Reported Outcome Measures in Mohs Micrographic Surgery in Studies With Defined Techniques for Embedding and Processing of Tissue: A Systematic Review.

BACKGROUND: Mohs micrographic surgery (MMS) is a technique that combines surgical excision and histologic evaluation to achieve higher cure rates for skin cancer than traditional surgical excision. Competing performance measures have fostered numerous histologic techniques for MMS. OBJECTIVE: To analyze differences in primary outcomes in the published literature regarding the technique of tissue processing and embedding during the MMS process. METHODS: A systematic review was performed of the published literature in MEDLINE, PubMed, Embase, and Cochrane library that included a description of the manipulation of tissue during the grossing and embedding steps of MMS. RESULTS: Inclusion criteria were met by 61 articles. Of these studies, the cure/recurrence rate was assessed in 1 article (1.6%), tissue conservation was assessed in 47 (77%), time-saving was assessed in 35 (57%), cost-saving was assessed in 6 (10%), and decreased artifact were assessed in 20 (33%). CONCLUSION: There is a lack of standardization for assessing clinical outcomes in the published literature regarding MMS process techniques. Cure is a critical outcome in studies comparing MMS processing methodologies.

Pain Intensity Assessment Scales for Dermatologic Surgery Patients: A Systematic Review.

BACKGROUND: Pain assessment plays an important role in dermatologic surgery. The numeric rating scale (NRS), visual analog scale (VAS), verbal rating scale (VRS), and Faces Pain Scale (FPS) are commonly used scales for pain measurement. Conflicting evidence exists regarding the use of each. Prompt pain recognition and treatment during procedures result in higher patient satisfaction. OBJECTIVE: Determine the most applicable scale for acute pain measurement in dermatologic surgery. MATERIALS AND METHODS: This systematic review was performed in accordance with PRISMA-Supplemental Digital Content 4, http://links.lww.com/DSS/A976 (PROSPERO; CRD42018091058). PubMed, Cochrane, EMBASE, Scopus, and Web of Science were searched between April 24, 2018, and May 06, 2018. The search query consisted of pain, pain measurement (NRS, VAS, VRS, and FPS), and assessment/comparison. The inclusion criteria included English language literature with primary/secondary outcome objectives directly comparing ≥2 pain scales in acute pain (age: 13+). Study end points included interscale correlations, patient preferences, provider preferences, study author recommendations, and failure rates. RESULTS: Eight hundred seven studies were retrieved: A total of 42 studies were included. The visual analog scale (n = 42) was most studied, followed by NRS (n = 29), VRS (n = 27), and FPS (n = 11). 93.1% studies showed a high statistical correlation between VAS and NRS. Patients preferred NRS (n = 8/11), followed by FPS (n = 3/11), VRS (n = 2/11), and VAS (n = 1/11). Study authors recommended NRS/VAS (n = 8/19), VRS (n = 6/19), and FPS (n = 1/19). Providers preferred NRS (n = 2/3) and VRS (n = 1/3). The visual analog scale had the highest failure rate (n = 11/12). CONCLUSION: The numeric rating scale is most applicable for dermatologic surgery because of reported patient and provider preferences, lowest failure rates, and most frequent study author recommendations.
