Equity for Indigenous Australians in intensive care

Indigenous Australians critically ill with sepsis: Characteristics, outcomes, and areas for improvement

BACKGROUND

Aboriginal and Torres Strait Islander Australians have amongst the highest incidence of sepsis globally.

OBJECTIVE

The objective of this study was to describe the characteristics, short- and long-term outcomes of non-Indigenous, Aboriginal Australian and Torres Strait Islander Australians admitted with sepsis to an intensive care unit (ICU) to inform healthcare outcome improvement.

METHODS

A retrospective cohort study of 500 consecutive sepsis admissions to the Cairns Hospital ICU compared clinical characteristics, short-term (before ICU discharge) and long-term (2000 days posthospital discharge) outcomes. Cohort stratification was done by voluntary disclosure of Indigenous status.

RESULTS

Of the 442 individual admissions, 145 (33%) identified as Indigenous Australian. Indigenous and non-Indigenous Australians had similar admission Acute Physiology and Chronic Health Evaluation-3 scores (median [interquartile range]: 70 [52-87] vs. 69 [53-87], P = 0.87), but Indigenous patients were younger (53 [43-60] vs. 62 [52-73] years, P < 0.001) and were more likely to have chronic comorbidities such as type 2 diabetes (58% vs. 23%, P < 0.001), cardiovascular disease (40% vs 28%, P = 0.01), and renal disease (39% vs. 10%, P < 0.001). They also had more hazardous healthcare behaviours such as smoking (61% vs. 45%, P = 0.002) and excess alcohol consumption (40% vs. 18%, P < 0.001). Despite this, the case-fatality rate of Indigenous and non-Indigenous Australians before ICU discharge (13% vs. 12%, P = 0.75) and 2000 days post hospital discharge (25 % vs. 28 %, P = 0.40) was similar. Crucially, however, Indigenous Australians died younger both in the ICU (median [interquartile range] 54 (50-60) vs. 70 [61-76], P < 0.0001) and 2000 days post hospital discharge (58 [53-63] vs. 70 [63-77] years, P < 0.0001).

CONCLUSIONS

Although Indigenous Australians critically ill with sepsis have similar short and long-term mortality rates, they present to hospital, die in-hospital, and die post-discharge significantly younger. Unique cohort characteristics may explain these outcomes, and assist clinicians, researchers and policy-makers in targeting interventions to these characteristics to best reduce the burden of sepsis in this cohort and improve their healthcare outcomes.

Māori end-of-life care in the intensive care unit: A qualitative exploration of nursing perspectives

BACKGROUND

Although goals of care for intensive care patients are typically focussed on restoration of health, 8-15% of patients will die in the intensive care unit (ICU), or soon after transfer to a ward. Early recognition of the need for end-of-life care is vital to identify and support the wishes of the patient and needs of their family. In Aotearoa, New Zealand, Māori are over-represented in admissions to ICUs. Enabling nursing staff to provide culturally safe care to Māori patients and whānau (family, including extended family, kin) at the end of life is critical to upholding Te Tiriti o Waitangi requirements and providing equitable care. This qualitative study explores the experiences of both Māori and non-Māori intensive care nurses, in providing end-of-life care for Māori patients and their whānau.

OBJECTIVES

The objective of this study was to characterise nursing experiences of end-of-life care for Māori in the ICU, identify barriers to and facilitators of confident, competent culturally responsive care, and highlight opportunities to improve preparation and support.

METHODS

Qualitative semistructured interviews were undertaken with nine intensive care nurses (four Māori and five non-Māori) with experience ranging from novice to expert. Data collection and analysis was underpinned by reflexive thematic analysis strengthened by Kaupapa Māori Research values and tikanga best practice.

FINDINGS

Participants described positive and negative experiences in caring for Māori at the end of life. Culturally responsive end-of-life care for Māori in intensive care appears dependent on the acknowledgement and inclusion of whānau as members of the multidisciplinary team. Participants identified a need for high-quality education, supportive unit end-of-life care guidelines and hospital policies, and cultural resources to confidently provide quality end-of-life care.

CONCLUSION

Improved understanding of Māori culture, critical awareness of systems of power and privilege, and the availability of cultural liaisons may increase the confidence and competence of ICU nurses providing care to Māori whānau.

Strengthening approaches to respond to the social and emotional well-being needs of Aboriginal and Torres Strait Islander people: the Cultural Pathways Program

Aboriginal and Torres Strait Islander holistic health represents the interconnection of social, emotional, spiritual and cultural factors on health and well-being. Social factors (education, employment, housing, transport, food and financial security) are internationally described and recognised as the social determinants of health. The social determinants of health are estimated to contribute to 34% of the overall burden of disease experienced by Aboriginal and Torres Strait Islander people. Primary health care services currently 'do what it takes' to address social and emotional well-being needs, including the social determinants of health, and require culturally relevant tools and processes for implementing coordinated and holistic responses. Drawing upon a research-setting pilot program, this manuscript outlines key elements encapsulating a strengths-based approach aimed at addressing Aboriginal and Torres Strait Islander holistic social and emotional well-being.The Cultural Pathways Program is a response to community identified needs, designed and led by Aboriginal and Torres Strait Islander people and informed by holistic views of health. The program aims to identify holistic needs of Aboriginal and Torres Strait Islander people as the starting point to act on the social determinants of health. Facilitators implement strengths-based practice to identify social and cultural needs (e.g. cultural and community connection, food and financial security, housing, mental health, transport), engage in a goal setting process and broker connections with social and health services. An integrated culturally appropriate clinical supervision model enhances delivery of the program through reflective practice and shared decision making. These embedded approaches enable continuous review and improvement from a program and participant perspective. A developmental evaluation underpins program implementation and the proposed culturally relevant elements could be further tailored for delivery within primary health care services as part of routine care to strengthen systematic identification and response to social and emotional well-being needs.

Racial Disparities in End-of-Life Care Between Black and White Adults With Metastatic Cancer

CONTEXT

The comfort of patients with cancer near the end of life (EOL) is often undermined by unnecessary and burdensome treatments. There is a need for more research examining racial disparities in EOL care, especially in regions with a history of racial discrimination.

OBJECTIVES

To examine whether black adults received more burdensome EOL care than white adults in a population-based data set of cancer decedents in Louisiana, a state with a history of slavery and long-standing racial disparities.

METHODS

This was a retrospective analysis of EOL care from the Research Action for Health Network (REACHnet), a regional Patient-Centered Outcomes Research Institute-funded database. The sample consisted of 875 white and 415 black patients with metastatic cancer who died in Louisiana from 2011 to 2017. We used logistic regression to examine whether race was associated with five indicators of burdensome care in the last 30 days of life: chemotherapy use, inpatient hospitalization, intensive care unit admission, emergency department (ED) admission, and mechanical ventilation.

RESULTS

Most patients (85.0%) received at least one indicator of burdensome care: hospitalization (76.5%), intensive care unit admission (44.1%), chemotherapy (29.1%), mechanical ventilation (23.0%), and ED admission (18.3%). Odds ratios (ORs) indicated that black individuals were more likely than white individuals to be hospitalized (OR = 1.66; 95% CI = 1.21-2.28; P = 0.002) or admitted to the ED (OR = 1.57; 95% CI = 1.16-2.13; P = 0.004) during their last month of life.

CONCLUSION

Findings have implications for informing health care decision making near the EOL for patients, families, and clinicians, especially in regions with a history of racial discrimination and disparities.

Characteristics and outcomes of patients admitted to regional and rural intensive care units in Australia

Objective: To describe the characteristics and outcomes of patients admitted to regional and rural intensive care units (ICUs). Design, setting and participants: Retrospective database review using the Australian and New Zealand Intensive Care Society Adult Patient Database for admissions between January 2009 and June 2019. Characteristics and outcomes of patients admitted to regional and rural ICUs were compared with metropolitan and tertiary ICUs. Main outcome measures: Primary outcome was hospital mortality. Secondary outcomes included patient characteristics, ICU mortality, ICU and hospital length of stay, need for mechanical ventilation and need for interhospital transfer. Results: Over the sampling period, admissions to regional/rural ICUs averaged nearly 19 000 episodes per annum and comprised 20% of critical care admissions in Australia. Unadjusted mortality was lower, a result that persisted after adjustment for a range of confounders (odds ratio, 0.73; 95% CI, 0.67-0.80; P < 0.01). Admissions are more likely to be emergencies, and patients are more likely to live in areas of relative disadvantage and to require interhospital transfer, but are less likely to require mechanical ventilation. Conclusions: Although illness severity is lower for patients admitted to regional/rural ICUs, hospital mortality after adjustment for a range of confounders is lower. Compared with tertiary ICUs, emergency admissions are more likely, which may have implications for surge capacity during pandemic illness, while mechanical ventilation is less frequently required. Regional/rural ICUs provide care to a substantial proportion of critically ill patients and have a crucial role in the support of regional Australians.

Obstetric admissions to intensive care units in Australia and New Zealand: a registry-based cohort study

OBJECTIVE

Describe the epidemiology of obstetric patients admitted to an Intensive Care Unit (ICU).

DESIGN

Registry-based cohort study.

SETTING

One hundred and eighty-three ICUs in Australia and New Zealand.

POPULATION

Women aged 15-49 years, admitted to ICU between 2008 and 2017, classified as pregnant, postpartum or with an obstetric-related diagnosis.

METHODS

Data were extracted from the Australia and New Zealand Intensive Care Society (ANZICS) Adult Patient Database and national agencies.

MAIN OUTCOME MEASURES

Incidence of ICU admission, cohort characteristics, maternal outcomes and changes over time.

RESULTS

The cohort comprised 16 063 patients. The annual number of obstetric ICU admissions increased, whereas their proportion of total ICU admissions (1.3%) did not change (odds ratio 1.02, 95% CI 0.99-1.04, P = 0.14). There were 10 518 (65%) with an obstetric-related ICU diagnosis, and 5545 (35%) with a non-obstetric ICU diagnosis. Mean (SD) age was 31 (6.4) years, 1463 (9.1%) were Indigenous, 2305 (14%) were transferred from another hospital, and 3008 (19%) received mechanical ventilation. Median [IQR] length of stay in hospital was 5.2 [3.1-7.9] days, which included 1.1 [0.7-1.8] days in ICU. There were 108 (0.7%) maternal deaths, most (n = 97, 90%) having a non-obstetric diagnosis. There was no change in risk-adjusted length of stay or mortality over time.

CONCLUSIONS

Obstetric patients account for a stable proportion of ICU admissions in Australia and New Zealand. These patients typically have a short length of ICU stay and low hospital mortality.

TWEETABLE ABSTRACT

Obstetric patients in Australia/New Zealand ICUs have a short length of ICU stay and low mortality.
