Antimicrobial stewardship for surgical antibiotic prophylaxis and surgical site infections: a systematic review.

Background Surgical site infections account for 14-17% of all healthcare-associated infections. Antimicrobial stewardship (AMS) are complementary strategies developed to optimize the use of antimicrobials. Aim to evaluate the effectiveness of AMS in promoting adherence to surgical antibiotic prophylaxis protocols in hospitalized patients, reducing surgical site infection rate and cost-benefit ratio. Method This systematic review of randomized clinical trials, non-randomized clinical trials and before and after studies was performed using Pubmed, Cochrane, Web of Science, Scopus, Embase, Google Scholar and ClinicalTrials.gov, in addition to reference lists of included studies. The risk of bias of studies was measured by the ROBINS-I checklist and the quality of the evidence synthesis by GRADE. Results Fourteen before and after design studies were included. In 85.7% of the studies, AMS was effective in increasing adherence to surgical antibiotic prophylaxis protocols and in 28.5%, there was reduction in surgical site infection rate. Three studies evaluated cost-benefit ratio and found a favorable impact. Eight (57%) studies were at risk of moderate bias and six had severe bias. The evaluation of the synthesis of evidence showed quality ranging from low to very low. Conclusion AMS, such as audit, feedback, education, implementation of a protocol, and a computer-assisted decision support methodology, appear to be effective in promoting adherence to surgical antibiotic prophylaxis protocols, reducing surgical site infection rate with a positive economic impact. However, more studies, particularly randomized clinical trials, are needed to improve the level of evidence of available information on AMS in order to favor decision-making.

Psychoactive drugs in the Brazilian public health system: Use profile and associated factors

Abstract The purpose of this study is to estimate the prevalence of and characterize the use of psychoactive drugs among drug users in a Brazilian municipality, relating the findings to factors associated with the consumption of these substances. Through a cross-sectional design, 1,355 drug users from the public health systems community pharmacies were interviewed. Sociodemographic and health-related data were collected, as well as any other prescribed drugs. The prevalence of psychoactive drug use within the last month was 31.0%, with antidepressants and benzodiazepines being the most prescribed (53.5% and 24.6% respectively). Most psychoactive drug users were female (81.9%), lived with a partner (52.6%), had private health insurance (69.2%) and a monthly per-capita income up to one minimum wage (54.0%). The adjusted Odds Ratio (OR) confirmed the following factors to be positively associated with the use of psychoactive drugs: female gender (OR=2.06; 95% CI 1.44; 2.95), age ≥60 years old (OR=1.77; 95% CI 1.26; 2.48), follow-up with a psychologist (OR=4.12; 95% CI 1.84; 5.25), absence of regular physical activity (OR=1.59; 95% CI 1.13; 2.23), and smokers (OR=1.94; 95% CI 1.26; 2.97). Approximately one out of three individuals used at least one psychoactive drug. Health managers should focus the planning and actions aimed at their rational use for these groups, leading to increased overall treatment success

Antibiotic use in Brazilian hospitals in the 21st century: a systematic review.

INTRODUCTION: This systematic review aimed to assess antibiotic use in Brazilian hospitals in the 21st century, as well as to understand the different drug utilization metrics adopted to assess the consumption of these drugs. METHODS: We systematically reviewed five databases (MEDLINE [Medical Literature Analysis and Retrieval System Online], CENTRAL [The Cochrane Central Register of Controlled Trials], EMBASE® [Excerpta Medica Database], Scopus [Elsevier's abstract and citation database], and LILACS [Literatura Latino-Americana e do Caribe em Ciências da Saúde]) for observational or experimental studies that assessed antibiotic utilization in Brazilian hospitals. The main outcomes were the drug utilization metrics and the consumption of antibiotics. RESULTS: We included 23 studies, of which 43.5% were carried out in adult and pediatric care units, 39.1% in adult units, and 17.4% in pediatric units. Regarding the complexity of healthcare, 26.1% of the studies were performed in intensive care units. Two drug utilization metrics were used in these studies: the defined daily dose (DDD) and the percentage of antibiotic prescriptions. The most commonly used antibiotic classes were third-generation cephalosporins, carbapenems, fluoroquinolones, and combinations of penicillins when the DDD was the adopted drug utilization metric. CONCLUSIONS: Although few studies have been conducted, existing data indicate a high use of broad-spectrum antibiotics. We found that the lack of standardized antibiotic utilization metrics impaired the mapping of drug consumption at the national level.

Surgical antibiotic prophylaxis: is the clinical practice based on evidence?

OBJECTIVE: To assess the surgical antibiotic prophylaxis. METHODS: This was a descriptive study performed at a public tertiary care university hospital gathering prescription, sociodemographic and hospitalization data of inpatients admitted in 2014 who used antimicrobial drugs. This data were obtained from the hospital electronic database. The antimicrobial data were classified according to the anatomical, therapeutic chemical/defined daily dose per 1,000 inpatients. An exploratory analysis was performed using principal component analysis. RESULTS: A total of 5,182 inpatients were prescribed surgical antibiotic prophylaxis. Of the total antimicrobial use, 11.7% were for surgical antibiotic prophylaxis. The orthopedic, thoracic and cardiovascular postoperative units, and postoperative intensive care unit comprised more than half of the total surgical antibiotic prophylaxis use (56.3%). The duration of antimicrobial use of these units were 2.2, 2.0, and 1.4 days, respectively. Third-generation cephalosporins and fluoroquinolones had the longest use among antimicrobial classes. CONCLUSION: Surgical antibiotic prophylaxis was inadequate in the orthopedic, postoperative intensive care, thoracic and cardiovascular postoperative, gynecology and obstetrics, and otolaryngology units. Therefore, the development and implementation of additional strategies to promote surgical antibiotic stewardship at hospitals are essential.

Use of drugs for gastrointestinal disorders: evidence from National Survey on Access, Use and Promotion of Rational Use of Medicines.

Objective To estimate the prevalence of use of drugs to treat gastrointestinal disorders, according to demographic, socioeconomic, and health characteristics of the Brazilian population. Methods This is a population-based survey that interviewed individuals residing in cities of the five regions in Brazil. The study sample was composed of 32,348 individuals aged 20 or more years. The profile of use of drugs for gastrointestinal disorders was evaluated considering the variables sex, age, healthcare plan, region, and number of chronic diseases. We also analyzed the frequency of individuals who declared using other drugs, besides those already employed for treatment of gastrointestinal disorders. Additionally, the estimated frequencies of the drug classes used were determined. Results The prevalence of use of drugs for gastrointestinal disorders in Brazil was 6.9% (95% confidence interval - 6.4-7.6), higher in females, among persons aged over 60 years, in those who had a private healthcare insurance, and presented with two or more chronic diseases. It was noted that 42.9% of the aged who used drugs for gastrointestinal disorders were also on polypharmacy. As to the classes of drugs, 82% corresponded to drugs for the food tract and metabolism, particularly proton pumps inhibitors. Conclusion The use of drugs for treatment of gastrointestinal disorders was significant among women and elderly. In this age group, consumption may be linked to gastric protection due to polypharmacy. This study is an unprecedented opportunity to observe the self-reported consumption profile of these drugs in Brazil and, therefore, could subsidize strategies to promote their rational use.

Use of statins for the secondary prevention of stroke: are we respecting the scientific evidences?

BACKGROUND: Stroke accounts for approximately as 5.0% of disability-adjusted years of life and 10.0% of all deaths worldwide. Secondary stroke prevention in surviving individuals, which includes the use of statins, reduces atherothrombotic stroke recurrence, complications and mortality. The present study aimed to characterize the Brazilian population with stroke history and estimate the prevalence of statin use as secondary prevention. METHODS: This is a population-based cross-sectional study conducted in Brazilian urban areas. A total of 41.433 individuals were interviewed, representing 171 million of Brazilians, based on post-stratification weights. We included only participants aged 20 years or older who answered "yes" to the following question: "Did any doctor ever tell you that you had a stroke?" The main outcome was the prevalence of statin use among individuals who answered affirmatively. To identify the factors associated with stroke occurrence, the participants were categorized according to clinical and sociodemographic characteristics. RESULTS: Only 24.2% (95% CI 19.9 - 29.1) of those who reported history of stroke regardless of other conditions also reported statin use. However, the results indicated that 52.9% (95% CI 43.6 - 62.0) of individuals who reported a previous diagnosis of dyslipidemia stated the use of statins. Regarding patients who reported stroke and did not report dyslipidemia history, only 9.1% (95% CI 5.9 - 13.8) referred to use statins. CONCLUSION: This study showed a low prevalence of statin use by individuals with a history of stroke in Brazil. Actions involving the organization of services and training of professionals may positively impact the rates of stroke recurrence.

RESUMO Objetivo: Avaliar a utilização de antibioticoprofilaxia cirúrgica. Métodos: Foi realizado um estudo descritivo em um hospital universitário de cuidado terciário por meio de coleta de dados de prescrição, sociodemográficos e de hospitalização sobre todos os pacientes internados em 2014 que utilizaram pelo menos um medicamento antimicrobiano. Esses dados foram coletados da base de dados eletrônica do hospital. O consumo de antimicrobianos foi analisado de acordo com a classificação anatômica terapêutica e química/dose diária definida por mil pacientes-dia. Realizou-se uma análise exploratória por meio da análise de componentes principais. Resultados: Um total de 5.182 pacientes internados receberam prescrição de antibioticoprofilaxia cirúrgica, que corresponde a 11,7% do total de antibióticos utilizados no hospital. As unidades de ortopedia, pós-operatória de cirurgia torácica e cardiovascular e terapia intensiva pós-operatória foram responsáveis pela utilização de mais da metade (56,3%) da antibioticoprofilaxia cirúrgica. A duração de uso desses antimicrobianos nessas unidades foi 2,2, 2,0 e 2,4 dias, respectivamente. Cefalosporinas de terceira geração e fluoroquinolonas foram as classes de antimicrobianos com tempo de utilização mais longo. Conclusão: A utilização de antibioticoprofilaxia cirúrgica foi inadequada nas unidades de ortopedia, pós-operatória de cirurgia torácica e cardiovascular, terapia intensiva pós-operatória, ginecologia e obstetrícia e otorrinolarigonlogia. Portanto, são importantes o desenvolvimento e a implantação de estratégias que promovam o uso racional de antibioticoprofilaxia cirúrgica nos hospitais.

RESUMO Objetivo Estimar a prevalência de utilização de medicamentos para o tratamento de distúrbios gastrintestinais, segundo características demográficas, socioeconômicas e de saúde da população brasileira. Métodos Trata-se de inquérito de base populacional, que entrevistou indivíduos residentes em municípios das cinco regiões do Brasil. A amostra deste estudo foi composta por 32.348 indivíduos de 20 anos ou mais de idade. Foi avaliado o perfil de utilização de medicamentos para distúrbios gastrintestinais entre as variáveis sexo, idade, plano de saúde, região e número de doenças crônicas. Analisou-se a frequência de indivíduos que declararam utilizar outros medicamentos, além daqueles já utilizados para tratamento de distúrbios gastrintestinais. Além disso, foram estimadas as frequências das classes medicamentosas utilizadas. Resultados A prevalência de utilização de medicamentos para distúrbios gastrintestinais no Brasil foi de 6,9% (intervalo de confiança de 95% − 6,4-7,6), sendo maior no sexo feminino, entre pessoas acima de 60 anos de idade, naqueles que possuíam plano privado de saúde e tinham duas ou mais doenças crônicas. Observou-se que 42,9% dos idosos que utilizaram medicamentos para distúrbios gastrintestinais também eram polimedicados. Em relação às classes medicamentosas, 82% correspondiam a medicamentos para o trato alimentar e metabolismo, destacando os inibidores da bomba de prótons. Conclusão A utilização de medicamentos para tratamento de distúrbios gastrintestinais foi significativa entre mulheres e idosos. Nesta faixa etária, o consumo pode estar vinculado à proteção gástrica causada por polimedicação. Este estudo representa oportunidade inédita para observar o perfil de consumo autorreferido desses medicamentos no Brasil e pode, portanto, subsidiar estratégias para promoção de seu uso racional.

Avaliação da efetividade do acompanhamento farmacoterapêutico no controle do diabetes mellitus tipo 2 em longo prazo / Evaluation of the effectiveness of pharmacotherapy follow-up in long-term control of diabetes mellitus type 2

Introdução: O número de farmacêuticos que atuam em unidades básicas de saúde é reduzido, dificultando a execução do acompanhamento farmacoterapêutico (AFT) para um elevado número de pacientes. Portanto, deve-se estabelecer um período de execução do AFT, para que muitos pacientes sejam contemplados, contudo são escassos os estudos que avaliam a continuidade do controle da doença após a alta do serviço. Dessa forma, este estudo propôs avaliar o desfecho clínico de pacientes diagnosticados com Diabetes mellitus tipo 2 (DM2) após a alta de um serviço de AFT. Métodos: Estudo de coorte retrospectiva após estudo de intervenção de um acompanhamento farmacoterapêutico, que avaliou 64 pacientes divididos em dois grupos: estudo (participaram de um programa de AFT) e controle (não participaram do programa de AFT). Foram coletados dados clínicos e laboratoriais destes pacientes ao final do programa de AFT (baseline - março/2006 a fevereiro/2007), e nos quatro anos após o término do programa de AFT (março/2007 a agosto/2011). Resultados: Dentre os 64 pacientes, 56 foram incluídos. Nos quatro anos posteriores ao serviço observou-se nove óbitos, sendo seis do grupo controle e três do grupo de estudo (p=0,151). O grupo de estudo manteve os valores de hemoglobina glicada após AFT (HbA1c) (8,5% vs 8,0%, p = 0,082), enquanto que o grupo controle reduziu os valores de hemoglobina glicada (HbA1c) (9,1% vs 8,1%; p = 0,004). O controle da glicemia de jejum (GJ) do grupo de estudo foi mantido após quatro anos (149,5 mg/dL vs 148,8 mg/dL, p = 0,884), bem como o grupo controle (170,7 mg/dL vs 170,6 mg/dL, p = 0,993), no entanto ao comparar os dois grupos após AFT, o grupo de estudo apresenta valor significativamente menor que o grupo controle (p = 0,047). Conclusão: Apesar das diferenças obtidas entre os grupos com o AFT não permanecerem após quatro anos, os resultados clínicos e laboratoriais não apresentaram piora significativa nesse período. (AU)

Introduction: The number of pharmacists working at primary health care units is small, which means that pharmacotherapy follow-up (PFU) cannot be offered to a high number of patients. An established period of PFU could then lead to more patients being treated. However, studies assessing management of chronic diseases after discharge from this service are scarce. Thus, this study evaluated clinical outcomes of patients diagnosed with diabetes mellitus type 2 (DM2) after PFU discharge. Methods: This retrospective cohort study was conducted after a PFU intervention study, which evaluated 64 patients divided into two groups: study (who participated in a PFU program) and control (who did not participate in a PFU program). Laboratory and clinical data were collected from these patients at the end of the program (baseline ­ March 2006 to February 2007) and for four years after the end of the program (March 2007 to August 2011). Results: Of 64 patients, 56 were enrolled. In four years after discharge, nine patients died, six of them were from the control group and three from the study group (p = 0.151). The study group maintained glycated hemoglobin A (HbA1c) levels after PFU (8.5% vs. 8.0%, p = 0.082), while the control group showed reduced levels (9.1% vs. 8.1%; p = 0.004). Fasting glucose remained under control in the study group (149.5 mg/dL vs. 148.8 mg/dL, p = 0.884) as well as in the control group (170.7 mg/dL vs. 170.6 mg/dL, p = 0.993) after four years. However, when the groups were compared after PFU, the study group showed a significantly lower value than the control group (p = 0.047). Conclusion: Although the differences observed between the groups during PFU did not remain after four years, clinical and laboratory results did not show significant worsening in the period. (AU)
