One strategy for reducing the number of preventable medical errors is the use of technology. Internal auditors understand that an automated preventive control is superior to a manual preventive control. However, despite the overwhelming evidence that bar code-enabled point-of-care (BPOC) technology improves the quality and safety of patient care, hospitals have been slow to adopt it. By incorporating internal audit into the core implementation team, organizations can increase the effectiveness of the application's controls design. The reward will be a higher return on investment for this effective technology as well as enhanced quality of care and patient satisfaction.
