Telehealth and telemedicine in the management of adult patients after hospitalization for COPD exacerbation: a scoping review.

OBJECTIVE: A substantial number of people with COPD suffer from exacerbations, which are defined as an acute worsening of respiratory symptoms. To minimize exacerbations, telehealth has emerged as an alternative to improve clinical management, access to health care, and support for self-management. Our objective was to map the evidence of telehealth/telemedicine for the monitoring of adult COPD patients after hospitalization due to an exacerbation. METHODS: Bibliographic search was carried in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Scopus, Biblioteca Virtual de Saúde/LILACS and Cochrane Library databases to identify articles describing telehealth and telemonitoring strategies in Portuguese, English, or Spanish published by December of 2021. RESULTS: Thirty-nine articles, using the following concepts (number of articles), were included in this review: telehealth (21); telemonitoring (20); telemedicine (17); teleconsultation (5); teleassistance (4); telehomecare and telerehabilitation (3 each); telecommunication and mobile health (2 each); and e-health management, e-coach, telehome, telehealth care and televideo consultation (1 each). All these concepts describe strategies which use telephone and/or video calls for coaching, data monitoring, and health education leading to self-management or self-care, focusing on providing remote integrated home care with or without telemetry devices. CONCLUSIONS: This review demonstrated that telehealth/telemedicine in combination with telemonitoring can be an interesting strategy to benefit COPD patients after discharge from hospitalization for an exacerbation, by improving their quality of life and reducing re-hospitalizations, admissions to emergency services, hospital length of stay, and health care costs.

Arterial hypertension and associated factors: National Health Survey, 2019.

OBJECTIVE: To analyze the factors associated with self-reported arterial hypertension, as well as its prevalence in the Brazilian adult population. METHODS: Data from 88,531 individuals aged 18 years or older who responded to the 2019 National Health Survey were analyzed. The outcome studied was self-reported arterial hypertension. Sociodemographic variables and clinical and lifestyle conditions were considered as exposures. The prevalence ratio (PR), crude and adjusted for sex, age, and schooling was used as a measure of association to verify the factors related to its prevalence, obtained by Poisson regression with robust variance. RESULTS: The prevalence of self-reported arterial hypertension was of 23.9% (95%CI: 23.4-24.4). When adjusting for age, sex, and schooling, the adjusted Prevalence Ratios (APR) were higher among: regular health self-assessment (APR = 1.6; 95%CI: 1.5-1.6) and bad health self-assessment (APR = 1.7; 95%CI: 1.6-1.8); self-reference to heart disease (APR = 1.7; 95%CI: 1.6-1.7), diabetes (APR = 1.7; 95%CI: 1.6-1.8), high cholesterol (APR = 1.6; 95%CI: 1.6-1.7), overweight (APR = 1.4; 95%CI: 1.4-1.5), and obesity (APR = 2.0; 95%CI: 1.9-2.1); high salt intake (APR = 1.1; 95%CI: 1.0-1.1); higher among former smokers (APR = 1.1; 95%CI: 1.1-1.2) and lower among smokers (APR = 0.9; 95%CI: 0.8-0.9); and consumption of ultra-processed foods (APR = 0.9; 95%CI: 0.8-0.9). CONCLUSION: A quarter of the Brazilian adult population claims to have arterial hypertension, more prevalent among women and associated with older age groups, Black, mixed-race, and others, low schooling, high salt intake, former smoking, presence of comorbidities, and worse health self-assessment.

Temporal trends of morbidities, and risk and protective factors for noncommunicable diseases in elderly residents in Brazilian capitals / Tendências temporais de morbidades e fatores de risco e de proteção para doenças crônicas não transmissíveis em pessoas idosas residentes nas capitais brasileiras

ABSTRACT Objective: To analyze the temporal trends of prevalence of morbidities, risk and protection factors for noncommunicable diseases in elderly residents in Brazilian capitals between 2006 and 2021. Methods: A time series study with data from the Surveillance System of Risk and Protective Factors for Chronic Diseases by Telephone Inquiry. The variables analyzed were: high blood pressure, diabetes, smoking, overweight, obesity, consumption of alcoholic beverages, soft drinks, fruits and vegetables, and the practice of physical activity. Prais-Winsten regression and Interrupted Time Series from 2006 to 2014 and 2015 to 2021 were used. Results: From 2006 to 2021, for the total elderly population, there was an increase in diabetes (19.2 to 28.4%), alcohol consumption (2.5 to 3.2%), overweight (52.4 to 60.7%) and obesity (16.8 to 21.8%), and a reduction in the prevalence of smokers (9.4 to 7.4%) and in soft drink consumption (17 to 8.7%). By the interrupted series, between 2015 and 2021, there was stability in the prevalence of diabetes, female smokers, overweight among men, obesity in the total and male population, and soft drink consumption. Conclusion: Over the years, there have been changes and worsening in the indicators analyzed, such as an increase in diabetes, alcohol consumption, overweight, and obesity, which reinforces the importance of continuous monitoring and sustainability programs to promote the health, especially in the context of economic crisis, austerity, and COVID-19 pandemic.

Effectiveness of Telemedicine in Reducing Hospitalizations in Patients Discharged from the Hospital Due to Heart Failure: A Randomized Clinical Trial Protocol

Abstract Fundament: Telemedicine for follow-up in heart failure (HF) patients is effective in reducing hospitalizations, total and cardiovascular mortality. However, few studies were conducted in low and middle income, where lower access to technology and illiteracy could impact the results. Objective: To assess the effectiveness of associating telemedicine strategies, when compared to usual care, in reducing hospitalizations related to HF in patients discharged from the hospital due to HF. Methods: Controlled, randomized, multicenter, parallel-arm clinical trial, with an allocation ratio of 1:1, blinded to outcome evaluation, in which 340 patients who were discharged from public hospitals in Belo Horizonte due to HF will be randomized. Patients will be followed for 6 months and the intervention group will receive, in addition to the usual care, Structured Telephone Support (STS) from a nurse, a doctor, and an educational program. Counseling will be according to a clinical decision tree. The level of significance in the statistical analysis will be 5%. Expected results: Reduction in the number of hospital readmissions and/or in hospitalization time, in addition to developing a software with a clinical decision tree for remote follow-up and patient education about HF adapted to local culture. Conclusions: The intention of this study is to develop a telemedicine strategy and assess whether or not, in addition to the usual care, it is effective in reducing hospitalizations and mortality from HF. If effective, the aforementioned strategy could reduce costs and hospital needs in the Unified Health System (SUS, in Portuguese) for patients with HF. These results will be even more relevant considering the pandemic of COVID-19.

Impact of the COVID-19 pandemic on hospital admissions for cardiovascular diseases in a large Brazilian urban center.

INTRODUCTION: The COVID-19 pandemic has had a great impact on the behavior of individuals and the organization of health systems. This study analyzed the COVID-19 pandemic's effect on public hospitalizations for cardiovascular diseases (CVD) in a large city in Brazil, Belo Horizonte, MG, with approximately 2.5 million inhabitants. METHODS: In a time-series analysis, this study used administrative data from the national "Hospital Information System" from 2010 to February 2020 to estimate the expected number of hospitalizations for CVD by month during the COVID-19 pandemic in Belo Horizonte in 2020 using the Auto-Regressive Integrated Moving Average model. For CVD, this study compared the expected number of hospital admissions, intensive care use, deaths during hospitalization, and mean length of stay with the observed number during the period. RESULTS: There were 6,517 hospitalizations for CVD from March to December 2020, a decrease of 16.3% (95% CI: 4.7-25.3) compared to the projected. The number of intensive care hospitalizations for CVD fell 24.1% (95% CI 13-32.7). The number of deaths also decreased (17.4% [80% CI: 0 - 0.30]), along with the reduction in hospitalizations, as did the length of stay for CVD hospitalizations. These reductions, however, were not significant. CONCLUSIONS: Hospitalizations for CVD were 16.3% lower than expected in a large Brazilian city, possibly due to the fear of getting infected or going to hospitals. Public campaigns informing how to proceed in case of CVD show that prompt urgent attention is essential to mitigate the indirect effects of the pandemic on CVD.

The prevalence ratio (PR), crude and adjusted for sex, age, and schooling was used as a measure of association to verify the factors related to its prevalence, obtained by Poisson regression with robust variance. RESULTS The prevalence of self-reported arterial hypertension was of 23.9% (95%CI: 23.4-24.4). When adjusting for age, sex, and schooling, the adjusted Prevalence Ratios (APR) were higher among: regular health self-assessment (APR = 1.6; 95%CI: 1.5-1.6) and bad health self-assessment (APR = 1.7; 95%CI: 1.6-1.8); self-reference to heart disease (APR = 1.7; 95%CI: 1.6-1.7), diabetes (APR = 1.7; 95%CI: 1.6-1.8), high cholesterol (APR = 1.6; 95%CI: 1.6-1.7), overweight (APR = 1.4; 95%CI: 1.4-1.5), and obesity (APR = 2.0; 95%CI: 1.9-2.1); high salt intake (APR = 1.1; 95%CI: 1.0-1.1); higher among former smokers (APR = 1.1; 95%CI: 1.1-1.2) and lower among smokers (APR = 0.9; 95%CI: 0.8-0.9); and consumption of ultra-processed foods (APR = 0.9; 95%CI: 0.8-0.9). CONCLUSION A quarter of the Brazilian adult population claims to have arterial hypertension, more prevalent among women and associated with older age groups, Black, mixed-race, and others, low schooling, high salt intake, former smoking, presence of comorbidities, and worse health self-assessment.

RESUMO OBJETIVO Analisar os fatores associados à hipertensão arterial autorreferida, bem como sua prevalência, na população de adultos brasileiros. MÉTODOS Foram analisados dados de 88.531 indivíduos de 18 anos ou mais que responderam à Pesquisa Nacional de Saúde de 2019. O desfecho estudado foi a hipertensão arterial autorreferida. Como exposições, foram consideradas variáveis sociodemográficas, condições clínicas e de estilo de vida. Para verificar os fatores associados à prevalência, usou-se como medida de associação a razão de prevalência (RP) bruta e ajustada por sexo, idade e escolaridade, obtidas por meio da Regressão de Poisson com variância robusta. RESULTADOS A prevalência da hipertensão arterial autorreferida foi de 23,9% (IC95% 23,4-24,4). Ao ajustar por idade, sexo e escolaridade, as Razões de Prevalência ajustadas (RPaj) foram mais elevadas entre: auto avaliação de saúde regular (RPaj = 1,6; IC95% 1,5-1,6) e ruim (RPaj = 1,7; IC95% 1,6-1,8); autorreferência a doença do coração (RPaj = 1,7; IC95% 1,6-1,7), diabetes (RPaj = 1,7; IC95% 1,6-1,8), colesterol elevado (RPaj = 1,6; IC95% 1,6-1,7), sobrepeso (RPaj = 1,4; IC95% 1,4-1,5) e obesidade (RPaj = 2,0; IC95% 1,9-2,1); consumo elevado de sal (RPaj = 1,1; IC95% 1,0-1,1); entre ex-fumantes (RPaj = 1,1; IC95% 1,1-1,2) e menor entre fumantes (RPaj = 0,9; IC95% 0,8-0,9) e consumo de alimentos ultraprocessados (RPaj = 0,9; IC95% 0,8-0,9). CONCLUSÃO Um quarto da população adulta brasileira afirma ter hipertensão arterial, de forma mais prevalente entre as mulheres e associada às maiores faixas etárias, cor da pele/raça preta, parda e outras, baixa escolaridade, consumo elevado de sal, ex-tabagismo, presença de comorbidades e pior autoavaliação de saúde.

Impact of the COVID-19 pandemic on hospital admissions for cardiovascular diseases in a large Brazilian urban center

Abstract INTRODUCTION: The COVID-19 pandemic has had a great impact on the behavior of individuals and the organization of health systems. This study analyzed the COVID-19 pandemic's effect on public hospitalizations for cardiovascular diseases (CVD) in a large city in Brazil, Belo Horizonte, MG, with approximately 2.5 million inhabitants. METHODS: In a time-series analysis, this study used administrative data from the national "Hospital Information System" from 2010 to February 2020 to estimate the expected number of hospitalizations for CVD by month during the COVID-19 pandemic in Belo Horizonte in 2020 using the Auto-Regressive Integrated Moving Average model. For CVD, this study compared the expected number of hospital admissions, intensive care use, deaths during hospitalization, and mean length of stay with the observed number during the period. RESULTS: There were 6,517 hospitalizations for CVD from March to December 2020, a decrease of 16.3% (95% CI: 4.7-25.3) compared to the projected. The number of intensive care hospitalizations for CVD fell 24.1% (95% CI 13-32.7). The number of deaths also decreased (17.4% [80% CI: 0 - 0.30]), along with the reduction in hospitalizations, as did the length of stay for CVD hospitalizations. These reductions, however, were not significant. CONCLUSIONS: Hospitalizations for CVD were 16.3% lower than expected in a large Brazilian city, possibly due to the fear of getting infected or going to hospitals. Public campaigns informing how to proceed in case of CVD show that prompt urgent attention is essential to mitigate the indirect effects of the pandemic on CVD.

Frailty in the elderly: screening possibilities in Primary Health Care / Fragilidad en el anciano: posibilidades de rastreo en la Atención Primaria de Salud / Fragilidade no idoso: possibilidades de rastreio na Atenção Primária à Saúde

ABSTRACT Objectives: to evaluate two instruments for screening frailty in the elderly in Primary Health Care. Methods: this is an observational, cross-sectional study, with a quantitative approach, with 396 elderly people. SPSS software helped to perform the statistical analyses. The study used the kappa coefficient and Spearman's correlation. Results: the kappa coefficient between the Clinical-Functional Vulnerability Index 20 and the Edmonton Frailty Scale was 0.496, considered moderate. There was a positive and significant correlation (r = 0.77; p < 0.001) between the frailty conditions and the total score of the two instruments. Conclusions: when this article assessed fragility through the kappa coefficient, both instruments presented positive correlation and agreement. However, the identification of frailty was higher when it used the Edmonton Frailty Scale.
