Canadian Triage and Acuity Scale: testing the mental health categories.

PURPOSE: The study tested the inter-rater reliability and accuracy of triage nurses' assignment of urgency ratings for mental health patient scenarios based on the 2008 Canadian Triage and Acuity Scale (CTAS) guidelines, using a standardized triage tool. The influence of triage experience, educational preparation, and comfort level with mental health presentations on the accuracy of urgency ratings was also explored. METHODS: Study participants assigned urgency ratings to 20 mental health patient scenarios in randomized order using the CTAS. The scenarios were developed using actual triage notes and were reviewed by an expert panel of emergency and mental health clinicians for face and content validity. RESULTS: The overall Fleiss' kappa, the measure of inter-rater reliability for this sample of triage nurses (n=18), was 0.312, representing only fair albeit statistically significant (P<0.0001) agreement. Kendall's coefficient of concordance for the sample was calculated to be 0.680 (P<0.0001), which signifies moderate agreement. Although the sample reported high levels of education, comfort with mental health presentations, and experience, accuracy in urgency ratings measured by the percentage of correct responses ranged from 0.05% to 94% (mean: 54%). Greater accuracy in urgency ratings was recorded for triage nurses who used second-order modifiers and avoided the use of override. CONCLUSION: Specific focus on the use of second-order modifiers in orientation and ongoing education of triage nurses may improve the reliability and validity of the CTAS when used to assign urgency ratings to mental health presentations.

Repeat substance-using suicidal clients-how can we be helpful?

Care of clients with mental health and substance abuse problems accounts for a significant proportion of all emergency department (ED) visits. This qualitative research project sought to understand the ED experiences of men with a history of suicidal behavior and substance abuse and those of the emergency personnel who work with them. Understanding the unique positions of care providers and this client population in the ED setting can assist the social worker to advocate for this highly vulnerable group of clients and to assist an interprofessional team to develop better crisis interventions.

Experiences of substance-using suicidal males who present frequently to the emergency department.

OBJECTIVE: This qualitative study investigated the repeated use of the emergency department (ED) by men with a history of suicidal behaviour and substance abuse to understand the needs and barriers to care for this high-risk group. Identification of common themes from interviews with patients and health care workers can serve as a basis for improved ED-based interventions. METHODS: Using semistructured interviews, patients, ED staff and family physicians were asked about needs of the aformentioned group. Twenty-five patients were interviewed and completed questionnaires regarding their substance use, aggression, parasuicidal behaviour, alexithymia and childhood trauma. In addition, 27 staff members were interviewed. Interviews were tape-recorded, transcribed and qualitatively analyzed using an iterative coding process. RESULTS: Of the 25 patients, 23 (96%) had a mood or anxiety disorder and 18 (75%) had borderline personality disorder. One-half of the patients scored high and another quarter scored moderate on alexithymia testing. The ED was viewed as a last resort despite seeking help. Frustration was felt by both patients and staff regarding difficult communication, especially during an acute crisis. CONCLUSION: The ED plays an important role in the provision of care for men with recurrent suicidal behaviour and substance abuse. Some of the diagnoses and problems faced by these patients are beyond the purview of the ED; however, staff can identify mutual goals for crisis interventions, allow for frequent communication and seek to de-escalate situations through the validation of the stress patients are experiencing.

Responses to written notification during out-of-hospital care trials using waiver of informed consent.

BACKGROUND: Resuscitation research has been allowed to proceed using waiver of consent when compliance with guidelines is assured. In these circumstances, institutional review boards (IRBs) may request notification of enrolled patients. OBJECTIVES: To describe the notification process developed with IRB feedback and implemented in two out-of-hospital randomized controlled trials (RCTs) in a large urban setting. METHODS: This was a descriptive review of two RCTs recruiting a total of 620 patients: the Out-of-hospital Cardiac Arrest Rectilinear Biphasic to Monophasic Damped Sine Defibrillation Waveforms with Advanced Life Support Intervention Trial (ORBIT), which compared rectilinear biphasic and monophasic damped sine waveform for out-of-hospital cardiac arrest, and the Prehospital Pacing versus Conventional Treatment Effectiveness Trial (PrePACE), which compared dopamine and transcutaneous pacing for unstable bradycardia. RESULTS: The ORBIT study enrolled 538 patients. In 44 (8%) patients, contact information could not be obtained. Notification was attempted for 494 (92%) patients; 48 (10%) letters were returned to sender. Researchers were contacted by telephone regarding 37 (8%) subjects: 16 (43%) requested information, 14 (38%) responded positively, and one (3%) did not return follow-up calls. Overall, two (0.4%) were withdrawn from the study. The PrePACE study enrolled 82 subjects. Contact information was unavailable for one (1%). For the remaining 81 patients, four (5%) letters were returned to sender. Researchers were contacted regarding ten (13%) subjects: seven (70%) requested information, two (20%) responded positively, and one (10%) did not return follow-up calls. No patient was withdrawn from the study. CONCLUSIONS: Contact information may be difficult to obtain for up to 20% of out-of-hospital critical patients. In 8% to 13% of cases, patients or designates contacted researchers; most feedback was positive. Frequently, non-study-related information was requested, consuming significant resources. Using this method, fewer than 1% of patients were withdrawn from the studies.
