The purpose of this evaluation was to assess the functioning of the hospital set-up in Léogâne, Haiti one year after its implementation and to capture the lessons learned in order to inform other missions that attempt this type of set-up. The conclusions are based on two visits, the first at the 6-month mark and the second approximately one year following the initial implementation. In general, there is a positive attitude towards the set-up and the advantage of quick and relevant decision-making was felt in most departments at almost all levels. The level of buy-in of the set-up at the director level was high at the time of both visits, which was an important factor in the contribution to the successes. As a demonstration of this, most staff would do another mission in this type of set-up.
