Study for Early Detection of Drug Interactions in Older Hospitalized Patients Using on Line Software

A drug interaction (DI) is the mutual action of two drugs in a way that they can increase their action, even to a toxic level, or reduce it to its minimum. People elder than 65 years old have theirs biological ability to metabolized and eliminate drugs impaired. Even more, they tend to suffer from many diseases, are treated for many physicians, and receive many drugs for those conditions. If hospitalized older people are prone to receive a greater number of drugs. This scenario is the worst to suffer from adverse drug events and DI, which in turn compromise more the health and even life of hospitalized older people. Many computerized strategies have been developed to prevent those problems. In this trial the investigators use on line software to early detect DI that could endanger health or life of hospitalized older patients.
