†, if any claim within an admission/visit had a diagnosis code for CCA, the entire visit was considered CCA-related; ‡, patients with any of the following medical services during their follow-up period were summarized; patients have varying length of follow up; §, per patient per month HRU was calculated based on the average of the number of admission(s) or visit(s) per patient divided by number of months in each patient’s follow-up; ¶, length of stay for inpatient and ICU admissions were calculated only among patients with at least one inpatient or ICU admission, respectively. CCA, cholangiocarcinoma; HRU, healthcare resource utilization; ICU, intensive care unit; SD, standard deviation.
