User perceptions of different monitor modalities during high-fidelity simulation: Visual-Patient-avatar, Split Screen and Conventional - a semiquantitative analysis
ABSTRACT
Background:
Patient safety during anaesthesia is crucially dependent on the monitoring of vital signs. However, the values obtained must also be perceived and correctly classified by the attending care providers. To facilitate these processes, we developed Visual-Patient-avatar- an animated virtual model of the monitored patient, which innovatively presents numerical and waveform data following user-centred design principles. After a high-fidelity simulation study, we analysed participants' perceptions of three different monitor modalities, including this new technique.
Objective:
After a high-fidelity simulation study, we analysed participants' perceptions of three different monitor modalities, including this new technique.
Methods:
This study was a researcher-initiated, single-centre, qualitative study. We asked 92 care providers right after finishing three simulated emergency scenarios about their positive and negative opinions concerning the different monitor modalities. Following qualitative research methods, we processed the field notes obtained and derived main categories and corresponding subthemes.
Results:
We gained a total of 307 statements. Visual-Patient-avatar was the most occurring term in both positive and negative responses. We identified three main categories and divided them into eleven positive and negative subthemes. In assigning the statements to one of the topics, we achieved substantial inter-rater reliability. Most of the statements concerned the design and usability features of the avatar, respectively, the Split Screen mode.
Conclusions:
This study qualitatively reviewed the clinical applicability of the Visual-Patient-avatar technique in a high-fidelity simulation study and revealed strengths and limitations of the avatar only und Split Screen modality. We received valuable suggestions for improving the design. The requirement of training before clinical implementation was reinforced. The responses regarding the Split Screen suggested that this symbiotic modality generates improved situation awareness combined with numerical data and accurate curves.
