Colorectal cancer in Kentucky (SEER)

Appalachian Kentucky Compared with the rest of the United States, Appalachia is  medically underserved  economically distressed  disproportionately burdened with cancer

Education & Employment Education (%) Perry Co. KY High School or higher Bachelor’s or higher Unemployment (%) Poverty (%)

To increase colorectal cancer screening provided by primary care practices in Appalachian Kentucky Project Goal

Methods Phase 1:Formative Research Phase 2:Intervention Trial

Phase I: Formative Research  Provider survey to establish contact with practices and identify general characteristics  Focus groups to obtain qualitative information and fill gaps in survey data

Phase II: Intervention Trial Participants: Primary care practices in Appalachian Kentucky  Family Medicine  General Internal Medicine  General Practice Outcome: Increase Screening (FOBT, FS, DCBE, Colonoscopy )

Academic Detailing Intervention 1.Academic detailing involves providing education where physicians are instructed through personal contact with an individual or group focused on a specific topic 2.Well-known as a method for pharmaceutical sales, this approach has been found to be a novel and effective way to reach busy physicians to provide medical education.

Objectives guiding Implementation Implement an educational intervention through academic detailing Evaluate the effectiveness of the intervention at 6 and 18 month post intervention data collection. 6 – month data to assess efficacy 18- month data to assess sustainability

Intervention Planning Need for partnerships Identification of primary care practices Desire for a community-based approach to intervention delivery Project management issues Travel and logistics Communication with practices Area Health Education Centers

Why Area Health Education Centers? Regional agencies in Kentucky Provide structure for continuing medical education Provide for opportunities for health professional training outside academic institutions They have capacity for outreach to rural health care providers Education is key to their mission Research participation is a new activity for them

Study Areas – Three AHEC Regions

Recruitment and Baseline Assessment RandomizationIntervention 6-Month Post- Intervention Data Collection 18-Month Post Intervention Data Collection 66 Practices Group 1 (n=33) InterventionOO Randomize Group 2 (n=33) DelayedOO Research Design

Procedures 1.An academic detailer in each AHEC region recruited primary care practices. 2.A physician in each practice completed a provider interview. 3.The academic detailer delivered the intervention – the intervention modules focused on Efficacy of colorectal cancer screening Reimbursement Patient counseling Practice management. 4.Project staff conducted medical record reviews in each practice

Evaluation Plan – Process and Q/C  Process  Monitoring data collection and intervention delivery  Quality control  Post intervention assessment of veracity of reports

Evaluation Plan - Outcomes  Outcomes  Quantitative – Proportion of patients ‘screened’ in practices  Qualitative – Key informant interviews to assess intervention and project experience  Health care providers  Office staff  Intervention staff

Screening Recommended and Completed by Study Group, BASELINE 25

Findings – To date Screening rates are low. Colonoscopy appears to be the screening test that is recommended most commonly in this population. Rates for fecal occult blood testing are low which may indicate a lack of enthusiasm for this method. Rates for flexible sigmoidoscopy are so small as to be negligible, suggesting that primary health care providers have largely ceased providing this service.

Next Steps Complete delayed group intervention delivery Complete post-intervention data collection Analyze data and investigate stopping rule Schedule 18 month follow-up data collection Develop application to fund dissemination study

Dissemination study (Effectiveness) Tentative Research Questions 1. Can an academic detailing intervention designed to increase colorectal cancer screening in rural primary care practices be disseminated through the AHEC system? 2.. Are there factors that facilitate or inhibit the diffusion of innovation process through the AHEC system?

Screening for Colorectal Cancer is Effective

Colorectal Cancer Screening Evidence Fecal Occult Blood Test (FOBT) 33% mortality reduction, 20% incidence reduction (annual testing, three cards at home) Sigmoidoscopy 59% mortality reduction within reach of scope Colonoscopy 40-60% incidence reduction Double Contrast Barium Enema (DCBE) Still being evaluated as screening tool

Everyone 50 years and older should receive regular screening for colorectal cancer High risk individuals may need to begin screening earlier

Colorectal Cancer Screening Guidelines FOBT yearly Sigmoidoscopy 5 years Colonoscopy 10 years DCBE 5 years

Summary  Colorectal cancer is the second leading cause of cancer-related deaths in the US and Kentucky  Colorectal cancer incidence rates tend to be higher in eastern Kentucky  Current screening methods are FOBT, sigmoidoscopy, colonoscopy, and DCBE  All asymptomatic patients age 50 and over should be referred for screening FOBT = annually; Sigmoidoscopy = 5 years; Colonoscopy = 10 years; DCBE = 5 years
