Mailings timed to patients' appointments: a controlled trial of fecal occult blood test cards

BACKGROUND: Fecal occult blood testing (FOBT) programs cost-effectively reduce colon cancer mortality. To improve the rate of colon cancer screening with FOBT, we tested the effect of mailing FOBT cards timed to appointments on the rates of completion of FOBT. DESIGN: Controlled trial. SETTING/PARTICIPANTS: A total of 119 patients with primary care appointments scheduled in May or June 2000 for an urban, public hospital clinic that serves predominantly low-income, African Americans with chronic diseases. The patients in the study were selected by linking a quality improvement registry, the appointment system database, and an FOBT database to generate a list of clinic patients who had not completed an FOBT in the preceding year. INTERVENTION: Subjects were assigned to either a system of mailing FOBT cards and reminders 2 weeks prior to a scheduled appointment or usual care. MAIN OUTCOME MEASURES: The primary outcomes were the rate of screening at the index appointment and during the year beginning with the date of the index appointment. RESULTS: The rate of return of the FOBT cards during the year beginning with the index appointment was 40.7% for the intervention group compared to 5% for the usual care group (odds ratio [OR]=13.0, p <0.001). The difference was accounted for largely by increases in screening at the index appointment (35.6% compared to 3.3%, OR=16.0, p <0.001). CONCLUSIONS: Using computer databases to generate a list of patients due for FOBT and then mailing FOBT cards timed to a scheduled appointment significantly increased the rate of colon cancer screening. This may be an efficient approach to increasing colon cancer screening with FOBT.     

Factors associated with colon cancer screening: the role of patient factors and physician counseling

BACKGROUND: The prevalence of colon cancer screening is nationally low. The relative contribution of patient factors and physician counseling patterns to the low prevalence of screening is unclear. METHODS: We used multivariable analysis to examine the prevalence of colon cancer screening nationally and the reasons for this low prevalence using data from the 2000 National Health Interview Survey, a nationally generalizable survey of US households. RESULTS: Among 11,427 respondents to the Cancer Control Supplement, 16% reported annual fecal occult blood testing (FOBT) and 29% reported having undergone a sigmoidoscopy in the last 5 years or a colonoscopy in the last 10 years. After adjusting for age, sex, body mass index (BMI), healthcare access, and region of the country, Hispanics were less likely to undergo FOBT [OR 0.7 (95% CI 0.6-0.9)] and sigmoidoscopy or colonoscopy [OR 0.8 (95% CI 0.7-0.9)] compared to Whites. Respondents with lower education levels were also less likely to undergo screening. These factors were not associated with being less adherent to physician recommendations for screening. Nevertheless, non-Whites and those less educated were less likely to receive counseling from their health provider about colon cancer screening. Among respondents who did not undergo FOBT, 64% were unaware they needed the test; only 2% cited pain and discomfort as a deterrent, but 94% were not counseled by their physician about the test. Among those who did not undergo sigmoidoscopy or colonoscopy, 72% were unaware that they needed the test and only 1% was deterred by pain and discomfort; 92% were not counseled by their physician. CONCLUSION: The low prevalence of screening for colorectal cancer appears to be due to lack of awareness and inadequate provider counseling rather than poor patient acceptance for screening. Systematic counseling about colorectal cancer screening will likely improve screening rates and reduce disparities by race/ethnicity and education.     

Predictors of cancer screening among low-income primary care patients

Although population-based studies report lower rates of cancer screening among racial/ethnic minorities than among Whites in the U.S., few studies have examined predictors of screening among low-income Hispanic, Black, and Chinese primary care patients. We examined utilization of mammography, Pap smear, digital rectal examination, fecal occult blood testing, sigmoidoscopy/colonoscopy, and prostate-specific antigen testing in 833 patients from 2 community health centers in New York City, ascertaining relationships between use of screening and race/ethnicity, income, education, years in the U.S., insurance, cancer risk perception, family disease history, and physician recommendation. Despite similar access to primary care, Hispanics and Blacks reported higher utilization rates of all screening tests than Chinese (p<.01). Physician recommendation and more years in the U.S. were associated with greater use of all screening services (p<.001), with physician recommendation most strongly associated with screening. Interventions to enhance screening by at-risk groups should emphasize both physician recommendation and culturally-sensitive patient education.     

Utilization of colorectal cancer screening tests: a 1997 survey of Massachusetts internists.

BACKGROUND: Physician noncompliance with screening recommendations has been a major barrier to effective colorectal cancer control. The overall objectives of this study were to assess the current attitudes and screening behavior of primary care physicians in light of new efficacy data, revised guidelines, improved technology, and more widespread insurance coverage. METHODS: Questionnaires inquiring about knowledge, beliefs, and practice patterns related to colorectal cancer screening were mailed in mid-1997 to 700 randomly selected Massachusetts internists. RESULTS: The overall response rate was 63%. Nearly 60% of respondents reported an increase in screening behavior during the past 5 years. Most (80%) were aware of at least one set of screening guidelines and 90% reported utilizing one or more recommended screening strategies. Fecal occult blood testing (FOBT), alone (47%) or in combination with flexible sigmoidoscopy (50%), was the preferred strategy for most respondents. Colonoscopy was rarely utilized (5%) despite high perceived effectiveness. Concern about patient compliance was a significant determinant of FOBT utilization, whereas perceived effectiveness, concerns about time or efficacy data, prior procedural training, date of licensure, and use of instructional materials were independent determinants of sigmoidoscopy utilization. CONCLUSION: Massachusetts' internists report high rates of utilization of select colorectal cancer screening strategies. Future studies must validate self-reported compliance and explore barriers to screening colonoscopy.     

Predictors of fecal occult blood test (FOBT) completion among low-income adults

BACKGROUND: Fecal occult blood testing (FOBT) can reduce colorectal cancer (CRC) mortality. Unfortunately, CRC screening is underutilized. Sociocultural mediators of FOBT adherence have not been extensively studied in lower income, minority populations. This study prospectively studied FOBT return in a low-income, multiethnic population. METHODS: Participants (N = 298), aged > or =40 years, were surveyed and given FOBT kits with instructions. Those not returning kits within 30 days received a reminder telephone call. Bivariate and multivariate analyses assessed predictors of FOBT card return at 90 days. RESULTS: Participants (median age = 48) were predominately African American (69%), without private insurance (88%), and of low income. The largest group of participants preferred FOBT alone (46%), followed by whatever my doctor recommends (19%), endoscopy + annual FOBT (16%), endoscopy alone (14%), and no screening (5%). In multivariate analyses, FOBT return was predicted by age (OR = 1.05) and lack of reported FOBT barriers (OR = 3.81). Among those > or =50 and not up-to-date with screening, FOBT return was predicted by cancer fatalism (OR = 0.83). FOBT barriers were associated with age (OR = 0.96), less than high school education (OR = 2.05), and less physician trust (OR = 2.12). Endoscopy barriers were associated with age (OR = 0.93), less physician trust (OR = 1.95), and female gender (OR = 3.45). CONCLUSIONS: Younger individuals and those with less education, less trust in health care providers, and more fatalistic beliefs are at risk for CRC screening non-adherence. Strategies addressing common misconceptions should improve CRC screening rates in low-income, multiethnic populations.     

Feasibility of sigmoidoscopic screening for bowel cancer in a primary care setting

Sigmoidoscopic screening for bowel cancer is controversial because of its debatable efficacy, lack of patient and physician acceptance of the procedure, and uncertainty about its practicality with the large numbers of patients in primary care settings. This study addressed patient acceptance and practicality. During an 18-month period, 75 percent of all patients aged 50 years and greater who were seen for health maintenance accepted sigmoidoscopy. The procedure was integrated into office routines without disrupting other patient care. While compliance with fecal occult blood testing was high (88 percent), sensitivity of this test for neoplastic polyps within reach of the proctosigmoidoscope was low (11 percent). These results suggest that acceptance of sigmoidoscopy by patients seen in family physicians' offices could be greater than has been anticipated.     

Barriers and Facilitators of Colon Cancer Screening Among Patients At Faith-Based Neighborhood Health Centers

We determined the barriers to and facilitators of colorectal cancer (CRC) screening among two faith-based, inner city neighborhood health centers in Southwestern Pennsylvania. Data from a random sample of patients 50 years and older (n=375) were used to estimate logistic regression equations to compare and contrast the predictors of four different CRC screening protocols: (1) fecal occult blood test (FOBT) 2 years ago, (2) colonoscopy 10 years ago, (3) lower endoscopy (colonoscopy or sigmoidoscopy) 10 years ago, and (4) any of these screening measures. Racial differences (between African Americans or Caucasians) in type of colon cancer screening were not found. Controlling for covariates, logistic regression equations showed that a physicians support of colon cancer screening was positively associated with the receipt of colonoscopy (OR: 19.47, 95 CI: 5.45–69.54), lower endoscopy (OR: 10.96, 95 CI: 3.77–31.88) and any colon cancer screening (OR: 10.12, 95 CI: 3.36–30.46). Patients who see their physicians more frequently were also more likely to be screened for CRC. Unlike other studies, the faith-based environment in which these patients are treated may explain the lack of racial disparity specific to our measures of CRC screening.     

Cancer screening estimates for U.S. metropolitan areas

OBJECTIVES: To provide estimates of breast, cervical, and colorectal cancer screening for metropolitan areas in the United States. METHODS: Behavioral Risk Factor Surveillance System (BRFSS) data from 1997 to 1999 were reweighted and analyzed for 69 U.S. metropolitan areas for the receipt of a Papanicolaou (Pap) test (ages > or =18 years); mammography (ages > or =40 years); fecal occult blood testing and sigmoidoscopy (ages > or =50 years). Stratified analyses by demographics were performed for 25 metropolitan areas with populations of > or =1.5 million. RESULTS: Metropolitan estimates ranged from 64.6% to 82.0% for mammography and from 77.2% to 91.7% for Pap tests. There was much greater variability in estimates for colorectal cancer screening, with a 3.6-fold difference in the range of estimates for fecal occult blood testing (9.9% to 35.2%) and a 2.5-fold difference for sigmoidoscopy (17.3% to 43.3%). In the 25 largest areas, prevalence of cancer screening was generally lower for persons with a high school education or less and for those without health insurance. Compared with women aged 50 to 64 years, mammography estimates were lower for women aged 40 to 49 years in 13 of the 25 metropolitan areas. Pap testing was less common among women aged > or =65 years, and colorectal cancer screening was less common for persons aged 50 to 64 years. CONCLUSIONS: Estimates of cancer screening varied substantially across metropolitan areas. Increased efforts to improve cancer screening are needed in many urban areas, especially for colorectal cancer screening. The BRFSS is a useful, inexpensive, and timely resource for providing metropolitan-area cancer screening estimates and may be used in the future to guide local or county-level screening efforts.     

Use of colorectal cancer tests--United States, 2002, 2004, and 2006

Colorectal cancer is the second-leading cause of cancer-related deaths in the United States among cancers that affect both men and women. The U.S. Preventive Task Force and other national organizations recommend that persons aged > or =50 years at average risk be screened for colorectal cancer using one or more of the following methods: fecal occult blood testing (FOBT) every year, sigmoidoscopy or double-contrast barium enema every 5 years, or colonoscopy every 10 years. To estimate rates of use of colorectal cancer tests and to evaluate changes in test use, CDC compared data from the 2002, 2004, and 2006 Behavioral Risk Factor Surveillance System (BRFSS) surveys. This report describes the results of that comparison, which indicated that the proportion of respondents aged > or =50 years reporting use of FOBT and/or sigmoidoscopy or colonoscopy increased overall from 2002 to 2006; however, certain populations, such as racial/ethnic minorities and those who reported no health insurance coverage, had lower prevalence of testing. Specific measures to increase colorectal cancer screening and address disparities in screening are needed.     

Flexible sigmoidoscopy in asymptomatic patients with negative fecal occult blood tests.

BACKGROUND. Although the American Cancer Society and others have established guidelines for colorectal cancer screening, questions of who and how to screen still exist. METHODS. A 60-cm flexible sigmoidoscopy was performed on 1000 asymptomatic patients, 45 years of age or older, with negative fecal occult blood tests, who presented for routine physical examinations. Patients with clinically significant lesions were referred for colonoscopy. The proportion of lesions that would not have been found if the 24-cm rigid or the 30-cm flexible sigmoidoscope had been used was identified. RESULTS. Using the 60-cm flexible sigmoidoscope, lesions were found in 3.6% of the patients. Eighty percent of the significant lesions were beyond the reach of the 24-cm rigid sigmoidoscope and 37% were beyond the reach of the 30-cm sigmoidoscope. Thirty-six patients with lesions were referred for colonoscopy; additional lesions were found in 14%. A total of 62 lesions were discovered, including tubular adenomas, villous adenomas, tubular villous adenomas (23 of the adenomas with atypia), and one adenocarcinoma. The highest percentage of lesions discovered were in the sigmoid colon and the second highest percentage were in the ascending colon. CONCLUSIONS. The 60-cm flexible sigmoidoscope was able to detect more lesions than either the 24-cm or 30-cm sigmoidoscope when used in asymptomatic patients, 45 years of age and over, with negative fecal occult blood tests. When significant lesions are discovered by sigmoidoscopy, colonoscopy should be performed.     

Screening for bowel cancer among NSW adults with varying levels of risk: a community survey

Objective: To estimate the extent and modality of screening for colorectal cancer in NSW among community-dwelling adults aged over 40 with varying degrees of familial risk.
Design: Cross-sectional telephone survey with participants randomly selected from the electronic NSW telephone directory.
Main results: 5.7% of people at average risk aged 40–49 report having had at least one faecal occult blood test (FOBT) in the previous five years, compared with 18.4% of those at average risk aged 50 and over. Of those at above-average risk (by age and familial risk), 7.9% reported that they had had an FOBT in the previous five years.
Around 5% of respondents aged 40–49 and 10% of those aged 50+ reported having had a colonoscopy/sigmoidoscopy for screening within the previous five years, compared with 30% of those at above-average risk. People with medical insurance were more likely to have undergone a screening test (either FOBT or sigmoidoscopy/colonoscopy), than those without insurance (PR=1.30; 95% CI 1.02–1.67). Compared with those employed full time, those who were retired (PR=1.45 95% CI 1.01 -2.09) and those who reported home duties (PR=1.54 95% CI 1.01 -2.36) were slightly, but significantly more likely to report having had a test. As perception of personal risk for colorectal cancer increased, so did the likelihood of having had a screening test within the previous five years (PR=1.19; 95% CI 1.05–1.35).
Conclusion: We have reported important baseline data with which to compare the progress of both pilot screening programs and more widespread implementation of colorectal screening in Australia. In particular, we have highlighted the need for greater participation in screening for those at increased familial risk.

Program to improve colorectal cancer screening in a low-income, racially diverse population: a randomized controlled trial

PURPOSE More effective strategies are needed to improve rates of colorectal cancer screening, particularly among the poor, racial and ethnic minorities, and individuals with limited English proficiency. We examined whether the direct mailing of fecal occult blood testing (FOBT) kits to patients overdue for such screening is an effective way to improve screening in this population. METHODS All adults aged 50 to 80 years who did not have documentation of being up to date with colorectal cancer screening as of December 31, 2009, and who had had at least 2 visits to the community health center in the prior 18 months were randomized to the outreach intervention or usual care. Patients in the outreach group were mailed a colorectal cancer fact sheet and FOBT kit. Patients in the usual care group could be referred for screening during usual clinician visits. The primary outcome was completion of colorectal cancer screening (by FOBT, sigmoidoscopy, or colonoscopy) 4 months after initiation of the outreach protocol. Outcome measures were compared using the Fisher exact test. RESULTS Analyses were based on 104 patients assigned to the outreach intervention and 98 patients assigned to usual care. In all, 30% of patients in the outreach group completed colorectal cancer screening during the study period, compared with 5% of patients in the usual care group (P <.001). Nearly all of the screenings were by FOBT. The groups did not differ significantly with respect to the percentage of patients making a clinician visit or the percentage for whom a clinician placed an order for a screening test. CONCLUSIONS The mailing of FOBT kits directly to patients was efficacious for promoting colorectal cancer screening among a population with high levels of poverty, limited English proficiency, and racial and ethnic diversity. Non-visit-based outreach to patients may be an important strategy to address suboptimal rates of colorectal cancer screening among populations most at risk for not being screened.     

A randomized controlled trial to increase cancer screening among attendees of community health centers

BACKGROUND: We assessed the efficacy of the Cancer Screening Office Systems (Cancer SOS), an intervention designed to increase cancer screening in primary care settings serving disadvantaged populations. METHODS: Eight primary care clinics participating in a county-funded health insurance plan in Hillsborough County, Fla, agreed to take part in a cluster-randomized experimental trial. The Cancer SOS had 2 components: a cancer-screening checklist with chart stickers that indicated whether specific cancer-screening tests were due, ordered, or completed; and a division of office responsibilities to achieve high screening rates. Established patients were eligible if they were between the ages of 50 and 75 years and had no contraindication for screening. Data abstracted from charts of independent samples collected at baseline (n = 1,196) and at a 12-month follow-up (n = 1,237) was used to assess whether the patient was up-to-date on one or more of the following cancer-screening tests: mammogram, Papanicolaou (Pap) smear, or fecal occult blood testing (FOBT). RESULTS: In multivariate analysis that controlled for baseline screening rates, secular trends, and other patient and clinic characteristics, the intervention increased the odds of mammograms (odds ratio [OR] = 1.62, 95% confidence interval [CI], 1.07-9.78, P = .023) and fecal occult blood tests (OR = 2.5, 95% CI, 1.65-4.0, P <.0001) with a trend toward greater use of Pap smears (OR = 1.57, 95% CI, 0.92-2.64, P = .096). CONCLUSIONS: The Cancer SOS intervention significantly increased rates of cancer screening among primary care clinics serving disadvantaged populations. The Cancer SOS intervention is one option for providers or policy makers who wish to address cancer related health disparities.     

Factors associated with colorectal cancer screening among the US urban Japanese population

OBJECTIVES: The author examined the prevalence and predictors of colorectal cancer screening among the urban Japanese population of the United States. METHODS: A sample of Japanese residents of major US metropolitan areas completed a self-administered mailed survey. RESULTS: Physician recommendation, acculturation, and perceived psychological costs were consistent predictors of screening for colorectal cancer. Gender and marital status were related to screening via fecal occult blood testing; age, susceptibility, and health insurance were related to sigmoidoscopy/colonoscopy screening. CONCLUSIONS: Colorectal cancer screening among the urban Japanese population could be increased with interventions seeking to promote physician recommendations for screening, alleviate perceived psychological costs among patients, and improve physician-patient communication.     

Primary Care,Economic Barriers to Health Care,and Use of Colorectal Cancer Screening Tests Among Medicare Enrollees Over Time

PURPOSE Colorectal cancer (CRC) screening remains underutilized. The objective of this study was to examine the impact of primary care and economic barriers to health care on CRC testing relative to the 2001 Medicare expansion of screening coverage.METHODS Medicare Current Beneficiary Survey data were use to study community-dwelling enrollees aged 65 to 80 years, free of renal disease and CRC, and who participated in the survey in 2000 (n = 8,330), 2003 (n = 7,889), or 2005 (n = 7,614). Three outcomes were examined: colonoscopy/sigmoidoscopy within 5 years (recent endoscopy), endoscopy more than 5 years previously, and fecal occult blood test (FOBT) within 2 years.RESULTS Endoscopy use increased and FOBT use decreased during the 6-year period, with no significant independent differences between those receiving care from primary care physicians and those receiving care from other physicians. Beneficiaries without a usual place of health care were the least likely to undergo CRC testing, and that gap widened with time: adjusted odds ratio (AOR) = 0.27 (95% confidence interval [CI], 0.19–0.39) for FOBT, and AOR = 0.35 (95% CI, 0.27–0.46) for endoscopy in 2000 compared with AOR = 0.18 (95% CI, 0.11–0.30) for FOBT and AOR = 0.22 (95% CI, 0.17–0.30) for endoscopy in 2005. Disparities in use of recent endoscopy by type of health insurance coverage in both 2000 and 2005 were greater for enrollees with a high school education or higher than they were for less-educated enrollees. There were no statistically significant differences by delayed care due to cost after adjustment for health insurance.CONCLUSION Despite expanding coverage for screening, complex CRC screening disparities persisted based on differences in the usual place and cost of health care, type of health insurance coverage, and level of education.     

Cancer Screening Practices of Asian American Physicians in New York City

Cancer screening rates are lower among Asian Americans than the general USA population. While prior studies examined characteristics of Asian American patients as predictors of cancer screening, few investigated their health care providers. Asian American primary care physicians practicing in New York City were surveyed by questionnaire regarding their demographics, practice characteristics, and cancer screening of their Asian American patients. Of the 117 eligible respondents, 96% recommended mammograms to their Asian patients 50+ years of age and 70% to patients 40–49-year-old. Only 30% of respondents use both age and onset of sexual activity to determine when to recommend Pap smears. For colorectal cancer screening, the rates of performing fecal occult blood testing or recommending colonoscopy or sigmoidoscopy were 77% and 74%. About 70% recommend screening for hepatitis B. Gender and ethnicity of the physician were found to be significant predictors for cancer screening practice.     

Colorectal cancer screening among Mexican Americans at a community clinic

BACKGROUND: Mexican Americans tend to under-utilize colorectal cancer (CRC) prevention. Yet little is known about sociocultural factors associated with CRC screening. This study assessed predictors of three primary CRC tests among low-income Mexican Americans. METHODS: From May to December 2003, an availability sample of 287 patients, aged 50 to 89 years, who presented for routine care at a community health center near the U.S.-Mexico border completed surveys on CRC knowledge, awareness, attitudes toward screening, logistic barriers, perceptions of health, locus of control, acculturation, whether their doctor discussed CRC screening, and sociodemographics. Participants also reported whether they had ever had a fecal occult blood test, flexible sigmoidoscopy, or colonoscopy. Logistic regression identified predictors of having had these tests. RESULTS: Overall, 41% reported having ever had any of the three tests; 34.1% had a fecal occult blood test; 6.6%, flexible sigmoidoscopy; and 11.8%, colonoscopy. Few respondents reported any clear knowledge about CRC, and only 41% said their doctor had ever discussed screening with them. Yet "doctor discussed screening" was the only consistent screening predictor across tests. CRC knowledge (p=0.006) and insurance coverage (p=0.009) predicted having had a flexible sigmoidoscopy. Perceptions of general poor health also predicted having had a flexible sigmoidoscopy or a colonoscopy (p=0.04). Being employed marginally predicted whether patient had ever had any of the three tests (p=0.05). CONCLUSIONS: Results show that even those in contact with community medical services exhibit low CRC screening rates. They further suggest that interventions focused on clinical settings are an important first step toward CRC prevention in this community.     

Colorectal cancer-screening tests and associated health behaviors.

BACKGROUND: Studies have shown that screening reduces colorectal cancer mortality. We analyzed national survey data to determine rates of use of fecal occult blood testing (FOBT) and sigmoidoscopy, and to determine if these rates differ by demographic factors and other health behaviors. METHODS: A total of 52,754 respondents aged >or=50 years were questioned in the 1997 Behavioral Risk Factor Surveillance System (BRFSS) survey (a random-digit-dialing telephone survey of the non-institutionalized U.S. population) about their use of FOBT and sigmoidoscopy. RESULTS: The age-adjusted proportion of respondents who reported having had a colorectal cancer screening test during the recommended time interval (past year for FOBT and past 5 years for sigmoidoscopy) was 19.8% for FOBT, 30.5% for sigmoidoscopy, and 41.1% for either FOBT or sigmoidoscopy. Rates of use of colorectal cancer screening tests were higher for those who had other screening tests (mammography, Papanicolaou smear, and cholesterol check). There were also differences in rates of use of colorectal cancer screening tests according to other health behaviors (smoking, seat belt use, fruit and vegetable intake, and physical activity) and several demographic factors. However, none of the subgroups that we examined reported a rate of FOBT use above 29% within the past year or a rate of sigmoidoscopy use above 41% within the past 5 years. CONCLUSIONS: While rates of use of FOBT and sigmoidoscopy were higher among people who practiced other healthy behaviors, rates of use were still quite low in all subgroups. There is a need for increased awareness of the importance of colorectal cancer screening.     

Impact of a physician-oriented intervention on follow-up in colorectal cancer screening

BACKGROUND: Complete diagnostic evaluation or CDE (i.e., colonoscopy or combined flexible sigmoidoscopy plus barium enema X-ray) is often not performed for persons with an abnormal screening fecal occult blood test (FOBT+) result. METHOD: This study evaluated the impact of a reminder-feedback and educational outreach intervention on primary care practice CDE recommendation and performance rates. Four hundred seventy primary care physicians (PCPs) in 318 practices participated in the study. Patients were mailed an FOBT kit annually as part of a screening program. Practices were randomly assigned to a Control Group (N = 198) or an Intervention Group (N = 120). During an 18-month pre-randomization period and a 9-month post-randomization period, 2992 screening FOBT+ patients were identified. Intervention practices received the screening program and the intervention. Control practices received only the screening program. Study outcomes were baseline-adjusted CDE recommendation and performance rates. RESULTS: At baseline, about two-thirds of FOBT+ patients received a CDE recommendation, and about half had a CDE performed. At endpoint, CDE recommendation and performance rates were both significantly higher for the Intervention as compared to the Control practices (OR = 2.28; 95% CI: 1.37, 3.78, and OR = 1.63; 95% CI: 1.06, 2.50, respectively). CONCLUSIONS: The reminder-feedback plus educational outreach intervention significantly increased CDE recommendation and performance.
