Moving from fee-based to performance-based (HIT)

  • Data-intensive industry: capture, store, process, and communicate information to decision makers for better coordination of care 
  • Healthcare is a complex and multidisciplinary domain (e.g., complex workflows, HIPAA)
  • medical condition
  • treatment options
  • providers, payers & regulators

Is it a design problem?

Design Objectives (from the design challenge):

Source: Health Design Challenge

  1. Improve the visual layout and style of the information from the medical record

2. Create a human-centered design that makes        it easier for patient to manage their health

3. Enable health professionals to more effectively        understand and use patients' health information

4. Help family members and friends care for their loved ones

Relevant? What makes it relevant?

Relevant. What makes it relevant?

Latest vital signs? Temperature, blood pressure, heart rate, respiratory rate, O2 saturation, etc.

Current medications? dosages, timing, and priority (routine/PRN), previous medication, etc.


Pre-existing conditions?


It depends!

Different users need different information

Why so?

Irrelevant information influence user’s judgment when processing information (Silver, 1991)

Decision aids can benefit users (cognitive effort & decision quality) (Haubl and Trifts, 2000)

 Success depends on the faithfulness of the representations (Burton-Jones & Grange, 2012)

An info Prob. - Psychological foundation

Cognitive research plays an important role in the development of information systems since these systems are representations of real-world tasks (Davern, Shaft, & Te'eni, 2012)

Different observers may choose to model the world differently (Wand & Weber, 1990)

Information systems reflect how humans organize the knowledge about a domain (Parsons, 1996)

Although the surface structure (e.g., user interface, interaction) of an information system may vary, the deep structure (e.g., domain representation) should be a faithful representation of the world that is being represented (Burton-Jones & Grange, 2012).
(...Information Architecture...) 

Cognitive science provides theories and models of knowledge organization, concepts, categorization, and classification (Lakoff, 1987; Eleanor Rosch, 1999; Smith & Medin, 1981)

Psychological foundation

a) Ability to predict unobservable attributes (inferential utility)

b) Optimize information processing and transfer (cognitive 


The ability to predict attributes of instances of a class, increases as the scope of the class decreases.






Concepts provide two primary functions: cognitive economy (of resources) and inferential utility

Information Supply Chain (ISC)  (Sun and Yen 2005)

Need for reliable and timely information to make information-driven or evidence based decisions (Friede, Blum et al. 1995)

Application: IR

User profile could be inferred from:

  • The whole search history to model long term user interests (Tamine-Lechani et al., 2008)
  • Recent search history to model short term user interests (e.g., session) (S. Sriram et al., 2004)
  • The user profile is represented as a graph of the most relevant concepts of ontology in a specific search session and not as an instance of the entire ontology -- a weighted graph of semantically related concepts of a predefined ontology (Daoud et al., 2009)

IR/HIS - Psychology

Evidence-based clinical practice integrates the individual clinical expertise with clinical evidence from systematic research, leading to more effective and efficient diagnosis (Sackett, 2000). 

Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm.

Classification is one approach to handling large volumes of data. Organize information by classifying documents into the best matching concept(s) from a predefined set of concepts.

Implications: Crowdsourcing

Citizen Science:

"non-experts often lack the knowledge to identify species, they may opt not to participate or may provide inaccurate data by accidentally misidentifying something." 

Parsons, J., Lukyanenko, R., & Wiersma, Y. (2011). Easier citizen science is better. Nature, 471(7336), 37-37.

Any other applications?
