About this study

Assessment and evaluation of body temperature is an important sign of health and disease. Inferior thermometry increases the risk of morbidity and mortality, and increases health care cost by delaying the diagnosis and treatment of fever-related disease. The gold standard for measuring core body temperature is the pulmonary artery thermistor (PAT). The measurement of the PAT requires the insertion of the invasive pulmonary artery catheter, a high risk procedure.

An innovative thermometry technology, the temporal artery thermometer (TAT), has been introduced into the clinical arena as a potential non-invasive proxy for the PAT. The TAT reduces the risk and cost of pulmonary artery catheter insertion by non-invasively measuring core blood temperature by measuring temperature over the skin of the temporal artery.

Research to demonstrate the precision and accuracy of the TAT in normothermic patients has been published, but little to no data is available in those with temperatures greater than 100.4oF. The purpose of this study is to measure the precision and accuracy of 2standard of care temperature methods: the thermistor from the PAT, considered the gold standard, and the TAT as measured in those patients with a PAT temperature greater than 100.4oF.

Read the detailed description

The results from previous studies agree that direct comparisons of the PAT and TAT are clinically comparable in the normal temperature range in adults. This was defined as a clinical significance difference of less than ±.5ºC (.9ºF. In the one study that assessed subjects with fevers (temperatures greater than 37.8oC (100.0oF) with some methodological criticism, compared the TAT to PAT in adults (n=15). There were poor correlations (r=0.3) among the adult measurements with a difference of 1.3+0.6o C. Eighty-nine percent of the TAT measurements were different than the PAT by more that ±.5ºC.

With only one study that focused in those who had a PAT outside the normal temperature range to evaluate accuracy and precision, there is a need for further research to assess the accuracy and precision of the TAT for detection of hyperthermia. A new onset of temperature equal to or above 100.4oF is defined as a fever and a temperature of 100.9oF is considered a reasonable trigger for a clinical assessment according to the Society of Critical Care Medicine in their fever guidelines for adults. Researchers synthesizing the literature on the TAT and other noninvasive temperature measurements, indicate that noninvasive temperature measurements are accurate for normal temperatures but may fail to detect hyperthermia and hypothermia, depending on the thermometer used. The authors concluded that the TAT is clinically comparable to the PAT in only the normal temperature range.

A repeated measures design will be used to describe the accuracy and precision of 2 temperature measurements, the PAT and the TAT. Study subjects will act as their own control in order to investigate the difference in PAT readings and the TAT readings in both the core and oral mode. The PAT will also be compared to the TAT reading taken by the clinical staff.

Questions about this trial

What is this clinical trial studying?

An observational study of Fever, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jun 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

accuracy and precision of the TAT as compared to the PAT (time frame: 1 minute). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2014.
