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

  • Year

    • ED events per year have increased over time for both Māori (11.8% to 15.6%, 2006-2012) and non-Māori (12.4% to 15.6%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was similar for Māori (49.3% males and 50.7% females) and non-Māori (50.3% males and 49.7% 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 (17.9% versus 8.8%) and 15-24 years (19.2% versus 13.2%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly in the 65-74 age group (10.4% versus 5.3%) and those aged ≥75 (19.2% versus 3.3%).
  • NZDep06
    • 79.5% of all Māori ED events were from the 3 most deprived deciles compared to 51.2% of non-Māori ED events.
    • The highest proportion of Māori ED events were from decile 10 (38.6%) and the highest proportion of non-Māori ED events were from decile 8 (20.6%).
    • The lowest proportion of Māori and non-Māori ED events were from decile 1 (0.7% versus 3.8%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 73.3% of Māori ED events arrived via self-presentation compared to 61.6% of non-Māori ED events.
    • In comparison, non-Māori had a much higher proportion of arrival into ED via ambulance, police and helicopter compared to Māori (37.4% versus 24.4%).
  • Referral type
    • 20.7% of Māori ED events were referred via a general practitioner compared to 24.5% of non-Māori.
    • 5.4% of Māori ED events were via hospital transfer compared to 4.4% of non-Māori ED events.
    • 65.1% of Māori ED events were through self-referral compared to 57.6% of non-Māori ED events.
  • Triage category
    • 1.0% of Māori ED events were triaged to be seen immediately compared to 0.8% of non-Māori ED events.
    • 8.5% of Māori ED events were triaged to be seen within 10 minutes compared to 9.4% of non-Māori ED events.
    • A higher proportion of non-Māori ED events were triaged to be seen within 30 minutes compared to Māori (36.3% versus 33.4%).
    • A 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 (43.5% versus 42.7%) and 120 minutes (13.6% versus 10.8%).

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

  •  The average ED arrival to assessment time for both Māori and non-Māori patients was 53 mins.
  • The ED LOS (Length of Stay) for Māori patients was 188 mins compared to 217 mins for non-Māori.
  • The ward LOS for Māori patients was 73 hours compared to 92 hours for non-Māori.
  • 9% of Māori patients encountered access block compared to 13% of non-Māori.
  • 0.5% 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 1.1 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 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 1.6 times the odds of death for non-Māori patients.
