Research "push", long term-change, and general practice.

Area of Science:

• Health Services Research
• Sociology of Health
• Primary Care Implementation Science

Background:

• Intervention evaluations often overlook long-term implementation challenges.
• Understanding sustained intervention delivery in primary care is crucial for effective healthcare.

Purpose of the Study:

• To explore the long-term implementation of a primary care intervention throughout and beyond its trial lifespan.
• To identify factors influencing the sustainability of complex interventions in real-world settings.

Main Methods:

• Eight general practices (four intervention, four control) participated.
• Qualitative data collected via in-depth interviews with healthcare professionals and observations.
• Thematic analysis integrated with Normalization Process Theory (NPT) constructs.

Main Results:

• Macro-level policy influenced practice priorities, impacting perceived intervention sustainability.
• Sustained intervention routinization depended on individualized monitoring and tacit knowledge transfer.
• The intervention was not perceived as sustainable within the "whole system" due to competing priorities.

Conclusions:

• Findings highlight the interplay between macro-level factors and individual practices in intervention sustainability.
• Contributes to sociological theories of implementation and understanding outcomes of complex interventions.
• Provides insights into conditions and consequences of long-term implementation applicable to other contexts.
