The use of complementary and alternative therapies in people with chronic diseases is an under-researched area, despite the fact that these therapies can interact with mainstream health treatment, such as prescription medicines. The latest column from PHCRIS (the Primary Health Care Research and Information Service) outlines the findings of a new study into complementary and alternative medicine use among people in a regional South Australian community.

Jodie Oliver-Baxter writes: 
Lessening the burden of chronic disease is a growing concern at individual, community, national and global levels.

There is some evidence that Complementary and alternative medicine (CAM) use is higher for people with a chronic disease.

CAM is commonly divided into two categories based on the modalities employed – medication-based (e.g., multivitamins) or procedure-based (e.g., massage,) manual therapies. In addition the scientific evidence for most CAM use is limited.

The authors of this study acknowledge that understanding the prevalence of CAM use in this regional population is vital because people managing chronic disease are more likely to require multiple prescription medications, thus increasing the potential for adverse drug-herbal medicine interactions.

There was also concern that studies conducted elsewhere may not be generalisable to the Australian rural/regional context.

This project sought to explore biological, psychosocial and environmental determinants of chronic health conditions (N = 1138). Participants were based in regional South Australia.

Findings indicate the prevalence of CAM use in this regional community was slightly lower (~30%) than in other rural communities outside of South Australia. CAM service users had a higher socioeconomic status than non-users, but CAM supplement users were not different socioeconomically from their counterparts.

Similar to previous research, multivitamin supplements, fish oil and glucosamine were the most frequently reported CAM consumed.

Critically, this study limited CAM services to the three categories – chiropractors, alternative therapists, and massage therapists.

In addition there may have been misclassification of CAM medicine use as this relied on the participants determining their reason for taking the medication. For example CAM can be taken to treat a disease, to treat symptoms or side-effects of treatment and for prevention.

This study identified that although participants who used CAM were no more likely to have a chronic disease, they were more likely to be higher users of the mainstream health system, and taking prescription medications.

This finding has particular relevance for consumers and practitioners, as authors reiterate, there are risks associated with combined mainstream and CAM use.
