<p><strong>BACKGROUND: </strong>High-dose chemotherapy with autologous stem cell rescue (HDC-ASCR) has improved event-free survival for children with high-risk neuroblastoma. Common regimens include carboplatin/etoposide/melphalan (CEM), busulfan/melphalan (BuMel), and tandem HDC-ASCR [thiotepa/cyclophosphamide (TC) followed by CEM]. To complement clinical trial data and to evaluate the clinical burden associated with these regimens, resource ultilization (RU) was evaluated. An administrative database was used to evaluate RU in a previously developed high-risk neuroblastoma cohort. Single CEM and BuMel patients were followed for 60&nbsp;days from the first day of the HDC-ASCR preparative regimen or until death, whichever came first. Tandem patients were followed from the first day of the first HDC-ASCR preparative regimen through day 60 from the first day of the second HDC-ASCR. Resources compared included inpatient days, ICU-level care, and medications administered.</p>

<p><strong>RESULTS: </strong>A cohort of 578 patients was evaluated; 422 patients underwent single HDC-ASCR with CEM, 67 received BuMel, 72 underwent TC/CEM, and 17 received only the first portion of tandem HDC-ASCR. The median number of inpatient days and days of exposure to antibiotics, opioids, and total parenteral nutrition were higher in the tandem group than in the CEM and BuMel groups. However, the rate of use of several ICU-level resources per 1000 hospital days was lower for the tandem group.</p>

<p><strong>CONCLUSIONS: </strong>These data suggest that while patients undergoing tandem HDC-ASCR were hospitalized longer, the severity of illness during hospitalization was not greater in tandem patients.</p>
