This study surveyed 313 parents to investigate how frequently parents used a parent-held child health record, and whether they saw the record as useful. Since 1981, The Child, Adolescent and Family Health Service has distributed a Personal Health Record (PHR) to the parents of all children in South Australia. The PHR has provided each family with an ongoing record that has been consistently used for immunization, child health checks and child health screening. However, little is known about how parents view the PHR, its usefulness, and how frequently the record is used. Previous studies, generally conducted prior to, or shortly after, a parent-held child health record was introduced, have shown a poor understanding of the uses of the PHR on the part of parents and a low level of use by health professionals such as general practitioners. In contrast, the results of this study show high levels of understanding of the health record on the part of parents, and an increase in the use of the health record by general practitioners over the 10 years since the record was introduced. Although moderated by the age of the child, the sections of the PHR seen as most useful (and the most frequently used) by parents were immunization, growth charts, progress notes and health checks.
