BackgroundAttempts have been made to reduce excessive laboratory test ordering; however, the problem persists and barriers to physician involvement in quality improvement (QI) remain. We sought to understand physician participation experience following a laboratory test overuse initiative supported by a QI coalition.MethodsAs part of a larger mixed-methods study, structured virtual interviews were conducted with 12 physicians. The Theoretical Domains Framework (TDF) and the Behavioural Change Wheel (BCW) were used to identify characteristics that influence physician behaviour change for QI leadership and participation and appropriate blood urea nitrogen (BUN) test ordering. A content analysis of physicians’ statements to the TDF was performed, resulting in overarching themes; relevant TDF domains were mapped to the intervention functions of the BCW.ResultsNine overarching themes emerged from the data. Eight of 14 TDF domains influence QI leadership and participation, and 10 influence appropriate BUN-test ordering behaviours. The characteristics participants described that promoted a change in their QI participation, leadership and appropriate BUN-test ordering were: QI education with hands-on training; physician peer mentorship/support; personnel assistance (QI and analytics) and communication from a trusted/credible physician leader who shares data and insights about the physician role in the initiative, clinical best practice and past project success. Other elements included: a simply designed initiative requiring minimal effort and no clinical workflow disruptions; revised order forms/panels and limiting test-order frequency when laboratory tests are normal. Additionally, various future intervention strategies were identified. For their initial initiative participation, physicians acknowledged coalition leader or member credibility was more important than awareness of the coalition.ConclusionsBased on physicians’ described perceptions and experiences, coalition characteristics that influenced their QI leadership and participation, and appropriate BUN-test ordering behaviours were revealed; these characteristics aligned to several TDF domains. The findings suggest that these behaviours are multidimensional, requiring a multistrategy approach to change behaviour.

Physicians have a vital role to play in health system transformation, and their committed involvement provides an opportunity for comprehensive improvement and change. Health care has been shifting to a team-based, integrated, and collaborative approach, with a greater expectation for physicians to engage and lead quality improvement (QI). However, there are many barriers to physician QI capability, participation, and leadership. A physician leader at a university and a provincial health care organization’s executive director recognized this challenge and developed an innovative coalition, the Strategic Clinical Improvement Committee, to build organizational capacity for physician-led QI. Six key principles and approaches underpin the coalition: QI as inseparable from care, accountability, a team approach, organic growth through training, academic credibility, and return on investment, including 14 enabler strategies. To date, achievements include the completion of over 60 physician-led QI projects, development of a summer health care improvement elective course, receipt of grants totaling $250 000, 16 QI papers published in peer-reviewed journals, and numerous projects shared nationally and internationally at conferences. The coalition has propelled a shift toward a physician-led improvement culture at the direct care level. The criticality of sustaining this culture of physician QI engagement and leadership will require balancing competing priorities, limited resources, and various other health system influences.

BackgroundA coalition (Strategic Clinical Improvement Committee), with a mandate to promote physician quality improvement (QI) involvement, identified hospital laboratory test overuse as a priority. The coalition developed and supported the spread of a multicomponent initiative about reducing repetitive laboratory testing and blood urea nitrogen (BUN) ordering across one Canadian province. This study’s purpose was to identify coalition factors enabling medicine and emergency department (ED) physicians to lead, participate and influence appropriate BUN test ordering.MethodsUsing sequential explanatory mixed methods, intervention components were grouped as person focused or system focused. Quantitative phase/analyses included: monthly total and average of the BUN test for six hospitals (medicine programme and two EDs) were compared pre initiative and post initiative; a cost avoidance calculation and an interrupted time series analysis were performed (participants were divided into two groups: high (>50%) and low (<50%) BUN test reduction based on these findings). Qualitative phase/analyses included: structured virtual interviews with 12 physicians/participants; a content analysis aligned to the Theoretical Domains Framework and the Behaviour Change Wheel. Quotes from participants representing high and low groups were integrated into a joint display.ResultsMonthly BUN test ordering was significantly reduced in 5 of 6 participating hospital medicine programmes and in both EDs (33% to 76%), resulting in monthly cost avoidance (CAN$900–CAN$7285). Physicians had similar perceptions of the coalition’s characteristics enabling their QI involvement and the factors influencing BUN test reduction.ConclusionsTo enable physician confidence to lead and participate, the coalition used the following: a simply designed QI initiative, partnership with a coalition physician leader and/or member; credibility and mentorship; support personnel; QI education and hands-on training; minimal physician effort; and no clinical workflow disruption. Implementing person-focused and system-focused intervention components, and communication from a trusted local physician—who shared data, physician QI initiative role/contribution and responsibility, best practices, and past project successes—were factors influencing appropriate BUN test ordering.
