    Objective: To characterise the assessment and management of delirium in patients admitted to intensive care units (ICUs) in Australia and New Zealand. Methods: We conducted a multicentre observational point prevalence study across 44 adult Australian and New Zealand ICUs. Data were extracted for all patients in the ICU in terms of assessment and treatment of delirium. ICU-level data were collected regarding the use of explicit protocols related to delirium. Results: We studied 627 patients, with 54% (336/627) having at least one delirium screening assessment performed. The Confusion Assessment Method for the ICU (CAM-ICU) was the most frequently used tool (88%, 296/336). Of patients assessed, 20% (68) were identified to have delirium. Eighteen per cent (111) of patients were administered a drug to manage delirium, with 41% (46) of those receiving a drug having no recorded assessment for delirium on that day. Of the drugs used to treat delirium, quetiapine was the most frequently administered. Physical restraints were applied to 8% (48/626) of patients, but only 17% (8/48) of such patients had been diagnosed with delirium. Most physically restrained patients either did not have delirium diagnosed (31%, 15/48) or had no formal assessment recorded (52%, 25/48) on that day. Conclusions: On the study day, more than 50% of patients had a delirium screening assessment performed, with 20% of screened patients deemed to have delirium. Drugs that are prescribed to treat delirium and physical restraints were frequently used in the absence of delirium or the formal assessment for its presence.

    Safewards in Three Emergency Departments: Evaluation of the adaptation and impact of the Safewards Model in Emergency Departments
    Gerdtz, M ; Daniel, C ; Yap, C ; Knott, J ; Hamilton, B ( 2021-02-01)
    Safewards is a model of practice improvement that has been used to promote a therapeutic response to minimise conflict events in mental health in-patient settings. This pilot project (Safewards ED) evaluated the impact of nine modified Safewards interventions in three emergency departments (EDs) within 2 health services in Victoria, Australia. A mixed method approach including: (a) questionnaire, (b) focus groups, and (c) observational cohort studies of conflict events (code grey) and coercive interventions (restraint and medication used to manage patient behaviour); was used to evaluate the Safewards ED interventions 12 months before and 6 months after the implementation. The aim of the evaluation was to explore the applicability and impact of Safewards ED interventions.

    Dearnaley, D ; Syndikus, I ; Mossop, H ; Khoo, V ; Birtle, A ; Bloomfield, D ; Graham, J ; Kirkbride, P ; Logue, J ; Malik, Z ; Money-Kyrle, J ; O'Sullivan, JM ; Panades, M ; Parker, C ; Patterson, H ; Scrase, C ; Staffurth, J ; Stockdale, A ; Tremlett, J ; Bidmead, M ; Mayles, H ; Naismith, O ; South, C ; Gao, A ; Cruickshank, C ; Hassan, S ; Pugh, J ; Griffin, C ; Hall, E (ELSEVIER SCIENCE INC, 2016-08)
    BACKGROUND: Prostate cancer might have high radiation-fraction sensitivity that would give a therapeutic advantage to hypofractionated treatment. We present a pre-planned analysis of the efficacy and side-effects of a randomised trial comparing conventional and hypofractionated radiotherapy after 5 years follow-up. METHODS: CHHiP is a randomised, phase 3, non-inferiority trial that recruited men with localised prostate cancer (pT1b-T3aN0M0). Patients were randomly assigned (1:1:1) to conventional (74 Gy delivered in 37 fractions over 7·4 weeks) or one of two hypofractionated schedules (60 Gy in 20 fractions over 4 weeks or 57 Gy in 19 fractions over 3·8 weeks) all delivered with intensity-modulated techniques. Most patients were given radiotherapy with 3-6 months of neoadjuvant and concurrent androgen suppression. Randomisation was by computer-generated random permuted blocks, stratified by National Comprehensive Cancer Network (NCCN) risk group and radiotherapy treatment centre, and treatment allocation was not masked. The primary endpoint was time to biochemical or clinical failure; the critical hazard ratio (HR) for non-inferiority was 1·208. Analysis was by intention to treat. Long-term follow-up continues. The CHHiP trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN97182923. FINDINGS: Between Oct 18, 2002, and June 17, 2011, 3216 men were enrolled from 71 centres and randomly assigned (74 Gy group, 1065 patients; 60 Gy group, 1074 patients; 57 Gy group, 1077 patients). Median follow-up was 62·4 months (IQR 53·9-77·0). The proportion of patients who were biochemical or clinical failure free at 5 years was 88·3% (95% CI 86·0-90·2) in the 74 Gy group, 90·6% (88·5-92·3) in the 60 Gy group, and 85·9% (83·4-88·0) in the 57 Gy group. 60 Gy was non-inferior to 74 Gy (HR 0·84 [90% CI 0·68-1·03], pNI=0·0018) but non-inferiority could not be claimed for 57 Gy compared with 74 Gy (HR 1·20 [0·99-1·46], pNI=0·48). Long-term side-effects were similar in the hypofractionated groups compared with the conventional group. There were no significant differences in either the proportion or cumulative incidence of side-effects 5 years after treatment using three clinician-reported as well as patient-reported outcome measures. The estimated cumulative 5 year incidence of Radiation Therapy Oncology Group (RTOG) grade 2 or worse bowel and bladder adverse events was 13·7% (111 events) and 9·1% (66 events) in the 74 Gy group, 11·9% (105 events) and 11·7% (88 events) in the 60 Gy group, 11·3% (95 events) and 6·6% (57 events) in the 57 Gy group, respectively. No treatment-related deaths were reported. INTERPRETATION: Hypofractionated radiotherapy using 60 Gy in 20 fractions is non-inferior to conventional fractionation using 74 Gy in 37 fractions and is recommended as a new standard of care for external-beam radiotherapy of localised prostate cancer.

    Hypofractionated radiotherapy versus conventionally fractionated radiotherapy for patients with intermediate-risk localised prostate cancer: 2-year patient-reported outcomes of the randomised, non-inferiority, phase 3 CHHiP trial
    Wilkins, A ; Mossop, H ; Syndikus, I ; Khoo, V ; Bloomfield, D ; Parker, C ; Logue, J ; Scrase, C ; Patterson, H ; Birtle, A ; Staffurth, J ; Malik, Z ; Panades, M ; Eswar, C ; Graham, J ; Russell, M ; Kirkbride, P ; O'Sullivan, JM ; Gao, A ; Cruickshank, C ; Griffin, C ; Dearnaley, D ; Hall, E (ELSEVIER SCIENCE INC, 2015-12)
    BACKGROUND: Patient-reported outcomes (PROs) might detect more toxic effects of radiotherapy than do clinician-reported outcomes. We did a quality of life (QoL) substudy to assess PROs up to 24 months after conventionally fractionated or hypofractionated radiotherapy in the Conventional or Hypofractionated High Dose Intensity Modulated Radiotherapy in Prostate Cancer (CHHiP) trial. METHODS: The CHHiP trial is a randomised, non-inferiority phase 3 trial done in 71 centres, of which 57 UK hospitals took part in the QoL substudy. Men with localised prostate cancer who were undergoing radiotherapy were eligible for trial entry if they had histologically confirmed T1b-T3aN0M0 prostate cancer, an estimated risk of seminal vesicle involvement less than 30%, prostate-specific antigen concentration less than 30 ng/mL, and a WHO performance status of 0 or 1. Participants were randomly assigned (1:1:1) to receive a standard fractionation schedule of 74 Gy in 37 fractions or one of two hypofractionated schedules: 60 Gy in 20 fractions or 57 Gy in 19 fractions. Randomisation was done with computer-generated permuted block sizes of six and nine, stratified by centre and National Comprehensive Cancer Network (NCCN) risk group. Treatment allocation was not masked. UCLA Prostate Cancer Index (UCLA-PCI), including Short Form (SF)-36 and Functional Assessment of Cancer Therapy-Prostate (FACT-P), or Expanded Prostate Cancer Index Composite (EPIC) and SF-12 quality-of-life questionnaires were completed at baseline, pre-radiotherapy, 10 weeks post-radiotherapy, and 6, 12, 18, and 24 months post-radiotherapy. The CHHiP trial completed accrual on June 16, 2011, and the QoL substudy was closed to further recruitment on Nov 1, 2009. Analysis was on an intention-to-treat basis. The primary endpoint of the QoL substudy was overall bowel bother and comparisons between fractionation groups were done at 24 months post-radiotherapy. The CHHiP trial is registered with ISRCTN registry, number ISRCTN97182923. FINDINGS: 2100 participants in the CHHiP trial consented to be included in the QoL substudy: 696 assigned to the 74 Gy schedule, 698 assigned to the 60 Gy schedule, and 706 assigned to the 57 Gy schedule. Of these individuals, 1659 (79%) provided data pre-radiotherapy and 1444 (69%) provided data at 24 months after radiotherapy. Median follow-up was 50·0 months (IQR 38·4-64·2) on April 9, 2014, which was the most recent follow-up measurement of all data collected before the QoL data were analysed in September, 2014. Comparison of 74 Gy in 37 fractions, 60 Gy in 20 fractions, and 57 Gy in 19 fractions groups at 2 years showed no overall bowel bother in 269 (66%), 266 (65%), and 282 (65%) men; very small bother in 92 (22%), 91 (22%), and 93 (21%) men; small bother in 26 (6%), 28 (7%), and 38 (9%) men; moderate bother in 19 (5%), 23 (6%), and 21 (5%) men, and severe bother in four (<1%), three (<1%) and three (<1%) men respectively (74 Gy vs 60 Gy, ptrend=0.64, 74 Gy vs 57 Gy, ptrend=0·59). We saw no differences between treatment groups in change of bowel bother score from baseline or pre-radiotherapy to 24 months. INTERPRETATION: The incidence of patient-reported bowel symptoms was low and similar between patients in the 74 Gy control group and the hypofractionated groups up to 24 months after radiotherapy. If efficacy outcomes from CHHiP show non-inferiority for hypofractionated treatments, these findings will add to the growing evidence for moderately hypofractionated radiotherapy schedules becoming the standard treatment for localised prostate cancer.

    Knowledge and Power Relations in Older Patients' Communication About Medications Across Transitions of Care
    Ozavci, G ; Bucknall, T ; Woodward-Kron, R ; Hughes, C ; Jorm, C ; Joseph, K ; Manias, E (SAGE PUBLICATIONS INC, 2021-12)
    Communicating about medications across transitions of care is a challenging process for older patients. In this article, we examined communication processes between older patients, family members, and health professionals about managing medications across transitions of care, focusing on older patients' experiences. A focused ethnographic design was employed across two metropolitan hospitals. Data collection methods included interviews, observations, and focus groups. Following thematic analysis, data were analyzed using Fairclough's Critical Discourse Analysis and Medication Communication Model. Older patients' medication knowledge and family members' advocacy challenged unequal power relations between clinicians and patients and families. Doctors' use of authoritative discourse impeded older patients' participation in the medication communication. Older patients perceived that nurses' involvement in medication communication was limited due to their task-related routines. To reduce the unequal power relations, health professionals should be more proactive in sharing information about medications with older patients across transitions of care.

    Simulation-based education for staff managing aggression and high-risk behaviors in children with autism spectrum disorder in the hospital setting: A pilot and feasibility cluster randomized controlled trial
    Mitchell, MJ ; Newall, FH ; Heywood, MG ; Sokol, J ; Williams, KJ (Sciedu Press, 2021-07-15)
    Background and objective: Aggression and high-risk behaviors, which can result in behavioral emergencies, are common in children with autism and can be magnified in the hospital environment. Children with autism, with or without intellectual disability, have complex communication needs which require a sophisticated level of knowledge, understanding and skill from health care professionals. Pediatric acute care nursing staff are often not trained and lack confidence in managing children with autism. The purpose of this study was to conduct a pilot and feasibility cluster randomized controlled trial (RCT) of simulation-based education for staff in managing behavioral emergencies with autism spectrum disorder (ASD) in the hospital setting.Methods: This study used a mixed method, to explore the acceptability and feasibility of delivering a large-scale cluster RCT and assess trial processes including recruitment, completion rates, contamination, and outcome measures. The simulation-based training format comprised two scenarios involving an adolescent with autism, intellectual disability and aggressive behaviors. Two pediatric wards of similar size and patient complexity were selected to participate in the study and randomized to receive either simulation-based education plus web-based education materials or web-based education materials only.  Results: The RCT design is feasible with recruitment, acceptability and completion rates reaching target. Self-perceived baseline levels of confidence in managing aggression in children were mid-range and lower for children with autism and intellectual disability. Forty to fifty percent of intervention participants rated the training highly in terms of developing skills and knowledge respectively. The mean group score for observer ratings of de-escalation across four simulations was 20 out of a possible 35. Data for ward aggression were not collected.Conclusions: Simulation-based education is an acceptable training format for acute care pediatric nurses. This study is feasible to conduct as a cluster RCT with some modifications to this protocol including assessment of baseline differences in confidence. Observer ratings of de-escalation skills indicated that more than one episode of training may be required for acute care pediatric staff to successfully de-escalate aggressive incidents. As such, we will use repeated simulation scenario exercises for each intervention group in the next trial.

    The effect of alternative methods of cardiopulmonary resuscitation - Cough CPR, percussion pacing or precordial thump - on outcomes following cardiac arrest. A systematic review
    Dee, R ; Smith, M ; Rajendran, K ; Perkins, GD ; Smith, CM ; Vaillancourt, C ; Avis, S ; Brooks, S ; Castren, M ; Chung, SP ; Considine, J ; Escalante, R ; Han, LS ; Hatanaka, T ; Hazinski, MF ; Hung, K ; Kudenchuk, P ; Morley, P ; Ng, K-C ; Nishiyama, C ; Semeraro, F ; Smyth, M (ELSEVIER IRELAND LTD, 2021-05)
    BACKGROUND: Cardiopulmonary resuscitation (CPR) improves cardiac arrest survival. Cough CPR, percussion pacing and precordial thump have been reported as alternative CPR techniques. We aimed to summarise in a systematic review the effectiveness of these alternative CPR techniques. METHODS: We searched Ovid MEDLINE, EMBASE and the Cochrane Library on 24/08/2020. We included randomised controlled trials, observational studies and case series with five or more patients. Two reviewers independently reviewed title and abstracts to identify studies for full-text review, and reviewed bibliographies and 'related articles' (using PubMed) of full-texts for further eligible studies. We extracted data and performed risk-of-bias assessments on studies included in the systematic review. We summarised data in a narrative synthesis, and used GRADE to assess evidence certainty. RESULTS: We included 23 studies (cough CPR n = 4, percussion pacing n = 4, precordial thump n = 16; one study studied two interventions). Only two (both precordial thump) had a comparator group ('standard' CPR). For all techniques evidence certainty was very low. Available evidence suggests that precordial thump does not improve survival to hospital discharge in out-of-hospital cardiac arrest. The review did not find evidence that cough CPR or percussion pacing improve clinical outcomes following cardiac arrest. CONCLUSION: Cough CPR, percussion pacing and precordial thump should not be routinely used in established cardiac arrest. In specific inpatient, monitored settings cough CPR (in conscious patients) or percussion pacing may be attempted at the onset of a potential lethal arrhythmia. These must not delay standard CPR efforts in those who lose cardiac output. PROSPERO REGISTRATION NUMBER: CRD42019152925.

    Diagnosis of out-of-hospital cardiac arrest by emergency medical dispatch: A diagnostic systematic review
    Drennan, IR ; Geri, G ; Brooks, S ; Couper, K ; Hatanaka, T ; Kudenchuk, P ; Olasveengen, T ; Pellegrino, J ; Schexnayder, SM ; Morley, P (ELSEVIER IRELAND LTD, 2021-02)
    INTRODUCTION: Cardiac arrest is a time-sensitive condition requiring urgent intervention. Prompt and accurate recognition of cardiac arrest by emergency medical dispatchers at the time of the emergency call is a critical early step in cardiac arrest management allowing for initiation of dispatcher-assisted bystander CPR and appropriate and timely emergency response. The overall accuracy of dispatchers in recognizing cardiac arrest is not known. It is also not known if there are specific call characteristics that impact the ability to recognize cardiac arrest. METHODS: We performed a systematic review to examine dispatcher recognition of cardiac arrest as well as to identify call characteristics that may affect their ability to recognize cardiac arrest at the time of emergency call. We searched electronic databases for terms related to "emergency medical dispatcher", "cardiac arrest", and "diagnosis", among others, with a focus on studies that allowed for calculating diagnostic test characteristics (e.g. sensitivity and specificity). The review was consistent with Grading of Recommendations, Assessment, Development and Evaluation (GRADE) method for evidence evaluation. RESULTS: We screened 2520 article titles, resulting in 47 studies included in this review. There was significant heterogeneity between studies with a high risk of bias in 18 of the 47 which precluded performing meta-analyses. The reported sensitivities for cardiac arrest recognition ranged from 0.46 to 0.98 whereas specificities ranged from 0.32 to 1.00. There were no obvious differences in diagnostic accuracy between different dispatching criteria/algorithms or with the level of education of dispatchers. CONCLUSION: The sensitivity and specificity of cardiac arrest recognition at the time of emergency call varied across dispatch centres and did not appear to differ by dispatch algorithm/criteria used or education of the dispatcher, although comparisons were hampered by heterogeneity across studies. Future efforts should focus on ways to improve sensitivity of cardiac arrest recognition to optimize patient care and ensure appropriate and timely resource utilization.

    GRADE notes: How to use GRADE when there is "no" evidence? A case study of the expert evidence approach
    Mustafa, RA ; Garcia, CAC ; Bhatt, M ; Riva, JJ ; Vesely, S ; Wiercioch, W ; Nieuwlaat, R ; Patel, P ; Hanson, S ; Newall, F ; Wiernikowski, J ; Monagle, P ; Schunemann, HJ (ELSEVIER SCIENCE INC, 2021-09)
    OBJECTIVES: One essential requirement of trustworthy guidelines is that they should be based on systematic reviews of the best available evidence. The GRADE Working Group has provided guidance for evaluating the certainty of evidence based on several domains. However, for many clinical questions, published evidence may be limited, too indirect or simply not exist. In this brief report (GRADE notes), we describe our method of developing evidence-based recommendations when publisheddirect evidence was lacking. STUDY DESIGN AND SETTING: When direct published literature was absent, an expert evidence survey was administered to panel members about their unpublished observations and case series. Focus was on collecting data about cases and outcome, not panel opinions. RESULTS: Out of 26 questions prioritized by the panel for pediatric venous thromboembolism, 12 had no, very limited, or very low certainty of evidence to inform them. The panel survey was administered for these questions. CONCLUSIONS: Areas of sparse evidence often reflect key questions that are critical to address in clinical practice guidelines due to the uncertainty among health care providers. The expert evidence approach used in this study is one method for panels totransparently deal with the lack of published evidence to directly inform recommendations.
