A Novel Non-Invasive Thermometer for Continuous Core Body Temperature: Comparison with Tympanic Temperature in an Acute Stroke Clinical Setting

There is a growing research interest in wireless non-invasive solutions for core temperature estimation and their application in clinical settings. This study aimed to investigate the use of a novel wireless non-invasive heat flux-based thermometer in acute stroke patients admitted to a stroke unit and compare the measurements with the currently used infrared (IR) tympanic temperature readings. The study encompassed 30 acute ischemic stroke patients who underwent continuous measurement (Tcore) with the novel wearable non-invasive CORE device. Paired measurements of Tcore and tympanic temperature (Ttym) by using a standard IR-device were performed 3−5 times/day, yielding a total of 305 measurements. The predicted core temperatures (Tcore) were significantly correlated with Ttym (r = 0.89, p < 0.001). The comparison of the Tcore and Ttym measurements by Bland−Altman analysis showed a good agreement between them, with a low mean difference of 0.11 ± 0.34 °C, and no proportional bias was observed (B = −0.003, p = 0.923). The Tcore measurements correctly predicted the presence or absence of Ttym hyperthermia or fever in 94.1% and 97.4% of cases, respectively. Temperature monitoring with a novel wireless non-invasive heat flux-based thermometer could be a reliable alternative to the Ttym method for assessing core temperature in acute ischemic stroke patients.

When interactions are interruptions: an ethnographic study of information-sharing by speech and language therapists and nurses on stroke units

PURPOSE

To explore how the information-sharing context influences how speech and language therapy (SLT) and nursing staff interact on stroke units and what they discuss.

METHODS

Ethnographic methodology was used, with data collected during 40 weeks of fieldwork across three inner city stroke units in the UK. Data comprised field notes collected during 357 h of participant observation and 43 interviews. Interviews were conducted with 14 SLTs, 1 SLT assistant, 24 registered nurses and 4 nursing assistants.

RESULTS

This paper is focused on informal information-sharing. SLTs and nurses had different experiences of time and space (the temporal-spatial context) with respect to ward presence and proximity to patients, influencing how they interacted, the content of their talk and their relationships. Most interactions had the quality of interruptions, in which SLTs seized moments in between nursing tasks. Conditions were less suited to sharing information about communication than swallowing and SLTs felt more allied to other therapists than nurses.

CONCLUSION

The temporal-spatial context impeded information-sharing, particularly about patients' communication needs. Consideration should be given to developing relationships between SLTs and nurses as key partners for patient care and raising the profile of communication information in ways that are relevant and useful to nursing work.Implications for rehabilitationStrategic waiting for opportunities to interrupt nurses and gain their attention is central to how speech and language therapists manage their need to share information informally with nurses.The small "windows in time" available for interaction influence information-sharing, with a limiting effect on information about patients' communication.There is potential to improve information-sharing between speech and language therapists and nurses by considering how the relevance of information for patient care could be made clearer.
