Objectives To assess knowledge deficits of patients/parents and prevention strategies.
Methods After receiving ethics approval, we performed a controlled, quasi-randomised, prospective intervention study. We enrolled patients/parents involved in managing oral medicines in three groups: control (routine care only), handbook intervention and pharmaceutical counselling intervention group. At baseline and after the interventions, we assessed patients’/parents’ knowledge deficits (incorrect or missing answers) by questionnaire.
Results We enrolled 64 patients/parents. At baseline, knowledge deficits among the groups were similar: 17% in controls, 22% in the handbook group and 24% in the pharmaceutical counselling group. After the intervention, knowledge deficits decreased to 13% in the handbook group and to 8% in the pharmaceutical counselling group (NS; p=0.003 compared with controls, respectively). For controls, knowledge deficits remained almost unchanged (19%). Results for the pharmaceutical counselling group showed a strong correlation between baseline knowledge deficits and the extent of the deficit decrease after the intervention (τ=−0.74; p<0.001), whereas no significant correlation was found in the control or handbook group.
Conclusions In paediatric oncology, patients’/parents’ knowledge of managing oral medicines was improved. Pharmaceutical counselling substantially reduced high knowledge deficits but no significant improvement was seen with the handbook approach. Pharmaceutical counselling should be offered to patients/parents with high knowledge deficits to reduce errors in managing medicines and increase safety.
