The Safer Delivery of Surgical Services Program (S3): Explaining Its Differential Effectiveness and Exploring...

Area of Science:

• Healthcare Improvement Science
• Surgical Quality Management
• Implementation Science

Background:

• The S3 Program tested combined culture and system interventions against single approaches for surgical quality improvement.
• Quantitative data supported the superiority of combined interventions.
• This qualitative study explores the underlying reasons for the observed success and implementation dynamics.

Purpose of the Study:

• To analyze challenges in surgical quality improvement interventions.
• To explain the differential success of various intervention strategies.
• To understand the 'why' and 'how' of intervention effectiveness in healthcare.

Main Methods:

• Conducted semistructured interviews with 23 hospital staff and 11 research team members.
• Employed the constant comparative method for qualitative data analysis.
• Aligned identified themes with the S3 program's underlying theory.

Main Results:

• Combined interventions led to greater awareness and action, supporting the S3 hypothesis.
• Unforeseen implementation differences amplified the performance gap between intervention types.
• Intensive expert support was crucial for the success of more ambitious, combined interventions.

Conclusions:

• Findings support the S3 hypothesis, explaining the causal link between interventions and outcomes.
• Implementation strategies and external factors critically influence intervention success.
• Contextual challenges highlight implications for the replicability and sustainability of improvement programs.
