Barriers to medication adherence among adolescents and young adults with cancer.

BACKGROUND: Adherence promotion is a critical component of adolescent and young adult (AYA) cancer care, but predictors of nonadherence that could be targeted in intervention efforts remain largely unknown. The purpose of this multi-site longitudinal observational study was to examine the relationship between barriers and medication adherence among AYAs with cancer. PROCEDURE: Sixty-five AYAs (ages 15-24 years; mean age = 18.97 years, SD = 2.51; Mmean time since diagnosis = 1.42 years, SD = 1.95) with newly diagnosed or relapsed cancer completed self-report measures of barriers and adherence at quarterly study visits and used an electronic adherence monitoring device for 12 months. Longitudinal mixed effects models were used to examine our primary hypothesis that greater barriers are related to lower adherence over time. Descriptive statistics were used to explore our secondary aim of describing the frequency and patterns of barriers endorsed by AYAs with cancer. RESULTS: After controlling for covariates (time, medication type, race, ethnicity, diagnosis, time since diagnosis), a greater number of barriers was associated with lower electronically monitored (ß = -5.99, p = .005) and self-reported (ß = -1.92, p < .001) adherence. The specific barriers endorsed by AYAs differed across participants, and the majority of AYAs endorsed an entirely different pattern of barriers than any other AYA in the study. CONCLUSION: Barriers are associated with nonadherence and may be a promising target for intervention. Individual variability across barriers, however, suggests that tailoring may be necessary, and a promising next step is to explore personalized approaches to adherence promotion.

Recollection of Fertility Discussion in Adolescent and Young Adult Oncology Patients: A Single-Institution Study.

Purpose: With increasing number of childhood cancer survivors, focus has recently shifted to improving future quality of life and long-term complications, such as infertility. Despite national guidelines, fertility preservation is discussed in less than half of the eligible patients. In this study, we sought to discover if education gaps regarding fertility exist within our practice, in efforts to address these gaps to improve the quality of cancer care we provide. Methods: A retrospective electronic survey was administered to eligible adolescent and young adult oncology patients. Results: Of the 63 patients approached, 47 responded to the survey. Before initiation of antineoplastic therapy, 22/47 (46.8%) stated that they were concerned about their fertility to some degree; however, only 11/47 (23.4%) report pursuing fertility preservation. When asked why they decided against steps to preserve fertility, 15/36 (41.6%) reported that they did not know they had options. Of all patients that completed the survey, 28/47 (59.6%) requested additional information regarding their fertility. Conclusion: Majority of respondents recall having a discussion regarding the impact of antineoplastic therapy on their fertility at the time of diagnosis, which was initiated by their oncologist. However, less than half reported satisfaction with these discussions. Although this study did not demonstrate statistical significance, it has resulted in development of a multidisciplinary oncofertility team for fertility preservation referrals, at our institution, as well as education materials for all newly diagnosed oncology patients.
