Purpose: To provide an overview of various sepsis International Classification of Diseases (ICD) coding methods and their diagnostic accuracy. Methods: We undertook a systematic scoping review between 1991 and 2020 (search terms: sepsis, coding, and epidemiology) to include studies reporting the accuracy of a sepsis ICD coding method. Studies were grouped by ICD coding method, number of diagnostic accuracy parameters, ICD version, reference standard, design, country, setting, type of dataset and sepsis definition. ICD coding methods were categorised as explicit or implicit, with the explicit methods further divided into wide and narrow groups. Descriptive statistics were used to present data. Results: We analysed 17 studies, of which 16 (94.1%) used retrospective medical chart review as the reference standard for clinical sepsis, and eight (47.1%) used hospital administrative data to identify sepsis. There were 53 assessments of various ICD coding methods, with 32 (60.4%) of them being explicit and 21 (39.6%) implicit methods. The coding methods had a median sensitivity of <75% but a median specificity of >85%. However, a wide variation was noted in the diagnostic accuracy parameters of all ICD coding methods. Most of the studies showed high methodological quality. Conclusion: None of the current ICD coding methods is optimal for identifying sepsis. [ABSTRACT FROM AUTHOR] |
