Retrospective review of insurance coverage for patch testing.

BACKGROUND: There is a paucity of data on the burden of insurance limitations for patients undergoing patch testing. OBJECTIVE: To characterize the burden of insurance limitations and its impact on differences in management and execution of patch testing. METHODS: A retrospective chart review was performed on patients with a diagnosis of contact dermatitis (International Classification of Disease [ICD], Ninth Edition, code ICD 692) who received patch testing (Current Procedural Terminology code 95044) at the George Washington Medical Faculty Associates Dermatology Clinic between January 1, 2015 and June 30, 2017. Variables including allergen limitations were compared between government-sponsored insurance and private insurance providers (eg, Insurers A, B, C, and D). RESULTS: A total of 371 records were identified. Government-sponsored insurance patients encountered allergen limitations more frequently than private insurance patients (86.8% vs 14.2%, P < .0001). Insurer C and D patients were least likely to encounter allergen limitations (1.2% vs 0%, P < .0001) and were tested to the most allergens (mean = 146 vs 152, P < .0001). Insurer A patients had the least allergens tested among those privately insured. CONCLUSION: Considering modification of insurance policies to allow patch testing with a larger number of allergens without restrictions is needed, with the goal of improving quality of life of these patients while saving costs from chronic use of topical corticosteroids.

Patient Awareness of Local Drug Price Variation and the Factors That Influence Pharmacy Choice: A Cross-sectional Survey Study

BACKGROUND: High out-of-pocket drug expenditures are increasingly common in dermatology. Patients may not be aware that prices vary among pharmacies and consequently may not shop for the lowest cost. OBJECTIVE: To determine what factors influence pharmacy choice and the effect of providing local prescription prices on pharmacy selection. We hypothesized that patients do not "shop around" due to lack of knowledge of price variation and would choose a pharmacy based on costs if educated on price disparity. METHODS: Between July and August 2016, we administered a cross-sectional anonymous survey to adults visiting four outpatient clinics at an academic tertiary care center in Washington, D.C. Participants answered questions before and after viewing a list of prescription drug prices from local pharmacies. RESULTS: 287 surveys were administered to a convenience sample of adults (age ≥ 18 and literate in English). Of the 287 participants, 218 fully completed the survey; 55.1% were women and 40.5% were over age 40. When considering a cost savings of $10-25, 65% would switch pharmacies if the distance were the same, and 21.3% would switch if the distance were 45-minutes further. After price education, fewer participants felt that drug price knowledge would ultimately influence pharmacy choice (P less than 0.0001). However, respondents' intended frequency of researching price online, calling a pharmacy to ask about price, and comparing price between pharmacies before filling a prescription all increased, compared to prior self-reported frequencies (P less than 0.001). Specifically, participants with $75,000-$99,999 income were more likely to compare prices than those with income below $45,000 (odds ratio [OR], 4.62; 95% confidence interval [CI], 1.24-17.28). CONCLUSION: In this study, pharmacy choice was more influenced by convenience than cost prior to drug price education. However, price education ultimately impacted intent to research prescription drug prices before selecting a pharmacy. Thus, knowledge of drug pricing may be useful in creating cost savings for patients.

Trends in dermatology practices and the implications for the workforce.

BACKGROUND: The American Academy of Dermatology (AAD) practice profile surveys have been conducted for more than a decade to gauge trends in our workforce supply and demand. OBJECTIVE: To update the trends and current workforce issues for the field of dermatology. METHODS: The AAD Practice Profile Survey is sent by both e-mail and postal mail to a random sample of practicing dermatologists who are AAD members. RESULTS: Shifts are noted in the primary practice setting; fewer dermatologists are in solo practice and more are in group practices than in previous years. Teledermatology use trended upward from 7% to 11% between 2012 and 2014. The implementation of electronic health records increased from 51% in 2011 to 70% in 2014. LIMITATIONS: There is potential for response bias and inaccurate self-reporting. Survey responses collected may not be representative of all geographic areas. CONCLUSION: The demand for dermatology services remains strong. Shifts in the practice setting may be related to increases in overhead costs that are partially associated with the implementation of technology-based medical records. Integration of electronic health records and utilization of telemedicine are increasing.

A Survey Assessment of US Dermatologists' Perception of Biosimilars.

BACKGROUND: Biologics have transformed the treatment of psoriasis and psoriatic arthritis, but at a significant cost to payers and patients. The introduction of biosimilars into the US market could reduce costs while increasing access to biologic medications.

OBJECTIVE: We sought to identify gaps in biosimilar knowledge and perception among US dermatologists.

METHODS: An online survey was sent to dermatologists from January to April 2015.

RESULTS: Ninety-seven US dermatologists responded, of which 84% state they prescribe biologics in their practice. Only 37% of dermatologists were aware that a biosimilar is highly similar to a US-licensed reference biological product, 26% incorrectly described a biosimilar as a "generic" of a known biologic, and 10% of dermatologists stated they did not know the definition. Most dermatologists (88%) believe that substitutions from biologics to biosimilars will be made by pharmacists without consulting the physician. A total of 37% of dermatologists believed that a biosimilar with the same name as a biologic suggested they are "structurally identical." Only 25% said they would likely prescribe biosimilars to their patients, while 38% stated they would try using them on a very select, small group of patients before trying it on a majority of their patients.

LIMITATIONS: Limitations include small sample size and non-responder bias.

CONCLUSION: A biosimilars knowledge gap exists amongst dermatologists, suggesting the need for more educational initiatives.

Insurance Coverage of Biologics for Moderate-to-Severe Psoriasis: A Retrospective, Observational 5-Year Chart Review.

BACKGROUND: With the variability in health insurance coverage for psoriasis systemic therapies, recent changes in coverage for biologics have yet to be evaluated. PURPOSE: To determine changes in insurance coverage of biologics for moderate-to-severe psoriasis between 2009 and 2014, with a focus on insurance policies as stated in prior authorization (PA) forms, coverage denials, and time course of approval process. METHODS: A retrospective chart review was performed on patients with a diagnosis of psoriasis (International Classification of Diseases [ICD], Ninth Edition, code ICD 696.1) seen at the Department of Dermatology, Medical Faculty Associates, George Washington University between January 1, 2009 and December 31, 2014. Exclusion criteria included <9 % body surface area, loss to follow-up, lack of biologic treatment, biologic treatment via a clinical trial, and lack of health insurance. For all other patients, metrics collected included age, sex, body surface area, health insurance plan, prior therapies, prescribed biologic, PA necessity, time in days between PA submission and coverage decision, and denial justifications. RESULTS: Eight hundred and sixty-four patients with a diagnosis of psoriasis within the time period were identified, 114 of who met the inclusion criteria. PA requirement increased from 16 % of patients prescribed a biologic in 2009 to 75 % of patients prescribed a biologic in 2014. The mean duration in days between PA submission and coverage decision from the insurance company increased from 3.7 days in 2009 to 6.7 days in 2014. PA denial rates increased from 0 % in 2009 to 19 % in 2014. The most common reason for coverage denial was failure to attempt alternative therapies prior to requesting biologics. CONCLUSION: Insurance coverage of biologics for moderate-to-severe plaque psoriasis has become increasingly regulated between 2009 and 2014. Given both the cost burden and potential benefits of these therapies, further examination of healthcare coverage and treatment accessibility is warranted for optimal patient outcomes.
