Objective To analyze the influence of informal caregivers on the functional independence of older adults in the postoperative period of proximal femoral fracture due to falls. Method It is an integrative review of a corpus for analysis that gathered 23 articles, between 2002 and 2012, from databases "Literatura Latino-Americana e do Caribe em Ciências da Saúde" (Latin-American and Caribbean Health Sciences Literature in Health Sciences), Cumulative Index to Nursing and Allied Health Literature, US National Library of Medicine and Scopus. Results There was a predominance of studies by Chinese authors and nurses. The analysis of the studies evidenced that falls followed by fractures lead to dependence of older adults and, consequently, an overload to caregivers. Moreover, older adults and caregivers showed a need for support in the rehabilitation process. Conclusions Informal caregivers still need to be included in care planning and to be qualified for such care by health professionals, since they positively influence functional independence in the postoperative period.
