The simultaneous analysis of patient, physician and group practice influences on annual mammography performance

The company you keep: health behavior among work peers

There is widespread agreement that behavior crucially influences one's health. However, little is known about what actually determines health-related behavior. We explore the impact of the place where many people spend most of their time, at work, and analyze whether an individual's decision to participate in health screening is related to the observed behavior of peers at work. We use linked employer-employee data and exploit the transitions of workers to new jobs. We find that the health behavior of co-workers highly correlated. A comparison of individuals moving into new firms shows that participation in general health checks, mammography screening, and prostate-specific antigen tests increases with the share of work peers attending these screenings. To differentiate between peer effects and common influences at the workplace, we further separate the peer groups within firms and show that workers with similar characteristics tend to have a stronger effect on individual screening participation.

Barriers to Breast Cancer Screening among Diverse Cultural Groups in Melbourne, Australia

This study explored the association between health literacy, barriers to breast cancer screening, and breast screening participation for women from culturally and linguistically diverse (CALD) backgrounds. English-, Arabic- and Italian-speaking women (n = 317) between the ages of 50 to 74 in North West Melbourne, Australia were recruited to complete a survey exploring health literacy, barriers to breast cancer screening, and self-reported screening participation. A total of 219 women (69%) reported having a breast screen within the past two years. Results revealed that health literacy was not associated with screening participation. Instead, emotional barriers were a significant factor in the self-reported uptake of screening. Three health literacy domains were related to lower emotional breast screening barriers, feeling understood and supported by healthcare providers, social support for health and understanding health information well enough to know what to do. Compared with English- and Italian-speaking women, Arabic-speaking women reported more emotional barriers to screening and greater challenges in understanding health information well enough to know what to do. Interventions that can improve breast screening participation rates should aim to reduce emotional barriers to breast screening, particularly for Arabic-speaking women.

The Importance of Family History in Breast Cancer Patients in Primary Care Setting: a Cross-sectional Study

Screening recommendations of physicians are important for women to raise awareness about their risk factors and to promote appropriate screening behaviors. However, it seems challenging for primary care physicians (PCPs) to balance disease prevention and diagnosis, treatment. The objective of this study was to describe physicians' breast cancer consultancy practice including family history, cancer prevention issues for the women they care. This cross-sectional study included 577 women aged above 45 years, free of breast cancer, during their visits to their PCPs. Nearly half of the women reported their visit to PCPs for an annual examination during the year. Among them, 36.1% had first-degree relatives with cancer and 7.3% with breast cancer. But they reported to be asked about family history of cancer and informed about cancer prevention issues 35.1 and 26.4%, respectively. Cancer still seems to be a hard issue to be discussed, even with women visiting PCPs for annual examination. Asking first-degree relative with breast cancer can give PCPs the chance of determining women with increased risk and support women's appropriate understanding of their own risk in relation to their family history. This routine can make shared-decision making for developing person-centered approach for breast cancer screening possible. Further studies are needed for better understanding of loss of consultancy leadership of physicians for breast cancer.

Cognitive biases and heuristics in medical decision making: a critical review using a systematic search strategy

BACKGROUND

The role of cognitive biases and heuristics in medical decision making is of growing interest. The purpose of this study was to determine whether studies on cognitive biases and heuristics in medical decision making are based on actual or hypothetical decisions and are conducted with populations that are representative of those who typically make the medical decision; to categorize the types of cognitive biases and heuristics found and whether they are found in patients or in medical personnel; and to critically review the studies based on standard methodological quality criteria.

METHOD

Data sources were original, peer-reviewed, empirical studies on cognitive biases and heuristics in medical decision making found in Ovid Medline, PsycINFO, and the CINAHL databases published in 1980-2013. Predefined exclusion criteria were used to identify 213 studies. During data extraction, information was collected on type of bias or heuristic studied, respondent population, decision type, study type (actual or hypothetical), study method, and study conclusion.

RESULTS

Of the 213 studies analyzed, 164 (77%) were based on hypothetical vignettes, and 175 (82%) were conducted with representative populations. Nineteen types of cognitive biases and heuristics were found. Only 34% of studies (n = 73) investigated medical personnel, and 68% (n = 145) confirmed the presence of a bias or heuristic. Each methodological quality criterion was satisfied by more than 50% of the studies, except for sample size and validated instruments/questions. Limitations are that existing terms were used to inform search terms, and study inclusion criteria focused strictly on decision making.

CONCLUSIONS

Most of the studies on biases and heuristics in medical decision making are based on hypothetical vignettes, raising concerns about applicability of these findings to actual decision making. Biases and heuristics have been underinvestigated in medical personnel compared with patients.

Psychosocial determinants of socioeconomic inequalities in cancer screening participation: a conceptual framework

Cancer screening participation shows a strong, graded association with socioeconomic status (SES) not only in countries such as the United States, where insurance status can be a barrier for lower income groups, but also in the United Kingdom, where the National Health Service provides all health care to residents, including screening, for free. Traditionally, the literature on socioeconomic inequalities has focused on upstream factors, but more proximal (downstream) influences on screening participation also need to be examined, particularly those that address the graded nature of the association rather than focusing specifically on underserved groups. This review offers a framework that links some of the components and corollaries of SES (life stress, educational opportunities, illness experience) to known psychosocial determinants of screening uptake (beliefs about the value of early detection, fatalistic beliefs about cancer, self-efficacy). The aim is to explain why individuals from lower SES backgrounds perceive cancer screening tests as more threatening, more difficult to accomplish, and less beneficial. A better understanding of the mechanisms through which lower SES causes negative attitudes toward screening could facilitate the development of intervention strategies to reduce screening inequalities.

Factors associated with breast cancer screening in Asian Indian women in metro-Detroit

Few studies have examined social factors related to breast cancer screening in Asian Indian women in the Midwestern US. This cross-sectional, community-based survey utilized constructs of the Health Belief Model to examine factors associated with breast cancer screening among Asian Indian women in metropolitan Detroit, Michigan. Of the 160 participants, 63.8% reported receiving both a clinical breast exam and mammogram within the past 2 years. Women were more likely to screen for breast cancer if they had a college education, lived in the US for more years, perceived that breast cancer screening is useful in detecting breast cancer early, agreed that mammography was important, and received a recommendation by a healthcare provider to get a mammogram. These findings highlight the need for further research on regional differences in breast cancer screening knowledge, behaviors and predictors among Asian Pacific Islanders subgroups such as Asian Indian women who recently immigrated to the US.

Primary care physicians' assessments of older patients' health and psychological status and recommendation of mammography

BACKGROUND

Recommendation of mammography may be particularly important for older women; nevertheless, physicians are less likely to recommend mammography to older women. Our objective was to examine the characteristics of older patients for whom primary care physicians recommend mammography.

METHODS

Two hundred sixteen women aged 65 to 80 years were screened for depressive symptoms in primary care offices and invited to participate. They then completed a baseline in-home assessment between 2001 and 2003. At the time of the baseline in-home assessment, mammogram use and psychological status were assessed with commonly used and validated standard questionnaires. At the time of the index visit, physicians were asked to provide assessments of the patients.

RESULTS

Patient-reported physician recommendation of mammography was more likely among patients the physicians rated as anxious than among patients the physicians rated as not being anxious (unadjusted odds ratio, 2.08; 95% confidence interval, 1.10-3.94). In multivariate models that controlled for physician ratings of knowledge of the patient, the association between physician rating of anxiety with patient-reported physician recommendation of mammography remained significant. Patient-reported physician recommendation of mammography was not significantly more likely among patients the physicians rated as depressed than among patients the physicians rated as not being depressed (unadjusted odds ratio, 1.57; 95% confidence interval, 0.86-2.85).

CONCLUSIONS

Identification of anxiety may influence the recommendation of mammography among primary care physicians. An understanding of factors that influence the recommendation of mammography by primary care physicians may have important implications for interventions to improve rates of mammography use among older women.

Impact of women's experiences during mammography on adherence to rescreening (United States)

OBJECTIVE

To examine the relationship between womens' experiences during mammography and their likelihood of being rescreened after receiving a negative or benign mammogram.

METHODS

Telephone interview and medical record data were collected from a random sample of enrollees from four states in a national screening program targeting uninsured and underinsured women at least 30 months after they had undergone an index mammogram in 1997. We calculated 30-month rescreening rates by prior mammography characteristics including pain and embarrassment, worry, convenience of appointment time, treatment by staff, and financial considerations.

RESULTS

Of the 2,000 women in the sampling frame, 1,895 (93.6%) were located, 1,685 (88.6%) were interviewed and 1,680 provided data required for our analysis. Overall, 81.5% of the women had undergone rescreening. More than 90% of the women reported being 'satisfied' or 'very satisfied' with treatment by facility staff, facility location and wait time during the appointment. Statistically significant decreased rescreening rates were seen for women who reported feeling embarrassed and for women reporting dissatisfaction with ability to schedule a convenient appointment time.

CONCLUSION

These results suggest that providing additional reassurance and privacy may increase rescreening rates.

Time spent in the united states and breast cancer screening behaviors among ethnically diverse immigrant women: Evidence for acculturation?

The current study was designed to investigate the relations between time spent in the United States and breast cancer screening in a large sample (N=915) of ethnically diverse immigrant women living in New York City. Previous research among Hispanic women has suggested that acculturation positively influences health beliefs and preventive health behaviors. However, research has not yet extended to other growing immigrant groups, including women from Haiti and the English-speaking Caribbean, and has not tested whether time spent in the United States differentially impacts breast screening across groups that are known to vary in their health beliefs. As expected, time spent in the United States was associated with a greater number of mammograms and clinical breast exams. Importantly, these relations held even when controlling for (a) age, income, education, marital status; (b) morbidity, health insurance, physician's recommendation, physical exams; and (c) ethnicity. Moreover, time spent in the United States interacted with being Haitian to predict the number of clinical breast exams. Even though Haitians were less likely to utilize breast cancer screening overall, time spent in the United States had a stronger effect on the number of clinical breast exams for Haitian women. Results are discussed in terms of the ethnic-specificity of health beliefs, how they may change over time and their implications for preventive health behaviors.

Loss-framed minimal intervention increases mammography use

INTRODUCTION

Although mammography is the most effective early detection breast cancer screening technology available, it is underutilized. This study was conducted to test the effectiveness of a loss-framed minimal intervention to increase mammography use. Loss-frame refers to a communication strategy in which messages are framed from the perspective of what a person has to lose by not taking a particular behavioral action.

METHODS

Participants were medically un- and underinsured women 50-64 years old who called one of two urban clinics randomly selected based on demographic statistical equivalency. The women who participated telephoned to inquire about a mammogram during the 6-month study period. The group randomly designated as the experimental group received a loss-framed message conveyed by trained staff telephonically. Members of the comparison group received the "usual" communication, also conveyed telephonically. In the experimental group, 31 of 112 (27%) women who inquired received mammograms, whereas 157 of the 992 (16%) comparison group women who inquired received mammograms.

RESULTS

The odds of a mammogram, adjusted for race and breast cancer symptoms, significantly increased for the experimental (odds ratio [OR] = 1.914, chi2 = 7.48, p = .0063, 95% confidence interval [CI] 1.20-3.05) versus comparison group.

CONCLUSIONS

A loss-framed, in-reach, minimal intervention approach holds promise as a mammography promotion strategy.

Patients' interest in discussing cancer risk and risk management with primary care physicians

Little is known about patients' preferences for discussing cancer risks and risk management with primary care physicians. We sought to determine whether patients want to discuss such topics and what factors are associated with this interest. Participants (375 patients ages 40-85, of diverse race and education level) completed a telephone survey prior to scheduled physician visits. Survey included items on perceived health, perceived cancer risk, education level, and whether participants would like to discuss with a physician their breast, ovarian or colon cancer risk, tamoxifen, cancer genetic counseling, and colon cancer screening. Greater proportions were interested in discussing risks for each cancer, compared with those who were not (P < 0.0001). More participants were interested in discussing mammograms (80%) and cancer genetic counseling (60%) than tamoxifen (49%) or colon cancer screening modalities (43-53%). For many topics, poorer perceived health was associated with greater interest in future discussion; higher education level was associated with less interest.

Fear, Anxiety, Worry, and Breast Cancer Screening Behavior: A Critical Review

Anxiety, fear, and worry are variously described as facilitators and barriers of breast cancer screening. However, several contradictions are evident in this research. A review article described the literature regarding the relations among fear, anxiety, and worry, along with emotion regulatory styles, and breast cancer screening behaviors before critiquing it in an attempt to uncover preliminary explanations for these discrepancies. Three main conclusions are drawn. First, it is suggested that researchers need to clearly define the components of cancer and the screening process that women are afraid of as each may bear a different relation to screening behavior. Second, greater care needs to be taken to employ psychometrically valid and reliable measures of fear and anxiety. Third, studies need to more systematically test findings across the minority and ethnic groups at greatest risk. A framework is presented and suggestions regarding the continued development of this promising area of research are made.

Implementing evidence-based practice: evaluation of an opinion leader strategy to improve breast-feeding rates

OBJECTIVE

The objective was to evaluate the effectiveness of opinion leaders in raising breast-feeding rates.

STUDY DESIGN

A randomized controlled trial of an opinion leader strategy in 18 hospitals in Central New York State compared mothers' intention to breast-feed during baseline and study years. Multivariate logistic regression with a mixed model analyzed the effects on breast-feeding exclusively and on breast- and formula-feeding combined.

RESULTS

Obstetric clinicians had a high degree of knowledge about breast-feeding benefits and of perceived responsibility to recommend breast-feeding. Obstetricians, family practitioners, and midwives agreed on the person identified as the opinion leader, in each case an obstetrician who was chief of obstetrics or obstetrics-gynecology. Breast-feeding rates in hospitals with the opinion leader intervention did not differ significantly from those in control-group hospitals during the study year.

CONCLUSION

The opinion leader strategy in this case did not improve breast-feeding rates during the study year. Opinion leader strategies may make assumptions about clinician control that are not justified in situations such as breast-feeding.

Diversity matters: Unique populations of women and breast cancer screening

BACKGROUND

Ethnic differences in breast cancer screening behaviors are well established. However, there is a lack of understanding regarding exactly what causes these differences and which characteristics in low-screening populations should be targeted in an effort to modify screening behavior.

METHODS

Stratified cluster sampling was used to recruit 1364 women (ages 50-70 years) from 6 ethnic groups: African-American women; U.S.-born white women; English-speaking Caribbean, Haitian, and Dominican women; and immigrant Eastern-European women. In interviews, respondents provided information concerning demographic and structural variables related to mammogram utilization (age, education, income, marital status, physician recommendation, access, and insurance) and a set of cognitive variables (fatalism, perception of personal risk, health beliefs concerning cancer) and socioemotional variables (stress, cancer worry, embarrassment, and pain).

RESULTS

For data analysis, the authors used a 2-step logistic regression with frequency of mammograms over a 10-year period (< or = 4 mammograms over 10 years or > or = 5 mammograms over 10 years) as a dependent variable. U.S.-born African-American women and Dominican women were screened as frequently as European-American women, but the remaining minority groups were screened with less frequency. With one exception, ethnicity ceased to predict screening frequency once cognitive and emotional variables were controlled.

CONCLUSIONS

Although women from clearly operationalized ethnic groups continue to screen at rates substantially below those of the majority groups, these differences appear to be explained substantially by differences in psychologic variables. This is encouraging because, rather than targeting culture for intervention, variables can be targeted that are amenable to change, such as emotions and beliefs.

Factors affecting the intention of providers to deliver more effective continuing medical education to general practitioners: a pilot study

BACKGROUND

Despite the importance of continuing medical education (CME) for GPs, there has been little research into how providers decide what types of CME to deliver to GPs. This study aimed to identify factors affecting the intention of providers to provide more effective types of CME; and to design a survey instrument which can be used to test the applicability of Triandis' model of social behaviour to the provision of CME to general practitioners.

METHODS

This was a cross-sectional study on a convenience sample of 11 Australian providers of CME for interviews and a random sample of 25 providers for the pilot test. Open-ended interviews structured on Triandis' theory were performed with key informants who provide CME to GPs. These were used to develop a pilot survey instrument to measure the factors affecting intention, resulting in a revised instrument for use in further research.

RESULTS

There was a broad range of factors affecting providers' intention to deliver more effective forms of CME identified, and these were classifiable in a manner which was consistent with Triandis' model. Key factors affecting providers' intention were the attitude toward CME within organisations and the time and extra work involved.

CONCLUSIONS

We identified a range of potential factors influencing the intention of providers to provide more effective forms of CME, in all categories of Triandis model. Those interested in increasing the choice of more effective CME activities available to GPs may need to broaden the methods used in working with providers to influence them to use more effective CME techniques. The interview material and questionnaire analysis of the pilot survey support the use of Triandis model. Further research is needed to validate Triandis'model for the intention to deliver more effective forms of CME. Such research will inform future strategies aimed at increasing the amount and choice of effective CME activities available for GPs.

Psychosocial Variables, External Barriers, and Stage of Mammography Adoption

Guided by H. Triandis's (1980) theory of behavior and the transtheoretical model, the study purpose was to examine differences in psychosocial variables and external conditions by stage of mammography adoption. Sampled from a statewide population, participants (N=509) were women aged 51-80. They had been contacted by telephone, screened for eligibility (e.g., no history of cancer or recent mammogram), and interviewed 3-6 months later. Higher utility beliefs, social influences, and practitioner interactions about mammography were associated with improved stage of adoption, as were lower negative affect and external barriers regarding mammography. Higher decisional balance scores, with and without negative affect toward mammography were associated with improved stage. Controlling for variables reflecting pros and cons, negative affect toward mammography further distinguished among stages. A richer set of pros and cons measures could explain screening more fully.

Provider characteristics and mammography recommendation among women in their 40s and 50s

OBJECTIVES

Healthcare provider recommendation for mammography is one of the strongest predictors of women's mammography use, but few studies have examined the association of provider characteristics with mammography recommendations. We examined the relationship of provider gender, age, medical specialty, and duration of relationship with the patient to report mammography recommendation.

METHODS

Participants were women ages 40-45 and 50-55 who were part of a larger intervention study of decision making about mammography. We examined the relationship of provider characteristics to patient-reported mammography recommendations at baseline and at 24-month follow-up.

RESULTS

At baseline, 74% of women in their 40s and 79% of women in their 50s reported provider mammography recommendations within the prior 2 years. Proportions were similar at the 24-month follow-up. In multivariate logistic regression models including both patient and provider characteristics, women in their 40s who had female providers were more likely to report mammography recommendations than those with male providers at baseline (OR=1.83, p=0.01) and follow-up (OR=1.74, p=0.03). Among women in their 50s, participants whose regular providers were primary care physicians were more likely to report recommendations at baseline than those whose regular providers were obstetrician/gynecologists (OR=1.68, p=0.03).

CONCLUSIONS

About one fourth of women in this study reported not having been advised by a healthcare provider to have a mammogram. All women in the study had health insurance. Among women in their 40s, for whom mammography guidelines were controversial at the time of data collection, provider gender was an important predictor of patient-reported mammography recommendation.

Prediction of intern attendance at a seminar-based training programme: a behavioural intention model

CONTEXT

The factors determining intern attendance at 'resident rounds' training programmes are not known.

AIMS

This study aimed to use a behavioural model (the Triandis theory of social behaviour) to predict intern attendance at the resident round programme at a metropolitan teaching hospital.

SUBJECTS

These included 109 interns in a large metropolitan teaching hospital, in the 1996 and 1997 cohorts.

METHODS

Tabulated responses from a structured interview administered to 10 randomly selected interns were used to develop survey items related to the Triandis variables. Attendance was monitored using a sessional logbook and by self-report. Item analysis was conducted for each variable scale. Stepwise multiple regression models were constructed to predict attendance and intention.

RESULTS

The average proportion of resident rounds attended was 43% (95% confidence intervals (CI) 40-47%) from logbook attendance, and 63% (95% CI 61-65%) by self-report. Cronbach's alpha for the subscales ranged from 0.62 to 0.91. Intern attendance was predicted by the habit of attendance and negatively predicted by facilitating conditions (AdjR2=0.26, P<0.0001). The intention to attend was only independently predicted by perceived consequences (AdjR2= 0.19, P < 0.0001).

CONCLUSIONS

The establishment of resident education programmes within teaching hospitals requires attention to and modification of facilitating conditions that may allow improvements in attendance and in quality of the programme.

The role of physician recommendation in women's mammography use: is it a 2-stage process?

OBJECTIVE

To explore the use of a 2-stage model in explaining the role of physician recommendation in women's use of mammography screening and to provide an integrated framework for understanding the mammography-use process.

METHODS

Data on 1,301 women aged > or =52 years from the North Carolina Breast Cancer Screening Program (NC-BCSP) questionnaire were combined with information from 91 of their physicians from the North Carolina Medical Board. A 2-stage system of equations using women's characteristics (demographic, health, access), physicians' characteristics (demographic, practice), women's beliefs, and women's report of a physician recommendation was created and statistically tested. The model was estimated using 2-stage logistic and probit estimation.

RESULTS

The 2-stage approach produced different results compared with the single pooled model. In the second-stage mammography-use model, younger age, family history of breast cancer, and a woman's having ever requested a mammogram retained significance (P < or = 0.05) in addition to the predicted value of physician recommendation obtained from the first stage. Women's characteristics significantly associated with physician recommendation in the first stage included some access, health risk, and demographic variables as well as physician age and race (P < or = 0.05).

CONCLUSIONS

A 2-stage model for estimating mammography use among women with regular physicians may be more informative than a single model. These results imply that programs designed to increase mammography rates should focus on ensuring appropriate physician recommendations in addition to encouraging women to request screening. Future research should consider using an integrated framework for evaluating utilization of mammography and other preventive services.

The relationship between social network characteristics and breast cancer screening practices among employed women

This study examined the relationship between social network characteristics and breast cancer screening practices among employed women. We hypothesized that larger social networks, higher levels of support from networks, and stronger social influences to undergo screening would be positively associated with regular utilization of mammograms and clinical breast examinations. Data were collected from women aged 52 and over who were employed in 27 worksites (N = 1,045). Social network characteristics, breast cancer screening practices, and sociodemographic factors were assessed in a self-administered survey. Bivariate analyses revealed that social influences were significantly associated with regular screening; social support was only marginally associated with regular screening; and social network size was not at all associated. In multivariate analyses, only the perception that screening is normative among one's peers was predictive of regular screening. Provider recommendation was the single most potent predictor of regular screening. These findings provide support for the importance of social norms in motivating women to adhere to screening guidelines. In addition, they underscore the potent impact of provider recommendations on women's screening practices.

Breast and cervical cancer screening among women with physical disabilities

OBJECTIVE

This article reports findings from the National Study of Women with Physical Disabilities about rates of screening for breast and cervical cancer and factors associated with regular screening in a large sample of women with a variety of physical disabilities and a comparison group of women without disabilities.

DESIGN

Case-comparison study using written survey. Data were analyzed using measures of central tendency, chi 2 analysis, logistic regression, and risk using odds ratios.

SETTING

General community.

PARTICIPANTS

A total of 843 women, 450 with disabilities and 393 of their able-bodied friends, aged 18 to 65, who completed the written questionnaire. The most common primary disability type was spinal cord injury (26%), followed by polio (18%), neuromuscular disorders (12%), cerebral palsy (10%), multiple sclerosis (10%), and joint and connective tissue disorders (8%). Twenty-two percent had severe functional limitations, 52% had moderate disabilities, and 26% had mild disabilities.

MAIN OUTCOME MEASURES

Outcomes were measured in terms of frequency of pelvic exams and mammograms.

RESULTS

Women with disabilities tend to be less likely than women without disabilities to receive pelvic exams on a regular basis, and women with more severe functional limitations are significantly less likely to do so. No significant difference was found between women with and without disabilities, regardless of severity of functional limitation, in receiving mammograms within the past 2 years. Perceived control emerged as a significant enhancement factor for mammograms and marginally for pelvic exams. Severity of disability was a significant risk factor for noncompliance with recommended pelvic exams, but not mammograms. Race was a significant risk factor for not receiving pelvic exams, but not mammograms. Household income and age did not reach significance as risk factors in either analysis.

CONCLUSIONS

Women with physical disabilities are at a higher risk for delayed diagnosis of breast and cervical cancer, primarily for reasons of environmental, attitudinal, and information barriers. Future research should focus on the subpopulations that were not surveyed adequately in this study, women with disabilities who have low levels of education or income, or who are of minority status.
