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.
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
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.
