Statistics Section Chair |
Dear Statistics Section members,
As you now are all well aware, because of the devastating situation in New Orleans, the APHA 2005 Annual Meeting & Exposition has been moved. Our thoughts and prayers are with all Gulf Coast residents, especially our Section members, who have suffered great losses due to this terrible disaster. We know that rebuilding will be difficult, but as a Section we want to lend our support and help in any way possible.
I also want to make sure that everyone is still on board for the 133rd Annual Meeting and Exposition to be held in Philadelphia, Dec. 10 – 14, 2005. APHA is currently negotiating with several hotels with regard to its relocation of hotel reservations and will advise all attendees shortly. We appreciate everyone’s continued patience, understanding and support. To obtain updates on the new location please go to <www.apha.org
APHA is also working on updating this year’s meeting program to address the public health emergency across the Gulf Coast, relief efforts and rebuilding of communities and the public health infrastructure. As such, I believe that the Annual Meeting will provide an important opportunity for the public health community to collaborate, share across disciplines and construct long-term solutions to best address this tragedy.
I again want to send the Section’s congratulations to our most recent 2005 Statistics Section Award Winners. Martin Weinrich did a great job chairing the selection process. The 2005 winners will be honored on Tuesday, Dec. 13, 2005: 2:30 p.m.-4:00 p.m. during the Lowell Reed Lecture, Spiegelman and Statistics Section Awards Sessions. 2005 Award Winners

Statistical and Modeling Techniques for Health Outcomes Research
Health outcomes research involves the collection and analysis of data that serves to provide evidence demonstrating the quality of medical care and public health programs. The assessment of patient-reported outcomes in clinical and health survey research has increased dramatically over the past several decades. Evaluations of symptoms, health status, quality of life and patient satisfaction are now primary and secondary outcomes in many clinical trials and observational studies. As indices and markers of therapeutic benefit and risk, these measures must be sensitive to differences that fall within a patient's operative range. Health care providers who must often prioritize resources across their members and among different conditions require a definitive metric. These evaluations typically use scales that have been developed to compare and contrast functioning relative to a given performance standard. To comprehensively evaluate the effectiveness of preventative programs and therapeutic interventions, investigators need to measure patient outcomes with the precision and accuracy that will allow for the detection of health improvements and health decrements that are important to the patient. The purpose of this session is to explore the various statistical, measurement and modeling techniques which can be used to evaluate the effectiveness of therapeutic interventions and prevention programs.3137.0: Monday, Dec. 12, 2005: 10:30 a.m.-12:00 p.m., Oral

Statisticians and De-Identifying Protected Health Information for HIPAA
The Health Insurance Portability and Accountability Act of 1996 (HIPAA) is mostly known among health care providers and researchers for repercussions of its Privacy Rule on work practices. HIPAA has had great impact on public health research due to restrictions on access to databases with any of the 18 Protected Health Information (PHI) variables. Most statisticians are aware of HIPAA because of required human subjects training and changes in database sharing, data use agreements, and security policies.
However, an important component of the HIPAA Privacy Rule is:The second way to de-identify PHI is to have a qualified statistician determine, using generally accepted statistical and scientific principles and methods, that the risk is very small that the information could be used, alone or in combination with other reasonably available information, by the anticipated recipient to identify the subject of the information. The qualified statistician must document the methods and results of the analysis that justify such a determination
Moreover, the de-identifier must not “disclose the key or other mechanism that would have enabled the information to be re-identified”; this includes not divulging pseudo-random number algorithms or seed values.
The two phrases in the quoted text, “very small
[risk]”and “qualified statistician
”, are examined further.
The HIPAA Rule does not quantify “very small,” but the Subcommittee on Disclosure Limitation Methodology of the Federal Committee on Statistical Methodology has provided an oft-cited 1994 working paper on the issue (FCSM, 1994). The working paper cites the National Center for Education Statistics Standard for Maintaining Confidentiality (IV-01-91): ‘In reporting on surveys and preparing public-use data tapes, the goal is to have an acceptably low probability of identifying individual respondents.’ The standard recognizes that it is not possible to reduce this probability to zero.” Although a specific probability is not stipulated, the standard does state that “cells be based on at least three unweighted observations and subsequent tabulations (such as crosstabulations) must not provide additional information which would disclose individual identities.”
The U.S. Office of Personnel Management defines two general schedule positions, Statistician (GS-1530) and Mathematical Statistician (GS-1529), with different qualification standards, which may add to the confusion. The educational requirements of the two positions each dictate as few as six semester hours (about two courses) in statistics with enough hours in mathematics (nine for statistician and 18 for mathematical statistician; details at OPM links below).
However, upon closer examination, the actual text of the Rule itself (Section 164.514(b)(1)) does not mention “statistician” but instead says “a person with appropriate knowledge of and experience with generally accepted statistical and scientific principles and methods for rendering information not individually identifiable.” The more widely disseminated interpretations use the phrase “qualified statistician” defined as “a person with appropriate knowledge of and experience with generally accepted statistical and scientific principles and methods for rendering information not individually identifiable” (NIH, 2005).
Finally it is important to note that, if the de-identification was not properly performed or the probability was not small enough, some believe statisticians may
be subject to prosecution (Dressler, 2005), since individuals in addition to covered entities have been charged and sentenced for infractions. However, a 2004 Seattle case of individual prosecution involved malicious identity theft. Furthmore, this summer a Department of Justice memorandum seems to indicate HIPAA only applies to covered entities not individuals (Pear, 2005).
Thus, public health statisticians who otherwise think of themselves as “qualified statisticians” may want to re-evaluate their training and experience with regard to the HIPAA Privacy Rule and their own risk exposure until the issue is resolved definitively.References:
