Has the use of cervical, breast, and colorectal cancer screening increased in the United States?

Preventive services among Medicare beneficiaries with supplemental coverage versus HMO enrollees, medicaid recipients, and elders with no additional coverage

BACKGROUND

Studies conducted when Medicare began to cover preventive services, found that beneficiaries with supplemental insurance were much more likely to have such services than those without additional coverage.

OBJECTIVE

To examine preventive services among Medicare beneficiaries with supplemental insurance, Medicaid, health maintenance organization (HMO) enrollees, and those without additional insurance.

RESEARCH DESIGN

Analysis of the 1996 Medical Expenditure Panel Survey, a nationally representative multistage survey.

SUBJECTS

2,251 persons aged 65 and older with Medicare coverage.

MEASURES

Self-reported preventive services, specifically, blood pressure measurement, cholesterol testing, influenza vaccination, mammography, Papanicolau (Pap) testing, and breast and prostate examinations. Multivariate modeling was used to adjust for age, education, race/ethnicity, and functional status.

RESULTS

Elders without additional coverage were approximately 10% points less likely to have influenza vaccination, cholesterol testing, mammography, or Pap smears than those with supplemental coverage (P < 0.05). Multivariate adjustment attenuated some of these differences with age and education being the most important predictors of having preventive services. HMO enrollees were more likely to have mammograms than those with supplemental coverage (P < 0.05).

CONCLUSIONS

Several years after Medicare extended coverage to include preventive services, differences in utilization of such services among elders with and without supplemental insurance have narrowed substantially.

Factors important in promoting cervical cancer screening among Canadian women: findings from the 1996-97 National Population Health Survey (NPHS)

Although routine Pap screening represents an effective tool in the early detection of cervical cancer, it remains underused by some Canadian women. This study examines selected sociodemographic, health, lifestyle, and system barriers to Pap test participation among 33,817 women aged 18+ years in the cross-sectional 1996-97 National Population Health Survey (NPHS). Among women 18 years and over, 87% reported ever having had a Pap test while 72% reported a recent (< 3 years) test. A report of ever and recent use was most common among women 25-34 (92% and 86.9%, respectively). Only 0.6% of recently screened women reported access problems. Among those without a recent test, most (53%) reported that they did not think it was necessary. Pap test use varied little across provinces and was less common among older and single women, those with lower education, a spoken language other than English, a birth place outside Canada and negative health and lifestyle characteristics.

The role of inadequate health literacy skills in colorectal cancer screening

Colorectal cancer is ideally suited for early detection strategies that are likely to improve survival rates. Screening with either a fecal occult blood test (FOBT) or flexible sigmoidoscopy has been shown to identify precancerous polyps or cancers in early stages. However, persons with limited education and of lower socioeconomic status infrequently participate in screening programs in general and have very low rates of colorectal screening. Low literacy, which is common among persons with limited education and low income, may be an overlooked factor in understanding patients' decision making about colorectal cancer screening. This article provides information from focus groups about colorectal cancer screening, which we examine in the context of relevant literature on cancer screening and literacy. Using the health belief model, we examine the association between inadequate health literacy skills and low rates of colorectal cancer screening. The theoretical model also provides insights into strategies for improving knowledge, attitudes, and beliefs and screening rates for this challenging patient population.

Promoting breast and cervical cancer screening at the workplace: results from the Woman to Woman Study

OBJECTIVES

This article reports findings from a peer-delivered intervention designed to increase use of breast and cervical cancer screening.

METHODS

Twenty-six worksites were randomly assigned to the intervention or comparison group. The 16-month intervention consisted of group discussions, outreach, and educational campaigns. Data were collected from a random sample of women employees stratified by age (baseline n = 2943; final n = 2747). Cross-sectional analyses were conducted to evaluate the impact of the intervention on screening behaviors.

RESULTS

Relative to comparison worksites, the intervention group experienced greater increases in the percentage of women who reported a recent mammogram (7.2% vs 5.6%), clinical breast examination (5.8% vs 2.1%), and Papanicolaou (Pap) test (4.7% vs 1.9%). After worksite cluster and age strata were controlled for, the observed increase in Pap tests was significantly greater in the intervention group (odds ratio [OR] = 1.28; 95% confidence interval [CI] = 1.01, 1.62); however, differences in mammography screening rates (OR = 1.14; 95% CI = 0.90, 1.44) and clinical breast examination (OR = 1.19; 95% CI = 0.96, 1.49) were not statistically significant.

CONCLUSIONS

Intervention activities produced a modest increase in cervical cancer screening, but they did not accelerate breast cancer screening rates above the observed secular trend.

Predictors of mammography use among Canadian women aged 50-69: findings from the 1996/97 National Population Health Survey

BACKGROUND

Screening mammography, although recommended every 2 years for women aged 50-69, is thought to be underused among select groups of Canadian women.

METHODS

We used data from the 1996/97 National Population Health Survey to describe current patterns in mammography use (including reasons for not having a mammogram within the 2 years before the survey and future screening intentions) in Canada and to determine factors associated with nonparticipation and time-inappropriate use (mammogram 2 or more years before the survey) among women aged 50-69.

RESULTS

Among respondents aged 50-69, 79.1% (95% confidence interval [CI] 76.9%-81.2%) reported ever having had a mammogram, and 53.6% (95% CI 51.4%-55.9%) had had a recent (time-appropriate) mammogram (within the 2 years before the survey). Only 0.6% (95% CI 0.3%-0.9%) of recently screened women reported problems of access, and few reported personal or health system barriers as reasons for not obtaining a recent mammogram. Over 50% of the women who had not had a recent mammogram reported that they did not think it was necessary, and only 28.2% (95% CI 23.8%-32.7%) of those who had never had a mammogram planned to have one within the 2 years following the survey. The rate of time-appropriate mammography varied significantly by province, from 41.1% (95% CI 29.3%-52.9%) in Newfoundland to 69.4% (95% CI 61.3%-77.6%) in British Columbia. Significant predictors of never having had a mammogram included higher age, residence in a rural area, Asia as place of birth, no involvement in volunteer groups, no regular physician or recent medical consultations (including recent blood pressure check), current smoking, infrequent physical activity and no hormone replacement therapy.

INTERPRETATION

Despite increases in mammography screening rates since the 1994/95 National Population Health Survey, current estimates indicate that almost 50% of women aged 50-69 have not had a time-appropriate mammogram. Our findings confirm continued low mammography participation rates among older women and those in rural areas, select ethnic groups and women with negative health care and lifestyle characteristics.

Improving cervical cancer screening in hospital settings

BACKGROUND

Identifying opportunities to offer cervical cancer screening to underscreened women is important for increasing early detection. Maryland law mandates offering Pap tests during hospital admissions. We examined organizational and physician attitudes and practices regarding inpatient screening, to identify mechanisms for increasing the law's effectiveness.

METHODS

We analyzed state admission data, a hospital administrators telephone survey, and a mailed survey of Maryland primary and specialty care physicians, to identify overall patterns and subgroup differences regarding screening.

RESULTS

Overall, we found significant concern regarding cancer, and evidence of policies and procedures for screening. However, most hospitals and providers offered screening without assessing clinical need or including persuasive recommendations. Providers with significantly less engagement in preventive assessment and screening included medical and surgical subspecialists and non-primary care providers. Providers to African-American and Medical Assistance women were also less likely to have knowledge, attitudes, and practices conducive to inpatient screening.

CONCLUSIONS

Adequate support and infrastructure for preventive screening exist within hospitals. Adding clinical assessment and persuasive education could in crease the impact of these mechanisms, and improve prevention among underscreened inpatient populations.

Cultural barriers to mammography, clinical breast exam, and breast self-exam among Chinese-American women 60 and older

BACKGROUND

This study examined screening utilization at least once and regular adherence to mammography, clinical breast exam, and breast self-exam among older Chinese-American women.

METHOD

One hundred women were recruited from senior centers in two metropolitan cities. Participants completed a questionnaire that included sections on demographics, health history, health insurance coverage, breast cancer screening, common and cultural barriers to screening, and acculturation.

RESULTS

Logistic regression models found insurance coverage for mammography and acculturation to be significant predictors of having had a mammogram at least once. Low perceived need/lack of physician recommendation and recency of physical examination were significant predictors of having had a mammogram in the past year. Acculturation and modesty were significant predictors of having had a clinical breast exam at least once, while recency of physical examination was a significant predictor of having had a clinical breast exam in the past year. Reliance on medial professionals for screening and forgetting were significant predictors of having performed breast self-exam at least once, and forgetting was a significant predictor of regular performance of breast self-exam.

CONCLUSIONS

These findings suggest that both common and cultural barriers play a role in breast cancer screening among older Chinese-American women, with cultural factors being more influential in the initiation of cancer screening behavior.

The practices and attitudes of primary care nurse practitioners and physician assistants with respect to colorectal cancer screening

OBJECTIVES

Although nurse practitioners and physician assistants form a large and growing portion of the primary care workforce, little is known about their colorectal cancer screening practices. The aim of this study was to assess the colorectal cancer screening practices, training, and attitudes of nurse practitioners and physician assistants practicing primary care medicine.

METHODS

All nurse practitioners (827) and physician assistants (1178) licensed by the Medical Board of the State of North Carolina were surveyed by mail. Both groups were further divided into primary care versus non-primary care by self-described roles. Self-reported practices, training, and attitudes with respect to colorectal cancer screening were elicited.

RESULTS

Response rates were 71.4% and 61.2%, for nurse practitioners and physician assistants respectively. A total of 51.3% of nurse practitioners and 50.3% of physician assistants described themselves as adult primary care providers. No primary care nurse practitioners and only 3.8% of primary care physician assistants performed screening flexible sigmoidoscopy. However, 76% of primary care physician assistants and 69% of primary care nurse practitioners reported recommending screening flexible sigmoidoscopy. A total of 95% primary care physician assistants and 92% of primary care nurse practitioners reported performing fecal occult blood testing. Only 9.4% of physician assistants and 2.8% of nurse practitioners received any formal instruction in flexible sigmoidoscopy while in their training. Additionally, 41.4% of primary care physician assistants and 27.7% of primary care nurse practitioners reported that they would be interested in obtaining formal training in flexible sigmoidoscopy.

CONCLUSIONS

Physician assistants and nurse practitioners are motivated, willing and underutilized groups with respect to CRC screening. Efforts to increase education and training of these professionals may improve the availability of CRC screening modalities.

Colorectal cancer screening participation by older women

OBJECTIVE

Although recent screening guidelines recommend annual fecal occult blood testing (FOBT) for adults aged > or = 50, a number of studies report that these tests are underused. Systematic efforts to increase awareness of colorectal cancer (CRC) and to promote screening participation are needed to meet national objectives for CRC control.

METHODS

This study examined CRC-screening practices and evaluated factors related to recent participation in screening by FOBT in a sample of women aged 50 to 80 who were surveyed about their use of clinical preventive services at Group Health Cooperative, a managed care organization in western Washington State.

RESULTS

Of the 931 women eligible for analysis, 75% reported ever having been screened by FOBT and 48% reported having been screened within 2 years before the survey. Participation in screening did not vary by demographic characteristics or by perceived or actual risk of CRC. Women with a positive attitudes toward CRC screening had sevenfold greater odds of recent screening by FOBT (odds ratio=7.1; 95% confidence interval, 4.4 to 11.6). Only 58% of study women reported that their physicians encouraged CRC screening, but this factor was strongly related to participation (odds ratio=12.7; 95% confidence interval, 6.6 to 24.4).

CONCLUSIONS

We identified several areas in which understanding of CRC risk may be low. As a whole, these findings suggest that effective strategies to control CRC may include efforts to improve knowledge of risk and prevention, but must also appeal directly to primary care physicians to identify and address their barriers to screening recommendations.

Cancer of the colon and rectum in California: trends in incidence by race/ethnicity, stage, and subsite

BACKGROUND

Incidence and mortality from cancer of the colon and rectum have declined in recent years in the United States and California, but reasons for the decline are unknown.

METHODS

Age-adjusted site-specific and stage-specific incidence rates were calculated for approximately 9,000 cases of in situ cancer and 120,000 cases of invasive cancer of the colon and rectum diagnosed between 1988 and 1996 among California residents and reported to the California Cancer Registry. Trends in incidence over time were measured using the estimated annual percent change.

RESULTS

Among non-Hispanic whites there was a decline in all sites and stages, but the decrease was most pronounced for rates of in situ and regional/distant tumors in the rectum and sigmoid which declined by about 4 to 7% a year. For tumors in the proximal colon, the decrease was statistically significant only for regional/distant tumors which declined about 2% a year. Among blacks, there was an approximately 7% annual decline in the incidence of regional/distant tumors of the rectum in women and a nearly 3% a year decrease in regional/distant tumors of the proximal colon in men. The decline in rates for Hispanics and Asian/Pacific Islanders was smaller and less consistent than for non-Hispanic whites.

CONCLUSIONS

The results confirm a overall decline in all stages of cancer of the colon and rectum in California, particularly among non-Hispanic white men and women. The decrease was most pronounced for tumors in the rectum and sigmoid colon and may be attributable to screening.

Breast and cervical carcinoma mortality among women in the Appalachian region of the U.S., 1976-1996

BACKGROUND

Previous studies have shown high cervical carcinoma mortality and increasing breast carcinoma mortality in the Appalachian region of the U.S. (which includes parts of 12 states and all of West Virginia). In the current study the authors report trends in breast and cervical carcinoma death rates among women in Appalachia for 1976-1996.

METHODS

Death rates were calculated from information provided on death certificates and reported to the National Center for Health Statistics for Appalachian women and for women living elsewhere in the U.S. ("other U.S. women"). Trends were examined with joinpoint regression techniques overall and by age and race. Average annual mortality rates were calculated by state for 1992-1996 for each state's Appalachian and non-Appalachian areas.

RESULTS

Overall breast carcinoma mortality was lower among Appalachian women than among other U.S. women throughout the study period; however, after rates decreased among both groups in the 1990s, the difference appears to have narrowed. No such decline was observed for women age >/= 70 years. Overall cervical carcinoma mortality was higher among Appalachian women than among other U.S. women but decreased during the study period to rates closer to those for other U.S. women. No significant decrease was observed among women age < 50 years. Overall, for both black and white women, breast carcinoma mortality was lower and cervical carcinoma mortality higher among women in Appalachia compared with their counterparts elsewhere in the U.S. For both breast and cervical carcinoma, the average annual death rates (1992-1996) varied by geographic areas within the Appalachian states, but most differences were not significant.

CONCLUSIONS

Analysis of mortality trends in breast and cervical carcinoma may provide guidance for prevention and control activities to reduce premature mortality from these diseases.

Feasibility of a tailored intervention to improve preventive care use in women

BACKGROUND

Women age 50 years and older are in need of multiple preventive health care services. Despite recent improvements in rates of delivery of preventive care services, especially within managed care organizations, substantial numbers of women are still being underscreened. Efforts to improve delivery of preventive care services have often focused on one outstanding service despite the fact that patients often are in need of many services.

METHODS

A total of 893 women age 50 to 55 years were mailed a self-administered survey to identify outstanding preventive health care service needs. Patients in need of three or more outstanding preventive health care services were identified from survey respondents to participate in a feasibility study evaluating a tailored, customized intervention called Tic Tac Health.

RESULTS

Five-hundred ninety-one women returned the survey (67%). Four-hundred forty-eight (76%) women were in need of one or more preventive health services; 92 (16%) were in need of three or more. Twenty-two patients (24%) completed the Tic Tac Health card. The women who completed the card were similar to those who did not.

CONCLUSIONS

Despite documented physician visits, presence of managed care health insurance, and a designated primary care provider, a significant number of women are still in need of multiple preventive health services. An intervention targeting multiple preventive health services was demonstrated to be both feasible and effective. Further evaluation via a randomized controlled trial should be conducted to determine if an intervention like Tic Tac Health would be an effective modality for improving rates of receipt of multiple preventive health care services.

Predictors of stage of adoption for colorectal cancer screening

BACKGROUND

Although colorectal cancer is the third most common cancer in women, little is known about predictors of adherence to screening.

METHODS

A randomly selected sample of 202 predominantly low-income and African-American women were interviewed. Knowledge of, attitudes and beliefs about, and practices related to flexible sigmoidoscopy (FS) screening were assessed.

RESULTS

The majority of participants were in the precontemplation stage of adoption (56%). There were significant differences by stage of adoption for FS beliefs, FS barriers, risk of developing colorectal cancer, worry about getting colorectal cancer, and physician recommendation to get a FS. Predictors of adherence to FS guidelines were perceiving fewer barriers to getting a FS and having a physician recommend a FS.

CONCLUSION

Seventy-two percent of the women in this study were nonadherent to FS screening guidelines. Psychosocial factors play an important role in screening for colorectal cancer. Ways of reducing barriers and increasing physician recommendations should be explored.

Surveillance for uterine abnormalities in tamoxifen-treated breast carcinoma survivors: a community based study

BACKGROUND

Tamoxifen-treated breast carcinoma survivors are at elevated risk of endometrial carcinoma. Whether to recommend annual surveillance for uterine abnormalities in this population is currently under debate.

METHODS

This study was a cross-sectional, community-based investigation of tamoxifen use and the frequency of surveillance for endometrial carcinomas in 541 women with breast carcinoma. Study participants whose breast carcinoma was diagnosed in 1994 were interviewed in 1998. Data were collected from a telephone interview and from a cancer registry record. Tests for uterine abnormalities, based on participant reports of endometrial biopsy and transvaginal ultrasound, were categorized according to frequency. Testing for uterine abnormalities was defined as irregular if women reported tests once every 3 years, on average, and as regular, if they reported annual tests.

RESULTS

Forty-nine percent of respondents were current tamoxifen users, 12% were former tamoxifen users, and 39% reported never taking tamoxifen. Of respondents with a uterus (n = 385), 19% reported irregular and 30% regular testing for uterine abnormalities after their breast carcinoma diagnosis. Respondents more frequently reported transvaginal ultrasound (37%) than endometrial biopsy (29%). Women 65 years of age and older were significantly less likely to report regular surveillance for uterine abnormalities (16%) than those younger than 65 years (35%). Current tamoxifen users more frequently reported regular surveillance (43%) than either former (35%) or never tamoxifen users (15%). Multivariable analyses showed tamoxifen users were more likely to have regular (odds ratio [OR], 9.8; 95% confidence interval [CI], 4.4-21.8) or to have irregular testing for uterine abnormalities (OR, 3.9; 95% CI, 1.9-8.1) compared with women who never used tamoxifen, after adjustment for age, number of recent gynecologic visits, and gynecologic symptoms.

CONCLUSIONS

The results of the current study indicate that half of the breast carcinoma survivors in this population were tested for uterine abnormalities. Although at increased risk, 38% of tamoxifen users never had a test. Clear guidelines need to be established for the type and frequency of testing for uterine abnormalities among tamoxifen-treated breast carcinoma patients.

Direct observation of rates of preventive service delivery in community family practice

BACKGROUND

Data on preventive service delivery in primary care practice have been limited by indirect methods of measurement. This study describes directly observed rates of preventive service delivery during outpatient visits to community family physicians.

METHODS

In a multimethod cross-sectional study, research nurses directly observed consecutive patient visits in the offices of 138 family physicians in Northeast Ohio. Patient eligibility for services recommended by the U.S. Preventive Services Task Force was determined from medical record review. Service delivery was assessed by direct observation of outpatient visits. Rates of delivery of specific preventive services were computed. Global summary measures were calculated for health habit counseling, screening, and immunization services.

RESULTS

Among 4,049 visits by established patients with available medical records, wide variation was observed among rates of different preventive services delivered during well-care visits. During illness visits, rates were uniformly low for all preventive services. Counseling services were delivered at only slightly lower rates during illness visits compared to well visits. Patients were up to date on 55% of screening, 24% of immunization, and 9% of health habit counseling services.

CONCLUSION

Rates of preventive service delivery are low. Illness visits are important opportunities to deliver preventive services, particularly health habit counseling, to patients. Preventive service delivery summary scores are useful in providing a patient population perspective on the delivery of preventive services and in focusing attention on delivery of a comprehensive portfolio of services.

Asian American and Pacific Islander breast and cervical carcinoma screening rates and healthy people 2000 objectives

BACKGROUND

Breast carcinoma is the number one cause of cancer-related mortality among Asian American and Pacific Islander (AAPI) women, and for certain subgroups cervical carcinoma is among the top three causes. Yet AAPI women have the lowest cancer screening and early detection rates of all ethnic groups. The practice of merging AAPI data hides significant variation among AAPI groups, and the groups at highest risk for late presentation of disease become invisible. To the authors' knowledge, this study is the first report of disaggregated national data for breast and cervical carcinoma screening in AAPI subpopulations. The authors used data from the National Health Interview Survey (NHIS 1993 and 1994) and evaluated major socioeconomic and access variables associated with screening practices.

METHODS

Healthy People 2000 (HP2000) criteria were used to evaluate the most recent NHIS screening rates for AAPIs as one group and for six distinct subgroups compared with HP2000 criteria. The sample included 2756 non-Hispanic AAPI and 64,196 non-Hispanic white women age 18 years or older in the 1993 and 1994 NHIS. The effects of socioeconomic and access-to-care indicators on screening were explored.

RESULTS

Breast and cervical carcinoma screening rates for AAPIs were below those for white women and well below national goals and guidelines. Lack of insurance, low income, and lack of a usual source of care had a significantly greater negative impact on AAPIs than on white women, indicating that AAPIs may be more vulnerable to structural barriers to cancer control efforts.

CONCLUSIONS

AAPI women have very low rates of breast and cervical screening, which increases their chances of later stage disease presentation. To reach the Healthy People 2000 objectives, targeted efforts are needed to increase cancer screening among AAPI women overall and specific subgroups in particular.

Mammography use among women as a function of age and patient involvement in decision-making

OBJECTIVE

To assess the extent to which self-reported patient involvement in decision-making for initiation of mammography differs with age.

DESIGN

Data from the 1992 National Health Interview Survey (NHIS) Cancer Control Supplement were evaluated. Prevalences were weighted and variances were adjusted using SUDAAN software to account for the complex, multistage sampling probability design of the NHIS. Logistic regression was used to evaluate the relative likelihood of self-reported involvement in the decision to have a mammogram within the preceding year as a function of age and other covariates.

PARTICIPANTS

Mammography use was assessed among 3,863 NHIS female respondents 40 years of age or older. The analysis of decision-making was restricted to the subgroup of 1,064 women who reported a screening mammogram within the preceding year and who provided information on the other relevant variables.

MEASUREMENTS AND MAIN RESULTS

The probability of reported mammography use within the preceding year declines among older groups of interviewees. Among women with a mammogram in the preceding year, the weighted percentage of women reporting active involvement in the decision (patient decision or decided jointly with a physician) declines from 51% among women 40 to 45 years of age to 19% among those aged 75 years or older. The adjusted odds ratio comparing the likelihood of participating in the decision to have a mammogram for the oldest women, compared with the youngest, was 0.31 (95% confidence interval 0.15 to 0.61).

CONCLUSIONS

Older women are substantially less likely than younger women to report active involvement in the mammography decision-making process. Increased use of screening mammography among older women will require greater promotion by physicians. Other interventions, such as directed educational efforts, may also be needed to increase mammography demand among older women.

Screening for colorectal cancer

Colorectal cancer is the third most commonly diagnosed cancer and the second leading cause of cancer deaths in the United States. Fortunately, both the incidence and mortality associated with the disease have declined during the past 2 decades. This is likely due, at least in part, to improved efforts at screening and more aggressive removal of adenomatous polyps. However, colorectal cancer screening is still generally underutilized. This article reviews the current status and future outlook for colorectal cancer screening, including a discussion of risk factors for the disease, its anatomic distribution, proposed mechanisms of development from adenomatous polyps, rationale for screening, and screening options. Published literature concerning the cost-effectiveness of colorectal cancer screening is also summarized. The article concludes with a discussion of the emerging consensus regarding the importance of and approaches to screening.

Nurse endoscopist training: the next step

Nurses have been successfully performing flexible sigmoidoscopy since the early 1970s. There are numerous studies, in both medical and nursing literature, indicating that nurses can perform this traditional physician role safely and efficiently. Both the American Society of Gastroenterology Endoscopists (ASGE) and Society of Gastroenterology Nurses and Associates (SGNA) have endorsed this practice. Programs appropriate for training the nurse endoscopist, however, have not been defined. Although similarities exist in the literature about how nurses and other nonphysician endoscopists are trained, there are also many discrepancies. If nurses are to take a proactive stance in overseeing nursing practice, objective criteria and clinical competencies need to be established. This is the next step in establishing standard acceptance by the medical community and public.

Colon cancer screening among older women caregivers

Colorectal cancers are common causes of morbidity and mortality among women in the United States. Many of these deaths are unnecessary because of the availability of effective early detection methods. The demands of caregiving may limit older women's participation in screening. The purposes of this exploratory study were to describe the participation in colorectal cancer screening of older women (n = 52; mean age 65 years) who were the primary caregivers for an ill spouse or parent, and to investigate the relationship of the caregiving burden and perceptions of health to participation in recommended colorectal cancer screening tests.

RESULTS

Only 36% of the older women (n = 16) had been screened with both fecal occult blood testing (FOBT) and sigmoidoscopy. A number of women had never participated in colorectal cancer screening: 10 (21%) had never undergone FOBT and 22 (47%) had never undergone sigmoidoscopy. Only 20% (n = 9) had received all of the recommended cancer screening tests: mammogram, Papanicalaou smear, FOBT, and sigmoidoscopy. Those who did not participate in cancer screening with sigmoidoscopy had significantly worse health perceptions than those who did participate. Caregiver burden was not significantly associated with differences in cancer screening participation. Only 14 of these older women felt that they would have a good chance of survival if they received a diagnosis of colon cancer. Further research is needed to investigate strategies to increase participation of older women in colon cancer screening.

Delivery of preventive services to older black patients using neighborhood health centers

OBJECTIVES

Older black patients are at risk for underutilization of preventive services. Our objectives were to assess the delivery of five preventive services in Title 330-funded health centers in low income neighborhoods in Cleveland, Ohio, and to determine the association of health system factors and health status with the delivery of these services.

DESIGN

A cross-sectional study.

SETTING

Four neighborhood health centers in low income neighborhoods of Cleveland, Ohio.

PARTICIPANTS

A total of 683 black men and women, aged 70 and older, who regarded the health center as their primary source of outpatient care.

MEASUREMENTS

Demographic characteristics, independence in basic and instrumental activities of daily living, comorbidity scores, and perceived access were determined by telephone interview. We reviewed charts to determine whether each of five preventive service goals were obtained: influenza vaccination within 1 year; pneumococcal vaccination at any time; mammography within 2 years; Papanicolau screening within 1 year or twice at any time in the past with documentation of normal results; and fecal occult blood testing within 2 years.

RESULTS

The defined goals for influenza vaccination, pneumococcal vaccination, mammography, Papanicolau screening, and fecal occult blood testing were achieved for 59%, 64%, 59%, 51%, and 17% of patients, respectively. Influenza and pneumococcal vaccines were obtained more often in persons with greater comorbidity. Mammography and Papanicolau smear were obtained more often in patients without of ADL or IADL impairments. The four clinical sites varied substantially in the delivery of each preventive service. More frequent office visits were associated with greater delivery of all five preventive services. This relationship persisted in multivariable analyses controlling for health status and clinical site.

CONCLUSIONS

This study shows that Title 330 federally supported neighborhood health center sites providing primary care to older blacks in Cleveland achieved high rates of performance in four of the five recommended preventive services. In addition, preventive services practices were associated with prognostically relevant health status information. The frequency of office visits was related strongly and consistently to the performance of the various preventive services, indicating that more, not fewer, office visits may be necessary to achieve Healthy People 2000 targets.

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.

Social inequalities in perceived health and the use of health services in a southern European urban area

People of lower social class have worse health and less access to health services and preventive care. This article describes social class inequalities in health status and use of services, both curative and preventive, in Barcelona, in a country with a national health service. The cross-sectional study uses information from the 1992 Barcelona Health Interview Survey. Social class was designated using an adaptation of the British Registrar General classification. The study variables measured health status, health services utilization, and preventive practices. Bivariate and multivariate analyses were used. Some 88 percent of men in social class I and 81 percent in class V had very good or good perceived health status. For women these figures were 85.2 and 57.6 percent, respectively. Chronic illness increased with lower social class. There were no social class differences in the frequency of physician visits during the two weeks prior to the interview among people with poor perceived health. Some 60.7 percent of women aged over 29 in social class I had periodic cervical smears, but only 32 percent of those in class V; the corresponding figures for mammography were 37.8 and 11.3 percent. The national health service has advantages in terms of access to health services, but more knowledge about the quality of these services is required. The study findings are sufficient to defend the undertaking of equitable health policies, especially in providing access to preventive care for the entire population.

Demographic predictors of cancer screening among Filipino and Korean immigrants in the United States

BACKGROUND

Little is known about cancer-screening practices of various Asian subgroups, and even less is known about factors that may predict screening in these populations.

DESIGN

Two independent surveys were conducted with 218 Filipino and 229 Korean female immigrants, aged 50 years and older, residing in Los Angeles.

RESULTS

In these convenience samples, 48% of Filipino and 41% of Korean women reported receipt of a Pap smear within the past 2 years; 41% of Filipino and 25% of Korean women reported receipt of a mammogram and a clinical breast exam within the past 2 years; and 25% of Filipino and 38% of Korean women reported colorectal cancer screening (blood stool test within the past 12 months or sigmoidoscopy/colonoscopy within the past 5 years). Only 14% of Filipino and 10% of Korean women were adherent to cancer-screening guidelines for all three sites. These differences in screening rates were statistically significant in multivariate analyses of the combined sample, controlling for all demographic characteristics, including age, percent of lifetime in the United States, education, marital status, health insurance, employment, and ethnicity. The two variables that were most consistently independently associated with adherence to cancer screening in both samples were higher percentage of lifetime spent in the United States and ever having had a checkup when no symptoms were present.

CONCLUSIONS

These two variables-percent of lifetime in the United States and ever having had a checkup when no symptoms were present-can alert a physician that cancer-screening tests may be overdue among Korean and Filipino immigrants in the United States. Future research should identify predictors of cancer screening among other Asian immigrant groups and U.S.-born Asian women to assist in targeting intervention efforts.

Smoking and cancer screening for women ages 42-75: associations in the 1990-1994 National Health Interview Surveys

BACKGROUND

Previous studies have found an association between current smoking and lower rates of mammography and Pap testing. The objective of this study was to investigate the association of smoking status with breast and cervical cancer screening across the 1990-1994 National Health Interview Surveys (NHIS). The NHIS provides a consistent set of independent and dependent variables across several surveys, with data collected by a similar in-person interview methodology from year to year. This report employs more databases than have been used in other analyses that have examined associations between smoking and cancer screening.

METHODS

Data were from the health promotion and cancer control supplements to the 1990-1994 NHIS. The target population was women ages 42-75. Associations were examined between smoking status (never, former, <1 pack/day, >/=1 pack/day) and three screening indicators: ever had a mammogram, mammogram in the past 2 years, and Pap test in the past 3 years. Sample sizes ranged from about 3,000 to over 10,800 depending on the respective NHIS survey and dependent variable. Data analyses were conducted by bivariate and multiple logistic regression.

RESULTS

Women who smoked >/=1 pack of cigarettes per day were significantly less likely to have had mammography screening in all NHIS surveys, compared to women who never smoked. Adjusted odds ratios were 0.63 to 0.74 for ever had a mammogram, and 0.56 to 0.66 for mammography in the past 2 years. Women who smoked >/=1 pack per day also had lower Pap test rates than women who never smoked in 1992-1994 (adjusted odds ratios of 0.51-0.71). Results for lighter smokers were not as consistent. Former smokers often had significantly higher screening rates than never smokers.

CONCLUSIONS

Research still needs to identify reasons for lower screening among women who smoke. Factors to explore include the social networks of smokers and broader health behavior patterns. Clinicians should consider heavier smoking as a marker for risk of not obtaining screening and make assessment of screening status a priority at each visit.

Tailored risk notification for women with a family history of breast cancer

BACKGROUND

Evidence indicates that although first-degree relatives of breast cancer cases are at increased risk of developing the disease themselves, they may be underutilizing screening mammography. Therefore, interventions to increase the use of mammography in this group are urgently needed.

METHODS

A randomized two-group design was used to evaluate an intervention to increase mammography use among women (N = 901) with at least one first-degree relative with breast cancer. A statewide cancer registry was used to obtain a random sample of breast cancer cases who identified eligible relatives. The mailed intervention consisted of personalized risk notification and other theoretically driven materials tailored for high-risk women.

RESULTS

An overall significant intervention effect was observed (8% intervention group advantage) in mammography at post-test. There was an interaction of the intervention with age such that there was no effect among women <50 years of age and a fairly large (20% advantage) effect among women 50+ and 65+. Health insurance, education, and having had a mammogram in the year before baseline assessment were positive predictors of mammography at post-test. Perceived risk, calculated risk, and relationship to index cancer case were not associated with mammography receipt.

CONCLUSION

The intervention was successful in increasing mammography rates among high-risk women 50+ years of age. Further work is needed to determine why it was ineffective among younger women.

Flexible sigmoidoscopy by nurses: state of the art 1999

Although screening flexible sigmoidoscopy is associated with a significant decrease in colorectal cancer mortality, less than 50% of eligible Americans have had a sigmoidoscopy. As the United States population ages, over 50 million Americans will be eligible for colorectal cancer screening with flexible sigmoidoscopy. The projected increase in a population eligible for screening is expected to increase demand for this procedure and may result in overwhelming currently available endoscopic resources. Gastroenterology nurses should actively seek training to perform flexible sigmoidoscopy to accommodate this increased demand. Current barriers to nurse-performed sigmoidoscopy are prohibitions by state Boards of Nursing and lack of procedural reimbursement for nurse endoscopists performing flexible sigmoidoscopy. The lack of research about the effectiveness of this practice is a contributing factor to the hindrances in the development of this nursing role. This review outlines research about the effectiveness of flexible sigmoidoscopy by nurses, legal and reimbursement issues, and details the scope of training programs used by institutions with nurse endoscopists.

Colorectal carcinoma screening attitudes and practices among primary care physicians in counties at extremes of either high or low cancer case-fatality

BACKGROUND

To the authors' knowledge, physician attitudes and reported practices regarding colorectal carcinoma screening have not been studied in areas of highest risk for cancer death.

METHODS

Medicare claims were used to calculate colorectal carcinoma 2-year case-fatality rates for counties with >100 incident cases of colorectal carcinoma between 1991-1993. All 2682 practicing primary care physicians in 20 counties with the lowest case-fatality rates (mean of 29.9%) and 19 counties with the highest case-fatality rates (mean of 47.8%) were surveyed regarding their screening procedures and attitudes.

RESULTS

Among the 972 respondents (36.1%), the reported use of fecal occult blood testing (FOBT) and flexible sigmoidoscopy was similar in the low and high case-fatality counties. However, physicians who practiced in the high case-fatality counties were less likely to be trained in and to perform sigmoidoscopy themselves (37.0% vs. 45.6%; P<0.01). Moreover, practitioners in the high case-fatality counties were more likely than the other physicians to consider or plan enhanced FOBT and sigmoidoscopic screening in the near future. FOBT and sigmoidoscopy screening rates at the county level were associated negatively with cancer incidence rates, case-fatality rates, and metastatic disease rates, suggesting a potentially protective effect.

CONCLUSIONS

Geographically targeted interventions are a potentially cost-effective strategy for focusing additional screening services on the highest risk populations. The primary care clinicians in these high risk areas are logical partners for these interventions by virtue of their high degree of readiness to change their current screening practices.

Race and differences in breast cancer survival in a managed care population

BACKGROUND

African-American women with breast cancer have poorer survival than European-American women. After adjustment for socioeconomic variables, survival differences diminish but do not disappear, possibly because of residual differences in health care access, biology, or behavior. This study compared breast cancer survival in African-American and European-American women with similar health care access.

METHODS

We measured survival in women with breast cancer who are served by a large medical group and a metropolitan Detroit health maintenance organization where screening, diagnosis, treatment, and follow-up are based on standard practices and mammography is a covered benefit. We abstracted data on African-American and European-American women who had been diagnosed with breast cancer from January 1986 through April 1996 (n = 886) and followed these women for survival through April 1997 (137 deaths).

RESULTS

African-American women were diagnosed at a later stage than were European-American women. Median follow-up was 50 months. Five-year survival was 77% for African-American and 84% for European-American women. The crude hazard ratio for African-American women relative to European-American women was 1.6 (95% confidence interval [CI] = 1.1-2.2). Adjusting only for stage, the hazard ratio was 1.3 (95% CI = 0.9-1.9). Adjusting only for sociodemographic factors (age, marital status, and income), the hazard ratio was 1.2 (95% CI = 0.8-1.9). After adjusting for age, marital status, income, and stage, the hazard ratio was 1.0 (95% CI = 0.7-1.5).

CONCLUSION

Among women with similar medical care access since before their diagnoses, we found ethnic differences in stage of breast cancer at diagnosis. Adjustment for this difference and for income, age, and marital status resulted in a negligible effect of race on survival.

Incidental findings in a federally-sponsored cancer screening program

The volume of non-cancer related clinical services and referrals for medical care of women as a consequence of their enrollment in a federally-sponsored breast and cervical cancer screening program was examined. We randomly sampled 100 medical records from among 389 individuals who received cancer screening services through the Connecticut Breast and Cervical Cancer Early Detection Program. Medical record audits tabulated occasions when women were offered or received diagnostic or therapeutic procedures as a by product of their program participation. Breast screening was provided to 100 women and 49 individuals received cervical cancer screening. In addition, 87 percent of the sample were offered or received one or more non-cancer related health services. Physical exams were provided to 86 women, laboratory tests were ordered for 11 individuals and 55 referrals were made to address a myriad of specific medical needs that were uncovered incidental to breast and cervical cancer screening. Among 26 women who did not heed recommendations for follow-up care, cost, inconvenience and beliefs that medical problems were not immediate concerns were cited. Local screening program sponsors should be cognizant that the health care needs and limited resources of some target populations may be substantial. Mechanisms to assure that needed health care is available to individuals should be built and into all categorical health service programs.

Psychological and behavioral factors associated with colorectal cancer screening among Ashkenazim

BACKGROUND

Psychological and behavioral factors related to annual colorectal cancer (CRC) screening were examined in a sample of Ashkenazi Jewish individuals. Identification of factors related to regular CRC screening in this population is important because of the possibility of a heightened incidence of CRC.

METHODS

Eligible participants were 171 Ashkenazi Jewish adults 40 years or older attending an educational program about breast cancer genetics. Compliance with recommended guidelines for digital rectal examination and fecal occult blood test in the past year were dependent measures. Demographic variables, family history of CRC, perceived risk, physician recommendation, and worry about cancer were independent measures.

RESULTS

Digital rectal examinations and fecal occult blood tests had been obtained in the past year by 46 and 31% of the participants, respectively. A logistic regression showed that physician recommendation was related significantly to obtaining digital rectal examinations. Physician recommendation and education were related significantly to obtaining fecal occult blood tests. Although participants with family histories of CRC perceived themselves as being at increased risk of developing CRC, and were more worried about developing colon cancer, they were no more likely to adhere to CRC screening guidelines than those without such histories.

CONCLUSIONS

Overall, compliance with recommended CRC screening was low even among high-risk individuals. Physicians play a key role in motivating people to comply with CRC screening. Physicians need to en courage all asymptomatic patients 50 years and older to be screened for CRC.

Variation in recommendations for cancer screening among primary care physicians in New Mexico

The acceptance of age-appropriate cancer screening as an integral part of primary care has grown among physicians over the past decade. We conducted a mailed survey of all primary care physicians in New Mexico in order to better understand their current cancer screening practices. We found a high rate of self-reported screening, particularly for prostate and colorectal cancer. The screening rates were influenced only slightly by the introduction of evidence-based guidelines, with younger physicians and those with university affiliations more likely to follow recommendations. Female physicians and obstetrician-gynecologists endorsed breast and cervical cancer screening among all age groups and were less likely to follow recommendations for less frequent screening in women as they age. Since a physician's practice beliefs influence his/her attitude toward testing, tailoring education by physician specialty may be more effective than using generic messages in encouraging compliance with the most recent evidence-based guidelines.

Implementation of on-site screening sigmoidoscopy positively influences utilization by primary care providers

BACKGROUND & AIMS

Sigmoidoscopy is an effective screening strategy for colorectal cancer that is not widely used by primary care providers. The aim of this study was to assess the impact of "academic detailing" in the form of an outreach educational seminar combined with implementation of on-site sigmoidoscopy services performed by university-based gastroenterologists on provider compliance.

METHODS

A controlled trial was initiated at 9 urban neighborhood health centers, including 4 intervention and 5 comparison sites. Baseline data on provider attitudes and practice patterns were collected using a validated questionnaire. Outcome measures included a year 1 follow-up survey of provider attitudes and quarterly review of screening sigmoidoscopy referrals using appointment logs to assess utilization.

RESULTS

Overall self-reported compliance rates for screening sigmoidoscopy increased by 36% (baseline, 24%; year 1, 60%) for the intervention group vs. only 7% (baseline, 19%; year 1, 26%) for the comparison group (P = 0. 001). When stratified by site, compliance rates increased at each intervention site (range, 7%-92%) but at only 2 control sites. Use of screening sigmoidoscopy was also significantly greater at the intervention sites (47% vs. 4%; P </= 0.001).

CONCLUSIONS

An outreach educational seminar combined with implementation of on-site sigmoidoscopy services is an effective strategy for enhancing provider utilization of screening sigmoidoscopy.

Screening for breast and cervical cancers: the importance of knowledge and perceived cancer survivability

INTRODUCTION

This study examines the association between recent screening for breast and cervical cancers, knowledge of cancer risk factors, and perceptions of surviving cancer.

METHODS

Data were from the Cancer Control Supplement to the 1992 National Health Interview Survey (NHIS-CCS). The dependent variable combined breast and cervical cancer screening practices into a single composite index. Two independent variables combined women's knowledge about breast and cervical cancers into single indicators--one representing risk factor knowledge, the other representing perceived likelihood of surviving breast and cervical cancers following early detection.

RESULTS

Multivariate analysis showed that recency of screening for both breast and cervical cancers was associated with knowledge of cancer risk factors and perceptions of surviving cancer. Education, household income, and smoking status also were correlates of comprehensive screening. Significant interactions between income and perceived survivability, and between education and perceived survivability suggested that the effects of income and education on comprehensive screening varied with perceptions about surviving cancer.

CONCLUSION

The study suggests that knowledge and attitudinal questions can be combined for two diseases to enhance understanding of who is most likely to be screened comprehensively for breast and cervical cancers. Although national trends show that large percentages of women over age 50 are having mammograms and Pap tests, this progress is not likely to be sustained unless existing barriers are eliminated. Limited knowledge about breast and cervical cancer risk factors and misperceptions about survival from cancer represent two of these barriers.

Analyzing health surveys for cancer-related objectives

Large-scale health surveys conducted by government agencies record information on a large number of health-related variables. We review the use of these data for performing analyses that address cancer-related objectives. After describing the conduct of a large-scale health survey (the third National Health and Nutrition Examination Survey [NHANES III]), we discuss some of the issues involved in analyzing data collected in such a survey. In particular, the use of sample weights in the analysis and the importance of accounting for the complex survey design when estimating standard errors are discussed. Six applications are then presented that involve the following: 1) estimating demographic factors associated with snuff use, 2) estimating the association of type of health insurance with the probability of receiving a digital rectal examination, 3) estimating the association of body iron stores with the probability of later developing cancer, 4) estimating the changing rates of mammography screening in the United States between 1987 and 1992, 5) evaluating smoking and alcohol consumption as risk factors for digestive cancer by use of a population-based, case-control study, and 6) evaluating a randomized community-intervention experiment to encourage smoking cessation. These applications use data from the National Health Interview Survey, the NHANES I Epidemiologic Followup Study, the 1986 National Mortality Followback Survey, and the Community Intervention Trial for Smoking Cessation. The availability of public-use data files is discussed for surveys sponsored by the U.S. government that collect health-related information. We demonstrate that statistical methods and computer software are available for analyzing public-use data files of surveys to address different types of cancer-related objectives.

Breast and cervix cancer screening among multiethnic women: role of age, health, and source of care

OBJECTIVE

The aim of this study was to evaluate the relationships between age, health status, access to care, and breast and cervical cancer screening among multiethnic elderly and nonelderly women.

METHODS

A structured telephone survey of a quota sample of 1,420 New York City women from four Hispanic groups (Columbian, Dominican, Puerto Rican, Ecuadorian) and three black groups (U.S., Caribbean, and Haitian) was performed. Outcome measures included "ever" and "recent" self-reported use of mammography, clinical breast examination (CBE), and Pap smears. Logistic regression models assessed the predictors of screening use.

RESULTS

Having a regular source of care significantly predicted all screening use for both elderly and nonelderly, controlling for ethnicity, sociodemographics, health status, access to care, proportion of life in the United States, and cancer attitudes. Elderly women (>/=65 years) were significantly less likely to have ever had (OR = 0.79, 95% CI 0.65-0. 96) and to have recently had (OR = 0.67, 95% CI 0.57-0.79) Pap smears than younger women, controlling for the other variables; being elderly also tended to be an independent predictor of ever and recent mammography and CBE use. Interestingly, there was a trend for health status to act differently in predicting Pap smear use for the two age groups. For younger women, being in poor health increased the odds of Pap smear screening, while for elderly women, being in good health increased the odds of screening.

CONCLUSIONS

Elderly women reported being screened less than younger women; interactions between health status and age need further exploration.

Low income, race, and the use of mammography

OBJECTIVE

To describe national trends in mammography use by race and income and to test whether higher use of mammography among low-income African American women than low-income white women can be explained by health insurance coverage, usual place of health care, or place of residence.

DATA SOURCES/STUDY SETTING

Data from five years of the National Health Interview Survey spanning the period 1987-1994.

STUDY DESIGN

Trends in the percentage of women 50-64 years of age with a mammogram within the past two years were analyzed by race and income. Data for 1993-1994 were pooled, and with logistic regression analysis, variation in use of recent mammography for low-income women was investigated. Independent variables are age, race, family income, education, health insurance coverage, place of usual source of health care, metropolitan residence, and geographic region.

DATA COLLECTION/EXTRACTION METHODS

The National Health Interview Survey is a cross-sectional national survey conducted by the National Center for Health Statistics. Data are collected through household interviews. [Editor's note: in keeping with HSR policy, the term black is used to conform to its use in the surveys studied. In other references to race, the term African American is used.]

PRINCIPAL FINDINGS

Among women 50-64 years of age use of recent mammograms increased rapidly between 1987 and 1991 for all groups of women, and between 1991 and 1994 the increases slowed. However, increases between 1991 and 1994 have been more rapid among low-income black women than among low-income white women. In 1993-1994, low-income black women were about one-third more likely than low-income white women to report mammography within the past two years. This difference could not be explained by health insurance coverage, usual source of health care, metropolitan status, or region of residence.

CONCLUSIONS

These results, which provide some evidence of success for screening programs targeted to the poor, raise the question of why low-income black women appear to be to more likely than low-income white women to have benefited from recent efforts to promote mammography. Continued evaluation of mammography programs focused on women who are underserved as well as the monitoring of trends and variations in service use by race and income are needed.

Evaluation of ENCOREplus. A community-based breast and cervical cancer screening program

BACKGROUND

Minority women and women with low income levels are significantly less likely to practice appropriate mammography and Pap test screening. ENCOREplus is a health promotion program that provides outreach, education, referral, and other service that facilitate breast and cervical cancer screening for medically underserved women. The program is delivered through a network of community-based nonprofit organizations (YWCA of the U.S.A). The purpose of this study was to assess the effectiveness of ENCOREplus in promoting mammography and Pap test screening among women who were nonadherent to screening guidelines.

METHODS

Baseline data were collected from women participating in the program. Follow-up occurred within six months of baseline to assess whether or not enrollees received recommended screenings. Screening-completion rates were compared to rates from other published intervention studies.

RESULTS

Data from the program's second implementation year show that 27,494 women participated in the ENCOREplus program. Over half the women were racial/ethnic minorities, over 75% reported annual incomes under $15,000, and 49% reported no insurance. Among women 40 and over, 69.7% were nonadherent to ACS mammography screening guidelines at baseline. Among participants 18 and older, 68.9% were nonadherent to Pap test screening guidelines. Of nonadherent participants, 57.8% received mammograms and 36.5% received Pap tests. Both mammography and Pap test screening-completion rates compared favorably with other programs.

CONCLUSION

This study demonstrates that programs implemented through community-based organizations can be successful in increasing mammography and Pap test screening among low-income and minority women.

Predictors of compliance with recommended cervical cancer screening schedule: a population-based study

BACKGROUND

The prevalence of routine cervical cancer screening and compliance with screening schedules are low compared to the Year 2000 objectives. Identifying predictors of routine screening and screening schedule compliance will help achieve these objectives.

METHODS

We analyzed data from probability samples of 1,609 Missouri women responding to both the 1994 Behavioral Risk Factor Surveillance System (BRFSS) and the Missouri Enhanced Survey (ES). We generated prevalence odds ratios to identify predictors of non-compliance to cervical cancer screening guidelines. Also, among a sample of women reporting a reason for last Pap test, we estimated the relative odds of a screening v. diagnostic exam.

RESULTS

In the combined probability sample, compliance with screening schedule was likely among women younger than 50 years of age and women who had either a recent mammography or a clinical breast exam. Being African-American, not experiencing a cost barrier when seeking medical care, having at least a high-school education and health coverage were each associated with an increased compliance with a screening schedule in the combined probability sample. Among women in the combined probability sample, whites, those who experienced no cost barrier to seeking medical care, the non-obese, and those who had a recent mammography were each more likely to have had a screening as opposed to a diagnostic exam.

DISCUSSION

Cancer control and cardiovascular (CVD) prevention programs should consider jointly targeting those at high risk for cervical cancer and CVD because of aging and associated high-risk behavior such as non-compliance with cervical cancer screening, smoking, and obesity. Also, further research is needed to examine whether the increased compliance with cervical cancer screening guidelines among African American women may be in part due to higher occurrence of diagnostic Pap smears.

Compliance with mammography guidelines: physician recommendation and patient adherence

BACKGROUND

Guidelines recommend that women ages 50-75 years receive screening mammography every 1-2 years. We related receipt of physician recommendations for mammography and patient adherence to such recommendations to several patient characteristics.

METHODS

We retrospectively reviewed medical records of 1,111 women ages 50-75 attending three clinics in an urban university medical center. We ascertained overall compliance with mammography guidelines and two components of compliance: receipt of a physician recommendation and adherence to a recommendation. Outcome measures were the proportion of patients demonstrating each type of compliance and adjusted odds ratios, according to several patient-related characteristics.

RESULTS

Overall, 66% of women received a recommendation. Of women receiving a documented recommendation, 75% adhered. Factors showing significant positive associations with receiving a recommendation included being a patient in the general internal medicine clinic, having private insurance, visiting the clinic more often, and having a recent Pap smear. Patient adherence was positively associated with private insurance and Pap smear history, negatively associated with internal medicine, and not associated with visit frequency.

CONCLUSIONS

Patient factors influencing physician mammography recommendations may be different from those associated with patient adherence, except for having private health insurance, which was a predictor of both.

Flexible sigmoidoscopy by paramedical personnel

Screening sigmoidoscopy is associated with a 45% to 80% reduction in colorectal cancer mortality. Although less than 50% of eligible Americans have been screened with flexible sigmoidoscopy (FS), the use of this procedure is rising rapidly. By the year 2000, as many as 10 million screening FS per year could be performed. To accommodate the increased demand, many medical centers have trained paramedical personnel (i.e. physician assistants, nurses, and gastroenterology technicians) to perform FS. However, as a result of the paucity of research about this practice, only physicians receive a professional fee for performing screening FS. Many state Boards of Nursing explicitly prohibit registered nurses (RNs) from performing this procedure. This review outlines research about the effectiveness of paramedical endoscopists, medico-legal and reimbursement issues, and outlines a training program in FS for paramedical personnel.
