4 multiple choice 1 point
which of the following is a structural factor that may encourage or discourage the use of health services?
consumer attitudes
physician training levels
availability of services
median age of the population

Explanation:

For question 3: Straight - line projections assume a linear relationship based on past data. But in healthcare, many factors (e.g., new diseases, medical advancements) can change service utilization. So past utilization (the basis of straight - line projections) may not predict future utilization.
For question 4: Structural factors relate to the setup or infrastructure of the healthcare system. Availability of services is a structural aspect (e.g., number of hospitals, clinics), while consumer attitudes are behavioral, physician training levels are human - resource related (but not structural in the sense of system setup), and median age is a demographic factor.

Answer:

1. Past utilization is not necessarily a predictor of future utilization.
2. Availability of services.
