Although the 10th revision of the International Classification of Diseases (ICD-10) was recently introduced in the United States in October 2015, the World Health Organization is already working on the next iteration (ICD-11) to be released in 2018. This survey study of nearly 250 stakeholders from around the world identified priorities for improvements, including the need for code clustering and improved codes for adverse events and diagnosis timing. A related study outlines the recommendations made by the ICD-11 Quality and Safety Topic Advisory Group, advancing specific frameworks to address many of these suggestions.
