Managed care today is being shaped by the emergence of a savvier, better informed health care consumer. Facing a strikingly similar consumer movement over the past two decades, the banking industry experienced a market transformation that holds important lessons for managed care. Nontraditional entrants in the financial services industry, offering focused "monoline" products and services closely analogous to "carve-out" providers in health care, targeted rising consumer demands and stronger preferences. Banks in time answered these formidable new competitive forces with innovative consolidation and globalization strategies. The most successful initiatives in healthcare, as in banking, will focus on satisfying the consumer's hunger for information, improved levels of service, and enhanced outcomes. Managed care plans may play a lead role in accelerating the impact of consumerism by bridging the disconnect between patients and their purchasing decisions.
