Readability assessment of the British Association of Dermatologists' patient information leaflets.

BACKGROUND: The British Association of Dermatologists (BAD) develops and produces patient information leaflets (PILs) for British clinicians and the general public, and its website provides access to all the PILs. Health literacy across the UK remains variable. Readability instruments assess the comprehensibility of text, predominately using a composite of sentence length and/or word-syllable number. Instruments usually report text readability categorized by United States (US) grades; ideally, health literature should be rated at US grade ≤ 6 (UK Year 7; age 11-12 years). METHODS: In collaboration with the BAD, PILs on the BAD website (n = 203) were downloaded for readability assessment. PILs were processed prior to analysis using Readability Studio software (Oleander Software, Vandalia, OH, USA). Established readability metrics were used: Flesch-Kincaid (FK), Simple Measure of Gobbledygook (SMOG), Gunning fog index (GFI), Fry, FORCAST and Flesch Reading Ease (FRE). RESULTS: The mean (95% CI) US grade levels for all BAD PILs were: 9.8 (9.7-10.0) for FK, 12.1 (12.0-12.3) for SMOG, 11.8 (11.6-11.9) for GFI, 11.5 (11.1-11.8) for Fry and 10.7 (10.6-10.8) for FORCAST. For FRE, the level is reported from a normal spectrum of 0-100, and was found to be 52.2 (95% CI 34.0-78.0) in this study. In the UK context, the mean readability levels of the BAD PILs were rated as Year 10 (age 14-15 years) for FK and Year 13 (aged 17-18 years) for SMOG. For FK, outputs, only 1.0% of PILs (2 of 203) were the recommended US grade ≤ 6 according to FK, and for SMOG rating, none was rated at this level. DISCUSSION: The majority of BAD PILs have been written at a level that will be challenging for some patients to read. Reducing sentence length and aiming for shorter words will improve accessibility.

Use of the Cutaneous Lupus Disease Area and Severity Index as an outcome measure in clinical trials: a descriptive study.

This study summarizes the use, since its inception, of the Cutaneous Lupus Disease Area and Severity Index (CLASI) as an outcome measure in clinical studies. We systematically searched the MEDLINE, PubMed, EMBASE and Cochrane databases for papers including the term 'cutaneous lupus disease area and severity index' and its abbreviations up to August 2017, identifying 205 abstracts. Following shortlisting, two independent physicians critically reviewed 71 papers for data extraction. We found that a limited number of high-quality studies used the CLASI scoring as an outcome measure. We concluded that further validation is necessary to identify the effectiveness of the CLASI in the assessment of cutaneous lupus erythematosus subtypes. The use of standardized core patient- and physician-reported outcome measures may reduce heterogeneity and allow comparisons between patients enrolled in clinical trials. This would improve the relevance within clinical practice, where the use of CLASI is currently limited.

British Association of Dermatologists National Clinical Audit on the Management of Hidradenitis Suppurativa in the UK.

BACKGROUND: The first UK guidelines for the management of hidradenitis suppurativa (HS) were published by the British Association of Dermatologists (BAD) in 2018. The guidelines contained a set of audit criteria. AIM: To evaluate current HS management against the audit standards in the BAD guidelines. METHODS: BAD members were invited to complete audit questionnaires between January and May 2020 for five consecutive patients with HS per department. RESULTS: In total, 88 centres participated, providing data for 406 patients. Disease staging using the Hurley system and disease severity using a validated tool during follow-ups was documented in 75% and 56% of cases, respectively, while quality of life and pain were documented in 49% and 50% of cases, respectively. Screening for cardiovascular disease risk factors was as follows: smoking 75%, body mass index 27% and others such as lipids and diabetes 57%. Screening for depression and anxiety was performed in 40% and 25% of cases, respectively. Support for smokers or obese patients was documented in 35% and 23% of cases. In total, 182 patients were on adalimumab, of whom 68% had documentation of baseline disease severity, and 76% were reported as having inadequate response or contraindications to systemic treatments; 44% of patients continued on adalimumab despite having < 25% improvement in lesion count. CONCLUSION: UK dermatologists performed well against several audit standards, including documenting disease staging at baseline and smoking status. However, improvements are needed, particularly with regard to screening and management of comorbidities that could reduce the long-term complications associated with HS. A re-audit is required to evaluate changes in practice in the future.

Comparing the efficacy and tolerability of biologic therapies in psoriasis: an updated network meta-analysis.

BACKGROUND: The rapid expansion of psoriasis biologics has led to an urgent need to understand their relative efficacy and tolerability to inform treatment decisions better and, specifically, to inform guideline development. OBJECTIVES: To update a 2017 meta-analysis on the comparative efficacy and tolerability of biologic treatments for psoriasis. METHODS: We searched the MEDLINE, PubMed, Embase and Cochrane databases for randomized controlled trials (RCTs), published up to 7 September 2018, of 11 licensed, NICE-approved biologics targeting tumour necrosis factor (adalimumab, etanercept, infliximab, certolizumab pegol), interleukin (IL)-12/IL-23p40 (ustekinumab), IL-17A (secukinumab, ixekizumab), IL-17RA (brodalumab) and IL-23p19 (guselkumab, tildrakizumab, risankizumab). A frequentist network meta-analysis ascertained direct or indirect evidence comparing biologics with one another, methotrexate or placebo. This was combined with hierarchical cluster analyses to consider efficacy (≥ 90% improvement in Psoriasis Area and Severity Index (PASI 90) or Physician's Global Assessment 0 or 1; PASI 75; Dermatology Life Quality Index improvement) and tolerability (drug withdrawal due to adverse events) outcomes at 10-16 weeks, followed by assessments of study quality, heterogeneity and inconsistency. RESULTS: We identified 62 RCTs presenting data on direct comparisons (31 899 participants). All biologics were efficacious compared with placebo or methotrexate at 10-16 weeks. Hierarchical cluster analyses revealed that adalimumab, brodalumab, certolizumab pegol, guselkumab, risankizumab, secukinumab, tildrakizumab and ustekinumab were comparable with respect to high short-term efficacy and tolerability. Infliximab and ixekizumab clustered together, with high short-term efficacy but relatively lower tolerability than the other agents, although the number of drug withdrawal events across the network was low, so these findings should be treated with caution. CONCLUSIONS: Using our methodology we found that most biologics cluster together with respect to short-term efficacy and tolerability, and we did not identify any single agent as 'best'. These data need to be interpreted in the context of longer-term efficacy, effectiveness data, safety, posology and drug acquisition costs when making treatment decisions.

The landscape of psoriasis provision in the UK.

Psoriasis remains one of the commonest conditions seen in dermatological practice, and its treatment is one of the greatest cost burdens for the UK National Health Service. Treatment of psoriasis is complex, with numerous overlapping lines and therapies used in combination. This complexity reflects the underlying pathophysiology of the disease as well as the heterogeneous population that it affects. National Institute for Health and Care Excellence (NICE) guidance for the treatment of psoriasis has been available since 2013, and has been the subject of three national audits conducted by the British Association of Dermatologists. This report synthesizes the results of the most recent of those exercises and places it in the context of the NICE guidance and previous audits. It clearly shows the significant burden of disease, issues with provision of services and long waiting times and the marked shift in therapies towards targeted biologic therapies.

National audit on the management of bullous pemphigoid.

BACKGROUND: Bullous pemphigoid (BP) is an autoimmune, subepidermal, blistering condition that typically affects elderly people. AIM: To undertake a national clinical audit based on standards derived from the British Association of Dermatologists (BAD) clinical guidelines on the management of BP. METHODS: In 2018, BAD members were invited to submit data for five consecutive adults with BP per centre, who had been under hospital supervision for at least 12 months, in a national audit over an 11-week period. RESULTS: In total, 123 responders from 120 hospitals provided data for 524 cases. Diagnosis was made either clinically (10.7%; 56 of 524) or through histology with direct immunofluorescence (41.6%; 218 of 524), indirect immunofluorescence (10.3%; 54 of 524) or both (37.4%; 196 of 524). Most patients had very mild baseline disease (63.9%; 225 of 352) with 21.9% (77 of 352) considered mild, 9.8% (31 of 352) moderate and 5.4% (19 of 352) severe. Documentation of diabetes, glycated haemoglobin (HbA1c), blood pressure and hypertension was available for 54.1% (283 of 523), 51% (267 of 524), 44.2% (231 of 522) and 61.5% (321 of 522) of cases, respectively. Oral corticosteroids were commenced in 85.5% (448 of 524) of patients, with 38.4% (172 of 448) of these having documented risk of osteoporosis; data regarding prescription of bone-protection therapies were available for 99.7% (447 of 448) of cases, with 75.6% (338 of 447) of these having a bone-protection prescription. Patient satisfaction was documented in 59.3% (310 of 523) of cases. Systemic treatment was commenced in 95.9% (502 of 524) of cases during the 12-month assessment period, with baseline blood test and follow-up data available for 96.6% (485 of 502) and 95.6% (480 of 502), respectively. Documentation of baseline blood tests was available for 87.4% (424 of 485) of cases, with follow-up tests recorded in 69.8% (335 of 480). CONCLUSION: Overall, compliance with elements of documentation was moderate or low, whereas standards pertaining to direct care were high.

British Association of Dermatologists (BAD) National Audit on Non-Melanoma Skin Cancer Excision 2016 in collaboration with the Royal College of Pathologists.

BACKGROUND: We conducted a re-audit of the surgical practice of UK dermatologists for the treatment of nonmelanoma skin cancer and examined changes with reference to our previous audit in 2014. The audit was supplemented by a detailed assessment of completeness of the histopathology reports for each tumour. METHODS: UK dermatologists collected data on 10 consecutive nonmicrographic excisions for basal cell carcinoma (BCC) and 5 for squamous cell carcinoma (SCC). Data were collected on site, preoperative diagnosis, histological diagnosis, proximity to previous scars, and histological deep and peripheral margins. RESULTS: In total, 222 responses were received from 135 centres, reporting on 3290 excisions. Excisions from the head and neck accounted for 56.7% of cases. Tumour diameter (mean ± SD) was 11.4 ± SD 7.1 mm (maximum size 100 mm) and 97% of cases were primary excisions. BCCs and SCCs respectively accounted for 65.7% and 26.8% of total cases. Of the suspected BCCs and SCCs, 95.8% and 80.4%, respectively, were confirmed histologically. All margins for any tumour were clear in 97.0% of cases, and complication rate in the audit was < 1%. Of the 2864 histology reports evaluated, only 706 (24.6%) contained all core data items; 95% of these were structure (synoptic) reports. Commonly omitted items were level of invasion, risk and T stage, which were absent from 35.7%, 64.2% and 44.1% of reports, respectively. CONCLUSIONS: Diagnostic accuracy and complete excision rates remain high. Complication rates may be under-reported owing to lack of follow-up. Histopathology reporting has a greater chance of being complete if reports are generated on a field-based platform (synoptic reporting).

Adverse effects of topical photodynamic therapy: a consensus review and approach to management.

BACKGROUND: Topical photodynamic therapy (PDT) is widely used to treat superficial nonmelanoma skin cancer and dysplasia, and is generally well tolerated. However, as with all treatments, adverse effects may occur and awareness may facilitate approaches to prevention and management. OBJECTIVES: To review the available evidence relating to the adverse effects of topical PDT, to help inform recommendations in updated clinical guidelines produced by the British Association of Dermatologists and British Photodermatology Group, and the efficacy of preventative and therapeutic approaches. METHODS: This review summarizes the published evidence related to the adverse effects of topical PDT and attempts to interpret this evidence in the context of patient risk and management. RESULTS: Pain and discomfort during PDT are acute adverse effects, which can be minimized through the use of modified and low-irradiance PDT regimens and do not therefore usually limit successful treatment delivery. Other adverse effects include the risk of contact allergy to photosensitizer prodrugs, although this is rare but should be kept in mind, particularly for patients who have received multiple PDT treatments to larger areas. There are no other significant documented longer-term risks and, to date, no evidence of cumulative toxicity or photocarcinogenic risk. CONCLUSIONS: Topical PDT is usually well tolerated, reinforcing the utility of this important therapeutic option in dermatology practice. The main acute adverse effect of pain can typically be minimized through preventative approaches of modified PDT regimens. Other adverse effects are uncommon and generally do not limit treatment delivery.

The new 8th edition of TNM staging and its implications for skin cancer: a review by the British Association of Dermatologists and the Royal College of Pathologists, U.K.

The 8th edition of TNM (tumour, node and metastasis) has numerous and important changes compared with the 7th edition. Public Health England and the Royal College of Pathologists, U.K., have adopted the 8th edition of TNM (TNM8) published by the Union for International Cancer Control for skin cancer staging. These changes will have an impact on the management and commissioning of melanoma and nonmelanoma skin cancer (NMSC). The T1-T3 categories for NMSC staging require the clinician to measure the maximum dimension (usually diameter) of every potential invasive cancer. For squamous, basal and adnexal carcinomas, but not Merkel cell carcinoma (MCC), the T1-T3 categories are defined by new 20-mm and 40-mm divisions based on the maximum dimension of the lesion. In addition, new risk factors upstage T1 or T2 to T3. For melanoma, mitotic index no longer influences separation of pathological stage (pT1). There is a new, additional stratification level at 0·8-mm Breslow thickness. Subdivision pT1b, with a negative sentinel lymph node biopsy (SLNB) of pN0, is now stage IA compared with the previous IB. For MCC, SLNB is now included specifically in the pN staging system. The pT1 subdivision requires clinical information as to whether histologically involved nodes were clinically occult or detectable. For both melanoma and MCC the clinician must state whether the lymph nodes are occult or clinically detectable. Eyelid carcinoma continues to have a staging system different from that in general skin and the system is substantially revised in TNM8.

Conventional and combination topical photodynamic therapy for basal cell carcinoma: systematic review and meta-analysis.

BACKGROUND: Topical photodynamic therapy (PDT) is an established treatment option for low-risk basal cell carcinoma (BCC). OBJECTIVES: To compare efficacy, cosmesis and tolerability of PDT for BCC with alternative treatments. METHODS: MEDLINE, PubMed, Embase and CENTRAL databases were searched from inception until 1 September 2017. Included studies were randomized controlled trials (RCTs) of PDT for nodular (n) and superficial (s) BCC reporting at least one of the following outcomes: clearance at 3 months and sustained at 1 or 5 years; recurrence at ≥ 1 year; cosmesis; adverse events; tolerability. RESULTS: From 2331 search results, 15 RCTs (2327 patients; 3509 BCCs) were included. PDT efficacy (5-year sustained clearance) was high but inferior to excisional surgery [nBCC pooled risk ratio (RR) 0·76; 95% confidence interval (CI) 0·63-0·91], and without re-treatment of partially responding lesions, was modestly inferior to imiquimod (sBCC: RR 0·81; 95% CI 0·70-0·95) and similar to fluorouracil (sBCC: RR 0·88; 95% CI 0·75-1·04). Five-year sustained clearance was inferior with conventional vs. fractionated PDT (sBCC: RR 0·76; 95% CI 0·68-0·84). PDT cosmesis was superior to surgery (sBCC: RR 1·68, 95% CI 1·32-2·14; nBCC: RR 1·82, 95% CI 1·19-2·80) and cryosurgery (BCC: RR 3·73, 95% CI 1·96-7·07), and without re-treatment of partially responding lesions was similar to imiquimod (sBCC: RR 1·01, 95% CI 0·85-1·19) and fluorouracil (sBCC: RR 1·04, 95% CI 0·88-1·24). Peak pain was higher but of shorter duration with PDT than topical treatments. Serious adverse reactions were rarer with PDT than imiquimod (sBCC: RR 0·05, 95% CI 0·00-0·84) and fluorouracil (sBCC: RR 0·11, 95% CI 0·01-2·04). Combination PDT regimens demonstrated reduced recurrence and improved cosmesis; however, results from these small studies were often nonsignificant. CONCLUSIONS: PDT is an effective treatment for low-risk BCC, with excellent cosmesis and safety. Imiquimod has higher efficacy than single-cycle PDT but more adverse effects. Highest efficacy is with excisional surgery. Fractionated and combination PDT options warrant further study.

Compliance with national guidelines on isotretinoin: where are we 2 years since the last audit? Results of the National Isotretinoin Re-Audit 2014.

BACKGROUND: In 2010, the British Association of Dermatologists (BAD) published clinical guidelines for the safe introduction and continued use of isotretinoin in patients with acne in the UK. The BAD provides UK dermatologists with a facility for national audit, and it undertook an audit on compliance with these guidelines in 2012. AIM: To determine current clinical practices relating to use of isotretinoin among dermatologists in the UK (including geographical variations) as measured against BAD standards, and to ascertain any improvement since the 2012 audit. METHODS: The 2012 isotretinoin audit proforma was used, with additional questions on clinical setting, complaints and litigation. A web-based survey tool was used for data entry and submission, with email invitation to working, UK-based BAD members (n = 1226) in December 2013 and weekly reminders during the 8.5-week data collection period. Responders were requested to enter data for the three most recent consecutive patients (including one male and one female patient) who had completed treatment within the previous 6 months. RESULTS: In total, 338 (27.6%) respondents provided data on 1013 patients. Serum lipids were checked in 93.4% of patients and documentation of mental health and/or mood state was recorded in 82.1%. Regarding the Pregnancy Prevention Programme (PPP), 91.6% of female patients of childbearing potential had signed the PPP information form, while 93.3% who had followed the PPP had taken pregnancy tests both before and during treatment, and 54.7% had taken a pregnancy test 5 weeks post-treatment. CONCLUSION: Overall, there is currently good compliance with standards. Certain aspects of care that are less frequently preformed, such as pregnancy testing post-treatment, are highlighted.

British Association of Dermatologists' national audit on nonmelanoma skin cancer excision, 2014.

BACKGROUND: Diagnosis and management of nonmelanoma skin cancer (NMSC) represents a large part of the dermatology workload, and complete excision is a required surgical standard for treatment. AIM: To conduct an audit of the surgical practice for the treatment of NMSC by dermatologists in the UK. METHODS: Data on 10 consecutive nonmicrographic excisions of nonmelanoma skin cancer by UK dermatologists. Data collected included site, preoperative diagnosis, histological diagnosis, proximity to previous scars, and histological deep and peripheral margins. RESULTS: A total of 227 responses from 135 centres reported 2739 excisions. Excisions on the head and neck accounted for 58.3% of cases. Tumour diameter (mean ± SD) was 10.61 ± 6.9 mm (maximum 130 mm), and 96.7% of cases were primary excisions, with 3.3% being re-excisions. Basal cell carcinomas (BCCs) accounted for 79.1% (n = 2167) of the total cases and squamous cell carcinomas (SCCs) for 17.9% n = 491). Of the suspected BCCs and SCCS, 94.4% (n = 2045) and 66.8% (328), respectively, were confirmed histologically to be the respective carcinomas. Similar proportions of BCC and SCC cases were within 10 mm of a previous excision. Lateral and deep margins were clear in 98.3% and 99.2% of BCC cases, respectively, and in 98.4% and 97.1% of SCC cases, respectively. Reported surgical complication rate in the audit was 3.4%. CONCLUSIONS: The majority of excisions for NMSC are for BCC and SCC. Our figures for diagnostic accuracy are at the upper range of previously published figures. Most patients were not followed up in secondary care, hence complication rates may be under-reported.
