↵* The data items used in the routine inpatient data for England (Hospital Episode Statistics) were as follows for: primary reason for admission (method of admission); source of admission (source of admission); specialty of care in first 24 h (specialty responsible for the first 24 h of care); specialism of surgeon (specialty in which the consultant was working during the episode of surgery); mortality during admission, date of death, mortality after discharge (date of death and method of discharge); date of discharge (date of discharge); major comorbidities, indications for surgery, postsurgical complications (all diagnosis codes); sigmoidoscopy/colonoscopy, type of surgical intervention, surgery performed (all operation codes); date of sigmoidoscopy, date of surgery (date of operation). The OPCS-4 codes used for sigmoidoscopy/colonoscopy were H22, H25, H28 and for surgery (colectomy) were H04–H11, H33. The ICD-10 codes used for comorbidities were as follows: diabetes (E10–E14), ischaemic heart disease (I20–I25), COPD (J41–J44), renal failure (N17–N19), stroke (I61–I69), liver disease (K70–K77) and peripheral vascular disease (I70–I74).
↵† Figures for these audit data items are sometimes based on very low numbers of cases.
↵‡ The relatively low percentage match for CD—compared with that for UC— is because patients with Crohn's disease were more likely to have surgery other than colectomy (elsewhere along the gastrointestinal tract rather than on the colon) which was used as the basis for these comparisons.
CD, Crohn's disease; COPD, chronic obstructive pulmonary disease; ICD-10, International Classification of Diseases; NA, data items were not collected; UC, ulcerative colitis.
