Is it scientifically valid to use data for purposes for which they were not originally collected?
How comfortable are you with this idea? What is the alternative?
Today and next week
Learn some uses of secondary data Learn about sources of secondary data Understand possible effects of HIPAA on this type of research Describe biases commonly encountered in secondary data Describe frequently used research designs in health services
research. Define risk adjustment and why it is important in HSR; give
examples of methods Discuss rationale for methods to account for nesting or clustering
of data

TENET HEALTHCARE – 2002
Medicare Report Jan-Oct 2004 included these findings: – At Alvarado Hospital, prosecutors accused Tenet of running covert
kickback arrangements – Document requests were received from federal prosecutors in L.A. – False claims were uncovered and the company agreed to pay
$22.5M to settle allegations – Redding Medical Center was determined to be performing
unnecessary cardiac surgery – Tenet sold some holdings to Hospital Partners of America to
satisfy part of the 2003 settlement with federal officials – Whistleblowers were to receive over $8M
Whose data set is it anyway? Sharing raw data

Can you think of examples of secondary data analysis that you have read in the medical literature?
Any that have influenced your practice or your research direction?
Anything you would like to see investigated but have not yet found in the literature?
Secondary Data Exercise #1A Regional Trauma Center (which encourages the surrounding
hospitals to refer patients with serious injuries to it for expert care) is seeking additional funds from next year’s health budget for more equipment and staff. A local politician (who would rather spend such money on a new hospital named after his father) criticizes this request for additional resources by claming that Regional Trauma Centers do not, in fact, save lives, and he submits the following data to back up his claim.
You are asked for your opinion on these data. How should you respond?
surrounding hospitals regional trauma center
# of cases # of deaths
# of cases # of deaths
Total 7,266 458 3,354 212
Case-fatality rate 458/7,266 = 6.3% 212/3,354 = 6.3%
Secondary Data Exercise #1
You, being expert in possible sources of confounding in secondary data, say the data are incomplete as presented. You propose re-analysis, taking into account the severity of the trauma in all treated cases.
By examining the data stratified by severity, the value of the regional trauma center becomes clear.
Severity of Trauma Surrounding Hospitals Regional Trauma Center
# cases # deaths fatality rate
# cases # deaths
fatality rate
Mild 3,734 37 1.0% 687 3 0.4%
Moderate 1,887 94 5.0% 1,238 37 3.0%
Severe 1,645 327 19.9% 1,429 172 12.0%
Total 7,266 458 6.3% 3,354 212 6.3%
Data Quality
• If no reliable (accurate and adequate) data are available, questions about risk adjustment are moot
• Inconsistent practices in assigning standard ICD9 codes & names to diseases exist—but this has improved over time (Do you know who assigns the codes?) http://www.eicd.com/
• Lack of specificity of ICD9 system in some diagnostic areas, especially with regard to severity
Administrative Data Limitations
Need patient-specific identifiers to link episodes Need multi-year data when outcomes are infrequent Limited generalizability if restricted by type of
institution or hospital, by type of payor, or by location/region
May lack important clinical variables known to be related to outcomes (especially clinical tests or qualitative evaluations of severity)
