The impact of hematology electronic consultations on the management of iron deficiency

Delays in the evaluation and treatment of iron deficiency can lead to increased disease-related morbidity and mortality. Electronic consultation (e-consult) is a referral modality that allows providers quicker access to recommendations from a specialist based on electronic chart review. While the use of e-consult is expanding in classical hematology, gaps exist in the understanding of patient outcomes related to its use for iron deficiency.

We randomly selected 200 e-consults and 200 traditional referrals from 3,336 hematology referrals for iron deficiency at a single center. The primary outcomes of the retrospective analysis were: time to completion of the referral, and time to treatment with intravenous iron. Secondary outcomes included recurrence of iron deficiency, need for repeat e-consult, conversion to in-person evaluation, and assessment of whether the etiology of iron deficiency was addressed.

E-consults significantly reduced the time from referral to intravenous iron repletion (e-consult, 33 days; traditional referral, 68 days; p < .05). Assessment of the underlying etiology occurred in 70.7% of the e-consult encounters compared to 92.5% of traditional referrals (p < .05).

These findings highlight advantages of e-consults in improving care delivery in iron deficiency, and identifying gaps that can be improved through practice standardization to ensure equitable, high-value care.
