Which of the following factors can prevent patients from voicing complaints?

Unawareness of complaint procedures is a significant factor that can prevent patients from voicing complaints. When patients do not know how to express their grievances, they may feel helpless or unsure about the process of lodging a complaint. This lack of awareness can stem from inadequate communication about the healthcare provider's complaint procedures, leaving patients without the necessary information to express their concerns effectively.

Informing patients about how to voice complaints can empower them and enhance their overall experience. It ensures that patients feel heard and validates their experiences. When patients are aware of the steps to take in lodging a complaint, it increases the likelihood that they will engage in that process, potentially leading to improvements in care or services based on their feedback. By addressing this factor, healthcare organizations can foster a transparent and open environment that encourages dialogue and ultimately enhances patient satisfaction and safety.

Other factors may indeed influence whether patients voice complaints, but unawareness specifically inhibits action due to a lack of knowledge on how to proceed.
