How HANDI Works
HANDI is a mobile data collection app that runs on an iOS device equipped with a barcode and magnetic stripe scanner and is supported by server and database components. During an intervention, event specific information is downloaded onto the mobile device. There are three different workflows or “stations” which may be combined or separated based on personnel and throughput for patients during the intervention process:
- Station 1 – REGISTRATION: the healthcare worker scans each patient’s driver’s license (using magnetic stripe or 2-D barcode) and collects additional data such as phone number and health insurance information. A barcode with the patient’s unique identifier is printed and given to the patient for presentation at the next stations.
- Station 2 – INTERVIEW/CONTRAINDICATION: the patient’s barcode sticker is scanned, and the patient is asked customizable health questions specific to the intervention.
- Station 3 – DOCUMENTATION: the patient’s barcode sticker is scanned, and intervention specific data (e.g., manufacturer, lot number) are recorded, the dosage and site are determined if applicable, and the vaccine or drug is given. A card with vaccine or drug information is provided to the patient.
After the station-specific workflow is completed, data are saved on the device and transferred to the application server either real-time or when a connection is established. The server aggregates the data from each station using the unique id, and the complete patient record is securely transferred to designated databases or registries (e.g., state immunization registry).
