  1. Social Determinants of Health in Health Care Planning Dr Danielle Butler Robert Graham Centre/Australian Primary Health Care Research Institute Visiting Fellowship 2009

  2. Acknowledgements  APHCRI  Support, guidance and time from Robert Graham Staff The research in this presentation is a project of the Australian Primary Health Care Research Institute, which is supported by a grant from the Australian Government Department of Health and Ageing, under the Primary Health Care Research, Evaluation and Development Strategy. The information and opinions containing in it do not necessarily reflect the view or policy of the APHCRI or the Australian Government Department of Health and Ageing

  3. Background and Policy Context  Increasing health and health care access inequity across social gradients between and within countries  Need for some measure of this in health planning and resource allocation  Australian Health reform  Access and equity  Primary health care/preventative care  Data collection/dissemination/monitoring

  4. Small area measures of social deprivation  Captures personal and contextual components  UK, NZ, Aust/US  Domains  Employment, income, social capital, education/skills, barriers to housing and services  Use in primary care policy and public health  Inherent premise: social deprivation predicts poor health outcomes and health care access. Targeting services to these areas will improve inequity  Incentives/funding, benchmarking, public health monitoring  Limitations:  Ecological fallacy, populations do not always behave as determined by administrative boundaries

  5. Determining need in Australia Current Strategies  Workforce shortage and maldistribution a significant concern  Current workforce distribution programs based on geographical definitions only (RA)  Complex and generous  Shortage areas for IMGs only  Outer metro for GP trainees

  6. Determining need in Australia The Evidence  Utilisation and access to primary health care services relates to:  Rurality, age, socioeconomic deprivation, indigenous status and health outcomes  Inequity exists along social and remoteness gradients  Rural access index for Victoria ( McGrail and Humphreys, 2009)  Includes measures of GP supply, geographical distance, mobility, health need and socioeconomic disadvantage  Significant heterogeneity within remoteness areas  Reliance of geographical definitions alone fails to recognise the diversity of need and inequity of access within areas

  7. GIS and Health in Australia  Use of spatial relationships and maps – a powerful tool for understanding health care service issues  Enhances understanding of community health needs  Immediate visualisation of solutions  A common platform for discussion between stakeholders- academia, policy and decision makers, clinician and community  Public health information development unit (PHIDU)  Practice Health Atlas  Rural Access Index  HealthLandscape: created an Australian health mapping tool through collaborative fellowship

  14. Access/Health need score for Australia  Constructed score  Physician score 1-5  Value of 5 =1:1282-no physicians  Rural score 1-5  Disadvantage score 1-5  Combine 3-15  Assumed equal weighting  Factor analysis confirmed this assumption  Relationship likely more complex than this  requires further investigation  validation

  16. Summary  Health and health care access vary along social gradients  Small area measures of socioeconomic deprivation used internationally  This study has created a national composite measure of deprivation predictive of health outcomes and health risk behaviours  Can be mapped to enable visualisation of need and hence target resources where needed most  Adds to the growing body of evidence of the valuable role of GIS in primary health care research, policy and planning
