ItemDon't Label Me: A Qualitative Study of Patients' Perceptions and Experiences of Sedation During Behavioral Emergencies in the Emergency Department(WILEY, 2017-08)OBJECTIVES: Behavioral emergencies are commonly seen in emergency departments (EDs). Acutely agitated patients can be difficult to manage and sedation may be required to decrease dangerous behavior and to ensure the safety of both the patient and the staff. While the experience of staff caring for this population has been reported, patients' experiences with their overall management remains unknown. We aimed to describe the perceptions and experiences of patients regarding the use of sedation during acute behavioral emergencies. METHODS: Face-to-face semistructured interviews were conducted with adults aged 18 years or older, who had received parenteral sedative medication for the management of a behavioral emergency and were deemed capable to participate. The participants were asked about their experiences of receiving care in the ED during the episode and their perceptions of sedation. All interviews were transcribed verbatim and analyzed thematically. RESULTS: Data saturation was reached after 13 interviews. Two broad themes emerged: trusting relationships and needs or wants following sedation. A trusting relationship is built through 1) confidence in care, 2) sedation as an appropriate treatment, 3) insight into own behavior, and 4) humane treatment. Four subthemes of needs or wants were identified: 1) empathy, 2) debrief, 3) addressing concerns, and 4) follow-up. CONCLUSIONS: A trusting relationship was identified as crucial to minimize the negative impact of coercive measures used to manage behavioral emergencies. Participants expressed similar needs to patients presenting with medical problems. This study illustrates their needs for compassionate communication, adequate information about the treatment provided, and follow-up care.

ItemPatient satisfaction with procedural sedation in the emergency department(WILEY, 2017-06)OBJECTIVE: The aim of this study was to determine patient satisfaction with procedural sedation as a function of nature of the procedure and depth of sedation. METHOD: We undertook a prospective observational study of adult patients who received procedural sedation in two EDs (20 month period). The level of sedation was determined by an investigator, using the Observers Assessment of Anaesthesia/Sedation Scale (1 = awake to 6 = no response to noxious stimuli). Patient satisfaction was measured with the Iowa Satisfaction with Anaesthesia Scale after full recovery. This was self-administered, comprised 11 items (e.g. 'I felt pain') and has a score range of -3 (poor satisfaction) to +3 (very satisfied). RESULTS: A total of 163 patients were enrolled (51.2% men, mean age 50.7 years). The median (interquartile range) satisfaction score was 2.7 (0.7). Patient satisfaction was lower among patients who had orthopaedic procedures (median 2.6 vs 2.8, P < 0.01) and among patients who had a pre-sedation opioid (2.6 vs 2.8, P = 0.03). Satisfaction was positively correlated with deeper sedation (Spearman's correlation coefficient 0.49, P < 0.001). Satisfaction also differed significantly between the four most common sedation regimens (P < 0.001). It was greatest among those who were administered propofol with or without fentanyl and least among those who were administered nitrous oxide with or without opioid. Patients sedated with propofol with or without fentanyl had the greatest depths of sedation. There was no difference in satisfaction among patients who were and were not sedated by a consultant (median 2.6 and 2.7, respectively, P = 0.84). CONCLUSION: Generally, the level of patient satisfaction is high. Greater satisfaction is associated with deeper sedation, sedation with propofol and non-orthopaedic procedures.

ItemAdherence to national exercise guidelines by patients attending emergency departments: A multi-site survey(WILEY, 2017-06)OBJECTIVE: The proportion of adults in Australia meeting or exceeding the national guidelines for physical activity has remained relatively static over the past 10 years. The research objective was to measure self-reported physical activity and sedentary behaviour among ED patients in accordance with Australia's current physical activity and sedentary behaviour guidelines, revised in 2014. METHODS: A convenience sample of participants was recruited from three EDs in Melbourne between February and May 2016. Eligible participants were administered the International Physical Activity Questionnaire - Short Form plus researcher-derived questions. Participants were assessed as whether meeting the physical activity guidelines or not, using pre-defined criteria. RESULTS: The proportion of 18-64 year olds meeting all of the physical activity guidelines was 19.0% (95% confidence interval [CI] 15.2-22.8). A majority of participants (63.1%, 95% CI 58.5-67.7) met the aerobic component of the guidelines although only 28.9% (95% CI 24.5-33.3) of participants reported undertaking strength building exercises two or more times per week. Adults in the oldest age group were found to be less likely to engage in muscle strengthening exercises (23.3%, n = 30) than those in the youngest age group (40.0%, n = 60, P = 0.005). Average daily sitting time (minutes) did not differ between men (median = 300) and women (median = 360, P = 0.118). CONCLUSIONS: Overall adherence with physical activity guidelines is low among adults attending the ED. All adults need to be encouraged to undertake muscle strengthening activities, especially adults in older age groups.

ItemRisk Factors for Sedation-related Events During Acute Agitation Management in the Emergency Department(WILEY, 2019-10)OBJECTIVE: The objective was to describe the incidence, nature, and risk factors for adverse events (AEs) among patients who received parenteral sedation for acute agitation in an emergency department (ED) setting. METHODS: We undertook a prospective observational study and a clinical trial of parenteral sedation for the management of acute agitation. We included agitated adult patients who required parenteral sedation from 2014 to 2017 in 12 Australian EDs, excluding those with incomplete information or aged under 18 years. The primary outcome was the number of patients who experienced at least one AE. Multivariable logistic regression was used to determine factors associated with AEs. RESULTS: A total of 904 patients were included in the analyses (62.3% male; median age = 34 years, range = 18 to 95 years). Of these, 144 (15.9%) patients experienced at least one AE. The most common AEs were oxygen desaturation (7.4%), airway obstruction (3.6%), bradycardia (1.9%), hypotension (1.7%), and prolonged QTc interval (1.3%). No deaths or serious AEs were reported. The following factors had an increased adjusted odds ratio (OR) for experiencing an AE: age 65 years and older (OR = 2.8, 95% confidence interval [CI] = 1.2 to 7.2), more than one type of parenteral sedation administered within 60 minutes (OR = 2.1, 95% CI = 1.4 to 3.1), and alcohol intoxication (OR = 1.8, 95% CI = 1.2 to 2.6). CONCLUSIONS: Sedation-related AEs are common, especially respiratory events. Elderly patients, sedation with multiple sedatives within 60 minutes, and alcohol intoxication increased the risk.

ItemCommunity asthma management of emergency department patients: A pilot study of adherence with national consensus guidelines(WILEY, 2018-06)We aimed to determine whether the outpatient management of ED patients with asthma adheres to Australia's Asthma Consensus Guidelines. Adult patients, under treatment for asthma, were administered a validated questionnaire. Data on their outpatient management were collected and analysed descriptively. Of 51 patients, 14 smoked and 35 did not undergo regular GP review. Twenty-one patients had a good understanding of a written asthma action plan although only 15 owned one. Fourteen patients used no preventer medication. Patients were only able to identify a mean of 3.4 asthma triggers. Most patients' management does not adhere to Australian guidelines.

ItemEconomic Evaluation of Midazolam-Droperidol Combination, Versus Droperidol or Olanzapine for the Management of Acute Agitation in the Emergency Department: A Within-Trial Analysis(SPRINGER INTERNATIONAL PUBLISHING AG, 2018-06)BACKGROUND: The combination of midazolam and droperidol has proven superior to droperidol or olanzapine monotherapy in the management of acute agitation in emergency departments (EDs). OBJECTIVE: This is the first economic analysis to evaluate the cost-benefit and cost effectiveness of the midazolam-droperidol combination compared with droperidol or olanzapine for the management of acute agitation in EDs. METHODS: This analysis used data derived from a randomised, controlled, double-blind clinical trial conducted in two metropolitan Australian EDs between October 2014 and August 2015. The economic evaluation was from the perspective of Australian public hospital EDs. The main outcomes included agitation management time and the agitation-free time gained. Sensitivity analyses were undertaken. RESULTS: The midazolam-droperidol combination was the least costly regimen (Australian dollars [AU$]46.25 per patient) compared with the droperidol and olanzapine groups (AU$92.18 and AU$110.45 per patient, respectively). The main cost driver for all groups was the cost of the labour required during the initial adequate sedation. The combination afforded an additional 10-13 min of mean agitation-free time gained, which can be translated to additional savings of AU$31.24-42.60 per patient compared with the droperidol and olanzapine groups. The benefit-cost ratio for the midazolam-droperidol combination was 12.2:1.0, or AU$122,000 in total benefit for every AU$10,000 spent on management of acute agitation. Sensitivity analyses over key variables indicated these results were robust. CONCLUSIONS: The midazolam-droperidol combination may be a cost-saving and dominant cost-effective regimen for the treatment of acute agitation in EDs as it is more effective and less costly than either droperidol or olanzapine monotherapy.
