Complementary and alternative medicine: A survey of its use in children with chronic respiratory illness

BACKGROUND The use of complementary and alternative medicine (CAM) has increased in recent years, with especially high prevalence in individuals with chronic illnesses. In the United States, the prevalence of CAM use in pediatric asthma patients is as high as 89%. OBJECTIVE To investigate the epidemiology of pediatric CAM use in respiratory subspecialty clinics. METHODS A survey was conducted at two hospital-based respiratory clinics in Edmonton (Alberta) and Ottawa (Ontario). Caregivers (most often parents) of children <18 years of age were asked questions regarding child and caregiver use of CAM, including products and practices used, beliefs about CAM, trust in information sources about CAM and characteristics of the respondents themselves. RESULTS A total of 202 survey questionnaires were completed (151 from Edmonton and 51 from Ottawa). Pediatric CAM use in Edmonton was 68% compared with 45% in Ottawa, and was associated with caregiver CAM use, poorer health and health insurance coverage for CAM. The majority (67%) of children using CAM had taken prescription drugs concurrently and 58% of caregivers had discussed this with their doctor. DISCUSSION Lifetime use of CAM at these pediatric clinics was higher than reported for children who do not have chronic diseases. CAM practices that are popular may be worthy of further research to evaluate their effectiveness and safety profile with regard to drug interactions. Health care providers should be encouraged to discuss CAM use at every visit, and explore their patient's health-related beliefs, behaviours and treatment preferences.
