BackgroundAlthough the benefits of identifying and treating asymptomatic HIV-infected individuals are firmly established, health care
providers often miss opportunities to offer HIV-testing.

ObjectiveTo evaluate whether a multi-component intervention increases the rate of HIV diagnostic testing.

DesignPre- to post-quasi-experiment in 5 Veterans Health Administration facilities. Two facilities received the intervention; the
other three facilities were controls. The intervention included a real-time electronic clinical reminder that encourages HIV
testing, and feedback reports and a provider activation program.

PatientsPersons receiving health care between August 2004 and September 2006 who were at risk but had not been previously tested for
HIV infection

MeasurementsPre- to post-changes in the rates of HIV testing at the intervention and control facilities

ResultsAt the two intervention sites, the adjusted rate of testing increased from 4.8% to 10.8% and from 5.5% to 12.8% (both comparisons,
p < .001). In addition, there were 15 new diagnoses of HIV in the pre-intervention year (0.46% of all tests) versus 30 new
diagnoses in the post-intervention year (0.45% of all tests). No changes were observed at the control facilities.

ConclusionsUse of clinical reminders and provider feedback, activation, and social marketing increased the frequency of HIV testing and
the number of new HIV diagnoses. These findings support a multimodal approach toward achieving the Centers for Disease Control
and Prevention’s goal of having every American know their HIV status as a matter of routine clinical practice.

    • "We have successfully employed this succinct model to carry out implementation projects at more than 25 sites throughout the nationwide VA system, including several sites outside the VA (Anaya et al., 2012; Goetz et al., 2008; Knapp, Anaya, & Goetz, 2010; Anaya et al., under review). These implementations have largely been characterized by successful deployment and independent sustainability over time, streamlining healthcare delivery at these sites. "

    ABSTRACT: The process of quality improvement may involve enhancing or revising existing practices or the introduction of a novel element. Principles of Implementation Science provide key theories to guide these processes, however, such theories tend to be highly technical in nature and do not provide pragmatic nor streamlined approaches to real-world implementation. This paper presents a concisely comprehensive six step theory-based Implementation Science model that we have successfully used to launch more than two-dozen self-sustaining implementations. In addition, we provide an abbreviated case study in which we used our streamlined theoretical model to successfully guide the development and implementation of an HIV testing/linkage to care campaign in homeless shelter settings in Los Angeles County.

    ABSTRACT: BACKGROUNDSustainability—the routinization and institutionalization of processes that improve the quality of healthcare—is difficult to achieve and not often studied. OBJECTIVETo evaluate the sustainability of increased rates of HIV testing after implementation of a multi-component intervention in two Veterans Health Administration healthcare systems. DESIGNQuasi-experimental implementation study in which the effect of transferring responsibility to conduct the provider education component of the intervention from research to operational staff was assessed. PATIENTSPersons receiving healthcare between 2005 and 2006 (intervention year) and 2006 and 2007 (sustainability year). MEASUREMENTSMonthly HIV testing rate, stratified by frequency of clinic visits. RESULTSThe monthly adjusted testing rate increased from 2% at baseline to 6% at the end intervention year and then declined reaching 4% at the end of the sustainability year. However, the stratified, visit-specific testing rate for persons newly exposed to the intervention (i.e., having their first through third visits during the study period) increased throughout the intervention and sustainability years. Increases in the proportion of visits by patients who remained untested despite multiple, prior exposures to the intervention accounted for the aggregate attenuation of testing during the sustainability year. Overall, the percentage of patients who received an HIV test in the sustainability year was 11.6%, in the intervention year 11.1%, and in the pre-intervention year 5.0% CONCLUSIONSProvider education combined with informatics and organizational support had a sustainable effect on HIV testing rates. The effect was most pronounced during patients’ early contacts with the healthcare system.

    ABSTRACT: The formal mission and strategic goals of the Center for the Study of Healthcare Provider Behavior (see bottom of this page) guide our activities in the do- mains of research, dissemination, technical assis- tance and training. Our mission and activities are also guided by the strategic priorities and mission of the Veterans Health Administration (VHA). VHA's current strategic emphasis is provided by the "Eight for Excellence" framework, comprising eight broad goals and associated strategies and initiatives. This overview article highlights selected Center activities supporting key goals and strategies in the Eight for Excellence initiative. Many of the Eight for Excellence goals emphasize continuous improvement in healthcare quality and safety. For example, Goal 1 broadly addresses continuous improvement in the quality and safety of health care for veterans, while Goal 5 calls for in- creased focus of VHA research and development activities on clinical and system improvements, including increased collaboration between VHA research and health care delivery and increased targeting of VHA health services research and the QUERI model to improve care delivery. These goals entail substantial overlap with our Cen- ter's core mission and activities: our portfolio of projects in research, technical assistance and train- ing are designed to strengthen VHA's ability to improve quality and safety through implementation of evidence-based practices. Center researchers are pursing improvement in tobacco use (Judith Katz-
