Using community-engaged methods to develop a study protocol for a cost analysis of a multi-site patient navigation intervention for breast cancer care.

BACKGROUND: Patient navigation is an evidence-based intervention for reducing delays in oncology care among underserved populations. In order to address the financial sustainability of this intervention, information is needed on the cost of implementing patient navigation in diverse healthcare settings. Because patient navigation programs and care settings are highly variable, this paucity of cost data creates difficulties in identifying best practices and decisions about the feasibility of implementing navigation programs within a health care system. One barrier to collecting these cost data is the lack of assessment tools available to support patient navigation programs. These tools must be relevant to the wide variety of navigation activities that exist in health care settings, and be flexible enough to collect cost data important to stakeholders in fee-for-service and value-based care environments. METHODS AND RESULTS: We present a novel approach and methods for assessing the cost of a patient navigation program implemented across six hospital systems to enhance timely entry and uptake of breast cancer care and treatment. These methods and tools were developed in partnership with breast oncology patient navigators and supervisors using principles of stakeholder engagement, with the goal of increasing usability and feasibility in the field. CONCLUSIONS: This methodology can be used to strengthen cost analysis and assessment tools for other navigation programs for improving care and treatment for patients with chronic conditions. TRIAL REGISTRATION: NCT03514433.

Patient navigation to address sociolegal barriers for patients with cancer: A comparative-effectiveness study.

BACKGROUND: Sociolegal barriers to cancer care are defined as health-related social needs like affordable healthy housing, stable utility service, and food security that may be remedied by public policy, law, regulation, or programming. Legal support has not been studied in cancer care. METHODS: The authors conducted a randomized controlled trial of patients who had newly diagnosed cancer at a safety-net medical center in Boston from 2014 through 2017, comparing standard patient navigation versus enhanced navigation partnered with legal advocates to identify and address sociolegal barriers. English-speaking, Spanish-speaking, or Haitian Creole-speaking patients with breast and lung cancer were eligible within 30 days of diagnosis. The primary outcome was timely treatment within 90 days of diagnosis. Secondary outcomes included patient-reported outcomes (distress, cancer-related needs, and satisfaction with navigation) at baseline and at 6 months. RESULTS: In total, 201 patients with breast cancer and 19 with lung cancer enrolled (response rate, 78%). The mean patient age was 55 years, 51% of patients were Black and 22% were Hispanic, 20% spoke Spanish and 8% spoke Haitian Creole, 73% had public health insurance, 77% reported 1 or more perceived sociolegal barrier, and the most common were barriers to housing and employment. Ninety-six percent of participants with breast cancer and 73% of those with lung cancer initiated treatment within 90 days. No significant effect of enhanced navigation was observed on the receipt of timely treatment among participants with breast cancer (odds ratio, 0.88; 95% CI, 0.17-4.52) or among those with lung cancer (odds ratio, 4.00; 95% CI, 0.35-45.4). No differences in patient-reported outcomes were observed between treatment groups. CONCLUSIONS: Navigation enhanced by access to legal consultation and support had no impact on timely treatment, patient distress, or patient needs. Although most patients reported sociolegal barriers, few required intensive legal services that could not be addressed by navigators. LAY SUMMARY: In patients with cancer, the experience of sociolegal barriers to care, such as unstable housing, utility services, or food insecurity, is discussed. Addressing these barriers through legal information and assistance may improve care. This study compares standard patient navigation versus enhanced navigation partnered with legal advocates for patients with breast and lung cancers. Almost all patients in both navigation groups received timely care and also reported the same levels of distress, needs, and satisfaction with navigation. Although 75% of patients in the study had at least 1 sociolegal barrier identified, few required legal advocacy beyond what a navigator who received legal information and coaching could provide.

Communicating to Engage: An Improvisational Theater-Based Communication Training Designed to Support Community-Academic Partnership Development.

PROBLEM: The potential for community-engaged research to address health inequity requires deliberate effort to create trusting and equitable community-academic partnerships. A lack of evidence-based opportunities for cultivating such partnerships remains a barrier. APPROACH: In 2017 and 2018, the authors designed, facilitated, and evaluated a mixed stakeholder training, Communicating to Engage, at 2 urban academic medical centers involved in the All of Us research program, Boston Medical Center and Mass General Brigham. The goal was to bring together researchers and community members to develop communication skills through improvisational theater-based co-learning. The curriculum was inspired by several evidence-based learning frameworks including community-based participatory research principles and improvisational theater techniques. A self-administered survey completed before and after the training session measured participants' communication skills using the Self-Perceived Communication Competence Scale (SPCCS) and comfort with specific communication styles as outlined in the program's training objectives. Paired t tests were used to measure changes in scaled responses among combined participants and separately among self-identified community members and researchers. OUTCOMES: Sixty-nine total participants across 6 workshops completed training evaluations. Overall, pre-post survey analysis demonstrated significant mean score improvement for both the SPCCS and comfort with specific communication styles. In stratified analysis, both community members (n = 26) and researchers (n = 38) reported significant improvement in scores related to comfort with specific communication styles. Only researchers, but not community members, had significant improvement in SPCCS scores. NEXT STEPS: The Communicating to Engage program brought community and researcher stakeholders together and demonstrated improvement in self-perceived communication styles, yet researcher participants benefited more than community participants. Future innovation is necessary to further target community stakeholder communication training needs. Mixed stakeholder improvisational theater-based learning provides deliberate opportunities to build new community-academic partnerships that may enhance health equity initiatives.

Brain-Derived neurotrophic factor Val66Met induces female-specific changes in impulsive behaviour and alcohol self-administration in mice.

Substance use disorders are a debilitating neuropsychiatric condition, however it remains unclear why some individuals are at greater risk of substance use disorders than others and what genetic factors determine such individual differences. Impulsivity appears a promising candidate endophenotype to bridge the gap between genetic risk and addiction. Brain-derived neurotrophic factor (BDNF), and in particular the BDNFVal66Met polymorphism, has been suggested to be involved in both impulsivity and substance use disorders, however results so far have been inconsistent. To investigate the role of BDNF, and more specifically the BDNFVal66Met polymorphism, in both impulsivity and operant alcohol self-administration using the same animal model. Separate cohorts of humanized Val66Met transgenic mice were assessed for either trait impulsivity in the 5-choice serial reaction time (5-CSRT) touchscreen task, or propensity towards obtaining ethanol in an operant paradigm. It was found that female hBDNFVal/Val mice exhibited both greater impulsivity compared to hBDNFMet/Met mice of the same sex as shown by a higher number of premature responses at one of three increased inter-trial intervals tested in the 5-CSRT task, and a greater propensity toward stable ethanol self-administration relative to male mice of the same genotype in the operant paradigm. By contrast, male mice showed no difference between genotypes in impulsivity or stable ethanol self-administration. The hBDNFMet/Met genotype appears to sex-specifically alter aspects of both impulsive behaviour and addiction propensity. These results suggest that impulse behaviour may be a possible predictor of addiction risk.

Translating research into practice: Protocol for a community-engaged, stepped wedge randomized trial to reduce disparities in breast cancer treatment through a regional patient navigation collaborative.

BACKGROUND: Racial and socioeconomic disparities in breast cancer mortality persist. In Boston, MA, Black, Non-Hispanic women and Medicaid-insured individuals are 2-3 times more likely to have delays in treatment compared to White or privately insured women. While evidence-based care coordination strategies for reducing delays exist, they are not systematically implemented across healthcare settings. METHODS: Translating Research Into Practice (TRIP) utilizes community engaged research methods to address breast cancer care delivery disparities. Four Massachusetts Clinical and Translational Science Institute (CTSI) hubs collaborated with the Boston Breast Cancer Equity Coalition (The Coalition) to implement an evidence-based care coordination intervention for Boston residents at risk for delays in breast cancer care. The Coalition used a community-driven process to define the problem of care delivery disparities, identify the target population, and develop a rigorous pragmatic approach. We chose a cluster-randomized, stepped-wedge hybrid type I effectiveness-implementation study design. The intervention implements three evidence-based strategies: patient navigation services, a shared patient registry for use across academic medical centers, and a web-based social determinants of health platform to identify and address barriers to care. Primary clinical outcomes include time to first treatment and receipt of guideline-concordant treatment, which are captured through electronic health records abstraction. We will use mixed methods to collect the secondary implementation outcomes of acceptability, adoption/penetration, fidelity, sustainability and cost. CONCLUSION: TRIP utilizes an innovative community-driven research strategy, focused on interdisciplinary collaborations, to design and implement a translational science study that aims to more efficiently integrate proven health services interventions into clinical practice.

Health Literacy, Language, and Cancer-Related Needs in the First 6 Months After a Breast Cancer Diagnosis.

PURPOSE: Low health literacy (HL) and language negatively affect cancer screening and prevention behaviors; less is known about how they affect the patient's experience during cancer treatment. This study explores associations among HL, spoken language, and dimensions of cancer-related needs within 6 months of receiving a breast cancer diagnosis. METHODS: Women speaking English, Spanish, or Haitian Creole, enrolled in a patient navigation study at diagnosis, completed a survey in their primary spoken language at baseline and 6 months to characterize their cancer-related needs. HL was measured using the Brief Health Literacy Screening Tool. Outcomes included the Cancer Needs Distress Inventory (CaNDI; n = 38 items) and the Communication and Attitudinal Self-Efficacy scale (CASE-Cancer) for cancer (n = 12 items). Linear regressions measured the impact of HL and language on total CaNDI and CASE-Cancer scale for cancer scores and subscales, adjusted for demographics. RESULTS: At baseline, 262 women participated and 228 (87%) followed up at 6 months. Of these, 38% had adequate HL, 33% had marginal HL, and 29% had inadequate HL. Women with inadequate or marginal HL had higher median baseline CaNDI scores (P = .02) and lower self-efficacy scores (P = .008), relative to those with adequate HL. Haitian-Creole speakers had significantly lower CANDI scores at baseline (P = .03). Adjusting for demographics, differences in CaNDI scores at baseline remained significant for those with lower HL and Haitian-Creole speakers. At 6 months, differences in self-efficacy persisted for Haitian-Creole speakers. CONCLUSION: Findings suggest that interventions oriented to mitigating HL and language barriers might reduce distress at the time of diagnosis and improve self-efficacy over the course of treatment.

Connecting Community to Research: A Training Program to Increase Community Engagement in Research.

BACKGROUND: The Boston University Clinical & Translational Science Institute (BU CTSI) identified a local need to increase the capacity of members of a diverse inner-city community with no prior knowledge of research to partner with researchers along the research continuum. OBJECTIVES: To design, implement, and evaluate an introductory- level capacity-building training using community pedagogy and providing information about current research and opportunities to partner with local researchers. METHODS: Guided by two advisory boards of community-engaged professionals and patients, the community engagement team of the BU CTSI designed, implemented, and evaluated the Connecting Community to Research (CCR) training program. We targeted existing community groups in Boston interested in partnering with an academic institution to advance the health of their community. Interactive trainings focused on principles of community-engaged research (CEnR), and how individual experiences might influence research. Each session offered real-time opportunities for participants to engage with local researchers on existing research such as joining a local research advisory group or institutional review board. Self-administered surveys captured participant experiences. CONCLUSIONS: Over 1 year, we trained 100 community members and almost all participants felt that the objectives of the training program were met and the information was relevant. More than 50% of the participants took advantage of partnership opportunities with local researchers. A toolkit was designed and disseminated to support others to replicate the program. We demonstrated that an interactive training curriculum designed with a community-engaged pedagogy and supported by opportunities for engagement has the ability to successfully partner community members with academic researchers.

Social Network Structures of Breast Cancer Patients and the Contributing Role of Patient Navigators.

BACKGROUND: Minority women in the U.S. continue to experience inferior breast cancer outcomes compared with white women, in part due to delays in care delivery. Emerging cancer care delivery models like patient navigation focus on social barriers, but evidence demonstrating how these models increase social capital is lacking. This pilot study describes the social networks of newly diagnosed breast cancer patients and explores the contributing role of patient navigators. MATERIALS AND METHODS: Twenty-five women completed a one hour interview about their social networks related to cancer care support. Network metrics identified important structural attributes and influential individuals. Bivariate associations between network metrics, type of network, and whether the network included a navigator were measured. Secondary analyses explored associations between network structures and clinical outcomes. RESULTS: We identified three types of networks: kin-based, role and/or affect-based, or heterogeneous. Network metrics did not vary significantly by network type. There was a low prevalence of navigators included in the support networks (25%). Network density scores were significantly higher in those networks without a navigator. Network metrics were not predictive of clinical outcomes in multivariate models. CONCLUSION: Patient navigators were not frequently included in support networks, but provided distinctive types of support. If navigators can identify patients with poorly integrated (less dense) social networks, or who have unmet tangible support needs, the intensity of navigation services could be tailored. Services and systems that address gaps and variations in patient social networks should be explored for their potential to reduce cancer health disparities. IMPLICATIONS FOR PRACTICE: This study used a new method to identify the breadth and strength of social support following a diagnosis of breast cancer, especially examining the role of patient navigators in providing support. While navigators were only included in one quarter of patient support networks, they did provide essential supports to some individuals. Health care providers and systems need to better understand the contributions of social supports both within and outside of health care to design and tailor interventions that seek to reduce health care disparities and improve cancer outcomes.

Impact of patient and navigator race and language concordance on care after cancer screening abnormalities.

BACKGROUND: Patient navigation improves the timely diagnosis of cancer among minorities, but little is known about the effects of patient and navigator race and language concordance on health outcomes. METHODS: The authors investigated the effects of patient and navigator race and language concordance on the time to diagnosis of cancer screening abnormalities among participants in the Boston Patient Navigation Research Program, a clinical effectiveness trial for women who had breast or cervical cancer screening abnormalities identified from January 1, 2007 to December 31, 2008. Hazard ratios and 95% confidence intervals were estimated using proportional hazards regression adjusting for clinical and demographic factors. RESULTS: In total, 1257 women had breast cancer screening abnormalities (n = 655) or cervical cancer screening abnormalities (n = 602) identified, and 56% were nonwhite. Language concordance was associated with timelier resolution for all patients in the cervical cancer screening abnormalities group during the first 90 days (adjusted hazard ratio, 1.46; 95% confidence interval, 1.18-1.80), and specifically for Spanish speakers during the first 90 days (adjusted hazard ratio, 1.43; 95% confidence interval, 1.10-1.84), but no difference was observed after 90 days for women who had cervical cancer screening abnormalities or at any time for those who had breast cancer screening abnormalities. Race concordance was associated with significant decreases in the time to diagnosis for minority women with breast and cervical cancer screening abnormalities in analyses stratified by race, but no differences were observed in analyses that included all women. CONCLUSIONS: Patient navigator race and language concordance improved the timeliness of care in a minority population. Patient navigators who are racially/ethnically diverse and multilingual may help address barriers to care and improve cancer outcomes for low-income minorities.

Multiple barriers delay care among women with abnormal cancer screening despite patient navigation.

BACKGROUND: While there is widespread dissemination of patient navigation programs in an effort to reduce delays in cancer care, little is known about the impact of barriers to care on timely outcomes. METHODS: We conducted a secondary analysis of the Boston Patient Navigation Research Program (PNRP) to examine the effect that the presence of barriers had on time to diagnostic resolution of abnormal breast or cervical cancer screening tests. We used multivariable Cox proportional hazards regression with time to diagnostic resolution as the outcome to examine the effect of the number of barriers, controlling for demographic covariates and clustered by patients' primary navigator. RESULTS: There were 1481 women who received navigation; mean age was 39 years; 32% were White, 27% Black, and 31% Hispanic; 28% had private health insurance; and 38% did not speak English. Overall, half (n=745, 50%) had documentation of one or more barriers to care. Women with barriers were more likely to be older, non-White, non-English language speakers, and on public or no health insurance compared with women without barriers. In multivariable analyses, we found less timely diagnostic resolution as the number of barriers increased (one barrier, adjusted hazard ratio [aHR] 0.81 [95% CI 0.56-1.17], p=0.26; two barriers, aHR 0.55 [95% CI 0.37-0.81], p=0.0025; three or more barriers, aHR 0.31 [95% CI 0.21-0.46], p<0.0001)]. CONCLUSION: Within a patient navigation program proven to reduce delays in care, we found that navigated patients with documented barriers to care experience less timely resolution of abnormal cancer screening tests.

Feasibility of patient navigation in resident primary care practice: a screening mammography quality improvement initiative.

Patient navigation (PN) has been used to improve breast cancer outcomes but has not been evaluated in resident practices. The objective of this study was to evaluate the feasibility of PN in resident clinics to improve biennial screening mammography. All participants whose last screening mammogram was at 18 months or after received PN. Feasibility outcomes included practicality (ability to carry out intervention), effectiveness (ability of intervention to increase biennial screening mammography rates), and acceptability (resident satisfaction with PN). Despite difficulty contacting patients, we found PN improved screening mammography adherence in resident practices serving vulnerable populations. Adherence rates increased significantly postintervention. Residents reported interest in using PN in practice.

The impact of health insurance reform on insurance instability.

We investigated the impact of the 2006 Massachusetts health care reform on insurance coverage and stability among minority and underserved women. We examined 36 months of insurance claims among 1,946 women who had abnormal cancer screening at six community health centers pre-(2004-2005) and post-(2007-2008) insurance reform. We examined frequency of switches in insurance coverage as measures of longitudinal insurance instability. On the date of their abnormal cancer screening test, 36% of subjects were publicly insured and 31% were uninsured. Post-reform, the percent ever uninsured declined from 39% to 29% (p .001) and those consistently uninsured declined from 23% to 16%. To assess if insurance instability changed between the pre- and post-reform periods, we conducted Poisson regression models, adjusted for patient demographics and length of time in care. These revealed no significant differences from the pre- to post-reform period in annual rates of insurance switches, incident rate ratio 0.98 (95%- CI 0.88-1.09). Our analysis is limited by changes in the populations in the pre- and post-reform period and inability to capture care outside of the health system network. Insurance reform increased stability as measured by decreasing uninsured rates without increasing insurance switches.

The impact of insurance coverage during insurance reform on diagnostic resolution of cancer screening abnormalities.

We examined the impact of Massachusetts insurance reform on the care of women at six community health centers with abnormal breast and cervical cancer screening to investigate whether stability of insurance coverage was associated with more timely diagnostic resolution. We conducted Cox proportional hazards models to predict time from cancer screening to diagnostic resolution, examining the impact of 1) insurance status at time of screening abnormality, 2) number of insurance switches over a three-year period, and 3) insurance history over a three-year period. We identified 1,165 women with breast and 781 with cervical cancer screening abnormalities. In the breast cohort, Medicaid insurance at baseline, continuous public insurance, and losing insurance predicted delayed resolution. We did not find these effects in the cervical cohort. These data provide evidence that stability of health insurance coverage with insurance reform nationally may improve timely care after abnormal cancer screening in historically underserved women.

Impact of depression on the intensity of patient navigation for women with abnormal cancer screenings.

Patient navigation is increasingly being used to support vulnerable patients to receive timely and quality medical care. We sought to understand whether patients with depression utilize additional patient navigation services after abnormal cancer screening. We compared depressed and non-depressed women using three different measures of intensity of patient navigation: number of patient-navigator encounters, encounter time, and number of unique barriers to care. The study population consisted of 1,455 women who received navigation after abnormal screening for breast or cervical cancer at one of six community health centers in Boston. Navigators spent a median of 60-75 minutes over one or two encounters per participant, with 49% of participants having one or more documented barrier to care. Depressed women did not differ in total numbers of encounters, encounter time, or unique barriers compared with non-depressed women. Our findings suggest that pre-existing depression does not predict which women will utilize additional navigation services.

Social service barriers delay care among women with abnormal cancer screening.

BACKGROUND: Inequity in cancer outcomes for minorities and vulnerable populations has been linked to delays in cancer care that arise from barriers to accessing care. Social service barriers represent those obstacles related to meeting life's most basic needs, like housing and income, which are often supported by public policy, regulation and services. OBJECTIVE: To examine the association between social service barriers and timely diagnostic resolution after a cancer screening abnormality. DESIGN: Secondary analysis of the intervention arm of Boston Patient Navigation Research Program (2007-2008) conducted across six urban community health centers. Subjects with no barriers, other barriers, and social service barriers were compared on their time to diagnostic resolution. SUBJECTS: Women ≥ 18 years of age with a breast or cervical cancer screening abnormality. MAIN MEASURES: Social service barriers included: income supports, housing and utilities, education and employment, and personal/family stability and safety. Time to event analyses compared across five groups: those with no barriers, one barrier (other), one barrier (social service), two or more barriers (all other), and two or more barriers (at least one social service). KEY RESULTS: 1,481 navigated women; 31 % Hispanic, 27 % Black, 32 % White; 37 % non-English speakers and 28 % had private health insurance. Eighty-eight women (6 %) had social service barriers. Compared to those without social service barriers, those with were more likely to be Hispanic, younger, have public/no health insurance, and have multiple barriers. Those with two or more barriers (at least one social service barrier), had the longest time to resolution compared to the other four groups (aHR resolution < 60 days = 0.27, ≥ 60 days = 0.37). CONCLUSION: Vulnerable women with multiple barriers, when at least one is a social service barrier, have delays in care despite navigation. The impact of patient navigation may never be fully realized if social service barriers persist without being identified or addressed.

Challenges in the delivery of quality breast cancer care: initiation of adjuvant hormone therapy at an urban safety net hospital.

PURPOSE: Breast cancer treatment disparities in racial/ethnic minority and low-income populations are well documented; however, underlying reasons remain poorly understood. This study sought to identify barriers to the delivery of quality breast cancer treatment, addressing compliance with the National Quality Forum (NQF) quality metric for adjuvant hormone therapy (HT; administration of HT within 365 days of diagnosis in eligible patients) at an urban safety net hospital. METHODS: This retrospective, observational study included women diagnosed with nonmetastatic, T1c or greater, estrogen and/or progesterone receptor-positive breast cancer from 2006 to 2008. Data sources included the hospital cancer registry and electronic medical record. Compliance with the NQF quality metric was defined as HT prescription within 365 days of diagnosis. Bivariate analysis compared compliant with noncompliant patients. Qualitative analysis assessed reasons for delayed compliance (HT at > 365 days) and never compliance (no HT at 4 years). RESULTS: Of 113 eligible patients, the majority were racial/ethnic minority (56%), stage II (54%), unmarried (60%), and had public or no insurance (72%). Sixty-four percent were compliant, and 36% were noncompliant. Of the noncompliant, 78% had delayed compliance, and 22% were never compliant. Noncompliant patients were significantly more likely to be Black, Hispanic, foreign-born, and stage III at diagnosis. Ten reasons for delayed compliance were identified, including patient- and system-level barriers. Most patients (56%) had more than one reason contributing to delay. CONCLUSION: Urgently needed interventions to reduce disparities in breast cancer treatment should take into account obstacles inherent among immigrant and indigent populations and complexities of multidisciplinary cancer care.

Boston Patient Navigation Research Program: the impact of navigation on time to diagnostic resolution after abnormal cancer screening.

BACKGROUND: There is a need for controlled studies to assess the impact of patient navigation in vulnerable cancer populations. METHODS: Boston Patient Navigation Research Program conducted a quasi-experimental patient navigation intervention across six federally qualified inner-city community health centers, three assigned to a breast cancer navigation intervention and three assigned to a cervical cancer navigation intervention; each group then served as the control for the other. Eligible women had an abnormal breast or cervical cancer screening test conducted at one of the participating health centers during a baseline (2004-2005) or intervention period (2007-2008). Kaplan-Meier survival curves and proportional hazards regression examined the effect of patient navigation on time to definitive diagnosis, adjusting for covariates, clustering by clinic and differences between the baseline and intervention period. RESULTS: We enrolled 997 subjects in the baseline period and 3,041 subjects during the intervention period, of whom 1,497 were in the navigated arm, and 1,544 in the control arm. There was a significant decrease in time to diagnosis for subjects in the navigated group compared with controls among those with a cervical screening abnormality [aHR 1.46; 95% confidence interval (CI), 1.1-1.9]; and among those with a breast cancer screening abnormality that resolved after 60 days (aHR 1.40; 95% CI, 1.1-1.9), with no differences before 60 days. CONCLUSIONS: This study documents a benefit of patient navigation on time to diagnosis among a racially/ethnically diverse inner city population. IMPACT: Patient navigation may address cancer health disparities by reducing time to diagnosis following an abnormal cancer-screening event.

Adherence to conservative management recommendations for abnormal pap test results in adolescents.

OBJECTIVE: To investigate whether the 2006 American Society for Colposcopy and Cervical Pathology guidelines for conservative management of minimally abnormal Pap test results (atypical squamous cells of undetermined significance, human papillomavirus-positive, and low-grade squamous intraepithelial lesions) and moderate dysplasia (cervical intraepithelial neoplasia 2) in adolescents 1) resulted in fewer colposcopies and loop electrosurgical excision procedures (LEEPs) in adolescents or 2) resulted in unintended treatment changes in older age groups. METHODS: We analyzed data from 1,806 women aged 18 years and older attending one of six community health centers who were diagnosed with abnormal Pap test results between January 1, 2004, and December 31, 2008. We used multivariable logistic regression to examine treatment differences in women with minimally abnormal Pap test results before and after guideline changes. Variables included date of abnormality, site of care, race or ethnicity, language, and insurance type. We used Fisher exact tests to examine rates of LEEP in patients with moderate dysplasia before and after guideline publication. RESULTS: Among 206 women aged 18-20 years, rates of colposcopy after a minimally abnormal Pap test result decreased from 78% (n=102) to 45% (n=34) after guideline changes (P<.001). Colposcopy among women over age 21 (n=1,542) remained unchanged (greater than 90%). Multivariable logistic regression indicated that both date of abnormality and site of care were associated with colposcopy referral. After guideline changes, management of moderate dysplasia with LEEP in women aged 18-23 decreased from 55% to 18% (P=.04); rates remained stable in women ages 24 and older (70% compared with 74%; P=.72). CONCLUSION: Health care providers quickly adopted new conservative management guidelines for low-income, minority adolescents, which may reduce preterm deliveries in these high-risk populations. LEVEL OF EVIDENCE: II.

Predictors of timely follow-up after abnormal cancer screening among women seeking care at urban community health centers.

BACKGROUND: We sought to measure time and identify predictors of timely follow-up among a cohort of racially/ethnically diverse inner city women with breast and cervical cancer screening abnormalities. METHODS: Eligible women had an abnormality detected on a mammogram or Papanicolaou (Pap) test between January 2004 and December 2005 in 1 of 6 community health centers in Boston, Massachusetts. Retrospective chart review allowed us to measure time to diagnostic resolution. We used Cox proportional hazards models to develop predictive models for timely resolution (defined as definitive diagnostic services completed within 180 days from index abnormality). RESULTS: Among 523 women with mammography abnormalities and 474 women with Pap test abnormalities, >90% achieved diagnostic resolution within 12 months. Median time to resolution was longer for Pap test than for mammography abnormalities (85 vs 27 days). Site of care, rather than any sociodemographic characteristic of individuals, including race/ethnicity, was the only significant predictor of timely follow-up for both mammogram and Pap test abnormalities. CONCLUSIONS: Site-specific community-based interventions may be the most effective interventions to reduce cancer health disparities when addressing the needs of underserved populations.
