Fig 1.
The multistate model used here to describe the neonatal care pathway.
All babies begin in the birth state before following transitions (arrows) throughout the model until reaching death or discharge.
Table 1.
Summary statistics of babies born at 24+0 to 31+6 weeks gestational age and discharged between 2011 and 2014.
Fig 2.
The percentage of babies receiving each level of care, or who have died or been discharged, over time.
Table 2.
Number of babies to enter and visit each state within the multistate model.
Fig 3.
The probability of babies, adjusted for gestational age, receiving each level of care, or who have died or been discharged, over time.
Table 3.
Probabilities of 24 week babies receiving each level of care or who have died or been discharged estimated from the multistate model with an adjustment for gestational age.
Table 4.
Probabilities of 31 week babies in each level of care or who have died or been discharged estimated from the multistate model with a categorical term for gestational age.
Note that everyone has at least one day of care.
Table 5.
Expected time spent receiving each level of care, and total length of stay, by gestational age.
Results are rounded up to the nearest day.
Table 6.
Hazard ratios of each transition by gestational age.
The hazard ratio compares back to the baseline of 27 weeks gestational age for that transition.
