Article Synopsis
- The study aimed to adapt the Inappropriate Diagnosis of UTI (ID-UTI) measure for use in Critical Access Hospitals (CAHs), assessing its feasibility, validity, and reliability.
- Only 40% of participating CAHs met the target for case submissions, with the ID-UTI metric showing high specificity (100%) but low sensitivity (48.5%) compared to physician reviews.
- While the adapted measure was reliable (93% agreement), challenges remain in ensuring its consistent application across CAHs.
We have developed a novel device for automatic sensing, luring, and imaging insects that use substrate-borne vibrational signals for identifying and locating mating partners. The device is capable of measuring the activity patterns of these insects in a local area. It is intended to be used for monitoring pest insects; the current version of the device focuses on the treehopper species (Walker, Hemiptera: Membracidae: Smiliinae) that may serve as a vector for Grapevine Red Blotch Disease.

Objective: To compare outcomes from midline catheters vs PICCs for OPAT.
Design, Setting, And Participants: This retrospective cohort study included patients who received antimicrobial therapy through a midline catheter or PICC between January 2017 and November 2023 across 69 Michigan hospitals.
Background: Asymptomatic bacteriuria (ASB) treatment is a common form of antibiotic overuse and diagnostic error. Antibiotic stewardship using the inappropriate diagnosis of urinary tract infection (ID-UTI) measure has reduced ASB treatment in diverse hospitals. However, critical access hospitals (CAHs) have differing resources that could impede stewardship.

Background: infection (CDI) may be misdiagnosed if testing is performed in the absence of signs or symptoms of disease. This study sought to support appropriate testing by estimating the impact of signs, symptoms, and healthcare exposures on pre-test likelihood of CDI.
Methods: A panel of fifteen experts in infectious diseases participated in a modified UCLA/RAND Delphi study to estimate likelihood of CDI.
