How Can Information Technology Improve Health Care Quality?

The health care sector has languished behind almost all other industries in adopting information technology, which has the potential of vastly improving quality. For example, a variety of studies have found that prescribing drugs through a system known as computer physician order entry, compared with a handwritten prescription, greatly reduces the incidence of the wrong medication being prescribed or the wrong dose dispensed. There are significant barriers to the adoption of information technologies in health care. These barriers include technical and infrastructure obstacles, initial implementation costs, provider resistance, current reimbursement structures and a lack of more uniform standards that would allow products from different vendors to work together.
