INTRODUCTION This study investigated the survival rates of occupants of passenger cars involved in a fatal crash between 2000 and 2003. METHODS The information from every fatal crash in the United States between 2000 and 2003 was analyzed. Variables such as seat position, point of impact, rollover, restraint use, vehicle type, vehicle weight, occupant(More)
BACKGROUND β-Blocker therapy has been shown to improve survival among patients with ischaemic heart disease (IHD) and congestive heart failure (CHF) and is underused among patients with chronic obstructive pulmonary disease (COPD). Evidence regarding the optimal use of β-blocker therapy during an acute exacerbation of COPD is particularly weak. METHODS We(More)
BACKGROUND Mortality prediction models generally require clinical data or are derived from information coded at discharge, limiting adjustment for presenting severity of illness in observational studies using administrative data. OBJECTIVES To develop and validate a mortality prediction model using administrative data available in the first 2 hospital(More)
BACKGROUND Lowering hospital readmission rates has become a primary target for the Centers for Medicare & Medicaid Services, but studies of the relationship between adherence to the recommended hospital care processes and readmission rates have provided inconsistent and inconclusive results. OBJECTIVE To examine the association between hospital(More)
OBJECTIVES Guidelines for treatment of healthcare-associated pneumonia (HCAP) recommend empirical therapy with broad-spectrum antimicrobials. Our objective was to examine the association between guideline-based therapy (GBT) and outcomes for patients with HCAP. PATIENTS AND METHODS We conducted a pharmacoepidemiological cohort study at 346 US hospitals.(More)
BACKGROUND OSA is associated with increased risks of respiratory complications following surgery. However, its relationship to the outcomes of hospitalized medical patients is unknown. METHODS We carried out a retrospective cohort study of patients with pneumonia at 347 US hospitals. We compared the characteristics, treatment, and risk of complications(More)
BACKGROUND Most U.S. hospitals publicly report 30-day risk-standardized mortality rates for pneumonia. Rates exclude severe cases, which may be assigned a secondary diagnosis of pneumonia and a principal diagnosis of sepsis or respiratory failure. By assigning sepsis and respiratory failure codes more liberally, hospitals might improve their reported(More)
BACKGROUND Quality care depends on effective communication between caregivers, but it is unknown whether time spent communicating is associated with communication outcomes. OBJECTIVE To assess the association between time spent communicating, agreement on plan of care, and patient satisfaction. DESIGN Time-motion study with cross-sectional survey. (More)
BACKGROUND Healthcare-associated pneumonia (HCAP) is an entity distinct from community-acquired pneumonia (CAP). HCAP has a higher case-fatality rate, due either to HCAP organisms or to the health status of HCAP patients. The contribution of HCAP criteria to case-fatality rate is unknown. METHODS We conducted a retrospective review of adult patients(More)
OBJECTIVE The focused assessment with sonography for trauma (FAST) exam is a routine diagnostic adjunct in the initial assessment of blunt trauma victims but lacks the ability to reliably predict which patients require laparotomy. Physiologic data play a major role in decision making regarding the need for emergent laparotomy versus further diagnostic(More)
