Study on Influential Factors for Medication Compliance of Phosphate Binder in Patients with Maintenance Hemo- dialysis and Pharmaceutical Intervention / 中国药房

ABSTRACT

OBJECTIVE：To study influential factors for medication compliance of phosphate binder in patients with maintenance hemodialysis and the effects of pharmacist intervention ，and to improve medication compliance and the effects of disease control. METHODS ：The patients with maintenance hemodialysis who were treated in the blood purification center of our hospital from Jun. to Dec. ，2019 were selected for questionnaire survey. The questionnaires involved general information ， medication compliance of phosphate binder ，disease and medicine related knowledge ，social support ，self-efficacy. The t-test，χ2 test and multivariate Logistic regression analysis were used to analyze influential factors for medication compliance. The patients were randomly divided into pharmaceutical intervention group and non-intervention group. Intervention group were provided with pharmaceutical care for 3 months according to risk factors. Blood phosphorus level and medication compliance was compared between 2 groups. RESULTS ：Totally 298 patients completed the survey （effective recovery rate of 96.1％）. Among them ，163 patients（54.7％）had good adherence to phosphate binder ，while 135 patients（45.3％）had poor compliance. Results of single factor analysis showed that medication compliance of phosphate binder was closely associated with age ，dialysis duration ， parathyroid hormone levels ，total daily dose ，daily dose of phosphate binder ，disease and medicine related knowledge scores ， social support ，self-efficacy（P＜0.05）. Results of multivariate Logistic regression analysis showed that total daily dose ，daily dose of phosphate binder ，disease and medicine related knowledge scores ，social support and self-efficacy were the influential factors for medication compliance （P＜0.05 or P＜0.01）. Medication compliance ，disease control status ，disease and medicine related knowledge score ， social support and self-efficacy in pharmaceutical intervention group were significant improved ， blood phosphorus level was significant lower ，compared with non-intervention group （P＜0.05）. CONCLUSIONS ：Independent risk factors influencing medication compliance of phosphate binder include total daily dose ，daily dose of phosphate binder ，disease and medicine related knowledge scores ，social support and self-efficacy. The patients with maintenance hemodialysis have poor compliance to phosphate binder. Pharmacists should take individualized and targeted intervention measures for the above risk factors，which can effectively improve the medication compliance and disease prognosis of patients.
