A culturally tailored navigator program for colorectal cancer screening in a community health center: a randomized, controlled trial

Comparative effectiveness of fecal immunochemical test outreach, colonoscopy outreach, and usual care for boosting colorectal cancer screening among the underserved: a randomized clinical trial

IMPORTANCE

Colorectal cancer (CRC) screening saves lives, but participation rates are low among underserved populations. Knowledge on effective approaches for screening the underserved, including best test type to offer, is limited.

OBJECTIVE

To determine (1) if organized mailed outreach boosts CRC screening compared with usual care and (2) if FIT is superior to colonoscopy outreach for CRC screening participation in an underserved population.

DESIGN, SETTING, AND PARTICIPANTS

We identified uninsured patients, not up to date with CRC screening, age 54 to 64 years, served by the John Peter Smith Health Network, Fort Worth and Tarrant County, Texas, a safety net health system.

INTERVENTIONS

Patients were assigned randomly to 1 of 3 groups. One group was assigned to fecal immunochemical test (FIT) outreach, consisting of mailed invitation to use and return an enclosed no-cost FIT (n = 1593). A second was assigned to colonoscopy outreach, consisting of mailed invitation to schedule a no-cost colonoscopy (n = 479). The third group was assigned to usual care, consisting of opportunistic primary care visit–based screening (n = 3898). In addition, FIT and colonoscopy outreach groups received telephone follow-up to promote test completion.

MAIN OUTCOME MEASURES

Screening participation in any CRC test within 1 year after randomization.

RESULTS

Mean patient age was 59 years; 64% of patients were women. The sample was 41% white, 24% black, 29% Hispanic, and 7% other race/ethnicity. Screening participation was significantly higher for both FIT (40.7%) and colonoscopy outreach (24.6%) than for usual care (12.1%) (P < .001 for both comparisons with usual care). Screening was significantly higher for FIT than for colonoscopy outreach (P < .001). In stratified analyses, screening was higher for FIT and colonoscopy outreach than for usual care, and higher for FIT than for colonoscopy outreach among whites, blacks, and Hispanics (P < .005 for all comparisons). Rates of CRC identification and advanced adenoma detection were 0.4% and 0.8% for FIT outreach, 0.4% and 1.3% for colonoscopy outreach, and 0.2% and 0.4% for usual care, respectively (P < .05 for colonoscopy vs usual care advanced adenoma comparison; P > .05 for all other comparisons). Eleven of 60 patients with abnormal FIT results did not complete colonoscopy. CONCLUSIONS AND REVELANCE: Among underserved patients whose CRC screening was not up to date, mailed outreach invitations resulted in markedly higher CRC screening compared with usual care. Outreach was more effective with FIT than with colonoscopy invitation.

Implementation of culturally targeted patient navigation system for screening colonoscopy in a direct referral system

Low-income minorities often face system-based and personal barriers to screening colonoscopy (SC). Culturally targeted patient navigation (CTPN) programs employing professional navigators (Pro-PNs) or community-based peer navigators (Peer-PNs) can help overcome barriers but are not widely implemented. In East Harlem, NY, USA, where approximately half the residents participate in SC, 315 African American patients referred for SC at a primary care clinic with a Direct Endoscopic Referral System were recruited between May 2008 and May 2010. After medical clearance, 240 were randomized to receive CTPN delivered by a Pro-PN (n = 106) or Peer-PN (n = 134). Successful navigation was measured by SC adherence rate, patient satisfaction and navigator trust. Study enrollment was 91.4% with no significant differences in SC adherence rates between Pro-PN (80.0%) and Peer-PN (71.3%) (P = 0.178). Participants in both groups reported high levels of satisfaction and trust. These findings suggest that CTPN Pro-PN and Peer-PN programs are effective in this urban primary care setting. We detail how we recruited and trained navigators, how CTPN was implemented and provide a preliminary answer to our questions of the study aims: can peer navigators be as effective as professionals and what is the potential impact of patient navigation on screening adherence?

Effectiveness of a theory-based intervention to increase colorectal cancer screening among Iranian health club members: a randomized trial

Colorectal cancer is the third most commonly diagnosed cancer and the fourth leading cause of death in the world. There are few published studies that have used theory-based interventions designed to increase colorectal cancer screening in community lay health organizations. The present study was guided by the theoretical concepts of the preventive health model. Twelve health clubs of a municipal district in Tehran were randomized to two study groups with equal ratio. The control group received usual services throughout the study while the intervention group also received a theory-based educational program on colorectal cancer screening plus a reminder call. Screening behavior, the main outcome, was assessed 4 months after randomization. A total of 360 members aged 50 and older from 12 health clubs completed a baseline survey. Participants in the intervention group reported increased knowledge of colorectal cancer and screening tests at 4 months follow-up (p's < .001). Moreover, exposure to the theory-based intervention significantly improved self-efficacy, perceived susceptibility, efficacy of screening, social support, and intention to be screened for colorectal cancer, from baseline to 4 months follow-up (p's < .001). The screening rate for colorectal cancer was significantly higher in the intervention group compared to the control group (odds ratio = 15.93, 95% CI = 5.57, 45.53). Our theory-based intervention was found to have a significant effect on colorectal cancer screening use as measured by self-report. The findings could have implications for colorectal cancer screening program development and implementation in primary health care settings and through other community organizations.

Self-reported barriers to colorectal cancer screening in a racially diverse, low-income study population

Colorectal cancer (CRC) screening is underutilized, especially in low income, high minority populations. We examined the effect test-specific barriers have on colonoscopy and fecal immunochemical test (FIT) completion, what rationales are given for non-completion, and what "switch" patterns exist when participants are allowed to switch from one test to another. Low income adults who were not up-to-date with CRC screening guidelines were recruited from safety-net clinics and offered colonoscopy or FIT (n = 418). Follow up telephone surveys assessed test-specific barriers. Test completion was determined from patient medical records. For subjects who desired colonoscopy at baseline, finding a time to come in and transportation applied more to non-completers than completers (p = 0.001 and p < 0.001, respectively). For participants who initially wanted FIT, keeping track of cards, never putting stool on cards, and not remembering to mail cards back applied more to non-completers than completers (p = 0.003, p = 0.006, and p < 0.001, respectively). The most common rationale given for not completing screening was a desire for the other screening modality: 7 % of patients who initially preferred screening by FIT completed colonoscopy, while 8 % of patients who initially preferred screening by colonoscopy completed FIT. We conclude that test-specific barriers apply more to subjects who did not complete CRC screening. As a common rationale for test non-completion is a desire to receive a different screening modality, our findings suggest screening rates could be increased by giving patients the opportunity to switch tests after an initial choice is made.

Education provides significant benefits to patients with hepatitis B virus or hepatitis C virus infection: a systematic review

BACKGROUND & AIMS

Education of individuals who are at risk for, or have been diagnosed with, chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections can improve their participation in disease management. We performed a systematic review to evaluate the effects of educational interventions for patients with HBV or HCV infections.

METHODS

We searched multiple databases for peer-reviewed studies of individuals with HBV or HCV infection, or those at risk for infection. Our final analysis included 14 studies that evaluated any educational intervention and reported the effectiveness or patient outcomes relevant to the intervention (7 patients with HCV infection, 4 patients with HBV infection, and 3 patients with either). Data extracted from studies included details on educational interventions, patient populations, comparison groups, and outcome measures. The quality of each study was appraised.

RESULTS

Types of educational interventions assessed ranged from information websites and nurse-led sessions to community-wide and institutional programs. The educational interventions showed significant (P < .05) improvements to patients' knowledge about their disease, behaviors (including testing and uptake of vaccination), willingness to commence and adhere to treatment, and other outcomes such as self-efficacy and vitality or energy scores. These significant benefits were shown in 5 of 7 studies of HBV infection and 8 of 10 studies of HCV infection. On a 20-point quality scale, study scores ranged from 6 to 19.

CONCLUSIONS

Simple educational interventions for patients with HBV or HCV infection significantly increase patients' knowledge about their disease. More complex, multimodal educational interventions seem to cause behavioral changes that increase rates of testing, vaccination (for HBV), and treatment.

Implementing the CDC's Colorectal Cancer Screening Demonstration Program: wisdom from the field

BACKGROUND

Colorectal cancer, as the second leading cause of cancer-related deaths among men and women in the United States, represents an important area for public health intervention. Although colorectal cancer screening can prevent cancer and detect disease early when treatment is most effective, few organized public health screening programs have been implemented and evaluated. From 2005 to 2009, the Centers for Disease Control and Prevention funded 5 sites to participate in the Colorectal Cancer Screening Demonstration Program (CRCSDP), which was designed to reach medically underserved populations.

METHODS

The authors conducted a longitudinal, multiple case study to analyze program implementation processes. Qualitative methods included interviews with 100 stakeholders, 125 observations, and review of 19 documents. Data were analyzed within and across cases.

RESULTS

Several themes related to CRCSDP implementation emerged from the cross-case analysis: the complexity of colorectal cancer screening, the need for teamwork and collaboration, integration of the program into existing systems, the ability of programs to use wisdom at the local level, and the influence of social norms. Although these themes were explored independently from 1 another, interaction across themes was evident.

CONCLUSIONS

Colorectal cancer screening is clinically complex, and its screening methods are not well accepted by the general public; both of these circumstances have implications for program implementation. Using patient navigation, engaging in transdisciplinary teamwork, assimilating new programs into existing clinical settings, and deferring to local-level wisdom together helped to address complexity and enhance program implementation. In addition, public health efforts must confront negative social norms around colorectal cancer screening.

Factors associated with never being screened for colorectal cancer

Colorectal cancer (CRC) screening is underused in the United States, and non-adherence with screening recommendations is high in some populations. This study describes the characteristics of people who have never been screened for CRC. In addition, we use the health belief model to examine the constructs associated with screening behavior. We used data from the 2010 Behavioral Risk Factor Surveillance System (BRFSS) to create three study outcomes: people who have been screened for CRC and are up-to-date with current recommendations, people who have been screened but are not up-to-date, and people who have never been screened. We used multivariate logistic regression modeling to calculate predicted marginal estimates examining the associations between the screening outcomes and demographic and Health Belief Model (HBM) characteristics. Overall 29% of respondents had never been screened for CRC. In the adjusted model, 36.6% of US adults age 50-59 years and 29.1% of US men reported never being screened for CRC. More Asian/Native Hawaiian/Pacific Islander, non-Hispanics (38.2%) reported never being screened than members of other racial and ethnic groups. Nearly 37% of people with less than a high school diploma reported never being screened. We found statistically significant differences among screening outcomes for all demographics and HBM constructs except could not see a doctor because of costs in the last 12 months, where approximately 29% reported no CRC screening. New interventions should focus on those subpopulations that have never been screened for CRC.

Telephone outreach to increase colon cancer screening in medicaid managed care organizations: a randomized controlled trial

PURPOSE

Health Plans are uniquely positioned to deliver outreach to members. We explored whether telephone outreach, delivered by Medicaid managed care organization (MMCO) staff, could increase colorectal cancer (CRC) screening among publicly insured urban women, potentially reducing disparities.

METHODS

We conducted an 18-month randomized clinical trial in 3 MMCOs in New York City in 2008-2010, randomizing 2,240 MMCO-insured women, aged 50 to 63 years, who received care at a participating practice and were overdue for CRC screening. MMCO outreach staff provided cancer screening telephone support, educating patients and helping overcome barriers. The primary outcome was the number of women screened for CRC during the 18-month intervention, assessed using claims.

RESULTS

MMCO staff reached 60% of women in the intervention arm by telephone. Although significantly more women in the intervention (36.7%) than in the usual care (30.6%) arm received CRC screening (odds ratio [OR] = 1.32; 95% CI, 1.08-1.62), increases varied from 1.1% to 13.7% across the participating MMCOs, and the overall increase was driven by increases at 1 MMCO. In an as-treated comparison, 41.8% of women in the intervention arm who were reached by telephone received CRC screening compared with 26.8% of women in the usual care arm who were not contacted during the study (OR = 1.84; 95% CI, 1.38, 2.44); 7 women needed to be reached by telephone for 1 to become screened.

CONCLUSIONS

The telephone outreach intervention delivered by MMCO staff increased CRC screening by 6% more than usual care among randomized women, and by 15.1% more than usual care among previously overdue women reached by the intervention. Our research-based intervention was successfully translated to the health plan arena, with variable effects in the participating MMCOs.

Culturally targeted patient navigation for increasing african americans' adherence to screening colonoscopy: a randomized clinical trial

BACKGROUND

Patient navigation has been an effective intervention to increase cancer screening rates. This study focuses on predicting outcomes of screening colonoscopy for colorectal cancer among African Americans using different patient navigation formats.

METHODS

In a randomized clinical trial, patients more than 50 years of age without significant comorbidities were randomized into three navigation groups: peer-patient navigation (n = 181), pro-patient navigation (n = 123), and standard (n = 46). Pro-patient navigations were health care professionals who conducted culturally targeted navigation, whereas peer-patient navigations were community members trained in patient navigation who also discussed their personal experiences with screening colonoscopy. Two assessments gathered sociodemographic, medical, and intrapersonal information.

RESULTS

Screening colonoscopy completion rate was 75.7% across all groups with no significant differences in completion between the three study arms. Annual income more than $10,000 was an independent predictor of screening colonoscopy adherence. Unexpectedly, low social influence also predicted screening colonoscopy completion.

CONCLUSIONS

In an urban African American population, patient navigation was effective in increasing screening colonoscopy rates to 15% above the national average, regardless of patient navigation type or content.

IMPACT

Because patient navigation successfully increases colonoscopy adherence, cultural targeting may not be necessary in some populations.

Reach, usage, and effectiveness of a Medicaid patient navigator intervention to increase colorectal cancer screening, Cape Fear, North Carolina, 2011

Introduction

Screening for colorectal cancer can reduce incidence and death, but screening is underused, especially among vulnerable groups such as Medicaid patients. Effective interventions are needed to increase screening frequency. Our study consisted of a controlled trial of an intervention designed to improve colorectal cancer screening among Medicaid patients in North Carolina.

Methods

The intervention included a mailed screening reminder letter and decision aid followed by telephone support from an offsite, Medicaid-based, patient navigator. The study included 12 clinical practices, 6 as intervention practices and 6 as matched controls. Eligible patients were aged 50 years or older, covered by Medicaid, and identified from Medicaid claims data as not current with colorectal cancer screening recommendations. We reviewed Medicaid claims data at 6 months and conducted multivariate logistic regression to compare participant screening in intervention practices with participants in control practices. We controlled for sociodemographic characteristics.

Results

Most of the sample was black (53.1%) and female (57.2%); the average age was 56.5 years. On the basis of Medicaid claims, 9.2% of intervention participants (n = 22/240) had had a colorectal cancer screening at the 6-month review, compared with 7.5% of control patients (n = 13/174). The adjusted odds ratio when controlling for age, comorbidities, race, sex, and continuous Medicaid eligibility was 1.44 (95% confidence interval, 0.68–3.06). The patient navigator reached 44 participants (27.6%).

Conclusion

The intervention had limited reach and little effect after 6 months on the number of participants screened. Higher-intensity interventions, such as use of practice-based navigators, may be needed to reach and improve screening rates in vulnerable populations.

Improving hepatocellular carcinoma screening: applying lessons from colorectal cancer screening

Hepatocellular carcinoma (HCC) screening is a complex process, with failure at any step in the process contributing to a gap between its efficacy and effectiveness. Important lessons can be learned from colorectal cancer (CRC) screening studies to improve the HCC screening process in clinical practice. Lack of provider recommendations is a barrier for both CRC and HCC screening; however, under-recognition of at-risk individuals appears to be unique to HCC. Future HCC screening interventions should help providers identify at-risk patients as well as promote ordering of HCC screening among those with cirrhosis. Patient adherence, a well-recognized barrier to CRC screening, does not appear to be a major issue in HCC screening. Poor patient adherence may become an important factor in the future when upstream provider-level factors are addressed. Other steps in the screening process, including radiology capacity and timely follow-up, have been demonstrated as barriers for CRC screening but have yet to be assessed for HCC screening. Overall, many lessons learned from challenges to CRC screening can be applied to rapidly optimize HCC screening delivery.

An automated intervention with stepped increases in support to increase uptake of colorectal cancer screening: a randomized trial

BACKGROUND

Screening decreases colorectal cancer (CRC) incidence and mortality, yet almost half of age-eligible patients are not screened at recommended intervals.

OBJECTIVE

To determine whether interventions using electronic health records (EHRs), automated mailings, and stepped increases in support improve CRC screening adherence over 2 years.

DESIGN

4-group, parallel-design, randomized, controlled comparative effectiveness trial with concealed allocation and blinded outcome assessments. (ClinicalTrials.gov: NCT00697047)

SETTING

21 primary care medical centers.

PATIENTS

4675 adults aged 50 to 73 years not current for CRC screening.

INTERVENTION

Usual care, EHR-linked mailings ("automated"), automated plus telephone assistance ("assisted"), or automated and assisted plus nurse navigation to testing completion or refusal ("navigated"). Interventions were repeated in year 2.

MEASUREMENTS

The proportion of participants current for screening in both years, defined as colonoscopy or sigmoidoscopy (year 1) or fecal occult blood testing (FOBT) in year 1 and FOBT, colonoscopy, or sigmoidoscopy (year 2).

RESULTS

Compared with those in the usual care group, participants in the intervention groups were more likely to be current for CRC screening for both years with significant increases by intensity (usual care, 26.3% [95% CI, 23.4% to 29.2%]; automated, 50.8% [CI, 47.3% to 54.4%]; assisted, 57.5% [CI, 54.5% to 60.6%]; and navigated, 64.7% [CI, 62.5% to 67.0%]; P < 0.001 for all pair-wise comparisons). Increases in screening were primarily due to increased uptake of FOBT being completed in both years (usual care, 3.9% [CI, 2.8% to 5.1%]; automated, 27.5% [CI, 24.9% to 30.0%]; assisted, 30.5% [CI, 27.9% to 33.2%]; and navigated, 35.8% [CI, 33.1% to 38.6%]).

LIMITATION

Participants were required to provide verbal consent and were more likely to be white and to participate in other types of cancer screening, limiting generalizability.

CONCLUSION

Compared with usual care, a centralized, EHR-linked, mailed CRC screening program led to twice as many persons being current for screening over 2 years. Assisted and navigated interventions led to smaller but significant stepped increases compared with the automated intervention only. The rapid growth of EHRs provides opportunities for spreading this model broadly.

A randomized controlled trial of a tailored navigation and a standard intervention in colorectal cancer screening

BACKGROUND

This randomized, controlled trial assessed the impact of a tailored navigation intervention versus a standard mailed intervention on colorectal cancer screening adherence and screening decision stage (SDS).

METHODS

Primary care patients (n = 945) were surveyed and randomized to a Tailored Navigation Intervention (TNI) Group (n = 312), Standard Intervention (SI) Group (n = 316), or usual care CONTROL GROUP (n = 317). TNI Group participants were sent colonoscopy instructions and/or stool blood tests according to reported test preference, and received a navigation call. The SI Group was sent both colonoscopy instructions and stool blood tests. Multivariable analyses assessed intervention impact on adherence and change in SDS at 6 months.

RESULTS

The primary outcome, screening adherence (TNI Group: 38%, SI Group: 33%,

CONTROL GROUP

12%), was higher for intervention recipients than controls (P = 0.001 and P = 0.001, respectively), but the two intervention groups did not differ significantly (P = 0.201). Positive SDS change (TNI Group: +45%, SI Group: +37%, and

CONTROL GROUP

+23%) was significantly greater among intervention recipients than controls (P = 0.001 and P = 0.001, respectively), and the intervention group difference approached significance (P = 0.053). Secondary analyses indicate that tailored navigation boosted preferred test use, and suggest that intervention impact on adherence and SDS was attenuated by limited access to screening options.

CONCLUSIONS

Both interventions had significant, positive effects on outcomes compared with usual care. TNI versus SI impact had a modest positive impact on adherence and a pronounced effect on SDS.

IMPACT

Mailed screening tests can boost adherence. Research is needed to determine how preference, access, and navigation affect screening outcomes.

Effectiveness of multicultural health workers in chronic disease prevention and self-management in culturally and linguistically diverse populations: a systematic literature review

With a large and increasing culturally and linguistically diverse (CALD) population, the Australian health care system faces challenges in the provision of accessible culturally competent health care. Communities at higher risk of chronic disease include CALD communities. Overseas, multicultural health workers (MHWs) have been increasingly integrated in the delivery of culturally relevant primary health care to CALD communities. The objective of this systematic review was to examine the effectiveness of MHW interventions in chronic disease prevention and self-management in CALD populations with the aim to inform policy development of effective health care in CALD communities in Australia. A systematic review protocol was developed and computerised searches were conducted of multiple electronic databases from 1 January 1995 until 1 November 2010. Thirty-nine studies were identified including 31 randomised controlled trials. Many of the studies focussed on poor and underserved ethnic minorities. Several studies reported significant improvements in participants’ chronic disease prevention and self-management outcomes and meta-analyses identified a positive trend associated with MHW intervention. Australian Government policies express the need for targeted inventions for CALD communities. The broader systemic application of MHWs in Australian primary health care may provide one of the most useful targeted interventions for CALD communities.

Reducing inequalities in cancer outcomes: what works?

Despite efforts to reduce disparities in cancer outcomes among vulnerable populations, certain subgroups do not experience the gains made in the reduction of cancer incidence and mortality. In this article, we review recent trial data reporting on patient-, physician-, and system-centered interventions to improve quality and reduce disparities in cancer care spanning patient navigation to health reform. We conclude with data from a state that implemented a multitiered approach, targeting patient and systems barriers, that serves as a guide for future endeavors.

Patient navigation improves cancer diagnostic resolution: an individually randomized clinical trial in an underserved population

BACKGROUND

Barriers to timely resolution of abnormal cancer screening tests add to cancer health disparities among low-income, uninsured, and minority populations. We conducted a randomized trial to evaluate the impact of lay patient navigators on time to resolution and completion of follow-up testing among patients with abnormal screening tests in a medically underserved patient population.

METHODS

Denver Health, the safety-net health care system serving Denver, is one of 10 performance sites participating in the Patient Navigation Research Program. Of 993 eligible subjects with abnormal screening tests randomized to navigation and no-navigation (control) arms and analyzed, 628 had abnormal breast screens (66 abnormal clinical breast examinations, 304 BIRADS 0, 200 BIRADS 3, 58 BIRADS 4 or 5) whereas 235 had abnormal colorectal and 130 had abnormal prostate screens.

RESULTS

Time to resolution was significantly shorter in the navigated group (stratified log rank test, P < 0.001). Patient navigation improved diagnostic resolution for patients presenting with mammographic BIRADS 3 (P = 0.0003) and BIRADS 0 (P = 0.09), but not BIRADS 4/5 or abnormal breast examinations. Navigation shortened the time for both colorectal (P = 0.0017) and prostate screening resolution (P = 0.06). Participant demographics included 72% minority, 49% with annual household income less than $10,000, and 36% uninsured.

CONCLUSIONS

Patient navigation positively impacts time to resolution of abnormal screening tests for breast, colorectal, and prostate cancers in a medically underserved population.

IMPACT

By shortening the time to and increasing the proportion of patients with diagnostic resolution patient navigation could reduce disparities in stage at diagnosis and improve cancer outcomes.

Use of cancer control referrals by 2-1-1 callers: a randomized trial

BACKGROUND

Callers to 2-1-1 have greater need for and lesser use of cancer control services than other Americans. Integrating cancer risk assessment and referrals to preventive services into 2-1-1 systems is both feasible and acceptable to callers.

PURPOSE

To determine whether callers will act on these referrals.

METHODS

In a randomized trial, 2-1-1 callers (n=1200) received standard service and those with at least one cancer risk factor or need for screening were assigned to receive verbal referrals only, verbal referrals + a tailored reminder mailed to their home, or verbal referrals + a telephone health coach/navigator. All data were collected from June 2010 to March 2012 and analyzed in March and April 2012.

RESULTS

At 1-month follow-up, callers in the navigator condition were more likely to report having contacted a cancer control referral than those receiving tailored reminders or verbal referrals only (34% vs 24% vs 18%, respectively; n=772, p<0.0001). Compared to verbal referrals only, navigators were particularly effective in getting 2-1-1 callers to contact providers for mammograms (OR=2.10, 95% CI=1.04, 4.22); Paps (OR=2.98, 95% CI=1.18, 7.54); and smoking cessation (OR=2.07, 95% CI=1.14, 3.74).

CONCLUSIONS

Given the extensive reach of 2-1-1s and the elevated risk profile of their callers, even modest response rates could have meaningful impact on population health if proactive health referrals were implemented nationally.

Identifying barriers to colonoscopy screening for nonadherent African American participants in a patient navigation intervention

African Americans have a higher rate of colorectal cancer (CRC) mortality than other racial/ethnic groups. This disparity is alarming given that CRC is largely preventable through the use of endoscopy (screening colonoscopy or sigmoidoscopy), yet rates of CRC screening among African Americans is suboptimal. Only 48.9% of African Americans are screened for CRC through endoscopy or fecal occult blood testing. As such, researchers have focused their efforts on the prevention of CRC through patient navigation (PN) services for colonoscopy screening. Although PN has been successful in increasing colonoscopy screening rates, screening rates of navigated participants could still be improved. Thus, the purpose of this exploratory study was to understand why patients, who received PN services, did not complete a colonoscopy. Sixteen participants were interviewed to identify salient themes related to noncompletion of the colonoscopy procedure. Major themes identified included the following: a lack of knowledge about CRC; fear/anxiety about the procedure, including unknown expectations, fear of pain, and fear of cancer diagnosis; inadequate physician communication about CRC and the colonoscopy exam; and believing that cancer leads to death. Participants felt that greater communication and explanation from their physician might help allay their fears. Our findings also suggest that a universal approach to PN, even within culturally targeted interventions, may not be appropriate for all individuals. Future interventions should consider gender-specific navigation and combining PN with nonmedical interventions to address other identified barriers.

Circles of care: development and initial evaluation of a peer support model for African Americans with advanced cancer

Peer support interventions extend care and health information to underserved populations yet rarely address serious illness. Investigators from a well-defined academic-community partnership developed and evaluated a peer support intervention for African Americans facing advanced cancer. Evaluation methods used the Reach, Efficacy, Adoption, Implementation, Maintenance (RE-AIM) framework. Investigators initially recruited and trained 24 lay health advisors who shared information or support with 210 individuals. However, lay advisors reported barriers of medical privacy and lack of confidence working alone with people with cancer. Training was modified to match the support team model for peer support; training reached 193 volunteers, 104 of whom formed support teams for 47 persons with serious illness. Support teams were adopted by 23 community organizations, including 11 African American churches. Volunteers in teams felt prepared to implement many aspects of supportive care such as practical support (32%) or help with cancer or palliative care resources (43%). People with serious illness requested help with practical, emotional, spiritual, and quality of life needs; however, they rarely wanted advocacy (3%) or cancer or palliative care resources (5%) from support teams. Volunteers had difficulty limiting outreach to people with advanced cancer due to medical privacy concerns and awareness that others could benefit. Support teams are a promising model of peer support for African Americans facing advanced cancer and serious illness, with reach, adoption, and implementation superior to the lay advisor model. This formative initial evaluation provides evidence for feasibility and acceptance. Further research should examine the efficacy and potential for maintenance of this intervention.

Relationship between colorectal cancer screening adherence and knowledge among vulnerable rural residents of Appalachian Kentucky

BACKGROUND

Colorectal cancer (CRC) is 1 of the leading causes of cancer-related deaths among residents of rural Appalachia. Rates of guideline-consistent CRC screening in Appalachian Kentucky are suboptimal.

OBJECTIVE

This study sought to determine the relationship between CRC screening knowledge, specifically regarding recommended screening intervals, and receipt of screening among residents of rural Appalachian Kentucky.

METHODS

Residents of Appalachian Kentucky (n = 1096) between the ages of 50 and 76 years completed a telephone survey including questions on demographics, health history, and knowledge about CRC screening between November 20, 2009, and April 22, 2010.

RESULTS

Although 67% of respondents indicated receiving screenings according to guidelines, respondents also demonstrated significant knowledge deficiencies about screening recommendations. Nearly half of respondents were unable to identify the recommended screening frequency for any of the CRC screening modalities. Accuracy about the recommended frequency of screening was positively associated with screening adherence.

CONCLUSIONS

Enhanced educational approaches have the potential to increase CRC screening adherence in this population and reduce cancer mortality in this underserved region.

IMPLICATIONS FOR PRACTICE

Nurses play a critical role in patient education, which ultimately may increase screening rates. To fulfill this role, nurses should incorporate current recommendation about CRC screening into educational sessions. Advanced practices nurses in rural settings should also be aware of the increased vulnerability of their patient population and develop strategies to enhance awareness about CRC and the accompanying screening tests.

A cluster randomized trial evaluating the efficacy of patient navigation in improving quality of diagnostic care for patients with breast or colorectal cancer abnormalities

BACKGROUND

This study examines efficacy of a lay patient navigation (PN) program aimed to reduce time between a cancer abnormality and definitive diagnosis among racially/ethnically diverse and medically underserved populations of Tampa Bay, Florida.

METHODS

Using a cluster randomized design, the study consisted of 11 clinics (six navigated; five control). Patients were navigated from time of a breast or colorectal abnormality to diagnostic resolution, and to completion of cancer treatment. Using a generalized mixed-effects model to assess intervention effects, we examined: (i) length of time between abnormality and definitive diagnosis, and (ii) receipt of definitive diagnosis within the 6-month minimum follow-up period.

RESULTS

A total of 1,267 patients participated (588 navigated; 679 control). We also included data from an additional 309 chart abstractions (139 navigated arm; 170 control arm) that assessed outcomes at baseline. PN did not have a significant effect on time to diagnostic resolution in multivariable analysis that adjusted for race-ethnicity, language, insurance status, marital status, and cancer site (P = 0.16). Although more navigated patients achieved diagnostic resolution by 180 days, results were not statistically significant (74.5% navigated vs. 68.5% control, P = 0.07).

CONCLUSIONS

PN did not impact the overall time to completion of diagnostic care or the number of patients who reached diagnostic resolution of a cancer abnormality. Further evaluation of PN programs applied to other patient populations across the cancer continuum is necessary to gain a better perspective on its effectiveness.

IMPACT

PN programs may not impact timely resolution of an abnormality suspicious of breast or colorectal cancer.

A cluster randomized trial evaluating the efficacy of patient navigation in improving quality of diagnostic care for patients with breast or colorectal cancer abnormalities

BACKGROUND

This study examines efficacy of a lay patient navigation (PN) program aimed to reduce time between a cancer abnormality and definitive diagnosis among racially/ethnically diverse and medically underserved populations of Tampa Bay, Florida.

METHODS

Using a cluster randomized design, the study consisted of 11 clinics (six navigated; five control). Patients were navigated from time of a breast or colorectal abnormality to diagnostic resolution, and to completion of cancer treatment. Using a generalized mixed-effects model to assess intervention effects, we examined: (i) length of time between abnormality and definitive diagnosis, and (ii) receipt of definitive diagnosis within the 6-month minimum follow-up period.

RESULTS

A total of 1,267 patients participated (588 navigated; 679 control). We also included data from an additional 309 chart abstractions (139 navigated arm; 170 control arm) that assessed outcomes at baseline. PN did not have a significant effect on time to diagnostic resolution in multivariable analysis that adjusted for race-ethnicity, language, insurance status, marital status, and cancer site (P = 0.16). Although more navigated patients achieved diagnostic resolution by 180 days, results were not statistically significant (74.5% navigated vs. 68.5% control, P = 0.07).

CONCLUSIONS

PN did not impact the overall time to completion of diagnostic care or the number of patients who reached diagnostic resolution of a cancer abnormality. Further evaluation of PN programs applied to other patient populations across the cancer continuum is necessary to gain a better perspective on its effectiveness.

IMPACT

PN programs may not impact timely resolution of an abnormality suspicious of breast or colorectal cancer.

A multilevel research perspective on cancer care delivery: the example of follow-up to an abnormal mammogram

In 1999, researchers and policy makers recognized the challenge of creating an integrated patient-centered cancer care process across the many types of care from risk assessment through end of life. More than a decade later, there has been limited progress toward that goal even though the standard reductionist approach to health services and medical research has resulted in major advances in tests, procedures, and individualized patient approaches to care. In this commentary, we propose that considering an entire care process within its multilevel context may increase progress toward an integrated experience and improvements in the quality of care. As an illustrative case, we describe the multilevel context of care delivery for the process of follow-up to an abnormal screening mammogram. By taking a multilevel perspective on this process, we identify a rich set of options for intervening and improving follow-up to abnormalities and, therefore, outcomes of screening. We propose that taking this multilevel perspective when designing interventions may improve the quality of cancer care in an effective and sustainable way.

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.

Interventions to improve care related to colorectal cancer among racial and ethnic minorities: a systematic review

OBJECTIVE

To systematically review the literature to identify interventions that improve minority health related to colorectal cancer care.

DATA SOURCES

MEDLINE, PsycINFO, CINAHL, and Cochrane databases, from 1950 to 2010.

STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS

Interventions in US populations eligible for colorectal cancer screening, and composed of ≥50 % racial/ethnic minorities (or that included a specific sub-analysis by race/ethnicity). All included studies were linked to an identifiable healthcare source. The three authors independently reviewed the abstracts of all the articles and a final list was determined by consensus. All papers were independently reviewed and quality scores were calculated and assigned using the Downs and Black checklist.

RESULTS

Thirty-three studies were included in our final analysis. Patient education involving phone or in-person contact combined with navigation can lead to modest improvements, on the order of 15 percentage points, in colorectal cancer screening rates in minority populations. Provider-directed multi-modal interventions composed of education sessions and reminders, as well as pure educational interventions were found to be effective in raising colorectal cancer screening rates, also on the order of 10 to 15 percentage points. No relevant interventions focusing on post-screening follow up, treatment adherence and survivorship were identified.

LIMITATIONS

This review excluded any intervention studies that were not tied to an identifiable healthcare source. The minority populations in most studies reviewed were predominantly Hispanic and African American, limiting generalizability to other ethnic and minority populations.

CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS

Tailored patient education combined with patient navigation services, and physician training in communicating with patients of low health literacy, can modestly improve adherence to CRC screening. The onus is now on researchers to continue to evaluate and refine these interventions and begin to expand them to the entire colon cancer care continuum.

Cost analysis of a patient navigation system to increase screening colonoscopy adherence among urban minorities

BACKGROUND

Patient navigation (PN) is being used increasingly to help patients complete screening colonoscopy (SC) to prevent colorectal cancer. At their large, urban academic medical center with an open-access endoscopy system, the authors previously demonstrated that PN programs produced a colonoscopy completion rate of 78.5% in a cohort of 503 patients (predominantly African Americans and Latinos with public health insurance). Very little is known about the direct costs of implementing PN programs. The objective of the current study was to perform a detailed cost analysis of PN programs at the authors' institution from an institutional perspective.

METHODS

In 2 randomized controlled trials, average-risk patients who were referred for SC by primary care providers were recruited for PN between May 2008 and May 2010. Patients were randomized to 1 of 4 PN groups. The cost of PN and net income to the institution were determined in a cost analysis.

RESULTS

Among 395 patients who completed colonoscopy, 53.4% underwent SC alone, 30.1% underwent colonoscopy with biopsy, and 16.5% underwent snare polypectomy. Accounting for the average contribution margins of each procedure type, the total revenue was $95,266.00. The total cost of PN was $14,027.30. Net income was $81,238.70. In a model sample of 1000 patients, net incomes for the institutional completion rate (approximately 80%), the historic PN program (approximately 65%), and the national average (approximately 50%) were compared. The current PN program generated additional net incomes of $35,035.50 and $44,956.00, respectively.

CONCLUSIONS

PN among minority patients with mostly public health insurance generated additional income to the institution, mainly because of increased colonoscopy completion rates.

Impact of navigators on completion of steps in the kidney transplant process: a randomized, controlled trial

BACKGROUND AND OBJECTIVES

Many patients with ESRD, particularly minorities and women, face barriers in completing the steps required to obtain a transplant. These eight sequential steps are as follows: medical suitability, interest in transplant, referral to a transplant center, first visit to center, transplant workup, successful candidate, waiting list or identify living donor, and receive transplant. This study sought to determine the effect of navigators on completion of steps.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Cluster randomized, controlled trial at 23 Ohio hemodialysis facilities. One hundred sixty-seven patients were recruited between January 2009 and August 2009 and were followed for up to 24 months or until study end in February 2011. Trained kidney transplant recipients met monthly with intervention participants (n=92), determined their step in the transplant process, and provided tailored information and assistance in completing the step. Control participants (n=75) continued to receive usual care. The primary outcome was the number of transplant process steps completed.

RESULTS

Starting step did not significantly differ between the two groups. By the end of the trial, intervention participants completed more than twice as many steps as control participants (3.5 versus 1.6 steps; difference, 1.9 steps; 95% confidence interval, 1.3-2.5 steps). The effect of the intervention on step completion was similar across race and sex subgroups.

CONCLUSIONS

Use of trained transplant recipients as navigators resulted in increased completion of transplant process steps.

Testing a Spanish-language colorectal cancer screening decision aid in Latinos with limited English proficiency: results from a pre-post trial and four month follow-up survey

BACKGROUND

Compared with non-Latinos, Latinos in the US have low rates of colorectal cancer (CRC) screening and low rates of knowledge regarding CRC screening tests and guidelines. Spanish speaking Latinos have particularly low CRC screening rates and screening knowledge. Our purpose was twofold: (1) to evaluate the effect of a computer-based, Spanish-language CRC screening decision aid on screening knowledge, intent to obtain screening, and screening self-efficacy in a community sample of Latinos with limited English proficiency (LEP); and (2) to survey these decision aid viewers at four months to determine their rates of CRC discussions with a health care provider as well as their rates of screening test completion.

METHODS

We recruited 50-75 year old Latinos with LEP who were not current with CRC. Participants screening viewed a 14 minute multimedia decision aid that addresses CRC screening rationale, recommendations, and options. We conducted an uncontrolled (pre-post) study in which we assessed screening knowledge, self-efficacy, and intent at baseline and immediately after decision aid viewing. We also conducted a follow-up telephone survey of participants at four months to examine rates of patient-provider screening discussions and test completion.

RESULTS

Among n = 80 participants, knowledge scores increased from 20% (before) to 72% (after) decision aid viewing (absolute difference [95%CI]: 52% [46, 59]). The proportion with high screening self-efficacy increased from 67% to 92% (25% [13, 37]); the proportion with high screening intent increased from 63% to 95% (32% [21, 44]). We reached 68 (85%) of 80 participants eligible for the follow-up survey. Of these 36 (53%) reported discussing screening with a provider and 13 (19%) completed a test.

CONCLUSION

Viewing a Spanish-language decision aid increased CRC screening knowledge, self-efficacy, and intent among Latinos with LEP. Decision aid viewing appeared to promote both CRC screening discussions with health care providers and test completion. The decision aid may be an effective tool for promoting CRC screening and reducing screening disparities in this population.

Native cancer navigation: the state of the science

The purpose of this literature review is to determine the current state of the science for the effectiveness of patient navigation on improving outcomes of cancer care across the continuum among Native Americans. The research will help healthcare professionals ascertain potential evidence-based practice guidelines and gaps in knowledge, which may provide direction for future research. Data synthesis included the use of Native navigation for cancer care, which has been demonstrated in limited, nonrandomized studies to improve cancer knowledge, access to care, and quality of life for Native Americans. Those studies had limitations, including small sample size, self-report of outcome measures, and lack of randomization. Evidence is insufficient to conclude that the use of Native navigation is superior to usual cancer care for Native American patients. Oncology nurses have a role in training personnel to serve as cancer navigators. Nurses need to be supportive of culturally appropriate navigation programs and know about services provided by navigators. In addition, nurse educators need to encourage Native Americans in their communities to consider choosing nursing as a profession. If an oncology nurse has an interest in research, opportunities exist to assist with or conduct research projects regarding Native cancer navigation. A particular need exists for addressing the gaps in research identified in this article.

The economic impact of a patient navigator program to increase screening colonoscopy

BACKGROUND

Patient navigation can increase colorectal cancer screening rates. The net economic impact of a colonoscopy patient navigator program was evaluated in an urban public hospital setting.

METHODS

Cost, cost-effectiveness, and cost-benefit analyses were performed of a colonoscopy patient navigation program at 3 urban public hospitals in the period from 2003 to 2007. Program effectiveness was assessed in a 2-group, pre- and post-program, nonrandomized evaluation, comparing program hospitals with comparison hospitals that served similar populations. Costs were assessed from the provider's perspective. Outcomes included colonoscopy volume, colonoscopy completion rate, program cost, incremental cost-effectiveness, and net monetary benefit.

RESULTS

Patient navigation was associated with a 61% increase in average monthly colonoscopy volume at program hospitals, from 114 procedures to 184 procedures, compared with a 12% increase at comparison hospitals. Adjusted for other factors, the navigator program increased colonoscopy volume by 44 to 67 additional procedures per month. Average program cost varied from $50 to $300 per patient referred to a navigator. Incremental cost-effectiveness varied from $200 to $700 per additional colonoscopy. At 2 hospitals, net revenue associated with increased colonoscopy volume exceeded the program cost per additional colonoscopy, yielding a net financial benefit; at the third hospital, the program yielded a net cost. Variation between hospitals in the program's economic impact was primarily attributable to differences in personnel costs.

CONCLUSIONS

Economic evaluation of this colonoscopy patient navigator program in an urban public hospital setting suggests that such programs can be a cost-effective use of limited resources and yield a net financial benefit for providers.

Interventions to improve patient participation in the treatment process for culturally and linguistically diverse people with cancer: a systematic review

Disparities in cancer outcomes for people from culturally and linguistically diverse (CALD) groups are well known. Improving CALD patients' active participation in treatment processes holds potential to improve outcomes, but little is known of effective strategies to facilitate this. This systematic review investigated interventions to improve three aspects of participation in cancer care among CALD groups, namely involvement in decision-making, communication with health providers and treatment adherence. A comprehensive search of electronic bibliographic databases was conducted to identify intervention studies that reported outcomes relevant to patient participation for CALD groups. Two reviewers independently critically appraised the studies and abstracted data. Of 10,278 potential articles, seven met the inclusion criteria, including three randomized controlled, three non-randomized and one mixed-method experimental studies. Interventions included the use of patient navigators, videos and decision aids. The impact on patient participation was varied. The effect of a decision aid and patient navigator interventions on communication with health providers was positive. While the use of a decisions aid successfully facilitated shared decision-making and patients' perception of treatment adherence, the use of patient navigators was ineffective. A computer support system was found to improve general patient participation; however little clarification of what this involved was provided. This systematic review identified few rigorous evaluations of interventions to improve treatment participation for CALD people with cancer, highlighting the lack of a robust evidence base to improve this crucial aspect of care. The development and evaluation of interventions for diverse populations remains a priority.

Feasibility of chronic disease patient navigation in an urban primary care practice

The purpose of this study was to evaluate the feasibility of incorporating chronic disease navigation using lay health care workers trained in motivational interviewing (MI) into an existing mammography navigation program. Primary-care patient navigators implemented MI-based telephone conversations around mammography, smoking, depression, and obesity. We conducted a small-scale demonstration, using mixed methods to assess patient outcomes and provider satisfaction. One hundred nine patients participated. Ninety-four percent scheduled and 73% completed a mammography appointment. Seventy-one percent agreed to schedule a primary care appointment and 54% completed that appointment. Patients and providers responded positively. Incorporating telephone-based chronic disease navigation supported by MI into existing disease-specific navigation is efficacious and acceptable to those enrolled.

The last frontier: innovative efforts to reduce colorectal cancer disparities among the remote Alaska Native population

BACKGROUND

The Alaska Native (AN) population experiences twice the incidence and mortality of colorectal cancer (CRC) as does the U.S. white population. CRC screening allows early detection and prevention of cancer.

OBJECTIVE

We describe pilot projects conducted from 2005 to 2010 to increase CRC screening rates among AN populations living in rural and remote Alaska.

DESIGN

Projects included training rural mid-level providers in flexible sigmoidoscopy, provision of itinerant endoscopy services at rural tribal health facilities, the creation and use of a CRC first-degree relative database to identify and screen individuals at increased risk, and support and implementation of screening navigator services.

SETTING

Alaska Tribal Health System.

PATIENTS

AN population.

INTERVENTIONS

Itinerant endoscopy, patient navigation.

MAIN OUTCOME MEASUREMENTS

AN patients screened for CRC, colonoscopy quality measures.

RESULTS

As a result of these ongoing efforts, statewide AN CRC screening rates increased from 29% in 2000 to 41% in 2005 before the initiation of these projects and increased to 55% in 2010. The provision of itinerant CRC screening clinics increased rural screening rates, as did outreach to average-risk and increased-risk (family history) ANs by patient navigators. However, health care system barriers were identified as major obstacles to screening completion, even in the presence of dedicated patient navigators.

LIMITATIONS

Continuing challenges include geography, limited health system capacity, high staff turnover, and difficulty getting patients to screening appointments.

CONCLUSIONS

The projects described here aimed to increase CRC screening rates in an innovative and sustainable fashion. The issues and solutions described may provide insight for others working to increase screening rates among geographically dispersed and diverse populations.

Qualitative analysis of peer coaches' experiences with counseling African Americans about reducing heart disease risk

BACKGROUND

Despite mounting evidence that peer coaches can make significant contributions to patient health, little is known about factors that must be addressed to engage and retain them in their role.

OBJECTIVE

To identify motivators and barriers to serving as a peer coach.

DESIGN

Open ended semi-structured interviews.

PARTICIPANTS AND SETTING

In a randomized trial of peer support, patients with well controlled hypertension and good interpersonal skills were recruited and trained to serve as peer coaches for African-American patients from the same practices who had poorly controlled hypertension. Peer coaches spoke by telephone at least three times with their same sex patient-clients on alternate months during the 6-month intervention and counseled about medication adherence as well as other healthy lifestyles.

KEY RESULTS

Of 15 trained peer coaches, ten were contacted and agreed to participate in the qualitative interview. Peer coaches had a mean age of 66 years, 50% were women, and 80% were African-American. Themes regarding favorable aspects of the peer coach experience included: meaning and satisfaction derived from contributing to community health and the personal emotional and physical benefits derived from serving as a peer coach. Negative aspects centered on: challenges in establishing the initial telephone contact and wanting more information about their patient-clients' personal health conditions and status. Peer coaches endorsed gender matching but were less clear about race-matching.

CONCLUSIONS

Programs that utilize peer support to enhance positive health behaviors should recognize that a spirit of volunteerism motivates many successful peer coaches. Program planners should acknowledge the special characteristics required of successful peer coaches when selecting, motivating and training individuals for this role.

Closing the gap: eliminating health care disparities among Latinos with diabetes using health information technology tools and patient navigators

Latinos have higher rates of diabetes and diabetes-related complications compared to non-Latinos. Clinical diabetes self-management tools that rely on innovative health information technology (HIT) may not be widely used by Latinos, particularly those that have low literacy or numeracy, low income, and/or limited English proficiency. Prior work has shown that tailored diabetes self-management educational interventions are feasible and effective in improving diabetes knowledge and physiological measures among Latinos, especially those interventions that utilize tailored coaching and navigator programs. In this article, we discuss the role of HIT for diabetes management in Latinos and describe a novel "eNavigator" role that we are developing to increase HIT adoption and thereby reduce health care disparities.

A multimodal intervention to promote mammography and colorectal cancer screening in a safety-net practice

BACKGROUND

There are limited data regarding interventions designed to improve cancer screening rates in safety-net practices with "real world" patients.

OBJECTIVE

To examine the impact of a multimodal intervention on mammography and colorectal cancer (CRC) screening rates in a safety-net practice caring for underserved patients.

METHODS

At an inner-city family medicine practice, all patients past due for mammography or CRC screening were assigned to receive or not receive a screening promotion intervention based on their medical record number. The 12-month intervention included outreach to patients (tailored letters, automated and personal phone calls) and point-of-care patient and clinician prompts. The trial was registered at clinicaltrials.gov, NCT00818857.

RESULTS

We enrolled 469 participants aged 40 to 74 years, including 28% African Americans, 5% Latinos, 25% with Medicaid, and 10% without any form of insurance. Participants in the intervention group showed statistically significantly higher rates of cancer screening; rates were 41% vs 16.8% for mammography and 28.8% vs 10% for CRC screening. These findings were confirmed in multivariable analysis. Similar relative improvements in screening were seen across race, ethnicity, socioeconomic status, and insurance groups.

DISCUSSION

A multimodal intervention shows promise for improving rates of mammography and colorectal cancer screening within a safety-net practice. Further study will identify the most cost-effective components of the intervention.

Innovative approaches to reducing cancer health disparities: the Moffitt Cancer Center Patient Navigator Research Program

The Moffitt Cancer Center Patient Navigation Research Program (Moffitt PNRP) is evaluating the efficacy of patient navigation in reducing delays from screening abnormality to diagnostic resolution of a breast or colorectal abnormality. The Moffitt PNRP was conducted in three phases: (1) developing an acceptable, appealing, and culturally appropriate patient navigation program; (2) conducting a group randomized controlled trial to evaluate the patient navigation program; and (3) disseminating research findings and Moffitt PNRP intervention model. The patient navigation program was developed through significant formative research, input from the Moffitt PNRP Community Advisory Board, and through a close collaboration with the Tampa Bay Community Cancer Network. 1367 patients were enrolled in the Phase 2 group randomized trial of the Moffitt PNRP. Most Moffitt PNRP group randomized trial participants are Hispanic, female, and Spanish speaking, with minimal education and income. Analyses are currently being conducted to evaluate efficacy of the Moffitt PNRP.

Bridging the digital divide in health care: the role of health information technology in addressing racial and ethnic disparities

BACKGROUND

Racial and ethnic disparities in health care have been consistently documented in the diagnosis, treatment, and outcomes of many common clinical conditions. There has been an acceleration of health information technology (HIT) implementation in the United States, with health care reform legislation including multiple provisions for collecting and using health information to improve and monitor quality and efficiency in health care. Despite an uneven and generally low level of implementation, research has demonstrated that HIT has the potential to improve quality of care and patient safety. If carefully designed and implemented, HIT also has the potential to eliminate disparities.

HIT AND DISPARITIES

Several root causes for disparities are amenable to interventions using HIT, particularly innovations in electronic health records, as well as strategies for chronic disease management. Recommendations regardinghealth care system, provider, and patient factors can help health care organizations address disparities as they adopt, expand, and tailor their HIT systems. In terms of health care system factors, organizations should (1) automate and standardize the collection of race/ethnicity and language data, (2) prioritize the use of the data for identifying disparities and tailoring improvement efforts, (3) focus HIT efforts to address fragmented care delivery for racial/ethnic minorities and limited-English-proficiency patients, (4) develop focused computerized clinical decision support systems for clinical areas with significant disparities, and (5) include input from racial/ethnic minorities and those with limited English proficiency in developing patient HIT tools to address the digital divide.

CONCLUSIONS

As investments are made in HIT, consideration must be given to the impact that these innovations have on the quality and cost of health care for all patients, including those who experience disparities.

Reducing cardiovascular disease risk using patient navigators, Denver, Colorado, 2007-2009

INTRODUCTION

Early identification of cardiovascular disease (CVD) risk is important to reach people in need of treatment. At-risk patients benefit from behavioral counseling in addition to medical therapy. The objective of this study was to determine whether enhanced counseling, using patient navigators trained to counsel patients on CVD risk-reduction strategies and facilitate patient access to community-based lifestyle-change services, reduced CVD risk among at-risk patients in a low-income population.

METHODS

We compared clinical characteristics at baseline and 12-month follow-up among 340 intervention and 340 comparison patients from community health centers in Denver, Colorado, between March 2007 and June 2009; all patients had a Framingham risk score (FRS) greater or equal to 10% at baseline. The intervention consisted of patient-centered counseling by bilingual patient navigators. At baseline and at 6-month and 12-month follow-up, we assessed health behaviors of intervention participants. We used an intent-to-treat approach for all analyses and measured significant differences by χ(2) and t tests.

RESULTS

We found significant differences in several clinical outcomes. At follow-up, the mean FRS was lower for the intervention group (mean FRS, 15%) than for the comparison group (mean FRS, 16%); total cholesterol was lower for the intervention group (mean total cholesterol, 183 mg/dL) than for the comparison group (mean total cholesterol, 197 mg/dL). Intervention participants reported significant improvements in some health behaviors at 12-month follow-up, especially nutrition-related behaviors. Behaviors related to tobacco use and cessation attempts did not improve.

CONCLUSION

Patient navigators may provide some benefit in reducing risk of CVD in a similar population.

Unequal treatment in the US: lessons and recommendations for cancer care internationally

Despite interventions that have improved the overall health of the majority of Americans, racial and ethnic minorities have benefited less from these advances. Research has shown that multiple factors contribute to racial and ethnic disparities in health, health care, and cancer care. The Institute of Medicine Report, "Unequal Treatment" provides a detailed examination of racial/ethnic disparities in health care in the U.S., highlighting three clinical contributors--poor provider-patient communication, stereotyping in clinical decisionmaking, and patient mistrust. Although the findings and recommendations in "Unequal Treatment" are broad in scope, they provide a blueprint for how to address disparities in health care in general-as well as cancer care-and have direct implications for clinical practice, both nationally and internationally. We propose a patient-based approach to cross-cultural care as a model to improve communication with racial and ethnic minorities, and cross-cultural populations in general. We also highlight the importance of community based interventions, such as those that use health care navigators to promote cancer screening. If we hope to provide effective cancer care around the world, we must be attentive to the factors that impact minorities and vulnerable populations, and be prepared to address them.

Effective interventions to facilitate the uptake of breast, cervical and colorectal cancer screening: an implementation guideline

BACKGROUND

Appropriate screening may reduce the mortality and morbidity of colorectal, breast, and cervical cancers. Several high-quality systematic reviews and practice guidelines exist to inform the most effective screening options. However, effective implementation strategies are warranted if the full benefits of screening are to be realized. We developed an implementation guideline to answer the question: What interventions have been shown to increase the uptake of cancer screening by individuals, specifically for breast, cervical, and colorectal cancers?

METHODS

A guideline panel was established as part of Cancer Care Ontario's Program in Evidence-based Care, and a systematic review of the published literature was conducted. It yielded three foundational systematic reviews and an existing guidance document. We conducted updates of these reviews and searched the literature published between 2004 and 2010. A draft guideline was written that went through two rounds of review. Revisions were made resulting in a final set of guideline recommendations.

RESULTS

Sixty-six new studies reflecting 74 comparisons met eligibility criteria. They were generally of poor to moderate quality. Using these and the foundational documents, the panel developed a draft guideline. The draft report was well received in the two rounds of review with mean quality scores above four (on a five-point scale) for each of the items. For most of the interventions considered, there was insufficient evidence to support or refute their effectiveness. However, client reminders, reduction of structural barriers, and provision of provider assessment and feedback were recommended interventions to increase screening for at least two of three cancer sites studied. The final guidelines also provide advice on how the recommendations can be used and future areas for research.

CONCLUSION

Using established guideline development methodologies and the AGREE II as our methodological frameworks, we developed an implementation guideline to advise on interventions to increase the rate of breast, cervical and colorectal cancer screening. While advancements have been made in these areas of implementation science, more investigations are warranted.

What implementation interventions increase cancer screening rates? a systematic review

BACKGROUND

Appropriate screening may reduce the mortality and morbidity of colorectal, breast, and cervical cancers. However, effective implementation strategies are warranted if the full benefits of screening are to be realized. As part of a larger agenda to create an implementation guideline, we conducted a systematic review to evaluate interventions designed to increase the rate of breast, cervical, and colorectal cancer (CRC) screening. The interventions considered were: client reminders, client incentives, mass media, small media, group education, one-on-one education, reduction in structural barriers, reduction in out-of-pocket costs, provider assessment and feedback interventions, and provider incentives. Our primary outcome, screening completion, was calculated as the overall median post-intervention absolute percentage point (PP) change in completed screening tests.

METHODS

Our first step was to conduct an iterative scoping review in the research area. This yielded three relevant high-quality systematic reviews. Serving as our evidentiary foundation, we conducted a formal update. Randomized controlled trials and cluster randomized controlled trials, published between 2004 and 2010, were searched in MEDLINE, EMBASE and PSYCHinfo.

RESULTS

The update yielded 66 studies new eligible studies with 74 comparisons. The new studies ranged considerably in quality. Client reminders, small media, and provider audit and feedback appear to be effective interventions to increase the uptake of screening for three cancers. One-on-one education and reduction of structural barriers also appears effective, but their roles with CRC and cervical screening, respectively, are less established. More study is required to assess client incentives, mass media, group education, reduction of out-of-pocket costs, and provider incentive interventions.

CONCLUSION

The new evidence generally aligns with the evidence and conclusions from the original systematic reviews. This review served as the evidentiary foundation for an implementation guideline. Poor reporting, lack of precision and consistency in defining operational elements, and insufficient consideration of context and differences among populations are areas for additional research.

Feasibility and efficacy of pairing fecal immunochemical testing with mammography for increasing colorectal cancer screening among uninsured Latinas in northern Manhattan

OBJECTIVES

We evaluated the feasibility and efficacy of a program to promote colorectal cancer screening (CRC) among uninsured Latinas receiving mammography through a cancer screening clinic in northern Manhattan.

METHODS

Between August 2009 and March 2010, unscreened, average CRC risk, uninsured Latinas, aged 50-64 years, undergoing mammography received a screening recommendation, education, and fecal immunochemical test (FIT). Socio-demographic information and level of acculturation was collected. Screening compliance was assessed.

RESULTS

Of 651 Latinas evaluated, 210 were eligible and, of these, 94% (n=197) consented to participate; 441 were excluded because they were up-to-date with CRC screening (n=130), < 50 (n=285) or >64 (n=26) years of age. After intervention, 177 (90%) completed FIT. Within 2 weeks, 87% completed the FIT, and 69% did so with no reminder calls. Acculturation was significantly lower among screeners (p=0.014). Compared with non-screeners, screeners were more likely to be foreign-born (p=0.009), to speak only Spanish (p=0.043), and to prefer to read (p=0.037), and think (p=0.015) in Spanish.

CONCLUSION

This study suggests that pairing CRC education and screening with mammography is both feasible and efficacious.

Assessing the impact of patient navigation: prevention and early detection metrics

BACKGROUND

The lack of comparable metrics to evaluate prevention and early detection patient navigation programs impeded the ability to identify best practices.

METHODS

The Prevention and Early Detection Workgroup of the Patient Navigation Leadership Summit was charged with making recommendations for common clinical metrics specific to the prevention and early detection phase of the cancer care continuum. The workgroup began with a review of existing literature to characterize variability in published navigation metrics; then developed a list of priority recommendations that would be applicable to the range of navigation settings (clinical, academic, or community-based).

RESULTS

Recommendations for researchers and program evaluators included the following: 1) Clearly document key program characteristics; 2) Use a set of core data elements to form the basis of your reported metrics; and 3) Prioritize data collection using methods with the least amount of bias.

CONCLUSIONS

If navigation programs explicitly state the context of their evaluation and choose from among the common set of data elements, meaningful comparisons among existing programs should be feasible.

Patient navigation: an update on the state of the science

Although patient navigation was introduced 2 decades ago, there remains a lack of consensus regarding its definition, the necessary qualifications of patient navigators, and its impact on the continuum of cancer care. This review provides an update to the 2008 review by Wells et al on patient navigation. Since then, there has been a significant increase in the number of published studies dealing with cancer patient navigation. The authors of the current review conducted a search by using the keywords "navigation" or "navigator" and "cancer." Thirty-three articles published from November 2007 through July 2010 met the search criteria. Consistent with the prior review, there is building evidence of some degree of efficacy of patient navigation in terms of increasing cancer screening rates. However, there is less recent evidence concerning the benefit of patient navigation with regard to diagnostic follow-up and in the treatment setting, and a paucity of research focusing on patient navigation in cancer survivorship remains. Methodological limitations were noted in many studies, including small sample sizes and a lack of control groups. As patient navigation programs continue to develop across North America and beyond, further research will be required to determine the efficacy of cancer patient navigation across all aspects of the cancer care continuum.
