Implementing patient safety and quality improvement in dermatology. Part 2: Quality improvement science.

Quality improvement (QI) in medicine is reliant on a team-based approach and an understanding of core QI principles. Part 2 of this continuing medical education series outlines the steps of performing a QI project, from identifying QI opportunities, to carrying out successive Plan-Do-Study-Act cycles, to hard-wiring improvements into the system. QI frameworks will be explored and readers will understand how to interpret basic QI data.

Implementing patient safety and quality improvement in dermatology. Part 1: Patient safety science.

Patient safety (PS) and quality improvement (QI) have gained momentum over the last decade and are becoming more integrated into medical training, physician reimbursement, maintenance of certification, and practice improvement initiatives. While PS and QI are often lumped together, they differ in that PS is focused on preventing adverse events while QI is focused on continuous improvements to improve outcomes. The pillars of health care as defined by the 1999 Institute of Medicine report "To Err is Human: Building a Safer Health System" are safety, timeliness, effectiveness, efficiency, equity, and patient-centered care. Implementing a safety culture is dependent on all levels of the health care system. Part 1 of this CME will provide dermatologists with an overview of how PS fits into our current health care system and will include a focus on basic QI/PS terminology, principles, and processes. This article also outlines systems for the reporting of medical errors and sentinel events and the steps involved in a root cause analysis.

Expediting patient appointments with dermatology rapid access clinics.

BACKGROUND: Lengthy wait times for dermatology appointments in the U.S. limit care access. The University of Pennsylvania's Department of Dermatology has established an urgent care clinic (UCC) and an intermediate care clinic (ICC) to expedite appointments for higher acuity patients. OBJECTIVE: To describe our rapid access clinics' operations, referral patterns, and distributions of diagnoses. METHODS: We performed a retrospective review of dermatology consult order and appointment data for UCC, ICC, and routine care to determine the number of orders, consult appointments, and follow-up appointments; appointment wait times; and frequencies of diagnoses in referring provider and consult appointments. Press Ganey patient satisfaction ratings were also analyzed. RESULTS: The median (interquartile range) wait times for UCC, ICC, and routine care, appointments were 3 (1-8) days, 36 (15-64) days, and 45 (12-97) days, respectively (P<0.001). The proportion of referrals originating from subspecialists varied among UCC (47.6%), ICC (20.2%) and routine care (15.8%), (P<0.001). Distributions of diagnoses differed among UCC, ICC, and routine care. Ratings for most satisfaction metrics were similar across clinic settings. CONCLUSIONS: Dermatology rapid access clinics within an academic medical center can reduce wait times for higher acuity patients while maintaining patient satisfaction.

Primary cutaneous aggressive epidermotropic cytotoxic T-cell lymphomas: reappraisal of a provisional entity in the 2016 WHO classification of cutaneous lymphomas.

Primary cutaneous CD8-positive aggressive epidermotropic T-cell lymphoma is a rare and poorly characterized variant of cutaneous lymphoma still considered a provisional entity in the latest 2016 World Health Organization Classification of Cutaneous lymphomas. We sought to better characterize and provide diagnostic and therapeutic guidance of this rare cutaneous lymphoma. Thirty-four patients with a median age of 77 years (range 19-89 years) presented primarily with extensive annular necrotic plaques or tumor lesions with frequent mucous membrane involvement. The 5-year survival was 32% with a median survival of 12 months. A subset of 17 patients had a prodrome of chronic patches prior to the development of aggressive ulcerative lesions. We identified cases with lack of CD8 or αß T-cell receptor expression yet with similar clinical and pathological presentation. Allogeneic stem cell transplantation provided partial or complete remissions in 5/6 patients. We recommend the term primary cutaneous aggressive epidermotropic cytotoxic T-cell lymphoma as this more broad designation better describes this clinical-pathologic presentation, which allows the inclusion of cases with CD8 negative and/or αß/γδ T-cell receptor chain double-positive or double-negative expression. We have identified early skin signs of chronic patch/plaque lesions that are often misdiagnosed as eczema, psoriasis, or mycosis fungoides. Our experience confirms the poor prognosis of this entity and highlights the inefficacy of our standard therapies with the exception of allogeneic stem cell transplantation in selected cases.

Preoperative telephone consultation does not decrease patient anxiety before Mohs micrographic surgery.

BACKGROUND: Many factors influence anxiety and satisfaction of patients undergoing Mohs micrographic surgery (MMS). OBJECTIVE: We sought to determine the effect of a preoperative educational telephone call on anxiety and satisfaction for patients undergoing same-day office consultation and MMS. METHODS: Patients with skin cancer (N = 104) scheduled for same-day office consultation and MMS were randomly assigned to receive or not to receive an educational telephone call during the week before surgery. All patients rated their anxiety levels immediately before and after the same-day office consultation and MMS by completing the State-Trait Anxiety Inventory and an anxiety visual analog scale. Patients also rated satisfaction immediately after MMS by completing the Visit-Specific Patient Satisfaction Questionnaire. RESULTS: Patients undergoing same-day office consultation and MMS reported similar levels of increased anxiety and high satisfaction, regardless of whether they received a preoperative educational telephone call. LIMITATIONS: Lack of control for patients' prior surgery or self-education is a limitation. CONCLUSION: Preoperative educational telephone calls did not relieve anxiety or improve satisfaction for patients undergoing same-day office consultation and MMS. Preoperative education and counseling has uncertain benefits to anxiety and satisfaction of patients undergoing MMS.

Improvement in peripheral blood disease burden in patients with Sézary syndrome and leukemic mycosis fungoides after total skin electron beam therapy.

BACKGROUND: There is a paucity of effective therapies for patients with Sézary syndrome and advanced mycosis fungoides with peripheral blood involvement. Total skin electron beam (TSEB) radiation therapy is an extremely effective skin-directed therapy for these patients, but, until recently, it was thought not to signifcantly affect the peripheral blood malignant T-cell population. OBJECTIVE: We conducted this study to determine if TSEB has therapeutic effect on the peripheral blood in patients with advanced mycosis fungoides and Sézary syndrome. METHODS: All patients on stable medication regimens seen in our photopheresis facility who received TSEB therapy between January 2008 and October 2011 at Temple University Hospital, Philadelphia, PA, were analyzed retrospectively for improvement in the peripheral blood, as documented by flow cytometry. RESULTS: Six of 11 patients achieved 50% or greater decrease in their peripheral blood malignant T-cell population after TSEB therapy, for an overall response rate of 55%. Within the group of patients who had a response in the skin, 67% also had a response in the peripheral blood. LIMITATIONS: This analysis is limited in 3 ways. First, the sample described is small. Second, the results may be confounded by the fact that each patient was on other systemic therapies in addition to TSEB, albeit stable pre-existing regimens. The time interval between completion of TSEB therapy and repetition of flow cytometry was not standardized among patients, which may result in an underestimation of the overall response to TSEB therapy. CONCLUSION: In patients with advanced mycosis fungoides and Sézary syndrome, the peripheral blood tumor burden may improve after treatment with TSEB.

Cutaneous mantle cell lymphoma presenting as a diffuse morbilliform rash: A case report.

This case describes a patient with known mantle cell lymphoma without cutaneous involvement presenting with a diffuse morbilliform rash during an inpatient admission for bacterial pneumonia. The patient was thought to have a hypersensitivity to antibiotics but failed to improve after the offending agents were stopped. A skin biopsy revealed metastatic cutaneous mantle cell lymphoma. Treatment with high-dose corticosteroids and chemotherapy was initiated resulting in the resolution of the rash.

Peripheral blood findings in erythrodermic patients: importance for the differential diagnosis of Sézary syndrome.

Although Sézary syndrome (SS) represents an advanced stage of cutaneous T-cell lymphoma, this diagnosis presents a challenge even for the most experienced dermatologic clinicians. SS is characterized clinically by erythroderma, but can also be identified in the presence of specific histologic and peripheral blood findings. Erythrodermic cutaneous T-cell lymphoma can mimic a number of nonmalignant disorders with erythroderma, including pityriasis rubra pilaris, psoriasis, atopic dermatitis, and graft-versus-host disease. The diagnosis is made even more challenging because the histology of SS is often nonspecific and rarely pathognomonic. As a result, peripheral blood studies in patients with erythroderma are frequently informative in the diagnosis of SS. Peripheral blood abnormalities including elevated CD4/CD8 ratio, aberrant CD26, CD27 and CD7 expression, and T-cell clonality can all be used to help arrive at a diagnosis. This review evaluates current data on the usefulness and limitations of specific peripheral blood markers detected by flow cytometry and T-cell receptor gene rearrangement polymerase chain reaction.

Association of Persistent Rubella Virus With Idiopathic Skin Granulomas in Clinically Immunocompetent Adults.

Importance: Vaccine-derived and wild-type rubella virus (RuV) has been identified within granulomas in patients with inborn errors of immunity, but has not been described in granulomas of healthy adults. Objective: To determine the association between RuV and atypical granulomatous inflammation in immune-competent adults. Design, Setting, and Participants: This case series, conducted in US academic dermatology clinics from January 2019 to January 2021, investigated the presence of RuV in skin specimens using RuV immunofluorescent staining of paraffin-embedded tissue sections, real-time reverse-transcription polymerase chain reaction, whole-genome sequencing with phylogenetic analyses, and cell culture by the US Centers for Disease Control and Prevention. Rubella immunoglobulin G, immunoglobulin M enzyme-linked immunoassay, and viral neutralization assays were performed for the sera of immunocompetent individuals with treatment refractory cutaneous granulomas and histopathology demonstrating atypical palisaded and necrotizing granulomas. Clinical immune evaluation was performed. Main Outcomes and Measures: Identification, genotyping, and culture of vaccine-derived and wild-type RuV within granulomatous dermatitis of otherwise clinically immune competent adults. Results: Of the 4 total immunocompetent participants, 3 (75%) were women, and the mean (range) age was 61.5 (49.0-73.0) years. The RuV capsid protein was detected by immunohistochemistry in cutaneous granulomas. The presence of RuV RNA was confirmed by real-time reverse-transcription polymerase chain reaction in fresh-frozen skin biopsies and whole-genome sequencing. Phylogenetic analysis of the RuV sequences showed vaccine-derived RuV in 3 cases and wild-type RuV in 1. Live RuV was recovered from the affected skin in 2 participants. Immunology workup results demonstrated no primary immune deficiencies. Conclusions and Relevance: The case series study results suggest that RuV (vaccine derived and wild type) can persist for years in cutaneous granulomas in clinically immunocompetent adults and is associated with atypical (palisaded and necrotizing type) chronic cutaneous granulomas. These findings represent a potential paradigm shift in the evaluation, workup, and management of atypical granulomatous dermatitis and raises questions regarding the potential transmissibility of persistent live RuV.

Impact of COVID-19 on Dermatology Residency.

COVID-19 has created challenges across medicine, including in medical education, with deeply rooted impacts in the dermatology residency experience. Its effects are both acute and chronic, including: shifts to virtual education and conferences, skewed clinical experiences, negatively impacted wellness, and uncertainty in the future. As educators and mentors, it is important to recognize and address these issues so that we may remain transparent, adaptable, and engaged as we continue to build a better tomorrow for our resident trainees.

Granulomatous Dermatitis Associated With Rubella Virus Infection in an Adult With Immunodeficiency.

IMPORTANCE: Immunodeficiency-related, vaccine-derived rubella virus (RuV) as an antigenic trigger of cutaneous and visceral granulomas is a rare, recently described phenomenon in children and young adults treated with immunosuppressant agents. OBJECTIVE: To perform a comprehensive clinical, histologic, immunologic, molecular, and genomic evaluation to elucidate the potential cause of an adult patient's atypical cutaneous granulomas. DESIGN, SETTING, AND PARTICIPANTS: A prospective evaluation of skin biopsies, nasopharyngeal swabs, and serum samples submitted to the Centers for Disease Control and Prevention was conducted to assess for RuV using real-time reverse-transcriptase polymerase chain reaction (RT-PCR) and viral genomic sequencing. The samples were obtained from a man in his 70s with extensive cutaneous granulomas mimicking both cutaneous sarcoidosis (clinically) and CD8+ granulomatous cutaneous T-cell lymphoma (histopathologically). The study was conducted from September 2019 to February 2021. MAIN OUTCOMES AND MEASURES: Identification and genotyping of a novel immunodeficiency-related RuV-associated granulomatous dermatitis. RESULTS: Immunohistochemistry for RuV capsid protein and RT-PCR testing for RuV RNA revealed RuV in 4 discrete skin biopsies from different body sites. In addition, RuV RNA was detected in the patient's nasopharyngeal swabs by RT-PCR. The full viral genome was sequenced from the patient's skin biopsy (RVs/Philadelphia.PA.USA/46.19/GR, GenBank Accession #MT249313). The patient was ultimately diagnosed with a novel RuV-associated granulomatous dermatitis. CONCLUSIONS AND RELEVANCE: The findings of this study suggest that clinicians and pathologists may consider RuV-associated granulomatous dermatitis during evaluation of a patient because it might have implications for the diagnosis of cutaneous sarcoidosis, with RuV serving as a potential antigenic trigger, and for the diagnosis of granulomatous cutaneous T-cell lymphoma, with histopathologic features that may prompt an evaluation for immunodeficiency and/or RuV.

Brentuximab Vedotin for Relapsed or Refractory Sézary Syndrome.

Importance: Treatment options for Sézary syndrome (SS) are limited and associated with low response rates. Brentuximab vedotin is a CD30-directed antibody-drug conjugate approved for refractory CD30-positive cutaneous T-cell lymphoma. However, limited data exist on its efficacy in SS, including in the pivotal phase 3 ALCANZA (A Phase 3 Trial of Brentuximab Vedotin (SGN-35) Versus Physician's Choice [Methotrexate or Bexarotene] in Participants With CD30-Positive Cutaneous T-Cell Lymphoma) trial. Objective: To assess the preliminary efficacy and tolerability of brentuximab vedotin for SS. Design, Setting, and Participants: From January 1, 2017, to July 31, 2020, a total of 13 patients with SS received brentuximab vedotin and were analyzed as part of a retrospective case series. Median follow-up was 10.4 months (range, 1.4-34.6 months). All patients were 18 years or older with a diagnosis of SS and with B2 blood involvement at the time brentuximab vedotin therapy was initiated. This single-center study was conducted at a major academic referral center. Interventions: Intravenous brentuximab vedotin administration approximately every 3 weeks. Main Outcomes and Measures: The primary end point was the global response rate. Outcomes were assessed in the skin and lymph nodes per the 2011 European Organization for Research and Treatment of Cancer-International Society of Cutaneous Lymphoma response criteria and in the blood per the 2018 Prospective Cutaneous Lymphoma International Prognostic Index revised blood response criteria. Results: The study included 13 patients (8 [62%] male; mean [SD] age, 68.2 [8.6] years). Of these 13 patients, 5 (38%) achieved a global response after a median of 6 cycles, including 1 complete response. Response rates by disease compartment were 38% in the skin, 63% in the blood, and 50% in the lymph nodes. Three of 11 patients (27%) with pruritus reported improvement. Skin CD30 positivity (>10%) was detected in 9 patients but was not associated with responses. Among responders, the median time to response was 6 weeks (range, 6-9 weeks), and the median duration of response was 5.5 months (range, 2.5-28.9 months). The median time to next treatment was 3.2 months (range, 1.5-36.7 months). Peripheral neuropathy occurred in 4 patients but resolved in 2 patients. Grade 2 adverse events were neuropathy (n = 2), constipation (n = 1), and hand-foot syndrome (n = 1). Conclusions and Relevance: In this case series, brentuximab vedotin use was associated with some efficacy in SS across multiple disease compartments and in the setting of refractory disease or low CD30 skin expression. Brentuximab vedotin may offer a manageable treatment schedule and low incidence of significant toxic effects.

Low-Dose Total Skin Electron Beam Therapy as Part of a Multimodality Regimen for Treatment of Sézary Syndrome: Clinical, Immunologic, and Molecular Analysis.

Importance: Sézary syndrome (SS) is an advanced form of cutaneous T-cell lymphoma with few long-term remissions observed. Objective: To profile 3 patients with SS who have experienced long-term remission following the addition of low-dose total skin electron beam therapy (TSEBT) to systemic regimens of extracorporeal photopheresis, bexarotene, and interferon-γ. Design, Setting, and Participants: This is a retrospective case series with additional investigations of patient-donated samples to assess therapeutic response. The study was conducted at the University of Pennsylvania Cutaneous Lymphoma Clinic and follows 3 patients with stage IVA1 CD4+ SS who presented to the clinic between November 1, 2009, and November 1, 2017, and who had a history of SS that was refractory to multimodality systemic therapy prior to receiving low-dose TSEBT. Interventions: Patients were treated in a multimodality fashion with combined extracorporeal photopheresis, bexarotene, interferon-γ, and low-dose TSEBT. Main Outcomes and Measures: To characterize treatment responses in these patients, the extent of skin disease was measured with the modified severity weighted assessment tool. Blood disease was measured with flow cytometric assessments of Sézary cell count, CD4:CD8 ratio, and high throughput sequencing of the T-cell receptors. To assess for restoration of immune function, we measured markers of immune exhaustion, including PD-1 (programmed cell death 1), TIGIT (T-cell immunoreceptor with immunoglobulin and ITIM domains), CTLA4 (cytotoxic T-lymphocyte-associated protein 4), TOX (thymocyte selection-associated high mobility group box protein), and Foxp3 (forkhead box P3) on circulating CD4 and CD8 T cells, along with production capacity of interferon-γ by lymphocytes following activation stimuli. Results: Following administration of low-dose TSEBT and maintenance of the other therapies, remissions ranged from 24 to 30 months, with complete responses in 2 patients ongoing. Markers of immune exhaustion including PD-1, TIGIT, CTLA4, TOX, and Foxp3 were significantly reduced from baseline following TSEBT, along with enhanced production capacity of interferon-γ by lymphocytes following activation stimuli. High throughput sequencing demonstrated near-complete eradication of the circulating clone among 2 of 3 patients with stable levels in 1. Conclusions and Relevance: We describe 3 patients who achieved long-term clinical and molecular remissions following low-dose TSEBT as part of a multimodality regimen for treatment of SS. As long-term remissions in SS are uncommon, this approach demonstrates promise, and clinical trials should be considered.

Striving for balance: A review of female dermatologists' perspective on managing a dual-career household.

As the gender gap in medicine continues to close, female dermatologists are striving to balance the competing demands of career ambitions and family responsibilities. Despite gaining a new sense of autonomy and personal fulfillment, working women report feelings of guilt, frustration, and exhaustion as they struggle to be a good doctor, partner, mother, family member, and friend. The presence of children in the household and the asymmetrical division of labor have been reported as main stressors for women in dual-career families. Finding time for self-care and maintaining a robust support system are effective strategies to mitigate these challenges. In this study, we performed a literature review to evaluate the internal and external pressures among working women in dual-career families. In addition, we provide the personal commentary of Sara Samimi and Karolyn A. Wanat, two female dermatologists living in dual-career families, to gain further insight into the difficulties of balancing personal and professional responsibilities.
