Expected duration of hospital stay of low birth weight infants: Graphic depiction in relation to birth weight and gestational age

https://doi.org/10.1016/S0022-3476(05)81708-1Get rights and content

Neonatal duration of hospital stay correlated with both birth weight and gestational age in positively skewed, nonlinear relationships. Within increments of birth weight, gestational age had a semiindependent influence on length of stay. Log length of stay correlated with both birth weight and gestational age in linear, normally distributed relationships. A nomogram is provided for predicting individual lengths of stay.

    This approach allowed the estimation of parameters incorporating the correlated clusters of multiple births in a family and thus enhanced the accuracy of the predictive model. In previous reports, predictors of length of hospital stay included gestational age, birth weight, and respiratory maturity, and perinatal factors.25–27 As for predictors of ventilator days, a previous report found lower gestational age, higher admission illness severity, lower 5-minute Apgar score, presence of anomalies, male, and white race.29,30,40
