Computers are primarily used for medical education and clinical care. Computers are an excellent source for storing patient data and history. They also allow users to access important information much more quickly. Centuries ago, people didn't have computers. Instead, they had to write everything by hand. When writing down the information, doctors easily lost important patient histories. Now, with computers, doctors can enter information and the data is easily stored. The data is also much easier to find. Doctors don't need to go looking for it everywhere, they can just type in what they are looking for and the result is there. Due to most doctors' busy schedules, they are not able to see every patient who needs their help, but they can collaborate better with a patient over the Internet. People can email their doctor if they experience certain complications. Patients and doctors can exchange information and resolve problems more quickly. Thanks to the efficiency of computer network technology, communication between people has become much faster. Research shows that in recent years, computers and PDAs have been most widely used for patient education and assistance. Rowe et al. conducted a study on computer use across Canada and concluded that 38% of candidates responded that they owned a computer and 13% of candidates were "very" comfortable using computers . Then, in 1998, Jerant et al. surveyed first-year medical students and junior residents and found much higher rates of computer ownership: 91% of faculty, 86% of students, and 79% of residents. The survey also concluded that older people did not have the same skills and were not as confident in computers as in the middle of paper......
