Multicenter Study
Cohort study on the prevalence and risk factors for delayed pulmonary complications in adults following minor blunt thoracic trauma.
The objectives of this study are to determine the prevalence, risk factors, and time to onset of delayed hemothorax and pneumothorax in adults who experienced a minor blunt thoracic trauma. ⋯ The presence of at least one rib fracture between the third and ninth rib on the x-ray of the hemithorax is a significant risk factor for delayed hemothorax and pneumothorax.

Randomized Controlled Trial Multicenter Study
Predictors Of admission to hospital of patients triaged as nonurgent using the Canadian Triage and Acuity Scale.
To identify factors known prior to triage that might have predicted hospital admission for patients triaged by the Canadian Triage Acuity Scale (CTAS) as level 5 (CTAS 5, nonurgent) and to determine whether inappropriate triage occurred in the admitted CTAS 5 patients. ⋯ Most of the CTAS 5 patients who were subsequently admitted to hospital may have qualified for a higher triage category. Two potential modifiers, age over 65 and arrival by ambulance, may have improved the prediction of admission in CTAS 5 patients. However, the consistent application of existing CTAS criteria may also be important to prevent incorrect triage.

Does the sedation regimen affect adverse events during procedural sedation and analgesia in injection drug users?
Injection drug users (IDUs) often undergo procedural sedation and analgesia (PSA) as part of emergency department (ED) treatment. We compared adverse events (AEs) using a variety of sedation regimens. ⋯ For IDU PSA, the overall AE rate was 6.5%, and propofol appeared to have a significantly lower rate.

Adverse events are rare among adults 50 years of age and younger with flank pain when abdominal computed tomography is not clinically indicated according to the emergency physician.
Many emergency physicians (EPs) order "confirmatory" abdominal computed tomography (CT) in young flank pain patients, despite a high clinical suspicion of renal colic and the risk of radiation exposure. We measured the adverse outcome rate among flank pain patients identified as not requiring abdominal CT by the EP on a data form, regardless of whether CT was eventually ordered. Our secondary objective was to describe diagnoses other than renal colic identified by CT in this population. ⋯ Adverse events were rare (< 1.5%) among patients < 50 years old with flank pain when CT was not required according to the clinical assessment of the EP. Future research should assess the adverse outcomes of withholding CT in low-risk patients using a larger patient sample.

How many patients who had a negative computed tomography and lumbar puncture result on initial evaluation were diagnosed with subarachnoid hemorrhage in the subsequent 6 months to 3 years? ⋯ To determine the sensitivity of both a negative computed tomography and a negative lumbar puncture in ruling out subarachnoid hemorrhage.
