This descriptive qualitative study was conducted to understand supportive care needs from the perspectives of cancer patients and their healthcare providers (HCPs). Data collected from a purposive sample of 15 individuals (eight cancer patients and seven HCPs) using individual semi-structured interviews (60–90 minutes) were analyzed using thematic analysis. Four themes emerged from interview data in both patients and their HCPs: (1) information and resources, (2) peer support groups, (3) support for caregivers, and (4) tailored care. These four themes were discussed with subtle differences between groups. In addition, communication with and among HCPs was discussed by patients, while survivorship was mentioned by HCPs. Findings from this study indicate that nurses and other HCPs should provide supportive care congruent with the needs, preferences, and priorities of cancer patients through active and bidirectional communication with patients as well as interdisciplinary collaboration, which may optimize patient outcomes and use of resources.
