Hyperphosphatemia in patients undergoing haemodialysis treatments is associated with major health problems. This situation is often associated with non-adherence to treatment.

Authors highlight the need of implementing measures to overcome obstacles on adherence to the treatment.

The lack of knowledge is considered the main obstacle for non-adherence to therapy, therefore, training patients is one of the solutions.

The authors address this issue on two different and dissociated perspectives: pharmacological or nutritional. Therefore we need a interdisciplinary approach that includes these two perspectives.

Introduction


To analyse the relation between phosphorus levels and

adherence to drug therapy and nutrition recommendations;

To assess the impact of a interdisciplinary education program

on phosphorus levels and treatment adherence.

Objectives


Methods

Inclusion criteria:

- Patients who were taking phosphate binders in the beginning of the study (OsvaRen®, Phosphosorb®, Renvela®);

- Patients on Haemodialysis program for at least 4 months;

- Non-institutionalized patients;

- Patients with cognitive ability;

- Patients with an average of phosphorus levels > 3.5 mg/dl over the last 3 months;

This is a quantitative, descriptive, correlational and analytical study

that consists on the implementation of a interdisciplinary education

program for three months.


Methods

n= 45 patients

n= 48 patients Dropouts: (3 Patients)

- 1 Patient hospitalized

- 2 Patients refused

N= 164 patients

Inclusion criteria


Methods

n= 45 patients

Group A n = 17

Phosphorus levels between 3.5 and

5 mg/dl on average over the

last 3 months

Out of the education program

Group B

n = 17

Phosphorus levels between 3.5 and

5 mg/dl on average over the

last 3 months

In the education program

Group C n = 11

Phosphorus levels higher 5 mg/dl over the last 3

months

In the education program


Methods

1st Stage

• Initial assessment of the treatment adherence of patients in

groups A , B and C.

• Adherence to medication was assessed by Measure Treatment

Adherence scale.

• Adherence to nutritional recommendations was assessed through a

questionnaire of knowledge and attitudes about nutrition and food

intake record.


Methods

2nd Stage

- Application of a interdisciplinary education program in groups B

and C, for 3 months.

- This program includes the nutritional and pharmacological

perspective:

Through a group session and two individualized training sessions about

nutrition.

Three individualized training sessions about phosphate binders.

3rd Stage

- Assessment of the patients’ treatment adherence in groups A, B and C after the education program.

- Application of the Measure Treatment Adherence Scale and questionnaire of knowledge and attitudes about nutrition and food intake.

- Analysis of the average of phosphorus levels of the three months during and after the education program in group A, B and C.

Analysis of the impact of the education program based on average of the first 3 Months after the Education

Program´s beginning.

p=0,494


• Preliminary results show that the education program:

- Increased adherence to phosphate binders, but…

- Was not efficient on improving the phosphorus levels as

expected

Is better adherence to phosphate binders associated to

less concern with nutritional behaviors??
