Prevalence

Population / CalculatorPrevalence Comments / Study / Link
Cirrhosis patients admitted to the hospital 27% JAMA. 2008;299(10):1166-1178. http://jama.ama-assn.org/cgi/content/full/299/10/1166
Cirrhosis patients with prior SBP 0% Much higher prevalence - these patients are placed on prophylactic antibiotics.
Cirrhosis patients with low ascitic protein 0% Much higher. These patients get prophylactic antibiotics.
