example 2

[0109] Example 2 (for air prevention):

[0110] Patient P1 is lying on bed B1 in room R1.

[0111] P1 has a currently undetected infectious medical condition and M1 involves the pathogen PG1.

[0112] PG1 can spread via airborne transmission.

[0113] PG1 has a lifespan outside the human body of 5 hours.

[0114] 1 hour after P1 has been placed in R1, nurse N2 enters room R2 to fetch some supplies.

[0115] Room R1 and R2 share ventilation

[0116] Nurse N2 inhales PG1 in R2

[0117] N2 followed by M1 after 24 hours.

[0118] Parameters are entered into the system. The system forms a directed graph.

[0119] The directed graph shows that there is an edge between P1 and N2 due to the shared ventilation between R1 and R2.

[0120] Move P1 to an independently ventilated room and isolate N2.

Abstract

A system (10) includes a real-time locating system (RTLS) (12) configured to track locations of tags (14, 15) in a monitored area. A non-transitory storage medium stores, a map (30) of the monitored area; a nodes database (32) storing information on nodes (18); and a pathogen database (34) storing infectious transmission information. The non-transitory storage medium includes instructions readableand executable by an electronic processor to perform an infectious disease transmission tracking method (100) including: computing a pathway (35) on the map of at least one infected node using locations of the tag wherein an infected node has a non-zero infection likelihood; computing an infectious zone (36) on the map along the pathway; for each node contacting the infectious zone, adjusting theinfection likelihood of the contacting node and designating the contacting node as an infected node if the updated infection likelihood of the contacting node satisfies an infected criterion.

Description

technical field [0001] The following generally relates to patient monitoring technologies, patient care facility monitoring technologies, infection control technologies, tracking system technologies, and related technologies. Background technique [0002] Infection control is the discipline of combating hospital-acquired infections, or healthcare-associated infections (HAIs). HAI is an infection whose development is favored in hospital settings, nursing homes, rehabilitation facilities, clinics, or other clinical settings. This infection spreads to patients in a number of ways in clinical settings. Health care workers can spread infection, contaminated equipment, bedding, or airborne droplets. The infection may have originated from another infected patient or hospital staff, or in some cases, the source of the infection could not be determined. [0003] According to the US Centers for Disease Control and Prevention, there were an estimated 722,000 HAI events in US acute c...
