Prior to December 2016, the state had various vertical supply chain systems that resulted in wastage, duplication of efforts and overburdened the system with parallel structures. MNCH2 introduced the concept of Sustainable Drugs Supply System (SDSS) that harmonised and integrated all vertical supplies chains. The SDSS includes both free programmes (Free Maternal Newborn and Child Health, National Malaria Control Elimination Programme, TB/Leprosy, immunisation, HIV/AIDs) and not-for-free programmes (Drugs Revolving Fund, National Health Insurance Scheme, and the State Contributory Health Care Programme). This has resulted in all programmes having a uniform coordinating body. The programmes support each other, and this promotes sustainability.
