Abstract
IMPORTANCE Decisions for older adults (aged ≥65 years) and their clinicians about whether to continue to screen for cancer are not easy. Many older adults who are frail or have limited life expectancy or comorbidities continue to be screened for cancer despite guidelines suggesting they should not; furthermore, many older adults have limited knowledge of the potential harms of continuing to be screened. OBJECTIVE To summarize the patient-reported factors associated with older adults' decisions regarding screening for breast, prostate, colorectal, and cervical cancer. EVIDENCE REVIEW Studies were identified by searching databases from January 2000 to June 2020 and were independently assessed for inclusion by 2 authors. Data extraction and risk of bias assessment were independently conducted by 2 authors, and then all decisions were cross-checked and discussed where necessary. Data analysis was performed from September to December 2020. FINDINGS The search yielded 2475 records, of which 21 unique studies were included. Nine studies were quantitative, 8 were qualitative, and 4 used mixed method designs. Of the 21 studies, 17 were conducted in the US, and 10 of 21 assessed breast cancer screening decisions only. Factors associated with decision-making were synthesized into 5 categories: demographic, health and clinical, psychological, physician, and social and system. Commonly identified factors associated with the decision to undergo screening included personal or family history of cancer, positive screening attitudes, routine or habit, to gain knowledge, friends, and a physician's recommendation. Factors associated with the decision to forgo screening included being older, negative screening attitudes, and desire not to know about cancer. Some factors had varying associations, including insurance coverage, living in a nursing home, prior screening experience, health problems, limited life expectancy, perceived cancer risk, risks of screening, family, and a physician's recommendation to stop. CONCLUSIONS AND RELEVANCE Although guidelines suggest incorporating life expectancy and health status to inform older adults' cancer screening decisions, older adults' ingrained beliefs about screening may run counter to these concepts. Communication strategies are needed that support older adults to make informed cancer screening decisions by addressing underlying screening beliefs in context with their perceived and actual risk of developing cancer.

[PMID: 31753257 DOI: 10.1016/j.amepre.2019.08.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Revised: 08/04/2019] [Accepted: 08/05/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The 2012 national cervical cancer screening guidelines recommended cessation of screening after age 65 years in women with adequate prior screening. In this retrospective cohort study, adherence to these screening exit guidelines was examined. METHODS Women who turned age 66 years in 2012-2013 at Kaiser Permanente Southern California were followed through age 68 years for cervical cancer screening uptake. Adequacy of prior screening was assessed between age 56 and 65 years using electronic medical records. Guideline adherence was determined based on screening pattern between age 66 and 68 years. Patient- and physician-level correlates for guideline adherence were examined using multivariable logistic regression. Data collection and analyses were conducted in 2018. RESULTS A total of 14,778 women were included; 24% did not have adequate prior screening by age 65 years. Among those without adequate prior screening, the proportion screened after age 65 years ranged from 71% (177 of 249) in those whose most recent test was abnormal to 3% (34 of 1,330) in those who did not have any testing in 10 years. Prior screening pattern was the only factor associated with screening after age 65 years. Of those with adequate prior screening, 10% (1,135 of 11,295) continued to receive screening after age 65 years. Frequent office visits and having a male primary care physician were associated with continuing screening after age 65 years. CONCLUSIONS A considerable proportion of women did not have adequate prior screening by age 65 years. Of these, a large proportion did not receive screening after age 65 years, except those who had a recent abnormal screening result. Further research is needed to understand barriers for guideline adherence and rationales for clinical decision making.

Abstract
Primary care providers frequently recommend, administer, or prescribe health care services that are unlikely to benefit their patients. Yet little is known about how to reduce provider overuse behavior. In the absence of a theoretically grounded causal framework, it is difficult to predict the contexts under which different types of interventions to reduce provider overuse will succeed and under which they will fail. In this article, we present a framework based on the theory of planned behavior that is designed to guide overuse research and intervention development. We describe categories of primary care provider beliefs that lead to the formation of intentions to assess the appropriateness of services, and propose factors that may affect whether the presence of assessment intentions results in an appropriate recommendation. Interventions that have been commonly used to address provider overuse behavior are reviewed within the context of the framework.

Abstract
BACKGROUND Little is known about factors associated with willingness to undergo colorectal cancer (CRC) screening for personal or public health benefit among women from diverse race/ethnic groups. OBJECTIVE To evaluate factors associated with willingness to undergo CRC screening for personal and public health benefit among women from diverse race/ethnic groups. METHODS We interviewed women aged 50 to 80 from four racial/ethnic groups from primary care clinics in 2003-2005. We asked about demographics, CRC screening knowledge and history, perceived risk of colon cancer, and about the outcomes of intention to be screened for personal benefit and for public health benefit. RESULTS Of the 492 women who completed the interview, 32 % were White, 16 % were African American, 21 % were Latina and 32 % were Asian. Up-to-date screening was reported by 77 % of women, with similar numbers obtaining fecal occult blood test (FOBT) within 2 years or colonoscopy within 10 years. The majority of women were "likely or very likely" to get FOBT or colonoscopy after learning the benefits and risks. Multivariate models showed that compared to Whites, fewer Asians would undergo colonoscopy (OR = 0.28; 95 % CI: 0.12, 0.63), while more Latinas would undergo colonoscopy (OR = 6.14; 95 % CI: 1.77, 21.34) and obtain regular CRC screening (OR = 4.47; 95 % CI: 1.66, 12.04). The majority would obtain CRC screening even if they would not personally benefit; those who perceived themselves to be at higher than average cancer risk were more likely to participate in CRC screening for public health benefit (OR = 2.32; 95 % CI: 1.32, 4.09). CONCLUSIONS The majority of women are willing to undergo screening for personal benefit. Asians were less likely, and Latinas more likely, to accept colonoscopy. Most are also willing to undergo screening for public health benefit. Self-perceived risk of CRC was the most consistent predictor of willingness and intention to be screened for either personal or public health benefit.

Abstract
OBJECTIVE Less-than-annual cervical cancer screening is now recommended for most US women, raising questions about the need for routine annual bimanual pelvic examinations. Little is known about clinicians' bimanual pelvic examination practices, their beliefs about its importance, or the reasoning underlying its performance in asymptomatic women. STUDY DESIGN We conducted a nationwide survey of US obstetrician-gynecologists. Respondents (n = 521) reported their examination practices and beliefs based on vignettes for asymptomatic women across the lifespan. RESULTS Nearly all obstetrician-gynecologists perform bimanual pelvic examinations in asymptomatic women across the lifespan, although it is viewed as less important for a newly sexually active 18-year-old. Reasons cited as very important included adherence to standard medical practices (45%), patient reassurance (49%), detection of ovarian cancer (47%), and identification of benign uterine (59%) and ovarian (54%) conditions. CONCLUSION Obstetrician-gynecologists perform bimanual pelvic examinations in the vast majority of asymptomatic women, but the importance placed on the examinations and reasons for conducting them vary.

Abstract
Cervical cancer screening algorithms have changed with the introduction of testing for human papillomavirus (HPV) and better understanding of the natural history of HPV. This review was undertaken to present recent developments related to cervical cancer screening, with HPV testing as a focus. Specifically, guidelines now recommend initiating cervical cancer screening at age 21, stopping at age 65 to 70 if previous tests are normal, and screening no more than every 2 to 3 years. Human papillomavirus testing is now incorporated into guidelines for cervical cancer screening in the United States, with the major impact being the lengthening of recommended screening intervals. Primary screening with HPV testing, although not yet approved in the United States, may serve to increase access to care for the millions of underserved women worldwide who bear most of the burden of cervical cancer. Despite clear guidelines from authoritative sources, many clinicians (including midwives) overscreen women. In cervical cancer screening, as in many areas of women's health care, performing tests that are unlikely to result in useful information may lead to harm.

Abstract
OBJECTIVE This study evaluated how well women from diverse race/ethnic groups were able to take a quantitative cancer risk statistic verbally provided to them and report it in a visual format. METHODS Cross-sectional survey was administered in English, Spanish or Chinese, to women aged 50-80 (n=1160), recruited from primary care practices. The survey contained breast, colorectal or cervical cancer questions regarding screening and prevention. Women were told cancer-specific lifetime risk then shown a visual display of risk and asked to indicate the specific lifetime risk. Correct indication of risk was the main outcome. RESULTS Correct responses on icon arrays were 46% for breast, 55% for colon, and 44% for cervical; only 25% correctly responded to a magnifying glass graphic. Compared to Whites, African American and Latina women were significantly less likely to use the icon arrays correctly. Higher education and higher numeracy were associated with correct responses. Lower education was associated with lower numeracy. CONCLUSIONS Race/ethnic differences were associated with women's ability to take a quantitative cancer risk statistic verbally provided to them and report it in a visual format. PRACTICE IMPLICATIONS Systematically considering the complexity of intersecting factors such as race/ethnicity, educational level, poverty, and numeracy in most health communications is needed.

Abstract
UNLABELLED Recently revised US Preventive Services Task Force screening guidelines for colorectal, breast, and prostate cancer contain separate recommendations for persons younger than 75 years and those 75 years or older. Developing an understanding of whether and how patients discontinue screening is important for evaluating the potential benefits and drawbacks of age-delimited screening recommendations as a tool for reducing overdiagnosis rates. Using Surveillance, Epidemiology, and End RESULTS -Medicare data from 1998 to 2007, the authors identified a sample of 32,189 female and 27,669 male fee-for-service Medicare beneficiaries who received 2 consecutive breast or prostate screens, 1 year apart. They then estimated the impact of serious health events, such as heart attacks and strokes, on continuation of screening. Rescreening rates among beneficiaries who did not experience a serious health event were 78% for women and 82% for men. Rescreening rates among beneficiaries who experienced a serious health event were 55% for women and 57% for men. The rate ratios associated with a time-varying indicator for the 2-year period following a serious health event were 0.79 (95% confidence interval: 0.76 to 0.81); P < 0.001) for women and 0.87 (95% confidence interval: 0.85 to 0.89; P < 0.001) for men. Approximately one-third of patients and physicians discontinue or temporarily suspend screening for breast and prostate cancer following serious health events. Findings suggest that not all patients persist with screening until they die.

Abstract
OBJECTIVE To estimate outcomes and costs of surveillance strategies after treatment for high-grade cervical intraepithelial neoplasia (CIN). METHODS A hypothetical cohort of women was evaluated after treatment for CIN 2 or 3 using a Markov model incorporating data from a large study of women treated for CIN, systematic reviews of test accuracy, and individual preferences. Surveillance strategies included initial conventional or liquid-based cytology, human papillomavirus testing, or colposcopy 6 months after treatment, followed by annual or triennial cytology. Estimated outcomes included CIN, cervical cancer, cervical cancer deaths, life expectancy, costs, cost per life-year, and cost per quality-adjusted life-year. RESULTS Conventional cytology at 6 and 12 months, followed by triennial cytology, was least costly. Compared with triennial cytology, annual cytology follow-up reduced expected cervical cancer deaths by 73% to 77% and had an average incremental cost per life-year gained of $69,000 to $81,000. For colposcopy followed by annual cytology, the incremental cost per life-year gained ranged from $70,000 to more than $1 million, depending on risk. Between-strategy differences in mean additional life expectancy per woman were less than 4 days; differences in mean incremental costs per woman were as high as $822. In the cost-utility analysis, colposcopy at 6 months followed by annual cytology had an incremental cost per quality-adjusted life-year of less than $5,500. Human papillomavirus testing or liquid-based cytology added little to no improvement to life-expectancy with higher costs. CONCLUSION Annual conventional cytology surveillance reduced cervical cancers and cancer deaths compared with triennial cytology. For high risk of recurrence, a strategy of colposcopy at 6 months increased life expectancy and quality-adjusted life expectancy. Human papillomavirus testing and liquid-based cytology increased costs, but not effectiveness, compared with traditional approaches.

Abstract
BACKGROUND Recent guidelines recommend longer Pap test intervals. However, physicians and patients may not be adopting these recommendations. OBJECTIVES Identify (1) physician and practice characteristics associated with recommending a less frequent interval, and (2) characteristics associated with women's willingness to adhere to a 3-year interval. RESEARCH DESIGN We used 2 national surveys: (1) a 2006/2007 National Survey of Primary Care Physicians for physician cervical cancer screening practices (N = 1114), and (2) the 2005 Health Information Trends Survey for women's acceptance of longer Pap intervals (N = 2206). MEASURES AND METHODS: Physician recommendation regarding Pap intervals was measured using a clinical vignette involving a 35-year-old with no new sexual partners and 3 consecutive negative Pap tests; associations with independent variables were evaluated with logistic regression. In parallel models, we evaluated women's willingness to follow a 3-year Pap test interval. RESULTS A minority of physicians (32%) have adopted-but more than half of women are willing to adopt-3-year Pap test intervals. In adjusted models, physician factors associated with less frequent screening were: serving a higher proportion of Medicaid patients, white, non-Hispanic race, fewer years since medical school graduation, and US Preventive Services Task Force being very influential in physician clinical practice. Women were more willing to follow a 3-year interval if they were older, but less willing if they had personal or family experiences with cancer or followed an annual Pap test schedule. CONCLUSIONS Many women are accepting of a 3-year interval for Pap tests, although most primary care physicians continue to recommend shorter intervals.
