Health Informatics: Improving Patient-Centered Healthcare Pathway

摘要

Nowadays the use of information and communication technology is becoming prevalent in many aspects of healthcare services from patient registration,to consultation,treatment and pathology tests request. Manual interface techniques have dominated data-capture activities in primary care and secondary care settings for decades. Despites the improvements made in IT,usability issues still remain over the use of I/O devices like the computer keyboard,touch-sensitive screens,light pen and barcodes. Furthermore,clinicians have to use several computer applications when providing healthcare services to patients. One of the problems faced by medical professionals is the lack of data integrity between the different software applications which in turn can hinder the provision of healthcare services tailored to the needs of the patients. The use of digital pen and paper technology integrated with legacy medical systems hold the promise of improving healthcare quality. This paper discusses the issue of data integrity in e-health systems and proposes the modelling of "Smart Forms" via semiotics to potentially improve integrity between legacy systems,making the work of medical professionals easier and improve the quality of care in primary care practices and hospitals.
