Computer Science and Healthcare

Incredible advances have been made in health care in the last few decades. Many of these have relied upon computer technology or were brought about by applying computer science capabilities to medical problems. Mapping the human genome was only possible because of algorithms developed by computer scientists. Image processing and pattern recognition technology now commonly evaluate radiology scans, and electronic medical records and physician ordering systems are now coming on-line, reducing medical errors and improving the quality of care. Microscopic surgery is done using robots, improving the precision of the procedure and thus improving the outcomes and reducing recovery time. On-line diagnostics systems help physicians isolate the possible causes for a patient's symptoms and propose treatment plans.


The list of what has been accomplished is astounding, but even more outstanding advances are expected in the future, building upon computer science technology that is currently being developed. For example, information retrieval and data mining should provide improved methods for early detection of disease outbreaks and unsuspected drug reactions. Personalized medicine will provide treatment plans, not based on statistical outcomes for large populations, but on the individual's DNA. Telemedicine will support medical examinations in remote areas of the world and provide up to date diagnostic support. Computer assistive devices will allow the disabled or elderly to lead fuller, more independent lives.

Just about all areas of computing are making significant contributions to health care. Computer scientists can also work directly in Medical Informatics, or they can combine computer science with other majors such as biology, communications disorders, and public health.
