Home health care allows individuals to receive care in a home setting rather than a medical facility. This increasingly popular alternative to health care has many benefits; however providing health care in a home setting involves unique challenges and difficulties for the health care providers such as certified nursing assistants (CNAs). Human factors interventions and technological supports may ease difficulties home health care providers experience performing caregiving tasks. However for such interventions to be effective there is a need to understand patient care within the context of a home environment. The purpose of this research was to conduct a needs assessment to identify 1) personal caretask characteristics including the context in which they are carried out and 2) challenges encountered during these tasks. Eight CNAs participated in structured interviews where in they were asked to describe difficulties and frustrations experienced when performing the tasks of toileting bathing and transfer. The results were categorized as patient- or provider-based difficulties as well as along dimensions related to the environment device design and social influences. These data provide an understanding of the complexity of each task and a means of highlighting areas of difficulty to provide guidance for designers of assistive technologies and other supportive interventions.
