AI Technical Summary

Problems solved by technology

Changes in muscular motor action are not limited to one part of the body and measurements of only one extremity may result in missed movements and thus an underestimation of delirium
Additionally, additional on-body sensors may irritate or confuse patients

Embodiment Construction

[0038] figure 1 A block diagram of a first embodiment of a monitoring system 1 according to the invention is shown. The monitoring system 1 comprises a monitoring unit 10 for acquiring image data 30 of a patient over time. The monitoring unit 10 comprises eg one or more image sensors or cameras for acquiring image data 30 , eg new images at certain time intervals (eg every second), or continuous video data. Furthermore, the monitoring system 1 comprises an image analysis unit 12 for detecting motor events from the obtained image data, an evaluation unit 14 for classifying detected motor events into delirium-typical motor events and non-delirium-typical motor events, and A delirium determination unit 16 for determining a delirium score 32 indicating the likelihood and / or severity of delirium in the patient from the duration, intensity, type, location and / or occurrence of delirium-typical motor events.

[0039] In an embodiment, the image analysis unit 12, the evaluation unit ...

Abstract

The present invention relates to a monitoring system (1, 2, 3) and a corresponding monitoring method for monitoring a patient and detecting delirium of the patient in an unobtrusive manner without the need of on-body sensors. The proposed monitoring system comprises a monitoring unit (10) for obtaining image data (30) of the patient over time, an image analysis unit (12) for detecting motion events of the patient from the obtained image data (30), an evaluation unit (14) for classifying the detected motion events into delirium-typical motion events and non-delirium-typical motion events, and a delirium determination unit (16) for determining a delirium score (32) from the duration, intensity, type, location and / or occurrence of delirium-typical motion events, said delirium score (32) indicating the likelihood and / or strength of delirium of the patient.

Description

technical field [0001] The invention relates to a monitoring system and a corresponding monitoring method for monitoring a patient and detecting delirium in said patient. Furthermore, the invention relates to processors and corresponding processing methods for use in such monitoring systems. Furthermore, the invention relates to a computer program for implementing the processing method. Background technique [0002] Delirium is a neuropsychiatric syndrome with multifactorial etiology that occurs in a large number of ICU (intensive care unit) patients. Delirium is associated with increased mortality, prolonged hospital stay, and long-term effects such as reduced independent living, increased rates of hospital admissions, and increased risk of developing long-term cognitive impairment. Longer hospital stays and complications associated with delirium in the ICU lead to significantly higher costs of care. The prevalence of delirium in the ICU ranges from 11% to 87%. Accurate...
