Antibiotic adherence in dermatologic surgery: a Multicenter prospective cohort study.

Understanding patient non-adherence to prescribed antibiotics can inform clinical practices, patient counseling, and antibiotic efficacy study design in dermatology. The primary objective was to determine the rate of and reasons for antibiotic non-adherence in the dermatologic surgery setting. The secondary objective was to test the applicability of previously studied survey questions for antibiotic non-adherence screening in the dermatologic surgery setting. Five academic outpatient dermatologic surgery centers across the United States conducted one multicenter prospective cohort study. Dermatologic surgery patients ≥ 18 years of age who were prescribed an antibiotic were included as part of this study. 15.2% (42/276) of patients did not adhere to their antibiotic regimen after dermatologic surgery. Most common reasons for incomplete antibiotic courses included forgotten antibiotics (42.9%,18/42) and side effects (28.6%, 12/42). Previously evaluated questions to identify and predict non-adherence had modest performance in the dermatologic surgery setting (Area under the curve of 0.669 [95% CI (0.583-0.754)]). Antibiotic non-adherence after skin surgery is prevalent and commonly due to reasons that physicians can address with patients.

Anticipated Versus Unanticipated Incomplete Mohs Micrographic Surgery for Keratinocyte Carcinomas: Impact on Treatment Delays and Final Margin Status.

BACKGROUND: Mohs micrographic surgery may be discontinued with positive margins as an anticipated strategy for multidisciplinary care or as an unanticipated occurrence. Management of primary tumors has not been compared after anticipated versus unanticipated incomplete Mohs micrographic surgery (iMMS). OBJECTIVE: To compare rates and timing of adjuvant surgery after iMMS and final margin status when iMMS is anticipated versus unanticipated. Secondary outcomes were preoperative and intraoperative clinicopathologic factors associated with iMMS. METHODS: Cases of iMMS of keratinocyte carcinomas at a tertiary academic center between 2005 and 2022 were classified as anticipated (preoperative assembly of multidisciplinary teams) or unanticipated (ad hoc management of positive margins). Rate, timing, and final margin status of adjuvant surgery was compared between anticipated and unanticipated iMMS cohorts using χ2/Fisher exact test for categorical variables and t-test for continuous variables. RESULTS: Of 127 iMMS cases, 51.2% (65/127) were anticipated. Anticipated iMMS cases were more likely to undergo additional resection (98.5% vs 72.6%, p < .001), with fewer delays (3.9 vs 13.2 days, p < .001) and higher rates of final margin clearance (84.6% vs 59.7%, p < .001). CONCLUSION: When iMMS is anticipated as part of multidisciplinary care, patients are more likely to undergo additional resection, with fewer delays to next surgery and higher final margin clearance rates.

Patient Preferences for Pain Control After Mohs Micrographic Surgery: A Single-Center Discrete Choice Experiment.

Importance: Patient preferences for pain medications after Mohs micrographic surgery are important to understand and have not been fully studied. Objective: To evaluate patient preferences for pain management with only over-the-counter medications (OTCs) or OTCs plus opioids after Mohs micrographic surgery given varying levels of theoretical pain and opioid addiction risk. Design, Setting, and Participants: This prospective discrete choice experiment was conducted in a single academic medical center from August 2021 to April 2022 among patients undergoing Mohs surgery and their accompanying support persons (≥18 years). A prospective survey was administered to all participants using the Conjointly platform. Data were analyzed from May 2022 to February 2023. Main outcome and measure: The primary outcome was the pain level at which half of the respondents chose OTCs plus opioids equally to only OTCs for pain management. This pain threshold was determined for varying opioid addiction risk profiles (low, 0%; low-moderate, 2%; moderate-high, 6%; high, 12%) and measured via a discrete choice experiment and linear interpolation of associated parameters (pain levels and risk of addiction). Results: Of the 295 respondents (mean [SD] age, 64.6 [13.1] years; 174 [59%] were female; race and ethnicity were not considered) who completed the discrete choice experiment, 101 (34%) stated that they would never consider opioids for pain management regardless of the pain level experienced, and 147 (50%) expressed concern regarding possible opioid addiction. Across all scenarios, 224 respondents (76%) preferred only OTCs vs OTCs plus opioids after Mohs surgery for pain control. When the theoretical risk of addiction was low (0%), half of the respondents expressed a preference for OTCs plus opioids given pain levels of 6.5 on a 10-point scale (90% CI, 5.7-7.5). At higher opioid addiction risk profiles (2%, 6%, 12%), an equal preference for OTCs plus opioids and only OTCs was not achieved. In these scenarios, patients favored only OTCs despite experiencing high levels of pain. Conclusion and relevance: The findings of this prospective discrete choice experiment indicate that the perceived risk of opioid addiction affects the patient's choice of pain medications after Mohs surgery. It is important to engage patients undergoing Mohs surgery in shared decision-making discussions to determine the optimal pain control plan for each individual. These findings may encourage future research on the risks associated with long-term opioid use after Mohs surgery.

Local Recurrence Rates After Excision of Desmoplastic Melanoma: A Systematic Review and Meta-Analysis.

BACKGROUND: Few prospective studies have evaluated local recurrence rates (LRR) after excision of desmoplastic melanoma (DM); however, several retrospective studies have reported high LRR. OBJECTIVE: To determine LRR after excision of DM and evaluate factors affecting LRR. MATERIALS AND METHODS: Systematic review of the PubMed, Embase, and Web of Science databases was performed to identify studies reporting local recurrence after excision of DM with conventional wide local excision (WLE), Mohs micrographic surgery (MMS), or staged excision (SE). Meta-analysis was performed to calculate summary LRR and pooled risk ratios (RR). RESULTS: Literature search identified 4 studies evaluating MMS or SE (total n = 61 DM). 53 studies assessed WLE ( n = 3,080) and were analyzed quantitatively. The overall LRR after WLE of DM was 21% (95% CI, 0.16-0.28; n = 2,308). Local recurrence rate was higher with positive/unknown histologic excision margins (49%, 95% CI, 0.25-0.74; n = 91) versus negative histologic margins (11%, 95% CI, 0.07-0.17; n = 1,075; [ p < .01]). Neurotropism was also associated with increased LRR (RR, 1.79; 95% CI, 1.34-2.38, p < .01; n = 644). CONCLUSION: DM has high LRR after WLE. Local recurrence risk was greatest with positive excision margins, indicating the importance of achieving negative microscopic margins. Greater study of MMS and SE for DM is required.

Patient-Reported Nasal Function and Appearance After Interpolation Flap Repair Following Skin Cancer Resection: A Multicenter Prospective Cohort Study.

Objective: Among patients undergoing two-stage interpolated flap repair of nasal defects, nasal function, and appearance before surgery and at 16 weeks after flap takedown were compared using the Nasal Appearance and Function Evaluation Questionnaire (NAFEQ). Design: Multicenter prospective cohort study. Methods: Adult patients with a nasal skin cancer anticipated to require two-stage interpolation flap repair completed the NAFEQ before surgery, at 1 week after flap placement, 4 weeks after flap takedown, and 16 weeks after flap takedown. Results: One hundred sixty-nine patients were enrolled, with 138 patients completing both presurgical and 16-week post-takedown NAFEQs. Overall NAFEQ score increased by 1.09 points (1.91% improvement, confidence interval [95% CI -0.34 to 2.53]). NAFEQ functional subscale increased by 0.72 points (2.58% increase; 95% CI [0.10-1.35]) and appearance subscale increased by 0.37 points (1.28% improvement, 95% CI [-0.65 to 1.39]). Conclusion: At 16 weeks after flap takedown, patients' perceptions of their nasal function and appearance are similar to or slightly improved when compared with their presurgical assessments.

Bupivacaine to Reduce Pain and Narcotic Use After Mohs Micrographic Surgery.

BACKGROUND: Limited data exists for bupivacaine injection after Mohs micrographic surgery (MMS). OBJECTIVE: Evaluate how bupivacaine affects postoperative pain and narcotic use. MATERIALS AND METHODS: In this multicenter, single-blinded, prospective randomized controlled trial, patients received bupivacaine or saline (placebo) immediately after MMS with flap reconstructions identified by American Academy of Dermatology expert consensus as high-risk for pain and narcotic use. For 48 hours postoperatively, patients logged analgesic use, pain scores (0-10), and whether pain was controlled. RESULTS: One hundred seventy-four patients were included. Narcotic analgesic use was higher in the placebo group during the first 24 hours (odds ratio 2.18; confidence interval [CI]: 1.08-4.41; p = .03), second 24 hours (odds ratio 2.18; CI: 0.91-5.29; p = .08), and 48 hours combined (odds ratio 2.58; CI: 1.28-5.24; p < .01). Pain scores were lower in the bupivacaine group during the first 8 hours (mean difference 1.6; CI: 0.73-2.38; p < .001). Overall analgesic use (narcotic and non-narcotic) and percentage of patients reporting pain under control were similar between groups. There were no significant differences in demographics or surgical characteristics. No adverse events occurred. CONCLUSION: Single-dose bupivacaine decreased postoperative pain and narcotic analgesic use after MMS with reconstructions likely to cause significant pain. Bupivacaine may have a role in postoperative pain management and reducing narcotic use in this population.

A comparison of invasive squamous cell carcinoma greater than 1 year after treatment with 5-fluorouracil, imiquimod, or photodynamic therapy with aminolevulinic acid.

BACKGROUND: Studies comparing 5-fluorouracil (5-FU), imiquimod, and photodynamic therapy with aminolevulinic acid (PDT-ALA) have evaluated the efficacy of destroying actinic keratosis (AK). However, this end point may not directly translate to cutaneous squamous cell carcinoma (cSCC) prevention. No study to date has evaluated these field therapies for cSCC prevention in the long term, defined as greater than 1-year posttreatment. OBJECTIVE: Determine the time to surgically treat invasive cSCC development after treatment with 5-FU, imiquimod, or PDT-ALA beginning 1-year posttreatment. METHODS: Retrospective cohort study using the Optum Clinformatics Data Mart database from 2012 to 2019 RESULTS: The rate of cSCC development in patients treated with 5-FU showed no significant difference compared with imiquimod (0.99; 95% CI, 0.90-1.08). PDT-ALA was worse than 5-FU (1.27; 95% CI, 1.19-1.36) and imiquimod (HR, 1.29; 95% CI, 1.17-1.43). Other known predictors of cSCC were consistent with previous literature. LIMITATIONS: The location of field therapy could not be determined with a claims database. CONCLUSIONS: 5-FU is not superior to imiquimod beginning 1 year posttreatment, despite previously demonstrated superior AK destruction efficacy, but was superior to PDT-ALA. Conflating AK destruction and cSCC prevention efficacy may not be appropriate. Future prospective studies should aim to use an end point of cSCC development.

Rates of Opioid Prescriptions Obtained After Mohs Surgery: A Claims Database Analysis From 2009 to 2020.

IMPORTANCE: To curtail the opioid epidemic, physicians have been advised to limit opioid prescriptions. OBJECTIVE: To characterize the frequency and changes over time (2009-2020) of opioid prescriptions following Mohs micrographic surgery. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study using Optum Clinformatics DataMart (Optum CDM), a nationally representative insurance claims database, included patients aged 18 years and older who had Mohs micrographic surgery insurance claims in the Optum CDM database from 2009 to 2020. Data were analyzed from November 11, 2020, to March 30, 2021. EXPOSURES: Opioid prescription following Mohs surgery. MAIN OUTCOMES AND MEASURES: The primary outcome was the proportion of patients who underwent Mohs surgery and obtained an opioid prescription within 2 days of surgery. Secondary outcomes included type and opioid quantity prescribed. RESULTS: Among 358 012 patients with Mohs micrographic surgery claims (mean [SD] age, 69 [13] years; 205 609 [57.4%] were men), the proportion of patients obtaining an opioid prescription after Mohs micrographic surgery increased from 2009 (34.6%) to 2011 (39.6%). This proportion then declined each year, reaching a low of 11.7% in 2020 (27.9% absolute decrease from 2011 to 2020). Hydrocodone, codeine, oxycodone, and tramadol were the 4 most commonly prescribed opioids. By 2020, hydrocodone was obtained less (2009: 47.5%; 2011: 67.1%; 2020: 45.4%; 21.7% absolute decrease from 2011 to 2020) and tramadol was obtained more (2009: 1.6%; 2020: 27.9%; 26.3% absolute increase from 2009 to 2020). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of Mohs micrographic surgery claims, patients obtained fewer postsurgery opioid prescriptions over the study period, suggesting responsiveness of patients and dermatologic surgeons to public health concerns regarding the opioid epidemic. During this decline, prescriptions for hydrocodone decreased and tramadol increased.

Patient Quality of Life After Interpolated Flap Repair of Nasal Mohs Surgery Defects: A Multicenter Prospective Cohort Study.

IMPORTANCE: Single-center studies have shown that patients report better skin cancer-specific quality of life (QOL) after Mohs micrographic surgery (MMS), but it is unclear whether this improved QOL applies to patients after MMS and complex reconstruction in cosmetically sensitive areas. OBJECTIVE: To evaluate patient QOL after MMS and interpolation flap reconstruction for patients with nasal skin cancers. DESIGN, SETTING AND PARTICIPANTS: This multicenter prospective survey study used the Skin Cancer Index (SCI), a validated, 15-question QOL questionnaire administered at 4 time points: before MMS, 1 week after flap placement, 4 weeks after flap takedown, and 16 weeks after flap takedown. Patients age 18 years or older with a nasal skin cancer who presented for MMS and were anticipated to undergo 2-stage interpolated flap repair by a Mohs surgeon were recruited from August 9, 2018, to February 2, 2020, at 8 outpatient MMS locations across the United States, including both academic centers and private practices. MAIN OUTCOMES AND MEASURES: Mean difference in overall SCI score before MMS vs 16 weeks after flap takedown. RESULTS: A total of 169 patients (92 men [54.4%]; mean [SD] age, 67.7 [11.4] years) were enrolled, with 147 patients (75 men [51.0%]; mean [SD] age, 67.8 [11.7] years) completing SCI surveys both before MMS and 16 weeks after flap takedown. Total SCI scores improved significantly 16 weeks after flap takedown compared with pre-MMS scores, increasing by a mean of 13% (increase of 7.11 points; 95% CI, 5.48-8.76; P < .001). All 3 SCI subscale scores (emotion, appearance, and social) improved significantly (emotion subscale, increase of 3.27 points; 95% CI, 2.35-4.18; P < .001; appearance subscale, increase of 1.65 points; 95% CI, 1.12-2.18; P < .001; and social subscale, increase of 2.10 points; 95% CI, 1.55-2.84; P < .001) 16 weeks after flap takedown compared with pre-MMS. CONCLUSIONS AND RELEVANCE: Removal of a nasal skin cancer and repair of the resulting defect can be distressing for patients. However, this cohort study suggests that physicians referring patients for MMS can be reassured that their patient's QOL will improve on average after surgery, even when a complex reconstruction is required.

Supporting Underrepresented in Medicine (UIM) and non-UIM Trainees Applying into Dermatology: A Qualitative Analysis.

BACKGROUND: Recently, there have been calls to improve diversity among the dermatology workforce, with emphasis placed on the resident selection process and trainee pipeline. However, there is limited data on the perspectives of dermatology applicants, especially among UIM trainees, and the support that they need and want to successfully apply in dermatology. METHODS: To assess trainee perspectives, we disseminated a survey to medical students, interns (matched into dermatology), and dermatology residents asking how dermatology residency programs can best support trainees through the dermatology application process. We developed a codebook drawing upon grounded theory methodology, and consensus coded all qualitative responses. RESULTS: We received 224 qualitative responses from underrepresented in medicine (UIM) (65, 29.0%) and non-UIM trainees (159, 70.9%). UIM trainees were more likely to mention diversity and inclusion initiatives (46.2% vs 3.8%, P<0.001), transparency in program information (40.0% vs 24.5%, P=0.021), holistic review (30.8% vs 6.3%, P<0.001), UIM student outreach/pipeline programs (23.1% vs 0.6%, P<0.001), and mentorship (21.5% vs 8.2%, P=0.009). CONCLUSION: Improving programmatic efforts to address unique challenges UIM trainees face when applying into dermatology is instrumental to mitigating barriers. We highlight opportunities for dermatology residency programs to create a more fair and equitable dermatology application process and support a more diverse pipeline of future dermatologists.
