Background and study aims
Biometrics is the measurement and statistical analysis of people's unique physical and behavioral characteristics. The technology is mainly used to identify individuals based on these characteristics. Although there are many validated technologies to recognize adults, these technologies have been ineffective in newborns and young children. The present work describes the development and clinical testing of a fingerprint capture system designed for biometric recognition of newborns and young children for vaccination and clinical follow-up. This study aimed to test the new system in a newborn ward and immunization clinic at an urban hospital in Baja California, Mexico.

Who can participate?
Healthy infants aged less than 35 weeks

What does the study involve?
Prototypes of a biometric device are used to capture several images of an infant’s finger, foot, and/or hand prints. The study team may take photos and videos of the interactions. Parents/guardians will be asked to sign a separate consent to allow the team to record and/or photograph the infant’s movements.

What are the possible benefits and risks of participating?
Participation in this study will not involve any physical risks or discomforts. There is the risk of loss of confidentiality due to the child’s participation in this study. To minimize this risk, the team will assign each participant a study ID number and this will be used rather than the parent/guardian or child’s name.
Because this is a research study, there may be some unknown risks that are currently unforeseeable. Participants will be informed of any significant new findings. There is no direct benefit to the child participating in this study. The investigators, however, may learn more about biometric identification of infants that will be very important to children’s health around the world.

Scientific titleBiometric recognition of newborns and young children for vaccinations and health care using non-contact fingerprinting: a non-randomized prospective clinical trial
Study objectivesReliable infant (0-12 months) biometric identification is critical for effective healthcare yet has historically proven difficult to carry out. While the fingerprint is completed at around 4 months of gestation, accurate and reliable infant fingerprinting has posed significant problems over adult identification in many settings. This study is testing a device developed using principles of human-centered design to reliably capture and identify infant fingerprints.

Health condition(s) or problem(s) studiedBiometric recognition of newborns and infants
InterventionParticipating parents are consented and enrolled. Fingerprints from each infant finger are captured using a non-contact imaging device. Multiple images are taken for each finger. Enrollment of fingers occurs on the first visit and takes 10-20 minutes. On subsequent visits the child’s finger is again scanned multiple times. Matching and processing are carried out retrospectively after encounter completion.

PhaseNot Applicable
Drug / device / biological / vaccine name(s)Not applicable
Primary outcome measureEnrollment goal reached, assessed using a target of 500 participants - consented parents and at least one participant encounter between 01/01/2018 and 31/12/2020
Secondary outcome measures1. Failure to enrol rate, assessed using an image quality cutoff score and defined as no fingers with images of quality equal to or greater than this threshold from any image taken at time of encounter
2. Detection error tradeoff, assessed using standard methods for calculation of true positive and negative versus false positive and negative rates to determine thresholds optimizing sensitivity and specificity using data calculated after session encounters
3. Identification rates assessed using comprehensive match characteristics method ranking an individual match across many participants at 0-720 days time between enrollment and identification

IPD sharing planAll reasonable efforts will be made to keep the neonate’s personal information confidential. The video recordings will be used for device development and destroyed at the completion of the study. The researchers will not collect any other protected health information (PHI) or any personal information that might lead to individual identification. No PHI will be used in any reports or publications about this study. There is the risk of loss of confidentiality due to disclosure is required by law or through University of California San Diego organizations that may inspect and/or copy research records for quality assurance and data analysis.
Several methods will be used to ensure confidentiality. Patient identifiable information will not be recorded in the study database or in any subsequent analysis. All collected data will be recorded with a sequential patient identification number. The key linking study ID to identifiable information will be retained in a password-protected file and/or in a locked location, accessible only to the research team and separate from other study data. The study database will be password protected and stored on a secure server. The information will not be disclosed without consent except where required by law. The results of the study when published will have no patient identifying PHI. Videos will also be maintained in a password-protected file and/or in a locked location accessible only to the research team.
Patients will be assigned a study ID number which will be used for study purposes. The key linking study ID numbers to identifiable information will be kept in a password-protected file and/or in a locked location separate from all other study data. Upon completion of the publication of findings, the key that links PHI data to subject ID will be destroyed. The study database will be stored on a password-protected computer file on a secure server with access restricted to study members. No PHI will be presented or published. PHI will be destroyed after the study/manuscript is complete and no further analysis will be performed.
