## [16] "Page.13: Therefore we combine TAM variables, perceived output quality fromTAM2 and two additional constructs, perceived  cost-effectiveness  and  trust,  to  form  the  new  model.  The  new  relationships  postulated  are  trust  influences  perceived  usefulness,  perceived  output  quality  influences  perceived  cost-effectiveness,  perceived  cost-effectiveness  influences  attitude toward using, and perceived cost-effectiveness influences intention to use the system.  Trust to perceived usefulness: we envisage that when the system is perceived as trustworthy and the patients have  confidence in the system then they will consider it as useful.  Perceived output quality to perceived cost-effectiveness: when the quality of the system is high, it is expected that  the  cost  will  reduce,  in  other  words  the  system  will  be  cost-effective.  For  instance,  when  the  hospitalization  rate  is  reduced, the cost related to the care will also be reduced.  Perceived cost-effectiveness to attitude toward using: if the users believe that the system reduces cost of their care,  their attitude toward using it will be positive.  Perceived cost-effectiveness to intention to use: the intention of the patients to use the system will be high if they  realize that using it will reduce the cost related to their care.  "
