Exploring the impact of complications on length of stay in major surgery diagnosis-related groups.

Study Objective: To analyze, in terms of the length of stay (LOS), the use of resources by patients classified under surgical diagnosis-related groups (DRGs) with complication and/or comorbidity (DRGCCs), divided into subgroups where complications were and were not detected, and to explore the repercussions on hospital reimbursement.

Design: The Complication Screening Program(Copyright ) (CSP) was used to divide the patients in 14 DRGCCs into subgroups with and without complications, and to compare the LOS between the subgroups and with the equivalent DRG without CC. The ratios between the LOS and the relative weight of the DRGs for reimbursement were also compared.
