Read this: Health care delivery in Nigeria is a concurrent responsibility of the three tiers of government in the country, and the private sector. Nigeria has been reorganising its health system since the Bamako Initiative of 1987, which formally promoted community-based methods of increasing accessibility of drugs and health care services to the population, in part by implementing user fees. The new strategy dramatically increased accessibility through community-based healthcare reform, resulting in more efficient and equitable provision of services. A comprehensive approach strategy was extended to all areas of health care, with subsequent improvement in the health care indicators and improvement in health care efficiency and cost.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): When did the Bamako Initiative begin?
1987
