With an estimated 6000+ stores, DLDB constituted the largest licensed retail outlets for purchasing medicines in Tanzania.
However, DLDB are plagued with several problems such as a limited list of medicines that can be legally sold, not including basic essential prescription medicines, lack of adequate facilities for storing medicines properly, lack of basic qualifications and training for dispensing staff, lack of business skills for shop owners, and inadequate or non-existent regulation and supervision by inspectors.
A systematic and holistic approach to the problems of DLDBs was used to develop the Accredited Drug Dispensing Outlets (ADDO) program during the pilot program under the Strategies for Enhancing Access to Medicines (SEAM) Program funded by the Bill & Melinda Gates Foundation in 2000. The goal of the ADDO program was to increase access to essential medicines through utilization of the private sector.
All aspects of the DLDB enterprise—including the physical premises, stock maintained by the owner, consumer choices, interactions with dispensers, and recommended treatments—had to be improved. In addition, the larger systems in which DLDBs are embedded, which include licensing, supply, training, and inspection, involving ward, district, regional, and national authorities, also had to be changed and strengthened.
After gaining support from key stakeholders, TFDA and the government of the region of Ruvuma, in collaboration with MSH, implemented the pilot ADDO initiative in 2003. Quality of both products and services was ensured through a combination of government accreditation and regulation mediated through routine monitoring by district/local government and community structures.
Accreditation as applied to the ADDO program aims to improve the availability of essential medicines and the quality of services by working with independent shop owners and dispensing staff via provision of education, training and supervision; commercial incentives combined with decentralized regulatory oversight. Accreditation is granted on achievement and maintenance of a set of pre-established standards.
