We explored intensive care units' mean ventilator-days per patient as a possible objective alternative to ventilator-associated pneumonia rates for assessing quality of care for ventilated patients. Mean ventilator-days per patient varied 4-fold within a network of community hospitals despite adjusting for multiple patient and hospital factors. Further assessment of this metric is warranted.
