Estimate cost of providing methadone maintenance treatment at a methadone clinic in Nairobi Kenya: direct costs.

Methadone maintenance treatment is reported as cost-effective in treatment of opioid use disorder. Estimated cost of providing methadone varies widely in different regions but there is no data regarding cost of methadone treatment in Kenya. The aim of this study was to estimate the cost of methadone maintenance treatment at a methadone maintenance treatment clinic in Nairobi, Kenya from the perspective of the government, implementing partner and the clients. Data was collected for the period of February 2017 to September 2018 for 700 enrolled clients. The cost of providing methadone treatment was estimated as the sum of salaries, laboratory test, methadone and other commodities costs. The outcome was daily cost of methadone per client. The costs are given in Kenya Shillings (Ksh). The cost of treating one client is approximately Ksh. 149 (US$1.49) per day which amounts to Ksh 4500 (US$ 45) per month. This is from the estimated direct costs such as salaries which accounted for 86.4%, methadone 9.6%, tests and other consumables at 4%. The estimated average dose per patient per day is 60mg.This excludes indirect costs such as capital and set up cost, maintenance cost, training, drug import and distribution and other bills. The findings of this study show that the estimate cost of providing methadone at Nairobi, Kenya is comparable to that in other centers. This can help to inform policy makers on continued provision of methadone treatment in the country.
