Development and implementation of Information and Communication Technology (ICT) are required to improve patient care. In this study we propose a cost evaluation of hospital medical consultation taking into account the level of deployment and the integration of Health Information Systems (HIS) along with a performance evaluation approach to evaluate HIS implementation scenarios considering both quantitative and qualitative performance indicators.


Micro costing techniques have been used to calculate direct costs related to medical equipment and human resources with the hospital point of view. Data has been collected through observations and hospital surveys. Sensibility analyses have been conducted on the main cost vectors. Discrete-event simulation (DES) has been used to model and simulate scenarios to determine the elements of the HIS providing the best improvements.


The study has been conducted on 179 patients from three hospitals with various level of HIS. The relative cost of the HIS is low (3 to 6 % of total cost). However, the usage rate of computers is high when the HIS is well deployed and integrated (30 to 40 % of total duration). A small reduction of consultation duration thanks to HIS allows a drastic reduction of the total cost. DES shows that the implementation of numeric patient file, voice recognition report dictation, and HIS integration are the best improvements to reduce costs.



The cost analysis coupled with a performance evaluation study allows to conclude on the impact of HIS on the consultation and it is possible to point out the best actions to take to improve the overall performance of the consultation. However the consultation duration depends on factors which was not taken into account, such as doctors’ experience or global organization of hospitals. Such parameters will be taken into account in the future to generalize the proposed results.
