  1. Evaluation of a hospital picture archiving and communication system.

    Article - En anglais

    0bjectives : To establish the net costs to the hospital and the broad range of benefits associated with a hospital-wide picture archiving and communication system (PACS) that comprised digital acquisition, storage and transmission of radiological images via a hospital-wide network to 150 workstations.


    « Before and after » comparisons and time series analyses at Hammersmith Hospital (London, UK), and comparison with five other British hospitals where PACS was not being installed.

    The cost analysis considered implementation costs and changes in key elements of hospital running costs, including the impact of changes in the length of inpatient stays.

    A range of benefit measures were investigated, including image availability, avoidance of repeat imaging, avoidance of exposure to radiation, patient turn-round speed, time from examination to image availability in intensive care, avoidance of diagnostic « errors » by casualty doctors, the additional diagnostic value of PACS-based images and clinician satisfaction.


    The annual equivalent capital cost of the PACS was £1.7 million (annual equivalent replacement cost : £0.8 million).

    Overall, the PACS substantially increased running costs.

    No convincing evidence of a PACS-induced change in length of inpatient stay was found.

    PACS was associated with some improvements in the performance of the radiology department : improved image availability (97.7% versus 86.9%), lower repeat imaging rate (7.3% versus 9. (...)
