Insights
Mortality after cardiopulmonary resuscitation (CPR) in hospitalized infants is high, especially for premature or younger infants with congenital anomalies. Identifying high-risk infants is crucial for improving survival rates.
Area of Science:
- Neonatal intensive care
- Pediatric critical care
- Cardiopulmonary resuscitation research
Background:
- Hospitalized infants undergoing cardiopulmonary resuscitation (CPR) are a vulnerable population.
- Limited recent data exist on factors influencing survival after CPR in neonates.
Purpose of the Study:
- To identify demographic characteristics, diagnoses, and cardiopulmonary support levels associated with survival to hospital discharge after CPR in infants.
- To analyze risk factors for mortality in infants requiring CPR.
Main Methods:
- A retrospective cohort study was conducted using data from 348 neonatal intensive care units.
- Infants aged 2 to 120 days receiving CPR between 1997 and 2012 were included.
- Multivariable logistic regression analyzed predictors of death after CPR, accounting for center clustering.
Main Results:
- The study included 2231 infants; 51% survived to discharge.
- Lower gestational age, postnatal age, 5-minute APGAR scores, congenital anomalies, and illness severity markers predicted higher mortality.
- Mortality rates following CPR did not significantly change over the study period.
Conclusions:
- Infant mortality after CPR remains high, particularly for premature infants, those with congenital anomalies, and those requiring prior cardiopulmonary support.
- Focusing on high-risk infant populations may reveal targets for CPR prevention strategies and outcome improvement.
- Further research is needed to refine interventions for this critical patient group.
Background:
Hospitalized infants requiring cardiopulmonary resuscitation (CPR) represent a high-risk group. Recent data on risk factors for mortality following CPR in this population are lacking.
Aims:
We hypothesized that infant demographic characteristics, diagnoses, and levels of cardiopulmonary support at the time of CPR requirement would be associated with survival to hospital discharge following CPR.
Study Design:
Retrospective cohort study.
Subjects:
All infants receiving CPR on day of life 2 to 120 admitted to 348 Pediatrix Medical Group neonatal intensive care units from 1997 to 2012.
Outcomes Measures:
We collected data on demographics, interventions, center volume, and death prior to NICU discharge. We evaluated predictors of death after CPR using multivariable logistic regression with generalized estimating equations to account for clustering of the data by center.
Results:
Our cohort consisted of 2231 infants receiving CPR. Of these, 1127 (51%) survived to hospital discharge. Lower gestational age, postnatal age, 5-min APGAR, congenital anomaly, and markers of severity of illness were associated with higher mortality. Mortality after CPR did not change significantly over time (Cochran-Armitage test for trend p=0.35).
Conclusions:
Mortality following CPR in infants is high, particularly for less mature, younger infants with congenital anomalies and those requiring cardiopulmonary support prior to CPR. Continued focus on at risk infants may identify targets for CPR prevention and improve outcomes.
