Patient-held records for undocumented immigrants: a blind spot. A systematic review of patient-held records.

As a result of inadequate medical record information, the medical care for undocumented immigrants in general practice is time consuming and often unsatisfactory. The availability of medical record information might improve the medical care for undocumented immigrants. Therefore, we executed a systematic review of literature to investigate the potential benefits of a patient-held record (PHR) for undocumented immigrants.
