Adverse events associated with the use of complementary and alternative medicine in children.

OBJECTIVE: To determine the types of adverse events associated with the use of complementary and alternative medicine (CAM) that come to the attention of Australian paediatricians. DESIGN: Monthly active surveillance study of CAM-associated adverse events as reported to the Australian Paediatric Surveillance Unit between January 2001 and December 2003. RESULTS: There were 39 reports of adverse events associated with CAM use, including four reported deaths. Reports highlighted several areas of concern, including the risks associated with failure to use conventional medicine, the risks related to medication changes made by CAM practitioners and the significant dangers of dietary restriction. The reported deaths were associated with a failure to use conventional medicine in favour of a CAM therapy. CONCLUSION: CAM use has the potential to cause significant morbidity and fatal adverse outcomes. The diversity of CAM therapies and their associated adverse events demonstrate the difficulty addressing this area and the importance of establishing mechanisms by which adverse effects may be reported or monitored.

A cross-sectional survey of complementary and alternative medicine use by children and adolescents attending the University Hospital of Wales.

BACKGROUND: A high prevalence of CAM use has been documented worldwide in children and adolescents with chronic illnesses. Only a small number of studies, however, have been conducted in the United Kingdom. The primary aim of this study was to examine the use of CAM by children and adolescents with a wide spectrum of acute and chronic medical problems in a tertiary children's hospital in Wales. METHODS: Structured personal interviews of 100 inpatients and 400 outpatients were conducted over a 2-month period in 2004. The yearly and monthly prevalence of CAM use were assessed and divided into medicinal and non-medicinal therapies. This use was correlated with socio-demographic factors. RESULTS: There were 580 patients approached to attain 500 completed questionnaires. The use of at least one type of CAM in the past year was 41% (95% CI 37-46%) and past month 26% (95% CI 23-30%). The yearly prevalence of medicinal CAM was 38% and non-medicinal 12%. The users were more likely to have parents that were tertiary educated (mother: OR = 2.3, 95%CI 1.6-3.3) and a higher family income (Pearson chi-square for trend = 14.3, p < 0.001). The most common medicinal types of CAM were non-prescribed vitamins and minerals (23%) and herbal therapies (10%). Aromatherapy (5%) and reflexology (3%) were the most prevalent non-medicinal CAMs. None of the inpatient medical records documented CAM use in the past month. Fifty-two percent of medicinal and 38% of non-medicinal CAM users felt their doctor did not need to know about CAM use. Sixty-six percent of CAM users did not disclose the fact to their doctor. Three percent of all participants were using herbs and prescription medicines concurrently. CONCLUSION: There is a high prevalence of CAM use in our study population. Paediatricians need to ensure that they ask parents and older children about their CAM usage and advise caution with regard to potential interactions.CAM is a rapidly expanding industry that requires further evidence-based research to provide more information on the effectiveness and safety of many CAM therapies. Statutory or self-regulation of the different segments of the industry is important. Integration of CAM with allopathic western medicine through education and better communication is slowly progressing.

Survey of complementary and alternative medicine use at a tertiary children's hospital.

OBJECTIVE: The use of complementary and alternative medicine (CAM) within the Australian community is common. The objective of this study was to determine the prevalence and pattern of CAM usage in children attending a tertiary children's hospital. METHODS: We conducted a cross-sectional survey of children attending the Royal Children's Hospital, Melbourne. Children were identified by consecutive acute admissions and attendance at outpatient clinics. A structured questionnaire with items about the use of CAM in the preceding year was administered by means of a face-to-face interview. RESULTS: Based on the 503 children surveyed, 51% reported CAM use in the preceding year. Forty-three percent had used at least one CAM medication. The most common medicinal CAM used were multivitamins, vitamin C, herbal remedies and homeopathic treatments. Non-medicinal CAM was used by 23% of the participants. The most commonly used therapies were chiropractic, naturopathy, aromatherapy, therapeutic massage and dietary restriction. The main reasons stated for CAM usage included promotion of general health and treatment of colds. Sixty-three percent of those reporting CAM use had not discussed this with their treating doctor. CONCLUSION: The use of CAM by children is common. Complementary and alternative medicine is particularly used for the treatment of common illnesses and conditions of childhood. Importantly, use is not always conveyed to treating physicians. Given the potential risk of adverse events associated with the use of CAM or interactions with conventional management, doctors should ask about their use as a part of routine history taking.
