The number of clinical records selected for review is typically based on which factor?

The average daily census of the organization is the most relevant factor when determining the number of clinical records selected for review. This figure provides a more accurate representation of patient volume during a specific timeframe, reflecting the facility's operational activity. By considering the average daily census, auditors can ensure that the sample size is proportional to the number of patients actually being treated, leading to a more meaningful and representative review of clinical practices. This approach helps maintain consistency in quality assessments and applies adequate scrutiny to the records of patients that actively utilize the facility’s services, thus supporting the goal of improving care quality and compliance with regulatory standards.

The other options do not provide a suitable basis for selecting clinical records for review. The total number of patients, while important, does not account for fluctuations in patient volume, as it may include patients who are no longer active. The hospital's revenue is not directly linked to patient care quality or record review and may vary due to many factors unrelated to clinical practices. Lastly, the number of staff members available does not correlate with the volume of patient care and could lead to skewed results if considered a metric for record selection.
