Q36. While installing a printer in a newly remodeled office at a large physician's practice, you consider what the best placement for the printer might be in order to protect patient's health information. Which of the following is a good guideline for printer/fax/copier policy?
A. PHI should never be printed on a shared or networked printer.
B. PHI in hardcopy form should be disposed of as soon as possible.
C. Printers and copiers used for printing of PHI should be in a secure, non-public location. If the equipment is in a public location, the information being printed or copied is required to be strictly monitored.
D. Physical access to the printer should be restricted only to providers.
Explanation: Ideally, printers, faxes and copiers in a healthcare facility should only be placed in secure, non-public locations. However, there are some high traffic areas where healthcare personnel interact with the publiA, C printer may be required for receipts, patient instructions and other documentation. A printer in this location should be strictly monitored, any hardcopies should be picked up promptly and given to the correct recipient, filed or disposed of as needed. Answer: D is incorrect. Many employees require access to printers, faxes and copiers, and access cannot be limited to one type of employee. There are many employees that will need access to PHI to carry out the functions of a healthcare facility, not just for treatment, but for the business operations of the facility. Printing access must be managed wisely and monitored closely to protect PHI, but this kind of extreme restriction would not allow the facility to function properly. Answer: A is incorrect. Many facilities have multiple workstations and mobile devices connected to a shared printer. Although extra care needs to be exercised both in the network security of the printer as well as the physical security of hardcopy documents printed out, it is possible to protect PHI and still use a shared printer. Often, one individual in physical proximity to the shared printer is assigned responsibility for the security of the hardcopy printouts and that they are promptly picked up so that no PHI exposure is risked. Answer: B is incorrect. Destroying hardcopies as a means of protecting PHI may actually cause some information to be lost. It is important to always observe the policies of record retention and disposal that the healthcare organization has set up in order to make sure that key information is properly filed and eventually disposed of in an approved manner.
