DS17 Postoperative wound complications following dermatological surgery: an audit leading to improved clinical practice, patient outcomes and informed consent

Abstract

Abstract In 2021, an apparent spike in wound complications presenting to our dressings clinic prompted a prospective audit of complications following dermatological surgery. The aim was to quantify the rate of and identify risk factors leading to postdermatological surgery complications for clinical governance and to improve clinical practice and patient outcomes. Secondary outcomes were to provide operators with individual annual complication rates. A further outcome pertinent to the Montgomery ruling was to use the data to refine preoperative patient information with precise detail on risk prior to surgery. Patients undergoing a dermatological surgery procedure between 1 April 2021 and 31 December 2022 across three hospital sites were included in this audit. Prospective data were collected via a departmental surgical complications proforma, supplemented by collating retrospective data from nurse-led wound review clinics via our electronic patient record system. Data were gathered on patient age and sex; operator grade; presenting problem (pain/dehiscence/infection/bleeding/other); surgical site; route of referral; microbacterial swab, cultured organism, antibiotic prescribing; anticoagulation; type of procedure; suture type; days to suture removal; and provision of pre- and postoperative patient information on skin surgery. Over a 21-month period > 11 000 procedures were performed, with a median of 574 procedures per month. In total, 256 patients reported 331 complications: 124 were suspected infections (37.5%); 63 were reports of pain (19.0%), 62 of bleeding (18.7%) and 52 of dehiscence (15.7%); and 30 (9.1%) were other complications such as graft failure. Surprisingly, the majority of complications (41%) occurred on the head and neck. Of patients presenting with bleeding, most were not taking prescribed anticoagulants. Seventy-two per cent of positive swabs grew Staphylococcus aureus. In 2019, the British Association of Dermatologists (BAD) performed a national audit of process, based on measures of quality in a dermatology skin surgery service. Sixty-four per cent of 201 respondents from the BAD and British Association of Dermatological Surgery reported no formal mechanism for determining wound complications following skin surgery (https://cdn.bad.org.uk/uploads/2022/02/29200022/Skin-Surgery-National-Audit-Report-2019.pdf). In our experience, using a departmental proforma has enabled quantification of departmental postoperative complication rates against anatomical site, procedure, patient factors and level of operator, improving clinical practice, governance, informed consent and patient outcomes. It is hoped that our work might usefully contribute to the development of a national proforma for collating data on wound complications, which has wider implications for maintaining high standards of dermatological surgery practice across the UK.
