“…Results show that patient choice is positively influenced by a hospital's decision to "focus" or specialize (e.g., cardiology) and to invest in a "related focus" in areas of expertise associated with this specialization (e.g., endocrinology, respiratory, and digestive systems), finding that patients see these choices as signals of the hospital's expertise. Sunder and Thirumalai's (2024) findings trigger a follow-up question regarding whether a patient's health is better served by a provider's specialization versus diversification strategy. We suspect that while consumer choice benefits from having a broad (but shallow) array of health services available in a nearby hospital, consumer health is likely better served by deep knowledge that matches a consumer's disease state.…”
