RESUMO
Maximizing the quality and benefits of newly established chiropractic services represents an important policy and practice goal for the US Department of Veterans Affairs' healthcare system. Understanding the implementation process and characteristics of new chiropractic clinics and the determinants and consequences of these processes and characteristics is a critical first step in guiding quality improvement. This paper reports insights and lessons learned regarding the successful application of mixed methods research approaches-insights derived from a study of chiropractic clinic implementation and characteristics, Variations in the Implementation and Characteristics of Chiropractic Services in VA (VICCS). Challenges and solutions are presented in areas ranging from selection and recruitment of sites and participants to the collection and analysis of varied data sources. The VICCS study illustrates the importance of several factors in successful mixed-methods approaches, including (1) the importance of a formal, fully developed logic model to identify and link data sources, variables, and outcomes of interest to the study's analysis plan and its data collection instruments and codebook and (2) ensuring that data collection methods, including mixed-methods, match study aims. Overall, successful application of a mixed-methods approach requires careful planning, frequent trade-offs, and complex coding and analysis.
RESUMO
Fear of engendering addiction is frequently reported as both a provider and a patient barrier to effective pain management. In this study, a clinical scenario ascertained nursing staff members' usual practice in addressing addiction fears for patients with concerns about the addictive potential of pain medication. One hundred forty-five Veterans Health Administration nursing staff members from eight ambulatory care sites were queried to identify variables associated with proclivity to address patient fears about addiction risks in a population where pain is prevalent and the risk for substance abuse is high. Regarding addressing addiction concerns, 66% of nursing staff were very likely, 16% somewhat likely, 9% unsure, 6% somewhat unlikely, and 2% very unlikely to take action. Health technicians were less likely to address addiction concerns than registered or licensed vocational nurses (odds ratio [OR] 0.116; p=.004). Nursing staff with more years' experience (OR 1.070; p=.005) and higher levels of self-efficacy/confidence (OR 1.380; p=.001) were more likely to engage in discussions related to addiction risks. Targeted efforts to improve pain management activities should focus on retaining experienced nursing staff in initial assessment positions and improving the skills and confidence of less experienced and less skilled staff.
