Of the 16 patients, 7 had matched short- and standard-interval data, whereas the remaining 9 were treated with only short-interval pain plans. All patients received their primary hematologic care at the Penn Comprehensive Sickle Cell Program (CSCP) and received treatment for VOEs at the Hematology-Oncology Evaluation Center (OEC) at the Hospital of the University of Pennsylvania. The average number of infusion center visits per month were calculated for each patient in the standard-interval time frame (1 March 2020 to 31 December 2020; 10 mo) vs the short-interval time frame (1 January 2021 to 31 August 2021; 8 mo).
