Clinical Trial Summary
Little is known about eye drop regime adherence in the paediatric population. In particular,
no previous research has investigated this in the paediatric uveitis population, a group who
can require doses up to six times daily, and at frequencies that change month to month. The
aim of the study is to quantify the range of adherence to eye drop medication, and to
investigate some of the reasons for non-compliance in a child specific study. By learning
more about compliance, this will help create treatments that are better suited to children.
The study will recruit 50 children receiving eye drop treatment. After an interval of 1 week
or more the children and their parents will be asked to complete a questionnaire about the
frequency of the drops prescribed, and the frequency that they have used over the last
interval. It will also ask questions about difficulties encountered administering the drops.
Changes in eye drop bottle weight will be measured during the interval and the result
compared.
The information gathered from the questionnaires will be used to compare reports of adherence
between the parent and child, the child's age and the bottle weight. The reasons reported for
difficulties with adherence will also be reported. This is a preliminary investigatory study
to identify whether an issue with medication non-adherence exists. The findings will be used
to tailor further research into this area.
Description:
Purpose This study aims to provide new information about compliance with medications amongst
children and adolescents in an outpatient Ophthalmic setting.
Previous studies have demonstrated in other conditions that adherence to eye drop regimes is
extremely varied (50% to 90% of prescribed drops (Tan 2005)) in a range of paediatric
conditions including myopia, amblyopia, herpes simplex keratitis, allergic conjunctivitis.
There has not been any research into eye drop adherence in the paediatric uveitis population.
Previous enquiries into quality of life in JIA have not included questions about drop
adherence, frequency of flare ups or drop side effects (van Dijkhuizen 2018). Although this
condition is not common, the prevalence of paediatric uveitis is 27.9 per 100,000
(Päivönsalo-Hietanen 2000), it has severe sight threatening complications despite modern
treatment. The burden of disease can be substantial due to eye drops up to six times daily
and weekly appointments during active episodes, as well as surveillance every 3-4 months in
between flares.
There are certain issues that are specific to uveitis which require investigation. These
include the high frequency of steroid drops, changes in frequency on a week by week basis,
and the fact that it is an asymptomatic condition in the early stages. Other studies
reporting drop adherence in the paediatric population are limited because definitions of
adherence and its measurement is inconsistent, and often not the primary outcome of a study.
Parents and clinicians have expressed concerns about how achievable very frequent dosing is.
If a threshold above which eye drop adherence becomes very unreliable exists, for instance
more than four times each day, then clinicans could adjust treatment regimes to reflect this.
This may encourage clinicans to be able to confidently advocate moving on to alternative
therapies, such as biological treatment rather than increasing drop frequency.
By measuring and understanding medication adherence in the paediatric and adolescent
population helps design interventions to improve compliance and assess their success.
Evidence of paediatric specific issues may also lead to the development of age adapted
formulations or trial of existing products in novel ways, for instance slow release steroid
inserts following paediatric cataract surgery (SY Lee 2002).
Design Treatment will not be impacted by the study. There is no randomisation. Compliance may
be impacted by awareness of being involved in a study. This is a major limitation of the
study.
However previous studies have been conducted investigating compliance and their finding have
been held to be valid.
A effort has been made in the design of PIS to provide patients with information about the
study while limiting the impression that their medication compliance is under scrutiny.
Additional vague questions have been added to the questionnaire to obscure the focus of the
questions.
