Adherence to treatment in paediatric patients - results of the nationwide survey in Poland.

backgroundDue to high prevalence, non-adherence to prescribed treatment seriously undermines the effectiveness of evidence-based therapies in paediatric patients. In order to change this negative scenario, physicians need to be aware of adherence problem, as well as of possible solutions. Unfortunately, full potential of adherence-targeting interventions is still underused in Poland. Therefore, the aim of this study was to assess the knowledge, attitudes and behaviours toward non-adherence in Polish paediatricians.

methodsAn anonymous cross-sectional nationwide survey was conducted in the convenience sample of Polish doctors providing care to paediatric patients. The survey focused on the prevalence of non-adherence, its causes, and interventions employed. Primary studied parameter was perceived prevalence of non-adherence in paediatric patients. Reporting of this study adheres to STROBE guidelines.

resultsOne thousand and thirty-three responses were eligible for analysis. Vast majority of respondents were female (85.9%), most of them worked in primary care (90.6%). The respondents represented all 16 Polish Voivodeships, with the biggest number coming from the Mazowieckie Voivodeship (n = 144, 13.9%). Survey participants believed that on average 28.9% of paediatric patients were non-adherent to medication. More than half of the respondents (n = 548, 53.0%) were convinced that their own patients were more adherent than average. Duration of the professional practice strongly correlated with a lower perceived prevalence of non-adherence. Professionals with more than 40 years of practice believed that the percentage of non-adherent patients was <=20% particularly often (OR = 3.82 (95% CI 2.11-6.93) versus those up to 10 years in practice). Out of all respondents, they were also most often convinced that their own patients were more adherent than the general population (P < 0.01). Consequently, they underestimated the need for training in this area.

conclusionsPhysicians taking care of Polish paediatric patients underestimated the prevalence of medication non-adherence and believed that this was a problem of other doctors. This optimistic bias was particularly pronounced in older doctors. These results identify important barriers toward improving patient adherence that are worth addressing in the pre- and post-graduate education of Polish physicians. They also put some light over the challenges that educational activities in this area may face.
