Supplementary Material for: Diagnosis and Treatment of Patients Utilizing Complementary Medicine at a Tertiary Referral Hospital in Eastern Switzerland

Background In 2012, the Cantonal Hospital of St. Gallen, a tertiary referral hospital in Eastern Switzerland, opened its Center for Integrative Medicine (ZIM). This study aims to characterize disease and treatment characteristics of adult patients treated at the ZIM. Patients and Methods For all new patients physicians at the ZIM completed questionnaires on patients’ diagnoses and treatments. Descriptive statistics for categorical variables were reported as percentages. Univariable logistic regression analysis was used to assess the data. The analysis was performed with the statistical software package SPSS (IBM). Results From 2015 until 2020, 4’592 new patients were seen at the ZIM. The most common diagnosis in the supergroups was cancer (48%), followed by pain diagnoses (33%). Chronic pain as a subgroup was represented the most in patients (29%). Anthroposophical medication was the most commonly prescribed therapy, in 74% of patients with cancer and 73% with pain diagnosis. The latter was associated with the prescription of eurythmy therapy (OR 3.80, p<0.001), traditional Chinese medicine (OR 3.34, p<0.001) or art therapy (OR 5.15, p<0.001), whereas mistletoe therapy was the preferred treatment option (OR 59.0, p<0.001) for a cancer diagnosis. Conclusion and Outlook The results will help to adapt CM services to patients’ needs and provide a good basis for the planning of future services in CM in major hospitals. Further research should be conducted focusing on specific health outcomes.
