Surveillance Databases: Clinical Case Registry (CCR), NSQUIP, and VACS
Amy C. Justice 8/17/2006
2
Outline What is a surveillance database?
What are the strengths and weaknesses of VHA for surveillance? What does it take to develop and maintain a surveillance database? How can you work with a surveillance database to conduct your own research? 8/17/2006
3
Surveillance Surveillance (Concise Oxford Dictionary)
“Supervision, close observation, especially of a suspected person.” 8/17/2006
4
What Do We Want to Monitor?
Infections Epidemics: HIV, HCV, “bird flu” Hospital infections (C. difficile; post op; MRSA) Homeland security: plague, etc. Cancer Injuries Quality of care/ patient safety Infant mortality (cause of death) Pharmacoepidemiology Treatment benefit in average patients Treatment harm in average patients 8/17/2006
5
Approaches to Health Surveillance
Population level Gold standard Difficult and expensive Clinical population (mandated for some) Sentinel clinical sites (common) EMR based health system (emerging) How do those in care differ from the whole? 8/17/2006
6
Epidemiology Vs. Clinical Epidemiology
How do folk who come in for care differ from those who don’t? They are motivated to seek care Prevalence/ severity/ rate of progression They think care will do them some good They have access to care Economic/Education/Other Resources Can make time to come in Understand how to use care 8/17/2006

Veterans Vs. Veterans in Care
Veterans are different from the general population More likely to be men Health and literacy screening at enlistment Veterans in care in VHA are different from other veterans 15% of veterans use VHA Poorer, urban, more likely to be male Sicker, older, more comorbidity Less likely to have alternative health insurance 8/17/2006

10
Socioeconomic Status Education:
In 1999, significant differences existed between male veterans and nonveterans in their highest level of education attained: 12% of male veterans had not graduated from high school compared to 18% for male nonveterans. A higher proportion of male veterans (65%) than male nonveterans (56%) had at least a high school education or had completed 1 to 3 years of college. Male nonveterans are more likely than male veterans to have completed 4 or more years of college (26% vs. 23%). Source: Current Population Survey, March 1999 8/17/2006 5

Socioeconomic Status Education (Cont’d):
About the same percentage of male veterans as male nonveterans had at least some some college (52% vs. 51%). However, a higher percentage of male veterans “40-54” (mostly Vietnam era) than male nonveterans of that age had at least some college (61% vs. 57%). Also, a higher percentage of male veterans age “20-39” (post-Vietnam and Gulf War era) than similarly aged male nonveterans had at least some college (54% vs. 52%).

14
Socioeconomic Status Personal Income:
In general, personal income in 1999 was higher for male veterans than male nonveterans due, in part, to differences in their age and to possible differences in job skills and training. The median income of $28,800 for male veterans was 9% higher than the median of $26,400 for their male nonveteran counterparts. The median income of $37,100 for male veterans age “40 -54” (Vietnam era) was the highest, and the median of $14,600 for male nonveterans age “65 or over” was the lowest.

16
Socioeconomic Status Unemployment:
In 1999, the annual average (of the monthly data for January through December 1999) unemployment rate of 3.2% among veterans was lower than the 3.7% rate for their nonveteran counterparts. Similarly, the 3.1% unemployment rate among male veterans was lower than the 3.6% rate among male nonveterans. However, the 4.6% unemployment rate for female veterans was higher than the 3.7% rate for their female nonveteran counterparts. Source: Current Population Survey data for CY 1999 8/17/2006 11

18
Socioeconomic Status Health Insurance:
VA users of inpatient and outpatient care have greater health insurance coverage problems than veterans in general. About 9% of all veterans, most of whom are male, were uninsured at the time of the National Survey of Veterans interview in This compares to 21% of VA users. Among veterans “under 65”, 13% were uninsured in 1993, while among VA users “under 65”, 29% were uninsured. Nearly all veterans age “65 or over” are covered by Medicare; only about 1% are not. However, among VA users age “65 or over” about 7% are uninsured. Source: 1993 National Survey of Veterans 8/17/2006 13

Socioeconomic Status Special Needs Veterans Poverty:
In March 1990, only 5.7% of all veterans were at or below the poverty level compared to 9.1% of all adult U.S. males. Most states with poverty rates above 5.7% among veterans were in the South and Northwest. Generally,states in New England and the Mid-Atlantic had the lowest veteran poverty rates.

Socioeconomic Status Special Needs Veterans (Cont’d) Incarceration:
In March 1990, about 166,000 male veterans were in prisons. This represents a rate of 636 per 100,000 veterans, half the rate of nonveteran adult males. By 1997, the rates of incarceration increased for both male veterans and nonveterans, but the rate for veterans was still about half that of nonveterans. The lower rate for veterans is explained in part by a smaller proportion of veterans in the young age groups which make up most of the prison population. Source: Decennial Census 8/17/2006 17

Socioeconomic Status Special Needs Veterans (Cont’d)
Incarceration (Cont’d): More recently, the Bureau of Justice Statistics in the Department of Justice sponsored surveys in 1996 and 1997 on inmates in state, federal, and local correctional facilities. Data on veterans were included. In 1997, 225,700 veterans, or less than 1% of all veterans, were in prisons and jails. Males made up most of the prison population. Among veterans in all correctional facilities, 99% were male compared to 89% of nonveterans in jail, 92% of nonveterans in federal prisons, and 93% of nonveterans in state prisons. Source: Bureau of Justice Statistics 8/17/2006 19
25
Socioeconomic Status Special Needs Veterans (Cont’d)
Incarceration: (Cont’d): Most veterans in state prisons, 55%, were sentenced for violent offenses, compared to 46% of nonveterans. Most veterans (51%) as well as most nonveterans (65%) in federal prisons were sentenced for drug offenses. The most frequent offenses for veterans in local jails were public order or other offenses (31%), and for nonveterans they were property offenses (27%). Age and socioeconomic differences account in part for the differences in types of offense committed by male veterans and nonveterans. Because male veterans are, on average, older and more likely to be employed before imprisonment, they are more likely to be sentenced for violent crimes and less likely for drug and property crimes than their nonveteran counterparts.

Homelessness Male Veterans and Nonveterans in Shelters 1990
Socioeconomic Status Homelessness Male Veterans and Nonveterans in Shelters 1990 Source: Decennial Census 8/17/2006
27
Socioeconomic Status Special Needs Veterans (Cont’d) Homelessness:
Hard data on the homeless population are difficult to obtain. The last Census counted 39,000 male veterans in emergency homeless shelters in March This understates the extent of the problem because many homeless do not reside in shelters. The total number of male veterans in homeless shelters was about half the number of adult male nonveterans in shelters. But the rate of residence in shelters was higher for male veterans (149 per 100,000) than for adult male nonveterans (126 per 100,000). The rates were also higher for Black veterans than for White and Hispanic veterans. Source: Decennial Census 8/17/2006 22

Socioeconomic Status Special Needs Veterans (Cont’d) Mental Illness:
The 1990 census counted 14,000 male veterans in mental hospitals compared to 50,000 adult male nonveterans. For every 100,000 male veterans in the veteran population in 1990, there were 54 male veterans in mental hospitals compared to 87 per 100,000 adult male nonveterans. Veterans under age 40 are somewhat more likely to be in mental hospitals than male nonveterans of that age; at age “40 or over”, however, male veterans are less likely than male nonveterans to be in mental hospitals.

Selected VA Programs Healthcare Enrollment (Cont’d) Current Enrollees:
As of September 27, 1999, there was a total of 4,068,965 veterans enrolled in the VA Healthcare Enrollment Program. Priority Groups 5 and 7, which include nonservice-connected veterans, account for about 59% of all enrollees. More than 80 percent of enrolled veterans belong to Priority Groups which require no copayment. Total enrollment is expected to peak in the near future.

Science 8/17/2006
52
Primary Question How can we change the care provided to those with HIV infection to efficiently improve outcomes? --“Where is the low hanging fruit?” 8/17/2006
53
Patient Outcomes in HIV in 2006
Aging Comorbid Disease, Behaviors, & NonARV Toxicity HIV HIV Treatment 8/17/2006
54
Hypothesis Observations Primary Hypothesis
HIV is now a chronic disease complicated by comorbid illness and behaviors (comorbidity). Comorbidity has a major modifiable impact on outcomes directly and by decreasing HAART benefit Primary Hypothesis We can make a substantial difference in HIV outcomes by improving the management of comorbidity 8/17/2006
55
What Do We Need? Records of all treatment (HIV and other)
VA Pharmacy Records Outside Pharmacy Records? Measures of comorbid diagnoses and behaviors Diagnoses: codes vs. full chart review vs. standardized screening Behaviors: difficult to get from medical record Outside VA? Measures of frailty Functional status Physiologic measures Measures of outcome (usual suspects) Mortality (BIRLS plus discharged “dead” plus SSN) Morbidity (symptoms, function, quality of life) Utilization (hospitalizations, clinic visits, overall costs) Outcomes outside VA? 8/17/2006
56
What Do We Want on the Patient?
Health behaviors Diet Exercise Alternative medicines Drugs, Alcohol, Cigarettes Health beliefs Readiness to change behaviors 8/17/2006
57
What Data Do We Want on Provider?
Training Experience Health care beliefs Assessment of patient 8/17/2006
58
What Can We Get on NonVA Care?
Patient report—variable accuracy Medications Hospitalizations Clinic Visits Medicare Medicaid—very difficult 8/17/2006

Resources 8/17/2006
60
Sensitivity and Specificity I
Routine data is specific, but not sensitive e.g., if a chart note says the patient has pneumonia, they likely do. However, not all pneumonias are identified. ICD-9 codes can be made more specific if you require 2 outpatient codes This may imply that those with more severe disease are more likely to be identified An issue if you want to identify prevalence or incidence Not so much if you want to compare two groups with the same source of data 8/17/2006
61
Sensitivity and Specificity II
In comparative analyses Major impact may only be power Need to consider possibility of bias Look at Tables 2 and 4: Justice et al, Medical Disease and Alcohol Use Among Veterans with HIV infection: A Comparison of Disease Measurement Strategies Medical Care 2006;44:S52-S60 8/17/2006
62
Money Major constraint—don’t try to do more than your budget allows
Build up from foundation of “smaller” study Size refers to budget rather than numbers Can be small with respect to depth of data or number of subjects 8/17/2006
63
Time If your study requires patient contact, allow a lot more time
IRB reviews at each site Hiring staff Training staff Setting up data flow if not all electronic 8/17/2006
64
Methods 8/17/2006
65
Nature of Study Analytic design implies data design
Cross sectional (simplest analysis) Baseline to outcome Longitudinal (can get quite complex) Retrospective/Prospective may have varying effects on missing data 8/17/2006
66
8/17/2006
67
VACS Goals Describe effects of aging, medical and psychiatric comorbid disease, substance use, and drug toxicity on patient outcomes in HIV. Compare these effects among those with and without HIV infection. Identify modifiable mediators of survival; quality of life; and incidence and severity of HIV and comorbid disease. Design and implement large scale strategy trials using the EMR to improve these outcomes. 8/17/2006
68
VACS Consistent Themes
VA ID and GIM clinics All HIV positive patients seen are eligible GIM patients “matched” to HIV patients All electronic medical record (EMR) data Self completed surveys supplement EMR Permission to recontact Followed for long term outcomes 8/17/2006
