Objectives: Side effects from the prolonged use of gonadotropin-releasing hormone (GnRH) agonists may lead to nonadherence to the treatment in men with advanced prostate cancer (PCa). We investigated the reasons contributing to nonadherence to GnRH agonists through interviews with men with PCa and focus groups with their health care professionals.
Data sources: The three stages of the study were validation of themes, interviews with men on GnRH agonists, and focus groups with oncology specialists and clinical nurse specialists. An experienced oncologist validated factors contributing to nonadherence identified from the literature. A total of 10 men with PCa were recruited from a large teaching hospital and were interviewed on a one-to-one basis using a topic guide. In stage three, two separate focus groups were held with oncology specialists and clinical nurse specialists treating men with PCa. The interviews and focus groups were audio recorded and transcribed verbatim. Initial codes identified from stage three were grouped into themes and thematically analyzed.
Conclusion: Themes identified from the interviews and focus groups influencing adherence to treatment were side effects of treatment, patient belief system, benefits outweigh harm, quality of life over quantity of life, social support, and patient-clinician relationship. Although side effects such as hot flushes and loss of libido were sometimes overwhelming for many, these men felt that treatment benefits outweighed harm.
Implications for nursing practice: Reasons leading to nonadherence can be multifactorial and unique to each patient. Employing different strategies by health care professionals may lead to the eventual acceptance of treatment, while also acknowledging their reasons for nonadherence.
