The objectives of this study were to evaluate the resources and capacity of emergency trauma care services in three Peruvian cities using the WHO report Guidelines for Essential Trauma Care. This was a cross-sectional study in eight public and private healthcare facilities in Lima, Ayacucho, and Pucallpa. Semi-structured questionnaires were applied to the heads of emergency departments with managerial responsibility for resources and capabilities. Considering the profiles and volume of care in each emergency service, most respondents in all three cities classified their currently available resources as inadequate. Comparison of the health facilities showed a shortage in public services and in the provinces (Ayacucho and Pucallpa). There was a widespread perception that both human and physical resources were insufficient, especially in public healthcare facilities and in the provinces.
