1. What is the 90 Day Post Op Calculator?

The 90 Day Post Op Calculator determines the end date of the critical 90-day postoperative period by adding 90 days to the surgery date. This period is commonly used in surgical outcome studies and quality metrics.

2. How Does the Calculator Work?

The calculator uses a simple date calculation:

Where:

• Surgery Date — The date when the surgical procedure was performed
• 90 days — Standard postoperative monitoring period

3. Importance of 90-Day Post-Op Period

Details: The 90-day postoperative period is critical for monitoring surgical outcomes, complications, and recovery. Many surgical quality metrics and research studies use this timeframe to evaluate results.

4. Using the Calculator

Tips: Enter the surgery date in YYYY-MM-DD format. The calculator will automatically add 90 days and display the end date of the postoperative period.

5. Frequently Asked Questions (FAQ)

Q1: Why is 90 days used as the postoperative period?

Q2: Does this include the day of surgery?
A: The calculation adds 90 calendar days starting the day after surgery (day 1 is first postoperative day).

Q3: How are leap years handled?
A: The calculator automatically accounts for leap years in the date calculation.

Q4: Can I calculate periods other than 90 days?
A: This calculator specifically calculates the standard 90-day period. For other timeframes, a different calculator would be needed.

Q5: Is this used for all surgical specialties?
A: While commonly used, some specialties may use different postoperative periods (30 days, 1 year) depending on the procedure and outcomes being measured.
