Personal identification systems for persons with dementia: a systematic review

Abstract

People with dementia can become missing and unable to be identified due to their cognitive decline and may not have belongings, including personally identifiable information. The aim of this systematic review was to summarise and discuss the current status of personal identification systems for missing and unidentified persons with dementia. An electronic systematic literature search was conducted by using PubMed, Web of Science, Cochrane Library, and CINAHL. By performing an electronic literature search, 128 texts were extracted. However, only three eligible texts were included in this review, and these were divided on the basis of the analysis target as follows: medical and human community support systems and digital systems. It is important to develop medical and social care systems and to construct and advance social personal identification systems, including medical and human community support systems and digital systems, for persons with dementia. However, this systematic review clarified that there have only been a few reports about the development and construction of social systems for missing and unidentified persons with dementia. People who interact with persons with dementia should consider this problem, which is increasing each year, and strive to build a social system that can be applied to personal identification as soon as possible.

Possibilities and challenges in digital personal identification using teledentistry based on integration of telecommunication and dental information: a narrative review

“…Cases of missing individuals are often associated with psychiatric disorders and in such cases, it may be difficult for the individual to maintain oral hygiene themselves. 2 …”

“… 28 PI methods using dental evidence based on digital technology are in the early stages of development and discussion regarding their treatment of personal information may be insufficient. 2 , 4 , 15 It is important to discuss how consent for database construction could be obtained from individuals for digital PI methods based on dental records. 25 , 26 …”

“… 1 – 4 Even today in forensic cases, PI with dental evidence is performed globally by traditional visual comparisons of the antemortem dental records with those obtained postmortem. 1 – 4 Conversely, for cases involving missing and unidentified individuals, dental information is not currently a priority in PI. 2 …”

“… 4 A digital database for PI as part of social services and humanitarian forensics, although under consideration, has not yet been implemented. 2 , 4 The construction of a database by including dental records, including images of dentition and/or teeth, casts, models and orofacial soft tissues may solve these issues in PI. 4 – 6 However, presently, there is no objective digital PI method using dental evidence that has been accepted as a standardized method worldwide owing to various factors.…”
