BACKGROUND: Top managers transformational leadership is associated with significant influence on subordinates. Yet little is known about the extent to which top managers transformational leadership influences middle managers implementation leadership and, ultimately, frontline staff delivery of evidence-based health care practices. PURPOSE: To test a multilevel leadership model examining the extent to which top managers transformational leadership, as mediated by implementation leadership of middle managers (i.e., those who supervise direct clinical services), affects staff attitudes toward evidence-based practices (EBPs) and their implementation. METHODOLOGY/APPROACH: We used data collected in 2013 from 427 employees in 112 addiction health services programs in Los Angeles County, California. We relied on hierarchical linear models with robust standard errors to analyze multilevel data, individuals nested in programs. We conducted two path models to estimate multilevel relationships with two EBPs: contingency management and medication-assisted treatment. RESULTS: Findings partially supported our theory-driven multilevel leadership model. Specifically, results demonstrated that middle managers implementation leadership mediated the relationship between top managers transformational leadership and attitudes toward EBPs. At the same time, they showed the mediated relationship for delivery of contingency management treatment was only marginally significant (standardized indirect effect = .006, bootstrap p = .091). We did not find a mediation effect for medication-assisted treatment. DISCUSSION: Findings advance leadership theory in health care, highlighting the importance of middle managers implementation leadership in transmitting the influence of top managers transformational leadership on staff attitudes toward EBPs. The full path model shows the extent to which transformational leadership may influence staff implementation of innovative practices as mediated through staff attitudes toward EBPs and middle managers implementation leadership. PRACTICE IMPLICATIONS: Our findings have implications for developing a multilevel leadership approach to implementation in health care. Leadership development should build on different competencies based on managers level but align managers priorities on the same implementation goals.

Background

Utilization of specialty care may not be a discrete, isolated behavior but rather, a behavior of sequential movements within the health care system. Although patients may often visit their primary care physician and receive a referral before utilizing specialty care, prior studies have underestimated the importance of accounting for these sequential movements.

Methods

The sample included 6,772 adults aged 18 years and older who participated in the 2001 Survey on Disparities in Quality of Care, sponsored by the Commonwealth Fund. A sequential logit model was used to account for movement in all stages of utilization: use of any health services (i.e., first stage), having a perceived need for specialty care (i.e., second stage), and utilization of specialty care (i.e., third stage). In the sequential logit model, all stages are nested within the previous stage.

Results

Gender, race/ethnicity, education and poor health had significant explanatory effects with regard to use of any health services and having a perceived need for specialty care, however racial/ethnic, gender, and educational disparities were not present in utilization of specialty care. After controlling for use of any health services and having a perceived need for specialty care, inability to pay for specialty care via income (AOR = 1.334, CI = 1.10 to 1.62) or health insurance (unstable insurance: AOR = 0.26, CI = 0.14 to 0.48; no insurance: AOR = 0.12, CI = 0.07 to 0.20) were significant barriers to utilization of specialty care.

Conclusions

Use of a sequential logit model to examine utilization of specialty care resulted in a detailed representation of utilization behaviors and patient characteristics that impact these behaviors at all stages within the health care system. After controlling for sequential movements within the health care system, the biggest barrier to utilizing specialty care is the inability to pay, while racial, gender, and educational disparities diminish to non-significance. Findings from this study represent how Americans use the health care system and more precisely reveals the disparities and inequalities in the U.S. health care system.
