In COPD, hospital admissions and readmissions account for the majority of health-care costs. The aim of this prospective randomized controlled study was to determine if early pulmonary rehabilitation, commenced as an inpatient and continued after discharge, reduced acute health-care utilization.
                Consecutive COPD patients (n = 397), admitted with an exacerbation, were screened: 228 satisfied the eligibility criteria, of whom 97 consented to randomization to rehabilitation or usual care. Both intention-to-treat and per-protocol analyses are reported with adherence being defined a priori as participation in at least 75% of rehabilitation sessions.
                The participants were elderly with severe impairment of pulmonary function, poor health-related quality of life and high COPD-related morbidity. The rehabilitation group demonstrated a 23% (95% CI: 11-36%) risk of readmission at 3 months, with attendees having a 16% (95% CI: 0-32%) risk compared with 32% (95% CI: 19-45%) for usual care. These differences were not significant. There were a total of 79 COPD-related readmission days (1.7 per patient, 95% CI: 0.6-2.7, P = 0.19) in the rehabilitation group, compared with 25 (1.3 per patient, 95% CI: 0-3.1, P = 0.17) for the attendees and 209 (4.2 per patient, 95% CI: 1.7-6.7) for usual care. The BMI, airflow obstruction, dyspnoea and exercise capacity index showed a non-significant trend to greater improvement among attendees compared with those receiving usual care (5.5 (2.3) and 5.6 (2.7) at baseline, improving to 3.7 (1.9) and 4.5 (2.5), respectively, at 3 months). No adverse effects were identified.
                Early inpatient-outpatient rehabilitation for COPD patients admitted with an exacerbation was feasible and safe, and was associated with a non-significant trend towards reduced acute health-care utilization. We have developed a rehabilitation programme at home and have investigated its effects on quality of life (QOL), lung function, and exercise tolerance in patients with chronic obstructive pulmonary disease (COPD). We studied 43 patients with severe airflow obstruction: forced expiratory volume in one second (FEV1) 1.3 +/- 0.4 l (mean +/- SD), FEV1/inspiratory vital capacity (IVC) 37 +/- 7.9%. After stratification, 28 patients were randomly allocated in a home rehabilitation programme for 12 weeks. Fifteen patients in a control group received no rehabilitation. The rehabilitation group received physiotherapy by the local physiotherapist, and supervision by a nurse and a general practitioner. Quality of life was assessed by the four dimensions of the Chronic Respiratory Questionnaire (CRQ). We found a highly significant improvement in the rehabilitation group compared to the control group for the dimensions dyspnoea, emotion, and mastery. Lung function showed no changes in the rehabilitation group. The exercise tolerance improved significantly in the rehabilitation group compared to the control group. The improvement in quality of life was not correlated with the improvement in exercise tolerance. Rehabilitation of COPD patients at home may improve quality of life; this improvement is not correlated with an improvement in lung function and exercise tolerance. Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality in India. Drug treatment alone does not optimize therapy. Pulmonary rehabilitation has been found to improve the physical efficiency of COPD patients. Therefore, we evaluated the effect of domiciliary pulmonary rehabilitation programme in patients of COPD.
                Forty patients of stable COPD having severe airflow obstruction were included in the study. They were divided into control and experimental groups randomly. Rehabilitation included walking, breathing exercises, postural drainage, controlled coughing and changes in life style activities. Exercises of 30 minutes duration were performed at home twice daily for four weeks supervision. Six-minute walking distance, forced expiratory volume in one seocond (FEV1) and various indices of chronic respiratory disease questionnaire (CRDQ) were measured in both experimental and control groups before and after completion of the study.
                In the experimental group, after four weeks, the mean (+/- SD) difference in six-minute walking distance, dyspnoea, mastery, fatigue and emotion scores were 54.2 (26.7) meters, 0.96 (0.26), 0.89 (0.44), 0.90 (0.40) and 0.91 (0.32) respectively. Changes in all these parameters were statistically significant (p < 0.001) as compared to the control group. There was no significant change in FEV1.
                It was concluded that domiciliary pulmonary rehabilitation for four weeks results in significant improvement in the quality of life and exercise tolerance, even without improvement in FEV1. BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are characterised by increased dyspnoea, reduced quality of life and muscle weakness. Re-exacerbation and hospital admission are common. Pulmonary rehabilitation (PR) administered after hospital admission for an exacerbation can improve quality of life and exercise capacity. OBJECTIVE To determine whether outpatient post-exacerbation PR (PEPR) could reduce subsequent hospital admission episodes. METHODS Patients admitted to hospital for an exacerbation of COPD were randomised to receive either usual follow-up care (UC) or PEPR after discharge. Hospital admission and emergency department attendances for COPD exacerbations were recorded over a 3-month period and analysed on an intention-to-treat basis. Secondary outcomes included exercise capacity and quadriceps strength. RESULTS 60 patients underwent concealed randomisation at the time of their hospital discharge (UC: n=30, mean (SD) age 65 (10) years, forced expiratory volume in 1 s (FEV(1)) 52 (22)% predicted; PEPR: n=30, 67(10) years, 52 (20)% predicted). The proportion of patients re-admitted to hospital with an exacerbation was 33% in the UC group compared with 7% in those receiving PEPR (OR 0.15, 95% CI 0.03 to 0.72, p=0.02). The proportion of patients that experienced an exacerbation resulting in an unplanned hospital attendance (either admission or review and discharge from the emergency department) was 57% in the UC group and 27% in those receiving PEPR (OR 0.28, 95% CI 0.10 to 0.82, p=0.02). CONCLUSIONS Post-exacerbation rehabilitation in COPD can reduce re-exacerbation events that require admission or hospital attendance over a 3-month period. Clinical Trials Registration Number NCT00557115. To examine the short- and long-term effects of an outpatient pulmonary rehabilitation program for COPD patients on dyspnea, exercise, health-related quality of life, and hospitalization rate.
                Secondary-care respiratory clinic in Barcelona.
                We conducted a randomized controlled trial with blinding of outcome assessment and follow-up at 3, 6, 9, 12, 18, and 24 months. Sixty patients with moderate to severe COPD (age 65 +/- 7 years; FEV(1) 35 +/- 14%) were recruited. Thirty patients randomized to rehabilitation received 3 months of outpatient breathing retraining and chest physiotherapy, 3 months of daily supervised exercise, and 6 months of weekly supervised breathing exercises. Thirty patients randomized to the control group received standard care.
                We found significant differences between groups in perception of dyspnea (p < 0.0001), in 6-min walking test distance (p < 0.0001), and in day-to-day dyspnea, fatigue, and emotional function measured by the Chronic Respiratory Questionnaire (p < 0. 01). The improvements were evident at the third month and continued with somewhat diminished magnitude in the second year of follow-up. The PR group experienced a significant (p < 0.0001) reduction in exacerbations, but not the number of hospitalizations. The number of patients needed to treat to achieve significant benefit in health-related quality of life for a 2-year period was approximately three.
                Outpatient rehabilitation programs can achieve worthwhile benefits that persist for a period of 2 years. Patients with chronic pulmonary disease have been shown to benefit from pulmonary rehabilitation programs. Published work has often been from specialized teaching centers and has involved inpatient stay. We assessed an entirely outpatient-based program of pulmonary rehabilitation in patients with chronic lung disease, using the St. George's Respiratory Questionnaire (SGRQ) (which measures health-related quality of life) as the primary outcome measure.
                We undertook a randomized, prospective, parallel-group controlled study of an outpatient rehabilitation program in 65 patients with COPD (44 men and 21 women; mean age, 69.5 years [SD, 9.2 years]; FEV(1), 41% predicted [SD, 18.5%]). The active group (n = 36) took part in a 6-week program of education (2 h weekly) and exercise (1 h weekly). The control group (n = 29) were reviewed routinely as medical outpatients. The SGRQ was administered under supervision by a blinded observer at study entry, 12 weeks, and 24 weeks.
                The SGRQ in the active group was 59.9 (SE, 2.0) at study entry (n = 36), 47.4 (SE, 2.3) at 12 weeks (n = 32), and 50.6 (SE, 2.5) at 24 weeks (n = 24). The SGRQ in the control group was 59.3 (SE, 2.5) at study entry and did not change significantly over 24 weeks. There was a difference of 10.4 points (confidence interval [CI], 3.6 to 17.3) between the two groups at 12 weeks (p < 0.001) and of 8.1 points (CI, 1.4 to 14.9) at 24 weeks (p = 0.02) in favor of the active group.
                A 6-week outpatient-based program significantly improved quality of life in patients with moderate-to-severe COPD. Benefit was still evident after 24 weeks. Several studies of chronic obstructive pulmonary disease (COPD) have shown that pulmonary rehabilitation, consisting of at least three training sessions a week, improves exercise performance and health status. This study investigates feasibility, effect and economic aspects of a rehabilitation programme consisting of two sessions a week for 8 weeks. Twenty-four patients with moderate COPD were randomized to rehabilitation and 21 to placebo. Patients were assigned to an 8-week programme of exercise plus education (Exercise group) or conventional community care (Placebo group). The rehabilitation program was carried out in a hospital outpatient setting and consisted of 16 h exercise and 13.5 h of education. The exercise group received physiotherapy and education twice a week. Seven patients did not complete the programme. The characteristics of the 38 COPD-patients at baseline were the following: (mean +/- SD) forced expiratory volume in 1 sec (FEV1) 1.1+/-0.4 1 (47% of predicted), 6-min walking distance (6MWD) 413+/-75 m, score of St. George's Respiratory Questionnaire (SGRQ) 44+/-21. Health-status, assessed by SGRQ and The Psychological General Well-being (PGWB) Index, did not improve. Rehabilitation resulted in an insignificant improvement in the 6MWD [29 m (95% confidence interval: -8 -66 m)]. We conclude that a rehabilitation program consisting of exercise and education twice a week for 8 weeks had no effect on exercise performance and well being in patients with moderate COPD. Home-based rehabilitation is a promising approach to improve access to pulmonary rehabilitation.
                To assess whether self-monitored, home-based rehabilitation is as effective as outpatient, hospital-based rehabilitation in patients with chronic obstructive pulmonary disease (COPD).
                Randomized, multicenter, noninferiority trial.
                10 academic and community medical centers in Canada.
                252 patients with moderate to severe COPD.
                After a 4-week education program, patients took part in home-based rehabilitation or outpatient, hospital-based rehabilitation for 8 weeks. They were followed for 40 weeks to complete the 1-year study.
                The primary outcome was the change in Chronic Respiratory Questionnaire dyspnea subscale score at 1 year. The primary analysis took a modified intention-to-treat approach by using all patients who provided data at the specified follow-up time, regardless of their level of adherence. The analysis used regression modeling that adjusted for the effects of center, sex, and baseline level. All differences were computed as home intervention minus outpatient intervention.
                Both interventions produced similar improvements in the Chronic Respiratory Questionnaire dyspnea subscale at 1 year: improvement in dyspnea of 0.62 (95% CI, 0.43 to 0.80) units in the home intervention (n = 107) and 0.46 (CI, 0.28 to 0.64) units in the outpatient intervention (n = 109). The difference between the 2 treatments at 1 year was small and clinically unimportant. The 95% CI of the difference did not exceed the prespecified noninferiority margin of 0.5: difference in dyspnea score of 0.16 (CI, -0.08 to 0.40). Most adverse events were related to COPD exacerbations. No serious adverse event was considered to be related to the study intervention.
                The contribution of the educational program to the improvement in health status and exercise tolerance cannot be ascertained.
                Home rehabilitation is a useful, equivalent alternative to outpatient rehabilitation in patients with COPD.
Evidence from nine small studies of moderate methodological quality, suggests that pulmonary rehabilitation is a highly effective and safe intervention to reduce hospital admissions and mortality and to improve health-related quality of life in COPD patients who have recently suffered an exacerbation of COPD.
