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.

Long-term Results From a Randomized Controlled Trial to Increase Cancer Screening Among Attendees of Community Health Centers

PURPOSE We assessed whether increased cancer screening rates that were observed with Cancer Screening Office Systems (Cancer SOS) could be maintained at 24 months’ follow-up, a period in which clinics were expected to be largely self-sufficient in maintaining the intervention. METHODS Eight primary care clinics serving disadvantaged populations in Hills-borough County, Fla, agreed to take part in a cluster-randomized experimental trial. Charts of independent samples of established patients aged 50 to 75 years were abstracted, with data collected at baseline (n = 1,196) and at 24 months’ follow-up (n = 1,296). Papanicolaou (Pap) smears, mammography, and fecal occult blood testing were assessed. RESULTS At 24 months of follow-up, intervention patients had received a greater number of cancer screening tests (mean 1.17 tests vs 0.94 tests, t test = 4.42, P <.0001). In multivariate analysis that controlled for baseline screening rates, secular trends, and other patient and clinic characteristics, the intervention increased the odds of mammograms slightly (odds ratio [OR]) = 1.26; 95% confidence interval [CI], 1.02–1.55; P = .03) but had no effect on fecal occult blood tests (OR = 1.17; 95% CI, 0.92–1.48; P =0.19) or Pap smears (OR = 0.88; 95% CI, 0.0.68–1.15; P = .34). CONCLUSIONS The Cancer SOS intervention had persistent, although modest, effects on screening at 24 months’ follow-up, an effect that had clearly diminished from results reported at 12 months’ follow-up. Further study is needed to develop successful intervention strategies that are either self-sustaining or that are able to produce long-term changes in screening behavior.

Colorectal Cancer Screening among a Sample of Community Health Center Attendees

To determine the rate of colorectal cancer screening in patients attending a sample of community health centers, medical records of 1,176 patients from eight community health centers were abstracted. Among the patients studied, 43.8% of patients had undergone at least one of the three colorectal screening tests (fecal occult blood test, colonoscopy, or flexible sigmoidoscopy) in the recommended interval. Colorectal screening in this community health center population was predicted by male gender, being African American, older age, having a greater number of chronic illnesses, a family history of colorectal cancer, and by having engaged in other preventive cancer screenings in the previous year. Although screening rates certainly were not optimal, they compare favorably to rates reported in national surveys for the general population. Our results add to a growing body of evidence that community health centers, despite serving disadvantaged populations, are able to deliver preventive care at rates comparable to health facilities used by the general population.

Sun Protection at Elementary Schools: A Cluster Randomized Trial

BACKGROUND Elementary schools represent both a source of childhood sun exposure and a setting for educational interventions. METHODS Sun Protection of Floridas Children was a cluster randomized trial promoting hat use at (primary outcome) and outside of schools among fourth-grade students during August 8, 2006, through May 22, 2007. Twenty-two schools were randomly assigned to the intervention (1115 students) or control group (1376 students). Intervention schools received classroom sessions targeting sun protection attitudes and social norms. Each student attending an intervention school received two free wide-brimmed hats. Hat use at school was measured by direct observation and hat use outside of school was measured by self-report. A subgroup of 378 students (178 in the intervention group and 200 in the control group) underwent serial measurements of skin pigmentation to explore potential physiological effects of the intervention. Generalized linear mixed models were used to evaluate the intervention effect by accounting for the cluster randomized trial design. All P values were two-sided and were claimed as statistically significant at a level of .05. RESULTS The percentage of students observed wearing hats at control schools remained essentially unchanged during the school year (baseline = 2%, fall = 0%, and spring = 1%) but increased statistically significantly at intervention schools (baseline = 2%, fall = 30%, and spring = 41%) (P < .001 for intervention effect comparing the change in rate of hat use over time at intervention vs control schools). Self-reported use of hats outside of school did not change statistically significantly during the study (control: baseline = 14%, fall = 14%, and spring = 11%; intervention: baseline = 24%, fall = 24%, and spring = 23%) nor did measures of skin pigmentation. CONCLUSIONS The intervention increased use of hats among fourth-grade students at school but had no effect on self-reported wide-brimmed hat use outside of school or on measures of skin pigmentation.

A Cluster Randomized Trial of Sun Protection at Elementary Schools: Results from Year 2

BACKGROUND Elementary schools are one potential venue for sun protection interventions that reduce childhood sun exposure. PURPOSE To assess Year-2 results from a cluster randomized trial promoting hat use at schools. DESIGN Block randomization was used to assign intervention/control status to participating schools. Data were collected from 2006 to 2008 and analyzed in 2007-2010. SETTING/PARTICIPANTS Of the 24 schools in the School District of Hillsborough County, Florida enrolled, 4th-graders were targeted in the first year and followed through their 5th-grade year. INTERVENTION Classroom sessions were conducted to improve sun protection knowledge, foster more positive attitudes about hat use, and change the subjective norm of wearing hats when at school. MAIN OUTCOME MEASURES Year-2 outcomes assessed included hat use at school (measured by direct observation), hat use outside of school (measured by self-report) and skin pigmentation and nevi counts (measured for a subgroup of 439 students). RESULTS The percentage of students observed wearing hats at control schools remained unchanged during the 2-year period (range 0%-2%) but increased significantly at intervention schools (2% at baseline, 41% at end of Year 1, 19% at end of Year 2; p<0.001 for intervention effect). Measures of skin pigmentation, nevi counts, and self-reported use of hats outside of school did not change during the study period. CONCLUSIONS This intervention increased use of hats at school through Year 2 but had no measurable effect on skin pigmentation or nevi. Whether school-based interventions can ultimately prevent skin cancer is uncertain.

Patients’ Perceptions of Colorectal Cancer Screening Tests and Preparatory Education in Federally Qualified Health Centers

This study explored federally qualified health center (FQHC) patients’ perceptions about colorectal cancer screening (CRCS) tests, including immunochemical fecal occult blood tests (iFOBT), as well as preferences for receiving in-clinic education about CRCS. Eight mixed gender focus groups were conducted with 53 patients. Findings centered on three thematic factors: (1) motivators and impediments to CRCS, (2) test-specific preferences and receptivity to iFOBTs, and (3) preferences for entertaining and engaging plain language materials. Results informed the development of educational priming materials to increase CRCS using iFOBT in FQHCs.

A randomized controlled trial of a multicomponent, targeted, low-literacy educational intervention compared with a nontargeted intervention to boost colorectal cancer screening with fecal immunochemical testing in community clinics

The objective of the current study was to improve colorectal cancer (CRC) screening uptake with the fecal immunochemical test (FIT). The current study investigated the differential impact of a multicomponent, targeted, low‐literacy educational intervention compared with a standard, nontargeted educational intervention.

Assessment of Elementary School Students’ Sun Protection Behaviors

Abstract:  Background/Objectives: Studies suggest that excessive sun exposure in childhood contributes to the development of skin cancer later in life. Methods: This study explores 4th grade student assessment of their sun protection behaviors. This study used baseline data collected in the Fall of 2006 for the Sun Protection for Florida’s Children (SPF) project. In brief, the SPF project is a group randomized trial to test the effectiveness of a school based intervention promoting sun protection in general, and hat use in particular, in Hillsborough County Schools, Florida. The data reported in this study were collected at baseline before any intervention activities was initiated. Results: The self‐reported use of various methods of sun protection was low. Only a small percentage of students wore long sleeves or a hat with a brim before leaving for school. In addition, few students wore a hat with a wide brim when outside but not at school. Students spent an average of 59.1 minutes per week outdoors while attending school and 35.5 minutes during peak sun exposure. Conclusion: Sun exposure at school poses a significant risk to student health and more needs to be carried out to promote the use of a wide‐brimmed hat and limiting student sun exposure.

Making it work: health care provider perspectives on strategies to increase colorectal cancer screening in federally qualified health centers.

Colorectal cancer screening (CRCS) rates are low among men and women who seek health care at federally qualified health centers (FQHCs). This study explores health care providers’ perspectives about their patient’s motivators and impediments to CRCS and receptivity to preparatory education. A mixed methods design consisting of in-depth interviews, focus groups, and a short survey is used in this study. The participants of this study are 17 health care providers practicing in FQHCs in the Tampa Bay area. Test-specific patient impediments and motivations were identified including fear of abnormal findings, importance of offering less invasive fecal occult blood tests, and need for patient-centered test-specific educational materials in clinics. Opportunities to improve provider practices were identified including providers’ reliance on patients’ report of symptoms as a cue to recommend CRCS and overemphasis of clinic-based guaiac stool tests. This study adds to the literature on CRCS test-specific motivators and impediments. Providers offered unique approaches for motivating patients to follow through with recommended CRCS and were receptive to in-clinic patient education. Findings readily inform the design of educational materials and interventions to increase CRCS in FQHCs.

Health Literacy among Medically Underserved: The Role of Demographic Factors, Social Influence, and Religious Beliefs

The current study examined the sociodemographic and psychosocial variables that predicted being at risk for low health literacy among a population of racially and ethnically diverse patients accessing primary care services at community-based clinics. Participants (N = 416) were aged 50–75 years, currently not up-to-date with colorectal cancer (CRC) screening, at average CRC risk, and enrolled in a randomized controlled trial (RCT) aimed at promoting CRC screening. Participants completed a baseline interview that assessed health literacy as measured by Rapid Estimate of Adult Literacy in Medicine-Revised, sociodemographic factors, and psychosocial variables (e.g., health beliefs) prior to randomization and receipt of an intervention. Thirty-six percent of the participants were found to be at risk for low health literacy. Sociodemographic and psychosocial variables were assessed as predictors of being at risk for low health literacy using logistic regression. In the final model, predictors were male gender, being from a racial/ethnic minority group, being unable to work, having higher social influence scores, and having higher religious belief scores. These findings suggest several patient characteristics that may be associated with low health literacy, and highlight the importance of supporting all patients through simplified and clear communications and information to improve understanding of CRC screening information.
