According to David Pate, which of the following is NOT true regarding the differences between current efforts to focus on population health and HMOs of the 1980 and 1990s? Group of answer choices In the 1980s and 1990s, HMO stood for "health management organization," but under current efforts the phrase should be "health maintenance organization." For the most part, HMOs of the 1980s and 1990s were driven by insurance companies; current efforts like ACOs and PCHMs are provider-led. HMOs of the 1980s and 1990s focused just on the costs of care, whereas population health management efforts and future efforts should focus more on truly embracing better health, better care, and lower costs. HMOs of the 1980s and 1990s focused more on the insurer attempted to control services through denials; what Dr. Pate advocates for would allow provider organizations to handle utilization internally
