RESUMO
The Patient Location Tracking Query (PLQ) is the IHE integration profile in order to find the location of patient only in a hospital, not for cross-referencing between multiple hospitals. In Japan, it is common for elderly patients to consult multiple departments in one hospital visit. To find the location of patients quickly is very important for productivity and use of resources in a hospital. We analyzed the workflow of patients and defined three actors and two transactions for PLQ integration profile. In order to collect the location of patients, multiple systems must provide the location into central management system. We proposed PLQ for the better patient care in hospitals. We believe that by using this PLQ profile hospital staffs are able to utilize the resource more efficiently.
