Potential economic impact of hospital-acquired infections in uninsured patients: a preliminary investigation.
We studied uninsured patients admitted to Rhode Island Hospital from January 1 through June 30, 2005, and from January 1 through June 30, 2006. The mean total hospital charge for an uninsured patient with a hospital-acquired infection was $18,487; for those without such an infection, it was $4,951 (P < .001). Multivariable linear regression revealed that a hospital-acquired infection accounted for 11.8 excess hospital days (P = .001). Length of stay was the only independent variable associated with total excess hospital charges.
