Acute demand – what does it look like?
ED
Some increase: but national ED data prior to 2009/10 not as robust as inpatient data
Acute inpatient (excludes short stay admissions <24 hours, electives, and mental health admissions)
2000-2009: increase from 323,000 to 371,000 pa - 2/3 in Auckland.
A 15% increase, but only 2.4% greater than the increase in population.

ED attenders & admission:
• strong association with age – the elderly
• weaker association with ethnicity and deprivation
ED attenders not admitted:
• people from deprivation quintile 4&5 = 40% of the population yet 55% of non-admitted patients
DHB factors are significant
• smaller DHBs have a higher proportion of ED attenders not admitted

Community
services
ED Inpatient Community
• Primary Care (distribution & availability – inc after hours)• Changing GP practice• Poor access to diagnostics and specialist opinions• Changing referral patterns (variability++)• variable attachment with general practice• Financial barriers• Changing use of ambulances• Fragmentation of services
• Improved ED services & facilities• Changing (& variable) admission thresholds• Inpatient bed availability• Repeat attenders• Local behaviours
• Bed availability• Advances in medical technology• Discharge planning
• Family & community support• Relationship with primary care• Primary care capability & capacity• Aged residential care capability & capacity
Patients – changing:
demographics – two broad segments – young adult & elderly
morbidity – more chronic illness
expectations – more “consumerism” + a “medicalised” population
more self-referral, but people confused about where to go

And it depends on the problem definition
Growth• reducing our overall growth rate requires a focus on metropolitan Auckland
Variation between DHBs presents a significant improvement opportunity. Addressing this will require• good comparative data• clinical engagement• an understanding of local initiatives/patterns of behaviour/admission thresholds• a whole of system approach - ? the DHB funder role
Its complex - there’s no “silver bullet”

What works
Kings Fund Seminar
• Proactive management of people with long term conditions, especially people with multiple conditions• Integrated working between health and social care• Multiple coordinated strategies, underpinned by an integrated information system• Use of advance directives and a range of alternatives to hospital eg hospice• Preventing re-admissions – active management of transitions• The use of “virtual” wards in the community• The use of practice based commissioning enabling integration between general practices and other services• A single assessment and coordinated care approach for older people at risk of hospital admission
