patients

Objective

This research aimed to explore Long COVID patient's quality of life, satisfaction and perception with an individualized and customizable digital physiotherapy intervention during a 4-week period.

Methods

A pre-post clinical trial was conducted with 32 Long COVID patients. Quality of life was assessed using the 12-Item Short Form Survey and the European Quality of Life-5 Dimensions questionnaire (EuroQol-5D), while satisfaction and perception were measured using the Telemedicine Satisfaction Questionnaire. Optional open-ended questions were added as qualitative approach. A mixed design method was conducted.

Results

After intervention, a statistically significant improvement (p < 0.05) was observed in quality of life. The SF-12 questionnaire showed an increase of 4.04 points in the physical component and 6.55 points in the mental component with a small/medium effect size. The EuroQoL-5D questionnaire demonstrated a medium effect size with an increase of 0.87 points. Patient perception indicated high rates of satisfaction and values above the minimal clinically important difference. The qualitative approach revealed several interesting findings.

Conclusion

Participants found the digital intervention satisfactory and effective in improving their quality of life. Suggestions for improvement, such as the inclusion of face-to-face sessions, a chat for immediate contact, sound in breath exercises in the digital program, longer duration and continuity of intervention, were mentioned. Larger sample studies and in-deep qualitative methodologies are needed to draw extrapolable conclusions.

Functional capacity and quality of life improvement in stable chronic obstructive pulmonary disease (COPD) patients following physical exercise and chicken egg white supplementation

The pillars of comprehensive pulmonary rehabilitation program for chronic obstructive pulmonary disease (COPD) patients include physical exercise and good nutrition. The aim of this study was to evaluate the efficacy of pulmonary rehabilitation, which included physical exercise and chicken egg white supplementation, on the quality of life (QoL) and functional capacity among patients with stable COPD. The COPD patients were enrolled prospectively in this quasi-experimental study and completed a 12-week smartphone-guided home-based physical exercise program that comprised strength and resistance training three times per week for 30 minutes each session. Participants were divided into two groups: the control group who underwent physical exercise only, and the intervention group who had physical exercise and chicken egg white supplementation as a protein source. Patient characteristics including sex, age, nutritional status, comorbidities, smoking status, and obstruction severity, were evaluated. The COPD assessment test (CAT) score and six-minute walk test (6MWT) were used as the parameters to evaluate QoL and functional capacity, respectively. Of the total 50 patients included in the study, 12 were excluded due to follow-up and adherence problems. Our data indicated there were significant CAT score reduction and 6MWT improvement in both control and intervention groups after 12 weeks compared to baseline data. However, reduction of mean CAT score was higher in intervention compared to control group (-13.47±6.49 vs -5.42±5.07, p<0.001). In addition, the improvement of 6MWT was also higher in intervention group compared to control group (145.47±69.2 vs 32.42±17.3 meters, p<0.001). In conclusion, chicken egg white supplement to male patients with stable COPD who exercise with resistance and strength training could improve the QoL and functional capacity.

Consideration of Sex, Gender, or Age on Outcomes of Digital Technologies for Treatment and Monitoring of Chronic Obstructive Pulmonary Disease: Overview of Systematic Reviews

BACKGROUND

Several systematic reviews have addressed digital technology use for treatment and monitoring of chronic obstructive pulmonary disease (COPD).

OBJECTIVE

This study aimed to assess if systematic reviews considered the effects of sex, gender, or age on the outcomes of digital technologies for treatment and monitoring of COPD through an overview of such systematic reviews. The objectives of this overview were to (1) describe the definitions of sex or gender used in reviews; (2) determine whether the consideration of sex, gender, or age was planned in reviews; (3) determine whether sex, gender, or age was reported in review results; (4) determine whether sex, gender, or age was incorporated in implications for clinical practice in reviews; and (5) create an evidence map for development of individualized clinical recommendations for COPD based on sex, gender, or age diversity.

METHODS

MEDLINE, the Cochrane Library, Epistemonikos, Web of Science, and the bibliographies of the included systematic reviews were searched to June 2022. Inclusion was based on the PICOS framework: (1) population (COPD), (2) intervention (any digital technology), (3) comparison (any), (4) outcome (any), and (5) study type (systematic review). Studies were independently selected by 2 authors based on title and abstract and full-text screening. Data were extracted by 1 author and checked by another author. Data items included systematic review characteristics; PICOS criteria; and variables related to sex, gender, or age. Systematic reviews were appraised using A Measurement Tool to Assess Systematic Reviews, version 2 (AMSTAR 2). Data were synthesized using descriptive statistics.

RESULTS

Of 1439 records, 30 systematic reviews published between 2010 and 2022 were included in this overview. The confidence in the results of 25 of the 30 (83%) reviews was critically low according to AMSTAR 2. The reviews focused on user outcomes that potentially depend on sex, gender, or age, such as efficacy or effectiveness (25/30, 83%) and acceptance, satisfaction, or adherence (3/30, 10%) to digital technologies for COPD. Reviews reported sex or gender (19/30 systematic reviews) or age (25/30 systematic reviews) among primary study characteristics. However, only 1 of 30 reviews included age in a subgroup analysis, and 3 of 30 reviews identified the effects of sex, gender, or age as evidence gaps.

CONCLUSIONS

This overview shows that the effects of sex, gender, or age were rarely considered in 30 systematic reviews of digital technologies for COPD treatment and monitoring. Furthermore, systematic reviews did not incorporate sex, gender, nor age in their implications for clinical practice. We recommend that future systematic reviews should (1) evaluate the effects of sex, gender, or age on the outcomes of digital technologies for treatment and monitoring of COPD and (2) better adhere to reporting guidelines to improve the confidence in review results.

Effect of Video Camera Angle on the Detection of Compensatory Movements during Motion Observation

When exercise instructions are provided over the Internet, such as in online personal training, an instructor checks the user's form by watching their motion video recorded using a single camera device. However, fixed shooting angles may affect the detection of incorrect forms, including compensatory movements. This study aimed to verify whether differences in the shooting direction could influence compensatory movement detection by conducting motion observation using training motion videos shot from two angles. Videos of four training movements, including compensatory movements, were simultaneously captured from the front and side. Ten university students studying physical therapy watched the videos from each angle to detect compensatory movements. This study revealed significant differences between the plane of motion in which the compensatory action occurred and the direction of shooting for the false responses in the compensatory action detection for the three movements (p < 0.05). The results indicated that the shooting direction and the plane of motion in which the compensatory action occurred affected the detection of compensatory movements, which was attributable to differences in information on the amount of joint change depending on the direction of joint motion observation and to a lack of binocular visual information necessary for depth motion detection.

Physiotherapist-led, exercise-based telerehabilitation for older adults improves patient and health service outcomes: a systematic review and meta-analysis

BACKGROUND

Telerehabilitation can be an appropriate alternative to face-to-face rehabilitation for adults; however, it is uncertain whether it is safe and effective for older adults.

OBJECTIVE

This review aimed to determine the effect of physiotherapist-led, exercise-based telerehabilitation for older adults on patient outcomes (health-related quality of life, activity limitation, functional impairment) and health service costs.

METHODS

Randomised or non-randomised controlled trials including community-dwelling older adults (mean age ≥ 65 years) who received exercise-based telerehabilitation led by a physiotherapist were eligible. Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, PubMed and Cochrane Library were searched from the earliest available date to August 2022. Methodological quality was assessed using the Physiotherapy Evidence Database scale. Data were synthesised with inverse variance, random-effects meta-analyses to determine standardised mean differences and 95% confidence intervals. Certainty of evidence was determined by applying Grading of Recommendations, Assessment, Development and Evaluation criteria.

RESULTS

Eleven studies (10 randomised) with 1,400 participants (mean age 65-74 years) experiencing musculoskeletal and cardiopulmonary conditions were included. Telerehabilitation was safe, effective and well adhered to. Telerehabilitation was non-inferior to face-to-face physiotherapy in relation to range of movement, strength, 6-min walk distance (6MWD), timed up and go test (TUGT) and quality of life and had lower health-care costs compared with face-to-face physiotherapy. Compared with no intervention, telerehabilitation participants had significantly better range of motion, strength, quality of life, 6MWD and TUGT speed.

CONCLUSION

Physiotherapist-led, exercise-based telerehabilitation is non-inferior to face-to-face rehabilitation and better than no intervention for older adults with musculoskeletal and cardiopulmonary conditions.

Mobile Phone App-Based or Face-to-Face Pulmonary Rehabilitation in COVID-19 Survivors

Background

Pulmonary Rehabilitation (PR) is recommended as a standard, effective, and important treatment for COVID-19 survivors who remain symptomatic after the acute phase. Therefore, we aimed to compare the effect of mobile phone-based PR application with face-to-face PR on the quality of life, anxiety, depression, and daily life activities of COVID-19 survivors.

Materials and Methods

A quasi-experimental was conducted on 65 COVID-19 survivors during 2022. Convenient sampling was done based on the inclusion criteria. The intervention group (n = 31) received PR through a mobile phone application, and the control group (n = 34) received face-to-face PR. Data were collected before and after the intervention in both groups using a demographic information questionnaire, SF-12, the hospital anxiety and depression scale, and Barthel scale. For all tests, a maximum error of 5% was considered.

Results

The two studied groups had no statistically significant difference with respect to all the investigated variables at baseline (p > 0.05). After the intervention, the mean anxiety and depression score of the patients in the control group was significantly lower than the intervention group (t = -3.46, f = 63, p = 0.01). After our intervention, there was no statistically significant difference in the mean quality of life and daily life activity scores between the two groups (t = -0.68, f = 63, p > 0.05).

Conclusions

The application of PR does not show a statistically significant difference in terms of improving the quality of life and daily activities compared with the face-to-face method; we suggest that the PR application be used as a cost-effective method when face-to-face PR is not possible.

A scoping review of the feasibility, acceptability, and effects of physiotherapy delivered remotely

PURPOSE

To review the feasibility, acceptability, and effects of physiotherapy when delivered remotely.

MATERIALS AND METHODS

CINAHL, MEDLINE, EBM Reviews, and Cochrane Library databases (January 2015-February 2022) were searched and screened for papers (of any design) investigating remote physiotherapy. Data were extracted by two independent raters. Methodological quality of the identified papers was not assessed. Thematic content analysis drew out the key issues.

RESULTS

Forty-one papers (including nine systemic reviews and six with meta-analyses) were selected involving musculoskeletal, stroke and neurological, pulmonary, and cardiac conditions. The most commonly delivered intervention was remote exercise provision, usually following assessment which was completed in-person. All studies, which assessed it, found that remote physiotherapy was comparably effective to in-person delivery at lower cost. Patient satisfaction was high, they found remote physiotherapy to be more accessible and convenient. It boosted confidence and motivation by reminding patients when and how to exercise but adherence was mixed. No adverse events were reported. Barriers related to access to the technology; technical problems and concerns about therapists' workload.

CONCLUSIONS

Remote physiotherapy is safe, feasible, and acceptable to patients. Its effects are comparable with traditional care at lower cost.IMPLICATIONS FOR REHABILITATIONRemote physiotherapy is safe, feasible, and acceptable to patients with comparable effects to in-person care.Remote delivery increases access to physiotherapy especially for those who cannot travel to a treatment facility whether due to distance or disability.Remote physiotherapy may increase adherence to exercise by reminding patients when and how to exercise.Remote physiotherapy does not suit everyone, thus a hybrid system with both in-person and remote delivery may be most effective.

Developing a home-based pulmonary rehabilitation programme for patients with chronic respiratory diseases in Malaysia: A mixed-method feasibility study

Background

The COVID-19 pandemic has underscored the importance of remote healthcare and home-based interventions, including pulmonary rehabilitation, for patients with chronic respiratory diseases (CRDs). It has also heightened the vulnerability of individuals with underlying respiratory conditions to severe illness from COVID-19, necessitating exploration and assessment of the feasibility of delivering home - pulmonary rehabilitation (home-PR) programmes for CRD management in Malaysia and other countries. Home-based programmes offer a safer alternative to in-person rehabilitation during outbreaks like COVID-19 and can serve as a valuable resource for patients who may be hesitant to visit healthcare facilities during such times. We aimed to assess the feasibility of delivering a home-PR programme for patients with CRDs in Malaysia.

Methods

We recruited patients with CRDs from two hospitals in Klang Valley, Malaysia to a home-PR programme. Following centre-based assessment, patients performed the exercises at home (five sessions/week for eight weeks (total 40 sessions)). We monitored the patients via weekly telephone calls and asked about adherence to the programme. We measured functional exercise capacity (6-Minutes Walking Test (6MWT) and Health-Related Quality-of-Life (HRQoL) (COPD Assessment Test (CAT)) at baseline and post-PR at nine weeks. We conducted semi-structured interviews with 12 purposively sampled participants to explore views and feedback on the home-PR programme. The interviews were audio recorded, transcribed verbatim, and analysed thematically.

Results

We included 30 participants; two withdrew due to hospitalisation. Although 28 (93%) adhered to the full programme, only 11 (37%) attended the post-PR assessment because COVID-19 movement restrictions in Malaysia at that time prevented attendance at the centre. Four themes emerged from the qualitative analysis: involvement of family and caregivers, barriers to home-PR programme, interactions with peers and health care professionals, and programme enhancement.

Conclusion

Despite the COVID-19 pandemic, the home-PR programme proved feasible for remote delivery, although centre-based post-PR assessments were not possible. Family involvement played an important role in the home-PR programme. The delivery of this programme can be further improved to maximise the benefit for patients.

Pulmonary telerehabilitation vs. conventional pulmonary rehabilitation - a secondary responder analysis

Home-based pulmonary telerehabilitation (PTR) has been proposed to be equivalent to supervised outpatient pulmonary rehabilitation (PR) but available randomised trials have failed to reach the minimal important changes (MIC). The purpose of this study was to analyse the proportion of MIC responders and non-responders on short-term (10 weeks from baseline) and long-term (62 weeks from baseline) in total and between groups in 134 patients with COPD randomised (1:1) to either home-based PTR or traditional hospital-based outpatient PR. Difference between PTR and PR on 6MWD response proportion could not be shown at 10 (OR=0.72, CI=0.34 to 1.51, p=0.381) or 62 weeks (OR=1.12, CI=0.40 to 3.14, p=0.834). While the evidence and knowledge of PTR accumulate, outpatient supervised PR for now remains the standard of care, with home-based PTR as a strong secondary option for those unable to attend out-patient programmes.

[Efficacy of tele-rehabilitation in patients with chronic obstructive pulmonary disease: A systematic review]

Since 2020 we have lived an exceptional situation that made us experience a complete lockdown due to SARS-CoV-2, what affected the treatments of different pathologies, such as the chronic obstructive pulmonary disease (COPD). Because of those reasons, it has arisen the idea of implementing the tele-rehabilitation program as a treatment of these pathologies. The search was done between the months of October and November 2020, with the aim of analyzing and updating the efficacy of the tele-rehabilitation in patients who have COPD, finding eight articles which met the inclusion criteria. The pulmonary tele-rehabilitation is able to improve the quality of life and physical state, and decreasing the number of hospitalizations and exacerbations. Furthermore, patients showed a great level of satisfaction and adherence to this treatment program. The pulmonary tele-rehabilitation can achieve similar results as of pulmonary rehabilitation. For this reason, people who have difficulties to go to their outpatients clinic or even in a lockdown can use it. However, it is necessary to investigate which tele-rehabilitation program is better.

Pulmonary Rehabilitation for Adults with Chronic Respiratory Disease: An Official American Thoracic Society Clinical Practice Guideline

Background: Despite the known benefits of pulmonary rehabilitation (PR) for patients with chronic respiratory disease, this treatment is underused. Evidence-based guidelines should lead to greater knowledge of the proven benefits of PR, highlight the role of PR in evidence-based health care, and in turn foster referrals to and more effective delivery of PR for people with chronic respiratory disease. Methods: The multidisciplinary panel formulated six research questions addressing PR for specific patient groups (chronic obstructive pulmonary disease [COPD], interstitial lung disease, and pulmonary hypertension) and models for PR delivery (telerehabilitation, maintenance PR). Treatment effects were quantified using systematic reviews. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to formulate clinical recommendations. Recommendations: The panel made the following judgments: strong recommendations for PR for adults with stable COPD (moderate-quality evidence) and after hospitalization for COPD exacerbation (moderate-quality evidence), strong recommendation for PR for adults with interstitial lung disease (moderate-quality evidence), conditional recommendation for PR for adults with pulmonary hypertension (low-quality evidence), strong recommendation for offering the choice of center-based PR or telerehabilitation for patients with chronic respiratory disease (moderate-quality evidence), and conditional recommendation for offering either supervised maintenance PR or usual care after initial PR for adults with COPD (low-quality evidence). Conclusions: These guidelines provide the basis for evidence-based delivery of PR for people with chronic respiratory disease.

The Impact of Patient Preference on Attendance and Completion Rates at Centre-Based and mHealth Pulmonary Rehabilitation: A Non-Inferiority Pragmatic Clinical Trial

Purpose

Pulmonary rehabilitation (PR) is vital in the management of chronic respiratory disorders (CRDs) although uptake, attendance and completion are poor. Differing models of delivering PR are emerging in an attempt to increase the uptake and completion of this intervention. This study aimed to evaluate participant rate of attendance and completion of PR when given a preference regarding model of delivery (centre-based and mPR). Secondary aims were to evaluate the factors affecting patient preference for model of delivery and determine whether mPR is non-inferior to centre-based PR in health outcomes.

Methods

A multi-centre non-inferiority preference based clinical trial in Auckland, New Zealand. Participants with a CRD referred for PR were offered the choice of centre-based or mHealth PR (mPR). The primary outcome was completion rate of chosen intervention.

Results

A total of 105 participants were recruited to the study with 67 (64%) preferring centre-based and 38 (36%) mPR. The odds of completing the PR programme were higher in the centre-based group compared to mPR (odds ratio 1.90 95% CI [0.83-4.35]). Participants opting for mPR were significantly younger (p = 0.002) and significantly more likely to be working (p = 0.0001). Results showed that mPR was not inferior to centre-based regarding changes in symptom scores (CAT) or time spent in sedentary behaviour (SBQ). When services were forced to transition to telehealth services during COVID-19 restrictions, the attendance and completion rates were higher with telephone calls and video conferencing compared to mPR - suggesting that synchronous interpersonal interactions with clinicians may facilitate the best attendance and completion rates.

Conclusion

When offered the choice of PR delivery method, the majority of participants preferred centre-based PR and this facilitated the best completion rates. mPR was the preferred choice for younger, working participants suggesting that mPR may offer a viable alternative to centre-based PR for some participants, especially younger, employed participants.

Telerehabilitation in pulmonary diseases

PURPOSE OF REVIEW

Telerehabilitation is an alternative delivery model for pulmonary rehabilitation, an evidence-based nonpharmacological intervention, in people with chronic pulmonary disease. This review synthesizes current evidence regarding the telerehabilitation model for pulmonary rehabilitation with an emphasis on its potential and implementation challenges, as well as the clinical experiences from the COVID-19 pandemic.

RECENT FINDINGS

Different models of telerehabilitation for delivering pulmonary rehabilitation exist. Current studies comparing telerehabilitation to centre-based pulmonary rehabilitation primarily focus on the evaluation in people with stable chronic obstructive pulmonary disease, which demonstrated equivalent improvements in exercise capacity, health-related quality of life and symptoms with improved programme completion rates. Although telerehabilitation may improve access to pulmonary rehabilitation by addressing travel burden, improving schedule flexibility and geographic disparity, there are challenges of ensuring satisfaction of healthcare interactions and delivering core components of initial patient assessment and exercise prescription remotely.

SUMMARY

Further evidence is needed on the role of telerehabilitation in various chronic pulmonary diseases, as well as the effectiveness of different modalities in delivering telerehabilitation programmes. Economic and implementation evaluation of currently available and emerging models of telerehabilitation in delivering pulmonary rehabilitation are needed to ensure sustainable adoption into clinical management for people with chronic pulmonary disease.

Quality of life between home-based and outpatient pulmonary rehabilitation in patients after surgical resection for lung cancer: protocol for a prospective, single-blind, randomised controlled trial

INTRODUCTION

Lung cancer remains a highly fatal disease. Surgical resection has been proven to be the most effective treatment for early-stage lung cancer. The conventional hospital-based pulmonary rehabilitation (PR) is shown to reduce symptoms, improve exercise capacity and impact the quality of life (QoL) for lung cancer patients. To date, scientific evidence on the effectiveness of home-based PR for patients with lung cancer following surgery is scarce. We aim to explore if home-based PR is non-inferior to outpatient PR for patients with lung cancer following surgical resection.

METHODS AND ANALYSIS

This study is a two-arm, parallel-group, assessor-blind, single-centre, randomised controlled trial. Participants will be recruited from West China Hospital, Sichuan University and randomly allocated to either an outpatient group or a home-based group at a ratio of 1:1. The PR programme involves self-management and exercises. The exercise includes warm-up (10 min), aerobic training (20 min), resistance training (15 min) and cool-down (10 min), lasting 4 weeks, with two sessions per week either at home or in the outpatient setting. The intensity will be adjusted according to the modified Borg rating of perceived exertion and heart rate before and after each exercise session. The primary outcome is QoL measured by EORTC QLQ-C30 & LC 13 after an intervention. Secondary outcomes include physical fitness measured by a 6 min walk test and stair-climbing test and symptom severity measured by patient-reported questionnaires and pulmonary function. The main hypothesis is that home-based PR is non-inferior to outpatient PR for patients with lung cancer following surgical resection.

ETHICS AND DISSEMINATION

The trial has been approved by the Ethical Committee of West China Hospital and is also registered with the Chinese Clinical Trial Registry. The results of this study will be disseminated through peer-reviewed publications and presentations at national and international conferences.

Pilot testing the impact of an aerobic exercise plus rehabilitation training on respiratory function in older adults with COPD

Chronic obstructive pulmonary disease (COPD) is a chronic intractable lung disease. To investigate the therapeutic effect, older adult patients were subjected to aerobic exercise and respiratory rehabilitation (diaphragmatic breathing) for six months. At the end of six-month intervention, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), 6-minute walking distance (6 MWD), and patient activation measure scores increased; St. George's respiratory questionnaire scores and disease impact score decreased; and PaCO₂ and PaO₂ were significantly improved in both groups, particularly in the experimental group. In addition, FEV1, FEV1/FVC, 6 MWD, blood gas levels, quality of life, and self-care ability in the experimental group were significantly improved compared with those in the control group, and the improvements were significantly greater in male, younger, and less diseased patients. Our study demonstrated that aerobic exercise combined with diaphragmatic breathing significantly improves respiratory function and quality of life in older adult patients.

Long-term Telerehabilitation or Unsupervised Training at Home for Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial

Rationale: Despite the benefits of pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD), many patients do not access or complete pulmonary rehabilitation, and long-term maintenance of exercise is difficult. Objectives: To compare long-term telerehabilitation or unsupervised treadmill training at home with standard care. Methods: In an international randomized controlled trial, patients with COPD were assigned to three groups (telerehabilitation, unsupervised training, or control) and followed up for 2 years. Telerehabilitation consisted of individualized treadmill training at home supervised by a physiotherapist and self-management. The unsupervised training group performed unsupervised treadmill exercise at home. The control group received standard care. The primary outcome was the combined number of hospitalizations and emergency department presentations. Secondary outcomes included time free from the first event; exercise capacity; dyspnea; health status; quality of life; anxiety; depression; self-efficacy; and subjective impression of change. Measurements and Main Results: A total of 120 participants were randomized. The incidence rate of hospitalizations and emergency department presentations was lower in telerehabilitation (1.18 events per person-year; 95% confidence interval [CI], 0.94-1.46) and unsupervised training group (1.14; 95% CI, 0.92-1.41) than in the control group (1.88; 95% CI, 1.58-2.21; P < 0.001 compared with intervention groups). Telerehabilitation and unsupervised training groups experienced better health status for 1 year. Intervention participants reached and maintained clinically significant improvements in exercise capacity. Conclusions: Long-term telerehabilitation and unsupervised training at home in COPD are both successful in reducing hospital readmissions and can broaden the availability of pulmonary rehabilitation and maintenance strategies.

Videoconferencing interventions and COPD patient outcomes: A systematic review

INTRODUCTION

Videoconferencing circumvents various physical and financial barriers associated with in-person care. Given this technology's potential benefits and timely nature, we conducted a systematic review to understand how videoconferencing for chronic obstructive pulmonary disease (COPD) follow-up care affects patient-related outcomes.

METHODS

We included primary research evaluating the use of bidirectional videoconferencing for COPD patient follow-up. The outcomes of interest were resource utilization, mortality, lifestyle factors, patient satisfaction, barriers, and feasibility. We searched MEDLINE, EMBASE, EBM Reviews, and CINAHL databases for articles published from January 1, 2010, to August 2, 2021. Relevant information was extracted and presented descriptively and common themes and patterns were identified. The risk of bias for each study was assessed using design-specific validated tools.

RESULTS

We included 39 studies of 18,194 patients (22 quantitative, 12 qualitative, and 5 mixed methods). The included studies were grouped by type of intervention; 18 studies explored videoconferencing for exercise, 19 explored videoconferencing for clinical assessment/monitoring, and 2 examined videoconferencing for education. Generally, videoconferencing was associated with high levels of patient satisfaction. There were mixed results in terms of its effects on resource utilization and lifestyle-related factors. Additionally, 12 studies were at high risk of bias, indicating that these results should be interpreted with caution.

CONCLUSIONS

The videoconferencing interventions resulted in high levels of patient satisfaction, despite facing technological issues. Overall, more research is needed to better understand the effects of videoconferencing interventions on resource utilization and other patient outcomes, quantifying their advantages over in-person care.

Role of digital health in pulmonary rehabilitation and beyond: shaping the future

Pulmonary rehabilitation (PR) is a cost-effective intervention with well-known benefits to exercise capacity, symptoms and quality of life in patients with chronic respiratory diseases. Despite the compelling evidence of its benefits, PR implementation is still suboptimal, and maintenance of PR benefits is challenging. To overcome these pitfalls, there has been a growing interest in developing novel models for PR delivery. Digital health is a promising solution, as it has the potential to address some of the most reported barriers to PR uptake and adherence (such as accessibility issues), help maintain the positive results following a PR programme and promote patients' adherence to a more active lifestyle through physical activity (tele)coaching. Despite the accelerated use of digital health to deliver PR during the coronavirus disease 2019 pandemic, there are still several factors that contribute to the resistance to the adoption of digital health, such as the lack of evidence on its effectiveness, low acceptability by patients and healthcare professionals, concerns about implementation and maintenance costs, inequalities in access to the internet and technological devices, and data protection issues. Nevertheless, the trend towards reducing technology costs and the higher availability of digital devices, as well as the greater ease and simplicity of use of devices, enhance the opportunities for future development of digitally enabled PR interventions. This narrative review aims to examine the current evidence on the role of digital health in the context of PR, including strengths and weaknesses, and to determine possible threats and opportunities, as well as areas for future work.

High-intensity interval training improves the outcomes of patients with chronic obstructive pulmonary disease: A meta-analysis of randomized controlled trials

BACKGROUND

Pulmonary exercise is an important part in the treatment of chronic obstructive pulmonary disease (COPD). We aimed to evaluate the effects and safety of high-intensity interval training (HIIT) in patients with COPD, to provide insights to the COPD treatment and care.

METHODS

Two investigators searched PubMed, Medline, Embase, web of Science, Cochrane library, China National Knowledge Infrastructure (CNKI), Wanfang, and Weipu databases up to Sept 15, 2022 for randomized controlled trials (RCTs) on the effects and safety of HIIT for COPD patients. RevMan5.3 software was used for statistical analysis.

RESULTS

A total of 20 RCTs involving 962 COPD patients were finally included. 514 patients underwent HIIT interventions. Meta-analysis showed that HIIT increased the peak oxygen consumption (SMD = 0.30, 95%CI:0.14-0.46), peak minute ventilation (SMD = 0.26, 95%CI: 0.05-0.47), peak work rate (SMD = 0.34, 95%CI: 0.17-0.51), 6-min walking distance (SMD = 0.39, 95%CI: 0.23-0.55) in COPD patients (all P < 0.05). HIIT improved the quality of life (SMD = 0.30, 95%CI: 0.06-0.54) and reduced the dyspnea (SMD = -0.27, 95%CI: -0.51∼-0.03) in COPD patients (all P < 0.05). There were no significant differences in the forced expiratory volume in 1 s/forced vital capacity (SMD = 0.28, 95%CI: -0.01-0.56) and St. George's Respiratory Questionnaire score (SMD = -0.35, 95%CI: -0.73-0.03) between HIIT and control group (all P > 0.05). There was no publication bias analyzed by the Egger test and funnel plots (all P > 0.05).

CONCLUSIONS

HIIT may be beneficial to improve the pulmonary function, exercise capacity and quality of life of patients with COPD, which is worthy of clinical promotion for COPD treatment and care.

COPD: Providing the right treatment for the right patient at the right time

Chronic Obstructive Pulmonary Disease (COPD) is a common disease associated with significant morbidity and mortality that is both preventable and treatable. However, a major challenge in recognizing, preventing, and treating COPD is understanding its complexity. While COPD has historically been characterized as a disease defined by airflow limitation, we now understand it as a multi-component disease with many clinical phenotypes, systemic manifestations, and associated co-morbidities. Evidence is rapidly emerging in our understanding of the many factors that contribute to the pathogenesis of COPD and the identification of "early" or "pre-COPD" which should provide exciting opportunities for early treatment and disease modification. In addition to breakthroughs in our understanding of the origins of COPD, we are optimizing treatment strategies and delivery of care that are showing impressive benefits in patient-centered outcomes and healthcare utilization. This special issue of Respiratory Medicine, "COPD: Providing the Right Treatment for the Right Patient at the Right Time" is a summary of the proceedings of a conference held in Stresa, Italy in April 2022 that brought together international experts to discuss emerging evidence in COPD and Pulmonary Rehabilitation in honor of a distinguished friend and colleague, Claudio Ferdinando Donor (1948-2021). Claudio was a true pioneer in the field of pulmonary rehabilitation and the comprehensive care of individuals with COPD. He held numerous leadership roles in in the field, provide editorial stewardship of several respiratory journals, authored numerous papers, statement and guidelines in COPD and Pulmonary Rehabilitation, and provided mentorship to many in our field. Claudio's most impressive talent was his ability to organize spectacular conferences and symposia that highlighted cutting edge science and clinical medicine. It is in this spirit that this conference was conceived and planned. These proceedings are divided into 4 sections which highlight crucial areas in the field of COPD: (1) New concepts in COPD pathogenesis; (2) Enhancing outcomes in COPD; (3) Non-pharmacologic management of COPD; and (4) Optimizing delivery of care for COPD. These presentations summarize the newest evidence in the field and capture lively discussion on the exciting future of treating this prevalent and impactful disease. We thank each of the authors for their participation and applaud their efforts toward pushing the envelope in our understanding of COPD and optimizing care for these patients. We believe that this edition is a most fitting tribute to a dear colleague and friend and will prove useful to students, clinicians, and researchers as they continually strive to provide the right treatment for the right patient at the right time. It has been our pleasure and a distinct honor to serve as editors and oversee such wonderful scholarly work.

Transition to a virtual model of physiotherapy and exercise physiology in response to COVID-19 for people in a rural Australia: Is it a viable solution to increase access to allied health for rural populations?

Virtual healthcare has the potential to increase access to allied health for people living in rural areas, but challenges in delivery of such models have been reported. The COVID-19 pandemic provided an opportunity for a rural practice of physiotherapists and exercise physiologists to transition service delivery to a virtual model of care which utilised a combination of phone, video, an exercise app and/or paper handouts. This study aimed to evaluate the uptake and outcomes from virtual delivery of allied health services, and to describe patient and clinician experiences of the virtual model of care. A parallel convergent mixed methods study was conducted. De-identified data from patients who were offered the virtual service between 15 March 2020 and 30 September 2020 were extracted from the database of the rural practice, as were data from patients attending the practice in-person during the same time in 2019 to serve as a historical comparison. De-identified data from a monthly survey tracking clinician experiences of delivering care virtually was also obtained from the practice. Quantitative data were presented descriptively. Between-group differences were compared using independent samples t-tests, and within-group longitudinal changes compared using paired t-tests. Semi-structured interviews were conducted among a purposive sample of patients using the virtual service, and focus groups conducted among clinicians providing this model of care. Qualitative data were recorded and transcribed verbatim, then thematic analysis conducted. During the study period, the practice delivered 4% (n = 242) consultations virtually. Thirty-seven of the 60 patients (62%) using the virtual service were new referrals. Patients attended fewer sessional appointments virtually and a smaller proportion of patients reported high satisfaction with virtual care, compared to those who received in-person care the previous year (p < .05). Clinician confidence in delivering virtual care did not change significantly over time (p>.05), though clinicians not providing virtual care in a given month perceived their lower confidence than those who did provide virtual care (p < .05). Five themes influencing the success of virtual allied health provision emerged from patient interviews and clinician focus groups: adaptation of program elements for virtual delivery, conduct of virtual treatment, clinician flexibility, patient complexity and communication. The theme of communication influenced all the other themes. Virtual healthcare is a potential solution to address lack of access to allied health practitioners in rural areas, but may not suit all patients. Establishing a therapeutic relationship and ensuring people have access to adequate resources prior to virtual care delivery will optimise successful adoption of virtual care models. A hybrid model incorporating limited in-person consultations with virtual consultations appears a more viable option.

Relationship between serum Th1/Th2 imbalance and depression in elderly patients with COPD and its clinical implications

BACKGROUND

Chronic obstructive pulmonary disease (COPD) causes organic damage as well as anxiety, depression, fear, and other psychological disorders, which seriously affect the quality of life and prognosis of patients and cause a huge economic burden to the family and society.

OBJECTIVE

The aim of this study was to investigate the correlation between an imbalance of serum Th1/Th2 indicators and psychiatric depression in elderly patients with COPD and analyze its implications for clinical management.

METHODS

From January 2018 to May 2022, 120 elderly patients with COPD treated at our hospital were categorized into two groups based on the self-rating depression scale (SDS): COPD with depression (SDS score ⩾ 50) and COPD alone (SDS score < 50). Blood gas analysis, pulmonary function, and serum Th1/Th2 index were determined. Receiver operating characteristic (ROC) curves were analyzed to explore the diagnostic value of serum Th1/Th2 ratios for COPD complicated by depression.

RESULTS

Compared with the group without depression, the partial pressure of carbon dioxide and COPD assessment test scores were significantly higher, and the oxygenation index, forced expiratory volume in one second (FEV1), and percent predicted FEV1 were significantly lower in the COPD with depression group (P< 0.05). Interleukin (IL)-1β, IL-2, IL-6, IL-8, IL-10, and tumor necrosis factor-α (TNF-α) were significantly higher in the COPD with depression group than in the group without depression (P< 0.05). Logistic regression analysis indicated that the imbalance of serum IL-1β, IL-2, IL-6, IL-8, IL-10, and TNF-α was a risk factor for mental depression in elderly patients with COPD. When comparing prognostic indices, the interval before the first onset of clinically noticeable deterioration (CID-C) in the COPD with depression group was noticeably shorter than that in the COPD without depression group; the incidence of CID-C within 6 months was noticeably higher in the COPD with depression group than in the group without depression.

CONCLUSION

Elderly patients with COPD and depression had reduced pulmonary function and higher serum Th1/Th2 levels, and an imbalance in serum Th1/Th2 indicators was a potential risk factor for depression. Moreover, elderly patients with COPD and depression were at a higher risk of disease progression and had a worse prognosis. Thus, an imbalance in serum Th1/Th2 indicators is a potential prognostic factor for evaluating depression in patients with COPD.

Perceived Autonomy Support in Telerehabilitation by People With Chronic Respiratory Disease: A Mixed Methods Study

BACKGROUND

Autonomy-supportive health environments can assist patients in achieving behavior change and can influence adherence positively. Telerehabilitation may increase access to rehabilitation services, but creating an autonomy-supportive environment may be challenging.

RESEARCH QUESTION

To what degree does telerehabilitation provide an autonomy-supportive environment? What is the patient experience of an 8-week telerehabilitation program?

STUDY DESIGN AND METHODS

Individuals undertaking telerehabilitation or center-based pulmonary rehabilitation within a larger randomized controlled equivalence trial completed the Health Care Climate Questionnaire (HCCQ; short form) to assess perceived autonomy support. Telerehabilitation participants were invited 1:1 to undertake semistructured interviews. Interviews were transcribed verbatim and coded thematically to identify major themes and subthemes.

RESULTS

One hundred thirty-six participants (n = 69 telerehabilitation) completed the HCCQ and 30 telerehabilitation participants (42%) undertook interviews. HCCQ summary scores indicated that participants strongly agreed that the telerehabilitation environment was autonomy supportive, which was similar to center-based participants (HCCQ summary score, P = .6; individual HCCQ items, P ≥ .3). Telerehabilitation interview data supported quantitative findings identifying five major themes, with subthemes, as follows: (1) making it easier to participate in pulmonary rehabilitation, because telerehabilitation was convenient, saved time and money, and offered flexibility; (2) receiving support in a variety of ways, including opportunities for peer support and receiving an individualized program guided by expert staff; (3) internal and external motivation to exercise as a consequence of being in a supervised group, seeing results for effort, and being inspired by others; (4) achieving success through provision of equipment and processes to prepare and support operation of equipment and technology; and (5) after the rehabilitation program, continuing to exercise, but dealing with feelings of loss.

INTERPRETATION

Telerehabilitation was perceived as an autonomy-supportive environment, in part by making it easier to undertake pulmonary rehabilitation. Support for behavior change, understanding, and motivation were derived from clinicians and patient-peers. The extent to which autonomy support translates into ongoing self-management and behavior change is not clear.

A Telerehabilitation Program for Maintaining Functional Capacity in Patients With Chronic Lung Diseases During a Period of COVID-19 Social Isolation: Quasi-Experimental Retrospective Study

BACKGROUND

Pulmonary diseases represent a great cause of disability and mortality in the world, and given the progression of these pathologies, pulmonary rehabilitation programs have proven to be effective for people with chronic respiratory diseases. During the COVID-19 pandemic, telerehabilitation has become an alternative for patients with such diseases.

OBJECTIVE

The aim of this study was to compare the outcomes (ie, functional capacity and quality of life) of telerehabilitation to those of usual care among patients who previously participated in face-to-face pulmonary rehabilitation programs.

METHODS

We conducted a quasi-experimental retrospective study from April 2020 to August 2021. A total of 32 patients with chronic lung diseases were included and divided into the control and intervention groups. The intervention group performed telerehabilitation synchronously twice per week and was supervised by a physical therapist during breathing, strengthening, and aerobic exercises. Changes in the degree of dyspnea and leg discomfort were assessed based on changes in Borg scale scores. The control group did not perform any activities during the period of social isolation. Functional capacity was assessed with the 6-minute walk test, and quality of life was assessed with the Medical Outcomes Study 36-item Short Form Health Survey.

RESULTS

The telerehabilitation group's mean 6-minute walk distance decreased by 39 m, while that of the control group decreased by 120 m. There was a difference of 81 m between the groups' mean 6-minute walk distances (P=.02). In relation to the quality of life, telerehabilitation was shown to improve the following two domains: social functioning and mental health.

CONCLUSIONS

Telerehabilitation programs for patients with chronic lung diseases can ease the deleterious effects of disease progression, be used to maintain functional capacity, and improve aspects of quality of life.

Sleep Quality and Self-Reported Symptoms of Anxiety and Depression Are Associated with Physical Activity in Patients with Severe COPD

Sleep quantity, quality and symptoms of depression or anxiety potentially affect the level of daily physical activity (PAL) and plausibly counteracts benefits from pulmonary rehabilitation programs. Their collective impact on PAL is sparsely investigated, particularly in patients with severely progressed chronic obstructive pulmonary disease (COPD). Aim: To investigate if sleep quantity, quality and symptoms from self-reported hospital anxiety and depression scores (HADS) are associated with PAL. Methods: In this exploratory cross-sectional study data were analysed from 148 participants with COPD; GOLD grade II-IV; GOLD group B to D (52% female, mean 69.7 ± SD of 8.4 years, FEV1% predicted 33.6 ± 10.9, 6MWD 327 ± 122 m, CAT 20 ± 7 points), eligible for conventional outpatient hospital-based pulmonary rehabilitation. Participants had sleep and PAL measured 24 h per day for five consecutive days with an activPAL monitor. Adjusted negative binomial regression was applied to investigate the associations with PAL. Results: Participants walked median (25th, 75th percentile) of 2358 (1325.75; 3822.25) steps per day and 14% walked >5000 steps per day on average. Time in bed (TIB) were a median (25th, 75th percentile) of 8.3 (7.1; 9.7) hours and numbers of nocturnal sleeping bouts (NSB) were 1.5 (0.8; 3), Anxiety (HADS-A) and depression (HADS-D) scores were median (25th, 75th percentile) of 5 (3; 8) points and 3 (2; 6) points, respectively, whereof 29% (HADS-A) and 15% (HADS-D) reported scores ≥8 points indicating significant symptoms. The fully adjusted rate ratio (RR) for steps per day for TIB (hours) [RR 0.97 (95% CI: 0.92; 1.02)], NSB (numbers) [RR 1.02 (95% CI: 0.97; 1.07)] were not significantly associated with number of steps per day, while there was a significantly association with number of steps per day for HADS-A [RR 1.04 (95% CI: 1.01; 1.07)] and HADS-D [RR 0.95 (95% CI: 0.91; 0.99)]. Conclusion: This exploratory cross-sectional study found a statistically significant association between HADS-A and HADS-D with numbers of steps per day in patients with severe COPD.

Home based pulmonary tele-rehabilitation under telemedicine system for COPD: a cohort study

Background

Pulmonary tele-rehabilitation can improve adherence to pulmonary rehabilitation. However, there are few reports on home based pulmonary tele-rehabilitation. We assessed the effectiveness of home based pulmonary tele-rehabilitation under telemedicine system in patients with chronic obstructive pulmonary disease (COPD).

Methods

This cohort study enrolled 174 patients with COPD who received home based pulmonary tele-rehabilitation under telemedicine system. The follow-up time was 12 weeks. Patients were grouped according to pulmonary rehabilitation weeks, number of rehabilitation times and total duration time, and when these three data were inconsistent, the two lowest values were grouped: control group (total rehabilitation weeks < 1 week, total number of rehabilitation times < 5, total duration time < 150 min, n = 46), pulmonary rehabilitation group 1 (PR-1) (1 week ≤ rehabilitation weeks < 4 weeks, 5 ≤ total number of rehabilitation times < 20, 150 min ≤ total duration time  < 1200 min, n = 31), pulmonary rehabilitation group 2 (PR-2) (4 weeks ≤ rehabilitation weeks < 8 weeks, 20 ≤ total number of rehabilitation times < 40, 600 min ≤ total duration time < 2400 min, n = 23), pulmonary rehabilitation group 3 (PR-3) (8 weeks ≤ rehabilitation weeks < 12 weeks, 40 ≤ total number of rehabilitation times < 60, 1200 min ≤ total duration time < 3600 min, n = 40) and pulmonary rehabilitation group 4 (PR-4) (rehabilitation weeks = 12 weeks, total number of rehabilitation times = 60, total duration time = 3600 min, n = 34). The clinical data before and after rehabilitation were collected and evaluated, including dyspnea symptoms, 6-min walk distance (6MWD), diaphragmatic mobility, anxiety and depression.

Results

There was no significance difference between control group and PR-1 group. PR-2 group after rehabilitation had significantly decreased CAT and HAMA scores than control (P < 0.05). Compared with control, PR-3 group and PR-4 group after rehabilitation had significantly higher 6MWD and diaphragmatic motility during deep breathing, but significantly lower CAT score, mMRC score, HAMA score, and HAMD score (P < 0.05). Compared with before pulmonary rehabilitation, in PR-3 and PR-4 groups, the 6MWD and the diaphragmatic motility during deep breathing were significantly higher, while CAT score, mMRC score, HAMA score, and HAMD score (for PR-4 only) were significantly lower after pulmonary rehabilitation (P < 0.05). There was no significant difference between PR-3 group and PR-4 group (P > 0.05). In the 12-week pulmonary rehabilitation program, patients who completed at least 8 weeks, namely those in the PR-3 and PR-4 groups, accounted for 42.5% of the total number. Education, income and response rate to telemedicine system reminders were the main risk factors associated with home based pulmonary tele-rehabilitation.

Conclusions

Home based pulmonary tele-rehabilitation under telemedicine system for more than 8 weeks can significantly improve the dyspnea symptoms, 6MWD, diaphragmatic mobility during deep breathing, and negative emotions of patients with moderate to severe stable COPD.

Photovoice exploration of physical activity norms and values among rural and remote pulmonary rehabilitation participants in British Columbia, Canada

PURPOSE

Individuals with chronic obstructive pulmonary disease (COPD) engage in less physical activity compared to the general population, which can lead to worsened symptoms. In pulmonary rehabilitation (PR) programs, participants learn strategies to complete activities more easily. For such strategies to be effective, however, PR clinicians must understand their clients' activity values and practices within their geocultural contexts. In this qualitative study, our aim was to explore physical activity norms and values among people with COPD living in remote and rural locations, using Photovoice methodology.

MATERIALS AND METHODS

We recruited 12 participants from rural PR sites in British Columbia, Canada. During two distinct seasons (winter and summer), participants photographed meaningful activities then completed semi-structured interviews. We analyzed transcripts using a three-step hermeneutic method, which revealed three themes.

RESULTS

Participants discussed feeling conflicted regarding their COPD symptoms and physical activity, as difficulties in activity engagement cause stress, but remaining active also fosters a sense of purpose and well-being. Meanwhile, participants' activities are inextricably linked to their rural, remote, and seasonal environment.

CONCLUSIONS

Our study provides insight into how people with COPD resiliently engage in activities in a rural environment with distinct weather variations. Findings highlight the importance of considering individual factors when recommending activities in PR programs.Implications for rehabilitationAlthough people with chronic lung disease often encounter difficulty and stress in completing their daily activities, they both recognize the importance of and derive great personal meaning from remaining active.The unique social, geographical, physical, and climatic environments of rural and remote dwelling people with chronic lung disease can both enable and challenge their activity engagement.Pulmonary rehabilitation (PR) programs and clinicians must situate their activity recommendations within the geographic contexts of their clients - which can vary across the seasons.Support for participants' mental health is a vital aspect of PR.

Characteristics, Components, and Efficacy of Telerehabilitation Approaches for People with Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-Analysis

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is at the top of the list of non-communicable diseases with related rehabilitation needs. Digital medicine may provide continuative integrated intervention, overcoming accessibility and cost barriers.

METHODS

We systematically searched for randomized controlled trials on telerehabilitation (TR) in people with COPD to profile the adopted TR strategies, focusing on TR models and the main rehabilitation actions: monitoring and assessment, decision, and feedback. Additionally, a meta-analysis was run to test the TR effect on functional capacity, dyspnea, and quality of life compared to no intervention (NI) and conventional intervention (CI).

RESULTS

Out of the 6041 studies identified, 22 were eligible for the systematic review, and 14 were included in the meta-analyses. Results showed a heterogeneous scenario in terms of the TR features. Furthermore, only a small group of trials presented a comprehensive technological kit. The meta-analysis highlighted a significant effect of TR, especially with the asynchronous model, on all outcomes compared to NI. Moreover, a non-inferiority effect of TR on functional capacity and quality of life, and a superiority effect on dyspnea compared to CI were observed. Finally, the studies suggested a high rate of TR adherence and high safety level.

CONCLUSIONS

TR is an effective strategy to increase and maintain functional capacity, breath, and quality of life in people with COPD. However, a consensus on the essential elements and features of this approach needs to be defined, and the effect of long-term maintenance merits further investigation.

Efficacy of Different Types of Physical Activity Interventions on Exercise Capacity in Patients with Chronic Obstructive Pulmonary Disease (COPD): A Network Meta-Analysis

AIM

A network meta-analysis (NMA) was performed to determine the effects on the exercise capacity, measured by the 6 MWT, of patients with COPD of (i) different physical activity interventions and (ii) supervised or unsupervised programs.

METHODS

A literature search was carried out from inception to April 2022. Randomized controlled trials of the effectiveness of physical activity on exercise capacity in patients with COPD were included. The risk of bias was assessed using the Cochrane Risk of Bias (RoB 2.0) tool, and the Grading of Recommendations, Assessment, Development, and Evaluation tool (GRADE) was used to assess the quality of the evidence. A pairwise meta-analysis for direct and indirect effects was carried out.

RESULTS

A total of 41 studies were included in this NMA. The highest effects were for urban training pulmonary rehabilitation (PR) programs (ES, 1.50; 95% CI: 0.46 and 2.55) versus the control group. For supervised and unsupervised PR and home-based PR programs, the highest effects were found for supervised PR (ES, 0.85; 95% CI: 0.46 to 1.23) versus the control group.

CONCLUSIONS

PR implemented with urban circuit training should be considered the most effective strategy to improve exercise capacity in patients with COPD. Supervision of the programs improves exercise capacity.

Exercise Capacity in Patients With Chronic Obstructive Pulmonary Disease Treated With Tele-Yoga Versus Tele-Pulmonary Rehabilitation: A Pilot Validation Study

Background In chronic obstructive pulmonary disease (COPD), pulmonary rehabilitation (PR) is an integral component of the non-pharmacological management of COPD. Yoga has proven to be beneficial in COPD, although well-designed comparative studies between the two modalities are lacking. This pilot study aims to compare these two modalities delivered as supervised tele-intervention. Methods The outpatient department (OPD) of a tertiary hospital recruited consenting, consecutive, inclusion-eligible COPD participants who were randomly assigned to intervention and control arms of 30 patients each. The intervention arm received a 45-minute tele-yoga therapy module (T-YT) validated by content validity ratio (CVR), computed using Lawshe's methodology and responses from 24 yoga specialists. The control arm received a 45-minute standardized tele-pulmonary rehabilitation session (T-PR). T-YT and T-PR were both managed through an online portal. Exercise capacity as measured by the six-minute walk distance (6MWD), symptom score (COPD assessment test [CAT], modified medical research council [mMRC]), forced expiratory volume in one second (FEV1%), quality of life (QoL) scores, St. George respiratory questionnaire (SGRQ), depression and anxiety scores (patient health questionnaire [PHQ-9] and generalized anxiety disorder scale [GAD-7] scores), were recorded at baseline and at the end of three months. Results 6MWD, symptom scores, SGRQ, PHQ-9, and GAD-7 all improved significantly from baseline within each group, but there was no statistically significant difference between the groups. FEV1% did not differ significantly between or among groups. This study shows T-YT module can be a reasonable substitute for T-PR in patients with COPD. Conclusions T-YT is beneficial in patients of COPD in terms of exercise capacity, symptom scores, and depression and anxiety scores and can be a reasonable alternative to T-PR.

Evaluating Virtual and Inpatient Pulmonary Rehabilitation Programs for Patients with COPD

Chronic obstructive pulmonary disease (COPD) is an increasingly frequent disorder that is likely to become the third leading cause of morbidity worldwide. It significantly degrades the quality of life of patients affected and poses a significant financial burden to the healthcare systems providing treatment and rehabilitation. Consequently, our study’s purpose was to compare conventional inpatient pulmonary rehabilitation (PR) with virtual (online) PR using a mobile phone application. During a three-month period, two groups of patients followed the research protocol by participating in a pulmonary rehabilitation program administered and supervised by a physical therapist five times per week. A number of respiratory variables were examined before and after the test. At the end of the study period, a total of 72 patients completed the rehabilitation in the inpatient group, respectively 58 in the online group. It was observed that post-test comparison between patients undergoing the traditional and online rehabilitation methods did not show any significant differences. However, the calculated mean differences between pre-test and post-test results were significantly higher in favor of the virtual method. The most significant variations were encountered in maximal inspiratory pressure (MIP) (6.6% vs. 8.5%, p-value < 0.001), 6-min walking test (6MWT) (6.7% vs. 9.4%, p-value < 0.001), and COPD assessment test (CAT) values (4.8 vs. 6.2, p-value < 0.001), respectively. However, the maximal expiratory pressure (MEP) variation was significantly higher in patients undergoing the traditional rehabilitation method, from an average of 4.1% to 3.2% (p-value < 0.001). In this preliminary study, the online pulmonary rehabilitation program proved non-inferiority to the traditional method, with significantly better results in several measurements. Additional studies using larger cohorts of patients and longer exposure to the online rehabilitation program are required to validate these findings.

Effectiveness of home-based pulmonary rehabilitation: systematic review and meta-analysis

INTRODUCTION

Despite proven effectiveness for people with chronic respiratory diseases, practical barriers to attending centre-based pulmonary rehabilitation (centre-PR) limit accessibility. We aimed to review the clinical effectiveness, components and completion rates of home-based pulmonary rehabilitation (home-PR) compared to centre-PR or usual care.

METHODS AND ANALYSIS

Using Cochrane methodology, we searched (January 1990 to August 2021) six electronic databases using a PICOS (population, intervention, comparison, outcome, study type) search strategy, assessed Cochrane risk of bias, performed meta-analysis and narrative synthesis to answer our objectives and used the Grading of Recommendations, Assessment, Development and Evaluations framework to rate certainty of evidence.

RESULTS

We identified 16 studies (1800 COPD patients; 11 countries). The effects of home-PR on exercise capacity and/or health-related quality of life (HRQoL) were compared to either centre-PR (n=7) or usual care (n=8); one study used both comparators. Compared to usual care, home-PR significantly improved exercise capacity (standardised mean difference (SMD) 0.88, 95% CI 0.32-1.44; p=0.002) and HRQoL (SMD -0.62, 95% CI -0.88--0.36; p<0.001). Compared to centre-PR, home-PR showed no significant difference in exercise capacity (SMD -0.10, 95% CI -0.25-0.05; p=0.21) or HRQoL (SMD 0.01, 95% CI -0.15-0.17; p=0.87).

CONCLUSION

Home-PR is as effective as centre-PR in improving functional exercise capacity and quality of life compared to usual care, and is an option to enable access to pulmonary rehabilitation.

Feasibility of a pulmonary rehabilitation programme for patients with symptomatic chronic obstructive pulmonary disease in Georgia: a single-site, randomised controlled trial from the Breathe Well Group

OBJECTIVES

To assess the feasibility of delivering a culturally tailored pulmonary rehabilitation (PR) programme and conducting a definitive randomised controlled trial (RCT).

DESIGN

A two-arm, randomised feasibility trial with a mixed-methods process evaluation.

SETTING

Secondary care setting in Georgia, Europe.

PARTICIPANTS

People with symptomatic spirometry-confirmed chronic obstructive pulmonary disease recruited from primary and secondary care.

INTERVENTIONS

Participants were randomised in a 1:1 ratio to a control group or intervention comprising 16 twice-weekly group PR sessions tailored to the Georgian setting.

PRIMARY AND SECONDARY OUTCOME MEASURES

Feasibility of the intervention and RCT were assessed according to: study recruitment, consent and follow-up, intervention fidelity, adherence and acceptability, using questionnaires and measurements at baseline, programme end and 6 months, and through qualitative interviews.

RESULTS

The study recruited 60 participants (as planned): 54 (90%) were male, 10 (17%) had a forced expiratory volume in 1 second of ≤50% predicted. The mean MRC Dyspnoea Score was 3.3 (SD 0.5), and mean St George's Respiratory Questionnaire (SGRQ) 50.9 (SD 17.6). The rehabilitation specialists delivered the PR with fidelity. Thirteen (43.0%) participants attended at least 75% of the 16 planned sessions. Participants and rehabilitation specialists in the qualitative interviews reported that the programme was acceptable, but dropout rates were high in participants who lived outside Tbilisi and had to travel large distances. Outcome data were collected on 63.3% participants at 8 weeks and 88.0% participants at 6 months. Mean change in SGRQ total was -24.9 (95% CI -40.3 to -9.6) at programme end and -4.4 (95% CI -12.3 to 3.4) at 6 months follow-up for the intervention group and -0.5 (95% CI -8.1 to 7.0) and -8.1 (95% CI -16.5 to 0.3) for the usual care group at programme end and 6 months, respectively.

CONCLUSIONS

It was feasible to deliver the tailored PR intervention. Approaches to improve uptake and adherence warrant further research.

Telerehabilitation as a Form of Pulmonary Rehabilitation in Chronic Lung Disease: A Systematic Review

Introduction: Tele-rehabilitation is increasingly used to deliver pulmonary rehabilitation. The aim of this systematic review was to compare the effect between tele-pulmonary rehabilitation and classical supervised pulmonary rehabilitation. Method: Three databases were analysed (PubMed, PEDro, Scopus). The selection and evaluation of studies followed the PRISMA guidelines. The risk of bias was evaluated using the PEDro Scale. Results: From the initial selection (n = 245), ten studies were retrieved, including from 10 to 67 patients. All but two (IPF) included patients with COPD. Based on the FEV1, patients with COPD were mainly categorised as moderate and severe. The teleactivities were heterogenous in terms of proposed exercises and way of settings and often not in agreement with the guidelines about pulmonary rehabilitation. Despite this, the effects of the interventions were globally positive on functional exercise capacity, quality of life, anxiety and depression, and impact of COPD on personal life but not on dyspnoea. The PEDro scores varied from 4 to 8. The adherence was higher than 80% when supervision during the exercise was included. Conclusion: This review demonstrated that the telerehabilitation is safe and well accepted by the patients, and could be considered as one option of classical pulmonary rehabilitation to improve the functional exercise capacity, quality of life, anxiety and depression, and the impact of COPD on personal’s life. This conclusion cannot be extrapolated to the other chronic lung diseases due to the lack of data.
