We examine access to care for acute depression by insurance status compared to access for acute medical conditions in 9 metropolitan areas in the United States. ⋯ Our findings indicate that the process for obtaining urgent follow-up appointments is systematically different for patients seeking behavioral health care than for those with physical complaints. The use of voicemail, in lieu of having a person answer the telephone, is much more prevalent in behavioral than physical health settings. More work is needed to determine the effect of this practice on depressed individuals and vulnerable populations.

Ketamine is widely used in emergency departments (EDs) to facilitate painful procedures; however, existing descriptors of predictors of emesis and recovery agitation are derived from relatively small studies. ⋯ Early adolescence is the peak age for ketamine-associated emesis, and its rate is higher with IM administration and with unusually high IV doses. Recovery agitation is not age related to a clinically important degree. When we interpreted it in conjunction with the separate airway adverse event phase of this analysis, we found no apparent clinically important benefit or harm from coadministered anticholinergics and benzodiazepines and no increase in adverse events with either oropharyngeal procedures or the presence of substantial underlying illness. These and other results herein challenge many widely held views about ED ketamine administration.

Although ketamine is one of the most commonly used sedatives to facilitate painful procedures for children in the emergency department (ED), existing studies have not been large enough to identify clinical factors that are predictive of uncommon airway and respiratory adverse events. ⋯ Risk factors that predict ketamine-associated airway and respiratory adverse events are high intravenous doses, administration to children younger than 2 years or aged 13 years or older, and the use of coadministered anticholinergics or benzodiazepines.

Comparative Study
Procedural sedation and analgesia outcomes in children after discharge from the emergency department: ketamine versus fentanyl/midazolam.
Although the safety and efficacy of procedural sedation and analgesia in the pediatric emergency department (ED) has been established, the prevalence of adverse events after discharge has not been well studied. We compare the postdischarge incidence of adverse behavioral events and vomiting and hypothesize that ketamine would be associated with increased adverse behaviors. ⋯ Procedural sedation and analgesia in the ED is well tolerated. Though postdischarge vomiting occurs with some frequency, there is a low prevalence of adverse behavioral events after discharge. The use of fentanyl/midazolam was associated with higher adverse behavioral scores.

Rodent and monkey research has shown that ketamine can induce accelerated programmed nerve cell death (apoptosis) when administered in high doses, for prolonged periods, or both. Concern about similar neurotoxicity with human therapeutic use has prompted ongoing investigations by the Food and Drug Administration and National Institutes of Health. If the results of these inquiries are unfavorable to ketamine, such action could ultimately lead to restricted availability of this drug or even its discontinuation from the market. This article discusses the limitations of the published animal research, the challenges in extrapolating such data to humans, the need for further animal and human investigations, and the potential adverse effect on current clinical practice that might result, should the use of ketamine be restricted or the drug removed from the market.
