Adherence to national guidelines for colorectal, breast, and cervical cancer screenings in Japanese workplaces: a survey-based classification of enterprises' practices into "overscreening," "underscreening," and "guideline-adherence screening".

BACKGROUND: Workplace cancer screening programs are determined as part of an employee's benefits package and health checkups are perceived positively. However, the current status of workplace cancer screening programs in Japan is unavailable. This study aimed to assess the adherence to national guidelines for colorectal, breast, and cervical cancer screenings in the workplace among Japanese enterprises and identify factors associated with excessive or inadequate screenings. METHODS: A cross-sectional study design was employed. Data were obtained from a survey conducted by the "Corporate Action to Promote Cancer Control" between November and December 2022 among registered partner enterprises in Japan. The survey included questions on background characteristics, cancer screening practices, and intervention approaches. The analysis included 432 enterprises that provided complete responses regarding colorectal, breast, and cervical cancer screenings. RESULTS: The guideline-adherence rates for colorectal, breast, and cervical cancer screenings in the workplace were 12.7%, 3.0%, and 8.8%, respectively. Enterprises had lower adherence to screening guidelines than local governments. Colorectal (70.8%) and breast (67.1%) cancer screenings were predominantly categorized as "overscreening" and cervical (60.6%) cancer screening, as "underscreening." Factors such as enterprise scale, health insurance associations, and the number of interventional approaches were significantly associated with increased "overscreening" (101-1000: ß = 0.13, p = 0.01; ≥ 1000: ß = 0.17, p < 0.01; health insurance association: ß = 0.23, p < 0.01; and approaches: ß = 0.42, p < 0.01) and reduced "underscreening" (101-1000: ß = -0.13, p = 0.01; ≥ 1000: ß = -0.17, p < 0.01; health insurance association: ß = -0.18, p < 0.01; and approaches: ß = -0.48, p < 0.01). CONCLUSION: Adherence to national guidelines for colorectal, breast, and cervical cancer screenings in the workplace was suboptimal among Japanese enterprises. Therefore, appropriate cancer screening measures and interventions to ensure guideline adherence and optimization of screening benefits while minimizing potential harms should be expeditiously implemented.

Mechanism of overscreening breakdown by molecular-scale electrode surface morphology in asymmetric ionic liquids.

The interfacial nature of the electric double layer (EDL) assumes that electrode surface morphology significantly impacts the EDL properties. Since molecular-scale roughness modifies the structure of EDL, it is expected to disturb the overscreening effect and alter differential capacitance (DC). In this paper, we present a model that describes EDL near atomically rough electrodes with account for short-range electrostatic correlations. We provide numerical and analytical solutions for the analysis of conditions for the overscreening breakdown and DC shift estimation. Our findings reveal that electrode surface structure leads to DC decrease and can both break or enhance overscreening depending on the relation of surface roughness to electrostatic correlation length and ion size asymmetry.

Comparing Cancer Risk Management between Females with Truncating CHEK2 1100delC versus Missense CHEK2 I157T Variants.

Breast cancer (BC) risks imparted by CHEK2 c.1100delC ("1100delC") germline pathogenic/likely pathogenic variant (GPV) are 20-30%, compared to CHEK2 c.470T>C ("I157T") GPV with <20%, leading to different breast screening recommendations through MRI. We compared cancer risk management (CRM) across these two GPVs. Study participants were adult females with an 1100delC or I157T GPV drawn from the Inherited Cancer Registry (ICARE) across the United States. Cancer history, clinical characteristics, and CRM were compared using chi-squared tests, t-tests, and logistic regression. Of 150 CHEK2 carriers, 40.7% had BC, with a mean age of 50. Comparing 1100delC and I157T GPVs, there were no differences in rates of (1) breast MRI among those with (65.2% versus 55.6% of 23 and 9; p = 0.612) and without (44.0% versus 44.8% of 50 and 29; p = 0.943) BC; (2) risk-reducing mastectomy among those with (50% versus 38.9% of 46 and 15; p = 0.501) and without (13.8% versus 6.5% of 58 and 31; p = 0.296) BC; and (3) risk-reducing salpingo-oophorectomy among those with (24.2% versus 22.2% of 45 and 18; p = 0.852) and without (17.5% versus 16.7% of 57 and 30; p = 0.918) BC. The results suggest over-screening with breast MRI among CHEK2 I157T GPV carriers and possible overuse of risk-reducing surgeries among CHEK2 carriers.

Cervical cancer (over-)screening in Europe: Balancing organised and opportunistic programmes.

AIMS: Cervical cancer (CC) over-screening has been understudied in Europe, yet is relevant for approaching inequalities in screening uptake. Focusing on countries' screening strategies (opportunistic systems versus organised programmes), we assess in which contexts CC over-screening is more prevalent, and which women are more likely to have engaged in cervical cancer screening (CCS) within the past year. METHODS: A two-level (multilevel) design among screening women (N = 80,761) nested in 31 European countries was used to analyse data from the second wave (2013-2015) of the European Health Interview Survey. We focused on over-screening, defined as screening more frequently than the three-yearly screening interval prescribed in the European guidelines - that is, having screened within the past year. RESULTS: Higher levels of over-screening were observed in opportunistic systems compared to systems with organised programmes. In opportunistic systems, women with a higher socioeconomic position had a higher likelihood of being screened within the past year than their socioeconomic counterparts. Moreover, these differences diminished under organised programmes. CONCLUSIONS: Contexts with organised CCS programmes are more efficiently reducing over-screening, and enforcing the European guidelines. We suggest that the physician-patient relationship is an essential pathway for explaining socioeconomic differences in CC (over-)screening and for future interventions.

"It's something I'll do until I die": A qualitative examination into why older women in the U.S. continue screening mammography.

BACKGROUND: Professional guidelines in the U.S. do not recommend routine screening mammography for women ≥75 years with limited life expectancy and/or poor health. Yet, routine mammography remains widely used in older women. We examined older women's experiences, beliefs, and opinions about screening mammography in relation to aging and health. METHODS: We performed thematic analysis of transcribed semi-structured interviews with 19 women who had a recent screening visit at a mammography clinic in New York City (average age: 75 years, 63% Hispanic, 53% ≤high school education). RESULTS: Three main themes emerged: (1) older women typically perceive mammograms as a positive, beneficial, and routine component of care; (2) participation in routine mammography is reinforced by factors at interpersonal, provider, and healthcare system levels; and (3) older women do not endorse discontinuation of screening mammography due to advancing age or poor health, but some may be receptive to reducing screening frequency. Only a few older women reported having discussed mammography cessation or the potential harms of screening with their providers. A few women reported they would insist on receiving mammography even without a provider recommendation. CONCLUSIONS: Older women's positive experiences and views, as well as multilevel and frequently automated cues toward mammography are important drivers of routine screening in older women. These findings suggest a need for synergistic patient, provider, and system level strategies to reduce mammography overuse in older women.

Discontinuing Cancer Screening for Older Adults: a Comparison of Clinician Decision-Making for Breast, Colorectal, and Prostate Cancer Screenings.

BACKGROUND: While guidelines recommend against routine screening for breast, prostate, and colorectal cancers in older adults (65+ years) with <10-year life expectancy, many of these patients continue to be screened. How clinicians consider screening cessation across multiple cancer screening types is unknown. OBJECTIVE: To compare and contrast clinicians' perspectives on discontinuing breast, prostate, and colorectal cancer screenings in older adults. DESIGN: Qualitative, semi-structured interviews. PARTICIPANTS: Primary care clinicians in Maryland (N=30) APPROACH: We conducted semi-structured interviews with individual clinicians. Interviews were recorded, transcribed, and analyzed using standard techniques of qualitative content analysis to identify major themes. KEY RESULTS: Participants were mostly physicians (24/30) and women (16/30). Four major themes highlighted differences in decision-making across cancer screenings: (1) Clinicians reported more often screening beyond guideline-recommended ages for breast and prostate cancers than colorectal cancer; (2) clinicians had different priorities when considering the benefits/harms of each screening; for example, some prioritized continuing colorectal cancer screening due to the test's high efficacy while others prioritized stopping colorectal cancer screening due to high procedural risk; some prioritized continuing prostate cancer screening due to poor outcomes from advanced prostate cancer while others prioritized stopping prostate cancer screening due to high false positive test rates and harms from downstream tests; (3) clinicians discussed harms of prostate and colorectal cancer screening more readily than for breast cancer screening; (4) clinicians perceived more involvement with gastroenterologists in colonoscopy decisions and less involvement from specialists for prostate and breast cancer screening. CONCLUSIONS: Our results highlight the need for more explicit guidance on how to weigh competing considerations in cancer screening (such as test accuracy versus ease of cancer treatment after detection). Recognizing the complexity of the benefit/harms analysis as clinicians consider multiple cancer screenings, future decision support tools, and clinician education materials can specifically address the competing considerations.

Simultaneous Energy Generation and Flow Enhancement (Electroslippage Effect) in Polyelectrolyte Brush Functionalized Nanochannels.

Energy generation through nanofluidics is a topic of great nanotechnological relevance. Here, we conduct all-atom molecular dynamics (MD) simulations of the transport of water and ions in a pressure-driven flow in nanochannels grafted with charged polyelectrolyte (PE) brushes and discover the possibility of simultaneous electrokinetic energy generation and flow enhancement (henceforth denoted as the electroslippage effect). Such PE-brush-functionalized nanochannels have been recently shown to demonstrate an overscreening (OS) effect (characterized by the presence of a greater number of screening counterions within the PE brush layer than needed to screen the PE brush charges), a consequent presence of excess co-ions within the PE brush-free bulk, and a co-ion-driven electroosmotic (EOS) transport in the presence of small to moderate applied axial electric fields. In this study, however, we find that the streaming current, which represents the current generated by the flow-driven downstream advection of the charge imbalance present within the electric double layer (EDL) that screens the PE brush charges, is governed by the migration of the counterions. This stems from the fact that the highest contribution to the overall streaming current arises from the region near the PE brush-water interface (where there is an excess of counterions), while the brush-free bulk yields a hitherto unreported, but small, co-ion-dictated streaming current. This downstream advection of the charge imbalance (and the resultant counterion-driven streaming current) eventually leads to the development of an electric field (streaming electric field) in the direction that is opposite the direction of the counterion-driven streaming current. The streaming current and the streaming electric field interact to generate the electrokinetic energy. Equally important, this streaming electric field induces an EOS transport, which becomes co-ion-driven, due to the presence of excess co-ions in the brush-free bulk. For the case of nanochannels grafted with negatively charged PE brushes, the streaming electric field will be in a direction that is opposite that of the pressure-driven transport, and hence the co-ion (or anion) driven EOS flow will be in the same direction as the pressure-driven transport. On the other hand, for the case of nanochannels grafted with positively charged PE brushes, the streaming electric field will be in the same direction as the pressure-driven flow, and hence the co-ion (or cation) driven EOS flow, will again be in the same direction as the pressure-driven flow. Therefore, whenever there occurs a presence of the OS and the resulting co-ion-driven EOS transport in PE brush grafted nanochannels, regardless of the sign of the charges of the PE brushes, this EOS transport will always aid the pressure-driven transport and will cause the most fascinating increase in the net volume flow rate across the nanochannel cross section, which is the electroslippage effect.

Overscreening, Co-Ion-Dominated Electroosmosis, and Electric Field Strength Mediated Flow Reversal in Polyelectrolyte Brush Functionalized Nanochannels.

Controlling the direction and strength of nanofluidic electrohydrodyanmic transport in the presence of an externally applied electric field is extremely important in a number of nanotechnological applications. Here, we employ all-atom molecular dynamics simulations to discover the possibility of changing the direction of electroosmotic (EOS) liquid flows by merely changing the electric field strength in a nanochannel functionalized with polyelectrolyte (PE) brushes. In exploring this, we have uncovered three facets of nanoconfined PE brush behavior and resulting EOS transport. First, we identify the onset of an overscreening effect: such overscreening refers to the presence of more counterions (Na+) within the brush layer than needed to neutralize the negative brush charges. Accordingly, as a consequence of the overscreening, in the bulk liquid outside the brush layer, there is a greater number of co-ions (Cl-) than counterions in the presence of an added salt (NaCl). Second, this specific ion distribution ensures that the overall EOS flow is along the direction of motion of the co-ions. Such co-ion-dictated EOS transport directly contradicts the notion that EOS flow is always dictated by the motion of the counterions. Finally, for large-enough electric fields, the brush height reduces significantly, causing some of the excess overscreening-inducing counterions to squeeze out of the PE brush layer into the brush-free bulk. As a result, the overscreening effect disappears and the number of co-ions and counterions outside the PE brush layer become similar. Despite that there is an EOS transport, this EOS transport, unlike the standard EOS transport that occurs due to the imbalance of the co-ions and counterions, occurs since a larger residence time of the water molecules in the first solvation shell of the counterions (Na+) ensures a water transport in the direction of motion of the counterions. The net effect is the reversal of the direction of the EOS transport by merely changing the strength of the electric field.

Correlates of premature pap test screening, under 25 years old: analysis of data from the CONSTANCES cohort study.

BACKGROUND: Many countries currently recommend that screening for cervical cancer begin at the age of 25 years. Premature screening (before that age) could lead to unnecessary follow-up examinations and procedures that turn out to be useless. Our objective is to ascertain if the use of particular contraceptive methods are associated with premature screening. METHODS: This cross-sectional study based on the CONSTANCES cohort enabled us to include 4297 women younger than 25 years. The factors associated with premature screening were modeled by logistic regression. Missing data were handled by multiple imputations. The multivariate analyses were adjusted for sex life, social and demographic characteristics, and health status. RESULTS: Nearly half (48.5%) the women younger than 25 years had already undergone premature screening. Women not using contraceptives (aOR 0.3, 95% CI 0.3-0.5) and those using nonmedicalized contraceptives (condom, spermicide, etc.) (aOR 0.5, 95% CI 0.4-0.6) had premature screening less often than women using birth control pills. Higher risks of premature screening were observed in 20-year-old women (aOR 2.7, 95% CI 2.2-3.3) and in those with more than 5 lifetime partners (aOR 2.5, 95% CI 2.0-3.1), compared respectively with women who were younger and those with 5 or fewer lifetime partners. CONCLUSION: Young women using contraceptives that require a doctor's prescription are exposed to premature screening more often than those not using contraception and those with nonmedicalized contraceptives.

Examining Older Adults' Attitudes and Perceptions of Cancer Screening and Overscreening: A Qualitative Study.

INTRODUCTION/OBJECTIVES: Screening guidelines for breast, cervical, and colorectal cancer (CRC) are less clear for older adults due to the potential harms that may result from screening. Understanding older adults' attitudes and perceptions, especially racial/ethnic minority and underserved adults, of cancer screening can help health care providers determine how best to communicate with older adults about cancer screening and screening cessation. The objective of this study was to determine how older adults primarily from minority/underserved backgrounds perceive cancer screening and overscreening. METHODS: Four focus groups (n = 39) were conducted with adults (>=65 years of age) in 3 community settings in south-central Pennsylvania. Two focus groups were conducted in Spanish and translated to English upon transcription. Focus group data was managed and analyzed using QSR NVivo 12. Inductive thematic analysis was used to analyze the data where themes emerged following the coding process. RESULTS: The focus group participants had an average age of 74 years and were primarily female (74%) and Hispanic (69%), with 69% reporting having less than a high school degree. Four key themes were identified from the focus groups: (1) importance of tailored and targeted education/information; (2) impact of physician/patient communication; (3) impact of barriers and facilitators to screening on cancer screening cessation; and (4) awareness of importance of screening. Participants were more likely to be agreeable to screening cessation if they received specific information regarding their health status and previous medical history from their physician as to why screening should be stopped and told by their physician that the screening decision is up to them. CONCLUSIONS: Older adults prefer individualized information from their physician in order to justify screening cessation but are against incorporating life expectancy into the discussion. Future research should focus on developing interventions to test the effectiveness of culturally tailored screening cessation messages for older adults.

A Strategy to Prepare Primary Care Clinicians for Discussing Stopping Cancer Screening With Adults Older Than 75 Years.

BACKGROUND AND OBJECTIVES: Adults older than 75 years are overscreened for cancer, especially those with less than 10-year life expectancy. This study aimed to learn the effects of providing primary care providers (PCPs) with scripts for discussing stopping mammography and colorectal cancer (CRC) screening and with information on patient's 10-year life expectancy on their patients' intentions to be screened for these cancers. RESEARCH DESIGN AND METHODS: Patient participants, identified via PCP appointment logs, completed a questionnaire pre- and postvisit. Primary care providers were given scripts for discussing stopping screening and information on patient's 10-year life expectancy before these visits. Primary care providers completed a questionnaire at the end of the study. Patients and PCPs were asked about discussing stopping cancer screening and patient life expectancy. Patient screening intentions (1-15 Likert scale; lower scores suggest lower intentions) were compared pre- and postvisit using the Wilcoxon signed-rank test. RESULTS: Ninety patients older than 75 years (47% of eligible patients reached by phone) from 45 PCPs participated. Patient mean age was 80.0 years (SD = 2.9), 43 (48%) were female, and mean life expectancy was 9.7 years (SD = 2.4). Thirty-seven PCPs (12 community-based) completed a questionnaire. Primary care providers found the scripts helpful (32 [89%]) and thought they would use them frequently (29 [81%]). Primary care providers also found patient life expectancy information helpful (35 [97%]). However, only 8 PCPs (22%) reported feeling comfortable discussing patient life expectancy. Patients' intentions to undergo CRC screening (9.0 [SD = 5.3] to 6.5 [SD = 6.0], p < .0001) and mammography screening (12.9 [SD = 3.0] to 11.7 [SD = 4.9], p = .08) decreased from pre- to postvisit (significantly for CRC). Sixty-three percent of patients (54/86) were interested in discussing life expectancy with their PCP previsit and 56% (47/84) postvisit. DISCUSSION AND IMPLICATIONS: PCPs found scripts for discussing stopping cancer screening and information on patient life expectancy helpful. Possibly, as a result, their patients older than 75 years had lower intentions of being screened for CRC. CLINICAL TRIALS REGISTRATION NUMBER: NCT03480282.

Unpacking the complexities of de-implementing inappropriate health interventions.

De-implementing inappropriate health interventions is essential for minimizing patient harm, maximizing efficient use of resources, and improving population health. Research on de-implementation has expanded in recent years as it cuts across types of interventions, patient populations, health conditions, and delivery settings. This commentary explores unique aspects of de-implementing inappropriate interventions that differentiate it from implementing evidence-based interventions, including multi-level factors, types of action, strategies for de-implementation, outcomes, and unintended negative consequences. We highlight opportunities to continue to advance research on the de-implementation of inappropriate interventions in health care and public health.

[Interval between two smear tests for cervical cancer screening and characteristics of women with a short interval: Study in the department of Isère]. / Délai entre deux frottis de dépistage du cancer du col utérin et caractéristiques des femmes présentant un délai court : étude dans le département de l'Isère.

AIMS: In France, guidelines for cervical cancer screening recommend that women between the ages of 25-65 have a smear test performed once every three years. However, some women are screened significantly more frequently. In this study, we used a data-driven approach as opposed to a traditional hypothesis-driven approach to characterise the population of women who are screened more frequently than advised. METHODS: Data came from an organised cervical cancer screening programme of a French department in the Alps (Isère). We retrospectively selected women aged between 25 to 65 years old who had at least two smear tests during the follow up period (2011-2015). We used a data-driven clustering approach to compare the population of over-screened women with other populations. We then performed a descriptive analysis of the over-screened population using univariate (Chi2 test) and multivariate (logistic regression) methods. RESULTS: A total of 10,000 patients were randomly chosen from a population of 54,073. In our univariate analysis, women in the over-screened population were significantly younger, participated less in organised screening, were more likely to be followed by a gynaecologist and had more smear test results showing inflammation than the other populations. Patient location (urban v.s. rural area) was not significant for this population. The multivariate analysis confirmed these results. CONCLUSION: This data-driven approach based on an unsupervised learning method enables us to more accurately characterise the over-screened population. These data invite to improve communication with the youngest women and the gynecologists to recall the benefit of an interval between two normal smears complying with the recommendations. This approach could help to improve the prevention and have a real impact on this Public Health issue.

Public health implications of overscreening for carotid artery stenosis, prediabetes, and thyroid cancer.

BACKGROUND: Overscreening occurs when people without symptoms undergo tests for diseases and the results will not improve their health. In this commentary, we examine three examples of how campaigns to screen and treat specific vascular, metabolic, and oncologic diseases in asymptomatic individuals have produced substantial overdiagnosis and may well have contributed to more harm than good. These conditions were chosen because they may not be as well known as other cases such as screening for breast or prostate cancer. MAIN TEXT: Screening for carotid artery stenosis can be a lucrative business using portable equipment and mobile vans. While this fatty buildup of plaque in the arteries of the neck is one risk factor for ischemic stroke, current evidence does not suggest that performing carotid dopplers to screen for CAS reduces the incidence of stroke or provide long-term benefits. After a positive screening, the follow-up procedures can lead to heart attacks, bleeding, strokes, and even death. Similarly, many organizations have launched campaigns for "prediabetes awareness." Screening for prediabetes with a blood sugar test does not decrease mortality or cardiovascular events. Identifying people with prediabetes could lead to psychological stress and starting medication that may have significant side effects. Finally, palpating people's necks or examining them with ultrasounds for thyroid cancer is common in many countries but ineffective in reducing mortality. Deadly forms of thyroid cancer are rare, and the overall 5-year survival rate is excellent. Interventions from treatment for more prevalent, less aggressive forms of thyroid cancer can lead to surgical complications, radiation side effects, or require lifelong thyroid replacement therapy. CONCLUSIONS: Screening for carotid artery stenosis, prediabetes, and thyroid cancer in an asymptomatic population can result in unnecessary, harmful, and costly care. Systemic challenges to lowering overscreening include lack of clinician awareness, examination of conflicts of interests, perverse financial incentives, and communication with the general public.

Ending Cervical Cancer Screening in Low-Risk Women After Age 65: Understanding Barriers to Adherence With Evidence-Based Guidelines Among Primary Care Providers.

BACKGROUND: Current evidence-based cervical cancer testing guidelines recommend that screening of low-risk women ceases after age 65. Despite this, research suggests that continued testing by primary care providers remains common and represents unnecessary patient discomfort, cost, and consumption of valuable primary care resources. OBJECTIVE: To understand why primary care providers might knowingly ignore consensus evidence-based screening guidelines for cervical cancer in low-risk women of this age-group and to identify barriers to adherence with best practice recommendations. METHODS: A survey tool to identify barriers to adherence with current guidelines for cervical cancer screening in low-risk women older than age 65 was mailed to 4929 randomly selected primary care providers throughout California. Providers were asked to indicate the predominant reason(s) they might knowingly continue cervical cancer screening in women older than 65 years, despite evidence-based recommendations to the contrary. RESULTS: Qualified surveys were received from 1259 (25.5%) of those surveyed, representing primary care providers of all types, practicing in areas of vastly different demographics. Despite published reassurance to the contrary, many providers retain fear that discontinuation of testing in low-risk women after age 65 may result in missed invasive cervical cancer. Even among health-care providers who agree that cessation of screening is safe, other circumstances prompt their recommendation to continue cervical screening. CONCLUSION: Although the data from this study suggest areas of policy intervention to lessen unnecessary cervical cancer screening, the broader implication is that advancement of evidence-based medicine will be of little value in improving the quality and cost of health care if barriers to guideline adherence are poorly understood and addressed.

Excess cervical cancer screening smears: Any benefit? A retrospective cohort in Alsace, France.

Objectives Although cervical cancer screening guidelines in France recommend a smear test every three years, many physicians order more regular screening. We aimed to assess the benefits or harms of shorter intervals between screenings, both for women and public health. Methods For a retrospective cohort of women aged 25-65 who had two normal smears and at least one additional smear, data were sourced from a regionally organized cervical cancer screening programme in France, with follow-up for nine years. Based on the interval between the second and third smear, two groups were formed; the first comprised overscreened women (interval <24 months), and the second of 'correctly' screened women (interval between 24 and 42 months). The primary outcome was cervical intraepithelial neoplasia 2 or worse (CIN2+); secondary outcomes were cervical cancers and CIN1 lesions. Results Among 63,821 women, CIN2+ incidence rate per 10,000 women per year was 14.5 for 40,350 overscreened women, and 11.5 for 23,471 correctly screened women. Age-adjusted relative risk was 1.22[1.02; 1.46]. We found no significant difference for cancer (RR = 1.39; 95%CI = [0.60; 3.61]), but did find additional CIN1 in the overscreened group (RR = 2.09; 95%CI = [1.76; 2.51]). Conclusions A shorter interval between smears has a low benefit for CIN2+ lesion detection, which may not help avoid cancer. The excess number of CIN1 detected by overscreening may cause needless risk and excess costs due to overtreatment.

¿Overscreening o prevención a escala humana? Tamizaje excesivo / Sobrerrastreamento ou prevenção em uma escala humana? Excesso de rastreamento / Overscreening or prevention in a human scale? Excessive screening

Cuando se aplica un método de cribado o tamizaje de modo excesivo, abusivo o innecesario los daños provocados pueden superar a los beneficios. Para desarrollar el concepto de tamizaje excesivo, fueron consideradas algunas categorías: tamizaje innecesario, sin indicación médica, inducido, obligatorio, y por frecuencia inadecuada. Existen sesgos de interpretación que no permiten determinar de forma objetiva el balance daño beneficio de los programas de tamizaje relacionados al exceso de diagnóstico. Evitar el daño producido por tamizajes excesivos (overscreening) requiere llevar recomendaciones y pautas genéricas al terreno de la práctica clínica con casos particulares. La prevención cuaternaria, fundada conceptualmente en los cuidados de salud centrados en la persona, permite considerar las creencias, inquietudes, opciones individuales, haciendo posible llevar a la prevención a una escala humana.

Quando um método de rastreio é aplicado de forma excessiva, desnecessária ou abusiva, os danos podem superar os benefícios. Para desenvolver o conceito de excesso de rastreamento, foram consideradas algumas categorias: rastreamento desnecessário, sem indicação médica, induzido, obrigatório, e por frequência inadequada. Existem vieses de interpretação que não permitem determinar objetivamente o balanço dos danos e benefícios dos programas de rastreamento relacionados ao excesso de diagnósticos. Para se evitar danos causados por excesso de rastreamento (overscreening) é necessário se deslocar do campo das recomendações e pautas genéricas para o terreno da prática clínica, com casos particulares. A prevenção quaternária, fundamentada conceitualmente nos cuidados de saúde centrados na pessoa, permite considerar as crenças, interesses, opções individuais, tornando possível levar a prevenção a uma escala humana.

When screening is applied in an excessive, unnecessary or abusive manner, the damage may outweigh the benefits. In order do develop the concept of excessive screening some categories were considered: unnecessary screening, screening without medical indication, induced screening, mandatory screening, and inadequate frequency screening. There are biases of interpretation that do not allow objectively determining the balance of harms and benefits of screening programmes related to overdiagnosis. To prevent damage from excessive screening (overscreening) it is necessary to move from the domain of generic recommendations and guidelines to the clinical practice ground of individual cases. The quaternary prevention, conceptually grounded in person-centred health care, comprises the beliefs, interests, and individual options, making it possible to lead prevention to a human scale.
