How essential are in-person clinic visits during maintenance treatment of children with acute lymphoblastic leukemia?

BACKGROUND

Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Treatment consists of an initial intensive phase of chemotherapy, followed by a prolonged period of maintenance chemotherapy intended to reduce the risk of relapse. During the COVID-19 pandemic, the need arose to identify and reduce non-essential hospital visits.

OBJECTIVE

We aimed to determine which proportion of in-person clinic visits during ALL maintenance therapy was associated with a change of management based on the results of the physical examination.

PATIENTS AND

METHODS

Medical records of children receiving maintenance chemotherapy for B-precursor ALL between September 2019 and February 2020 were reviewed. Visits with a new finding on physical examination were divided into those where an in-person assessment was deemed essential versus not essential. Finally, we determined the proportion of essential in-person visits that resulted in a change of management.

RESULTS

A total of 240 maintenance visits by 75 children were analyzed. An abnormal finding on physical examination was noted during 20 visits (8.3%). Of those, 14 (5.8%) uncovered a new finding, six (2.5%) were classified as "in-person visit essential," and among those six visits, three (1.2%) resulted in a change of patient management (one for acute otitis media, one for wheezing, and one for limp).

CONCLUSION

Our findings support the evaluation of care delivery models other than in-person visits during ALL maintenance therapy. A prospective study is required to delineate criteria, benefits/risks, and families' perspectives associated with virtual care delivery and the optimal frequency of in-person visits.
