Clinical risk for substance-affected patients attending an emergency department in the Northern Territory with police: A quality improvement initiative

Characteristics and outcomes of patient presentations to the emergency department via police: A scoping review

BACKGROUND

As emergency department (ED) presentations continue to rise, understanding the complexities of vulnerable populations such as people brought in by police (BIBP) is crucial. This review aimed to map and describe the research about people BIBP to the ED.

DESIGN AND METHOD

A scoping review, guided by the Joanna Briggs Institute process, was undertaken. The databases CINAHL, Embase and PubMed were searched between November 2017 and July 2022. The Patterns, Advances, Gaps, Evidence for practice, Research recommendations (PAGER) framework was used to guide the analysis.

RESULTS

A total of 21 studies were included in the review, originating mainly from westernised countries. Examination of patterns across studies revealed four themes: routinely collected data is used to describe people BIBP to the ED; a focus on mental health care; the relationship between care delivery and outcomes; and the role of police in providing emergency care.

CONCLUSION

There is some understanding of the demographic characteristics, clinical characteristics, and outcomes of people BIBP to the ED. Knowledge gaps surrounding sociodemographic factors, prehospital and ED care delivery for people BIBP require further investigation to optimise outcomes for this vulnerable cohort of presenters.

Impact of alcohol policy changes on substance‐affected patients attending an emergency department in the Northern Territory with police

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.
