This could not have altered the findings from the data significantly. The results of this study showed that approximately three out of five children seen at the children emergency unit during the period truly had fever using rectal thermometric method while at least four out of five would be reported to have fever using tactile assessment by physicians, nurses and caregivers.
This study also evaluated the agreements between tactile assessment which is the basis for caregivers seeking hospital care and objective rectal thermometry; and demonstrated that tactile assessment of temperature by caregivers and nursing officers could fairly agreed with rectal temperatures.
The inter-method reliability of the tactile assessments between the caregivers and either of house physicians and nurses was adjudged as good using the scale proposed by Altman [ 7 ]. Though the difference was not statistically significant, caregivers were marginally more likely to correctly detect fever by tactile perceptions than either physicians or nurses.
Our data also showed that caregivers reported fever in However, the positive and negative predictive values revealed that caregivers correctly detected large number of children who had fever but at the same time likely to report fever in a number of children who did not have fever.
These findings differ from two previous reports by Whybrew et al. However, the predictive value of a positive test that is mothers detecting fever by palpation when children were truly febrile of The differences in methodology make comparisons with our results difficult.
Wammanda and Onazi defined fever as axilliary temperatures of However, we are unaware of any previous study that evaluated the appropriate duration of touch for assessing fever.
In the present study all assessors placed their hand on the patients for 4 to 6 seconds. The present study supports the utility value of tactile assessment of temperature as in other study,[ 11 ] therefore history of fever reported by caregivers should be considered significant for further evaluation.
We are unaware of studies comparing tactile assessment of temperature among physicians, nurses and caregivers. The present data showed that the sensitivity of tactile assessment of fever by caregivers was higher than by physicians and nurses but they have the lowest specificity among the three groups.
It is not unlikely that these caregivers over reported fever because of anxiety and this may imply an attempt to seek urgent attentions from the health care providers, though this could have been avoided if they could afford one form of thermometry or the other.
It is also plausible that the regular contact of caregiver with child has helped in establishing sooner the deviation from the regular normal perception of body temperature. Controversies over the reliability of tactile assessment of temperature have been variously reported; while a study reported that caregivers assessment of fever could be relied upon by health workers,[ 12 ] others cautioned about the interpretations and reliability of caregivers' reports [ 3 ].
Although the reasons for the use of different sites of the body for tactile assessment of temperature were not explored in this study, it was observed that assessors would readily choose the exposed part of the body.
The present study did not make comparisons between the use of one and more parts of the body. In a previous study, the head and neck were the commonest anatomical sites used for tactile assessment temperature [ 13 ]."When you're being touched by another person, your brain isn't set up to give you the objective qualities of that touch," says study coauthor Michael Spezio, a psychologist at Scripps College.
