Randomized Controlled Trial Multicenter Study Comparative Study
The effects of pulmonary rehabilitation in the national emphysema treatment trial.
Pulmonary rehabilitation is an established treatment in patients with chronic lung disease but is not widely utilized. Most trials have been conducted in single centers. The National Emphysema Treatment Trial (NETT) provided an opportunity to evaluate pulmonary rehabilitation in a large cohort of patients who were treated in centers throughout the United States. ⋯ The NETT experience demonstrates the effectiveness of pulmonary rehabilitation in patients with severe emphysema who were treated in a national cross-section of programs. Pulmonary rehabilitation plays an important role in preparing and selecting patients for surgical interventions such as LVRS.

Randomized Controlled Trial Multicenter Study
Noninvasive vs conventional mechanical ventilation in acute respiratory failure: a multicenter, randomized controlled trial.
Noninvasive mechanical ventilation (NIMV) is beneficial for patients with acute respiratory failure (ARF) when added to medical treatment. However, its role as an alternative to conventional mechanical ventilation (CMV) remains controversial. Our aim was to compare the efficacy and resource consumption of NIMV against CMV in patients with ARF. ⋯ NIMV reduces the need for intubation and therapeutic intervention in patients with ARF from different causes. There is a nonsignificant trend of reduction in ICUs and hospital mortality together with fewer complications during ICU stay.
