Pediatric Short Bowel Syndrome: Real-World Evidence on Incidence and Hospital Resource Use From a Finnish Data Lake.

Objectives: Little is known about the epidemiology and healthcare burden of pediatric intestinal failure (IF). We aimed to assess the incidence, prevalence, healthcare resource utilization (HCRU), and related costs of pediatric short bowel syndrome (SBS) using follow-up data from the largest hospital district in Finland.

Methods: This retrospective registry study utilized electronic healthcare data covering all pediatric patients with SBS-IF born between 2010 and 2019 at the Hospital District of Helsinki and Uusimaa in Finland. Patients were followed from birth until the end of 2020 and compared to control patients, all from the same hospital system.

Results: In total, 38 patients with SBS-IF and 1:5 matched controls were included, with median follow-up time of almost 6 years from birth. Over half of the patients were born early preterm (gestational age ≤30 weeks). The incidence of pediatric SBS-IF was 24 per 100,000 live births. The HCRU was higher compared to controls and most of the inpatient days incurred during the first year of the SBS-IF patients' life. The average hospital-based HCRU costs were €221,000 for the first year and €57,000 for whole follow-up annually. The costs were higher for the early preterm patients and accumulated mainly from inpatient days.

Conclusions: SBS-IF is a rare disease with a relatively low number of patients treated at each hospital district. The burden on the hospital system, as well as the patient's family, is especially high at the onset as the newborns with SBS-IF spend a significant part of their first year of life in the hospital.
