Effect of counselling during pulmonary rehabilitation on self-determined motivation towards physical activity in people with chronic obstructive pulmonary disease – protocol of a mixed methods study

Background: Physical activity promotion in people with Chronic Obstructive Pulmonary Disease (COPD) is focus of research and public health. Patient-centred interventions like counselling are promising approaches to help patients reducing sedentary behaviour. Aim of the present study is to investigate if a physical activity counselling program during pulmonary rehabilitation increases physical activity level in daily life in people with COPD. Methods: A two-armed, single blind randomised controlled trial including 56 people with COPD will be conducted in an outpatient pulmonary rehabilitation. Patients will participate in a 12-week-rehabilitation program; individuals randomized to the interventional group will additionally participate in five counselling sessions with a physiotherapist, based on the principles of motivational interviewing. The participants’ physical activity level will be measured using an accelerometer (SenseWear Pro®) before, directly and 3 months after pulmonary rehabilitation. Semi-structured interviews will be conducted to learn more about barriers and facilitators regarding daily physical activity. Discussion: If the strategy successfully improves the physical activity level in people with COPD, counselling might be implemented in pulmonary rehabilitation

The influence of pulmonary rehabilitation and counselling on perceptions of physical activity in individuals with COPD : a qualitative study

Objective: The aim of this study was to explore to what extent a combined counselling and pulmonary rehabilitation program (PR) influences the perception of physical activity (PA) and motivation for behavioral change in PA in individuals with COPD. The results of previous quantitative trial that investigated the effect of this combined treatment on daily PA were inconclusive. It is conjectured that a more targeted tailoring of the counselling and PR intervention could improve its effectiveness. Patients and Methods: Eighteen individuals with COPD (median age 69, 8 females) who had participated in the PneumoReha program were interviewed twice (following PR and at three-month follow-up). These interviews were transcribed and analyzed thematically. Based on the codes thus identified, three categories ‘perception of PA intensity’, ‘quality of motivation to perform PA’, and ‘strategies to cope with barriers’ were used to differentiate ‘types’ of participants. Results: Four different types of COPD individuals were distinguished. Study findings indicate that those individuals who participated in the PR program combined with embedded counselling tended to be more active and intrinsically motivated. Conclusion: A typology of four types of people with COPD was developed, characterized by their perception of activity, individual motivation and strategies for managing barriers. The patients’ physical activity level might be influenced by their concept of physical activity and the quality of motivation. Recognizing patients’ different activity behaviors is important for improving the quality of outpatient PR programs and developing tailored (according to each type) counselling interventions embedded in outpatient PR programs. Clinical Trial Registration: The study was registered on the website of https://www.clinicaltrials.gov/ with the identifier NCT02455206 (27/05/2015), as well as on the Swiss National Trails Portal SNCTP000001426 (05/21/2015)

Effect of counselling during pulmonary rehabilitation on self-determined motivation to be physically active for people with chronic obstructive pulmonary disease : a pragmatic RCT

Background: Counselling is considered to be a promising approach to increasing physical activity (PA) in people with chronic obstructive pulmonary disease (COPD). The aim of the current study was to investigate whether a PA counselling program for people with COPD, when embedded in a comprehensive outpatient pulmonary rehabilitation (PR) program, increased their daily PA. Methods: A two-armed, single blind randomized controlled trial was conducted as a component of a 12-week outpatient pulmonary rehabilitation program. The participants randomized into the intervention group received five counselling sessions, based on the principles of motivational interviewing (MI), with a physiotherapist. The participants’ steps per day and other proxies of PA were measured using an accelerometer (SenseWear Pro®) at baseline, at the end of the PR program, and three months later. The group-by-time interaction effect was analyzed. Results: Of the 43 participants,17 were allocated to the intervention group and 26 to the usual-care control group (mean age 67.9 ± 7.9; 21 (49%) males; mean FEV1 predicted 47.1 ± 18.6). No difference between groups was found for any measure of PA at any point in time. Conclusions: In this study, counselling, based on MI, when embedded in a comprehensive PR program for people with COPD, showed no short-term or long-term effects on PA behavior. To investigate this potentially effective counselling intervention and to analyze the best method, timing and tailoring of an intervention embedded in a comprehensive outpatient PR program, further adequately powered research is needed.

Effectiveness of a Long-term Home-Based Exercise Training Program in Patients With COPD After Pulmonary Rehabilitation: A Multicenter Randomized Controlled Trial

Background: Most patients with COPD do not maintain exercise training after pulmonary rehabilitation (PR). Research question: Does a 12-month home-based, minimal-equipment strength training program after PR have an effect on dyspnea, exercise capacity, and patient-reported outcomes in patients with COPD? Study design and methods: In a parallel-arm multicenter study across four Swiss PR clinics, patients with COPD were allocated randomly (1:1 ratio) into an intervention group (IG; home-based strength training program) or control group (CG; usual care). The primary outcome was change in Chronic Respiratory Questionnaire (CRQ) dyspnea scale score from baseline to 12 months. Secondary outcomes were change in exercise capacity (1-min sit-to-stand-test [1MSTST], 6-min walk test [6MWT]), health-related quality of life, exacerbations, and symptoms. We assessed the IG's experience by interviews at study end. Main analyses were based on the intention-to-treat approach, and adjusted linear regression models were used. Results: One hundred twenty-three patients with COPD (IG, n = 61; CG, n = 62) were randomized, 61 of whom were women and whose mean ± SD age was 66.8 ± 8.1 years and mean ± SD FEV1 was 39.3 ± 15.3% predicted. One hundred four participants completed 12 months of follow-up (IG, n= 53; CG, n= 51). Of the 53 IG participants, 37 participants (70%) conducted the training until study end. We found no difference in change in CRQ dyspnea scale score over 12 months (adjusted mean difference, 0.28; 95% CI, -0.23 to 0.80; P = .27). We found moderate evidence for a difference in 1MSTST repetitions favoring the IG (adjusted mean difference, 2.6; 95% CI, 0.22-5.03; P = .033), but no evidence for an effect in other outcomes. Seventy-nine percent of the IG reported positive effects that they attributed to the training. Interpretation: The home exercise program had no effect on dyspnea, but improved 1MSTST performance and patient-perceived fitness. The supported program was well accepted by patients with COPD and may facilitate continued exercise training at home. Trial registry: ClinicalTrials.gov; No.: NCT03461887; URL: www.

Long-term experience with oral or inhaled vasodilator combination therapy in patients with pulmonary hypertension

BACKGROUND: Disease progression in pulmonary hypertension (PH) is common despite standard vasodilator monotherapy with iloprost, bosentan or sildenafil. OBJECTIVE: To investigate if the combination of these non-invasively applicable treatments is an effective option to address the multiple pathophysiological mechanisms present in PH. METHODS: We analysed the clinical course of 23 patients with PH, diagnosed as idiopathic (n = 15), chronic thromboembolic (n = 4), and associated with collagen vascular disease (n = 4), receiving combination vasodilator therapy at our institution. RESULTS: Vasodilator therapy before combination therapy consisted of inhaled iloprost (I; n = 12), or oral bosentan (B; n = 6) at a mean duration of 19 +/- 3 months. The combination therapy added was B (n = 8), sildenafil (S; n = 6) or I (n = 4) and in five patients, combination therapy was given from the beginning (3x BS, 1x IS, 1x IBS). Under combination therapy, the 6-minute walk distance (6MWD) increased significantly by 46.7 +/- 24.8 m (p = 0.02) after three months, and after six months it was still 38.3 +/- 28.3 m (p = 0.17) longer than before combination therapy. Respective changes in the Borg Scale and the NYHA functional class were -1.05 +/- 0.49 (p = 0.014) and -0.42 +/- 0.19 (p = 0.02) after three months and -0.21 +/- 0.65 (p = 0.61) and -0.38 +/- 0.29 (p = 0.26) after six months. Only minor side effects were reported. CONCLUSION: Combination vasodilator therapy in severe PH is safe and well tolerated. It significantly improves exercise capacity and stabilises the functional class in patients with severe PH deteriorating under single-agent therapy

Acute exacerbated COPD: room for improvement in key elements of care

INTRODUCTION: Hospitalizations because of acute exacerbated COPD (AECOPD) are a major burden to patients and the health care system. Interventions during acute and post-acute hospital care exist not only to improve short-term outcomes but also to prevent future exacerbations and disease progression. We aimed at measuring the implementation rates of acute and post-acute hospital care interventions for AECOPD. METHODS: We performed 24 months (January 1, 2012, to December 31, 2013) retrospective medical chart review of consecutive cases hospitalized to one of three public hospitals in the canton of Zurich due to AECOPD. Implementation rates of five acute care and seven post-acute care interventions were assessed. RESULTS: Data from 263 hospitalizations (61% male, mean age 68.5 years, 47% active smokers) were analyzed. The median length of stay was 9 days (interquartile range [IQR] 6-12 days). In all, 32% of hospitalizations were caused by individuals with previous hospitalizations because of AECOPD. Implementation rates of four acute care interventions were >75% (lowest was appropriate antibiotic therapy with 56%). Compared to this, implementation rates of five post-acute care interventions were <25% (lowest was patient education and self-management advice with 2%). CONCLUSION: The results of this audit revealed room for improvement mainly in post-acute care interventions for AECOPD.

One year follow-up of physical performance and quality of life in patients surviving COVID-19:a prospective cohort study

INTRODUCTION: The coronavirus disease (COVID-19) continues to affect many countries globally, with the long-term impact of the disease now being recognized. According to the latest research, some of the affected individuals continue to experience functional limitations, reduced physical performance and impaired health-related quality of life (HRQoL) even after eight months. This prospective cohort study aimed to describe the longer-term recovery of physical performance and HRQoL in COVID-19 survivors over one year. METHOD: A cohort (n = 43; 32-84 years old) hospitalized with COVID-19 between March and June 2020 was followed over one year and assessed at three time points: hospital discharge, 3 months and 12 months post-admission. Participants experienced mild (10/43) to critical (6/43) pneumonia and stayed in the hospital for a median of 10 days (IQR 9). Participants were assessed for physical performance (six-minute walk test), HRQoL (EQ-5D-5L), COVID-19 related limitations in functionality (PCFS), hospital-related anxiety and depression (HADS-A/-D), lung function (FEV1, FVC) and dyspnea during activity (mMRC). All assessments were conducted by physiotherapists trained in cardio-respiratory rehabilitation. RESULTS: After discharge, 8/34 showed reduced physical performance, 9/42 had lower HRQoL and 14/32 had COVID-19 induced limitations in functionality on the PCFS scale. Physical performance did not change significantly between discharge and 12-month follow-up, but 15/34 participants showed clinically relevant improvements in walking distance (>30 m). However, 16/34 had a decreased walking distance >30 m when comparing 3-month to 12-month follow-up. At 12 months, 12/41 of participants still perceived COVID-19 related limitations in daily life on the PCFS scale. For HRQoL, 12/41 participants still perceived moderate-to-severe symptoms of pain and discomfort and 13/41 slight-to-severe symptoms of anxiety and depression. CONCLUSION: This cohort of adult patients hospitalized for mild to severe COVID-19 in Switzerland was generally mildly affected but still reported some limitations after one year. These results offer preliminary indications for ongoing support after hospitalization and point towards the need for specific, individualized follow-up to support their recovery
