5. PERFORMING A MANUAL AUDIT
c. Chart Selection
A systematic random sampling technique will provide the
best representative sample for audit. This is done in the following fashion:
Suppose you need to select 69 charts from a registry list of 1000 patients.
First, divide 1000 by 69, which yields the number 14.4. You now know that you
must select one chart out of fourteen.
Please note that it is important to track down the charts which are missing from Medical Records as these are likely to belong to patients who have been seen recently and have high compliance with the Standards of Care.
