Video Telehealth Pulmonary Rehabilitation Intervention in Chronic Obstructive Pulmonary Disease Reduces 30-Day Readmissions

The effect of telemedicine employing telemonitoring instruments on readmissions of patients with heart failure and/or COPD: a systematic review

Background

Hospital readmissions pose a challenge for modern healthcare systems. Our aim was to assess the efficacy of telemedicine incorporating telemonitoring of patients' vital signs in decreasing readmissions with a focus on a specific patient population particularly prone to rehospitalization: patients with heart failure (HF) and/or chronic obstructive pulmonary disease (COPD) through a comparative effectiveness systematic review.

Methods

Three major electronic databases, including PubMed, Scopus, and ProQuest's ABI/INFORM, were searched for English-language articles published between 2012 and 2023. The studies included in the review employed telemedicine incorporating telemonitoring technologies and quantified the effect on hospital readmissions in the HF and/or COPD populations.

Results

Thirty scientific articles referencing twenty-nine clinical studies were identified (total of 4,326 patients) and were assessed for risk of bias using the RoB2 (nine moderate risk, six serious risk) and ROBINS-I tools (two moderate risk, two serious risk), and the Newcastle-Ottawa Scale (three good-quality, four fair-quality, two poor-quality). Regarding the primary outcome of our study which was readmissions: the readmission-related outcome most studied was all-cause readmissions followed by HF and acute exacerbation of COPD readmissions. Fourteen studies suggested that telemedicine using telemonitoring decreases the readmission-related burden, while most of the remaining studies suggested that it had a neutral effect on hospital readmissions. Examination of prospective studies focusing on all-cause readmission resulted in the observation of a clearer association in the reduction of all-cause readmissions in patients with COPD compared to patients with HF (100% vs. 8%).

Conclusions

This systematic review suggests that current telemedicine interventions employing telemonitoring instruments can decrease the readmission rates of patients with COPD, but most likely do not impact the readmission-related burden of the HF population. Implementation of novel telemonitoring technologies and conduct of more high-quality studies as well as studies of populations with ≥2 chronic disease are necessary to draw definitive conclusions.

Predictive value of diaphragm ultrasound for mechanical ventilation outcome in patients with acute exacerbation of chronic obstructive pulmonary disease

BACKGROUND

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is often combined with respiratory failure, which increases the patient's morbidity and mortality. Diaphragm ultrasound (DUS) has developed rapidly in the field of critical care in recent years. Studies with DUS monitoring diaphragm-related rapid shallow breathing index have demonstrated important results in guiding intensive care unit patients out of the ventilator. Early prediction of the indications for withdrawal of non-invasive ventilator and early evaluation of patients to avoid or reduce disease progression are very important.

AIM

To explore the predictive value of DUS indexes for non-invasive ventilation outcome in patients with AECOPD.

METHODS

Ninety-four patients with AECOPD who received mechanical ventilation in our hospital from January 2022 to December 2023 were retrospectively analyzed, and they were divided into a successful ventilation group (68 cases) and a failed ventilation group (26 cases) according to the outcome of ventilation. The clinical data of patients with successful and failed noninvasive ventilation were compared, and the independent predictors of noninvasive ventilation outcomes in AECOPD patients were identified by multivariate logistic regression analysis.

RESULTS

There were no significant differences in gender, age, body mass index, complications, systolic pressure, heart rate, mean arterial pressure, respiratory rate, oxygen saturation, partial pressure of oxygen, oxygenation index, or time of inspiration between patients with successful and failed mechanical ventilation (P > 0.05). The patients with successful noninvasive ventilation had shorter hospital stays and lower partial pressure of carbon dioxide (PaCO2) than those with failed treatment, while potential of hydrogen (pH), diaphragm thickening fraction (DTF), diaphragm activity, and diaphragm movement time were significantly higher than those with failed treatment (P < 0.05). pH [odds ratio (OR) = 0.005, P < 0.05], PaCO2 (OR = 0.430, P < 0.05), and DTF (OR = 0.570, P < 0.05) were identified to be independent factors influencing the outcome of mechanical ventilation in AECOPD patients.

CONCLUSION

The DUS index DTF can better predict the outcome of non-invasive ventilation in AECOPD patients.

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.

Effect of telemonitoring and telerehabilitation on physical activity, exercise capacity, health-related quality of life and healthcare use in patients with chronic lung diseases or COVID-19: A scoping review

BACKGROUND

Telemonitoring and telerehabilitation can support home-based pulmonary rehabilitation (PR) and benefit patients with lung diseases or COVID-19. This study aimed to (1) identify which telemonitoring and telerehabilitation interventions (e.g. videoconferencing) are used to provide telehealth care for people with chronic respiratory conditions or COVID-19, and (2) provide an overview of the effects of telemonitoring and telerehabilitation on exercise capacity, physical activity, health-related QoL (HRQoL), and healthcare use in patients with lung diseases or COVID-19.

METHODS

A search was performed in the electronic databases of Ovid MEDLINE, EMBASE, and Cinahl through 15 June 2021. Subject heading and keywords were used to reflect the concepts of telemonitoring, telerehabilitation, chronic lung diseases, and COVID-19. Studies that explored the effect of a telerehabilitation and/or telemonitoring intervention, in patients with a chronic lung disease such as asthma, chronic obstructive pulmonary diseases (COPD), or COVID-19, and reported the effect of the intervention in one or more of our outcomes of interest were included. Excluding criteria included evaluation of new technological components, teleconsultation or one-time patient assessment.

RESULTS

This scoping review included 44 publications reporting the effect of telemonitoring (25 studies), telerehabilitation (8 studies) or both (11 studies) on patients with COPD (35 studies), asthma (5 studies), COPD and asthma (1 study), and COVID-19 (2 studies). Patients who received telemonitoring and/or telerehabilitation had improvements in exercise capacity in 9 out of 11 (82%) articles, better HRQoL in 21 out of 25 (84%), and fewer health care use in 3 out of 3 (100%) articles compared to pre-intervention. Compared to controls, no statistically significant differences were found in the intervention groups' exercise capacity in 5 out 6 (83%) articles, physical activity in 3 out of 3 (100%) articles, HRQoL in 21 out of 25 (84%) articles, and healthcare use in 15 out of 20 (75%) articles. The main limitation of the study was the high variability between the characteristics of the studies, such as the number and age of the patients, the outcome measures, the duration of the intervention, the technological components involved, and the additional elements included in the interventions that may influence the generalization of the results.

CONCLUSION

Telemonitoring and telerehabilitation interventions had a positive effect on patient outcomes and appeared to be as effective as standard care. Therefore, they are promising alternatives to support remote home-based rehabilitation in patients with chronic lung diseases or COVID-19.

Determining If COPD Self-Management Televisit-Based Interventions Are Evaluated Among and Equitably Effective Across Diverse Patient Populations to Reduce Acute Care Use: A Scoping Review

TOPIC IMPORTANCE

With telemedicine's expansion during the COVID-19 pandemic, it has become critical to evaluate whether patients have equitable access and capabilities to use televisits optimally for improved COPD outcomes such as reduced hospitalizations. This scoping review evaluated whether televisit-based interventions are evaluated and equitably effective in improving health care use outcomes among diverse patient populations with COPD.

REVIEW FINDINGS

Using a systematic search for televisit-based COPD self-management interventions, we found 20 studies for inclusion, all but one of which were published before the COVID-19 pandemic. Most (11/20) were considered good-quality studies. Most studies (19/20) reported age and sex; few provided race (3/20) or income (1/20) data. The most frequently used televisit-based methods were in person plus phone (6/20), video only (6/20), and phone only (4/20). Most studies (12/20) showed a significant reduction in at least one health care use metric; nine studies found hospitalization-related reductions. Effective interventions typically used two methods (eg, in person plus televisits), a video methods, or both.

SUMMARY

Most studies failed to report on participants' race or income, leading to a lack of data on the equity of interventions' effectiveness across diverse patient populations. Multimethod televisit-based interventions, particularly with an in-person component, most commonly were effective; no associations were seen with study quality or size. With the increasing reliance on telemedicine to provide chronic disease care, the lack of data among diverse populations since the COVID-19 pandemic began limits generalizability of these findings for real-world clinical settings. More comprehensive evaluations of televisit-based interventions are needed in the era after the pandemic within and across diverse patient populations.

Psychosocial Support in Pulmonary Rehabilitation

Pulmonary rehabilitation (PR) improves exercise capacity and quality of life (QOL) while reducing dyspnea in patients with COPD. However, little is known about the efficacy of PR, cognitive behavioral therapy (CBT), or antidepressant drug therapy on psychosocial factors in patients with COPD. Knowledge gaps include which therapy is most efficacious, what barriers exist for each treatment, and the optimal duration of each intervention. Potential barriers to antidepressant therapy include patient fears of potential adverse effects, apprehension and misconception, and stigma related to depression. Both CBT and PR reduce anxiety and depressive symptoms in short-term studies. However, their potential benefits over medium-to-long-term follow-up and specifically on psychosocial factors warrant exploration. Furthermore, new emerging treatment strategies such as the collaborative care model and home-based telehealth coaching are promising interventions to promote patient-centered care treatment and reduce psychosocial factors adversely affecting patients with COPD. This update and critical synthesis reviews the effectiveness of both pharmacologic and non-pharmacologic interventions on psychosocial factors in patients with COPD. It also provides brief screening tools used in the assessment of anxiety and depression for patients with COPD.

Maintenance Pulmonary Rehabilitation: An Update and Future Directions

The Global Initiative for Chronic Obstructive Lung Disease guidelines recommend pulmonary rehabilitation (PR) for individuals with COPD to improve exercise capacity and health-related quality of life (HRQOL) and reduce symptoms of dyspnea. For cost-effectiveness in COPD care, PR is second only to smoking cessation. However, PR programs typically last 9-12 weeks. The benefits of PR in terms of exercise capacity and HRQOL often decrease toward pre-PR levels as early as 3-6 months after completing PR if patients do not continue to engage in exercise. This review will (1) briefly summarize the efficacy data that informed the 2023 American Thoracic Society (ATS) clinical practice guidelines for maintenance PR, (2) discuss exercise components of maintenance PR studied since 2020 when the last papers were included in the ATS guidelines, (3) explore future directions for delivery of maintenance PR using technology-mediated models, and (4) examine the need for behavior change techniques informed by theoretical models that underpin long-term behavior change. This review will focus on persons with COPD who have completed an out-patient core initial PR program as most of the data on maintenance PR have been published in this patient population. Core PR typically implies a facility-based initial intensive structured program. All patients who complete a core initial PR program should be counseled by PR staff at the discharge visit to engage in ongoing exercise. This usual care is equally as important as referral to a formal PR maintenance program. It is critical to emphasize that usual care after core initial PR means all patients should be supported to participate in regular ongoing exercise, regardless of whether supervised maintenance PR is available. Currently, the optimal frequency, exercise and/or physical activity content, and delivery mode for maintenance PR in persons with COPD and other chronic respiratory diseases remain unknown. Patient safety and degree of in-person supervision required due to the severity of the underlying lung disease need to be considered. Future research of maintenance PR should be underpinned by behavior change techniques. Finally, in the setting of finite resources, balancing the competing priorities of core initial programs with those of maintenance PR programs needs to be achieved.

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.

Internet of things-based management versus standard management of home noninvasive ventilation in COPD patients with hypercapnic chronic respiratory failure: a multicentre randomized controlled non-inferiority trial

Background

Effective monitoring and management are crucial during long-term home noninvasive positive pressure ventilation (NPPV) in patients with hypercapnic chronic obstructive pulmonary disease (COPD). This study investigated the benefit of Internet of Things (IOT)-based management of home NPPV.

Methods

This multicenter, prospective, parallel-group, randomized controlled non-inferiority trial enrolled patients requiring long-term home NPPV for hypercapnic COPD. Patients were randomly assigned (1:1), via a computer-generated randomization sequence, to standard home management or IOT management based on telemonitoring of clinical and ventilator parameters over 12 months. The intervention was unblinded, but outcome assessment was blinded to management assignment. The primary outcome was the between-group comparison of the change in health-related quality of life, based on severe respiratory insufficiency questionnaire scores with a non-inferiority margin of -5. This study is registered with Chinese Clinical Trials Registry (No. ChiCTR1800019536).

Findings

Overall, 148 patients (age: 72.7 ± 6.8 years; male: 85.8%; forced expiratory volume in 1 s: 0.7 ± 0.3 L; PaCO2: 66.4 ± 12.0 mmHg), recruited from 11 Chinese hospitals between January 24, 2019, and June 28, 2021, were randomly allocated to the intervention group (n = 73) or the control group (n = 75). At 12 months, the mean severe respiratory insufficiency questionnaire score was 56.5 in the intervention group and 50.0 in the control group (adjusted between-group difference: 6.26 [95% CI, 3.71-8.80]; P < 0.001), satisfying the hypothesis of non-inferiority. The 12-month risk of readmission was 34.3% in intervention group compared with 56.0% in the control group, adjusted hazard ratio of 0.56 (95% CI, 0.34-0.92; P = 0.023). No severe adverse events were reported.

Interpretation

Among stable patients with hypercapnic COPD, using IOT-based management for home NPPV improved health-related quality of life and prolonged the time to readmission.

Feasibility and Design Factors for Home-Based Pulmonary Rehabilitation of Patients With Chronic Obstructive Pulmonary Disease and Chronic Lung Diseases Based on a People-Object-Environment Framework: Qualitative Interview Study

BACKGROUND

The feasibility of implementing home-based pulmonary rehabilitation (PR) can be assessed from the perspectives of patients with chronic lung disease and health care professionals involved in PR.

OBJECTIVE

Through a qualitative inquiry using interviews and the adoption of the people-object-environment framework, this study aims to understand the influences of interpersonal, environmental, and situational factors on the perceptions and considerations of individuals involved in home-based PR for patients with chronic lung disease.

METHODS

One-on-one interviews were conducted with 20 patients with chronic lung disease and 20 health care professionals for investigating their attitudes and opinions based on their experiences regarding home-based PR as well as for identifying the key factors affecting the benefits and drawbacks of such therapies. This study further evaluates the feasibility of using digital tools for medical diagnosis and treatment by examining the technology usage of both parties.

RESULTS

The 4 key issues that all participants were the most concerned about were as follows: distance to outpatient medical care, medical efficiency, internet connectivity and equipment, and physical space for diagnosis and treatment. Interviews with patients and health care professionals revealed that the use of technology and internet was perceived differently depending on age and area of residence. Most participants reported that digital tools and internet connectivity had many benefits but still could not solve all the problems; moreover, these same digital tools and network transmission could lead to problems such as information security and digital divide concerns. This study also emphasizes the significant impact of human behavior and thinking on shaping the design of health care interventions and technologies. Understanding user perspectives and experiences is crucial for developing effective solutions for unmet needs.

CONCLUSIONS

The results of this study indicate that despite the different perspectives of patients and health care professionals, their considerations of the key issues are very similar. Therefore, the implementation of plans related to telemedicine diagnosis, treatment, or rehabilitation should take the suggestions and considerations of both parties into account as crucial factors for telehealth care design.

Content, Mechanism, and Outcome of Effective Telehealth Solutions for Management of Chronic Obstructive Pulmonary Diseases: A Narrative Review

Telehealth (TH) solutions for Chronic Obstructive Pulmonary Disease (COPD) are promising behavioral therapeutic interventions and can help individuals living with COPD to improve their health status. The linking content, mechanism, and outcome of TH interventions reported in the literature related to COPD care are unknown. This paper aims to summarize the existing literature about structured TH solutions in COPD care. We conducted an electronic search of the literature related to TH solutions for COPD management up to October 2023. Thirty papers presented TH solutions as an innovative treatment to manage COPD. TH and digital health solutions are used interchangeably in the literature, but both have the potential to improve care, accessibility, and quality of life. To date, current TH solutions in COPD care have a variety of content, mechanisms, and outcomes. TH solutions can enhance education as well as provide remote monitoring. The content of TH solutions can be summarized as symptom management, prompt physical activity, and psychological support. The mechanism of TH solutions is manipulated by factors such as content, mode of delivery, strategy, and intensity. The most common outcome measures with TH solutions were adherence to treatment, health status, and quality of life. Implementing effective TH with a COPD care bundle must consider important determinants such as patient's needs, familiarity with the technology, healthcare professional support, and data privacy. The development of effective TH solutions for COPD management also must consider patient engagement as a positive approach to optimizing implementation and effectiveness.

Postdischarge Video Visits for Adherence to Hospital Discharge Recommendations: A Randomized Clinical Trial

Objective

To determine whether a postdischarge video visit with patients, conducted by hospital medicine advanced practice providers, improves adherence to hospital discharge recommendations.

Patients and Methods

We conducted a single-institution 2-site randomized clinical trial with 1:1 assignment to intervention vs control, with enrollment from August 10, 2020, to June 23, 2022. Hospital medicine patients discharged home or to an assisted living facility were randomized to a video visit 2-5 days postdischarge in addition to usual care (intervention) vs usual care (control). During the video visit, advanced practice providers reviewed discharge recommendations. Both intervention and control groups received telephone follow-up 3-6 days postdischarge to ascertain the primary outcome of adherence to all discharge recommendations for new and chronic medication management, self-management and action plan, and home support.

Results

Among 1190 participants (594 intervention; 596 control), the primary outcome was ascertained in 768 participants (314 intervention; 454 control). In intervention vs control, there was no difference in the proportion of participants with the primary outcome (76.7% vs 72.5%; P=.19) or in the individual domains of the primary outcome: new and chronic medication management (94.1% vs 92.8%; P=.50), self-management and action plan (76.5% vs 71.5%; P=.18), and home support (94.1% vs 94.3%; P=.94). Women receiving intervention vs control had higher adherence to recommendations (odds ratio, 1.77; 95% CI, 1.08-2.91).

Conclusion

In hospital medicine patients, a postdischarge video visit did not improve adherence to discharge recommendations. Potential gender differences in adherence require further investigation.Clinicaltrials.gov number, NCT04547803.

Digital health in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) can be prevented and treated through effective care, reducing exacerbations and hospitalizations. Early identification of individuals at high risk of COPD exacerbation is an opportunity for preventive measures. However, many patients struggle to follow their treatment plans because of a lack of knowledge about the disease, limited access to resources, and insufficient clinical support. The growth of digital health-which encompasses advancements in health information technology, artificial intelligence, telehealth, the Internet of Things, mobile health, wearable technology, and digital therapeutics-offers opportunities for improving the early diagnosis and management of COPD. This study reviewed the field of digital health in terms of COPD. The findings showed that despite significant advances in digital health, there are still obstacles impeding its effectiveness. Finally, we highlighted some of the major challenges and possibilities for developing and integrating digital health in COPD management.

Access to Pulmonary Rehabilitation among Medicare Beneficiaries with Chronic Obstructive Pulmonary Disease

Rationale: Pulmonary rehabilitation (PR) remains substantially underused as a treatment modality for chronic obstructive pulmonary disease (COPD). A major barrier to the uptake of PR is the poor availability of and access to PR. Objectives: To quantify patients' access to PR centers in the United States. Methods: Using the 100% Medicare population with coverage for 2018, four geodesic distance-based buffers of 10-, 15-, 25-, and 50-mi radii around the geographic centroid of each ZIP code with at least one beneficiary with COPD were created. Street addresses of PR centers across the continental United States were geocoded. We calculated the distance between the residential ZIP code centroid and the closest PR center. The proportions of individuals with at least one PR center available within the four distance buffers were calculated overall as well as in metropolitan, micropolitan, small-town, and rural areas. Results: Of 62,930,784 Medicare beneficiaries, 10,376,949 (16.5%) had COPD. There were 1,696 PR centers across the United States, with one PR center for every 6,030 individuals with COPD. Mean distance to the nearest PR center was 12.4 (standard deviation, 16.6) mi. Overall, the proportions of individuals with COPD who had PR centers available within 10-, 15-, 25-, and 50-mi radii were 61.5%, 73.2%, 86.6%, and 97.1%, respectively. Proportions for rural areas were 11.3%, 24.3%, 53.4%, and 88.6%, respectively. Compared with those living in metropolitan areas, those living in rural areas were 95% less likely to have PR centers within 10 mi of their residences (odds ratio, 0.048 [95% confidence interval, 0.039-0.057]). Conclusions: In a nationally representative sample of Medicare beneficiaries, we found that two-fifths of adults with COPD overall, and eight in nine of those in rural areas, have poor access to PR.

Effects of post-discharge telemonitoring on 30-day chronic obstructive pulmonary disease readmissions and mortality

INTRODUCTION

Much attention has been focused on decreasing chronic obstructive pulmonary disease (COPD) hospital readmissions. The US health system has struggled to meet this goal. The objective of this study was to assess the efficacy of telehealth services on the reduction of hospital readmission and mortality rates for COPD.

METHODS

We used a cross-sectional design to examine the association between hospital risk-adjusted readmission and mortality rates for COPD and hospital use of post-discharge telemonitoring (TM). Data for 777 hospitals were sourced from the Centers for Medicare & Medicaid Services and the American Hospital Association annual surveys. Propensity score matching using the kennel weights method was applied to calculate the weighted probability of being a hospital that offers post-discharge TM services.

RESULTS

Hospitals with post-discharge TM had about 34% significantly higher odds (adjusted odds ratio (AOR) = 1.34; 95% confidence interval (CI) 1.06-1.70) of 30-day COPD readmission and 33% significantly lower odds (AOR = 0.67; 95% CI 0.50-0.90) of 30-day COPD mortality compared to hospitals without post-discharge TM services.

DISCUSSION

Overall, hospitals that offer post-discharge TM services have seen an improvement in 30-day COPD mortality rates. However, those same hospitals have also experienced a significant increase in 30-day COPD readmissions. TM can potentially decrease mortality in patients recently admitted for acute exacerbation of COPD. The results provide further evidence that readmissions present a problematic assessment of health-care quality, as the need for readmission may or may not be directly related to the quality of care received while in hospital.

Care Quality for Patients with Chronic Obstructive Pulmonary Disease in the Readmission Penalty Era

Rationale: Chronic obstructive pulmonary disease (COPD) is the fifth-leading cause of admissions and third-leading cause of readmissions among U.S. adults. Recent policies instituted financial penalties for excessive COPD readmissions. Objectives: To evaluate changes in the quality of care for patients hospitalized for COPD after implementation of the Hospital Readmissions Reduction Program (HRRP). Methods: We conducted a retrospective cohort study of patients older than 40 years of age hospitalized for COPD across 995 U.S. hospitals (Premier Healthcare Database). Measurements and Main Results: Quality of care before and after HRRP implementation was measured via adherence to recommended inpatient care treatments for acute exacerbations of COPD (recommended care, nonrecommended care, "ideal care" [all recommended and no nonrecommended care]). We included 662,842 pre-HRRP (January 2010-September 2014) and 285,508 post-HRRP (October 2014-December 2018) admissions. Recommended care increased at a rate of 0.16% per month pre-HRRP and 0.01% per month post-HRRP (P < 0.001). Nonrecommended care decreased at a rate of 0.15% per month pre-HRRP and 0.13% per month post-HRRP. Ideal care increased at a rate of 0.24% per month pre-HRRP and 0.11% per month post-HRRP (P < 0.001). Conclusions: The pre-HRRP trends toward improving care quality for inpatient COPD care slowed after HRRP implementation. This suggests that financial penalties for readmissions did not stimulate higher quality of care for patients hospitalized with COPD. It remains unclear what policies or approaches will be effective to ensure high care quality for patients hospitalized with COPD exacerbations.

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.

Trial registration: This study was registered at Chinese Clinical Trial Registry under registration number of ChiCTR2200056241CTR2200056241.

Chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity, mortality, and health-care use worldwide. COPD is caused by exposure to inhaled noxious particles, notably tobacco smoke and pollutants. However, the broad range of factors that increase the risk of development and progression of COPD throughout the life course are increasingly being recognised. Innovations in omics and imaging techniques have provided greater insight into disease pathobiology, which might result in advances in COPD prevention, diagnosis, and treatment. Although few novel treatments have been approved for COPD in the past 5 years, advances have been made in targeting existing therapies to specific subpopulations using new biomarker-based strategies. Additionally, COVID-19 has undeniably affected individuals with COPD, who are not only at higher risk for severe disease manifestations than healthy individuals but also negatively affected by interruptions in health-care delivery and social isolation. This Seminar reviews COPD with an emphasis on recent advances in epidemiology, pathophysiology, imaging, diagnosis, and treatment.

Aligning mission to digital health strategy in academic medical centers

The strategies of academic medical centers arise from core values and missions that aim to provide unmatched clinical care, patient experience, research, education, and training. These missions drive nearly all activities. They should also drive digital health activities - and particularly now given the rapid adoption of digital health, marking one of the great transformations of healthcare; increasing pressures on health systems to provide more cost-effective care; the pandemic-accelerated funding and rise of well-funded new entrants and technology giants that provide more convenient forms of care; and a more favorable regulatory and reimbursement landscape to incorporate digital health approaches. As academic medical centers emerge from a pandemic-related reactionary digital health posture, where pressures to adopt more digital health technologies mount, a broad digital health realignment that leverages the strengths of such centers is required to accomplish their missions.

A systematic review of telehealth applications in hospital medicine

BACKGROUND

Despite the proliferation of telehealth, uptake for acute inpatient services has been slower. Hospitalist shortages in rural and critical access hospitals as well as the COVID-19 pandemic have led to a renewed interest in telehealth to deliver acute inpatient services. Understanding current evidence is crucial for promoting uptake and developing evidence-based practices.

OBJECTIVE

To conduct a systematic review of telehealth applications in acute inpatient general medicine and pediatric hospital wards and synthesize available evidence.

DATA SOURCES

A search of five databases (PubMed, CINAHL, Embase, Scopus, and ProQuest Theses, and Dissertations) using a combination of search terms including telemedicine and hospital medicine/inpatient care keywords yielded 17,015 citations.

STUDY SELECTION AND DATA EXTRACTION

Two independent coders determined eligibility based on inclusion and exclusion criteria. Data were extracted and organized into main categories based on findings: (1) feasibility and planning, (2) implementation and technology, and (3) telehealth application process and outcome measures.

RESULTS

Of the 20 publications included, three were feasibility and planning studies describing the creation of the program, services provided, and potential cost implications. Five studies described implementation and technology used, including training, education, and evaluation methods. Finally, twelve discussed process and outcome measures, including patient and provider satisfaction and costs.

CONCLUSION

Telehealth services for hospital medicine were found to be effective, well received, and initial cost estimates appear favorable. A variety of services were described across programs with considerable benefit appreciated by rural and smaller hospitals. Additional work is needed to evaluate clinical outcomes and overall program costs.

Does Telemedicine Promote Physical Activity?

Exercise capacity and physical activity are different concepts: the former refers to what an individual is capable of performing, while the latter refers to what the individual does in daily life. Low levels of physical activity (PA), which are very common in individuals with COPD, are associated with poor health outcomes, including increased symptoms, a more rapid decline in lung function, increased health care utilization and increased mortality risk. Because of these pervasive negative outcomes, attempts have been made to increase physical activity in individuals with COPD, hoping that success in this area will mitigate the negative effects of inactivity. Based on its ability to increase exercise capacity and reduce dyspnea in COPD and other chronic respiratory diseases, pulmonary rehabilitation (PR) would be expected also increase physical activity in these patients. However, accessibility to pulmonary rehabilitation programs is problematic in some areas, and studies testing its effectiveness in this outcome area have had inconsistent results. Using telehealth interventions using technology to provide medical care conveniently over a distance would have the benefit of reaching a larger proportion of individuals with COPD. A systematic review of clinical trials testing telehealth to promote physical activity had mixed results and low-certainty evidence, resulting in the inability to recommend any single type of intervention. Thus, using telehealth interventions to promote physical activity for individuals with chronic respiratory diseases, while promising, remains an area where future investigations are needed to identify its optimal modalities and clarify its benefits.

Will Remotely Based Pulmonary Rehabilitation Water Down Its Effectiveness?

Despite numerous benefits, traditional Pulmonary Rehabilitation (PR) as a resource remains underutilized in chronic lung disease. Less than 3% of eligible candidates for PR attend one or more sessions after hospitalization due to many barriers, including the ongoing COVID-19 pandemic. Emerging alternative models of PR delivery such as home-based PR, tele-rehabilitation, web-based PR, or hybrid models could help address these barriers. Numerous studies have tested the feasibility, safety, and efficacy of these methods, but there is wide variability across studies and methods. We conducted a literature review to help determine if these alternative delivery methods watered down the effectiveness of PR. To evaluate the effectiveness of remotely based PR, the authors performed a literature search for randomized controlled trials (RCTs), cohort studies, and case series using PubMed, CINAHL, and Medline to identify relevant articles through 1 May 2021. Twenty-six applicable studies were found in which 11 compared tele-rehabilitation to conventional clinic-based PR; 11 evaluated tele-rehabilitation using the patient’s baseline status as control; and four compared tele-rehabilitation to no rehabilitation. Despite the different technologies used across studies, tele-rehabilitation was found to be both a feasible and an efficacious option for select patients with lung disease. Outcomes across these studies demonstrated similar benefits to traditional PR programs. Thus the existing data does not show that remotely based PR waters down the effectiveness of conventional PR. Use of remotely based PR is a feasible and effective option to deliver PR, especially for patients with significant barriers to conventional clinic-based PR. Additional, well-conducted RCTs are needed to answer the questions regarding its efficacy, safety, cost-effectiveness and who, among patients with COPD and other lung diseases, will derive the maximum benefit.

Team VA Video Connect (VVC) to optimize mobility and physical activity in post-hospital discharge older veterans: baseline assessment

Background

Telehealth is increasingly used for rehabilitation and exercise but few studies include older adult participants with comorbidities and impairment, particularly cognitive. Using Veterans Administration Video Connect (VVC), the aim of the present study is to present the screening, recruitment, baseline assessment, and initial telehealth utilization of post-hospital discharge Veterans in a VVC home-telehealth based program to enhance mobility and physical activity.

Methods

Older adult Veterans (n = 45, mean age 73), recently discharged from the hospital with physical therapy goals, were VVC-assessed in self-report and performance-based measures, using test adaptations as necessary, by a clinical pharmacy specialist and social worker team.

Results

Basic and instrumental ADL disabilities were common as were low mobility (Short Portable Performance Battery) and physical activity levels (measured by actigraphy). Half had Montreal Cognitive Assessment (MoCA) scores in the mild cognitive impairment range (< 24). Over 2/3 of the participants used VA-supplied tablets. While half of the Veterans were fully successful in VVC, 1/3 of these and an additional group with at least one failed connection requested in-person visits for assistance. One-quarter had no VVC success and sought help for tablet troubleshooting, and half of these eventually “gave up” trying to connect; difficulty with using the computer and physical impairment (particularly dexterity) were described prominently in this group. On the other hand, Veterans with at least mild cognitive impairment (based on MoCA scores) were present in all connectivity groups and most of these used caregiver support to facilitate VVC.

Conclusions

Disabled older post-hospital discharged Veterans with physical therapy goals can be VVC-assessed and enrolled into a mobility/physical activity intervention. A substantial proportion required technical support, including in-person support for many. Yet, VVC seems feasible in those with mild cognitive impairment, assuming the presence of an able caregiver. Modifications of assessment tools were needed for the VVC interface, and while appearing feasible, will require further study.

The Accessibility, Feasibility, Safety of a Standardized Community-Based Tele-Pulmonary Rehab Program for COPD: A 3-Year Real-World Prospective Study

RATIONALE

Few individuals with COPD are able to access pulmonary rehabilitation (PR) despite its importance. Barriers include increased travel time and lack of resources. Tele-PR has been proposed as a novel solution to overcome such barriers and improve access.

OBJECTIVE

Our study aimed to provide information on implementing a novel province-wide standardized community-based tele-PR program and determine its accessibility, feasibility and safety. Secondary objectives examined the effectiveness of tele-PR compared to standard-PR and if clinical improvements were sustained over time.

METHODS

We conducted a concurrent prospective study of people with COPD enrolled in either standard-PR or community-based tele-PR at satellite centers between January 2017 and January 2020. To determine accessibility and feasibility, we recorded the number of participating centers meeting eligibility criteria, centers remaining in the program over 3 years, number of delivered programs and major adverse events. Participants had a 6MWT and CAT at baseline, immediately post-PR and at 1,3,6 and 12 months. Descriptive analysis was carried out for accessibility, feasibility and safety. Mixed-effects random models were used to estimate change in 6MWT and CAT.

RESULTS

Seven tele-sites were recruited into the tele-PR program with 6 continuing to participate at 3 years, delivering a total of 58 programs for 177 individuals with COPD. During that same period, the standard-PR site delivered 15 programs for 89 individuals with COPD. Over 70% of participants completed each program and no major adverse events were reported. There were significant improvements in the 6MWT and CAT scores in both groups immediately post-PR with no between-group differences. Participants in both programs had persistent 6MWT improvement at 1,3,6 and 12 months post-PR. Participants in tele-PR had persistent improvement of CAT scores but not in standard-PR beyond 1 month post-PR.

CONCLUSION

This study provides real-world evidence demonstrating successful implementation of tele-PR. The Canadian standardized tele-PR program is an accessible, feasible, safe and effective model for delivering PR.

Web-Based Self-management Program (SPACE for COPD) for Individuals Hospitalized With an Acute Exacerbation of Chronic Obstructive Pulmonary Disease: Nonrandomized Feasibility Trial of Acceptability

BACKGROUND

Hospital admissions due to the acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are costly for individuals and health services. Pulmonary rehabilitation (PR) is known to reduce hospital readmissions when delivered after hospitalization, but the uptake and completion of PR following hospitalization remains poor (<10% of those eligible in the UK audit data). A web-based platform of the SPACE (Self-management Program of Activity Coping and Education) for COPD (chronic obstructive pulmonary disease) has previously shown promising results in patients with stable COPD but has not been tested following an AECOPD.

OBJECTIVE

This study aims to assess the feasibility and acceptability of a web-based self-management program.

METHODS

A nonrandomized feasibility study for patients with confirmed AECOPD who were deemed web literate was conducted. All patients consented during their hospitalization and received access to the website following discharge in addition to usual care. The program aims to facilitate patients to better understand and manage their condition through education and home-based exercises. Participants were asked to complete the Bristol COPD Knowledge Questionnaire at baseline and after 6 months. A total of 14 participants were also interviewed (n=8 completers; n=6 noncompleters) regarding their experiences with the web-based program and trial. The interviews were analyzed using thematic analysis.

RESULTS

In total, 2080 patients were screened for eligibility, of which 100 patients (age: mean 71.2 years, SD 9.3 years; male: 55/100, 55%; forced expiratory volume in 1 second/forced vital capacity ratio: mean 0.46, SD 0.14; pack-years: mean 50.2, SD 31.0; current smokers: 35/100, 35%) were recruited (4.8% of those screened). The main reason for ineligibility was a lack of web literacy (1366/1980, 68.98%). In total, 18% (18/100) of patients had completed the web program by 6 months, with others still registered in the program (27/100, 27%), and more than half did not register (55/100, 55%). There was a mean change in Bristol COPD Knowledge Questionnaire scores at 6 months of 7.8 (SD 10.2) points. Qualitative interviews identified three main themes: preparing for, engagement with, and benefits of the study and program. A total of 57% (57/100) accepted a referral to PR on discharge and 19% (19/100) had completed the program after 6 months.

CONCLUSIONS

On the basis of the challenges of recruiting, retaining, and engaging participants in a web-based self-management program, it is not a feasible approach to roll out widely. This study acknowledges that this is a challenging time for patients with an AECOPD to engage in exercise and self-management education. However, for patients who were able to engage in such an intervention, the completion rate of PR was double the previous audit estimates from the United Kingdom, disease knowledge improved, and the intervention was of value to patients.

Feasibility of a Health Coaching and Home-Based Rehabilitation Intervention With Remote Monitoring for COPD

BACKGROUND

Pulmonary rehabilitation is an effective treatment for patients with COPD, but patient uptake and adherence to the current offering of center-based pulmonary rehabilitation is modest due to transportation, access, poverty, and frailty, and even more so in the context of the COVID pandemic. Home-based options have been proposed and were found noninferior to center-based rehabilitation; however, there is a lack of home-based programs, and more understanding is needed. We aimed to test the feasibility, uptake, and adherence to a home-based program for COPD rehabilitation with health coaching.

METHODS

We conducted a randomized trial with a wait-list controlled design to evaluate the effects of a home-based program with health coaching on breathlessness in subjects with moderate to severe COPD unable to attend the regular pulmonary rehabilitation program. The 8-week intervention consisted of video-guided exercises to be done 6 times a week and captured with a computer tablet. Health coaching was done weekly over the telephone to review subject activity and symptoms and to provide an opportunity for the subject to define their weekly goals. The primary outcomes were uptake, adherence, and Chronic Respiratory Questionnaire (CRQ) Dyspnea Domain. Secondary outcomes were self-management abilities and CRQ Emotions-Mastery-Fatigue.

RESULTS

154 subjects with moderate to severe COPD were randomized. Subject adherence was 86% to the proposed 6-times a week exercise routine. There (P = .062) was no significant difference in breathlessness (CRQ dyspnea). There was a significant improvement in self-management abilities (P < .001). The results of the qualitative interviews showed high levels of acceptability of the program.

CONCLUSIONS

The tested home-based rehabilitation program with health coaching was feasible, highly acceptable, showed a high degree of adherence, and improved self-management abilities. This study offers seminal information for home-based rehabilitation programs to design alternative options of rehabilitation to individuals with COPD that cannot attend to the well-established center-based pulmonary rehabilitation.

Technical Innovations in Pneumology: E-Health, Screening, Diagnostics, and Therapy

At the 2020 "Luftschlösser" (castles in the air) conference, experts from a wide range of pneumological fields discussed technical innovations in pneumology, which can be seen in many different areas of the field, including e-health, screening, diagnostics, and therapy. They contribute to substantial advancements ranging from the innovative use of diagnostic tools to novel treatments for chronic lung diseases. Artificial intelligence enables broader screening, which can be expected to have beneficial effects on disease progression and overall prognosis. There is still a high demand for clinical trials to investigate the usefulness and risk-benefit ratio. Open questions remain especially about the quality and utility of medical apps in an inadequately regulated market. This article weighs the pros and cons of technical innovations in specific subspecialties of pneumology based on the lively exchange of ideas among various pneumological experts.

Defining Modern Pulmonary Rehabilitation. An Official American Thoracic Society Workshop Report

Pulmonary rehabilitation is a highly effective treatment for people with chronic lung disease but remains underused across the world. Recent years have seen the emergence of new program models that aim to improve access and uptake, including telerehabilitation and low-cost, home-based models. This workshop was convened to achieve consensus on the essential components of pulmonary rehabilitation and to identify requirements for successful implementation of emerging program models. A Delphi process involving experts from across the world identified 13 essential components of pulmonary rehabilitation that must be delivered in any program model, encompassing patient assessment, program content, method of delivery, and quality assurance, as well as 27 desirable components. Only those models of pulmonary rehabilitation that have been tested in clinical trials are currently considered as ready for implementation. The characteristics of patients most likely to succeed in each program model are not yet known, and research is needed in this area. Health professionals should use clinical judgment to determine those patients who are best served by a center-based, multidisciplinary rehabilitation program. A comprehensive patient assessment is critical for personalization of pulmonary rehabilitation and for effectively addressing individual patient goals. Robust quality-assurance processes are important to ensure that any pulmonary rehabilitation service delivers optimal outcomes for patients and health services. Workforce capacity-building and training should consider the skills necessary for emerging models, many of which are delivered remotely. The success of all pulmonary rehabilitation models will be judged on whether the essential components are delivered and on whether the expected patient outcomes, including improved exercise capacity, reduced dyspnea, enhanced health-related quality of life, and reduced hospital admissions, are achieved.

Telemedicine in the management of patients with chronic respiratory failure

Patients with chronic respiratory failure are often required to attend multiple hospital appointments, which may be difficult due to their physical disabilities and the amount of equipment they are required to bring. Their caregivers often struggle with the lack of immediate care available when the patient suffers difficulties at home. Telemedicine is an opportunity to bridge the gap between home and healthcare professionals by allowing the healthcare team to reach into patients' homes to provide more frequent support. The evidence for the use of telemedicine in patients with chronic respiratory failure remains equivocal. Although the uptake of telemedicine has been slow, the SARS-CoV-2 pandemic has resulted in the rapid dissemination of telemedicine to allow the delivery of care to vulnerable patients while reducing the need for their attendance in hospital. Logistical and legal challenges to the delivery of telemedicine remain, but the pandemic may serve as a driver to ameliorate these challenges and facilitate wider use of this technology to improve the experience of patients with chronic respiratory failure.

Educational aims

To provide an overview of the rationale for delivering care via telemedicine for patients with chronic respiratory failure.To provide the evidence base for establishing a telemedicine service.To highlight the potential opportunities and challenges in delivering a telemedicine service for patients with chronic respiratory failure.

Telerehabilitation in Subjects With Respiratory Disease: A Scoping Review

Considering the current coronavirus disease (COVID-19) pandemic, telerehabilitation may be a viable first-line option for patients with respiratory tract disease. To date, there has been no systematic review on telerehabilitation for respiratory tract diseases, including COVID-19. Therefore, this scoping review aimed to determine what telerehabilitation for patients with respiratory tract diseases consists of, how safe telerehabilitation is for patients with respiratory tract diseases, and how feasible telerehabilitation is for hospitalized patients with COVID-19. In May 2020, we conducted a search of the following publication databases on the use of telerehabilitation in the treatment of respiratory tract diseases: Medical Literature Analysis and Retrieval System Online, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Literature, and Physiotherapy Evidence Database. Of the 208 articles identified, 23 studies were subsequently included in this scoping review. In 22 of the included studies, subjects had stable COPD and underwent telerehabilitation at home. The final included study was a case series of subjects with severe acute respiratory syndrome coronavirus 2 infection who underwent telerehabilitation in-hospital. Most telerehabilitation programs consisted of aerobic exercises using a cycle ergometer or a treadmill, walking, and muscle-strengthening exercises. The reported number of adverse events was low, and most studies reported that the average session adherence rate was > 70%. The majority of the telerehabilitation programs included a face-to-face rehabilitation assessment. Our findings indicate that, in its current state, telerehabilitation may be safe and feasible and may lead to reduced face-to-face rehabilitation therapy; in addition, remote rehabilitation assessment should be considered during the COVID-19 pandemic. Further research that targets a more diverse range of respiratory tract diseases and considers telerehabilitation in a hospital setting is required.

Telerehabilitation for chronic respiratory disease

BACKGROUND

Pulmonary rehabilitation is a proven, effective intervention for people with chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD) and bronchiectasis. However, relatively few people attend or complete a program, due to factors including a lack of programs, issues associated with travel and transport, and other health issues. Traditionally, pulmonary rehabilitation is delivered in-person on an outpatient basis at a hospital or other healthcare facility (referred to as centre-based pulmonary rehabilitation). Newer, alternative modes of pulmonary rehabilitation delivery include home-based models and the use of telehealth. Telerehabilitation is the delivery of rehabilitation services at a distance, using information and communication technology. To date, there has not been a comprehensive assessment of the clinical efficacy or safety of telerehabilitation, or its ability to improve uptake and access to rehabilitation services, for people with chronic respiratory disease.

OBJECTIVES

To determine the effectiveness and safety of telerehabilitation for people with chronic respiratory disease.

SEARCH METHODS

We searched the Cochrane Airways Trials Register, and the Cochrane Central Register of Controlled Trials; six databases including MEDLINE and Embase; and three trials registries, up to 30 November 2020. We checked reference lists of all included studies for additional references, and handsearched relevant respiratory journals and meeting abstracts.

SELECTION CRITERIA

All randomised controlled trials and controlled clinical trials of telerehabilitation for the delivery of pulmonary rehabilitation were eligible for inclusion. The telerehabilitation intervention was required to include exercise training, with at least 50% of the rehabilitation intervention being delivered by telerehabilitation.

DATA COLLECTION AND ANALYSIS

We used standard methods recommended by Cochrane. We assessed the risk of bias for all studies, and used the ROBINS-I tool to assess bias in non-randomised controlled clinical trials. We assessed the certainty of evidence with GRADE. Comparisons were telerehabilitation compared to traditional in-person (centre-based) pulmonary rehabilitation, and telerehabilitation compared to no rehabilitation. We analysed studies of telerehabilitation for maintenance rehabilitation separately from trials of telerehabilitation for initial primary pulmonary rehabilitation.

MAIN RESULTS

We included a total of 15 studies (32 reports) with 1904 participants, using five different models of telerehabilitation. Almost all (99%) participants had chronic obstructive pulmonary disease (COPD). Three studies were controlled clinical trials. For primary pulmonary rehabilitation, there was probably little or no difference between telerehabilitation and in-person pulmonary rehabilitation for exercise capacity measured as 6-Minute Walking Distance (6MWD) (mean difference (MD) 0.06 metres (m), 95% confidence interval (CI) -10.82 m to 10.94 m; 556 participants; four studies; moderate-certainty evidence). There may also be little or no difference for quality of life measured with the St George's Respiratory Questionnaire (SGRQ) total score (MD -1.26, 95% CI -3.97 to 1.45; 274 participants; two studies; low-certainty evidence), or for breathlessness on the Chronic Respiratory Questionnaire (CRQ) dyspnoea domain score (MD 0.13, 95% CI -0.13 to 0.40; 426 participants; three studies; low-certainty evidence). Participants were more likely to complete a program of telerehabilitation, with a 93% completion rate (95% CI 90% to 96%), compared to a 70% completion rate for in-person rehabilitation. When compared to no rehabilitation control, trials of primary telerehabilitation may increase exercise capacity on 6MWD (MD 22.17 m, 95% CI -38.89 m to 83.23 m; 94 participants; two studies; low-certainty evidence) and may also increase 6MWD when delivered as maintenance rehabilitation (MD 78.1 m, 95% CI 49.6 m to 106.6 m; 209 participants; two studies; low-certainty evidence). No adverse effects of telerehabilitation were noted over and above any reported for in-person rehabilitation or no rehabilitation.

AUTHORS' CONCLUSIONS

This review suggests that primary pulmonary rehabilitation, or maintenance rehabilitation, delivered via telerehabilitation for people with chronic respiratory disease achieves outcomes similar to those of traditional centre-based pulmonary rehabilitation, with no safety issues identified. However, the certainty of the evidence provided by this review is limited by the small number of studies, of varying telerehabilitation models, with relatively few participants. Future research should consider the clinical effect of telerehabilitation for individuals with chronic respiratory diseases other than COPD, the duration of benefit of telerehabilitation beyond the period of the intervention, and the economic cost of telerehabilitation.

Development of Respercise® a Digital Application for Standardizing Home Exercise in COPD Clinical Trials

Background

Pulmonary rehabilitation (PR) is an important therapy for patients with chronic obstructive pulmonary disease (COPD), yet uptake remains low. Intervention strategies which recapitulate the benefits of PR are, therefore, needed and digital, home-based therapies present opportunity in this space. Digital therapies also potentially offer an opportunity to standardize PR in clinical trials for new COPD therapies.

Aims and Methods

We aimed to create a digital application (app), Respercise^®, consisting of up to 4 strengthening exercises in conjunction with Therbands™ and a daily physical activity program with individualized step goals, and to test its feasibility in a clinical trial. App usability was surveyed qualitatively before development iterations and deployment in a 13-week interventional clinical trial. All participants who completed the study were invited for an exit interview and performed the 5-repetition sit-to-stand test amongst other measures.

Results

Feedback from clinical trial participants was positive; 97% of respondents liked the app. A total of 88% of participants reported that it was easy to fit the exercises into their daily routine, and there was over 90% adherence for entering daily step counts. Notably, on day 90 both females and males using Respercise alone demonstrated a 2.22- and 2.27-seconds improvement in time for 5-repetition sit-to-stand tests respectively, above the 1.7 second threshold that is considered clinically meaningful in COPD.

Conclusions

Respercise can be successfully deployed in clinical trials, offering the opportunity for standardization of exercise in clinical trials and, with further development, could have wider reach as a home-based intervention for individuals with COPD.

Providing Outpatient Telehealth Services in the United States: Before and During Coronavirus Disease 2019

Before coronavirus disease 2019 (COVID-19), telehealth evaluation and management (E/M) services were not widely used in the United States and often were restricted to rural areas or locations with poor access to care. Most Medicare beneficiaries could not receive telehealth services in their homes. In response to the COVID-19 pandemic, Medicare, Medicaid, and commercial insurers relaxed restrictions on both coverage and reimbursement of telehealth services. These changes, together with the need for social distancing, transformed the delivery of outpatient E/M services through an increase in telehealth use. In some cases, the transition from in-person outpatient care to telehealth occurred overnight. Billing and claim submission for telehealth services is complicated; has changed over the course of the pandemic; and varies with each insurance carrier, making telehealth adoption burdensome. Despite these challenges, telehealth is beneficial for health-care providers and patients. Without additional legislation at the federal and state levels, it is likely that telehealth use will continue to decline after the COVID-19 public health emergency.

Defining Chronic Mucus Hypersecretion Using the CAT in the SPIROMICS Cohort

Background

Chronic cough and phlegm are frequently reported chronic obstructive pulmonary disease (COPD) symptoms. Prior research classified chronic mucus hypersecretion (CMH) based on the presence of these symptoms for ≥3 months, called chronic bronchitis (CB) if respiratory infection symptoms were present for 1–2 years (Medical Research Council [MRC] definition). We explored whether the COPD Assessment Test (CAT), a simple measure developed for routine clinical use, captures CMH populations and outcomes similarly to MRC and St. George’s Respiratory Questionnaire (SGRQ) definitions.

Methods

We identified CMH in the SPIROMICS COPD cohort using (a) MRC definitions, (b) SGRQ questions for cough and phlegm (both as most/several days a week), and (c) CAT cough and phlegm questions. We determined optimal cut-points for CAT items and described exacerbation frequencies for different CMH definitions. Moderate exacerbations required a new prescription for antibiotics/oral corticosteroids or emergency department visit; severe exacerbations required hospitalization. Results were stratified by smoking status.

Results

In a population of 1431 participants (57% male; mean FEV₁% predicted 61%), 47% and 49% of evaluable participants had SGRQ- or CAT-defined CMH, respectively. A cut-point of ≥2 for cough and phlegm items defined CMH in CAT. Among SGRQ-CMH+ participants, 80% were also defined as CMH+ by the CAT. CMH+ participants were more likely to be current smokers. A higher exacerbation frequency was observed for presence of CMH+ versus CMH− in the year prior to baseline for all CMH definitions; this trend continued across 3 years of follow-up, regardless of smoking status.

Conclusion

Items from the CAT identified SGRQ-defined CMH, a frequent COPD trait that correlated with exacerbation frequency. The CAT is a short, simple questionnaire and a potentially valuable tool for telemedicine or real-world trials. CAT-based CMH is a novel approach for identifying clinically important characteristics in COPD that can be ascertained in these settings.

[Technological Innovations in Pulmonology - Examples from Diagnostics and Therapy]

A significant proportion of the current technological developments in pneumology originate from the various areas of information technology. The spectrum ranges from smartphone apps to be used in daily life or in patient care to the use of artificial intelligence in screening and early detection of diseases. The diagnostic accuracy of apps for symptom analysis is currently very limited. Research projects are performed on the integration of symptoms and functional parameters into early detection, but also on mobility measurements as a prognostic marker in COPD. Lung cancer screening using computed tomography represents a major challenge. Here, artificial intelligence can help radiologists to cope with huge amounts of data. However, the quality of the software depends on the sufficient training of the system. Technological developments shape all fields of pneumology. For diagnostic and interventional endoscopy, they offer improved biopsy techniques and microstructural imaging. Advances in lung function measurements allow the differentiated analysis of respiratory mechanical disorders, and they could be transferred to ventilation technology. The translation of basic findings about the lung microbiome into patient care may perspectively help to better understand and treat COPD exacerbations.

ENABLING THE UTILIZATION OF POTENTIALLY DISRUPTIVE DIGITAL INNOVATIONS BY INCUMBENTS: THE IMPACT OF CONTEXTUAL, ORGANISATIONAL, AND INDIVIDUAL FACTORS IN REGULATED CONTEXTS

Incumbents’ inertia in the face of disruptive innovations has been emphasised in prior literature. The relevance of inertia is particularly topical in the context of digital transformation. However, incumbents may be able to invest in disruptive digital innovations appropriately if they possess the motivation and ability to do so. In this paper, I use three streams of research in order to investigate contextual, organisational, and individual antecedents of incumbents’ motivation and ability to adopt and use potentially disruptive digital innovations in health care: institutional theory, the resource-based view, and technology acceptance literature. I employ factor analyses and logistic regressions to test the impact on the adoption and usage of telemedicine applications using a dataset of 9,196 European general practitioners. I examine B2B as well as B2C applications in order to determine the effect of the antecedents on different business models. My findings suggest that only isomorphic pressure, complementary assets, and perceived output quality significantly influence both adoption and usage as well as B2B and B2C business models in the same way. Formal institutions and individual factors yield ambiguous results. These findings provide important implications for the understanding of incumbents’ response to potentially disruptive digital innovations in regulated contexts.

Recent Advances in the Management of Acute Exacerbations of Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease is a chronic, irreversible obstructive lung disease that results from exposure to noxious stimuli. Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) usually result from viral or bacterial respiratory infections, but may also result from exposure to environmental pollution. AECOPD are associated with functional decline, increased risk of subsequent exacerbations, and death. Despite the poor prognosis of AECOPD, patients are empowered through self-management programs in their battle against this lethal disease. Morbidity and mortality of chronic obstructive pulmonary disease hospitalizations are reduced by implementing standardized treatment modalities outlined in this article throughout the hospitalization and beyond.

Medical Director Responsibilities for Outpatient Pulmonary Rehabilitation Programs in the United States: 2019: A STATEMENT FOR HEALTH CARE PROFESSIONALS FROM THE AMERICAN ASSOCIATION OF CARDIOVASCULAR AND PULMONARY REHABILITATION (AACVPR)

Clinical guidelines have been developed recognizing pulmonary rehabilitation (PR) as a key component in the management of patients with chronic lung disease. The medical director of a PR program is a key player in every program and is a requirement for operation of the program. The medical director must be a licensed physician who has experience in respiratory physiology management. The purpose of this document is to provide an update regarding the clinical, programmatic, legislative, and regulatory issues that impact PR medical directors in North America. It describes the clinical rationale for physician involvement, relevant legislative and regulatory requirements, and resources available that the medical director can utilize to promote evidence-based and cost-effective PR services. All pulmonary rehabilitation (PR) programs must include a medical director. There are many clinical, programmatic, legislative, and regulatory issues that impact the PR medical director. The purpose of this document is to concentrate on the unique roles and responsibilities of the PR medical director.

Risk assessment for hospital admission in patients with COPD; a multi-centre UK prospective observational study

In chronic obstructive pulmonary disease (COPD), acute exacerbation of COPD requiring hospital admission is associated with mortality and healthcare costs. The ERICA study assessed multiple clinical measures in people with COPD, including the short physical performance battery (SPPB), a simple test of physical function with 3 components (gait speed, balance and sit-to-stand). We tested the hypothesis that SPPB score would relate to risk of hospital admissions and length of hospital stay. Data were analysed from 714 of the total 729 participants (434 men and 280 women) with COPD. Data from this prospective observational longitudinal study were obtained from 4 secondary and 1 tertiary centres from England, Scotland, and Wales. The main outcome measures were to estimate the risk of hospitalisation with acute exacerbation of COPD (AECOPD and length of hospital stay derived from hospital episode statistics (HES). In total, 291 of 714 individuals experienced 762 hospitalised AECOPD during five-year follow up. Poorer performance of SPPB was associated with both higher rate (IRR 1.08 per 1 point decrease, 95% CI 1.01 to 1.14) and increased length of stay (IRR 1.18 per 1 point decrease, 95% CI 1.10 to 1.27) for hospitalised AECOPD. For the individual sit-to-stand component of the SPPB, the association was even stronger (IRR 1.14, 95% CI 1.02 to 1.26 for rate and IRR 1.32, 95% CI 1.16 to 1.49 for length of stay for hospitalised AECOPD). The SPPB, and in particular the sit-to-stand component can both evaluate the risk of H-AECOPD and length of hospital stay in COPD. The SPPB can aid in clinical decision making and when prioritising healthcare resources.

Assess the Performance and Cost-Effectiveness of LACE and HOSPITAL Re-Admission Prediction Models as a Risk Management Tool for Home Care Patients: An Evaluation Study of a Medical Center Affiliated Home Care Unit in Taiwan

The LACE index and HOSPITAL score models are the two most commonly used prediction models identifying patients at high risk of readmission with limited information for home care patients. This study compares the effectiveness of these two models in predicting 30-day readmission following acute hospitalization of such patients in Taiwan. A cohort of 57 home care patients were enrolled and followed-up for one year. We compared calibration, discrimination (area under the receiver operating curve, AUC), and net reclassification improvement (NRI) to identify patients at risk of 30-day readmission for both models. Moreover, the cost-effectiveness of the models was evaluated using microsimulation analysis. A total of 22 readmissions occurred after 87 acute hospitalizations during the study period (readmission rate = 25.2%). While the LACE score had poor discrimination (AUC = 0.598, 95% confidence interval (CI) = 0.488–0.702), the HOSPITAL score achieved helpful discrimination (AUC = 0.691, 95% CI = 0.582–0.785). Moreover, the HOSPITAL score had improved the risk prediction in 38.3% of the patients, compared with the LACE index (NRI = 0.383, 95% CI = 0.068–0.697, p = 0.017). Both prediction models effectively reduced readmission rates compared to an attending physician’s model (readmission rate reduction: LACE, 39.2%; HOSPITAL, 43.4%; physician, 10.1%; p < 0.001). The HOSPITAL score provides a better prediction of readmission and has potential as a risk management tool for home care patients.
