GIS technology is being used in the healthcare industry today for patient care and preventative medicine among other things. Hospitals and other organizations, with GIS and big data resources now have the ability to collect geographic information from their patients and study trends in illnesses based on where the patients live now and have lived in the past. By displaying this information on a map it allows healthcare workers to visually see trends in illnesses and predict which communities will most likely to be impacted in the future. In addition, understanding where patients have traveled over time enables healthcare officials to predict where ground zero for viruses might be located and how the diseases may have been spread.
A recent GIS study conducted in China determined the next likely at-risk region for the H7N9 avian flu virus is located in a northern region of Vietnam. They were able to determine this information by mapping previous cases of the flu virus which created a cookie-crumb trail that helped them predict northern Vietnam.
GIS applications like the one in China can be used for a variety of healthcare trends. If hospitals start building databases using patient locations, they would be able to detect trends based on patient geography. This could allow hospitals to stock medical inventory based on predictive analytics, train their staff in advance of diseases, and forecast the number of patients that will be affected.
Not only can GIS help predict future at-risk areas, but GIS applications can also help hospitals reduce expenses and improve patient care. A recent study in Maryland compared the use of life flight helicopters to ambulances. The study determined that in 31% of cases when a life flight was used, an ambulance would have been a better choice. Knowing when an ambulance is a better choice could save a lot of money.
The use of GIS technology and big data analytics in healthcare is an emerging area worth watching. Here are some of the use cases referenced above:
