Early mobilization of patients in the intensive care unit (ICU) is safe, feasible, and beneficial. However, implementation of early mobility as part of routine clinical care can be challenging. The objective of this review is to identify barriers to early mobilization and discuss strategies to overcome such barriers. ⋯ These barriers varied across ICUs and within disciplines, depending on the ICU patient population, setting, attitude, and ICU culture. To overcome the identified barriers, over 70 strategies were reported and are synthesized in this review, including: implementation of safety guidelines; use of mobility protocols; interprofessional training, education, and rounds; and involvement of physician champions. Systematic efforts to change ICU culture to prioritize early mobilization using an interprofessional approach and multiple targeted strategies are important components of successfully implementing early mobility in clinical practice.

Randomized Controlled Trial Multicenter Study
Palliative Care for Patients Dying in the Intensive Care Unit with Chronic Lung Disease Compared with Metastatic Cancer.
Palliative care has been focused largely on patients with cancer, and yet patients with chronic lung diseases also have high morbidity and mortality. The majority of deaths in intensive care units (ICUs) follow decisions to withhold or withdraw life-sustaining treatments, suggesting that palliative care is critically important in this setting. ⋯ Among patients who die in the ICU, patients with ILD and COPD receive fewer elements of palliative care and have longer lengths of stay than patients with cancer. These findings identify areas for improvement in caring for patients with chronic lung diseases. Clinical trial registered with www.clinicaltrials.gov (NCT00685893).

Physical inactivity is associated with poor outcomes among patients with chronic obstructive pulmonary disease (COPD). ⋯ During this 18-month trial among outpatients with COPD, a health coach-based behavioral intervention did not improve scores in the dyspnea domain of the Chronic Respiratory Questionnaire or 6-minute-walk test distance. However, subgroup analyses suggested that there may be differential effects for specific outcomes that vary with severity of COPD. Specifically, benefits of this low-intensity intervention may be limited to 6-minute walk distance among patients with moderate spirometric impairment. Clinical trial registered with www.clinicaltrials.gov (NCT1108991).

To understand how well palliative care is provided in the intensive care unit (ICU) and to direct improvements, measurement of the quality of care delivered is requisite. ⋯ Delivering high-quality palliative care in the ICU requires assessing key patient-centered domains. However, assessments from different perspectives do not always agree with technical quality of care as measured through chart-based metrics. We found deficits across seven domains of technical quality that were not correlated with either nurse or family ratings. Despite care gaps, families were generally satisfied with the care delivered. We conclude that each measurement perspective provides an independent view that can guide quality improvement and innovation work as well as subsequent research.

Abnormalities in mucus production and qualitative properties such as mucus hydration are central to the pathophysiology of airway disease including cystic fibrosis, asthma, and chronic bronchitis. In vitro air-liquid interface epithelial cell cultures demonstrate direct relationships between mucociliary transport, periciliary liquid (PCL) height, and mucus concentration (expressed as percent solids or partial osmotic pressure). In health, the osmotic modulus/pressure of the PCL exceeds that of the mucus layer, resulting in efficient, low-friction movement of mucus. ⋯ Collectively, these data suggest the importance of mucus concentration in the pathogenesis of airway disease. It is important to understand the precise mechanisms that result in mucus hyperconcentration, for example, mucin overproduction versus abnormal regulation of ion/water transport, which may be unique to and characteristic of each disease phenotype. The measurement of mucus concentration may be a simple method to diagnose chronic bronchitis, monitor its progression, and serve as a biomarker for development of new therapies.
