RESUMO

BACKGROUND: Innovative technology can enhance patient access to healthcare but must be successfully implemented to be effective. OBJECTIVE: We evaluated Department of Veterans Affairs' (VA's) implementation of My VA Images, a direct-to-patient asynchronous teledermatology mobile application enabling established dermatology patients to receive follow-up care remotely instead of in-person. DESIGN /PARTICIPANTS/APPROACH: Following pilot testing at 3 facilities, the app was introduced to 28 facilities (4 groups of 7) every 3 months using a stepped-wedge cluster-randomized design. Using the Organizational Theory of Implementation Effectiveness, we examined the app's implementation using qualitative and quantitative data consisting of encounter data from VA's corporate data warehouse; app usage from VA's Mobile Health database; bi-monthly reports from facility representatives; phone interviews with clinicians; and documented communications between the operational partner and facility staff. KEY RESULTS: Implementation policies and practices included VA's vision to expand home telehealth and marketing/communication strategies. The COVID-19 pandemic dominated the implementation climate by stressing staffing, introducing competing demands, and influencing stakeholder attitudes to the app, including its fit to their values. These factors were associated with mixed implementation effectiveness, defined as high quality consistent use. Nineteen of 31 exposed facilities prepared to use the app; 10 facilities used it for actual patient care, 7 as originally intended. Residents, nurse practitioners, and physician assistants were more likely than attendings to use the app. Facilities exposed to the app pre-pandemic were more likely to use and sustain the new process. CONCLUSIONS: Considerable heterogeneity existed in implementing mobile teledermatology, despite VA's common mission, integrated healthcare system, and stakeholders' broad interest. Identifying opportunities to target favorable facilities and user groups (such as teaching facilities and physician extenders, respectively) while addressing internal implementation barriers including incomplete integration with the electronic health record as well as inadequate staffing may help optimize the initial impact of direct-to-patient telehealth. The COVID pandemic was a notable extrinsic barrier. CLINICAL TRIALS REGISTRATION: NCT03241589.

RESUMO

Purpose: To improve patient access to skin care, the Department of Veterans Affairs (VA) developed a patient-facing asynchronous mobile teledermatology application (app), which allows patients to follow up remotely with dermatologists. To understand how the app would be received in VA, we examined Organizational Readiness for Change (ORC), an important prelude to effective implementation, which includes the shared resolve and collective ability of organizational members to implement a change. Methods: We used a mixed-methods multiple case study approach to assess ORC at three VA facilities. Data derived from a site process call, surveys, and semistructured telephone interviews of VA staff, field notes, and administrative data. Results: Participants at all three facilities supported the intervention and recognized the value of using the app to increase patients' access to dermatologists, but expressed concerns largely related to disruption of the pre-existing clinical workflow. Participants at the facility most actively using the app had the highest overall ORC score and reported the most facilitators. Facility leadership support when guided by a clinical champion minimized barriers by recognizing the complexities of health care provision at specialty clinics. Discussion: While provider buy-in remained a barrier, leadership, guided by the clinical champion, played a critical role instituting implementation strategies. The strong association between the ORC survey score and the presence of facilitators and barriers suggests that the ORC survey may be a rapid, convenient, and effective tool for health care systems to identify favorable sites for wider implementation of mobile telehealth care. Clinical Trials Identifier: NCT03241589.

RESUMO

BACKGROUND: The risk of skin cancer associated with antihypertensive medication use is unclear, although thiazides have been implicated in regulatory safety warnings. We aimed to assess whether use of thiazides and other antihypertensives is associated with increased rates of keratinocyte carcinoma and melanoma. METHODS: We conducted a population-based inception cohort study using linked administrative health data from Ontario, 1998-2017. We matched adults aged ≥ 66 years with a first prescription for an antihypertensive medication (thiazides, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, calcium channel blockers, ß-blockers) by age and sex to 2 unexposed adults who were prescribed a non-antihypertensive medication within 30 days of the index date. We evaluated each antihypertensive class in a separate cohort study. Our primary exposure was the cumulative dose within each class, standardized according to the World Health Organization's Defined Daily Dose. Outcomes were time to first keratinocyte carcinoma, advanced keratinocyte carcinoma and melanoma. RESULTS: The inception cohorts included a total of 302 634 adults prescribed an antihypertensive medication and 605 268 unexposed adults. Increasing thiazide exposure was associated with an increased rate of incident keratinocyte carcinoma (adjusted hazard ratios [HRs] per 1 Defined Annual Dose unit 1.08, 95% confidence interval [CI] 1.03-1.14), advanced keratinocyte carcinoma (adjusted HR 1.07, 95% CI 0.93-1.23) and melanoma (adjusted HR 1.34, 95% CI 1.01-1.78). We found no consistent evidence of association between other antihypertensive classes and keratinocyte carcinoma or melanoma. INTERPRETATION: Higher cumulative exposure to thiazides was associated with increased rates of incident skin cancer in people aged 66 years and older. Consideration of other antihypertensive treatments in patients at high risk of skin cancer may be warranted.

RESUMO

Introduction: Few systematic evaluations of implementing teledermatology programs in large health care systems exist. We conducted a longitudinal evaluation of a U.S. Department of Veterans Affairs (VA) initiative to expand asynchronous consultative teledermatology services for rural veterans. Methods: The reach, effectiveness, adoption, implementation, and maintenance framework guided the evaluation, which included analysis of quantitative VA administrative data as well as an online survey completed by participating facilities. The first 2 years of the program were compared with the year before the start of funding. Results: Sixteen hub facilities expanded teledermatology's reach over the 2-year period, increasing the number of referral spoke sites, unique patients served, and teledermatology encounters. Effectiveness was reflected as teledermatology constituted an increasing fraction of dermatology activity and served more remotely located patients. Adoption through defined stages of implementation progressed as facilities engaged in a variety of strategies to enhance teledermatology implementation, and facilitators and barriers were identified. Program maintenance was assessed by Program Sustainability Index scores, which reflected the importance of executive support, and ongoing concerns about staffing and longitudinal funding. Discussion: Enabling hubs to create solutions that best fit their needs and culture likely increased reach and effectiveness. Important facilitators included organizational leadership and encouraging communication between stakeholders before and during the intervention. Conclusions: A systematic analysis of teledermatology implementation to serve rural sites in VA documented a high degree of implementation and sustainability as well as areas for improvement.

RESUMO

Background: While teledermatology is well-established in the Department of Veterans Affairs (VA), its implementation is far from complete. To facilitate consultative teledermatology and extend its reach, VA introduced a mobile teledermatology application (app) at three VA sites. Methods: We evaluated the initial implementation process using a mixed-methods, multiple case study approach to assess organizational readiness for change (ORC), which included examining facilitators, barriers, and contextual factors that affected implementation. We conducted: (1) group interviews and bimonthly reports to understand site processes; (2) semistructured interviews and surveys of individual participants representing a range of implementation roles; and (3) a review of internal organizational documents. We identified themes from interviews using an iterative process, and computed an ORC score based on surveys. Results: Forty-three individuals participated in the study. Qualitative data from all sites, corroborated by survey data available from one site, revealed a high readiness for change with an ORC score of 4.2, where 5 = maximal readiness for change. Facilitators included support from leadership and clinical champions, active telehealth programs, and an understanding and appreciation of the program and the resources needed. At all sites, however, technical issues negatively affected adoption; these included a suboptimal information technology infrastructure, which led to the inoperability of the app at two sites, and technical inefficiencies related to users' unfamiliarity with new devices and inconsistent internet access. Conclusions: Although a strong commitment to change and a confidence to effect change existed, these alone were insufficient to surmount barriers to implementation effectiveness. Clinical Trials Registration: NCT03241589.

RESUMO

BACKGROUND: Although treatment guidelines exist for melanoma in situ and invasive melanoma, guidelines for other melanocytic skin lesions do not exist. OBJECTIVE: To examine pathologists' treatment suggestions for a broad spectrum of melanocytic skin lesions and compare them with existing guidelines. METHODS: Pathologists (N = 187) completed a survey and then provided diagnoses and treatment suggestions for 240 melanocytic skin lesions. Physician characteristics associated with treatment suggestions were evaluated with multivariable modeling. RESULTS: Treatment suggestions were concordant with National Comprehensive Cancer Network guidelines for the majority of cases interpreted as melanoma in situ (73%) and invasive melanoma (86%). Greater variability of treatment suggestions was seen for other lesion types without existing treatment guidelines. Characteristics associated with provision of treatment suggestions discordant with National Comprehensive Cancer Network guidelines were low caseloads (invasive melanoma), lack of fellowship training or board certification (melanoma in situ), and more than 10 years of experience (invasive melanoma and melanoma in situ). LIMITATIONS: Pathologists could not perform immunohistochemical staining or other diagnostic tests; only 1 glass side was provided per biopsy case. CONCLUSIONS: Pathologists' treatment suggestions vary significantly for melanocytic lesions, with lower variability for lesion types with national guidelines. Results suggest the need for standardization of treatment guidelines for all melanocytic lesion types.

RESUMO

Keratinocyte carcinoma (KC) is the most common malignancy in white skinned populations. Metformin one of the most commonly prescribed drugs and has been reported to protect against solid cancers. The association between metformin and KC has not been studied in patients at high risk for a subsequent KC. The purpose of this study is to evaluate the association between metformin and KC development in high-risk patients. We performed a secondary analysis of patients enrolled in the Veterans Affairs Keratinocyte Carcinoma Chemoprevention Trial to compare risk for KC development between metformin users and non-users. Metformin-users compared to non-users had a significantly lower risk for squamous cell carcinoma with an adjusted Hazard ratio (HR): 0.45, (CI: 0.24-0.84, P < .01) and basal cell carcinoma (HR: 0.70, CI: 0.49-0.97, P < .03). Patients at high risk might benefit from metformin use against a subsequent KC.

RESUMO

BACKROUND: Keratinocyte carcinoma (KC) mortality is relatively modest and its measures are subject to considerable error. Deaths due to KC have been decreasing through 2000 and were relatively stable until 2010. OBJECTIVE: To estimate the KC mortality rates (MRs) from 2011 to 2017 in USA based on death certificates. METHODS: A population-based analysis of Center of Disease Control and Prevention data. Main outcomes and measures were the age-adjusted (US 2000 standard population) MRs. RESULTS: Overall, KC MRs increased significantly (b = 0.04, p < .01). For the period studied, KC MR was 1.24 per 100,000 persons per year (0.62 for sun-exposed sites, 0.38 for genital and 0.23 for perianal sites). At sun-exposed genital and perianal anatomic sites, KC MRs have been increasing in whites, but not in blacks. CONCLUSION: There was a 17% decrease in the KC MRs until 2000, followed by an increase of 44% through 2017. The accuracy of KC MRs is uncertain. If indeed the increase in mortality is verified, causes may include an increase in KC incidence, an increase of immunosuppressed populations, and changes in the cause of death documentation.

RESUMO

Recent progress in the treatment of advanced melanoma has led to unprecedented improvements in overall survival and, as these new melanoma treatments have been developed and deployed in the clinic, much has been learned about the natural history of the disease. Now is the time to apply that knowledge toward the design and clinical evaluation of new chemoprevention agents. Melanoma chemoprevention has the potential to reduce dramatically both the morbidity and the high costs associated with treating patients who have metastatic disease. In this work, scientific and clinical melanoma experts from the national Melanoma Prevention Working Group, composed of National Cancer Trials Network investigators, discuss research aimed at discovering and developing (or repurposing) drugs and natural products for the prevention of melanoma and propose an updated pipeline for translating the most promising agents into the clinic. The mechanism of action, preclinical data, epidemiological evidence, and results from available clinical trials are discussed for each class of compounds. Selected keratinocyte carcinoma chemoprevention studies also are considered, and a rationale for their inclusion is presented. These data are summarized in a table that lists the type and level of evidence available for each class of agents. Also included in the discussion is an assessment of additional research necessary and the likelihood that a given compound may be a suitable candidate for a phase 3 clinical trial within the next 5 years.
