Patient adherence is a critical factor for success of patient-administered therapies, including incentive spirometry (IS). Patient adherence with IS is not known, so we sought to evaluate providers' perspectives on the current state of IS adherence and elucidate possible factors hindering patient adherence. ⋯ These findings from a large national survey of health care providers highlight the need for improved IS adherence and indicate that patient forgetfulness may be a large contributor to nonadherence. Efforts aimed at improving IS adherence are warranted.

The 6-min walk test (6MWT) is commonly performed to assess functional status in patients with chronic thromboembolic pulmonary hypertension. However, changes in heart rate and oxygen saturation (SpO2 ) patterns during 6MWT in patients with chronic thromboembolic pulmonary hypertension remain unclear. ⋯ Heart rate and SpO2 change patterns during 6MWT are predominantly associated with pulmonary hemodynamics in subjects with chronic thromboembolic pulmonary hypertension. Evaluating heart rate and SpO2 change patterns during 6MWT may serve as a safe and convenient way to follow the change in pulmonary hemodynamics.

Prophylactic Antibiotic Use in COPD and the Potential Anti-Inflammatory Activities of Antibiotics.
Antibiotics have previously demonstrated anti-inflammatory properties, and they have been linked to therapeutic benefit in several pulmonary conditions that feature inflammation. Previous research suggests that these anti-inflammatory properties may be beneficial in the treatment of COPD. This review assesses the potential benefit of prophylactic, long-term, and low-dose antibiotic therapy in COPD, and whether any effects seen are anti-inflammatory in nature. ⋯ The macrolide class of antibiotics exhibited convincing anti-inflammatory properties with relevance to COPD, implicating several pathways as potential mechanisms of action. In conclusion, the therapeutic benefit of macrolide antibiotics in subjects with stable COPD is consistent with anti-inflammatory properties, and macrolides should be considered as a potential therapy in COPD. Safety concerns regarding antibiotic resistance need to be addressed before widespread use in clinical practice.

COPD is an underdiagnosed, undertreated, and yet largely preventable disease. COPD affects millions of Americans on a daily basis, accounts for tens of thousands of deaths per year, and costs billions to the United States health-care system annually. Further, it impacts the quality of life for patients living with the disease. ⋯ Numerous strategies have been proposed to combat these high rates, including the use of discharge bundles, hospital at-home programs, telemedicine, and tele-rehabilitation, but no single best strategy has emerged. The COPD National Action Plan was introduced in 2017 as part of a multi-stakeholder endeavor to encourage collaboration among various patients, caregivers, physicians, researchers, and policymakers to optimize awareness, diagnosis, and treatment of this disease. It is time to make COPD care a public health priority.
