1. What is Proportion Of Days Covered (PDC)?

Proportion Of Days Covered (PDC) is a medication adherence metric that calculates the percentage of days a patient has medication available over a specific measurement period. It is commonly used in health insurance to assess medication compliance.

2. How Does the Calculator Work?

The calculator uses the PDC formula:

\[ PDC = \frac{\text{covered days}}{\text{total days}} \times 100 \]

Where:

Covered Days — Number of days medication was available
Total Days — Total number of days in the measurement period

Explanation: The formula calculates the percentage of days covered by medication supply during a specific time period, providing a measure of medication adherence.

3. Importance of PDC Calculation

Details: PDC is a critical metric for health insurers and healthcare providers to measure medication adherence, which is associated with better health outcomes and reduced healthcare costs. High PDC scores indicate good medication compliance.

4. Using the Calculator

Tips: Enter the number of covered days (days medication was available) and total days in the measurement period. Both values must be positive integers, and covered days cannot exceed total days.

5. Frequently Asked Questions (FAQ)

Q1: What is considered a good PDC score?
A: Typically, a PDC of 80% or higher is considered good medication adherence for most chronic medications.

Q2: How is PDC different from MPR?
A: While both measure medication adherence, PDC is generally considered more accurate as it accounts for overlapping medication supplies and provides a more conservative estimate.

Q3: What time period should be used for PDC calculation?
A: PDC is typically calculated over a 12-month measurement period, but it can be calculated for any specific time frame depending on the assessment needs.

Q4: How are covered days determined?
A: Covered days are calculated based on prescription fill dates and days supply. Overlapping supplies from multiple fills are accounted for to avoid double-counting.

Q5: Why is PDC important for health insurance?
A: Health insurers use PDC to measure quality of care, assess provider performance, and identify members who may need additional support with medication adherence.
