Article Synopsis
- Guidelines suggest using risk scores to identify very-low-risk patients with gastrointestinal bleeding (GIB) for possible discharge from emergency departments.
- A new machine learning model was developed and tested against existing scores (Glasgow-Blatchford and Oakland) using data from nearly 3,500 patients across different hospitals.
- Results showed the machine learning model performed better in predicting very-low-risk patients, successfully identifying a higher percentage compared to the existing risk scores.
Article Synopsis
- Reducing the shelf-life of red blood cells (RBCs) from 42 days to 35 and 28 days was studied to evaluate its effects on blood supply chain management.
- The study found that a shorter shelf-life significantly increased the outdate rate of RBCs and the amount of outdated redistributed units in two Canadian health authorities.
- Overall, decreasing the shelf-life led to more outdated RBCs and higher emergency (STAT) orders, suggesting that current inventory management strategies were not effective in addressing these issues.
