Atlas Data – Hospital Discharges and Post-Acute Care – Selected Surgical Discharge Rates

Most patients defer to their physicians when it comes to deciding what care they receive. When it comes to elective surgery, physician opinion can vary widely as to when the treatment is necessary, and which patients are appropriate. Consequently, the frequency of discretionary surgery such as knee or hip replacement or back surgery, also varies remarkably from one region to another.
