    Abstract Objective: Examine the nature of domestic and family violence (DFV) presentations to an ED in the Northern Territory and identify potential gaps in service delivery.
    Methods: Prospective descriptive study of DFV presentations in November 2021.
    Results: A total of 70 presentations were identified, representing 1.2% of all presentations aged 16 years and older. Disproportionately impacted were First Nations people (90%), women (77.1%) and those aged less than 40 years (67.1%). Most (81.4%) arrived outside of business hours and only 37.1% were assessed by the social worker. Case complexity was increased by high rates of homelessness (30%), concurrent alcohol consumption (44.3%) and pregnancy (11.1% of females). More than a third (37.1%) had attended on one to four occasions in the previous 6 months with a DFV-related injury. Compared to non-DFV attendances, the median ED length of stay was approximately twice as long (456 vs 210 min), admissions rates to the ED short stay unit five times higher (25.7% vs 5.7%; P < 0.01, odds ratio [OR] = 5.7 and 95% confidence interval [CI] = 3.3-9.8) and rates of self-discharge prior to completion of care 9 times higher (12.9% vs 1.5%; P < 0.01, OR = 9.5 and 95% CI = 4.6-19.7).
    Conclusion: The data highlights the need for a 24 h trauma-informed, culturally safe and integrated service to support people experiencing DFV. This could be achieved by a specialist unit designed and staffed by First Nations health practitioners.

    Abstract Objective: Assess the impact of Northern Territory alcohol policy changes to ED utilisation at Royal Darwin-Palmerston Regional Hospitals.
    Methods: Interrupted time series analysis explored trends in monthly ED attendance numbers and the proportion self-discharging prior to policy changes (September 2016 to August 2017) and after three sequential interventions; the Banned Drinker Register, introduced September 2017, system changes to the sobering shelter, January 2018, and the minimum unit floor price (MUFP), October 2018. A targeted cohort of attendances transported by police as an alternative to the sobering shelter or police watch-house when there is a medical concern was selected as they are likely impacted by all policy changes.
    Results: Police transported 1176 patients on 2070 occasions from September 2016 to March 2019. There was a downward trend in monthly attendances across the study period, with no significant change attributable to the Banned Drinker Register, a significant step decrease with the sobering shelter changes (P = 0.002), and a significant gradual decrease following the MUFP (P = 0.025). This represented an immediate decrease of 3.82 attendances per month/10 000 residents following the sobering shelter changes and a gradual decrease of 0.92 attendances/10 000 residents after the MUFP. Rates of self-discharge were high, 45% in the pre-intervention phase, decreasing to 28% following the MUFP but this trend did not reach significance with any intervention.
    Conclusion: The sequential introduction of broad sweeping alcohol policy changes introduced by the Northern Territory government was associated with significant reductions in ED utilisation. The proximity of the introduction of interventions creates difficulties identifying individual policy influence.

    Abstract Objective: Determine clinical risk for patients presenting to Royal Darwin Hospital ED when they cannot be cared for at the police watch-house (WH) or sobering-up-shelter (SUS) because of a medical concern.
    Methods: This is a retrospective cohort study of police arrivals from May to July 2016. Data collection included demographics and presumed cause of intoxication. Outcomes used as markers of risk were departure status, return visit within 24 h and frequency of ED attendance over 3 months. Social determinants of poor health were collected for the June cohort.
    Results: There were 247 attendances with police by 170 patients. Most were alcohol affected (monthly rates between 83% and 92%). The 'did not wait/left at own risk' rate was high (41-44% vs 7.7%; P < 0.001) and hospital admission rates low (2-7% vs 29%; P < 0.001). Rates of representation (20% within 24 h), ED attendance (≥73% had a further visit within 3 months), comorbidities (46% with three or more chronic diseases), homelessness (66%) and alcohol dependence (85%) were high. Patients presenting more than five times over 3 months were less likely to wait (odds ratio 2.4, 95% confidence interval 1.1-5.2, P = 0.03).
    Conclusion: This is a common presentation at Royal Darwin Hospital ED by a patient group with high levels of comorbidity, homelessness and alcohol dependence. Nearly half self-discharged prior to medical assessment. These patients frequently re-attend the same facilities and enter into a cycle of non-intervention. Case management across services is needed to improve the opportunity that these patients receive appropriate medical, social and addiction interventions.

    Abstract Aim: To examine the impact of a 'next day' outpatient clinic, the Early Pregnancy Problem Service, on patients presenting to the Emergency Department with pain or bleeding in the first trimester of pregnancy. This clinic was established in June 1996.
    Methods: This was a retrospective study involving patients presenting to the Emergency Department with pain or bleeding in early pregnancy. Data was collected from the Emergency Department Information System and the medical records and then compared over the same 2-month periods in different years. These were in, 1996 (preclinic), 1997, 2000 and 2003. The primary outcome was length of stay in the Emergency Department for women with first trimester pain or bleeding that did not require hospital admission. Secondary outcomes were the proportion of such patients presenting and re-presenting to the Emergency Department.
    Results: Following establishment of the clinic there was a significant reduction in the median length of stay in the Emergency Department for patients who were discharged (136 mins in 1996 vs 107 mins in 2003; P < 0.001). There were non-significant reductions in the proportion of patients presenting to the Emergency Department (1.5% in 1996 vs 1.1% in 2003; P = 0.09) and the number re-presenting (16% in 1996 vs 7% in 2003; P = 0.15).
    Conclusion: Following the introduction of the Early Pregnancy Problem Service, women presenting with first trimester pain or bleeding who did not require emergency hospital admission spent significantly less time in the Emergency Department.

  5. Article: The Effect of Agonists and Antagonists of Platelet Aggregation on von Willebrand Factor-Mediated Platelet Agglutination

    Abstract: Ristocetin-induced platelet agglutination (RIPA) in EDTA-treated citrated platelet-rich plasma was reduced to 49 ± 11% by 1.25 ΜM ADP, 41 ± 14% by 1 ΜM A 23187, and 26 ± 7% by 0.1 Μg/ml platelet activating factor (PAF). The effect of 5-110 ΜM epinephrine ...

    Abstract Ristocetin-induced platelet agglutination (RIPA) in EDTA-treated citrated platelet-rich plasma was reduced to 49 ± 11% by 1.25 ΜM ADP, 41 ± 14% by 1 ΜM A 23187, and 26 ± 7% by 0.1 Μg/ml platelet activating factor (PAF). The effect of 5-110 ΜM epinephrine was not dose-dependent, but varied between donors, with RIPA from 56-100% of the control. The inhibitory effects of these agonists were not altered by prior treatment of platelets with aspirin. Prior addition of 200 ΜM ATP (an ADP receptor antagonist acting at both high and low affinity ADP receptors) prevented the inhibitory action of ADP but not that of A 23187 or PAF, suggesting that the inhibitory actions of the latter are not mediated by released ADP. As 700 ΜM 8-bromoadenosine 5-diphosphate (an ADP receptor antagonist acting mainly at the high affinity receptor) did not prevent ADP-induced inhibition of RIPA, interaction of ADP with the low affinity receptor is presumably responsible for its inhibitory action. As A 23187, but not phorbol myristate acetate (0.1 ΜM) inhibited RIPA, an increase in intracellular calcium ions rather than direct stimulation of protein kinase C appears to mediate agonist-induced inhibition. Cytochalasin B (10.5-21 ΜM), dibucaine (0.5-1 mM), and prostaglandin E 1 (25 nM), added before or after the agonist, prevented or reversed ADP-, A23187-, and PAF-induced inhibition of RIPA, suggesting that the state of the platelet cytoskeleton affects inhibition. N-ethylmaleimide (0.25-0.5 mM), an agent that can penetrate cell membranes and block sulphydryl groups, prevented or reversed ADP, A 23187- and PAF-induced inhibition of RIPA, but 0.5 mM dithionitrobisbenzoic acid, a non-penetrating sulphydryl blocker, had no effect. Diamide (0.1-0.5 mM), an agent that can crosslink cytoskeletal proteins by oxidation of sulphydryl groups, reduced RIPA. Thus an increase in intracellular calcium ions with resultant cytoskeletal changes and reorganisation of intracellular sulphydryl groups may mediate the inhibitory action of agonists on RIPA.
