Surveys of complementary and alternative medicine usage: a scoping study of the paediatric literature.

OBJECTIVE

To conduct a scoping review of paediatric CAM utilisation literature, in order to establish the depth and breadth of the field and identify gaps in knowledge regarding the epidemiology of CAM use.

METHODS

A CAM and paediatric search strategy was developed and run in three databases (Medline, Embase, Amed) in June 2006. It was revised and rerun in February 2010. Utilisation studies about paediatric CAM were selected if they had an English or French abstract. Data were extracted into an excel table by one individual.

RESULTS

152 paediatric CAM utilisation studies were identified as of February 2010, 136 were fulltext English. There was variation in how CAM was defined: vitamins were included in 35 studies, excluded in 12 studies and not mentioned in 40; while prayer was included in 64, excluded in 9, and not mentioned in 39. Over half of the studies identified were from North America. The majority of studies were conducted in conventional health settings. The four most commonly studied subpopulations were cancer, asthma, autistic spectrum disorder, and attention deficit hyperactivity disorder. Eighteen percent of studies did not report on the period of assessment used. Twenty-seven percent of studies inquired about adverse events and 32% inquired about costs and insurance coverage.

CONCLUSION

There are substantial paediatric utilisation data available but some subpopulations remain poorly researched. The need for transparent utilisation data remains important in order to help prioritize safety and efficacy research.
