Readmission Radar

Your dataset contains 623 inpatient stay records from a small hospital. Each record represents a patient discharge, and includes the patient ID, admission date, and discharge date.

Your task is to calculate the hospital's 30 day readmission rate.

Notes:

• A discharge counts as a 30-day readmission when the same patient is admitted again within 30 days of their discharge date

• Day 30 is included in the readmission window

• Assume that all records in the dataset have had a full 30-day follow-up window
