Essentially all hospitals and clinics depend on computers for administrative and financial procedures and for providing access to clinical data. Most physicians have been exposed to the powerful available systems for searching the biomedical literature by computer. Modern medical imaging techniques depend on computers for image generation, small computers have become mandatory elements in the research laboratory, and information systems are becoming vital topics for medical education. The clinical community has long anticipated the day when computers would be able to assist with diagnosis and with making decisions about patient treatment. One way to decide if the advantages of computers and mobile phones in medicine overcome the disadvantages to show physicians computer applications that may be useful to them.
