Homeless status documentation at a metropolitan hospital emergency department.

OBJECTIVE: This study compared the prevalence of homelessness in consecutive patients presenting to a metropolitan hospital ED measured via a prospective housing screen with the prevalence of homelessness determined via retrospective audit of hospital data. Factors that altered the odds of patients being homeless and service outcomes that differed were examined for screened patients. METHODS: All patients presenting to the ED during a 7 day period in 2017 were invited to complete a housing screen. A retrospective audit of all ED presentations during the same period also occurred. Demographic (e.g. age, gender), clinical (e.g. reason for presentation, ED presentation history) and arrival mode (e.g. time, how arrived) predictors of homeless status were examined alongside care outcomes (e.g. ED length of stay, admission and 28 day re-presentation). RESULTS: Of 1208 presenting patients, 504 were prospectively screened and 7.9% were homeless. This compared with 0.8% of ED presentations coded as homeless in the Victorian Emergency Minimum Dataset and 2.3% of the 704 non-screened patients identified as homeless using Victorian Emergency Minimum Dataset Usual Accommodation alongside primary diagnosis and registration address. Within the screened sample, homeless patients were more likely to be male, arrive by emergency ambulance/with police, have a psychosocial diagnosis, and be frequent presenters. Re-presentation within 28 days occurred for 43% of homeless and 15% of not-homeless patients. CONCLUSIONS: Hospital ED administrative data substantially under-recognises the prevalence of homelessness in presenting patients. Standardised use of brief housing screens could improve identification of and provision of support to this often highly vulnerable population.

Security interventions for workplace violence in the emergency department.

OBJECTIVES: Despite a policy of zero tolerance towards workplace violence (WPV) in Australian public hospital EDs, the incidence of WPV continues to increase. The aim of this study was to characterise security responses to WPV within an adult level 4 ED. METHODS: A retrospective single-centre review of episodes of WPV perpetrated by adults occurring within the ED was conducted between 1 January 2013 and 31 December 2015. Cases were identified using a prospectively recorded security register that records all events of security personnel attendance. The presence of police officers on initial presentation was the primary exposure variable. RESULTS: There were 1853 violent episodes committed by 1224 patients requiring security intervention during the study period, with half the episodes (n = 916; 49%) involving perpetrators who had committed at least two or more violent acts during the study period. Most cases (n = 1057, 57%; 95% CI: 55-59) occurred in the absence of police presence. Only 144 (7.8%) cases were managed by the presence of security personnel without physical security interventions. CONCLUSIONS: EDs should not rely on police response to prevent or handle violence. The finding of a high proportion of events being perpetrated by repeat offenders indicate that data sharing between EDs for identification of perpetrators of WPV can be useful for prevention of future episodes. ACEM policy for WPV in EDs should encompass further details on security credentialing and preventive strategies towards minimisation of WPV in the Australian EDs.

Increasing workplace violence in an Australian adult emergency department.

OBJECTIVE: Workplace violence (WPV) is an increasingly concerning occupational hazard within the ED. The aim of the present study was to evaluate the incidence and characteristics of WPV in an adult ED. METHODS: A retrospective cohort study was conducted to identify the incidence of ED WPV in an adult metropolitan ED. Data were obtained from the activity records of security staff from 1 January 2013 to 31 December 2015 for all incidents of patient-perpetrated violence. Data on patients identified from these records as requiring security staff intervention for violence in the ED were collected through an explicit chart review. Data on patient illicit drug or alcohol exposure and acute psychiatric diagnoses were also collected. RESULTS: There were 1853 episodes of patient-perpetrated WPV identified over the study period. The incidence of WPV over the 3 years was 103 (95% CI: 98-108) per 10 000 of the presenting population, with a significant increase from 2013 to 2015 (IRR 1.07; 95% CI: 1.04-1.10; P < 0.01). Drug and/or alcohol exposure was observed in 1145 (61.8%) patients. Among the drug- and/or alcohol-affected violent population, three quarters (840/1145 = 73.4%) did not have a concurrent psychiatric diagnosis that required assessment during the violent presentation. CONCLUSION: The rate of WPV was increasing within this Australian ED during the study period. The majority of violent patients were affected by drugs and/or alcohol in the absence of a psychiatric diagnosis. Interventions to reduce access to and misuse of alcohol and illicit drugs could have a substantial impact on the concerning increase of violence in the ED.

Review article: Workplace violence in the emergency department: A systematic review and meta analysis.

Patient or visitor perpetrated workplace violence (WPV) has been reported to be a common occurrence within the ED. No universal definition of violence or recording of such events exists. In addition ED staff are often reluctant to report violent incidents. The true incidence of WPV is therefore unclear. This systematic review aimed to quantify WPV in EDs. The association of WPV to drug and alcohol exposure was explored. The databases MEDLINE, Embase, PsycInfo and the Cochrane Library were searched from their commencement to 10 March 2016. MeSH terms and text words for ED, violence and aggression were combined. A meta-analysis was conducted on the primary outcome variable-proportion of violent patients among total ED presentations. A secondary meta-analysis used studies reporting on proportion of drug and alcohol affected patients occurring within the violent population. The search yielded a total of 8720 records. A total of 7235 were unique and underwent abstract screening. A total of 22 studies were deemed relevant according to inclusion and exclusion criteria. Retrospective study design predominated, analysing mainly security records and incident reports. The rates of violence from individual studies ranged from 1 incident to 172 incidents per 10 000 presentations. The pooled incidence suggests there are 36 violent patients for every 10 000 presentations to the ED (95% confidence interval 0.0030-0.0043). WPV in the ED was commonly reported. There is wide heterogeneity across the study methodology, definitions and rates. More standardised recording and reporting may inform preventive measures and highlight effective management strategies.

Trauma resuscitation errors and computer-assisted decision support.

HYPOTHESIS: This project tested the hypothesis that computer-aided decision support during the first 30 minutes of trauma resuscitation reduces management errors. DESIGN: Ours was a prospective, open, randomized, controlled interventional study that evaluated the effect of real-time, computer-prompted, evidence-based decision and action algorithms on error occurrence during initial resuscitation between January 24, 2006, and February 25, 2008. SETTING: A level I adult trauma center. PATIENTS: Severely injured adults. MAIN OUTCOME MEASURES: The primary outcome variable was the error rate per patient treated as demonstrated by deviation from trauma care algorithms. Computer-assisted video audit was used to assess adherence to the algorithms. RESULTS: A total of 1171 patients were recruited into 3 groups: 300 into a baseline control group, 436 into a concurrent control group, and 435 into the study group. There was a reduction in error rate per patient from the baseline control group to the study group (2.53 to 2.13, P = .004) and from the control group to the study group (2.30 to 2.13, P = .04). The difference in error rate per patient from the baseline control group to the concurrent control group was not statistically different (2.53 to 2.30, P = .21). A critical decision was required every 72 seconds, and error-free resuscitations were increased from 16.0% to 21.8% (P = .049) during the first 30 minutes of resuscitation. Morbidity from shock management (P = .03), blood use (P < .001), and aspiration pneumonia (P = .046) were decreased. CONCLUSIONS: Computer-aided, real-time decision support resulted in improved protocol compliance and reduced errors and morbidity. Trial Registration clinicaltrials.gov Identifier: NCT00164034.

Management of haemodynamically stable patients with abdominal stab wounds.

OBJECTIVES: Australasian trauma centres receive relatively low numbers of penetrating injuries from stabbings. There is limited agreement regarding protocols to guide the management of haemodynamically stable patients with penetrating injuries. This has resulted in a wide variation in practice with anecdotally high negative laparotomy rates. The aim of the present study was to review the ED procedures, investigations and disposition of this group of patients. METHODS: A retrospective review of all patients presenting with abdominal penetrating injury was undertaken over a 5 year period. Data on demographics, presenting features and management were collected. RESULTS: There were 109 patients who were haemodynamically stable (systolic blood pressure > 90) on arrival to the trauma centre. Diagnostic ED procedures and investigations consisted of wound exploration in 47 (43.1%) patients, focused abdominal sonography in trauma in 44 (40.4%) patients and a CT abdomen in 36 (33.0%) of patients. The sensitivity for focused abdominal sonography in trauma and CT when used together was 77.8%. There were 39 laparotomies performed with a negative laparotomy rate of 23.1%. There were 10 laparoscopies performed, none went on to require a laparotomy. Patients undergoing negative laparotomies spent significantly longer times in hospital than patients managed conservatively or those undergoing laparoscopies. CONCLUSIONS: The number of penetrating abdominal injuries remains low. Imaging alone cannot reliably exclude intraperitoneal injury. A greater utilization of ED wound exploration and laparoscopy based on agreed guidelines could improve management. An algorithm for the management of these patients is suggested.

Complications of intercostal catheter insertion using EMST techniques for chest trauma.

BACKGROUND: The purpose of the present study was to determine the complication rates associated with intercostal catheter insertion (ICI) performed using Early Management of Severe Trauma (EMST) guidelines on trauma patients admitted through The Alfred Trauma Centre. METHODS: The Alfred Trauma Registry identified demographic and clinical data for patients who underwent ICI in the Alfred hospital following admission for trauma. The medical histories were subsequently reviewed for complications resulting from ICI. RESULTS: There were 211 ICI performed on 173 trauma patients at The Alfred Trauma Centre between July 2001 and June 2002. The mean injury severity score was 34. Mean age was 38 (range 15-82 years), with 77% of the patients being men. Chest injury was the result of blunt trauma in 90.2% and penetrating trauma in 9.8%. ICI occurred in the Trauma Centre (84%), operating theatre (6%), intensive care unit (9%) and in the general ward (1%). Eighty per cent of patients had a unilateral ICI. The indications for ICI were pneumothorax (45.7%), haemothorax (15.0%), haemopneumothorax (28.3%) and tension pneumothorax (7.5%). There were no insertional and 11 (5.2%) positional complications. The infection rate was 2.4% comprising two superficial and three deep (empyema thoraces) infections. No statistically significant association was found between infective complications and age, injury severity score (ISS), haemothorax, penetrating trauma, prehospital needle thoracostomy and time to ICI. There was no mortality arising from ICI complications. CONCLUSION: Intercostal catheter insertion for chest trauma performed in accordance with EMST guidelines has a low complication rate. Prehospital prophylactic chest decompression for ventilated patients with chest trauma, using a lateral rather than an anterior approach, may decrease the incidence of untreated tension pneumothorax.
