RESUMO
BACKGROUND: The COVID-19 pandemic represented a great stimulus for the adoption of telehealth and many initiatives in this field have emerged worldwide. However, despite this massive growth, data addressing the effectiveness of telehealth with respect to clinical outcomes remain scarce. OBJECTIVE: The aim of this study was to evaluate the impact of the adoption of a structured multilevel telehealth service on hospital admissions during the acute illness course and the mortality of adult patients with flu syndrome in the context of the COVID-19 pandemic. METHODS: A retrospective cohort study was performed in two Brazilian cities where a public COVID-19 telehealth service (TeleCOVID-MG) was deployed. TeleCOVID-MG was a structured multilevel telehealth service, including (1) first response and risk stratification through a chatbot software or phone call center, (2) teleconsultations with nurses and medical doctors, and (3) a telemonitoring system. For this analysis, we included data of adult patients registered in the Flu Syndrome notification databases who were diagnosed with flu syndrome between June 1, 2020, and May 31, 2021. The exposed group comprised patients with flu syndrome who used TeleCOVID-MG at least once during the illness course and the control group comprised patients who did not use this telehealth service during the respiratory illness course. Sociodemographic characteristics, comorbidities, and clinical outcomes data were extracted from the Brazilian official databases for flu syndrome, Severe Acute Respiratory Syndrome (due to any respiratory virus), and mortality. Models for the clinical outcomes were estimated by logistic regression. RESULTS: The final study population comprised 82,182 adult patients with a valid registry in the Flu Syndrome notification system. When compared to patients who did not use the service (n=67,689, 82.4%), patients supported by TeleCOVID-MG (n=14,493, 17.6%) had a lower chance of hospitalization during the acute respiratory illness course, even after adjusting for sociodemographic characteristics and underlying medical conditions (odds ratio [OR] 0.82, 95% CI 0.71-0.94; P=.005). No difference in mortality was observed between groups (OR 0.99, 95% CI 0.86-1.12; P=.83). CONCLUSIONS: A telehealth service applied on a large scale in a limited-resource region to tackle COVID-19 was related to reduced hospitalizations without increasing the mortality rate. Quality health care using inexpensive and readily available telehealth and digital health tools may be delivered in areas with limited resources and should be considered as a potential and valuable health care strategy. The success of a telehealth initiative relies on a partnership between the involved stakeholders to define the roles and responsibilities; set an alignment between the different modalities and levels of health care; and address the usual drawbacks related to the implementation process, such as infrastructure and accessibility issues.

Introduction: Data addressing the economic aspects of telehealth initiatives are incipient. This study aimed to evaluate the labor costs for running a COVID-19 telehealth system and its potential incremental access to health care service. Methods: From July 2020 to July 2021, data from a Brazilian teleconsultation service were analyzed. Labor costs were estimated by time-driven activity-based costing. A Generalized Reduced Gradient solving method was coded to maximize the mean incremental access rate and two scenarios were considered to compare the teleconsultation with the in-person consultation: (1) only the length of time that patients spent with a clinician in an in-person consultation was accounted and (2) in addition to the medical consultation, nursing screening was accounted. The mean incremental access rate of the teleconsultation service was defined as a maximization objective in the model. Results: Mean labor costs per medical and nursing teleconsultations are Int$ 24 and Int$ 10, based on data analyses from 25,258 patients. Telemonitoring a patient with a daily call for 7 days costs, on average, Int$ 14. COVID-19 teleconsultation service represents, on average, an incremental access to medical consultation rate of 35% to 52% (min 23% max 63%) for the scenarios (1) and (2), respectively, and considering the current consumed budget for this service. Discussion: A COVID-19 telehealth service contributes to increasing access to the health care system without increasing costs. These services can be included in the bundle of care strategies offered in a national public health care system that looks for more sustainable strategies to provide care.

Background: There is a lack of evidence regarding audits or quality analysis of telehealth strategies in clinical practice. Our aim is to develop and implement a methodology for quality assessment of asynchronous teleconsultations. Materials and Methods: A random sample of asynchronous teleconsultations performed by the specialists from the Telehealth Network of Minas Gerais (TNMG), a public telehealth service in Brazil, was selected. The responses were evaluated regarding size, objectivity, quality, ethics, courtesy, and grammar, and received a score for each category: 1 = fair, 2 = moderate, and 3 = good. As each domain has a different importance in rating the overall quality of teleconsultation, each one was assigned a different weight, and a final score was calculated. Results: A total of 576 teleconsultations were assessed. Overall, the scores were good or moderate for all items. Only a few cases were classified as fair. Among medical specialties, pediatrics was the one that proportionally received the highest number of fair classifications, and the item "quality of the answers" was the one with highest number of worse classifications for this specialty. Corrective actions were implemented. With regard to the nonmedical specialties, the majority of the items were classified as good or moderate, and in rare cases some items received the fair rating. Conclusion: The methodology showed to be useful to evaluate the teleconsultation service. We established six domains that we considered important components to be assessed. This assessment was essential to identify the priority areas to receive correct actions. It may be easily replicated in other services worldwide.

Introduction: Early diagnosis and prompt therapy of diabetic retinopathy (DR) are essential to prevent visual loss, but access of the diabetic population to regular fundus examination by an ophthalmologist remains a challenge. Methods: This prospective comparative study, including two referral health centers in the state of Minas Gerais, Southeastern Brazil, assesses applicability and economic viability of fundus photography-based teleophthalmology screening for DR. Results: A total of 2,662 eyes of 1,331 patients were examined at both health centers. Mean age was 57 years, with 836 (62.8%) females. Quality of fundus photographs was acceptable for 2,398 eyes (90.1%). The presence of DR was disclosed in 394 patients (29.6%), with 28 patients (2.1%) presenting evidence of advanced disease (severe nonproliferative or proliferative DR). Economic assessment revealed cost reduction of 28.76 US$ per patient, with a calculated break-even point of 112 exams/month or 1,344 exams/year. Conclusions: For the situation studied under the perspective of public health service, teleophthalmology was viable and cost effective when compared with ordinary ophthalmology examination. In addition, teleophthalmology allowed rapid resolution of repressed demand for fundus examination of diabetic patients locally at the two sites, with early DR diagnoses and referrals. Fundus photography-based teleophthalmology was a viable, effective, and significantly cheaper strategy for the screening of DR.

BACKGROUND: In Brazil, the majority of healthcare resources are concentrated in the largest cities, whereas most communities lack proper healthcare assistance in primary care and have difficulties accessing specialists and diagnostic examinations. Considering this, the Telehealth Network of Minas Gerais (TNMG) was created. It is a public telehealth initiative that provides support to primary healthcare (PHC), performing teleconsultation and telediagnosis (electrocardiogram [ECG], Holter, ambulatory blood pressure monitoring, spirometry, and retinography analysis) mainly for small and remote cities in the state of Minas Gerais, Brazil. PURPOSE: To describe the successful experience of the TNMG in 10 years of activities. METHODS: The TNMG was created in 2005 and supported PHC in 82 cities as a research project and was progressively expanded. A methodology for implementation and maintenance was developed, including quality control. Nowadays it provides support to 750 cities, 88.0% of Minas Gerais state. The examinations performed by the PHC team, with additional basic clinical data, are transmitted through the Internet to the TNMG specialists for remote interpretation. The TNMG teleconsultations system has been used by the PHC team to address written clinical questions to university staff. RESULTS: Until December 2015, 2,464,999 ECGs and 73,698 teleconsultations have already been performed: on average, 2,000 ECGs and 40 teleconsultations per day in 2015. More than 95% of users have declared to be satisfied or very satisfied with the service. A recent cost-benefit analysis of the project showed that for each dollar invested, 6.1 dollars are saved as a consequence of patient referral reduction. CONCLUSIONS: The TNMG is a successful example of a sustainable telehealth service, integrated to primary care centers of remote and small cities. It overcomes geographical barriers to provide specialized healthcare, reducing the number of unnecessary referrals, and contributing to improve the case-resolving capacity and the quality of the PHC.

OBJECTIVE: To analyze the use, effectiveness, and resolubility of teleconsultation services provided to primary care units by the Telehealth Network of Minas Gerais, a public service providing teleconsultation and telediagnosis in cardiology to 821 health care sites. METHODS: This observational retrospective study included teleconsultations carried out between April 2007 and December 2012. Teleconsultations performed from January to May 2010 and January to March 2012 were analyzed regarding the type of query asked by professionals using the service. A survey was carried out to evaluate resolubility and level of satisfaction with teleconsultations. RESULTS: During the study period, 47 689 teleconsultations were carried out. They were most often requested by nurses (53.2%) and physicians (34.3%), and were answered mainly by the following professionals: family physicians (23.3%), dermatologists (19.8%), gynecologists (10,7%), internal medicine physicians (8.8%), pediatricians (6.6%), and nurses (12.2%). The median population in the municipalities that requested teleconsultations was 6 778 (interquartile range [IQR]: 4 425 - 10 805). The median human development index (HDI) was 0.645 (IQR: 0.577 - 0.690). The most frequent queries regarded pharmacological treatment, non-pharmacological treatment, and etiology. Teleconsultations prevented potential referrals in 80% of the cases, and 94% of the health providers reported satisfaction with the service. CONCLUSIONS: The results show that the Telehealth Network of Minas Gerais can help overcome physical barriers in the access to health care and that it may be an important and effective tool for continued health education.

PROBLEM: The Brazilian population lacks equitable access to specialized health care and diagnostic tests, especially in remote municipalities, where health professionals often feel isolated and staff turnover is high. Telehealth has the potential to improve patients' access to specialized health care, but little is known about it in terms of cost-effectiveness, access to services or user satisfaction. APPROACH: In 2005, the State Government of Minas Gerais, Brazil, funded the establishment of the Telehealth Network, intended to connect university hospitals with the state's remote municipal health departments; support professionals in providing tele-assistance; and perform tele-electrocardiography and teleconsultations. The network uses low-cost equipment and has employed various strategies to overcome the barriers to telehealth use. LOCAL SETTING: The Telehealth Network connects specialists in state university hospitals with primary health-care professionals in 608 municipalities of the large state of Minas Gerais, many of them in remote areas. RELEVANT CHANGES: From June 2006 to October 2011, 782,773 electrocardiograms and 30 883 teleconsultations were performed through the network, and 6000 health professionals were trained in its use. Most of these professionals (97%) were satisfied with the system, which was cost-effective, economically viable and averted 81% of potential case referrals to distant centres. LESSONS LEARNT: To succeed, a telehealth service must be part of a collaborative network, meet the real needs of local health professionals, use simple technology and have at least some face-to-face components. If applied to health problems for which care is in high demand, this type of service can be economically viable and can help to improve patient access to specialized health care.

BACKGROUND: Although a great number of teleconsultation services have been developed during the COVID-19 pandemic, studies assessing usability and health care provider satisfaction are still incipient. OBJECTIVE: This study aimed to describe the development, implementation, and expansion of a synchronous teleconsultation service targeting patients with symptoms of COVID-19 in Brazil, as well as to assess its usability and health care professionals' satisfaction. METHODS: This mixed methods study was developed in 5 phases: (1) the identification of components, technical and functional requirements, and system architecture; (2) system and user interface development and validation; (3) pilot-testing in the city of Divinópolis; (4) expansion in the cities of Divinópolis, Teófilo Otoni, and Belo Horizonte for Universidade Federal de Minas Gerais faculty and students; and (5) usability and satisfaction assessment, using Likert-scale and open-ended questions. RESULTS: During pilot development, problems contacting users were solved by introducing standardized SMS text messages, which were sent to users to obtain their feedback and keep track of them. Until April 2022, the expanded system served 31,966 patients in 146,158 teleconsultations. Teleconsultations were initiated through chatbot in 27.7% (40,486/146,158) of cases. Teleconsultation efficiency per city was 93.7% (13,317/14,212) in Teófilo Otoni, 92.4% (11,747/12,713) in Divinópolis, and 98.8% (4981/5041) in Belo Horizonte (university campus), thus avoiding in-person assistance for a great majority of patients. In total, 50 (83%) out of 60 health care professionals assessed the system's usability as satisfactory, despite a few system instability problems. CONCLUSIONS: The system provided updated information about COVID-19 and enabled remote care for thousands of patients, which evidenced the critical role of telemedicine in expanding emergency services capacity during the pandemic. The dynamic nature of the current pandemic required fast planning, implementation, development, and updates in the system. Usability and satisfaction assessment was key to identifying areas for improvement. The experience reported here is expected to inform telemedicine strategies to be implemented in a postpandemic scenario.
RESUMO
Access to specialized care remains unsolved in Brazil. The National Telediagnosis Project was created to expand successful telediagnosis experiences nationwide. The Telehealth Network of Minas Gerais (TNMG) was selected as a reference for tele-electrocardiogram (ECG). We aim to describe the experience of TNMG of developing and implementing the Brazilian National Service of Telediagnosis in Electrocardiography. Implementation planning includes discussion of workflows, standard procedures, responsibility definition for stakeholders, and adaptation of TNMG telediagnosis system. Tele-ECG has been implemented in 79 municipalities in 5 states. In a survey with 152 health professionals, 57% noted that ECG was not available in the local public health system before, 63% indicated tele-ECG service utilization ≥3 days per week, 96% considered the service very useful and 89% were very satisfied with it. In conclusion, the service fills a gap in specialized care in the public system and can improve access to a basic exam in remote and underserved regions.

BACKGROUND: Despite being an important cardiovascular risk factor, hypertension has low control levels worldwide. Computerized clinical decision support systems (CDSSs) might be effective in reducing blood pressure with a potential impact in reducing cardiovascular risk. OBJECTIVE: The goal of the research was to evaluate the feasibility, usability, and utility of a CDSS, TeleHAS (tele-hipertensão arterial sistêmica, or arterial hypertension system), in the care of patients with hypertension in the context of a primary care setting in a middle-income country. METHODS: The TeleHAS app consists of a platform integrating clinical and laboratory data on a particular patient, from which it performs cardiovascular risk calculation and provides evidence-based recommendations derived from Brazilian and international guidelines for the management of hypertension and cardiovascular risk. Ten family physicians from different primary care units in the city of Montes Claros, Brazil, were randomly selected to use the CDSS for the care of hypertensive patients for 6 months. After 3 and 6 months, the feasibility, usability, and utility of the CDSS in the routine care of the health team was evaluated through a standardized questionnaire and semistructured interviews. RESULTS: Throughout the study, clinicians registered 535 patients with hypertension, at an average of 1.24 consultations per patient. Women accounted for 80% (8/10) of participant doctors, median age was 31.5 years (interquartile range 27 to 59 years). As for feasibility, 100% of medical users claimed it was possible to use the app in the primary care setting, and for 80% (8/10) of them it was easy to incorporate its use into the daily routine and home visits. Nevertheless, 70% (7/10) of physicians claimed that the time taken to fill out the CDSS causes significant delays in service. Clinicians evaluated TeleHAS as good (8/10, 80% of users), with easy completion and friendly interface (10/10, 100%) and the potential to improve patients' treatment (10/10, 100%). A total of 90% (9/10) of physicians had access to new knowledge about cardiovascular risk and hypertension through the app recommendations and found it useful to promote prevention and optimize treatment. CONCLUSIONS: In this study, a CDSS developed to assist the management of patients with hypertension was feasible in the context of a primary health care setting in a middle-income country, with good user satisfaction and the potential to improve adherence to evidence-based practices.

BACKGROUND: Mobile phone usage has been rapidly increasing worldwide. mHealth could efficiently deliver high-quality health care, but the evidence supporting its current effectiveness is still mixed. OBJECTIVE: We performed a systematic review of systematic reviews to assess the impact or effectiveness of mobile health (mHealth) interventions in different health conditions and in the processes of health care service delivery. METHODS: We used a common search strategy of five major scientific databases, restricting the search by publication date, language, and parameters in methodology and content. Methodological quality was evaluated using the Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist. RESULTS: The searches resulted in a total of 10,689 articles. Of these, 23 systematic reviews (371 studies; more than 79,665 patients) were included. Seventeen reviews included studies performed in low- and middle-income countries. The studies used diverse mHealth interventions, most frequently text messaging (short message service, SMS) applied to different purposes (reminder, alert, education, motivation, prevention). Ten reviews were rated as low quality (AMSTAR score 0-4), seven were rated as moderate quality (AMSTAR score 5-8), and six were categorized as high quality (AMSTAR score 9-11). A beneficial impact of mHealth was observed in chronic disease management, showing improvement in symptoms and peak flow variability in asthma patients, reducing hospitalizations and improving forced expiratory volume in 1 second; improving chronic pulmonary diseases symptoms; improving heart failure symptoms, reducing deaths and hospitalization; improving glycemic control in diabetes patients; improving blood pressure in hypertensive patients; and reducing weight in overweight and obese patients. Studies also showed a positive impact of SMS reminders in improving attendance rates, with a similar impact to phone call reminders at reduced cost, and improved adherence to tuberculosis and human immunodeficiency virus therapy in some scenarios, with evidence of decrease of viral load. CONCLUSIONS: Although mHealth is growing in popularity, the evidence for efficacy is still limited. In general, the methodological quality of the studies included in the systematic reviews is low. For some fields, its impact is not evident, the results are mixed, or no long-term studies exist. Exceptions include the moderate quality evidence of improvement in asthma patients, attendance rates, and increased smoking abstinence rates. Most studies were performed in high-income countries, implying that mHealth is still at an early stage of development in low-income countries.
RESUMO
BACKGROUND: Telehealth strategies have the potential to improve diabetes care, but there is a lack of evidence about the impact of these strategies in developing countries. Our objective was to analyze the feasibility, usability, and clinical impact of a decision support system (DSS) in Brazilian primary care diabetes patients. MATERIALS AND METHODS: This was a quasi-experimental study that included type 2 diabetes primary care patients >40 years of age. Patients were assessed before (during 6 months) and after the implementation of the DSS application (4 months). The DSS application, used by health professionals, included clinical evaluations and blood glucose measurements and generated specific recommendations based on the data entered. RESULTS: In total, 145 patients were included (mean age, 62.0 ± 9.9 years), 62.1% were female, and 70.0% had been diagnosed with diabetes more than 5 years ago. Overall, there was no decrease in median hemoglobin A1c (HbA1c), from 7.7% (range, 6.5-9.8%) to 7.4% (range, 6.5-9.2%) (P for slope = 0.347). Subgroup analysis showed that patients with an HbA1c level of ≥9% at baseline had a significant reduction in median HbA1c level, from 10.5% (range, 9.9-11.3%) to 10.0% (range, 8.9-10.9%) (P for difference of slope between subgroups = 0.004). The reduction occurred in the first phase of the study, before the DSS use. Healthcare practitioners considered the DSS easy to use (99%) and believed that it provided useful information for patient care (100%). CONCLUSIONS: In this study the improvement of glycemic control before the application in more decompensated patients (HbA1c ≥9%) probably reflects the systematization of diabetes care. The DSS use did not improve the HbA1c level, possibly because of the short follow-up and/or infrequent use by the healthcare practitioners.

AIMS: In Brazil, there are considerable disparities in access to healthcare. The aim of this study was to assess how implementation of a coordinated regional management protocol for patients with ST-elevation myocardial infarction (STEMI) affected quality of care and outcomes in a rural and deprived Brazilian region with considerable social inequalities. METHODS AND RESULTS: The quality of care and outcomes of STEMI was evaluated in two cohorts before (n = 214) and after (n = 143) implementation of the coordinated regional management protocol. Central to this protocol was a tablet-based digital electrocardiogram (ECG) recording in the emergency ambulance that was transmitted for analysis by trained professionals. If the pre-hospital ECG was diagnostic, it triggered a management cascade involving a direct transfer to the regional intervention centre with reperfusion by primary percutaneous coronary intervention (PPCI) or pre-hospital fibrinolysis for anticipated journey times of less than or greater than 2 h, respectively. Following implementation of the protocol, the adjusted medical delay (system delay - transport time) decreased by 40% (95% confidence intervals: -66%, -13%). The proportion of patients who received reperfusion therapy increased from 70.6 to 80.8% (P = 0.045), with increases in treatment with aspirin [94.2-100% (P = 0.003)] and P2Y12 inhibitors [87.5-100% (P < 0.001)]. The odds of in-hospital death showed a non-significant decrease [odds ratio 0.73 (95% confidence intervals: 0.34-1.60)]. CONCLUSION: The implementation of a coordinated regional management protocol for patients with STEMI led to marked improvements in the quality of care in a remote Brazilian region with limited resources.
RESUMO
This observational restrospective study was designed to assess teleconsultations performed by a public telehealth service in Brazil. A satisfaction survey was used to assess the impact on clinical practice. A total of 63,975 teleconsultations were performed, from April 2007 to November 2014. Family physicians (33%) and dermatologists (19%) answered most queries. From January to February 2014 (n=895), the most frequent queries were about etiology (30%) and pharmacological treatment (25%). The satisfaction survey in 2014 (n=571) showed that teleconsultations avoided patient referal in 78%. This study aims to shows the potential of telehealth to provide support to primary care practitioners in remote cities.

Our aim is to describe the evolution of the telediagnostic service of the Telehealth Network of Minas Gerais (TNMG), a public telehealth service in Brazil. It started in 2006 with 82 cities, restricted to electrocardiography analysis. Currently it extends to 772 cities--performing also Holter, ambulatory blood pressure monitoring and retinography analysis--and 48 ambulances in the north of the state, as part of a myocardial infarction system of care. Using low-cost equipment and simple technology, TNMG has employed various strategies to increase telehealth use. The number of ECGs performed by TNMG has progressively increased. It was expected to achieve 2 million in February 2015. The utilization rates were around 90%. It proved to be economically sound, promoting savings of 45M USD for an investment of 10.2M USD. It is currently a regular health service in the state, integrated into the healthcare system. In conclusion, the telehealth model developed in Minas Gerais produced good clinical and economical results.

Our aim is to assess speech therapy teleconsultations performed by the Telehealth Network of Minas Gerais, a public telehealth service that attends 722 cities in Brazil, to demonstrate the importance of the telehealth to support these professionals. In this observational retrospective study, consecutive speech therapy teleconsultations performed by the Telehealth Network of Minas Gerais, Brazil, from February 2011 to May 2014, were analyzed. Socio-demographic characteristics of the cities which requested teleconsultations were assessed, and teleconsultations were analyzed based on the type of query. Throughout the study, 259 valid speech therapy teleconsultations were performed. There were no significant differences in socio-demographic characteristics of municipalities that requested and did not request speech therapy teleconsultations. Speech therapists (65%), nurses (27%) and physicians (5%) requested the highest number of teleconsultations, mostly related to the area of language (47%), oral motor skills (29%), voice (20%), audiology (18%) and dysphagia (10%). In conclusion, teleconsultations demonstrated to be a potential tool for speech therapists working in remote areas.

The Telehealth Network of Minas Gerais (TNMG) is a public telehealth service in Brazil that assists 722 municipalities in the state of Minas Gerais. As a large-scale teleconsultation service, it was important to implement clinical quality control to guarantee the quality of the service. Our aim is to describe the audit of the teleconsultation responses performed by TNMG. A random sample was selected from teleconsultations performed by the specialists from the TNMG between January and February 2014. The responses were evaluated regarding size, objectivity, quality, ethics, courtesy and grammar. A total of 640 teleconsultation responses were assessed, and the mean scores were ≥2.45. Objectivity and quality had the lowest scores in the different specialities. The methodology was useful for evaluating the teleconsultation service and for identifying the areas to improve.

The Telehealth Network of Minas Gerais (TNMG) is a public telehealth service in Brazil that has performed electrocardiogram (ECG) analysis since 2005. From February to March 2014, 28% of ECGs were classified as "emergency" by the primary care tele-health sites. This quasi-experimental study aimed to investigate the reasons behind the high number of emergency ECGs being sent in, the implementation of corrective actions, and an assessment of the impact of these actions. In the 1st phase, primary care units that sent >70% of ECGs as emergency from February to March 2014 were selected. The 2nd phase consisted of the intervention. In the 3rd phase, the proportion of ECGs sent as an emergency during the 1st and 2nd months post intervention were assessed. Of the 63 cities selected during the 1st phase, 50% of the practitioners did not know the proper definition of emergency. After the intervention, 67% of the cities had a significant reduction in the proportion of ECGs sent as an emergency during the 1st month, and 17% had a significant reduction during the 2nd month.

In 722 cities of Minas Gerais (Brazil), primary care patients can have their ECGs remotely interpreted by cardiologists of the Telehealth Network of Minas Gerais (TNMG), a public telehealth service. As of December 2014, more than 1.9 million ECGs were interpreted. This study analyzed the database of all ECGs performed by the TNMG on primary care patients from 2009 to 2013 (n=1,101,993). Structured patient data and the results of automated ECG interpretation by the Glasgow Program are described. Mean patient age is 51 years old, 59% of them are women. The average body mass index is 25.9 kg/m2, with an average increase of 0.15 kg/m2 per civil year. Those patients notably have hypertension (33.2%), family history of coronary artery disease (14.5%), smoking (6.9%), diabetes (5.8%), obesity (5.8%) or Chagas Disease (3.0%). Seventy percent of ECGs are normal. This percentage is higher in women (72.3%) and decreases in average by 7.4 every 10 years of life. There are notably 12% of possible myocardial infarction, 10% of possible left ventricular hypertrophy and 8% of possible supraventricular extra systole.

OBJECTIVE: Knowing the proportion the proportion of normal and abnormal electrocardiograms (ECGs) in primary care patients allows us to estimate the proportion of exams that can be analyzed by the general practitioner with minimal training in ECG interpretation, in addition to being epidemiologically relevant. The objective of this study is to assess the prevalence of normal ECGs in primary care patients. METHODS: All digital ECGs analyzed by the cardiologists of Telehealth Network of Minas Gerais (TNMG) in 2011 were evaluated. TNMG is a public telehealth service that provides support to primary care professionals in 662 municipalities in the state of Minas Gerais, Brazil. RESULTS: During the study period, 290,795 ECGs were analyzed (mean age 51 ± 19 years), 57.6% were normal. This proportion was higher in women (60.1 vs 57.6%, p <0.001) and lower in patients with hypertension (45.8% vs 63.2%, p <0.001) or diabetes (43.3% vs 63.2%, p <0.001). A progressive reduction in the prevalence of normal ECG with increasing age was observed. Among the ECGs of patients under investigation for chest pain, 58.7% showed no abnormalities. CONCLUSION: The prevalence of normal ECGs in primary care patients is higher than 50% and this proportion decreases with age and comorbidities. Most ECGs performed for investigation of chest pain in primary care shows no abnormality.
