Effectiveness of health education to increase screening for cervical cancer among eastern-band Cherokee Indian women in North Carolina

American Indian and Alaska Native recruitment strategies for health-related randomized controlled trials: A scoping review

BACKGROUND

Significant health disparities exist among American Indian and Alaska Natives (AI/ANs), yet AI/ANs are substantially underrepresented within health-related research, including randomized controlled trials (RCTs). Although research has previously charted representation inequities, there is however a gap in the literature documenting best practice for recruitment techniques of AI/ANs into RCTs. Therefore, the aim of this review was to systematically gather and analyze the published literature to identify common strategies for AI/AN participant recruitment for RCTs in the US.

METHODS

A scoping review methodology was engaged with a systematic search operationalized within relevant databases to February 19, 2022, with an additional updated search being carried out up until January 1, 2023: PubMed, Embase, Web of Science, PsycINFO, CINAHL, and Google Scholar. A two-stage article review process was engaged with double reviewers using Covidence review software. Content analysis was then carried out within the included articles by two reviewers using NVivo software to identify common categories within the data on the topic area.

RESULTS

Our review identified forty-one relevant articles with the main categories of recruitment strategies being: 1) recruitment methods for AI/ANs into RCTs (passive advertising recruitment approaches, individual-level recruitment approaches, relational methods of recruitment); 2) recruitment personnel used within RCTs; and, 3) relevant recruitment setting. The majority of the included studies used a culturally relevant intervention, as well as a community-involved approach to operationalizing the research.

CONCLUSION

Increasing AI/AN representation in RCTs is essential for generating evidence-based interventions that effectively address health disparities and improve health outcomes. Researchers and funding agencies should prioritize the engagement, inclusion, and leadership of AI/AN communities throughout the RCT research process. This includes early community involvement in study design, implementation of culturally tailored recruitment strategies, and dissemination of research findings in formats accessible to AI/AN communities.

Women's decision to adopt or not adopt cervical cancer screening: Application of precaution adoption process model as the theoretical framework

BACKGROUND

The cancer is uncontrolled growth and spread of cells that affect almost all parts of the body. One of the most prevalent cancers in the female genital system is cervical cancer. The aim of present study was to determine the effect of educational intervention using the Precaution Adoption Process Model (PAPM) on cervical cancer screening behavior (Pap smear test) among women.

MATERIALS AND METHODS

In this interventional study that was done in Karaj health centers (2016), women (aged 15-49 years) were in the third stage of behavior change process based on PAPM randomly assigned to experimental and control groups. The data collection tool was a PAPM-based questionnaire whose validity and reliability were confirmed. Gathered data were analyzed using statistical software SPSS 16 and statistical tests (t-test, repeated measures analysis of variance, and Wilcoxon, Chi-squared, Fisher's exact, and Mann-Whitney tests).

RESULTS

The result showed that the stages of the decision-making process between the two groups were significantly different at the time immediately and 2 months after the intervention (P > 0.001). Also the results of the intervention based on the health belief model health belief model (HBM) components, regarding variables of knowledge, perceived susceptibility, perceived benefits, perceived barriers, and subjective norms, the mean scores in the experimental group were significantly different between the three sections before, immediately, and 2 months after the intervention (P > 0.001).

CONCLUSIONS

This study provides hints how persons could be influenced to move from the "Deciding about action" positions into to the stages of decided to act, adoption, and maintenance for promoting cervical cancer screening behavior.

Interventions targeted at women to encourage the uptake of cervical screening

BACKGROUND

This is an update of the Cochrane review published in Issue 5, 2011. Worldwide, cervical cancer is the fourth commonest cancer affecting women. High-risk human papillomavirus (HPV) infection is causative in 99.7% of cases. Other risk factors include smoking, multiple sexual partners, the presence of other sexually transmitted diseases and immunosuppression. Primary prevention strategies for cervical cancer focus on reducing HPV infection via vaccination and data suggest that this has the potential to prevent nearly 90% of cases in those vaccinated prior to HPV exposure. However, not all countries can afford vaccination programmes and, worryingly, uptake in many countries has been extremely poor. Secondary prevention, through screening programmes, will remain critical to reducing cervical cancer, especially in unvaccinated women or those vaccinated later in adolescence. This includes screening for the detection of pre-cancerous cells, as well as high-risk HPV. In the UK, since the introduction of the Cervical Screening Programme in 1988, the associated mortality rate from cervical cancer has fallen. However, worldwide, there is great variation between countries in both coverage and uptake of screening. In some countries, national screening programmes are available whereas in others, screening is provided on an opportunistic basis. Additionally, there are differences within countries in uptake dependent on ethnic origin, age, education and socioeconomic status. Thus, understanding and incorporating these factors in screening programmes can increase the uptake of screening. This, together with vaccination, can lead to cervical cancer becoming a rare disease.

OBJECTIVES

To assess the effectiveness of interventions aimed at women, to increase the uptake, including informed uptake, of cervical screening.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 6, 2020. MEDLINE, Embase and LILACS databases up to June 2020. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase uptake/informed uptake of cervical screening.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed risk of bias. Where possible, the data were synthesised in a meta-analysis using standard Cochrane methodology.

MAIN RESULTS

Comprehensive literature searches identified 2597 records; of these, 70 met our inclusion criteria, of which 69 trials (257,899 participants) were entered into a meta-analysis. The studies assessed the effectiveness of invitational and educational interventions, lay health worker involvement, counselling and risk factor assessment. Clinical and statistical heterogeneity between trials limited statistical pooling of data. Overall, there was moderate-certainty evidence to suggest that invitations appear to be an effective method of increasing uptake compared to control (risk ratio (RR) 1.71, 95% confidence interval (CI) 1.49 to 1.96; 141,391 participants; 24 studies). Additional analyses, ranging from low to moderate-certainty evidence, suggested that invitations that were personalised, i.e. personal invitation, GP invitation letter or letter with a fixed appointment, appeared to be more successful. More specifically, there was very low-certainty evidence to support the use of GP invitation letters as compared to other authority sources' invitation letters within two RCTs, one RCT assessing 86 participants (RR 1.69 95% CI 0.75 to 3.82) and another, showing a modest benefit, included over 4000 participants (RR 1.13, 95 % CI 1.05 to 1.21). Low-certainty evidence favoured personalised invitations (telephone call, face-to-face or targeted letters) as compared to standard invitation letters (RR 1.32, 95 % CI 1.11 to 1.21; 27,663 participants; 5 studies). There was moderate-certainty evidence to support a letter with a fixed appointment to attend, as compared to a letter with an open invitation to make an appointment (RR 1.61, 95 % CI 1.48 to 1.75; 5742 participants; 5 studies). Low-certainty evidence supported the use of educational materials (RR 1.35, 95% CI 1.18 to 1.54; 63,415 participants; 13 studies) and lay health worker involvement (RR 2.30, 95% CI 1.44 to 3.65; 4330 participants; 11 studies). Other less widely reported interventions included counselling, risk factor assessment, access to a health promotion nurse, photo comic book, intensive recruitment and message framing. It was difficult to deduce any meaningful conclusions from these interventions due to sparse data and low-certainty evidence. However, having access to a health promotion nurse and attempts at intensive recruitment may have increased uptake. One trial reported an economic outcome and randomised 3124 participants within a national screening programme to either receive the standard screening invitation, which would incur a fee, or an invitation offering screening free of charge. No difference in the uptake at 90 days was found (574/1562 intervention versus 612/1562 control, (RR 0.94, 95% CI: 0.86 to 1.03). The use of HPV self-testing as an alternative to conventional screening may also be effective at increasing uptake and this will be covered in a subsequent review. Secondary outcomes, including cost data, were incompletely documented. The majority of cluster-RCTs did not account for clustering or adequately report the number of clusters in the trial in order to estimate the design effect, so we did not selectively adjust the trials. It is unlikely that reporting of these trials would impact the overall conclusions and robustness of the results. Of the meta-analyses that could be performed, there was considerable statistical heterogeneity, and this should be borne in mind when interpreting these findings. Given this and the low to moderate evidence, further research may change these findings. The risk of bias in the majority of trials was unclear, and a number of trials suffered from methodological problems and inadequate reporting. We downgraded the certainty of evidence because of an unclear or high risk of bias with regards to allocation concealment, blinding, incomplete outcome data and other biases.

AUTHORS' CONCLUSIONS

There is moderate-certainty evidence to support the use of invitation letters to increase the uptake of cervical screening. Low-certainty evidence showed lay health worker involvement amongst ethnic minority populations may increase screening coverage, and there was also support for educational interventions, but it is unclear what format is most effective. The majority of the studies were from developed countries and so the relevance of low- and middle-income countries (LMICs), is unclear. Overall, the low-certainty evidence that was identified makes it difficult to infer as to which interventions were best, with exception of invitational interventions, where there appeared to be more reliable evidence.

The role of health education on cervical cancer screening uptake at selected health centers in Addis Ababa

Introduction

Cervical cancer is one of the most common causes of morbidity and mortality among women in developing countries including Ethiopia. Unlike other types of cancers, the grave outcomes of cervical cancer could be prevented if detected at its early stage. However, in Ethiopia, awareness about the disease and the availability of screening and treatment services is limited. This study aims to determine the role of health education on cervical cancer screening uptake in selected health facilities in Addis Ababa.

Methods

Two-pronged clustered randomized controlled trial was conducted in 2018 at eight public health centers that provide cervical cancer screening services using visual inspection with acetic acid (VIA) in Addis Ababa, Ethiopia. Each of the eight health centers were randomly assigned to serve as either an intervention or a control center. A two-pronged clustered randomized controlled trial was conducted in eight public health care centers. All the selected facilities provided cervical cancer screening services using visual inspection with acetic acid (VIA). Four health centers were randomly assigned to the intervention and control arms. The study participants were women aged 30–49 years who sought care at maternal and child health clinics but who had never been screened for cervical cancer. In the intervention health centers, all eligible women received one-to-one health education and educational brochures about cervical cancer and cervical cancer screening. In the control health centers, participants received standard care. Baseline data were collected at recruitment and follow-up data were collected two months after the baseline. For the follow-up data collection, participants (both in the intervention and control arms) were interviewed over the phone to check whether they were screened for cervical cancer.

Result

From the 2,140 women who participated in the study, 215 (10%) screened for cervical cancer, where 152(71%) were from the intervention health centers. Seventy-four percent of these participants reported that they learned about the benefits of screening from the one-to-one health education or the brochure. Women from the intervention health centers had higher odds of getting screened (AOR = 2.43,95%CI;1.58–2.90) than the controls. Women with the educational status of the first degree and those who have a history of sexually transmitted infections (STIs) had higher odds of getting screened (AOR = 2.03,95%CI;(1.15–2.58) and (AOR = 1.55,95%CI;1.01–2.36), respectively.

Conclusion and recommendation

Providing focused health education supported by printed educational materials increased the uptake of cervical cancer screening services. Integrating one-to-one health education and providing a take-home educational material into the existing maternal and child health services can help increase cervical cancer screening uptake.

Interventions to improve the uptake of screening across a range of conditions in Ethnic Minority Groups: a systematic review

BACKGROUND

Screening programmes are well established in cancer, and are now being implemented in other conditions. An effective screening programme leads to early disease detection and improved outcomes but its impact is dependent on the quality of the test and the proportion of the target population participating. A further consideration is that uptake of screening by minority groups is low.

PURPOSE

To determine which interventions have successfully increased screening uptake amongst minorities.

DATA SOURCES

Medline, Cochrane database and the grey literature were searched from 1990 to 1st March 2016.

STUDY SELECTION

Fifty-five English language studies that assessed uptake of screening in any minority population in the country of study aged over 18 years and that included a comparison arm.

DATA EXTRACTION

Independent data extraction was undertaken by two researchers (CK and MP), using a predesigned data extraction form (DEF) which assisted retrieval of the core contents of each study and the organisation of material.

DATA SYNTHESIS

Evidence was organised by screening test and type of intervention. Two authors (CK and MP) extracted data into evidence tables to enable comparison of study characteristics and findings. The heterogeneity of methods precluded a meta-analysis thus results are descriptive. Evidence was also assessed, using the Cochrane Collaboration risk of bias tables.

RESULTS

This systematic review appraises data from international studies on a variety of minority groups, interventions and screening programmes providing a narrative review of their success and limitations.

Effect of cervical cancer education and provider recommendation for screening on screening rates: A systematic review and meta-analysis

Background

Although cervical cancer is largely preventable through screening, detection and treatment of precancerous abnormalities, it remains one of the top causes of cancer-related morbidity and mortality globally.

Objectives

The objective of this systematic review is to understand the evidence of the effect of cervical cancer education compared to control conditions on cervical cancer screening rates in eligible women population at risk of cervical cancer. We also sought to understand the effect of provider recommendations for screening to eligible women on cervical cancer screening (CCS) rates compared to control conditions in eligible women population at risk of cervical cancer.

Methods

We used the PICO (Problem or Population, Interventions, Comparison and Outcome) framework as described in the Cochrane Collaboration Handbook to develop our search strategy. The details of our search strategy has been described in our systematic review protocol published in the International Prospective Register of systematic reviews (PROSPERO). The protocol registration number is CRD42016045605 available at: http://www.crd.york.ac.uk/prospero/display_record.asp?src=trip&ID=CRD42016045605. The search string was used in Pubmed, Embase, Cochrane Systematic Reviews and Cochrane CENTRAL register of controlled trials to retrieve study reports that were screened for inclusion in this review. Our data synthesis and reporting was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). We did a qualitative synthesis of evidence and, where appropriate, individual study effects were pooled in meta-analyses using RevMan 5.3 Review Manager. The Higgins I² was used to assess for heterogeneity in studies pooled together for overall summary effects. We did assessment of risk of bias of individual studies included and assessed risk of publication bias across studies pooled together in meta-analysis by Funnel plot.

Results

Out of 3072 study reports screened, 28 articles were found to be eligible for inclusion in qualitative synthesis (5 of which were included in meta-analysis of educational interventions and 8 combined in meta-analysis of HPV self-sampling interventions), while 45 were excluded for various reasons. The use of theory-based educational interventions significantly increased CCS rates by more than double (OR, 2.46, 95% CI: 1.88, 3.21). Additionally, offering women the option of self-sampling for Human Papillomavirus (HPV) testing increased CCS rates by nearly 2-fold (OR = 1.71, 95% CI: 1.32, 2.22). We also found that invitation letters alone (or with a follow up phone contact), making an appointment, and sending reminders to patients who are due or overdue for screening had a significant effect on improving participation and CCS rates in populations at risk.

Conclusion

Our findings supports the implementation of theory-based cervical cancer educational interventions to increase women’s participation in cervical cancer screening programs, particularly when targeting communities with low literacy levels. Additionally, cervical cancer screening programs should consider the option of offering women the opportunity for self-sample collection particularly when such women have not responded to previous screening invitation or reminder letters for Pap smear collection as a method of screening.

Effectiveness of a Colonia Educational Intervention

Assessment of the effectiveness of community-based health promotion programs is an essential component of accountability for both providers and funding agencies. The purpose of this study was to compare, in a colonia setting, the effects of an educational intervention for 7- to 12-year-old Hispanic children. The constructs of self-esteem and health locus of control were used as indices to compare differences between intervention participants and nonparticipants. Discriminate analysis revealed that powerful others’ locus of control, self-esteem, chance locus of control, and age distinguished intervention participants from nonparticipants. Results showed that the intervention positively affected self-esteem and influenced acceptance of responsibility for one’s own health.

Teaching tools to engage Anishinaabek First Nations women in cervical cancer screening: Report of an educational workshop

OBJECTIVE

To explore educational strategies for engaging First Nations women in Canada to attend cervical cancer screening.

DESIGN

Within a participatory action research framework, semi-structured interviews with health-care providers in First Nations communities revealed that education about the value of screening is perceived as being a key factor to promote cervical cancer screening.

SETTING

To obtain feedback from workshop informants, a 1-day educational workshop was held to identify appropriate educational intervention strategies, which would be applied in a forthcoming randomised controlled cervical screening trial.

METHODS

Common discussion and discussion groups, which were facilitated by a First Nations workshop moderator and a note taker.

RESULTS

This workshop helped to strengthen the ethical space dialogue with the First Nations communities with whom the study team had established research partnerships. The workshop atmosphere was relaxed and the invited informants decided that an educational health promotion event for community women needed to be held prior to inviting them to the cervical screening trial. Such an event would provide an opportunity to communicate the importance of attending regular cervical screening allowing women to make informed decisions about screening participation. Complementary promotional items, including an eye-catching pamphlet and storytelling, were also suggested.

CONCLUSION

The key messages from the events and promotional items can help to destigmatise women who develop a type of cancer that is caused by a sexually transmitted virus that affects both men and women. Developing and implementing positive health education that respectfully depicts female bodies, sexuality and health behaviours through a First Nations lens is strongly warranted.

Documenting Cancer Information Seeking Behavior and Risk Perception in the Hualapai Indian Community to Inform a Community Health Program

Cancer incidence among American Indians (AIs) is low, yet their 5-year relative survival rate is the second lowest of all U.S. populations. Culturally relevant cancer prevention education is key to achieve health equity. This collaborative project of the Hualapai Tribe and University of Arizona modified the National Cancer Institute's 2003 Health Information National Trends Survey (HINTS) to yield a more culturally relevant cancer information survey to document the health seeking behaviors and perceptions of cancer risks and preventability of AI adults residing in the Hualapai Indian community. A team of health care providers, educators and cancer survivors (six native and three non-natives) completed the adaptation. Four trained native surveyors administered the survey using a random household survey design. The Hualapai HINTS was well accepted (<5% refusal rate) and was completed by 205 adults (20.5% of all adult residents). Respondents reported a preference for and a trust in verbal cancer information and communication with health care professionals (77.1% preference; 57.4% trust) and at workshops (75.2% preference; 45.5% trust). Respondents were aware of some health behaviors associated with a reduced cancer risk, e.g., avoid tobacco use and need for screening. Respondents were less well informed about the role of diet and exercise. These findings were used to inform local cancer prevention education efforts and to develop a series of monthly workshops that engaged local health professionals to reinforce and discuss pathways of the primary role of lifestyle related factors, specifically diet and exercise in reducing cancer risk.

Factors associated with a positive attitude towards receiving cancer information: a population-based study in Spain

BACKGROUND

It is necessary to raise a positive attitude towards cancer information to improve disease prevention and control.

OBJECTIVE

To identify social factors, health characteristics and cancer-related perceptions and knowledge associated with a positive attitude towards cancer information.

DESIGN

We ran multivariate logistic regression models to analyse population-based data from OncoBarómetro-2010, a Spanish representative survey on perceptions and knowledge, related to cancer, conducted among 7938 people aged 18 years or more.

MEASUREMENT

Attitudes towards cancer information. A positive attitude includes feeling motivated to keep informed, to have screening tests or to change lifestyle. A negative attitude includes feeling indifference, concern, frustration or fear.

RESULTS

38.3% of the studied population reported having received information related to cancer (within the last 6 months). Among those, 31.5% expressed a negative attitude towards cancer information. People more likely to have a positive attitude towards cancer information (reference category: negative attitude) were people aged 35-74 (ref: aged 18-34) (P < 0.001) and cancer survivors (ref: those who had not had cancer) (OR: 3.05; 95% CI: 1.73-5.38). The likelihood of a positive attitude increased with the level of education (P < 0.001). The variables negatively associated with a positive attitude towards cancer information were poor self-rated health status (ref: fair) (OR: 0.63; 95% CI: 0.42-0.95) and high self-perceived risk of developing cancer (ref: low) (OR: 0.75; 95% CI: 0.60-0.92).

CONCLUSIONS

These findings have potential to inform programmes designed to promote cancer prevention behaviours. Policies should target population groups with low socio-economic groups, those with poor self-rated health and individuals with high self-perceived risk of cancer. Further, in order to increase knowledge of cancer symptoms, we need to focus on individuals with unhealthy lifestyles.

Strategies for Increasing Cervical Cancer Screening Amongst First Nations Communities in Northwest Ontario, Canada

The high burden of cervical cancer in Indigenous populations worldwide is due to underscreening and inadequate follow-up. Using qualitative, participatory action research, we interviewed health care staff to identify ways to increase screening recruitment in First Nations communities in Northwest Ontario, Canada. Our findings suggest the value of a multilevel social-ecological model to promote behavioral changes at the community, health care service and stakeholder, and decision-maker level. Participants emphasized the central role of First Nations women as nurturers of life and for the well-being of their family members. They stressed the importance of building awareness and motivation for cervical cancer screening through various activities including continuous education, hosting screening events specifically for women, improving the attitude and service of health care providers, and promoting screening tools and policies that complement and are respectful of First Nations women.

Community engagement to reduce inequalities in health: a systematic review, meta-analysis and economic analysis

Background

Community engagement has been advanced as a promising way of improving health and reducing health inequalities; however, the approach is not yet supported by a strong evidence base.

Objectives

To undertake a multimethod systematic review which builds on the evidence that underpins the current UK guidance on community engagement; to identify theoretical models underpinning community engagement; to explore mechanisms and contexts through which communities are engaged; to identify community engagement approaches that are effective in reducing health inequalities, under what circumstances and for whom; and to determine the processes and costs associated with their implementation.

Data sources

Databases including the Cochrane Database of Systematic Reviews (CDSR), The Campbell Library, the Database of Abstracts of Reviews of Effects (DARE), the Health Technology Assessment (HTA) database, the NHS Economic Evaluation Database (NHS EED) and EPPI-Centre’s Trials Register of Promoting Health Interventions (TRoPHI) and Database of Promoting Health Effectiveness Reviews (DoPHER) were searched from 1990 to August 2011 for systematic reviews and primary studies. Trials evaluating community engagement interventions reporting health outcomes were included.

Review methods

Study eligibility criteria: published after 1990; outcome, economic, or process evaluation; intervention relevant to community engagement; written in English; measured and reported health or community outcomes, or presents cost, resource, or implementation data characterises study populations or reports differential impacts in terms of social determinants of health; conducted in an Organisation for Economic Co-operation and Development (OECD) country. Study appraisal: risk of bias for outcome evaluations; assessment of validity and relevance for process evaluations; comparison against an economic evaluation checklist for economic evaluations. Synthesis methods: four synthesis approaches were adopted for the different evidence types: theoretical, quantitative, process, and economic evidence.

Results

The theoretical synthesis identified key models of community engagement that are underpinned by different theories of changes. Results from 131 studies included in a meta-analysis indicate that there is solid evidence that community engagement interventions have a positive impact on health behaviours, health consequences, self-efficacy and perceived social support outcomes, across various conditions. There is insufficient evidence – particularly for long-term outcomes and indirect beneficiaries – to determine whether one particular model of community engagement is likely to be more effective than any other. There are also insufficient data to test the effects on health inequalities, although there is some evidence to suggest that interventions that improve social inequalities (as measured by social support) also improve health behaviours. There is weak evidence from the effectiveness and process evaluations that certain implementation factors may affect intervention success. From the economic analysis, there is weak but inconsistent evidence that community engagement interventions are cost-effective. By combining findings across the syntheses, we produced a new conceptual framework.

Limitations

Differences in the populations, intervention approaches and health outcomes made it difficult to pinpoint specific strategies for intervention effectiveness. The syntheses of process and economic evidence were limited by the small (generally not rigorous) evidence base.

Conclusions

Community engagement interventions are effective across a wide range of contexts and using a variety of mechanisms. Public health initiatives should incorporate community engagement into intervention design. Evaluations should place greater emphasis on long-term outcomes, outcomes for indirect beneficiaries, process evaluation, and reporting costs and resources data. The theories of change identified and the newly developed conceptual framework are useful tools for researchers and practitioners. We identified trends in the evidence that could provide useful directions for future intervention design and evaluation.

Personalised risk communication for informed decision making about taking screening tests

BACKGROUND

There is a trend towards greater patient involvement in healthcare decisions. Although screening is usually perceived as good for the health of the population, there are risks associated with the tests involved. Achieving both adequate involvement of consumers and informed decision making are now seen as important goals for screening programmes. Personalised risk estimates have been shown to be effective methods of risk communication.

OBJECTIVES

To assess the effects of personalised risk communication on informed decision making by individuals taking screening tests. We also assess individual components that constitute informed decisions.

SEARCH METHODS

Two authors searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 3, 2012), MEDLINE (OvidSP), EMBASE (OvidSP), CINAHL (EbscoHOST) and PsycINFO (OvidSP) without language restrictions. We searched from 2006 to March 2012. The date ranges for the previous searches were from 1989 to December 2005 for PsycINFO and from 1985 to December 2005 for other databases. For the original version of this review, we also searched CancerLit  and Science Citation Index (March 2001). We also reviewed the reference lists and conducted citation searches of included studies and other systematic reviews in the field, to identify any studies missed during the initial search.

SELECTION CRITERIA

Randomised controlled trials incorporating an intervention with a 'personalised risk communication element' for individuals undergoing screening procedures, and reporting measures of informed decisions and also cognitive, affective, or behavioural outcomes addressing the decision by such individuals, of whether or not to undergo screening.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed each included trial for risk of bias, and extracted data. We extracted data about the nature and setting of interventions, and relevant outcome data. We used standard statistical methods to combine data using RevMan version 5, including analysis according to different levels of detail of personalised risk communication, different conditions for screening, and studies based only on high-risk participants rather than people at 'average' risk. 

MAIN RESULTS

We included 41 studies involving 28,700 people. Nineteen new studies were identified in this update, adding to the 22 studies included in the previous two iterations of the review. Three studies measured informed decision with regard to the uptake of screening following personalised risk communication as a part of their intervention. All of these three studies were at low risk of bias and there was strong evidence that the interventions enhanced informed decision making, although with heterogeneous results. Overall 45.2% (592/1309) of participants who received personalised risk information made informed choices, compared to 20.2% (229/1135) of participants who received generic risk information. The overall odds ratios (ORs) for informed decision were 4.48 (95% confidence interval (CI) 3.62 to 5.53 for fixed effect) and 3.65 (95% CI 2.13 to 6.23 for random effects). Nine studies measured increase in knowledge, using different scales. All of these studies showed an increase in knowledge with personalised risk communication. In three studies the interventions showed a trend towards more accurate risk perception, but the evidence was of poor quality. Four out of six studies reported non-significant changes in anxiety following personalised risk communication to the participants. Overall there was a small non-significant decrease in the anxiety scores. Most studies (32/41) measured the uptake of screening tests following interventions. Our results (OR 1.15 (95% CI 1.02 to 1.29)) constitute low quality evidence, consistent with a small effect, that personalised risk communication in which a risk score was provided (6 studies) or the participants were given their categorised risk (6 studies), increases uptake of screening tests. 

AUTHORS' CONCLUSIONS

There is strong evidence from three trials that personalised risk estimates incorporated within communication interventions for screening programmes enhance informed choices. However the evidence for increasing the uptake of such screening tests with similar interventions is weak, and it is not clear if this increase is associated with informed choices. Studies included a diverse range of screening programmes. Therefore, data from this review do not allow us to draw conclusions about the best interventions to deliver personalised risk communication for enhancing informed decisions. The results are dominated by findings from the topic area of mammography and colorectal cancer. Caution is therefore required in generalising from these results, and particularly for clinical topics other than mammography and colorectal cancer screening.

Improving health promotion to American Indians in the midwest United States: preferred sources of health information and its use for the medical encounter

American Indians and Alaska Natives suffer significant health disparities for many infectious and chronic diseases as compared to the general population. Providing accurate and culturally tailored health information to underserved groups has been shown to influence health behaviors and health outcomes. Little prior research has explored American Indians health information use and preferences. National representative sample surveys such as the Health Information National Trends Survey provide some data on minority groups but are underpowered to provide useful information on American Indians. The present study analyzes data from a survey of over 900 American Indians from the Midwest United States and explores their sources of health information, their preferences for information presentation, and their use of health information prior to and during medical encounters. We conclude that campaigns targeting Natives should be narrowly focused and be community driven or employing community resources. American Indians use a diversity of media sources to obtain health information, with the Internet being underutilized compared to the general population. Partnership with Indian Health Service providers and pharmacists, as well as traditional healers, in the development and dissemination of new health information for Natives may provide the "expert" tone needed to promote health improvements in American Indians.

Can research assessments themselves cause bias in behaviour change trials? A systematic review of evidence from solomon 4-group studies

Background

The possible effects of research assessments on participant behaviour have attracted research interest, especially in studies with behavioural interventions and/or outcomes. Assessments may introduce bias in randomised controlled trials by altering receptivity to intervention in experimental groups and differentially impacting on the behaviour of control groups. In a Solomon 4-group design, participants are randomly allocated to one of four arms: (1) assessed experimental group; (2) unassessed experimental group (3) assessed control group; or (4) unassessed control group. This design provides a test of the internal validity of effect sizes obtained in conventional two-group trials by controlling for the effects of baseline assessment, and assessing interactions between the intervention and baseline assessment. The aim of this systematic review is to evaluate evidence from Solomon 4-group studies with behavioural outcomes that baseline research assessments themselves can introduce bias into trials.

Methodology/Principal Findings

Electronic databases were searched, supplemented by citation searching. Studies were eligible if they reported appropriately analysed results in peer-reviewed journals and used Solomon 4-group designs in non-laboratory settings with behavioural outcome measures and sample sizes of 20 per group or greater. Ten studies from a range of applied areas were included. There was inconsistent evidence of main effects of assessment, sparse evidence of interactions with behavioural interventions, and a lack of convincing data in relation to the research question for this review.

Conclusions/Significance

There were too few high quality completed studies to infer conclusively that biases stemming from baseline research assessments do or do not exist. There is, therefore a need for new rigorous Solomon 4-group studies that are purposively designed to evaluate the potential for research assessments to cause bias in behaviour change trials.

Community-based participatory development, implementation, and evaluation of a cancer screening educational intervention among American Indians in the Northern Plains

The study describes the creation and implementation of a culturally appropriate cancer education intervention, and assesses its efficacy among American Indians in a community with documented cancer-related disparities. Education workshops were developed and conducted on three western South Dakota reservations and in Rapid City by trained community representatives. Over 400 individuals participated in the 2-h workshops. Participants answered demographic questions, questions about previous cancer screening (to establish baseline screening rates), and completed a pre- and post-workshop quiz to assess learning. Participants demonstrated significant increases in cancer screening-related knowledge levels. Surveys reveal that participants found the information of high quality, great value and would recommend the program to friends. Pre-workshop data reveals cancer screening rates well below the national average. Workshop participants increased their knowledge about cancer etiology and screening. This intervention may represent an effective tool for increasing cancer screening utilization among American Indians.

Interventions targeted at women to encourage the uptake of cervical screening

BACKGROUND

World-wide, cervical cancer is the second most common cancer in women. Increasing the uptake of screening, alongside increasing informed choice is of great importance in controlling this disease through prevention and early detection.

OBJECTIVES

To assess the effectiveness of interventions aimed at women, to increase the uptake, including informed uptake, of cervical cancer screening.

SEARCH STRATEGY

We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), Issue 1, 2009. MEDLINE, EMBASE and LILACS databases up to March 2009. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of interventions to increase uptake/informed uptake of cervical cancer screening.

DATA COLLECTION AND ANALYSIS

Two review authors independently abstracted data and assessed risk of bias. Where possible the data were synthesised in a meta-analysis.

MAIN RESULTS

Thirty-eight trials met our inclusion criteria. These trials assessed the effectiveness of invitational and educational interventions, counselling, risk factor assessment and procedural interventions. Heterogeneity between trials limited statistical pooling of data. Overall, however, invitations appear to be effective methods of increasing uptake. In addition, there is limited evidence to support the use of educational materials. Secondary outcomes including cost data were incompletely documented so evidence was limited. Most trials were at moderate risk of bias. Informed uptake of cervical screening was not reported in any trials.

AUTHORS' CONCLUSIONS

There is evidence to support the use of invitation letters to increase the uptake of cervical screening. There is limited evidence to support educational interventions but it is unclear what format is most effective. The majority of the studies are from developed countries and so the relevance to developing countries is unclear.

Interventions that increase use of Pap tests among ethnic minority women: a meta-analysis

OBJECTIVE

Although a variety of intervention methods have been used to promote Pap test screening among ethnic minority women in the US, the effectiveness of such interventions is unclear. We performed a meta-analysis to examine the overall effectiveness of these interventions in increasing Pap test use by ethnic minority women in the US.

METHODS

A search of databases (MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and Science Citation Index-Expanded) and review articles for articles published between 1984 and April 2009 identified 18 randomized and non-randomized controlled trials. The primary study outcome was the difference in the proportion of Pap tests between the treatment and comparison groups.

RESULTS

The pooled mean weighted effect size (d) for the 18 studies was 0.158 (95% confidence interval [CI]=0.100, 0.215), indicating that the interventions were effective in improving Pap test use among ethnic minority women. Among the intervention types, access enhancement yielded the largest effect size (0.253 [95% CI=0.110, 0.397]), followed by community education (0.167 [95% CI=0.057, 0.278]) and individual counseling or letters (0.132 [95% CI=0.069, 0.195]). Combined intervention effects were significant for studies targeting Asian (0.177 [95% CI=0.098, 0.256]) and African American women (0.146 [95% CI=0.028, 0.265]), but not Hispanic women (0.116 [95% CI=-0.008, 0.240]).

CONCLUSIONS

Pap test use among ethnic minority women is most likely to increase when access-enhancing strategies are combined. Further research is needed to determine whether more tightly controlled trials of such interventions might reveal an improved rate of cervical cancer screening in Hispanic women as well.

Examining barriers to cervical cancer screening and treatment in Florida through a socio-ecological lens

Cervical cancer incidence and mortality have declined in the U.S. over the past 50 years because of broad screening efforts; however, some states continue to bear a greater burden due to under-screened and -treated populations. The purpose of this study was to utilize the socio-ecological model to examine barriers to cervical cancer screening and treatment in Florida. A qualitative semi-structured interview guide was used to conduct telephone interviews with 21 purposively sampled health care professionals from 13 high-risk counties. Interviews were transcribed and coded using themes identified a priori based on levels of the socio-ecological model. Investigators identified barriers to cervical cancer screening and treatment in Florida across four levels: (1) regulations and funding issues at the policy level are inconsistent between federal, state and local levels; (2) community level barriers range from cultural differences and fear of deportation, to transportation issues; (3) institutional level barriers complicate the administration of screening and treatment services; and (4) individual beliefs, behaviors, and stressors due to poverty hinder women's ability to access services. Many of our findings are consistent with previous studies that identified constraints to screening and treatment of cervical cancer, such as poverty and lack of access to care. This study adds to the literature by examining barriers from the viewpoint of service providers and program coordinators, and through the utilization of the socio-ecological model to provide a comprehensive framework for identifying and understanding these challenges.

Awareness and knowledge about human papillomavirus among Inuit women in Nunavik, Quebec

Accurate knowledge about human Papillomavirus (HPV) and its link to cervical cancer is essential for women to understand and make use of cervical cancer prevention and detection opportunities. This study was the first to survey awareness and knowledge of HPV in a population of Canadian Inuit. The objectives of this study were to assess the level of awareness and knowledge of Inuit women in Nunavik, Quebec, Canada, about HPV infection and its relation to cervical cancer and to study correlates of this awareness. A cross-sectional survey design was used. Women were recruited through convenience sampling at two recruitment sites in Ungava Bay from March 2008 to June 2009. Questionnaires were completed by 175 women aged 18-63. Thirty one percentage reported that they had heard of HPV. Of the women who had heard of HPV, 53% knew that HPV causes cervical cancer. The level of HPV awareness was not found to vary with participants' age. Awareness of HPV was found to be associated with greater or equal to 13 years of education (OR = 4.4, 95%: 1.3-15.1) and knowing someone with cervical cancer (OR = 3.6, 95%: 1.4-8.9). Despite the high prevalence of HPV and incidence of cervical cancer in Inuit populations, there is a low level of knowledge in this population. The lack of awareness and knowledge and misconceptions found in this study has been consistently found in other non-Indigenous populations.

Healthy Living Partnerships to Prevent Diabetes (HELP PD): design and methods

Although the Diabetes Prevention Program (DPP) developed a lifestyle weight loss intervention that has been demonstrated to prevent type 2 diabetes in high-risk individuals, it has yet to be widely adopted at the community level. The Healthy Living Partnership to Prevent Diabetes study (HELP PD) was designed to translate the DPP approach for use in community settings as a cost-effective intervention led by Community Health Workers (CHW's) and administered through a Diabetes Care Center (DCC). Approximately 300 overweight and obese (BMI 25-40 kg/m(2)) individuals with prediabetes (fasting blood glucose 95-124 mg/dl) were randomly assigned to either a lifestyle weight loss intervention (LW) or an enhanced usual care comparison condition (UC). The goal of LW is >or=7% weight loss achieved through increases in physical activity (180 min/wk) and decreases in caloric intake (approximately 1500 kcal/day). The intervention consists of CHW-led group-mediated cognitive behavioral meetings that occur weekly for 6 months and monthly thereafter for 18 months. UC consists of 2 individual meetings with a registered dietitian and a monthly newsletter. The primary outcome is change in fasting blood glucose. Secondary outcomes include cardiovascular risk factors, health-related quality of life, and social cognitive variables. Outcomes are masked and are collected every 6 months. The cost-effectiveness of the program will also be assessed. A community-based program that is administered through local DCC's and that harnesses the experience of community members (CHW's) may be a promising strategy for the widespread dissemination of interventions effective at preventing type 2 diabetes in high risk individuals.

Faith Moves Mountains: an Appalachian cervical cancer prevention program

OBJECTIVE

To provide a conceptual description of Faith Moves Mountains (FMM), an intervention designed to reduce the disproportionate burden of cervical cancer among Appalachian women.

METHODS

FMM, a community-based participatory research program designed and implemented in collaboration with churches in rural, southeastern Kentucky, aims to increase cervical cancer screening (Pap tests) through a multiphase process of educational programming and lay health counseling.

RESULTS

We provide a conceptual overview to key elements of the intervention, including programmatic development, theoretical basis, intervention approach and implementation, and evaluation procedures.

CONCLUSIONS

After numerous modifications, FMM has recruited and retained over 400 women, 30 churches, and has become a change agent in the community.

Overcoming barriers to cancer care through health navigation programs

OBJECTIVES

To provide an overview of theoretical concepts in community-based, culturally tailored health navigation programs that have improved access to health care for ethnic minority populations, particularly for Asian Americans and Pacific Islanders.

DATA SOURCES

Published articles, reports, book chapters, government documents, research findings.

CONCLUSION

Community-based patient navigation interventions provide promising strategies for providing culturally tailored programs that are more likely to succeed in eliminating cancer disparities in screening and early detection of cancers for diverse cultural communities.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to be more involved in developing and delivering effective, culturally competent community-based cancer screening and treatment navigation programs through education, practice, research, and policy improvement.

Client-directed interventions to increase community demand for breast, cervical, and colorectal cancer screening a systematic review

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 the results of systematic reviews of effectiveness, applicability, economic efficiency, barriers to implementation, and other harms or benefits of interventions designed to increase screening for breast, cervical, and colorectal cancers by increasing community demand for these services. Evidence from these reviews indicates that screening for breast cancer (mammography) and cervical cancer (Pap test) has been effectively increased by use of client reminders, small media, and one-on-one education. Screening for colorectal cancer by fecal occult blood test has been increased effectively by use of client reminders and small media. Additional research is needed to determine whether client incentives, group education, and mass media are effective in increasing use of any of the three screening tests; whether one-on-one education increases screening for colorectal cancer; and whether any demand-enhancing interventions are effective in increasing the use of other colorectal cancer screening procedures (i.e., flexible sigmoidoscopy, colonoscopy, double contrast barium enema). Specific areas for further research are also suggested in this report.

Knowledge and utilization of cervical cancer screening services among Nigerian students

This study assessed the knowledge of cervical cancer, one of the leading causes of cancer deaths in women, and current screening practices among female students at the University of Ibadan, Nigeria. The study was descriptive and cross-sectional. A multi-stage sampling technique was used to select 350 respondents. Semi-structured questionnaires were used. Nearly two-thirds (63%) of respondents have heard about cervical cancer. Knowledge of predisposing factors for the disease was high for early exposure to sex (82%) and sex with multiple partners (70.6%). Only 15.7% knew that abnormal menstrual bleeding is symptomatic of cervical cancer; 14.9% perceived themselves to be susceptible while 2.6% had ever screened for the disease. Though awareness of cervical cancer and its predisposing factors was high, the perception of self-vulnerability and utilization of screening services were extremely low. Intense and integrated educational programs are urgently needed for this group.

A cervical cancer community-based participatory research project in a Native American community

The Messengers for Health on the Apsáalooke Reservation project uses a community-based participatory research (CBPR) approach and lay health advisors (LHAs) to generate knowledge and awareness about cervical cancer prevention among community members in a culturally competent manner. Northern Plains Native Americans, of whom Apsáalooke women are a part, continue to be disproportionately affected by cervical cancer. This article examines quantitative and qualitative changes that occurred in the community since the inception of the Messengers for Health program. Paired sample t tests are used to evaluate the one-group pretest and posttest interviews of 83 Apsáalooke women in knowledge, comfort, and cancer awareness levels. Results reveal cervical cancer knowledge gains, gains in participants' comfort discussing cancer issues, and gains in awareness of cervical cancer and the Messengers program. Field notes, meeting minutes, and community perceptions are used to qualitatively evaluate the effectiveness of the Messengers program. Practice implications are discussed.

Impact of Pretest on Posttest Knowledge Scores With a Solomon Four Research Design

There is a paucity of research on the effects of pretest measurement with prostate cancer screening. What effect does a pretest measurement have on posttest outcomes? This research reports knowledge of prostate cancer screening among men randomized to an Enhanced decision aid versus an Usual Care decision aid. Using a Solomon Four research design, there were a total of 198 men in 4 groups. Most of the sample was African American (78%), with a mean age of 52 years. The greatest posttest knowledge occurred with the Enhanced decision aid in contrast to the Usual Care. The Enhanced/Usual Care groups that had both a pretest and posttest and had received a previous digital rectal examination had the highest means (P = .015), with means of 9.1 and 7.0, respectively. Among men who had a previous digital rectal examination, the greatest increase in score occurred among men randomized to the Enhanced decision aid in contrast to the Usual Care decision aid, 2.9 versus 0.4 (P = .008). The outcome varied based on the status of (1) random group assignment of the Solomon Four design and (2) status of previous digital rectal examination. Implications for nurses include consideration 1 of a pretest to increase posttest knowledge scores.

Community health navigators for breast- and cervical-cancer screening among Cambodian and Laotian women: intervention strategies and relationship-building processes

In recent years, there has been a growing number of programs employing health navigators to assist underserved individuals in overcoming barriers to obtaining regular and quality health care. This article describes the perspectives and experiences of community-based health navigators in the Cambodian and Laotian communities involved in a REACH 2010 project to reduce health disparities in breast and cervical cancer among Pacific Islander and Southeast Asian communities in California. These community health navigators, who have extensive training and knowledge about the cultural, historical, and structural needs and resources of their communities, are well equipped to build trusting relationships with community members traditionally ignored by the mainstream medical system. By comparing the different social support roles and intervention strategies employed by community health navigators in diverse communities, we can better understand how these valuable change agents of the health workforce are effective in improving health access and healthy behaviors for underserved communities.

Factors associated with intentions to adhere to colorectal cancer screening follow-up exams

Background

To increase adherence rate to recommendations for follow-up after abnormal colorectal cancer (CRC) screening results, factors that inhibit and facilitate follow-up must be identified. The purpose of this study was to identify the factors associated with intention to adhere to CRC screening follow-up exams.

Methods

During a 4-week period in October 2003, this survey was conducted with 426 subjects participating in a community-based CRC screening program in Nagano, Japan. Study measures included intention to adhere to recommendation for clinical follow-up in the event of an abnormal fecal occult blood test (FOBT) result, perceived susceptibility and severity of CRC, perceived benefits and barriers related to undergoing follow-up examination, social support, knowledge of CRC risk factors, health status, previous CRC screening, personality and social demographic characteristics. Univariate and multivariate logistic regression analyses on intention to adhere to recommendations for follow-up were performed.

Results

Among the 288 individuals analyzed, approximately 74.7% indicated that they would definitely adhere to recommendations for follow-up. After controlling for age, gender, marital status, education, economic status, trait anxiety, bowel symptoms, family history of CRC, and previous screening FOBT, analyses revealed that lower levels of perceived barriers, higher levers of perceived benefits and knowledge of CRC risk factors were significantly associated with high intention respectively.

Conclusion

The results of this study suggest that future interventions should focus on reducing modifiable barriers by clarifying misperceptions about follow-up, promoting the acceptance of complete diagnostic evaluations, addressing psychological distress, and making follow-up testing more convenient and accessible. Moreover, educating the public regarding the risk factors of CRC and increasing understanding of the benefits of follow-up is also important.

Personalised risk communication for informed decision making about taking screening tests

BACKGROUND

There is a trend towards greater patient involvement in healthcare decisions. Adequate discussion of the risks and benefits associated with different choices is often required if involvement is to be genuine and effective. Achieving both the adequate involvement of consumers and informed decision making are now seen as important goals for any screening programme. Personalised risk estimates have been shown to be effective methods of risk communication in general, but the effectiveness of different strategies has not previously been examined.

OBJECTIVES

To assess the effects of different types of personalised risk communication for consumers making decisions about taking screening tests.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2004), MEDLINE (1985 to December 2005), EMBASE (1985 to December 2005), CINAHL (1985 to December 2005), and PsycINFO (1989 to December 2005). Follow-up searches involved hand searching Preventive Medicine, citation searches on seven authors, and searching reference lists of articles. For the original version of this review (Edwards 2003c) we also searched CancerLit (1985 to 2001) and Science Citation Index Expanded (searched March 2002).

SELECTION CRITERIA

Randomised controlled trials addressing the decision by consumers of whether or not to undergo screening, incorporating an intervention with a 'personalised risk communication element' and reporting cognitive, affective, or behavioural outcomes. A 'personalised risk communication element' is based on the individual's own risk factors for a condition (such as age or family history). It may be calculated from an individual's risk factors using formulae derived from epidemiological data, and presented as an absolute or relative risk or as a risk score, or it may be categorised into, for example, high, medium or low risk groups. It may be less detailed still, involving a listing, for example, of a consumer's risk factors as a focus for discussion and intervention.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed each trial for quality and extracted data. We extracted data about the nature and setting of the intervention, and relevant outcome data, along with items relating to methodological quality. We then used standard statistical methods of the Consumers and Communication Review Group to combine data using MetaView, including analysis according to different levels of detail of personalised risk communication, different condition for screening, and studies based only on high risk participants rather than people at 'average' risk.

MAIN RESULTS

Twenty-two studies were included, nine of which were added in the 2006 update of this review. There was weak evidence, consistent with a small effect, that personalised risk communication (whether written, spoken or visually presented) increases uptake of screening tests (odds ratio (OR) 1.31 (random effects, 95% confidence interval (CI) 0.98 to 1.77). In three studies the interventions showed a trend towards more accurate risk perception (OR 1.65 (95% CI 0.96 to 2.81), and three other trials with heterogenous outcome measures showed improvements in knowledge with personalised risk interventions. There was little other evidence from these studies that the interventions promoted or achieved informed decision making by consumers about participation in screening. More detailed personalised risk communication may be associated with a smaller increase in uptake of tests. That is, for personalised risk communication which used and presented numerical calculations of risk, the OR for test uptake was 0.82 (95% CI 0.65 to 1.03). For risk estimates or calculations which were categorised into high, medium or low strata of risk, the OR was 1.42 (95% CI 1.07 to 1.89). For risk communication that simply listed personal risk factors the OR was 1.42 (95% CI 0.95 to 2.12). Over half of the included studies assessed interventions in the context of mammography. These studies showed similar effects to the overall dataset. The five studies examining risk communication in high risk individuals (individuals at higher risk due to, for example, a family history of breast cancer or other conditions) showed larger odds ratios for uptake of tests than the other studies (random effects OR 1.74; 95% CI 1.05 to 2.88). There were insufficient data from the included studies to report odds ratios on other key outcomes such as: intention to take tests, anxiety, satisfaction with decisions, decisional conflict, knowledge and resource use.

AUTHORS' CONCLUSIONS

Personalised risk communication (as currently implemented in the included studies) may have a small effect on increasing uptake of screening tests, and there is only limited evidence that the interventions have promoted or achieved informed decision making by consumers.

A comparison of two Native American Navigator formats: face-to-face and telephone

The study was designed to test the relative effectiveness of a Navigator intervention delivered face-to-face or by telephone to urban Native American women. The effectiveness of the intervention was evaluated using a design that included a pretest, random assignment to face-to-face or telephone group, and posttest. The Social Cognitive Theory-based intervention was a tailored education program developed to address individual risk factors for breast cancer. At posttest, self-reported mammograms in the past year increased from 29% to 41.3% in the telephone group and from 34.4% to 45.2% in the face-to-face group. There was no difference in change from pretest to posttest between the telephone and face-to-face groups. Navigators can be effective in increasing adherence to recommendations for screening mammography among urban American Indian women.

Development and implementation of a culturally sensitive cervical health survey: a community-based participatory approach

Cervical cancer mortality rates are higher for Great Plains Native American women than for Caucasian women and other Native women. Messengers for Health, a project based on the Apsáalooke (Crow Indian) reservation, utilizes a lay health advisor approach to decrease cervical cancer screening barriers, increase knowledge regarding screening and prevention, and increase the proportion of women receiving Pap tests among Apsáalooke women aged 18 and older. This project utilizes a community-based participatory research model, which emphasizes community member involvement in all phases of the project. The initial phase of this project was the development and implementation of a culturally sensitive survey used to guide the program and benefit the community. The process and preliminary results are presented.

Use of community health workers in research with ethnic minority women

PURPOSE

To explore roles and effectiveness of community health workers in research with ethnic minority women in the United States (US).

METHODS

Medline (1966-2002) and CINAHL (Cumulative Index to Nursing and Allied Health Literature; 1982-2002) databases were used to locate published research studies on the use of community health workers with ethnic minority women in the US. Key words for searches were community health workers, community health aides, health promoters, and community workers.

RESULTS

An integrative analysis of 24 studies showed that, despite varying roles and functions, evidence indicates that community health workers are effective in increasing access to health services, increasing knowledge, and promoting behavior change among ethnic minority women. Other advantages of using community health workers are to provide social support and culturally competent, cost-effective care. Recommendations for future directions of research with community health workers and ethnic minority women include improved conceptualization of the community health worker role, theoretical frameworks for research designs, enhanced methods for evaluating effectiveness, and increased community involvement.

Effects of 2 educational methods on the knowledge, attitude, and practice of women high school teachers in prevention of cervical cancer

Because of the increased emphasis on prevention and early detection of cervical cancer, we studied the effects of 2 educational methods on the knowledge, attitude, and practice, as regards prevention of cervical cancer, of women high school teachers in Tabriz. This study was a semiexperimental research. Samples were 129 female teachers divided in 3 groups: experimental 1 (educated by pamphlets), experimental 2 (educated by a lecture and flash cards), and control group (not manipulated). After doing pretest in the 3 groups, investigators used 2 educational methods for experimental groups. Data regarding the knowledge and attitude of 3 groups were gathered after 14 days and data regarding practice were gathered after 2 months. Chi-square and 1-way ANOVA were used for data analysis. Before education, knowledge, attitude, and practice of the 3 groups were the same, but after education there were significant differences in mean scores of knowledge and attitude of 2 experimental groups as compared with the control group and also between the 2 experimental groups (P < .001). Education by lecture and flash cards was more effective than by pamphlets. In regard to Pap smear practice, there was a significant difference between the 2 experimental groups as compared with the control group (P = .001), but there was no significant difference between the 2 experimental groups. Therefore, educational methods were effective on knowledge, attitude, and practice of teachers regarding prevention of cervical cancer and education by lecture and flash cards was more effective than by pamphlets in increasing knowledge and inducing a positive attitude but the 2 educational methods had the same effect on practice of teachers.

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.

A Large Population-Based Randomized Controlled Trial to Increase Attendance at Screening for Cervical Cancer

Objective: Although cervical cancer is one of the potentially most preventable malignancies, it is still fairly common. In settings with established screening programs, increased compliance is important for future reduction in cervical cancer incidence, but it is presently unclear how this can be effectively achieved. Methods: We conducted a randomized controlled trial including all 12,240 women invited to organized screening in Sweden. To increase compliance, three successive interventions were tested: (a) modified invitation versus the standard invitation letter, (b) reminder letter to nonattenders after the first intervention versus no reminder letter, and (c) phone reminder to nonattenders after the reminder letter versus no phone reminder. We analyzed the proportion of women attending screening after each intervention and the cumulative proportion after the interventions as well as the cumulative proportions of cytologic abnormalities. Results: The modified invitation did not increase attendance compared with the standard invitation letter [difference 1.3% 95% confidence interval (CI) −0.3 to 2.9]. In contrast, a reminder letter increased the proportion of women attending with 9.2% (95% CI 7.9–10.5) compared with women who did not receive a reminder letter, and a phone reminder increased the proportion of women attending with 31.4% (95% CI 26.9–35.9). Combinations of modified invitation, written reminder, and phone reminder almost doubled attendance within 12 months, and the number of detected cytologic abnormalities was more than tripled. Conclusion: Simple reminders by mail and phone can drastically increase women's participation in Papanicolaou smear screening and increase the number of detected precursor lesions and thereby save lives.

Personalised risk communication for informed decision making about entering screening programs

BACKGROUND

There is a trend towards greater patient involvement in health care decisions. Adequate discussion of the risks and benefits associated with different choices is often required if involvement is to be genuine and effective. Achieving adequate involvement of consumers and informed decision making are now seen as important goals for any screening programme. Individualised risk estimates have been shown to be effective methods of risk communication in general, but the effectiveness of different strategies has not previously been examined.

OBJECTIVES

To assess the effects of different types of individualised risk communication for consumers making decisions about participating in screening.

SEARCH STRATEGY

We searched the Cochrane Consumers and Communication Review Group specialised register (searched March 2001), MEDLINE (1985 to 2001), EMBASE (1985 to 2001), CancerLit (1985 to 2001), CINAHL (1985 to 2001), ClinPSYC (1989 to 2001), and the Science Citation Index Expanded (searched March 2002). Follow-up searches involved hand searching Preventive Medicine, citation searches on seven authors, and searching reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials addressing the decision by consumers of whether or not to undergo screening, incorporating an intervention with a 'personalised risk communication element' and reporting cognitive, affective, or behavioural outcomes. A 'personalised risk communication element' is based on the individual's own risk factors for a condition (such as age or family history). It may be calculated from an individual's risk factors using formulae derived from epidemiological data, and presented as an absolute risk or as a risk score, or it may be categorised into, for example, high, medium or low risk groups. It may be less detailed still, involving a listing, for example, of a consumer's risk factors as a focus for discussion and intervention.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed trial quality and extracted data. Data about the nature and setting of the intervention, and the relevant outcome data were extracted, along with items relating to methodological quality.

MAIN RESULTS

Thirteen studies were included. Personalised risk communication (whether written, spoken or visually presented) was associated with increased uptake of screening tests (odds ratio (OR) 1.5 (95% confidence interval (CI) 1.11 to 2.03). There was no evidence from these studies that this increase in uptake of tests was related to informed decision making by consumers. More detailed personalised risk communication was associated with a smaller increase in uptake of tests. That is, for personalised risk communication which used and presented numerical calculations of risk, the OR for test uptake was 1.22 (95% CI 0.56 to 2.68). For risk estimates or calculations which were categorised into high, medium or low strata of risk, the OR was 1.42 (95% CI 1.07 to 1.88). For risk communication that simply listed risk personal risk factors the OR was 1.7 (95% CI 1.17 to 2.48). Most of the included studies addressed mammography programmes. These studies showed slightly smaller effects than the overall dataset, again with numerical calculated risk estimates being associated with lower ORs for uptake of tests (OR 1.13; 95% CI 0.98 to 1.29) than the other categories of (less detailed) personalised risk communication. The four studies examining risk communication in high risk individuals showed larger odds ratios for uptake of tests than the other studies. The OR for numerical calculated risk estimates was 1.48 (95% CI 1.06 to 2.07), compared to 4.66 (95% CI 2.24 to 9.69) for categorised risk estimates and 2.64 (95% CI 1.42 to 4.9) for listed personal risk factors. There were insufficient data from the included studies to report odds ratios on other key outcomes such as: intention to take tests, anxiety, satisfaction with decisions, decisional conflict, knowledge and risk perception.

REVIEWER'S CONCLUSIONS

Personalised risk communication (as currently implemented in the included studies) is associated with increased uptake of screening programmes, but this may not be interpretable as evidence of informed decision making by consumers.

Determinants of participation of women in a cervical cancer visual screening trial in rural south India

The efficacy of a single round of screening of visual inspection with acetic acid (VIA) on cervical cancer incidence and mortality is investigated in a cluster randomized controlled trial in south India. Women aged 30-59 years in 113 clusters in Dindigul District were randomized to VIA screening by nurses (57 clusters, 48,225 eligible women) and to a control group (56 clusters, 30,167 women). 30,577 (63.4%) eligible women participated in screening. Younger, educated, married, multiparous, low-income women and those who have had tubal sterilization had a higher compliance with screening. Of the 2069 women diagnosed with CIN and invasive cancer, 1498 (72.4%) received treatment. Young women, those who practiced contraception and women with high-grade precursor lesions and invasive cancers were more likely to comply with treatment. In summary, our study indicates that women accept screening with VIA by nurses and a moderate level of compliance with screening and treatment can be reached through appropriate service delivery systems including health education activities, personal invitations, clinics in proximity to the target women, and testing and treatment in the same session. Our results imply that integration of screening activities with primary health services seems to have the potential to replicate most of these service delivery conditions in routine programs.

A systematic literature review of the effectiveness of community-based strategies to increase cervical cancer screening

OBJECTIVE

To evaluate and summarize evidence of the effectiveness of interventions available to public health staff that could be used to increase cervical cancer screening to women.

METHOD

A thorough literature review was conducted, articles screened for relevance and assessed for quality.

RESULTS

Of 42 relevant studies, 1 was rated 'strong', 18 'moderate' and 23 'weak'. Among the strong/moderate studies, 10 were aimed at disadvantaged women. The most frequently used intervention was mass media campaigns, alone or combined with individual strategies; followed by individual education using lay health educators; and last, letters of invitation. Thirteen of the moderate/strong studies evaluated strategies that reported statistically significant increases in Pap smear rates and other outcomes.

CONCLUSIONS

Strategies that combined mass media campaigns with direct tailored education to women and/or health care providers seemed most successful. The importance of accurate centralized cytology databases for recall is underscored.

Interventions targeted at women to encourage the uptake of cervical screening

BACKGROUND

Cervical cancer is the third most common cancer world-wide. Increasing the uptake of screening, alongside increasing informed choice is of great importance in controlling this disease through prevention and early detection.

OBJECTIVES

To assess the effectiveness of interventions aimed at increasing uptake, and informed uptake of cervical cancer screening.

SEARCH STRATEGY

Twenty-three electronic databases (to March 2000) were searched with no language restrictions.

SELECTION CRITERIA

Randomised controlled trials (RCTs), or quasi-RCTs of interventions to increase uptake/informed uptake of cervical cancer screening.

DATA COLLECTION AND ANALYSIS

Data on study characteristics and quality were extracted independently by two reviewers. Where data were available, relative risks and 95% CI were calculated and a chi-squared test for heterogeneity was performed.

MAIN RESULTS

Thirty-five studies were included (27 RCTs and eight quasi-RCTs). Heterogeneity between studies limited statistical pooling of data. Overall, however, invitations appear to be effective methods of increasing uptake. In addition, there is limited evidence to support the use of educational materials. The number and quality of included studies limited evidence regarding effectiveness of other interventions. Informed uptake of cervical screening was not considered by any studies.

REVIEWER'S CONCLUSIONS

There was some evidence to support the use of invitation letters to increase the uptake of cervical screening. There was limited evidence to support educational interventions but it was unclear what format was most effective. The majority of the studies were from developed countries and so the relevance to developing countries is unclear.

Community-based cancer screening for underserved women: design and baseline findings from the Breast and Cervical Cancer Intervention Study

BACKGROUND

Underutilization of breast and cervical cancer screening has been observed in many ethnic groups and underserved populations. Effective community-based interventions are needed to eliminate disparities in screening rates and thus to improve prospects for survival.

METHODS

The Breast and Cervical Cancer Intervention Study was a controlled trial of three interventions in the San Francisco Bay Area from 1993 to 1996: (1) community-based lay health worker outreach; (2) clinic-based provider training and reminder system; and (3) patient navigator for follow-up of abnormal screening results. Study design and a description of the interventions are reported along with baseline results of a household survey conducted in four languages among 1599 women, aged 40-75.

RESULTS

Seventy-six percent of women ages 40 and over had had at least one mammogram, and most had had a clinical breast examination (88%) and Pap smear (89%). Rates were significantly lower for non-English-speaking Latinas and Chinese women (56 and 32%, respectively, for mammography), and maintenance screening (three mammograms in the past 5 years) varied from 7% (non-English-speaking Chinese) to 53% (Blacks). Pap smear screening in the past 3 years was low among non-English-speaking Latinas (72%) and markedly lower among non-English-speaking Chinese women (24%). The strongest predictors of screening behavior were having private health insurance and frequent use of medical services. Having a regular clinic and speaking English were also important. Race/ethnicity, education, household income, and employment status were, overall, not significant predictors of screening behavior.

CONCLUSIONS

These baseline results support the importance of cancer screening interventions targeted to persons of foreign origin, particularly those less acculturated.

Comparison of clinical outcome in black and white women treated with radiotherapy for cervical carcinoma

BACKGROUND

The purpose of this investigation was to evaluate the significance of race on the cancer-specific survival outcome of women treated with radiotherapy for advanced-stage cancer of the uterine cervix.

METHODS

Data from 922 women with cancer of the uterine cervix treated with radiotherapy were reviewed. Patients were treated at the Mallinckrodt Institute of Radiology from 1959 through 1993. There were 576 women with clinical Stage II cancer and 346 women with clinical Stage III cancer. All women were treated following standard medical care treatment policies according to the stage of their disease. Data were analyzed by race and known treatment-related prognostic factors. Overall and cancer-specific survivals were evaluated.

RESULTS

The 5-year cancer-specific survivals for clinical Stage II were 66 and 61% (P = 0.56) for white and black women, respectively. The corresponding 5-year overall survivals were 60 and 51% (P = 0.02). The 5-year cancer-specific survivals for clinical Stage III were 38 and 47% (P = 0.34) for white and black women, respectively. The associated 5-year overall survivals were 32 and 40% (P = 0.37). No differences in treatment-related factors were identified.

CONCLUSIONS

In a cancer treatment system where black and white women with clinical Stage II and III cancer of the uterine cervix are all treated with radiotherapy alone, following standard treatment policies, no significant difference in cancer-specific survival outcome is shown. Multivariate analysis revealed that clinical stage and overall treatment time are significant variables affecting the control of tumor by radiotherapy. Overall survivals for the two racial groups are different and may be related to other non-cancer-related factors.

Impact of a culturally appropriate intervention on breast and cervical screening among native Hawaiian women

BACKGROUND

Native Hawaiian women have the highest breast and cervical cancer mortality rates and lowest screening rates in Hawai'i. This paper summarizes impacts of a breast and cervical cancer screening intervention spearheaded by a Native Hawaiian community.

METHODS

Six hundred seventy-eight randomly selected Native Hawaiian women completed two telephone surveys assessing their cancer screening behaviors: 318 women from a community that implemented an intervention, known as a Kokua Group, to provide culturally tailored education and support in a group setting and 360 women from communities without this intervention. The surveys were conducted before intervention implementation and 3 years later, 4 to 5 months after the last intervention session.

RESULTS

At posttest, intervention community women reported positive changes in 4 of 12 screening activities (P < or = 0.05), while no changes were found among controls. Some women in both communities had heard about and/or participated in Kokua Groups. Hierarchical logistic regression showed that controlling for community, demographics, and pretest scores, Kokua Group knowledge or participation was a significant predictor (P < 0.05) of 9 of 12 screening-related behaviors.

CONCLUSIONS

Positive changes in screening activities among women aware of the intervention support the importance of information diffusion by community consumers. Diffusion may occur beyond the boundaries of the community as defined.

Cervical cancer screening in developing countries: why is it ineffective? The case of Mexico

BACKGROUND

Mexico established a national cervical cancer-screening program in 1974. Despite the implementation of the program, there was a steady mortality trend of 16 per 100,000 women over 15 years.

METHODS

A diagnostic procedure of the pitfalls was applied to the following steps of the screening procedure: Pap sampling quality; cytological diagnosis validity; compliance of women; and determinants of non-participation.

RESULTS

The low effectiveness of screening on cervical cancer is principally due to factors associated with quality and coverage. Pap quality is deficient; 64% of a random sample of specimens lacked endocervical cells. Reading centers presented false negative indices of between 10 and 54%. Women seek screening in a late stage of disease (55% with cervical cancer seek care because they have symptoms). In addition, coverage is low; in women between 15 and 49 years of age in Mexico City, 64.2% have a history of Pap, compared with 30% in rural areas. Knowledge of what the Pap is used for strongly determines the use of screening. In rural areas, only 40% of women are informed about the purpose of the Pap test.

CONCLUSIONS

A proposal to reorganize Mexico's screening program includes the following five main strategies: (a) increased coverage; (b) improved quality control of how cervical smears are taken; (c) better interpretation of Pap tests; (d) guaranteed treatment for those whose tests show abnormalities, and (e) improved follow-up.

Proposal to institutionalize criteria and quality standards for cervical cancer screening within a health care system

The uterine cervix is the most common cancer site for females. Approximately 52,000 new cases occur annually in Latin America, thus the need to improve efficiency and effectiveness of Cervical Cancer Screening Programs (CCSP) is mandatory to decrease the unnecessary suffering women must bear. This paper is addressing essential issues to revamp the CCSP as proposed by the Mexican official norm. A general framework for institutionalizing CCSP is outlined. Furthermore, strategies to strengthen CCSP performance through managerial strategies and quality assurance activities are described. The focus is on the following activities: 1) improving coverage; 2) implementing smear-taking quality control; 3) improving quality in interpretation of Pap test; 4) guaranteeing treatment for women for whom abnormalities are detected; 5) improving follow-up; 6) development of quality control measures and 7) development of monitoring and epidemiological surveillance information systems. Changes within the screening on cervical cancer may be advocated as new technologies present themselves and shortcomings in the existing program appear. It is crucial that these changes should be measured through careful evaluation in order to tally up potential benefits.

The quality of Pap test specimens collected by nurses in a breast and cervical cancer screening clinic

BACKGROUND

It is possible that nurses can help close the gap between the Healthy People 2000 clinical preventive services goals and current cancer screening rates by collecting Pap test specimens in clinical practices. The purpose of this analysis was to determine whether nurses can collect high-quality Pap tests.

DESIGN

Retrospective cohort analysis of all Pap tests submitted to a commercial pathology laboratory between January 1, 1996 and July 31, 1996. Pap tests collected by the nurses at Rosebud Hospital (N = 404) were compared to the Pap tests collected by other providers at the Rosebud Hospital (N = 118) and the Pap tests collected by providers from all other sites (N = 22,696).

SETTING

The Indian Health Service Hospital, Rosebud, South Dakota.

SUBJECTS

Eight nurses who had been trained to collect Pap test specimens.

MAIN OUTCOME MEASURES

The proportion of Pap test specimens that were wholly satisfactory and the proportion of Pap test specimens collected from nonpregnant patients that lacked endocervical cells.

RESULTS

The proportion of specimens that were wholly satisfactory was 79.8% (95% CI = 75.9-83.7) for the nurses, 65.3% (95% CI = 56.7-73.9) for other Rosebud providers, and 81.7% (95% CI = 81.2-82.2) for non-Rosebud providers. The proportion of specimens that lacked endocervical cells and were from nonpregnant patients was 6.4% (95% CI = 4.0-8.8) for Rosebud nurses, 8.5% for other Rosebud providers (95% CI = 3.5-13.5), and 7.9% for non-Rosebud providers (95% CI = 7.6-8.2).

CONCLUSIONS

After one week of training, nurses can collect Pap test specimens that are of the same quality as the specimens collected by physicians, nurse practitioners, and physician assistants. The widespread availability of female nurses and the high quality of their work suggest that they can contribute to the Healthy People 2000 goals by collecting Pap test specimens.

A review of cervical cancer screening intervention research: implications for public health programs and future research

In this paper we review the published literature with respect to cervical cancer screening intervention research. Mass media campaigns appear to work best in promoting cervical cancer screening when multiple media are used, when they promote specific screening programs that eliminate or reduce access barriers, or when they are used in combination with other strategies. Many positive examples of using outreach staff to promote cervical cancer screening, as well as using mobile examination rooms in the community, were found. Substantial evidence that letters mailed to patient populations are efficacious was found, especially in promoting interval screening; however, bulk mailings to nonpatient populations have generally not been successful. Both physician and patient prompts have shown promise as well as opportunistic screenings in both the outpatient and the inpatient settings. In addition, several strategies for reducing loss to follow-up among women with abnormal test results were identified, including telephone follow-up, educational mailouts, audiovisual programs, clinic-based educational presentations and workshops, transportation incentives, and economic vouchers. Of special note is the success of other countries in establishing centralized recall systems to promote interval screening for cervical cancer. Ultimately, such systems could replace the need for opportunistic screening in underserved populations and perhaps many community outreach efforts. It is argued that health departments represent a logical starting point for developing a network of recall systems in the United States for underserved women.
