In this study, evidence is provided for supporting siblings as a standard of care in pediatric oncology. Using Medline, PsycInfo, and CINAHL, a systematic search of articles published over the past two decades about siblings of children with cancer was conducted. A total of 125 articles, which were primarily descriptive studies, were evaluated by the four investigators using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. There is moderate-quality evidence, as well as support from community stakeholders, to justify a strong recommendation that siblings of children with cancer should be provided with psychosocial services and that parents and professionals are advised about how to meet siblings' needs.

INTRODUCTIONSiblings are exposed to significant stress when a child is diagnosed with cancer. Concern about the ill child, disruptions in family roles and routines, decreased contact with family members, and additional demands for caregiving or other responsibilities in the home are common. [1,2] In some cases, siblings are also called upon to serve as a donor for stem cell transplant, which can introduce other ethical and psychosocial concerns. [3] Taken together, these unique challenges leave siblings of children with cancer at risk for acute and long-term psychosocial difficulties. However, there are no current evidence-based standards for the supportive care of siblings of children with cancer.Although severe psychopathology is rare, several reviews suggest that some siblings exhibit symptoms of anxiety, depression, posttraumatic stress; lower quality of life and healthcare utilization; and disruption to academic and social functioning. [1,2,4,5] Most difficulties improve over the first year after diagnosis, but they may resurface or worsen with declines in the ill child's health or death.[6] Siblings can also demonstrate resilient outcomes, such as posttraumatic growth. [4,7] This variability in adjustment underscores the need for accurate screening to identify risk and protective factors and to provide appropriate services for siblings vulnerable to difficulties. Unfortunately, siblings have unmet needs and psychosocial support may be limited. [8,9] Further, in a large survey of professionals from three pediatric oncology organizations, only 25% reported that they provide psychosocial services to siblings.[10] Thus, it is critically important to establish evidence-based standards of care for siblings of children with cancer in efforts to encourage the provision of more consistent and comprehensive services for this population.
METHODSThis review was performed as a part of the collaborative effort, Standards for Psychosocial Care of Children with Cancer and Their Families. A full description of the methods used to develop each standard is in the introduction to this special issue.[11] The literature search for this standard used three ...
