Epilepsy trends in Kazakhstan: A retrospective longitudinal study using data from unified national electronic health system 2014–2020

ObjectiveThis study is designed to estimate the epidemiology of epilepsy in Kazakhstan, using a large-scale administrative health database during 2014–2020. MethodsUsing the Unified National Electronic Health System of Kazakhstan over a seven-year span, we explored incidence and prevalence rates, disability-adjusted life years (DALY), and all-cause mortality. Regression models using Cox proportional hazards were used to analyze the sociodemographic, mental, behavioral, and neurological factors affecting survival. Overall analyses were performed using STATA (V.16). ResultsThe total cohort comprised of 82,907 patients, with a significant increase in the incidence of epilepsy from 26.15 in 2014 to 88.80 in 2020 per 100,000 people. Similar trends were observed in the prevalence rates, which tripled from 26.06 in 2014 to 73.10 in 2020. While mortality rates fluctuated, the elderly and children had the greatest rates of 9.97 and 2.98 per 1000 person-years respectively. DALYs revealed a substantial disease burden, with 153,532 DALYs (824.5 per 100,000) being lost during the study period. A few comorbidities, such as cerebral palsy (adjusted hazard ratio (aHR) 2.23) and central nervous system atrophy (aHR, 27.79), markedly elevated all-cause mortality. Furthermore, extrapyramidal and movement disorders (aHR 2.16, p = 0.06) and demyelinating diseases of the central nervous system (aHR 6.36, p = 0.06) showed a trend toward increased mortality risk. ConclusionTo the best of our knowledge, this is the first study from Central Asia exploring a large epilepsy cohort. The findings highlight the need for targeted interventions to address the growing burden of epilepsy, particularly among children, male sex, and those with neurological comorbities.

The progress test as a structuring initiative for programmatic assessment

BackgroundThe Progress Test is an individual assessment applied to all students at the same time and on a regular basis. The test was structured in the medical undergraduate education of a conglomerate of schools to structure a programmatic assessment integrated into teaching. This paper presents the results of four serial applications of the progress test and the feedback method to students.MethodsThis assessment comprises 120 items offered online by means of a personal password. Items are authored by faculty, peer-reviewed, and approved by a committee of experts. The items are classified by five major areas, by topics used by the National Board of Medical Examiners and by medical specialties related to a national Unified Health System. The correction uses the Item Response Theory with analysis by the “Rasch” model that considers the difficulty of the item.ResultsStudent participation increased along the four editions of the tests, considering the number of enrollments. The median performances increased in the comparisons among the sequential years in all tests, except for test1 – the first test offered to schools. Between subsequent years of education, 2nd-1st; 4th-3rd and 5th-4th there was an increase in median scores from progress tests 2 through 4. The final year of undergraduate showed a limited increase compared to the 5th year. There is a consistent increase in the median, although with fluctuations between the observed intervals.ConclusionThe progress test promoted the establishment of regular feedback among students, teachers and coordinators and paved the road to engagement much needed to construct an institutional programmatic assessment.

Serosurvey of Toxoplasma gondii and Toxocara spp. co-infection in pregnant women in low-income areas of Brazil.

Despite human toxoplasmosis and toxocariasis having been listed among the top six most neglected parasitic zoonoses worldwide, presenting similar associated risk factors and transmission routes, few studies have been conducted in pregnant women and the consequences of concurrent infection remain to be fully established. Accordingly, the present study has serologically assessed the co-infection and associated risk factors for Toxoplasma gondii and Toxocara spp. in pregnant women, assisted by the public Unified National Health System (SUS) in southeastern Brazil. Blood samples were collected and tested for IgG antibodies against Toxoplasma gondii by chemiluminescence immunoassay and against Toxocara spp. by enzyme-linked immunosorbent assay (ELISA). An epidemiological questionnaire was applied to gather socioeconomic information to assess the risk factors associated with seropositivity to toxocariasis/toxoplasmosis by univariate analysis followed by logistic regression. Overall, seropositivity was 69/280 (24.6, 95% CI: 19.96-30.01) for T. gondii and 56/280 (20.0, 95% CI: 15.73-25.08) for Toxocara spp. Co-infection was observed in 25/280 (8.9, 95% CI: 6.12-12.85) pregnant women, with increased odds (OR: 3.3, CI 95%: 1.77-6.14, p = 0.0002). Logistic regression revealed that a higher educational level (high school or college) significantly reduced the likelihood of co-infection seropositivity, owning cats increased the odds of toxocariasis, and older pregnant women presented significantly higher T. gondii seropositivity. Co-infection herein highlights the importance of educational programs in the prevention of toxocariasis and toxoplasmosis in pregnant women and other high-risk populations.

Epidemiological and Financial Aspects of Hospitalizations for Bacterial Meningitis in Brazil.

Understanding the epidemiology and cost implications of acute bacterial meningitis is crucial for effective health planning, timely treatment implementation, and comprehensive patient support measures, as well as for determining appropriate hospital expenses. Therefore, we conducted an analysis of hospitalization cases for bacterial meningitis in Brazil from January 2008 to December 2019. This is a descriptive ecological study that utilized the Hospital Information System of Brazil's National Unified Health System (SIH/SUS) database. The variables included sex, region, age group, hospitalizations, deaths, lethality rate, and hospital service expenses. The data were tabulated to focus specifically on the epidemiological aspect of bacterial meningitis. During the study period, there were 20,207 hospitalizations for bacterial meningitis in Brazil. Men accounted for a higher number of cases, with 11,690 (57.67%), while women had a higher lethality rate of 10.64%. The Southeast region had the highest percentage of both hospitalizations (45.78%) and deaths (46.42%). Bacterial meningitis remains an important cause of morbidity and mortality, particularly in children under 5 years of age. Notably, the elderly and the Northeast region showed higher rates of lethality. The total expenditure on hospital services exceeded 43 million in Brazilian real, with the highest expenditure observed in 2019 and the lowest in 2011. A higher prevalence of the disease was observed in males, in children under 1-year-old and in the southeast region. Hospital expenditures were found to be substantial and increasing over time, underscoring the significance of early diagnosis and the promotion of vaccination campaigns.

Primary health care organization in municipalities of São Paulo, Brazil: a model of care aligned with the Brazilian Unified National Health System's guidelines.

This study analyzes the main organization patterns used by primary health care (PHC) services in municipal networks and evaluates them according to indicators of local management-administration interface. Evaluative research analyzed 461 municipalities in São Paulo, Brazil, that participated in the Primary Care Services Quality Assessment Survey (QualiAB) in 2017/2018, classified according to the organizational arrangements composition of 2,472 PHC services. Eight indicators of local management and administration were selected to evaluate the identified patterns. Results indicate two groups of municipalities: homogeneous, with services presenting the same arrangement (43.6%); and heterogeneous, with different arrangements (56.4%). These were subdivided into seven patterns that ranged from homogeneous-traditional, homogeneous-Family Health Strategy, homogeneous-mixed, and different combinations in the heterogeneous group. All indicators showed significant differences between groups (p < 0.001), especially the homogeneous-traditional group, which presented an organizational pattern far from the desired model of a comprehensive and problem-solving PHC. Those integrated with family health units (FHU) and basic health units with community health workers and/or family health teams (BHU/FHU) showed a pattern closer to a comprehensive model - with planning and evaluation actions committed to the local reality and qualification of care. Implementation of federal and state policies are essential for defining the PHC health care model adopted by municipalities.

Prevention, social emancipation, and paradigmatic transition: a 40-year interdisciplinary Brazilian trajectory on accidents and disasters.

The article, in the form of an essay, systematizes a 40-year-long professional trajectory of interdisciplinary and socially engaged experiences around the analysis and prevention of accidents and disasters. This study was mainly developed within the scope of research and postgraduate studies in Public Health in Brazil, driven by the sanitarian movement and the construction of Brazilian Unified National Health System (SUS) in its search for democracy and social and health justices. Its empirical basis involved workers' health and environmental surveillance actions organized in networks led by SUS in conjunction with universities, unions, social movements, environmental nongovernmental organizations (NGO), and Public Prosecutors' Offices. Events of greater socio-environmental complexity in sectors such as steel, petrochemicals, mining, agribusiness, and energy forged the search for new epistemic and interdisciplinary references that encompassed two new justices, i.e., environmental and cognitive. This essay systematizes this trajectory of conceptual contributions in three movements from the 1980s to the present day (each corresponding to a socio-political and institutional context) to reflect on paradigmatic transition movements in the analysis and prevention of accidents and disasters from an interdisciplinary perspective. It ends by suggesting abyssal and emancipatory prevention to face different current crises, including environmental, health, democratic, and civilizing ones.

Regional inequalities in access to hospital birth in the state of Rio de Janeiro, Brazil: travel networks, distance, and time (2010-2019)

Difficult access to birth care services is associated with infant and neonatal mortality and maternal morbidity and mortality. In this study, data from the Brazilian Unified National Health System (SUS) were used to map the evolution of geographic accessibility to hospital birth of usual risk in the state of Rio de Janeiro, Brazil, corresponding to 418,243 admissions in 2010-2011 and 2018-2019. Travel flows, distances traveled, and intermunicipal travel time between the pregnant women's municipality and hospital location were estimated. An increase from 15.9% to 21.5% was observed in the number of pregnant women who needed to travel. The distance traveled increased from 24.6 to 26km, and the travel time from 76.4 to 96.1 minutes, with high variation between Health Regions (HR). Pregnant women living in HR Central-South traveled more frequently (37.4-48.9%), and those living in the HRs Baía da Ilha Grande and Northwest traveled the largest distances (90.9-132.1km) and took more time to get to the hospital in 2018-2019 (96-137 minutes). The identification of municipalities that received pregnant women from many other municipalities and municipalities that treated a higher number of pregnant women (hubs and attraction poles, respectively) reflected the unavailability and disparities in access to services. Regional inequalities and reduced accessibility highlight the need to adapt supply to demand and review the distribution of birth care services in the state of Rio de Janeiro. This study contributes to research and planning on access to maternal and child health services and can be used as a reference study for other states in the country.

Impact of telediagnostics on hospitalizations due to cardiovascular diseases: an approach in municipalities of Bahia State, Brazil

Hospitalization costs due to cardiovascular diseases are high. In 2019, for Bahia State, Brazil, alone, they exceeded BRL 153 million for the Brazilian Unified National Health System, surpassing the costs of cancer hospitalizations. This fact will show an upward trend with the increase in life expectancy in Brazil (7.3 years more by 2060). Introducing new technologies can mitigate the problem. This study analyzes the impact of telediagnostics in electrocardiogram on hospitalizations for cardiovascular diseases in 326 municipalities in Bahia from 2014 to 2020. Diff-in-diff estimator method was used for analysis of the periods before and after the implementation of telediagnostics in Bahia. Results show that the municipalities which introduced the new technology reduced cardiovascular diseases hospitalizations by 6 for each additional year. In the case of families benefiting from the Brazilian Income Transfer Program, the reduction was 3.26 hospitalizations, and 3.08 among municipalities with the specialized service. Hospitalization increase by 7.66 in the 30 to 59 age group and by 5.34 among men for each additional year. Results show a reduction of 1.15 hospitalizations for rheumatologic heart diseases and 1.39 among diabetic people. In terms of ethnicity/color, underreporting was identified in the conditions studied, resulting in more severe prognoses for blacks. Telediagnostics was effective in reducing this inequality by expanding access and reducing hospitalizations, playing a crucial role in public health and impacting mortality reduction. The theme, therefore, deserves further studies with different samples and sample periods.

Social inequalities in indicators of use of healthcare services by adolescents in Campinas, São Paulo, Brazil.

This study aimed to analyze the prevalence of indicators of use of healthcare services according to sex, income and race/skin color, in adolescents (aged 10-19 years old) based on data from the Health Survey of the Municipality of Campinas (ISACamp), carried out in 2014/2015 in Campinas, São Paulo, Brazil. The chi-square test was used to evaluate the differences between the outcome variables (indicators of use of healthcare service) and sex, income and race/skin color. Adjusted prevalence ratios (PR) were estimated using Poisson multiple regression models. The demand for medical care was high in the last year of the interview (79.2%), mostly attended by the Brazilian Unified National Health System (65.2%), with routine consultations being more prevalent for females (PR = 1.17; 95%CI: 1.01-1.34) and injury for the male population (PR = 0.47; 95%CI: 0.26-0.84). Economic and racial differences were found in the evaluation of the last medical consultation, with a higher prevalence of worse care among those with lower income (PR = 1.46; 95%CI: 1.14-1.87) and black people (PR = 1.27; 95%CI: 1.01-1.61). Inequalities remained for delay or failure to carry out exams (PR = 1.64; 95%CI: 1.02-2.64) and worse quality of dental care (PR = 2.10; 95%CI: 1.38-3.21) in those with lower income. Also, black people had fewer appointments with dentists (PR = 0.90; 95%CI: 0.82-0.99).

PERIOPERATIVE CHEMOTHERAPY, ADJUVANT CHEMOTHERAPY AND ADJUVANT CHEMORADIOTHERAPY IN THE SURGICAL TREATMENT OF GASTRIC CANCER IN A HOSPITAL OF THE BRAZILIAN UNIFIED HEALTH SYSTEM.

Despite the preference for multimodal treatment for gastric cancer, abandonment of chemotherapy treatment as well as the need for upfront surgery in obstructed patients brings negative impacts on the treatment. The difficulty of accessing treatment in specialized centers in the Brazilian Unified National Health System (SUS) scenario is an aggravating factor. To identify advantages, prognostic factors, complications, and neoadjuvant and adjuvant therapies survival in gastric cancer treatment in SUS setting. The retrospective study included 81 patients with gastric adenocarcinoma who underwent treatment according to INT0116 trial (adjuvant chemoradiotherapy), CLASSIC trial (adjuvant chemotherapy), FLOT4-AIO trial (perioperative chemotherapy), and surgery with curative intention (R0 resection and D2 lymphadenectomy) in a single cancer center between 2015 and 2020. Individuals with other histological types, gastric stump, esophageal cancer, other treatment protocols, and stage Ia or IV were excluded. Patients were grouped into FLOT4-AIO (26 patients), CLASSIC (25 patients), and INT0116 (30 patients). The average age was 61 years old. More than 60% of patients had pathological stage III. The treatment completion rate was 56%. The pathological complete response rate of the FLOT4-AIO group was 7.7%. Among the prognostic factors that impacted overall survival and disease-free survival were alcoholism, early postoperative complications, and anatomopathological status pN2 and pN3. The 3-year overall survival rate was 64.9%, with the CLASSIC subgroup having the best survival (79.8%). The treatment strategy for gastric cancer varies according to the need for initial surgery. The CLASSIC subgroup had better overall survival and disease-free survival. The INT0116 regimen also protected against mortality, but not with statistical significance. Although FLOT4-AIO is the preferred treatment, the difficulty in carrying out neoadjuvant treatment in SUS scenario had a negative impact on the results due to the criticality of food intake and worse treatment tolerance.

Effects of parliamentary amendments on municipal financing of primary health care in the Brazilian Unified National Health System

This study aims to analyze the effects of the expansion of the federal transfer of parliamentary amendments for municipal financing of primary health care (PHC) in the Brazilian Unified National Health System (SUS), from 2015 to 2020. A longitudinal study was conducted using secondary data on transfers of parliamentary amendments from the Brazilian Ministry of Health and expenditure of municipalities' own resources on public health actions and services and PHC. The effect of the transfer of parliamentary amendments on municipal financing was verified in a stratified way by population size of the municipalities, using generalized estimating equation models. The transfer of parliamentary amendments for PHC showed a large discrepancy in per capita values among municipalities of different population sizes. No correlation with municipal spending on public health actions and services was observed in municipalities with more than 10,000 inhabitants, and the association with spending on PHC (p < 0.050) was inverse in all municipalities. Therefore, the increase in the transfer of parliamentary amendments by the Brazilian Ministry of Health favored a reduction in the allocation of municipal revenues to PHC, which may have been directed to other spending purposes in the SUS. These changes seem to represent priorities established for municipal budget expenditure, which have repercussions on local conditions for guaranteeing stable funding for PHC in Brazil.

A national network of molecular tests to detect Chlamydia trachomatis and Neisseria gonorrhoeae: a pilot implementation experience in Brazil

This study aimed to know the opinion of professionals participating in an experiment to implement a pilot for molecular tests to detect Chlamydia trachomatis and Neisseria gonorrhoeae at the Brazilian Unified National Health System (SUS). The detection rate of C. trachomatis and/or N. gonorrhoeae and the factors associated with infection were determined. The strategy included laboratories belonging to the HIV and viral hepatitis viral load network. Testing targeted people who are more vulnerable to sexually transmitted infections and collected urine samples and/or vaginal, endocervical, and/or male urethral swabs. Questionnaires were sent to state managers and laboratory professionals about the implementation of the pilot. Reviews were overall positive. Weaknesses included difficulties changing work processes, lack of human resources, poorly sensitized care professionals, and absence of primary urine tubes, the only input not provided. Strengths included the centralized acquisition of tests, sharing of equipment, and storage of samples at room temperature. Of the 16,177 people who were tested, 1,004 (6.21%) were positive for C. trachomatis; 1,036 (6.4%), for N. gonorrhoeae; and 239 (1.48%), for C. trachomatis/N. gonorrhoeae . Detection of any infection occurred more frequently in young people (≤ 24 vs. > 24 years) (adjOR = 2.65; 95%CI: 2.38-2.96), men (adjOR = 1.95; 95%CI: 1.72-2.21), brown/black individuals (adjOR = 1.06; 95%CI: 1.05-1.11), those in Southeastern Brazil (adjOR = 1.08; 95%CI: 1.02-1.13), and in urethral secretion samples (adjOR = 1.46; 95%CI: 1.41-1.52). Results show the importance of making testing available nationwide, which supported the implementation of a definitive network to detection C. trachomatis/N. gonorrhoeae in SUS.

Impact of cycling and walking on adiposity and healthcare costs among adults: longitudinal study.

Leisure-time physical activity seems relevant to prevent the development of chronic diseases and obesity. However, not much is known about the economic burden of these healthy behaviors, mainly in longitudinal designs. This study aimed to analyze the impact of walking and cycling on leisure-time on adiposity and healthcare costs among adults. This longitudinal study was conducted at a medium-size Brazilian city and included 198 participants with no missing data attended in the Brazilian Unified National Health System. Cycling and walking were assessed by a questionnaire with a face-to-face interview at four time-points (baseline, 6-month, 12-month, and 18-month). Healthcare costs were assessed using medical records. Adiposity markers included waist circumference and body fatness. Over the follow-up period, participants who were more engaged in cycling presented lower body fatness (p-value = 0.028) and healthcare costs (p-value = 0.038). However, in the multivariate model, the impact of cycling on costs was not significant (p-value = 0.507) due to the impact of number of chronic diseases (p-value = 0.001). Cycling on leisure-time is inversely related to adiposity in adults, whereas its role on preventing chronic diseases seems the main pathway linking it to cost mitigation.

Perception of Health Professionals on the National Health Act, 2014, in University College Hospital, Ibadan

Abstract Background: The National Health Bill was the most debated bill from the legislative arm of government since 1999 and yet, many health professionals are largely unaware of its details. There had been insufficient health legislation establishing a unified national health system in Nigeria, such as provided for in the National Health Act (NHA), 2014, leading to duplication of functions and laws. Health professionals, being key policy actors and at the front line of healthcare, easily notice the impact of policies set by actors in the health-care system. Therefore, their knowledge and perception of the NHA as legitimate, will compel obedience with the provisions of the act, and also create a basis for stronger advocacy for its implementation for the overall strengthening of the health-care system that the act intends to provide a legal framework for. Methodology: This is a descriptive cross-sectional study to assess the perception of health professionals at the University College Hospital, Ibadan, on the NHA, 2014. Participants were selected by a multistage (stratified and then systematic) random sampling technique. Data were collected quantitatively using a self-administered semi-structured questionnaire. The quantitative data were entered and analysed using IBM SPSS version 23. Results: Awareness of the respondents about the Act was good, with up to 75% of respondents being aware of the existence of the NHA Act. However, the knowledge of the content of the Act was poor among all the cadres of health professionals. The differences in awareness among the different cadres of health professionals were statistically significant with the doctors being more aware and the nurses least aware, P = 0.001. The majority of health professionals perceive that the NHA is sufficient to regulate health care and set the appropriate standards in Nigeria. However, the health-care professionals also perceive that Nigerian government is incapable of diligently implementing the provisions of the Act. Conclusion: There is a need for sustained remedial action by health-care professional bodies, organised media, and relevant government ministries and agencies, to ensure that stakeholders, including health professionals, are abreast with the provisions of the NHA, through prioritising health laws as key areas in undergraduate school curricula and continuing medical education on health laws for the practicing health professionals. Good knowledge of the Act will increase the advocacy efforts by the health professionals and other stakeholders towards the implementation of the provisions of the Act by the government and other relevant stakeholders. There is also a need for the government to show more commitment in publicising its effort at the implementation of the Act to improve the poor perception by the health professionals on the government’s ability to implement the provisions of the Act, as seen in this study.

Analysis of the performance of public and private hospitals serving the Brazilian Unified National Health System

This article aims to analyze the performance of the Brazilian Unified National Health System (SUS, acronym in Portuguese) hospital network based on the national databases of the Brazilian Hospital Information System (SIH, acronym in Portuguese) and the Brazilian National Registry of Health Establishments (CNES, acronym in Portuguese). The research used a set of indicators covering the production of admissions, the profile, quality and performance of care, associated with hospital size and legal nature. For data analysis, the Analysis of Variance with Tukey-Kramer test was used to highlight the differences between public and private hospitals, the moderation analysis to verify the effect of hospital size and the Pabon Lasso model to integrate the results. The results show that the increase in the number of beds influences the performance of the indicators differently for public and private hospitals. Public hospitals showed higher gains in scale efficiency with the increase in beds, whereas private non-profit hospitals showed a higher performance in the set of indicators and a more balanced performance in the different sizes. The application of the Pabon Lasso model showed that small hospitals, both public and private, perform poorly. It also showed that from medium-sized onwards, public and private hospitals perform well. However, each category displays particularities in its performance profile, reflecting a diversity of practices and operational results. This study thus confirms previous findings that hospital performance tends to improve as the number of beds increases, but also reveals that it varies significantly depending on the legal nature of these institutions.

Cost-effectiveness study of therapeutic approaches for mucosal leishmaniasis.

This study aimed to estimate the cost-effectiveness of four therapeutic approaches available for mucosal leishmaniasis in Brazil: miltefosine, meglumine antimoniate, combined with and without pentoxifylline, and liposomal amphotericin B. The perspective adopted was that of the Brazilian Unified National Health System (SUS). The outcome of interest was "cured patient", which was analyzed using a decision tree model. Estimates of direct costs and effectiveness were obtained from the scientific literature. Meglumine antimoniate alone was the base comparator strategy; liposomal amphotericin B showed an incremental cost-effectiveness ratio (ICER) of USD 7,409.13 per cured patient, and the combination of meglumine antimoniate with pentoxifylline presented an ICER of USD 85.13. Miltefosine was absolutely dominated, with higher cost and similar effectiveness when compared to meglumine antimoniate. Sensitivity analyses, varying the cost by ±25%, did not change the results. However, when the cost of miltefosine was estimated at less than USD 171.23, this strategy was dominant over meglumine antimoniate alone. The results confirm that treatment with liposomal amphotericin B remains the option with the highest ICER among the approaches analyzed. Miltefosine may be cost-effective based on the variation in the acquisition price, which deserves attention because it is the only available oral option. The non-accounting of other aspects prevent the use of these results immediately to support decision-making, but they point out the need to negotiate the prices of drugs available for mucosal leishmaniasis and indicates the need of encouraging technology transfer or other actions aimed at expanding the performance of the Brazilian national industrial complex.

Adequacy of provision of procedures for early detection of breast cancer in the Brazilian Unified National Health System: a cross-sectional study conducted in Brazil and its regions, 2019

Early detection is a major strategy in breast cancer control and, for this reason, it is important to ensure access to investigation of suspected cases for care continuity and timely treatment. This study aimed to estimate the need for procedures of breast cancer early detection and assess their adequacy for providing care to screened and symptomatic women in the Brazilian Unified National Health System (SUS) in 2019. A descriptive cross-sectional study was conducted to analyze the provision of tests for breast cancer early detection, comparing the estimated need with the procedures performed in the SUS. Parameters provided by the Brazilian National Cancer Institute were used to estimate the population and the need for early detection tests. The number of procedures performed in 2019 was obtained from the Outpatient Information System of the SUS. A deficit in screening mammograms was observed in the country (-45.1%), ranging from -31.4% in the South Region to -70.5 % in the North Region. If this test was offered to the target population, the deficit in the country would reduce to -14.8% and there would be an oversupply in the South Region (6.2%). Diagnostic investigation procedures varied between the regions, with higher deficits in coarse needle biopsy (-90.8%) and breast lump biopsy/excision (-80.6%) observed in the Central-West Region, and the highest deficit in anatomopathological exams in the North Region (-88.5%). The comparison between the production and need for procedures of breast cancer early detection in Brazil and its regions identified deficits and inadequacies that must be better understood and addressed at the state and municipal levels.

Epidemiological intelligence, investment in information technologies and new perspectives for the use of data in health surveillance

In the municipality of Rio de Janeiro, Brazil, the incorporation of the concept of epidemic intelligence and technological resources has supported new perspectives for the use of data by health surveillance, since the COVID-19 pandemic. This article presents the Epidemiological Intelligence Center (CIE) and the tools and products developed in its coordination. The CIE was inaugurated in March 2022, with a multiprofessional team, supported by the premises of transparency and integration of various data sources for early detection of changes in the trends of events of importance in Public Health. The initial acquisition of a data lake favored changes in the consumption, management and security processes for the data processed. This data lake currently stores the Carioca Base - a retrospective cohort of individuals with a history of COVID-19 vaccination and/or events related to the disease. Descriptive and analytical dashboards have been developed and made available, respectively for public use and for health surveillance administrators. An alert panel, aimed at monitoring trends in care in the urgency and emergency network, was implemented and subsidizes rapid response actions in the city's territories. The CIE developed the concept of epidemiological intelligence in the Brazilian Unified National Health System and this paradigm shift was made possible by investments in physical/human resources, the integration of epidemiological, statistical and data science methods, as well as the incorporation of different data sources in data analysis.

Hospital standardized mortality ratio: limits and potential of the indicator for assessing hospital performance in the Brazilian Unified National Health System

Comparative analyses based on clinical performance indicators to monitor the quality of hospital care have been carried out for decades in several countries, most notably the hospital standardized mortality ratio (HSMR). In Brazil, studies and the adoption of methodological tools that allow regular analysis of the performance of institutions are still scarce. This study aimed to assess the use of HSMR to compare the performance of hospitals funded by the Brazilian Unified National Health System (SUS). The Hospital Information System was the source of data on adult hospitalizations in Brazil from 2017 to 2019. The methodological approach to estimate HSMR was adapted to the available data and included the causes of hospitalization (main diagnosis) responsible for 80% of deaths. The number of expected deaths was estimated using a logistic regression model that included predictor variables widely described in the literature. The analysis was conducted in two stages: (i) hospitalization level and (ii) hospital level. The final risk adjustment model showed a C-statistic of 0.774, which is considered adequate. The variation in HSMR was wide, especially among the worst-performing hospitals (1.54 to 6.77). Private hospitals performed better than public hospitals. Although the limits of the available data and the challenges still face its more refined use, HSMR is applicable and has the potential to become an important tool for assessing hospital performance in the SUS.
