Practice Strategy Tip: Calculating Par Levels to Avoid Supply Shortages in Your Practice

Setting a par level minimum and maximum for each of the vaccines you administer is a smart way to ensure you never run out of needed vaccines during clinic. Follow these steps to calculate your minimum and maximum par levels and form a quick and easy strategy when ordering vaccines.

Step 1

Calculate the average number of doses you administer per vaccine per week (not including VFC vaccine). You can look at 3 months worth of billed CPT data or your clinic logs. Remember that some vaccines like Bexsero or Fluarix may be seasonal and quantities vary widely from month to month.

Step 2

Decide the minimum amount of weeks supply you need to have on hand at any one time. For example, your practice may decide to have at least 3 weeks worth of doses on hand at all times in case of delayed shipments or busier than average clinics.

Step 3

Add two weeks worth of doses to determine the maximum amount of doses of the vaccine you would like to have in your refrigerator..

Step 4

Once the par level range is determined, use these minimum and maximum amounts to trigger the decision to order when performing weekly vaccine counts.

Example: Your practice uses 20 doses of Pediarix a week. Therefore, your par level range is a minimum of 60 doses and a maximum of 100 doses. When you are performing your weekly count, you realize that you have 57 doses of Pediarix. Since this number is below your 3 week minimum par level, you decide to order 40 doses of Pediarix to bring your count to 97 doses. This is very close to your 5 week par level of 100 doses. You will not need to order again until the number of Pediarix doses drops below 60.
