Using SQL AVG to Monitor Treatment Outcomes

The AVG function in SQL calculates averages, something we often use in clinical audits.

For example, if I wanted to find the average duration of vancomycin therapy:

SELECT AVG(DurationDays) AS AvgTherapyLength
FROM MedOrders
WHERE DrugName = 'Vancomycin';

Practical idea:

• Find the average turnaround time for lab results.
• Calculate the average dose per administration for a specific drug.

AVG is another small building block for more complex analytics down the line.
