Pilot Study of a Physician-Delivered Education Tool to Increase Patient Knowledge About CKD

Background: Limited research exists on physician-delivered education interventions. We examined the feasibility and impact of an educational tool on facilitating physician-patient kidney disease communication. Study Design: Pilot feasibility clinical trial with a historical control to examine effect size on patient knowledge and structured questions to elicit physician and patient feedback. Setting & Participants: Adults with chronic kidney disease (CKD) stages 1-5, seen in nephrology clinic. Intervention: 1-page educational worksheet, reviewed by physicians with patients. Outcomes: Kidney knowledge between patient groups and provider/patient feedback. Measurements: Patient kidney knowledge was measured using a previously validated questionnaire compared between patients receiving the intervention (April to October 2010) and a historical cohort (April to October 2009). Provider input was obtained using structured interviews. Patient input was obtained through survey questions. Patient characteristics were abstracted from the medical record. Results: 556 patients were included, with 401 patients in the historical cohort and 155 receiving the intervention. Mean age was 57 +/- 16 (SD) years, with 53% men, 81% whites, and 78% with CKD stages 3-5. Compared with the historical cohort, patients receiving the intervention had higher adjusted odds of knowing they had CKD (adjusted OR, 2.20; 95% CI, 1.16-4.17; P = 0.02), knowing their kidney function (adjusted OR, 2.25; 95% CI, 1.27-3.97; P = 0.005), and knowing their stage of CKD (adjusted OR, 3.22; 95% CI, 1.49-6.92; P = 0.003). Physicians found the intervention tool easy and feasible to integrate into practice and 98% of patients who received the intervention recommended it for future use. Limitations: Study design did not randomly assign patients for comparison and enrollment was performed in clinics at one center. Conclusions: In this pilot study, a physician-delivered education intervention was feasible to use in practice and was associated with higher patient kidney disease knowledge. Further examination of physician-delivered education interventions for increasing patient disease understanding should be tested through randomized trials. Am J Kidney Dis.62(1): 23-32.
