Summary

This study piloted a nurse-performed nutritional screening tool (NST) for dialysis patients. While initial reliability was low, modifications show potential for improving early identification of at-risk patients in limited-access settings.

Area of Science:

  • Nephrology
  • Clinical Nutrition
  • Nursing Practice

Background:

  • Hemodialysis (HD) patients face significant risks of nutrition-related complications.
  • Early identification of nutritional issues in HD patients is crucial for timely intervention.
  • Nurses can play a vital role in nutritional screening to address these challenges.

Purpose of the Study:

  • To pilot a novel nurse-performed nutritional screening tool (NST) for hemodialysis patients.
  • To assess the effectiveness of the NST in identifying nutritionally at-risk individuals.
  • To evaluate the potential of the NST in settings with limited access to dietitians.

Main Methods:

  • A 9-parameter NST was developed, including BMI, weight change, appetite, GI symptoms, albumin, pre-dialysis urea, K+, PO4++, and HbA1c.

  • The NST was piloted on 44 hemodialysis patients and results were compared against a Standard Dietitian Assessment (SDA).
  • Statistical analysis included sensitivity, specificity, and Cronbach's alpha for reliability assessment.

    • Main Results:

    • The NST demonstrated a sensitivity of 0.7 and specificity of 0.77 when compared to SDA.
    • Initial reliability (Cronbach's alpha) of the tool was low at 0.18.
    • Removing pre-dialysis urea improved reliability to 0.32, and using only weight loss, appetite, K+, and PO4++ increased it to 0.48.

    Conclusions:

    • The pilot study indicated low reliability for the initial nurse-performed nutritional screening tool (NST) compared to standard dietitian assessment.
    • Further refinement and modification of the NST are necessary to enhance its reliability and clinical utility.
    • The NST shows promise as a supportive tool for nurses in dialysis centers, particularly where dietetic resources are scarce.
