For some diseases, such as advanced cancer, there may be no treatment of the disease which can prolong the life of the patient or improve the patient's quality of life. In such cases, standard medical advice would be for the caregiver and patient to have conversations with the doctor about the risks and benefits of treatment and to seek options for palliative care or hospice.

During end-of-life care the caregiver can assist in discussions about screening which is no longer necessary. Screenings which would be indicated at other times of life, like colonoscopy, breast cancer screening, prostate cancer screening, bone density screening, and other tests may not be reasonable to have for a person at the end of life who would not take treatment for these conditions and who would only be disturbed to learn they had them. It can be the caregivers place to have conversations about the potential benefits for screenings and to participate in discussions about their usefulness. An example of a need for caregiver intervention is to talk with people on dialysis who cannot have cancer treatment and can have no benefit from cancer screening, but who consider getting the screening.

People with diabetes who use caregiving services, like those in a nursing home, frequently have problems using sliding-scale insulin therapy, which is the use of varying amounts of insulin depending on the person's blood sugar. For people receiving caregiving services, long-acting insulin doses are indicated with varying doses of insulin being the less preferred treatment. If exceptions must be made, then use the long-acting insulin and correct with small doses of sliding scale insulin before the biggest meal of the day.

Advance care planning should note if a patient is using an implantable cardioverter-defibrillator (ICD) and give instructions about the circumstances in which leaving it activated would be contrary to the patient's goals. An ICD is a device designed to prevent cardiac arrhythmia in heart patients. This is a life saving device for people who have a goal to live for a long time, but at the end of life it is recommended that the caregiver discuss deactivating this device with the patient and health care provider. For patients at the end of life, the device rarely prevents death as intended. Using the device at the end of life can cause pain to the patient and distress to anyone who sees the patient experience this.
