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

  • Year

    • ED events per year have increased over time for both Māori (12.4% to 15.2%, 2006-2012) and non-Māori (12.7% to 15.6%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was slightly different for Māori (50.9% males and 49.1% females) and non-Māori (53.3% males and 46.7% 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 (17.7% versus 9.1%) and 15-24 years (20.3% versus 15.1%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly those aged 65-74 years (9.5% versus 4.8%) and those aged ≥75 (13.9% versus 3.1%).

  • NZDep06
    • 76.0% of all Māori ED events were from the 3 most deprived deciles compared to 46.7% of non-Māori ED events.
    • The highest proportion of ED events for both Māori and non-Māori were from decile 10 (40.1% and 17.1%).
    • The lowest proportion of ED events for both Māori and non-Māori were from decile 1 (0.8% and 3.6%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 83.5% of Māori ED events arrived via self-presentation compared to 76.0% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, helicopter and police compared to Māori (23.5% versus 15.7%).
  • Referral type
    • 9.4% of Māori ED events were via a general practitioner compared to 11.8% of non-Māori.
    • 2.3% of Māori ED events were via hospital transfer compared to 3.7% of non-Māori.
    • 85.0% of Māori ED events were through self-referral compared to 80.3% of non-Māori.
  • Triage category
    • 0.3% of Māori ED events were triaged to be seen immediately compared to 0.2% of non-Māori ED events.
    • A similar proportion of Māori and non-Māori ED events were triaged to be seen within 10 minutes (4.5% versus 5.0%).
    • 34.5% of Māori ED events were triaged to be seen within 30 minutes compared to 34.6% of non-Māori.
    • 45.6% of Māori ED events were triaged to be seen within 60 minutes compared to 42.4% of non-Māori.
    • 15.1% of Māori ED events were triaged to be seen within 120 minutes compared to 17.8% of non-Māori.

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

  • The average ED arrival to assessment time for Māori patients was 39 mins compared to 35 mins for non-Māori.
  • The ED LOS (Length of Stay) for Māori patients was 118 mins compared to 119 mins for non-Māori.
  • The ward LOS for Māori patients was 70 hours compared to 71 hours for non-Māori.
  • 9% of both Māori and non-Māori patients encountered access block.
  • 0.4% of Māori patients died in ED or within 10 days of ED discharge compared to 0.5% of non-Māori patients.
  • 10% of Māori patients re-presented at ED within 72 hours of ED/ward discharge compared to 12% of non-Māori.
  • 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 1.2 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 1.0 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 1.0 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 1.9 times the odds of death for non-Māori patients.
