Factors associated with repeat mammography screening

BACKGROUND: Even organizations with differing mammography recommendations agree that regular repeat screening is required for mortality reduction. However, most studies have focused on one-time screening rather than repeat adherence. We compare trends in beliefs and health-related behaviors among women screened and adherent to the National Cancer Institute's screening mammography recommendations (on schedule), those screened at least once and nonadherent (off schedule), and those never screened. METHODS: Our data are from a baseline telephone interview conducted among 1,287 female members of Blue Cross Blue Shield of North Carolina who were aged either 40 to 44 years or 50 to 54 years. RESULTS: The 3 groups differed significantly on beliefs and health-related behaviors, with the off-schedule group almost consistently falling between the on-schedule and never screened groups. Off-schedule women were more likely than on-schedule women, but less likely than those never screened, to not have a clinical breast examination within 12 months, to be ambivalent about screening mammography, to be confused about screening guidelines, and to not be advised by a physician to get a mammogram in the past 2 years. Off-schedule women perceived their breast cancer risk as lower and were less likely to be up to date with other cancer screening tests. CONCLUSIONS: Our findings suggest that women who are off schedule are in need of mammography-promoting interventions, including recommendations from and discussion with their health care providers. Because they are more positive and knowledgeable about mammography than women who have never been screened, they may benefit from brief interventions from health care providers that highlight the importance of repeat screening.     

Factors associated with screening mammography and breast self-examination intentions

The factors associated with the use of two methods for the early detection of breast cancer were assessed using a theoretical framework derived from the theory of reasoned action and the Health Belief Model. Telephone interviews were conducted with 170 women aged between 50 and 70 years, randomly selected from the telephone directory of a provincial city in Victoria, Australia. The model explained 47% of the variance in intentions to have a mammogram and 22% of the variance in intentions to practise breast self-examination (BSE). The data supported the prediction that different variables would be associated with each method of early detection of breast cancer. Intentions to have a mammogram were associated with perceived susceptibility to breast cancer, knowing a woman who has had a mammogram, previous mammography history and Pap test history. Intentions to do BSE were associated with self efficacy, knowledge of breast cancer issues, concern about getting breast cancer and employment status. Both screening methods were associated with prior behaviour and concern about getting breast cancer.     

Factors associated with women''s adherence to mammography screening guidelines.

OBJECTIVE: To examine individual and environmental factors associated with adherence to mammography screening guidelines. DATA SOURCES: A unique data set that combines a national probability sample (1992 National Health Interview Survey); a national probability sample of mammography facility characteristics (1992 National Survey of Mammography Facilities); county-level data on 1990 HMO market share; and county-level data on the supply of primary care providers (1991 Area Resource File). STUDY DESIGN: The design was cross-sectional. DATA EXTRACTION/ANALYSIS: Data sets were linked to create an individual-level sample of women ages 50-74 (weighted n = 2,026). We used multipart, sequential logistic regression models to examine the predictors of having ever had mammography, having had recent mammography, and adherence to guidelines. We categorized women as adherent if they reported a lifetime number of exams appropriate for their age (based on screening every two years) and they reported having had an exam in the past two years. PRINCIPAL FINDINGS: Only 27 percent of women had the age-appropriate number of screening exams (range 16 percent-37 percent), while 59 percent of women had been screened within two years. Women were significantly more likely to adhere to screening guidelines if they reported participating with their doctor in the decision to be screened; were younger; had smaller families, higher education and income, and a recent Pap smear; reported breast problems; and lived in an area with a higher percentage of mammography facilities with reminder systems, no shortage of primary care providers, higher HMO market share, and higher screening charges. CONCLUSIONS: A small percentage of women adhere to screening guidelines, suggesting that adherence needs to become a focus of clinical, programmatic, and policy efforts.     

Estimating cancer screening indicators in the primary care setting

The software "Profile: A Cancer Risk Profile of Your Patient Practice" was used to estimate cancer screening activities in a primary care practice. "Profile" is a public health tool that does not track the screening histories of individual patients, but rather, using a sampling strategy, provides estimates for the entire practice of the age and sex specific number of screening eligible patients, the number screened, and the number that should have been screened, based on National Cancer Institute/American Cancer Society (NCI/A CS) guidelines. This report describes "Profile," and the results it generated from a sample of medical records. Primary care providers who seek to integrate primary and secondary cancer prevention activities into their routine practices will find it useful to have an objective estimate of their current level of such activities.     

Correlates of screening mammography in a family practice setting

The medical records of 243 asymptomatic women aged 50 years or older were reviewed at a community-based family practice center to determine the proportion who had been referred for a screening mammogram and to identify correlates of mammography referral. Patient demographic characteristics, breast cancer risk factors, and characteristics of past patient-physician encounters were considered. Between July 1, 1981, and July 1, 1987, 40 (16 percent) of the women had received a mammography referral from their currently assigned physician. All but two of the women had actually obtained the mammogram. The primary predictors of mammography referral were the known risk factors for breast cancer: a family history of breast cancer (prevalence rate ratio [PRR] = 9.3, P = .001) and a history of benign breast disease (PRR = 7.9, P = .002). Other predictors included having a Papanicolaou test performed by the current physician (PRR = 4.1, P = .03), having a test for stool occult blood returned by the patient (PRR = 10.2, P = .003), having been instructed in smoking cessation by the current physician (PRR = 10.0, P = .05), and, possibly, being a former smoker (PRR = 4.6, P = .09). Patient demographic characteristics, other known breast cancer risk factors (age, obesity, alcohol use, and pregnancy history), and the sex of the physician were not predictive.     

Computerized administration of alcoholism screening tests in a primary care setting

This study compared the use of computerized versus paper-and-pencil administration of three commonly employed alcohol screening tests--the Short Michigan Alcoholism Screening Test (SMAST-13), CAGE (an acronym for four questions to discern problem drinking), and a quantity-frequency scale. These instruments were administered to 280 adults receiving health care in three primary care clinics in south-central Wisconsin. One hundred forty patients were randomly assigned to complete these instruments on a Macintosh SE, and 140 were assigned to the paper-and-pencil versions. Patients were classified as alcoholic based on responses to the Diagnostic Interview Schedule and DSM-III criteria. Results indicated the sensitivity and specificity of these instruments were similar for the two methods of administration. The sensitivity of the SMAST-13 was 0.56 for computer administration and 0.58 for the pencil-and-paper form. The findings suggest that computer administration of these instruments is at least as effective as use of the standard pencil-and-paper method. The data show that computers can be used for direct entry of information by patients, avoiding separate coding of paper-and-pencil information into a computerized format for clinical systems that use system-wide computerization of medical information.     

Factors associated with inadequate cervical cancer screening among lower income primary care patients

This study identified factors associated with cervical cancer screening patterns among lower income primary care patients. One hundred forty-one women completed a self-administered questionnaire before their medical visit. The results indicated that 71 percent had a Papanicolaou (Pap) test in the past year, 14 percent had one between 1 and 3 years ago, and 15 percent had not had a Pap test for 3 or more years. Advanced age was associated with a reduced likelihood of adequate screening; 21 percent of women aged 50-64 years and 39 percent of those aged 65 years and older had not had a Pap test in the past 3 years. Factors positively associated with screening included perceived susceptibility to cervical cancer and the belief in the efficacy of Pap tests and benefits of screening. Fear of finding cancer was a significant barrier to cervical screening in this population. Of those women who had not been screened adequately, 58 percent were interested in obtaining Pap tests in the primary care setting. The implications for promoting cervical cancer screening in primary care practices are discussed.     

Factors associated with repeat mammography in a New York State public health screening program.

Screening mammography is the most effective method for early detection of breast cancer, but repeat mammography rates are not optimal in most populations. Since 1988, New York State has supported a program of breast cancer screening for underserved, uninsured, or underinsured women. The present study was designed to identify sociodemographic and clinical factors associated with failure to return for repeat mammography screening after a negative initial mammogram. Of women initially screened between 1988 and 1991 (N = 9,485), 27 percent obtained repeat mammograms by 1993. The final logistic regression model contained program site, race and ethnicity, family income, and time since last mammogram.     

Factors associated with pneumococcal vaccine uptake among vulnerable older adults in the United States primary care setting

Pneumococcal vaccine uptake targets set by Healthy People 2020 were not met by 2019 among vulnerable United States populations, yet research suggests progress can be made in primary care settings. This study assessed factors associated with having gotten a pneumococcal vaccine among vulnerable adults aged 50 and older. This study used the 2018 Medical Expenditure Panel Survey nationally representative dataset. Eligible individuals were aged 50–64 with an ‘at risk’ health condition or ≥65 years and had a primary care provider as their usual source of care (N = 3,760). Binary logistic regression was used to test factors (identified from literature) for a significant association with getting the pneumococcal vaccine. Factors with significant associations were entered into an adjusted multivariable logistic regression model to generate the odds of endorsing a factor given that the respondent got the vaccine. Collinearity among variables was examined with an unacceptable threshold of 0.8 correlation. A significance threshold of 0.05 was used. Those who got the pneumococcal vaccine had 16.7 (p < 0.001), 16.0 (p < 0.001) and 11.0 times (p < 0.001) higher odds of having also gotten the influenza vaccine, the herpes zoster vaccine and a colonoscopy respectively. They had 3.86 times (p = 0.009) higher odds of having diabetes mellitus, 0.036 times (p = 0.019) higher odds of having visited their doctors three times in 2018 and 8.4 times (p = 0.009) higher odds of having seen their doctor within the last year. Concordance statistic for model fit was 0.936. There was a negative association between pneumococcal vaccination and going to three doctor office visits in 2018 vs only once. The strongest positive associations were found between pneumococcal vaccination and getting the herpes zoster vaccine, influenza vaccine and getting a colonoscopy. These results suggest that those who choose to get the pneumococcal vaccine may have higher odds of also getting other vaccines or specific preventative screenings.     

Factors associated with the use of primary care services: the role of practice nurses

Rising demand for and costs of health care have led to an increasing role of practice nurses in primary care in many countries, including the United Kingdom. Previous research has explored how practice nurse care differs from that provided by general practitioners (GPs) in terms of costs and health outcomes, and has highlighted the importance of matching skills and experience with roles and responsibilities. However, there has been little research to compare the characteristics of patients seen by GPs and practice nurses in primary care. We aim to investigate the factors associated with the use of practice nurse visits, and to compare these with the factors associated with GP use. We jointly model the use of practice nurse and GP visits using a bivariate probit regression model with a large set of covariates taken from two rounds of the Health Survey for England (2001, 2002). We find that practice nurse use is associated with age and gender, health, socioeconomic and supply variables. There are differences in the factors associated with practice nurse and GP use. Chronically ill patients are more likely to see a practice nurse, while acute ill health has a stronger association with the probability of seeing the GP. Practice nurse use is also correlated with a narrower range of health conditions compared with GP use. We also found differences between practice nurse and GP visits with respect to the association with economic activity, ethnic group, number of children, degree of urbanisation, and distance to practice.     

Feasibility of sigmoidoscopic screening for bowel cancer in a primary care setting

Sigmoidoscopic screening for bowel cancer is controversial because of its debatable efficacy, lack of patient and physician acceptance of the procedure, and uncertainty about its practicality with the large numbers of patients in primary care settings. This study addressed patient acceptance and practicality. During an 18-month period, 75 percent of all patients aged 50 years and greater who were seen for health maintenance accepted sigmoidoscopy. The procedure was integrated into office routines without disrupting other patient care. While compliance with fecal occult blood testing was high (88 percent), sensitivity of this test for neoplastic polyps within reach of the proctosigmoidoscope was low (11 percent). These results suggest that acceptance of sigmoidoscopy by patients seen in family physicians' offices could be greater than has been anticipated.     

Microcomputer-generated reminders. Improving the compliance of primary care physicians with mammography screening guidelines

Recent studies have documented that physician compliance with recommended periodic health screening improves with reminders to physicians. These reminders, however, are often costly to maintain and modify. This study investigates the influence of a microcomputer tickler system on the ordering of mammograms. All women (N = 1262) aged 40 years and older who made visits to an outpatient office during a 6-month period were randomly assigned to one of two groups. For the experimental group, the date of the last mammogram ordered and recorded in the clinical database was printed on the encounter form generated for each patient visit. No information regarding previous mammograms was printed for patients in the control group. Women in the experimental group were more likely to have a mammogram ordered during the study period (19% compared with 12%, P = .001) and, as a result, were more likely to be in compliance with mammography guidelines at the study's completion (27% compared with 21%, P = .011). Microcomputerized data storage and retrieval systems may help increase physicians' attention to preventive health screening recommendations.     

Factors associated with mammography screening among Reunionese women : a cross-sectional study

ObjectiveTo explore the factors associated with the uptake of mammography screening in Reunionese women aged 50-65 years.MethodsThis study included all women aged 50 to 65 years participating in a population-based cross-sectional study "FOSFORE". Participants were recruited between March and June 2017 using two sampling frames. The first frame consisted of households with a landline telephone, with or without a mobile line, by first randomly generating a telephone number and then randomly selecting an individual from among all eligible women in the household. The second sampling frame was constituted of women with an exclusive mobile line, who were selected directly if they met the eligibility criteria. Data were weighted for age and socio-professional status to ensure representativeness at the Reunion Island level. Weighted logistic regression was used to calculate odds ratios while adjusting for confounders.Results417 women were included in the study; 63.8% were up to date with guidelines on mammography screening and 36.2% were not up to date. Four factors were significantly associated with mammography screening, with an adjusted odds ratio of 2.92 (95% CI 1.51–5.61) for not having an Active Solidarity Income, 1.98 (95% CI 1.22–3.23) for having a regular gynecological follow-up by a physician, 6.53 (95% CI 3.23–13.21) for performing a Pap smear test in the past two years, and 2.07 (95% CI 1.21–3.52) for having an adequate literacy level (HLQ3).ConclusionThe findings of this study suggest that higher socio-economic status is an indicator of participation in mammography screening in La Réunion, and future educational and intervention programs should target women in deprived areas.     

Factors influencing mammography use among women in Medicare managed care

This article presents findings about the mammography screening experience of Medicare members of a health maintenance organization (HMO). Based on a mail survey of 309 women, we assessed factors that may be facilitators or barriers to this service for older women. The results indicate that these respondents generally are receiving timely mammograms; over three-quarters (79 percent) reported having a mammogram in the past 2 years. Multivariate analysis showed that women who were younger (under 75 years of age), believed in the importance of screening, had been told by a physician to obtain a mammogram, and were more satisfied with their physician and more likely to report mammography use.     

Cognitive motivations associated with screening mammography in Cyprus

BACKGROUND: This study examined the relationship between cognitive motivations, demographic characteristics, related preventive health behaviors, and intention to obtain a first screening mammogram among Greek Cypriot women. METHODS: This cross-sectional study took place at the outpatient clinics of the General Hospital of Nicosia during the fall of 1999. The participants were 293 women asymptomatic of breast cancer and with no previous mammographic experience. The Theory of Planned Behavior in conjunction with the construct of self-efficacy was used in the development of the questionnaire. The assessment also included demographic information, practice of other preventive health behaviors, and knowledge of breast cancer screening. RESULTS: Self-efficacy was the most significant determinant of initial screening mammography, followed by normative beliefs associated with the physician, family and close friends, and perceived behavioral control beliefs related to barriers to obtaining a mammogram. Educational level, time of last clinical breast examination, and status of breast self-examination were also strongly implicated in the explanation of initial screening mammography. CONCLUSIONS: Insights into specific salient motivational cognitions and certain demographic characteristics or related preventive health behaviors are crucial to the development and implementation of effective intervention strategies.

Use of nonphysician health care providers for skin cancer screening in the primary care setting

BACKGROUND: Nonphysician health care providers are in an optimal position to provide cancer prevention and screening services. METHODS: We conducted a survey of primary care physicians to determine physician use and amenability to use of nonphysician health care providers to perform skin cancer screening in comparison with other cancer screening examinations. RESULTS: A total of 1,363 eligible physicians completed the survey. Of these, 631 physicians (46%) reported a nurse practitioner or physician assistant performing at least one type of cancer screening examination on their patients. Twenty-nine and 22% of all physicians reported nurse practitioners or physician assistants performing skin cancer screening, respectively. Family physicians were more likely to use nurse practitioners and physician assistants to perform these cancer screening examinations than internists (chi(2) test, P = 0.001 for each examination). Skin examinations were performed less frequently by nurse practitioners and physician assistants than all other cancer screening examinations. A total of 73-79% of family physicians and 60-70% of internists were amenable to having a nonphysician health care provider perform one or more of these examinations. CONCLUSIONS: Primary care physicians are currently utilizing nonphysician health care providers to perform cancer screening examinations and the majority of those surveyed are amenable to the use of these providers for such examinations. This suggests that one possible strategy for increasing skin cancer screening is through an expanded role of nonphysician health care providers.
