Hospital standardized mortality ratios are used for hospital performance assessment. As a first step to develop a ratio variant sensitive to the outcome of patients admitted from the emergency department (ED), we identified International Classification of Diseases, 10th Revision, Canada diagnosis groups in which high-quality ED care would be expected to reduce inhospital mortality (emergency-sensitive conditions). ⋯ We identified 37 diagnosis groups representing emergency-sensitive conditions that will enable the calculation of a hospital standardized mortality ratio relevant to emergency care.
