Summary

This observational retrospective analysis will provide useful information for clinicians and payers, and local guidelines committee members, to improve the understanding of Cytomegalovirus clinical and economic burden and clinical management of pediatric patients undergoing allogeneic Hematopoietic Stem Cells Transplantation in Italy.

Detailed description

This is an observational retrospective analysis from the main pediatric centers in Italy (approximately 5 sites). The selected sites will be the most representative of Italy because they perform about 2/3 of all allogeneic HSCT per year. Index date: date of allogeneic HSCT; retrospective data will be captured in consecutive patients undergoing allogeneic HSCT from January 2018 to June 2020 with maximum 12 months of follow-up for each patient. The data of the patients undergoing allogeneic HSCT after June 2020 will not be captured in order to avoid any possible bias due to off-label access to letermovir. Medical Records (MR) will be used to describe the risk factors, patient characteristics, treatment patterns, and healthcare resource utilization of subjects who had a CMV infection. Electronic or paper hospital charts (inpatient), clinical charts (inpatient and outpatient), and outpatient records will all be considered as MR for study purposes. This is a secondary data collection study from electronic or paper medical chart review, no data from registry will be collected. Patients (or their legally acceptable representatives) must have signed and dated the Informed Consent \& Privacy Form (ICF), if applicable.
