In healthcare, “risk” has (at least) two meanings,
Usually refers to the amount of financial risk assumed by an organization or individual when providing healthcare. This used to be solely the responsibility of insurance carriers. With the advent of managed care in the US, providers are sharing more of that risk in the form of a PMPM rate negotiated with insurance carriers or large (self-insured) employers. (See “At Risk.”)
For an individual, risk represents such probabilities as the likelihood of surgical complications, medication side effects, exposure to infection or other factors.
