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

  • Year

    • ED events per year have increased over time for both Māori (12.9% to 15.9%, 2006-2012) and non-Māori (12.2% to 16.5%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was similar for Māori (47.1% males and 52.9% females) and non-Māori (50.8% males and 49.2% 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 (19.6% versus 15.1%) and 15-24 years (19.9% versus 13.5%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly in the ≥75 age group (11.9% versus 2.3%).
  • NZDep06
    • 82.4% of all Māori ED events were from the 3 most deprived deciles compared to 64.1% of non-Māori ED events.
    • The highest proportion of ED events for both Māori and non-Māori were from decile 10 (43.4% versus 31.5%).
    • The lowest proportion of Māori ED events were from decile 1 (0.8%) and the lowest proportion of non-Māori ED events were from decile 7 (2.7%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 59.8% of Māori ED events arrived via self-presentation compared to 55.6% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, helicopter and police compared to Māori (29.7% versus 25.5%).
  • Referral type
    • Both Māori and non-Māori had a similar proportion of hospital transfers to ED (1.3% versus 1.5%).
    • 69.6% of Māori ED events were via self-referral compared to 66.8% of non-Māori.
  • Triage category
    • 1.0% of Māori ED events were triaged to be seen immediately compared to 0.9% of non-Māori ED events.
    • 11.0% of Māori ED events were triaged to be seen within 10 minutes compared to 12.7% of non-Māori ED events.
    • Māori and non-Māori had very similar proportions of ED events triaged to be seen within 30 minutes (44.6% versus 43.6%), 60 minutes (40.1% versus 39.8%) and 120 minutes (3.2% versus 3.0%).

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

  •  The average ED arrival to assessment time for Māori patients was 76 mins compared to 78 mins for non-Māori.
  • The ED LOS (Length of Stay) for Māori patients was 339 mins compared to 387 mins for non-Māori.
  • The ward LOS for Māori patients was 79 hours compared to 85 hours for non-Māori.
  • 23% of Māori patients encountered access block compared to 26% of non-Māori.
  • 0.4% of Māori patients died in ED or within 10 days of ED discharge compared to 0.6% of non-Māori patients.
  • 4% of both Māori and non-Māori patients re-presented at ED within 72 hours of ED/ward discharge.
  • 3% of Māori patients had a hospital readmission within 72 hours of ED/ward discharge compared to 4% of non-Māori patients.

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 0.9 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 1.3 times the odds of death for non-Māori patients.
