Study summary

Peri-operative mortality depends on the patient's co-morbidities. ASA Physical Status (American Society of Anesthesiology) is the most commonly scale to assess this parameter and has yet been repeatedly criticized in the past for its discriminatory power.

Few studies have shown both the ASA physical status and the more detailed and more time-consuming Charlson Comorbidity Index to be equivalent in certain patient populations.

The purpose of this observational study is to compare the predictive value of both scales with regards to all-cause in-hospital mortality and hospital length of stay.

What researchers measure

Primary outcomes

  1. Number of patients that died after surgery during their hospital stay

    Electronic patient charts are revised for the complete hospital length of stay for co-morbidities, intra-operative data and post-operative all-cause in-hospital mortality.

    Time frame: 1 year

Secondary outcomes

  1. Hospital length of stay associated with surgery

    Electronic patient charts are revised for the complete hospital length of stay for co-morbidities, intra-operative data and post-operative all-cause in-hospital mortality

    Time frame: 1 year
