Tendencia espacio-temporal de clasificación BIRADS sugestiva de malignidad: un análisis nacional de mastografías, 2013-2017 / Spatio-temporal trend of BIRADS classification suggestive of malignancy: a national analysis of mammograms, 2013-2017

Resumen Introducción: Promover la detección de cáncer de mama (CaMa) en mujeres mediante mastografía es una estrategia viable para disminuir los diagnósticos en fases clínicamente avanzadas y la mortalidad. Objetivos: Describir los resultados reportados por estudios de mastografía en mujeres realizados a nivel nacional durante 2013-2017 y analizar la tendencia espaciotemporal de categorías BIRADS (Breast Imaging Reporting and Data System) sugestivas de malignidad por Estado. Método: Diseño analítico longitudinal que incluyó información sobre estudios de mastografía de mujeres según grupo de edad (< 40 e ≥ 40), valoradas en unidades de la Secretaría de Salud, México, durante 2013-2017. Se estimó la frecuencia de categorías según BIRADS, tasa estandarizada sugestiva de malignidad (categorías 4 y 5) en mujeres ≥ 40 años y se utilizó estadística espacial para analizar la tendencia por Estado. Resultados: Se analizaron 3,659,151 mastografías, el 98.5 % en mujeres ≥ 40 años. La tasa sugestiva de malignidad disminuyó de 38.3 (2013) a 31 (2017) por 100 mil mujeres ≥ 40 años; sin embargo, el riesgo de detección aumentó hasta 13 veces en diez Estados. Conclusiones: Aunque el riesgo de detección en categorías sugestivas de malignidad disminuyó a nivel nacional, algunos Estados requieren reforzar la aplicación de programas de detección del CaMa mediante mastografía e incrementar la participación de la población blanco.

Abstract Introduction: Promoting breast cancer (BC) detection in women by means of mammography is a viable strategy to reduce the number of diagnoses at clinically advanced stages and mortality. Objectives: To describe the results reported by mammography studies in women, carried out nationally during 2013-2017, and to analyze the spatiotemporal trend of Breast Imaging Reporting and Data System (BIRADS) categories suggestive of malignancy by State. Method: Longitudinal, analytical design that included information on mammography studies of women according to age group (< 40 and ≥ 40), evaluated in units of the Ministry of Health of Mexico during 2013-2017. The frequency of BIRADS categories and a standardized rate suggestive of malignancy (categories 4 and 5) were estimated in women aged ≥ 40 years, and spatial statistics were used to analyze the trend by State. Results: A total of 3,659,151 mammograms were analyzed, 98.5 % in women aged ≥ 40 years. The malignancy-suggestive rate decreased from 38.3 (2013) to 31 (2017) per 100,000 women aged ≥ 40 years; however, the risk of detection increased up to 13 times in ten States. Conclusions: Although the risk of detection in categories suggestive of malignancy decreased at the national level, some States need to reinforce the application of BC detection programs through mammography and increase the participation of the target population.

Challenges on participation in a cooperative group of childhood renal tumors in Brasil

SUMMARY OBJECTIVE Children with renal tumors included in clinical trials have significantly better outcomes. In Brasil, the enrollment of patients in clinical trials remains challenging. Here we aimed to describe participation accrual in the Brazilian Wilms Tumor Study Group (BWTSG) and to identify barriers to trial registration of children with renal tumors. METHODS We determined the numbers of renal tumor diagnoses in 105 hospital-based cancer registries from 2001-2009. We then compared these totals with the numbers of renal tumor cases registered in the BWTSG from the same hospitals during the same time period. We also invited members of the Brazilian Pediatric Oncology Society to complete a 5-point Likert-type scale questionnaire regarding their opinions of the importance of participation in cooperative group trials. RESULTS The accrual rate of patient participation per hospital varied from 25% to 76%, and was highest in the South region. The accrual rate of hospital participation also varied according to the region (20-31%) and was highest in the Southeast region. For the questionnaire regarding the importance of participation in cooperative groups, the responses showed an agreement of >75% on 10 of the 13 statements. CONCLUSION Our results demonstrated low accrual of participation in a cooperative group trial in Brasil. We identified variations in registration rates according to geographic region and hospital, which may help targeted efforts to increase registration rates. The survey responses demonstrated that colleagues understand the importance of trial participation.

RESUMO OBJETIVO Crianças com tumores renais incluídas em ensaios clínicos apresentam melhora significativa na sobrevida. No entanto, o envolvimento desses pacientes em ensaios clínicos continua sendo um desafio no Brasil. Nosso objetivo neste estudo é descrever a taxa de aderência e adesão no Grupo Cooperativo Brasileiro para tratamento de Tumor de Wilms (GCBTTW) e identificar barreiras na participação ao protocolo. MÉTODOS Identificamos o número de casos de tumores renais diagnosticados em 105 registros hospitalares de câncer no período de 2001 a 2009. O número total desses casos foi então comparado ao número de casos de tumores renais registrados no GCBTTW provenientes das mesmas unidades hospitalares e durante o mesmo período. Os membros da Sociedade Brasileira de Oncologia Pediátrica foram convidados para completar um questionário com escala do tipo likert com o objetivo de conhecer suas opiniões sobre a importância e as dificuldades na participação em ensaios clínicos de grupos cooperativos. RESULTADOS A aderência de pacientes por hospital variou de 25% a 76% e foi maior na região Sul. A adesão da participação do hospital também variou de acordo com a região (20-31%) e foi maior na região Sudeste. Com relação ao questionário referente à importância da participação em grupos cooperativos, as respostas mostraram concordância de mais de 75% em 10 das 13 afirmações. CONCLUSÃO Nossos resultados demonstraram uma baixa participação em grupos cooperativos no Brasil. Houve variações nas taxas de adesão e aderência de acordo com a região geográfica e unidade hospitalar, o que pode auxiliar em futuros esforços para a melhora dessas taxas. As respostas ao questionário demonstraram que os profissionais entendem a importância da participação em grupos cooperativos.

The use of geographical analysis in assessing the impact of patients' home addresses on their participation in outpatient cardiac rehabilitation: a prospective cohort study

PURPOSE@#Geographical analysis is becoming a powerful tool for evaluating the quality of medical services and acquiring fundamental data for medical decision-making. Using geographical analysis, we evaluated the impact of the distance from patients' homes to the hospital on their participation in outpatient cardiac rehabilitation (OCR).@*METHODS@#All patients hospitalized for percutaneous coronary intervention, coronary artery bypass grafting, valvular surgery, congestive heart failure, and aortic diseases were advised to participate in an OCR program after discharge. Using the dataset of our cohort study of OCR from 2004 to 2015 (n = 9,019), we used geographical analysis to investigate the impact of the distance from patients' homes to hospital on their participation in our OCR program.@*RESULTS@#Patients whose road distance from home to hospital was 0-10 km, 10-20 km, and 20-30 km participated more in OCR than those whose road distance was ≧ 30 km (OR 4.34, 95% CI 3.80-4.96; OR 2.98, 95% CI 2.61-3.40; and OR 1.90, 95% CI 1.61-2.23, respectively). Especially in patients with heart failure, the longer the distance, the lesser the participation rate (P < .001).@*CONCLUSIONS@#Using geographical analysis, we successfully evaluated the factors influencing patients' participation in OCR. This illustrates the importance of using geographical analysis in future epidemiological and clinical studies.@*TRIAL REGISTRATION@#UMIN000028435.

Patient participation in hand hygiene among health professionals / Participación del paciente en la higienización de las manos entre profesionales de salud / Participação do paciente na higienização das mãos entre profissionais de saúde

ABSTRACT Objective: To investigate the perception and attitude of health professionals (HPs) about the patient participation in hand hygiene (HH). Method: A cross-sectional study with 150 HPs from a university hospital in Brazil. A descriptive analysis was conducted. Results: Simple hand hygiene was the preferred method of HPs, rather than hand rubbing with alcohol-based solutions. A total of 83.3% of the HPs supported the patient participation in reminding them about HH, but 48% reported that they would feel uncomfortable; 45.3%, comfortable; and 20.7% were familiar with the "Patients for Patient Safety" program. Conclusion: HPs showed limited knowledge about HH, opposing recommendations on the topic. The contradiction between the HPs acceptance and attitude when questioned by the patient regarding HH was revealed, reflecting a lack of knowledge about the WHO program and the need to implement educational practices in health.

Translation, cross-cultural adaptation and validation of the Diabetes Empowerment Scale - Short Form / Tradução, adaptação cultural e validação do Diabetes Empowerment Scale - Short Form

ABSTRACT OBJECTIVE To translate, cross-culturally adapt and validate the Diabetes Empowerment Scale – Short Form for assessment of psychosocial self-efficacy in diabetes care within the Brazilian cultural context. METHODS Assessment of the instrument’s conceptual equivalence, as well as its translation and cross-cultural adaptation were performed following international standards. The Expert Committee’s assessment of the translated version was conducted through a web questionnaire developed and applied via the web tool e-Surv. The cross-culturally adapted version was used for the pre-test, which was carried out via phone call in a group of eleven health care service users diagnosed with type 2 diabetes mellitus. The pre-test results were examined by a group of experts, composed by health care consultants, applied linguists and statisticians, aiming at an adequate version of the instrument, which was subsequently used for test and retest in a sample of 100 users diagnosed with type 2 diabetes mellitus via phone call, their answers being recorded by the web tool e-Surv. Internal consistency and reproducibility of analysis were carried out within the statistical programming environment R. RESULTS Face and content validity were attained and the Brazilian Portuguese version, entitled Escala de Autoeficácia em Diabetes – Versão Curta, was established. The scale had acceptable internal consistency with Cronbach’s alpha of 0.634 (95%CI 0.494– 0.737), while the correlation of the total score in the two periods was considered moderate (0.47). The intraclass correlation coefficient was 0.50. CONCLUSIONS The translated and cross-culturally adapted version of the instrument to spoken Brazilian Portuguese was considered valid and reliable to be used for assessment within the Brazilian population diagnosed with type 2 diabetes mellitus. The use of a web tool (e-Surv) for recording the Expert Committee responses as well as the responses in the validation tests proved to be a reliable, safe and innovative method.

Assessment of Breast Cancer Patients' Knowledge and Decisional Conflict Regarding Tamoxifen Use

Breast cancer is the most common type of female cancer. Tamoxifen, a selective estrogen receptor modulator, is widely used to decrease breast cancer recurrence and mortality among patients. However, it also increases the risk of endometrial cancer. This study aimed to assess knowledge and decisional conflict regarding tamoxifen use. Between June and October 2014, breast cancer patients using tamoxifen were consecutively screened and requested to complete a survey including the EQ-5D, Satisfaction with Decision Scale (SWD), Decisional Conflict Scale (DCS), and a self-developed, 15-item questionnaire measuring tamoxifen-related knowledge. The study sample comprised 299 patients. The mean total knowledge score was 63.4 of a possible 100.0 (range, 13.3-93.3). While 73.9% of the participants knew that tamoxifen reduces the risk of breast cancer recurrence, only 57.9% knew that the drug increases endometrial cancer risk. A higher education level (> or =college) was associated with a higher, total knowledge score (beta = 4.291; P = 0.017). A higher knowledge score was associated with a decreased DCS score (beta = -0.366; P < 0.001). A higher SWD score was also associated with decreased decisional conflict (beta = -0.178; P < 0.001). In conclusion, the breast cancer patients with higher levels of tamoxifen-related knowledge showed lower levels of decisional conflict regarding tamoxifen use. Clinicians should provide the exact information about tamoxifen treatment to patients, based on knowledge assessment results, so as to aid patients' decision-making with minimal conflict.

¿Cuánta información desean recibir y cómo prefieren tomar sus decisiones pacientes con cáncer avanzado atendidos en una Unidad del Programa Nacional de Dolor y Cuidados Paliativos en Chile? / Information disclosure and decision making preferences of patients with advanced cancer in a Pain and Palliative Care Unit in Chile

Information disclosure and decision making process are important steps in advanced cancer patients management; however, there is no research done in this area in Chile. Aims: To know the preferences of patients with advanced cancer related to information disclosure and style of decision making process. Methods: Prospective observational study with patients in the Palliative Care Unit of Sótero del Río Hospital, in Santiago, Chile. The preferences were evaluated with a Disclosure Information and a Decision Making Preferences Questionnaire. Results: 100 patients were recruited, 52% males, average age 63 years; 90% wanted to receive complete information about diagnosis and 89% complete information about prognosis. The preferences related to decision making process style were: 60% shared, 27% passive and 13% active. The expressed satisfaction with the information received was 89% and 87% with the way decisions were actually made. Conclusions: A majority of patients preferred to receive complete information about diagnosis and prognosis and to make shared decisions. The satisfaction with information disclosure and decision making process was very high. The data of this study supports the need of an adequate information disclosure and of exploring the individual preferences of our patients, with the goal of promoting an informed decision making process that respects the preferences of our patients.

Reproductive history and health screening for women and mortality in the Japan Collaborative Cohort Study for Evaluation of Cancer (JACC).

Reproductive history and participation in health screening for women were surveyed among female subjects, and interesting results were obtained in the present analyses. Women who had never experienced pregnancy had significantly increased risks of death from all causes and cerebrovascular disorders compared with those who had experienced 1 or 2 pregnancies. In contrast, women who had experienced 3 or 4 pregnancies had significantly decreased risks of death from all causes, all cancers, rectal cancer, and breast cancer. Among women who had ever undergone mass screening examination for uterine cervical cancer, there were significantly lower risks of death from all causes, all cancers, stomach cancer, uterine cervical cancer, urinary tract cancer, and ischemic heart diseases compared with those who had not had such experience.
