Abstract UK guidelines for the management of Stevens–Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) in adults, published by the British Association of Dermatologists (BAD) in 2016, outline a set of audit standards (Creamer D, Walsh SA, Dziewulski P et al. U.K. guidelines for the management of Stevens–Johnson syndrome/toxic epidermal necrolysis in adults 2016. Br J Dermatol 2016; 174:1194–227). Our aim was to audit the current management of SJS/TEN in adults against audit standards in the BAD guidelines. BAD members were invited to submit data on five consecutive adults with SJS/TEN per department over an 8-week period in 2022. All data were obtained from respondents using a Microsoft Excel spreadsheet proforma returned to the BAD by email. No patient-identifiable data were requested. Initial data extraction was conducted using a novel and reproducible program written in the R statistical language (V3.7 and the readxl, ggplot2 and ggthemes packages). The data analysis was also performed using Microsoft Excel. Thirty-nine (29%) dermatology centres in the UK participated and data for 147 adults with SJS/TEN were collected. Within 24 h of a diagnosis being made or suspected, the following were documented: Severity-of-Illness Score for TEN (SCORTEN) for 52% (n = 76/147) of submitted cases, list of medications for 77% (n = 113) and timelines for commencement/alterations of medications for 71% (n = 104). Initial assessment was of the eyes (by an ophthalmologist) for 48% (n = 71) of cases, the mouth in 88% (n = 130), the genital skin in 70% (n = 103) and the urinary tract in 63% (n = 93). In the first 10 days after a suspected or confirmed diagnosis of SJS/TEN, daily assessments of the mouth were documented in 18% (n = 26) of cases, the eyes in 8% (n = 12) and the urinary tract and genital skin in 10% (n = 14). Documentation regarding advice on (i) avoidance of the culprit drug was present for 58% (n = 76/130) of cases and (ii) request for a medic alert bracelet/amulet in 6% (n = 9/147). In adults with SJS/TEN, drug causality assessment was documented adequately. Initial assessment of the mouth, eyes, urinary tract and genital skin was good to fair; however, daily assessments were poor. Other audit standards that require improving include documentation of SCORTEN and advice to avoid the culprit drug and request a medic alert bracelet/amulet. In adults with SJS/TEN, there are multiple points in the assessment pathway that require careful documentation and regular review. These are a challenge for many clinical inpatient environments. Care within a burns unit or similar may not be possible for all. This audit suggests that some form of assessment and clinical review checklist might enable colleagues to maintain standards outlined in the guideline. Among these, use of SCORTEN, advice to avoid the culprit drug and requests for a Medic Alert bracelet/amulet are key.
