3. Model 3 Calculation Engine: • The model estimates the potential patient service outcome and patient health outcome benefits of deploying CPOE across a nation or an entity (e.g. hospital or health authority) thereby reducing the number of adverse drug events (ADEs) in both inpatient and outpatient settings. • The inpatient component of the model takes the total number of inpatient hospital days for a nation or entity and then converts them into susceptible patient days. • The outpatient component of the model takes the number of total annual outpatient visits and estimates the number of susceptible visits that present a risk of an ADE. • The model then estimates the number of preventable ADEs with current and future CPOE adoption. The model uses the difference in preventable ADEs to estimate reduced bed days and deaths avoided. • Monte Carlo simulations are used to generate range estimates of reduced ADEs, reduced bed days and deaths avoided in response to increased CPOE adoption.
