  • Vaccination Coverage and Factors Associated With Incomplete Vaccination Schedules in Children Under 5 in a Peripheral Area of the Federal District of Brazil
    Ivea Rayane Mendes Nicacio Viana, Henry Maia Peixoto
    Public Health Nursing, 2026
    Objective To estimate vaccination coverage (VC) and analyze the factors associated with the incomplete vaccination schedule (IVS) in children under 5 years of age in two Basic Health Units in the Federal District of Brazil. Design A cross‐sectional study. Sample The study included 162 children in two Basic Health Units; 54.94% were male, and all were under 5 years of age. Measurements Guardians were interviewed using a structured questionnaire, and their vaccination booklets were photographed. VC was estimated and prevalence ratios (PR) were calculated using Poisson regression analysis. Results Twenty percent of the children had an IVS. None of the vaccines evaluated reached the VC considered correct in terms of age and interval between doses. Factors associated with IVS were age under 2 years (adjusted PR: 2.55; 95% CI: 1.53–4.24), difficulties arising from the COVID‐19 pandemic (adjusted PR: 2.71; 95% CI: 1.51–4.86) and a negative response when asked whether all vaccines were administered in the same location (adjusted PR: 1.97; 95% CI: 1.13–3.44). Conclusions A high proportion of children presented IVS, associated with factors such as age, lack of continuity of vaccination in the same location and difficulties caused by the COVID‐19 pandemic.

    Ana Carolina Esteves da Silva Pereira, Luciana G. Gallo, Ana Flávia de M. Oliveira, Maria Regina F. de Oliveira, Emanuelly Martins da Silva, Henry M. Peixoto
    Brazilian Journal of Infectious Diseases, 2026
    OBJECTIVE: To estimate the costs associated with the hospitalization of patients with Severe Acute Respiratory Infection (SARI) due to SARS-CoV-2 in a university hospital affiliated with the Brazilian Unified Health System (SUS) in 2020 and 2021. METHODS: A bottom-up micro-costing approach was used to conduct a cost analysis based on data from a hospital clinical cohort. Patients with confirmed diagnoses of COVID-19 and SARI, admitted to general wards or intensive care units (with or without mechanical ventilation), were included. Healthcare activities were categorized as hospitalization, ventilation, hemodialysis, nutrition, medications, and laboratory tests. Costs were calculated based on individualized consumption of supplies and procedures, also considering the annualized cost of equipment. Comparisons were made between micro-costing and macro-costing (based on the Hospital Admission Authorizations - AIH). RESULTS: A total of 627 patients were analyzed. The total cost was R$ 5,824,366.73 (Int$ 2,307,593.80) when healthcare professionals were excluded and R$19,437,731.25 (Int$ 7,701,161.35) when they were included. Medications accounted for the largest share (52.79%). Micro-costing was 1.7-times higher than macro-costing for hospital costs alone and 2.3-times higher when professional costs were included. Multivariate analysis identified length of hospital stay as the main factor associated with increased costs, while age, sex, and referral origin showed no significant association. CONCLUSION: This study reveals the substantial economic impact of COVID-19-related hospitalizations in high-complexity care settings. It also highlights the importance of improving financing models for the SUS, particularly given the discrepancies between actual costs and federal reimbursement values. These findings contribute to the development of public policies and response strategies for future health emergencies.

    Brazilian Journal of Physical Therapy, 2026
    BACKGROUND: Low back pain (LBP) is a disabling condition worldwide, and current evidence suggests low rates of referral to physical therapists and extensive use of low-value interventions such as pharmacological treatments and emergency visits. OBJECTIVE: To investigate the frequency of referrals and characterize people with LBP accessing primary care physical therapists, as well as characterize clinical and sociodemographic aspects and the use of health resources in Brazil. METHOD: Observational study using nationwide data on 1,459,710 adults with LBP, stratified according to G1: medical care only, G2: medical care and referral to physical therapist, G3: physical therapist as first contact. Data were analyzed descriptively. RESULTS: 1,405,145 people with LBP were included in G1, followed by G2 (N:14,079), and G3 (N:40,486). The majority was female (56.3 %), and the average age was 49 (±17) years for females and 48 (±17) for males. Less than 1 % (G2) were referred to physical therapists. Of these, 8085 (57.4 %) had an average duration of 17.4 days (±65.6) between referral and their clinical appointment, and 5994 (42.6 %) had a longer duration (261.1 ± 146.9 days). A total of 130,570 (8.9 %) participants were referred for imaging, totaling 152,150 exams. G1 had 105.65 exams/1000 people and 128 referrals to specialists/1000 people. G2 had 196.32 exams and 384.76 referrals to specialists/1000 people, and G3 had 22.87 exams and 64.89 referrals to specialists/1000 people. CONCLUSION: We found a relatively low number of referrals of people with LBP to physical therapists in primary health care in Brazil, and a long period between the referral and the first contact with this professional. In addition, diagnostic imaging and referral to a specialist were frequently used.

    OBJECTIVES: to evaluate the cost-utility of ataluren plus standard of care (SoC) for treating patients with nonsense mutation Duchenne muscular dystrophy from the Brazilian public health system perspective. METHODS: A semi-Markov model, comprising 5 states, was developed to estimate the incremental cost per quality-adjusted life-years (QALYs) of ataluren plus SoC compared with SoC alone. A 48-year time horizon was used in the base-case analysis, considering annual cycles. Costs were expressed as international dollars (Int$) applying the purchasing power parity conversion rate (Brazilian purchasing power parity of 2.44 BRL/Int$ in 2023). The transition probabilities and utility data were obtained from previous studies, and costs were based on data from a microcosting study and the Brazilian Drug Market Regulation Chamber. Both costs and QALYs were discounted using a rate of 5%. Parameter uncertainty was assessed through deterministic and probabilistic sensitivity analyses. RESULTS: Ataluren plus SoC leads to incremental 0.503 QALYs and incremental costs of Int$13 298 877.45, resulting in an incremental cost-utility ratio of Int$26 415 910.08/QALY. According to the deterministic sensitivity analysis, utilities related to the state's health progression of the model were the parameter that most significantly influenced the incremental cost-utility ratio. In the probabilistic sensitivity analysis, all estimates were above the current willingness-to-pay threshold of Int$49 180.33 per QALY for rare diseases. CONCLUSIONS: Ataluren plus SoC for treating nonsense mutation Duchenne muscular dystrophy patients was not a cost-effective intervention compared with SoC alone from the perspective of the Brazilian public health system.

    Expert Review of Pharmacoeconomics and Outcomes Research, 2026
    BACKGROUND: Low back pain (LBP) is a disabling condition affecting all age groups globally. Exercise is safe and cost-effective for managing LBP. Pilates is an effective exercise modality recommended for LBP but is not reimbursed by the Brazilian Public Health System. This study aimed to estimate the budget impact of implementing Pilates for LBP patients within the Brazilian public health system compared to usual care. RESEARCH DESIGN AND METHODS: A budget impact analysis (BIA) was conducted over a five-year horizon, from healthcare and societal perspectives. Costs were extracted in local currency and converted to international dollars using purchasing power parities. Deterministic sensitivity analyses were performed. RESULTS: Over five years, healthcare costs in the usual care were Int$860.8 million, while Pilates reached Int$958 million, resulting in an incremental impact of Int$97.2 million. From the societal perspective, the usual care cost was Int$4.32 billion, and the Pilates scenario was Int$4.15 billion, indicating savings of Int$172.2 million. The incremental budget impact was negative, meaning that Pilates would provide savings of Int$172,203,216. CONCLUSION: Implementing a group-based Pilates program for LBP in the Brazilian public health system would increase healthcare costs by Int$97 million but generate societal savings of Int$172 million over five years.

    Lancet Regional Health Americas, 2025
    Background Vivax malaria requires radical cure to clear both the blood-stage and liver-stage parasites. Brazil, like most endemic countries, has been prescribing a 7-day primaquine regimen for radical cure without testing for glucose-6-phosphate-dehydrogenase (G6PD) deficiency to exclude those at risk of primaquine-induced haemolysis. Tafenoquine, a new single-dose drug for radical cure requires G6PD screening before prescription to ensure safety. This study aims to assess the cost-effectiveness of prescribing tafenoquine after semi-quantitative G6PD screening from the Brazilian Public Health System perspective. Methods A decision tree model was developed for adults presenting with vivax malaria over 12-months. The tafenoquine strategy of semi-quantitative G6PD testing before prescription of single-dose tafenoquine to those with ≥70% G6PD activity was compared with: (1) current practice : 7-day low-dose primaquine (0.5 mg/kg/day) without G6PD screening and (2) primaquine screening strategy: 7-day low-dose primaquine (0.5 mg/kg/day) for patients with ≥30% G6PD activity determined by semi-quantitative G6PD screening. The primary outcome was the cost per disability-adjusted life-year (DALY) averted, compared with the Brazilian willingness-to-pay threshold of US$7752 (R$40,000). Findings The tafenoquine strategy was US$2894 (R$14,934) per DALY averted compared to current practice , well below the willingness-to-pay threshold. The tafenoquine strategy dominated the primaquine screening strategy , averting 0.14 DALYs with cost savings of US$13 (R$66). In both comparisons, the tafenoquine strategy had a >98% likelihood of being cost-effective. Interpretation The prescription of tafenoquine to those who test G6PD normal with a semi-quantitative test is a cost-effective strategy for the radical cure of vivax malaria in Brazil. While the cost-effectiveness in other settings may vary due to differences in costs and the epidemiology of vivax malaria and G6PD deficiency, the robustness of these findings should be reassuring, particularly where healthcare facilities expect to see a large number of patients annually.

    Healthcare Switzerland, 2025
    Background: The advanced access (AA) scheduling model in primary healthcare (PHC) may reduce unnecessary visits to the emergency department (ED). However, evidence of this effect remains uncertain and limited. Objective: To evaluate whether the adoption of AA models in PHC may reduce ED visits, when compared to the traditional model. Methods: A rapid review of the literature according to the World Health Organization’s guidelines was performed, using two databases (PubMed and Lilacs) with articles from 1980 to 2023. Results: A total of 1286 articles were found according to our search. Of them, 1245 were excluded based on their titles, most of them due to not evaluating advanced accesses as an intervention. Of the remaining 41 articles, many did not evaluate ED visits as an outcome, nor did they have the criteria of inclusion. Eight articles evaluated ED visits as an outcome and had inclusion criteria. Five articles were included and three found an association between the adoption of advanced access in PHC and a reduction in ED visits. Conclusion: This review shows that the adoption of AA in PHC may reduce ED visits. However, it is essential to carry out new studies to understand the relationship between the adoption of AA in PHC and its outcomes in universal healthcare systems.

    Cardiac conditions are a significant category of post-COVID conditions. The objective of this study was to synthesise the evidence on the factors associated with the development of post-COVID cardiac conditions, the frequency of clinical outcomes in affected patients, and the potential prognostic factors. A systematic review was conducted using the databases EBSCOhost, MEDLINE via PubMed, BVS, and Embase, covering studies from 2019 to December 2023. A total of 8343 articles were identified, and seven met the eligibility criteria for data extraction. The protective effect of vaccination stood out among the associated factors, showing a reduced risk of developing post-COVID cardiac conditions. Conversely, COVID-19 reinfections were associated with an increased risk of cardiovascular outcomes. Regarding the main outcomes in these patients, most recovered, although some cases persisted beyond 200 days of follow-up. The study included in the analysis of prognostic factors reported that the four children who did not recover by the end of the study were between two and five years old and had gastrointestinal symptoms during the illness. The COVID-19 vaccination regimen reduces the risk of developing post-COVID cardiac conditions. Public health policies promoting immunisation should be encouraged to prevent SARS-CoV-2 infections and reinfections.
  • Dapagliflozin for the treatment of heart failure with reduced ejection fraction in Brazil: a cost-effectiveness analysis
    Marcio Coutinho Xavier Naves, Angelica Amorim Amato, Ivan Ricardo Zimmermann, Henry Maia Peixoto
    Lancet Regional Health Americas, 2025
    Background: Heart failure, a complex clinical syndrome with high morbidity and mortality, has become a significant burden on public health. Recently, a new class of antidiabetic agents-the sodium-glucose cotransporter 2 (SGLT2) inhibitors-was associated with a significant reduction on mortality and hospitalization in HF with reduced ejection fraction (HFrEF) when added to standard pharmacological treatment. Considering the lack of data on its cost-effectiveness, the present study aims to estimate the incremental cost-effectiveness ratio of add-on dapagliflozin treatment for HFrEF from the Brazilian public healthcare system perspective. Methods: We built a Markov model to estimate the clinical outcomes and costs of 1,000 hypothetical subjects with established HFrEF in a lifetime horizon. The model inputs were based on the Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure (DAPA-HF) trial and local data. The main outcome was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life year (QALY) gained. Deterministic and probabilistic sensitivity analyses, as well as scenario analyses, were performed. Findings: The addition of dapagliflozin to standard care treatment in 1,000 HFrEF patients yielded an expected value of 366.99 additional QALYs at an incremental cost of US$ 1,517,878.49, resulting in an ICER of US$ 4,136.08 per QALY gained, being a cost-effective strategy considering the Brazilian official cost-effectiveness threshold (US$ 8,000/QALY). In probabilistic sensitivity analyses, 96.60% of the simulations were also cost-effective. In the scenario analyses, results were similar for individuals with and without diabetes. Interpretation: Dapagliflozin is likely to be cost-effective when added to standard HFrEF therapy in Brazil. Funding: This study was supported by the National Institute of Science and Technology for Health Technology Assessment (Instituto de Avaliação de Tecnologias em Saúde-IATS).
