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

  • Year

    • ED events per year have increased over time for both Māori (10.2% to 17.5%, 2006-2012) and non-Māori (11.8% to 16.3%, 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 (51.4% males and 48.6% 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 (16.6% versus 9.3%) and 15-24 years (20.6% versus 16.0%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly in the 65-74 age group (8.8% versus 4.5%) and those aged ≥75 (15.2% versus 3.3%).

  • NZDep06
    • 51.7% of all Māori ED events were from the 3 most deprived deciles compared to 31.8% of non-Māori ED events.
    • The highest proportion of both Māori and non-Māori ED events were from decile 7 (24.9% versus 26.0%).
    • The lowest proportion of Māori ED events were from decile 2 (1.1%) and the lowest proportion of non-Māori ED events were from decile 4 (2.3%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 62.1% of Māori ED events arrived via self-presentation compared to 58.8% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, police and helicopter compared to Māori (16.8% versus 11.8%).
  • Referral type
    • 2.7% of Māori ED events were referred via a general practitioner compared to 3.9% of non-Māori.
    • 1.0% of Māori ED events were via hospital transfer compared to 0.7% of non-Māori ED events.
    • Māori ED events had a higher proportion of self-referral compared to non-Māori (43.6% versus 40.4%).
  • Triage category
    • 0.2% of both Māori and non-Māori ED events were triaged to be seen immediately.
    • 6.3% of Māori ED events were triaged to be seen within 10 minutes compared to 6.7% of non-Māori ED events.
    • A higher proportion of non-Māori ED events were triaged to be seen within 30 minutes compared to Māori (36.6% versus 33.7%).
    • A slightly higher proportion of Māori ED events were triaged to be seen within a longer timeframe compared to non-Māori ED events. i.e. 60 minutes (45.8% versus 44.5%) and 120 minutes (13.9% versus 11.8%).

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

  • The average ED arrival to assessment time for Māori patients was 49 mins compared to 51 mins for non-Māori.
  • The ED LOS (Length of Stay) for Māori patients was 156 mins compared to 178 mins for non-Māori.
  • The ward LOS for Māori patients was 94 hours compared to 119 hours for non-Māori.
  • 12% of Māori patients encountered access block compared to 15% of non-Māori.
  • 0.2% of Māori patients died in ED or within 10 days of ED discharge compared to 0.5% of non-Māori patients.
  • 10% of both Māori and non-Maori 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 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 1.1 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 1.2 times the odds of death for non-Māori patients.
