Concomitant use of Western and Chinese medicine treatments in neurosurgical patients in Hong Kong

OBJECTIVE: To investigate the profile of concomitant use of Chinese medicine (CM) and Western medical treatment in neurosurgical patients. METHODS: A guided questionnaire survey was conducted on 309 Chinese patients under neurosurgical care in a teaching hospital in Hong Kong from June to July 2006. RESULTS: Concomitant use of CM was reported by 25.9% of patients. Age was identified to be associated with the use of CM. Half of the CM-users were unaware of there being potential risks of adverse interactions between neurosurgical and CM treatments. Among the CM-users 85% would continue to receive both treatments but only 52.0% would inform neurosurgeons on their CM use. Patients' perceived lack of benefit from CM was the main reason for not using it although 47.0% indicated their willingness to try CM given better access to information. CONCLUSIONS: Informal source was the major channel of CM use amongst patients with neurosurgical conditions. A need for improved patient education and service provision was identified and should become an important consideration for healthcare systems which anticipate an increased use of CM amongst patients. Strategies to enhance doctor-patient communications in mainstream care such as pre-operative checklists for herbal medications and post-operative advice may facilitate the safe and complementary use of both treatment systems.
