Natural history of familial cerebral cavernous malformation syndrome in children: a multicenter cohort study.

PURPOSE: There is limited data concerning neuroimaging findings and longitudinal evaluation of familial cerebral cavernous malformations (FCCM) in children. Our aim was to study the natural history of pediatric FCCM, with an emphasis on symptomatic hemorrhagic events and associated clinical and imaging risk factors. METHODS: We retrospectively reviewed all children diagnosed with FCCM in four tertiary pediatric hospitals between January 2010 and March 2022. Subjects with first available brain MRI and [Formula: see text] 3 months of clinical follow-up were included. Neuroimaging studies were reviewed, and clinical data collected. Annual symptomatic hemorrhage risk rates and cumulative risks were calculated using survival analysis and predictors of symptomatic hemorrhagic identified using regression analysis. RESULTS: Forty-one children (53.7% males) were included, of whom 15 (36.3%) presenting with symptomatic hemorrhage. Seven symptomatic hemorrhages occurred during 140.5 person-years of follow-up, yielding a 5-year annual hemorrhage rate of 5.0% per person-year. The 1-, 2-, and 5-year cumulative risks of symptomatic hemorrhage were 7.3%, 14.6%, and 17.1%, respectively. The latter was higher in children with prior symptomatic hemorrhage (33.3%), CCM2 genotype (33.3%), and positive family history (20.7%). Number of brainstem (adjusted hazard ratio [HR] = 1.37, P = 0.005) and posterior fossa (adjusted HR = 1.64, P = 0.004) CCM at first brain MRI were significant independent predictors of prospective symptomatic hemorrhage. CONCLUSION: The 5-year annual and cumulative symptomatic hemorrhagic risk in our pediatric FCCM cohort equals the overall risk described in children and adults with all types of CCM. Imaging features at first brain MRI may help to predict potential symptomatic hemorrhage at 5-year follow-up.

Comparative analysis of completeness of death registration, adult mortality and life expectancy at birth in Brazil at the subnational level.

BACKGROUND: Estimates of completeness of death registration are crucial to produce estimates of life tables and population projections and to estimate the burden of disease. They are an important step in assessing the quality of data. In the case of subnational data analysis in Brazil, it is important to consider spatial and temporal variation in the quality of mortality data. There are two main sources of data quality evaluation in Brazil, but there are few comparative studies and how they evolve over time. The aim of the paper is to compare and discuss alternative estimates of completeness of death registration, adult mortality (45q15) and life expectancy estimates produced by the National Statistics Office (IBGE), Institute for Health Metrics and Evaluation (IHME), and estimates presented in Queiroz et al. (2017) and Schmertmann and Gonzaga (2018), for 1980 and 2010. METHODS: We provide a descriptive and comparative analysis of aforementioned estimates from four (4) sources of estimates at subnational level (26 states and one Federal District) in Brazil from two different points in time. RESULTS: We found significant differences in estimates that affect both levels and trends of completeness of adult mortality in Brazil and states. IHME and Queiroz et al. (2017) estimates converge by 2010, but there are large differences when compared to estimates from the National Statistics Office (IBGE). Larger differences are observed for less developed states. We have showed that the quality of mortality data in Brazil has improved steadily overtime, but with large regional variations. However, we have observed that IBGE estimates show the lowest levels of completeness for the Northern of the country compared to other estimates. Choice of methods and approaches might lead to very unexpected results. CONCLUSION: We produced a detailed comparative analysis of estimates of completeness of death registration from different sources and discuss the main results and possible explanations for these differences. We have also showed that new improved methods are still needed to study adult mortality in less developed countries and at a subnational level. More comparative studies are important in order to improve quality of estimates in Brazil.

Implementation of Telehealth Resources in Primary Care in Brazil and Its Association with Quality of Care.

Background:Although several reviews on the relation between telemedicine and health care outcomes have pointed out some evidence, they have also underscored the need for further investigation.Introduction:Brazil has a national telehealth program implemented in 2007, involving teleconsulting and distance education actions in primary care.Objective:This study aims to describe the implementation of telehealth in primary care in Brazil and to identify if there is an association between telehealth and quality of care.Methods:A cross-sectional study analyzing data from interviews with 29,778 primary care team professionals in Brazil in 2014, which represents 92.5% of existing health care teams, on aspects of information technology, telehealth, and care was carried out. A multiple binary regression analysis was performed to study the associations between the extent of health care actions and using telehealth.Results:Of the 24,055 primary care units in Brazil where teams worked, only 50.1% (n: 12,055) had internet access, and 32.71% of teams claimed to be involved in telehealth actions in 2014. Between 2012 and 2014 there was an expansion in the use of telehealth resources in all regions of Brazil. The highest magnitude was observed for the association between employment of telehealth and improvement in child care (odds ratio [OR] = 2.09), followed by diabetes mellitus care (OR = 1.91), hypertension (OR = 1.89), and finally, women's health (OR = 1.86).

Cause-specific mortality for 249 causes in Brazil and states during 1990-2015: a systematic analysis for the global burden of disease study 2015.

BACKGROUND: Reliable data on cause of death (COD) are fundamental for planning and resource allocation priorities. We used GBD 2015 estimates to examine levels and trends for the leading causes of death in Brazil from 1990 to 2015. METHODS: We describe the main analytical approaches focused on both overall and specific causes of death for Brazil and Brazilian states. RESULTS: There was an overall improvement in life expectancy at birth from 1990 to 2015, but with important heterogeneity among states. Reduced mortality due to diarrhea, lower respiratory infections, and other infectious diseases contributed the most for increasing life expectancy in most states from the North and Northeast regions. Reduced mortality due to cardiovascular diseases was the highest contributor in the South, Southeast, and Center West regions. However, among men, intentional injuries reduced life expectancy in 17 out of 27 states. Although age-standardized rates due to ischemic heart disease (IHD) and cerebrovascular disease declined over time, these remained the leading CODs in the country and states. In contrast, leading causes of premature mortality changed substantially - e.g., diarrheal diseases moved from 1st to 13th and then the 36th position in 1990, 2005, and 2015, respectively, while violence moved from 7th to 1st and to 2nd. Overall, the total age-standardized years of life lost (YLL) rate was reduced from 1990 to 2015, bringing the burden of premature deaths closer to expected rates given the country's Socio-demographic Index (SDI). In 1990, IHD, stroke, diarrhea, neonatal preterm birth complications, road injury, and violence had ratios higher than the expected, while in 2015 only violence was higher, overall and in all states, according to the SDI. CONCLUSIONS: A widespread reduction of mortality levels occurred in Brazil from 1990 to 2015, particularly among children under 5 years old. Major shifts in mortality rates took place among communicable, maternal, neonatal, and nutritional disorders. The mortality profile has shifted to older ages with increases in non-communicable diseases as well as premature deaths due to violence. Policymakers should address health interventions accordingly.

Clinical trials in palliative care: a systematic review of their methodological characteristics and of the quality of their reporting.

BACKGROUND: Over the past decades there has been a significant increase in the number of published clinical trials in palliative care. However, empirical evidence suggests that there are methodological problems in the design and conduct of studies, which raises questions about the validity and generalisability of the results and of the strength of the available evidence. We sought to evaluate the methodological characteristics and assess the quality of reporting of clinical trials in palliative care. METHODS: We performed a systematic review of published clinical trials assessing therapeutic interventions in palliative care. Trials were identified using MEDLINE (from its inception to February 2015). We assessed methodological characteristics and describe the quality of reporting using the Cochrane Risk of Bias tool. RESULTS: We retrieved 107 studies. The most common medical field studied was oncology, and 43.9% of trials evaluated pharmacological interventions. Symptom control and physical dimensions (e.g. intervention on pain, breathlessness, nausea) were the palliative care-specific issues most studied. We found under-reporting of key information in particular on random sequence generation, allocation concealment, and blinding. CONCLUSIONS: While the number of clinical trials in palliative care has increased over time, methodological quality remains suboptimal. This compromises the quality of studies. Therefore, a greater effort is needed to enable the appropriate performance of future studies and increase the robustness of evidence-based medicine in this important field.

A systematic review of the characteristics and validity of monitoring technologies to assess Parkinson's disease.

BACKGROUND: There is growing interest in having objective assessment of health-related outcomes using technology-based devices that provide unbiased measurements which can be used in clinical practice and scientific research. Many studies have investigated the clinical manifestations of Parkinson's disease using such devices. However, clinimetric properties and clinical validation vary among the different devices. METHODS: Given such heterogeneity, we sought to perform a systematic review in order to (i) list, (ii) compare and (iii) classify technological-based devices used to measure motor function in individuals with Parkinson's disease into three groups, namely wearable, non-wearable and hybrid devices. A systematic literature search of the PubMed database resulted in the inclusion of 168 studies. These studies were grouped based on the type of device used. For each device we reviewed availability, use, reliability, validity, and sensitivity to change. The devices were then classified as (i) 'recommended', (ii) 'suggested' or (iii) 'listed' based on the following criteria: (1) used in the assessment of Parkinson's disease (yes/no), (2) used in published studies by people other than the developers (yes/no), and (3) successful clinimetric testing (yes/no). RESULTS: Seventy-three devices were identified, 22 were wearable, 38 were non-wearable, and 13 were hybrid devices. In accordance with our classification method, 9 devices were 'recommended', 34 devices were 'suggested', and 30 devices were classified as 'listed'. Within the wearable devices group, the Mobility Lab sensors from Ambulatory Parkinson's Disease Monitoring (APDM), Physilog®, StepWatch 3, TriTrac RT3 Triaxial accelerometer, McRoberts DynaPort, and Axivity (AX3) were classified as 'recommended'. Within the non-wearable devices group, the Nintendo Wii Balance Board and GAITRite® gait analysis system were classified as 'recommended'. Within the hybrid devices group only the Kinesia® system was classified as 'recommended'.

[Health care, quality certification and institutional support: a focus on primary health care in Brazil]. / Asistencia sanitaria, certificación de calidad y apoyo institucional: la atención primaria en Brasil.

OBJECTIVE: To provide an overview of the distribution of institutional support in primary care in Brazil and to identify associations between the activities of institutional support and the outcome of the certification of the National Programme for Improving Access and Quality in Primary Health Care (PMAQ). MATERIALS AND METHODS: A cross-sectional study was conducted through interviews with 16 960 professionals in Brazil in 2012.To examine the relationship between the received support and the quality of health care it was made a multiple binary logistic regression. RESULTS: A positive relationship between high-level support and certification in the sub-dimensions analyzed was observed: women and child care, diabetes mellitus/ hypertension and mental health.The support activities which contributed most were: self-assessment, shared assessment, targeted workshops and training. CONCLUSION: Institutional support activities have helped to improve the quality and access of the population to healthcare in the country.

Substantia nigra neuromelanin-MR imaging differentiates essential tremor from Parkinson's disease.

BACKGROUND: Essential tremor (ET) is a very common movement disorder that has no diagnostic markers. Differentiation with Parkinson's disease (PD) can be clinically challenging in some cases, with a high rate of misdiagnosis. Magnetic resonance imaging (MRI) studies have been able to identify neuromelanin changes in the substantia nigra (SN) of PD patients, but they have thus far not been investigated in ET. In this study, we aimed to characterize neuromelanin-MR signal changes in ET and evaluate its diagnostic accuracy in the differential diagnosis with PD. METHODS: The inclusion criteria were patients with ET and untreated "de novo" PD patients; in addition, age-matched controls were enrolled. These were studied with a high-resolution T1-weighted MRI sequence at 3.0 Tesla to visualize neuromelanin. The primary outcomes were the area and width of the SN region with high signal. RESULTS: A total of 15 ET patients and 12 "de novo" PD patients were evaluated. The area and width of the T1 high signal in the SN region were markedly decreased in the PD group compared with the ET and age-matched controls, and a greater decrease was seen in the ventrolateral segment. The neuromelanin measures in the ET group, although slightly lower, were not significantly different from the healthy control group. We obtained a sensitivity of 66.7% and a specificity of 93.3% in discriminating ET from early-stage PD. CONCLUSIONS: Neuromelanin-sensitive MRI techniques can discriminate ET from early-stage tremor-dominant PD and can be a useful clinical tool in the evaluation of tremor disorders. © 2015 International Parkinson and Movement Disorder Society.

Quantitative home-based assessment of Parkinson's symptoms: the SENSE-PARK feasibility and usability study.

BACKGROUND: Currently, assessment of symptoms associated with Parkinson's disease is mainly performed in the clinic. However, these assessments have limitations because they provide only a snapshot of the condition. METHODS: The feasibility and usability of an objective, continuous and relatively unobtrusive system (SENSE-PARK System), which consists of wearable sensors (three worn during the day and one worn at night), a smartphone-based App, a balance board and computer software, was tested 24/7 over 12 weeks in a study including 22 PD patients. During the first four weeks of the study, patients did not get feedback about their performance, during the last eight weeks they did. The study included seven clinical visits with standardized interviews, and regular phone contact. The primary outcome was the number of drop-outs during the study. As secondary outcomes, the Post-Study System Usability Questionnaire (PSSUQ), score and information obtained from the standardized interviews were used to evaluate the usability of the system. RESULTS: All patients completed the study. The participants rated the usability of the SENSE-PARK System with a mean score of 2.67 (±0.49) on the PSSUQ. The interviews revealed that most participants liked using the system and appreciated that it signaled changes in their health condition. CONCLUSIONS: This 12 week controlled study demonstrates that the acceptance level of PD patients using the SENSE-PARK System as a home-based 24/7 assessment is very good. Particular emphasis should be given to a user-friendly design. Motivation to wear such a system can be increased by providing direct feedback about the individual health condition.

Risk of insomnia with non-vitamin K oral anticoagulants: systematic review and meta-analysis.

PURPOSE: Insomnia is an important adverse event of mechanical thromboprophylaxis. This sleep disorder has been reported as one of the commonest adverse events of the new oral anti-Xa anticoagulant darexaban, with similar rates to mechanical thromboprophylaxis in a randomized controlled trial (RCT). However, the perceived effect could have been biased because it was an open-label RCT. Therefore, we aimed to review the incidence of insomnia with non-vitamin K antagonist oral anticoagulants (NOACs). METHODS: We performed a systematic review and meta-analysis of Phase III RCTs. Electronic databases MEDLINE and CENTRAL (inception to September 2013) were searched as well as review articles and references of included studies. We included phase III RCTs which compared NOACs with any other control group. Data were analyzed and pooled to estimate risk ratio (RR) with 95% confidence intervals (95%CI) for insomnia using inverse variance method. Statistical heterogeneity was evaluated with I(2) test. RESULTS: We included seven studies (two apixaban RCTs, two dabigatran RCTs, one darexaban RCTs, and two rivaroxaban RCTs), enrolling a total of 23,023 patients. Overall, NOACs were not associated to an increased risk of insomnia: RR 0.94 (95%CI 0.83-1.08; I(2) = 0%). In blinded studies (six studies), NOACs also did not show increased risk of insomnia (RR 0.94, 95%CI 0.83-1.08; I(2) = 0%). Results were similar irrespective of the comparators. CONCLUSIONS: NOACs (apixaban, dabigatran, darexaban, rivaroxaban) did not show increased risk of insomnia. Results according to study design (blinded vs. open-label trials) overlap the main analysis.

Trends in dietary intake in Switzerland, 1999 to 2009.

OBJECTIVE: To assess nutrition trends of the Geneva population for the period 1999-2009. DESIGN: Bus Santé Geneva study, which conducts annual health surveys in random samples of the Geneva population. Dietary intake was assessed using a validated FFQ and trends were assessed by linear regression. SETTING: Population-based survey. SUBJECTS: Data from 9283 participants (50% women, mean age 51·5 (sd 10·8) years) were analysed. RESULTS: In both genders total energy intake decreased from 1999 to 2009, by 2·9% in men and by 6·3% in women (both trends P < 0·005). Vegetable protein and total carbohydrate intakes, expressed as a percentage of total energy intake, increased in women. MUFA intake increased while SFA, PUFA and alcohol intakes decreased in both genders. Intakes of Ca, Fe and carotene decreased in both genders. No changes in fibre, vitamin D and vitamin A intakes were found. Similar findings were obtained after excluding participants with extreme dietary intakes, except that the decreases in SFA, vegetable protein and carbohydrate were no longer significant in women. CONCLUSIONS: Between 1999 and 2009, a small decrease in total energy intake was noted in the Geneva population. Although the decrease in alcohol and SFA intakes is of interest, the decrease in Ca and Fe intakes may have adverse health effects in the future.

Curricular transformations in medical school: an exploration of the promotion of change in Brazil.

CONTEXT: Curricular transformation is complex and involves many interrelated and influential factors. The idiosyncratic nature of the time-frame in which curricular change takes place makes it difficult to study these factors systematically. In 2002, the Brazilian government established the Programme of Incentives for Curricular Changes in Medical Schools (PROMED). Nineteen schools participated in the programme and were given resources to finance curricular reforms in an effort to align their course structures with the tenets of the government proposal. This study analyses reforms in coursework among the schools in this cohort in an effort to better understand the impact of such incentive programmes and factors that might influence the degree of impact across institutions. METHODS: We compared data on the schools before and after their participation in PROMED. To facilitate comparison, we used a scheme of axes and vectors to classify the schools according to the profundity of the curricular changes, ranging from the most conservative to the most innovative. The data used for the classification were obtained through document analysis, interviews and focus group discussions. RESULTS: Different trends were observed for each axis. Important changes were noticed in the pedagogic approach axis, particularly in terms of pedagogic changes, which called for the adoption of active teaching and learning methods. The practice scenarios axis also underwent considerable changes, specifically in terms of primary health care. The vector related to production of knowledge pertaining to health system needs showed fewer changes; none of the schools reached stage 3 (effective fulfilment of an educational innovation). CONCLUSIONS: The PROMED initiative provided considerable support for implementing and consolidating curricular reforms that placed greater emphasis on the needs of society and the health care system. The different trends observed revealed the complexity behind curricular transformation and highlighted the need for the collective construction of curricula with the participation of all groups involved.

Racial disparities and avoidable infant mortality in a city of Southeastern Brazil, 2001-09.

This study aims to evaluate the quality of information about race/colour (black or white) in health information systems and to analyse the causes of infant mortality in the Brazilian List of Avoidable Causes of Death by race/colour in Belo Horizonte in 2001-09. Infant deaths and live births were obtained from the Brazilian Information Systems on Mortality and Live Births. After redistribution of missing data, infant mortality rate (IMR) was estimated for blacks and whites and was stratified by birth weight. Deaths were classified in avoidable, ill-defined or non-avoidable causes. Regardless of birth weight, avoidable mortality rate was higher among black infants. Low quality of care during pregnancy and delivery was more likely among black women. Inadequate care of low-birth-weight black newborns also led to their increased risk of death. To reduce infant mortality and inequality, we must identify black infants as the most vulnerable group and increase the efficiency of health services in preventing avoidable deaths.

Contributory Factors to Caregiver Burden in Parkinson's Disease.

Background: Although there is growing recognition of the relevancy of informal caregivers there is scarce information on the contributory factors of caregiver burden in Parkinson's Disease (PD). Objective: To identify the main associated factors to caregivers' burden in people caring for a person with PD. Methods: We analyzed the data set from a multinational online survey the Parkinson's real-world impact assesSMent (PRISM) focusing on medication use, comorbidities, health-related quality of life, relationship changes and the use of healthcare and supportive care resources by people with PD and their carers. Structured questionnaires including the Parkinson's disease quality of life questionnaire (PDQ-39), non-motor symptoms questionnaire (NMSQuest) and the Questionnaire for impulsive-compulsive disorder in Parkinson's disease (QUIP) were applied. Caregiver burden was assessed by the Zarit Burden Interview (ZBI). Results: In a cohort of 245 dyads (patient and respective caregiver), caregivers reported a mild to moderate burden. Carers' perception of PD impact in partnership, financial burden, hours of care, patient's age, hypersexuality and health-related quality of life (HRQoL) were found to be significant contributory factors to caregiver burden. Taken together these variables explained 66.8% of the variance in the Interpretation of the ZBI total score. Conclusions: Caring for a person with PD entails substantial burden, particularly when the caregiver perceives greater changes in partnership dynamics, dedicates more time to caregiving tasks, has financial burden, and when the patient is older, reports worst HRQoL and has sexual compulsive urges.

The translation into Portuguese of the 11th International Statistical Classification of Diseases and Related Health Problems (ICD-11). / Tradução para a língua portuguesa da 11a Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde (CID-11).

The 11th International Statistical Classification of Diseases and Related Health Problems (ICD-11) represents an advance in the focus on knowledge and new disease approaches. The ICD is used for different practical purposes, enabling assessment of progress in the global health agenda, resource allocation, patient safety, health care qualification, and health insurance reimbursement. It is entirely digital, with technological resources that allow periodic updating. In early 2022, ICD-11 entered into official force, having been made available in several official ICD languages such as Arabic, Chinese, Spanish, French, and English. The translation process into Brazilian Portuguese, coordinated by the Federal University of Minas Gerais (UFMG), with support from the Brazilian Ministry of Health (MS) and PAHO/WHO, is presented here. The work was carried out in three stages between August 2021 and December 2022 by translators with different backgrounds: medical specialists (49), physiotherapists (1), pharmacologists (1), and dentists (1). This methodological article aims to broaden the discussion of perspectives on implementing the ICD-11 in Brazil and build an opportunity for its adaptation and use by other Portuguese-speaking countries.

Comparison of crude and adjusted mortality rates from leading causes of death in northeastern Brazil.

OBJECTIVE: To present how the adjustment of incompleteness and misclassification of causes of death in the vital registration (VR) system can contribute to more accurate estimates of the risk of mortality from leading causes of death in northeastern Brazil. METHODS: After estimating the total numbers of deaths by age and sex in Brazil's Northeast region in 2002-2004 by correcting for undercount in the VR data, adjustment algorithms were applied to the reported cause-of-death structure. Average annual age-standardized mortality rates were computed by cause, with and without the corrections, and compared to death rates for Brazil's South region after adjustments for potential misdiagnosis. RESULTS: Death rates from ischemic heart disease, lower respiratory infections, chronic obstructive pulmonary disease, and perinatal conditions were more than 100% higher for both sexes than what was suggested by the routine VR data. Corrected cause-specific mortality rates were higher in the Northeast region versus the South region for the majority of causes of death, including several noncommunicable conditions. CONCLUSIONS: Failure to adjust VR data for undercount of cases reported and misdiagnoses will cause underestimation of mortality risks for the populations of the Northeast region, which are more vulnerable than those in other regions of the country. In order to more reliably understand the pattern of disease, all cause-specific mortality rates in poor populations should be adjusted.

Excess Mortality due to natural causes among whites and blacks during the COVID-19 pandemic in Brazil.

INTRODUCTION: Excess Mortality by all causes considers deaths directly related to COVID-19 and those attributed to conditions caused by the pandemic. When stratified by social dimensions, such as race/color, it allows for the evaluation of more vulnerable populations. The study estimated the excess mortality by natural causes, separating the white and black populations in 2020. METHODS: Public civil registration data on deaths observed in 2020, corrected for under registration, were used. The expected number of deaths was estimated based on the mortality rates observed in 2019, applied to the estimated population in 2020. The difference between the values expected and observed and the proportion of excess was considered the excess mortality. RESULTS: The present study found an excess of 270,321 deaths (22.2% above the expected) in 2020. Every state of Brazil reported deaths above the corresponding expected figure. The excess was higher for men (25.2%) than for women (19.0%). Blacks showed an excess of 27.8%, as compared to whites at 17.6%. In both sexes and all age groups, excess was higher in the black population, especially in the South, Southeast, and Midwest regions. São Paulo, the largest in population number, had twice as much excess death in the black population (25.1%) than in the white population (11.5%). CONCLUSIONS: The present study showed racial disparities in excess mortality during the COVID-19 pandemic in Brazil. The higher excess found for the black suggests an intrinsic relationship with the socioeconomic situation, further exposing the Brazilian reality, in which social and structural inequality is evident.

[Assessment of the coordination of primary healthcare: comparison of PMAQ-AB (Brazil) and international references]. / Avaliação da coordenação do cuidado na atenção primária à saúde: comparando o PMAQ-AB (Brasil) e referências internacionais.

This study aimed to compare the results obtained with the coordination of care through the Brazilian National Program for Improvement of Access and Quality of Basic Care (PMAQ-AB), with the parameters adopted by the Care Coordination Measures Atlas and the European Observatory on Health Systems and Policies. A cross-sectional study was performed using the dataset from the third cycle of the PMAQ-AB. Three typologies of coordination of care were created: PMAQ-AB, Atlas, and Observatory. Chi-square test was applied to compare proportions and Kruskal-Wallis and Nemenyi tests to verify and identify potential differences between the typologies. Significance was set at 5%. In all, 35,350 teams were assessed that performed some activity in care coordination. A significant difference was observed (p < 0.001) between levels of coordination, with a higher percentage between the high and medium levels in the three instruments, PMAQ-AB (56.07% and 38.35%), Atlas (52.63% and 40.66%), and Observatory (44.82% and 43.98%). In the comparison of the indicators, there was a significant difference (p < 0.001) between the typologies. For Brazil, in the PMAQ-AB typology, all the strata displayed a higher percentage between the high and medium levels; in the Atlas, stratum 1 stood out in the medium level (43.81%); the high level predominated in the Observatory. In the comparison of the indicators by strata, at least one stratum differed from the others (p < 0.001). Number 6 differed from the others (p < 0.001), and number 1 differed from all of them (p < 0.001) except number 2 (p > 0.05). The levels of coordination of care differed according to the instruments used. High and medium levels were identified, showing the need for additional studies.

Para Brasil, en la tipología PMAQ-AB todos los estratos expusieron un mayor porcentaje entre el nivel alto y medio; en el Atlas, el estrato 1 se destacó en el nivel medio (43,81%) y, en el Observatorio, predominó el nivel alto. En la comparación de los indicadores por estratos, por lo menos un estrato difirió de los demás (p < 0,001). El 6 se distinguió de los demás (p < 0,001), y el 1 difirió de todos (p < 0,001), excepto del 2 (p > 0,05). Los niveles de coordinación del cuidado se diferenciaron entre los instrumentos utilizados. Se identificaron niveles altos y medios, demostrando la necesidad de estudios adicionales.

Measuring misclassification of Covid-19 as garbage codes: Results of investigating 1,365 deaths and implications for vital statistics in Brazil.

The purpose of this article is to quantify the amount of misclassification of the Coronavirus Disease-2019 (COVID-19) mortality occurring in hospitals and other health facilities in selected cities in Brazil, discuss potential factors contributing to this misclassification, and consider the implications for vital statistics. Hospital deaths assigned to causes classified as garbage code (GC) COVID-related cases (severe acute respiratory syndrome, pneumonia unspecified, sepsis, respiratory failure and ill-defined causes) were selected in three Brazilian state capitals. Data from medical charts and forensic reports were extracted from standard forms and analyzed by study physicians who re-assigned the underlying cause based on standardized criteria. Descriptive statistical analysis was performed and the potential impact in vital statistics in the country was also evaluated. Among 1,365 investigated deaths due to GC-COVID-related causes, COVID-19 was detected in 17.3% in the age group 0-59 years and 25.5% deaths in 60 years and over. These GCs rose substantially in 2020 in the country and were responsible for 211,611 registered deaths. Applying observed proportions by age, location and specific GC-COVID-related cause to national data, there would be an increase of 37,163 cases in the total of COVID-19 deaths, higher in the elderly. In conclusion, important undercount of deaths from COVID-19 among GC-COVID-related causes was detected in three selected capitals of Brazil. After extrapolating the study results for national GC-COVID-related deaths we infer that the burden of COVID-19 disease in Brazil in official vital statistics was probably under estimated by at least 18% in the country in 2020.
