Best Approach to Managing Patients with Kidney Diseases in an Interactive Nephrology Exam Setting

The best approach to managing patients with kidney diseases in an interactive nephrology exam setting is to implement an interdisciplinary care model with clear referral thresholds based on disease severity, while focusing on individualized symptom assessment and management to optimize patient outcomes. 1

Referral Criteria and Care Coordination

• Refer patients to specialist kidney care services when eGFR <30 mL/min/1.73 m² (CKD stages G4-G5), as these patients benefit most from nephrology expertise 1
• Consider referral for patients with persistent proteinuria >1 g/day (ACR ≥60 mg/mmol or PCR ≥100 mg/mmol), as these patients may require renal biopsy and potential immunosuppressive therapy 1
• Implement risk prediction models to optimize triage of patients at high risk of kidney failure to specialty care for shared or subsequent care 1
• Refer patients with abrupt sustained decrease in eGFR >20% after excluding reversible causes, or if features suggest diagnosis other than prerenal azotemia or acute tubular necrosis 1
• Consider collaborative care approaches between primary care and nephrology for early CKD stages to mitigate disease progression upstream 1

Symptom Assessment and Management

• Incorporate regular symptom screening into clinical practice, focusing on symptoms most important to patients 1
• Use open-ended questions to facilitate dialogue: "How are you feeling?", "What is bothering you most?", "Has anything changed?" 1
• Acknowledge symptoms even when treatment options are limited, as feeling heard and understood is therapeutic for patients with life-limiting illness 1
• Ensure symptom assessment takes into consideration biological, psychological, and social factors surrounding the patient 1

Early Identification and Intervention

• Implement lifestyle modifications as a cornerstone of CKD management, including smoking cessation, regular exercise, and healthy diet (fruits, vegetables, legumes, whole grains) 1
• Accurately diagnose and stage CKD to guide treatment choices, medication dosing, and nephrotoxin avoidance 1
• Use ACE inhibitors/ARBs as first-line agents in those with albuminuria, even in the absence of hypertension 1
• Monitor for ACE inhibitor side effects, including hyperkalemia, which occurs in approximately 2.2% of hypertensive patients and 4.8% of heart failure patients 2
• Be cautious with ACE inhibitors in elderly patients, as pharmacokinetic studies indicate maximum blood levels and AUC are doubled in older patients 2

Alternative Care Delivery Models

• Consider nontraditional modes of nephrology care delivery such as e-consults and telenephrology to improve access to specialty care 1
• Utilize interactive educational interventions that include both individual and group participation to improve knowledge and self-management for secondary prevention of CKD 1
• Address barriers to patient education including inappropriate literacy levels, poor access to multidisciplinary teams, or lack of health system preparedness 1

Common Pitfalls and Caveats

• Avoid labeling patients with isolated low eGFR (especially G3a) without associated markers of kidney damage as having CKD, as this can cause insurance problems 1
• Recognize that the vast majority of patients with stage 3 CKD do not progress to ESRD but die mainly from cardiovascular causes; primary care intervention for cardiovascular risk reduction should be strongly considered 1
• Be aware that rare kidney diseases account for only 5-10% of people with CKD but constitute more than 25% of patients receiving kidney replacement therapy, highlighting their importance in nephrology practice 3
• Remember that medication dosing requires careful consideration in CKD patients to avoid toxicity, particularly with gabapentinoids and baclofen which can cause sedation and encephalopathy in advanced CKD 1

Educational Approaches for Interactive Settings

• Use objective structured clinical examinations (OSCEs) for formative assessment of clinical skills, particularly for specialized areas like home hemodialysis where clinical exposure may be limited 4
• Implement case-oriented questions with audience response systems to test knowledge and judgment in real-time, similar to the American Society of Nephrology's annual Nephrology Quiz and Questionnaire 5
• Focus educational efforts on evidence-based/standard-of-care questions, as these areas often show knowledge gaps even among nephrology fellows 4
