Abstract. A key bench mark of successful therapeutic policy implementation, and thus effectiveness, is that the recommended drugs are available at the point of care. Two years after artemether-lumefathrine (AL) was introduced for the management of uncomplicated malaria in Kenya, we carried out a cross-sectional survey to investigate AL availability in government facilities in seven malaria-endemic districts. One of four of the surveyed facilities had none of the four AL weight-specific treatment packs in stock; three of four facilities were out of stock of at least one weight-specific AL pack, leading health workers to prescribe a range of inappropriate alternatives. The shortage was in large part caused by a delayed procurement process. National ministries of health and the international community must address the current shortcomings facing antimalarial drug supply to the public sector.The widespread failure of chloroquine and sulfadoxine pyrimethamine (SP) in the treatment of malaria in Africa during the late 1990s resulted in a turbulent public health debate, which led to universal acceptance that mono-therapies that failed to cure up to one in four patients should be replaced by highly efficacious artemisinin-based combination therapy (ACT). 1-3 More than 40 countries in Africa have now adopted ACT as their first line treatment recommendation for uncomplicated malaria. 4 Beyond the difficulties of changing national treatment policies, a key bench mark of successful policy implementation, and thus effectiveness, is that the recommended drugs are available at the point of care. [5][6][7] In most countries, ACTs are supplied only to the public, formal health sector managed by the government and its mission sector partners. In 2006, Kenya implemented a change in malaria treatment policy in all public facilities from SP to the ACT artemetherlumefantrine (AL), largely supported by the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM). 7 Two years after AL introduction, we carried out a crosssectional survey to investigate AL availability in government facilities. From August 18 through October 2, 2008, 164 facilities (115 dispensaries, 30 health centers, and 19 hospitals) were assessed in seven districts in Nyanza, Western, and Coast Provinces, Kenya, that were highly endemic for malaria. At each facility, information was collected on the availability of AL packs for the four patient weight groups either through direct review of stock cards or through phone interviews. Health workers were also asked what they prescribed in the absence of AL.One (25.6%) of four of the surveyed facilities had none of the four AL weight-specific treatment packs in stock, with such complete stockouts more common in dispensaries (30.4%) than in health centers (20.0%) and hospitals (5.3%). Furthermore, three (75.0%) of four facilities were out of stock of at least one weight-specific AL pack (Table 1 ). It was particularly worrying that packs for the youngest age group, the group most at risk of malaria mortality, were absent...
