ABSTRACT Pulmonary rehabilitation (PR) is an effective therapeutic strategy to improve health outcomes in patients with chronic obstructive pulmonary disease (COPD); however, there is insufficient PR capacity to service all COPD patients, thus necessitating creative solutions to increase the availability of PR.
To examine the efficacy of PR delivered via Telehealth (Telehealth-PR) compared with PR delivered in person through a standard outpatient hospital-based program (Standard-PR).
One hundred forty-seven COPD patients participated in an eight-week rural PR program delivered via Telehealth-PR. Data were compared with a parallel group of 262 COPD patients who attended Standard-PR. Education sessions were administered two days per week via Telehealth, and patients exercised at their satellite centre under direct supervision. Standard-PR patients viewed the same education sessions in person and exercised at the main PR site. The primary outcome measure was change in quality of life as evaluated by the St George's Respiratory Questionnaire (SGRQ). A noninferiority analysis was performed using both intention-to-treat and per-protocol approaches.
Both Telehealth-PR and Standard-PR resulted in clinically and statistically significant improvements in SGRQ scores (4.5 ± 0.8% versus 4.1 ± 0.6%; P<0.05 versus baseline for both groups), and the improvement in SGRQ was not different between the two programs. Similarly, exercise capacity, as assessed by 12 min walk test, improved equally in both Telehealth-PR and Standard-PR programs (81±10 m versus 82 ± 10 m; P<0.05 versus baseline for both groups).
Telehealth-PR was an effective tool for increasing COPD PR services, and demonstrated improvements in quality of life and exercise capacity comparable with Standard-PR.

    ABSTRACT: Pulmonary rehabilitation programs vary in terms of duration and location. Differences also exists in the patients who are judged eligible for rehabilitation. This article reviews the options clinicians have to organize programs in terms of who should be referred, when, where, and for how long. There are several risk factors for lack of uptake and non-adherence to programs. Logistical aspects are also an important barrier. In terms of election, patients with muscle dysfunction are likely the best candidates for exercise training. Patients with exercise-induced symptoms and those after exacerbations should also be referred.

    ABSTRACT: Respiratory therapy (RT) has been shown to improve dyspnea, exercise capacity and health-related quality of life in patients with COPD. RT has also shown benefits in diseases other than COPD but the degree of evidence is lower. The fundamental components of RT programs are muscle training, education and chest physiotherapy. Occupational therapy, psychosocial support and nutritional intervention should also be considered. Home programs have been shown to be as effective as hospital therapy. The duration of rehabilitation programs should not be less than 8 weeks or 20 sessions. Early initiation of RT, even during exacerbations, has proven safe and effective. The use of oxygen or noninvasive ventilation during training is controversial and dependent on the patient's situation. At present, the best strategy for maintaining the benefits of RT in the long term is unknown. Longer RT programs or telemedicine could play a key role in extending the results obtained.

    ABSTRACT: Variable aspects of pulmonary rehabilitation (PR) programs include staff composition, setting, structure, and duration. Longer PR programs generally translate into greater improvements in outcomes and (perhaps) prolonged maintenance of benefits. Barriers to PR include transportation issues, inconvenience for the patient, cost and insurance coverage problems, lack of perceived benefit, concurrent illness, and influence of the provider. PR settings include inpatient and outpatient environments. PR has been shown to improve health care utilization during or immediately following chronic obstructive pulmonary disease exacerbations. Challenges to providing PR may be partially addressed by technological developments.
