An Interprofessional Organization Change Process To Reduce Catheter-Associated Urinary Tract Infections, Bolatito Owolabi

Walden Dissertations and Doctoral Studies

This organization change process initiative addressed a critical safety practice gap regarding catheter-associated urinary tract infection (CAUTI) prevention in a 450-bed acute care facility. This gap was recognized based on evidence that the facility’s CAUTI Standardized Infection Ratio (SIR) was above the national benchmark—and daily necessity assessment compliance of only approximately 50%. This gap was attributed to an organizational interprofessional culture, which hindered timely device removal. Prolonged catheter dwell times increase patient morbidity, extend hospital stays, and expose the organization to severe financial penalties. The project aimed to safely reduce device dwell times by structurally empowering bedside nurses. I used …

Effective Strategies To Implement Energy-Efficient Practices In Enterprise Cloud Data Centers: A Qualitative Pragmatic Inquiry, Joshua Tremayne Campbell

Walden Dissertations and Doctoral Studies

Cloud computing has increased electricity use in data centers, leading to higher costs and a larger carbon footprint.
