Análise das solicitações de medicamentos não padronizados de um hospital universitário terciário / Analysis of requests for non-standard medicines from a tertiary university hospital

Introdução: O uso extensivo de medicamentos não padronizados causa aumento de custos em saúde, além de potencial redução de segurança e uso racional de medicamentos. A Comissão de Farmácia e Terapêutica orienta a prescrição de medicamentos, por meio da avaliação e seleção de medicamentos a serem incluídos no formulário de medicamentos padronizados, com base nas melhores evidências científicas disponíveis e no perfil dos pacientes locais, promovendo o uso racional de medicamentos. O objetivo deste trabalho foi analisar as solicitações de fornecimento de medicamentos não padronizados na instituição. Métodos: Trata-se de um estudo observacional e descritivo onde foram analisadas as solicitações de medicamentos não padronizados realizadas entre fevereiro de 2016 e dezembro de 2021, identificando os medicamentos envolvidos e seus respectivos custos. Resultados: Foram realizadas 203 solicitações no período, sendo 174 incluídas no estudo. Os medicamentos que tiveram mais solicitações foram o rituximabe (41), a imunoglobulina humana (31), o sucralfato (23), a nitazoxanida (12) e o eltrombopague (7). As solicitações com maior custo foram as de imunoglobulina humana (US$ 799,702.38), rituximabe (US$ 717,320.26), eltrombopague (US$ 281,062.50), ruxolitinibe (US$ 167,867.46) e bortezomibe (US$ 149,033.52). As principais clínicas que solicitaram medicamentos não padronizado foram a neurologia (47), a hematologia (30), as moléstias infecciosas e parasitárias (17), e a anestesiologia (12). As solicitações de maior custo foram realizadas pela neurologia (US$ 145,519.08), hematologia (US$ 120,980.25), transplante de medula óssea (US$ 51,635.11) e dermatologia (US$ 44,813.40). Conclusão: O estudo demonstrou que há um fluxo estruturado de solicitação de medicamentos não padronizados na instituição, sendo uma importante ferramenta de gerenciamento dessas solicitações, evitando a aquisição desnecessária de itens que não compõem o elenco terapêutico do hospital.

Introduction: Widespread use of non-formulary drugs (NFD) increases cost and may reduce safety and rational use of medicines. The Pharmacy and Therapeutics Committee provides guidance on drug prescription by evaluating and selecting medications to be included in a hospital's formulary based on best scientific evidence available and local patients' profile, promoting rational use of medicines. The objective of this study was to assess non-formulary drugs prescriptions at a tertiary hospital. Methods: This was a retrospective study. NFD prescribed and its associated costs were assessed through NFD request forms received from February 2016 to December 2021. Results: A total of 203 NFD request forms were received, from which 174 were included in this study. The most frequently prescribed NFD included rituximab (n = 41), immunoglobulin (31), sucralfate (23), nitazoxanide (12), and eltrombopag (7), with the highest costs being with immunoglobulin (US$ 799,702.38), rituximab (US$ 717,320.26), eltrombopag (US$ 281,062.50), ruxolitinib (US$ 167,867.46), and bortezomib (US$ 149,033.52). The most frequent requesting specialties were neurology (n = 47), hematology (30), infectious disease (17) and anesthesiology (12), and highest costs requests were from neurology (US$ 145,519.08), hematology (US$ 120,980.25), bone marrow transplant unit (US$ 51,635.11), and dermatology (US$ 44,813.40). Conclusion: This study showed that a structured request flow for NFD prescription is a critical procedure in order to better manage drug prescription within the hospital, promoting rational use of medicines and preventing unnecessary spending with drugs for which the clinical indication may be covered by a drug already in the hospital's formulary.

Avaliação da economia gerada por meio das intervenções farmacêuticas realizadas em um hospital universitário terciário de grande porte / Evaluation of cost savings generated through pharmaceutical inverventions performed in a large tertiary university hospital

Introdução: A farmácia clínica tem como objetivo garantir uma farmacoterapia adequada ao paciente. A avaliação de prescrição é uma das principais atividades do farmacêutico clínico, o que pode resultar em intervenções e economia para a instituição, além de promover o uso racional e seguro de medicamentos. O objetivo deste estudo foi avaliar a economia gerada por meio das intervenções realizadas pelos farmacêuticos clínicos durante o processo de avaliação farmacêutica de prescrição. Métodos: Estudo transversal, observacional e analítico, onde foi analisada a economia gerada através das intervenções realizadas pelos farmacêuticos no período entre janeiro e julho de 2017. Resultados: Foram realizadas 3.033 intervenções no período do estudo e 943 foram incluídas. O valor da economia gerada foi de R$ 72.648,39 (US$ 23.134,95), sendo as intervenções mais frequentes relacionadas à adequação de apresentação (847) e forma farmacêutica (44). Dentre os medicamentos cujas intervenções farmacêuticas resultaram em maior economia, estão a anfotericina B lipossomal (R$ 18.919,75), a daptomicina (R$ 8.575,00), o valganciclovir (R$ 7.452,00) e a anidulafungina (R$ 7.422,35). Algumas intervenções não resultaram em economia direta do tratamento medicamentoso, como ocorreu com a risperidona comprimido (− R$ 264,04) e o sulfametoxazol+trimetoprima comprimido (− R$ 208,62), que foram substituídos por solução oral para administração por sondas. Conclusão: O estudo demonstrou que a atuação do farmacêutico clínico resultou na efetivação de intervenções relacionadas à adequação de dose, correção de diluição, alteração de apresentação, substituição de forma farmacêutica, adequação de tempo de tratamento e a adesão aos protocolos institucionais. Essas intervenções refletiram diretamente na redução de custo dos tratamentos, otimizando recursos e gerando economia ao serviço de saúde. (AU)

Introduction: Clinical pharmacy aims to ensure appropriate pharmacotherapy for patients. Prescription evaluation is one of the main activities of the clinical pharmacist and can result in interventions and cost savings for the institution, in addition to promoting the rational and safe use of medications. The objective of this study was to evaluate cost savings generated through interventions performed by clinical pharmacists during the process of prescription evaluation. Methods: This cross-sectional, observational, analytical study analyzed cost savings generated through interventions performed by pharmacists from January to July 2017. Results: A total of 3,033 interventions were performed during the study period, of which 943 were included. Cost savings amounted to R$ 72,648.39 (US$ 23,134.95), and the most frequent interventions were related to the adequacy of presentation (847) and dosage form (44). The medications whose pharmaceutical interventions resulted in the greatest cost savings are liposomal amphotericin B (R$ 18,919.75), daptomycin (R$ 8,575.00), valganciclovir (R$ 7,452.00), and anidulafungin (R$ 7,422.35). Some interventions did not result in direct cost savings, such as treatment with risperidone tablet (− R$ 264.04) and trimethoprim-sulfamethoxazole tablet (− R$ 208.62), which were replaced by oral solution for tube administration. Conclusion: The study demonstrated that the performance of clinical pharmacists resulted in the implementation of interventions related to dose adjustment, dilution correction, change of presentation, replacement of dosage form, adjustment of treatment duration, and adherence to institutional protocols. These interventions directly resulted in the reduction of treatment costs, optimizing resources and generating cost savings for the health system. (AU)

Assessment of the adherence to and costs of the prophylaxis protocol for venous thromboembolism

OBJECTIVES: Evaluate adherence to the therapeutic prophylaxis protocol for venous thromboembolism (VTE) as well as the costs of this practice. METHODS: A descriptive and cross-sectional study was conducted at a State General Hospital in Brazil through reports of drug dispensions, prescriptions and risk stratification of patients. Adherence to the VTE prophylaxis protocol was monitored. The tests for VTE diagnosis measured the adherence to therapeutic prophylaxis treatment, and the purchase prices of the drugs went into the calculation of drug therapy costs. The level of adherence to prescriptions for VTE prophylaxis in the hospital was classified as "adherence", "non-adherence" and "justified non-adherence" when compared with the protocol. RESULTS: Protocol adherence was observed for 50 (30.9%) patients, and non-adherence was observed for 63 (38.9%) patients, generating an additional cost of $180.40/month. Justified non-adherence in 49 (30.2%) patients generated $514.71/month in savings due to a reduction in the number of daily administrations of unfractionated heparin while still providing an effective method for preventing VTE. Twenty-six patients stratified as having medium to high risk of VTE who did not receive prophylaxis were identified, generating $154.41 in savings. However, these data should be evaluated with caution since the risks and outcomes associated with not preventing VTE outweigh the economy achieved from not prescribing a drug when a patient needs it. The only case of VTE identified during the study period was related to justified non-adherence to the protocol. CONCLUSION: The protocol is based on scientific evidence that describes an effective therapy to prevent VTE. However, the protocol should be updated because the justifications for non-adherence are based on scientific evidence, and this justified non-adherence generates savings and yields effective disease prevention.

Perfil de gastos com o tratamento da Artrite Reumatoide para pacientes do Sistema Único de Saúde em Minas Gerais, Brasil, de 2008 a 2013 / Profile of spending on the treatment of rheumatoid arthritis for patients of the Unified Health System in the state of Minas Gerais - 2008-2013

Resumo A artrite reumatoide (AR) é uma doença crônica que afeta cerca de 1% da população adulta. No estudo de coorte histórica de pacientes de Minas Gerais, registrados no Sistema de Informações Ambulatoriais (SIA), em 2008-2013, foram identificados 11.573 indivíduos. A perspectiva foi a do financiador público e os valores observados como gastos do Sistema Único de Saúde (SUS) foram ajustados pelo Índice Nacional de Preços ao Consumidor Amplo (IPCA), de dezembro de 2015. O Etanercept foi o tratamento mais caro. A análise múltipla mostrou uma relação negativa entre o aumento das despesas e idade, sexo feminino e diagnóstico de entrada na coorte, e relação positiva para as variáveis Índice de Desenvolvimento Humano Municipal (IDH-M) e o uso de medicamentos bloqueadores do fator de necrose tumoral (ANTI-TNF). Este estudo identificou os fatores que têm impacto sobre o gasto com o tratamento medicamentoso da AR. Também apontou que métodos que permitem extrair dados demográficos e de gastos de sistemas de informação administrativos podem ser ferramentas importantes na construção de estudos econômicos capazes de subsidiar as avaliações econômicas de saúde, especialmente do ponto de vista da gestão.

Abstract Rheumatoid arthritis (RA) is a chronic condition that affects about 1% of the adult population. In a historical cohort of Minas Gerais State, 11,573 RA patients registered in the Outpatient Information System (SIA) between 2008 and 2013 were identified. For this study we adopted the public funding body's perspective and the values were adjusted by the national inflation index (IPCA) of December 2015. Etanercept was the most expensive treatment. The mean cohort age was 52 years old and most of the patients were women. Multiple regression analysis indicated a negative association between higher expenditure and age, female sex, and diagnosis at entry in the cohort and positive association between high expenditure and the Human Development Index (HDI) of the municipality and use of tumor necrosis factor agents. This study identified the factors that have an impact on RA drug treatment expenditure. Also, we showed that methods that enable extracting demographic and expenditure data of administrative information systems may represent important tools in the construction of economic studies to subsidize economic health evaluations, especially from the standpoint of the managers.

Cost-consequence analysis of Pharmaceutical Care program for systemic arterial hypertension in the public health system in Brazil

ABSTRACT In Brazil, 80% of hypertensive patients have no blood pressure controlled, this fact has caused severe financial consequences for the public health system (PHS) and the Pharmaceutical Care (PC) has emerged as an effective alternative. The aim of this study was to analyze the costs and outcomes of systemic arterial hypertension (SAH) for conventional assistance compared to assistance with PC in the PHS. This is a pharmacoeconomic study with cost-consequence analysis nested to clinical trial. Hypertensives patients were followed-up from 2006 to 2012. During 2009 they were assisted by the PC program in Ribeirão Preto-SP, Brazil. Clinical indicators, systolic and diastolic blood pressure (SBP and DBP), triglycerides, total cholesterol (TC) and its fractions and healthcare indicators, consumption of antihypertensive medication and consultations were analyzed. Costs were listed as direct medical and direct non-medical. The average cost of conventional care for 104 patients followed-up was US$ 198.97, in the PC period and after discharge was US$ 407.91 and US$ 214.96 patient/year. After discharge of patients from PC there was reduction of SBP, DBP, TC and cardiovascular risk, 9.4 mmHg, 4.6 mmHg, 12.0 mg/dL, and 23% [p<0.005], respectively. The PC program optimized clinical and healthcare indicators and impacted in the SAH costs for the PHS.

Uso y gasto en medicamentos antihipertensivos en el subsector público de salud de la provincia del Neuquén en 2012-2014 / Use of and spending on antihypertensive drugs in the public health subsector of Neuquén province in 2012-2014

INTRODUCCIÓN: la hipertensión arterial es un factorde riesgo con alto impacto en la morbi-mortalidad cardiovascular. Laprescripción de antihipertensivos no siempre sigue las recomendacionesvigentes, lo que representa un uso ineficiente de los recursos.OBJETIVOS: Evaluar el uso de medicamentos antihipertensivos, costosasociados y grado de adecuación a las recomendaciones provinciales.MÉTODOS: Se analizaron las compras de medicamentosantihipertensivos de la Subsecretaría de Salud provincial y entregasdel Plan Remediar para 2012-2014. Los consumos se expresaron endosis diaria definida (DDD)/1000 habitantes. RESULTADOS: El gastoen medicamentos antihipertensivos representó un 1,14% del total delgasto anual en medicamentos. Las DDD/1000 habitantes provistasen los años sucesivos fueron 75,5; 86,7 y 73,8. El sistema público deSalud provincial financió dos terceras partes, y el Plan Remediar elresto. El costo de adquisición por compra directa fue, en promedio,un 79% mayor que el de licitación pública. Más de dos tercios de lasDDD correspondieron a enalapril e hidroclorotiazida. CONCLUSIONES:La erogación en antihipertensivos representa una mínima partedel gasto provincial en medicamentos. El patrón de prescripción nose adecua completamente a la Guía de Práctica Clínica provincial, conuna relación hidroclorotiacida-enalapril inversa a la recomendada.Pese a esto, el 80% de las DDD dispensadas corresponden a estosdos medicamentos, lo que se considera una forma de uso racional.

INTRODUCTION: hypertension is a risk factor withhigh impact on cardiovascular morbidity and mortality. The prescriptionof antihypertensive drugs does not always follow currentrecommendations, which represents an inefficient use of resources.OBJECTIVES: To assess the use of antihypertensive medications,costs and adequacy to provincial recommendations. METHODS:Information on antihypertensive medications purchase was obtainedfrom provincial Health Undersecretariat, and deliveries ofPlan Remediar for 2012-2014. Drug use was expressed as defineddaily doses (DDD) per 1000 inhabitants. RESULTS: Spending onantihypertensive medications accounted for 1.14% of total annualdrug spending. The DDD/1000 inhabitants provided were 75.5 in2012, 86.7 in 2013 and 73.8 in 2014. The provincial public healthsystem funded two thirds, and Plan Remediar the remaining third.The average cost of direct purchase was 79% higher than with publicauction purchase. More than two thirds of DDD corresponded toenalapril (EN) and hydrochlorothiazide (HCT). CONCLUSIONS:Spending on antihypertensive drugs represents a minimum fractionof total provincial drug spending. The prescription pattern doesnot fully adhere to the clinical practice guidelines, with a HCT-ENrelationship that is inverse compared to the recommended one.In spite of this, 80% of the dispensed DDD correspond to thesetwo drugs, which is considered a rational use.

Há irracionalidades no consumo de inibidores de apetite no Brasil? Uma análise farmacoeconométrica de dados em painel / Are there irrationalities in the consumption of anti-obesity drugsin Brazil? A pharmaco-econometric analysis of panel datasets

Este estudo busca analisar os determinantes do consumo de inibidores de apetite (anfepramona, femproporex, mazindol e sibutramina) por meio da estimação de um modelo dinâmico de dados em painel para as capitais brasileiras e do Distrito Federal (DF) no período de 2009 a 2011. Os resultados revelam que o consumo de inibidores de apetite não acompanhou a distribuição geográfica dos indivíduos com excesso de peso e com obesidade nas unidades estudadas. Do consumo recorrente de inibidores, 79% são explicados pelo ocorrido no passado. Dentre as variáveis que explicam o consumo de inibidores, destacam-se os percentuais de adultos com obesidade e que dos que consomem frutas e hortaliças e a taxa de cobertura de planos de saúde. A análise farmacoeconométrica sugere que há problemas no uso racional dos inibidores de apetite nas capitais brasileiras e no DF, seja no que tange ao consumo desses medicamentos com outros fármacos - considerados ilegais pelo Conselho Federal de Medicina e pela Anvisa - e, também, na indicação terapêutica de uso desses produtos.

The scope of this study is to analyze the determinants of the use of appetite suppressants (amfepramone, femproporex, mazindol and sibutramine) through the estimation of a dynamic panel dataset model for the Brazilian state capitals and the Federal District (DF) in the period from 2009 to 2011. The results show that consumption of appetite suppressants did not follow the geographic distribution of overweight and obese individuals across the capitals and DF. There is a recurrent consumption of appetite inhibitors, in which 79% of the current consumption of these drugs is explained by past consumption. Among the variables that explain the use of inhibitors, the percentage of obese adults, the percentage of adults who habitually consume fruit and vegetables, and the coverage rate of health plans stand out. The pharmaco-econometric analysis suggests that there are problems in the rational use of appetite suppressants in the Brazilian state capitals and the Federal District with respect to both the combined consumption of these drugs with other medicines - deemed illegal by the Federal Council of Medicine and ANVISA - and in the therapeutic prescription of these products.

Impact of group purchasing in cooperative of hospital in Colombia, using a price index from 1999 to 2012 / Impacto del grupo de compra en la cooperativa de hospital en Colombia, con un índice de precios de 1999 a 2012

The application of price indices is useful to analyze the behavior of prices as an important component in patients´ access to essential medications over a period of time. The present work analyzed the variation in the prices of 303 medications sold by a cooperative of hospitals in central Colombia between 1999 and 2010 by applying inflation-adjusted price indices and Laspeyres-Paasche quantities by ABC groups and principal therapeuticals in the first and second ATC (anatomic, therapeutical, chemical) level, taking 1999 as the starting year. The medications of type A and B, as well as those belonging to the first four therapeutical groups in the first ATC level in cost and for seven groups in the second ATC level, registered a drop between 40 and 53% (P < 0.05) in the applied price indices. In addition, all the ABC and ATC groups showed increases between 9 and 12 times (P < 0.01) when applying the indices on units sold. The estimated net saving in 2010 at prices of 1999, went above $ 16.9 billion COP. This impact on prices has helped to expand the coverage in essential medications supplied to the public hospitals which are afterwards administered to the patients of this region of Colombia.

La aplicación de los índices de precios es útil para analizar el comportamiento de los precios como un componente importante en el acceso de los pacientes a los medicamentos esenciales en un determinado período de tiempo. El presente trabajo analiza la variación de los precios de 303 medicamentos comercializados por una cooperativa de hospitales en el centro de Colombia entre 1999 y 2010 mediante la aplicación de los índices de precios ajustados a la inflación, según las expresiones de Laspeyres y Paasche por grupos ABC y de principales agentes terapéuticos en el primer y segundo nivel ATC (anatómico, terapéutico, químico), tomando 1999 como año de partida. Los medicamentos de tipo A y B, así como los que pertenecen a los cuatro primeros grupos terapéuticos en el primer nivel de ATC en el costo, y considerando siete grupos en el segundo nivel de ATC, registraron una caída entre 40% y 53% (P < 0,05) en los índices de precios aplicados. Además, todos los grupos ABC y ATC mostraron aumentos entre 9 y 12 veces (P < 0,01) al aplicar los índices en las unidades vendidas. El ahorro neto estimado en 2010 a precios de 1999, pasó por encima de 16,9 mil millones de pesos colombianos. Este impacto en los precios ha contribuido a ampliar la cobertura en los medicamentos esenciales suministrados a los hospitales públicos, y que luego son administrados a los pacientes de esta región de Colombia.

Use of Drug-eluting Stents Versus Bare-metal Stents in Korea: A Cost-minimization Analysis Using Population Data / 예방의학회지

OBJECTIVES: The goal of this study was to perform an economic analysis of a primary stenting with drug-eluting stents (DES) compared with bare-metal stents (BMS) in patients with acute myocardial infarction (AMI) admitted through an emergency room (ER) visit in Korea using population-based data. METHODS: We employed a cost-minimization method using a decision analytic model with a two-year time period. Model probabilities and costs were obtained from a published systematic review and population-based data from which a retrospective database analysis of the national reimbursement database of Health Insurance Review and Assessment covering 2006 through 2010 was performed. Uncertainty was evaluated using one-way sensitivity analyses and probabilistic sensitivity analyses. RESULTS: Among 513 979 cases with AMI during 2007 and 2008, 24 742 cases underwent stenting procedures and 20 320 patients admitted through an ER visit with primary stenting were identified in the base model. The transition probabilities of DES-to-DES, DES-to-BMS, DES-to-coronary artery bypass graft, and DES-to-balloon were 59.7%, 0.6%, 4.3%, and 35.3%, respectively, among these patients. The average two-year costs of DES and BMS in 2011 Korean won were 11 065 528 won/person and 9 647 647 won/person, respectively. DES resulted in higher costs than BMS by 1 417 882 won/person. The model was highly sensitive to the probability and costs of having no revascularization. CONCLUSIONS: Primary stenting with BMS for AMI with an ER visit was shown to be a cost-saving procedure compared with DES in Korea. Caution is needed when applying this finding to patients with a higher level of severity in health status.

Evidências advindas do consumo de medicamentos moduladores do apetite no Brasil: um estudo farmacoeconométrico / Evidence for the use of appetite suppressant drugs in Brazil: a pharmacoeconometric study

OBJETIVO: Analisar o consumo de moduladores do apetite (CMA) no Brasil em 2009, condicionado às características dos usuários, do sistema de saúde e de outros medicamentos. MÉTODOS: Estudo farmacoeconométrico com dados em corte transversal para analisar as relações entre o CMA (mg/per capita) e as variáveis independentes selecionadas (gênero, raça/cor, faixa etária, escolaridade, renda, cobertura de planos de saúde e consumo de fluoxetina e clordiazepóxido), mediante análise de regressão linear múltipla. Este estudo utilizou-se dessas variáveis em nível de agregação por estados para 2009. As análises foram realizadas no software Gretl. RESULTADOS: Destacamos que São Paulo registrou o maior CMA, com 97,3 mg/per capita, seguido de Goiás, com 94,8 mg/per capita. O menor consumo foi verificado no Ceará (3,8 mg/per capita). Os maiores consumidores de fluoxetina foram o Rio Grande do Sul, com 58,0 mg/per capita, e Goiás, com 51,5 mg/per capita. O Ceará (2,3 mg/per capita) registrou o menor con-sumo. Para o clordiazepóxido, os maiores valores foram verificados em Minas Gerais (7,5 mg/per capita) e Rio de Janeiro (4,8 mg/per capita), enquanto que o Amazonas (0,08 mg/per capita) obteve o menor consumo. Da análise de regressão destacamos: 1) o CMA está relacionado com renda, escolaridade e consumo de fluoxetina; e 2) raça/cor, gênero, idade, cobertura de plano de saúde e consumo de clordiazepóxido, porém revelaram-se não relacionados com CMA. CONCLUSÃO: Essas evidências podem contribuir para o aprimoramento das ações de regulação, vigilância sanitária e de conduta ética, principalmente, no que tange o consumo "casado" de moduladores do apetite com fluoxetina, o qual é vedado pelo Conselho Federal de Medicina, e, também, pela Anvisa.

OBJECTIVE: Analyze the use of appetite suppressants in Brazil in 2009, according to the characteristics of users, healthcare system, and other drugs. METHODS: Pharmaconeconometric study of cross-sectional data to analyze the relationship between the use of appetite suppressants (mg/per capita) and the independent variables selected (gender, race/color, age, schooling, income, health insurance coverage, and use of fluoxetine and chlordiazepoxide) using multiple linear regression analysis. This study used these variables in level of aggregation by states for 2009. The analyses were performed using the Gretl software. RESULTS: We highlight that São Paulo showed the highest use of appetite suppressants with 97.3 mg/per capita, followed by Goiás with 94.8 mg/per capita. The lowest use of appetite suppressants was seen in Ceará (3.8 mg/per capita). The biggest fluoxetine users were in Rio Grande do Sul, with 58.0 mg/per capita, and in Goiás, with 51.5 mg/per capita. Ceará showed the lowest fluoxetine use (2.3 mg/per capita). For chlordiazepoxide, the highest values were seen in Minas Gerais (7.5 mg/per capita) and in Rio de Janeiro (4.8 mg/per capita), while Amazonas (0.08 mg/per capita) showed the lowest use. Based on regression analysis, we can highlight: 1) the use of appetite suppressants is related to income, education, and fluoxetine use; and 2) race/color, gender, age, health insurance coverage, and use of chlordiazepoxide showed no relation to the use of appetite suppressants. CONCLUSION: These evidences may contribute to the improvement of regulatory actions, sanitary surveillance, and ethical conduct, particularly with regard to the concomitant use of appetite suppressants and fluoxetine, which is prohibited by the Federal Council of Medicine (Conselho Federal de Medicina) and also by Anvisa (Agência Nacional de Vigilância Sanitária - National Health Surveillance Agency).

Pharmacoeconomics of antidepressants in moderate-to-severe depressive disorder in Colombia / Farmacoeconomía de antidepresivos en trastornos de depresión moderada e intensa en Colombia

OBJECTIVE: To compare three antidepressant drugs from different classes used in treating moderate-to-severe major depressive disorder (MDD) in Colombian adults. METHODS: Based on expert input, a decision-tree model was adapted for Colombia to analyze data over 6 months from the government-payer perspective. The cost-effectiveness of amitriptyline, fluoxetine, and venlafaxine was determined. The clinical outcome was remission of depression (a score <7 on the Hamilton Depression [HAM-D] scale or <12 on the Montgomery-Åsberg Depression Rating Scale [MADRS]) after 8 weeks of treatment. Clinical data were obtained from the literature and costs from standard Colombian price lists. One-way and multivariate sensitivity analyses tested model robustness. RESULTS: Costs per patient (in 2007 US$) for treatment were: venlafaxine, $1 618; fluoxetine, $1 207; and amitriptyline, $1 068. Overall remission rates were 73.1 percent, 64.1 percent, and 71.3 percent, respectively. Amitriptyline dominated fluoxetine (i.e., it had lower costs and higher outcomes). The incremental cost-effectiveness ratio (ICER) of venlafaxine over amitriptyline was US$ 31 595. The acquisition price of venlafaxine was the model's cost driver, comprising 53.4 percent of the total cost/patient treated, compared with 18.5 percent and 24.8 percent for fluoxetine and amitriptyline, respectively. For the others, hospitalization comprised the major cost (72.1 percent and 65.2 percent, respectively). Probabilistic (Monte Carlo) sensitivity analysis confirmed the original findings of the pharmacoeconomic model. CONCLUSIONS: Amitriptyline is cost-effective in comparison to fluoxetine and venlafaxine in Colombia. However, the cost of venlafaxine was estimated for the brand-name product, as generics were not currently available. These cost-effectiveness results can be substantially affected by the presence of generics or drug cost regulations.

OBJETIVO: Comparar tres medicamentos antidepresivos de diferentes clases empleados para tratar trastornos depresivos mayores moderados e intensos en adultos colombianos. MÉTODOS: A partir de los aportes de expertos se adaptó un modelo de árbol de decisión para Colombia a fin de analizar los datos de seis meses desde la perspectiva del gobierno como pagador de los servicios. Se determinó la relación costo-efectividad de la amitriptilina, la fluoxetina y la venlafaxina. El desenlace clínico fue la remisión de la depresión (una puntuación <7 en la escala de depresión de Hamilton o <12 en la escala de valoración de la depresión de Montgomery-Åsberg) después de 8 semanas de tratamiento. Los datos clínicos se obtuvieron de la literatura especializada y los costos, de las listas habituales de precios de Colombia. Se realizaron análisis de sensibilidad simples y multifactoriales para probar la robustez de los modelos. RESULTADOS: Los costos del tratamiento por paciente (en dólares estadounidenses de 2007) fueron: US$ 1 618 para la venlafaxina, US$ 1 207 para la fluoxetina y US$ 1 068 para la amitriptilina. Las tasas de remisión general fueron 73,1 por ciento, 64,1 por ciento y 71,3 por ciento, respectivamente. La amitriptilina tuvo un menor costo y una mayor remisión que la fluoxetina. La razón de rentabilidad incremental de la venlafaxina sobre la amitriptilina fue de US$ 31 595. El inductor de costos (cost driver) del modelo fue el valor de adquisición de la venlafaxina, que representó 53,4 por ciento del total del costo por paciente tratado, en comparación con la fluoxetina (18,5 por ciento) y la amitriptilina (24,8 por ciento). En los otros casos, la hospitalización representó el mayor costo (72,1 por ciento y 65,2 por ciento, respectivamente). El análisis de sensibilidad probabilístico (Monte Carlo) confirmó los resultados preliminares del modelo farmacoeconómico. CONCLUSIONES: En Colombia, la amitriptilina es más efectiva en función del...

Comparación de costo-efectividad entre dos técnicas anestésicas: anestesia con sevofluorane-remifentanil frente a isofluorane-remifentanil / Cost-Effective Comparison Between Two Anesthesia Techniques: Sevofluorane-Remifentanyl vs Isofluorane-Remifentanyl

Nos encontramos en la era de la optimización de costos, por lo que es necesario realizar estudios farmacoeconómicos para identificar la costo- efectividad de los anestésicos actuales. Metodología: este estudio prospectivo, cegado al paciente, comparó los costos directos, los tiempos de recuperación y satisfacción de 45 pacientes que se asignaron aleatoriamente a dos grupos de anestesia balanceada (grupo sevofluoraneremifentanil n = 24 o grupo isofluoraneremifentanil n = 21) que iban a ser sometidos a cirugías de otorrinolaringología. Resultados: los tiempos de recuperación temprana (apertura ocular, respuesta a comandos, extubación, orientación y salida de sala) fueron menores en el grupo ISO y tuvieron diferencia estadísticamente significativa. Se encontraron datos variables en los costos de adquisición de los halogenados gastados, que fueron menores para el isofluorane, lo cual hacía también menos costosos los insumos anestésicos durante las cirugías; sin embargo, los costos en la sala de cirugía, en recuperación y sala de ambulatorios y los costos totales no mostraron diferencias significativas. La satisfacción fue similar entre los dos grupos. Conclusiones: una técnica basada en sevofluorane-remifentanil no es más costo-efectiva que utilizar isofluorane-remifentanil para pacientes ambulatorios sometidos a cirugías de otorrinolaringología.

We are in the of costs optimization era, reason why it is necessary to make pharmaceutical economics studies to identify the costeffectiveness of today's anesthetics. Methods: this prospective study, blinded to the patient, compared the direct costs, recovery times and satisfaction of 45 patients randomly assigned to two balanced anesthesia groups (sevofluoraneremifentanil group n = 24 or isofluoraneremifentanil group n = 21) submitted to otorhinolaringology surgical procedures. Results: the times of early recovery (ocular opening, answer to commandos, extubación, orientation and room leave) were smaller in ISO group and had statistically significant difference. Variable data was found in acquisition costs of halogenados gastados, lesser for isofluorane, which also made the anesthetic supplies less expensive during surgical procedures; nevertheless, costs in the delivery room, in recovery and ambulatory room, and the total costs did not show significant differences. Satisfaction was similar between both groups. Conclusions: a sevofluorane-remifentanil based technique is not more cost-effective than to use isofluoraneremifentanil for ambulartory patients submitted to otorhinolaringology surgical procedures.
