Effect of a multimodal reminder program on repeat mammogram screening

Behavioral Interventions to Improve Breast Cancer Screening Outreach: Two Randomized Clinical Trials

Importance

Despite public health efforts, breast cancer screening rates remain below national goals.

Objective

To evaluate whether bulk ordering, text messaging, and clinician endorsement increase breast cancer screening rates.

Design, Setting, and Participants

Two concurrent, pragmatic, randomized clinical trials, each with a 2-by-2 factorial design, were conducted between October 25, 2021, and April 25, 2022, in 2 primary care regions of an academic health system. The trials included women aged 40 to 74 years with at least 1 primary care visit in the past 2 years who were eligible for breast cancer screening.

Interventions

Patients in trial A were randomized in a 1:1 ratio to receive a signed bulk order for mammogram or no order; in a factorial design, patients were concurrently randomized in a 1:1 ratio to receive or not receive text message reminders. Patients in trial B were randomized in a 1:1 ratio to receive a message signed by their primary care clinician (clinician endorsement) or from the organization (standard messaging); in a factorial design, patients were concurrently randomized in a 1:1 ratio to receive or not receive text message reminders.

Main Outcomes and Measures

The primary outcome was the proportion of patients who completed a screening mammogram within 3 months.

Results

Among 24 632 patients included, the mean (SD) age was 60.4 (7.5) years. In trial A, at 3 months, 15.4% (95% CI, 14.6%-16.1%) of patients in the bulk order arm and 12.7% (95% CI, 12.1%-13.4%) in the no order arm completed a mammogram, showing a significant increase (absolute difference, 2.7%; 95% CI, 1.6%-3.6%; P < .001). In the text messaging comparison arms, 15.1% (95% CI, 14.3%-15.8%) of patients receiving a text message completed a mammogram compared with 13.0% (95% CI, 12.4%-13.7%) of those in the no text messaging arm, a significant increase (absolute difference of 2.1%; 95% CI, 1.0%-3.0%; P < .001). In trial B, at 3 months, 12.5% (95% CI, 11.3%-13.7%) of patients in the clinician endorsement arm completed a mammogram compared with 11.4% (95% CI, 10.3%-12.5%) of those in the standard messaging arm, which was not significant (absolute difference, 1.1%; 95% CI, -0.5% to 2.7%; P = .18). In the text messaging comparison arms, 13.2% (95% CI, 12.0%-14.4%) of patients receiving a text message completed a mammogram compared with 10.7% (95% CI, 9.7%-11.8%) of those in the no text messaging arm, a significant increase (absolute difference, 2.5%; 95% CI, 0.8%-4.0%; P = .003).

Conclusions and Relevance

These findings show that text messaging women after initial breast cancer screening outreach via either electronic portal or mailings, as well as bulk ordering with or without text messaging, can increase mammogram completion rates.

The Breast-Imaging Operations, Practices and Systems Inventory: A framework to examine mammography facility effects on screening in rural communities

PURPOSE

Develop and test a measurement framework of mammogram facility resources, policies, and practices in Appalachia.

METHODS

Survey items describing 7 domains of imaging facility qualities were developed and tested in the Appalachian regions of Kentucky, Ohio, Pennsylvania, Virginia, and West Virginia. Medicare claims data (2016-2018) were obtained on catchment area mammogram services. Construct validity was examined from associations with facility affiliation, community characteristics, mammogram screening uptake, and market reach. Analyses were performed with t-tests and ANOVA.

RESULTS

A total of 192 (of 377) sites completed the survey. Five factors were initially selected in exploratory factor analysis (FA) and refined in confirmatory FA: capacity, outreach & marketing, operational support, radiology review (NNFI = .94, GFI = 0.93), and diagnostic services (NNFI = 1.00, GFI = 0.99). Imaging capacity and diagnostic services were associated with screening uptake, with capacity strongly associated with catchment area demographic and economic characteristics. Imaging facilities in economically affluent versus poorer areas belong to larger health systems and have significantly more resources (P < .001). Facilities in economically distressed locations in Appalachia rely more heavily on outreach activities (P < .001). Higher facility capacity was significantly associated (P < .05) with larger catchment area size (median split: 48.5 vs 51.6), mammogram market share (47.4 vs 52.7), and screening uptake (47.6 vs 52.4).

CONCLUSIONS

A set of 18 items assessing breast imaging services and facility characteristics was obtained, representing policies and practices related to a facility's catchment area size, market share, and mammogram screening uptake.

Association of Electronic Self-Scheduling and Screening Mammogram Completion

INTRODUCTION

The purpose of this study was to evaluate if an electronic health record (EHR) self-scheduling function was associated with changes in mammogram completion for primary care patients who were eligible for a screening mammogram using U.S. Preventive Service Task Force recommendations.

METHODS

This was a retrospective cohort study (September 1, 2014-August 31, 2019, analyses completed in 2022) using a difference-in-differences design to examine mammogram completion before versus after the implementation of self-scheduling. The difference-in-differences estimate was the interaction between time (pre-versus post-implementation) and group (active EHR patient portal versus inactive EHR patient portal). The primary outcome was mammogram completion among all eligible patients, with completion defined as receiving a mammogram within 6 months post-visit. The secondary outcome was mammogram completion among patients who received a clinician order during their visit.

RESULTS

The primary analysis included 35,257 patient visits. The overall mammogram completion rate in the pre-period was 22.2% and 49.7% in the post-period. EHR self-scheduling was significantly associated with increased mammogram completion among those with an active EHR portal, relative to patients with an inactive portal (adjusted difference 13.2 percentage points [95% CI 10.6-15.8]). For patients who received a clinician mammogram order at their eligible visit, self-scheduling was significantly associated with increased mammogram completion among patients with an active EHR portal account (adjusted difference 14.7 percentage points, [95% CI 10.9-18.5]).

CONCLUSIONS

EHR-based self-scheduling was associated with a significant increase in mammogram completion among primary care patients. Self-scheduling can be a low-cost, scalable function for increasing preventive cancer screenings.

Multilevel Predictors of Continued Adherence to Breast Cancer Screening Among Women Ages 50-74 Years in a Screening Population

Background: U.S. women of ages 50-74 years are recommended to receive screening mammography at least biennially. Our objective was to evaluate multilevel predictors of nonadherence among screened women, as these are not well known. Materials and Methods: A cohort study was conducted among women of ages 50-74 years with a screening mammogram in 2011 with a negative finding (Breast Imaging-Reporting and Data System 1 or 2) within Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium research centers. We evaluated the association between woman-level factors, radiology facility, and PROSPR research center, and nonadherence to breast cancer screening guidelines, defined as not receiving breast imaging within 27 months of an index screening mammogram. Multilevel mixed-effects logistic regression was used to calculate odds ratios and 95% confidence intervals. Results: Nonadherence to guideline-recommended screening interval was 15.5% among 51,241 women with a screening mammogram. Non-Hispanic Asian/Pacific Islander women, women of other races, heavier women, and women of ages 50-59 years had a greater odds of nonadherence. There was no association with ZIP code median income. Nonadherence varied by research center and radiology facility (variance = 0.10, standard error = 0.03). Adjusted radiology facility nonadherence rates ranged from 10.0% to 26.5%. One research center evaluated radiology facility communication practices for screening reminders and scheduling, but these were not associated with nonadherence. Conclusions: Breast cancer screening interval nonadherence rates in screened women varied across radiology facilities even after adjustment for woman-level characteristics and research center. Future studies should investigate other characteristics of facilities, practices, and health systems to determine factors integral to increasing continued adherence to breast cancer screening.

Automated telephone communication systems for preventive healthcare and management of long-term conditions

BACKGROUND

Automated telephone communication systems (ATCS) can deliver voice messages and collect health-related information from patients using either their telephone's touch-tone keypad or voice recognition software. ATCS can supplement or replace telephone contact between health professionals and patients. There are four different types of ATCS: unidirectional (one-way, non-interactive voice communication), interactive voice response (IVR) systems, ATCS with additional functions such as access to an expert to request advice (ATCS Plus) and multimodal ATCS, where the calls are delivered as part of a multicomponent intervention.

OBJECTIVES

To assess the effects of ATCS for preventing disease and managing long-term conditions on behavioural change, clinical, process, cognitive, patient-centred and adverse outcomes.

SEARCH METHODS

We searched 10 electronic databases (the Cochrane Central Register of Controlled Trials; MEDLINE; Embase; PsycINFO; CINAHL; Global Health; WHOLIS; LILACS; Web of Science; and ASSIA); three grey literature sources (Dissertation Abstracts, Index to Theses, Australasian Digital Theses); and two trial registries (www.controlled-trials.com; www.clinicaltrials.gov) for papers published between 1980 and June 2015.

SELECTION CRITERIA

Randomised, cluster- and quasi-randomised trials, interrupted time series and controlled before-and-after studies comparing ATCS interventions, with any control or another ATCS type were eligible for inclusion. Studies in all settings, for all consumers/carers, in any preventive healthcare or long term condition management role were eligible.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods to select and extract data and to appraise eligible studies.

MAIN RESULTS

We included 132 trials (N = 4,669,689). Studies spanned across several clinical areas, assessing many comparisons based on evaluation of different ATCS types and variable comparison groups. Forty-one studies evaluated ATCS for delivering preventive healthcare, 84 for managing long-term conditions, and seven studies for appointment reminders. We downgraded our certainty in the evidence primarily because of the risk of bias for many outcomes. We judged the risk of bias arising from allocation processes to be low for just over half the studies and unclear for the remainder. We considered most studies to be at unclear risk of performance or detection bias due to blinding, while only 16% of studies were at low risk. We generally judged the risk of bias due to missing data and selective outcome reporting to be unclear.For preventive healthcare, ATCS (ATCS Plus, IVR, unidirectional) probably increase immunisation uptake in children (risk ratio (RR) 1.25, 95% confidence interval (CI) 1.18 to 1.32; 5 studies, N = 10,454; moderate certainty) and to a lesser extent in adolescents (RR 1.06, 95% CI 1.02 to 1.11; 2 studies, N = 5725; moderate certainty). The effects of ATCS in adults are unclear (RR 2.18, 95% CI 0.53 to 9.02; 2 studies, N = 1743; very low certainty).For screening, multimodal ATCS increase uptake of screening for breast cancer (RR 2.17, 95% CI 1.55 to 3.04; 2 studies, N = 462; high certainty) and colorectal cancer (CRC) (RR 2.19, 95% CI 1.88 to 2.55; 3 studies, N = 1013; high certainty) versus usual care. It may also increase osteoporosis screening. ATCS Plus interventions probably slightly increase cervical cancer screening (moderate certainty), but effects on osteoporosis screening are uncertain. IVR systems probably increase CRC screening at 6 months (RR 1.36, 95% CI 1.25 to 1.48; 2 studies, N = 16,915; moderate certainty) but not at 9 to 12 months, with probably little or no effect of IVR (RR 1.05, 95% CI 0.99, 1.11; 2 studies, 2599 participants; moderate certainty) or unidirectional ATCS on breast cancer screening.Appointment reminders delivered through IVR or unidirectional ATCS may improve attendance rates compared with no calls (low certainty). For long-term management, medication or laboratory test adherence provided the most general evidence across conditions (25 studies, data not combined). Multimodal ATCS versus usual care showed conflicting effects (positive and uncertain) on medication adherence. ATCS Plus probably slightly (versus control; moderate certainty) or probably (versus usual care; moderate certainty) improves medication adherence but may have little effect on adherence to tests (versus control). IVR probably slightly improves medication adherence versus control (moderate certainty). Compared with usual care, IVR probably improves test adherence and slightly increases medication adherence up to six months but has little or no effect at longer time points (moderate certainty). Unidirectional ATCS, compared with control, may have little effect or slightly improve medication adherence (low certainty). The evidence suggested little or no consistent effect of any ATCS type on clinical outcomes (blood pressure control, blood lipids, asthma control, therapeutic coverage) related to adherence, but only a small number of studies contributed clinical outcome data.The above results focus on areas with the most general findings across conditions. In condition-specific areas, the effects of ATCS varied, including by the type of ATCS intervention in use.Multimodal ATCS probably decrease both cancer pain and chronic pain as well as depression (moderate certainty), but other ATCS types were less effective. Depending on the type of intervention, ATCS may have small effects on outcomes for physical activity, weight management, alcohol consumption, and diabetes mellitus. ATCS have little or no effect on outcomes related to heart failure, hypertension, mental health or smoking cessation, and there is insufficient evidence to determine their effects for preventing alcohol/substance misuse or managing illicit drug addiction, asthma, chronic obstructive pulmonary disease, HIV/AIDS, hypercholesterolaemia, obstructive sleep apnoea, spinal cord dysfunction or psychological stress in carers.Only four trials (3%) reported adverse events, and it was unclear whether these were related to the interventions.

AUTHORS' CONCLUSIONS

ATCS interventions can change patients' health behaviours, improve clinical outcomes and increase healthcare uptake with positive effects in several important areas including immunisation, screening, appointment attendance, and adherence to medications or tests. The decision to integrate ATCS interventions in routine healthcare delivery should reflect variations in the certainty of the evidence available and the size of effects across different conditions, together with the varied nature of ATCS interventions assessed. Future research should investigate both the content of ATCS interventions and the mode of delivery; users' experiences, particularly with regard to acceptability; and clarify which ATCS types are most effective and cost-effective.

Breast cancer screening utilization and understanding of current guidelines among rural U.S. women with private insurance

Women living in rural areas of the U.S. face disparities in screening mammography and breast cancer outcomes. We sought to evaluate utilization of mammography, awareness of screening guidelines, and attitudes towards screening among rural insured U.S. women. We conducted a cross-sectional self-administered anonymous survey among 2000 women aged 40-64 insured by the National Rural Electric Cooperative Association, a non-profit insurer for electrical utility workers in predominantly rural areas across the U.S. Outcomes included mammographic screening in the past year, screening interval, awareness of guidelines, and perceived barriers to screening. 1588 women responded to the survey (response rate 79.4 %). 74 % of respondents lived in a rural area. Among women aged 40-49, 66.5 % reported mammographic screening in the past year. 46 % received annual screening, 32 % biennial screening, and 22 % rare/no screening. Among women aged 50-64, 77.1 % reported screening in the past year. 63 % received annual screening, 25 % biennial screening, and 12 % rare/no screening. The majority of women (98 %) believed that the mammography can find breast cancer early and save lives. Less than 1 % of younger women, and only 14 % of women over age 50 identified the recommendations of the U.S. Preventative Services Screening Task Force as the current expert recommendations for screening. Screening practices tended to follow perceived guideline recommendations. When rural U.S. women over age 40 have insurance, most receive breast cancer screening. The screening guidelines of cancer advocacy groups and specialty societies appear more influential and widely recognized than those of the U.S. preventative services taskforce.

Sustaining mammography screening among the medically underserved: a follow-up evaluation

BACKGROUND

Our previous three-arm comparative effectiveness intervention in community clinic patients who were not up-to-date with screening resulted in mammography rates over 50% in all arms.

OBJECTIVE

Our aim was to evaluate the effectiveness and cost-effectiveness of the three interventions on improving biennial screening rates among eligible patients.

METHODS

A three-arm quasi-experimental evaluation was conducted in eight community clinics from 2008 to 2011. Screening efforts included (1) enhanced care: Participants received an in-person recommendation from a research assistant (RA) in year 1, and clinics followed usual clinic protocol for scheduling screening mammograms; (2) education intervention: Participants received education and in-person recommendation from an RA in year 1, and clinics followed usual clinic protocol for scheduling mammograms; or (3) nurse support: A nurse manager provided in-person education and recommendation, scheduled mammograms, and followed up with phone support. In all arms, mammography was offered at no cost to uninsured patients.

RESULTS

Of 624 eligible women, biennial mammography within 24-30 months of their previous test was performed for 11.0% of women in the enhanced-care arm, 7.1% in the education- intervention arm, and 48.0% in the nurse-support arm (p<0.0001). The incremental cost was $1,232 per additional woman undergoing screening with nurse support vs. enhanced care and $1,092 with nurse support vs. education.

CONCLUSIONS

Biennial mammography screening rates were improved by providing nurse support but not with enhanced care or education. However, this approach was not cost-effective.

Formative Evaluation to Assess Communication Technology Access and Health Communication Preferences of Alaska Native People

OBJECTIVE

Information technology can improve the quality, safety, and efficiency of healthcare delivery by improving provider and patient access to health information. We conducted a nonrandomized, cross-sectional, self-report survey to determine whether Alaska Native and American Indian (AN/AI) people have access to the health communication technologies available through a patient-centered medical home.

METHODS

In 2011, we administered a self-report survey in an urban, tribally owned and operated primary care center serving AN/AI adults. Patients in the center's waiting rooms completed the survey on paper; center staff completed it electronically.

RESULTS

Approximately 98% (n = 654) of respondents reported computer access, 97% (n = 650) email access, and 94% (n = 631) mobile phone use. Among mobile phone users, 60% had Internet access through their phones. Rates of computer access (p = .011) and email use (p = .005) were higher among women than men, but we found no significant gender difference in mobile phone access to the Internet or text messaging. Respondents in the oldest age category (65-80 years of age) were significantly less likely to anticipate using the Internet to schedule appointments, refill medications, or communicate with their health care providers (all p < .001).

CONCLUSION

Information on use of health communication technologies enables administrators to deploy these technologies more efficiently to address health concerns in AN/AI communities. Our results will drive future research on health communication for chronic disease screening and health management.

An experience of qualified preventive screening: shiraz smart screening software

BACKGROUND

Computerized preventive screening software is a cost effective intervention tool to address non-communicable chronic diseases. Shiraz Smart Screening Software (SSSS) was developed as an innovative tool for qualified screening. It allows simultaneous smart screening of several high-burden chronic diseases and supports reminder notification functionality. The extent in which SSSS affects screening quality is also described.

METHODS

Following software development, preventive screening and annual health examinations of 261 school staff (Medical School of Shiraz, Iran) was carried out in a software-assisted manner. To evaluate the quality of the software-assisted screening, we used quasi-experimental study design and determined coverage, irregular attendance and inappropriateness proportions in relation with the manual and software-assisted screening as well as the corresponding number of requested tests.

RESULTS

In manual screening method, 27% of employees were covered (with 94% irregular attendance) while by software-assisted screening, the coverage proportion was 79% (attendance status will clear after the specified time). The frequency of inappropriate screening test requests, before the software implementation, was 41.37% for fasting plasma glucose, 41.37% for lipid profile, 0.84% for occult blood, 0.19% for flexible sigmoidoscopy/colonoscopy, 35.29% for Pap smear, 19.20% for mammography and 11.2% for prostate specific antigen. All of the above were corrected by the software application. In total, 366 manual screening and 334 software-assisted screening tests were requested.

CONCLUSION

SSSS is an innovative tool to improve the quality of preventive screening plans in terms of increased screening coverage, reduction in inappropriateness and the total number of requested tests.

Designing audience-centered interactive voice response messages to promote cancer screenings among low-income Latinas

INTRODUCTION

Cancer screening rates among Latinas are suboptimal. The objective of this study was to explore how Latinas perceive cancer screening and the use and design of interactive voice response (IVR) messages to prompt scheduling of 1 or more needed screenings.

METHODS

Seven focus groups were conducted with Latina community health center patients (n = 40) in need of 1 or more cancer screenings: 5 groups were of women in need of 1 cancer screening (breast, cervical, or colorectal), and 2 groups were of women in need of multiple screenings. A bilingual researcher conducted all focus groups in Spanish using a semistructured guide. Focus groups were recorded, transcribed, and translated into English for analysis. Emergent themes were identified by using thematic content analysis.

RESULTS

Participants were familiar with cancer screening and viewed it positively, although barriers to screening were identified (unaware overdue for screening, lack of physician referral, lack of insurance or insufficient insurance coverage, embarrassment or fear of screening procedures, fear of screening outcomes). Women needing multiple screenings voiced more concern about screening procedures, whereas women in need of a single screening expressed greater worry about the screening outcome. Participants were receptive to receiving IVR messages and believed that culturally appropriate messages that specified needed screenings while emphasizing the benefit of preventive screening would motivate them to schedule needed screenings.

CONCLUSION

Participants' receptiveness to IVR messages suggests that these messages may be an acceptable strategy to promote cancer screening among underserved Latina patients. Additional research is needed to determine the effectiveness of IVR messages in promoting completion of cancer screening.

Get screened: a randomized trial of the incremental benefits of reminders, recall, and outreach on cancer screening

BACKGROUND

Rates of breast cancer (BC) and colorectal cancer (CRC) screening are particularly low among poor and minority patients. Multifaceted interventions have been shown to improve cancer-screening rates, yet the relative impact of the specific components of these interventions has not been assessed. Identifying the specific components necessary to improve cancer-screening rates is critical to tailor interventions in resource limited environments.

OBJECTIVE

To assess the relative impact of various components of the reminder, recall, and outreach (RRO) model on BC and CRC screening rates within a safety net practice.

DESIGN

Pragmatic randomized trial.

PARTICIPANTS

Men and women aged 50-74 years past due for CRC screen and women aged 40-74 years past due for BC screening.

INTERVENTIONS

We randomized 1,008 patients to one of four groups: (1) reminder letter; (2) letter and automated telephone message (Letter + Autodial); (3) letter, automated telephone message, and point of service prompt (Letter + Autodial + Prompt); or (4) letter and personal telephone call (Letter + Personal Call).

MAIN MEASURES

Documentation of mammography or colorectal cancer screening at 52 weeks following randomization.

KEY RESULTS

Compared to a reminder letter alone, Letter + Personal Call was more effective at improving screening rates for BC (17.8 % vs. 27.5 %; AOR 2.2, 95 % CI 1.2-4.0) and CRC screening (12.2 % vs. 21.5 %; AOR 2.0, 95 % CI 1.1-3.9). Compared to letter alone, a Letter + Autodial + Prompt was also more effective at improving rates of BC screening (17.8 % vs. 28.2 %; AOR 2.1, 95 % CI 1.1-3.7) and CRC screening (12.2 % vs. 19.6 %; AOR 1.9, 95 % CI 1.0-3.7). Letter + Autodial was not more effective than a letter alone at improving screening rates.

CONCLUSIONS

The addition of a personal telephone call or a patient-specific provider prompt were both more effective at improving mammogram and CRC screening rates compared to a reminder letter alone. The use of automated telephone calls, however, did not provide any incremental benefit to a reminder letter alone.

Breast cancer screening in an insured population: whom are we missing?

INTRODUCTION

Kaiser Permanente Colorado is an integrated health care system that uses automatic reminder programs and reduces barriers to access preventive services, including financial barriers. Breast cancer screening rates have not improved during the last five years, and rates differ between subgroups: for example, black and Latina women have lower rates of mammography screening than other racial groups.

METHODS

We retrospectively evaluated data from 47,946 women age 52 to 69 years who had continuous membership for 24 months but had not undergone mammography. Poisson regression models estimated relative risk for the impact of self-identified race/ethnicity, socioeconomic characteristics, health status, and use of health care services on screening completion.

RESULTS

The distribution of race/ethnicity among unscreened women was 55.5% white, 7.0% Latina, and 3.7% black, but race/ethnicity data were missing for 29%. Of these, no record of race/ethnicity was available for 86.7%, and for 5.1%, the data request was recorded but the women declined to identify their race/ethnicity. Nonwhite ethnicity increased risk of screening failure if black, Latina, "other" (eg, American Indian), or missing race/ethnicity. Population-attributable risks were low for minorities compared with the group for whom race/ethnicity data was missing. A greater number of office visits in any setting was associated with greater likelihood of undergoing mammography. Women with missing race/ethnicity data had fewer visits and were less likely to have an identified primary care physician.

CONCLUSIONS

Greater improvement in mammography screening rates could be achieved in our population by increasing screening among women with missing race/ethnicity data, rather than by targeting those who are known to be of racial/ethnic minorities. Efforts to address screening disparities have been refocused on inreach and outreach to our "missing women."

Strategies associated with higher postpartum glucose tolerance screening rates for gestational diabetes mellitus patients

BACKGROUND

Most women with histories of gestational diabetes mellitus do not receive a postpartum screening test for type 2 diabetes, even though they are at increased risk. The objective of this study was to identify factors associated with high rates of postpartum glucose screening.

METHODS

This cross-sectional analysis assessed characteristics associated with postpartum diabetes screening for patients with gestational diabetes mellitus (GDM)-affected pregnancies self-reported by randomly sampled licensed obstetricians/gynecologists (OBs/GYNs) in Ohio in 2010.

RESULTS

Responses were received from 306 OBs/GYNs (56.5% response rate), among whom 69.9% reported frequently (always/most of the time) screening women with GDM-affected pregnancies for abnormal glucose tolerance at the postpartum visit. Compared to infrequent screeners, OBs/GYNs who frequently screen for postpartum glucose tolerance were statistically (p<0.05) more likely to have a clinical protocol addressing postpartum testing (67.2% vs. 26.7%), an electronic reminder system for providers (10.8% vs. 2.2%) and provide reminders to patients (16.4% vs. 4.4%). Frequent screeners were more likely to use recommended fasting blood glucose or 2-hour oral glucose tolerance test (61.8% vs. 34.6%, p<0.001) than infrequent screeners.

CONCLUSIONS

Strategies associated with higher postpartum glucose screening for GDM patients included clinical protocols for postpartum testing, electronic medical records to alert providers of the need for testing, and reminders to patients.

Gestational diabetes mellitus and postpartum care practices of nurse-midwives

INTRODUCTION

Postpartum screening for glucose intolerance among women with recent histories of gestational diabetes mellitus (GDM) is important for identifying women with continued glucose intolerance after birth, yet screening rates are suboptimal. In a thorough review of the literature, we found no studies of screening practices among certified nurse-midwives (CNMs). The objectives of our study were to estimate the prevalence of postpartum screening for abnormal glucose tolerance and related care by CNMs for women with recent histories of GDM and to identify strategies for improvement.

METHODS

From October through December 2010, the Ohio Department of Health sent a survey by mail and Internet to all licensed CNMs practicing in Ohio. We calculated prevalence estimates for knowledge, attitudes, clinical practices, and behaviors related to postpartum diabetes screening. Chi-square statistics were used to assess differences in self-reported clinical behaviors by frequency of postpartum screening.

RESULTS

Of the 146 CNMs who provided postpartum care and responded to the survey (62.2% response rate), 50.4% reported screening women with GDM-affected pregnancies for abnormal glucose tolerance at the postpartum visit. Of CNMs who screened postpartum, only 48.4% used fasting blood sugar or the 2-hour oral glucose tolerance test. Although 86.2% of all responding CNMs reported that they inform women with recent histories of GDM of their increased risk for type 2 diabetes mellitus, only 63.1% counseled these women to exercise regularly and 23.3% reported referring overweight/obese women to a diet support group or other nutrition counseling. CNMs reported that identification of community resources for lifestyle interventions and additional training in postpartum screening guidelines may help to improve postpartum care.

DISCUSSION

CNMs in Ohio reported suboptimal levels of postpartum diabetes testing and use of a recommended postpartum test. Providing CNMs with additional training and identifying community resources to support needed lifestyle behavior change may improve care for women with recent GDM-affected pregnancies.

State-of-the-art and future directions in multilevel interventions across the cancer control continuum

We conducted literature searches and analyses to describe the current state of multilevel intervention (MLI) research and to identify opportunities to advance cancer control and prevention. We found single-level studies that considered other contextually important levels, and multilevel health-care systems research and community-wide studies. This literature is characterized by limited reporting of theoretical, contextual, temporal, and implementation factors. Most MLIs focus on prevention and screening, rather than diagnosis, treatment, or survivorship. Opportunities relate to 1) dynamic, adaptive emergent interventions and research designs that evolve over time by attending to contextual factors and interactions across levels; 2) analyses that include simulation modeling, or multimethod approaches that integrate quantitative and qualitative methods; and 3) translation and intervention approaches that locally reinvent MLIs in different contexts. MLIs have great potential to reduce cancer burden by using theory and integrating quantitative, qualitative, participatory, and transdisciplinary methods that continually seek alignment across intervention levels, pay attention to context, and adapt over time.

Hepatocellular carcinoma screening rates vary by etiology of cirrhosis and involvement of gastrointestinal sub-specialists

BACKGROUND

Regular screening of cirrhotic patients for hepatocellular carcinoma (HCC) has been suboptimal, but there is little data regarding specific risk factors for reduced screening.

METHODS

From 1996 to 2010, patients with cirrhosis were retrospectively identified from outpatient gastroenterology and primary care practices. Data was obtained from the diagnosis of cirrhosis until the time of elevated alpha-fetoprotein (AFP) or lesion suspicious for HCC, death, liver transplantation, or end of the data collection period. Recommended screening was defined as abdominal imaging (ultrasound, contrast-enhanced CT, or MRI) with or without serum alpha-fetoprotein (AFP) at least once every 12 months based on professional guidelines.

RESULTS

One hundred fifty-six patients with cirrhosis were identified. The etiologies of cirrhosis were viral hepatitis (n = 65), alcohol (n = 40), non-alcoholic steatohepatitis (NASH) (n = 27), and non-viral, non-alcoholic, non-NASH cirrhosis (n = 24). Of the 156 patients, 51% received recommended screening for HCC. Patients with NASH cirrhosis received recommended screening significantly less (p = 0.016) than cirrhotics with viral hepatitis, alcoholic cirrhosis, or non-viral, non-alcoholic, non-NASH cirrhosis and were less likely to receive gastroenterology referral (p < 0.001). Additionally, 20 patients were diagnosed with cirrhosis incidentally during a surgical procedure. These patients were significantly less likely to receive recommended HCC screening than those diagnosed non-surgically (10.0 vs. 56.6%; p < 0.001). Screening was significantly more likely to occur in patients seen regularly by a gastrointestinal subspecialist (66.7 vs. 22.8%; p < 0.001).

CONCLUSIONS

Patients with NASH cirrhosis and incidentally discovered cirrhosis have low rates of HCC screening and are referred less often to gastroenterologists. These data suggest a need for increased education about NASH cirrhosis and better systems of communication among general practitioners, surgeons, and gastroenterologists.

Promoting cancer screening within the patient centered medical home

While consensus has grown that primary care is the essential access point in a high-performing health care system, the current model of primary care underperforms in both chronic disease management and prevention. The Patient Centered Medical Home model (PCMH) is at the center of efforts to reinvent primary care practice, and is regarded as the most promising approach to addressing the burden of chronic disease, improving health outcomes, and reducing health spending. However, the potential for the medical home to improve the delivery of cancer screening (and preventive services in general) has received limited attention in both conceptualization and practice. Medical home demonstrations to date have included few evidence-based preventive services in their outcome measures, and few have evaluated the effect of different payment models. Decreasing use of hospitals and emergency rooms and an emphasis on improving chronic care represent improvements in effective delivery of healthcare, but leave opportunities for reducing the burden of cancer untouched. Data confirm that what does or does not happen in the primary care setting has a substantial impact on cancer outcomes. Insofar as cancer is the leading cause of death before age 80, the PCMH model must prioritize adherence to cancer screening according to recommended guidelines, and systems, financial incentives, and reimbursements must be aligned to achieve that goal. This article explores capacities that are needed in the medical home model to facilitate the integration of cancer screening and other preventive services. These capacities include improved patient access and communication, health risk assessments, periodic preventive health exams, use of registries that store cancer risk information and screening history, ability to track and follow up on tests and referrals, feedback on performance, and payment models that reward cancer screening.

Telephone counseling and attendance in a national mammography-screening program a randomized controlled trial

BACKGROUND

In Germany, a mammography-screening program (MSP) was implemented on a national level. It complies with all criteria of the European guidelines for quality assurance in screening mammography; however, the attendance rate is 54%, falling short of the target attendance rate of 70%. The aim of this study was to investigate whether additional telephone counseling improves attendance among nonresponders and the level of satisfaction with telephone counseling.

DESIGN

In a prospective RCT, women identified as nonresponders in the MSP were randomized to a control group that received written reminders or to an intervention group that additionally received telephone counseling. In a follow-up, a subset of the intervention group was contacted by telephone regarding their satisfaction with telephone counseling.

SETTING/PARTICIPANTS

In 2008, a total of 5477 women aged 50-69 years who were eligible for the German MSP but had not participated up to 6 weeks after the first invitation were included in the study.

INTERVENTIONS

Individual telephone counseling consisted of scripted calls from a trained counselor who provided information on MSP and answered the woman's questions.

MAIN OUTCOME MEASURES

Report of mammography use provided by the screening unit 3 months after the reminder was sent.

RESULTS

Analysis was conducted in 2009. Comparison of screening attendance revealed a significantly higher attendance rate in the intervention group compared with controls (29.7% vs 26.1%, p=0.0035). When only women for whom telephone numbers were available were analyzed, attendance was even better (35.5% vs 29.7%, p=0.0004). In the follow-up, 278 of 404 women were actually surveyed. Of those, 33% stated that telephone counseling had influenced their decision, 56% stated that they had undergone screening mammography, and 77% agreed that personal telephone counseling should be used routinely to encourage nonresponders to go for screening.

CONCLUSIONS

Individual telephone counseling for nonresponders to a national program for breast cancer screening was well accepted by participants and effective.

Eliminating disparities in cancer screening and follow-up of abnormal results: what will it take?

Health and health care disparities related to cancer are a major public health problem in the United States. Providing care that is truly patient-centered could address disparities in cancer screening and follow-up through better alignment between patient needs and health care resources available to address those needs. Key health care reforms offer promise for doing so.

Patient Barriers to Mammography Identified During a Reminder Program

Background: Patient mammogram reminders are effective at increasing screening, but patient barriers remain. We evaluated patient characteristics and reported barriers for their association with mammogram completion after a reminder program. Methods: This retrospective cohort study used data from electronic records and a subgroup survey. Participants were female Kaiser Permanente Northwest health maintenance organization (HMO) members aged 50-69 who were 20 months past their last mammogram (index date) and had received a reminder intervention (n = 4708). A mailed survey was completed by 340 of 667 (50.2%) women who received it. The intervention was a "mammogram due soon" postcard 20 months after the last mammogram, followed by up to two automated phone calls and one live call for nonresponders. The outcome was mammogram completion at 10 months after index date. Results: Characteristics associated with lower mammogram completion rates were aged <60 (odds ratio [OR] 0.69, p < 0.0001), health plan membership <5 years (OR 0.81, p = 0.019), family income <$40,000/year (OR 0.77, p = 0.018), and obesity (OR 0.67, p < 0.0001). Obese women were more likely than nonobese women to report "too much pain" from mammograms (31.3% vs.18.8%, p < 0.01). Younger women were more likely to endorse that they were "too busy" (19.1% vs. 6.4%, p < 0.001) and had more worries about mammogram accuracy (2.5 vs. 2.3 on a 5-point scale, p < 0.05). Pain mediated the relationship between obesity and mammogram completion rates (indirect effect = -0.111, p = 0.008). Conclusions: Important barriers to mammogram completion remain even after an effective mammogram reminder system among insured patients. Tailored interventions are necessary to overcome these barriers.

Get screened: a pragmatic randomized controlled trial to increase mammography and colorectal cancer screening in a large, safety net practice

Background

Most randomized controlled trials of interventions designed to promote cancer screening, particularly those targeting poor and minority patients, enroll selected patients. Relatively little is known about the benefits of these interventions among unselected patients.

Methods/Design

"Get Screened" is an American Cancer Society-sponsored randomized controlled trial designed to promote mammography and colorectal cancer screening in a primary care practice serving low-income patients. Eligible patients who are past due for mammography or colorectal cancer screening are entered into a tracking registry and randomly assigned to early or delayed intervention. This 6-month intervention is multimodal, involving patient prompts, clinician prompts, and outreach. At the time of the patient visit, eligible patients receive a low-literacy patient education tool. At the same time, clinicians receive a prompt to remind them to order the test and, when appropriate, a tool designed to simplify colorectal cancer screening decision-making. Patient outreach consists of personalized letters, automated telephone reminders, assistance with scheduling, and linkage of uninsured patients to the local National Breast and Cervical Cancer Early Detection program. Interventions are repeated for patients who fail to respond to early interventions. We will compare rates of screening between randomized groups, as well as planned secondary analyses of minority patients and uninsured patients. Data from the pilot phase show that this multimodal intervention triples rates of cancer screening (adjusted odds ratio 3.63; 95% CI 2.35 - 5.61).

Discussion

This study protocol is designed to assess a multimodal approach to promotion of breast and colorectal cancer screening among underserved patients. We hypothesize that a multimodal approach will significantly improve cancer screening rates.

Automated telephone calls improved completion of fecal occult blood testing

BACKGROUND

Although colorectal cancer (CRC) prognosis is improved by early diagnosis, screening rates remain low.

OBJECTIVE

To determine the effect of an automated telephone intervention on completion of fecal occult blood testing (FOBT).

RESEARCH DESIGN

In this randomized controlled trial conducted at Kaiser Permanente Northwest, a not-for-profit health maintenance organization, 5905 eligible patients aged 51 to 80, at average risk for CRC and due for CRC screening, were randomly assigned to an automated telephone intervention (n = 2943) or usual care (UC; n = 2962). The intervention group received up to three 1-minute automated telephone calls that provided a description and health benefits of FOBT. During the call, patients could request that an FOBT kit be mailed to their home. Those who requested but did not return the cards received an automated reminder call. Cox proportional hazard method was used to determine the independent effect of automated telephone calls on completion of an FOBT, after adjusting for age, sex, and prior CRC screening.

RESULTS

By 6 months after call initiation, 22.5% in the intervention and 16.0% in UC had completed an FOBT. Those in the intervention group were significantly more likely to complete an FOBT (hazard ratio, 1.31; 95% confidence interval, 1.10-1.56) compared with UC. Older patients (aged 71-80 vs. aged 51-60) were also more likely to complete FOBT (hazard ratio, 1.48; 95% confidence interval, 1.07-2.04).

CONCLUSIONS

Automated telephone calls increased completion of FOBT. Further research is needed to evaluate automated telephone interventions among diverse populations and in other clinical settings.
