Market Validation: Main results
The target was to test the HealthService24 system in real-life scenarios, assessing the feasibility for integration in the clinical process and market viability. Another target was the validation of the system and its services from the medical and health-economic point of view. Below follows an overview of the results per main criteria.
The Executive Summary (4 p.) provides an overview of the results per pilot site
End-user social evaluation
- High satisfaction
Professionals satisfaction related to access to patient condition from anywhere,
anytime, any location. In addition, the low training effort was appreciated.
Patients felt more reassured that they were given a higher level of care and felt more empowered. E.g. patient could pin point the time that he felt any symptoms using the system, lead to the comprehension that the patient could play a more vital role in his health care supervision
- Convenience of use
- No disruption with current work practices
- Easy to apply / extend to other areas
Technical evaluation of the HS24 research system
As a result of the pilots’ feedback, the prototype of the HS24 research system was continuously improved over time. University of Twente even released a second version of their system. The overall technical evaluation included the following comments, valid for all trial sites.
HS24v2.0R good successor of v1.0R
Helpful warning and error messages guided users
The user interface was improved, now much better to use; MBU interface very user-friendly and users were easily trained to use it
Connection screen has indicators for critical resources (e.g. GPRS signal strength, battery level of BAN components)
HS24 2.0.1R stability depends on native PDA OS (e.g. MS WM2003)
In poor signal’s GPRS strength conditions the HS24 BAN may stop transmitting data to the BackEnd server (e.g. residing at the mHealth call centre) due to MBU resource starvation.
Battery capacity of MBU (i.e. PDA) limits BAN operational time to 3-6hrs (cont. monitoring)
Bulky BAN system components (i.e. sensor system and PDA) and long sensor wires limit wearabilty.
MST trial revealed GPRS (i.e. GSM) interference when MBU or other transmitting GSM device operates in close proximity of TMSi Mobi4 sensor system.
The Portilab program (Used for visualisation and analysis of physiological data) displayed the measurements correctly and accurately but in some cases, when it was not closed properly, it became unusable and we had to restore it from our backup server
Health economics evaluation
Clinical evaluation
The mobile health monitoring services tested (combining the technological solution for vital signs monitoring and the clinical and educational intervention) have proved to have a positive clinical impact.
- Patients had a better knowledge of the disease
- Lower rate in unexpected patient admissions observed
- Higher rate of early discharge observed because patients using the system felt more reassured that they were ok
