Improving follow-up to abnormal breast cancer screening in an urban population

A qualitative assessment of community-based breast health navigation services for Southeast Asian women in Southern California: recommendations for developing a navigator training curriculum

OBJECTIVES

We identified key elements required for a training curriculum for Southeast Asian community-based health navigators (CBHNs), who help low-income, immigrant Cambodian, Laotian, Thai, and Vietnamese women negotiate cultural and systemic barriers to breast cancer screening and care in the United States.

METHODS

We gathered the perspectives of 3 groups: CBHNs, community members, and their providers. We conducted 16 focus groups with 110 women representing different stages of the cancer care continuum and in-depth interviews with 15 providers and 10 navigators to identify the essential roles, skills, and interpersonal qualities that characterize successful CBHNs.

RESULTS

The most important areas identified for training CBHNs were information (e.g., knowing pertinent medical information and how to navigate resources), logistics (transportation, interpretation), and affective interpersonal skills (understanding the language and cultural beliefs of patients, communicating with providers, establishing trust).

CONCLUSIONS

CBHNs serve a crucial role in building trust and making screening practices culturally meaningful, accessible, usable, and acceptable. Future research should focus on developing training curricula, policies, resources, and funding to better maximize the expertise and services that CBHNs provide and to expand our findings to other underserved communities.

Nurses as patient navigators in cancer diagnosis: review, consultation and model design

The diagnostic phase of cancer care is an anxious time for patients. Patient navigation is a way of assisting and supporting individuals during this time. The aim of this review is to explore patient navigation and its role in the diagnostic phase of cancer care. We reviewed the literature for definitions and models of navigation, preparation for the role and impact on patient outcomes, specifically addressing the role of the nurse in patient navigation. Interviews and focus groups with healthcare providers and managers provided further insight from these stakeholder groups. Common to most definitions of navigation is the navigator's multifaceted role in facilitating processes of care, assisting patients to overcome barriers and providing information and support. Navigation may be provided by laypersons, clerical staff and/or healthcare professionals. In the diagnostic phase it has the potential to affect efficiency of diagnostic testing, patients' experience during this time and preparation for decision-making around treatment options. Patient care during the diagnostic phase requires various levels of navigation, according to individual informational, physical and psychosocial needs. Identifying those individuals who require more support--whether physical or psychosocial--during the diagnostic phase is of critical importance.

Are breast cancer navigation programs cost-effective? Evidence from the Chicago Cancer Navigation Project

OBJECTIVES

One of the aims of the Chicago Cancer Navigation Project (CCNP) is to reduce the interval of time between abnormal breast cancer screening and definitive diagnosis in patients who are navigated as compared to usual care. In this article, we investigate the extent to which total costs of breast cancer navigation can be offset by survival benefits and savings in lifetime breast cancer-attributable costs.

METHODS

Data sources for the cost-effectiveness analysis include data from published literature, secondary data from the NCI's Surveillance Epidemiology and End Results (SEER) program, and primary data from the CCNP.

RESULTS

If women enrolled in CCNP receive breast cancer diagnosis earlier by 6 months as compared to usual care, then navigation is borderline cost-effective for $95,625 per life-year saved. Results from sensitivity analyses suggest that the cost-effectiveness of navigation is sensitive to: the interval of time between screening and diagnosis, percent increase in number of women who receive cancer diagnosis and treatment, women's age, and the positive predictive value of a mammogram.

CONCLUSIONS

In planning cost-effective navigation programs, special considerations should be made regarding the characteristics of the disease, program participants, and the initial screening test that determines program eligibility.

Peer navigation improves diagnostic follow-up after breast cancer screening among Korean American women: results of a randomized trial

Objective

To test an intervention to increase adherence to diagnostic follow-up tests among Asian American women.

Methods

Korean American women who were referred for a diagnostic follow-up test (mainly diagnostic mammograms) and who had missed their follow-up appointment were eligible to participate in the study. Women from two clinics (n = 176) were randomly allocated to a usual care control arm or a peer navigator intervention arm. A 20-min telephone survey was administered to women in both study arms six months after they were identified to assess demographic and socio-economic characteristics and the primary outcome, self-reported completion of the recommended follow-up exam.

Results

Among women who completed the survey at six-month follow-up, self-reported completion of follow-up procedures was 97% in the intervention arm and 67% in the control arm (p < 0.001). Based on an intent-to-treat analysis of all women who were randomized and an assumption of no completion of follow-up exam for women with missing outcome data, self-reported completion of follow-up was 61% in the intervention arm and 46% in the usual care control arm (p < 0.069).

Conclusions

Our results suggest that a peer navigator intervention to assist Korean American women to obtain follow-up diagnostic tests after an abnormal breast cancer screening test is efficacious.

Characteristics and predictors of missed opportunities in lung cancer diagnosis: an electronic health record-based study

PURPOSE

Understanding delays in cancer diagnosis requires detailed information about timely recognition and follow-up of signs and symptoms. This information has been difficult to ascertain from paper-based records. We used an integrated electronic health record (EHR) to identify characteristics and predictors of missed opportunities for earlier diagnosis of lung cancer.

METHODS

Using a retrospective cohort design, we evaluated 587 patients of primary lung cancer at two tertiary care facilities. Two physicians independently reviewed each case, and disagreements were resolved by consensus. Type I missed opportunities were defined as failure to recognize predefined clinical clues (ie, no documented follow-up) within 7 days. Type II missed opportunities were defined as failure to complete a requested follow-up action within 30 days.

RESULTS

Reviewers identified missed opportunities in 222 (37.8%) of 587 patients. Median time to diagnosis in cases with and without missed opportunities was 132 days and 19 days, respectively (P < .001). Abnormal chest x-ray was the clue most frequently associated with type I missed opportunities (62%). Follow-up on abnormal chest x-ray (odds ratio [OR], 2.07; 95% CI, 1.04 to 4.13) and completion of first needle biopsy (OR, 3.02; 95% CI, 1.76 to 5.18) were associated with type II missed opportunities. Patient adherence contributed to 44% of patients with missed opportunities.

CONCLUSION

Preventable delays in lung cancer diagnosis arose mostly from failure to recognize documented abnormal imaging results and failure to complete key diagnostic procedures in a timely manner. Potential solutions include EHR-based strategies to improve recognition of abnormal imaging and track patients with suspected cancers.

Tracking abnormal cervical cancer screening: evaluation of an EMR-based intervention

INTRODUCTION

System level barriers have been associated with inadequate follow-up of abnormal cervical cytology.

OBJECTIVE

The aim of this study was to develop and evaluate an electronic tracking system to improve follow-up of abnormal Pap tests.

PROGRAM DESCRIPTION

We implemented an electronic medical record (EMR)-based Pap test tracking system at two clinical practices at an inner-city academic health center. The system generated a provider-specific monthly report of all abnormal Pap results, and provided a patient-specific Pap tracking table embedded in the EMR for each subject.

EVALUATION

We compared abnormal Pap test follow-up rates for the 24 months pre-intervention with rates 12 months following its implementation (post-intervention). The evaluation followed all subjects for 12 months from the date of their abnormal Pap test, looking for diagnostic resolution.

RESULTS

Subjects were young women (mean age = 30.5) of primarily white (42%) and African American (37%) descent, who spoke English (88%). Forty-eight percent were insured through publicly subsidized insurance. Controlling for type of abnormality and practice location, the adjusted mean time to resolution decreased significantly from 108 days (confidence interval, CI 105-112 days) in the pre-intervention period to 86 days (CI 81-91 days).

CONCLUSION

Our study cannot demonstrate that with follow up, we directly avoided cases of invasive cervical cancer. However, we show that in an at-risk urban population, an automated, EMR-based tracking system reduced the time to resolution, and increased the number of women who achieved diagnostic resolution.

Psychosocial determinants of mammography follow-up after receipt of abnormal mammography results in medically underserved women

This article targets the relationship between psychosocial determinants and abnormal screening mammography follow-up in a medically underserved population. Health belief scales were modified to refer to diagnostic follow-up versus annual screening. A retrospective cohort study design was used. Statistical analyses were performed examining relationships among sociodemographic factors, psychosocial determinants, and abnormal mammography follow-up. Women with lower mean internal health locus of control scores (3.14) were two times more likely than women with higher mean internal health locus of control scores (3.98) to have inadequate follow-up (OR=2.53, 95% CI=1.12-5.36). Women with less than a high school education had lower cancer fatalism scores than women who had completed high school (47.5 vs. 55.2, p-value=.02) and lower mean external health locus of control scores (3.0 vs. 5.3) (p-value<.01). These constructs have implications for understanding mammography follow-up among minority and medically underserved women. Further comprehensive study of these concepts is warranted.

Cancer care at the hospital-community interface: perspectives of patients from different cultural and ethnic groups

OBJECTIVE

To examine perceptions of cancer patients from different cultural and ethnic groups regarding the quality of their care at the hospital-community interface.

METHODS

Cross-sectional study of cancer patients from a large tertiary center in Israel. Patients were surveyed on the quality of their primary-care and on their transition from the hospital. Regression analyses were used to examine differences among Hebrew-, Russian-, and Arabic-speaking patients in their assessment of six primary-care domains and of their care transition process.

RESULTS

422 patients completed the survey. Russian speakers gave the lowest and Arabic speakers the highest ratings for all primary care domains. Arabic speakers also gave higher ratings for their care transition process than the other two groups. Minority patients' primary-care physicians were significantly more likely than Hebrew speakers' physicians to facilitate the hospital transition process by reviewing the discharge recommendations.

CONCLUSIONS

Cancer patients from different ethnic groups differ in their primary-care experience and their perceptions of their hospital to community transition. Primary-care physicians serve as facilitators of care transitions by discussing discharge recommendations with their minority patients.

PRACTICE IMPLICATIONS

Reviewing the discharge recommendations with the patient at the post-discharge primary-care visit is an important contributor to high quality transitional care.

Timely care after an abnormal mammogram among low-income women in a public breast cancer screening program

BACKGROUND

Since 1990, the National Breast and Cervical Cancer Early Detection Program (BCCEDP) has funded breast cancer screening and diagnostic services for low-income, underinsured women. Case management was implemented in 2001 to address barriers to follow-up after an abnormal mammogram, and free treatment was introduced in 2004. However, the effect of these policies on timeliness of care has not been empirically evaluated.

METHODS

Among 2252 BCCEDP participants in Massachusetts during 1998 through 2007, we conducted a time-to-event analysis with prepolicy-postpolicy comparisons to examine associations of case management and free treatment with diagnostic and treatment delays (>60 days and >90 days, respectively) after an abnormal mammogram.

RESULTS

The proportion of women experiencing a diagnostic delay decreased from 33% to 23% after the introduction of case management (P < .001), with a significant reduction in the adjusted risk of diagnostic delay (relative risk [RR], 0.65; 95% confidence interval [CI], 0.53-0.79) that did not differ by race and ethnicity. However, case management was not associated with changes in treatment delay (RR, 0.93; 95% CI, 0.80-1.10). Free treatment was not associated with changes in the adjusted risk of diagnostic delay (RR, 0.61; 95% CI, 0.33-1.14) or treatment delay (RR, 0.77; 95% CI, 0.43-1.38) beyond improvements associated with case management.

CONCLUSIONS

Case management to assist women in overcoming logistic and psychosocial barriers to care may improve time to diagnosis among low-income women who receive free breast cancer screening and diagnostic services. Programs that provide services to coordinate care, in addition to free screening and diagnostic tests, may improve population health.

Pilots of oncology health care: a concept analysis of the patient navigator role

PURPOSE/OBJECTIVES

To summarize the current scientific literature pertaining to the role of the patient navigator in oncology using the concept analysis framework developed by Walker and Avant.

DATA SOURCES

Published research articles, clinical articles, and Internet sources on patient navigator roles and programs. Literature was obtained from CINAHL, PubMed, PsycINFO, the Cochrane Library, and Google Scholar, incorporating reports in English from 1990-2008.

DATA SYNTHESIS

Patient navigation has received a plethora of attention as healthcare programs strive to streamline care and address current gaps in service delivery. The literature revealed that the role of the patient navigator remains context-specific and has been filled by a variety of individuals, including nurses, social workers, peer supporters, and lay individuals.

CONCLUSIONS

The role of a patient navigator includes removing barriers to care, improving patient outcomes, and ameliorating the overall quality of healthcare delivery.

IMPLICATIONS FOR NURSING

By examining the role of the patient navigator depicted in the scientific literature, nurses can gain insight into not only the features of navigation but also the current systematic gaps that call for navigation services. This article examines the numerous functions of a patient navigator and exemplifies the significance of the role in various domains.

Patient navigation: development of a protocol for describing what navigators do

OBJECTIVE

To develop a structured protocol for observing patient navigators at work, describing and characterizing specific activities related to their goals.

DATA SOURCES/SETTING

Fourteen extended observations of navigators at three programs within a national trial of patient navigation.

STUDY DESIGN

Preliminary observations were guided by a conceptual model derived from the literature and expert consensus, then coded to develop and refine observation categories. These findings were then used to develop the protocol.

METHODS

Observation fieldnotes were coded, using both a priori codes and new codes based on emergent themes. Using these codes, the team refined the model and constructed an observation tool that enables consistent categorization of the observed range of navigator actions.

FINDINGS

Navigator actions across a wide variety of settings can be categorized in a matrix with two dimensions. One dimension categorizes the individuals and organizational entities with whom the navigator interacts; the other characterizes the types of tasks carried out by the navigators in support of their patients.

CONCLUSIONS

Use of this protocol will enable researchers to systematically characterize and compare navigator activities within and across programs.

Evaluating the cost-effectiveness of cancer patient navigation programs: conceptual and practical issues

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.

Timely follow-up of abnormal diagnostic imaging test results in an outpatient setting: are electronic medical records achieving their potential?

BACKGROUND

Given the fragmentation of outpatient care, timely follow-up of abnormal diagnostic imaging results remains a challenge. We hypothesized that an electronic medical record (EMR) that facilitates the transmission and availability of critical imaging results through either automated notification (alerting) or direct access to the primary report would eliminate this problem.

METHODS

We studied critical imaging alert notifications in the outpatient setting of a tertiary care Department of Veterans Affairs facility from November 2007 to June 2008. Tracking software determined whether the alert was acknowledged (ie, health care practitioner/provider [HCP] opened the message for viewing) within 2 weeks of transmission; acknowledged alerts were considered read. We reviewed medical records and contacted HCPs to determine timely follow-up actions (eg, ordering a follow-up test or consultation) within 4 weeks of transmission. Multivariable logistic regression models accounting for clustering effect by HCPs analyzed predictors for 2 outcomes: lack of acknowledgment and lack of timely follow-up.

RESULTS

Of 123 638 studies (including radiographs, computed tomographic scans, ultrasonograms, magnetic resonance images, and mammograms), 1196 images (0.97%) generated alerts; 217 (18.1%) of these were unacknowledged. Alerts had a higher risk of being unacknowledged when the ordering HCPs were trainees (odds ratio [OR], 5.58; 95% confidence interval [CI], 2.86-10.89) and when dual-alert (>1 HCP alerted) as opposed to single-alert communication was used (OR, 2.02; 95% CI, 1.22-3.36). Timely follow-up was lacking in 92 (7.7% of all alerts) and was similar for acknowledged and unacknowledged alerts (7.3% vs 9.7%; P = .22). Risk for lack of timely follow-up was higher with dual-alert communication (OR, 1.99; 95% CI, 1.06-3.48) but lower when additional verbal communication was used by the radiologist (OR, 0.12; 95% CI, 0.04-0.38). Nearly all abnormal results lacking timely follow-up at 4 weeks were eventually found to have measurable clinical impact in terms of further diagnostic testing or treatment.

CONCLUSIONS

Critical imaging results may not receive timely follow-up actions even when HCPs receive and read results in an advanced, integrated electronic medical record system. A multidisciplinary approach is needed to improve patient safety in this area.

Underuse of breast cancer adjuvant treatment: patient knowledge, beliefs, and medical mistrust

PURPOSE

Little is known about why women with breast cancer who have surgery do not receive proven effective postsurgical adjuvant treatments.

METHODS

We surveyed 258 women who recently underwent surgical treatment at six New York City hospitals for early-stage breast cancer about their care, knowledge, and beliefs about breast cancer and its treatment. As per national guidelines, all women should have received adjuvant treatment. Adjuvant treatment data were obtained from inpatient and outpatient charts. Factor analysis was used to create scales scored to 100 of treatment beliefs and knowledge, medical mistrust, and physician communication about treatment. Bivariate and multivariate analyses assessed differences between treated and untreated women.

RESULTS

Compared with treated women, untreated women were less likely to know that adjuvant therapies increase survival (on a 100-point scale; 66 v 75; P < .0001), had greater mistrust (64 v 53; P = .001), and had less self-efficacy (92 v 97; P < .05); physician communication about treatment did not affect patient knowledge of treatment benefits (r = 0.8; P = .21). Multivariate analysis found that untreated women were more likely to be 70 years or older (adjusted relative risk [aRR], 1.11; 95% CI, 1.00 to 1.13), to have comorbidities (aRR, 1.10; 95% CI, 1.04 to 1.12), and to express mistrust in the medical delivery system (aRR, 1.003; 95% CI, 1.00 to 1.007), even though they were more likely to believe adjuvant treatments were beneficial (aRR, 0.99; 95% CI, 0.98 to 0.99; model c, 0.84; P < or = .0001).

CONCLUSION

Patient knowledge and beliefs about treatment and medical mistrust are mutable factors associated with underuse of effective adjuvant therapies. Physicians may improve cancer care by ensuring that discussions about adjuvant therapy include a clear presentation of the benefits, not just the risks of treatment, and by addressing patient trust in and concerns about the medical system.

A multilevel intervention to promote colorectal cancer screening among community health center patients: results of a pilot study

BACKGROUND

Colorectal cancer screening rates are low among poor and disadvantaged patients. Patient navigation has been shown to increase breast and cervical cancer screening rates, but few studies have looked at the potential of patient navigation to increase colorectal cancer screening rates.

METHODS

The objective was to determine the feasibility and effectiveness of a patient navigator-based intervention to increase colorectal cancer screening rates in community health centers. Patients at the intervention health center who had not been screened for colorectal cancer and were designated as "appropriate for outreach" by their primary care providers received a letter from their provider about the need to be screened and a brochure about colorectal cancer screening. Patient navigators then called patients to discuss screening and to assist patients in obtaining screening. Patients at a demographically similar control health center received usual care.

RESULTS

Thirty-one percent of intervention patients were screened at six months, versus nine percent of control patients (p < .001).

CONCLUSION

A patient navigator-based intervention, in combination with a letter from the patient's primary care provider, was associated with an increased rate of colorectal cancer screening at one health center as compared to a demographically similar control health center. Our study adds to an emerging literature supporting the use of patient navigators to increase colorectal cancer screening in diverse populations served by urban health centers.

Addressing social determinants of health to improve access to early breast cancer detection: results of the Boston REACH 2010 Breast and Cervical Cancer Coalition Women's Health Demonstration Project

BACKGROUND

The Boston Racial and Ethnic Approaches to Community Health (REACH) 2010 Breast and Cervical Cancer Coalition developed a case management intervention for women of African descent to identify and reduce medical and social obstacles to breast cancer screening and following up abnormal results.

METHODS

We targeted black women at high risk for inadequate cancer screening and follow-up as evidenced by a prior pattern of missed clinic appointments and frequent urgent care use. Case managers provided referrals to address patient-identified social concerns (e.g., transportation, housing, language barriers), as well as navigation to prompt screening and follow-up of abnormal tests. We recruited 437 black women aged 40-75, who received care at participating primary care sites. The study was conducted as a prospective cohort study rather than as a controlled trial and evaluated intervention effects on mammography uptake and longitudinal screening rates via logistic regression and timely follow-up of abnormal tests via Cox proportional hazards models.

RESULTS

A significant increase in screening uptake was found (OR 1.53, 95% CI 1.13-2.08). Housing concerns (p < 0.05) and lacking a regular provider (p < 0.01) predicted poor mammography uptake. Years of participation in the intervention increased odds of obtaining recommended screening by 20% (OR 1.20, 95% CI 1.02-1.40), but this effect was attenuated by covariates (p = 0.53). Timely follow-up for abnormal results was achieved by most women (85%) but could not be attributed to the intervention (HR 0.95, 95% CI 0.50-1.80).

CONCLUSIONS

Case management was successful at promoting mammography screening uptake, although no change in longitudinal patterns was found. Housing concerns and lacking a regular provider should be addressed to promote mammography uptake. Future research should provide social assessment and address social obstacles in a randomized controlled setting to confirm the efficacy of social determinant approaches to improve mammography use.

An evaluation of the cost-effectiveness of policy navigators to improve access to care for the poor in the Philippines

OBJECTIVES

Even when health insurance coverage is available, health policies may not be effective at increasing coverage among vulnerable populations. New approaches are needed to improve access to care. We experimentally introduced a novel intervention that uses Policy Navigators to increase health insurance enrollment in a poor population.

METHODS

We used data from the Quality Improvement Demonstration Study (QIDS), a randomized experiment taking place at the district level in the Visayas region of the Philippines. In two arms of the study, we compared the effects of introducing Policy Navigators to controls. The Policy Navigators advocated for improved access to care by providing regular system-level expertise directly to the policy-makers, municipal mayors and governors responsible for paying for and enrolling poor households into the health insurance program. Using regression models, we compared levels of enrollment in our intervention versus control sites. We also assessed the cost-effectiveness of marginal increases in enrollment.

RESULTS

We found that Policy Navigators improved enrollment in health insurance between 39% and 102% compared to the controls. Policy navigators were cost-effective at 0.86 USD per enrollee. However, supplementary national government campaigns, which were implemented to further increase coverage, attenuated normal enrollment efforts.

CONCLUSION

Policy Navigators appear to be effective in improving access to care and their success underscores the importance of local-level strategies for improving enrollment.

Using a multifaceted approach to improve the follow-up of positive fecal occult blood test results

OBJECTIVES

Inadequate follow-up of abnormal fecal occult blood test (FOBT) results occurs in several types of practice settings. Our institution implemented multifaceted quality improvement (QI) activities in 2004-2005 to improve follow-up of FOBT-positive results. Activities addressed precolonoscopy referral processes and system-level factors such as electronic communication, provider education, and feedback. We evaluated their effects on timeliness and appropriateness of positive-FOBT follow-up and identified factors that affect colonoscopy performance.

METHODS

Retrospective electronic medical record review was used to determine outcomes before and after QI activities in a multispecialty ambulatory clinic of a tertiary care Veterans Affairs facility and its affiliated satellite clinics. From 1869 FOBT-positive cases, 800 were randomly selected from time periods before and after QI activities. Two reviewers used a pretested standardized data collection form to determine whether colonoscopy was appropriate or indicated based on predetermined criteria and if so, the timeliness of colonoscopy referral and performance before and after QI activities.

RESULTS

In cases where a colonoscopy was indicated, the proportion of patients who received a timely colonoscopy referral and performance were significantly higher post-implementation (60.5% vs. 31.7%, P<0.0001 and 11.4% vs. 3.4%, P=0.0005). A significant decrease also resulted in median times to referral and performance (6 vs. 19 days, P<0.0001 and 96.5 vs. 190 days, P<0.0001) and in the proportion of positive-FOBT test results that had received no follow-up by the time of chart review (24.3% vs. 35.9%, P=0.0045). Significant predictors of absence of the performance of an indicated colonoscopy included performance of a non-colonoscopy procedure such as barium enema or flexible sigmoidoscopy (OR=16.9; 95% CI, 1.9-145.1), patient non-adherence (OR=33.9; 95% CI, 17.3-66.6), not providing an appropriate provisional diagnosis on the consultation (OR=17.9; 95% CI, 11.3-28.1), and gastroenterology service not rescheduling colonoscopies after an initial cancellation (OR=11.0; 95% CI, 5.1-23.7).

CONCLUSIONS

Multifaceted QI activities improved rates of timely colonoscopy referral and performance in an electronic medical record system. However, colonoscopy was not indicated in over one third of patients with positive FOBTs, raising concerns about current screening practices and the appropriate denominator used for performance measurement standards related to colon cancer screening.

Comprehensive diagnostic program for medically underserved women with abnormal breast screening evaluations in an urban population

OBJECTIVE

To institute a patient navigator program for underinsured women to eliminate delays in diagnostic resolution of abnormal screening mammograms, provide services for abnormalities noted during breast cancer screening, describe demographic and clinical characteristics of enrollees, and assess postscreening follow-up care.

PATIENTS AND METHODS

Coordinators from area health departments worked with a navigator nurse at Mayo Clinic Cancer Center in Jacksonville, FL, to refer patients for additional diagnostic services, including diagnostic mammography, ultrasonography, ultrasonography-guided biopsy, stereotactic biopsy, breast magnetic resonance imaging, and biopsy guided by magnetic resonance imaging. Women with abnormal screening mammograms (Breast Imaging Reporting and Data System [BI-RADS] category 4 or 5) or palpable suspect breast masses were eligible. Data were extracted from clinical service records. Timeliness of postscreening follow-up was assessed.

RESULTS

The study enrolled 447 women from June 30, 2000, to December 29, 2006. Data on the time from screening to diagnosis were available for 399 women, and median time from detection of screening abnormality to diagnosis was 37 days. Time between screening and diagnosis was 60 days or less for 325 (81%) of the 399 women for whom data were available and for 60 (82%) of the 73 women with BI-RADS category 4 or 5 assessments. Both of these percentages exceeded the Centers for Disease Control and Prevention quality benchmark of 75%. Mean time from study enrollment to diagnosis was 2 days for women with BI-RADS category 3 or 4 assessments and 7 days for women with BI-RADS category 5 assessments.

CONCLUSION

This program demonstrated a successful collaboration between an academic medical center and community health centers. Most women with BI-RADS category 4 or 5 assessments received a diagnosis within 60 days of screening.

Accuracy of self-reported breast cancer among women undergoing mammography

This study estimated the sensitivity and specificity of self-reported breast cancer and their associations with patient factors and pathologic findings using data from the Breast Cancer Surveillance Consortium. We included 24,631 women with and 463,804 women without a prior diagnosis of breast cancer who completed a questionnaire (including breast cancer history) at participating US mammography facilities between 1996 and 2006. We determined "true" cancer status using cancer registries and pathology databases. Multivariable logistic regression models were used to examine associations with patient factors and pathologic findings. Sensitivity of self-reported breast cancer was higher for women with invasive cancer (96.9%) than for those with ductal carcinoma in situ (DCIS) (90.2%). Specificity was high overall (99.7%) but much lower for women with a history of lobular carcinoma in situ (LCIS) (65.0%). In multivariable models, women reporting older ages, a nonwhite race/ethnicity, or less education had lower sensitivities and specificities. Sensitivity was reduced when there was evidence of prior DCIS, especially when this diagnosis had been made more than 2 years before questionnaire completion. Women reporting a family history of breast cancer had higher sensitivity. Evidence of prior LCIS was associated with lower specificity. The accuracy of self-reported breast cancer depends on the respondent's characteristics and prior diagnoses. Accuracy is lower among nonwhite women and women reporting less education. There appears to be uncertainty surrounding breast findings such as DCIS and LCIS. These results have important implications for research relying on self-report and for patient communication and care.

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

BACKGROUND

Minority racial/ethnic groups have low colorectal cancer (CRC) screening rates.

OBJECTIVE

To evaluate a culturally tailored intervention to increase CRC screening, primarily using colonoscopy, among low income and non-English speaking patients.

DESIGN

Randomized controlled trial conducted from January to October of 2007.

SETTING

Single, urban community health center serving a low-income, ethnically diverse population.

PATIENTS

A total of 1,223 patients 52-79 years of age overdue for CRC screening, randomized to intervention (n = 409) vs. usual care control (n = 814) groups.

INTERVENTION

Intervention patients received an introductory letter with educational material followed by phone or in-person contact by a language-concordant "navigator." Navigators (n = 5) were community health workers trained to identify and address patient-reported barriers to CRC screening. Individually tailored interventions included patient education, procedure scheduling, translation and explanation of bowel preparation, and help with transportation and insurance coverage. Rates of colorectal cancer screening were assessed for intervention and usual care control patients.

RESULTS

Over a 9-month period, intervention patients were more likely to undergo CRC screening than control patients (27% vs. 12% for any CRC screening, p < 0.001; 21% vs. 10% for colonoscopy completion, p < 0.001). The higher screening rate resulted in the identification of 10.5 polyps per 100 patients in the intervention group vs. 6.8 in the control group (p = 0.04).

LIMITATIONS

Patients were from one health center. Some patients may have obtained CRC screening outside our system.

CONCLUSIONS

A culturally tailored, language-concordant navigator program designed to identify and overcome barriers to colorectal cancer screening can significantly improve colonoscopy rates for low income, ethnically and linguistically diverse patients. ClinicalTrials.gov registration number: NCT00476970.

Health care system approaches for cancer patient communication

Cancer patient communication is always embedded in a complex background of inter-related parts, that is, a system. Cancer patients specifically are exposed to a health care system. Considering this context, this article summarizes the insights from a roundtable discussion involving behavioral medicine and oncology experts convened at the 2008 Annual Meeting of the Society of Behavioral Medicine as part of an annual preconference course entitled "Interpersonal Communication and Cancer Control: Emerging Themes." In this article we summarize the communication-relevant components of health care systems, focusing on the macro level. Next, we review existing theoretical frameworks for systems-based communication, the unique aspects of "systems thinking," and the emerging systems tools that can be integrated in cancer communication. Finally, we propose a research agenda for successful system approaches for patient-centered cancer communication.

National Cancer Institute Patient Navigation Research Program: methods, protocol, and measures

BACKGROUND

Patient, provider, and systems barriers contribute to delays in cancer care, a lower quality of care, and poorer outcomes in vulnerable populations, including low-income, underinsured, and racial/ethnic minority populations. Patient navigation is emerging as an intervention to address this problem, but navigation requires a clear definition and a rigorous testing of its effectiveness. Pilot programs have provided some evidence of benefit, but have been limited by evaluation of single-site interventions and varying definitions of navigation. To overcome these limitations, a 9-site National Cancer Institute Patient Navigation Research Program (PNRP) was initiated.

METHODS

The PNRP is charged with designing, implementing, and evaluating a generalizable patient navigation program targeting vulnerable populations. Through a formal committee structure, the PNRP has developed a definition of patient navigation and metrics to assess the process and outcomes of patient navigation in diverse settings, compared with concurrent continuous control groups.

RESULTS

The PNRP defines patient navigation as support and guidance offered to vulnerable persons with abnormal cancer screening or a cancer diagnosis, with the goal of overcoming barriers to timely, quality care. Primary outcomes of the PNRP are 1) time to diagnostic resolution; 2) time to initiation of cancer treatment; 3) patient satisfaction with care; and 4) cost effectiveness, for breast, cervical, colon/rectum, and/or prostate cancer.

CONCLUSIONS

The metrics to assess the processes and outcomes of patient navigation have been developed for the NCI-sponsored PNRP. If the metrics are found to be valid and reliable, they may prove useful to other investigators.

Patient navigation: state of the art or is it science?

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.

Social determinants of Black-White disparities in breast cancer mortality: a review

Despite the recent decline in breast cancer mortality, African American women continue to die from breast cancer at higher rates than do White women. Beyond the fact that breast cancer tends to be a more biologically aggressive disease in African American than in White women, this disparity in breast cancer mortality also reflects social barriers that disproportionately affect African American women. These barriers hinder cancer prevention and control efforts and modify the biological expression of disease. The present review focuses on delineating social, economic, and cultural factors that are potentially responsible for Black-White disparities in breast cancer mortality. This review was guided by the social determinants of health disparities model, a model that identifies barriers associated with poverty, culture, and social injustice as major causes of health disparities. These barriers, in concert with genetic, biological, and environmental factors, can promote differential outcomes for African American and White women along the entire breast cancer continuum, from screening and early detection to treatment and survival. Barriers related to poverty include lack of a primary care physician, inadequate health insurance, and poor access to health care. Barriers related to culture include perceived invulnerability, folk beliefs, and a general mistrust of the health care system. Barriers related to social injustice include racial profiling and discrimination. Many of these barriers are potentially modifiable. Thus, in addition to biomedical advancements, future efforts to reduce disparities in breast cancer mortality should address social barriers that perpetuate disparities among African American and White women in the United States.

Racial/ethnic disparities in time to follow-up after an abnormal mammogram

BACKGROUND

Although non-Hispanic white women have an increased risk of developing breast cancer, the disease-specific survival is lower for African American and Hispanic women. Little is known about disparities in follow-up after an abnormal mammogram. The goal of this study was to investigate potential disparities in follow-up after an abnormal mammogram.

METHODS

A retrospective cohort study of 6722 women with an abnormal mammogram and documented follow-up from January 2000 through December 2002 was performed at an academic medical center in New York City. The outcome was the number of days between the abnormal mammogram and follow-up imaging or biopsy. Cox proportional hazards models were used to assess the effect of race/ethnicity and other potential covariates.

RESULTS

The median number of days to diagnostic follow-up after an abnormal mammogram was greater for African American (20 days) and Hispanic (21 days) women compared with non-Hispanic white (14 days) women (p < 0.001). Racial/ethnic disparities remained significant in a multivariable model controlling for age, Breast Imaging Reporting and Data System (BIRADS) category, insurance status, provider practice location, and median household income.

CONCLUSIONS

After an abnormal mammogram, African American and Hispanic women had longer times to diagnostic follow-up compared with non-Hispanic white women. Future efforts will focus on identifying the barriers to follow-up so that effective interventions may be implemented.

Implementing colorectal cancer screening in community health centers: addressing cancer health disparities through a regional cancer collaborative

BACKGROUND

The population served by Federally Qualified Health Centers (FQHCs) has lower levels of cancer screening compared with the general population and suffers a disproportionate cancer burden. To address these disparities, 3 federal agencies and a primary care association established and tested the feasibility of a Regional Cancer Collaborative (RCC) in 2005.

METHODS

RCC faculty implemented a learning model to improve cancer screening across 4 FQHCs that met explicit organizational readiness criteria. Regional faculty trained "care process leaders," who worked with primary care teams to plan and implement practice changes. FQHCs monitored progress across the following measures of screening implementation: self-management goal-setting; number and percent screened for breast, cervical, and colorectal cancer; percent timely results notification; and percent abnormal screens evaluated within 90 days. Progress and plans were reviewed in regular teleconferences. FQHCs were encouraged to create local communities of practice (LCOP) involving community resources to support cancer screening and to participate in a monthly teleconference that linked the LCOPs into a regional community of practice. Summary reports and administrative data facilitated a process evaluation of the RCC. chi test and test of trends compared baseline and follow-up screening rates.

RESULTS

The RCC taught the collaborative process using process leader training, teleconferences, 2 regional meetings, and local process improvement efforts. All organizations created clinical tracking capabilities and 3 of the 4 established LCOPs, which met monthly in an regional community of practice. Screening documentation increased for all 3 cancers from 2005 to 2007. Colorectal cancer screening increased from 8.6% to 21.2%.

CONCLUSIONS

A regional plan to enable collaborative learning for cancer screening implementation is feasible, and improvements in screening rates can occur among carefully selected organizations.

Characteristics of the original patient navigation programs to reduce disparities in the diagnosis and treatment of breast cancer

BACKGROUND

Patient navigation is an intervention developed to reduce disparities in cancer care that is being widely replicated and receiving considerable support for demonstration projects and research to test its effectiveness. In the current study, the authors present an in-depth descriptive analysis of the original patient navigation programs to inform current and future program development.

METHODS

A qualitative multistakeholder case study using interviews and site visits of the first patient navigation site and 2 sites subsequently developed by the leadership of the original site were evaluated.

RESULTS

At these sites, patient navigation is a system, as opposed to a person, comprised primarily of navigators and directors that work together to remove barriers and facilitate access in a well-defined course of care; navigators were from the community or were culturally similar to the patient population served but were also paid employees of the clinical care site with detailed knowledge of the clinical course patients must traverse to complete care plans. Directors had administrative authority over the clinical facility and social capital across institutions, and communicated regularly and openly with navigators to implement system level changes to remove barriers to care. Contextual factors such as policies supporting breast cancer care also influenced the implementation of these programs.

CONCLUSIONS

The first patient navigation programs combined community and culturally sensitive care-coordination with aspects of disease management programs to reduce racial, ethnic, and poverty-driven disparities in care. Future efforts to replicate and evaluate patient navigation should take into account these unique aspects of the original patient navigation programs.

Follow-up of abnormal screening mammograms among low-income ethnically diverse women: findings from a qualitative study

OBJECTIVE

To understand factors that women feel facilitate or hinder their receipt of diagnostic services following an abnormal screening mammogram.

METHODS

This qualitative study used a purposive sampling strategy to identify low-income, ethnically diverse women aged 40 or over who had a recent abnormal mammogram. Working with a community health center, breast evaluation center, and mobile mammography van, 64 women were interviewed to identify salient themes that differentiated women who received timely follow-up from those who did not.

RESULTS

Prominent themes among women who delayed follow-up included dissatisfaction with communication of results; perceived disrespect on the part of providers and clinic staff; logistical barriers to access of diagnostic services; anxiety and fear about a possible cancer diagnosis; and a lack of information about breast cancer screening and symptoms. Women who received timely care more often reported an appreciation of efforts by providers and clinic staff to support their prompt follow-up; availability of social support that facilitated appointment-keeping; confidence in their ability to advocate for their health; and a high priority placed on self-care.

CONCLUSION

A comprehensive approach to improving timely diagnostic follow-up among underserved groups must address patient beliefs and attitudes, provider practices and communication, and practices at the health care systems level.

PRACTICE IMPLICATIONS

Implications and strategies for improving patient education, patient-provider communication, and organizational practices are discussed.

Predictors and barriers to timely medical follow-up after cardiovascular disease risk factor screening according to race/ethnicity

BACKGROUND

The purpose of this study was to assess followup practices among individuals found to have elevated cardiovascular disease (CVD) risk factors in a screening and educational outreach.

METHODS

Participants in the National Heart, Lung and Blood Institute Family Intervention Trial for Heart Health (FIT Heart) who were found to have hypertension, prehypertension, suboptimal lipids and/or abnormal blood glucose were included in this study (N = 214, mean age 49 +/- 13, 64% female, 33% nonwhite). Contact was made at two weeks, six weeks and three months to determine if medical follow-up was initiated. Barriers to nonadherence were assessed.

RESULTS

After two weeks, significantly more whites had medical follow up compared to nonwhites (34% vs. 20%, p = 0.04). Racial/ethnic minorities were more likely to report that not having a doctor was a barrier (30% vs. 11%, p = 0.02). Non-whites were more likely to return to the study staff for followup rather than an outside physician (32% vs. 15%, p = 0.001).

CONCLUSION

Racial/ethnic minorities with elevated CVD risk factors may have delayed medical follow-up compared to whites, and this may be attributable to lack of access to a doctor. These data suggest that improving access to care may reduce racial/ethnic disparities in risk factor management and CVD outcomes.

Barriers to screening colonoscopy for low-income Latino and white patients in an urban community health center

BACKGROUND

Colonoscopy is a screening modality for the early detection of colonic polyps and cancers but is underutilized, particularly among minorities.

OBJECTIVE

To identify potential barriers to screening colonoscopy among low income Latino and white non-Latino patients in an urban community health center. DESIGN, PARTICIPANTS, AND APPROACH: We conducted semistructured interviews with a convenience sample of patients 53 to 70 years old, eligible for colorectal cancer screening that spoke English or Spanish. Open-ended questions explored knowledge, beliefs, and experience with or reasons for not having screening colonoscopy. We performed content analysis of transcripts using established qualitative techniques.

RESULTS

Of 40 participants recruited, 57% were women, 55% Latino, 20% had private health insurance, and 40% had a prior colonoscopy. Participants described a wide range of barriers categorized into 5 major themes: (1) System barriers including scheduling, financial, transportation, and language difficulties; (2) Fear of pain or complications of colonoscopy and fear of diagnosis (cancer); (3) Lack of desire or motivation, including "laziness" and "procrastination"; (4) Dissuasion by others influencing participants' decision regarding colonoscopy; and (5) Lack of provider recommendation including not hearing about colonoscopy or not understanding the preparation instructions.

CONCLUSIONS

Understanding of the range of barriers to colorectal cancer screening can help develop multimodal interventions to increase colonoscopy rates for all patients including low-income Latinos. Interventions including systems improvements and navigator programs could address barriers by assisting patients with scheduling, insurance issues, and transportation and providing interpretation, education, emotional support, and motivational interviewing.

Patient, caregiver, and health care practitioner knowledge of, beliefs about, and attitudes toward epilepsy

The medical literature related to knowledge of, beliefs about, and attitudes toward epilepsy was reviewed from the perspective of patients, caregivers, and health care providers. The literature points to a desire for enhanced epilepsy education by patients and caregivers; however, these needs have not been met by primary or specialty care. Surveys of general practitioners (GPs) point to limitations in knowledge and negative attitudes. GPs view their role in epilepsy care as primarily educational and tend to acknowledge their limitations by referring difficult cases. Ongoing education for GPs is important, as is an improved partnership in defining roles for care and education. Health care professionals specialized in epilepsy care acknowledge their own set of barriers to optimal care. Epilepsy education programs have been able to improve knowledge; however, long-term improvements in behavioral outcomes or quality of life are less documented. Suggestions for improvements are provided.

A program to enhance completion of screening colonoscopy among urban minorities

BACKGROUND & AIMS

Although colonoscopy is becoming the preferred screening test for colorectal cancer, screening rates, particularly among minorities, are low. Little is known about the uptake of screening colonoscopy or the factors that predict colonoscopy completion among minorities. This study investigated the use of patient navigation within an open-access referral system and its effects on colonoscopy completion rates among urban minorities.

METHODS

This was a cohort study that took place at a teaching hospital in New York. Participants were mostly African Americans and Hispanics directly referred for screening colonoscopy by primary care clinics from November 2003 to May 2006. Once referred, a bilingual Hispanic female patient navigator facilitated the colonoscopy completion. Completion rates, demographic factors associated with completing colonoscopy, endoscopic findings, and patient satisfaction were analyzed.

RESULTS

Of 1169 referrals, 688 patients qualified for and 532 underwent navigation. Two thirds (66%) of navigated patients completed screening colonoscopies, 16% had adenomas, and only 5% had inadequate bowel preps. Women were 1.31 times more likely to complete the colonoscopy than men (P = .014). Hispanics were 1.67 times more likely to complete the colonoscopy than African Americans (P = .013). Hispanic women were 1.50 times more likely to complete the colonoscopy than Hispanic men (P = .009). Patient satisfaction was 98% overall, with 66% reporting that they definitely or probably would not have completed their colonoscopy without navigation.

CONCLUSIONS

By using a patient navigator, the majority of urban minorities successfully completed their colonoscopies, clinically significant pathology was detected, and patient satisfaction was enhanced. This approach may help increase adherence with screening colonoscopy efforts in other clinical settings.

Timing is everything: methodologic issues locating and recruiting medically underserved women for abnormal mammography follow-up research

OBJECTIVES

Recruiting underserved women in breast cancer research studies remains a significant challenge. We present our experience attempting to locate and recruit minority and medically underserved women identified in a Nashville, Tennessee public hospital for a mammography follow-up study.

STUDY DESIGN

The study design was a retrospective hospital-based case-control study.

METHODS

We identified 227 women (88 African-American, 65 Caucasian, 36 other minority, 38 race undocumented in the medical record) who had undergone screening mammography and received an abnormal result during 2003-2004. Of the 227 women identified, 159 women were successfully located with implementation of a tracking protocol and more rigorous attempts to locate the women using online directory assistance and public record search engines. Women eligible for the study were invited to participate in a telephone research survey. Study completion was defined as fully finishing the telephone survey.

RESULTS

An average of 4.6 telephone calls (range 1-19) and 2.7 months (range 1-490 days) were required to reach the 159 women contacted. Within three contact attempts, more cases were located than controls (61% cases vs. 49% controls, p=0.03). African-American women cases were four times likely to be recruited than African-American controls, (OR, 4.07; 95% CI, 1.59-10.30) (p=0.003). After 3 months of effort, we located 67% of African-American women, 63% of Caucasian women, and 56% of other minorities. Ultimately, after a maximum of 12 attempts to contact women, 77% of African-American women and 71% of Caucasian women were eventually found. Of these, 59% of African-American women, 69% Caucasian women, and 50% other minorities were located and completed the study survey for an overall response rate of 59%, 71%, and 47% respectively.

CONCLUSIONS

Data collection and study recruitment efforts were more challenging in racial and ethnic minorities. Continuing attempts to contact women may increase minority group study participation but does not guarantee retention or study completion.

Overcoming poor attendance to first scheduled colonoscopy: a randomized trial of peer coach or brochure support

OBJECTIVES

Among patients unlikely to attend a scheduled colonoscopy, we examined the impact of peer coach versus educational brochure support and compared these with concurrent patients who did not receive support.

METHODS

From health system data, we identified 275 consecutive patients aged >50 who kept <75% of visits to 4 primary care practices and scheduled for a first colonoscopy from February 1, 2005 to August 31, 2006. Using block randomization, we assigned consenting patients to a phone call by a peer coach trained to address barriers to attendance or to a mailed colonoscopy brochure. Study data came from electronic medical records. Odds ratios of colonoscopy attendance were adjusted for demographic, clinical, and health care factors.

RESULTS

Colonoscopy attendance by the peer coach group (N = 70) and brochure group (N = 66) differed by 11% (68.6% vs 57.6%, respectively). Compared with the brochure group, the peer coach group had over twofold greater adjusted odds ratio (AOR) of attendance (2.14, 95% confidence interval [CI] = 0.99-4.63) as did 49 patients who met the prespecified criteria for needing no support (2.68, 95% CI = 1.05-6.82) but the AORs did not differ significantly for 41 patients who declined support (0.61, 95% CI = 0.25-1.45) and 49 patients who could not be contacted (0.85, 95% CI = 0.36-2.02). Attendance was less likely for black versus white race (AOR = 0.37, 95% CI = 0.19-0.72) but more likely for patients with high versus low primary care visit adherence (AOR = 2.30, 95% CI = 1.04-5.07).

CONCLUSION

For patients who often fail to keep appointments, peer coach support appears to promote colonoscopy attendance more than an educational brochure.

Using community-based research methods to design cancer patient navigation training

BACKGROUND

Cancer mortality continues to be higher in Native Hawaiians than whites, and research has identified numerous barriers to good cancer care. Cancer navigator programs provide individualized assistance to patients and family members to overcome barriers, promoting early diagnosis and timely and complete treatment.

OBJECTIVES

Our purpose was to design a training curriculum to provide community-based outreach workers serving Native Hawaiians with cancer patient navigator skills.

METHODS

The Ho'okele i ke Ola (Navigating to Health) curriculum was informed by data gathered from Native Hawaiian cancer patients and their family members, outreach workers in Native Hawaiian communities, and cancer care providers. Based on findings, the 48-hour curriculum focused on cancer knowledge, cancer resources, and cancer communications. Three versions were developed: (1) six days of training and on-site tours in urban Honolulu; (2) four days of training on a neighbor island, with 2 days of on-site tours in Honolulu; and (3) a 3-credit community college independent study course. Graduates were interviewed after each session and 3 months after graduation about application of navigation skills.

RESULTS

In 18 months, 62 health workers from community-based, clinical, and community college settings were trained -31 in Honolulu-based trainings, 29 in neighbor island trainings where earlier graduates served as co-faculty, and 2 through Maui Community College (MCC). Follow-up data suggest increased knowledge, skills, capacity, and feelings of competence among trainees.

CONCLUSIONS

All three versions of the Ho'okele i ke Ola curriculum, developed with community input, have proven successful in increasing cancer patient navigation skills of trainees.

The effect of patient navigation on time to diagnosis, anxiety, and satisfaction in urban minority women with abnormal mammograms: a randomized controlled trial

Delay in follow-up after an abnormal mammogram is associated with advanced disease stage, poorer survival, and increased anxiety. Despite the implementation of many patient navigator programs across the country, there are few published, peer-reviewed studies documenting its effectiveness. We tested the effectiveness of a patient navigator in improving timeliness to diagnosis, decreasing anxiety, and increasing satisfaction in urban minority women after an abnormal mammogram. Women with suspicious mammograms were randomly assigned to usual care (N=50) or usual care plus intervention with a patient navigator (N=55). There were no demographic differences between the two groups. Women in the intervention group had shorter times to diagnostic resolution (mean 25.0 vs. 42.7 days; p=.001), with 22% of women in the control group without a final diagnosis at 60 days vs. 6% in the intervention group. The intervention group also had lower mean anxiety scores (decrease of 8.0 in intervention vs. increase of 5.8 in control; p<.001), and higher mean satisfaction scores (4.3 vs. 2.9; p<.001). Patient navigation is an effective strategy to improve timely diagnostic resolution, significantly decrease anxiety, and increase patient satisfaction among urban minority women with abnormal mammograms.

Pathways to breast cancer diagnosis and treatment: exploring the social relations of diagnostic delay

In epidemiological studies, inequitable access to breast cancer care aligns with such variables as income, age, education, ethnicity and residential location. These variables correspond to structural patterns of advantage and disadvantage, which in turn may constrain or facilitate timely access to care. The purpose of this study was to understand the complexities of women's pathways to diagnosis. Thirty-five women from diverse backgrounds and who had clinically detectable breast symptoms at time of diagnosis participated in semi-structured interviews. All were receiving or completing treatment when they participated. Data were analyzed using the strategies of induction, comparison and abduction. All of the participants described a variety of activities involved in seeking care for breast cancer. The findings illustrate how the social relations of health care, rather than simply patient or provider delay, may contribute barriers to timely diagnosis. We illustrate how women's widely differing social and material contexts offer opportunities and barriers to access.

Errors in cancer diagnosis: current understanding and future directions

PURPOSE

Errors in cancer diagnosis are likely the most harmful and expensive types of diagnostic errors. We reviewed the literature to understand the prevalence, origins, and prevention of errors in cancer diagnosis, focusing on common cancers for which early diagnosis offers clear benefit (melanoma and cancers of the breast, colon, and lung).

METHODS

We searched the Cochrane Library and PubMed from 1966 until April 2007 for publications that met our review criteria and manually searched references of key publications. Our search yielded 110 studies, of which nine were prospective studies and the remaining were retrospective studies.

RESULTS

Errors in cancer diagnosis were not uncommon in autopsy studies and were associated with significant harm and expense in malpractice claims. Literature on prevalence was scant. For each type of cancer, we classified preventable errors according to their origins in patient-physician encounters in the clinic setting, diagnostic test or procedure performance, pathologic confirmation of diagnosis, follow-up of patient or test result, or patient-related delays.

CONCLUSION

The literature reflects advanced knowledge of contributory factors and prevention for diagnostic errors related to the performance of procedures and imaging tests and emerging understanding of pathology errors. However, prospective studies are few, as are studies of diagnostic errors arising from the clinical encounter and patient follow-up. Future research should examine further the system and cognitive problems that lead to the many contributory factors we identified, and address interdisciplinary interventions to prevent errors in cancer diagnosis.

Positive impact of a breast-health triaging system on breast-care access and physician satisfaction

OBJECTIVE

Minority patients are at risk for delayed breast cancer treatment. Using nonsurgical breast specialists could improve access but requires appropriate referral to ensure prompt cancer care. Our objective was to evaluate a referral triage system in a combined medical/surgical breast health program (BHP).

METHODS

A triage system based on imaging findings, examination, and patient age was instituted. An advanced practice nurse managed referrals and a prospective database. Referring providers were surveyed after 2 years.

RESULTS

From 2003 to 2006, 4,840 referrals were made to surgeons (57%) and nonsurgeons (43%). Breast cancers were found in 8.5% of patients. Referral error occurred in 4 cancer patients (.1%). BHP-referred patients had significantly shorter times to surgical appointment (10 days) than non-BHP referrals (45 days). A referring provider survey indicated 96% satisfaction.

CONCLUSIONS

A breast-care triage system expedited cancer care resulting in physician satisfaction and increased referrals.

The missing link: improving quality with a chronic disease management intervention for the primary care office

Bold steps are necessary to improve quality of care for patients with chronic diseases and increase satisfaction of both primary care physicians and patients. Office-based chronic disease management (CDM) workers can achieve these objectives by offering self-management support, maintaining disease registries, and monitoring compliance from the point of care. CDM workers can provide the missing link by connecting patients, primary care physicans, and CDM services sponsored by health plans or in the community. CDM workers should be supported financially by Medicare, Medicaid, and commercial health plans through reimbursements to physicians for units of service, analogous to California's Comprehensive Perinatal Services Program. Care provided by CDM workers should be standardized, and training requirements should be sufficiently flexible to ensure wide dissemination. CDM workers can potentially improve quality while reducing costs for preventable hospitalizations and emergency department visits, but evaluation at multiple levels is recommended.
