BackgroundManaging undifferentiated, severe agitation in older adults may require antipsychotic or sedative medications to prevent harm to self or others. Unfortunately, these medications are associated with serious adverse events in older adults, and little is known about their comparative safety.MethodsWe conducted a systematic review to identify comparative effectiveness studies on the safety of medications used in the treatment of severe agitation among older adults in the prehospital or emergency department (ED) setting. We searched eight databases including PubMed, EMBASE, SCOPUS, Cochrane library, CINAHL, Proquest Central, Ageline, and PsycInfo published in or before February 2024. Studies were included if they examined 1st generation antipsychotics, 2nd generation antipsychotics, benzodiazepines, or ketamine. Data were extracted on adverse respiratory events (apnea, hypoxemia, intubation) and other adverse events (arrhythmia, hypotension, worsening delirium, cardiac arrest, and mortality). We report the aggregate occurrence of any adverse events pooled by drug and report odds ratios (ORs) using haloperidol as the reference group.ResultsAmong 8600 studies identified, eight observational studies and one randomized clinical trial met eligibility for further qualitative and quantitative analysis. The observational studies included 838 older adults receiving haloperidol (n = 117), droperidol (n = 129), lorazepam (n = 350), midazolam (n = 68), olanzapine (n = 101), quetiapine (n = 56), and ziprasidone (n = 17). Any adverse events were observed in 16.8% of the patients (141/838). Adverse events were most common among patients receiving midazolam (53%; 36/68). Relative to haloperidol, midazolam significantly increased the risk for any adverse events (OR 5.25 [95% CI: 2.64-10.45]). Quetiapine was the only drug observed to have a lower frequency of adverse events (OR 0.27 [95% CI: 0.08, 0.97]).ConclusionsAdverse drug events are common among older adults receiving antipsychotic or anxiolytic medications for severe agitation. Benzodiazepines, particularly midazolam, pose an excessive risk to older adults requiring pharmacologic treatment for severe agitation.

- Administration, Intravenous

Acute disturbance is a broad term referring to escalating behaviors secondary to a change in mental state, such as agitation, aggression, and violence. Available management options include de-escalation techniques and rapid tranquilization, mostly via parenteral formulations of medication. While the intramuscular route has been extensively studied in a range of clinical settings, the same cannot be said for intravenous (IV); this is despite potential benefits, including rapid absorption and complete bioavailability. This systematic review analyzed existing evidence for effectiveness and safety of IV medication for management of acute disturbances. It followed a preregistered protocol (PROSPERO identification CRD42020216456) and is reported following the guidelines set by Preferred Reporting Items for Systematic Review and Meta-Analysis. APA PsycINFO, MEDLINE, and EMBASE databases were searched for eligible interventional studies up until May 30th, 2023. Data analysis was limited to narrative synthesis since primary outcome measures varied significantly. Results showed mixed but positive results for the effectiveness of IV dexmedetomidine, lorazepam, droperidol, and olanzapine. Evidence was more limited for IV haloperidol, ketamine, midazolam, chlorpromazine, and valproate. There was no eligible data on the use of IV clonazepam, clonidine, diazepam, diphenhydramine, propranolol, ziprasidone, fluphenazine, carbamazepine, or promethazine. Most studies reported favorable adverse event profiles, though they are unlikely to have been sufficiently powered to pick up rare serious events. In most cases, evidence was of low or mixed quality, accentuating the need for further standardized, large-scale, multi-arm randomized controlled trials with homogeneous outcome measures. Overall, this review suggests that IV medications may offer an effective alternative parenteral route of administration in acute disturbance, particularly in general hospital settings.
