The alert system effectively detected hyperkalemia risk, improving patient management and repeat testing needs.
Among 54,605 samples, the positive predictive value for hyperkalemia detection was 41.3%, indicating some margin for improvement.
Women had a higher rate of invalidated potassium tests due to haemolysis compared to men, emphasizing the need for alerts.
Hyperkalemia was significantly more frequent in patients with an initial alert, suggesting the alert system's reliability in predicting potassium levels.
