Plain English Summary
Background and study aims
The majority of dialysis patients are using phosphate binders to prevent or reduce high phosphate blod levels. In this study we want to investigate adherence to, knowledge and beliefs about phosphate binder treatment in dialysis patients. We also want to investigate whether counselling about phosphate binder treatment changes these parameters and the phosphate blod levels.
Who can participate?
Dialysis patients aged 18 years or more, attending the Dialysis centre at Akershus unitversitetssykehus, can participate in the study.
What does the study involve?
All participants in the study will receive a one-to.one pharmacist-led education and counselling session. All participants will answer three questionnaires twice. These include questions about phosphate binders, adherence to phosphate binder treatment and beliefs about phosphate binder treatment.
What are the possible benefits and risks of participating?
The study is assumed to be of potential benefit for the participants by improving their knowledge about phosphate binders and their awareness of the importance of phosphate binder treatment.
There are no risks of participating in the study. Participation includes counselling by a pharmacist about phosphate binder treatment. Participants need to spend a bit of time answering questionnaires, during dialysis.
Where is the study run from?
The study is a cooperation between the Hospital pharmacy and the Dialysis centre at Akershus unversitetssykehus.
When is the study starting and how long is it expected to run for?
The study started in May 2017 and the approximate duration of the trial was two months.
Who is funding the study?
The Hospital Pharmacies Enterprise, South Eastern Norway are paying the costs that the trial will incur.

Interventional study to improve adherence to phosphate binder treatment in dialysis patients
A one-to-one pharmacist-led education and counselling can enhance adherence and lead to changes in serum phosphate in dialysis patients.

Kidney disease requiring dialysis
Patients included in the study received a single half-hour one-to-one pharmacist-led education and personalized counselling session. A semi-structured counselling guide was used in the session. An educational leaflet based on this guide was offered to the included patients.
Primary outcome measure
Change in the proportion of patients with serum phosphate below 1.80 mmol/L. Serum phosphate levels for five months prior to the intervention, and five months after were drawn from the medical records for included patients.
Secondary outcome measures
Change in the patient's knowledge, beliefs and adherence after the intervention measured by completion of questionnaires:
'Medication Adherence Report Scale'
'Beliefs about Medicines Questionnaire'
The participants were asked to answer the questionnaires twice; at the time of inclusion and 3 - 4 weeks after the intervention.
