The most important risk factors for the development of a healthcare associated infection in the older person are the presence of an invasive indwelling device and the degree of any underlying illness.

Here's why:

1. Invasive Indwelling Device: These devices, such as catheters or ventilators, bypass the body's natural defenses against pathogens (germs), providing a direct entry point for these pathogens into the body. This significantly increases the risk of infection.

2. Degree of Underlying Illness: The sicker a person is, the more likely they are to get an infection. This is because their immune system is already compromised, making it harder for the body to fight off new infections.

While the length of hospital stay, frequency of ward changes, exposure to other patients with infections, and ability to cough properly can also contribute to the risk of infection, they are not as significant as the two factors mentioned above.
