Qualitative study of patient experiences and care observations during agitation events in the emergency department: implications for systems-based practice.

OBJECTIVES: Agitation, defined as excessive psychomotor activity leading to aggressive or violent behaviour, is prevalent in the emergency department (ED) due to rising behavioural-related visits. Experts recommend use of verbal de-escalation and avoidance of physical restraint to manage agitation. However, bedside applications of these recommendations may be limited by system challenges in emergency care. This qualitative study aims to use a systems-based approach, which considers the larger context and system of healthcare delivery, to identify sociotechnical, structural, and process-related factors leading to agitation events and physical restraint use in the ED. DESIGN: Qualitative study using a grounded theory approach to triangulate interviews of patients who have been physically restrained with direct observations of agitation events. SETTING: Two EDs in the Northeast USA, one at a tertiary care academic centre and the other at a community-based teaching hospital. PARTICIPANTS: We recruited 25 individuals who experienced physical restraint during an ED visit. In addition, we performed 95 observations of clinical encounters of agitation events on unique patients. Patients represented both behavioural (psychiatric, alcohol/drug use) and non-behavioural (medical, trauma) chief complaints. RESULTS: Three primary themes with implications for systems-based practice of agitation events in the ED emerged: (1) pathways within health and social systems; (2) interpersonal contexts as reflections of systemic stressors on behavioural emergency care and (3) systems-based and patient-oriented strategies and solutions. CONCLUSIONS: Agitation events represented manifestations of patients' structural barriers to care from socioeconomic inequities and high burden of emotional and physical trauma as well as staff members' simultaneous exposure to external stressors from social and healthcare systems. Potential long-term solutions may include care approaches that recognise agitated patients' exposure to psychological trauma, improved coordination within the mental health emergency care network, and optimisation of physical environment conditions and organisational culture.

Characteristics and Severity of Agitation Associated With Use of Sedatives and Restraints in the Emergency Department.

BACKGROUND: Agitated patients frequently present to emergency departments, but limited evidence exists regarding clinical decisions to use chemical sedatives and physical restraints. OBJECTIVE: We examined attributes and levels of agitation impacting thresholds for sedative and restraint use in the emergency setting. METHODS: This was a secondary study focusing on agitation characteristics within a prospective observational study of agitated patients in the emergency department at an urban, tertiary referral center. We recorded scores on 3 validated agitation scales: the Agitated Behavior Scale, the Overt Aggression Scale, and the Severity Scale. Consecutive patients requiring security presence or scoring ≥1 on an agitation scale were enrolled during randomized 8-h blocks. RESULTS: Ninety-five agitation events on unique patients were observed. The median age was 42 years, and 62.1% were male. Highest frequency triage chief complaints were alcohol/drug use (37.9%) and psychiatric (23.2%). Most events (73.7%) were associated with sedative or restraint use. Factors related to treatment course or interactions with staff were commonly cited (56.8%) as the primary etiology for agitation. A logistic regression model found no association between demographics and odds of sedative/restraint use. Overt Aggression Scale scores were associated with significantly higher odds of sedative use (adjusted odds ratio [AOR] 1.62 [range 1.13-2.32]), while Severity Scale scores had significantly higher odds of restraint use (AOR 1.39 [range 1.12-1.73]) but significantly lower odds of sedative use (AOR 0.79 [range 0.64-0.98]). CONCLUSION: External factors may be important targets for behavioral techniques in agitation management. Further study of the Severity Scale scale may allow for earlier detection of agitation and identify causal links between agitation severity and use of sedatives and restraints.
