Andersen healthcare utilization model

The Andersen healthcare utilization model is a conceptual model aimed at demonstrating the factors that lead to the use of health services. According to the model, the usage of health services is determined by three dynamics: predisposing factors, enabling factors, and need. Predisposing factors can be characteristics such as race, age, and health beliefs. For instance, an individual who believes health services are an effective treatment for an ailment is more likely to seek care. Examples of enabling factors could be family support, access to health insurance, one's community, etc. Need represents both perceived and actual need for health care services. The original model was developed by Ronald M. Andersen, a health services professor at UCLA, in 1968. The original model was expanded through numerous iterations, and its most recent form models past the use of services to end at health outcomes and includes feedback loops.
