  • 1. HINZ Public Health Workshop: Evon Currie, General Manager Community & Public Health
  • 2. A slight alteration …
    • From:
    “ How might a PHS contribute to joint DHB/Ministry health goals, targets and aspirations ? ” To: “ How might effective information services enable a PHS to contribute to joint DHB/Ministry health goals, targets and aspirations as well as core regulatory and emergency management requirements ? ”
  • 3. Public health units and services: what do we do ?
    • Promote health and prevent illness and hospitalisation by addressing determinants of health
    • We work in partnership to achieve lasting change.
    • Work takes place at a population and environment level.
    • A wide evidence and accountability base, with a comprehensive and multi-faceted information space.
  • 4. Determinants of Health
    • Promote health and prevent illness and hospitalisation by addressing determinants of health
  • 5.  
  • 6. The Population and Public Health “Information Space” Personal health / facility and service –based patient management
    • Based around personal health records
    • Short time frames
    • Real time / short – term and clearly prescribed inputs and outcomes
    • Line level recording systems with standardised semantic and meta-data structures (for example: ICD codes, HL7 messaging, NHI as unique ID)
    Emergency Management Notified disease Population and Public Health
    • Populations / Communities / Environments
    • Activities characterised by important external linkages and accountabilities at local, regional and national levels
    • A premium upon intra / inter – sectoral collaboration
    • Longer time scales for service delivery and evaluation of outcomes
    • A wide and varying range of service provision / inputs and a correspondingly wide evidence base
    • IS requirements characterised by need to effectively distribute information
    • A smaller range of formally established semantic and meta-data structures, most other activities and outcomes taking place outside those structures – Contextual information important for interpretation of data
    Linkages with “host” DHBs, TLAs, core government , service providers, NGOs , other agencies National surveillance and reporting systems
  • 7. Challenges: Information Systems in the Public Health information space
    • General health sector approach to information systems heavily conditioned by personal health and clinical / facility management requirements.
    • This approach only partially applicable in a public health context.
    • Difference in approach and emphasis can present significant challenges for public health services hosted within, or reliant upon DHB IT/IS infrastructures.
    • Similar challenges presented by nationally based and centralised surveillance and reporting systems.
    • Standardisation at an application-specific level is often presented as both a positive objective in itself, and also as a means of achieving economies of scale. However, unless carefully managed, such an approach can easily override fitness for use.
  • 8. Some principles and ideas for moving forward
    • Business needs drive information systems, not the other way around.
    • Standards and interfaces for interoperability, information exchange and evidence base.
    • Keep line-level data as close as possible to where it is needed.
    • Concentrate upon solutions which derive information from data.
    • Sector capability and flexibility of response is important.
    • It might be that a large amount of additional resource is not required.
    • Don’t make the problems bigger than they need to be.
  • 9. Which leads us on to …..
    • The work streams – case studies which characterise two different facets of public health capability and response.
