Background:
High-quality telemedicine in cases of suspected stroke has comparable precision with on-site medical examinations. A novel technical concept was developed in order to deliver a video/audio system to achieve more efficient patient assessment and diagnostic support.
Aims And Objectives:
The aim of the present pilot-study was to evaluate in a clinical setting the quality of a linked image and sound transmission in the prehospital assessment of patients with suspected stroke. In addition, we wanted to elucidate how ambulance nurses experienced the use of this innovative technology.
Design:
The study used a quantitative method using questionnaires with fixed response options, combined with a qualitative approach to assess complementary statements of prehospital emergency care nurses (PEN) that had used the system.
Methods:
The study was conducted in one ambulance care office and one hospital in southern Sweden. Six PEN and one neurological specialist (Dr) expressed their perceptions based on 11 cases with suspected stroke. Responses were assessed in the dimensions of the technology (Dr - image quality/sound quality; Dr and PEN), safety, sense of increased control and uniform assessment. A questionnaire technique was used, complemented with a qualitative part of the content analysis (PEN views).
Results:
In the technology dimension, the Dr evaluated the image quality as Very good to Good (100%) while 75% of PEN answered that the digital stroke concept felt reliable to use and the digital stroke assessment is believed to increase uniform assessment. Asked if the present digital concept should be further developed and if further digital systems should be developed in general, the PEN were split in their responses (50 vs 50%), which could be related to a conception of unclear efficacy of the concept. Descriptions of the decisive comments emerged in three categories; Minor operating interference, Physician's competence crucial and Unclear efficacy.
Conclusion:
All respondents seem to have confidence in the assessed digital stroke concept. The image quality is perceived suitable in the assessment situation but the nurses expressed ambiguity about the efficiency of the entire concept. The ambulance nurses also highlighted the physician's skills and personality as important factors for further development of the concept.
