EXEHDA-TG: uma contribuição à avaliação das metas terapêuticas explorando uma abordagem ubíqua consciente de situação

Abstract

The medication therapy process in the hospital environment is complex and error prone. Best practices have been developed to reduce the occurrence of medication errors by including verifications in the process. The premise is that with the use of technology, it is possible to automate these verifications, reducing the number of medical errors that may occur throughout the cycle of medication treatment. Thus, this work is mainly focused on designing a software architecture aimed to providing the current situation awareness of the patient, called EXEHDA-TG. This architecture will provide monitoring the evolution of the patient’s vital signs, thus allowing the doctor confirm that it is being reached desired effect with the administration of medications. This effect desired by doctors in vital parameters is, in the developed architecture, called Therapeutic Goal. The architecture considers a distributed perspective to acquisition and processing of contextual information. The developed proposal was premised on its integration to a middleware for ubiquitous computing, producing an alternative to meet the demands in the medical field. The TG-EXEHDA automates the acquisition and enables the assessment of vital signs based on the knowledge of medical experts. Alerts are generated based on the patient’s clinical status, considering its situation at a given time interval. Sending alerts provides the use of mobile devices, which seems appropriate for the routine work of health professionals. The evaluation of EXEHDA-TG was performed using three scenarios of use, through which it achieved satisfactory results in the analysis of the evolution of vital signs considering the Therapeutic Goal.
