Hypothesis
How aware are doctors of the costs of medications and what factors influence their awareness?
Conclusion
Doctors often underestimate the price of expensive drugs and overestimate the price of inexpensive ones, indicating a significant lack of awareness regarding drug costs.
Supporting Evidence
- 31% of estimates were within 20% or 25% of the true cost.
- Doctors consistently overestimated the cost of inexpensive products.
- High-cost drugs were estimated more accurately than inexpensive ones.
Takeaway
Doctors don't know how much medicines cost, which can lead to them choosing more expensive options when cheaper ones are available.

Potential Biases
Common biases included convenience sampling and unclear survey distribution methods.
Limitations
Many studies had methodological weaknesses, including low response rates and unclear sampling methods.
