Ergonomic analysis of clinical activities
Stakeholder workshops were held for each of three domains: ambulance; hospital (emergency departments), and community (minor injuries units and urgent primary care). This determined the range of treatment activities to be included.
Observational and interview data were collected at two sites (East Midlands and South West England) for the identified treatment activities in order to analyse the performance of clinical tasks, including the frequency of task occurrence and physical performance. Hierarchical Task Analysis (HTA) was used to describe the detailed actions and plans occurring in the tasks as well as the range of differences in task activities and order. Physical movements were recorded and analysed using Link Analysis (LA), where links were defined as movements of position and communication. The ambulance data were collected using simulations with an adult completecrisis mannequin programmed to provide real-task scenarios in a healthcare ergonomics laboratory.
The outputs of this work were used to create detailed designs for both the patient treatment space and equipment bags required for a defined range of relevant clinical conditions.
