Average hospital stay for premature babies


Some of our wonderful forum members have been hard at work finding out what is the average time a premature baby will stay in hospital for depending on their gestation when born.

We had over 190 premature births recorded from 23 week gestation up to 36 weeks to help figure out the average length of stay. The stats are very interesting and we hope will provide another insight for parents with premature babies currently in hospital. These stats are not reflected by the weight of each premature baby, just the length of time that they spent in hospital. The averages would of course change for twins & triplets.

They are below;

  • Born at 23 weeks gestation – Average of 163 days (23+3 weeks) in hospital
  • Born at 24 weeks gestation – Average of 147 days (21 weeks) in hospital
  • Born at 25 weeks gestation – Average of 104 days (14+6 weeks) in hospital
  • Born at 26 weeks gestation – Average of 114 days (16+2weeks) in hospital
  • Born at 27 weeks gestation – Average of 89 days (12+5 weeks) in hospital
  • Born at 28 weeks gestation – Average of 74 days (10+4 weeks) in hospital
  • Born at 29 weeks gestation – Average of 60 days (8+4 weeks) in hospital
  • Born at 30 weeks gestation – Average of 51 days (7+2 weeks) in hospital
  • Born at 31 weeks gestation – Average of 39 days (5+4 weeks) in hospital
  • Born at 32 weeks gestation – Average of 36 days (5+1 weeks) in hospital
  • Born at 33 weeks gestation – Average of 21 days (3 weeks) in hospital
  • Born at 34 weeks gestation – Average of 18 days (2+4 weeks) in hospital
  • Born at 35 weeks gestation – Average of 14 days (2 weeks) in hospital
  • Born at 36 weeks gestation – Average of 11 days (1+4 weeks) in hospital

Remember that this is just an average from 190 premature births recorded and not an Australian average. Not all babies will fit within the above results. Each of the babies included in these results all had different complications at birth including IUGR (growth restriction) so they were born smaller than the average for their gestational age, dependant on oxygen for longer due to lung complications so their time in hospital greatly differed. Many babies come home on their due date however others sometimes stay a little longer depending on each child’s growth, stabilisation & feeding.
