Análise de impacto orçamentário de dispositivos contraceptivos na saúde suplementar brasileira / Budget impact analysis of contraceptive devices on Brazilian supplementary health

Objetivo: Analisar o impacto orçamentário da adoção de dispositivos contraceptivos reversíveis de longa duração em uma operadora de plano de saúde localizada no Sul do Brasil. Especificamente, analisamos a incorporação do implante subdérmico de etonogestrel (Implanon®) como alternativa ao sistema intrauterino de levonorgestrel (DIU Mirena® ou DIU Kyleena®), ao longo de um período de 15 anos. Métodos: Realizamos uma análise do impacto orçamentário incremental, considerando a inclusão gradual do implante subdérmico de etonogestrel. Foram considerados dados de uma operadora de planos de saúde com mais de 600.000 beneficiários. O horizonte temporal de 15 anos permitiu uma avaliação abrangente dos efeitos financeiros. Resultados: Identificamos 5.345 pacientes elegíveis para a utilização de contraceptivos reversíveis de longa duração. No cenário em que somente o sistema intrauterino de levonorgestrel era adotado, projetou-se um impacto orçamentário total de R$ 746.379.857,80 ao longo de 15 anos. No cenário alternativo, com a incorporação gradual do implante subdérmico, o impacto orçamentário total foi calculado em R$ 689.800.196,83. Isso resultou em um impacto orçamentário incremental negativo de -R$ 56.579.660,97 ao longo do período. Conclusão: A análise de impacto orçamentário realizada indica um potencial benefício financeiro ao adotar o implante subdérmico de etonogestrel como alternativa ao sistema intrauterino de levonorgestrel para contracepção. Esse achado sugere possíveis reduções de custos na área de saúde suplementar no Brasil, reforçando a importância de avaliar opções economicamente viáveis.

Objective: To analyze the budgetary impact of the adoption of long-acting reversible contraceptive devices in a health plan operator located in southern Brazil. Specifically, we analyzed the incorporation of the etonogestrel subdermal implant (Implanon®) as an alternative to the levonorgestrel intrauterine system (Mirena® IUD or Kyleena® IUD), over a period of 15 years. Methods: We performed an analysis of the incremental budgetary impact, considering the gradual inclusion of the etonogestrel subdermal implant. Data from a health plan operator with more than 600,000 beneficiaries were considered. The 15-year time horizon allowed for a comprehensive assessment of the financial effects. Results: We identified 5,345 patients eligible for the use of long-acting reversible contraceptives. In the scenario where only the levonorgestrel intrauterine system was adopted, a total budget impact of BRL 746,379,857.80 was projected over 15 years. In the alternative scenario, with the gradual incorporation of the subdermal implant, the total budgetary impact was calculated at BRL 689,800,196.83. This resulted in a negative incremental budgetary impact of -R$56,579,660.97 over the period. Conclusion: The budget impact analysis carried out indicates a potential financial benefit in adopting the etonogestrel subdermal implant as an alternative to the levonorgestrel intrauterine system for contraception. This finding suggests possible cost reductions in the supplementary healthcare area in Brazil, reinforcing the importance of evaluating economically viable options.

COVID-19 in real world: Survival and medical costs of hospitalized patients in Brazils first wave

ABSTRACT Objective: To evaluate survival and direct medical costs of patients admitted in private hospitals with COVID-19 during the first wave. Methods: A retrospective, observational study analyzing survival and the economic data retrieved on hospitalized patients with COVID-19. Data from March 2020 to December 2020. The direct cost of hospitalization was estimated using the microcosting method with each individual hospitalization. Results: 342 cases were evaluated. Median age of 61.0 (95% CI 57.0-65.0). 194 (56.7%) were men. The mortality rate was higher in the female sex (p = 0.0037), ICU (p < 0.001), mechanical ventilation (p<0.001) and elderly groups. 143 (41.8%) patients were admitted to the ICU (95% CI 36.6%-47.1%), of which 60 (41.9%) required MV (95% CI 34.0%-50.0%). Global LOS presented median of 6.7 days (95% CI 6.0-7.2). Mean costs were US$ 7,060,00 (95% CI 5,300.94-8,819,00) for each patient. Mean cost for patients discharged alive and patients deceased was US$ 5,475.53 (95% CI 3,692.91-7,258.14) and US$ 12,955.19 (95% CI 8,106.61 -17,803.76), respectively (p < 0.001). Conclusions: Patients admitted with COVID-19 in these private hospitals point to great economic impact, mainly in the elderly and high-risk patients. It is key to better understand such costs in order to be prepared to make wise decisions during the current and future global health emergencies.

Elective surgeries in the new normal post-COVID-19 pandemic: to test or do not test? / Cirurgias eletivas no novo normal pós-pandemia da COVID-19: testar ou não testar?

ABSTRACT The new coronavirus (SARS-CoV-2) pandemic has been wreaking havoc all over the planet. In a precautionary measure, populations have been forced and kept under quarantine to contain the outbreak of the COVID-19 disease. The quarantine primary goal is to avoid the overload to the hospitals, which should be available for the care of COVID-19 patients. However, the virus does not have a uniform spread throughout the planet, and Brazil is no different. Although all the world's attention is now on the COVID-19 pandemic, there is no similar pattern of spread, and other diseases are still a real problem. Given the risks of transmission between patients and healthcare providers, there is a great challenge for healthcare institutions who must balance resources to assure safe care to patients and professionals while they take care of other disease patients, and perform surgical procedures that need to be carried out. Under such circumstances, as COVID-19 can also present pre- or asymptomatic transmission, it can be challenging to identify patients who are carrying and spreading the virus. Studies and information on mandatory testing for who are candidates to undergo elective surgery are scarce. Thus, the authors have reviewed the literature, and discuss the need to test these patients under the current context.

RESUMO A pandemia do novo coronavírus (SARS-CoV-2) vem causando estragos em todo o planeta. As populações estão sendo forçadas a quarentena - e assim mantidas - como medida de precaução para conter o surto da doença COVID-19. O principal objetivo da quarentena é evitar a sobrecarga dos hospitais, o que pode ser determinante para o atendimento aos pacientes COVID-19. O vírus não tem propagação uniforme pelo planeta, e no Brasil não é diferente. Contudo, as pessoas continuam a adoecer por outras causas não relacionadas ao SARS-CoV-2, demandando atendimento médico-hospitalar. Assim, os governos estão avaliando e liberando regiões para a realização de cirurgias eletivas em Estados e Municípios onde a COVID-19 está sob controle. Nesse contexto, há preocupação inerente à transmissão SARS-CoV-2 entre pacientes e prestadores de serviços de saúde, uma vez que há poucas informações sobre testes obrigatórios a serem realizados em pacientes com indicação cirúrgica. Esse problema é causado principalmente porque todos os pacientes durante o período de incubação são assintomáticos e, portanto, difíceis de serem avaliados. Assim sendo, os autores avaliam a literatura pertinente à microbiologia do SARS-CoV-2 e discutem a necessidade de testar esses pacientes com testes mais utilizados até o momento.

Early switch/early discharge opportunities for hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Brazil

ABSTRACT Background: Early antibiotic switch and early discharge protocols have not been widely studied in Latin America. Our objective was to describe real-world treatment patterns, resource use, and estimate opportunities for early switch from intravenous to oral antibiotics and early discharge for patients hospitalized with methicillin-resistant Staphylococcus aureus complicated skin and soft-tissue infections. Materials/methods: This retrospective medical chart review recruited 72 physicians from Brazil to collect data from patients hospitalized with documented methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections between May 2013 and May 2015, and discharged alive by June 2015. Data collected included clinical characteristics and outcomes, hospital length of stay, methicillin-resistant Staphylococcus aureus-targeted intravenous and oral antibiotic use, and early switch and early discharge eligibility using literature-based and expert-validated criteria. Results: A total of 199 patient charts were reviewed, of which 196 (98.5%) were prescribed methicillin-resistant Staphylococcus aureus -active therapy. Only four patients were switched from intravenous to oral antibiotics while hospitalized. The mean length of methicillin-resistant Staphylococcus aureus-active treatment was 14.7 (standard deviation, 10.1) days, with 14.6 (standard deviation, 10.1) total days of intravenous therapy. The mean length of hospital stay was 22.2 (standard deviation, 23.0) days. The most frequent initial methicillin-resistant Staphylococcus aureus-active therapies were intravenous vancomycin (58.2%), intravenous clindamycin (19.9%), and intravenous daptomycin (6.6%). Thirty-one patients (15.6%) were discharged with methicillin-resistant Staphylococcus aureus -active antibiotics of which 80.6% received oral antibiotics. Sixty-two patients (31.2%) met early switch criteria and potentially could have discontinued intravenous therapy 6.8 (standard deviation, 7.8) days sooner, and 65 patients (32.7%) met early discharge criteria and potentially could have been discharged 5.3 (standard deviation, 7.0) days sooner. Conclusions: Only 2% of patients were switched from intravenous to oral antibiotics in our study while almost one-third were early switch eligible. Additionally, one-third of hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections were early discharge eligible indicating opportunity for reducing intravenous therapy and days of hospital stay. These results provide insight into possible benefits of implementation of early switch/early discharge protocols in Brazil.

Risk factors for mortality in patients with ventilator-associated pneumonia caused by carbapenem-resistant Enterobacteriaceae

Abstract Background: The ideal therapeutic option for ventilator associated pneumonia caused by carbapenem-resistant Enterobacteriaceae is not defined. The aim of this study was to assess mortality-associated risk factors in patients with VAP by CRE and determine the outcome of several treatment options. Methods: This was a retrospective study performed in two tertiary hospitals involving patients with VAP caused by CRE between January 2010 and August 2014. The outcomes were mortality within 30 days of VAP diagnosis and overall mortality during hospital admission. Risk factors for mortality were assessed by comparing variables of survivors and non-survivors. Results: One hundred and twelve patients with CRE-VAP were included, 73 (65%) male, median age 56 years. The 30-day mortality was 57.1% and the overall hospital mortality was 67%. In the binary logistic regression analysis, only age >50 years was independently associated to increased mortality. Polymyxin was the most used drug (47.5%), followed by tigecycline (29.2%) and aminoglycosides (2.4%). Combined therapy with two active drugs was used by 17 patients (20.8%). No therapeutic option was independently associated to survival. However, combined therapy with two active drugs was superior to the therapy with a single active drug when inappropriate therapy was the comparator (p = 0.044). The addition of carbapenem was not associated with increased survival. Conclusion: The best therapeutic option for VAP by CRE is still not completely defined, but the therapy with at least two active drugs was superior in this study.

Clinical, imagiological and etiological spectrum of posterior reversible encephalopathy syndrome / Espectro clínico, imagiológico e etiológico da síndrome de encefalopatia posterior reversível

Objective Analyze the cases of posterior reversible encephalopathy syndrome (PRES) admitted in a Neurology Department during an 8-year period. Method Retrospective observational study in a central hospital in the north of Portugal. Results 14 patients were identified, mean age 52.3 years. Precipitating factors included: eclampsia, isolated arterial hypertension, spinal trauma and autonomic dysreflexia, Guillain-Barré syndrome, sepsis, sarcoidosis and pulmonary cryptococcosis and drugs. Most patients presented posterior-predominant vasogenic edema lesions, however 64.2% presented frontal lesions and in 42.8% cerebellum was involved. Four patients also had acute ischemic lesions and 1 had hemorrhagic lesions. During follow-up 10 patients recovered fully, 2 recovered partially, 1 suffered a recurrence and 2 died in hospital. Conclusion PRES has many etiological factors. The terms posterior and reversible should be revised because PRES frequently involves other brain regions and it is not always reversible. PRES patients may develop life-threatening complications and mortality is not negligible. .

Objetivo Análise dos casos de síndrome de encefalopatia posterior reversível (PRES) internados em um Serviço de Neurologia durante oito anos. Método Estudo restrospectivo observacional num hospital central do norte de Portugal. Resultados Identificaram-se 14 casos, idade média de 52,3 anos. Os factores precipitantes foram: eclâmpsia, hipertensão arterial isolada, traumatismos vertebro-medulares com disfunção autonómica, síndrome de Guillain-Barré, sépsis, sarcoidose e criptococose pulmonar e fármacos. A maioria dos doentes apresentou lesões edematosas de predomínio posterior, contudo 64,2% apresentaram lesões frontais e 42,8% apresentaram também lesões cerebelosas. Quatro doentes tinham lesões isquémicas agudas e um apresentou lesões hemorrágicas. Durante o seguimento, 10 doentes recuperaram totalmente, 2 recuperaram com sequelas, 1 teve recidiva e 2 faleceram durante o internamento. Conclusão A PRES apresenta muitos factores precipitantes. As designações posterior e reversível deverão ser reequacionadas dado que a PRES afecta outras zonas do cérebro e nem sempre é reversível, apresentado complicações e mortalidade não ...

A simple mathematical model to determine the ideal empirical antibiotic therapy for bacteremic patients

BACKGROUND: Local epidemiological data are always helpful when choosing the best antibiotic regimen, but it is more complex than it seems as it may require the analysis of multiple combinations. The aim of this study was to demonstrate a simplified mathematical calculation to determine the most appropriate antibiotic combination in a scenario where monotherapy is doomed to failure. METHODS: The susceptibility pattern of 11 antibiotics from 216 positive blood cultures from January 2012 to January 2013 was analyzed based on local policy. The length of hospitalization before bacteremia and the unit (ward or intensive care unit) were the analyzed variables. Bacteremia was classified as early, intermediate or late. The antibiotics were combined according to the combination model presented herein. RESULTS: A total of 55 possible mathematical associations were found combining 2 by 2, 165 associations with 3 by 3 and 330 combinations with 4 by 4. In the intensive care unit, monotherapy never reached 80% of susceptibility. In the ward, only carbapenems covered more than 90% of early bacteremia. Only three drugs combined reached a susceptibility rate higher than 90% anywhere in the hospital. Several regimens using four drugs combined reached 100% of susceptibility. CONCLUSIONS: Association of three drugs is necessary for adequate coverage of empirical treatment of bacteremia in both the intensive care unit and the ward. .

Risk factors for KPC-producing Klebsiella pneumoniae bacteremia

The molecular epidemiology of carbapenemase-producing Klebsiella pneumoniae (KPC) has been largely investigated, but limited clinical information is available. A case-control study was performed to evaluate the risk factors for KPC bacteremia in hospitalized patients. Cases were patients with KPC bacteremia and controls were patients with non-KPC bacteremia. A total of 85 patients were included, 18 (21.2%) were KPC, and 67 (78.8%) were non-KPC (40 [59.7%] of them were extended-spectrum beta-lactamase producers). All KPC isolates were type 2 producers. These isolates belong to five distinct clones. Multivariate analysis showed that age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.02 - 1.11; p = 0.004), presence of mechanical ventilation (OR, 11.1; 95% CI, 1.92 - 63.3; p = 0.007) and fluoroquinolone exposure during hospitalization (OR, 28.9; 95% CI, 1.85 - 454.6; p = 0.02) were independent risk factors for KPC in patients with K. pneumoniae bacteremia. Factors associated with severity of illness, such as age and mechanical ventilation, seem to be the main risks factors for KPC. Fluoroquinolones use might be a risk factor for KPC bacteremia. Further investigations on risk factors for KPC are warranted.

Risk factors for pan-resistant Pseudomonas aeruginosa bacteremia and the adequacy of antibiotic therapy

INTRODUCTION: The aim of this study was to determine risk factors for acquiring carbapenemresistant Pseudomonas aeruginosa bacteremia (CR-PA) and factors associated with in-hospital mortality. METHODS: Seventy-seven cases of bacteremia caused by P. aeruginosa were evaluated in a hospital with high incidence of CR-PA. Clinical and laboratorial factors, and previous use of antibiotics were also evaluated. In one analysis, CR-PA and carbapenem-susceptible P. aeruginosa (CS-PA) bacteremia were compared. A second analysis compared patients who died with survivors. RESULTS: Among 77 P. aeruginosa bacteremia, 29 were caused by CR-PA. Admission to the intensive care unit, higher number of total leukocytes, and previous use of carbapenem were statistically associated with CR-PA. In the multivariate analysis, only previous use of carbapenem (including ertapenem) turned out to be a risk factor for CR-PA (p = 0.014). The 30-day mortality of patients with P. aeruginosa bloodstream infection was 44.8% for CS-PA and 54.2% for patients with CR-PA (p = 0.288). Chronic renal failure, admission to the intensive care unit, mechanical ventilation, and central venous catheter were risk factors for mortality. Incorrect treatment increased mortality of patients with bacteremia caused by CS-PA, but not for CR-SA. The odd ratio of mortality associated with incorrect therapy in patients with CS-PA was 3.30 (1.01-10.82; p = 0.043). The mortality of patients with bacteremia caused by CR-PA was unexpectedly similar regardless of antimicrobial treatment adequacy. CONCLUSION: Appropriate treatment for CS-PA bacteremia initiated within the first 24 hours was associated with lower mortality, but this cannot be extrapolated for CR-PA.

Sex, drugs, bugs, and age: rational selection of empirical therapy for outpatient urinary tract infection in an era of extensive antimicrobial resistance

BACKGROUND: Optimal empirical therapy of urinary tract infection requires accurate knowledge of local susceptibility patterns, which may vary with organism and patient characteristics. METHODS: Among 9,798 consecutive, non-duplicate, community-source urine isolates from ambulatory patients > 13 years old, from clinical laboratory and an academic medical center in Curitiba, Brazil (May 1st to December 1st, 2009), susceptibility data for ampicillin, nitrofurantoin, trimethoprim-sulfamethoxazole, gentamicin, fluoroquinolones, and ceftriaxone/cefotaxime were compared with organism and patient gender and age. RESULTS: The female-to-male ratio decreased with age, from 28.1 (among 20-29 year-olds) to 3.3 (among > 80 year-olds). Overall, susceptibility prevalence varied widely by drug class, from unacceptably low levels (53.5% and 61.1%: ampicillin and trimethoprimsulfamethoxazole) to acceptable but suboptimal levels (81.2% to 91.7%: fluoroquinolones, ceftriaxone, nitrofurantoin, and gentamicin). E. coli isolates exhibited higher susceptibility rates than other isolates, from 3-4% higher (fluoroquinolones, gentamicin) to > 30% (nitrofurantoin, ceftriaxone). Males exhibited lower susceptibility rates than females. Within each gender, susceptibility declined with increasing age. For females, only nitrofurantoin and gentamicin were suitable for empirical therapy (> 80% susceptibility) across all age cohorts; fluoroquinolones were suitable only through age 60, and ceftriaxone only through age 80. For males, only gentamicin yielded > 80% susceptibility in any age cohort. CONCLUSION: Few suitable empirical treatment options for community-source urinary tract infection were identified for women aged over 60 years or males of any age. Empirical therapy recommendations must consider the patient's demographic characteristics. Site-specific, age and gender-stratified susceptibility surveillance involving all uropathogens is needed.

Uncommon vancomycin-induced side effects

Vancomycin has been used with increased frequency during the past 15 years and the most common toxicity with this drug is the red man syndrome . Other adverse effects include neutropenia, fever, phlebitis, nephrotoxicity, ototoxicity, thrombocytopenia, interstitial nephritis, lacrimation, linear IgA bullous dermatosis, necrotizing cutaneous vasculitis and toxic epidermal necrolysis. Only two cases of vancomycin-induced Stevens-Johnson syndrome and one case of pancytopenia have been reported in the medical literature. The treatment for both situations is based on cessation of the vancomycin therapy; in cases of Stevens-Johnson syndrome, antihistamine and/or steroid agents can be used. This article reports a case of pancytopenia and a case of erythema major associated with neutropenia.

Aspectos relevantes da interface entre diabetes mellitus e infecção / Relevant aspect in the interface between diabetes mellitus and infection

O diabetes mellitus (DM) é uma doença de alta prevalência nas sociedades modernas, na maioria das vezes com tratamento inadequado ou ausente. Apesar de geralmente considerado como fator de risco independente para ocorrência e gravidade de infecções em geral, o DM não apresenta evidência clínica forte de sua relação com infecção. Observa-se, porém, uma maior ocorrência de certas infecções em pacientes com DM, com curso menos favorável para algumas delas. Há também tipos de infecção quase exclusivos de pacientes com DM. Experimentalmente, observa-se depressão da atividade dos neutrófilos, menor eficiência da imunidade celular, alteração dos sistemas antìoxidantes e menor produção de interleucinas. Com relação às infecções comuns, as que envolvem o trato respiratório não têm comprovadamente maior gravidade em pacientes com DM, exceção feita ao pneumococo - por isso a recomendação para sua vacinação contra S. pneumoniae e influenza. Quanto ao trato urinário, há maior ocorrência de bacteriúria assintomática em mulheres com DM, com maiores índices de pielonefrite, necrose papilar, abscesso perinéfrico, pìelonefrite xantogranulomatosa, e cistite e pielonefrite gangrenosas. Periodontite e infecções de partes moles são também mais comuns no DM. Cada tipo de infecção é associado a germes típicos, e seu conhecimento é fundamental para um tratamento inicial adequado. As infecções quase exclusivas de pacientes com DM incluem otite externa maligna, mucormicose rinocerebral, colecistìte gangrenosa e o somatório de alterações que caracterizam o pé diabético. O conhecimento destas infecções assume maior importância por requererem freqüentemente uma abordagem multidisciplinar, envolvendo endocrinologistas, infectologistas, cirurgiões vasculares e nefrologistas, dentre outros.

Municipio y saneamiento basico la gestion de residuos solidos y sus aplicaciones tecnicas y socioeconomicas: el caso de la ciudad de Cochabamba (19992-95) / sss

Las caracteristicas ambientales de Cochabamba representan un escenario natural y social bastante complejo para entender los procesos en la gestion de residuos solidos. El clima seco disminuye el riesgo de descomposicion de la basura, esto tiene que ver mucho con la contaminacion atmosferica por su incidencia en el fenomeno de la inversion termica. Las estrategias propuestas en el trabajo, pretende rescatar y apoyar experiencias locales que anivel de informal ya estan bastente difundidas, economicamente parecen alternativas interesantes y socialmente aceptables. Sobre esta base se articula con las nuevas tendencias que a nivel global promueven un manejo y gestion sustentable de residuos solidos
