IMPORTANCE Little is known about functional trajectories of older persons in the year before and after admission to the intensive care unit (ICU) or how pre-ICU functional trajectories affect post-ICU functional trajectories and death. OBJECTIVES To characterize functional trajectories in the year before and after ICU admission and to evaluate the(More)
PURPOSE Although bronchoscopy has conventionally been performed using conscious sedation, advanced diagnostic techniques like endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), peripheral EBUS, and electromagnetic navigational bronchoscopy add to procedural complexity. The adaptation of these techniques by bronchoscopists of(More)
INTRODUCTION Delirium is a serious and prevalent problem in intensive care units (ICU). The purpose of this study was to develop a research algorithm to enhance detection of delirium in critically ill ICU patients using chart review to complement a validated clinical delirium instrument. METHODS Prospective cohort study of 178 patients 60 years and older(More)
BACKGROUND Accurate measurement of quality of life in older ICU survivors is difficult but critical for understanding the long-term impact of our treatments. Activities of daily living (ADLs) are important components of functional status and more easily measured than quality of life (QOL). We sought to determine the cross-sectional associations between(More)
In this article, the authors demonstrate a time-series analysis based on a hierarchical Bayesian model of a Poisson outcome with an excessive number of zeroes. The motivating example for this analysis comes from the intensive care unit (ICU) of an urban university teaching hospital (New Haven, Connecticut, 2002-2004). Studies of medication use among older(More)
BACKGROUND Each year in the United States an estimated 1.5 million people develop pleural effusions and approximately 178,000 thoracenteses (12%) are performed. While it has been established that malignant effusions are associated with increased mortality, the association between mortality and all-cause pleural effusions in a medical population has not been(More)
Of the 1.5 million people diagnosed with pleural effusion in the USA annually, ~178 000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied.This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was(More)
OBJECTIVES To evaluate the feasibility of using unattended, portable polysomnography (PSG) to measure sleep among patients in the medical intensive care unit (MICU). BACKGROUND Accurate measurement of sleep is critical to studies of MICU sleep deprivation. Although PSG is the gold standard, there is limited data regarding the feasibility of utilizing(More)
Background.  Sepsis is a major cause of morbidity and mortality among older adults. The main goals of this study were to assess the association of sepsis at intensive care unit (ICU) admission with mortality and to identify predictors associated with increased mortality in older adults. Methods.  We conducted a prospective cohort study of 309 participants(More)
BACKGROUND Pleural effusions impact over 1.5 million people annually in the United States and cause significant morbidity. Although therapeutic thoracentesis is associated with improvement in respiratory parameters, unanswered questions remain regarding its impact. OBJECTIVE The purpose of this study was to investigate patient-centered outcomes, the need(More)
