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

  • Year

    • ED events per year have increased over time for both Māori (10.5% to 17.5%, 2006-2012) and non-Māori (11.5% to 15.9%, 2006-2012).

  • 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 (14.5% versus 6.6%) and 15-24 years (25.0% versus 16.3%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly in the 55-64 age group (10.4% versus 5.4%), 65-74 age group (9.3% versus 3.5%) and those aged ≥75 (14.1% versus 1.9%).

  • NZDep06
    • 41.0% of all Māori ED events were from the 3 most deprived deciles compared to 26.8% of non-Māori ED events.
    • The highest proportion of Māori and non-Māori ED events were from decile 8 (29.1% versus 19.9%).
    • The lowest proportion of Māori and non-Māori ED events were from decile 10 (0.9% versus 0.2%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 81.9% of Māori ED events arrived via self-presentation compared to 76.6% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, police and helicopter compared to Māori (20.9% versus 15.3%)
  • Referral type
    • 10.8% of Māori ED events were referred via a general practitioner compared to 13.7% of non-Māori.
    • Māori ED events had a higher proportion of self-referral compared to non-Māori (69.8% versus 62.2%).
  • Triage category
    • 0.3% of both Māori and non-Māori ED events were triaged to be seen immediately.
    • 7.3% of Māori ED events were triaged to be seen within 10 minutes compared to 8.6% of non-Māori ED events.
    • 37.3% of Māori ED events were triaged to be seen within 30 minutes compared to 37.9% of non-Māori.
    • A higher proportion of Māori ED events were triaged to be seen within 60 minutes compared to non-Māori (42.1% versus 39.8%).
    • 13.0% of Māori ED events were triaged to be seen within 120 minutes compared to 13.4% of non-Māori ED events.

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 34 mins
  • The ED LOS (Length of Stay) for Māori patients was 100 mins compared to 109 mins for non-Māori.
  • The ward LOS for Māori patients was 57 hours compared to 90 hours for non-Māori.
  • 2% of both Māori and non-Māori patients encountered access block.
  • 0.3% of Māori patients died in ED or within 10 days of ED discharge compared to 0.6% of non-Māori patients.
  • 9% 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 1.4 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 1.9 times the odds of death for non-Māori patients.
