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)
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)
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)

Many hospitals wish to improve their patients' experience of care. To learn whether social media could be used as a tool to engage patients and to identify opportunities for hospital quality improvement (QI), we solicited patients' narrative feedback on the Baystate Medical Center Facebook page during a 3-week period in 2014. Two investigators used directed(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)
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 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)
