"Forewarned and forearmed": Long-term childhood cancer survivors' and parents' information needs and implications for survivorship models of care.

OBJECTIVE: This mixed-method study assessed 1) survivors' and parents' information needs; and 2) associations between unmet information needs and clinical and socio-demographic characteristics.

METHODS: Stage 1: CCS and parents of CCS, >5years post-diagnosis completed a questionnaire on information needs, overall health and perceived risk. Predictors for unmet information needs were assessed by multivariable regression. Stage 2: participants were interviewed in-depth on these topics.

RESULTS: Questionnaires were completed by 485 participants comprising 322 survivors (mean age: 26.7years, SD=7.9; time since diagnosis: 19.7years, SD=8.8) and 163 parents (child age: 12.9years, SD=2.4; time since diagnosis: 9.7years, SD=2.3), and complemented by 70 interviews. Survivors reported unmet information needs about late effects (57.5%) and parents for fertility issues (62.5%). Survivors had more unmet needs for medical information whereas parents had significantly more regarding sexual issues and lifestyle. Being a parent (p=0.001), dissatisfaction with follow-up care (p=0.003), lower overall health (p=0.014), higher perceived risk of late effects (p<0.001), and greater anxiety/depression (p<0.001) were significantly associated with more unmet needs.

CONCLUSION: Unmet information needs were common for survivors and parents of CCS.

PRACTICE IMPLICATIONS: Future efforts towards tailoring information on potential late effects, healthy lifestyles and follow-up care may help to address unmet information needs.
