Patients with sleep disorders are most concerned with the impact of these diseases on their quality of life. Patient-reported outcome (PRO) measurement tools, which assess aspects of a patient's health status that come directly from the patient, are well suited to evaluate quality of life related to sleep disorders. ⋯ This article reviews various PRO measure tools used for sleep disorders in clinical and research settings. These instruments may play a role in screening, diagnosis, and monitoring of various sleep disorders.

Review Case Reports
Evaluation and management of pill aspiration: case discussion and review of the literature.
Pill aspiration represents a unique type of foreign body aspiration requiring a distinct diagnostic and therapeutic approach. In many cases, the "foreign body" itself may no longer be present, whereas the airway manifestations may persist for months to years. ⋯ Endobronchial surveillance may be important to identify impending airway obstruction via secretions, edema, granulation tissue, or fibrotic stricture. In many cases, the airway sequelae of pill aspiration can be effectively managed with bronchoscopy.

Multicenter Study
Flash mob research: a single-day, multicenter, resident-directed study of respiratory rate.
Vital signs are critical data in the care of hospitalized patients, but the accuracy with which respiratory rates are recorded in this population remains uncertain. We used a novel flash mob research approach to evaluate the accuracy of recorded respiratory rates in inpatients. ⋯ Among hospitalized patients across the United States, recorded respiratory rates are higher than directly observed measurements and are significantly more likely to be 18 or 20 breaths/min.

Multicenter Study
Characterizing functional lung heterogeneity in COPD using reference equations for CT scan-measured lobar volumes.
CT scanning is increasingly used to characterize COPD. Although it is possible to obtain CT scan-measured lung lobe volumes, normal ranges remain unknown. Using COPDGene data, we developed reference equations for lobar volumes at maximal inflation (total lung capacity [TLC]) and relaxed exhalation (approximating functional residual capacity [FRC]). ⋯ Reference equations for lobar volumes may be useful in assessing regional lung dysfunction and how it changes in response to pharmacologic therapies and surgical or endoscopic lung volume reduction.

Randomized Controlled Trial
The Epworth Sleepiness Scale: conventional self vs physician administration.
The Epworth Sleepiness Scale (ESS) is a simple, self-administered questionnaire that provides a measurement of the subject's level of daytime sleepiness, and is widely used for patients with obstructive sleep apnea (OSA). Some works undermined its accuracy. The aim of this study was to compare self-administered ESS scores to physician-administered scores in a sample of patients with suspicion of OSA. ⋯ Our results lead us to consider the physician-administered ESS to be more accurate than the traditional ESS; thus, our suggestion is to validate this new method of administration.
