Barriers and Challenges : Barriers and Challenges Rural geography
Many locations not owned by health authority
Massive miles traveled with multiple rural bases
Lack of infrastructure and resources for IT
Local IT up to network challenge in urban center, not multiple rural sites
Lack of funding and resources
Freeze on funding initiatives dependent on provincial government.
Lack of human resources in most professions.
Lack of telecommunication lines
Lack of community network lines used to secure privacy.
Reluctant user buy-in
Solutions : Solutions Meet rural challenges through use of wireless internets and development of VPN tunnels for data security
Increase centralized funding from HISC and province for targeted initiatives.
Coordinate local training with opportunity to practice away from work and buddy system to ensure inter-user reliability once implemented.
Change process considerations for impact on end-user.
Solutions : Solutions “…a comprehensive care system that supports the distributed care team..(and)..allow them to share key observations linked to results of diagnostic tests, data entered by the patient/client themselves, and sophisticated decision support tools” J. Smith 2003
Manitoba Go Bombers! : Manitoba Go Bombers!
EHR Brief history : EHR Brief history Many of the hospitals in the province had their own computer system and technical support. Recognizing building disparate systems on different platforms was counter productive, Manitoba formed e-Health in June 2006 to provide support and solutions that will lead to a province wide EHR within three to five years
(Canadian Medical Association, 2007).
Goal of e-Health : Goal of e-Health The province approved $150 Million to implement an EPR over the next three to five years.
The goal is to have every patient’s current medical information including test results and prescriptions immediately accessible online to authorized caregivers in hospitals and clinics in the province, 24/7 ( Canadian Medical Association, 2007).

Example Project : Example Project The Primary Data Center (PDC) provides a centralized location where all regional applications and programs can securely reside for the Manitoba eHealth Provincial Program (formerly e-Health Services, a division of the WRHA). The PDC is capable of functioning 24 hours a day, seven days a week, eliminating data outages due to unfavorable weather, physical violations, construction mishaps and equipment failure (WRHA, 2006).
Example Project (cont’d) : Example Project (cont’d) The PDC is one of the most secure data centres in the country. The facility is only second in the country, in terms of security, to the facility used by the Canadian Security Intelligence Service (CSIS) in Ottawa. The facility created for the e-Health Provincial Program has met all the requirements to call itself a Tier III Data Center. This includes at least 20 major mechanical, electrical, fire protection, security and other systems requirements. By December 2007 the PDC will be classified as a Tier IV data center, the highest rating available. (WRHA, 2006)
Barriers : Barriers Current computer systems do not have the capacity to support the network required for an additional 8,000 RN’s, LPN’S, RPN’s, as well as, an additional 200 allied health professionals. (WRHA, 2007)
As many as 4,000 health care professionals within the WRHA do not have access to e-mail.
Barriers : Barriers Understanding and addressing the culture shift in how nurse’s communicate. “Historical model of paper documentation” (Kirkley & Stein, 2004).
Worker resistance: The older the generation, the more resistance there is. (Kirkley & Stein, 2004).
The average age of the nurse practicing in Manitoba is 54 (CRNM, 2004).
Barriers : Barriers Funding- for hiring IT personnel, building networks, developing education packages and scheduling education sessions to help prepare the workforce for computerization
Implementation Challenges : Implementation Challenges Lab Pharmacy Diagnostic Imaging
Implementation Challenges : Implementation Challenges Interfacing new technology with existing systems- some existing systems are too old, others have no system in place at all, e.g., Pharmacy, Lab, Diagnostic Imaging (DI).
Equipment and location-how will nursing and allied health use EHR ? A variety of devices should be available, some people will want to sit, others will prefer a laptop, others will prefer a notebook. (Kirkley & Stein, 2004)
Staff preparation and training
Implementation Challenges : Implementation Challenges Physician engagement
A review by the Canadian Medical Association (CMA), revealed there is limited physician involvement in advancing the e-health agenda, there is no articulation of the physician role in the EPR’s creation. Some provinces have established a structured approach to working with physicians and instituted IT programs to support the automation of physicians’ offices, Manitoba has not. ( CMA, 2007).
Implementation Challenges : Implementation Challenges Physician office automation
The focus of e-health has been building large applications for drug information, laboratories, diagnostic imaging and telehealth. Currently, there is not a province wide initiative to automate physicians’ offices. Connectivity to these offices are crucial to ensure all points of care are captured. (CMA, 2007)
Solutions : Solutions Hospitals throughout the province that have not joined the Regional Health Authorities need to commit soon to avoid delays in e-health and provincial projects
Budgets increased to allow for training of staff and leasing of computer equipment
Form committees at each site comprised of various disciplines to discuss projects and help devise implementation strategies
Promote EHR to staff as a positive change that will improve patient care
