Navigating payer heterogeneity in the United States: lessons for primary care.

With most providers accepting private and public funding, the US exemplifies hybridization, which results in both systemic benefits and harms. While this practice stimulates innovation, encourages practices to be efficient, and increases choice, it has also been linked to gaps in patient safety and overtreatment. We propose three lessons from the US for navigating a public and private system: hybridization allows for innovation; hybridization leads to administrative complexity; and if the costs of participation outweigh the benefits, practices may undergo dehybridization.
