Hybrid Patient Record Device
The patient record is one of the central artifacts in medical work that is used to organize, communicate and coordinate important information related to patient care. In many hospitals a double record consisting of an electronic and paper part is maintained. This practice introduces a number of configuration problems related to finding, using and aligning the paper and electronic patient record. To support this dual record in nomadic work, we introduce the notion of a Hybrid Patient Record (HyPR) that consists of (i) a classic paper record, (ii) a tablet, phone or other mobile devices that provides access to the EHR and (iii) a HyPR device, a mediating sensor platform that augments the paper record with a notification system (color and sound), location tracking and ad hoc integration to a tablet that provides access to contextual relevant electronic patient data.
A Hybrid Patient Record (HyPR) device is a rectangular plastic plate with the same width and height as the paper record. The PMR is attached to the plastic plate using metal clips to create a permanent fusion to the device. Each paper record thus has one unique attached HyPR device. Clinicians can interact with the HyPR by placing a tablet or phone on top of augmented paper record. This causes the underlying infrastructure to pair the mobile device to the record and pushes the EHR to that mobile device. Any changes made to the record are updated and synchronized in real time with all other devices. The HyPR device is thus a small configuration space that provides clinicians with quick and easy access to patient data by physical proximity between the mobile device and augmented paper record. This dramatically reduces configuration work during, e.g., ward rounds or emergency situations in which manually finding the patient data would be too time consuming or inappropriate. To comfortably carry both the augmented paper record and mobile device, microsuction tape is attached to the paper record to keep the tablet or phone attached to the record. Once the mobile device is paired to the record it can be moved and used separately without loosing the connection. Device can also be remotely connected to the HyPR device by simply looking up the patient case in the application. Once the devices are paired, the clinician can modify the color scheme of the led matrix that is built into the HyPR device, to signal status information. The lights can also be set to ‘blink’ in different patterns to signal more complex workflows such as the arrival of new blood test. Clinicians can also turn on a sound signal on the device, which can be used to help locate records, which may be scattered over the ward or located in a cupboard. The HyPR device is also equipped with an ultrasound location tag that can be used to look up where the paper record is located.
