　　UPMC's early attempts to create a universal EHR system, such as its ambulatory electronic medical records rolled out between 2000 and 2005, were met with resistance as doctors, staff and other users either avoided using the new technology altogether or clung to individual, disconnected software and systems that UPMC's IT department had implemented over the years.

　　On the mend

　　Although UPMC began digitizing some of its records in 1996, the turning point in its efforts came in 2004 with the rollout of its eRecord system across the entire health care network. eRecord now contains more than 3.6 million electronic patient records, including images and CT scans, clinical laboratory information, radiology data, and a picture archival and communication system that digitizes images and makes them available on PCs. The EHR system has 29,000 users, including more than 5,000 physicians employed by or affiliated with UPMC.

　　If UPMC makes EHR systems look easy, don't be fooled, cautions UPMC chief medical information officer Dan Martich, who says the health care network's IT systems require a "huge, ongoing effort" to ensure that those systems can communicate with one another. One of the main reasons is that UPMC, like many other health care organizations, uses a number of different vendors for its medical and IT systems, leaving the integration largely up to the IT staff.

　　Since doctors typically do not want to change the way they work for the sake of a computer system, the success of an EHR program is dictated not only by the presence of the technology but also by how well the doctors are trained on, and use, the technology. Physicians need to see the benefits of using EHR systems both persistently and consistently, says Louis Baverso, chief information officer at UPMC's Magee-Women's Hospital. But these benefits might not be obvious at first, he says, adding, "What doctors see in the beginning is that they're losing their ability to work with paper documents, which has been so valuable to them up until now."

　　Opportunities and costs

　　Given the lack of EHR adoption throughout the health care world, there are a lot of opportunities to get this right (or wrong). Less than 10 percent of U.S. hospitals have adopted electronic medical records even in the most basic way, according to a study authored by Ashish Jha, associate professor of health policy and management at Harvard School of Public Health. Only 1.5 percent have adopted a comprehensive system of electronic records that includes physicians' notes and orders and decision support systems that alert doctors of potential drug interactions or other problems that might result from their intended orders.

　　Cost is the primary factor stalling EHR systems, followed by resistance from physicians unwilling to adopt new technologies and a lack of staff with adequate IT expertise, according to Jha. He indicated that a hospital could spend from $20 million to $200 million to implement an electronic record system over several years, depending on the size of the hospital. A typical doctor's office would cost an estimated $50,000 to outfit with an EHR system.

　　The upside of EHR systems is more difficult to quantify. Although some estimates say that hospitals and doctor's offices could save as much as $100 million annually by moving to EHRs, the mere act of implementing the technology guarantees neither cost savings nor improvements in care, Jha said during a Harvard School of Public Health community forum on September 17. Another Harvard study of hospital computerization likewise determined that cutting costs and improving care through health IT as it exists today is "wishful thinking". This study was led by David Himmelstein, associate professor at Harvard Medical School.

　　The cost of getting it wrong

　　The difference between the projected cost savings and the reality of the situation stems from the fact that the EHR technologies implemented to date have not been designed to save money or improve patient care, says Leonard D'Avolio, associate center director of Biomedical Informatics at the Massachusetts Veterans Epidemiology Research and Information Center (MAVERIC). Instead, EHRs are used to document individual patients' conditions, pass this information among clinicians treating those patients, justify financial reimbursement and serve as the legal records of events.
