Objective Outcome Measures for Trials in Patients With Chronic Limb-Threatening Ischemia Across 2 Decades: Analysis and Recommendations.

Chronic limb-threatening ischemia (CLTI) is prevalent and associated with morbidity and mortality. The published research concerning CLTI therapeutics is evolving. The goals of this review are to: 1) summarize the endpoints that are being used in trials assessing interventions for patients with CLTI; and 2) review gaps and discrepancies in current outcome definitions. A search was conducted of the PubMed database and ClinicalTrials.gov to identify studies published between January 2000 and March 2020 that evaluated treatment options for patients with CLTI. Meta-analyses, case series, case reports, abstracts, and expert opinion were excluded. Forty-nine studies (n = 11,667) were identified that fulfilled the inclusion criteria. Most trials reported clinical outcomes (mortality, 69.4%; limb events, 87.8%; target lesion revascularization, 83.7%). Mean follow-up duration was 23.7 months. In investigational device exemption trials, total follow-up and follow-up to primary outcomes were discordant (12 months vs 6 months; P = 0.0018). Hemodynamic testing was reported in 71.4%, usually ankle-brachial index. Patency was assessed in 89.8% of trials; ultrasound was used in 65.3% and invasive angiography in 85.7%, at baseline and/or during follow-up. Wound assessment was performed in 49.0% of studies, qualitative in 28.6% and quantitative in 20.4%. Finally, quality of life assessment was performed in 55% of studies. Definitions for many outcomes varied across studies. Consensus regarding which outcomes to study, uniform definitions, and optimal methods to measure some of these outcomes are yet to be established. A comprehensive effort by all stakeholders is needed to move the field of CLTI forward.

Evaluation of electronic consults for outpatient pediatric patients with dermatologic complaints.

BACKGROUND: Although dermatologic complaints are frequently encountered by pediatricians, access to pediatric dermatologists remains limited. Teledermatology has been proposed to expand access to dermatologic care for children. We report our experience with a physician-to-physician store-and-forward teledermatology service (eConsults), focusing on patient and consult characteristics and their relationship with teledermatologist confidence and follow-up recommendations as well as clinical outcomes. METHODS: We reviewed electronic health records of all pediatric patients referred through eConsults at the Massachusetts General Hospital from 1/13/2020 to 7/17/2020. We assessed pediatrician and parental receptiveness with a confidential survey. RESULTS: A total of 302 referrals (median patient age 4.6 years (IQR 0.6-12); 54% female) and 310 cases were completed in 1.8 days on average (SD = 1.2). Teledermatologists rated their confidence as definite and moderate in 51.3% and 39.4% cases, respectively. Teledermatologists felt comfortable managing rashes remotely, but patients with alopecia, pigmented and vascular lesions, and warts frequently required formal dermatology evaluation. Among patients seen subsequently, full concordance was seen for 70.1% of diagnoses and 74.4% of management recommendations. All responding pediatricians were satisfied with the service, and 97.5% felt that the parents were receptive to it. CONCLUSIONS: Our study supports the growing evidence that store-and-forward teledermatology can quickly and effectively provide the access to pediatric dermatologic care and is well received by pediatricians and parents. To maximize cost-effectiveness of store-and-forward teledermatology, dermatologists should work with referring providers to improve the quality of submitted photographs and patient history as well as advise in-person referrals for cases likely to require further follow-up.

Disparities in telemedicine access for Spanish-speaking patients during the COVID-19 crisis.

The rapid rise of telemedicine during the COVID-19 pandemic raised the prospect of worsening health care disparities for vulnerable populations. We retrospectively compared pediatric teledermatology visits scheduled during the pandemic (03/17/2020-07/31/2020) with in-person appointments scheduled during the same period in 2019 and found that Spanish-speaking patients had significantly fewer scheduled appointments in 2020 (9% vs 5%, P < .001). Among the telemedicine cohort, Spanish-speaking patients were less likely to have an email address documented within the electronic medical record and less likely to have activated an online patient portal account prior to their visit during the pandemic (45% vs 62%, P = .017, and 23% vs 66%, P < .001, respectively). Our findings suggest that email connectedness may represent a bottleneck in telemedicine access for Spanish-speaking pediatric dermatology patients.

Pediatric dermatology eConsults: Reduced wait times and dermatology office visits.

BACKGROUND/OBJECTIVES: Store-and-forward teledermatology provides pediatricians with specialist guidance in managing skin disease. This study evaluates wait times and face-to-face (FTF) dermatology visit avoidance associated with a pediatric dermatology eConsult program at an urban academic medical center. METHODS: In this retrospective cohort study, electronic medical records were reviewed for patients under age 18 for whom a dermatology eConsult was completed between November 1, 2014, and December 31, 2017. Wait times for eConsult completion and initial FTF dermatology appointments were calculated and compared to average wait times for new patient dermatology office appointments from 2016 to 2017. Recommendations for FTF dermatology visits were assessed, along with FTF visit attendance and potential cost savings. RESULTS: One hundred eighty pediatric patients with 188 unrelated skin conditions ("cases") were referred to the program. Of 188 cases, FTF dermatology visits were recommended for 60 (31.9%). Actual FTF dermatology visit avoidance was 53.7% of total cases (n = 101 for whom FTF visit was not recommended and no dermatology visit occurred within 90 days after eConsult submission). The program generated potential savings of $24 059 ($9840 out-of-pocket) in 2016 dollars. Average turnaround for eConsult completion was 1.8 calendar days (median: 1 calendar day, target: 2 business days). Average wait time to initial FTF dermatology evaluation was 37.3 calendar days (versus 54.1 days for pediatric patients referred directly to dermatology clinic between 2016 and 2017). CONCLUSION: Pediatric dermatology eConsults reduce wait times for specialist care, triage cases for in-office evaluation, reduce need for FTF dermatology visits, and offer potential cost savings for payers and patients.

Alcohol-Associated Immunoglobulin A Vasculitis: A Case Report and Review of the Literature.

Immunoglobulin A (IgA)-mediated leukocytoclastic vasculitis is a cutaneous small-vessel vasculitis characterized by skin findings of palpable purpura. It may occur secondary to infections, neoplasms, drugs, and systemic conditions, although it is most commonly idiopathic. A known, but rare, trigger for IgA vasculitis is alcohol consumption. We present a case of a man with IgA vasculitis associated with alcohol use and review the literature on alcohol-associated vasculitis. Although rarely reported, alcohol-associated IgA vasculitis is an important entity to consider for appropriate diagnosis and management of such patients.

Factors Influencing Patient Decisions Regarding Treatments for Skin Growths: A Cross-Sectional Study.

Variations in treatment modalities for skin growths contribute substantially to overall healthcare spending within dermatology. However, little is known regarding factors impacting patient decision-making when choosing a treatment modality. In this survey-based, cross-sectional study (n = 375, 81.9% response rate), we asked patients to rate the importance of different treatment parameters for a nonfacial skin growth, further classified into five domains: efficacy, appearance, financial impact, visit duration, and productivity. Although patients generally prioritized treatment efficacy when selecting a treatment modality, they emphasized different aspects of the treatment experience as a function of age, gender, race, insurance status, and history of malignancy. Patients over age 50 were less likely to consider treatment impact on finances as being "important", but more so efficacy and visit duration. Women were more likely to value efficacy and appearance. Patients without private insurance were more likely to cite efficacy and impact on productivity as being "important". While the underlying reasons for these variations differ across patients, these findings help explain variations in treatment selection among patients choosing between treatments for skin growths and may ultimately lead to improved shared decision-making.

A 71-Year-Old Female with Myocardial Infarction and Long-Standing Ulcers on the Thigh.

Calciphylaxis is most commonly encountered in patients with end-stage renal disease; however, it is increasingly observed in nonuremic patients as well. It is important to consider and diagnose nonuremic calciphylaxis early, as prompt treatment and mitigation of associated risk factors is essential to improve long-term outcomes for these patients. Here, we present the case of a 71-year-old woman with atrial fibrillation on warfarin, but without renal disease, who presented with two long-standing ulcers on her thigh and was diagnosed with the aid of biopsy with calciphylaxis. We review the existing literature on the subject and offer this case as a representative report of a clinicopathologic correlation for this disorder.

Recent advances in acne pathogenesis: implications for therapy.

Acne pathogenesis is a multifactorial process that occurs at the level of the pilosebaceous unit. While acne was previously perceived as an infectious disease, recent data have clarified it as an inflammatory process in which Propionibacterium acnes and innate immunity play critical roles in propagating abnormal hyperkeratinization and inflammation. Alterations in sebum composition, and increased sensitivity to androgens, also play roles in the inflammatory process. A stepwise approach to acne management utilizes topical agents for mild to moderate acne (topical retinoid as mainstay ± topical antibiotics) and escalation to oral agents for more resistant cases (oral antibiotics or hormonal agents in conjunction with a topical retinoid or oral isotretinoin alone for severe acne). Concerns over antibiotic resistance and the safety issues associated with isotretinoin have prompted further research into alternative medications and devices for the treatment of acne. Radiofrequency, laser, and light treatments have demonstrated modest improvement for inflammatory acne (with blue-light photodynamic therapy being the only US FDA-approved treatment). However, limitations in study design and patient follow-up render these modalities as adjuncts rather than standalone options. This review will update readers on the latest advancements in our understanding of acne pathogenesis and treatment, with emphasis on emerging treatment options that can help improve patient outcomes.
