Can systematic implementation support improve programme fidelity by improving care providers' perceptions of...

Area of Science:

• Implementation Science
• Healthcare Management
• Mental Health Services Research

Background:

• Understanding implementation factors is crucial for addressing inadequate outcomes in evidence-based practice adoption.
• Limited knowledge exists on the relationship between implementation factors and outcomes, particularly in later implementation stages.

Purpose of the Study:

• To assess the association between implementation success (programme fidelity) and care providers' perceptions of implementation factors.
• To investigate the impact of systematic implementation support on these perceptions.

Main Methods:

• Cluster-randomized design involving mental health clinics receiving or not receiving implementation support.
• Programme fidelity and care provider perceptions (Implementation Process Assessment Tool) were measured at baseline and 18 months.
• Descriptive statistics and linear mixed-effect analysis were used to test associations and group differences.

Main Results:

• Care provider perceptions of implementation factors correlated with fidelity after 18 months (B=.7, p=.004).
• Positive perceptions of implementation factors were significantly higher in the group receiving implementation support (t=2.22, p=.028).

Conclusions:

• Implementation support positively influences care provider perceptions, which in turn is associated with higher programme fidelity.
• Continuous attention to care provider perceptions throughout implementation is vital for improving success.
• Further research is needed to validate findings and understand decision-making mechanisms for sustained high fidelity.
