Impact of system performance on care quality

Figure 4. Data delivery delay

• Analysis of performance data of UPHS telemedicine systems for 300+ CHF patients over 5+ years 
• Suffer long delays (>24 hrs) due to network problems 
• Caused delay in intervention, and even rehospitalization

Figure 5. Personalized early warning model

• Improve efficiency of interventions 
• Develop personalized models based on patient history 
• Apply learning models to detect early symptoms

Security for Homecare Medical Devices

• Wireless medical devices lack sufficient protection 
• Utilize spatio-temporal patient usage patterns 
• Integrating patient safety model in access control
