Abstract

A system for assessing pressure injuries in a healthcare facility. The system creates patient metadata for a patient and associates the patient metadata with medical equipment including a patient support apparatus having a controller that performs pressure injury prevention functions and a surface positioned on a frame of the patient support apparatus. The system records usage data from the medical equipment via a network interface. The usage data including duration and frequency measurements of pressure injury prevention functions. The system receives sensor data from sensors positioned on the patient support apparatus. The sensor data includes weight distribution and patient movement measurements. The system pairs the usage data and the sensor data to the patient metadata to create survey data that correlates patient risk factors with therapeutic interventions performed by the medical equipment and stores the survey data in a database accessible for automated completion of a survey.

Claims20

Dependent claims

A system for assessing pressure injuries in a healthcare facility, the system comprising:

at least one processing device;
and
a memory device storing instructions which, when executed by the at least one processing device, cause the at least one processing device to:
create patient metadata for a patient;
associate the patient metadata with medical equipment including a patient support apparatus having a controller configured to perform pressure injury prevention functions and a surface positioned on a frame of the patient support apparatus;
record usage data from the medical equipment via a network interface, the usage data including duration and frequency measurements of pressure injury prevention functions including a surface mode function that controls inflation of the surface, a turn assist function that inflates zones of the surface to turn the patient left or right, and a rotation function that provides continuous lateral rotation;
receive sensor data from one or more sensors positioned on the patient support apparatus, the sensor data including at least weight distribution and patient movement measurements;
pair the usage data and the sensor data to the patient metadata to create survey data that correlates patient risk factors with therapeutic interventions performed by the medical equipment;
and
store the survey data in a database that is accessible for automated completion of a survey that assesses the prevalence of the pressure injuries in the healthcare facility.

7 more elements

A method of mitigating pressure injuries within a healthcare facility, the method comprising:

creating patient metadata for a patient;
associating the patient metadata with medical equipment including a patient support apparatus having a controller configured to perform pressure injury prevention functions and a surface positioned on a frame of the patient support apparatus;
recording usage data from the medical equipment via a network interface, the usage data including duration and frequency measurements of pressure injury prevention functions including a surface mode function that controls inflation of the surface, a turn assist function that inflates zones of the surface to turn the patient left or right, and a rotation function that provides continuous lateral rotation;
receiving sensor data from one or more sensors positioned on the patient support apparatus, the sensor data including at least weight distribution and patient movement measurements;
pairing the usage data and the sensor data to the patient metadata to create survey data that correlates patient risk factors with actual therapeutic interventions performed by the medical equipment;
and
storing the survey data in a database that is accessible for automated completion of a survey that assesses the prevalence of the pressure injuries in the healthcare facility.
