Perinatal regionalization system: efficiency analysis

The first principles and fundamental elements of perinatal regionalization were formulated more than 40 years ago. Over the past years this organizational model was substantially complicated and modernized. Numerous large, population-based studies describe and analyze the effects of perinatal regionalization, propose and study the possible directions of its development. It has been proven that the bed capacity of the obstetric hospital and the flow of extremely premature newborns in the hospital largely determine the outcome of the premature newborn, morbidity, mortality, long-term results, affecting important population indicators, neonatal and infant mortality. The review summarizes the data on available population studies, outlines the basic principles of the formation and development of the perinatal regionalization system.

Evaluation of Neonatal Transport in Western Switzerland: A Model of Perinatal Regionalization

Neonatal transport is an essential part of regionalization for highly specialized neonatal intensive care. This retrospective analysis of prospectively collected data on neonatal transport activity in a large Swiss perinatal network more than 1 year, aimed to quantify this activity, to identify the needs for staff, and the demands regarding know-how and equipment. Of the 565 admissions to the tertiary neonatology clinic, 176 (31.2%) were outborn patients, transported as emergencies to the level III unit. In 71.6% of cases, respiratory insufficiency was one of the reasons for transfer. Circadian and weekly distribution showed increased transport activity on workdays between 8 am and 10 pm, but regular demands for emergency transports regardless of the time frame require a neonatal transport team available 24/7. This study highlights the importance of neonatal transport and unveils several functional and infrastructural insufficiencies, which led to suggestions for improvement.

Perinatal Regionalization and Implications for Long-Term Health Outcomes in Cerebral Palsy

Background: Perinatal regionalization is linked to improved neonatal outcomes; however, the effects on long-term outcomes in cerebral palsy (CP) are not known. We estimate the effect of highest levels of neonatal care available at delivery on the risk of developing a nonambulatory CP status. Methods: Children with CP born in Quebec from the Canadian CP Registry excluding postneonatal causes were included (N=360). We estimate the effect of level of care available at delivery on risk of nonambulatory status among children with CP using propensity score matching and instrumental variables methods to adjust for differences in case mix among the three groups of hospitals. The outcome variable is an indicator for CP nonambulation assigned according to Gross Motor Function Classification System (levels IV and V). This study used data that predated therapeutic hypothermia in Quebec. Results: Propensity score estimates of change in the adjusted risk of having a nonambulatory CP status because of birth at level II versus level I is −0.081, 95% confidence interval (CI; −0.2182 to 0.0562); level III versus level I is −0.072 95% CI (−0.225 to 0.08), and level III versus level II is 0.157 95% CI (0.027 to 0.286). Conclusions: Differences in levels of neonatal care available at hospital where the delivery was carried out are not associated with the risk of a nonambulatory CP phenotype. This suggests that level of care and associated medical technology within the Quebec regionalized neonatal-perinatal system is used efficiently because it does not offer any further marginal benefit in the reduction of severe CP outcomes. The system works well as it is, which is supportive of the perinatal regionalization. The success of the neonatal resuscitation program and referral of high-risk births to regional hospitals with sufficient obstetric and perinatal competence and resources may contribute to this lack of variability.
