I agree with the principle "money follows patient" as a first step to align demand with need. Public sector supply systems may not be able to keep up with the increased demand, therefore facilities will soon start buying from private providers, using the cash from the voucher income. Given the erratic pricing and quality problems in many countries, it would help if there is a central agency that negotiates prices for quality medicines, so that facilities can buy from one or more defined suppliers based on agreed price lists. In developed countries, this is called "pharmacy benefit management". I would like to introduce this term into our health systems glossary of terms and look at it as a distinct element at the interface of financing, payment system and service provision that is critical for ensuring access to quality medicines and cost-efficient use of resources.
