Interventions for patients, providers, and health care organizations

Uptake of colorectal cancer screening: system, provider and individual factors and strategies to improve participation

Colorectal cancer (CRC) accounts for 9% of all new cancer cases worldwide and affects over 1 million people each year. Screening can reduce the mortality associated with the disease, yet participation rates are suboptimal. Compliers with CRC screening are less deprived; they have higher education than noncompliers and tend to be male, white and married. Likely reasons for nonparticipation encompass several 'modifiable' factors that could be targeted in interventions aimed at increasing participation rates. Successful intervention strategies include organizational changes, such as increasing access to fecal occult blood test (FOBT) kits, providing reminders to healthcare providers or users about screening opportunities, and educational strategies to improve awareness and attitudes towards CRC screening. Multifactor interventions that target more than one level of the screening process are likely to have larger effects. The biggest challenge for future research will be to reduce inequalities related to socio-economic position and ethnicity in the uptake of screening.

Intervention to increase recommendation and delivery of screening for breast, cervical, and colorectal cancers by healthcare providers a systematic review of provider reminders

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet, not all people who should be screened are screened regularly or, in some cases, ever. This report presents results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of provider reminder/recall interventions to increase screening for breast, cervical, and colorectal cancers. These interventions involve using systems to inform healthcare providers when individual clients are due (reminder) or overdue (recall) for specific cancer screening tests. Evidence in this review of studies published from 1986 through 2004 indicates that reminder/recall systems can effectively increase screening with mammography, Pap, fecal occult blood tests, and flexible sigmoidoscopy. Additional research is needed to determine if provider reminder/recall systems are effective in increasing colorectal cancer screening by colonoscopy. Specific areas for further research are also suggested.

Factors in quality care--the case of follow-up to abnormal cancer screening tests--problems in the steps and interfaces of care

To achieve the benefit of cancer screening, appropriate follow-up of abnormal screening test results must occur. Such follow-up requires traversing the transition between screening detection and diagnosis, including several steps and interfaces in care. This article reviews factors and interventions associated with follow-up of abnormal tests for cervical, breast and colorectal cancers. We synthesized 12 reviews of descriptive and intervention studies published between 1980 and 2008. There was wide variability in definition of follow-up, setting, study population, and reported prevalence rates. Correlates of follow-up included patient characteristics (eg, knowledge and age), social support, provider characteristics, practice (eg, having reminders systems), community and professional norms (eg, quality measures), and policy (eg, federal programs). Effective interventions included patient education and support; delivery systems design changes, such as navigation; and information system changes, most notably patient tracking and physician reminders. Few studies focused explicitly on interfaces and steps of care, such as communication between primary care and specialists, or simultaneously targeted the multilevel factors that affect care. Future practice and research priorities should include development of clear operational definitions of the steps and interfaces related to patients, providers, and organizations; reflect evolving guidelines and new technologies; determine priorities for intervention testing; and improve measures and apply appropriate study designs.

Integrating theory into community interventions to reduce liver cancer disparities: The Health Behavior Framework

Mitigating the unequal burden of cancer often involves conducting community-based trials to develop effective intervention strategies to promote cancer-related health behaviors. However, this is challenging due to the simultaneous influence of numerous factors, at multiple levels in the socio-ecological context, on health behavior. A sound conceptual framework can bring order to this complex environment and provide a roadmap for systematically addressing the multiple determinants of the behavior in question. This paper describes the application of The Health Behavior Framework, an integrative conceptual model, in an ongoing Program Project, "Liver Cancer Control Interventions for Asian-Americans." The Framework has been integral to shaping all aspects of the three component research trials from selection of the study designs to development of the interventions and data collection instruments. We advocate universal adoption of theory into community-based intervention research as a way to accelerate our ability to develop effective interventions and facilitate synthesis of study results across populations and behavioral outcomes: critical steps in advancing the field of health disparities research.

Screening mammography: a cross-sectional study to compare characteristics of women aged 40 and older from the deep South who are current, overdue, and never screeners

PURPOSE

We sought to identify unique barriers and facilitators to breast cancer screening participation among women aged 40 and older from Mississippi who were categorized as current, overdue, and never screeners.

METHODS

Cross-sectional data from a 2003 population-based survey with 987 women aged 40 and older were analyzed. Chi-square analysis and multinomial logistic regression examined how factors organized under the guidance of the Model of Health Services Utilization were associated with mammography screening status.

RESULTS

Nearly one in four women was overdue or had never had a mammogram. Enabling factors, including poor access to care (no annual checkups, no health insurance) and to health information, lack of social support for screening, and competing needs, were significantly associated with being both overdue and never screeners. Pertaining to factors unique to each screening group, women were more likely to be overdue when they had no usual source of health care and believed that treatment was worse than the disease. In turn, women were more likely to be never screeners when they were African American, lacked a provider recommendation for screening, and held the fatalistic view that not much could be done to prevent breast cancer.

CONCLUSION

Similar and unique factors impact utilization of mammography screening services among women. Those factors could inform efforts to increase screening rates.

How do physician assessments of patient preferences for colorectal cancer screening tests differ from actual preferences? A comparison in Canada and the United States using a stated-choice survey

BACKGROUND

Patient preferences can affect colorectal cancer (CRC) screening test use. We compared utility-based preferences for alternative CRC screening tests from a stated-preference discrete-choice survey of the general population and physicians in Canada and the United States.

METHODS

General population respondents (Canada, n = 501; US, n = 1087) participated in a survey with 12 choice scenarios and 9 CRC screening test attributes. Physicians (n = 100, both Canada and US) reported expected patient preferences. We estimated relative importance of attributes using bivariate probit regression analysis and calculated willingness-to-pay for various CRC screening tests.

RESULTS

In 28 and 31% of scenarios, Canadian and US respondents, respectively, chose no screening over a hypothetical test. Canadian (45%) and US (46%) physicians expected patients to choose no screening more often. For all groups the most important attribute was sensitivity, but physicians' perception of patients' preferences are significantly different from actual preferences. Other key attributes are those related to test performance or the testing process. Fecal DNA, colonoscopy, and virtual colonoscopy were the most preferred tests by all groups, but respondents were willing-to-pay more than physicians predicted.

CONCLUSION

Physicians' perception of patients' preferences are quite different from those of the general population. However, among general population and physicians, Canadian and US preferences were similar.

Self-identity after cancer: "survivor", "victim", "patient", and "person with cancer"

BACKGROUND

Living through cancer often involves developing new identities which may strongly influence well-being and relationships with care providers, yet little is currently known about these post-cancer identities.

OBJECTIVES

To examine (1) the extent to which four post-cancer identities (patient, person who has had cancer, victim, and survivor) are adopted, (2) relations between each identity and involvement in cancer-related activities and mental and physical well-being, and (3) correlates of these identities.

DESIGN

Cross-sectional questionnaire-based study.

PARTICIPANTS

168 young to middle-aged adults who had previously experienced cancer.

MEASUREMENTS

Cancer identifications, background variables, psychological functioning, cancer risk appraisals and coping, cancer-related activities, and mental and physical well-being.

RESULTS

At least somewhat, 83% endorsed survivor identity, 81% identity of "person who has had cancer", 58% "patient", and 18% "victim". Identities were minimally correlated with one another and differentially associated with involvement in cancer-related activities. Survivor and person who has had cancer identities correlated with involvement in most cancer-related activities such as wearing cancer-related items and talking about prevention (ps < 0.5). Survivor identity correlated with better psychological well-being and post-traumatic growth, victim identity with poorer well-being (ps < 0.5); neither identifying as a patient nor a person with cancer was related to well-being. Through regression analyses, identities were shown to be explained by unique combination of background, functioning, appraisal and coping variables.

CONCLUSIONS

Survivor identity appears most common and most associated with active involvement and better psychological well-being, but other identifications are also common and simultaneously held. Adoption of specific cancer identities is likely to impact interactions with health care providers, including those in general internal medicine, and health behavior changes.

Effect of a multimodal reminder program on repeat mammogram screening

BACKGROUND

Patient mammogram reminders are effective but have not been fully implemented in practice to improve routine screening. The effectiveness of implementation and maintenance phases of a multimodal reminder program that incorporated automated calls capable of efficiently reaching large numbers of women was evaluated to improve repeat mammography screening.

DESIGN

A quasi-experimental study was conducted in 2008 using electronic medical record data during three time periods: pre-reminder phase (2004), post-reminder implementation phase (2006), and post-reminder maintenance phase (January 1-July 1, 2007).

SETTING/PARTICIPANTS

Participants were female Kaiser Permanente Northwest HMO members aged 42 years or more who were 20 months past their last mammogram (index date) (N=35,104). The intervention program targeted women aged 50-69 years. Women aged 42-49 years (for whom clinical guidelines also recommend mammography) not targeted by the program constituted the primary comparison group (CG1).

INTERVENTION

A "mammogram due soon" postcard was mailed to participants 20 months after their last mammogram, followed by up to two automated phone calls and one live call for nonresponders.

MAIN OUTCOME MEASURES

The outcome measure was the time until participants received a mammogram in the 10 months following the index date.

RESULTS

Pre-reminder, 63.4% of targeted women completed a mammogram; this number increased to 75.4% in the post-reminder implementation phase; 80.6% completed a mammogram in the maintenance phases. After controlling for demographics and clinic visits, intervention women were 1.51 times more likely to complete a mammogram (CI=1.40, 1.62) post-reminder implementation, compared to CG1. The effect was maintained in 2007 (hazard ratio 1.81, CI=1.65, 1.99).

CONCLUSIONS

The study found that this multimodal reminder system could be effectively implemented and maintained in a large health system. If widely implemented, this intervention could substantially improve community mammography screening.

Embodiment and breast cancer among African American women

African American women have historically been screened for breast cancer less than other women, contributing to higher mortality rates. Previous research has focused on social and cultural factors, such as discrimination and religiosity, as shaping African American women's screening practices. This article extends this research by (a) examining the decisions and justifications of African American women with regard to screening practices, and (b) using a theoretical focus on embodiment to better understand women in relation to their own bodies. Ethnographic research consisted of 5 months of participant observation at an Indiana (USA) breast cancer care center, and 15 in-depth, semi-structured interviews along the continuum of screening practices. The results showed that embodied understandings of the body, personal (rather than biomedical) considerations of screening and treatment, and the quality of doctor/patient interactions all play a significant role in women's decisions about whether to screen for breast cancer or not. Based on these results and a review of the literature, six ways to include embodiment in public health initiatives are outlined.

Does patient health and hysterectomy status influence cervical cancer screening in older women?

BACKGROUND

Decisions to screen older patients for cancer are complicated by the fact that aging populations are heterogeneous with respect to life expectancy.

OBJECTIVE

To examine national trends in the association between cervical cancer screening and age, health and hysterectomy status.

DESIGN AND PARTICIPANTS

Cross-sectional data from the 1993, 1998, 2000, and 2005 National Health Interview Surveys (NHIS) were used to examine trends in screening for women age 35-64 and 65+ years of age. We investigated whether health is associated with Pap testing among older women using the 2005 NHIS (N = 3,073). We excluded women with a history of cervical cancer or who had their last Pap because of a problem.

MEASUREMENTS

The dependent variable was having a Pap test within the past 3 years. Independent variables included three measures of respondent health (the Charlson comorbidity index (CCI), general health status and having a chronic disability), hysterectomy status and sociodemographic factors.

MAIN RESULTS

NHIS data showed a consistent pattern of lower Pap use among older women (65+) compared to younger women regardless of hysterectomy status. Screening also was lower among older women who reported being in fair/poor health, having a chronic disability, or a higher CCI score (4+). Multivariate models showed that over 50% of older women reporting poor health status or a chronic disability and 47% with a hysterectomy still had a recent Pap.

CONCLUSIONS

Though age, health and hysterectomy status appear to influence Pap test use, current national data suggest that there still may be overutilization and inappropriate screening of older women.

Interventions to increase recommendation and delivery of screening for breast, cervical, and colorectal cancers by healthcare providers systematic reviews of provider assessment and feedback and provider incentives

Most major medical organizations recommend routine screening for breast, cervical, and colorectal cancers. Screening can lead to early detection of these cancers, resulting in reduced mortality. Yet not all people who should be screened are screened, either regularly or, in some cases, ever. This report presents results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of two provider-directed intervention approaches to increase screening for breast, cervical, and colorectal cancers. These approaches, provider assessment and feedback, and provider incentives encourage providers to deliver screening services at appropriate intervals. Evidence in these reviews indicates that provider assessment and feedback interventions can effectively increase screening by mammography, Pap test, and fecal occult blood test. Health plans, healthcare systems, and cancer control coalitions should consider such evidence-based findings when implementing interventions to increase screening use. Evidence was insufficient to determine the effectiveness of provider incentives in increasing use of any of these tests. Specific areas for further research are suggested in this report, including the need for additional research to determine whether provider incentives are effective in increasing use of any of these screening tests, and whether assessment and feedback interventions are effective in increasing other tests for colorectal cancer (i.e., flexible sigmoidoscopy, colonoscopy, or double-contrast barium enema).

A critical review of theory in breast cancer screening promotion across cultures

This article reviews the contribution and potential of widely used health behavior theories in research designed to understand and redress the disproportionate burden of breast cancer borne by diverse race/ethnic, immigrant, and low-income groups associated with unequal use of mammography. We review the strengths and limitations of widely used theories and the extent to which theory contributes to the understanding of screening disparities and informs effective intervention. The dominant focus of most theories on individual cognition is critically assessed as the abstraction of behavior from its social context. Proposed alternatives emphasize multilevel ecological approaches and the use of anthropologic theory and methods for more culturally grounded understandings of screening behavior. Common and alternative treatments of fatalism exemplify this approach, and descriptive and intervention research exemplars further highlight the integration of screening behavior and sociocultural context.

Determinants of cancer health disparities: barriers to cancer prevention, screening, diagnosis and treatment

BACKGROUND

Many health disparities occur when beneficial medical interventions are not shared by all.

OBJECTIVE

To examine the barriers that cause the disparities.

METHODS

In terms of obtaining beneficial medical interventions, the individual with disparities is influenced by his/her community, healthcare provider and healthcare system. The determinants of cancer health disparities include cultural, socio-economic and environmental factors, and the effects of social injustice.

RESULTS/CONCLUSION

These factors create inadequate information and knowledge about cancer, risk-promoting behaviors, inadequate conditions for seeking medical procedures, diminished access to and use of healthcare and inadequate healthcare services. The use of patient navigators may serve to address many of these factors.

The effects of teamwork and system support on colorectal cancer screening in primary care practices

BACKGROUND

While cancer screening is generally increasing in the U.S., colorectal cancer (CRC) screening remains low. Most CRC screening interventions focus either on patients or individual clinicians without examining the office context in which CRC screening is implemented. This study examines whether primary care practices that involve staff in general forms of health education have higher CRC screening rates than practices that do not.

METHODS

Cross-sectional data from 22 New Jersey and Pennsylvania family medicine practices were analyzed. Data include chart audits for 795 men and women eligible for CRC screening (age 50-70) and practice information surveys for each practice. Generalized estimating equations were used to determine CRC screening correlates.

RESULTS

Overall, 31.3% (n=249) of patients received CRC screening. Practices that reported using nursing or health educator staff to provide behavioral counseling to patients on topics such as diet, exercise or tobacco use were significantly more likely to also have higher CRC screening rates (z=7.30, p<0.0001). Their patients had 2.96 times increased odds of CRC screening than those in other practices (95% C.I., 2.21-3.96). Reminder system use was also associated with higher CRC screening (z=4.96, p<0.0001). In practices that used reminder systems, patients had 2.57 times increased odds of CRC screening than others (95% C.I., 1.77-3.74).

CONCLUSIONS

These findings suggest that interventions to achieve better CRC screening rates do not need to focus solely on CRC. Higher CRC rates may be achieved by capitalizing on the enhancing contributions of non-physician practice members providing more general health behavior change patient education.

Correlates of screening sigmoidoscopy use among men in a large nonprofit health plan

BACKGROUND

As the majority of patients diagnosed with colorectal cancer have no known risk factors, regular screening is strongly recommended. The authors examined factors associated with screening sigmoidoscopy use among participants in the California Men's Health Study (CMHS).

METHODS

The authors conducted a cross-sectional study over a 5-year period nested within a prospective cohort study. The CMHS enrolled a large multiethnic cohort (n = 84,170) of men from 2 major California health plans. Because screening sigmoidoscopy was the preferred and most commonly used test for patients at average risk of colorectal cancer in the health plans, the authors excluded from the analysis men who completed a barium enema colonoscopy or a fecal occult blood test.

RESULTS

Eligible subjects included 39,559 men at average risk for colorectal cancer. Prevalence of screening sigmoidoscopy use decreased with older age and increased with higher education and household income over the 5-year study period. Compared with whites, Asians (adjusted OR, 1.42; 95% CI, 1.30-1.56) and African Americans (adjusted OR, 1.18; 95% CI, 1.08-1.29) were more likely to undergo screening sigmoidoscopy. Screening increased with the number of outpatient visits and with having a primary care provider in internal medicine. Men who did not undergo prostate-specific antigen testing were also less likely to undergo sigmoidoscopy screening. Only 24.5% of current smokers had a screening sigmoidoscopy examination and were 25% less likely to undergo this procedure compared with nonsmokers (adjusted OR, 0.75; 95% CI, 0.69-0.82).

CONCLUSIONS

In this insured population for whom financial barriers are minimized, screening sigmoidoscopy use was as low as reported in the general population. However, minority patients were not less likely to be screened.

Improving colorectal cancer screening in primary care practice: innovative strategies and future directions

Colorectal cancer (CRC) screening has been supported by strong research evidence and recommended in clinical practice guidelines for more than a decade. Yet screening rates in the United States remain low, especially relative to other preventable diseases such as breast and cervical cancer. To understand the reasons, the National Cancer Institute and Agency for Healthcare Research and Quality sponsored a review of CRC screening implementation in primary care and a program of research funded by these organizations. The evidence base for improving CRC screening supports the value of a New Model of Primary Care Delivery: 1. a team approach, in which responsibility for screening tasks is shared among other members of the practice, would help address physicians' lack of time for preventive care; 2. information systems can identify eligible patients and remind them when screening is due; 3. involving patients in decisions about their own care may enhance screening participation; 4. monitoring practice performance, supported by information systems, can help target patients at increased risk because of family history or social disadvantage; 5. reimbursement for services outside the traditional provider-patient encounter, such as telephone and e-mail contacts, may foster enhanced screening delivery; 6. training opportunities in communication, cultural competence, and use of information technologies would improve provider competence in core elements of screening programs. Improvement in CRC screening rates largely depends on the efforts of primary care practices to implement effective systems and procedures for screening delivery. Active engagement and support of practices are essential for the enormous potential of CRC screening to be realized.

Inadequacy of cervical cancer screening among urban recent immigrants: a population-based study of physician and laboratory claims in Toronto, Canada

OBJECTIVE

In Canada, Pap smears are recommended from 18 to 69. Self-reported socioeconomic gradients in screening have been documented in North America but there have been few direct measures of Pap smear use among immigrants or socially disadvantaged groups. Our purpose was to investigate whether socioedemographic factors are related to cervical cancer screening in Toronto, Canada.

METHOD

Pap smears were identified using fee and laboratory codes in Ontario physician service claims for 3 years (2000-2002 inclusive) for women aged 18-66. Area-level socioeconomic factors were derived from the 2001 census. At the individual level, recent registrants for health coverage, over 80% of whom are expected to be recent immigrants, were identified as women first registering after January 1, 1993.

RESULTS

Among 724,584 women, 55.4% had Pap smears within 3 years. Recent immigration, visible minority, foreign language, low income and low education were all associated with significantly lower area rates. Recent registrants had much lower rates than non-recent registrants (36.9% versus 60.9%).

CONCLUSION

Pap smear rates in Toronto fall below those dictated by evidence-based practice. Recent registrants, a largely immigrant group, have particularly low rates. Efforts to improve coverage need to emphasize women who recently immigrated and those with socioeconomic disadvantage.

Patient acceptance of a novel preventive care delivery system

OBJECTIVE

To determine patient acceptance of a preventive care model employing outreach by non-physician experts outside of clinic visits.

METHODS

Questionnaire completed in 2005 by patients in the waiting room of an academic general medicine practice associated with the University of Colorado Health Sciences Center. Topics included the role of primary care providers in coordinating health care; interest in being contacted by non-PCPs between visits; and willingness to communicate with such experts by phone, e-mail, and internet.

RESULTS

95% of the patients completed the survey (n=354). 93% of these affirmed either that requiring primary care provider involvement in preventive health care is not always necessary, is inconvenient, or represents an unnecessary expense. More than 70% were open to a non-PCP-centered method of receiving preventive services. Socioeconomically disadvantaged patients and those with poorer self-rated health, however, were less likely to express interest in the concept.

CONCLUSION

Our patients were open to a non-traditional model of delivering preventive care. This model could improve delivery of preventive services. In instituting this system, it would be important to pay close attention to the concerns of vulnerable populations.

Cancer screening in women: body mass index and adherence to physician recommendations

BACKGROUND

The reasons that obese women are less likely to obtain mammograms and Papanicolaou tests (Pap smears) are poorly understood. This study evaluated associations between body mass index (BMI) and receipt of and adherence to physician recommendations for mammography and Pap smear.

METHODS

Data from the 2000 National Health Interview Survey (8289 women aged 40 to 74 years) were analyzed in 2006 using logistic regression. Women with previous hysterectomy were excluded from Pap smear analyses (n=5521). Outcome measures were being up-to-date with screening, receipt of physician recommendations, and women's adherence to physician recommendations for mammography and Pap smear.

RESULTS

After adjusting for sociodemographic variables, healthcare access, health behaviors, and comorbidity, severely obese women (BMI > 40 kg/m(2)) were less likely to have had mammography within 2 years (odds ratio [OR]=0.50, 95% confidence interval [CI]=0.37-0.68) and a Pap smear within 3 years (OR=0.43, 95% CI=0.27-0.70). Obese women were as likely as normal-weight women to receive physician recommendations for mammography and Pap smear. Severely obese women were less likely to adhere to physician recommendations for mammography (OR=0.49, 95% CI=0.32-0.76). Women in all obese categories (BMI > 30 kg/m(2)) were less likely to adhere to physician recommendations for Pap smear (ORs ranged from 0.17 to 0.28, p<0.001).

CONCLUSIONS

Obese women are less likely to adhere to physician recommendations for breast and cervical cancer screening. Interventions focusing solely on increasing physician recommendations for mammography and Pap smears will probably be insufficient for obese women. Additional strategies are needed to make cancer screening more acceptable for this high-risk group.

Which women aren’t getting mammograms and why? (United States)

OBJECTIVE

This study investigates why women who reported no recent mammogram did not get the test.

METHODS

Using data from the 2000 National Health Interview Survey (NHIS), we examine correlates of mammography use among women 40 years and older (n = 10,212), with particular focus on the 30% (n = 3,188) who reported no recent mammogram. Non-screening is examined in the context of two important correlates of mammography use-access to health care and a physician's recommendation to get a mammogram.

RESULTS

In total, 80% of non-screeners who reported having access to healthcare did not receive a recommendation for a mammogram. Women age 65 years and older were more likely than younger women to report not receiving a recommendation (OR 1.77, 95% CI 1.25-2.50). For women who reported having access, non-screening was significantly more likely among younger women (40-49), those with less education, incomes less than 20,000 dollars, residence outside Metropolitan Statistical Areas (MSAs) and no family history of breast cancer. Among women with access problems, those who had not visited a primary care provider in the past year were much more likely to be non-screeners (80%) compared with those who had seen a provider (46%). Among women with access, those who reported put it off as the main reason for non-screening were significantly more likely to be younger and to be born in the U.S. than women who said that they didn't know they needed a mammogram.

CONCLUSIONS

Most non-screeners report not receiving a physician recommendation for mammography. Although a minority reported access problems, the effect of lacking access on utilization was strong and is accentuated when women without access do not see a doctor. These findings confirm the importance of a mammography recommendation and raise questions concerning whether this information is being conveyed by physicians or heard by patients.

Comparison of three interventions to increase mammography screening in low income African American women

BACKGROUND

Low-income African American women are more likely to die of breast cancer than their Caucasian counterparts, and at least part of the difference in mortality results from differential screening adherence. The purpose of this study was to identify more efficacious methods of promoting routine mammography screening in underserved populations.

METHODS

A prospective randomized intervention study of 344 low income African American women compared the impact of three interventions on mammography adherence and stage of readiness: (1) pamphlet only; (2) culturally appropriate video; and (3) interactive computer-assisted instruction program.

RESULTS

The interactive computer intervention program produced the greatest level of adherence to mammography (40.0%) compared to the video group (24.6%) and the pamphlet group (32.1%). When subjects in the pamphlet and video groups were combined to form a non-interactive group, this group had a significantly lower adherence than the group who received the interactive computer intervention (27.0% versus 40.0%). There was also significantly more forward movement in mammography stage of readiness among participants in the computer group (52.0%) compared to those in the pamphlet group (46.4%) or the video group (31.3%). When combining the non-interactive technology (pamphlet and video) there was also more forward movement in mammography stage of readiness for those in the interactive intervention group (52.0% moved 1 or 2 stages) compared to those in the non-interactive group (36.2%).

CONCLUSIONS

These data indicate that tailored approaches are more effective than targeted messages either in print or video format. Another finding of this study is that interactive interventions are more effective than non-interactive interventions in increasing adherence and moving African American women forward in their mammogram stage of readiness.

Improving Rescreening In Community Clinics: Does A System Approach Work?

Community clinics provide inadequate breast cancer screening services to low-income, racially- and ethnically-diverse communities. This study develops and evaluates the effectiveness of multifaceted organizational system interventions--operational assessments, tracking systems, reminder calls, tailored education, physician prompts and a tailored counseling call--on mammography rescreening rates within three community clinics. We used the Chronic Care Model and Put Prevention Into Practice framework to redesign breast screening delivery services within the California Cancer Detection Programs: Every Woman Counts (CDP:EWC), community clinic settings. We used a quasi-experimental design with a random selection of 400 patients at pre-intervention. To establish a post-intervention clinic's rescreening rate a new comparable cross-sectional random sample of 347 women was drawn. Measures A chart abstraction instrument was used to establish clinics' rescreening rates. Subjects participants at pre and post-intervention were low-income women 50 years of age and older who had received normal mammography results and had not been diagnosed with breast cancer in the last five years. General linear mixed model analysis revealed significant improvements for the organizational system redesign condition [pre-intervention rescreening rate: 32.1 percent v. post-intervention rescreening rate 50.2 percent, (p < .001)]. For the organizational system redesign plus tailored counseling call condition, there was maintenance in the rescreening rate following the intervention [pre-intervention: 44.4 percent v. post-intervention: 45.1 percent, (p > 0.05)]. Multilevel interventions directed at redesigning community clinics primary care breast cancer screening services, can improve mammography rescreening rates.

Promoting culturally appropriate colorectal cancer screening through a health educator: a randomized controlled trial

BACKGROUND

Colorectal cancer (CRC) is a leading cause of cancer mortality in the US. Surveys reveal low CRC screening levels among Asians in the US, including Chinese Americans.

METHODS

A randomized controlled trial was conducted with Chinese patients to evaluate a clinic-based, culturally and linguistically appropriate intervention promoting fecal occult blood test (FOBT) screening. The multifaceted intervention included a trilingual and bicultural health educator, bilingual materials (a video, a motivational pamphlet, an informational pamphlet, and FOBT instructions), and three FOBT cards. Patients in the control arm received usual care. Our primary outcome measure was FOBT screening within 6 months after randomization. The proportion of FOBT completion in the intervention and control arms was compared by using a chi-square test, and logistic regression analysis was performed to adjust for the effects of sociodemographic variables and prior screening history. Potential effect modifications were also tested by using logistic regression models.

RESULTS

Our intervention had a strong effect on FOBT completion (intervention group, 69.5%; control group, 27.6%), and the adjusted odds of FOBT slightly increased to over 6-fold greater in the intervention arm compared with the control arm. No effect modification by age, gender, language, insurance, or prior FOBT was found.

CONCLUSIONS

The authors' multifaceted, culturally appropriate intervention significantly increased FOBT screening in a group of low-income and less-acculturated minority patients. Given the large effect size, future research should determine the effective core component(s) that can increase CRC screening in both the general and minority populations.

Secondary prevention of cancer

OBJECTIVES

To review criteria for mass cancer screening among asymptomatic populations and barriers to secondary prevention of breast, cervical, and colorectal cancers. To describe challenges to implementing theoretically based interventions to increase appropriate cancer screening, follow-up, and surveillance.

DATA SOURCES

Published journal articles, text books, and epidemiologic reports.

CONCLUSION

Interventions to increase breast, cervical, and colorectal cancer screening participation must be approached from a systems perspective that includes patient, health care provider, and health care system variables.

IMPLICATIONS FOR NURSING PRACTICE

Understanding the array of factors that impede progress in the secondary prevention of cancer is necessary to improve care. Nurses have an important role in decreasing morbidity and mortality from breast, cervical, and colorectal cancers.

Results of a randomized controlled trial to increase colorectal cancer screening in a managed care health plan

BACKGROUND

Colorectal cancer (CRC) is the third most common cause of cancer deaths; however, rates of regular screening for this cancer are low. A quality improvement (QI) program to increase CRC screening was developed for use in a managed care health plan.

METHODS

Thirty-six provider organizations (POs) contracting with the health plan were recruited for a randomized controlled effectiveness trial testing the QI program. The intervention was delivered over a 2-year period, and its effectiveness was assessed by chart review of a random sample of patients from each PO.

RESULTS

Thirty-two of the 36 POs were evaluable for outcome assessment. During the 2-year intervention period, only 26% of the eligible patients received any CRC screening test. Twenty-nine percent of patients had any CRC screening test within guidelines, with no differences between the intervention or control POs. Significant predictors of having received CRC screening within guidelines were older age (P = 0.0004), receiving care in an integrated medical group (P < 0.0001) and having had a physical examination within the past 2 years (P < 0.0001).

CONCLUSIONS

A facilitated QI intervention program for CRC screening that focused on the PO did not increase rates of CRC screening. Overall CRC screening rates are low and are in need of improvement.

Toward a system of cancer screening in the United States: trends and opportunities

The hard work of public health officials, physicians, and disease advocacy groups to educate Americans about the importance of early detection has resulted in uptake of screening tests at levels equivalent to or higher than in countries with organized cancer screening programs. However, the societal costs of high screening rates are larger in the United States than in other countries, including higher prices for screening, more unnecessary testing, and inefficiencies in delivery, especially in small practices. Further, screening rates are not evenly distributed across population groups, and the national expenditure on clinical and community research to promote cancer screening among individuals has not been matched by research efforts that focus on policy or clinical systems to increase screening widely throughout the population. We identify opportunities for organizational change that improve access to use, improve quality, and promote cost effectiveness in cancer screening delivery.

Physician Recommendation for Papanicolaou Testing Among U.S. Women, 2000

OBJECTIVE

Many women in the U.S. undergo routine cervical cancer screening, but some women have rarely or never had a Papanicolaou (Pap) test. Studies of other cancer screening tests (for example, mammograms) have shown that physician recommendation to get a screening test is one of the strongest predictors of cancer screening.

METHODS

In this study, we examined whether women in the U.S. had received a physician recommendation to get a Pap test using data from the 2000 National Health Interview Survey. Reported reasons for not receiving a Pap test were also explored.

RESULTS

Among women aged > or =18 years who had no history of hysterectomy, 83.3% [95% confidence interval (CI), 82.4-84.1%] of the 13,636 women in this sample had had a Pap test in the last 3 years. Among 2,310 women who had not had a recent Pap test, reported reasons for not receiving a Pap test included: "No reason/never thought about it" (48.0%; 95% CI, 45.5-50.7), "Doctor didn't order it" (10.3%; 95% CI, 8.7-12.0), "Didn't need it/didn't know I needed this type of test" (8.1%; 95% CI, 6.7-9.6), "Haven't had any problems" (9.0%; 95% CI, 7.6-10.5), "Put it off" (7.4%; 95% CI, 6.2-8.7), "Too expensive/no insurance" (8.7%; 95% CI, 7.3-10.2), "Too painful, unpleasant, embarrassing" (3.5%; 95% CI, 2.5-4.6), and "Don't have doctor" (1.7%; 95% CI, 1.2-2.4). Among women who had had a doctor visit in the last year but who had not had a recent Pap test, about 86.7% (95% CI, 84.5-88.6) reported that their doctor had not recommended a Pap test in the last year. African-American women were as likely as White women to have received a doctor recommendation to get a Pap test. Hispanic women were as likely as non-Hispanic women to have received a doctor recommendation to get a Pap test. In multivariate analysis, factors positively associated with doctor recommendation to get a Pap test included being aged 30 to 64 years, having been born in the U.S., and having seen a specialist or general doctor in the past year.

CONCLUSION

These findings suggest that lack of a physician recommendation contributes to underuse of Pap screening by many eligible women. Given research that shows the effectiveness of physician recommendations in improving use, increased physician recommendations could contribute significantly to increased Pap screening use in the U.S.

Knowledge of oral cancer risk factors and diagnostic concepts among North Carolina dentists

BACKGROUND

Dentists play a critical role in the early detection of oral and pharyngeal cancer (OPC). The authors administered a survey that assessed the level of knowledge among dentists regarding risk factors and diagnostic concepts.

METHODS

In 2002, the authors mailed a 38-item, pretested survey to a random sample of 1,115 licensed dentists practicing in North Carolina. Three-level (low, medium, high) composite index scores for knowledge of risk factors and diagnostic concepts were created using previously developed scales. The authors formulated multivariable models for risk factor and diagnostic knowledge indexes.

RESULTS

Of the 584 respondents, only 181 (31 percent) had consistent medium-to-high levels of knowledge on both highly correlated indexes. Dentists who had higher risk factor and diagnostic knowledge scores were significantly (P < .05) more likely to have heard of one or more diagnostic aids (odds ratio [OR], 2.7), to have graduated from dental school within the previous 20 years (OR, 1.8) and to have performed biopsies or referred five or more patients with suspicious lesions per year (OR, 1.7 and 1.5, respectively) than were less-knowledgeable respondents.

CONCLUSIONS

More education is needed in dental schools, postgraduate programs and continuing education programs to enhance dental professionals' knowledge of OPC risk factors and diagnostic concepts. Such programs should include information about adjunctive diagnostic aids.

PRACTICE IMPLICATIONS

Greater knowledge of risk factors and diagnostic concepts may result in more frequent patient referrals, biopsy procedures or both, thus aiding in the early diagnosis and treatment of patients with OPC.

Lessons learned from community-based cancer screening intervention research

Behaviors associated with cancer screening have been the focus of intensive research over the past 2 decades, primarily in the form of intervention trials to improve screening based in both clinical and community settings. Meta-analyses and literature reviews have synthesized and organized the resulting literature. From the accumulated work, this review distilled lessons learned from cancer screening intervention research in community settings. The authors posed the question, "What do we know about the development of effective community-based interventions (the level of good over harm achieved in real-world conditions)?" Framed around the concept of focal points (the simultaneous combination of target population, behavioral objective, and setting for an intervention), 13 lessons were derived. One lesson was cross-cutting, and the other lessons addressed the three focal-point components and the major intervention categories (access-enhancing strategies, mass media, small media, one-on-one and small-group education, and combinations of these categories). To build more systematically on existing research, recommendations are made for new directions in basic behavioral and intervention research.

Disseminating effective cancer screening interventions

A large gap exists between the results of research concerning efficacious cancer screening programs and the programs delivered in practice. In this article, the authors discuss issues in, barriers to, and lessons learned regarding the dissemination of interventions. They summarize previous reviews, exemplary studies, and theories regarding the diffusion and dissemination of cancer screening interventions. Six lessons learned address the involvement of key stakeholders, factors influencing diffusion, the need for different types of efficacy and effectiveness studies with greater attention to external validity, replication, the use of theoretical and evaluation models, and the importance of policy infrastructure. In this article, the authors make recommendations for future research and practice, including improving the understanding of the intervention process and changing the types of grants funded and review criteria used. Also needed are an enhanced infrastructure, including policies to support dissemination, and the involvement of researchers, health care administrators, clinicians, and funding organizations in dissemination if the gap between research and practice in cancer screening is to be reduced.

Examining the cost-effectiveness of cancer screening promotion

Cost-effectiveness analyses (CEAs) can help to quantify the contribution of the promotion of a screening program to increased participation in screening. The cost-effectiveness (C/E) of screening promotion depends in large part on the endpoints of interest. At the most fundamental level, the C/E of a strategy for promoting screening would focus on the attendance rate, or cost per person screened, and the C/E would be influenced by the costs of promotion, as well as by the size and responsiveness of the target population. In addition, the costs of screening promotion (measured as the cost per additional participant in screening) can be included in a CEA estimate of the screening technology. In this case, depending on the efficacy of the screening test and the costs and influence of the promotion, the C/E of screening may improve or become poorer. In the current study, the authors reviewed the literature on the C/E of cancer screening promotion. The following lessons were learned regarding the C/E of screening and its promotion: 1) high-quality information on the C/E of screening is increasingly available; 2) cost-effective promotion of screening is dependent on cost-effective screening strategies; 3) quality-of-life effects may be important in assessing the overall C/E of screening programs; 4) research efforts aimed at identifying cost-effective approaches to screening promotion are useful but sparse; 5) C/E studies should be better incorporated into well designed effectiveness research efforts; 6) variations in C/E according to intervention characteristics, population characteristics, and context should be evaluated in greater depth; 7) the long-term effects of screening promotion are critical to assessing C/E; 8) the effects of promotion on costs of screening must be better understood; and 9) CEA must be interpreted in light of other information. The authors showed that CEA can be a valuable tool for understanding the merits of health promotion interventions and that CEA is particularly valuable in identifying screening strategies that might be promoted most cost-effectively.

The future of research that promotes cancer screening

The authors draw on the lessons highlighted in preceding articles in the current supplement to provide recommendations for cancer screening intervention research and to highlight some of the many questions that will require further investigation.
