Which method is least desirable for providing customer support?

The method of giving another patient's phone contact for questions is least desirable for providing customer support because it raises several significant concerns. Firstly, confidentiality and privacy are paramount in healthcare settings. Sharing another patient's contact information can violate privacy laws and ethical standards, such as HIPAA in the United States, which protects sensitive patient information.

Further, relying on another patient for support does not ensure that the information provided is accurate or reliable. Every patient's experience is unique, and they may not have the correct answers or the understanding needed to address someone's specific situation or concerns. This could lead to misinformation, further confusion, or even distress for the person seeking assistance.

In contrast, the other methods listed—such as offering an FAQ section online, providing a contact number, and offering written directions for self-help—are all structured, controlled, and designed to provide consistent and accurate information to users. They respect privacy while ensuring that patients receive the help they need in a reliable manner.
