  1. Driving Distance to Telemedicine Sites in Northern Ontario as a Measure of Potential Access to Healthcare Laurel O’Gorman, MA John C. Hogenbirk, MSc

  2. Conflict of Interest Declaration: Nothing to Disclose Presenter: Laurel O’Gorman Title of Presentation: Driving distance to telemedicine in Northern Ontario as a measure of potential access to healthcare I have no financial or personal relationships to disclose

  3. Rationale • To determine if the location of Ontario Telemedicine Network (OTN) sites can help improve access to medical care in underserved communities in Ontario • Measuring highest possible potential for access • Research funded by the MOHLTC’s Health Systems Research Fund

  4. Ontario Telemedicine Network (OTN) • Not-for-profit organization funded by the Ontario Ministry of Health and Long Term Care (MOHLTC) • Enables access to medical care services by using technology to connect patients to physicians throughout Ontario. • OTN is the largest telemedicine service provider in Canada (Coach, 2013) and one of the largest in the world (Holmes, 2009). (OTN, 2012)

  5. Methods • Travel time by private vehicle from center of each community to the nearest OTN site calculated using posted speed limits and road distance. • ArcGIS 10.0 Network Analyst extension • MNR Cultural Points data • DMTI Ontario Road data • OTN Site locations from OTN • Pearson’s Chi-squared test to determine if there were differences in travel time among community population group or between rural and urban communities.

  6. OTN Sites by Rurality

  7. Driving Distance to OTN Sites for Northern Ontario Communities

  8. Driving Distance to OTN Sites for Northern Ontario Communities (by Population Group)

  9. Driving Distance to OTN Sites for Northern Ontario Communities (by Rurality)

  10. Summary of Findings • All communities with populations over 10,000 and 97% of communities with populations over 1,000 are within 1 hour of an OTN Site • For communities with populations under 50, 83% are within 1 hour of an OTN site • All urban communities are within 1 hour of an OTN site, compared with 84% of rural communities.

  11. Discussion • Proximity ≠ Access • Theoretical measure of maximum potential access • Other considerations • Number of sites within a given community • Site location (organization, privacy, hours) • Support / referrals from health care providers • Weather

  12. Next Steps and Concluding Remarks • Measuring actual OTN utilization throughout Ontario • Looking at factors associated with high and low use • Qualitative interviews on OTN use in Northern Ontario • Policy recommendations regarding the (1) use of and (2) modality of virtual care for health service delivery in the north, especially in rural and remote areas

  13. Acknowledgements We would like to thank OTN for site data and Tomasz Mrozewski and Jill Sherman for locating map data. This research was supported by the Ontario Ministry of Health and Long Term Care’s Health System Research Fund (Grant 04254SB).
