Patient Experience (n = 1) |
Goff, 2019 [57] | Cross-sectional study |
Presence of a designated quality champion (“Yes/No” survey item) |
Average patient experience scores of clinics that are part of the Massachusetts Health Quality Partners (MHQP) | ANOVA | Test statistics not reported (Mean difference = 0.09 favouring presence of a champion) | .29 |
Provider Outcomes (n = 1) Conclusion: There is a single study suggesting that the use champions is related to improvements in provider outcomes related to innovation use | |||||||
Satisfaction with practice (n = 1) |
One study, two reports: |
Interrupted time series | Endorsed by champions (three items rated at a 6-point Likert scale based on Mullins et al. [98] | Reported ergonomic advantage 1-month post-introduction of transfer boards | Structural equation model using a maximum likelihood method | Path coefficients (95 CI) = 0.63 (.0664–1.1936) | < 0.05b |
System/Facility Outcomes (n = 3) Conclusion: Across three studies, there is a trend suggesting that use of champions is related to improvement in system/facility outcomes related to innovation use | |||||||
Hospital quality of care indicators (n = 1) |
Foster, 2017 [56] | Non-controlled before and after study | An average of 0.1 champion fellows in 1160 hospitals (number of champion fellows) | Weighted composite score of quality of care—occurrence of 10 harm topics (e.g. readmissions) for 1 month | Multivariate linear regression | Adjusted effect over time: β = − 0.9 (negative β = more effective in this study) | .008 |
Access to training for alcohol cessation screening and advice (n = 1) |
Patton, 2013 [69] | Cross-sectional study | Presence of champion (“Yes/No” survey item) | Emergency staff’s access to training for screening for alcohol consumption | Chi square | χ2 = 36.64 | < 0.001 |

aIn this study, groups exposed to only nurse champions had the highest risk-standardized mortality rate (RSMR; RSMR = 16.2); hence, it was the reference variable
bThe authors reported a path coefficient that they stated is significant at a p-value of 0.1. Manual calculation of the 95% CI was done by JES to determine significance of both ergonomic advantage and intention to use at a p-value of .05
cOther outcomes were not considered in analysis
