Summary: | WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT
• Adverse drug reactions (ADRs) in children are common, and although some are serious, studies on this topic are scarce.
• A review of studies published before 2000 showed that the overall incidence of ADRs in hospitalized children was 9.53% (95% CI 6.81, 12.26) and in outpatients 1.46% (95% CI 0.7, 3.03).
WHAT THIS STUDY ADDS
• Information about the occurrence and seriousness of reported ADRs, suspected medications, age and gender of children and type of reporter is only sparsely available in the literature.
• Substantial amounts of information about ADRs occurring in children have been reported to national ADR databases and during chart review of hospitalized children in recent years.
• The ADRs most commonly reported in children were of the types: (i) skin and subcutaneous disorders (range 15–65%); (ii) general disorders and administration site conditions (range 5–70%); (iii) gastrointestinal disorders (range 5–60%); and (iv) nervous system and psychiatric disorders (range 5–45%), mainly reported for the therapeutic groups: vaccines, antibiotics and psychotropic medicines.
• The majority of reported ADRs concerned paediatric populations from North America and Europe.
AIM
To review the literature on adverse drug reactions (ADRs) in children with respect to occurrence, seriousness, type, therapeutic group, age and gender of the child and category of reporter.
METHODS
Medline and Embase databases were searched from origin and updated until February 2010. We included empirically based articles on ADRs in populations aged 0 to 17 years. Studies monitoring ADRs in patients with particular conditions or drug exposure were excluded. We extracted information about types and seriousness of ADRs, therapeutic groups, age and gender of the child and category of reporter. ADR occurrence was calculated as incidence rate and prevalence.
RESULTS
We included 33 studies monitoring ADRs in general paediatric populations. The highest numbers of ADRs were reported in national ADR databases where data were collected over a longer period than in studies monitoring inpatients and outpatients. However, prevalence and incidence were much lower in the national databases. Types of reported ADRs, seriousness of ADRs and types of medicines differed substantially between studies due to differences in time periods and patient populations. Information about ADRs was mainly provided by health care professionals, although parents also contributed r |
