Healthy colon, healthy life (colon sano, vida sana): colorectal cancer screening among Latinos in Santa Clara, California

Cancer screening and breast cancer family history in Spanish-speaking Hispanic/Latina women in California

Background

Breast cancer is the most common cancer among women in the U.S. and the leading cause of cancer death among Hispanics/Latinas (H/L). H/L are less likely than Non-H/L White (NHW) women to be diagnosed in the early stages of this disease. Approximately 5-10% of breast cancer can be attributed to inherited genetic mutations in high penetrance genes such as BRCA1/2. Women with pathogenic variants in these genes have a 40-80% lifetime risk of breast cancer. Past studies have shown that genetic counseling can help women and their families make informed decisions about genetic testing and early cancer detection or risk-reduction strategies. However, H/L are 3.9-4.8 times less likely to undergo genetic testing than NHW women. We developed a program to outreach and educate the H/L community about hereditary breast cancer, targeting monolingual Spanish-speaking individuals in California. Through this program, we have assessed cancer screening behavior and identified women who might benefit from genetic counseling in a population that is usually excluded from cancer research and care.

Materials and Methods

The "Tu Historia Cuenta" program is a promotores-based virtual outreach and education program including the cities of San Francisco, Sacramento, and Los Angeles. Participants responded to three surveys: a demographic survey, a breast cancer family history survey, and a feedback survey. Survey responses were described for participants and compared by area where the program took place using chi-square, Fisher exact tests, and t tests. Multinomial logistic regression models were used for multivariate analyses.

Results and Conclusion

We enrolled 1042 women, 892 completed the cancer family history survey and 62 (7%) provided responses compatible with referral to genetic counseling. We identified 272 women (42.8% ages 40 to 74 years) who were due for mammograms, 250 women (24.7% ages 25 to 65 years) due for Papanicolaou test, and 189 women (71.6% ages 50+) due for colorectal cancer screening. These results highlight the need of additional support for programs that spread awareness about cancer risk and facilitate access to resources, specifically within the H/L community.

Telephone Reminders Improve Fecal Immunochemical Test Return Rates

INTRODUCTION

The aim of this study was to investigate the effect of a structured telephone reminder system on completion rates of screening fecal immunochemical tests.

METHODS

Fecal immunochemical test (FIT) return rates were compared among patients who received a telephone reminder after 14 days and those who did not receive a reminder.

RESULTS

There was a significantly higher return rate among patients who received a telephone reminder. Automated FIT tracking processes failed to capture a significant percentage of returned FITs compared with manual tracking processes.

DISCUSSION

These results support telephone reminders as an effective modality to increase FIT return rates.

Randomized Controlled Trial of Advance Notification Phone Calls vs Text Messages Prior to Mailed Fecal Test Outreach

BACKGROUND & AIMS

Mailing fecal immunochemical test (FITs) to individuals who are due for screening (mailed FIT outreach) increases colorectal cancer (CRC) screening. Little is known about how phone-based advance notifications (primers) affect the effectiveness of mailed FIT outreach programs.

METHODS

We performed a prospective study of patients at a large urban health center, 50-75 years old and due for screening, with no record of a prior FIT. Participants were randomly assigned to groups that received a live phone call primer (n = 1203) or a text message primer (n = 1622), from June through December 2018. The participants were then mailed a FIT kit, followed by 2 automated calls, and live reminder calls delivered by the care team. The main outcome was completion of FIT within 3 months of assignment to the live phone call or text message group.

RESULTS

Participants had a FIT completion rate of 16.8%, a mean age of 58 years, and 80% were Latino. In adjusted intention to treat analyses (n = 2825), FIT completion rates were higher in the patients assigned to receive a live phone call vs text message primer (percentage point difference, 3.3%; 95% CI, 0.4%-6.2%). Between-group differences increased to 7.3% points (95% CI, 3.6%-11.0%) in the per-protocol analysis of 2144 participants reached by the text message (1320/1622, 81%), live call (438/1203, 36%), or voice message (386/1203, 32%). This rate increased to 14.9% points (95% CI; 9.6%-20.1%) in the per-protocol analysis of 1758 participants reached by the text message or reached by the live call.

CONCLUSIONS

In a randomized trial, advance notification live phone calls outperformed text messages in prompting health center patients who had not previously completed a FIT to complete a mailed FIT. Clinicaltrials.gov no: NCT03167125.

Challenges in assessing population reach in a pragmatic trial

Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC) was a pragmatic cluster-randomized trial conducted at federally qualified health centers and designed to “Reach” as many unscreened patients as possible by directly mailing them fecal screening tests.

STOP CRC used an electronic health record registry to identify individuals' needing CRC screening and mail interventions to them. The registry was updated daily removing individuals completing CRC screening or those who no longer were clinic patients. Reach, a component RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance), is defined as the absolute number, percent, and representativeness of individuals “willing to participate in” or “exposed to” an initiative. We describe the complexities of measuring Reach in a pragmatic trial.

Overall 21,134 patients were on the registry list for at least one day, with 18,226 remaining after removing patients completing screening before any mailings. Observed Reached (the percent of individuals exposed to the intervention) using each denominator was 30.7% and 35.6% respectively. Reach improved only modestly after accounting for factors that made it impossible for clinics to send mailings. Few differences were observed in demographic and health care utilization factors among individuals Reached versus not Reached, suggesting that health center Implementation was more influential than patients' willingness or ability to participate.

A pragmatic definition of Reach that accounted for dynamic changes the absolute number eligible and the proportion exposed was more useful than traditional definitions of Reach. Actual Reach was dependent on Implementation and not patient level characteristics.

Latinas' Colorectal Cancer Screening Knowledge, Barriers to Receipt, and Feasibility of Home-Based Fecal Immunochemical Testing

Latinas' high colorectal cancer (CRC) mortality makes them a priority population for CRC screening. CRC screening knowledge, perceived barriers, and feasibility of using the Fecal Immunochemical Test (FIT) was assessed among Latinas in Utah. Participants aged ≥50 (n = 95) were surveyed about knowledge and barriers to CRC screening. 27 participants completed a FIT and evaluation survey. Fisher's exact tests assessed sociodemographic correlates of CRC screening outcomes. Most participants were overdue for CRC screening (n = 81, 85%). Age, acculturation, education, and employment were significantly associated with CRC screening status and/or reasons for being overdue (e.g., not knowing about the test, cost). All participants who received a FIT completed it, felt it was easy to use, and reported they would use it again. Latinas had limited awareness of CRC, CRC screenings, and experienced barriers to CRC screening (e.g., limited access, cost), but were willing to utilize a low-cost home-based FIT.

Effect of Reminding Patients to Complete Fecal Immunochemical Testing: A Comparative Effectiveness Study of Automated and Live Approaches

BACKGROUND

The Community Preventive Services Task Force recommends multi-component interventions, including patient reminders, to improve uptake of colorectal cancer screening.

OBJECTIVE

We sought to compare the effectiveness of different forms of reminders for a direct-mail fecal immunochemical test (FIT) program.

DESIGN

Patient-randomized controlled trial.

PARTICIPANTS

2772 adults aged 50-75, not up to date with colorectal cancer screening recommendations, with a clinic visit in the previous year at any of four participating health center clinics.

INTERVENTION

Participants were mailed an introductory letter and FIT. Those who did not complete their FIT within 3 weeks were randomized to receive (1) a reminder letter, (2) two automated phone calls, (3) two text messages, (4) a live phone call, (5) a reminder letter and a live phone call, (6) two automated phone calls and a live phone call, or (7) two text messages and a live phone call. Patients with a patient portal account were sent two email reminders, but were not randomized.

MAIN MEASURES

FIT return rates for each group, 6 months following randomization.

KEY RESULTS

A total of 255 (10%) participants returned their FIT within 3 weeks of the mailing. Among randomized participants (n = 2010), an additional 25.5% returned their FITs after reminders were delivered (estimated overall return rate = 32.7%). In intention-to-treat analysis, compared to the group allocated to receive a reminder letter, return rates were higher for the group assigned to receive the live phone call (OR = 1.51 [1.03-2.21]) and lower for the group assigned to receive text messages (OR = 0.66 [0.43-0.99]). Reminder effectiveness differed by language preference.

CONCLUSIONS

Our data suggest that FIT reminders that included a live call were more effective than reminders that relied solely on written communication (a text message or letter).

Priorities, concerns and unmet needs among Haitians in Boston after the 2010 earthquake

In January 2010, a massive earthquake struck Haiti. The devastation not only affected those living in Haiti at the time but also those Haitians living in the United States (U.S.). Few studies have assessed the degree of impact of the earthquake in U.S. Haitian communities. The purpose of this study was to elicit information about health priorities, concerns and resources needed to improve the delivery of health and social care for Haitians in Boston, MA. We conducted six focus groups among 78 individuals in the spring of 2011. Participants were recruited through community organisations, including churches, Haitian social service centres, restaurants and by word of mouth. Analysis of qualitative data revealed an enormous psychological, emotional, financial and physical toll experienced by Boston-area Haitians following the earthquake. Participants described increased distress, depressive episodes, headaches and financial hardship. They also noted insufficient resources to meet the increased needs of those living in the U.S., and those who had immigrated after the earthquake. Most participants cited an increased need for mental health services, as well as assistance with finding employment, navigating the immigration system, and balancing the health and financial needs of families in the U.S. and in Haiti. Despite this, many reported that the tragedy created a sense of unity and solidarity within the Haitian community. These findings corroborate the need for culturally and linguistically appropriate mental health services, as well as for employment, immigration and healthcare navigation services. Participants suggested that interventions be offered through Haitian radio and television stations, as well as group events held in churches. Further research should assess the need for and barriers to utilisation of mental health services among the Haitian community. A multi-faceted approach that includes a variety of outreach strategies implemented through multiple channels may offer a means of improving awareness of and access to health and social services.

Characterization of the Hispanic or latino population in health research: a systematic review

The size and diversity of the Hispanic population in the United States has dramatically increased, with vast implications for health research. We conducted a systematic review of the characterization of the Hispanic population in health research and described its implications. Relevant studies were identified by searches of PubMed, Embase Scopus, and Science/Social Sciences Citation Index from 2000 to 2011. 131 articles met criteria. 56% of the articles reported only "Hispanic" or "Latino" as the characteristic of the Hispanic research population while no other characteristics were reported. 29% of the articles reported language, 27% detailed country of origin and 2% provided the breakdown of race. There is great inconsistency in reported characteristics of Hispanics in health research. The lack of detailed characterization of this population ultimately creates roadblocks in translating evidence into practice when providing care to the large and increasingly diverse Hispanic population in the US.

Physician counseling on colorectal cancer screening and receipt of screening among Latino patients

BACKGROUND

Latinos have lower rates of colorectal cancer (CRC) screening and later stage diagnosis than Whites, which may be partially explained by physician communication factors.

OBJECTIVE

We assessed associations between patient-reported physician counseling regarding CRC screening and receipt of CRC screening among Latino primary care patients.

DESIGN

This was a cross-sectional telephone survey.

PARTICIPANTS

The participants of this study were Latino primary care patients 50 years of age or older, with one or more visits during the preceding year.

MAIN MEASURES

We developed patient-reported measures to assess whether physicians provided explanations of CRC risks and tests, elicited patients' barriers to CRC screening, were responsive to patients' concerns about screening, and encouraged patients to be screened. Outcomes were patient reports of receipt of endoscopy (sigmoidoscopy or colonoscopy) and fecal occult blood test (FOBT) within recommended guidelines.

KEY RESULTS

Of 817 eligible patients contacted, 505 (62 %) completed the survey; mean age was 61 years (SD 8.4), 69 % were women, and 53 % had less than high school education. Forty-six percent reported obtaining endoscopy (with or without FOBT), 13 % reported FOBT only, and 41 % reported no CRC screening. In bivariate analyses, physician explanations, elicitation of barriers, responsiveness to concerns, and greater encouragement for screening were associated with receipt of endoscopy (p < 0.001), and explanations (p < 0.05) and encouragement (p < 0.001) were associated with FOBT. Adjusting for covariates, physician explanations (OR = 1.27; 95 % CI 1.03, 1.58) and greater physician encouragement (OR = 6.74; 95 % CI 3.57, 12.72) were associated with endoscopy; patients reporting quite a bit/a lot of physician encouragement had six times higher odds of obtaining the FOBT as those reporting none/a little encouragement (OR = 6.54; 95 % CI 2.76, 15.48).

CONCLUSIONS

Among primarily lower-socioeconomic status Latino patients, the degree to which patients perceived that physicians encouraged CRC screening was more strongly associated with screening than with providing risk information, eliciting barriers, and responding to their concerns about screening.

Reasons for non-response to a direct-mailed FIT kit program: lessons learned from a pragmatic colorectal-cancer screening study in a federally sponsored health center

Colorectal cancer screening rates are below optimal. As part of a pilot clinic-based pragmatic study aiming to raise rates of colorectal-cancer screening, we explored patients' reasons for not responding to a direct-mailed screening invitation. We conducted telephone interviews with patients who were mailed a fecal immunochemical test (FIT) but who did not return it to the lab. Interviews were audio-recorded, transcribed, and coded for thematic analysis. We met our goal of 20 interviews (10 in English and 10 Spanish; 75 % female). Reasons for not completing tests were fear of results or cost of follow-up colonoscopy (n = 9); not having received the test in the mail (n = 7); concerns about mailing fecal matter or that test results could be mixed up (n = 6); and being busy or forgetful (n = 4). Efforts to improve uptake of colorectal cancer screening in a direct-mailed program ought to address concerns identified in our study.

Associations of census-tract poverty with subsite-specific colorectal cancer incidence rates and stage of disease at diagnosis in the United States

Background. It remains unclear whether neighborhood poverty contributes to differences in subsite-specific colorectal cancer (CRC) incidence. We examined associations between census-tract poverty and CRC incidence and stage by anatomic subsite and race/ethnicity. Methods. CRC cases diagnosed between 2005 and 2009 from 15 states and Los Angeles County (N = 278,097) were assigned to 1 of 4 groups based on census-tract poverty. Age-adjusted and stage-specific CRC incidence rates (IRs) and incidence rate ratios (IRRs) were calculated. Analyses were stratified by subsite (proximal, distal, and rectum), sex, race/ethnicity, and poverty. Results. Compared to the lowest poverty areas, CRC IRs were significantly higher in the most impoverished areas for men (IRR = 1.14 95% CI 1.12-1.17) and women (IRR = 1.06 95% CI 1.05-1.08). Rate differences between high and low poverty were strongest for distal colon (male IRR = 1.24 95% CI 1.20-1.28; female IRR = 1.14 95% CI 1.10-1.18) and weakest for proximal colon. These rate differences were significant for non-Hispanic whites and blacks and for Asian/Pacific Islander men. Inverse associations between poverty and IRs of all CRC and proximal colon were found for Hispanics. Late-to-early stage CRC IRRs increased monotonically with increasing poverty for all race/ethnicity groups. Conclusion. There are differences in subsite-specific CRC incidence by poverty, but associations were moderated by race/ethnicity.

Strategies and Opportunities to STOP Colon Cancer in Priority Populations: design of a cluster-randomized pragmatic trial

BACKGROUND

Colorectal cancer is the second-leading cause of cancer deaths in the United States. The Strategies and Opportunities to Stop Colorectal Cancer (STOP CRC) in Priority Populations study is a pragmatic trial and a collaboration between two research institutions and a network of more than 200 safety net clinics. The study will assess the effectiveness of a system-based intervention designed to improve the rates of colorectal-cancer screening using fecal immunochemical testing (FIT) in federally qualified health centers in Oregon and Northern California.

MATERIAL AND METHODS

STOP CRC is a cluster-randomized comparative-effectiveness pragmatic trial enrolling 26 clinics. Clinics will be randomized to one of two arms. Clinics in the intervention arm (1) will use an automated, data-driven, electronic health record-embedded program to identify patients due for colorectal screening and mail FIT kits (with pictographic instructions) to them; (2) will conduct an improvement process (e.g. Plan-Do-Study-Act) to enhance the adoption, reach, and effectiveness of the program. Clinics in the control arm will provide opportunistic colorectal-cancer screening to patients at clinic visits. The primary outcomes are: proportion of age- and screening-eligible patients completing a FIT within 12months; and cost, cost-effectiveness, and return on investment of the intervention.

CONCLUSIONS

This large-scale pragmatic trial will leverage electronic health record information and existing clinic staff to enroll a broad range of patients, including many with historically low colorectal-cancer screening rates. If successful, the program will provide a model for a cost-effective and scalable method to raise colorectal-cancer screening rates.

Religious beliefs and cancer screening behaviors among Catholic Latinos: implications for faith-based interventions

Although most U.S. Latinos identify as Catholic, few studies have focused on the influence of this religious tradition on health beliefs among this population. This study explores the role of Catholic religious teachings, practices, and ministry on cancer screening knowledge, attitudes, and behaviors among Latinos. Eight focus groups were conducted with 67 Catholic Latino parishioners in Massachusetts. Qualitative analysis provided evidence of strong reliance on faith, God, and parish leaders for health concerns. Parishes were described as vital sources of health and social support, playing a central role in the community's health. Participants emphasized that their religious beliefs promote positive health behaviors and health care utilization, including the use of cancer screening services. In addition, they expressed willingness to participate in cancer education programs located at their parishes and provided practical recommendations for implementing health programs in parishes. Implications for culturally appropriate health communication and faith-based interventions are discussed.

Strategies and opportunities to STOP colon cancer in priority populations: pragmatic pilot study design and outcomes

Background

Colorectal-cancer is a leading cause of cancer death in the United States, and Latinos have particularly low rates of screening. Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC) is a partnership among two research institutions and a network of safety net clinics to promote colorectal cancer screening among populations served by these clinics. This paper reports on results of a pilot study conducted in a safety net organization that serves primarily Latinos.

Methods

The study assessed two clinic-based approaches to raise rates of colorectal-cancer screening among selected age-eligible patients not up-to-date with colorectal-cancer screening guidelines. One clinic each was assigned to: (1) an automated data-driven Electronic Health Record (EHR)-embedded program for mailing Fecal Immunochemical Test (FIT) kits (Auto Intervention); or (2) a higher-intensity program consisting of a mailed FIT kit plus linguistically and culturally tailored interventions delivered at the clinic level (Auto Plus Intervention). A third clinic within the safety-net organization was selected to serve as a passive control (Usual Care). Two simple measurements of feasibility were: 1) ability to use real-time EHR data to identify patients eligible for each intervention step, and 2) ability to offer affordable testing and follow-up care for uninsured patients.

Results

The study was successful at both measurements of feasibility. A total of 112 patients in the Auto clinic and 101 in the Auto Plus clinic met study inclusion criteria and were mailed an introductory letter. Reach was high for the mailed component (92.5% of kits were successfully mailed), and moderate for the telephone component (53% of calls were successful completed). After exclusions for invalid address and other factors, 206 (109 in the Auto clinic and 97 in the Auto Plus clinic) were mailed a FIT kit. At 6 months, fecal test completion rates were higher in the Auto (39.3%) and Auto Plus (36.6%) clinics compared to the usual-care clinic (1.1%).

Conclusions

Findings showed that the trial interventions delivered in a safety-net setting were both feasible and raised rates of colorectal-cancer screening, compared to usual care. Findings from this pilot will inform a larger pragmatic study involving multiple clinics.

Gender differences in attitudes impeding colorectal cancer screening

Background

Colorectal cancer screening (CRCS) is the only type of cancer screening where both genders reduce risks by similar proportions with identical procedures. It is an important context for examining gender differences in disease-prevention, as CRCS significantly reduces mortality via early detection and prevention. In efforts to increase screening adherence, there is increasing acknowledgment that obstructive attitudes prevent CRCS uptake. Precise identification of the gender differences in obstructive attitudes is necessary to improve uptake promotion. This study randomly sampled unscreened, screening - eligible individuals in Ontario, employing semi-structured interviews to elicit key differences in attitudinal obstructions towards colorectal cancer screening with the aim of deriving informative differences useful in planning promotions of screening uptake.

Methods

N = 81 participants (49 females, 32 males), 50 years and above, with no prior CRCS, were contacted via random-digit telephone dialing, and consented via phone-mail contact. Altogether, N = 4,459 calls were made to yield N = 85 participants (1.9% response rate) of which N = 4 participants did not complete interviews. All subjects were eligible for free-of-charge CRCS in Ontario, and each was classified, via standard interview by CRCS screening decision-stage. Telephone-based, semi-structured interviews (SSIs) were employed to investigate gender differences in CRCS attitudes, using questions focused on 5 attitudinal domains: 1) Screening experience at the time of interview; 2) Barriers to adherence; 3) Predictors of Adherence; 4) Pain-anxiety experiences related to CRCS; 5) Gender-specific experiences re: CRCS, addressing all three modalities accessible through Ontario’s program: a) fecal occult blood testing; b) flexible sigmoidoscopy; c) colonoscopy.

Results

Interview transcript analyses indicated divergent themes related to CRCS for each gender: 1) bodily intrusion, 2) perforation anxiety, and 3) embarrassment for females and; 1) avoidant procrastination with underlying fatalism, 2) unnecessary health care and 3) uncomfortable vulnerability for males. Respondents adopted similar attitudes towards fecal occult blood testing, flexible sigmoidoscopy and colonoscopy, and were comparable in decision stage across tests. Gender differences were neither closely tied to screening stage nor modality. Women had more consistent physician relationships, were more screening-knowledgeable and better able to articulate views on screening. Men reported less consistent physician relationships, were less knowledgeable and kept decision-making processes vague and emotionally distanced (i.e. at ‘arm’s length’).

Conclusions

Marked differences were observed in obstructive CRCS attitudes per gender. Females articulated reservations about CRCS-associated distress and males suppressed negative views while ambiguously procrastinating about the task of completing screening. Future interventions could seek to reduce CRCS-related stress (females) and address the need to overcome procrastination (males).

Using an Automated Data-driven, EHR-Embedded Program for Mailing FIT kits: Lessons from the STOP CRC Pilot Study

Background

The Strategies and Opportunities to Stop Colorectal Cancer (STOP CRC) study is collaboration among two research institutions and health-systems partners. The main study, scheduled to begin in 2014, will assess effectiveness of an intervention program using electronic health record (EHR) clinical decision support (CDS) tools to improve rates of colorectal-cancer screening in federally qualified health centers (FQHCs). Very few studies, and no large studies, aimed at raising CRC screening rates have utilized an EHR-embedded system.

Study design

We piloted the use of an EHR-embedded real-time patient registry reporting tool in a pilot study undertaken prior to beginning our main CRC screening study. The pilot study goal was to assess feasibility and effectiveness of two clinic-based approaches to raising rates of colorectal cancer screening among selected patients aged 50–74 who were not up-to-date with colorectal-cancer screening guidelines. We used work sessions and qualitative interviews with clinic personnel to assess performance of the tool, as well as to identify specific elements of the tool’s functionality needing refinement.

Results

Two critical elements of the EHR tool allowed us to mail FIT kits efficiently to appropriate patients: (1) having a direct interface with the laboratory that processed the FITs, thus allowing for real-time updates to the registry; and (2) being able to place lab orders from a list of selected patients. We identified the following elements that needed refining: the use of Health Maintenance (EHR function for tracking screening eligibility and due dates incorporating STOP CRC inclusion and exclusion criteria), and the development of report templates for identifying patients eligible for each step.

Conclusion

We found that most elements of our EHR-embedded program worked well and that specific refinement may improve the accuracy of identifying patients at each step. Our findings can inform future efforts to build EHR-embedded CDS tools for preventive services.

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.

Patient and provider factors associated with colorectal cancer screening in safety net clinics serving low-income, urban immigrant Latinos

BACKGROUND

Latinos have lower colorectal cancer screening rates than Whites.

METHODS

We reviewed a random sample of charts between July 2009 and February 2010 of safety-net clinic of 840 immigrants (50 years and older) from Central and South America receiving care. Logistic regression evaluated associations of ever vs. never screening, patient and physician factors.

RESULTS

Ever screening rates were 24.5%, and only 17% of charts noted a physician screening recommendation. However, the odds of screening were 9.89 times higher (95% CI: 6.25-15.64, p<.001) among patients with a physician recommendation vs. those without, considering covariates. The odds of screening were 0.61 times lower (95% CI: 0.40-0.92, p=.02) in patients with a body mass index ≥ 30 vs. <30.

CONCLUSIONS

While rates were low, determinants of screening were similar in this Latino subgroup to those reported in other Latino and non-Latino populations. Low rates of documented physician screening recommendations may indicate a potential missed opportunity for cancer control in safety-net clinics.

A review of cancer in U.S. Hispanic populations

There are compelling reasons to conduct studies of cancer in Hispanics, the fastest growing major demographic group in the United States (from 15% to 30% of the U.S. population by 2050). The genetically admixed Hispanic population coupled with secular trends in environmental exposures and lifestyle/behavioral practices that are associated with immigration and acculturation offer opportunities for elucidating the effects of genetics, environment, and lifestyle on cancer risk and identifying novel risk factors. For example, traditional breast cancer risk factors explain less of the breast cancer risk in Hispanics than in non-Hispanic whites (NHW), and there is a substantially greater proportion of never-smokers with lung cancer in Hispanics than in NHW. Hispanics have higher incidence rates for cancers of the cervix, stomach, liver, and gall bladder than NHW. With respect to these cancers, there are intriguing patterns that warrant study (e.g., depending on country of origin, the five-fold difference in gastric cancer rates for Hispanic men but not Hispanic women). Also, despite a substantially higher incidence rate and increasing secular trend for liver cancer in Hispanics, there have been no studies of Hispanics reported to date. We review the literature and discuss study design options and features that should be considered in future studies.

Patient-provider sex and race/ethnicity concordance: a national study of healthcare and outcomes

BACKGROUND

Increasing patient-provider sex and race/ethnicity concordance has been proposed to improve healthcare and help mitigate health disparities, but the relationship between concordance and health outcomes remains unclear.

OBJECTIVE

To examine associations of patient-provider sex, race/ethnicity, and dual concordance with healthcare measures.

RESEARCH DESIGN AND PARTICIPANTS

Analyses of data from adult respondents indicating a usual source of healthcare (N=22,440) in the 2002 to 2007 Medical Expenditure Panel Surveys (each a 2-year panel).

MEASURES

Year 1 provider communication, sex-neutral (colorectal cancer screening, influenza vaccination) and sex-specific (mammography, Papanicolaou smear, prostate-specific antigen) prevention; and year 2 health status (SF-12). Analyses adjusted for patient sociodemographics and health variables, and healthcare provider (usual source of care) sex and race/ethnicity.

RESULTS

Of 24 concordance assessments, 3 were statistically significant. Women with female providers were more likely to report mammography adherence [average adjusted marginal effect=3.9%, 95% confidence interval (CI): 1.6%, 6.2%; P<0.01]. Respondents reporting dual concordance were less likely to rate provider communication in the highest quartile (average adjusted marginal effect =-4.2%, 95% CI: -8.1%, -0.2%; P=0.04), but dual concordance was associated with higher adjusted SF-12 Physical Component Summary scores (0.58 points, 95% CI: 0.00, 1.15; P=0.05).

CONCLUSIONS

Little evidence of clinical benefit resulting from sex or race/ethnicity concordance was found. Greater matching of patients and providers by sex and race/ethnicity is unlikely to mitigate health disparities.
