Improving patient care through objective detection and monitoring for delirium
DeltaScan revolutionises delirium care
The development of DeltaScan was initiated by clinicians with the aim to improve patient recovery by detecting delirium more often and earlier. Better recognition is beneficial not only for patients and their relatives, but also for clinicians and budget holders. Guidelines prescribe that patients with an increased risk of delirium should be monitored at least once per shift.
We developed Prolira-DeltaScan to detect delirium more frequently and earlier. Our goal is to improve the quality of care, as better detection of delirium leads to better patient outcomes, shorter hospital stays and a reduction in healthcare costs. DeltaScan is an objective medical device that works on the basis of 1-channel EEG signal (Electroencephalography). EEG has proven to be a biomarker for delirium (Source: Van der Kooi et al., 2015, Chest). The result of DeltaScan is a parameter for delirium.
The 1-channel EEG, made by DeltaScan, clearly shows a difference between a delirious and a non-delirious patient (Source: Van der Kooi et al., 2015, Chest). Delirium is characterized by strong and strongly delayed waves in an EEG (Source: Van der Kooi et al., 2015, Chest / Kimchi et al., 2019, Neurology).
These waves are called polymorphic Delta waves (figure 1). When there is no delirium, these waves don’t present themselves (figure 2).
Medical device based on EEG
EEG (electroencephalographam) is the depiction of the electrical activity in the brain. As delirium is acute failure of the brain, DeltaScan is a practical device for detection and monitoring for delirium in patients. DeltaScan can be used by healthcare professionals (nurses and doctors) at the patient’s bedside. The patient’s brain activity is rapidly measured and DeltaScan detects and quantifies those specific waveshape patterns in the EEG, that are characteristic for delirium (also called Polymophic Delta (PMD).

Delirium detection and monitoring
Compared to current subjective screening methods for delirium, DeltaScan aims to improve the “patient journey” of patients at risk of delirium.
