Identifying critical quality metrics in Mohs Surgery: A national expert consensus process.

BACKGROUND: Amid a movement toward value-based healthcare, increasing emphasis has been placed on outcomes and cost of medical services. To define and demonstrate the quality of services provided by Mohs surgeons, it is important to identify and understand the key aspects of Mohs micrographic surgery (MMS) that contribute to excellence in patient care. OBJECTIVE: The purpose of this study is to develop and identify a comprehensive list of metrics in an initial effort to define excellence in MMS. METHODS: Mohs surgeons participated in a modified Delphi process to reach a consensus on a list of metrics. Patients were administered surveys to gather patient perspectives. RESULTS: Twenty-four of the original 66 metrics met final inclusion criteria. Broad support for the initiative was obtained through physician feedback. LIMITATIONS: Limitations of this study include attrition bias across survey rounds and participation at the consensus meeting. Furthermore, the list of metrics is based on expert consensus instead of quality evidence-based outcomes. CONCLUSION: With the goal of identifying metrics that demonstrate excellence in performance of MMS, this initial effort has shown that Mohs surgeons and patients have unique perspectives and can be engaged in a data-driven approach to help define excellence in the field of MMS.

5-Year Follow-Up of a Physician Performance Feedback Report Intervention to Reduce Overuse and Excess Cost: A National Cohort Study.

BACKGROUND: Mohs micrographic surgery efficiently treats skin cancer through staged resection, but surgeons' varying resection rates may lead to higher medical costs. OBJECTIVE: To evaluate the cost savings associated with a quality improvement. MATERIALS AND METHODS: The authors conducted a retrospective cohort study using 100% Medicare fee-for-service claims data to identify the change of mean stages per case for head/neck (HN) and trunk/extremity (TE) lesions before and after the quality improvement intervention from 2016 to 2021. They evaluated surgeon-level change in mean stages per case between the intervention and control groups, as well as the cost savings to Medicare over the same time period. RESULTS: A total of 2,014 surgeons performed Mohs procedures on HN lesions. Among outlier surgeons who were notified, 31 surgeons (94%) for HN and 24 surgeons (89%) for TE reduced their mean stages per case with a median reduction of 0.16 and 0.21 stages, respectively. Reductions were also observed among outlier surgeons who were not notified, reducing their mean stages per case by 0.1 and 0.15 stages, respectively. The associated total 5-year savings after the intervention was 92 million USD. CONCLUSION: The implementation of this physician-led benchmarking model was associated with broad reductions of physician utilization and significant cost savings.

Mohs micrographic surgery and dermatopathology concordance: An analysis of 1421 Mohs cases over 17 years.

BACKGROUND: The success of Mohs micrographic surgery depends on the surgeon's ability to correctly interpret intraoperative frozen sections. OBJECTIVE: This retrospective study analyzed the rate of concordance between Mohs surgeons and dermatopathologists in reading slides from Mohs surgery cases. METHODS: A dermatopathologist reviewed all the frozen sections and the corresponding Mohs map for every 30th Mohs case at a practice employing 6 different Mohs surgeons during 2001-2017. Cases in which the dermatopathologist and the Mohs surgeon disagreed on the interpretation were noted. RESULTS: The concordance rate between Mohs surgeons and dermatopathologists was 99.79%. The 3 discordant cases included a case of squamous cell carcinoma, a case of superficial basal cell carcinoma, and a case of hypertrophic squamous cell carcinoma in situ. LIMITATIONS: This analysis is limited to fellowship-trained Mohs surgeons and, therefore, might not be applicable to all physicians who perform Mohs. CONCLUSION: Fellowship-trained Mohs surgeons show high concordance with board-certified dermatopathologists in the accurate and precise interpretation of histology slides in the setting of Mohs micrographic surgery.

Well-Being and Professional Fulfillment in Mohs Surgeons: An Explanatory Sequential Mixed-Method Design Study.

BACKGROUND: There are limited data evaluating specific themes of well-being and professional fulfillment in Mohs surgeons. OBJECTIVE: To identify factors that drive occupational distress and those that promote well-being and professional fulfillment among Mohs surgeons. METHODS: This is an explanatory sequential mixed-method study, using semistructured individual interviews. Common drivers of physician well-being and fulfillment were identified based on the independent assessment of the coding in the interview transcripts. RESULTS: This study reports the following qualitative themes: (1) gratitude for the chosen profession and relationships, (2) unrealistic standards of perfection that may have contributed to past career success but are unattainable and create emotional burden, and (3) ability to practice in a manner aligned with personal values promotes professional fulfillment. CONCLUSION: This study suggests that gratitude, self-compassion, and ability to practice in a manner aligned with personal values promote well-being and professional fulfillment in Mohs surgeons. Notably, we found that unrealistic standards of perfection and personal-organization practice incongruences contribute to burnout.

Postoperative Complications After Interpolated Flap Repair for Mohs Defects of the Nose: A Multicenter Prospective Cohort Study.

BACKGROUND: Dermatologists perform most interpolated flaps after skin cancer resection. Prospective, multicenter data on complications after interpolated flap repair in this setting are limited. OBJECTIVE: To determine the rate of physician-reported complications after interpolated flap repair of the nose. METHODS: Multicenter, prospective cohort study of 169 patients undergoing 2-stage interpolated flap repair of post-Mohs nasal defects. Frequency of bleeding, infection, dehiscence, necrosis, hospitalization, and death in the 30 days after flap placement and flap takedown are reported. RESULTS: Patients experienced 23 complications after flap placement (13.61%) and 6 complications after flap takedown (3.55%) that were related to the surgical procedure. The most frequent complication after flap placement was bleeding (9, 5.33%, 95% confidence interval [CI]: 2.83%-9.82%). The most frequent complication after flap takedown was infection (5, 2.96%, 95% CI: 1.27%-6.74%). There was one hospitalization related to an adverse reaction to antibiotics. There were no deaths. CONCLUSION: Most complications after interpolated flap repair for post-Mohs defects of the nose are minor and are associated with flap placement. Interpolated flap repair for post-Mohs defects can be performed safely in the outpatient setting under local anesthesia.

Evidence-based clinical practice guideline: Reconstruction after skin cancer resection.

A multi-disciplinary work group involving stakeholders from various backgrounds and societies was convened to develop guidelines for the management of reconstruction after skin cancer resection. The goal was to identify areas of common ground and provide evidence-based recommendations to improve patient care. Given the heterogeneity of reconstructive techniques and clinical scenarios, investigation centered around common elements in the process. In some cases, a distinction was made between treatment options in the office-based setting as opposed to those in the facility setting. A systematic literature review was performed, and an established appraisal process was used to rate the quality of relevant scientific research (Grading of Recommendations Assessment, Development, and Evaluation methodology). Final recommendations are related to concepts concerning the timing of reconstruction, management of anticoagulation, use of antibiotics, methods of pain control, and follow-up assessment. At times, there was insufficient evidence to make high-level recommendations. The literature analysis highlights the need for additional methodologically robust studies in this area, to help guide clinical practice.

A process evaluation of the improving wisely intervention: a peer-to-peer data intervention to reduce overuse in surgery.

BACKGROUND: The Improving Wisely intervention is a peer-to-peer audit and feedback intervention to reduce overuse of Mohs Micrographic Surgery (MMS). The objective of this study was to conduct a process evaluation to evaluate Mohs surgeons' perceptions of the implementation quality and perceived impact of the Improving Wisely intervention. METHODS: Surgeons in the Improving Wisely intervention arm, comprised of members of the American College of Mohs Surgeons (ACMS) who co-led the intervention, were invited to complete surveys and key informant interviews. Participants described perceptions of implementation quality (evaluated via dose, quality of implementation, reach and participant responsiveness), perceived impact of the Improving Wisely intervention (evaluated on a 1-5 Likert and qualitatively), and barriers and facilitators to changing surgeons' clinical practice patterns to reduce Mohs overuse. RESULTS: Seven hundred thirty-seven surgeons participated in the survey. 89% were supportive of the intervention. Participants agreed that the intervention would improve patient care and reduce the annual costs of Mohs surgery. Thirty surgeons participated in key informant interviews. 93% were interested in receiving additional data reports in the future. Participants recommended the reports be disseminated annually, that the reports be expanded to include appropriateness data, and that the intervention be extended to non ACMS members. Six themes identifying factors impacting potential MMS overuse were identified. CONCLUSIONS: Participants were strongly supportive of the intervention. We present the template used to design and implement the Improving Wisely intervention and provide suggestions for specialty societies interested in leading similar quality improvement interventions among their members.

An expert panel consensus on opioid-prescribing guidelines for dermatologic procedures.

BACKGROUND: Opioid overprescribing is a major contributor to the opioid crisis. The lack of procedure-specific guidelines contributes to the vast differences in prescribing practices. OBJECTIVE: To create opioid-prescribing consensus guidelines for common dermatologic procedures. METHODS: We used a 4-step modified Delphi method to conduct a systematic discussion among a panel of dermatologists in the fields of general dermatology, dermatologic surgery, and cosmetics/phlebology to develop opioid prescribing guidelines for some of the most common dermatologic procedural scenarios. Guidelines were developed for opioid-naive patients undergoing routine procedures. Opioid tablets were defined as oxycodone 5-mg oral equivalents. RESULTS: Postoperative pain after most uncomplicated procedures (76%) can be adequately managed with acetaminophen and/or ibuprofen. Group consensus identified no specific dermatologic scenario that routinely requires more than 15 oxycodone 5-mg oral equivalents to manage postoperative pain. Group consensus found that 23% of the procedural scenarios routinely require 1 to 10 opioid tablets, and only 1 routinely requires 1 to 15 opioid tablets. LIMITATIONS: These recommendations are based on expert consensus in lieu of quality evidence-based outcomes research. These recommendations must be individualized to accommodate patients' comorbidities. CONCLUSIONS: Procedure-specific opioid prescribing guidelines may serve as a foundation to produce effective and responsible postoperative pain management strategies after dermatologic interventions.

Mohs Micrographic Surgery Pearls for the Nose and Lips.

BACKGROUND: Failure to perform Mohs micrographic surgery (MMS) meticulously on the nose and lips can lead to larger defects and tumor recurrence, which can have aesthetic and functional repercussions for patients. OBJECTIVE: To review pre-, intra-, and postoperative techniques and pearls for performing MMS on the nose and lips to optimize outcomes. MATERIALS AND METHODS: Technical nuances and pearls cultured from the authors' own practice, those acquired from mentors and colleagues, and information identified from the literature are discussed to provide a logical approach to performing effective MMS on the nose and lips. RESULTS: When performing MMS on the nose and lips, sound preoperative preparation, precise surgical technique, and particular attention to reducing false-positives and false-negatives while harvesting Mohs layers enhances the fidelity of the MMS procedure, minimizing defect sizes and reducing tumor recurrence. CONCLUSION: Refining Mohs technique on the nose and lips allows more effective performance of tumor extirpation, improved microscopic evaluation, and more conservative reconstruction, leading to better patient outcomes.

The suspension (Frost) suture: experience and applications.

BACKGROUND: The Frost suture is a well-known surgical technique for providing upward tension on the lower lid to prevent or correct ectropion after surgical interventions in the periorbital area. Despite its relatively common use, comprehensive information on executing this technique is not readily available. OBJECTIVE: To review eyelid anatomy, indications, and proper technique for performing the Frost suture, as well as potential complications. MATERIALS AND METHODS: A review of the literature on Frost sutures was performed. Cadaveric dissection was performed to demonstrate placement of the Frost suture. RESULTS AND CONCLUSION: The Frost suture is a useful method to reduce the risk of ectropion after surgery near the lower eyelid. Downward pull on the lid can occur with normal wound contracture even if ectropion is not present with the initial repair, reinforcing the need for preventive measures. Potential complications of this technique include superficial skin erosion of the upper lid, corneal abrasion, and blockage of the field of vision while the suture is in place.

Recurrent Atypical Fibroxanthoma Versus Malignant Fibrous Histiocytoma.

Atypical fibroxanthoma (AFX) has been characterized variously as a benign noninvasive neoplasm with rare recurrence. We report 2 cases of recurrent AFX. There is ongoing controversy over the diagnosis of AFX versus malignant fibrous histiocytoma (MFH) in the clinical context of recurrent AFX. Histopathologic diagnosis of fibrohistiocytic neoplasms can be quite challenging and small foci of cancer can be easily overlooked. This is particularly problematic when scarring associated with recurrent tumors is present. The utility of en face sections, as utilized in Mohs micrographical surgery, and the employment of immunohistochemical stains may be helpful in diagnosis. Recurrence of AFX can occur but is difficult to distinguish from MFH.

Paramedian forehead flap: advances, procedural nuances, and variations in technique.

BACKGROUND: The paramedian forehead flap (PFF) is a well-established technique for reconstruction of large nasal defects. The literature has provided several technical advances and procedural nuances that expand the surgeon's options when performing this procedure. OBJECTIVE: The objective is to provide procedural nuances, technical tips, and suggestions for improving flap outcomes. Specific techniques such as extending flap length below the orbital rim, avoiding terminal scalp hair inclusion in the flap design, restoring lining to full-thickness defects, and even flap dressings and wound care are detailed here. Of particular importance, the 3-staged turnover forehead flap for wounds requiring nasal lining, with delayed flap sculpting and cartilage graft placement, has revolutionized the conceptual approach to the most complicated nasal defects, and the technique is described in detail. METHODS: This article includes the techniques and approaches from 3 different surgeons at 3 different institutions with 3 different training backgrounds, in an effort to provide a nuanced and broad overview of the subject matter. RESULTS AND CONCLUSION: The PFF technique has been refined with increasing procedural variations and nuances in technique. The nasal reconstructive surgeon, armed with knowledge of these techniques, can approach each patient with a broad knowledge base and perform reconstruction with maximum success.

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.

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.

Trilobed flap reconstruction for distal nasal skin defects.

BACKGROUND: The bilobed flap is reliable for reconstruction of Mohs defects on the lower third of the nose. It uses skin from the proximal nose to reconstruct defects of the nasal tip and ala. The goal is to avoid alar rim displacement and asymmetry. The trilobed flap's design and execution leverage the strengths of the bilobed flap to allow application to a broader range of surgical nasal defect sizes and locations, particularly distal defects. OBJECTIVE: To present our surgical execution and application of the trilobed flap for reconstruction of distal nasal Mohs surgery defects. METHODS AND MATERIALS: Mohs surgery defects of the distal nose of 31 patients were reconstructed using a trilobed flap over a 3-year period. Pre- and postoperative photographs were independently and blindly evaluated and graded for alar symmetry and overall cosmesis. RESULTS: Median alar symmetry and overall cosmesis scores based on three reviewers were excellent. CONCLUSION: The trilobed flap offers a successful reconstructive option for Mohs defects of the distal nose that may not be optimally amenable to bilobed flap repair. Over 3 years, 31 trilobed flap repairs were performed with overall excellent outcomes.
