To improve the care of seniors living with dementia, current initiatives typically target better identification and treatment of the patient. Our recent survey, however, shows we should also focus more on the needs of the informal caregivers who care for this population in primary care settings. This three-round Delphi survey sought caregivers' views on the most frequent and difficult decisions that seniors with dementia, their informal caregivers, and health care providers face in primary care settings in the province of Quebec.
