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

  • Year

    • ED events per year have increased over time for both Māori (12.9% to 15.4%, 2006-2012) and non-Māori (13.1% to 15.4%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was similar for Māori (51.8% males and 48.2% females) and non-Māori (51.0% males and 49.0% 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 (18.2% versus 8.1%) and 15-24 years (22.0% versus 16.6%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly in the 65-74 age group (10.0% versus 4.5%) and those aged ≥75 (18.1% versus 2.9%).

  • NZDep06
    • 63.0% of all Māori ED events were from the 3 most deprived deciles compared to 50.2% of non-Māori ED events.
    • The highest proportion of both Māori and non-Māori ED events were from decile 9 (28.6% versus 22.7%).
    • The lowest proportion of Māori ED events were from decile 1 (1.3%) and the lowest proportion of non-Māori ED events were from decile 3 (2.8%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 73.1% of Māori ED events arrived via self-presentation compared to 66.6% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, police and helicopter compared to Māori (33.4% versus 26.9%).
  • Referral type
    • 14.0% of Māori ED events were referred via a general practitioner compared to 17.0% of non-Māori.
    • 84.7% of Māori ED events were through self-referral compared to 81.6% of non-Māori.
  • Triage category
    • 0.4% of both Māori and non-Māori ED events were triaged to be seen immediately.
    • 8.1% of Māori ED events were triaged to be seen within 10 minutes compared to 8.5% of non-Māori ED events.
    • 47.2% of Māori ED events were triaged to be seen within 30 minutes compared to 49.4% of non-Māori ED events.
    • 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 (38.4% versus 36.8%) and 120 minutes (5.3% versus 4.7%).

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

  • The average ED arrival to assessment time for Māori patients was 80 mins compared to 77 mins for non-Māori.
  • The ED LOS (Length of Stay) for Māori patients was 218 mins compared to 244 mins for non-Māori.
  • The ward LOS for Māori patients was 85 hours compared to 124 hours for non-Māori.
  • 12% of Māori patients encountered access block compared to 18% of non-Māori.
  • 0.3% of Māori patients died in ED or within 10 days of ED discharge compared to 0.8% of non-Māori patients.
  • 6% 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 1.0 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 1.1 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 1.5 times the odds of death for non-Māori patients.
