Introduction Health systems are seeking innovative solutions to improve specialty care access. Electronic consultations (eConsults) allow specialists to provide formal clinical recommendations to primary care providers (PCPs) based on patient chart review, without a face-to-face visit. Methods We implemented a nephrology eConsult pilot program within a large, academic primary care practice to facilitate timely communication between nephrologists and PCPs. We used primary care referral data to compare wait times and completion rates between traditional referrals and eConsults. We surveyed PCPs to assess satisfaction with the program. Results For traditional nephrology referrals placed during the study period (July 2016–March 2017), there was a 51-day median appointment wait time and a 40.9% referral completion rate. For eConsults, there was a median nephrologist response time of one day and a 100% completion rate; 67.5% of eConsults did not require a subsequent face-to-face specialty appointment. For eConsults that were converted to an in-person visit, the median wait time and completion rate were 40 days and 73.1%, respectively. Compared to traditional referrals placed during the study period, eConsults converted to in-person visits were more likely to be completed (p = 0.001). Survey responses revealed that PCPs were highly satisfied with the program and consider the quick turnaround time as the greatest benefit. Discussion Our eConsult pilot program reduced nephrology wait times and significantly increased referral completion rates. In large integrated health systems, eConsults have considerable potential to improve access to specialty care, reduce unnecessary appointments, and optimize the patient population being seen by specialists.
