Abstract

Background: The Plan-Do-Study-Act (PDSA) cycle is fundamental to many quality improvement (QI) models. For the approach to be effective in the real-world, variants must align with standard elements of the PDSA. This study evaluates the alignment between theory, design and implementation fidelity of a PDSA variant adapted for Nigeria's health system performance improvement. Methods: An iterative consensus building approach was used to develop a scorecard evaluating new conceptual indices of design and implementation fidelity of QI interventions (design and implementation index, defects and gaps) based on Taylor's theoretical framework. Results: Design (adaptation) scores were optimal across all standard features indicating that design was well adapted to the typical PDSA. Conversely, implementation fidelity scores were only optimal with two standard features: prediction-based test of change and the use of data over time. The other features, use of multiple iterative cycles and documentation had implementation gaps of 17 % and 50 % respectively. Conclusion: This study demonstrates how both adaptation and implementation fidelity are important for success of QI interventions. It also presents an approach for evaluating other QI models using Taylor's PDSA assessment framework as a guide, which might serve to strengthen the theory behind future QI models and provide guidance on their appropriate use.
