An evidence-based nurse-led fluid and dietary control program for haemodialysis patient

Abstract

End stage renal failure refers to an irreversible kidney dysfunction in which the kidneys fail to remove toxins from the blood stream. Haemodialysis is an effective treatment modality to sustain the lives of patients with end stage renal failure by removing waste products like urea, creatinine, and excess fluid. It involves a challenging regimen including dietary restrictions to ensure long-term survival. Failure to adhere with the regimen can result in fatal consequences.

Renal patient discomfort related to non-adherence is commonly seen in clinical settings; however, there is currently no evidence-based fluid or dietary education program available to haemodialysis patients. This dissertation aims to identify and evaluate current evidence for the effectiveness of dietary and fluid control programs in the treatment of haemodialysis patients, to assess the transferability and feasibility of implementing a nurse-led education program regarding dietary and fluid control in haemodialysis patients, and to develop an evidence-based, nurse-led fluid and dietary control program for haemodialysis patients.

Four electronic bibliographical databases including PubMed, Cochrane library, PsycInfo and CINAHL and two searching engines including Google scholar and ProQuest were used to identify studies that examined the effectiveness of educational programs or interventions on fluid or dietary control for patients on haemodialysis. Forty-five unique studies were identified as potentially relevant. Eleven of those studies met the selection criteria and were evaluated in this dissertation. Appraisal instrument was used to evaluate the quality of the selected studies. Six studies and three studies showed statistically significant in reduction of serum phosphate level and interdialytic weight gain respectively after educational intervention. Critical evaluation of the available studies led to an evidence-based, nurse-led, fluid and dietary control program for haemodialysis patients that followed the guideline development process of the Scottish Intercollegiate Guideline Network.

Comparison on the similarity of patient characteristics, staff competence, and organizational settings of the evaluated studies were similar to those of the target unit. Therefore, the proposed program may be transferable and feasible. Furthermore, a cost-benefit analysis showed that the benefit of the fluid and dietary control program to patients outweighs the cost needed to implement the program.

This dissertation outlines a proposed twenty-week program including marketing of the program, training of staff in the targeted renal unit, pilot testing, and application of the proposed program. Evaluation of the program will focus on three categories: patient outcome, health care provider outcome, and organization outcome. Clinical effectiveness of the program is defined by an overall reduction in patients’ mean interdialytic weight gain and mean serum phosphate level, improvement in knowledge test scores by patients, satisfactory nurses’ attendance rate in the renal training sessions, high nurse satisfaction with the educational program, and reduction of admission rate related to non-adherence.
