Insights

A new Japanese version of the Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale effectively assesses iatrogenic withdrawal syndrome (IWS) in Japanese pediatric intensive care units (PICUs). This validated tool aids in early detection and management of IWS in children.

Area of Science:

  • Pediatric critical care medicine
  • Pharmacology and toxicology
  • Clinical nursing and patient monitoring

Background:

  • Iatrogenic withdrawal syndrome (IWS) is a significant clinical issue in Japanese pediatric intensive care units (PICUs).
  • A validated instrument for assessing IWS in Japanese pediatric patients was previously unavailable.
  • The Sophia Observation withdrawal Symptoms-Paediatric Delirium (SOS-PD) scale is a globally recognized tool for IWS evaluation.

Purpose of the Study:

  • To validate the Japanese version of the SOS-PD scale for use in Japanese PICUs.
  • To establish the criterion validity and inter-rater reliability of the Japanese SOS-PD scale.

Main Methods:

  • A prospective, observational cohort study was conducted in a single-center Japanese PICU.
  • Participants included neonates to 20-year-olds without pre-existing neurological conditions or coma.
  • Criterion validity was assessed by comparing Japanese SOS-PD scores between sedative/opioid tapering (WEAN) and stable medication (MAIN) groups, and correlated with NRSobs.
  • Inter-rater reliability was evaluated using kappa statistics and intraclass correlation coefficient (ICC).

Main Results:

  • The WEAN group showed significantly higher scores on NRSobs and the IWS component of the Japanese SOS-PD scale compared to the MAIN group (p < 0.001).
  • A strong positive correlation was found between the Japanese SOS-PD IWS component and NRSobs (r = 0.91, p < 0.001).
  • Excellent inter-rater reliability was demonstrated, with a kappa coefficient of 0.95 and an ICC of 0.98.

Conclusions:

  • The Japanese version of the SOS-PD scale is a valid and reliable instrument for assessing IWS in Japanese PICUs.
  • This validated scale facilitates early detection and appropriate management of pediatric IWS in Japan.
  • Implementation of the Japanese SOS-PD scale has the potential to improve patient care quality in pediatric critical care settings.
