Explaining variable effects of an adaptable implementation package to promote evidence-based practice in primary...

Area of Science:

• Healthcare implementation science
• Primary care quality improvement
• Behavioral science in medicine

Background:

• Implementing evidence-based guidelines in UK primary care faces challenges due to system pressures and competing recommendations.
• Adaptable implementation packages can address common barriers to achieving multiple guideline recommendations efficiently.
• A package of interventions (audit and feedback, educational outreach, reminders) with behavior change techniques was developed to target key indicators.

Purpose of the Study:

• To evaluate the effectiveness and cost-effectiveness of an adaptable implementation package in UK primary care.
• To explore the impact of the package on social processes using Normalisation Process Theory (NPT) and behavioral determinants using the Theoretical Domains Framework (TDF).

Main Methods:

• A prospective, multi-method process evaluation was conducted in eight UK primary care practices.
• Data collection included observational, administrative, and interview data, guided by NPT and TDF.
• Survey data assessed fidelity of implementation across trial and process evaluation practices.

Main Results:

• The implementation package led to a significant, cost-effective reduction in risky prescribing.
• Variable integration into practice routines and organizational factors influenced the package's success.
• Impacts on team-based determinants were limited, and delivery delays/unintended consequences affected engagement.

Conclusions:

• The adaptable implementation package showed partial success in UK primary care, primarily due to variable integration and delivery challenges.
• Understanding practice routines, behavioral determinants, and delivery processes is crucial for optimizing implementation strategies.
• Further research is needed to refine adaptable packages for broader effectiveness in primary care settings.
