Budget Impact Analysis of Adopting a One-Step Nucleic Acid Amplification Testing (NAAT) Alone Diagnostic Pathway for in Japan Compared to a Two-Step Algorithm with Glutamate Dehydrogenase/Toxin Followed by NAAT.

infection (CDI) is a major healthcare-associated infection that leads to a significant health economic burden in Japan. Using a decision tree model, we evaluated the budget impact of adopting a one-step nucleic acid amplification test (NAAT) alone pathway compared to a two-step diagnostic algorithm with glutamate dehydrogenase (GDH) and toxin antigen, followed by NAAT. The analysis was conducted from the government payer's perspective for 100,000 symptomatic, hospitalized adults requiring a CDI diagnostic test.

Diagnostic utilities of a fully automated molecular test for toxigenic Clostridium difficile.

Laboratory underdiagnosis of toxigenic Clostridium difficile can lead to inappropriate management of C. difficile infection (CDI). A fully automated molecular test (FAMT), BD MAX, and enzyme immunoassays for C.

Unfavorable peripheral intravenous catheter replacements can be reduced using an integrated closed intravenous catheter system.

Purpose: To evaluate the clinical usefulness of an integrated closed intravenous catheter system (CICS) with a preattached stabilization platform and extension tube (BD Nexiva™; Becton, Dickinson and Company) in Japanese patients.

Methods: In this open, single-center study, patients who required peripheral intravenous (PIV) catheterization for ≥72 hours were quasi-randomized to receive a CICS or a conventional intravenous catheter. Study outcomes included adverse events during catheter insertion, catheter replacements during the initial 72 hours, catheter survival rate at 72 hours after insertion and costs of initial catheterization and catheter replacement.

Detection of norovirus antigens from recombinant virus-like particles and stool samples by a commercial norovirus enzyme-linked immunosorbent assay kit.

The commercial norovirus enzyme-linked immunosorbent assay kit was evaluated for its reactivity to recombinant virus-like particles and the detection of natural viruses from stool samples of Japanese infants and children with sporadic acute gastroenteritis compared to reverse transcription-PCR. The kit had a sensitivity of 76.3% and a specificity of 94.
