Using a smartphone application maintains physical activity following pulmonary rehabilitation in patients with COPD: a randomised controlled trial

Beyond pulmonary rehabilitation: can the PICk UP programme fill the gap? A randomised trial in COPD

INTRODUCTION AND OBJECTIVES

Pulmonary rehabilitation (PR) is a fundamental intervention to manage COPD, however, maintaining its benefits is challenging. Engaging in physical activity might help to prolong PR benefits. This study assessed the efficacy and effectiveness of a personalised community-based physical activity programme to sustain physical activity and other health-related PR benefits, in people with COPD.

MATERIALS AND METHODS

This was a multicentre, assessor blinded, randomised controlled trial. Following 12-weeks of PR, people with COPD were assigned to a six-months personalised community-based physical activity programme (experimental group), or to standard care (control group). Physical activity was assessed via: time spent in moderate to vigorous physical activities per day (primary outcome measure), steps/day and the brief physical activity assessment tool. Secondary outcomes included sedentary behaviour, functional status, peripheral muscle strength, balance, symptoms, emotional state, health-related quality of life, exacerbations and healthcare utilization. Assessments were performed immediately post-PR and after three- and six-months. Efficacy and effectiveness were evaluated using intention-to-treat and per-protocol analysis with linear mixed models.

RESULTS

Sixty-one participants (experimental group: n = 32; control group: n = 29), with balanced baseline characteristics between groups (69.6 ± 8.5 years old, 84 % male, FEV1 57.1 ± 16.7 %predicted) were included. Changes in all physical activity outcomes and in one-minute sit-to-stand were significantly different (P < 0.05) between groups at the six-month follow-up. In the remaining outcomes there were no differences between groups.

CONCLUSIONS

The community-based physical activity programme resulted in better physical activity levels and sit-to-stand performance, six-months after completing PR, in COPD. No additional benefits were observed for other secondary outcomes.

A Smartphone App Self-Management Program for Chronic Obstructive Pulmonary Disease: Randomized Controlled Trial of Clinical Outcomes

BACKGROUND

Chronic obstructive pulmonary disease (COPD) negatively impacts clinical health outcomes, resulting in frequent exacerbations, increased hospitalizations, reduced physical activity, deteriorated quality of life, and diminished self-efficacy. Previous studies demonstrated that a self-management program tailored for adults with COPD improves self-management decisions, resulting in a positive effect on clinical health outcomes. Limitations of these studies include issues regarding heterogeneity among interventions used, patient population characteristics, outcome measures, and longitudinal studies. Limited studies focused on the use of a comprehensive self-management program using a smartphone app for adults with COPD over 12 months.

OBJECTIVE

This study aimed to explore the effectiveness of a smartphone app self-management program and monthly phone calls compared with standard respiratory outpatient care on clinical health outcomes in adults with COPD.

METHODS

This was a 3-arm parallel pilot randomized controlled trial (RCT) that included 92 participants. Participants were randomized into intervention arm 1, which included a self-management smartphone app and monthly phone calls (n=31); intervention arm 2, which included a self-management smartphone app (n=31); and arm 3, which was standard respiratory outpatient care (n=30). All arms received standard respiratory outpatient care. The primary outcome was a binary indicator equal to 1 if participants reported attendance to a general practitioner (GP) and or a hospital setting as a result of an exacerbation and 0 otherwise. This indicator was recorded at 6 months and 12 months from the baseline. Secondary outcomes included engagement, breathlessness, physical activity, health-related quality of life, and self-efficacy.

RESULTS

There was a statistically significant difference (P=.03), indicating fewer exacerbations in the intervention arm 2 compared with the control arm at 6 months in the hospital setting. The intervention arms had a statistically significant difference indicating a lower risk of developing an exacerbation at 6 months in both the GP (P=.01) and hospital setting (P=.006) compared to the control arm. Furthermore, intervention arm 1 demonstrated a statistically significant difference in exercise capacity at 6 and 12 months (P=.02 and P=.03). The intervention arm 2 illustrated a statistically significant difference in step count (P=.009) compared to the control arm. The majority of participants (60%, 33/55) used the app over the 12-month period.

CONCLUSIONS

This study demonstrated that a smartphone app self-management program had a positive effect on clinical health outcomes for participants with COPD in comparison to standard respiratory outpatient care. This study illustrated benefits such as reduced exacerbations resulting in fewer hospitalizations, improved exercise capacity, and physical activity among the intervention arms. This was a single-center study, which was limited in power to demonstrate significant effects on all measured outcomes but paves the way for a larger, fully powered multicenter trial exploring the effect of a smartphone app self-management program on clinical health outcomes in adults with COPD.

Efficacy of an Intelligent and Integrated Older Adult Care Model on Quality of Life Among Home-Dwelling Older Adults: Randomized Controlled Trial

BACKGROUND

Integrated care models enhanced by the clinical decision support system offer innovative approaches to managing the growing global burden of older adult care. However, their efficacy remains uncertain.

OBJECTIVE

This study aimed to evaluate the efficacy of an intelligent and integrated older adult care model, termed the SMART (Sensors and scales [receptor], a Mobile phone autonomous response system [central nervous system in the spinal cord], a Remote cloud management center [central nervous system in the brain], and a Total care system [effector]) system, in improving the quality of life (QOL) for home-dwelling older adults.

METHODS

In this stratified randomized controlled trial, we consecutively recruited older adults aged 65 years or older from November 1, 2020, to December 31, 2020. Eligible participants were randomly allocated 1:1 to either the SMART group, receiving routine discharge instructions and personalized integrated care interventions across 11 domains (decreased or lost self-care ability, falls, delirium, dysphagia, incontinence, constipation, urinary retention, cognitive decline, depression, impaired skin integrity, and common diseases) generated by the SMART system, or the usual care group, receiving only routine discharge instructions. The intervention lasted for 3 months. The primary end point was the percent change in QOL from baseline to the 3-month follow-up, assessed using the World Health Organization Quality of Life Instrument - Older Adults Module. Secondary end points included functional status at the 3-month follow-up and percent changes in health self-management ability, social support, and confidence in avoiding falling from baseline to the 3-month follow-up. Data were analyzed following the intention-to-treat principle, using covariance or logistic regression models, as appropriate. Subgroup and sensitivity analyses were conducted to assess result consistency and robustness.

RESULTS

In total, 94 participants were recruited, with 48 assigned to the SMART group. The personalized and integrated care by the SMART system significantly improved the QOL among the older adults, with an estimated intervention difference of 11.97% (95% CI 7.2%-16.74%, P<.001), and social support and health self-management ability as well, with estimated intervention differences of 6.75% (95% CI 3.19%-10.3%, P<.001) and 4.95% (95% CI 0.11%-10%, P=.003), respectively, while insignificantly improving in the Modified Falls Efficacy Scale score. Similarly, the SMART system had a 66% reduction in instrumental activities of daily living disability (odds ratio [OR] 0.34, 95% CI 0.11-0.83, P=.02). However, the SMART system did not significantly affect activities of daily living disability or the Modified Falls Efficacy Scale score. The subgroup and sensitivity analyses confirmed the robustness of the findings.

CONCLUSIONS

The personalized and integrated older adult care by the SMART system demonstrated significant efficacy in improving QOL, health self-management ability, and social support, while reducing instrumental activities of daily living disability among home-dwelling older adults.

Core characteristics, and effectiveness of mobile health interventions on dyspnoea and quality of life in older persons with chronic obstructive pulmonary disease: A systematic review and meta-analysis of randomised controlled trials

AIM

To systematically review the core characteristics, and effectiveness of mobile health interventions (MHIs) on dyspnoea and quality of life (QoL) in older persons with chronic obstructive pulmonary disease (COPD).

METHODS

A comprehensive search was conducted from inception to 21 February 2023 in Chinese and English databases, with an updated search performed on 30 April 2024. Randomised controlled trials (RCTs) involving MHIs with four core functions - customisation, self-monitoring, alerts, and goal-setting - in older persons with COPD were included. Two reviewers independently identified the core characteristics of MHIs using the Template for Intervention Description and Replication (TIDieR) checklist. The Cochrane risk-of-bias tool and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach were used to assess the methodological quality of RCTs and the overall quality of evidence.

RESULTS

28 RCTs were included, with 43% of studies adequately reported core characteristics of MHIs according to the TIDieR checklist. Meta-analysis suggested that MHIs may alleviate dyspnoea and improve disease-specific QoL questionnaires (CRQ and CCQ) and generic-related QoL questionnaires (SF-36 and EQ-5D), but not other disease-specific QoL questionnaires (SGRQ and CAT). Subgroup analyses showed that multi-component MHIs were effective in improving dyspnoea. Dyspnoea showed statistically significant improvement at 3 months, 6 months and 12 months, whereas QoL improved at 4 months (SGRQ), 2 months (CAT) and 6 months (CAT).

CONCLUSION

Reporting on the core characteristics of MHIs is currently incomplete, and it is recommended that healthcare professionals develop and report multi-component MHIs based on the TIDieR checklist to help alleviate dyspnoea and enhance QoL in older persons with COPD.

The impacts of a mHealth platform-enabled lifestyle-integrated multicomponent exercise program on reversing pre-frailty in community-dwelling older adults: A randomized controlled trial

BACKGROUND

Multicomponent exercise has robust evidence supporting their effectiveness in preventing pre-frailty/frailty. However, a generalizable model for managing frailty through exercise in real-world settings is still not well defined. A promising approach is to incorporate exercise into daily life. We have developed a lifestyle-integrated multicomponent exercise program supported by a mHealth platform. The objective of this research was to assess its effectiveness and elucidate its potential mechanisms for reversing pre-frailty in community-dwelling older adults.

METHODS

In this prospective, two-arm parallel randomized controlled trial, 134 pre-frail older adult were enrolled from the Fujian Prospective Ageing Cohort. Participants were randomly assigned to either the intervention group (integrating multicomponent exercise into daily life through a mHealth platform) or control group (health education). The primary outcome was the proportion of participants exhibiting pre-frailty after a 6-month intervention. Secondary outcomes included changes in functional fitness, body composition, bone mineral density, physical activity, and sedentary behavior.

RESULT

Of the 134 participants, 52 (77 %) from the intervention group and 54 (81 %) from the control group completed the study. After 6 months, the proportion of pre-frailty was significantly lower in the intervention group compared to the control group (32.8 % vs 98.5 %, P < .001). Improvements were observed in all five frailty components, except for unintentional weight loss. The intervention group also demonstrated significant enhancement in functional fitness, bone mineral density, and body composition (P < .05). Additionally, the intervention group experienced a decrease in sedentary time and an increase in light physical activity, although there was no statistically significant difference in moderate-to-vigorous physical activity.

CONCLUSION

The lifestyle-integrated multicomponent exercise program, facilitated through a mHealth platform, shows promising beneficial effects on reversing pre-frailty, improving functional fitness and body composition, and decreasing sedentary behavior in community-dwelling older adults.

Smartphone application-based pulmonary rehabilitation in COPD: a multicentre randomised controlled trial

BACKGROUND

Pulmonary rehabilitation (PR) is an essential element of chronic obstructive pulmonary disease (COPD) management. However, access to conventional face-to-face PR programmes is limited.

METHODS

This multicentre, randomised controlled trial recruited patients with COPD from 18 sites in Germany and Switzerland, aiming to evaluate the impact of 12 weeks of a mobile app (intervention group; IVG) on quality of life, measured by COPD Assessment Test (CAT), and exercise capacity, assessed by 1-minute-sit-to-stand-test (1MSTST), compared with a control group (CTG) receiving 'enhanced standard-of-care'.

RESULTS

278 patients were included in the study with a median age of 65 years (IQR 60-70) and forced expiratory volume in 1 s 48% predicted (IQR 37-60). In the intention-to-treat analysis at week 12, CAT improved from baseline by median -4 points versus -3 points in the IVG versus CTG groups, respectively (difference: 0 points (95% CI: -1, 2); p=0.7); 1MSTST improved by 1 vs 2 repetitions, respectively (difference: 1 repetition (95% CI: 0, 2); p=0.12)). In a subset of the IVG, with patients grouped by application adherence (≥3 days/week for≥75% of the weeks), adherent users (40.4%) improved 1MSTST versus non-adherent users by median 2 repetitions (95% CI: 1, 3]; p=0.006. Application use did not raise any safety concerns.

CONCLUSIONS

Application-based PR improved outcomes in COPD compared with baseline, and adherent users improved exercise capacity more compared with non-adherent users. Although not statistically significant compared with enhanced standard-of-care, this study may support the use of this application for COPD management and addresses the healthcare challenge of access to PR interventions.

Public mobile chronic obstructive pulmonary disease applications for self-management: Patients and healthcare professionals' perspectives

Poorly controlled chronic obstructive pulmonary disease (COPD) can negatively impact quality of life but mobile applications (apps) are popular digital tools that may mitigate these support needs. However, it is unclear if public mobile COPD apps are acceptable to healthcare professionals and patients, people living with COPD. Objectives: The primary objective is to determine people with COPD and healthcare professionals' perspectives on the appropriateness of public mobile COPD apps for supporting individuals' needs. The secondary objectives were to identify the ideal features and styles of mobile COPD apps for COPD self-management; and to identify the facilitators, barriers and needs for future COPD app research and development. Methods: Public mobile COPD apps were rated by questionnaires administered before and after focus group meetings. Ratings were reported as medians with interquartile ranges and median scores were categorized into three levels of appropriateness: 1-3 for inappropriate; 4-6 for uncertain; and 7-9 for appropriate. Results: A total of 6 people with COPD (mean age 68.2 ± 4.8years) and 22 healthcare professionals (mean age 45 ± 8.3years) completed this study. People with COPD identified one and healthcare professionals identified three public mobile COPD apps to be appropriate. They had different preferences for features and engagement styles but similar preferences for facilitators and barriers to use. Stakeholders mutually rated one public mobile COPD app as appropriate for self-management and emphasized the need for apps to be supplementary and customizable, rather than replacements for clinical management.

Tracking Real-World Physical Activity in Chronic Obstructive Pulmonary Disease Over One Year: Results from a Monocentric, Prospective, Observational Cohort Study

Introduction

Lung function constraints and comorbidities such as coronary heart disease, sarcopenia, and mood disorders make chronic obstructive pulmonary disease (COPD) patients avoid physical activity (PA). However, PA represents an important pillar of COPD management and is explicitly recommended by professional associations to enhance physical functioning and positively modulate disease progression.

Methods

In this monocentric, prospective, observational feasibility study, it was our primary objective to investigate the association between PA and the evolution of the COPD assessment test (CAT) and the occurrence of acute exacerbations of COPD (AECOPD), respectively. To this end, we equipped 42 COPD patients with an activity tracking wearable and telemonitored their daily PA levels over one year using a dedicated web-based interface. Patients additionally provided weekly CAT scores using the same telehealth platform and came in for 3 study visits to assess functional parameters and biochemical markers related to nutrition and inflammation.

Results

A principal study finding was that PA was inversely associated with CAT score (drop of 0.21 points associated with an increase of 1000 daily steps, p = 0.004), and that the 50% of patients with higher PA levels showed less CAT score progression over time (0.42 points per year) than the 50% of patients with lower PA levels (3.26 points per year) (p < 0.001). In addition, higher PA levels were significantly associated with a lower likelihood of experiencing a moderate-to-severe AECOPD (31% risk reduction associated with an increase of 1000 daily steps, p = 0.0097).

Discussion

Our study demonstrates the relevance of PA for key COPD outcome metrics in a real-world setting and underpins the importance of PA for COPD self-management in everyday life. Our study paves the way for future intervention trials to prospectively identify medically relevant PA thresholds and establish training recommendations for different patient subgroups.

Virtual reality for COPD exacerbation: A randomized controlled trial

BACKGROUND

Pulmonary rehabilitation (PR) is an effective treatment method for chronic obstructive pulmonary disease (COPD). However, individuals with chronic diseases that require lifelong treatment and experience exacerbations need motivational methods.

OBJECTIVES

The aim of this study was to examine the effects of virtual reality on symptoms, daily living activity, functional capacity, anxiety and depression levels in COPD exacerbation.

METHODS

Fifty patients hospitalized for COPD exacerbation were included in the study. They were randomly assigned to two groups. Twenty-five patients participated in a traditional PR (once-daily until discharge), including pedaling exercises. The second/25 patients followed the same protocol but experienced cycling simulation in the forest via virtual reality (VR + PR). All patients were evaluated using 1-minute/Sit-to-Stand test (STST), modified-Medical Research Council (mMRC) scale, COPD Assessment test (CAT), Hospital Anxiety and Depression Scale (HADS), and London Chest Activities of Daily Living (LCADL) before and after the treatment.

RESULTS

The STST showed an increase in both groups post-treatment, notably higher in the VR + PR (p = 0.037). Dyspnea levels and CAT scores decreased in all patients, but the decrease was greater in the PR + VR group for both parameters (p = 0.062, p = 0.003; respectively). Both groups experienced a reduction in the HADS scores compared to the pre-treatment, with a more significant decrease in depression and the total score in the VR + PR (p < 0.05). LCADL's sub-parameters and total score, excluding household, decreased in both groups after treatment (p < 0.05). The improvement was more substantial in the VR + PR.

CONCLUSIONS

Virtual reality provides benefits in the management of COPD exacerbations and can be used safely.

Insights into Digital MedicRehApp Maintenance Model for Pulmonary Telerehabilitation: Observational Study

Maintenance strategies after center-based pulmonary rehabilitation (CBPR) are currently needed. This study aimed to evaluate the feasibility and effect on the quality of life of a home-based pulmonary rehabilitation (HBPR) program delivered by a digital app. As secondary objectives, the patients' adherence, symptoms, effort tolerance changes, and safety were evaluated. This was a single-arm prospective observational monocentric study on 30 patients referred for chronic respiratory diseases. The prescription and evaluations of the HBPR programs performed at the pulmonary facility and delivery of structured exercise and counselling by the digital health tool were achieved under the supervision of a respiratory therapist. Digital capabilities included aerobic, strength, and respiratory exercises, which were monitored with a fitness tracker. The engagement rate of the HBPR after the CBPR was 1:10. The EuroQoL VAS score increased from 66.2 ± 16.28 to 75.60 ± 16.07 (p < 0.001), mainly in younger subjects. No patient was lost during the HBPR program. The global adherence session rate was 94%. The Medical Research Council dyspnea scale (MRC), COPD Assessment Test (CAT) score, and six-minute walking test (6MWT) improved from admission into the pulmonary unit to the end of the HBPR program. Between the beginning and end of the CBPR, the CAT score decreased from 14.4 ± 6.39 to 8.50 ± 5.39 (p < 0.001), the MRC decreased from 1.87 ± 0.9 to 1.17 ± 0.83 (p < 0.001), and the 6MWT increased from 451 ± 93 to 473 ± 115 m (p < 0.05). The average Technology Acceptance Model score for usability was high (145 ± 12.1) and no adverse events occurred during the HBPR program. This HBPR model seemed to be feasible and well-accepted by patients, leading to improvements in quality of life, symptoms, and functional capacity.

The Effects of Digital Health Interventions for Pulmonary Rehabilitation in People with COPD: A Systematic Review of Randomized Controlled Trials

Background and Objectives: Chronic Obstructive Pulmonary Disease (COPD) is the third most common cause of death globally. Pulmonary rehabilitation (PR) programmes are important to reduce COPD symptoms and improve the quality of life of people with COPD. Digital health interventions have recently been adopted in PR programmes, which allow people with COPD to participate in such programmes with low barriers. The aim of this study is to review and discuss the reported effects of digital health interventions on PR outcomes in people with COPD. Materials and Methods: To achieve the study goals, a systematic literature search was conducted using PubMed (MEDLINE), CINAHL, AMED, SPORTDiscus and the Physiotherapy Evidence Database. Randomised clinical trials (RCTs) were included if they met specified criteria. Two reviewers independently checked titles, abstracts, and performed full-text screening and data extraction. The quality assessment and risk of bias were performed in accordance with the PEDRO scale and Cochrane Risk of Bias tool 2, respectively. Results: Thirteen RCTs were included in this systematic review with 1525 participants with COPD. This systematic review showed the potential positive effect of digital health PR on the exercise capacity-measured by 6- and 12-min walking tests, pulmonary function, dyspnoea and health-related quality of life. There was no evidence for advantages of digital health PR in the improvement of anxiety, depression, and self-efficacy. Conclusions: Digital health PR is more effective than traditional PR in improving the pulmonary and physical outcomes for people with COPD, but there was no difference between the two PR programmes in improving the psychosocial outcomes. The certainty of the findings of this review is affected by the small number of included studies.

Smartphone applications supporting self-management programme for adults with Chronic Obstructive Pulmonary Disease: A Scoping Review

INTRODUCTION

Chronic Obstructive Pulmonary Disease (COPD) significantly impacts on both the quality and quantity of life for patients due to frequent exacerbations requiring hospital admissions resulting in increased morbidity and mortality. A self-management programme purpose is to increase one's knowledge, confidence, and skills to self-manage their chronic illness such as COPD.

OBJECTIVE

The objective of this review will therefore answer the following research question: What is the current literature pertaining to the use of a smartphone app in supporting a comprehensive self-management programme among COPD patients? A preliminary search was conducted in, Medline, Embase and CINAHL databases to ascertain index terms and keywords. Following this a rigorous search was carried out on Medline, Embase, CINAHL, Web of Science and ASSIA. The findings from this search are presented in tabular form using the PRSIMA flow diagram.

RESULTS

In this review, fifteen studies met the inclusion criteria. Across all studies participants engaged with the app and developed self-management skills and knowledge to manage their chronic illness. However, engagement with the app without third party involvement declined over time. Technical issues did not cause harm to participants but in some cases contributed to reduced engagement. Smartphone self-management apps empowered a cohort of COPD participants to engage in managing their chronic illness which proved useful in detecting exacerbations earlier resulting in reducing the need for hospitalisations over a three-to-six-month period. By reducing hospitalisations incurred a cost savings for health care and an improved quality and quantity of life for these participants.

CONCLUSION

It is evident from the literature that smartphone self-management apps may positively influence participants self-management decisions in terms of knowledge, increase physical activity, self-efficacy that may result in reduced hospitalisation and improved quality of life. It is clear that technical issues and sustained engagement over longer periods of time remains a challenge.

Efficacy of Digital Therapeutics for Pulmonary Rehabilitation: A Multi-Center, Randomized Controlled Trial

BACKGROUND

This study aimed to investigate the efficacy and safety of digital therapeutics (DTx), EASYBREATH, for pulmonary rehabilitation (PR) in patients with chronic respiratory diseases (CRDs).

MATERIALS AND METHODS

This prospective randomized controlled trial was conducted at multiple centers. Participants were randomly allocated 1:1 to the DTx group (DTxG), provided with DTx using EASYBREATH. The DTxG underwent an 8-week PR program with evaluations conducted at baseline, four weeks, and eight weeks. The control group (CG) underwent one PR session and was advised to exercise and undergo the same evaluation. The primary outcome was the change in six-minute walking distance (6MWD) over eight weeks, and secondary outcomes included changes in scores of Modified Medical Research Council (mMRC), chronic obstructive pulmonary disease assessment test (CAT), and St. George's respiratory questionnaire (SGRQ).

RESULTS

The change in 6MWD after eight weeks demonstrated a significant difference between the DTxG and CG (57.68 m vs. 21.71 m, p = 0.0008). The change in mMRC scores (p = 0.0008), CAT scores (p < 0.0001), and total SGRQ scores (p = 0.0003) also showed a significant difference between the groups after eight weeks.

CONCLUSIONS

EASYBREATH significantly improved exercise capacity, alleviated dyspnea, and enhanced the overall quality of life at eight weeks. EASYBREATH is a highly accessible, time-efficient, and effective treatment option for CRD with high compliance.

Clinical Efficacy of Mobile App-Based, Self-Directed Pulmonary Rehabilitation for Patients With Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-Analysis

Background

Pulmonary rehabilitation is well known to improve clinical symptoms (including dyspnea), quality of life, and exercise capacity in patients with chronic obstructive pulmonary disease (COPD). However, researchers have reported difficulties in practicing center-based pulmonary rehabilitation. Recently, mobile app-based pulmonary rehabilitation has become available in clinical practice. We investigated the clinical outcomes of mobile app-based pulmonary rehabilitation in patients with COPD.

Objective

The objective of our study was to evaluate the clinical efficacy of mobile app-based pulmonary rehabilitation versus conventional center-based pulmonary rehabilitation for patients with COPD, using a systematic review and meta-analysis.

Methods

A systematic search of the literature published between January 2007 and June 2023 was performed, using the PubMed, Embase, Cochrane, and CINAHL databases to identify relevant randomized controlled trials involving patients with COPD. Pulmonary rehabilitation programs needed to provide an exercise program on a smartphone app. Study outcomes, including exercise capacity, symptom scores, quality of life, and hospitalization, were evaluated. The meta-analysis evaluated mean differences in 6-minute walk test distances (6MWDs), COPD Assessment Test (CAT) scores, modified Medical Research Council (mMRC) dyspnea scale scores, St. George Respiratory Questionnaire (SGRQ) scores, and risk ratios for hospitalization resulting from disease exacerbation.

Results

Of the 1173 screened studies, 10 were included in the systematic review and 9 were included in the meta-analysis. Further, 6 studies were multicenter studies. There were a total of 1050 participants, and most were aged ≥65 years. There were discrepancies in the baseline participant characteristics, smartphone apps, interventions, and study outcomes among the included studies. In the meta-analysis, 5 studies assessed 6MWDs (mean difference 9.52, 95% CI -3.05 to 22.08 m), 6 studies assessed CAT scores (mean difference -1.29, 95% CI -2.39 to -0.20), 3 studies assessed mMRC dyspnea scale scores (mean difference -0.08, 95% CI -0.29 to 0.13), 2 studies assessed SGRQ scores (mean difference -3.62, 95% CI -9.62 to 2.38), and 3 studies assessed hospitalization resulting from disease exacerbation (risk ratio 0.65, 95% CI 0.27-1.53). These clinical parameters generally favored mobile app-based pulmonary rehabilitation; however, a statistically significant difference was noted only for the CAT scores (P=.02).

Conclusions

Despite some discrepancies in the baseline participant characteristics and interventions among studies, mobile app-based pulmonary rehabilitation resulted in favorable exercise capacity, symptom score, quality of life, and hospitalization outcomes when compared with conventional pulmonary rehabilitation. In the meta-analysis, the CAT scores of the mobile app-based pulmonary rehabilitation group were significantly lower than those of the control group (P=.02). In real-world practice, mobile app-based pulmonary rehabilitation can be a useful treatment option when conventional center-based pulmonary rehabilitation is not feasible.

Effectiveness of smartphone application in increasing knowledge on COPD and its non-pharmacological management in COPD patients

Chronic obstructive pulmonary disease (COPD) is among top ten of the world's causes of death. The development of the "Paru Sehat" smartphone application is a positive initiative and might have the potential to improve the disease management of COPD, improve patient's quality of life, and reduce complications associated with COPD. However, its effectiveness in improving the knowledge of the COPD patients is unknown. The aim of this study was to determine the effectiveness of "Paru Sehat" in increasing knowledge on COPD and its non-pharmacological management in COPD patients. A quasi-experimental study with a one-group pretest-posttest was conducted among stable COPD patients at Prof. Chairuddin Panusunan Lubis Hospital, Medan, Indonesia. Bristol COPD knowledge questionnaire (BCKQ) was used to assess the knowledge scores of the patients before and after exposure to the "Paru Sehat" twice a week for four weeks. A dependent Student t-test was used to compare the knowledge scores between pre- and post-intervention for both knowledge domains (i.e., knowledge on the disease and non-pharmacological management). Student t-test or one-way ANOVA were used to determine the association between patients' characteristics and the knowledge scores within pre- and posttreatment. Our data indicated a significant improvement of the knowledge scores on disease between pre- and post-treatment (15.92±3.79 vs 19.56±3.68, p<0.001). The knowledge score on non-pharmacological management also increased significantly post-treatment (7.52±2.02) compared to pre-treatment (10.08±2.379), p<0.001. In addition, this study found that educational attainment was associated with the scores of both knowledge domains of which individuals with senior high school or higher education level had significantly improvement of knowledge scores. This study highlights that although "Paru Sehat" application could improve the knowledge on COPD and its non-pharmacological management, its effects are less effective among individuals with low educational attainment.

Wearable technology interventions in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and is associated with multiple medical and psychological comorbidities. Therefore, future strategies to improve COPD management and outcomes are needed for the betterment of patient care. Wearable technology interventions offer considerable promise in improving outcomes, but prior reviews fall short of assessing their role in the COPD population. In this systematic review and meta-analysis we searched ovid-MEDLINE, ovid-EMBASE, CINAHL, CENTRAL, and IEEE databases from inception to April 2023 to identify studies investigating wearable technology interventions in an adult COPD population with prespecified outcomes of interest including physical activity promotion, increasing exercise capacity, exacerbation detection, and quality-of-life. We identified 7396 studies, of which 37 were included in our review. Meta-analysis showed wearable technology interventions significantly increased: the mean daily step count (mean difference (MD) 850 (494-1205) steps/day) and the six-minute walk distance (MD 5.81 m (1.02-10.61 m). However, the impact was short-lived. Furthermore, wearable technology coupled with another facet (such as health coaching or pulmonary rehabilitation) had a greater impact that wearable technology alone. Wearable technology had little impact on quality-of-life measures and had mixed results for exacerbation avoidance and prediction. It is clear that wearable technology interventions may have the potential to form a core part of future COPD management plans, but further work is required to translate this into meaningful clinical benefit.

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.

Sustaining training effects through physical activity coaching (STEP): a randomized controlled trial

BACKGROUND

Pulmonary rehabilitation (PR) programs improve physical fitness, symptoms and quality of life (QoL) of patients with COPD. However, improved physical activity (PA) is not guaranteed after PR and the clinical benefits fade off after PR discharge. We aimed to investigate whether a 9 months PA-telecoaching program is able to improve PA of patients with COPD, after 3 months of PR and if this leads to maintenance of PR-acquired benefits.

METHODS

Patients with COPD enrolled in a 6-month PR program were randomized to a (semi-automated) PA-telecoaching program or usual care, 3 months after PR initiation. The intervention consisted of a smartphone application with individual targets and feedback (for 6 months) and self-monitoring with a step counter (for 9 months). Patients were followed up for 9 months after randomization. Primary outcome was PA (daily step count by accelerometery), secondary outcomes were exercise tolerance, quadriceps force, dyspnea and QoL.

RESULTS

Seventy-three patients were included (mean ± SD: 65 ± 7 years, FEV1 49 ± 19%, 6MWD 506 ± 75 m, PA 5225 ± 2646 steps/day). The intervention group presented a significant improvement in steps/day at every visit compared to usual care (between-group differences mean ± SE: 1431 ± 555 steps/day at 9 months after randomization, p = 0.01). Secondary outcomes did not differ between the groups.

CONCLUSION

The semi-automated PA-telecoaching program implemented after 3 months of PR was effective to improve the amount of PA (steps/day) during PR and after follow-up. However, this was not accompanied by the maintenance of other PR-acquired benefits.

Stakeholder Perceptions of a Web-Based Physical Activity Intervention for COPD: A Mixed-Methods Study

Technology-based physical activity interventions have been shown to be efficacious in chronic obstructive pulmonary disease (COPD), though their potential impact has not been fully realized due to ineffective implementation. We used a convergent, parallel mixed-methods design to identify patient- and provider-facing barriers and facilitators to implementing a rigorously studied web-based physical activity intervention for COPD. Quantitative surveys (based on the unified theory of acceptance and use of technology; range 1 (poor usability)-5 (high usability)) and semi-structured interviews (guided by the practical robust implementation and sustainability model) assessed the perspectives of 15 patients and 15 health care providers. The patients and providers rated the usability of the intervention as high (median = 5.0, IQR = 1.0). For both patients and providers, the main facilitators included: the potential high impact of the intervention on patient health, the usefulness of the intervention for unmet clinical needs, and the perceived ease of use of the intervention. The main barriers identified were digital literacy and its fit with current clinical workflows. Implementation efforts may benefit from supporting patients' use of the website and developing strategies to integrate referrals to the intervention and the monitoring of patients into current clinical infrastructures.

Benefits from Incorporating Virtual Reality in Pulmonary Rehabilitation of COPD Patients: A Systematic Review and Meta-Analysis

Chronic Obstructive Pulmonary Disease (COPD) is characterized by irreversible airflow limitation. Patient participation in Pulmonary Rehabilitation (PR) programs has a beneficial effect on disease management, improving patients' functional capacity and quality of life. As an alternative to traditional programs or as a complementary activity, the inclusion of virtual reality (VR) games is proposed. The aim of this research study was to investigate the effectiveness of incorporating VR in the pulmonary rehabilitation program of patients with COPD. A systematic literature search was performed for randomized controlled trials (RCTs) in the electronic databases Google Scholar, PubMed, and Pedro from January 2014 to March 2022. The search involved screening for studies examining the effectiveness of enhancing PR with VR. The PEDro (Physiotherapy Evidence Database) scale was chosen as the tool to assess the quality of studies. A meta-analysis was performed where possible. Six studies were included in this systematic review. The PEDro scale showed five studies of good methodological quality and one of fair quality. The variables examined were: aerobic capacity for exercise, lung function, anxiety and depression, with non-significant improvement for the MRC Dyspnea scale, marginally non-significant improvement regarding 6MWT (p = 0.05) and significant improvement for FEV1 (p < 0.05). There was variability noted in the VR applications and the proposed rehabilitation that the experimental groups followed. The application of VR is recommended for COPD patients, in combination with conventional PR. VR was found to be effective in increasing therapeutic effect and should be considered as a mean of increasing accessibility to PR. Therefore, further research, as well as additional RCTs regarding the effectiveness of VR in patients with COPD, seems necessary.

[Pulmonary Rehabilitation]

Reduced exercise capacity, skeletal muscle dysfunction, and a physically inactive lifestyle are linked with symptoms of fatigue and dyspnea in people suffering from chronic lung disease. Numerous such extrapulmonary manifestations have been identified as treatable aspects of pulmonary rehabilitation (PR). PR is an extensive personalized non-pharmaceutical intervention, encompassing, but not limited to, exercise training, respiratory therapy, and education. The content and goals of a PR-program are based on a comprehensive patient assessment at the time of rehabilitation admission, with personalized therapies provided by a multidisciplinary team of healthcare professionals. This article provides an overview of PR including possible indications, therapy contents (e. g. exercise training, respiratory therapy), and evidence (COPD, interstitial lung disease, COVID-19). Finally, options for pulmonary rehabilitation maintenance services in Germany are presented.

Pulmonary rehabilitation after severe exacerbation of COPD: a nationwide population study

BACKGROUND

Acute exacerbations of chronic obstructive pulmonary disease (COPD) lead to a significant reduction in quality of life and an increased mortality risk. Current guidelines strongly recommend pulmonary rehabilitation (PR) after a severe exacerbation. Studies reporting referral for PR are scarce, with no report to date in Europe. Therefore, we assessed the proportion of French patients receiving PR after hospitalization for COPD exacerbation and factors associated with referral.

METHODS

This was a national retrospective study based on the French health insurance database. Patients hospitalized in 2017 with COPD exacerbation were identified from the exhaustive French medico-administrative database of hospitalizations. In France, referral to PR has required as a stay in a specialized PR center or unit accredited to provide multidisciplinary care (exercise training, education, etc.) and admission within 90 days after discharge was assessed. Multivariate logistic regression was used to assess the association between patients' characteristics, comorbidities according to the Charlson index, treatment, and PR uptake.

RESULTS

Among 48,638 patients aged ≥ 40 years admitted for a COPD exacerbation, 4,182 (8.6%) received PR within 90 days after discharge. General practitioner's (GP) density (number of GPs for the population at regional level) and PR center facilities (number of beds for the population at regional level) were significantly correlated with PR uptake (respectively r = 0.64 and r = 0.71). In multivariate analysis, variables independently associated with PR uptake were female gender (aOR 1.36 [1.28-1.45], p < 0.0001), age (p < 0.0001), comorbidities (p = 0.0013), use of non-invasive ventilation and/or oxygen therapy (aOR 1.52 [1.41-1.64], p < 0.0001) and administration of long-acting bronchodilators (p = 0.0038).

CONCLUSION

This study using the French nationally exhaustive health insurance database shows that PR uptake after a severe COPD exacerbation is dramatically low and must become a high-priority management strategy.

Comparing the effects of smartphone-based and face-to-face pulmonary rehabilitation education on caregiver burden and quality of life among the family caregivers of patients with chronic obstructive pulmonary disease: a randomized controlled field trial

BACKGROUND

Functional limitation among patients with chronic obstructive pulmonary disorder (COPD) and their dependence on their family caregivers (FCs) can significantly increase caregiver burden (CB) and reduce the quality of life (QOL) among FCs. Education of pulmonary rehabilitation (PR) to FCs is a strategy with potential positive effects on CB. This study was conducted to compare the effects of smartphone-based and face-to-face (FTF) PR education on CB and QOL among the FCs of patients with COPD.

METHODS

This randomized controlled field trial was conducted in 2021-2022. Participants were purposefully selected from the PR unit of Khorshid comprehensive respiratory care clinic in Isfahan, Iran, and randomly allocated to a control and an intervention group. Participants in the control group received PR education in twelve 30-60-min FTF sessions held twice weekly in six consecutive weeks. Their counterparts in the intervention group received PR education for 6 weeks through an android application. The Zarit Burden Interview and the 12-item Short Form Health Survey (SF-12) were used for data collection before and immediately after the study intervention. The SPSS software (v. 24.0) was used to analyze the data through the independent-sample t, paired-sample t, chi-square, and Fisher's exact tests.

RESULTS

The means of participants' age was 47.7 ± 13.8 years in the control group and 44.1 ± 14.8 years in the intervention group. Most participants in these groups were female (82.9% vs. 71.4%). The pretest mean scores of CB and QOL were respectively 50.77 ± 10.64 and 27.82 ± 3.9 in the control group and 49.77 ± 7.65 and 26.71 ± 3.5 in the intervention group with no significant between-group difference (P > 0.05). At the posttest, these values were respectively 51.57 ± 7.32 and 27.74 ± 3.28 in the control group and 37.31 ± 6.95 and 34.37 ± 2.8 in the intervention group, and between-group differences were significant (P < 0.05). The mean scores of CB and QOL did not significantly change in the control group (P > 0.05), but respectively decreased and increased significantly in the intervention group (P < 0.05).

CONCLUSIONS

Smartphone-based PR education is effective in significantly decreasing CB and improving QOL among the FCs of patients with COPD.

Telemedicine in the management of chronic obstructive pulmonary disease: A systematic review

Telemedicine is defined as the use of electronic technology for information and communication by healthcare professionals with patients (or care givers) aiming at providing and supporting healthcare to patients away from healthcare institutions. This systematic review over the last decade (2013-2022) investigates the use of telemedicine in patients with chronic obstructive pulmonary disease (COPD). We identified 53 publications related to: (1) home tele-monitorization; (2) tele-education and self-management; (3) telerehabilitation; and (4) mobile health (mHealth). Results showed that, although evidence is still weak in many of these domains, results are positive in terms of improvement of health-status, use of health-care resources, feasibility, and patient satisfaction. Importantly, no safety issues were identified. Thus, telemedicine can be considered today as a potential complement to usual healthcare.

Physical activity promotion interventions in chronic airways disease: a systematic review and meta-analysis

Physical inactivity is common in people with chronic airways disease (pwCAD) and associated with worse clinical outcomes and impaired quality of life. We conducted a systematic review and meta-analysis to characterise and evaluate the effectiveness of interventions promoting step-based physical activity (PA) in pwCAD. We searched for studies that included a form of PA promotion and step-count outcome measure. A random-effects model was used to determine the overall effect size using post-intervention values. 38 studies (n=32 COPD; n=5 asthma; n=1 bronchiectasis; study population: n=3777) were included. Overall, implementing a form of PA promotion resulted in a significant increase in step-count: median (IQR) 705 (183-1210) when compared with usual standard care: -64 (-597-229), standardised mean difference (SMD) 0.24 (95% CI: 0.12-0.36), p<0.01. To explore the impact of specific interventions, studies were stratified into subgroups: PA promotion+wearable activity monitor-based interventions (n=17) (SMD 0.37, p<0.01); PA promotion+step-count as an outcome measure (n=9) (SMD 0.18, p=0.09); technology-based interventions (n=12) (SMD 0.16, p=0.01). Interventions promoting PA, particularly those that incorporate wearable activity monitors, result in a significant and clinically meaningful improvement in daily step-count in pwCAD.
