Conducting documentation audits can be challenging due to: 1. Volume of Records: Large volumes of patient records can make the audit process time-consuming. 2. EHR Systems: Variability in electronic health record (EHR) systems can complicate the audit process. 3. Human Factors: Errors and inconsistencies can arise from human factors such as fatigue or lack of training. 4. Resistance to Change: Staff may resist changes recommended by the audit, impacting the implementation of improvements.
