The review of 100 patient records and claim forms out of 2000 indicates what type of audit?

A review of 100 patient records and claim forms out of a total of 2000 is indicative of a sampling audit. This type of audit involves examining a subset of records rather than evaluating every single record in a population. The purpose of a sampling audit is to obtain insights about the overall compliance or accuracy of the records without the need for a full evaluation, which can be resource-intensive and time-consuming.

In conducting a sampling audit, the selected records are typically chosen using specific statistical methods to ensure that the sample is representative of the larger group, allowing auditors to make valid inferences based on the limited data. This approach enables the audit team to assess trends, identify areas of improvement, and ensure adherence to regulatory standards efficiently.

Other audit types listed may involve different methodologies or scopes. A comprehensive audit would review all records in that specific category, while an external audit typically involves an independent third party reviewing the records. A concurrent audit happens in real time as services are being provided, rather than after the fact. Thus, the nature of the review distinguishing it as a sampling audit lies in the selective assessment of a portion of the records rather than a complete examination.
