Patient navigation is an evidence-based intervention involving trained healthcare workers who assist patients in assessing and mitigating personal and environmental factors to promote healthy behaviors. The purpose of this research is to systematically assess the efficacy of patient navigation and similar programs to improve diagnosis and treatment of diseases affecting medically underserved populations. A systematic review was performed by searching PubMed, MEDLINE, PsychINFO, and CINAHL to identify potential studies. Eligible studies were those containing original peer-reviewed research reports in English on patient navigation, community health workers, vulnerable and underserved populations, and healthcare disparity. Specific outcomes regarding patient navigator including the effect of the intervention on definitive diagnosis and effect on initiation of treatment were extracted from each study. The search produced 1428 articles, and 16 were included for review. All studies involved patient navigation in the field of oncology in underserved populations. Timing of initial contact with a patient navigator after diagnostic or screening testing is correlated to the effectiveness of the navigator intervention. The majority of the studies reported significantly shorter time intervals to diagnosis and to treatment with patient navigation. Patient navigation expedites oncologic diagnosis and treatment of patients in underserved populations. This intervention is more efficacious when utilized shortly after screening or diagnostic testing.  相似文献

Published studies regarding patient navigation (PN) and cancer were reviewed to assess quality, determine gaps, and identify avenues for future research. The PubMed and EMBASE databases were searched for studies investigating the efficacy and cost-effectiveness of PN across the cancer continuum. Each included article was scored independently by 2 separate reviewers with the Quality Assessment Tool for Quantitative Studies. The current review identified 113 published articles that assessed PN and cancer care, between August 1, 2010, and February 1, 2018, 14 of which reported on the cost-effectiveness of PN programs. Most publications focused on the effectiveness of PN in screening (50%) and diagnosis (27%) along the continuum of cancer care. Many described the effectiveness of PN for breast cancer (52%) or colorectal cancer outcomes (51%). Most studies reported favorable outcomes for PN programs, including increased uptake of and adherence to cancer screenings, timely diagnostic resolution and follow-up, higher completion rates for cancer therapy, and higher rates of attending medical appointments. Cost-effectiveness studies showed that PN programs yielded financial benefits. Quality assessment showed that 75 of the 113 included articles (65%) had 2 or more weak components. In conclusion, this review indicates numerous gaps within the PN and cancer literature where improvement is needed. For example, more research is needed at other points along the continuum of cancer care outside of screening and diagnosis. In addition, future research into the effectiveness of PN for understudied cancers outside of breast and colorectal cancer is necessary along with an assessment of cost-effectiveness and more rigorous reporting of study designs and results in published articles.  相似文献

Patient navigation is a strategy for overcoming barriers to reduce disparities and to improve access and outcomes. The aim of this umbrella review was to identify, critically appraise, synthesize, and present the best available evidence to inform policy and planning regarding patient navigation across the cancer continuum. Systematic reviews examining navigation in cancer care were identified in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), Epistemonikos, and Prospective Register of Systematic Reviews (PROSPERO) databases and in the gray literature from January 1, 2012, to April 19, 2022. Data were screened, extracted, and appraised independently by two authors. The JBI Critical Appraisal Checklist for Systematic Review and Research Syntheses was used for quality appraisal. Emerging literature up to May 25, 2022, was also explored to capture primary research published beyond the coverage of included systematic reviews. Of the 2062 unique records identified, 61 systematic reviews were included. Fifty-four reviews were quantitative or mixed-methods reviews, reporting on the effectiveness of cancer patient navigation, including 12 reviews reporting costs or cost-effectiveness outcomes. Seven qualitative reviews explored navigation needs, barriers, and experiences. In addition, 53 primary studies published since 2021 were included. Patient navigation is effective in improving participation in cancer screening and reducing the time from screening to diagnosis and from diagnosis to treatment initiation. Emerging evidence suggests that patient navigation improves quality of life and patient satisfaction with care in the survivorship phase and reduces hospital readmission in the active treatment and survivorship care phases. Palliative care data were extremely limited. Economic evaluations from the United States suggest the potential cost-effectiveness of navigation in screening programs.  相似文献

BACKGROUND: Logistic, cultural, educational, and other barriers can impede the delivery of high-quality cancer care to underserved patients. Patient navigation services represent one innovation for addressing perceived barriers to care encountered by disadvantaged patients. In this report, the authors have 1) defined patient navigation, distinguishing it from other cancer support services; 2) described how programs are organized; and 3) discussed the need for research on program effectiveness. METHODS: Information was examined on navigation programs published in the scientific literature and on line. Qualitative research also was conducted, consisting of direct observation of patient care in cancer clinics with and without navigators in northern California, in-person interviews with personnel and patients in the clinics observed, and telephone interviews with navigators at four sites across the United States. RESULTS: The authors found that navigation services have been implemented at all stages of cancer care: prevention, screening, treatment, and survival. Navigators differ from other cancer support personnel in their orientation toward flexible problem solving to overcome perceived barriers to care rather than the provision of a predefined set of services. There are no rigorous demonstrations of the effects and effectiveness of navigation, although such studies are underway. CONCLUSIONS: Currently, patient navigation is understudied, and literature documenting its effects and effectiveness is scant. Rigorous studies are needed of the navigator role and program costs and benefits. Such studies will facilitate an assessment of program effectiveness, feasibility across a range of health care settings, and performance relative to alternative approaches for addressing barriers to care among the underserved.  相似文献

BACKGROUND:

The Ralph Lauren Cancer Center implemented patient navigation programs in sites across the United States building on the model pioneered by Harold P. Freeman, MD. Patient navigation targets medically underserved with the objective of reducing the time interval between an abnormal cancer finding, diagnostic resolution, and treatment initiation. In this study, the authors assessed the incremental cost effectiveness of adding patient navigation to standard cancer care in 3 community hospitals in the United States.

METHODS:

A decision‐analytic model was used to assess the cost effectiveness of a colorectal and breast cancer patient navigation program over the period of 1 year compared with standard care. Data sources included published estimates in the literature and primary costs, aggregate patient demographics, and outcome data from 3 patient navigation programs.

RESULTS:

After 1 year, compared with standard care alone, it was estimated that offering patient navigation with standard care would allow an additional 78 of 959 individuals with an abnormal breast cancer screening and an additional 21 of 411 individuals with abnormal colonoscopies to reach timely diagnostic resolution. Without including medical treatment costs saved, the cost‐effectiveness ratio ranged from $511 to $2080 per breast cancer diagnostic resolution achieved and from $1192 to $9708 per colorectal cancer diagnostic resolution achieved.

CONCLUSIONS:

The current results indicated that implementing breast or colorectal cancer patient navigation in community hospital settings in which low‐income populations are served may be a cost‐effective addition to standard cancer care in the United States.

Objective: The purpose of this systematic review is to broaden our knowledge of colorectal cancer (CRC) screening in South Asian immigrants living in Canada, Hong Kong, the United Kingdom, the United States, and Australia by determining the barriers and facilitators and examining interventions for CRC screening. Methods: A literature search of PubMed, Ovid Medline, and Google was conducted using South Asian, Asian Indians, cancer screening, colorectal neoplasm, early detection of cancer, and mass screening as search terms. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Only research articles written in English from 2000 to July 2022 were collected. Inclusion criteria included all English-language articles, the South Asian population, and either reporting barriers, facilitators, interventions, or recommendations for CRC screening. Exclusion criteria included all articles that did not meet inclusion criteria or were duplicates. A total of 32 articles were deemed eligible for inclusion and were retrieved for further analysis. The countries of origin in the articles reviewed included Canada, Hong Kong, the United Kingdom, the United States, and Australia. Results: In general, the studies indicated that South Asians have low CRC screening rates. The most common barriers reported were poor knowledge/awareness of CRC and CRC screening, lack of physician recommendation, psychological factors (e.g., fear, anxiety, and shame), cultural/religious factors, and sociodemographic factors (language barrier, lower income, and female gender). The most important facilitator reported was the physician’s recommendation. Six intervention studies of either education or organized screening programs were shown to have a positive influence by increasing knowledge and improving attitudes toward CRC screening. Conclusion: Of the limited number of studies identified, the population categorized as South Asians was largely heterogeneous, including a diversity of ethnicities. Although the rates of CRC among South Asians were relatively low, there remain many cultural barriers to the awareness of and screening for CRC in this population. Further research in this population is needed to better identify the factors related to CRC in individuals of South Asian ethnicity. Recommending CRC screening by physicians and mid-level providers and educating patients with culturally sensitive programs and materials are important to increase knowledge and awareness of CRC and CRC screening.  相似文献

The performance of combining fecal immunochemical tests (FITs) and a high-risk factor questionnaire (HRFQ) in colorectal cancer (CRC) screening in economically and medically underserved populations is uncertain. This study investigated the performance of a CRC screening protocol of combining FITs and an HRFQ as primary screening methods in a rural Chinese population. A CRC mass screening was conducted using FITs and an HRFQ as the first and colonoscopy as the second stage of screening in Jiashan, 2007-2009. The target population was 31,963 residents in three communities. The compliance was 84.7% for HRFQ, 76.4% for FITs, and 78.7% for colonoscopy. The detected rates of cancer, adenoma, nonadenomatous polyps, and advanced neoplasm were 2.7%, 14.8%, 5.9%, and 8.9% by FITs, which were higher than those by HRFQ (0.5%, 9.2%, 4.8%, and 3.8%, respectively). There was no significant difference in detected rate for nonadenomatous polyps between FITs and HRFQ. A total of 41.2% adenomas, 53.2% nonadenomatous polyps, and 29.8% advanced neoplasms were detected by HRFQ but missed by FITs. Positive predictive value of the screening protocol of combining FITs and HRFQ for advanced neoplasm was 5.7%, which was higher than FITs alone. Men had a higher prevalence of advanced neoplasm than women. Results indicate that combining FITs and HRFQ as primary screening methods is an efficient CRC screening strategy in economically and medically underserved populations.  相似文献

First implemented in 1990, patient navigation interventions are emerging today as an approach to reduce cancer disparities. However, there is lack of consensus about how patient navigation is defined, what patient navigators do, and what their qualifications should be. Little is known about the efficacy and cost-effectiveness of patient navigation. For this review, the authors conducted a qualitative synthesis of published literature on cancer patient navigation. By using the keywords 'navigator' or 'navigation' and 'cancer,' 45 articles were identified in the PubMed database and from reference searches that were published or in press through October 2007. Sixteen studies provided data on the efficacy of navigation in improving timeliness and receipt of cancer screening, diagnostic follow-up care, and treatment. Patient navigation services were defined and differentiated from other outreach services. Overall, there was evidence of some degree of efficacy for patient navigation in increasing participation in cancer screening and adherence to diagnostic follow-up care after the detection of an abnormality. The reported increases in screening ranged from 10.8% to 17.1%, and increases in adherence to diagnostic follow-up care ranged from 21% to 29.2% compared with control patients. There was less evidence regarding the efficacy of patient navigation in reducing either late-stage cancer diagnosis or delays in the initiation of cancer treatment or improving outcomes during cancer survivorship. There were methodological limitations in most studies, such as a lack of control groups, small sample sizes, and contamination with other interventions. Although cancer-related patient navigation interventions are being adopted increasingly across the United States and Canada, further research will be necessary to evaluate their efficacy and cost-effectiveness in improving cancer care.  相似文献

Patient navigators—individuals who assist patients through the healthcare system to improve access to and understanding of their health and healthcare—are increasingly used for underserved individuals at risk for or with cancer. Navigation programs can improve access, but it is unclear whether they improve the efficiency and efficacy of cancer diagnostic and therapeutic services at a reasonable cost, such that they would be considered cost‐effective. In the current study, the authors outline a conceptual model for evaluating the cost‐effectiveness of cancer navigation programs. They describe how this model is being applied to the Patient Navigation Research Program, a multicenter study supported by the National Cancer Institute's Center to Reduce Cancer Health Disparities. The Patient Navigation Research Program is testing navigation interventions that aim to reduce time to delivery of quality cancer care (noncancer resolution or cancer diagnosis and treatment) after identification of a screening abnormality. Examples of challenges to evaluating cost‐effectiveness of navigation programs include the heterogeneity of navigation programs, the sometimes distant relation between navigation programs and outcome of interest (eg, improving access to prompt diagnostic resolution and life‐years gained), and accounting for factors in underserved populations that may influence both access to services and outcomes. In this article, the authors discuss several strategies for addressing these barriers. Evaluating the costs and impact of navigation will require some novel methods, but will be critical in recommendations concerning dissemination of navigation programs.

Washington, DC, has one of the highest incidence and mortality rates for breast cancer in the USA. Patient navigation coupled with informational and community resources are important strategies that assist patients’ access and help them understand the complex world of cancer care. The Georgetown Lombardi Comprehensive Cancer Center’s Capital Breast Care Center (CBCC) is a safety net mammography screening center that utilizes a community-based navigation program. In addition to providing assistance with coordination of clinical services, navigators at CBCC are integral in establishing intra-community partnerships to educate members of the community about breast cancer screening. The aim of this study was to detail the role of patient navigation at the CBCC, with an emphasis on community engagement and community-based partnerships. We describe the process by which CBCC established partnerships with multiple community organizations between 2004 and 2015 and analyzed data of women screened in relationship to the evolution of the patient navigation services. Application of the CBCC navigation model that integrates individual patient outreach with community engagement has yielded viable and lasting community partnerships that have resulted in an increase in mammography uptake, especially among medically underserved minority women.  相似文献

Objective: The aim of this systematic review and meta-analysis was to determine the efficacy of different mHealth interventions in increasing colorectal cancer (CRC) screening rates. Methods: A literature search for eligible studies was done in ClinicalTrials.gov, PubMed, and Scopus in October 2020. Included studies were randomized controlled trials done on adults due for CRC screening, who received either an mHealth intervention to promote screening or usual care. The primary outcome from these studies was completion of CRC screening. Two reviewers independently worked on selecting studies, collecting data, and determining risk of bias. Adjusted odds ratios (AOR) for CRC screening rates were summarized into a Forest plot. Results: A total of ten trials from three continents were included in the qualitative analysis. Risk of bias is low in terms of randomization, but high in terms of participant blinding, due to the nature of the interventions. Meta-analysis of four trials showed low clinical and statistical heterogeneity (I2=0%). Overall, the use of mHealth interventions is associated with higher CRC screening uptake when compared to usual care (AOR 1.33; 95% CI, 1.20-1.46). This effect was seen across different types of mHealth interventions, which included automated and non-automated telephone education and text-message reminders. Conclusion: This study showed that mHealth is associated with increased CRC screening participation regardless of the type of intervention used.  相似文献

BACKGROUND: The purpose of the current study was to provide health professionals, professional organizations, policy makers, and the general public with a practical blueprint for increasing the practice of screening for colorectal carcinoma (CRC) and adenomatous polyps over the next decade. The National Colorectal Cancer Roundtable (NCCRT) was founded in 1997 by the American Cancer Society and the Centers for Disease Control and Prevention to provide strategic leadership, advocacy, long-range planning, and coordination of interventions targeted at reducing the disease burden of CRC through education, early detection, and prevention. The NCCRT and its three workgroups include CRC survivors; recognized experts in primary care, gastroenterology, radiology, colorectal surgery, nursing, public policy, epidemiology, and behavioral science; patient advocates; and representatives of health plans and insurers, government, and other organizations. METHODS: The NCCRT performed a literature review of published and unpublished data related to CRC screening guidelines, compliance, and barriers to adherence, as well as test effectiveness and cost-effectiveness. Members of the three NCCRT workgroups developed summary reports regarding professional education, public education and awareness, and health policy. A drafting committee developed the final strategic plan from workgroup reports, which was reviewed by the entire NCCRT membership, amended, and subsequently approved in final form. RESULTS AND CONCLUSIONS: Although the rationale for population-wide CRC screening is well established, the majority of adults in the U.S. are not currently being screened for CRC. Thus, the nation foregoes an opportunity to reduce CRC-related mortality by an estimated >or= 50%. To increase CRC screening rates, the issues of patient and physician barriers to screening, lack of universal coverage, lack of incentives to motivate adherence, and expanded infrastructure must be addressed.  相似文献

Nine databases were searched for studies reporting a range of measures on the effectiveness of screening for oral cancer and precancer in primary care. Of 1114 papers generated in a search of nine databases, full texts of 90 were scrutinised by two reviewers to ensure that they were concerned with oral cancer/precancer, reported an oral cancer screening programme/exercise and included at least one effectiveness outcome. Criteria for considering studies for the review covered types of studies, participants, interventions and outcome measures. The latter included measures of both end point and interim outcome and also process. Of 90 full text articles screened, examiners agreed on the inclusion of 28 (initial agreement -- kappa=0.60). The remaining 62 were excluded and the reasons recorded. The studies included showed substantial heterogeneity regarding objectives and study design, location and setting, numbers and characteristics of participants, screening personnel, methods of recruitment and types of data collected. Only one study, from the Indian sub-continent, reported a randomised controlled trial: interim results showed 14.9% of intervention subjects died after 3 years compared with 56.3% of non-intervention controls. The review overall produced no evidence in favour of or against the potential benefits associated with an oral cancer screening programme. It was concluded that there are insufficient available data to make an unequivocal determination as to the effectiveness of oral cancer screening programmes at the present time. However, a recent further report on the Indian study published after completion of the review, provides some evidence that screening for oral cancer may be effective, at least in developing countries with a high incidence of the disease.  相似文献

IntroductionMultiple screening methods for malnutrition are available, but a systematic review of evidence in patients with colorectal cancer (CRC) is lacking. The aim of this study is to systematically investigate which outcome variables of nutritional screening methods are associated with treatment tolerance in patients with CRC.Material and MethodsA systematic review was performed with respect to outcome variables of nutritional screening methods and their association with systemic treatment tolerance in patients with CRC. The Cochrane guidelines for systematic reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Two authors independently assessed the risk of bias and quality of each included study.ResultsA total of sixteen studies were included. The following screening methods for malnutrition were assessed in the included studies: serum albumin, body mass index, C-reactive protein/albumin ratio, modified version of the Glasgow prognostic score, mini nutritional assessment, nutritional risk index, patient-generated subjective global assessment, sarcopenia and weight loss.DiscussionSarcopenia tended to be associated with treatment tolerance more often than other screening methods but the current review suggests that there are ample screening methods rendering meaningful outcomes regarding a patient's nutritional status and associated risk for treatment intolerance. This grants practitioners the flexibility to choose from a variety of different nutritional screening methods. Nutritional screening can thus be tailored to the individual patient. Importantly, nutritional screening may help identify those patients at risk for chemotoxicity thus allowing for the implementation of targeted prehabilitation programs in order to prevent (severe) chemotoxicity.  相似文献

Population screening for colorectal cancer (CRC) has recently commenced in the United Kingdom supported by the evidence of a number of randomised trials and pilot studies. Certain factors are known to influence screening cost-effectiveness (e.g. compliance), but it remains unclear whether an ageing population (i.e. demographic change) might also have an effect. The aim of this study was to simulate a population-based screening setting using a Markov model and assess the effect of increasing life expectancy on CRC screening cost-effectiveness. A Markov model was constructed that aimed, using a cohort simulation, to estimate the cost-effectiveness of CRC screening in an England and Wales population for two timescales: 2003 (early cohort) and 2033 (late cohort). Four model outcomes were calculated; screened and non-screened cohorts in 2003 and 2033. The screened cohort of men and women aged 60 years were offered biennial unhydrated faecal occult blood testing until the age of 69 years. Life expectancy was assumed to increase by 2.5 years per decade. There were 407 552 fewer people entering the model in the 2033 model due to a lower birth cohort, and population screening saw 30 345 fewer CRC-related deaths over the 50 years of the model. Screening the 2033 cohort cost £96 million with cost savings of £43 million in terms of detection and treatment and £28 million in palliative care costs. After 30 years of follow-up, the cost per life year saved was £1544. An identical screening programme in an early cohort (2003) saw a cost per life year saved of £1651. Population screening for CRC is costly but enables cost savings in certain areas and a considerable reduction in mortality from CRC. This Markov simulation suggests that the cost-effectiveness of population screening for CRC in the United Kingdom may actually be improved by rising life expectancies.  相似文献

Asian Americans are among the fastest growing population groups in the USA. Despite the fact that colorectal cancer (CRC) is the second most common cancer for this group, Asian Americans have low CRC screening rates. An established health promotion program, Healthy Asian Americans Project (HAAP), expanded to include community-based CRC education during 2005–2006. Using Asian-language media, HAAP promoted awareness throughout local Asian Indian, Chinese, Filipino, Hmong, Japanese, Korean, and Vietnamese American communities and recruited men and women over 50 years to attend health fairs at local community/cultural centers. Evaluation data from 304 participants in an evidence-based educational intervention showed significantly increased knowledge and attitudes about the importance of screening. Follow-up conducted between 6 and 12 months showed that 78% of those receiving the educational intervention had been screened in the last 12 months, compared with the 37% who had ever been screened with any of the tests prior to the study. This community-based health promotion program reached underserved populations and the educational intervention improved CRC screening rates. This and similar programs may help lower CRC mortality among Asian Americans.  相似文献

National colonoscopy adherence rates near 65 % and New York City (NYC) colonoscopy rates approach 69 %. Despite an overall increase in national colorectal cancer (CRC) screening rates, rates of CRC screening among Blacks and Latinos are lower than non-Latino Whites. We developed two group level, culturally targeted educational programs about CRC for Blacks and Latinos. One hour programs included education about screening, peer testimony given by a colonoscopy-adherent person, and pre- and post-knowledge assessment. From 2010 to 2012, we conducted 66 education programs in NYC, reaching 1,065 participants, 62.7 % of whom were 50 years of age or older identified as Black or Latino and provided information about colonoscopy history (N?=?668). Colonoscopy adherence in the sample was 69.3 %. There was a significant increase in mean knowledge score about CRC and CRC screening from pretest to posttest. Sixty-eight percent of attendees without prior colonoscopy reported intent to schedule a colonoscopy as a result of attending the program. Culturally targeted education programs with peer testimony are a valuable way to raise awareness about CRC and colonoscopy and can influence intent to screen among nonadherent persons. Additional research is needed to establish group level education as an effective means of promoting CRC screening.  相似文献

Background: Today, only carcinoma of the bronchus kills more people thancolorectal cancer (CRC). However, CRC is both preventable and curable. InNorway, projects aiming to detect adenomas and early cancers by thescreening of a population aged about 60 years employing sigmoidoscopy havebeen discussed.Materials and methods: In this study, a mathematical model was used toestimate the cost-effectiveness of a screening programme for colorectalpolyps followed by polypectomy. A once-only sigmoidoscopy at age 60 followedby coloscopy in selected risk groups was suggested. Data from theEnglish-language literature, the National Cancer Registry of Norway, andStatistics Norway were included. Norwegian cost data from the NationalHealth Administration were also used. Costs of screening and those relatedto earlier diagnosis, and savings on health care and averted loss inproduction due to prevented CRCs were calculated.Results: The basic cost per patient invited and screened (70%compliance) in the suggested programme was estimated at £81.7 and£116.7, respectively. When gains due to prevented CRCs were included,the figures became £34.5 and £49.2. The cost per life-year savedwas calculated as £2,889. This strongly indicates that screening forthe early detection and prevention of CRC is one of the most cost-effectiveprogrammes in cancer.Conclusions: CRC screening according to the suggested programme appears tobe cost-effective. Clear evidence that screening can reduce mortality from CRCshould convince health-care policy makers that the time has come to encouragescreening for colorectal cancer.  相似文献

Summary In 1986, the National Cancer Institute published its cancer control objectives for the nation, which included projected reductions in breast cancer mortality. The reductions were estimated to be 25.0% from reducing fat, 16.0% from expanding use of breast cancer screening services, and 14.3% from expanding access to state-of-the-art breast cancer treatment. During the same decade, the U.S. population aged and became significantly more ethnically diverse, and accompanying this increase in ethnic diversity was endemic poverty, disproportionately experienced by black and Hispanic minorities. These populations may be seen as medically underserved. With respect to breast cancer, as well as many other cancers, the medically underserved are understudied, not well understood by many in the medical and academic research community, and attended by health care institutions that are under-funded and often do not have the resources necessary to ensure access to state-of-the-art cancer screening, clinical follow-up, diagnosis, and treatment. At the same time, medically underserved women are more likely to be diagnosed with late-stage breast cancer, and some groups (e.g. black women) bear the greatest breast cancer mortality burden in the nation. In this special issue of Breast Cancer Research and Treatment, eight papers describe what we know and what we don't about breast cancer prevention and control in medically underserved populations.  相似文献

Many cancer-prevention interventions have demonstrated effectiveness in diverse populations, but these evidenced-based findings slowly disseminate into practice. The current study describes the process of disseminating and replicating research (i.e., peer patient navigation for colonoscopy screening) in real-world settings. Two large metropolitan hospitals collaborated to replicate a peer patient navigation model within their existing navigation systems. Six African-American peer volunteers were recruited and trained to navigate patients through colonoscopy scheduling and completion. Major challenges included: (1) operating within multiple institutional settings; (2) operating within nonacademic/research infrastructures; (3) integrating into an established navigation system; (4) obtaining support of hospital staff without overburdening; and (5) competing priorities and time commitments. Bridging the gap between evidence-based research and practice is critical to eliminating many cancer health disparities; therefore, it is crucial that researchers and practitioners continue to work to achieve both diffusion and fusion of evidence-based findings. Recommendations for addressing these challenges are discussed.  相似文献
