Prolira-DeltaScan

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.

Prior to measurement, a DeltaScan Patch is applied to the patient’s head and removed following measurement. Immediately after the measurement, which takes a few minutes, the DeltaScan score is visible on the device. The score is a number on a scale from 1 to 5, where 1 corresponds to “very unlikely delirium” and 5 to “very likely delirium”. This objective measurement helps to detect delirium better (> 90% accuracy) and earlier (1-1.5 days on average), compared to usual care (use of questionnaires) (Source: Unpublished data, available on request). 

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 (e.g. VMS positive).
