Acoustic properties of speech have previously been identified as possible cues to depression, and there is evidence that certain vocal parameters may be used further to objectively discriminate between depressed and suicidal speech. Studies were performed to analyze and compare the speech acoustics of separate male and female samples comprised of normal(More)
BACKGROUND Both the Institute of Medicine and the Agency for Healthcare Research and Quality suggest patient safety can be enhanced by implementing aviation Crew Resource Management (CRM) in health care. CRM emphasizes six key areas: managing fatigue, creating and managing teams, recognizing adverse situations (red flags), cross-checking and communication,(More)
OBJECTIVE The aim of the present study was to determine if acoustic measures of voice, characterizing specific spectral and timing properties, predict clinical ratings of depression severity measured in a sample of patients using the Hamilton Depression Rating Scale (HAMD) and Beck Depression Inventory (BDI-II). STUDY DESIGN This is a prospective study.(More)
BACKGROUND Failures of communication are a major contributor to perioperative adverse events. Transitions of care may be particularly vulnerable. We sought to improve postoperative handovers. METHODS We introduced a multimodal intervention in an adult and a pediatric postanesthesia care unit (PACU) to improve postoperative handovers between anesthesia(More)
BACKGROUND Acknowledging the need to improve team communication and coordination among health care providers, health care administrators and improvement officers have been quick to endorse and invest in aviation crew resource management (CRM). Despite the increased interest in CRM there exists limited data on the effectiveness of CRM to change team behavior(More)
OBJECTIVE The primary objective of this study was to create a methodology for measuring transient levels of physician workload in a live emergency department (ED) environment. BACKGROUND Characterizing, defining, and measuring aspects of this interrupt-driven work environment represent the preliminary steps in addressing impending issues concerning ED(More)
BACKGROUND As the demands on the emergency medicine (EM) system continue to increase, improvements in the organization of work and the access to timely clinical and system information will be required for providers to manage their workload in a safe and efficient manner. Information technology (IT) solutions are beginning to find their place in the(More)
OBJECTIVE To determine if using dense data capture to measure heart rate volatility (standard deviation) measured in 5-minute intervals predicts death. BACKGROUND Fundamental approaches to assessing vital signs in the critically ill have changed little since the early 1900s. Our prior work in this area has demonstrated the utility of densely sampled data(More)
BACKGROUND Patient complaints are associated with increased malpractice risk but it is unclear if complaints might be associated with medical complications. The purpose of this study was to determine whether an association exists between patient complaints and surgical complications. METHODS A retrospective analysis of 16,713 surgical admissions was(More)
STUDY OBJECTIVE The objective of this investigation is to determine time-dependent workload patterns for emergency department (ED) physician teams across work shifts. A secondary aim was to demonstrate how ED demand patterns and the timing of shift changes influence the balance of workload among a physician team. METHODS Operational measurements of an(More)
