Feasibility of nephrology electronic consults in an inner-city population.

BACKGROUND

In the United States (U.S.), economically disadvantaged populations have reduced access to subspecialty care. To improve accessibility to nephrology care early in the clinical course of chronic kidney disease (CKD), we designed a feasibility pilot study for electronic consults (eCons).

MATERIALS AND

METHODS

This retrospective cohort study evaluated eCons referral patterns, patient demographics, comorbidities, and rates of in-person visits following eCons. Our suggested referral criteria included CKD stages 1 - 3a with a urine albumin-creatinine ratio (UACR) < 300 mg/g, resistant hypertension, abnormal kidney imaging or urine sediment, electrolyte abnormalities, and nephrolithiasis.

RESULTS

A total of 103 patients completed eCons over a 12-month period. 98% self-identified as African Americans, and 2% as Caucasians. The rates of subsequent in-person visits for patients with CKD stages 2, 3a, 3b, 4, and 5 were 5/9 (56%), 8/28 (29%), 34/38 (90%), 11/14 (79%), and 9/9 (100%), respectively. Among the 103 patients, 40 (39%) had macroalbuminuria (UACR > 300 mg/g), and 51 (50%) had diabetes mellitus. The rates of subsequent in-person visits for patients with macroalbuminuria and diabetes mellitus were 87.5% and 76%, respectively. Patients with macroalbuminuria had greater odds of subsequent in-person visits than did those without macroalbuminuria, adjusted for age and sex (AOR, 6.15; 95% confidence interval (CI), 2.08 - 18.16; p = 0.001). Patients with diabetes mellitus were also more likely to have subsequent in-person visits than were those without diabetes mellitus (OR, 2.38; 95% CI, 1.02 - 5.57; p = 0.04).

CONCLUSION

Electronic consultations are beneficial in the early CKD stages and in patients without diabetes or macroalbuminuria. In addition, both macroalbuminuria and diabetes influence the need for subsequent in-person evaluation.
