Re: [openhealth] Suppressing Sensitive Info From Free Text

2007-03-04 Thread Will Ross
John,

In this use case, the record is not held by the health care site  
where the patient's confidential information is secure and private,  
but in a community repository operated by a Regional Health  
Information Organization (RHIO).   Operating edge proxies which host  
access to uploaded copies of patient records, the RHIO seeks an  
appropriate compromise between routine access to patient health data  
and protection of sensitive information.   Unfortunately, the  
originating records combine both routine and sensitive patient  
information in a monolithic free text format, hence the search for an  
appropriate NLP scrubbing step prior to export.

Did I answer your question?

With best regards,

[wr]

 Will,
 Could you give a little more information on the structure of such a
 clinic? I am not aware of any practices with a protected,
 physician-only area more sheltered than general circulation.

 Once I produce my part of a record it is available to other  
 physicians,
 nurses, scheduling and billing folk. Confidentiality requires the  
 whole
 team to protect sensitive information.

 How will a general circulation patient record be used?

 Further:
 There are difficulties far beyond the obvious risk of something  
 slipping
 through in free text.

 Take the HIV example:
 A medication list could contain medications used only for HIV.  
 (Likewise
 an allergy list referring to any such a medication.) Diagnoses that
 herald underlying HIV infection would have to be caught. Likewise
 laboratory testing, such as CD4 counts, X-ray diagnoses, pathology
 reports. Specialty clinics that a patient may be referred to (and
 references to any reports from such sources).

 Unless the record is very impoverished to begin with, it will probably
 be leaky by its very nature. Effort might be better spent at educating
 the entire staff on their ethical responsibilities.

 Technology could be useful for detecting inappropriate patterns of  
 use.

Thank you for your response, Will.

I fear I am being intentionally obtuse. But I get stuck at this 
distinction between routine access and sensitive information. Perhaps 
the RHIO gets to define the distinction? I think others have pointed out 
that one person may consider information sensitive that another may 
regard as routine, or even public.

I will withdraw to learn more about the RHIO.  :-)

Will,

It is not a good idea to have sensitive information in
free text. If you do, it should not go to  general
circulation, right?

How can one extract such info from free text? One way
is to remove such words from free text files using a
macro of some sort. FInd and replace can be used to
remove words like HIV with a blank?

There cannot be an automated solution to this, unless
it is cutting edge! ( ..or so we like to think to
cover our ignorance!)

I wonder if we have adequate knowledge as to what
constitutes sensitive information to patients. A
good study is needed

As automation ...
I think this is regarded everywhere as a hard problem.

In the UK I believe it would be generally regarded as if not actually
impossible, at least unfeasibly hard by a very large margin.


As semi-automation, presenting line after line to a human, and offering
hints I suppose there is scope.


If HIV status is held as a code or information in a field, then this
would just be a reporting problem, but one can't rely on it not being
repeated in the free text, clinical info echoed back in lab results etc.

Difficult.


On the question of patients and confidentiality, the (Ross) Anderson
Guidelines as published in the BMJ some years ago are probably good.

In general, this falls under a number of natural language processing
tools and specific steps toward tokenizing, chunking, part-of-speech
tagging, classifying (e.g. to vocabularies or concept identifiers),
matching, anonymizing/de-identifying, etc.

The two tools I've worked with a little in the past are:

1) GATE - General Architecture for Text Engineering, developed at the

2) Project DIAsDEM and the DIAsDEM workbench developed by a great
group, including Karsten Winkler, in Germany
http://wwwiti.cs.uni-magdeburg.de/~graubitz/diasdem/

These more are less are a suite of tools containing a number of
individual components to perform the various NLP tasks, in some
sequence (steps can be recorded and set as a macro or batch) and with
customization for using language specific knowledge bases (e.g. names
derived from a US Census database) or UMLS concept identifiers.

A couple of example projects using these kinds of tools is the caTIES
application (http://caties.cabig.upmc.edu/index.html) for extraction
and classification of free text pathology reports and the RODS
biosurveillance application, also from the Univ of Pittsburgh
(http://openrods.sourceforge.net/), that takes free text and ICD-9
data for syndromic classification.

A specific NLP approach to HIV/AIDS notes performed at Columbia is
here (the MedLEE or Medical Language Processing):

The only acceptable answer would be Maury's option 3.  The patient decides.
Anything else would be be inappropriate.

And not just HIV status.  The patient, and only the patient, should have the
right to determine who has access to anything that the patient might
consider sensitive.   And only the patient can determine what is or is not
sensitive.

Agreed.  Such an action would at least have to have approval of a local 
HIPAA board.
How would one prove it is reliable at removing protected information? 
If it is
an algorithm, the algorithm would need local approval.

 1. How good does it have to be?  Is 5% leakage of sensitive information OK?
 2. Another view: ALL of the information is sensitive.
 3. Another view: The patient MUST have input as to who can see what.

Dear 80n,

This is, in fact, the use case in discussion.

Assume the patient has agreed to suppress detail x from circulation  
beyond his/her physician's eyes in the local free text based records  
system.   What are the best FOSS tools to publish to the general  
circulation records environment a correctly edited version of a text  
file?

With best regards,

That is the reason for the patient consent in the HIPAA regulations.  In 
my opinion, the
patient would need to review the data to approve its release.  The usual 
escape clause
is for the data to be used in the normal care of the patient  But if it 
is for some
other purpose, then it needs specific patient consent.   But a local 
HIPAA board
should be able to provide more precise guidance.   The general accurate 
suppression
of sensitive information would seem to me to be impossible.
