RESUMEN

In this study, we aimed to estimate the frequency of premalignant and malignant lesions in endometrial polyps, and to evaluate associated clinical and demographic factors. A literature search was performed in major databases and the gray literature using the terms polyps OR endometrial polyp AND endometrial neoplasms OR endometrial cancer OR endometrial hyperplasia OR malignan*. Studies describing the frequency of premalignant and malignant lesions in endometrial polyps and any clinical or demographic factors associated with malignant lesions extracted using hysteroscopy were considered eligible. Independent investigators selected the studies and extracted the data. A meta-analysis was performed using a random-effects model and meta-regression. We identified 37 studies (comprising 21,057 patients) of endometrial polyps. The prevalence of premalignant and malignant lesions was 3.4% (95% confidence interval [CI], 2.8-4.1; I2, 80.5%). Abnormal uterine bleeding (prevalence ratio [PR], 1.47; 95% CI, 1.27-1.69; I2, 82.4%), menopausal status (PR, 1.67; 95% CI, 1.48-1.89; I2, 78.4%), age >60 years (PR, 2.41; 95% CI, 1.84-3.16; I2, 81.5%), diabetes mellitus (PR, 1.76; 95% CI, 1.43-2.16; I2, 0.0%), systemic arterial hypertension (PR, 1.50; 95% CI, 1.20-1.88; I2, 75.9%), obesity (PR, 1.41; 95% CI:1.13-1.76; I2, 41.2%), and tamoxifen use (PR, 1.53; 95% CI, 1.06-2.21; I2, 0.0%) were associated with endometrial polyp malignancy. However, breast cancer (PR, 0.83; 95% CI, 0.44-1.57; I2, 0.0%), hormonal therapy (PR, 0.93; 95% CI, 0.67-1.30; I2, 31.7%), parity (PR, 0.87; 95% CI, 0.39-1.96; I2, 78.1%), and endometrial polyp size (PR, 1.05; 95% CI, 0.70-1.57; I2, 44.7%) were not associated with malignancy of endometrial polyps. Three of every 100 women with clinically recognized polyps, a condition associated with specific clinical and demographic factors, will harbor premalignant or malignant lesions.

RESUMEN

PURPOSE: To assess the prevalence of medicine use in adults of Brasilia and to elucidate the associated factors. METHODS: A cross-sectional study was conducted with adults (18 to 65 years) living in Brasilia, who were selected using a two-stage probabilistic sampling and interviewed in their home, from February to May 2012. The primary outcome was the use of medicines in the last 7 days. A Poisson regression with robust variance was employed to adjust for covariates following a hierarchical model. RESULTS: The study included 1820 individuals (11% losses), 60% of which were women, and the mean age was 37 ± 12.6 years. The prevalence of drug consumption was 35.7% (95% confidence interval [95%CI]: 33.5%-37.9%). Medicine consumption was significantly higher in women (prevalence ratio [PR] = 1.54; 95%CI: 1.28-1.85); unemployed or retired people (PR = 1.35; 95%CI: 1.15-1.59); people with hypertension (PR = 2.33; 95%CI: 2.00-2.71), diabetes (PR = 1.46; 95%CI: 1.22-1.74), depression (PR = 1.32; 95%CI: 1.13-1.53), or other chronic diseases (PR = 1.50; 95%CI: 1.26-1.79); and study participants who had a recent medical consultation (PR = 1.49; 95%CI: 1.29-1.71). Medication use was significantly higher at older ages. The participants obtained about half of the drugs from the Brazilian public health system, but this access was significantly different according to the economic class. CONCLUSIONS: Medication use was common among adults living in Brasilia and is associated with sex, age, health conditions, and access to healthcare.

RESUMEN

OBJECTIVE: To assess the effects of problem-based learning (PBL) on the learning achievements of pharmacy students. METHODS: We searched for controlled studies that compared PBL to traditional learning in pharmacy courses (graduate and undergraduate) in the major literature databases up to January 2014. Two independent researchers selected the studies, extracted the data, and assessed the quality of the studies. Meta-analyses of the outcomes were performed using a random effects model. RESULTS: From 1,988 retrieved records, five were included in present review. The studies assessed students' impressions about the PBL method and compared student grades on the midterm and final examinations. PBL students performed better on midterm examinations (odds ratio [OR] = 1.46; confidence interval [IC] 95%: 1.16, 1.89) and final examinations (OR = 1.60; IC 95%: 1.06, 2.43) compared with students in the traditional learning groups. No difference was found between the groups in the subjective evaluations. CONCLUSION: pharmacy students' knowledge was improved by the PBL method. Pharmaceutical education courses should consider implementing PBL.

RESUMEN

BACKGROUND: With the growing prevalence of lumbar spinal stenosis, endoscopic surgery, which incorporates techniques such as transforaminal, interlaminar, and unilateral biportal (UBE) endoscopy, is increasingly considered. However, the patient selection criteria are debated among spine surgeons. OBJECTIVE: This study used a polytomous Rasch analysis to evaluate the factors influencing surgeon decision-making in selecting patients for endoscopic surgical treatment of lumbar spinal stenosis. METHODS: A comprehensive survey was distributed to a representative sample of 296 spine surgeons. Questions encompassed various patient-related and clinical factors, and responses were captured on a logit scale graphically displaying person-item maps and category probability curves for each test item. Using a Rasch analysis, the data were subsequently analyzed to determine the latent traits influencing decision-making. RESULTS: The Rasch analysis revealed that surgeons' preferences for transforaminal, interlaminar, and UBE techniques were easily influenced by comfort level and experience with the endoscopic procedure and patient-related factors. Harder-to-agree items included technological aspects, favorable clinical outcomes, and postoperative functional recovery and rehabilitation. Descriptive statistics suggested interlaminar as the best endoscopic spinal stenosis decompression technique. However, logit person-item analysis integral to the Rasch methodology showed highest intensity for transforaminal followed by interlaminar endoscopic lumbar stenosis decompression. The UBE technique was the hardest to agree on with a disordered person-item analysis and thresholds in category probability curve plots. CONCLUSION: Surgeon decision-making in selecting patients for endoscopic surgery for lumbar spinal stenosis is multifaceted. While the framework of clinical guidelines remains paramount, on-the-ground experience-based factors significantly influence surgeons' selection of patients for endoscopic lumbar spinal stenosis surgeries. The Rasch methodology allows for a more granular psychometric evaluation of surgeon decision-making and accounts better for years-long experience that may be lost in standardized clinical guideline development. This new approach to assessing spine surgeons' thought processes may improve the implementation of evidence-based protocol change dictated by technological advances was endorsed by the Interamerican Society for Minimally Invasive Spine Surgery (SICCMI), the International Society for Minimal Intervention in Spinal Surgery (ISMISS), the Mexican Spine Society (AMCICO), the Brazilian Spine Society (SBC), the Society for Minimally Invasive Spine Surgery (SMISS), the Korean Minimally Invasive Spine Society (KOMISS), and the International Society for the Advancement of Spine Surgery (ISASS).

RESUMEN

OBJECTIVE: To assess the effect of hypothermia on mortality of neonates with hypoxic-ischemic encephalopathy in different economic resources settings. METHODS: We searched for randomized controlled trials on MEDLINE, Embase and other databases. Duplicate reviewers selected the studies and extracted data. We calculated meta-analyses of the relative risks (RR) and 95% confidence intervals (95% CI), and used meta-regression to evaluate the gross domestic product per capita influence on hypothermia efficacy. RESULTS: Sixteen studies were included (n = 1889); eight were conducted in lower income countries (n = 662). Hypothermia significantly reduced mortality (RR = 0.77; 95% CI: 0.65-0.92). Meta-regression revealed that hypothermia efficacy does not increase as the gross domestic product per capita rises. CONCLUSIONS: There is enough evidence to support hypothermia as the standard care for hypoxic-ischemic encephalopathy. Evidence from low-resource settings is limited, but hypothermia efficacy was not shown to be associated with better resources countries.

RESUMEN

Proving clinical superiority of personalized care models in interventional and surgical pain management is challenging. The apparent difficulties may arise from the inability to standardize complex surgical procedures that often involve multiple steps. Ensuring the surgery is performed the same way every time is nearly impossible. Confounding factors, such as the variability of the patient population and selection bias regarding comorbidities and anatomical variations are also difficult to control for. Small sample sizes in study groups comparing iterations of a surgical protocol may amplify bias. It is essentially impossible to conceal the surgical treatment from the surgeon and the operating team. Restrictive inclusion and exclusion criteria may distort the study population to no longer reflect patients seen in daily practice. Hindsight bias is introduced by the inability to effectively blind patient group allocation, which affects clinical result interpretation, particularly if the outcome is already known to the investigators when the outcome analysis is performed (often a long time after the intervention). Randomization is equally problematic, as many patients want to avoid being randomly assigned to a study group, particularly if they perceive their surgeon to be unsure of which treatment will likely render the best clinical outcome for them. Ethical concerns may also exist if the study involves additional and unnecessary risks. Lastly, surgical trials are costly, especially if the tested interventions are complex and require long-term follow-up to assess their benefit. Traditional clinical testing of personalized surgical pain management treatments may be more challenging because individualized solutions tailored to each patient's pain generator can vary extensively. However, high-grade evidence is needed to prompt a protocol change and break with traditional image-based criteria for treatment. In this article, the authors review issues in surgical trials and offer practical solutions.

RESUMEN

Personalized care models are dominating modern medicine. These models are rooted in teaching future physicians the skill set to keep up with innovation. In orthopedic surgery and neurosurgery, education is increasingly influenced by augmented reality, simulation, navigation, robotics, and in some cases, artificial intelligence. The postpandemic learning environment has also changed, emphasizing online learning and skill- and competency-based teaching models incorporating clinical and bench-top research. Attempts to improve work-life balance and minimize physician burnout have led to work-hour restrictions in postgraduate training programs. These restrictions have made it particularly challenging for orthopedic and neurosurgery residents to acquire the knowledge and skill set to meet the requirements for certification. The fast-paced flow of information and the rapid implementation of innovation require higher efficiencies in the modern postgraduate training environment. However, what is taught typically lags several years behind. Examples include minimally invasive tissue-sparing techniques through tubular small-bladed retractor systems, robotic and navigation, endoscopic, patient-specific implants made possible by advances in imaging technology and 3D printing, and regenerative strategies. Currently, the traditional roles of mentee and mentor are being redefined. The future orthopedic surgeons and neurosurgeons involved in personalized surgical pain management will need to be versed in several disciplines ranging from bioengineering, basic research, computer, social and health sciences, clinical study, trial design, public health policy development, and economic accountability. Solutions to the fast-paced innovation cycle in orthopedic surgery and neurosurgery include adaptive learning skills to seize opportunities for innovation with execution and implementation by facilitating translational research and clinical program development across traditional boundaries between clinical and nonclinical specialties. Preparing the future generation of surgeons to have the aptitude to keep up with the rapid technological advances is challenging for postgraduate residency programs and accreditation agencies. However, implementing clinical protocol change when the entrepreneur-investigator surgeon substantiates it with high-grade clinical evidence is at the heart of personalized surgical pain management.

RESUMEN

BACKGROUND: A retrospective analysis of deaths registered in the Brazilian Mortality System was conducted to quantify the under-reporting of HIV/AIDS deaths and those misclassified to AIDS-related conditions in the 15-49 years old population in Brazil. METHODS: Death rates for AIDS-related diseases were calculated by age and sex for 1985-2009. Changes in the age-sex-specific death rates over time were used to identify conditions likely to be misclassified AIDS deaths and to quantify the corresponding number of misclassified deaths. Deaths due to ill-defined causes were redistributed across all other natural causes of death. The resulting total number of AIDS deaths was further adjusted for incompleteness of the mortality reporting system. RESULTS: Out of the 28 potential causes of death investigated, five increased in the same distinct age pattern as AIDS: pneumonia, Kaposi's sarcoma, other immunodeficiencies, other septicaemia and toxoplasmosis. 18 490 deaths due to these five causes were recoded to HIV/AIDS from 1985 to 2009. 38 145 deaths due to ill-defined causes were redistributed to AIDS and 15 485 were added to the number of AIDS deaths to correct for completeness of the mortality system in Brazil. Altogether, 72 120 deaths were recoded to AIDS between 1985 and 2009 and added to the reported 194 445 AIDS related deaths in the country, representing 27% misclassification of AIDS deaths in Brazil. CONCLUSIONS: This study demonstrated that AIDS mortality is underestimated by the official mortality information system in Brazil. Efforts need to be made to reduce misclassification of causes of death in the future and identify ways in which the confidentiality of information regarding cause of death can be maintained.

RESUMEN

OBJECTIVES: The aim of this study was to summarize and assess economic evaluations of poison centers (PCs) from the perspectives of society, the payer, and the healthcare system. METHODS: A systematic review was performed to identify complete economic evaluations regardless of the language or publication status. Two reviewers evaluated the abstracts for eligibility, extracted the data, and assessed the study quality using a standardized tool. RESULTS: In total, 422 non-duplicated studies were retrieved, but only nine met the eligibility criteria. Five of the eligible studies were published in the 1990s, and four were published in the 2000s. Six studies met at least seven of ten quality criteria. In all studies, the presence of PCs was compared with a scenario of their absence. Eight studies used cost-benefit analyses and one used a cost-effectiveness approach. The cost-benefit ratios ranged from 0.76 to 7.67, which indicates that each United States dollar (USD) spent on poison centers can save almost 8 USD on medical spending. A cost-effectiveness analysis showed that each successful outcome achieved by a PC avoids a minimum of 12,000 USD to 56,000 USD in other healthcare spending. CONCLUSIONS: The data in our review show that PCs are economically viable. PCs improve the efficiency of healthcare expenditure and contribute to the sustainability of the healthcare system. An investment in PCs is a rational public health policy approach that contrasts the current trend of reducing spending on PCs.

RESUMEN

A systematic review and meta-analysis were conducted to evaluate the benefit of an axillary surgical approach on overall survival and secondarily of breast surgery amongst patients with metastatic breast cancer which is considered to be an incurable disease. However, an axillary surgical approach showed no association with overall survival in patients with metastatic breast cancer. The true impact of locoregional therapies on long-term outcomes remains unknown, and randomised clinical trials are needed.

RESUMEN

INTRODUCTION: Chronic rhinosinusitis can lead to poor sleep quality in affected individuals. Endoscopic nasal surgery has been indicated for patients with chronic rhinosinusitis, resulting in improved quality of life, but it is still unknown if there is a similar improvement in sleep quality after the surgical procedure. OBJECTIVE: To estimate the sleep quality of patients with chronic rhinosinusitis after undergoing endoscopic sinus surgery. METHODS: The literature search was conducted in the indexed databases PubMed, Embase, Lilacs, SciELO, Google Scholar, Web of Science, Scopus, Database of Thesis and Dissertations of CAPES, Cochrane Library, Clinical Trials and in the grey literature. It included studies that reported the sleep quality of patients with chronic rhinosinusitis after undergoing endoscopic sinus surgery based on questionnaires assessing quality of life. Two researchers independently conducted the study selection and extraction. The random effects model was chosen to conduct the meta-analysis that was performed using the statistical package STATA, version 11. RESULTS: Overall, 4 studies and 509 subjects were included in the systematic review. Improved sleep quality was observed in 90% of the patients. There was an improvement (on average, from 57% to 67%) in each of the five symptoms related to sleep quality. The results of the meta-analysis revealed high heterogeneity. CONCLUSIONS: This review shows that a large percentage of patients report improved sleep quality after endoscopic sinus surgery.

RESUMEN

OBJECTIVES: To estimate the prevalence of multimorbidity and to identify factors associated with it in the adult population from the metropolitan region of Manaus. DESIGN: Cross-sectional population-based study. SETTING: Interviews conducted between May and August of 2015 in eight cities that compose the metropolitan region of Manaus, Amazonas, Brazil. PARTICIPANTS: 4001 adults aged ≥18 years. PRIMARY OUTCOME MEASURES: Multimorbidity, measured by the occurrence of ≥2 and ≥3 chronic diseases, was the primary outcome. The associated factors were investigated by calculating the prevalence ratio (PR) obtained by Poisson regression, with robust adjustment of the variance in a hierarchical model. A factor analysis was conducted to investigate multimorbidity clusters. RESULTS: Half of the interviewees were women. The presence of a chronic disease was reported by 57.2% (95% CI 56.6% to 59.7%) of the interviewees, and the mean morbidity was 1.2 (1.1-1.2); 29.0% (95% CI 27.6% to 30.5%) reported ≥2 morbidities and 15.2% (95% CI 14.1% to 16.4%) reported ≥3 chronic conditions. Back pain was reported by one-third of the interviewees. Multimorbidity was highest in women, PR=1.66 (95% CI 1.50 to 1.83); the elderly, PR=5.68 (95% CI 4.51 to 7.15) and individuals with worse health perception, PR=3.70 (95% CI 2.73 to 5.00). Associated factors also included undergoing medical consultations, hospitalisation in the last year, suffering from dengue in the last year and seeking the same healthcare service. Factor analysis revealed a pattern of multimorbidity in women. The factor loading the most strength of association in women was heart disease. In men, an association was identified in two groups, and lung disease was the disease with the highest factorial loading. CONCLUSION: Multimorbidity was frequent in the metropolitan region of Manaus. It occurred most often in women, in the elderly and in those with worse health perception.

RESUMEN

BACKGROUND: The comparison between long acting insulin analogues (LAIA) and human insulin (NPH) has been investigated for decades, with many randomized controlled trials (RCTs) and systematic reviews giving mixed results. This overlapping and contradictory evidence has increased uncertainty on coverage decisions at health systems level. AIM: To conduct an overview of systematic reviews and update existing reviews, preparing new meta-analysis to determine whether LAIA are effective for T1D patients compared to NPH. METHODS: We identified systematic reviews of RCTs that evaluated the efficacy of LAIA glargine or detemir, compared to NPH insulin for T1D, assessing glycated hemoglobin (A1C) and hypoglycemia. Data sources included Pubmed, Cochrane Library, EMBASE and hand-searching. The methodological quality of studies was independently assessed by two reviewers, using AMSTAR and Jadad scale. We found 11 eligible systematic reviews that contained a total of 25 relevant clinical trials. Two reviewers independently abstracted data. RESULTS: We found evidence that LAIA are efficacious compared to NPH, with estimates showing a reduction in nocturnal hypoglycemia episodes (RR 0.66; 95% CI 0.57; 0.76) and A1C (95% CI 0.23; 0.12). No significance was found related to severe hypoglycemia (RR 0.94; 95% CI 0.71; 1.24). CONCLUSION: This study design has allowed us to carry out the most comprehensive assessment of RCTs on this subject, filling a gap in diabetes research. Our paper addresses a question that is important not only for decision makers but also for clinicians.

RESUMEN

OBJECTIVE: To estimate the sensitivity and specificity of self-reported hypertension (HTN) as compared with the clinical diagnosis in epidemiological studies. METHODS: We searched MEDLINE, Embase, Scopus, Web of Science, LILACS, Google Scholar, and ProQuest Dissertations & Theses Global: Health & Medicine databases. In addition, we screened the references' lists of relevant reports to identify potentially eligible articles. There were no date or language restrictions. Studies were selected by two independent reviewers, who also extracted data and assessed methodological quality using the Quality Assessment of Diagnostic Accuracy Studies criteria. A meta-analysis was performed to summarize sensitivity and specificity across studies and estimate heterogeneity. RESULTS: Out of 2304 records, 22 were included, corresponding to a population of 112 517 adults (55% women). There was substantial variation in sensitivity and specificity across countries and age groups. Several different techniques, devices, and reference ranges were used to diagnose HTN, and self-reporting underestimated its prevalence in the majority of studies. The sensitivity was 42.1% (95% confidence interval 30.9-54.2) and the specificity was 89.5% (95% confidence interval 84.0-93.3), with high heterogeneity (I > 99%). CONCLUSION: Less than half of patients with HTN would not be identified by self-reporting in epidemiological studies. Self-reported HTN has important limitations and may represent an important source of bias in research depending on regional, socioeconomic, and cultural differences.

RESUMEN

OBJECTIVE: To systematically analyze the relationship between maternal anemia and low birth weight. METHODS: A search of studies was conducted in the main databases (Medline, Embase, Scopus, Web of Science, SciELO, and Lilacs), the gray literature, and the reference lists of selected articles. Cohort and case-control studies that met the eligibility criteria were included in the review. There was no limitation on the language or date of publication. Article selection and data extraction were performed by two independent reviewers. Meta-analyses with random effects, subgroup analyses and meta-regressions were performed. Publication bias was measured using Egger regression and visual funnel plot inspection. RESULTS: A total of 7243 articles were found, of which 71 comprised the systematic review and 68 were included in the meta-analyses. Maternal anemia was associated with low birth weight with an adjusted OR: 1.23 (95% CI: 1.06⁻1.43) and I²: 58%. The meta-regressions confirmed that the sample size and the methodological quality may partially explain the statistical heterogeneity. CONCLUSIONS: Maternal anemia was considered a risk factor for low birth weight.

RESUMEN

OBJECTIVE: To assess and compare quality of abstracts presented at a medical congress (XIV Congresso da Sociedade Brasileira de Infectologia, November, 2005). The hypothesis is that material of better quality is chosen for oral presentation. METHODS: All the 63 abstracts selected for oral presentation were compared with a random sample (n=63) of the 664 abstracts registered as poster presentations. Quality was measured by a structured questionnaire comprised of 33 criteria, distributed in eight categories: purpose, research design, setting, subjects, intervention, measurement, results and conclusions. The questionnaire was applied by one of the authors who were not blind to the objective of the study. The final score could range from 0 (bad) to 1 (excellent). RESULTS: Abstracts quality was considered moderately good. The overall mean quality scores were 0.60 and 0.62 respectively, for poster and oral presentation (p = 0.086). The criteria rated poorly were: subjects, variable measurements, location and conclusion. CONCLUSIONS: The tested hypothesis of better quality in abstracts selected for oral presentation has not been confirmed. It is recommended that organizers of the congresses the use of objective quality criteria to select the form of presentation while improving on quality.

RESUMEN

OBJECTIVE:: To estimate and compare the effect of self-reported long-term health conditions and sociodemographic factors on perceived health-related quality of life (HRQoL). METHODS:: A population-based survey of adults (18 to 65 years) living in Brasilia, Brazil, was conducted in 2012. Descriptive and multivariate analyses using a Tobit model were performed with data on sociodemographic variables, self-reported conditions, and the European Quality of Life-5 Dimensions (EQ-5D) health states, providing utility scores (preferred health state) between 0 and 1 for HRQoL estimates. RESULTS:: The mean utility of 1,820 adults interviewed (mean age: 38.4±12.6 years) was 0.883 (95% confidence interval [95%CI] 0.874-0.892), with 76.2% in the highest utility range (0.8 to 1.0). EQ-5D dimensions with moderate problems were pain/discomfort (33.8%) and anxiety/depression (20.5%). Serious problems were reported by only 0.3% of the sample in the mobility and self-care domain and by 3.1% in the pain/discomfort domain. Multivariate analysis revealed reduced HRQoL in individuals with depression, diabetes, and hypertension. Living in satellite towns (outside the city core), belonging to a lower economic class, or not being formally employed were also associated with decreased HRQoL. Beta coefficients for these impacts ranged from -0.033 (not formally employed) to -0.141 (depression), reflecting the strongest impact. CONCLUSION:: Of the long-term health conditions studied, depression had the greatest impact on HRQoL. Social class, employment status, and place of residence also affected HRQoL.

RESUMEN

OBJECTIVES: To estimate the prevalence of healthcare use and associated factors in the Manaus metropolitan region and to describe the reasons for lack of access. DESIGN: Cross-sectional population-based study. SETTING: A survey conducted between May and August of 2015 in eight cities from Manaus metropolitan region, Amazonas, Brazil. PARTICIPANTS: 4001 adults ≥18 years of age. PRIMARY OUTCOMES MEASURES: Physician visits, dentist visits and hospitalisations in the last 12 months were the primary outcomes. Associated factors were investigated through the calculation of prevalence ratio (PR) obtained by hierarchical Poisson regression modelling. RESULTS: 4001 adults were included in the study, 53% of whom were women. The self-reported prevalence of medical visits was 77% (95% CI 75% to 77%); dentist visits, 36% (95% CI 34% to 37%) and hospital admission, 7% (95% CI 6% to 7%). Physician visits were higher in women PR=1.18 (95% CI 1.14 to 1.23), the elderly PR=1.18 (95% CI 1.10 to 1.26) and people with health insurance PR=1.14 (95% CI 1.10 to 1.19). Dentist visits declined with older age PR=0.38 (95% CI 0.30 to 0.49), lower education level PR=0.62 (95% CI 0.51 to 0.74) and lower economic class PR=0.65 (95% CI 0.57 to 0.75). Hospitalisations were found to be twice as frequent for women than for men and three times as frequent among those who reported very poor health status. Among the individuals who did not receive medical attention in the previous 2 weeks, 58% reported lack of facilities or appointment unavailable and 14% reported lack of doctors. CONCLUSION: While more than half visited the doctor in the last year, a lower proportion of people with socioeconomic inequities visited the dentist. Organisational and service policies are needed to increase equity in health services in the region.

RESUMEN

BACKGROUND: Long-acting insulin analogues for type 1 diabetes (T1D) treatment have been available on the Brazilian market since 2002. However, the population cannot access the analogues through the public health system. OBJECTIVE: To estimate the incremental budget impact of long-acting insulin analogues coverage for T1D patients in the Brazilian public health system compared to NPH insulin. METHODS: We performed a budget impact analysis of a five-year period. The eligible population was projected using epidemiological data from the International Diabetes Federation estimates for patients between 0-14 and 20-79 years old. The prevalence of T1D was estimated in children, and the same proportion was applied to the 15-19-year-old group due to a gap in epidemiological information. We considered 4,944 new cases per year and a 34.61/100,000 inhabitants mortality rate. Market share for long-acting insulin analogues was assumed as 20% in the first year, reaching 40% in the fifth year. The mean daily dose was taken from clinical trials. We calculated the bargaining power of the Ministry of Health by dividing the price paid for human insulin in the last purchase by the average regulated price. We performed univariate and multivariate sensitivity analyses. RESULTS: The incremental budget impact of long-acting insulin analogues was US$ 28.6 million in the first year, and reached US$ 58.7 million in the fifth year. The total incremental budget impact was US$ 217.9 million over the five-year period. The sensitivity analysis showed that the percentage of T1D among diabetic adults and the insulin analogue price were the main factors that affected the budget impact. CONCLUSIONS: The cost of the first year of long-acting insulin analogue coverage would correspond to 0.03% of total public health expenditure. The main advantage of this study is that it identifies potential bargaining power because it features more realistic profiles of resource usage, once centralized purchasing is established as an economically sustainable strategy. Clinical guidelines restricting the use of insulin analogues would make the decision towards insulin analogue coverage more affordable.
