  abstract = {{B}ackground {T}he provision of emergency and hospital care has become an integral part of the global vision for universal health coverage. {T}o strengthen secondary care systems, we need to accurately understand the time necessary for populations to reach a hospital. {T}he goal of this study was to develop methods that accurately estimate referral and prehospital time for rural districts in low and middle-income countries. {W}e used these estimates to assess how local geography can limit the impact of a strengthened referral programme in a rural district of {M}adagascar. {M}ethods {W}e developed a database containing: travel speed by foot and motorised vehicles in {I}fanadiana district; a full mapping of all roads, footpaths and households; and remotely sensed data on terrain, land cover and climatic characteristics. {W}e used this information to calibrate estimates of referral and prehospital time based on the shortest route algorithms and statistical models of local travel speed. {W}e predict the impact on referral numbers of strategies aimed at reducing referral time for underserved populations via generalised linear mixed models. {R}esults {A}bout 10% of the population lived less than 2 hours from the hospital, and more than half lived over 4 hours away, with variable access depending on climatic conditions. {O}nly the four health centres located near the paved road had referral times to the hospital within 1 hour. {R}eferral time remained the main barrier limiting the number of referrals despite health system strengthening efforts. {T}he addition of two new referral centres is estimated to triple the population living within 2 hours from a centre with better emergency care capacity and nearly double the number of expected referrals. {C}onclusion {T}his study demonstrates how adapting geographic accessibility modelling methods to local scales can occur through improving the precision of travel time estimates and pairing them with data on health facility use.},
