In healthcare and related fields, there is often a gap between research and practice. Scholars have developed frameworks to support dissemination and implementation of best practices, such as the Interactive Systems Framework for Dissemination and Implementation, which shows how scientific innovations are conveyed to practitioners through tools, training, and technical assistance (TA). Underpinning those aspects of the model are evaluation and continuous quality improvement (CQI). However, a recent meta-analysis suggests that the approaches to and outcomes from CQI in healthcare vary considerably, and that more evaluative work is needed. Therefore, this paper describes an assessment of CQI processes within the Substance Abuse and Mental Health Services Administration’s (SAMHSA) Technology Transfer Center (TTC) Network, a large TA/TTC system in the United States comprised of 39 distinct centers. We conducted key informant interviews ( n = 71 representing 28 centers in the Network) and three surveys (100% center response rates) focused on CQI, time/effort allocation, and Government Performance and Results Act (GPRA) measures. We used data from each of these study components to provide a robust picture of CQI within a TA/TTC system, identifying Network-specific concepts, concerns about conflation of the GPRA data with CQI, and principles that might be studied more generally.
