Out-of-hours acute CT reporting at our institution has increased dramatically over 10 years, with a 400% increase in overnight CT reporting. Despite this year-on-year increase in the demand for CT, the expansion of the evening on-call team has reduced the number of scans handed over for the trainee working overnight to report, and has improved registrars' level of satisfaction in their night shifts.

Going forward, we aim to collect similar data on workload annually to monitor trends, and to expand the Visual Basic Macro to include other modalities reported out of hours, such as MRI. We also propose to create a web-based form to make qualitative data collection more straightfoward and accessible for registrars, and to repeat this evaluation for one month each year. A further direction of work would be to evaluate whether we can reduce interruptions (including consults over scan requests) to radiologists out-of-hours, as this is thought to lead to distraction when reporting [3].
