OBJECTIVES:
In places of mass gathering, rapid infection screening prior to definite diagnosis is vital during the epidemic season of a novel influenza. In order to assess the possibility of clinical application of a newly developed non-contact infection screening system, we conducted screening for influenza patients.
MATERIALS AND METHODS:
The system is operated by a screening program via a linear discriminant analysis using non-contact derived variables, i.e., palmar pulse derived from a laser Doppler blood-flow meter, respiration rate determined by a 10-GHz microwave radar, and average facial temperature measured by thermography. The system was tested on 57 seasonal influenza (2008-2009) patients (35.7 degrees C<= body temperature <= 38.3 degrees C, 19 to 40 years) and 35 normal control subjects (35.5 degrees C<= body temperature <= 36.9 degrees C, 21 to 35 years) at the Japan Self-defense Forces Central Hospital.
RESULTS:
A significant linear discriminant function (p<0.001) was determined to distinguish the influenza group from the control group (Mahalanobis D-square=6.5, classification error rate>10 %). The system had a positive predictive value (PPV) of 93 %, which is higher than the PPV value (PPV<=65.4) reported in the recent summary of studies using only thermography performed mainly in hospitals.
CONCLUSIONS:
The proposed system appears promising for application in accurate screening for influenza patients at places of mass gathering.
