Population/socio-demographic characteristics (all ED events data).

  • Year
    • ED events per year have increased over time for both Māori (14.6% to 15.8%) and non-Māori (14.8% to 16.8%, 2006-2012).
  • Gender

    • The gender profile associated with all ED events was similar for Māori (50.9% males and 49.1% females) and non-Māori (51.1% males and 48.8% females).

  • Age
    • A higher proportion of Māori ED events were seen in the younger age groups, compared to non-Māori, particularly those aged 0-4 years (13.3% versus 9.3%) and 15-24 years (22.2% versus 18.0%). In comparison, a higher proportion of non-Māori ED events were seen in those aged ≥75 (12.4% versus 2.3%).
  • NZDep06
    • 49.9% of all Māori ED events were from the 3 most deprived deciles compared to 30.2% of non-Māori ED events.
    • The highest proportion of both Māori and non-Māori ED events were from decile 9 (22.5% versus 16.3%).
    • The lowest proportion of both Māori and non-Māori ED events were from decile 7 (3.9% versus 2.8%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 34.7% of Māori arrived into ED via ambulance, police and helicopter compared to 33.9% of non-Māori.
  • Referral type
    • 11.1% of Māori ED events were referred via a general practitioner compared to 11.4% of non-Māori ED events.
    • 0.6% of Māori ED events were via a hospital transfer compared to 0.5% of non-Māori ED events.
    • 53.1% of Māori ED events were through self-referral compared to 54.2% of non-Māori.
  • Triage category
    • 0.9% of Māori ED events were triaged to be seen immediately compared to 0.7% of non-Māori ED events.
    • 11.5% of Māori ED events were triaged to be seen within 10 minutes compared to 12.1% of non-Māori ED events.
    • Māori and non-Māori had a very similar proportion of ED events triaged to be seen within 30 minutes (36.3% versus 35.1%).
    • 41.0% of Māori ED events were triaged to be seen within 60 minutes compared to 42.0% of non-Māori ED events.
    • 10.4% of Māori ED events were triaged to be seen within 120 minutes compared to 10.2% of non-Māori ED events.

Predictors/markers of care (First ED events data, average/mean).

  • The average ED arrival to assessment time for Māori patients was 66 mins compared to 68 mins for non-Māori.

  • The ED LOS (Length of Stay) for Māori patients was 189 mins compared to 193 mins for non-Māori.

  • The ward LOS for Māori patients was 68 hours compared to 73 hours for non-Māori.

  • 15% of Māori patients encountered access block compared to 19% of non-Māori.

  • 0.4% of Māori patients died in ED or within 10 days of ED discharge compared to 0.6% of non-Māori patients.

  • 4% of both Māori and non-Māori patients re-presented at ED within 72 hours of ED/ward discharge.

  • 2% of both Māori and non-Māori patients had a hospital readmission within 72 hours of ED/ward discharge.

Regression models (First ED events data).

After controlling for year, gender, age at presentation, triage category, NZDep decile, and M3 Index score:

  • The odds of access block for Māori patients is 1.1 times the odds of access block for non-Māori patients.
  • The odds of ED re-presentation within 72 hours of ED/ward discharge for Māori patients is 0.9 times the odds of re-presentation for non-Māori patients.
  • The odds of hospital readmission within 72 hours of ED/ward discharge for Māori patients is 0.9 times the odds of readmission for non-Māori patients.
  • The odds of death for Māori patients in ED or within 10 days of ED discharge is 1.4 times the odds of death for non-Māori patients.
