Outcome of critically ill children before and after the establishment of a pediatric retrieval service as a component of a national strategy for pediatric intensive care.
OBJECTIVE: To compare outcomes of critically ill children transferred for intensive care by specialist and nonspecialist retrieval before and after the establishment of a dedicated pediatric intensive care transfer service. DESIGN: Prospective, observational study. SETTING: All hospitals that admitted children in a defined geographic region of the United Kingdom. PATIENTS: There were a total of 284 critically ill children (<16 yrs old) transferred from a district general hospital to a tertiary pediatric intensive care unit. MEASUREMENTS AND MAIN RESULTS: Age, diagnosis, Pediatric Risk of Mortality score, Therapeutic Intervention Scoring System, details of interhospital transfer, and survival to hospital discharge were analyzed for two periods, before and after the establishment of a regional transfer service. Patients were categorized as low or high risk (predicted mortality, </=15% or >15%, respectively). Standardized mortality was calculated as the ratio of observed to predicted deaths in each category. After the transfer service was established, a significantly higher proportion of high-risk children were transferred by a specialist team, and there was a decreased standardized mortality rate of transferred patients (1.09 to 0.74). The greatest decrease in standardized mortality rate occurred in low-risk children transferred by nonspecialist teams (2.27 to 0.52). During the equivalent period in the same geographic region, standardized mortality rate of nontransferred children also fell in pediatric intensive care (1.59 to 0.60) and general intensive care units (1.11 to 0.81). CONCLUSIONS: We conclude that the establishment of a regional transfer service coincided with a fall in standardized mortality that reflected more general changes in intensive care performance rather than a specific benefit of a specialist transfer team.
