Comparative Study
Comparison of procedural sedation for the reduction of dislocated total hip arthroplasty.
Various types of sedation can be used for the reduction of a dislocated total hip arthroplasty. Traditionally, an opiate/benzodiazepine combination has been employed. The use of other pharmacologic agents, such as etomidate and propofol, have more recently gained popularity. Currently no studies directly comparing these sedation agents have been carried out. The purpose of this study is to compare differences in reduction and sedation outcomes, including recovery times, of these 3 sedation agents. ⋯ For reduction of dislocated total hip arthroplasty under procedural sedation, propofol appears to have fewer complications and a trend toward more rapid recovery than both etomidate and opiate/benzodiazepine. These data support the use of propofol as first line agent for procedural sedation of dislocated total hip arthroplasty, with fewer complications and a shorter recovery period.

Severe sepsis is a leading cause of non-coronary death in hospitals across the United States. Early identification and risk stratification in the emergency department (ED) is difficult because there is limited ability to predict escalation of care. In this study we evaluated if a sustained shock index (SI) elevation in the ED was a predictor of short-term cardiovascular collapse, defined as vasopressor dependence within 72 hours of initial presentation. ⋯ ED patients with severe sepsis and a sustained SI elevation appear to have higher rates of short-term vasopressor use, and a greater number of organ failures contrasted to patients without a sustained SI elevation. An elevated SI may be a useful modality to identify patients with severe sepsis at risk for disease escalation and cardiovascular collapse.

Patients with ST elevation myocardial infarction (STEMI) require rapid identification and triage to initiate reperfusion therapy. Walk-in STEMI patients have longer treatment times compared to emergency medical service (EMS) transported patients. While effective triage of large numbers of critically ill patients in the emergency department is often cited as the reason for treatment delays, additional factors have not been explored. The purpose of this study was to evaluate baseline demographic and clinical differences between walk-in and EMS-transported STEMI patients and identify factors associated with prolonged door to balloon (D2B) time in walk-in STEMI patients. ⋯ Baseline differences exist between walk-in and EMS-transported STEMI patients undergoing primary percutaneous coronary intervention (PCI). Hospital entry mode was the most important predictor for prolonged treatment times for primary PCI, independent of age, Latino ethnicity, heart rate, systolic blood pressure and initial troponin value. Prolonged door to ECG and ECG to CL activation times are modifiable factors associated with prolonged treatment times in walk-in STEMI patients. In addition to promoting the use of EMS transport, efforts are needed to rapidly identify and expedite the triage of walk-in STEMI patients.

Mental health patients boarding for long hours, even days, in United States emergency departments (EDs) awaiting transfer for psychiatric services has become a considerable and widespread problem. Past studies have shown average boarding times ranging from 6.8 hours to 34 hours. Most proposed solutions to this issue have focused solely on increasing available inpatient psychiatric hospital beds, rather than considering alternative emergency care designs that could provide prompt access to treatment and might reduce the need for many hospitalizations. One suggested option has been the "regional dedicated emergency psychiatric facility," which serves to evaluate and treat all mental health patients for a given area, and can accept direct transfers from other EDs. This study sought to assess the effects of a regional dedicated emergency psychiatric facility design known at the "Alameda Model" on boarding times and hospitalization rates for psychiatric patients in area EDs. ⋯ The results of this study indicate that the Alameda Model of transferring patients from general hospital EDs to a regional psychiatric emergency service reduced the length of boarding times for patients awaiting psychiatric care by over 80% versus comparable state ED averages. Additionally, the psychiatric emergency service can provide assessment and treatment that may stabilize over 75% of the crisis mental health population at this level of care, thus dramatically alleviating the demand for inpatient psychiatric beds. The improved, timely access to care, along with the savings from reduced boarding times and hospitalization costs, may well justify the costs of a regional psychiatric emergency service in appropriate systems.

Non-contrast computed tomography (CT) is widely regarded as the gold standard for diagnosis of urolithiasis in emergency department (ED) patients. However, it is costly, time-consuming and exposes patients to significant doses of ionizing radiation. Hydronephrosis on bedside ultrasound is a sign of a ureteral stone, and has a reported sensitivity of 72-83% for identification of unilateral hydronephrosis when compared to CT. The purpose of this study was to evaluate trends in sensitivity related to stone size and number. ⋯ In a population with CT-proven urolithiasis, ED bedside ultrasonography had similar overall sensitivity to previous reports but showed better sensitivity with increasing stone size and number. We identified 100% of patients with stones ≥6 mm that would benefit from medical expulsive therapy by either the presence of hematuria or abnormal ultrasound findings.
