Multivariable effects of ≥1 patient safety indicator events on in-hospital mortality, prolonged length of stay and excessive hospital charges in patients undergoing major cancer surgery in the USA between 1999 and 2009

≥1 Patient safety indicator vs no PSI
VariablesOR (95% CI)*p Value
In-hospital mortality (n=51 312)†19.380 (18.439 to 20.368)<0.001
Prolonged length of stay (n=888 220)4.426 (4.313 to 4.542)<0.001
Excessive hospital charges (n=609 128)5.207 (5.097 to 5.319)<0.001
  • *Each of these effects was derived from individual multivariable logistic regression models adjusted for hospital clustering, procedure type, age, gender, race, Charlson comorbidity index, insurance status, socioeconomic status, year of admission, hospital location, hospital region, hospital volume quartiles and institutional academic status.
