Brief summary

The aim of this study is to investigate the feasibility of continuous fever tracking of participants having fever symptoms in a home setting, using a core body temperature (CBT) sensor. CBT as measured by the wearable sensors will be coampared with CBT as measured by ingestible electronc pills (reference). A secondary research question is, if the CBT behavior of the the participants in a home setting can be compared to previously described CBT profiles in the literature, and if special patterns can be identified.

Design outcomes

Primary

MeasureTime frameDescription
Mean absolute error, bias and standard deviation of the predicted CBT by the wearable CBT sensor compared to the reference temperature method (ingestible electronic pill)48 hoursThis comparison will be done for each position of the wearable CBT sensor (apical, upper arm and wrist).

Secondary

MeasureTime frameDescription
Mean absolute error, mean bias and standard deviation of the predicted CBT sensor compared to the reference temperature method (ingestible electronic pill).48 hoursIn addition to the primary outcome measure, the heartrate will be used as additional input to perform the CBT prediction of the wearables.

Other

MeasureTime frameDescription
Influence of weight on the predicted CBT48 hoursWeight measured in kg
Influence of height on the predicten CBT48 hoursHeight measured in cm
Influence of skin colour on the predicted CBT48 hoursSkin colour measured on the Fitzpatrick Skin Type Scala which classifies skin types from I to VI, depending on the amount of melanin pigment. Type I contains the lowest level of melanin, whereas type VI has the highest level.
Influence of age on the predicted CBT48 hoursAge measured in years
Influence of food intake on the predicted CBT48 hoursThe impact of the above mentioned factor on the CBT will be monitored and recorded in a participant diary
Influence of concomitant medications on the predicted CBT48 hoursThe impact of the above mentioned factors on the CBT will be monitored and recorded in a participant diary
Influence of hairiness on the predicted CBT48 hoursDegree of hairiness expressed as mild, moderate and strong
Influence of sex on the predicted CBT48 hours
