Patients admitted with spinal injuries following trauma require careful serial examinations to detect any neurological deficit that may develop. Thorough documentation of the findings is of paramount importance. Enforced working practice within the NHS means that these patients are often assessed by different members of staff with varying levels of experience, thus inconsistent documentation can be a cause for concern. The project aim was to design a Human Computer Interface to standardise the performance and documentation of serial neurological examinations in patients with spinal injury, allowing the user to accurately detect any neurological deterioration. A prototype system was developed for ward based PC’s incorporating the essential requirements of the neurological examination. Usability testing was performed on the prototype by recruiting fifteen users who would be expected to routinely perform the neurological examination on spinal injury patients. Usability was defined by a number of well defined goals (impression, efficiency, learnability, memorability, safety and effectiveness) and methods used in the evaluation included direct observation during completion of tasks, a questionnaire and unstructured interview. Both quantitative and qualitative data was collected. This data was subsequently analysed using descriptive and inferential methods. The results of the analysis showed that the users responded favourably to the prototype in respects to the all usability goals except efficiency. This lack of efficiency was expected due to the rigid nature of computer based systems compared to paper based methods of recording data but this disadvantage was more than compensated for by the increased patient safety that the system would provide. It can be concluded from the usability testing that the prototype achieves the aims of the project but further work is required in developing the prototype into a final interface design before beta testing in a clinical environment can be considered.
