Under the infection control program, what must a facility investigate and attempt to control?

The correct choice relates to procedures as they are a critical aspect of infection control programs within healthcare settings, including nursing homes. Investigating and controlling procedures is essential because these are the protocols and methods employed by staff that can directly impact the spread of infections.

Infection control measures often focus on procedural adherence, such as hand hygiene, use of personal protective equipment (PPE), sterilization of equipment, and safe handling of linens. Any breakdown in these procedures can lead to infections within the facility, making it paramount for the facility to continually assess and enhance these protocols to maintain a safe environment for residents and staff.

The other options, while relevant to different aspects of healthcare, do not directly pertain to the core focus of an infection control program. Medications, vaccines, and therapies are important components of patient care but may fall under broader categories of treatment and management, rather than the procedural processes that govern infection control. Hence, focusing on the procedures within the infection control program enables a nursing home to systematically address and mitigate the risks associated with infections effectively.
