Healthcare Process Improvement using RTLS

Project Objectives

The goal of this study is to develop a real-time location tracking protocol that will improve the healthcare delivery process by minimizing missed opportunities caused by work delays.

Project Approach

  • Use the RTLS-based nursing activity analysis system at an ICU at the University Hospital
  • Validate location system performance against manual observation of nursing activity.
  • Correlate nursing activity metrics against patient outcomes as measured by Sequential Organ Failure Assessment (SOFA) score

Inventory Management of Blood Supply Chain

Project Objectives

  • Reduce total cost along blood supply chain
  • Total cost = Fixed transportation cost + variable purchasing cost + shortage cost + holding cost + outdating cost

Project Outcomes

  • Developed four heuristic policies (Order-up-to-level, Modified order-up-to-level policy, Last value method and Weighted mean variance policy) that can be implemented easily using an Excel spreadsheet
  • Policies were able to reduce blood shortage by 17% and blood outdating by 23%
  • Can act as decision support systems to hospital administrators

Tracking Alzheimer’s Disease Progression Path

Project Objectives

  • To use neuroimaging technique to track AD progression especially for serving as biomarkers in clinical trials, it is desirable to have global indices which can summarize numerous complicated imaging features.
  • In this research, we propose a new global index, derived from non-linear dimension reduction of brain MRI features, to track AD progression over time.

Smart Dynamic Appointment Scheduling Rules

Project Objectives

  • Motivated by real-life case of a family medicine clinic in the US
  • Objectives are to improve resource utilization and patient satisfaction

Project Outcomes

  • Stacking approach achieved the best classification accuracy for no-show risk prediction followed by gradient boosting
  • Proposed smart appointment scheduling rules outperformed the existing approach significantly in terms of patient waiting time, nurse utilization and provider utilization
