A comprehensive evaluation should include the intellect elements of HIT use. This paper proposes a task-fit measure of HIT that integrates an information/knowledge quality scale into a validated judicious HIT use measure. It also presents some statistics that have implications for policy-making and curriculum development.Methods: Statistical analyses were performed on a subset of survey data. A structural equation modelling technique was applied to examine the associations among intent to use HIT, professional concerns and information/knowledge quality.Results: The statistical results show that altruism, autonomy, physician-patient relationship, (subconscious) autonomy, digestible information and medical history associate with each other to different extents. Only altruism and medical history show to be significant de...

Two sources of uncertainty are introduced. One source arises as, based on the patient's "apparent" symptoms, only a priori estimates of the likelihood of alternative medical conditions can be inferred. They can be improved upon by a diagnostic test, but inherent in such tests is the possibility of a "false positive". This second source of uncertainty is shown to be critical in the possible over- or undersupply of medical treatment. Remedial pricing structures are suggested.

Surprisingly, a simple and quantifiable model of KM representation strategy does not seem to exist. This paper applies economics principles to derive a model for thinking of the decision problem in quantitative terms. The decision is about choosing the right codification-personalization split where all knowledge related resources are efficiently allocated to simultaneously support the business process or production. It shows that failing at making a diversified resource choice may conclude a suboptimal strategy (split). It seems to justify the propositions of an oft-cited paper and some published evidence. That is, a 50-50 split or a merely pure strategy can also be the optimal strategy. The model can be extended to include subjective decision factor, and be mastered easily. In future research, it may be developed into a game theoretical framework to capture the strategic and/or cooperative KM behaviors.

Health information technology (HIT) can help in improving care only if physicians faithfully apply their knowledge during its use. A measure of judicious HIT use has recently been proposed. Behavioural research and the oft-cited technology acceptance model suggest that beliefs/perceptions may also represent decision factors. This paper proposes a perception scale and an alternative measure of judicious HIT use.Methods: Statistical analyses were performed on a subset of survey data collected for developing an eHealth success model. This paper focuses on deriving a structural equation model that can explain the associations among intent to use HIT, professional concerns and perceptions about the impacts of HIT on care benefits.Results: The statistical results show that altruism, autonomy, the physician-patient relationship, (subconscious) autonomy, efficiency and efficacy significantly associate with ...

Thus, a philosophical enquiry into the compatibility of economics and medicine is necessary to resolve the disagreements. The fundamental mission of medicine obliges physicians to practise science and compassion to serve the patient's best interests. Conventional (neoclassical) economics assumes that individuals are self-interested and that competitive markets will emerge optimal states. Economics is seemingly incompatible with the emphasis of putting patients' interests first. This idea is refuted by Professor Kenneth Arrow's health economics seminal paper. Arrow emphasizes that medical practice involves agency, knowledge, trust and professionalism, and physician-patient relation critically affects care quality. The term Arrow Physician is used to mean a humanistic carer who has a concern for the patient and acts on the best ...
