“ The study, which appears today in the British Medical Journal (BMJ), looked at 980,876 procedures performed in US hospitals by 47,489 surgeons. Of those procedures, 2,064 (0.2%) took place on a surgeon’s birthday” Actual data:
2064/980876 operation on bday 6.9% die, rate = 142 death Expected: (if we use non bday death rate) 1/365=0.0027
2687 operation
With better 5.6% death rate
= 150 death So deaths are only 6% more, so basically they are doing less and more emergency operations on birthday, so death rate is increasing it seems. It means they are making 23% less operations on birthday then any normal day. |
