  "validation_description": "Hamilton et al, 2020Clinical coding of pleural empyema was validated using coding data from three hospitals in England, UK. The coded diagnoses of pleural empyema is defined as J86-, also known as pyothorax.  Empyema was considered as a pleural effusion that had a documented pH of less than 7.2, microscopic evidence of infection, or frank pus. If microscopic evidence was not available, then clear clinical management as empyema (supporting radiology, clinical progress, and biochemistry) was used.The clinical diagnosis of empyema was made on retrospective review of the notes, discharge summary, radiology, and microbiology available.Empyema was considered as a pleural effusion that had a documented pH of less than 7.2, microscopic evidence of infection, or frank pus. If microscopic evidence was not available, then clear clinical management as empyema (supporting radiology, clinical progress, and biochemistry) was used.Empyema coding was generally good (>85% accuracy), although some cases were miscoded. Using codes for elective admissions helped to differentiate post-operative from community acquired empyema. It is likely empyema is under rather than over-recorded in HES data.Using codes for elective admissions helped to differentiate post-operative from community acquired empyema.
