The following are some resources to check out for developing a full fledged population health monitoring program.  They are under review for application to the surveillance program being developed.

Part 1.  Techniques – Machine Learning

Introduction

Machine learning is using your Big Data/EMR and software tools to develop routine methods for analyzing results.  Most recently, I produced a method for evaluating the top 20 ICDs (by groups I defined) for each of the ethnic groups in the EMR.  These lists were combined in a final table, with ethnics group listed side by side, in descending order for each, for the ‘hot diagnoses’, followed by rank, n and percent.  That SAS took about 1000 lines of programming and a minimum of 53 processes (according to the SAS info that is displayed during a run).

Machine Learning uses two methods–a supervised classification process and an unsupervised classification process.  Supervised classification is where you the researcher manually define the different groupings. For example, my ICD lists and sets are defined based upon personal impressions of ICDs that need to stand out more than they do with the predefined ICD groups defined at CMS.  My first group of ICDs is 135, my second 303.  These groups are to some degree subjective, and based upon clinical observations regarding priority healthcare issues.

Unsupervised classification is where the SAS itself analyzes the data and determines where clusters appear, with the clinical variables (parametric and non-parametric) used to define these clusters.  Although these are fairly easy to produce, they are not always logical and may link one outlier ICD in Group A to the cluster in group B, making the outcomes generated questionable.  There are hundreds of classifications to be tested in terms of ICD and ICD comorbidity relationships.  The following are few examples of these.

Most of these are available in full text form on the internet (sorry, no downloadable pdf copies for the moment, due to copyright concerns.)

Observational Studies=Data Mining

Introduction

I most often incorporate GIS into my work by using the raw data provided by EMR, reclassifiying it as need be, and adding longitude-latitude data whenever possible. This use of GIS may be considered an extension of increasing popular “Observations Studies” term and techniques now found in the literature.  A GIS study of the raw or freshly mined and slightly modified data may also be labelled an “ecological study.”

Comparative Effectiveness Research

CER is when treatment programs for several programs or facilities are contrasted and compared statistically.  This refers to database settings where the data source is several places, and in order to retain HIPAA compliance, the data is cleaned of the personal identifiers and other data, as specified by some program and/or HIPAA guidelines.  These guidelines are followed as much as possible by the researchers, but realize, full compliance is difficult when the restricted data is essential to the study process itself, such as 5digit zip code identification and even street and house number data.  CER involves institutions cross-comparing their healthcare results and performance.  These measures are often implemented as part of the meaningful use program as well.
