Describes part of a wider evaluation exercise undertaken to assess the impact of the introduction of a picture-archiving and communication system (PACS) on the adult intensive care unit (AICU) at the Royal Brompton NHS Trust in London. The objectives of this research were to evaluate the perceptions of PACS of the medical and ancillary staff working within AICU as well as to undertake a preliminary assessment of its impact on the workload of radiographers. Questionnaires, interviews and a process analysis were undertaken. The research findings indicate that the overall perception of staff towards the introduction of the PACS was positive. The impact of the system on the workload of radiographers was significant, reducing the time taken to obtain an image from 90 to 60 minutes. However, lessons to be learned for future PACS implementations include the need to ensure compatibility with existing IT systems, adequate IT support and initiatives to ensure that the benefits of PACS are communicated to the hospital at large.
