Among the tasks in coping with life-threatening illness described by Kenneth Doka, the chronic phase is characterized by "living with the disease".
Kenneth Doka (1995–96) divides the process of dying into three phases, namely the acute, the chronic, and the terminal phases of dying, during which the individual initially is given the diagnosis, then lives with the disease and ultimately surrenders to death.
This phase can be quite long and the supporters may become comfortable in their caregiving role and adjust to the notion of death. This is an important adaptation since a great deal of the care for the terminally ill is given by the family members.
Doka (1998) notes that this phase "is often a period of continued stress, punctuated by points of crisis".
