Conventional health care service utilization among cancer survivors that visit traditional and complementary providers in the Tromsø study: a cross-sectional study

BACKGROUND: Traditional and complementary medicine (T&CM) is commonly used among cancer patients worldwide. Cancer patients in Norway mainly visit T&CM providers in addition to conventional health care services. It is not known how their utilization of T&CM providers influences their use of conventional health care services. The aim of this study was to investigate the difference between the utilization of conventional health care services among cancer survivors that visit T&CM providers and those that do not, and their associated factors. METHOD: Health care service utilization data were obtained from cancer survivors 40 years and above participating in the Tromsø Study: Tromsø 7 conducted in 2015–2016. Data were collected from self-administered questionnaires. Pearson chi-square tests, Fisher exact tests, t-test, and logistic regression were used, with the significance level considered at p < 0.05. RESULTS: Of 1553 individuals, 10% (n = 155) reported visiting T&CM providers in the past 12 months. As both cancer survivors visiting and not visiting T&CM providers were frequent users of conventional health care, no significant differences were found in the overall use of conventional health care (98.1vs.94.5%, p = .056). Users of T&CM providers were however more likely to visit physiotherapists (40.1% vs 25%, p < .001), emergency rooms (29.2% vs 16.5%, p < .001), chiropractors (17% vs 6%, p < .001), and psychologist/psychiatrist (8.9% vs 3.4%, p < .001). They also had more frequent visits to conventional health care (11.45 vs 8.31 yearly visits, p = 0.014), particularly to general practitioners (5.21 visits vs. 3.94 visits, p = .002). CONCLUSION: Results from this study show that visits to T&CM providers are associated with more visits to conventional health care services among cancer survivors. Further studies are needed to investigate the reasons for this high use behavior.
