The days of scrawled doctor's notes are slowly coming to a close. In the United States, 93 percent of hospitals are now using at least some electronic medical records and 2.2 percent have given up paper records completely, according to the consulting firm HIMSS Analytics. The federal government has been pushing for electronic medical records for a decade, arguing that they will improve health care and bring down costs. That is still a matter of debate. Critics charge that the system is hobbled by poorly designed software and that some hospitals are using electronic medical records to bill more for the same services.
