Effect of Physical Activity Coaching on Acute Care and Survival Among Patients With Chronic Obstructive Pulmonary Disease: A Pragmatic Randomized Clinical Trial

Physical Activity Interventions Among Older Adults with Chronic Illnesses: Systematic Review and Network Meta-Analysis

To investigate the individual effectiveness of motivational interviewing, tailor-made interventions, social context-related interventions, shared decision making, and monitoring & feedback versus active- and passive control groups on physical activity level among older adults at short-, middle-, and long term. Secondary aim is to compare the effectiveness of interventions using a single motivational strategy versus interventions combining multiple motivational strategies. Literature search of PubMed, EMBASE, CINAHL, and PEDro databases using keywords and subject headings. Randomized controlled trials comparing two or more arms, with one arm focused on motivational strategies influencing physical activity were included. We identified 20,690 titles, of which 51 (comprising 11,596 participants) were included. Methodological quality and quality of evidence was evaluated using PEDro scale and GRADE approach. Outcomes were physical activity levels measured by objective- or subjective instruments at 3-, 6-, and 12 months follow-up. Standardized mean differences between intervention- and control groups were used as the mode of the analyses. For primary outcome, 6 months follow-up, pooled data demonstrated a statistically significant trend for higher effectiveness interventions using multiple motivational strategies compared with an active control intervention, while other singular motivational strategies did not show similar results for this comparison. The quality of the body of evidence was graded as very low for all motivational strategies. In our search, we have used broad in- and exclusion criteria for eligible studies regarding population characteristics resulting in a wide variety of conditions and illnesses included in our review which warrants a better representation of daily clinical practice. However, this led to data being pooled from a wide variety of different study populations and settings, content of interventions and outcome measures, increasing the heterogeneity of study characteristics. Interventions combining multiple motivational strategies show a trend to be more effective than using singular treatment strategies, although the optimal composition remains unclear.

The impact of health and wellness coaching on patient-important outcomes in chronic illness care: A systematic review and meta-analysis

BACKGROUND

Health and Wellness Coaching (HWC) may be beneficial in chronic condition care. We sought to appraise its effectiveness on quality of life (QoL), self-efficacy (SE), depression, and anxiety.

METHODS

We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane CENTRAL for randomized trials published January 2005 - March 2023 that compared HWC to standard clinical care or another intervention without coaching. We examined QoL, SE, depression, or anxiety outcomes. Meta-analysis utilizing the random-effects model was used to estimate the pooled standardized mean difference (SMD).

RESULTS

Thirty included studies demonstrated that HWC improved QoL within 3 months (SMD 0.62 95 % CI 0.22-1.02, p = 0.002), SE within 1.5 months (SMD 0.38, 95 % CI 0.03-0.73, p = 0.03), and depression at 3, 6, and 12 months (SMD 0.67, 95 % CI 0.13-1.20, p = 0.01), (SMD 0.72, 95 % CI 0.19-1.24, p = 0.006), and (SMD 0.41, 95 % CI 0.09-0.73, p = 0.01) Certainty in the evidence for most outcomes was either very low or low primarily due to the high risk of bias, heterogeneity, and imprecision.

CONCLUSION

HWC improves QoL, SE, and depression across chronic illness populations. Future research needs to standardize intervention reporting and outcome collection.

PRACTICE IMPLICATIONS

Future HWC studies should standardize intervention components, reporting, and outcome measures, apply relevant chronic illness theories, and aim to follow participants for greater than one year.

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.

Promotion of physical activity after hospitalization for COPD exacerbation: A randomized control trial

BACKGROUND AND OBJECTIVE

Physical activity worsens during exacerbations of chronic obstructive pulmonary disease (COPD) and notably after hospitalizations. Pedometer-based interventions are useful to increase physical activity in stable patients with COPD. However, there is little information concerning the implementation of such programs following severe exacerbation. This study assessed the efficacy of a physical activity program after hospitalization for a COPD exacerbation.

METHODS

We performed a prospective, 12-week, parallel group, assessor-blinded, randomized control trial in COPD patients hospitalized for an exacerbation. After discharge, physical activity and other secondary variables were assessed. Patients were allocated (1:1) to a physical activity promotion program (intervention group, IG) or usual care (control group, CG). Based on a motivational interview and accelerometer physical activity assessment, a patient-tailored, pedometer-based, progressive and target-driven program was designed. Linear mixed effect models were used to analyse between-group differences.

RESULTS

Forty-six out of 61 patients recruited were randomized and 43 (IG = 20, CG = 23) completed the study. In-hospital and baseline characteristics were similar in both groups. After 12 weeks of intervention, the mean steps difference between groups was 2093 steps/day, p = 0.018, 95% CI 376-4012, favouring the IG. Only the IG significantly increased the number of steps/day compared to baseline (mean difference [95% CI] 2932 [1069-4795] steps; p = 0.004). There were no other between-group differences.

CONCLUSION

After hospitalization for a COPD exacerbation, a patient-tailored physical activity program based on a motivational interview and the use of pedometers, with progressive and customized targets, improved the number of steps/day.

Protocol for a feasibility randomized trial of self-management support for people with chronic obstructive pulmonary disease using lay health coaches

Challenges with self-management are a major contributor to poor outcomes among adults with chronic obstructive pulmonary disease (COPD). The causes of poor self-management in COPD are manifold, and they arise from physical, cognitive, socioeconomic, environmental and societal sources. To address this complexity, we developed the Supporting self-Management Behaviors in Adults with COPD (SaMBA-COPD) model, which uses lay health coaches to identify a patient's barriers to effective COPD self-management and provide tailored support to help them overcome those barriers, reduce their symptoms and need for urgent care and improve their quality of life. The 6-month intervention includes referral of patients to a pharmacist for prescription of antibiotic and oral steroid "rescue packs" and support for a structured home exercise routine. All interactions of coaches and patients will take place by telephone or video call. We will test the feasibility and preliminary efficacy of SaMBA-COPD in a trial of 58 patients randomized 1:1 to the intervention or a COPD education control. Outcomes will be assessed at 6 and 9 months. Data from the trial will be used to inform the design of a fully powered, multi-site randomized trial of the intervention.

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.

Innovative Strategies to Facilitate Patient-Centered Research in Multiple Chronic Conditions

Multiple chronic conditions (MCC) are one of today's most pressing healthcare concerns, affecting 25% of all Americans and 75% of older Americans. Clinical care for individuals with MCC is often complex, condition-centric, and poorly coordinated across multiple specialties and healthcare services. There is an urgent need for innovative patient-centered research and intervention development to address the unique needs of the growing population of individuals with MCC. In this commentary, we describe innovative methods and strategies to conduct patient-centered MCC research guided by the goals and objectives in the Department of Health and Human Services MCC Strategic Framework. We describe methods to (1) increase the external validity of trials for individuals with MCC; (2) study MCC epidemiology; (3) engage clinicians, communities, and patients into MCC research; and (4) address health equity to eliminate disparities.

The Maugeri daily activity profile: a tool to assess physical activity in patients with chronic obstructive pulmonary disease

Patients with chronic obstructive pulmonary disease (COPD) report reduced physical activity (PA). There are only few tools available to assess PA and sedentary behavior in these patients, and none of them aims to differentiate between sedentary and active patterns. The aim of the study was to evaluate an easy tool to profile daily activity time in a cohort of patients with COPD, compared to healthy subjects; the study was set at the Istituti Clinici Scientifici Maugeri (ICS), IRCCS of Tradate and Lumezzane, Italy, and at the Ente Ospedaliero Cantonale Novaggio, Switzerland (Italian Speaking). The populations were inpatients with COPD, healthy subjects. The items of the Maugeri Daily Activity (MaDA) profile were chosen based on literature, interviews with patients and health professionals. Time spent during sleep (ST), when awake (AT), active (ACT) or in sedentary behavior (SET) were recorded. Lung function tests, arterial blood gases, the modified Medical Research Council (mMRC), the six-minute walking distance test (6MWD), the COPD Assessment Test (CAT), and the body-mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index were also assessed in patients. Sixty patients with COPD and 60 healthy controls filled in the questionnaire. As compared to controls, patients showed longer AT and SET. Active time of patients was significantly correlated with mMRC, CAT, Bode Index and 6MWD, but not with demographics, anthropometrics or stages of disease. Using this tool, we found that patients with COPD spent longer time awake and in sedentary behavior. The MaDA may be useful to evaluate PA in patients with COPD.

Estimating and testing an index of bias attributable to composite outcomes in comparative studies

OBJECTIVES

This study aimed to develop an index to evaluate the bias attributable to composite outcomes (BACOs) in comparative clinical studies.

STUDY DESIGN AND SETTING

The author defined the BACO index as the ratio of the logarithm of the association measure (e.g., relative risk) of the composite outcome to that of its most relevant component endpoint (e.g., mortality). Methods to calculate the confidence intervals and test the null hypotheses (BACO index = 1) were described and applied in systematically selected clinical trials. Two other preselected trials were included as "positive controls" for being examples of primary composite outcomes disregarded because of inconsistency with the treatment effect on mortality.

RESULTS

The BACO index values different from 1 were classified according to whether the use of composite outcomes overestimated (BACO index >1), underestimated (BACO index between 0 and <1), or inverted (BACO index <0) the association between exposure and prognosis. In 3 of 23 systematically selected trials and the two positive controls, the BACO indices were significantly lower than 1 (P < 0.005).

CONCLUSION

BACO index can warn that the composite outcome association is stronger, weaker, or even opposite than that of its most critical component.

Embedded Research in the Learning Healthcare System: Ongoing Challenges and Recommendations for Researchers, Clinicians, and Health System Leaders

Embedded research is an innovative means to improve performance in the learning healthcare system (LHS). However, few descriptions of successful embedded research programs have been published. In this perspective, we describe the Care Improvement Research Team, a mature partnership between researchers and clinicians at Kaiser Permanente Southern California. The program supports a core team of researchers and staff with dedicated resources to partner with health system leaders and practicing clinicians, using diverse methods to identify and rectify gaps in clinical practice. For example, recent projects helped clinicians to provide better care by reducing prescribing of unnecessary antibiotics for acute sinusitis and by preventing readmissions among the elderly. Embedded in operational workgroups, the team helps formulate research questions and enhances the rigor and relevance of data collection and analysis. A recent business-case analysis cited savings to the organization of over $10 million. We conclude that embedded research programs can play a key role in fulfilling the promise of the LHS. Program success depends on dedicated funding, robust data systems, and strong relationships between researchers and clinical stakeholders. Embedded researchers must be responsive to health system priorities and timelines, while clinicians should embrace researchers as partners in problem solving.

Methods to identify and prioritize research projects and perform embedded research in learning healthcare systems

BACKGROUND

The Embedded Healthcare Research Conference aimed to promote and enhance research-operations partnerships in diverse health care settings. Within this conference, the Priorities and Methods Workgroup set out to define a vision of embedded research that leverages diverse methods to address clearly articulated research questions of importance to health systems.

METHODS

The Workgroup session involved a combination of small and large group discussions around three broadly focused topics: the integration of embedded research within the existing quality improvement (QI) ecosystem; the identification, prioritization and formulation of embedded research questions; the creation of an embedded research "tool kit."

RESULTS

Workgroup participants envisioned a future for embedded research that is characterized by authentic engagement between researchers and health system leaders; seamless integration between research, QI and clinical operations; clear and explicit articulation of research questions; an appropriate balance between rigor and relevance in applied methodology; alignment between study design, available resources and the importance of the knowledge to be gained; efficient processes; and bi-directional communication. Important barriers to achieving this vision include limited access to executive leaders, silos that discourage integration of research and QI, generally low tolerance for disruption in high-risk clinical settings, limited access to data, and limited availability of researchers with requisite skills and training.

CONCLUSIONS

Embedded research holds potential to enhance the relevance, value and use of research, while also creating generalizable knowledge. Key recommendations include building authentic relationships, discouraging silos, encouraging innovation and experimentation, and expanding opportunities for funding research in delivery systems.
