1-2-3 Device: Reducing Infection Rates

The 1-2-3 initiative started at Cincinnati Children’s Hospital with the goal of increasing patient adherence to activities of daily living (ADLs) that are proven to reduce infection rates. If patients can bathe once per day, exercise twice per day, and practice oral care three times per day, it has been shown to have a significant positive impact on their overall health. A sticker chart incentivizing patients to keep up with their ADLs was implemented that brought adherence from 25% to 66%. The Live Well team partnered with Cincinnati Children’s hospital to help further improve adherence to ADLs.

The Challenge

Patients at Cincinnati Children’s Hospital in the Cancer and Blood Disease Institute (CBDI) sometimes struggle with adherence to their ADLs. The previous incentivization and tracking system was a sticker chart maintained by nurses. After conducting observations, CBDI and the Live Well team learned that the system was inefficient, required extensive upkeep, and was often forgotten about. The team was challenged to develop a solution that was engaging for both patients and their families, while being low maintenance for the hospital staff. The device was also to serve as a visual, physical reminder for patients to complete their ADLs, while offering incentives through gamification.

The Approach

The Live Well team, composed of UX/UI designers, industrial designers, and engineers, utilized the Live Well’s multidisciplinary approach to research, ideate, and deliver a final solution. The team benchmarked technologies like RFID scanning and wearable technology to develop a unique user flow.

The team then generated sketches and designs for possible interfaces, and utilized CAD and 3D-printing technology to conduct shape explorations. Engineers on the team sourced components and developed the code alongside CBDI’s software engineering staff to deliver the final product.

The Results

The 1-2-3 Device

The final 1-2-3 device is composed of RFID profile cards that are given to each patient and family member using the device. The main 1-2-3 device unit is composed of an Arduino UNO, an RFID scanner, buttons to log activities, and a screen to display the patient’s current progress and point total. The system gamifies and automatically tracks patients’ adherence to their ADLs.

How It Works

Patients complete an activity of daily living, scan their RFID card, choose the completed activity, and have a parent or staff member verify that activity was actually completed. Once this happens, their completion of the activity is rewarded with points that can be traded in for prizes kept in a catalog by CBDI staff.

The device also has a backend portal that allows hospital staff to check in on any patient, at any time, creating a staff-to-patient connection that may not otherwise exist.

Current Work

The Live Well and CBDI teams finalized a design and built 30 1-2-3 devices to be used at Cincinnati Children’s Hospital. The devices are currently under study to determine how the implementation of this system affects patient adherence, but results to-date prove a great success.
