In cardiac arrest (CA), time is directly predictive of patients' prognosis. The increase in mortality resulting from delayed cardiopulmonary resuscitation has been quantified minute by minute. Times reported in CA management studies could reflect a timestamping bias referred to as "digit preference". This phenomenon leads to a preference for certain numerical values (such as 2, 5, or 10) over others (such as 13). Our objective was to investigate whether or not digit preference phenomenon could be observed in reported times of the day related to CA management, as noted in a national registry. ⋯ Prospectively collected times were considerably influenced by digit preference phenomenon. Studies that are not based on automatic time recordings and that have not evaluated and considered this bias should be interpretated with caution.

The HEART score for risk stratifying chest pain patients in the emergency department (ED) has been widely adopted in clinical practice, but is often employed with nonconformant serial troponin measurements. ⋯ Our data suggest serial measurement of conventional troponin provides limited added benefit in low risk HEART score patients, regardless of duration and timing of symptoms. Conversely, serial troponin measurement may confer utility in moderate/high risk HEART score patients, particularly those presenting within 3 h of symptoms.

Peer recovery coaches and emergency department utilization in patients with substance use disorders.
Although Emergency Departments (ED) frequently provide care for patients with substance use disorders (SUD), there are many barriers to connecting them with appropriate long-term treatment. One approach to subside risk in this population is the Peer Recovery Coach (PRC). PRCs are individuals with a lived experience of the rehabilitation process and are a powerful resource to bridge this gap in care by engaging patients and their families and providing system navigation, self-empowerment for behavior change, and harm reduction strategies. The purpose of this project is to describe an ED-based PRC program, evaluating its feasibility and efficacy. ⋯ We describe the implementation of an ED-based PRC program for patients with substance use disorders. While we demonstrated that it is feasible for the PRC to engage the patient while in the ED, there was poor follow-up with the program outpatient. For patients with at least one previous SUD visit to the ED, there was a statistically significant reduction in ED utilization after engaging with a PRC while in the ED, suggesting this may be a population that could be targeted to link patients to long term care and decrease repeated ED utilization.

Treating patients with out-of-hospital cardiac arrest (OHCA) requires early prediction of outcome, ideally on hospital arrival, as it can inform the clinical decisions involved. This study evaluated whether partial pressure of carbon dioxide (PCO2) on arrival is associated with outcome at one month OHCA patients. ⋯ High PCO2 on arrival was significantly associated with mortality and unfavorable neurological outcome in OHCA patients.

Retrospective evaluation of ketamine versus droperidol on time to restraint removal in agitated emergency department patients.
Acute agitation and violent behavior in the emergency department (ED) can lead to significant patient morbidity and contribute to the growing problem of workplace violence against health care providers. To our knowledge, there is no available literature directly comparing intramuscular ketamine to intramuscular droperidol in ED patients presenting with undifferentiated agitation. The purpose of this investigation was to compare the effectiveness and safety of these agents for acute agitation in the ED. ⋯ Intramuscular droperidol and intramuscular ketamine were associated with similar times from drug administration to restraint removal in patients presenting to the ED with undifferentiated agitation. Prospective studies are warranted to evaluate IM droperidol and IM ketamine head-to-head as first line agents for acute agitation in the ED.
