@the above questions: I am researching the field of health informatics, and just got accepted to Waterloo University (Canadian University- I live in Canada) for their Master of Health Informatics program.
From what I've read from several sources, it seems as if Health Informatics is a rapidly growing field of interest for many people, and therefore, many programs are being offered online now, so there are likely many other universities that offer a similar program.
Since it's a Masters program, there are conditions to meet the eligibility criteria, like holding an undergraduate four year degree in a health or health related profession and having completed some work experience in a healthcare setting.
In my case, I have an undergrad in social work, and worked in a hospital for two years, so this seemed to meet the criteria for Waterloo U. There are also undergraduate degrees in Health Informatics, but I haven't come across any of those that are offered completely online as of yet.
I think the field "Health Informatics" includes jobs/titles like "health information technician" and "health information analysts" etc. but not entirely sure. In Waterloo's Masters program, there are two streams you can enter into within the program. They are computer science and public health, so I suppose certain jobs within the field call for more of a computer science or engineering focused person which would be more suitable for a really "techie" job like software development and the actual designing of programs.
On the other hand, a public health focused person might be better suited to the research and networking jobs to help gather the information needed to determine the needs of an organization, etc. I am still trying to find out more!
