While the various methods and technologies associated with Big Data and Data Science offer exciting potential to dramatically improve the business and clinical insight available to healthcare professionals (both clinical and administrative), there is no shortage of hype associated with them either.

Oftentimes what is missing from the discussion is an objective look at the benefits and drawbacks as well as the strengths and weaknesses of big data and data science, free of the promises and hyperbole often associated with vendor and consultant pitches.

I recently came across this slide deck (see below) by Diego Kuonen that provides a professional statistician’s thorough, hype-free view on “Big Data” and “Data Science”. In the presentation, the author “illustrates the connection between data science and statistics, and highlights some challenges and opportunities from a statistical perspective” (quoted text taken from abstract).

As listed on the overview page, the four main objectives of the presentation are to:

  1. Demystify big data hype.
  2. Demystify data science hype.
  3. Discern between data science and statistics
  4. Discuss opportunities in data science and big data

For a solid overview of the fundamentals of Big Data and Data Science, I highly recommend this deck… you’ll then be prepared to see through the hype and have a truer understanding of these important concepts in Healthcare Analytics.


Checklist 610wHealthcare Organizations (HCOs) are undergoing an incredible amount of change. Whether addressing regulatory changes, financial pressures, or quality and performance issues, HCOs require insight into their business and clinical operations to identify where problems exist, and to evaluate efforts to address those problems.

In my recent article on SearchHealthIT.com, I share a few common capability-maturity models for business intelligence and analytics that can be applied to healthcare (including Tom Davenport’s DELTA model). In the article, I also discuss a five-point analytics “systems check” healthcare organizations should periodically use to ensure that the needs of the users and the business are still in alignment, and that any major requirements or assumptions have not changed.

The five main points of the analytics system-check are:

  • Clearly defined and communicated business goals/objectives.
  • Well understood needs of stakeholders.
  • Appropriate human and technical resources are in place, and in the right place.
  • Necessary technology is available.
  • Analytics are used to drive decision making.

I invite you to read the entire article on SearchHealthIT.com for full details on the capability maturity models as well as the five-point analytics systems-check.
