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

  • Year

    • ED events per year have increased over time for both Māori (12.3% to 15.4%, 2006-2012 and non-Māori (12.0% to 18.0%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was similar for Māori (50.3% males and 49.7% females) and non-Māori (51.6% males and 48.4% females).
  • Age

    • A high proportion of Māori ED events were seen in the younger age groups, compared to non-Māori, particularly those aged 0-4 years (16.6% versus 7.7%) and 15-24 years (19.5% versus 13.4%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly those aged 65-74 years (11.6% versus 5.8%) and those aged ≥75 (17.8% versus 3.7%).

  • NZDep06
    • 81.1% of all Māori ED events were from the 3 most deprived deciles compared to 56.7% of non-Māori ED events.
    • The highest proportion of Māori ED events were from decile 10 (35.3%) and the highest proportion of non-Māori ED events were from decile 8 (25.1%).
    • The lowest proportion of ED events for both Māori and non-Māori were from decile 1 (0.1% and 0.5%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • N/A
  • Referral type
    • 14.2% of Māori ED events were via a general practitioner compared to 16.6% of non-Māori.
    • 4.5% of Māori ED events were via hospital transfer compared to 3.3% of non-Māori ED events.
    • 79.2% of Māori ED events were via self-referral compared to 78.4% of non-Māori.
  • Triage category
    • 0.5% of both Māori and non-Māori ED events were triaged to be seen immediately.
    • A higher proportion of non-Māori ED events were triaged to be seen within 10 minutes compared to Māori (10.6% versus 8.0%).
    • 33.3% of Māori ED events were triaged to be seen within 30 minutes compared to 33.6% of non-Māori.
    • 44.8% of Māori ED events were triaged to be seen within 60 minutes compared to 44.1% of non-Māori.
    • A higher proportion of Māori ED events were triaged to be seen within 120 minutes compared to non-Māori (12.9% versus 10.7%).

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

  • The average ED arrival to assessment time for Māori patients was 51 mins compared to 54 mins for non-Māori.
  • The ED LOS (Length of Stay) for Māori patients was 146 mins compared to 164 mins for non-Māori.
  • The ward LOS for Māori patients was 74 hours compared to 88 hours for non-Māori.
  • 6% of Māori patients encountered access block compared to 8% of non-Māori patients.
  • 0.6% of Māori patients died in ED or within 10 days of ED discharge compared to 0.8% of non-Māori patients.
  • 9% of Māori patients re-presented at ED within 72 hours of ED/ward discharge compared to 8% of non-Māori.
  • 2% of Māori had a hospital readmission within 72 hours of ED/ward discharge compared to 3% of non-Māori.

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 0.9 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 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 1.5 times the odds of death for non-Māori patients.
