EHR Data Quality

Current EHR and HIT thinking places significant value on immediate and downstream use of EHR data.   The expected benefits of interoperability, clinical decision support, and data analytics all depend on accurate EHR data.  Yet, somehow, data quality has not gotten the attention that it should.   While clinical researchers are increasingly focused on improving phenotyping algorithms […]

Having been away for much of the last few weeks, it is good to be home again contemplating summer projects.   As always, there are lots of things to choose from.

Two weeks ago I wrote about the value of EHR timelines and audit trails. Today’s post takes that discussion a little further by demonstrating various ways of keeping track of data accesses and changes in EHR data element values.   Of course, this functionality is useful for any clinical database that might be covered under HIPAA.  […]

After enduring the usual software development delays, I am moving ahead with the data store evaluations mentioned in the post Databases a la Carte.   There are three immediate goals. The first is obtaining a deeper knowledge of MySQL, which is more or less a practice-makes-perfect situation.  Thus far, I have been getting by on my […]
