Background: An efficient testing process is a key to a timely diagnosis of acute myocardial infarction in the emergency department (ED). This includes a rapid evaluation cardiac biomarkers.
Methods: We conducted a quality and process improvement project to reduce troponin-T turnaround time (TAT) in the central laboratory at our facility. An interdisciplinary team, including front-line staff members, reviewed each step of troponin-T processing in both the ED and the central laboratory. A series of improvements were implemented during 2013, including changes to specimen labeling, elimination of duplicate test ordering, and efficiencies within the laboratory. Data from January 2013 to December 2014 on 31,496 patients with troponin tests were included in the analysis.
Results: Over the 2-year period of the projects, median troponin-T TAT decreased from 74 minutes to consistently less than 60 minutes.
Conclusions: With an interdisciplinary team of health care professionals, we successfully reduced troponin-T TAT for possible acute coronary syndrome patients in our ED by 19%, consistently achieving laboratory results in less than 60 minutes.

A Comprehensive Review of the Diagnostics for Pediatric Tuberculosis Based on Assay Time, Ease of Operation, and Performance.

Pediatric tuberculosis (TB) is still challenged by several diagnostic bottlenecks, imposing a high TB burden in low- and middle-income countries (LMICs). Diagnostic turnaround time (TAT) and ease of operation to suit resource-limited settings are critical aspects that determine early treatment and influence morbidity and mortality. Based on TAT and ease of operation, this article reviews the evolving landscape of TB diagnostics, from traditional methods like microscopy and culture to cutting-edge molecular techniques and biomarker-based approaches.

Background: Bloodstream infection (BSI) is a systemic infection that predisposes individuals to sepsis and multiple organ dysfunction syndrome. Early identification of infectious agents and determination of drug-resistant phenotypes can help patients with BSI receive timely, effective, and targeted treatment and improve their survival. This study was based on matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), Decision Tree (DT), Random Forest (RF), Gradient Boosting Machine (GBM), eXtreme Gradient Boosting (XGBoost), and Extremely Randomized Trees (ERT) models were constructed to classify carbapenem-resistant Escherichia coli (CREC) and carbapenem-resistant Klebsiella pneumoniae (CRKP).

Next-generation sequencing (NGS) can explain how genetics influence morbidity and mortality in children. However, it is unclear whether health providers will perceive and use such treatments. We conducted a discrete choice experiment (DCE) to understand Italian health professionals' preferences for NGS to improve the diagnosis of paediatric genetic diseases.

Accurate and timely diagnosis of t(9;22)-positive leukemias is vital to improving survival in pediatric patients. In low-resource settings, where healthcare disparities are exacerbated by limited resources, cost-effective and efficient diagnostic methods are essential for bridging these gaps and ensuring better outcomes. Among the diagnostic tools evaluated among 23 patients sample, RT-PCR demonstrated superior sensitivity (100%) and the shortest turnaround time (7 days), significantly outperforming FISH and karyotyping in both accuracy and timeliness.
