Comparative Study
Ethical issues of cardiopulmonary resuscitation: comparison of emergency physician practices from 1995 to 2007.
The objectives were to determine current practice among emergency physicians (EPs) regarding the initiation and termination of cardiopulmonary resuscitative (CPR) efforts and to compare responses to those from a similar study performed in 1996. ⋯ Most EPs attempt to resuscitate patients in cardiopulmonary arrest regardless of poor outcomes, except in cases where a legal advance directive is available. Many EPs' decisions regarding resuscitation are based on concerns of litigation and criticism, rather than professional judgment of medical benefit. Most results did not differ significantly from the previous study of 1995, although more physicians honor legal advance directives than previously noted.

Missing delirium in the emergency department (ED) has been described as a medical error, yet this diagnosis is frequently unrecognized by emergency physicians (EPs). Identifying a subset of patients at high risk for delirium may improve delirium screening compliance by EPs. The authors sought to determine how often delirium is missed in the ED and how often these missed cases are detected by admitting hospital physicians at the time of admission, to identify delirium risk factors in older ED patients, and to characterize delirium by psychomotor subtypes in the ED setting. ⋯ Delirium was a common occurrence in the ED, and the vast majority of delirium in the ED was of the hypoactive subtype. EPs missed delirium in 76% of the cases. Delirium that was missed in the ED was nearly always missed by hospital physicians at the time of admission. Using a delirium risk score has the potential to improve delirium screening efficiency in the ED setting.

Falls represent an increasingly frequent source of injury among older adults. Identification of fall risk factors in geriatric patients may permit the effective utilization of scarce preventative resources. The objective of this study was to identify independent risk factors associated with an increased 6-month fall risk in community-dwelling older adults discharged from the emergency department (ED). ⋯ Falls, recurrent falls, and injurious falls in community-dwelling elder ED patients being evaluated for non-fall-related complaints occur at least as frequently as in previously described outpatient cohorts. Nonhealing foot sores, self-reported depression, not clipping one's own toenails, and previous falls are all associated with falls after ED discharge.

The objective was to investigate the association between statin therapy and mortality in emergency department (ED) patients with suspected infection. ⋯ Patients who were admitted to the hospital with infection and received statin therapy while hospitalized had a significantly lower in-hospital mortality compared to patients who did not receive a statin.

Sonographic thoracic B-lines and N-terminal pro-brain-type natriuretic peptide (NT-ProBNP) have been shown to help differentiate between congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD). The authors hypothesized that ultrasound (US) could be used to predict CHF and that it would provide additional predictive information when combined with NT-ProBNP. They also sought to determine optimal two- and eight-zone scanning protocols when different thresholds for a positive scan were used. ⋯ Bedside thoracic US for B-lines can be a useful test for diagnosing CHF. Predictive accuracy is greatly improved when studies are totally positive or totally negative. A two-zone protocol performs similarly to an eight-zone protocol. Thoracic US can be used alone or can provide additional predictive power to NT-ProBNP in the immediate evaluation of dyspneic patients presenting to the ED.
