“Supplier-induced demand” refers to a situation in healthcare where healthcare providers, such as physicians or healthcare facilities, may influence or create demand for medical services beyond what would be demanded based solely on patients’ needs.

In other words, it suggests that the supply side of healthcare can have a substantial impact on the demand for medical services.

Key points regarding supplier-induced demand in healthcare include:

Physician Influence: Healthcare providers, particularly physicians, may have the ability to influence patients’ decisions regarding medical treatments. This influence can stem from factors such as financial incentives, professional reputation, or a belief in the benefits of certain procedures.
Financial Incentives: In fee-for-service payment systems, where healthcare providers are paid based on the number of services they deliver, there may be an incentive to recommend and provide more services than strictly necessary. This can contribute to an increase in healthcare utilization.
Information Asymmetry: Patients often rely on the expertise of healthcare providers to make informed decisions about their care. In situations of information asymmetry, where patients may not have complete knowledge about their condition or treatment options, healthcare providers can play a significant role in shaping treatment choices.
Medical Technology and Innovation: The introduction of new medical technologies and treatment options can contribute to supplier-induced demand. Providers may be more inclined to recommend the use of new and potentially lucrative technologies, even if existing, less costly options are effective.
Defensive Medicine: Fear of malpractice lawsuits may lead healthcare providers to practice defensive medicine by ordering additional tests or procedures to protect themselves from potential legal consequences. This defensive approach can contribute to increased healthcare spending.

Addressing supplier-induced demand often involves healthcare policy and payment system reforms aimed at aligning incentives with patient outcomes and cost-effectiveness. Transitioning to value-based care models, where reimbursement is tied to the quality and efficiency of care rather than the quantity of services provided, is one approach to mitigate the impact of supplier-induced demand in healthcare.
