The most effective method is physical destruction. Running a low-level data wipe utility may leave some residual data that could be recovered; erasing data directories and formatting hard drives are easily reversed, exposing all data on the drive to unauthorized individuals.

Sensitive functions are best described as those that can be performed manually at a tolerable cost for an extended period of time. Critical functions are those that cannot be performed unless they are replaced by identical capabilities and cannot bereplaced by manual methods. Vital functions refer to those that can be performed manually but only for a brief period of time; this is associated with lower costs of disruption than critical functions. Noncritical functions may be interrupted for anextended period of time at little or no cost to the company, and require little time or cost to restore.

The most significant risk associated with a new health records system that replaces a legacy system is data not being converted correctly, resulting in inaccurate patient records. Data conversion is the process of transferring data from one format or system to another. Data conversion is a critical step in implementing a new health records system, as it ensures that the patient data are consistent, complete, accurate, and accessible in the new system. Data not being converted correctly may cause errors, discrepancies, or losses in patient records, which may have serious implications for patient safety, quality of care, legal compliance, and privacy protection.
Staff not being involved in the procurement process, creating user resistance to the new system; the deployment project experiencing significant overruns, exceeding budget projections; and the new system having capacity issues, leading to slow response times for users are also risks associated with a new health records system implementation, but they are not as significant as data not being converted correctly.
