The objective of this study was to determine whether a correlation exists between patient age and hospital expenditures for common complex elective surgical procedures. Hospital charges at an urban academic medical center were categorized by diagnosis related group (DRG) and separated into two cohorts based on patient age (≥65 years old and <65 years old). The costliest elective procedures were identified and the average total hospital cost per procedure was calculated for each group. A Student t-test was performed to compare the average cost per procedure in each cohort and a linear regression model was performed to assess whether a linear correlation existed between patient age and cost per case. Among the costliest elective procedures identified, major elective cardiovascular, spine, and intestinal procedures were costlier in patients ≥65 years. Major transplantation, vascular procedures, and joint replacement surgery were not costlier. Further, none of the identified procedures demonstrated a linear correlation between patient age and cost per case. This finding, combined with other outcome measures, may allow us to re-examine the age limits for these complex procedures.
