I'm not in the health care industry, but I found your question interesting. I google searched & looked at some hospital websites but couldn't find much. I did find some figures & length of stay cost for various hospital admissions (not exactly what you ask for). I'll keep checking to see if anyone comes up with something else.
http://www.ahcpr.gov/news/press/pr2002/rishospr.htm Blood poisoning (septicemia)—from $17,909 to $24,365. The average hospital stay declined from 10.0 days to 8.2 days.
Heart rhythm disturbances (cardiac dysrhythmias)—from $10,152 to $14,213. Average hospital stays declined from 4.7 days to 3.6 days.
Stroke (acute cerebral vascular disease)—from $15,365 to $19,956. Average hospital stays fell from 9.5 days to 6.7 days.
Diabetes—from $11,021 to $14,779. Average hospital stays declined from 7.4 days to 5.6 days.
Pneumonia—from $12,860 to $15,104. Average hospital stays decreased from 7.8 days to 6 days.
Congestive heart failure—from $11,995 to $15,293. Average hospital stays declined from 7.4 days to 5.6 days.
Nonspecific chest pain—from $5,135 to $7,543. Average hospital stays fell from 2.5 days to 1.8 days.
Chronic obstructive lung diseases—from $11,263 to $12,491. Average hospital stays declined from 7.2 days to 5.3 days.
So on a conservative average, a bit over $2000 a day. Thank's.
