Supported by • Department of Veterans’ Affairs (VA) • HSR&D: Health Services Research and Development • QUERI: Quality Enhancement Research Initiative, Colorectal Cancer
Objectives • Determine sources of CRC screening variation • Determine role of practice and clinical leader autonomy
Colorectal Cancer (CRC) Screening Modalities Chart documentation of: • FOBT in last year, • Flexible sigmoidoscopy in last 5 years or • Colonoscopy in last 10 years
CRC Screening Rates: CDC 2001 • #2 cause of cancer deaths (57,000) • Early detection reduces mortality • National average: 53% • Variation by State: 42--65%
CRC Screening at the VA Department of Veterans’ Affairs • Mean 60% • Varies by • Region: 55% to 62% • Facility: 25% to 88% • Lowest preventive measure at VA medical centers
Facility Population • All VA primary-care sites • Serving >4,000 primary care patients • Delivering >20,000 primary care visits • N=235 • Response 219 sites (93%)
Data Sources • CRC screening rates from the • External Peer Review Program of • 71,000 charts (2001) • Organizational structures and processes from the • Primary Care Practices Survey (2000)
Conclusions • Primary care practice leader autonomy was associated with higher CRC screening • No other measure altered this relationship: academic affiliation, quality improvement, or size
Limitations • Facilities within one health system • 1999-2000 data in changing times • Captures perceptions not actual activity • Leader characteristics are unmeasured
Implications/Potential Impact: • Increasing Clinical Leader Autonomy over practice arrangements may • enhance receipt of preventive services • result in earlier detection of cancer • lower mortality • Value of Autonomy relative to needs for consistency needs further exploration
