A qualitative investigation of the perceptions of complementary and alternative medicine among adults in Hawaiʻi

BACKGROUND: Complementary and alternative medicine (CAM) is defined as a group of diverse medical and healthcare practices outside of conventional medicine modalities. The use of CAM is steadily increasing despite gaps in the scientific evidence supporting its use and the challenges of its regulation and integration into conventional healthcare practices. In this context, perceptions concerning CAM become important. The purpose of this study is to identify the perceptions of CAM among adult residents of Hawaiʻi. METHODS: Two researchers conducted audio-recorded interviews at the University of Hawaiʻi Mānoa (UHM) campus. Participants were over the age of 18, spoke English fluently, and self-identified as Hawaiʻi residents. Interviews were conducted to the point of data saturation and audio recordings were transcribed verbatim. Researchers collaboratively developed a codebook and used NVivo 12 to analyze transcripts. New codes were added as required. Inter-rater reliability was determined by calculating Cohen’s kappa coefficient. Key themes were identified by both researchers individually and then discussed and evaluated together. RESULTS: Participants were mostly female, white, and affiliated with UHM. Perceptions were categorized as positive, negative, and neutral. The majority of participants had positive perceptions of CAM with few reporting negative perceptions. The positive perceptions were related to CAM’s perceived effectiveness, the desirability of CAM compared to conventional medicine, and CAM’s ability to foster well-being. Negative perceptions were attributed to the lack of scientific evidence and ineffective outcomes of CAM use. Neutral perceptions of CAM related to its safety and natural characteristics. CONCLUSIONS: The study found mainly positive perceptions of CAM among Hawaiʻi residents. Use of CAM is on the rise despite CAM lacking robust empirical evidence demonstrating efficacy across various medical conditions. With insufficient data and understanding of current medical literature, CAM users place themselves at risk for harmful herb-herb and herb-drug interactions. These findings have implications for healthcare providers of both conventional medicine and CAM traditions.
