Abstract
"Nowadays, there are a very large number of patients that need specific health support at home. The deployment of broadband communication networks is making feasible the provision of home care services with a proper quality of service. This paper presents a telehomecare multimedia platform that runs over integrated services digital network and internet protocol using videoconferencing standards H.320 and H.323, and standard TV set for patient interaction. This platform allows online remote monitoring: [electrocardiogram] ECG, heart sound, blood pressure. Usability, affordability, and interoperability were considered for the design and development of its hardware and software components. A first evaluation of technical and usability aspects were carried forward with 52 patients of a private clinic and 10 students in the University. Results show a high rate (mean = 4.33, standard deviation--SD = 1.63 in a five-point Likert scale) in the global perception of users on the quality of images, voice, and feeling of virtual presence."
Objective
To present "a telehomecare multimedia platform that runs over integrated services digital network and internet protocol using videoconferencing standards H.320 and H.323, and standard TV set for patient interaction."
Type Clinic
Primary care and specialty care
Size
unknown
Geography
Urban
Type of Health IT
Telemedicine
Type of Health IT Functions
The system enables "audiovisual contact between the patient and nurse or doctor, and may include vital sign recording and physiological data measurements, such as blood pressure, ECG, spirometry, and others."
Context or other IT in place
The study site had a patient record database management system in place.
Workflow-Related Findings
"Fifty sessions of short duration were performed in Group A, one per patient, assisted by a nurse. Results show the first impression and reaction of patients confronted to a new system. The technical aspects, i.e., video and audio, are rated high (mean 4.54 SD 0.61) and the more subjective aspects such as the feeling of presence and privacy are rated lower (mean 3.78 SD 1.22), which indicates different reactions to a technological device. Nevertheless, the global result is acceptable. In Group B, two patients maintained 16 sessions from home, without external support. The results show a better rate than group A in the feeling of presence and privacy, indicating they got used to the system. On the contrary, technical aspects are rated lower because failures in the connection appeared in three occasions. The global perception is also good." "The global results [for Group C] are similar as for Group A, but for the feeling of virtual presence" is higher.
Study Design
Only postintervention (no control group)
Study Participants
The study participants were split into three groups. Group A consisted of 50 gynecology patients who received one telemonitoring session each. Group B consisted of two pregnant women who received 16 sessions each. Group C consisted of ten students in the University.
