Patterns of emergency department use in rural and metropolitan New South Wales from 2012 to 2018

Geographic variation in emergency department presentations among youth (10-24 years), New South Wales 2019: An epidemiological study

OBJECTIVE

To characterise ED presentations among youth in New South Wales (NSW) by geographic remoteness for 2019 and determine if intra-regional (inland vs coastal) variations exist.

METHODS

A population-based, retrospective descriptive analysis of 2019 Emergency Department Data Collection registry data for state-wide emergency presentations to NSW public hospitals among NSW residents aged 10-24 years was undertaken. Local government areas of residence were classified as major city, coastal regional, inland regional or remote. Sex and age-adjusted ED presentation rates were modelled according to geographical classification, using negative binomial regression.

RESULTS

In 2019, 178 public ED facilities in NSW received 479 880 presentations from NSW residents aged 10-24 years. ED presentation rates in regional and remote areas were more than twice (incidence rate ratio 2.23, 95% confidence interval 2.08-2.39) and four times (incidence rate ratio 4.32, 95% confidence interval 3.84-4.87) that, respectively, of major cities. Compared to major cities, youth presenting to regional and remote facilities spent 36% and 60% less time in ED, respectively, with presentations less likely to be deemed critical, occur after-hours or result in hospital admission. Variation between inland and coastal regional indicators was minimal.

CONCLUSIONS

Patterns of ED utilisation between major city, regional and remote youth were distinctly different, but not so between coastal and inland regional youth. Further research could better understand ED utilisation among youth and the drivers of higher presentation rates in regional and remote areas.

Emergency presentations for older persons with low back pain: An increasing clinical and economic challenge

OBJECTIVE

To determine whether differences exist for older persons presenting to Emergency Departments (EDs) with lower back pain (LBP) in terms of management, health service resource use and cost when compared to younger patients with LBP.

METHODS

Retrospective analysis of routinely collected electronic medical record data from January 2015 to July 2021. Data from 11,098 adults presenting with LBP to two large regional Australian EDs were analysed over a 5-year period. Rates of presentation, investigation, medication use, spinal surgery and cost were assessed for all participants with respect to age groups (over or under 65 years of age), diagnosis and time. Multivariable logistic regression analysis was employed to assess the contribution of presentation characteristics to the risk of inpatient admission and to investigate the variable effect of patient age.

RESULTS

Older people represented 23% (n = 2565) of all LBP presentations, with a growing proportion of presentations over time. More than 1 in 4 patients over 65 were admitted (n = 703, 27%), with CT imaging being proportionately three times more prevalent (24% vs. 6%), and average cost double (AU$3973 vs. $1671) that of the younger population. Consultation by an ED physiotherapist was associated with lower admission risk across all adult presentations (OR 0.52, 95% CI [0.40 to 0.67]).

CONCLUSIONS

Older persons are over-represented amongst gradually increasing rates of LBP presentations to EDs and associated with escalating cost of care and hospital resource use. Older patients present a different clinical and economic profile to younger patients, supporting the provision of individualised management recommendations.

Patterns of emergency department use in rural and metropolitan New South Wales by socioeconomic status: A population-based study

OBJECTIVE

To investigate the patterns of ED use in metropolitan and rural New South Wales (NSW) by socioeconomic status (SES).

METHODS

We undertook a retrospective, population-based study of de-identified data from the NSW Emergency Department Data Collection (EDDC). The study population comprised of NSW residents who presented to an NSW public hospital ED in 2013-2019 and were registered in the NSW EDDC. Total ED presentations, negative binomial regression modelled annual changes in ED presentations over 2013-2019, and age- and sex-standardised rates of ED presentations in 2019 were assessed.

RESULTS

Overall, between 2013 and 2019, ED presentations increased in metropolitan and rural NSW, with mean annual percentage increases of 3.1% (95% confidence interval [CI] 2.8-3.5) and 2.5% (95% CI 2.0-2.9), respectively. This growth varied by SES, with larger increases observed in higher SES groups. The bulk of presentations in rural NSW were from individuals living in disadvantaged areas. Standardised rates of ED presentations were highest in the most disadvantaged quintiles (SES 1) and progressively decreased with increasing SES in both rural and metropolitan NSW (negative gradients). Rates were higher in rural NSW compared to metropolitan NSW across all SES quintiles for total, low acuity and non-low acuity presentations.

CONCLUSIONS

Negative gradients in rates of ED presentations with increasing SES were observed in both metropolitan and rural NSW. At each SES quintile, rates of ED presentations were higher in rural compared to metropolitan areas. Further research exploring the underlying causal mechanisms leading to increased ED demand in rural NSW and socioeconomically disadvantaged populations is warranted.

Profiling Bispebjerg Acute Cohort: Database Formation, Acute Contact Characteristics of a Metropolitan Hospital, and Comparisons to Urban and Rural Hospitals in Denmark

Purpose

To present a metropolitan cohort, Bispebjerg acute cohort (BAC), and compare patient characteristics and outcomes with patients from urban and rural hospitals in Denmark.

Patients and Methods

We linked data from seven Danish nationwide registries and included all acute contacts to non-psychiatric hospitals in the years 2016–2018. Acute hospital contacts to Bispebjerg and Frederiksberg Hospital constituted BAC, representing a solely metropolitan/urban catchment area. Patient characteristics and outcomes were compared to the rest of Denmark in an urban cohort (UrC) and a rural cohort (RuC), stratified by visit and hospitalization contact types.

Results

We identified 4,063,420 acute hospital contacts in Denmark and BAC constituted 8.4% (n=343,200) of them. BAC had a higher proportion of visits (65.1%) compared with UrC (52.1%) and RuC (45.3%). Patients in BAC more often lived alone (visits: BAC: 34.8%, UrC: 30.6%, RuC: 29.2%; hospitalizations: BAC: 50.8%, UrC: 36.7%, RuC: 37.2%) and had temporary CPR number (visits: BAC: 4.4%, UrC: 1.9%, RuC: 1.6%; hospitalizations: BAC: 1.5%, UrC: 0.9%, RuC: 0.8%). Visit patients in BAC were younger (BAC: 36, UrC: 42, RuC: 45 years, median), more often students (BAC: 18.0%, UrC: 14.0%, RuC: 12.5%), and had more contacts due to infectious diseases (BAC: 19.8%, UrC: 14.1%, RuC: 6.2%) but less due to injuries (BAC: 40.0%, UrC: 43.8%, RuC: 60.7%). Hospitalized patients in BAC had higher median age (BAC: 64, UrC: 61, RuC: 64 years) and fewer were in employment than in UrC (BAC: 26.1%, UrC: 32.1%, RuC: 28.1%). BAC Hospitalizations had a lower death rate within 30 days than in RuC (BAC: 3.0% [2.9–3.1%], UrC: 3.1% [3.0–3.1%], RuC: 3.4% [3.3–3.4%]), but a higher readmission-rate (BAC: 20.5% [20.3–20.8%], UrC: 17.3% [17.2–17.4%], RuC: 17.5% [17.5–17.6%]).

Conclusion

Significant differences between BAC, urban, and rural cohorts may be explained by differences in healthcare structure and sociodemographics of the catchment areas.

Critical care resource use associated with tourism in Central Australia

OBJECTIVE

Tourism to regional and remote Australia is increasing. Its impact on regional critical care services is incompletely understood. We describe tourist admissions and their impact on critical care resources relative to the local population.

DESIGN

Single-centre retrospective study using prospectively collected data from January 2009 to December 2018.

SETTING

Australian regional intensive care unit.

PARTICIPANTS

All critical care admissions for patients aged over 18 years for whom postcode data were available were included.

OUTCOME MEASURES

Primary outcome was hospital mortality. Secondary outcomes examined resource use (intensive care unit and hospital length of stay, mechanical ventilation, interhospital transfer) and admission diagnosis.

RESULTS

Tourists comprise 6.1% of critical care admissions, occupying 5.7% of intensive care unit bed days. They were less likely to be Indigenous (6.3% vs 72.7%), but older (61.5 vs 49.2 years) and male (65.4% vs 52.6%). They were more frequently admitted following acute myocardial infarction (14.2% vs 8.9%) or trauma (20.0% vs 5.0%). There was no difference in hospital mortality (2.9% vs 4.0%) or intensive care unit mortality (2.4% vs 1.8%); however, tourists were more than twice as likely to require interhospital transfer (31.7% vs 14.0%). These findings persisted after adjustment for illness severity.

CONCLUSION

Tourists are an appreciable caseload of this regional intensive care unit and are more likely to require interhospital transfer. There was no difference in mortality. Further research is required across regional and rural Australia to better understand the epidemiology and impact of tourism on critical care resources, and the economic implications of becoming unwell in a regional area.

Rural emergency departments: A systematic review to develop a resource typology relevant to developed countries

OBJECTIVE

Despite low patient numbers, rural emergency departments have a similar diversity of case presentations as urban tertiary hospitals, with the need to manage high-acuity cases with limited resources. There are no consistent descriptions of the resources available to rural emergency departments internationally, limiting the capacity to compare clinical protocols and standards of care across similarly resourced units. This review aimed to describe the range of human, physical and specialist resources described in rural emergency departments in developed countries and propose a typology for use internationally.

DESIGN AND SETTING

A systematic literature search was performed for journal articles between 2000 and 2019 describing the staffing, access to radiology and laboratory investigations, and hospital inpatient specialists.

RESULTS

Considerable diversity in defining rurality and in resource access was found within and between Australia, New Zealand, Canada and USA.

DISCUSSION

A typology was developed to account for (a) emergency department staff on-floor, (b) emergency department staff on-call, (c) physical resources and (d) access to a specialist surgical service. This provides a valuable tool for relevant stakeholders to effectively communicate rural emergency department resources within a country and internationally.

CONCLUSION

The proposed five-tiered typology draws together international literature regarding rural emergency department services. Although further research is required to test this tool, the formation of this common language allows a base for effective communication between governments, training providers and policy-makers who are seeking to improve health systems and health outcomes.
