A Qualitative Exploration of Medication Experience and Factors Contributing to Adherence to Oral-Targeted Therapy Among Lung Cancer Survivors.

OBJECTIVES

The introduction of oral-targeted therapy for cancer improves survival while adherence also presents as a challenge to patients. Current studies on oral anticancer agents are primarily limited to patients from developed countries with breast cancer and chronic myeloid leukemia receiving oral chemotherapy and hormonal therapy. This study explored experience of oral-targeted therapy adherence among Chinese patients with nonsmall cell lung cancer and its contributing factors by using a qualitative research.

DATA SOURCES: Semi-structured interviews with 16 patients and 7 family caregivers at a tertiary tumor hospital in China were conducted to understand their experience and perceptions of oral-targeted therapy. Thematic analysis was applied to generate the themes and to identify underlying factors associated with the adherence.

CONCLUSION

The lung cancer survivors struggled with ambivalence between survival and relief during taking targeted anticancer medication and showed diverse models of nonadherence, including intentionally or unintentionally intermittent medication and overadherence. Three main themes were identified: (1) cancer-related distresses, (2) inadequate social support, and (3) forgetfulness, together with seven subthemes, representing factors impeding patients' medication adherence. The themes demonstrate complicated and interrelated factors from personal, interpersonal, sociocultural, and structural forces contributing to patients' poor adherence.

IMPLICATIONS FOR NURSING PRACTICE: The findings suggest the imperativeness of reinforcing community- or home-based oral-targeted medication management in which nurses play a principal role to implement strategies of patient education, symptom management, reminder prompts, and monitoring to improve adherence.
