Background: Informal caregivers for patients with head and neck cancer perform complex caregiving tasks on a daily basis, but caregivers' needs are rarely acknowledged or addressed in current healthcare practice. Methods: A thorough review of CINAHL®, MEDLINE®/PubMed®, and PsycINFO® was conducted by the authors. 266 manuscripts were identified, with no time limit. The search was conducted in November2019. In total, 19 articles were included in the review. Throughout the disease trajectory, caregivers' psychological and emotional support needs are consistently high, whereas information needs diminish overtime. Implications for practice: Informal caregivers are imperative in supplementing the continuing care demands of people living with head and neck cancer; however, they are at risk for experiencing caregiving burden. Skill training and psychological support interventions are needed for educating and supporting caregivers.
