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

  • Year

    • ED events per year have increased over time for both Māori (11.3% to 14.2%, 2006-2012) and non-Māori (12.3% to 14.6%, 2006-2012).

  • Gender
    • The gender profile associated with all ED events was different for Māori (51.7% males and 48.3% females) and non-Māori (54.6% males and 45.4% females).
  • Age

    • A higher proportion of Māori ED events were seen in the younger age groups, compared to non-Māori, particularly those aged 0-4years (15.4% versus 7.1%) and 15-24 years (21.1% versus 16.3%). In comparison, a higher proportion of non-Māori ED events were seen in the older age groups, particularly those aged ≥75 (14.8% versus 3.7%).

  • NZDep06
    • 82.7% of all Māori ED events were from the 3 most deprived deciles compared to 57.1% of non-Māori ED events.
    • The highest proportion of Māori ED events were from decile 10 (46.3%) and the highest proportion of non-Māori ED events were from decile 9 (37.0%).
    • The lowest proportion of Māori ED events were from deciles 1 and 3 (0.2%) and the lowest proportion of non-Māori ED events were from decile 3 (0.7%).

Characteristics of presentation (all ED events data).

  • Arrival mode
    • 73.6% of Māori ED events arrived via self-presentation compared to 67.2% of non-Māori ED events.
    • Non-Māori had a higher proportion of arrival into ED via ambulance, police and helicopter compared to Māori (9.6% versus 7.6%).
  • Referral type
    • 15.7% of Māori ED events were via a general practitioner compared to 18.7% of non-Māori.
    • 0.3% of Māori ED events were via hospital transfer compared to 0.2% of non-Māori ED events.
    •  67.1% of Māori ED events were through self-referral compared to 59.8% of non-Māori.
  • Triage category
    • 0.4% of both Māori and non-Māori ED events were triaged to be seen immediately.
    • Māori and non-Māori had very similar proportions of ED events triaged to be seen within 10 minutes (5.1% versus 5.3%), 30 minutes (20.4% versus 20.1%), 60 minutes (32.7% versus 32.4%) and 120 minutes (41.3% versus 41.8%).

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 37 minutes.
  • The ED LOS (Length of Stay) for Māori patients was 174 mins compared to 176 mins for non-Māori.
  • The ward LOS for Māori patients was 75 hours compared to 89 hours for non-Māori.
  • 2% of both Māori and non-Māori patients encountered access block.
  • 0.4% of Māori patients died in ED or within 10 days of ED discharge compared to 0.7% 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 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 1.0 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.
