Should You Stay Away From Hospitals on the Weekend?
Kevin Drum points us to a post by Austin Carroll that examines a study of infants who are admitted to the hospital because they aren’t gaining enough weight. The study looks at how long each infant stays at the hospital and how much the stay costs based on what day of the week the child is admitted. Here are the results:
Drum takes this to be yet more evidence that not much gets done at hospitals on the weekend and it’s better to wait until a weekday to go. Obviously, the graph pretty clearly shows that hospital stays both last longer and cost more when the admission happens on a Saturday or Sunday. But is that really because “the babies just sit around over the weekend and then start getting treated on Monday?” Maybe, but wouldn’t you expect to see higher costs and longer visits on Friday?
After all, if a parent brings her child in on a Friday morning, receives treatment during the day and then only sporadic attention over the weekend, wouldn’t it be likelier that the visit would last longer than if the parent had brought the kid in on a Monday or Tuesday? If the parent had instead brought her child in on Sunday, received little attention during the day, but then began treatment on Monday, shouldn’t that visit be shorter than someone who brought her child in on a Friday?
In addition Carroll writes that “the number of procedures for children admitted on the weekend wasn’t any different than for children admitted on the weekdays.” Number of procedures isn’t a perfect proxy for quality of treatment, but it at least demonstrates that the infants were not just ignored the entire weekend.
Drum may be right here, but I’d like to see some more evidence for why that graph looks the way it does. No matter the reason though, I won’t argue with his conclusion: if you have the chance to choose what day of the week to enter the hospital, choose a weekday.
