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.

Objectives: Some of the nation's 26 million veterans have two government-financed health care entitlements: Medicare and the Department of Veterans Affairs (VA). The aims of this investigation were to examine trends where Medicare-eligible VA users are initially hospitalized for acute myocardial infarction (AMI) and then to assess rates of cardiac procedure use and mortality for veterans initially admitted to each system of care., Methods: We used VA and HCFA national databases to identify VA users (age range, > or = 65 years) who were initially admitted to a VAMC or Medicare financed hospital (Medicare hospital) with a primary diagnosis of AMI between January 1, 1992, and December 31, 1995, (n = 47,598). We examined the use of cardiac procedures (cardiac catheterization [CC], coronary artery bypass surgery [CABG], and coronary angioplasty [CA] and mortality (30-day and 1-year) by the type of initial admitting hospital within each system of care., Results: Almost 70% of VA users hospitalized for AMI were initially admitted to Medicare hospitals versus VAMCs between 1992 (64%) and 1995 (72%). After adjusting for patient characteristics in logistic models, VA users initially hospitalized in Medicare hospitals were significantly more likely to undergo cardiac procedures than were VA users hospitalized in VAMCs. Differences in the odds of receiving a procedure were most significant when comparing Medicare hospitals with on-site cardiac technology to VA hospitals without on-site cardiac technology (CC: OR 4.34, 95% CI 3.98-4.73; CABG: OR 2.16, 95% CI 1.92-2.43; CA: OR 4.56, 95% CI 3.98-5.25). We found no significant differences in 30-day and 1-year adjusted mortality rates between VA users initially admitted to VAMCs or Medicare hospitals., Conclusions: Medicare-eligible VA users are increasingly hospitalized in Medicare hospitals for AMI. VA users cared for in Medicare hospitals receive more cardiac procedures but have the same survival as VA users cared for in VAMCs. These findings have policy implications for access, quality, and costs in both systems of care.
