Abstract
There is growing recognition of the importance of rehabilitation through immediate and long-term follow-up, and neonatal intensive care unit (NICU) aftercare is emerging as an important field to consider rehabilitation services. An increasing number of children born are admitted to the NICU with complications commonly related to low birth weight, premature birth, and development of underlying diseases.
Introduction
High-risk newborns are infants who experience difficulties adapting after birth, have an elevated risk of mortality and morbidity, and require immediate medical attention in the neonatal intensive care unit (NICU) [1]. An increasing percentage of newborns (10%–15%) require admission to the NICU [2].
Materials and Methods
A nationwide retrospective cohort analysis was performed using claims data provided by the Korean National Health Insurance Service (NHIS) database for infants born between January 1, 2011 and December 31, 2021. The use of claims data was approved by the NHIS (NHIS-2023-1-244), and pseudonymized data were provided to prevent personal information identification.
Results
Among the 67,250 eligible patients, 39,711 (59.0%) and 27,539 (41.0%) were classified into the non-NICU and NICU groups, respectively. PSM resulted in a total of 16,262 patients per group (Table 1).
Discussion
This study, which analyzed the rehabilitation patterns of newborns admitted and not admitted to the NICU, revealed that (1) after the first rehabilitation session, patients in the non-NICU group received a higher number of interventions during the subsequent two years.
