System Impact Measures

The Problem

The IPI System serves as a novel infusion care decision support tool for pharmacists and nurses in the hospital setting.  The infusion drug alerts data and knowledge sharing within this community of practice, provide clinicians with in-depth information on the infusion practice in each of the participating hospitals.  It is important to understand and identify the drug alert and user usage patterns, and clinical In order to qualify the impact of the adoption of the IPI System.


For each selected hospital in the community:

1.    Analyze the top 10 drugs over time; identify drugs of most interest by individual hospitals and the community as a whole

2.    Analyze the reduction in the number of alerts per device per drug of interest and its change over time including their movement in the top 10 drugs

3.    Analyze the number and timing of drug limit library updates and identify their potential impact.

4.    Analyze the compliance percentage over time (by hospital

5.    Compare and associate the aforementioned impact measures and their implication on clinical practice or infusion care delivery 


Drug alert analysis on number, frequency and pattern over time will be performed on selected hospitals. Selection will be based on their membership history, activeness in the community and main user profiles. Research will be conducted on the methods related to pattern and clustering analysis

Potential Impact

Well defined impact measures of the IPI System can demonstrate the values created by this specific community of practice and all the tools available online. The process of identifying and defining IPI System impact can further helps cast other important research questions pertinent to the adoption of this novel online system and its community. Potentially one can create an index of system impact based on the aforementioned measures for system refinement, improvement, and design of similar e-communities of practice in the future.
