Status epilepticus in Auckland, New Zealand: Treatment patterns and determinants of outcome in a prospective population-based cohort.

OBJECTIVE: Determination of the real-world performance of a health care system in the treatment of status epilepticus (SE). METHODS: Prospective, multicenter population-based study of SE in Auckland, New Zealand (NZ) over 1 year, with data recorded in the EpiNet database. Focus on treatment patterns and determinants of SE duration and 30-day mortality. The incidence, etiology, ethnic discrepancies, and seizure characteristics of this cohort have been published previously. RESULTS: A total of 365 patients were included in this treatment cohort; 326 patients (89.3%) were brought to hospital because of SE, whereas 39 patients (10.7%) developed SE during a hospital admission for another reason. Overall, 190 (52.1%) had a known history of epilepsy and 254 (70.0%) presented with SE with prominent motor activity. The mean Status Epilepticus Severity Score (STESS) was 2.15 and the mean SE duration of all patients was 44 min. SE self-terminated without any treatment in 84 patients (22.7%). Earlier administration of appropriately dosed benzodiazepine in the pre-hospital setting was a major determinant of SE duration. Univariate analysis demonstrated that mortality was significantly higher in older patients, patients with longer durations of SE, higher STESS, and patients who developed SE in hospital, but these did not maintain significance with multivariate analysis. There was no difference in the performance of the health care system in the treatment of SE across ethnic groups. SIGNIFICANCE: When SE was defined as 10 continuous minutes of seizure, overall mortality was lower than expected and many patients had self-limited presentations for which no treatment was required. Although there were disparities in the incidence of SE across ethnic groups there was no difference in treatment or outcome. The finding highlights the benefit of a health care system designed to deliver universal health care.

Use of the Theoretical Domains Framework to explore factors influencing paediatric fever management practices and antipyretic use in New Zealand emergency departments.

AIM: To explore factors influencing fever management practices and antipyretic use among New Zealand Emergency Department (ED) doctors and nurses using the Theoretical Domains Framework (TDF). METHODS: Cross-sectional survey of doctors and nurses across 11 New Zealand EDs. The questionnaire examined eight of 12 TDF domains, based on a generic questionnaire validated to assess TDF-based determinants of health-care professional behaviour. Relevant domains were identified by the frequency of beliefs; the presence of conflicting beliefs within a domain; and the likely strength of impact of a belief on paediatric fever management in the ED. RESULTS: About 602 participants (243 doctors, 353 nurses and 6 unknown) completed the survey (response rate 47.5%). Over half (351/591, 59.6%, 95% confidence interval (CI) 55.5-63.5%) knew the content of clinical practice guidelines regarding antipyretic use in febrile children (TDF Domain Knowledge), or had been trained to ensure antipyretics are given to febrile children only if they appear distressed (347/592, 58.6%, 95% CI 54.5-62.6%) (Skills). Over 40% (246/590, 95% CI 37.7-45.8%) aim to reduce the fever before discharge (Goals). Most (444/591, 75.1%, 95% CI 71.4-78.6%) participants felt capable of explaining appropriate antipyretic use to parents/care givers (Beliefs about Capabilities). Only a minority (155/584, 26.5%, 95% CI 23.0-30.3%) thought that they can ensure antipyretics are given to febrile children only if they appear distressed when the ED is busy (Environmental Context and Resources). CONCLUSIONS: Using the TDF, we identified factors influencing fever management practices and antipyretic use in the ED. These factors can guide the design of targeted, theory-informed knowledge translation strategies.

Paediatric fever management practices and antipyretic use among doctors and nurses in New Zealand emergency departments.

OBJECTIVES: To assess (i) paediatric fever management practices among New Zealand ED doctors and nurses, including adherence to best practice guidelines; and (ii) the acceptability of a randomised controlled trial (RCT) of antipyretics for relief of discomfort in young children. METHODS: A cross-sectional survey of doctors and nurses across 11 New Zealand EDs. The primary outcome of adherence to paediatric fever management best practice guidelines was assessed with clinical vignettes and defined as single antipyretic use for the relief of fever-related discomfort. RESULTS: Out of 602 participants (243 doctors, 353 nurses and six unknown; response rate 47.5%), only 64 (10.6%, 95% confidence interval [CI] 8.3-13.4%) demonstrated adherence to best practice guidelines. In a febrile settled child with normal fluid intake, the percentage of participants that would use antipyretics doubled with abnormal vital signs (33.7% vs 72.9%, difference -39.2%, 95% CI -44.4% to -34.0%). Most participants would use antipyretics for reduced fluid intake (n = 494, 82.1%, 95% CI 78.8-85.0%) in a febrile settled child. Over half (n = 339, 57.1%, 95% CI 53.0-61.1%) would advise giving antipyretics to prevent febrile convulsions. Most (n = 467, 80.0%, 95% CI 76.5-83.1%) participants agreed that a RCT of antipyretics in febrile children <2 years of age with relief of discomfort as a primary outcome is needed. CONCLUSIONS: Just over 10% of New Zealand ED doctors and nurses demonstrated adherence to paediatric fever management best practice guidelines. A RCT of antipyretics in febrile children <2 years of age specifically addressing relief of discomfort as a primary outcome is strongly supported.

Workplace wellbeing in emergency departments in Aotearoa New Zealand 2020.

AIM: To quantify staff burnout and wellbeing in emergency departments (EDs) throughout New Zealand (NZ). METHODS: A national cross sectional electronic survey of New Zealand clinical and non-clinical ED staff was conducted between 9 March and 3 April 2020. Burnout and wellbeing were assessed using the Copenhagen Burnout Inventory (CBI) and a variety of quantitative measures. Differences between measures were assessed by demography and work role using univariate analyses. Multivariate analyses assessed associations between burnout and wellbeing. RESULTS: 1,372 staff responded from 22 EDs around New Zealand (response rate 43%). Most were female (n=678, 63%), NZ European (n=799, 59%), aged 20-39 years (n=743, 54%) and nurses (n=711, 52%). The overall prevalence of personal burnout was 60%, work-related burnout 55% and patient-related burnout 19%. There was a wide variation of burnout across all EDs. Females and nurses showed the highest degree of burnout by gender and role, respectively. Measures of wellbeing with significant negative correlations with burnout were work-related happiness, work-life balance, job satisfaction and perceived workplace excellence. Work stress had significant positive correlation with burnout. CONCLUSION: New Zealand ED staff have a high degree of burnout. Safety, financial sustainability and quality of care are likely being adversely affected. Stakeholders can be informed by findings from this study to inspire meaningful interventions in EDs and throughout the New Zealand healthcare system.

Facilitators, barriers and opportunities in workplace wellbeing: A national survey of emergency department staff.

INTRODUCTION: Emergency department (ED) staff face daily exposure to the illness, injury, intoxication, violence and distress of others. Rates of clinician burnout are high and associated with poor patient outcomes. This study sought to measure the prevalence of burnout in ED personnel as well as determine the important facilitators of and barriers to workplace wellbeing. METHOD: An anonymous online survey including six open-ended questions on workplace wellbeing was completed by 1372 volunteer participants employed as nurses, doctors, allied health or nonclinical roles at 22 EDs in Aotearoa, New Zealand in 2020. Responses to the questions were analysed using a general inductive approach. RESULTS: The three key themes that characterise what matters most to participants' workplace wellbeing are: (1) Supportive team culture (2) Delivering excellent patient-centred care and (3) Professional development opportunities. Opportunities to improve wellbeing also focused on enhancements in these three areas. CONCLUSION: In order to optimise workplace wellbeing, emergency departments staff value adequate resourcing for high-quality patient care, supportive and cohesive teams and professional development opportunities. Initiatives in these areas may facilitate staff wellbeing as well as improving safety and quality of patient care.

Status epilepticus in Auckland, New Zealand: Incidence, etiology, and outcomes.

OBJECTIVE: To determine the incidence, etiology, and outcome of status epilepticus (SE) in Auckland, New Zealand, using the latest International League Against Epilepsy (ILAE) SE semiological classification. METHODS: We prospectively identified patients presenting to the public or major private hospitals in Auckland (population = 1.61 million) between April 6, 2015 and April 5, 2016 with a seizure lasting 10 minutes or longer, with retrospective review to confirm completeness of data capture. Information was recorded in the EpiNet database. RESULTS: A total of 477 episodes of SE occurred in 367 patients. Fifty-one percent of patients were aged <15 years. SE with prominent motor symptoms comprised 81% of episodes (387/477). Eighty-four episodes (18%) were nonconvulsive SE. Four hundred fifty episodes occurred in 345 patients who were resident in Auckland. The age-adjusted incidence of 10-minute SE episodes and patients was 29.25 (95% confidence interval [CI] = 27.34-31.27) and 22.22 (95% CI = 20.57-23.99)/100 000/year, respectively. SE lasted 30 minutes or longer in 250 (56%) episodes; age-adjusted incidence was 15.95 (95% CI = 14.56-17.45) SE episodes/100 000/year and 12.92 (95% CI = 11.67-14.27) patients/100 000/year. Age-adjusted incidence (10-minute SE) was 25.54 (95% CI = 23.06-28.24) patients/100 000/year for males and 19.07 (95% CI = 16.91-21.46) patients/100 000/year for females. The age-adjusted incidence of 10-minute SE was higher in Maori (29.31 [95% CI = 23.52-37.14]/100 000/year) and Pacific Islanders (26.55 [95% CI = 22.05-31.99]/100 000/year) than in patients of European (19.13 [95% CI = 17.09-21.37]/100 000/year) or Asian/other descent (17.76 [95% CI = 14.73-21.38]/100 000/year). Seventeen of 367 patients in the study died within 30 days of the episode of SE; 30-day mortality was 4.6%. SIGNIFICANCE: In this population-based study, incidence and mortality of SE in Auckland lie in the lower range when compared to North America and Europe. For pragmatic reasons, we only included convulsive SE if episodes lasted 10 minutes or longer, although the 2015 ILAE SE classification was otherwise practical and easy to use.

EpiNet study of incidence of status epilepticus in Auckland, New Zealand: Methods and preliminary results.

The EpiNet project has been commenced to facilitate investigator-led collaborative research in epilepsy. A new Web-based data collection tool has been developed within EpiNet to record comprehensive data regarding status epilepticus and has been used for a study of status epilepticus in Auckland, New Zealand. All patients aged >4 weeks who presented to any of the five public hospitals and the major private hospital within Auckland city (population = 1.61 million) with an episode of status epilepticus between April 6, 2015 and April 5, 2016 were identified using multiple overlapping sources of information. For this study, status epilepticus was defined as any seizure exceeding 10 minutes in duration, or repeated seizures lasting >10 minutes without recovery between seizures. Patients who had either convulsive or nonconvulsive status epilepticus were included. Episodes of status epilepticus were classified according to the 2015 International League Against Epilepsy ILAE status epilepticus classification. A total of 477 episodes in 367 patients were considered as definite or probable status epilepticus; 285 episodes (62%) lasted >30 minutes, which is the duration that has previously been used for epidemiological studies of status epilepticus.

ICare-ACS (Improving Care Processes for Patients With Suspected Acute Coronary Syndrome): A Study of Cross-System Implementation of a National Clinical Pathway.

BACKGROUND: Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals. METHODS: This was a multicenter pragmatic stepped-wedge before-and-after trial in 7 New Zealand acute care hospitals with 31 332 patients investigated for suspected ACS with serial troponin measurements. The implementation was a clinical pathway for the assessment of patients with suspected ACS that included a clinical pathway document in paper or electronic format, structured risk stratification, specified time points for electrocardiographic and serial troponin testing within 3 hours of arrival, and directions for combining risk stratification and electrocardiographic and troponin testing in an accelerated diagnostic protocol. Implementation was monitored for >4 months and compared with usual care over the preceding 6 months. The main outcome measure was the odds of discharge within 6 hours of presentation RESULTS: There were 11 529 participants in the preimplementation phase (range, 284-3465) and 19 803 in the postimplementation phase (range, 395-5039). Overall, the mean 6-hour discharge rate increased from 8.3% (range, 2.7%-37.7%) to 18.4% (6.8%-43.8%). The odds of being discharged within 6 hours increased after clinical pathway implementation. The odds ratio was 2.4 (95% confidence interval, 2.3-2.6). In patients without ACS, the median length of hospital stays decreased by 2.9 hours (95% confidence interval, 2.4-3.4). For patients discharged within 6 hours, there was no change in 30-day major adverse cardiac event rates (0.52% versus 0.44%; P=0.96). In these patients, no adverse event occurred when clinical pathways were correctly followed. CONCLUSIONS: Implementation of clinical pathways for suspected ACS reduced the length of stay and increased the proportions of patients safely discharged within 6 hours.

Use of the EpiNet database for observational study of status epilepticus in Auckland, New Zealand.

The EpiNet project has been established to facilitate investigator-initiated clinical research in epilepsy, to undertake epidemiological studies, and to simultaneously improve the care of patients who have records created within the EpiNet database. The EpiNet database has recently been adapted to collect detailed information regarding status epilepticus. An incidence study is now underway in Auckland, New Zealand in which the incidence of status epilepticus in the greater Auckland area (population: 1.5 million) will be calculated. The form that has been developed for this study can be used in the future to collect information for randomized controlled trials in status epilepticus. This article is part of a Special Issue entitled "Status Epilepticus".

In situ simulation training in emergency departments: what patients really want to know.

Objectives: Despite the use of in situ simulation in the emergency department (ED) for training staff to better manage critical events, little is known about how such training is experienced by patients in the ED during these simulations. We therefore aimed to explore ED patient knowledge and perceptions about staff training for emergencies, as well as their views about simulation generally, and in the ED setting specifically. Methods: In this qualitative study, we used an interpretive approach involving video elicitation and semistructured interviews with patients who were waiting for treatment in the ED. Patients who agreed to participate were asked about their knowledge of simulation and were then shown a short video of a simulated resuscitation from cardiac arrest. We asked participants open-ended questions about their perspectives on the film and their views and about simulation training in the ED. Interviews were audio recorded, transcribed and analysed using thematic analysis. Results: We interviewed 15 participants. Most had little or no prior knowledge of simulation training. Watching the video elicited emotional responses in some participants, and pragmatic responses concerning staff training in others, with most participants viewing simulation training as useful and necessary. Participants said that to avoid unnecessary stress, they would prefer to be notified of when simulations were occurring, and what they could expect to see and hear during simulations. Most participants predicted that they would be willing to wait slightly longer (approximately 30 min) to see a doctor while simulation training was conducted, provided they did not require urgent medical attention. Conclusions: Patient-centred care and care partnerships between patients and healthcare professionals underpin New Zealand healthcare and medical education ideologies. This requires effective communication between all parties, as evident in our study of in situ simulation training in the ED.

Investigating moderate to severe paediatric trauma in the Auckland region.

OBJECTIVE: To investigate differences between paediatric patients with moderate to severe trauma admitted from two paediatric ED, with respect to: demographics, patterns of presentation, mechanism of injury, injury severity scores (ISS), interventions and outcome. METHOD: Retrospective cohort study. Moderate to severe trauma was defined as ISS>9. Paediatric patients admitted to hospital via Starship Children's Emergency or KidzFirst ED, with trauma from 1 May 2003 to 30 April 2004, with ISS>9 were identified using multiple databases. The charts were reviewed and data collected included: demographics, hospital of first presentation, diagnoses, ISS, Paediatric trauma score (PTS), Glasgow coma score (GCS), ventilator hours, length of admission, survival and discharge destination. Descriptive statistics with 95% confidence intervals, Mann-Whitney U-test, chi2-test and Fisher's exact test were used as appropriate. RESULTS: A total of 393 children with moderate to severe trauma were identified using initial search strategies. Of these, 82 children met the inclusion and exclusion criteria for the study; 42 children were admitted via KidzFirst ED and 40 via Starship Children's ED. There was no statistically significant difference in ISS (P=0.86), PTS (P=0.11), GCS (P=0.62), hours on a ventilator (P=0.28) and length of stay (P=0.87) between children admitted from Starship or KidzFirst ED. CONCLUSION: This study suggests that there are no differences in the numbers or severity of paediatric trauma patients admitted from the Starship and KidzFirst ED. This indicates triage is to the closest ED despite having a tertiary referral centre for paediatric trauma available in Auckland City.

Using a template in fracture clinic leads to a sustained improvement in clinical notes.

Changes in shift work patterns have meant that patients presenting to a hospital fracture clinic for follow-up may see a different doctor on each visit. Clear clinical notes are essential in this setting, for both clinical and medico-legal reasons. We tried to improve documentation in the fracture clinic by using an education intervention followed by the introduction of a fracture clinic template. Audits were performed at baseline in January 2002, then in July 2002 after the education intervention, in October 2002 after the template introduction, and finally in March 2005. The combined approach of education and involving staff in design of the template followed by introduction of the template, resulted in a significant and sustained improvement in fracture clinic documentation.

Re-presentation and suicide rates in emergency department patients who self-harm.

OBJECTIVE: To investigate adult presentations to North Shore Hospital, Auckland, New Zealand, following deliberate self-harm, determine re-presentation and suicide rates and investigate the characteristics of those patients who re-present. METHODS: Retrospective review of a cohort of adult patients presenting to North Shore Hospital Emergency Care Centre in Auckland, New Zealand, with deliberate self-harm between 1 January 2001 and 31 August 2002, using data from the National Minimum Data Set and Hospital Discharge Database. The re-presentation rate was calculated as the percentage of patients presenting a second time within 1 year of their index presentation. The suicide rate was calculated as the percentage of patients with a coroner's verdict of suicide within 1 year of their index presentation of deliberate self-harm. RESULTS: There were 1055 presentations by 754 people during the presentation period. Of these 754 people, 136 presented for a second time within a year of the index case (136/754 [18.0%, 95% CI 15.5-21.0]). Eight of the seven hundred and fifty-four people went on to commit suicide within 1 year (8/754 [1.1%, 95% CI 0.5-2.1]). Self-poisoning was the most common method of self-harm. Minor tranquillizers were used more commonly in the group who re-presented. CONCLUSION: Re-presentation and suicide rates in our study were similar to previously published rates. Further research is needed to identify strategies to reduce re-presentations and excess mortality in all people who deliberately self-harm.

Emergency department case-finding for high-risk older adults: the Brief Risk Identification for Geriatric Health Tool (BRIGHT).

OBJECTIVE: The objective was to test the ability of the Brief Risk Identification for Geriatric Health Tool (BRIGHT) to identify older emergency department (ED) patients with functional and physical impairment. METHODS: This was a cross-sectional study in which 139 persons > or = 75 years, who presented to an urban New Zealand ED over a 12-week period, completed the 11-item BRIGHT case-finding tool. Then, within 10 days of their index ED visit, 114 persons completed a comprehensive geriatric assessment. A "yes" response to at least 3 of the 11 BRIGHT items was considered "positive." Primary outcome measures were instrumental activities of daily living (IADL), cognitive performance scale (CPS), and activities of daily living (ADL). RESULTS: The BRIGHT-identified IADL deficit (64% prevalence) with a sensitivity of 0.76, specificity of 0.79, and receiver operating characteristic (ROC) of 0.83 (95% confidence interval [CI] = 0.74 to 0.91, p < 0.01); cognitive deficit (35% prevalence) sensitivity of 0.78, specificity of 0.54, and ROC of 0.66 (95% CI = 0.55 to 0.76, p = 0.006); and ADL deficit (29% prevalence) sensitivity of 0.83, specificity of 0.53, and ROC of 0.64 (95% CI = 0.53 to 0.75, p = 0.020). Positive likelihood ratios (LR+) for the three outcomes of interest were 3.6, 1.7, and 1.8, respectively. Negative likelihood ratios (LR-) were 0.3, 0.4, and 0.3. CONCLUSIONS: The 11-item BRIGHT successfully identifies older adults in the ED with decreased function and may be useful in differentiating elder patients in need of comprehensive assessment.

Use of information technology in New Zealand emergency departments.

OBJECTIVES: To determine previous computer training and current computer confidence of emergency medicine (EM) specialists and trainees, and to determine the accessibility of computer and Internet resources in New Zealand ED. METHODS: A prospective, cross-sectional study of all New Zealand EM specialists and trainees between July 2005 and October 2005, using a 47-item postal questionnaire. Descriptive statistics with 95% confidence intervals were compiled. Fisher's exact test was used to compare proportions, with t-test and Mann-Whitney U-test to compare continuous variables. RESULTS: A total of 226 EM specialists and trainees were sent questionnaires. In total, 144 (62 specialists and 82 trainees) out of 224 were analysed (response rate 64.3%). The majority of respondents (136, 94.4% (95% CI 89.4-97.6)) had access to a computer at home. Almost all respondents (143, 99.3% (95% CI 96.2-100.0)) also had computer access in the ED 24 h/day. The vast majority (140, 97.2% (95% CI 93.0-99.2)) had access to medical educational materials via the Internet in the ED 24 h/day. Most respondents had limited prior computer training. Respondents felt most confident using word processing and e-mail/communications applications, and least confident using statistical and graphics programs. Compared with specialists, trainees were significantly less confident with spreadsheets (P = 0.002), literature searching (P = 0.034), and e-mail/communications (P = 0.040). CONCLUSIONS: Increased access to computer technology has not been parallelled by increased confidence in the use of computers among EM specialists and trainees. Training must address gaps in computer literacy if computer technology is to be used to its full potential.

Comprehension of discharge information for minor head injury: a randomised controlled trial in New Zealand.

AIMS: To investigate health literacy (i.e. understanding medical information) in North Shore Hospital's Emergency Medicine Department patients and to assess differences in comprehension between standard and simplified head injury advice sheets. METHODS: Prospective randomised controlled trial in a convenience sample of adult Emergency Medicine patients presenting to an urban emergency department (ED) in New Zealand. Consented patients were randomised to receive either the standard head injury advice sheet or a shorter, simplified sheet. Participants were asked 10 questions (to test comprehension of advice sheets), demographic data collected, and a Rapid Estimation of Adult Literacy in Medicine test administered. Data analysis included descriptive statistics with 95% confidence intervals, Mann Whitney U test, and regression model analysis. RESULTS: 200 participants. Mean age 43.4 years, 77.5% with 12 or more years of schooling, 84.5% with reading level of high school age or above. No significant differences in demographics, schooling, and reading levels were observed between study groups. The simplified form study group showed significantly higher comprehension scores (p<0.0001). In the regression analysis, factors associated with higher comprehension scores included: the simplified form, higher literacy level, more years of schooling, and younger age group. CONCLUSIONS: Previous studies have highlighted poor literacy levels in ED populations, a factor thought to affect understanding of discharge information. In this study population, where most read at high school level or above, the simplified advice sheet was still better understood. Recommendations for improving discharge information are discussed.

Accidental poisoning in New Zealand.

OBJECTIVE: To examine mortality and morbidity associated with accidental poisoning in New Zealand for the period of 1993-97, and make comparisons with international trends. METHODS: Poison Centre call data, and mortality and public hospital discharge data from the New Zealand Health Information Service were examined. Mortality and hospitalization rates were calculated. Statistical trends were examined using Poisson regression. RESULTS: Poison Centre calls regarding household agents and therapeutics were most frequent. Accidental poisoning with analgesics, antipyretics and antirheumatics (18%) was a common cause of hospitalization. Children under 5 years had the highest hospitalization rates, but were less at risk of death by accidental poisoning than other age groups. Common causes of death from accidental poisoning included utility gas/carbon monoxide (16%), psychotropic agents (16%), and analgesics, etc. (15%). Mortality rates varied between 0.54 and 0.72/100,000 population. CONCLUSION: Mortality rates in New Zealand are lower than in many countries, but hospitalization rates are higher. Possible explanations and prevention implications are discussed.
