Problem Identification: Uncertainty is a major source of distress for cancer survivors. Because cancer is primarily a disease of older adults, a comprehensive understanding of the antecedents and outcomes of uncertainty in older adults with cancer is essential.
Literature Search: MEDLINE®, PsycINFO®, Scopus, and CINAHL® were searched from inception to December 2015. Medical Subject Headings (MeSH) terms and free text words were used for the search concepts, including neoplasms, uncertainty, and aging.
Data Evaluation: Extracted data included research aims; research design or analysis approach; sample size; mean age; type, stage, and duration of cancer; type and duration of treatment; uncertainty scale; and major results.
Synthesis: Of 2,584 articles initially identified, 44 studies (30 qualitative, 12 quantitative, and 2 mixed-methods) were included. Evidence tables were developed to organize quantitative and qualitative data. Descriptive numeric and thematic analyses were used to analyze quantitative results and qualitative findings, respectively. Outcomes were reported under four main categories: antecedents of uncertainty, outcomes of uncertainty, management of uncertainty, and the experience of uncertainty.
Conclusions: Uncertainty is an enduring and common experience in cancer survivorship. Uncertainty is affected by a number of demographic and clinical factors and affects quality of life (QOL) and psychological well-being.
Implications for Practice: Uncertainty should be considered a contributing factor to psychological well-being and QOL in older adults with cancer. Nurses are in a unique position to assess negative effects of uncertainty and manage these consequences by providing patients with information and emotional support.
