Looking Back, Looking Forward: A Study Protocol for a Mixed-Methods Multiple-Case Study to Examine Improvement Sustainability of Large-Scale Initiatives in Tertiary Hospitals

Background Hospitals invest extensive resources in large-scale initiatives to improve patient safety and quality at an organizational level. However, initial success, if any, does not guarantee longer-term improvement. Empirical and theoretical knowledge that informs hospitals on how to attain sustained improvement from large-scale change is lacking. Aim The proposed study aims to examine improvement sustainability of two large-scale initiatives in an Australian tertiary hospital and translate the lessons into strategies for achieving sustained improvement from large-scale change in hospital settings. Design and Methods The study employs a single-site, multiple-case study design to evaluate the initiatives separately and comparatively using mixed methods. Semi-structured staff interviews will be conducted in stratified cohorts across the organizational hierarchy to capture different perspectives from various staff roles involved in the initiatives. The output and impact of the initiatives will be examined through organizational documents and relevant routinely collected organizational indicators. The obtained data will be analyzed thematically and statistically before being integrated for a synergic interpretation. Implications Capturing a comprehensive organizational view of large-scale change, the findings will have the potential to guide the practice and contribute to the theoretical understandings for achieving meaningful and longer-term organizational improvement in patient safety and quality.
