Administrative Burden and Costs of Prior Authorizations in a Dermatology Department.

Importance: Insurance companies use prior authorizations (PAs) to address inappropriate prescribing or unnecessary variations in care, most often for expensive medications. Prior authorizations negatively affect patient care and add costs and administrative burden to dermatology offices. Objective: To quantify the administrative burden and costs of dermatology PAs. Design, Setting, and Participants: The University of Utah Department of Dermatology employs 2 full-time and 8 part-time PA staff. In this cross-sectional study at a large academic department spanning 11 clinical locations, these staff itemized all PA-related encounters over a 30-day period in September 2016. Staff salary and benefits were publicly available. Data were analyzed between December 2018 and August 2019. Main Outcomes and Measures: Proportion of visits requiring PAs, median administrative time to finalize a PA (either approval or denial after appeal), and median cost per PA type. Results: In September 2016, 626 PAs were generated from 9512 patient encounters. Staff spent 169.7 hours directly handling PAs, costing a median of $6.72 per PA. Biologic PAs cost a median of $15.80 each and took as long as 31 business days to complete. The costliest PA equaled 106% of the associated visit's Medicare reimbursement rate. Approval rates were 99.6% for procedures, 78.9% for biologics, and 58.2% for other medications. After appeal, 5 of 23 (21.7%) previously denied PAs were subsequently approved. Conclusions and Relevance: Prior authorizations are costly to dermatology practices and their value appears limited for some requests. Fewer unnecessary PAs and appeals might increase practice efficiency and improve patient outcomes.

Process of Post-operative Telephone Follow-up Implementation for Mohs Micrographic Surgery: A Pilot Study.

Objective: The purpose of this study was to describe and evaluate the process of implementing a routine telephone follow-up (TFU) system for capturing postoperative complications or concerns among Mohs micrographic surgery (MMS) patients. Design: Postoperatively, patients were called twice: 1) within 24 to 48 hours to assess bleeding, swelling, and pain control; and 2) at one week to assess wound care, signs of infection, or other concerns. Setting: The study took place in a single-institution academic dermatology department with five fellowship-trained Mohs surgeons. Participants: Study subjects included patients undergoing MMS during a two-month period. Measurements: Data regarding completed TFU rate, time to complete calls, and patient-reported complication rates were collected and analyzed. Results: Of 349 MMS patients, 263 (75.4%) were successfully contacted during the 24- to 48-hour follow-up window and 232 (66.5%) at the one week interval. Major complication rates were 0.4 percent (n=1) for bleeding and 0.4 percent (n=1) for infection; both were treated by their respective Mohs surgeon. Timed calls averaged approximately three minutes per encounter. Conclusion: TFU is practical and efficient for assessing and mitigating MMS postoperative complications.

How to reduce out-of-pocket costs for prescription medications.

The cost of prescription medicines has recently been rising faster than other healthcare costs.  This is also true for traditionally inexpensive generic medications that have long served as a fundamental healthcare safety net in the USA.  These changes increasingly present challenges for individuals to obtain common medications.  Owing to rising insurance co-pays, even patients who have prescription medication insurance coverage are beginning to experience challenges in this area.  This document was created to help patients and their families consider various strategies and programs that exist in 2015 for reducing their out-of-pocket costs for their prescription medications.  We believe that this information can also be helpful to healthcare providers when counseling patients about managing rapidly rising prescription drug costs.  An effort has been made to make this document readable to patients and their families as well as to healthcare providers.

Dermatological medication effects on male fertility.

Many drugs have been reported to impair semen parameters, leading to temporary or persistent infertility. Therefore, potential fathers may be concerned about the effect of medications on fertility. We searched the MEDLINE database of articles in English combining key terms including "male infertility," "spermatogenesis," "fertility," "drug effects," and "dermatology." Administration of methotrexate and finasteride has resulted in severe oligospermia and reversible infertility. Ketoconazole has had negative effects on sperm motility and testosterone production. Few individual case reports and a limited number of studies have demonstrated negative effects of tetracyclines, erythromycin, chloroquine, glucocorticoids, spironolactone, and antihistamines on fertility. It is important to counsel male patients when appropriate about the reversible negative effect on fertility when taking methotrexate and finasteride, and the adverse effect of ketoconazole. Patients may be reassured that taking oral retinoids, cyclosporine, azathioprine, and tumor necrosis factor alpha inhibitors should not affect their fertility.

A review of the clinical phenotype of 254 patients with genetically confirmed pachyonychia congenita.

BACKGROUND: Pachyonychia congenita (PC) is a group of autosomal dominant keratinizing disorders caused by a mutation in one of 4 keratin genes. Previous classification schemes have relied on data from case series and case reports. Most patients in these reports were not genetically tested for PC. OBJECTIVE: We sought to clarify the prevalence of clinical features associated with PC. METHODS: We surveyed 254 individuals with confirmed keratin mutations regarding their experience with clinical findings associated with PC. Statistical comparison of the groups by keratin mutation was performed using logistic regression analysis. RESULTS: Although the onset of clinical symptoms varied considerably among our patients, a diagnostic triad of toenail thickening, plantar keratoderma, and plantar pain was reported by 97% of patients with PC by age 10 years. Plantar pain had the most profound impact on quality of life. Other clinical findings reported by our patients included fingernail dystrophy, oral leukokeratosis, palmar keratoderma, follicular hyperkeratosis, hyperhidrosis, cysts, hoarseness, and natal teeth. We observed a higher likelihood of oral leukokeratosis in individuals harboring KRT6A mutations, and a strong association of natal teeth and cysts in carriers of a KRT17 mutation. Most keratin subgroups expressed a mixed constellation of findings historically reported as PC-1 and PC-2. LIMITATIONS: Data were obtained through questionnaires, not by direct examination. Patients were self- or physician-referred. CONCLUSIONS: We propose a new classification for PC based on the specific keratin gene affected to help clinicians improve their diagnostic and prognostic accuracy, correct spurious associations, and improve therapeutic development.

Treatment of chronic urticaria with colchicine.

BACKGROUND: Chronic urticaria (CU) is a cutaneous disease that can be debilitating, difficult to treat, and sometimes life-threatening. Treatment with antihistamines is often ineffective. Immunosuppressants are second line therapy but can have significant side effects. Data is needed on effective therapies with safer profiles. OBJECTIVES: To determine the efficacy and side-effects of colchicine in patients with CU. METHODS: Patients were identified through retrospective chart reviews at the University of Utah from 2002-2007. We identified 36 patients with a diagnosis of chronic urticaria based on history, physical examination, and a skin biopsy. Length of treatment ranged from one month to 17 months. RESULTS: Subjective clinical responses to colchicine therapy reported as complete (n=15) or partial (n=5) were found in 56 percent of patients. The mean±SD duration of treatment was 7±6 months. Three patients (15%) who had resolution of urticaria stopped colchicine secondary to diarrhea and hematuria. Of the complete responders, nine individuals (60%) have remained symptom free and four individuals (27%) had recurrence after colchicine was stopped. LIMITATIONS: Short-term follow-up and retrospective study design. CONCLUSIONS: This retrospective study demonstrated that colchicine was an effective and well-tolerated treatment for patients unresponsive to antihistamines. The data supports the use of colchicine for CU patients and further controlled studies are warranted to better characterize the use of colchicine in patients with CU refractory to antihistamines.

Paternal germ cell mosaicism in autosomal dominant pachyonychia congenita.

BACKGROUND: Pachyonychia congenita (PC) is a genodermatosis caused by mutations in 1 of 4 known keratin genes, including KRT6A, KRT6B, KRT16, or KRT17. The most common mode of inheritance is autosomal dominant. Families with an affected parent are routinely counseled about the 50% transmission risk to each offspring. In some cases, families with a rare disorder like PC can initially present with an affected child while both parents are unaffected. This is usually the result of a spontaneous in utero mutation, and the risk of subsequent offspring being affected with the same condition is negligible (but may be increased above the general population's risk, although the exact risk is not currently known for PC). OBSERVATIONS: We discuss a case of 2 affected children born to unaffected parents. We performed mutational analyses of all 4 individuals in the family on DNA extracted from lymphocytes. Owing to the unusual presentation of 2 affected siblings, we also extracted DNA from the father's sperm cells for keratin gene mutational analysis. We describe the first case, to our knowledge, of germ cell mosaicism in PC. CONCLUSION: Counseling of unaffected parents with a first child diagnosed as having PC should entail a discussion of the possibility of germ cell mosaicism contributing to an increased risk of having subsequent affected children.

The phenotypic and molecular genetic features of pachyonychia congenita.

Pachyonychia congenita (PC) is an autosomal dominant genodermatosis caused by heterozygous mutations in any one of the genes encoding the differentiation-specific keratins K6a, K6b, K16, or K17. The main clinical features of the condition include painful and highly debilitating plantar keratoderma, hypertrophic nail dystrophy, oral leukokeratosis, and a variety of epidermal cysts. Although the condition has previously been subdivided into PC-1 and PC-2 subtypes, the phenotypic characterization of 1,000 mutation-verified PC patients enrolled in the International PC Research Registry, coordinated by the patient advocacy group PC Project, shows that there is considerable overlap between these subtypes. Thus, a new genotypic nomenclature is proposed, in which PC-6a represents a patient carrying a mutation in the K6a gene, etc. Although a rare disorder, PC represents a good model for therapy development, and international efforts are ongoing to develop and deliver siRNA, gene, correction, small molecule, and other strategies to treat this painful, disabling skin condition. The special relationship between PC Project and the PC research community has greatly accelerated the development pathway from gene identification to clinical trials in only a few years and represents a paradigm of hope for other orphan diseases.

First-in-human mutation-targeted siRNA phase Ib trial of an inherited skin disorder.

The rare skin disorder pachyonychia congenita (PC) is an autosomal dominant syndrome that includes a disabling plantar keratoderma for which no satisfactory treatment is currently available. We have completed a phase Ib clinical trial for treatment of PC utilizing the first short-interfering RNA (siRNA)-based therapeutic for skin. This siRNA, called TD101, specifically and potently targets the keratin 6a (K6a) N171K mutant mRNA without affecting wild-type K6a mRNA. The safety and efficacy of TD101 was tested in a single-patient 17-week, prospective, double-blind, split-body, vehicle-controlled, dose-escalation trial. Randomly assigned solutions of TD101 or vehicle control were injected in symmetric plantar calluses on opposite feet. No adverse events occurred during the trial or in the 3-month washout period. Subjective patient assessment and physician clinical efficacy measures revealed regression of callus on the siRNA-treated, but not on the vehicle-treated foot. This trial represents the first time that siRNA has been used in a clinical setting to target a mutant gene or a genetic disorder, and the first use of siRNA in human skin. The callus regression seen on the patient's siRNA-treated foot appears sufficiently promising to warrant additional studies of siRNA in this and other dominant-negative skin diseases.

Multiple primary melanomas in a CDKN2A mutation carrier exposed to ionizing radiation.

BACKGROUND: Recent research has shown a possible causal relationship between ionizing radiation exposure and melanoma. Individuals with mutations in CDKN2A (cyclin-dependent kinase inhibitor 2A), the major melanoma predisposition gene, have an increased susceptibility to melanoma-promoting exposures, such as UV light. We describe a patient from a familial melanoma pedigree with 7 primary melanomas on the right side of her body, the first occurring 5 years after exposure to atmospheric nuclear bomb testing in the 1950s. OBSERVATIONS: Physical examination revealed phototype I skin, red hair, and 26 nevi (14 on the right and 12 on the left side of her body). One nevus was larger than 5 mm, and 2 were clinically atypical. Sequence analysis demonstrated a known deleterious mutation in CDKN2A (G-34T) and homozygosity for a red hair color variant in MC1R (melanocortin 1 receptor) (R151C). Fluorescence in situ hybridization analysis of blood, fibroblasts, and melanocytes from both upper extremities ruled out mosaicism. CONCLUSIONS: Individuals such as this patient, who has CDKN2A and MC1R mutations, are likely to be more susceptible to environmental insults. A careful review of environmental exposures in these vulnerable cases may reveal cancer-promoting agents, such as ionizing radiation, that go unnoticed in less susceptible populations.

Management of melanoma during pregnancy.

There is no conclusive evidence that pregnancy adversely affects overall survival in patients with melanoma. Clinicians caring for pregnant patients should be as suspicious of changes in melanocytic nevi in these patients as they are for nonpregnant patients. Treatment of early-stage melanoma is the same irrespective of whether or not the patient is pregnant. Chemotherapeutic regimens for metastatic disease administered during pregnancy have not demonstrated significant efficacy.

Population-based assessment of non-melanoma cancer risk in relatives of cutaneous melanoma probands.

Using the unique Utah Population Database, which links Utah genealogical data with Utah cancer data, we examined risks for other cancers among relatives of 4,079 melanoma cases. Age- and sex-specific rates for 35 different cancer sites were calculated, and used to estimate relative risks among relatives. In addition to the well-recognized risk for melanoma among first-degree relatives, we found significantly increased risks for prostate, breast, and colon cancers, non-Hodgkin's lymphoma, and multiple myeloma, ranging from 32 to 72% increased risk. Among second-degree relatives, in addition to increased risk for melanoma, we identified significantly increased risks for prostate cancer and multiple myeloma (27 and 53% increase, respectively). Among first-degree relatives of melanoma cases diagnosed before the age of 40 years, we found significantly elevated risks for cutaneous melanoma (380% increase) and prostate cancer (83% increase). Significantly increased risks for prostate cancer and multiple myeloma in both first- and second-degree relatives of melanoma cases are suggestive of heritable cancer syndromes. The increased risks for five additional cancer types in first-degree relatives of melanoma cases suggest that individuals with a family history of melanoma should strictly adhere to recommended screenings for all cancers.

Population-based prevalence of CDKN2A mutations in Utah melanoma families.

Cyclin-dependent kinase inhibitor 2A (CDKN2A or p16) is the major melanoma predisposition gene. In order to evaluate the candidacy for genetic testing of CDKN2A mutations among melanoma prone families, it is important to identify characteristics that predict a high likelihood of carrying a CDKN2A mutation. We primarily used a unique Utah genealogical resource to identify independent melanoma prone families whom we tested for mutations in CDKN2A, cyclin-dependent kinase 4, and alternate reading frame. We sampled 60 families which met the inclusion criteria of two or more affected first-degree relatives. We found four different pathogenic CDKN2A mutations in five families, mutations of uncertain significance in two families, and known polymorphisms in three families. One of the mutations of uncertain significance, 5' untranslated region -25C>T, has not been previously described. Among our population-based set of Utah families, the prevalence of CDKN2A mutations was 8.2% (4/49); the overall prevalence when physician-referred pedigrees were also considered was between 8.3% (5/60) and 10% (6/60). Having four or more first- or second-degree relatives with melanoma, or a family member with > or =3 primary melanomas, correlated strongly with carrying a CDKN2A mutation. We observed a significantly elevated rate of pancreatic cancer in one of four families with a deleterious CDKN2A mutation.
