Work system design – SEIPS PETT scan
Work system factors were analysed using a SEIPS PETT scan for all three
tasks. Results for participant inoculation are shown in Table 2 and for
general work activities in Table 3 (for in room assessment and
participant transfer to CT see Supporting Information File 1). The PETT
scans revealed barriers and facilitators to safe practice in each
category, including the issues around enforced rule breaking and
standardisation identified above.
Analysis of protocolised tasks identified that the infrastructure for
research teams working within the OxCRF is not yet optimised. For
example, no specified quiet area for rest was available. Staff working
overnight have found workarounds (e.g. by using a separate clinical
space) but the importance of adequate rest is well recognised .
Potential alterations to staff areas to improve privacy and adaptations
to audio-visual systems to enhance the ability to observe and
communicate with participants when necessary (without significantly
impacting their privacy) were flagged.
Over the course of the study several additional matters arose which,
whilst not formally observed, may have represented potential safety
risks. This is exemplified by the unexpected occurence of groundworks
outside the main CRF entrance, which would have impeded access in a
clinical emergency (see Supporting Information File 2).
Overall, risks were evident in all SEIPS work system categories and
their identification informed recommendations to improve safety.
