Brazil’s public health system serves most of the population, but 25 percent of citizens rely on private health insurance. The National Regulatory Agency for Private Health Insurance and Plans (ANS) regulates private medicine reimbursements, which diverge from the public sector threshold. In 2022, the National Committee for Health Technology Incorporation (CONITEC) set a willingness-to-pay benchmark of BRL40,000 (USD8,215) per quality-adjusted life-year. The ANS has no such benchmark, highlighting a pivotal gap in economic evaluations for private health care.

This quantitative study investigated the Incremental cost-effectiveness ratios (ICER) for reimbursed medicines in Brazil’s private health sector, comparing them with CONITEC’s benchmarks and international thresholds. Data were extracted from industry reimbursement submissions to the ANS and analyzed for statistical disparity and policy implications.

Preliminary findings found an ICER peak of BRL619,900 (USD127,220) per quality-adjusted life-year for talazoparib, which is used to treat certain advanced breast cancers. This contrasted sharply with CONITEC’s established threshold, indicating a critical need to evaluate ANS policies.

Early results indicate that the ICERs for some medicines surpass CONITEC’s willingness-to-pay limit, suggesting that the ANS should consider establishing a defined cost-effectiveness threshold. This is imperative to harmonize with global standards and maintain sustainable health financing.

Despite medical advancements, endocarditis still results in high mortality rates. Surgery, while often essential, elevates the risk of hyperinflammation, sepsis, and cytokine release. The use of a cytokine filter to prevent this remains controversial. This study reviewed existing literature to assess the efficacy of cytokine filters and to support its integration into supplementary health services.

An exhaustive search of the MEDLINE, Cochrane Library, Embase, LILACS, and CytoSorbents Corporation databases was conducted to identify relevant meta-analyses and systematic reviews. The study focused on randomized controlled trials and case series studies assessing the efficacy of cytokine filtration. Key variables considered were the duration of antibiotic treatment, severity of endocarditis, and surgical treatment rationale. These factors were crucial for evaluating clinical outcomes and patient survival after surgery.

The systematic reviews yielded mixed outcomes. Two found no benefits for hemoadsorption, while one found that it reduced mortality rates and intensive care unit stays based on observational studies. Randomized controlled trials, however, showed no significant impact for cytokine filters on mortality rates or postoperative hemodynamic parameters. In contrast, case series studies reported potential benefits, but these results were confounded by biases in patient allocation and failure to account for critical variables like antibiotic treatment duration, case severity, and surgical rationale. These discrepancies highlight the complexity of evaluating the effectiveness of cytokine filtration in surgical settings.

Randomized and non-randomized controlled trials on the role of cytokine filters in cardiac surgery for endocarditis reported contradictory findings. Only case series studies suggested benefits from cytokine filters, necessitating further high quality research before recommending their widespread use. Understanding the implications of these results is essential, underscoring the need for more rigorous studies to resolve these inconsistencies.

Informed healthcare policies in Brazil rely on robust health technology assessment (HTA), especially for conditions like non-small cell lung cancer (NSCLC). We present an efficiency frontier analysis to evaluate NSCLC treatments that correlates annual treatment costs with clinical outcomes, offering a systematic approach to enhance decision-making in the Brazilian healthcare context.

This quantitative study analyzed NSCLC drug costs within the Brazilian healthcare system and the clinical efficacy data of pivotal studies. The data were analyzed using Python and R software. The dataset comprised drug costs and hazard ratios for overall survival. After data preparation, which involved normalization and outlier management, we constructed an efficiency frontier by ranking drugs based on cost and effectiveness. A linear regression model was then developed to extrapolate this frontier, deriving a formula that predicts treatment costs for specified improvements in overall survival.

The analysis delineated an efficiency frontier and revealed cost-effective NSCLC treatments in Brazil. The following linear regression equation was derived: overall survival = (1.033551 − 0.000003) × treatment cost (USD). This allows for the estimation of appropriate treatment costs for new therapies based on their expected clinical outcomes. This initial model provides a foundation for estimating the economic impact of new treatments.

This preliminary efficiency frontier analysis offers a novel perspective for evaluating NSCLC treatment strategies in Brazil to support sustainable healthcare policy decisions. The model is subject to limitations due to the absence of a systematic literature review. However, it represents an initial step towards a more comprehensive HTA framework. Further research should refine the model by including systematic data collection and analysis.

In Brazil, equitable access to medications is critical. There are significant pricing disparities between the National Health System and private health care, which are influenced by the National Committee for Health Technology Incorporation (CONITEC) and Law 14.307. This study investigated these disparities, with aim of proposing strategies for equitable access and sustainability in health care.

This analysis compared prices between the public and private sectors for trastuzumab and adalimumab. Public sector prices were obtained from the Health Prices Database (HPD) and private sector prices were obtained from the Unimed National Table of Materials and Medications (TNUMM), as of May 2023. The study evaluated the extent of pricing discrepancies, considering Drug Market Regulation Chamber ceiling prices and industry discounts.

The cost of the trastuzumab biosimilar, KANJINTI® (Amgen Inc.), was BRL15.79 (USD3.24) per mg in the private sector, compared with BRL4.50 (USD0.92) per mg in the public sector (a 250% difference). The original version of adalimumab, HUMIRA® (AbbVie), was priced at BRL5,450.38 (USD1,120.53) in the TNUMM versus BRL2,445.46 (USD502.33) in the HPD (a 123% difference). The adalimumab biosimilar, HYRIMOZ® (Sandoz Inc.), was priced at BRL7,723.99 (USD1,586.87) in the TNUMM compared with BRL2,449.19 (USD503.05) in the HPD (a 215% price discrepancy).

The study highlights significant disparities in drug pricing between Brazil’s public and private healthcare sectors. These disparities affect the financial sustainability of private health entities and elevate costs for consumers, potentially increasing reliance on the National Health System. Policy revisions, price parity strategies, and further studies are vital for a sustainable healthcare system.

Most drugs have data only from clinical trials focused on a specific population at the time of first registration, so their indications for use are restricted to this population. In Brazil, the prices of new drugs for clinical conditions with no therapeutic alternatives are relatively high. When these drugs expand to other indications their prices are not reviewed, which can have a major financial impact. This study aimed to evaluate the financial impact of expanding the indication for trastuzumab deruxtecan.

We calculated the annual cost to treat all Brazilian patients with the indications listed for trastuzumab deruxtecan at first registration, and then all additional indications. Populations were estimated from epidemiological data from National Committee for Health Technology Incorporation reimbursement documents and a clinical trial comparing trastuzumab deruxtecan with trastuzumab emtansine. Costs were calculated using the ANVISA Câmara de Regulação do Mercado de Medicamentos price value and a patient weight of 70 kg.

In January 2022, trastuzumab deruxtecan was introduced in Brazil for patients with human epidermal growth factor receptor (HER2) positive metastatic or unresectable breast cancer who had received two or more anti-HER2 treatment regimens. In June 2022, the indication was expanded to patients with HER2-positive metastatic or unresectable breast cancer who had received one anti-HER2 treatment regimen. In November 2022, the indication was further expanded to patients with metastatic or unresectable low-expression HER2 breast cancer who had received prior systemic therapy. The number of patients estimated to be eligible for the drug increased from 383 to 23,000, with an increased total cost from BRL467,970,786 (USD90,621,763) to BRL26,048,234,160 (USD5,044,197,164).

The expansion of indications for trastuzumab deruxtecan may substantially increase its financial impact and compromise the sustainability of health systems. In Brazil, the lack of monitoring of drug prices means that the only change in prices occurs due to regulated annual inflation adjustments. Regulation is needed to reduce drug prices according to new indications, changes in therapeutic options for the same condition, and obsolescence.

Aortic stenosis is an insidious disease that has a high mortality rate when it becomes symptomatic. Surgical valve replacement is the treatment of choice and has predictable risks. Transcatheter aortic valve replacement (TAVR) is a less invasive alternative to surgery, which is indicated for high-risk patients.

Complications after TAVR include paravalvular leak, cerebrovascular events, and the need for pacemaker implantation. A health technology assessment report carried out by the Health Technology Assessment Unimed-BH group in 2018, two years before it became part of the National Supplementary Health Agency, recommended the introduction of TAVR with the following criteria: indications provided by a group of specialists; forwarding of a report with detailed clinical data; results of imaging exams; and follow-up results for up to one year after the procedure. After the introduction of TAVR with the agreed criteria, it was possible to access TAVR results from the private healthcare system of Unimed-BH.

Administrative data were collected from the Unimed-BH database. All patients who received a TAVR implant from 2013 to 2017 were included by virtue of a court injunction, and after 2018 by operator concession and within agreed criteria.

From July 2013 to June 2019, 83 patients underwent TAVR implantation by Unimed BH. The median age of patients was 83.4 years (interquartile range 66.5 to 97.9), most of whom were women (56%). There was a predominance of patients in New York Heart Association classification III (50%) and IV (29%). There were 36 patients who underwent TAVR before 2018 and 47 patients within the agreed criteria. In the period prior to the agreed criteria, 28 percent needed a pacemaker, compared with 23 percent after 2018. During the follow-up period, 39 patients died: 18 (50%) before 2018 and 11 (23%) after 2018.

The agreement made with the providers, which included the obligation of having a team of specialists responsible for the indication and access to clinical data through the report, improved patient outcomes. This may be due to having a better indication for the procedure or to the greater experience of the professionals involved in its delivery.

The Corona Virus Disease 2019 (COVID-19) pandemic is the biggest public health crisis of all time. Private health care plays a major role in health globally. We conducted a study to document the engagement of a Brazilian private health care organization to influence decisions to private and public health emergencies of COVID-19.

This retrospective study evaluated the outputs of the health technology assessment (HTA) group of Unimed-BH, a private Health Maintenance Organization (HMO) with 1.5 million participants in Belo Horizonte, Minas Gerais state. The study evaluated the impacts on the overview of health local decisions in the municipality and the national supplementary health agency (ANS) during the period from March 2020 to December 2022.

During the pandemic, Unimed-BH made all its sanitary decisions based on scientific research, such as the use of masks and appropriate medications. Even though some medicines, such as regdanvimab, were authorized for emergency use by the Brazilian Health Regulatory Agency (ANVISA), Unimed-BH did not recommend their use due to uncertain evidence, and months later, ANVISA withdrew the registration.

Unimed-BH also conducted a systematic review of ivermectin for COVID-19 treatment, which showed no effect, and therefore did not recommend its use. Additionally, Unimed-BH provided weekly updates on COVID-19 data, including suspected and confirmed cases, hospitalizations, and deaths in their customer portfolio. The organization also actively supported the decisions made by ANS and municipal managers using evidence and statistics on the pandemic. The Unimed-BH HTA group produced a total of 167 reports from March 2020 to December 2022.

Belo Horizonte had the lowest in-hospital mortality rates with COVID-19 in Brazil. Unimed-BH’s HTA reports provided evidence-based assessments for decision-making, proposed partnership with policymakers, fomented information transparency, and strict follow-up on pandemic numbers, which may have contributed to the lower fatality rate in our city. These findings underscore the importance of private healthcare organizations in responding to COVID-19 emergencies, and their potential to support evidence-based decision-making and minimize the impact of the pandemic.

Most new drugs have only clinical studies focused on a single population at the time of first registration, hence their indications for use are restricted to this population. For clinical conditions when there are no other treatments available, new drugs have higher costs in Brazil. There is no review of prices when these medications broaden their therapeutic areas, and this can have a significant financial impact. This study’s objective is to assess the financial implications of pembrolizumab’s incremental indication after its initial registration.

We calculated the annual cost to treat all Brazilian patients with indications for use in the first registration and all incremental indications of pembrolizumb. Populations were estimated by epidemiological data from the pembrolizumab clinical trials called, KEYNOTE studies, and the INCA 2023 cancer estimate for the Brazilian population. Costs were calculated by CMED-ANVISA price value and considering the dosing of 200mg every 3 weeks.

In 2016, pembrolizumab was granted registration in Brazil was restricted to patients with advanced melanoma. In 2022 the indication was expanded to more than 20 new indications, with several studies in progress that potentially will lead to further inclusions. The estimate of patients eligible for indications increase of 1,796 to 99,544 patients with an increased total cost from BRL625,802,837 to BRL34,685,366,192 (USD121,185,677.4 to USD6,716,763,399.04).

The financial burden of pembrolizumab’s expanded uses after it was first approved could significantly rise, endangering the long-term viability of healthcare systems. In Brazil, where medicine costs are not regularly monitored, the annual inflation adjustment is the only factor that causes prices to change. In order to lower medicine prices in response to the addition of new indications, the expansion of therapeutic options for the same condition, or even obsolescence, regulations are required.

The fast track in drug registration by the Brazilian Health Regulatory Agency, ANVISA, began in 2017 and is intended to prioritize analysis related to drugs relevant to public health. This process is appropriate in situations where there are no therapeutic alternative available or for technologies show significant improvement in safety, efficacy, or adherence to treatment.

The Brazilian public administration has a tool for accessing information called Transparency Portal. Thus, data on the number of drugs approved by fast track between 2018 and 2021 were requested through this tool and evaluated.

The data received by the Brazilian transparency portal shows that the number of requests for fast track had an increase from one in 2018 to 32 in 2021. There is an important increase of registrations, being drugs with phase II trials and with single-arm clinical trials. With registration based on a phase II trial, these patients are in fact receiving drugs in a context similar to clinical trials, but with funding from the healthcare system. Given that phase II studies are conducted in a limited population, there has been an increase in the registration of drugs with suboptimal efficacy and safety concerns. This scenario of uncertainty leads to non-adherence to treatment and a discrepancy in real-world outcomes in comparison to the clinical trial. About 70 percent of phase II trials, show no benefit, and only 30 percent proceed to later phases. It is noteworthy that about 50 percent of the studies that move on to later phases fail to show benefits. Nowadays the number of drugs approved by the fast track has increased, many probably with phase II studies and no comparator group.

Given the uncertainties in the efficacy and safety of a drug registered via fast track, often based on phase II studies, implementing provisional registration with real-world evaluation of outcomes, and coupled with financing based on risk-sharing agreements, may be a sustainable alternative for health systems.

The Corona Virus Disease 2019 (COVID-19) pandemic has impacted the functioning of health systems, imposing the need for adaptations. Elective surgeries also needed to adapt, and research has shown higher mortality in newly infected surgical patients after or during procedures. Thus, was recommended the suspension of elective surgeries during the pandemic. Early studies evaluating the effect of COVID-19 pandemic on bariatric surgery have reported a substantial reduction in procedures performed.

This retrospective study evaluated the impact of the suspension of bariatric surgeries for a Brazilian Health Maintenance Organization: UNIMED-BH, based on the analysis of data from before and during the pandemic of COVID-19.

There were 2,641 bariatric procedures conducted in 2019 with a 14.1 percent reduction in volume to 2,314 procedures in 2020. In 2021, there were 2,813 bariatric procedures and 1,700 procedures were observed from January to August 2022. Therefore, it appears that in 2022 the demand for bariatric procedures will be similar to the year 2019, which was before the COVID-19 pandemic.

From the analysis of the data, a decrease in bariatric surgical volume was evidenced during the year 2020 when compared to 2019. Post-pandemic, monitoring is necessary to assess whether the system was able to meet the demand for bariatric surgical procedures.

The outbreak of the COVID-19 pandemic generated the need to adapt patients’ access to health services, given the rapid and exponential increase in demand at all levels of care, making social distancing one of the few weapons available in this fight. In this scenario, telehealth proved to be a fundamental tool in tracking and guiding patients with suspected or confirmed disease. This work presents the demographic profile of the people attended, the most prevalent clinical situations in care and the clinical outcomes of the remote care.

This was an observational, descriptive, cross-sectional, retrospective study carried out at Unimed Belo Horizonte, a medical work cooperative, from March 2020 to May 2021. We analyzed anonymized data on remote care from electronic medical records provided by the operator, with the remote contacts of these patients being spontaneous.

In the period evaluated, 380,663 remote calls were made, with a monthly average of 36,888 calls. Of these visits, 59.5% were carried out by women and 40.5% by men. There were, 13,211 (3.5%) consultations with patients aged 0 to 9 years, 19,933 (5.2%) 10 to 19 years, 319,882 (84%) in people aged 20 to 59 years, and 27,633 (7.3%) aged 60 years or older. There were 64,348 (17%) consultations in patients with confirmed COVID-19 and 40,997 (11%) with suspected COVID-19. There were 194,746 (51.2%) consultations due to respiratory complaints and 14% of consultations due to other causes, but whose initial care was due to signs and symptoms suggestive of COVID-19. Of people assisted remotely, 29,734 (7.8%) attended the emergency room within 3 days, while 38,685 (10.2%) sought the emergency room within 14 days. There were 2,846 (0.7%) consultations in the emergency room that resulted in the hospitalization of patients.

Telehealth proved to be resolute and an important tool for accessing health services during the pandemic.

Patients with chronic kidney disease (CKD) and COVID-19 are at high risk of adverse outcomes due to the presence of comorbidities. However, it is still unclear whether dialysis therapy is associated with a worse prognosis in patients infected with SARS-CoV-2. The objectives were to assess mortality and risk factors associated with a worse prognosis of these patients (e.g., age, sex, comorbidities, Intensive Care Admission [ICU] admission, and need for invasive mechanical ventilation [IMV]).

An observational, descriptive, retrospective study was conducted in the private healthcare maintenance organization (Unimed-BH) of Belo Horizonte and 33 surrounding cities in Brazil. We used data collected from the organization’s database. We included adult inpatients with CKD on previous dialysis therapy who tested positive for COVID-19, from February 2020 to June 2021.

During the period, 16182 patients were admitted to Unimed-BH with a diagnosis of COVID-19. Of these, 333 (2%) had dialysis CKD. Male patients were 180 (54%), age ranged from 22.85 to 95.75 years and the mean was 60.91 years. Of the 333 patients, 109 (32.7%) were admitted to the ICU, and 56 (16.8%) required IMV. Among the 14 comorbidities analysed, the mean number of comorbidities was 6, with 93 (27.9%) dyslipidaemia, 74 (22%) diabetic, 270 (81%) hypertensive, 25 (7.5%) asthmatic, 42 (12.6%) with chronic pulmonary disease (CPD) and 122 (36.6%) with congestive heart failure (CHF). There were 66 (19.8%) deaths, 29 (43.9%) were male, the mean age was 60.8 years, and 23 patients (34.8%) were elderly (>60 years). Among the patients who died, 55 (83.3%) were in the ICU and 46 (69.7%) on IMV. The mean number of comorbidities was 9.27 being 16 (24.2%) dyslipidaemia, 44 (66.6%) diabetic, 60 (90.9%) hypertensive, 5 (7%) asthmatic, 10 (15%) with CPD and 32 (48.5%) with CHF.

Dialysis patients appear more susceptible to unfavourable outcomes than the general population. Our findings are similar to those reported in the world literature which is still scarce. It is important to conduct more studies on this population.

Life expectancy is increasing worldwide. However, during the COVID-19 pandemic, people 100 years or more (centenaries) were challenged by a potentially fatal disease. We evaluated the outcome of centenaries hospitalized due to COVID-19 in a private healthcare system of Belo Horizonte/Brazil (Unimed-BH).

Administrative data were collected from the hospital database. Patients were included if they had a severe adult respiratory syndrome due to coronavirus type 2 (SARS-CoV-2) ribonucleic acid identified by quantitative real-time reverse transcriptase polymerase chain reaction (RT-qPCR) or by the International Code of Disease-10th review (ICD-10) hospitalization codes U07.1, B34.2, or B97.2.

From March 1 2020 to October 31 2021, 316.4 ± 12.9 centenaries/month were registered. Eighteen hospitalizations due to COVID-19 were identified. Median age was 101.8 years (inter-quartile range [IQR]:100.7,103.0). Most patients were female (83%). There was a median of 6.0 morbidities per patient (IQR:5.3,7.8), range 2-12 morbidities, among 71 possible morbidities. The most described morbidities were systemic arterial hypertension (94%), dementia (61%), and congestive heart failure (61%). Median length of hospitalization was 6.5 days (IQR:3.3,8.0). No patient was dialyzed. Seven (39%) patients died during hospitalization, of whom 3 (17%) were admitted to the Intensive Care Unit and 2 (11%) were oxygenated by invasive mechanical ventilation. No other patients were admitted to the Intensive Care Unit or invasively mechanically ventilated.

Although the hospitalization rate was low, the mortality rate during hospitalization was high among centenaries. Further research is required to evaluate the actual risks of centenaries to be infected by SARS-CoV-2 and the subsequent outcomes.

Severe aortic stenosis with symptoms or left ventricular dysfunction has commonly a poor prognosis and therefore, aortic valve replacement is usually performed for patients aiming at improving their functional class and survival rate.

This retrospective study evaluated a convenience sample of patients at high risk for open surgery for the correction of aortic valve dysfunction treated with TAVI from 2013 to 2018. Data from a private healthcare organization in Belo Horizonte, Brazil were used to assess all-cause mortality. Continuous variables were expressed as mean and standard deviation. Cox proportional regression model and Log-Rank test were used to adjust the survival curve.

Fifty-two patients were included in the study (mean 83 ± 5.7 years of age, range 67 to 93 years; female 55.8 percent). Patients were characterized by: left ventricular ejection fraction (n = 30; mean 52.9 percent, range 26 to 81 percent); aortic valve area (n = 36; mean 0.68 cm2, range 0.4 to 1.2 cm2); left atrium size (n = 14; range 30 to 61 ml/m2); pulmonary artery pressure (n = 20; mean 53 mmHg, range 31 to 70 mmHg). Death occurred in 19 patients during the follow-up period (mean 8.4 months, range 0 to 60 months). Nine deaths occurred within the first 30 days of follow-up (17.3 percent) and 14 (26.9 percent) in the first year. Stroke occurred in three patients (5.8 percent) in the post-implant period. A pacemaker device was required for nine patients (17.3 percent).

Transcatheter aortic valve implantation (TAVI) has become an alternative to surgical aortic valve replacement for patients at high risk for surgery. Real-world studies might result in a better understanding of the local team expertise on TAVI utilization.

Open repair was considered for several years the gold standard therapy for the treatment of peripheral artery aneurysms (PAAs). However, with advancements in endovascular technology increasing attention has been directed toward repairing PAAs using an endovascular stent graft.

This retrospective study evaluated a cohort of patients after the correction of PAAs with Viabahn. Patients treated from January 2011 to January 2018 were assessed for all-cause mortality, amputation and the need for re-intervention. Data were extracted from an administrative database from a healthcare organization in Belo Horizonte, Brazil.

Fifty-two patients were included in the study (median age 69.1 years, range 15 to 90 years; male 63.5 percent), three of whom also received Viabahn for contralateral PAAs. In total, 84 devices were used (average 1.5 per PAA); distribution: popliteal and tibial arteries (n = 30; 57 percent), femoral and iliac arteries (n = 19; 37 percent), axillary artery (n = 1; 2 percent), splenic artery (n = 1; 2 percent), abdominal aorta (n = 1; 2 percent). After a mean follow up time of 1.98 ± 1.68 years, we observed death (n = 3; 5.8 percent), amputation (n = 3; 5.8 percent) and the need for re-intervention (n = 17; 32.6 percent) in 23 patients (44.2 percent). The combined overall survival for the first, second and third year of follow up was 70.2 percent (Confidence Interval [95% CI]: 58.9 - 83.6); 63 percent (95% CI: 51.0 - 78.0) and 57.3 percent (95% CI 44.6 - 73.6).

There are still several unanswered questions regarding the best approach for patients with PAAs. In the absence of well-designed clinical studies, the assessment of databanks on real-world patients may contribute to improve our understanding of treatment alternatives and provide guidance to improve current clinical results.

Many patients presenting with arrhythmias are treated with antiarrhythmic drug therapy. However, for some patients, usually survivors of previous serious ventricular arrhythmias, treatment implies the use of implantable cardioverter defibrillators (ICDs) and/or Cardiac Resynchronization Therapy (CRT) devices.

This retrospective study evaluated a cohort of patients with arrhythmia requiring the use of ICDs, CRT or ICDs + CRT from January 2004 to March 2018. Data from a private healthcare organization in Belo Horizonte, Brazil were used to assess all-cause mortality and the need for replacement of the device. Continuous variables were expressed as mean and standard deviation. Cox proportional regression model and Log-Rank test were used to adjust the survival curve.

Five hundred and ninety-three patients were included in the study (median age 67.6 years, range 23 to 89 years; male 62 percent). According to the type of device used to treat these patients, the distribution was 338 (57.0 percent), 169 (28.5 percent), 86 (14.5 percent), for ICDs, ICDs + CRT, CRT, respectively. After a mean follow-up time of 3.12 years (range 0 to 13.6 years), 283 devices were replaced (ICDs n = 140; ICDs + CRT n = 90; CRT n = 53) and 284 deaths occurred (median survival of 6.9 years). The median survival was 7.3, 5.8, 4.8, 5.5 years for ICDs single-chamber, ICDs dual-chamber, ICDs + CRT, CRT, respectively.

Randomized trials are often criticized for their enrollment of highly selected patients. Studies on real-word data can provide reliable information regarding the use of ICDs and/or CRT devices in the treatment of patients with serious ventricular arrhythmias.

Bariatric surgery has become one of the fastest growing operative procedures due to its sustained results and the increasing prevalence of obesity worldwide. Despite this fact, bariatric surgery carries the usual risks and threats of surgical interventions and therefore its benefits might be undermined by its mid and long-term complications.

This retrospective study included obese patients requiring bariatric surgery from January 2004 to December 2017 provided by a private healthcare organization in Belo Horizonte, Brazil. Data regarding healthcare utilization were extracted from an administrative database (software Oracle Business Intelligence). Continuous variables were expressed as mean and standard deviation. Log-Rank test was used to adjust the survival curve (software STATA 13.1, Stata Corp, USA). This historical cohort resulted in no interventions, neither during the instituted treatment nor after the observed outcome. Privacy of subjects and the confidentiality of their personal information were handled in accordance with the ethical principles of the Declaration of Helsinki.

In total, 16,786 patients were included in the study (mean age 37.2 ± 10.2 years; female 79.2 percent; mean body mass index 42.4 ± 5.5 kg/m2). Patients were followed for up to seven years before and after surgery (total of 78,113 patients/year). For this group, the hospitalization rate was 0.099 / patients-year before versus 0.151 / patients-year after the bariatric surgery (p < 0.001). There were 224 deaths (1.33 percent) identified during the follow-up period, 0.4 percent in the first 30 postoperative days. The average costs for hospitalization were USD 3,339.36 and USD 4,305.04 for open and laparoscopic surgery, respectively.

Bariatric surgery has been an increasingly popular choice in the management of obesity. In our sample, it did not reduce the overall mid-term healthcare utilization rate.

Severe aortic stenosis with symptoms or left ventricular dysfunction has commonly a poor prognosis. Aortic valve replacement is usually performed for these patients aiming at improving their functional class and survival rate. Transcatheter aortic valve implantation (TAVI) is often presented as an option in patients with high surgical risk for conventional surgical valve replacement.(1) Nonetheless, in this group of patients, the literature has yielded conflicting evidence suggesting that benefits of TAVI for patients of high or intermediate surgical risk is not consistent.(2,3)

This retrospective study aimed to evaluate the mortality rate from a cohort of patients after the correction of aortic valve dysfunction with TAVI. It consisted of a convenience sample of patients at high risk for open surgery for the correction of aortic valve dysfunction treated with TAVI from 2013 to 2016. All included patients were being provided healthcare assistance by a private nonprofit health maintenance organization (HMO) operating in Belo Horizonte, Brazil. Since TAVI is not currently covered by the Brazilian supplementary healthcare system, reimbursements were enforced by lawsuits. Data was extracted from an administrative database, using the software Oracle Business Intelligence®. Continuous variables were expressed as mean and standard deviation. The Kaplan-Meier method was used to adjust the 1-year survival curve using the software STATA 13.1 (Stata Corp, College Station, TX, USA). This historical cohort resulted in no interventions, neither during the course of the instituted treatment nor after the observed outcome. Privacy of subjects and the confidentiality of their personal information were handled in accordance to the ethical principles of the Declaration of Helsinki.

Overall, seventeen patients with a mean age of 80.5 years (68-91) underwent TAVI; 59 percent were women. Peri-operative mortality rate was 23.5 percent (n = 4) and accumulated overall one-year mortality was 35.3 percent (n = 6). Mean length of hospital stay was 26.9 ± 16.6 days. Prolonged hospital stay (≥ 7 days) occurred in 14/17 cases (82.3 percent), with a maximum of 51 days.

In similarity to our findings, other authors described a high early and late mortality rate in patients undergoing TAVI. The strategy to use TAVI as an alternative in patients at high risk for open surgery is still under debate and should be carefully discussed taking into consideration the local team expertise as well as local healthcare available recourses.
