[This corrects the article DOI: 10.1186/s40545-015-0044-4.].

Following publication of the original version [1] of the article in the Journal of Pharmaceutical Policy and Practice, it was brought to our attention that the Alliance for Health Policy and Systems Research’s support is missing in the acknowledgement section.

The authors would like to add the following text:

“The authors would like to acknowledge the support of the Alliance for Health Policy and Systems Research (HSR/HIS), World Health Organization which supported the development of this case study and publication of this work.”
