Diagnostic accuracy of three different methods of temperature measurement in acutely ill geriatric patients

摘要: Objective: we examined the diagnostic accuracy of different methods body temperature measurement to diagnose infection in geriatric patients presenting emergency department (ED). Methods: this observational study was done consecutive ≥75 years old ED. Body determined by tympanal thermometry, temporal artery thermometry and rectal measurement. Adjudicated final diagnosis two experts including patient history, clinical laboratory findings as well radiographic studies. Results: a total 427 were included data analysis (age: 82.7 ± 5.1 years). Infection present 105 (24.6%). Respiratory rate, heart rate significantly higher with infection, blood pressure lower (P< 0.01). measured correlated thermometry. compared those without independent method 0.001). The for quantified area under curve (AUC) comparable among [AUC: 0.72 (95% CI: 0.65–0.80)] 0.73 0.66–0.81)], but 0.65 0.57–0.73; P< 0.001)]. Compared showed bias than (0.54 versus 0.03°C), while its limits agreement more narrow (−0.14 1.21°C −0.94–1.01°C). Conclusion: identification Different cut-off points should be used identify using (37.3° C) or (37.9°C) In general, is an insensitive infection. Registration number clinicaltrials.com: KSMC-tempger-1.
