Changes in intubation rates and outcome of very low birth weight infants: a population-based study
Insights
Intubation rates for very low birth weight (VLBW) infants decreased significantly in Germany. This trend improved survival without bronchopulmonary dysplasia (BPD) and did not increase adverse outcomes.
Area of Science:
- Neonatal Medicine
- Pediatric Critical Care
- Public Health
Background:
- Intubation rates for very low birth weight (VLBW) infants in Germany have shown recent indications of a decrease.
- Understanding the impact of reduced intubation on VLBW infant outcomes is crucial.
Purpose of the Study:
- To quantify the decrease in intubation rates among VLBW infants in Lower Saxony, North Germany.
- To analyze the association between reduced intubation and clinical outcomes in VLBW infants.
Main Methods:
- Analysis of population-based data from a statewide quality assurance program (2001 VLBW infants, 1992-1994).
- Inclusion criteria: infants weighing 500 to 1499 g born in Lower Saxony.
- Outcomes assessed included mortality, intraventricular hemorrhage, periventricular leucomalacia, and bronchopulmonary dysplasia (BPD).
Main Results:
- The proportion of VLBW infants not intubated and mechanically ventilated increased significantly across both weight groups (infants <1000g: 7% to 14%; infants ≥1000g: 28% to 44%).
- This reduction in intubation was not linked to increased mortality or major adverse outcomes.
- Improved outcomes observed: increased survival without BPD in infants <1000g (38% to 48%) and decreased BPD incidence in infants ≥1000g (14% to 9%).
Conclusions:
- A significant reduction in aggressive treatment (intubation) for VLBW infants was observed without adverse effects on mortality or morbidity.
- While this observational study suggests a potential benefit, it cannot definitively establish causality.
- A randomized controlled trial is necessary to confirm if selective intubation strategies improve VLBW infant outcomes.
Objective:
There have been indications of a recent decrease in intubation rates of very low birth weight (VLBW) infants in Germany. We wanted to quantify this decrease and analyze its effect on clinical outcome.
Methods:
Population-based data on the treatment and outcome at hospital discharge from a statewide quality assurance program were analyzed for 2001 VLBW infants (500 to 1499 g) born from 1992 to 1994 in Lower Saxony, North Germany.
Results:
The proportion of patients not intubated and mechanically ventilated increased from 7% to 14% in infants less than 1000 g and from 28% to 44% in those greater than or equal to 1000 g (P < .02 and < .01, respectively). This increase was not associated with any significant increase in adverse outcome such as death, intraventricular hemorrhage, periventricular leucomalacia, or bronchopulmonary dysplasia (BPD). Instead, there was an increase in the proportion of infants less than 1000 g who survived without BPD (from 38% in 1992 to 48% in 1994; P < .05) and a decrease in the proportion of infants greater than or equal to 1000 g in whom BPD developed (from 14% to 9%; P < .05).
Conclusions:
The data from a statewide quality assurance program show a significant reduction in the aggressiveness of the treatment of VLBW infants, which was not associated with an increased mortality or morbidity. This observational study, however, cannot define whether a more selective approach to the intubation of VLBW infants will ultimately result in a better outcome. A randomized, controlled trial would be required to answer this clinically important question.
