|Abstract: ||Objective To compare oxygen supply options for health facilities in the Gambia and develop a decision-making algorithm for choosing
oxygen delivery systems in Africa and the rest of the developing world.
Methods Oxygen cylinders and concentrators were compared in terms of functionality and cost. Interviews with key informants using
locally developed and adapted WHO instruments, operational assessments, cost-modelling and cost measurements were undertaken
to determine whether oxygen cylinders or concentrators were the better choice. An algorithm and a software tool to guide the choice
of oxygen delivery system were constructed.
Findings In the Gambia, oxygen concentrators have significant advantages compared to cylinders where power is reliable; in other
settings, cylinders are preferable as long as transporting them is feasible. Cylinder costs are greatly influenced by leakage, which is
common, whereas concentrator costs are affected by the cost of power far more than by capital costs. Only two of 12 facilities in the
Gambia were found suitable for concentrators; at the remaining 10 facilities, cylinders were the better option.
Conclusion Neither concentrators nor cylinders are well suited to every situation, but a simple options assessment can determine
which is better in each setting. Nationally this would result in improved supply and lower costs by comparison with conventional
cylinders alone, although ensuring a reliable supply would remain a challenge. The decision algorithm and software tool designed for
the Gambia could be applied in other developing countries.|
