Determinants of Complementary Medicine Service Utilization in a Regional South Australian Population: A Cross-Sectional Study

Abstract

Purpose: The dearth of accessible and appropriate conventional health care services in regional areas may drive many people to seek care provided by complementary medicine (CM) practitioners. Understanding the drivers of CM service use in this population may help inform future health services planning. This study set out to examine the determinants of CM service utilization in a regional South Australian population. Methods: Adults residing in regional South Australia between April 2017 and March 2018 were invited to complete the 44-item consumer utilization, expectations, and experiences of health care instrument. The questionnaire was available in print and online, and was promoted using a multimodal recruitment campaign. Independent predictors of CM service use were determined using multivariate logistic regression. Findings: Completing the questionnaire were 3,926 adults (56.7% aged 50+ years; 52.5% females). Forty-seven percent of participants reported using a CM service within the last 12 months. Univariate analyses revealed a statistically significant association between 13 factors and CM service use. When these factors were forced into a multivariate logistic regression model, the number of predictors of CM service utilization was reduced to 10, which included 6 predisposing factors, 3 enabling factors, and 1 personal health practice. This model was able to explain 23.1% (Nagelkerke R2 = 0.231) of the variation in CM service use in this sample. Conclusions: A high level of CM service use was reported among participants living in regional South Australia. The findings highlight the degree to which the appropriateness of health services impacts health-seeking behavior in regional communities.
