Abstract
Nagoya University Hospital is designated as a regional disaster base hospital in Aichi Prefecture. According to the Business Continuity Plan (BCP) formulated by our hospital, it is assumed that the external infrastructure around the hospital during a disaster will be shut down for two weeks for water supply and three days for electricity. However, medical treatment and preoperative examination during disasters are indispensable. The fully automated VITROS XT 7600 integrated system does not require a water supply/drainage device, and is expected to contribute to medical care during a disaster. Here, VITROS XT 7600 was used to compare the performance of the examinations for infection-related diseases that may be required during disasters with the analyzer used in the hospital, and its usefulness was verified. The hepatitis B surface (HBs) antigen, hepatitis C virus (HCV) antibody, Treponema pallidum (TP) antibody and human immunodeficiency virus (HIV) antigen/antibody were verified as the markers for infection-related diseases. The concordance rates of the results of examinations for infection-related diseases were 98.0% for the HBs antigen (98/100), 92.3% for the HCV antibody (60/65), 100% for the TP antibody (53/53), and 100% for the HIV antigen/antibody (67/67). Moreover, the early detection capability of a seroconversion panel was evaluated for the HBs antigen, HCV antibody, and HIV antigen/antibody. Results showed that the early detection capability was almost the same for all items. Taken together, it was considered that VITROS XT 7600 is useful for examinations of infection-related diseases during disasters.
