Cancer screening in public health clinics: the importance of clinic utilization

A study on people's concepts associating community health exam interventions with their participation in future health examinations

This study primarily employed the health belief model (HBM) to identify the effect between health examination services and intentions to continue receiving health examinations. The research participants (n = 905) were people who received a health examination in a hospital in Central Taiwan in 2012. The study conducted an anonymous questionnaire survey to collect data and implemented cross-sectional research to examine the factors. The results for the threat construct the participants who showed concern regarding potential physical conditions, and the causes of diseases were more likely to anticipate in health examinations. The participants who indicated their intentions to modify dietary and exercise regimen according to their health examination reports were more likely to anticipate examinations. The results for the cues to action construct showed that the participants who considered advice from others were more inclined to undergo examinations. The results for the barriers construct found that factors, including anxiety, concern for personal-information disclosure. Providing community health examinations helps health care facilities understand people's concepts regarding health examinations and ensures that hospitals enhance the delivery of health examinations to satisfy people's demands and achieve community health.

Ohio Appalachian women's perceptions of the cost of cervical cancer screening

BACKGROUND

Despite evidence of the importance of cervical cancer screening, screening rates in the United States remain below national prevention goals. Women in the Appalachia Ohio region have higher cervical cancer incidence and mortality rates along with lower cancer screening rates. This study explored the expectations of Appalachian Ohio women with regard to Papanicolaou (Pap) test cost and perceptions of cost as a barrier to screening.

METHODS

Face-to-face interviews were conducted with 571 women who were part of a multilevel, observational community-based research program in Appalachia Ohio. Eligible women were identified through 14 participating health clinics and asked questions regarding Pap test cost and perceptions of cost as a barrier to screening. Estimates of medical costs were compared with actual costs reported by clinics.

RESULTS

When asked about how much a Pap test would cost, 80% of the women reported they did not know. Among women who reportedly believed they knew the cost, 40% overestimated test cost. Women who noted cost as a barrier were twice as likely to not receive a test within screening guidelines as those who did not perceive a cost barrier. Furthermore, uninsured women were more than 8.5 times as likely to note cost as a barrier than women with private insurance.

CONCLUSIONS

Although underserved women in need of cancer screening commonly report cost as a barrier, the findings of the current study suggest that women may have a very limited and often inaccurate understanding concerning Pap test cost. Providing women with this information may help reduce the impact of this barrier to screening.

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

OBJECTIVE

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

METHOD

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

RESULTS

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

CONCLUSION

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

Breast Cancer Screening in Women Surviving Hodgkin Disease

OBJECTIVE

To inform female Hodgkin disease (HD) survivors, younger than 35 at diagnosis, of their increased risk for breast cancer and encourage them to seek breast cancer screening.

METHODS

An evidence-based intervention, telephone counseling, was used in a pre-post test design, randomized trial with the control group being offered the intervention following the post-test. Women treated at Stanford University who received thoracic irradiation before age 35, alive and HD-free at last contact, were referred to the project (n = 471). Of 261 eligible women who could be located, 157 completed the pretest and were randomized (60% response rate) and 133 completed the post-test (85% retention rate).

RESULTS

There was a positive intervention effect on mammography maintenance: the odds of being in maintenance at post-test compared with pretest were greater in the intervention group than in the control group [odds ratio (OR) = 3.6]. Women were more likely to be in mammography maintenance at pre- or post-test if at pretest they were married (OR = 5.7), employed (OR = 2.3), more worried about breast cancer (OR = 1.4 per unit of scale), or received an annual physical examination (OR = 2.2). Women under age 40 were much less likely to be in maintenance than were those age 45 and over (age 35-39, OR = 0.2; under age 35, OR = 0.07).

CONCLUSIONS

The findings indicate that providing risk information encourages cancer survivors to take health preventive actions. Telephone counseling is a method that can provide risk information and is easily transferable to settings where people seek health information, such as telephone information lines.

Geographic disparities in cervical cancer mortality: what are the roles of risk factor prevalence, screening, and use of recommended treatment?

CONTEXT

Despite advances in early detection and prevention of cervical cancer, women living in rural areas, and particularly in Appalachia, the rural South, the Texas/Mexico border, and the central valley of California, have had consistently higher rates of cervical cancer mortality than their counterparts in other areas during the past several decades.

METHODS

This paper reviews the published literature from 1966 to July 2002 to assess three potential pathways underlying this excess mortality--high human papilloma virus (HPV) prevalence, lack of or infrequent screening and advanced disease at diagnosis, and under-use of recommended treatment and shorter survival.

FINDINGS

Living in rural areas may impose barriers to cervical cancer control, including lack of transportation and medical care infrastructures. Population characteristics that place women at greater risk for developing and dying from cervical cancer, such as low income, lack of health insurance, and physician availability, are concentrated in rural areas. Published data, however, are insufficient to identify the key reasons for the observed mortality patterns.

CONCLUSIONS

At this time, given the lack of definitive evidence in the published literature, decisions about priorities in areas with high rates of cervical cancer mortality will depend on knowledge of current levels of screening, incidence, and stage distribution; and service delivery infrastructures, resources, and acceptability of interventions to the target population.

Computerized Training in Breast Self-examination

Fifty-eight women recruited from a community health center completed either a brief interactive multimedia training program on breast self-examination using a breast model and computer guided feedback on accuracy of lump detection or read a National Cancer Institute pamphlet on breast self-examination and breast lumps. Women using the computer program as compared to the pamphlet group reported a higher sense of self-efficacy for being able to perform a breast self-examination immediately after their educational session and 1 month later. However, the increase in self-efficacy for the computer group diminished over 4 weeks, underscoring the importance of an environment that reminds and reinforces learning for women about the performance of regular breast self-examination. The increase in sense of self-efficacy to perform breast self-examination with roughly 20 minutes of computer-based training and the partial maintenance of that self-efficacy 30 days later suggests the utility of incorporating short, focused interventions in busy primary healthcare settings.

Delivery of preventive services for low-income persons over age 50: a comparison of community health clinics to private doctors' offices

This study focused on the use of 14 evidence-based preventive services for the low-income population over age 50: colorectal, breast and cervical cancer screening, cholesterol screening, counseling around diet, exercise, tobacco, alcohol and illicit drugs, and immunizations for influenza, tetanus and pneumonia. Population characteristics and rates of delivery of these preventive services are compared for low-income users of community health clinics vs private doctors' offices/HMOs. Three nationally representative data-files from the National Health Interview Survey--the Person-Level File, Sample Adult File, and Sample Adult Prevention File--were linked to obtain the necessary data on preventive services use in the 12,024 persons over age 50. Among the population of persons over age 50 living below 200% of the poverty threshold, those using community clinics were more likely to be younger, a racial or ethnic minority, less formally educated, in poorer health, uninsured, and more likely to face time, transportation or cost barriers to obtaining health care (p < .01 for all comparisons), than their counterparts using private doctors' offices/HMOs. Community health clinics performed as well as private doctors/HMOs in the delivery of cancer screening, cholesterol screening and immunizations to lower income persons over 50 years. Rates of counseling about diet and exercise were higher among users of private doctor's offices than among users of community health clinics users (40% vs. 31% respectively, p = .02). Despite the severe resource constraints under which they operate, and the greater vulnerability of the population they serve, community clinics deliver preventive services at rates comparable to private doctors' offices and HMOs.

Comparison of mammography use by older black and white women

OBJECTIVES

To identify differences in the prevalence of ever having had a mammogram and having had a recent mammogram between older black and white women and to compare factors associated with mammography use in older black and white women.

DESIGN

Data analysis and comparative study using nationally representative multistage sampling survey.

SETTING

Data were obtained from the 1998 National Health Interview Survey.

PARTICIPANTS

Four hundred forty-nine black and 3,328 white older women were examined.

MEASUREMENTS

The outcome variables included never having had a mammogram (yes/no) and not having had a mammogram in the past 3 years (yes/no).

RESULTS

The results of chi-square tests showed that older blacks were less likely to have ever had a mammogram than older whites, but there was no difference in having had a recent mammogram between older blacks and whites. After adjusting for other related factors, race was not related to mammography use in older blacks and whites. Health insurance was related to mammography use in older whites but not in older blacks. Family income was associated with never having had a mammogram in older whites but not in older blacks. Older blacks with less than 12 years of education were less likely to have had a mammogram (recently or ever) than older whites with less than 12 years of education.

CONCLUSIONS

Even though race, per se, was not associated with mammography use in older black and white women, many barriers to mammography use between older black and white women were different or did not have similar effects. To promote mammography use in older black and white women, barriers need to be specifically targeted for each group to enhance the effectiveness of breast cancer screening programs.

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.
