Evidence of Cannabidiol Effectiveness Associated or Not with Tetrahydrocannabinol in Topical Administration: A Scope Review.

Cannabis sativa is a plant of the Cannabaceae family, whose molecular composition is known for its vast pharmacological properties. Cannabinoids are the molecules responsible for Cannabis sativa potential effects, especially tetrahydrocannabinol and cannabidiol. Scientific development has shown interest in the potential of cannabidiol in various health conditions, as it has demonstrated lower adverse events and great pharmacological potential, especially when administered topically. The present study aims to carry out a scoping review, focusing on the use of cannabidiol, in vivo models, for topical administration. Thus, the methodological approach used by the Joanna Briggs Institute was applied, and the studies were selected based on previously established inclusion criteria. Even though more information regarding the dose to achieve pharmacological potential is still needed, cannabidiol demonstrated potential in treating and preventing different conditions, such as glaucoma, atopic dermatitis, epidermolysis bullosa, and pyoderma gangrenosum.

Evaluation of the initial response in clinical trial efforts for COVID-19 in Brazil. / Avaliação da resposta inicial de desenvolvimento de ensaios clínicos para COVID-19 no Brasil.

OBJECTIVE: To describe the methodological characteristics and good research practices of COVID-19 interventional studies developed in Brazil in the first months of the pandemic. METHODS: We reviewed the bulletin of the National Research Ethics Committee - Coronavirus Special Edition (Comissão Nacional de Ética em Pesquisa - CONEP-COVID) (May 28, 2020) and the databases of the International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, and Brazilian Clinical Trials Registry (Registro Brasileiro de Ensaios Clínicos - ReBEC) to identify interventional studies registered in Brazil that assessed drug type, biological therapy, or vaccines. We described their methodological characteristics and calculated their power for different effect magnitudes. RESULTS: A total of 62 studies were included, 55 retrieved from the CONEP website, and 7 from registry databases. The most tested pharmacological interventions in these studies were: chloroquine/hydroxychloroquine, azithromycin, convalescent plasma, tocilizumab, sarilumab, eculizumab, vaccine, corticosteroids, anticoagulants, n-acetylcysteine, nitazoxanide, ivermectin, and lopinavir/ritonavir. Out of 22 protocols published on registry databases until May 2020, 18 (82%) were randomized clinical trials, and 13 (59%) had an appropriate control group. However, 9 (41%) of them were masked, and only 5 (24%) included patients diagnosed with a specific laboratory test (for example, reverse transcription polymerase chain reaction - RT-PCR). Most of these studies had power > 80% only to identify large effect sizes. In the prospective follow-up, 60% of the studies available at CONEP until May 2020 had not been published on any registry platform (ICTRP/ReBEC/ClinicalTrials) by July 21, 2020. CONCLUSION: The interventions evaluated during the Brazilian research response reflect those of international initiatives, but with a different distribution and a large number of studies assessing hydroxychloroquine/chloroquine. Limitations in methodological design and sample planning represent challenges that could affect the research outreach.

OBJETIVO: Descrever as características metodológicas e de boas práticas em pesquisa dos estudos de intervenção para COVID-19 desenvolvidos no Brasil nos primeiros meses da pandemia. MÉTODOS: Revisamos o boletim da Comissão Nacional de Ética em Pesquisa - edição especial Coronavírus (CONEP-COVID) (28 de maio de 2020) e as bases International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov e Registro Brasileiro de Ensaios Clínicos (ReBEC) para identificar estudos registrados no Brasil que avaliassem intervenções de tipo de medicamento, terapia biológica ou vacinas. Descrevemos as características metodológicas e calculamos o poder para diferentes magnitudes de efeito. RESULTADOS: Foram incluídos 62 estudos, 55 identificados no site da CONEP e mais sete nas bases de registro. As intervenções medicamentosas mais frequentemente testadas nesses estudos foram: cloroquina/hidroxicloroquina, azitromicina, plasma convalescente, tocilizumabe, sarilumabe, eculizumabe, vacina, corticoides, anticoagulantes, n-acetilcisteína, nitazoxanida, ivermectina e lopinavir/ritonavir. De 22 protocolos publicados até maio de 2020 nas bases de registro, 18 (82%) eram ensaios clínicos randomizados e 13 (59%) tinham grupo controle adequado. Entretanto, nove (41%) eram mascarados e somente cinco (24%) incluíam pacientes diagnosticados com teste de laboratório específico (por exemplo, transcrição reversa seguida de reação em cadeia da polimerase - RT-PCR). A maioria desses trabalhos teria poder > 80% apenas para identificar grandes tamanhos de efeito. Em seguimento prospectivo, observamos que 60% dos estudos disponíveis na CONEP até maio de 2020 não estavam em nenhuma das plataformas de registro (ICTRP/ReBEC/ClinicalTrials) até o dia 21 de julho de 2020. CONCLUSÃO: As intervenções avaliadas durante a resposta brasileira em pesquisa refletem iniciativas internacionais, porém com distribuição diferente, tendo número elevado de estudos que avaliam hidroxicloroquina/cloroquina. Limitações no delineamento metodológico e planejamento amostral representam desafios que podem afetar o alcance dos trabalhos.

Potential kidney damage associated with the use of remdesivir for COVID-19: analysis of a pharmacovigilance database.

The U.S. Food and Drug Administration (FDA) has stated that the prescription of remdesivir should be cautious for patients with estimated glomerular filtration rate (eGFR) < 30 and some studies reported risk of adverse renal events. The available information on the renal safety profile for remdesivir is limited, thus we analyzed the renal and urinary adverse reactions attributed to remdesivir reported in a large open pharmacovigilance database. We obtained reports of remdesivir and other drugs used to treat COVID-19 (tocilizumab, hydroxychloroquine, lopinavir/ritonavir) registered by September 30 2020, from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). We analyzed the reporting odds ratios (RORs) for reports of adverse renal and urinary events for remdesivir and other drugs. We found 2,922 reports with remdesivir registered in FAERS for COVID-19. Among these, 493 renal and urinary adverse effects (16.9%) were reported. The most frequent events were acute kidney injury (338; 11.6%), renal impairment (86; 2.9%), and renal failure (53; 1.8%). Versus hydroxychloroquine, lopinavir/ritonavir, or tocilizumab, the use of remdesivir was associated with an increased chance of reporting renal and urinary disorders regardless of gender and age of patients (2.53; 95%CI: 2.10-3.06). The ROR remained significant when we restricted the analysis to hydroxychloroquine (4.31; 95%CI: 3.25-5.71) or tocilizumab (3.92; 95%CI: 2.51-6.12). Our results reinforce this already reported signal, emphasizing that it could be extremely useful for health professionals who prescribe this new antiviral to treat COVID-19, mainly knowing its low efficacy.

Pharmacogenetic testing in psychiatry and neurology: an overview of reviews.

Pharmacogenetic testing is available to healthcare professionals to guide drug selection and prevent adverse events. However, its implementation in the clinical practice of psychiatry/neurology still has barriers, mainly due to a lack of evidence. We conducted a literature search on Cochrane Library, Embase and Pubmed, from their inception to 18 June 2020. We included 16 published systematic reviews. The most studied drug categories were anticonvulsants and selective serotonin reuptake inhibitors associated with human leukocyte antigen and cytochrome P450 genes (HLA-A, HLA-B, CYP2C9, CYP2D6, CYP2C19), classified as critically low quality/low quality. There is a need for more robust studies with adequate design to assess the potential benefits of adopting pharmacogenetics in health systems and services.

Even High-Quality CPGs Seldom Include Implementation Strategies.

Background: Implementation is a key step in ensuring that high-quality clinical practice guideline (CPG) recommendations are followed and have a positive impact. This step must be planned during CPG development. This study aims to inform professionals tasked with developing and implementing CPGs regarding implementation strategies and tools reported in high-quality CPGs for chronic non-communicable diseases (NCDs). Methods: NCD guidelines were selected based on Appraisal of Guideline Research and Evaluation (AGREE) II assessment. CPGs with a score of ≥60% in AGREE II domains 3 (rigor of development), 5 (applicability), and 6 (editorial independence), were considered high quality. The content related to implementation was extracted from CPG full texts and complementary materials. Implementation strategies and tools were assessed and classified using Mazza taxonomy. Results: Twenty high-quality CPGs were selected, most of which were developed by government institutions (16; 80%) with public funding (16; 80%); almost half (9; 45%) addressed the treatment of cardiovascular diseases. The countries with the most high-quality CPGs were the UK (6; 30%) and Colombia (5; 25%). These countries also had the highest average number of strategies, Colombia with 28 (SD = 1) distributed in all levels, and the UK with 15 (SD = 7), concentrating on professional and organizational levels. Although the content of the Colombian CPGs was similar regardless the disease, the CPGs from the UK were specific and contained data-based feedback reports and information on CPG compliance. Implementation strategies most frequently identified were at the professional level, such as distributing reference material (18; 80%) and educating groups of healthcare professionals (18; 80%). At the organizational level, the most frequent strategies involve changes in structure (15; 75%) and service delivery method (13; 65%). Conclusion: Countries with established CPG programs, such as the UK and Colombia, where identified as having the highest number of high-quality CPGs, although CPG implementation content had significant differences. Among high-quality CPGs, the most common implementation strategies were at the professional and organizational levels. There is still room for improvement regarding the implementation strategies report, even among high-quality CPGs, especially concerning monitoring of implementation outcomes and selection of strategies based on relevant implementation barriers.

Critical appraisal and comparison of recommendations of clinical practice guidelines for treatment of schizophrenia in children and adolescents: a methodological survey protocol.

INTRODUCTION: The number of clinical practice guidelines (CPGs) have increased substantially mainly in the paediatric area of mental health. However, little is known about the quality or how recommendations for the treatment of disorders such as schizophrenia in children and adolescents have changed over time. The aim of this study will be to assess the quality of the development of CPGs for the treatment and management of schizophrenia in children and adolescents over time using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool and to compare the recommendations and interventions described in these documents. METHODS AND ANALYSIS: CPGs will be identified using a prospective protocol through a systematic search of multiple databases (Medline, Embase, Health Systems Evidence, Epistemonikos, Lilacs, etc) and guideline websites from 2004 to December 2020. The quality of the guidelines will be assessed by three reviewers, independently using the AGREE II. CPGs will be considered of high-quality if they scored ≥60% in four or more domains of the AGREE II instrument. Non-parametric tests will be used to test for the change of quality over time. We will summarise the different evidence grading systems and compare the recommendations. ETHICS AND DISSEMINATION: Ethical approval is not required since it is a literature-based study. Future results of the research can be submitted for publication in scientific journals of high impact, peer reviewed and also published in national and international conferences. The results derived from this study will contribute to the improvement of health institutions and policies, informing about existing recommendation guidelines and about deficiencies and qualities found in those. This study may also identify key areas for future research. This study may guide the search and choice for high quality CPGs by health policy makers and health professionals and subsidise future adaptations. PROTOCOL REGISTRATION NUMBER: CRD42020164899.

[Validation of the "Conocimiento del Paciente sobre sus Medicamentos" (CPM-ES-ES) questionnaire]. / Validação do questionário "Conocimiento del Paciente sobre sus Medicamentos" (CPM-ES-ES).

This work cross-culturally adapted the Spanish questionnaire `Patients' knowledge about their medications ("Conocimiento del Paciente sobre sus Medicamentos" - CPM-ES-ES) for use in Brazil. It measures the level of medication knowledge by means of 11 questions. Eighty patients ≥ 80 years were investigated and in 39 cases the caregivers were interviewed. The evaluation of conceptual and item equivalences considered the concept of knowledge and the questions that assess it as pertinent. Semantic equivalence was obtained by the correspondence in the denotative and connotative meaning of items. The study of measurement equivalence included factorial analysis and the calculation of validity and reliability estimates. As with the original questionnaire, principal component analysis identified 4 components, however, in 2 of them there were differences regarding included items. One question was removed from this analysis due to its sample inadequacy. Medication knowledge was correlated with medication regimen complexity r = -.22, p = .046. Medication knowledge of antihypertensives was correlated with their adherence r = .70, p < .001, and blood pressure control rb = .46, p = .029. The adapted version revealed functional equivalence, therefore it can be used in the Brazilian context.

Este trabalho adaptou transculturalmente o questionário espanhol "Conocimiento del Paciente sobre sus Medicamentos" (CPM-ES-ES) para uso no Brasil. Ele mede o grau de conhecimento sobre medicamentos por meio de 11 perguntas. Oitenta pacientes ≥ 80 anos foram investigados e com 39 também foi entrevistado o cuidador. A avaliação das equivalências conceitual e de item considerou o conceito de conhecimento e as perguntas que o medem como pertinentes. A equivalência semântica foi obtida pela correspondência de significado denotativo e conotativo dos itens. O estudo da equivalência de mensuração incluiu análise fatorial e o cálculo de estimativas de validade e confiabilidade. Semelhante ao questionário original, a análise de componentes principais identificou 4 componentes, porém, em 2 deles houve diferenças nos itens incluídos. Uma pergunta foi removida desta análise devido à sua inadequação amostral. O conhecimento sobre medicamentos esteve correlacionado à complexidade da prescrição r = -0,22, p = 0,046. O conhecimento sobre anti-hipertensivos esteve correlacionado à sua adesão r = 0,70, p < 0,001, e ao controle da pressão arterial rb = 0,46, p = 0,029. A versão adaptada apresentou equivalência funcional de modo que pode ser usada no contexto brasileiro.

Comparison of the methodological quality and transparency of Brazilian practice guidelines.

This study aims to compare the differences between clinical practice guidelines (CPGs) of the Ministry of Health (MoH) and those of other Brazilian health institutions. A systematic review of Brazilian CPGs was carried out. CPGs with recommendations for the pharmacological treatment of non-communicable disease (NCDs) were included. CPG methodological quality and transparency was independently assessed by 2 reviewers using the AGREE II. CPGs were rated as high, moderate, and low quality (ranging from A to C). Twenty-six CPGs were assessed for quality. MoH CPGs were published more recently, and were of better quality than the others: 6/6 (100%) were rated as Moderate-A. Although CPGs presented a wide range of methodological quality and transparency, MoH CPGs presented better consistency in the preparation method. To avoid confusion and to improve the quality of care within finite resources in Brazil, and to avoid potential bias, conflicts of interest, national CPGs used within SUS should be developed by Conitec with partners who have no conflict of interest.

Factors Associated With High-Quality Guidelines for the Pharmacologic Management of Chronic Diseases in Primary Care: A Systematic Review.

Importance: As the rate of publication of new and sometimes conflicting medical research increases, clinicians rely heavily on clinical practice guidelines (CPGs) to inform practice. However, CPGs are of widely variable quality, and there are no existing objective measures to rate the quality of CPGs. Objective: To systematically assess 421 CPGs for the management of common noncommunicable diseases in primary care using the validated Appraisal of Guidelines for Research and Evaluation Instrument, version II (AGREE-II) tool and elucidate the factors associated with quality of CPGs. Evidence Review: MEDLINE, Embase, the Cochrane Library, and 12 websites for CPGs were searched for CPGs for the management of common noncommunicable diseases in primary care published between January 1, 2011, and August 30, 2017. The assessment of the quality of CPGs was performed by 3 appraisers using the 6 domains of the AGREE-II instrument. A multiple logistic regression was performed to identify factors associated with quality of CPGs. Findings: Of the 421 CPGs reviewed, 23.5% (99) were classified as high quality. Among included guidelines, clarity of presentation (70%) and scope and purpose (61%) had the highest median AGREE-II scores. The domains with the lowest median scores were applicability (22%) and rigor of development (33%). Factors associated with high-quality CPGs included having more than 20 authors (odds ratio, 9.08; 95% CI, 3.35-24.62), development at governmental institutions (odds ratio, 10.38; 95% CI, 2.72-39.60), and reporting funding (odds ratio, 10.34; 95% CI, 4.77-22.39). Year of publication, region, guideline version, and scope were not associated with quality among included CPGs. Conclusions and Relevance: Primary care professionals and policymakers should be aware that CPGs in primary care are of widely variable quality, with less than 25% of included CPGs rated as high quality. High-quality CPGs were associated with a higher number of authors, governmental institutions, and the report of funding. Region of origin was not associated with quality of CPGs, which suggests that the improvement of the quality of CPGs should be an international concern.

Analysis of reported adverse liver reactions associated with drugs used to treat patients with coronavirus disease 2019

Abstract Hepatic injury has been documented in patients with coronavirus disease 2019 (COVID-19). However, pharmacotherapy can frequently impact liver alterations, given the known hepatotoxic potential of drugs not effective to treat COVID-19. The objective of the present study was to evaluate reports of suspected liver reactions to drugs used for treating COVID-19, compare their use for other indications among patients with COVID-19, and assess possible interactions between them. We obtained reports on drugs used to treat COVID-19 (tocilizumab, remdesivir, hydroxychloroquine, and/or lopinavir/ritonavir), registered on June 30, 2020, from the Food and Drug Administration Adverse Event Reporting System (FAERS) Public Dashboard. We then analyzed the risk of developing liver events with these drugs by calculating the reported odds ratios (ROR). We identified 662, 744, and 1381 reports related to tocilizumab, lopinavir/ ritonavir, and hydroxychloroquine use, respectively. The RORs (95% confidence intervals) were 6.32 (5.28-7.56), 6.12 (5.22-7.17), and 9.07 (8.00-10.29), respectively, demonstrating an increased risk of liver events among patients with COVID-19 when compared with uninfected patients. The elevated risk of reporting adverse liver events in patients with COVID-19 who receive these drugs, alone or in combination, highlights the need for careful drug selection and efforts to reduce drug combinations without notable benefits. Similar to any other condition, the use of drugs without established efficacy should be avoided.

Vancomycin use in a hospital with high prevalence of methicillin-resistant Staphylococcus aureus: comparison with Hospital Infection Control Practices Advisory Committe Guidelines (HICPAC).

This study evaluates vancomycin prescribing patterns in a tertiary-care hospital, with high prevalence of methicillin-resistant Staphylococcus aureus, comparing with the guidelines proposed by the Hospital Infection Control Practices Advisory Committee. The study was conducted in a 930-bed tertiary-care hospital, during 40 days (March 10 to April 30, 2003). Data were collected of all patients given vancomycin, using a standardized chart-extraction form designed. Inappropriate use was subdivided in five categories: empiric therapy without risk factors; continued empiric use for presumed infections in patients whose cultures were negative for beta-lactam-resistant Gram-positive microorganisms; treatment of infections caused by beta-lactam-sensitive Gram-positive microorganisms, without allergy history to beta-lactam antimicrobials; treatment in response to a single blood culture positive for coagulase-negative staphylococcus, if other blood cultures taken during the same time frame were negative; systemic or local prophylaxis for infection or colonization of indwelling central or peripheral intravascular catheters. Of 132 orders, 126 (95.4%) were considered to have been appropriate. Of these 126 prescriptions, 31 (24.6%) were administered for treatment of proven Gram-positive infections (78.1% of those were MRSA), 1 (0.8%) for beta-lactam allergy and 95 (75.4%) for empiric treatment of suspected Gram-positive infections. The majority of the patients (88.6%) have used antimicrobial recently (3 months). The mean pre-treatment hospitalization period was 14 +/- 15 days. Of the 132 treatments, 105 (79.5%) were nosocomial infections. In the institution analyzed, the vancomycin use was considered conscientious. Reduction in use of glycopeptide may be obtained by adaptations the CDC criteria, or by improvement of diagnostic criteria.

Pharmacist's contribution to the promotion of access and rational use of essential medicines in SUS. / A contribuição do farmacêutico para a promoção do acesso e uso racional de medicamentos essenciais no SUS.

OBJECTIVE:: to describe the pharmaceutical inclusion process in a Basic Health Unit multidisciplinary team and evaluate results related to rational use and promotion of access to essential medicines. METHODS:: This is a descriptive, cross-sectional study conducted in a primary care health unit in the city of São Paulo. Pharmacist's activities were evaluated regarding the service structure and organization and prescribing quality improvement, guidance method creation, and implementation of clinical pharmacy service. Data measured before and after the interventions and between 2010 and 2011 were analyzed using Pearson´s chi-square test with a significance level of 5%, and odds ratio. RESULTS:: Pharmacist's activities had statistically significant result in drug shortage reduction; prescribing quality improvement associated with an increased proportion of prescriptions met; decrease in the total of prescribed drugs among patients receiving pharmacotherapeutic follow-up and, comparing the years 2010 and 2011, changes in the pharmacotherapy recommendations have gained increased acceptance level. CONCLUSIONS:: Pharmacist's activities may effectively provide rational use and promotion of access to essential medicines.

Training of pharmacy technicians for dispensing drugs in Primary Health Care. / Capacitação e intervenções de técnicos de farmácia na dispensação de medicamentos em Atenção Primária à Saúde.

Few Brazilian articles discuss the importance of pharmacy technicians who offer direct assistance to patients. This paper describes an experience of the training of pharmacy technicians in drug dispensing. A descriptive, cross-sectional study was conducted in the primary healthcare setting. The technicians were trained by the pharmacist to advise patients at the time of drug dispensing and to screen cases that needed pharmaceutical consultation. Problems were identified by verifying the prescription and return date for dispensing the medication as well as through direct questioning of the patients. Flowcharts for problem identification and intervention were created for use by the technicians. After training, pharmacy technicians identified 3944 problems, the most common of which were the use of a lower dosage than that prescribed (26%) and non-adherence to pharmacological treatment. The findings of the present study demonstrate the importance of training pharmacy technicians with regard to dispensing drugs so that they can assist pharmacists in the process of identifying and solving drug-related problems, thereby making them active members of the care process in the public health system.

Recommendations for the development of Clinical Practice Guidelines / Recomendações para o desenvolvimento de Diretrizes de Prática Clínica

Clinical practice guidelines are statements that include recommendations intended to optimize patient care, are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options, and ensure that the best available clinical knowledge is used to provide effective and quality care. They can reduce inappropriate care and variability in clinical practice and can support the translation of new research knowledge into clinical practice. Recommendations from clinical practice guidelines can support health professionals by facilitating the decision-making process, empowering them to make more informed health care choices, clarifying which interventions should be priorities based on a favorable tradeoff, and discouraging the use of those that have proven ineffective, dangerous, or wasteful. This review aims to summarize the key components of high-quality and trustworthy guidelines. Articles were retrieved from various libraries, databases, and search engines using free-text term searches adapted for different databases, and selected according to author discretion. Clinical practice guidelines in geriatrics can have a major impact on prevention, diagnosis, treatment, rehabilitation, health care, and the management of diseases and conditions, but they should only be implemented when they have high-quality, rigorous, and unbiased methodologies that consider older adult priorities and provide valid recommendations.

As diretrizes de prática clínica são declarações que incluem recomendações destinadas a otimizar o atendimento ao paciente, informadas por uma revisão sistemática de evidências e uma avaliação dos benefícios e malefícios de opções alternativas de atendimento, garantindo que o melhor conhecimento clínico disponível seja usado para fornecer atendimento eficaz e de qualidade. Elas contribuem reduzindo os cuidados inadequados e a variabilidade na prática clínica e podem apoiar a tradução de novos conhecimentos de pesquisa. As recomendações dessas diretrizes podem apoiar os profissionais de saúde, facilitando o processo de tomada de decisão, capacitando-os a fazer escolhas de cuidados de saúde mais informadas, esclarecendo quais intervenções devem ser prioritárias com base em um trade-off favorável e desencorajando o uso daquelas comprovadamente ineficazes, perigosas ou que consistam em desperdício. Esta revisão visa resumir os principais componentes de diretrizes confiáveis e de alta qualidade. Os artigos foram recuperados de várias bibliotecas, bancos de dados e mecanismos de busca por meio de buscas de termos de texto livre adaptados para diferentes bancos de dados e selecionados de acordo com o critério do autor. As diretrizes de prática clínica em geriatria podem ter grande impacto na prevenção, diagnóstico, tratamento, reabilitação, assistência à saúde e manejo de doenças e condições, mas só devem ser implementadas quando tiverem metodologias de alta qualidade, rigorosas e imparciais, que considerem as prioridades da pessoa idosa e forneçam recomendações válidas.

Methodological quality and transparency of clinical practice guidelines for the pharmacological treatment of non-communicable diseases using the AGREE II instrument: a systematic review protocol.

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of death worldwide. Clinical practice guidelines (CPGs) constitute an important tool for the promotion of evidence-based health, which may improve healthcare outcomes for individuals with NCDs. Studies have shown that many CPGs have poor or moderate quality. Therefore, the aim of the proposed study is to systematically identify and appraise CPGs for pharmacological treatment of the most prevalent NCDs in primary care. METHODS: A comprehensive literature search will be conducted in the following databases: MEDLINE, Embase and Cochrane Library. Twelve databases specific to CPGs will also be searched. Three appraisers will assess the quality of the CPGs using the Appraisal of Guidelines Research and Evaluation (AGREE) Instrument, version II. The AGREE II results will be checked for discrepancies. Differences between scores equal than or greater to 2 will be considered discrepant and the appraisers will decide the final score by consensus. If no consensus is reached, a fourth appraiser will decide the score. According to the AGREE II User's Manual, the six domains of the instrument are independent. Thus, each domain score will be calculated by the sum of the individual item scores and scaling the total as a percentage of the maximum possible score for the domain. DISCUSSION: The AGREE II instrument will be applied to evaluate the quality of CPGs and contribute to enhance the discussion and development of guidelines of high quality. The findings will be submitted for publication in high-impact, peer-reviewed scientific journals and will also be disseminated at international conferences.

Evaluation of drug prescription quality indicators in a primary health care facility with different models of health care. / Avaliação de indicadores de qualidade de prescrição de medicamentos em uma unidade de atenção primária com diferentes modelos de atenção.

OBJECTIVE: to describe drug prescription indicators in a primary health care facility with different models of health care. METHODS: this was a descriptive study using secondary data of prescriptions with regard to quality indicators in a health facility that has three health care models: Outpatient Medical Care (OMC), Primary Health Care Unit (PHU) and Family Health Strategy (FHS) in Vila Nova Jaguaré OMC/PHU in São Paulo-SP, Brazil, from July to October 2011. RESULTS: 16,720 prescriptions were studied; the proportion of drugs provided through the Municipal List of Essential Drugs (Remume) was higher for FHS prescriptions (98.9%), compared to PHU (95.6%) and OMC (95.7%); similarly, both the use of the generic name of the drugs and the proportion of drugs provided was higher among ESF prescriptions (98.9% and 96.1%, respectively), compared with PHU (94.4 % and 92.9%) and OMC (94.0% and 92.7 %). CONCLUSION: all the prescription indicators show better results for FHS.

Potential kidney damage associated with the use of remdesivir for COVID-19: analysis of a pharmacovigilance database / Potencial nefropatia associada ao uso do remdesivir para COVID-19: análise de uma base de dados de farmacovigilância / Potenciales lesiones renales asociadas con el uso de remdesivir para la COVID-19: análisis de una base de datos de farmacovigilancia

Abstract: The U.S. Food and Drug Administration (FDA) has stated that the prescription of remdesivir should be cautious for patients with estimated glomerular filtration rate (eGFR) < 30 and some studies reported risk of adverse renal events. The available information on the renal safety profile for remdesivir is limited, thus we analyzed the renal and urinary adverse reactions attributed to remdesivir reported in a large open pharmacovigilance database. We obtained reports of remdesivir and other drugs used to treat COVID-19 (tocilizumab, hydroxychloroquine, lopinavir/ritonavir) registered by September 30 2020, from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). We analyzed the reporting odds ratios (RORs) for reports of adverse renal and urinary events for remdesivir and other drugs. We found 2,922 reports with remdesivir registered in FAERS for COVID-19. Among these, 493 renal and urinary adverse effects (16.9%) were reported. The most frequent events were acute kidney injury (338; 11.6%), renal impairment (86; 2.9%), and renal failure (53; 1.8%).

The ROR remained significant when we restricted the analysis to hydroxychloroquine (4.31; 95%CI: 3.25-5.71) or tocilizumab (3.92; 95%CI: 2.51-6.12). Our results reinforce this already reported signal, emphasizing that it could be extremely useful for health professionals who prescribe this new antiviral to treat COVID-19, mainly knowing its low efficacy.

Resumo: De acordo com a Agência de Controle de Alimentos e Medicamentos dos Estados Unidos (FDA), a prescrição do remdesivir deve ser feita com cautela em pacientes com taxa de filtração glomerular estimada (TFGe) < 30, sendo que diversos estudos relatam risco de eventos adversos renais. São limitados os dados disponíveis sobre o perfil de segurança renal do remdesivir. Assim, analisamos as reações adversas renais e urinárias atribuídas ao remdesivir e notificadas em um grande base de dados abertos de farmacovigilância. Obtivemos notificações sobre remdesivir e outros medicamentos usados para tratar a COVID-19 (tocilizumabe, hidroxicloroquina, lopinavir/ritonavir) registradas até 30 de setembro de 2020 do Sistema de Notificação de Eventos Adversos da FDA (FAERS). Analisamos as razões de chances de notificação (RORs) para notificações de eventos adversos renais e urinários referentes ao remdesivir e outros medicamentos. Encontramos 2.922 notificações sobre remdesivir registradas no FAERS para COVID-19. Entre esses casos, foram notificados 493 efeitos adversos renais e urinários (16,9%). Os eventos mais frequentes foram lesão renal aguda (338; 11,6%), comprometimento renal (86; 2,9%) e insuficiência renal (53; 1,8%). Comparado com a hidroxicloroquina, lopinavir/ritonavir ou tocilizumabe, o uso do remdesivir esteve associado com um aumento das chances de notificação de transtornos renais e urinários, independentemente do sexo e idade dos pacientes (2,53; IC95%: 2,10-3,06). A ROR permaneceu significativo quando limitamos a análise à hidroxicloroquina (4,31; IC95%: 3,25-5,71) ou ao tocilizumabe (3,92; IC95%: 2,51-6,12). Nossos resultados corroboram outros estudos e destacam a utilidade para profissionais da saúde que usam esse novo antiviral para tratar a COVID-19, sobretudo em função de sua baixa eficácia.

Resumen: La Agencia Americana de Control de Alimentos y Medicamentos (FDA) ha destacado que la prescripción de remdesivir debe ser prudente con pacientes con tasa de filtración glomerular estimada (TGFe) < 30; además, algunos estudios informaron del riesgo de reacciones adversas renales. La información disponible sobre el perfil de seguridad renal, en el caso del remdesivir, es limitada. Por ello, analizamos las reacciones adversas renales y urinarias atribuidas al remdesivir e notificadas en una extensa base de datos abierta de farmacovigilancia. Obtuvimos las notificaciones de remdesivir y otros medicamentos usados para tratar la COVID-19 (tocilizumab, hidroxicloroquina, lopinavir/ritonavir) registrados el 30 de septiembre de 2020 por el Sistema de Notificación de Eventos Adversos de la FDA (FAERS). Analizamos las odds ratios informadas (RORs) en el caso de informes de eventos adversos renales y urinarios adversos relacionados con el remdesivir y otros medicamentos. En el FAERS, encontramos 2.922 notificaciones de remdesivir registradas como medicament sospechoso usado en COVID-19. De estos, habían 493 con efectos renales y urinarios adversos (16,9%). Los efectos adversos más frecuentes fueron lesiones renales agudas (338; 11,6%), insuficiencia renal (86; 2,9%), y fallo renal (53; 1,8%). Frente a hidroxicloroquina, lopinavir/ritonavir, o tocilizumab, el uso de remdesivir se asoció con un riesgo mayor de notificar alteraciones renales y urinarios, independientemente del género y edad de los pacientes (2,53; IC95%: 2,10-3,06). La ROR permaneció significativo al restringir el análisis a la hidroxicloroquina (4,31; IC95%: 3,25-5,71) o tocilizumab (3,92; IC95%: 2,51-6,12). Nuestros resultados corroboran datos previos, algo que podría ser extremadamente útil para los profesionales de la salud que decidan usar este nuevo antiviral para tratar la COVID-19, sobre todo conociendo su baja eficacia.

Conhecimento inadequado sobre medicamentos prescritos e seus preditores em pacientes muito idosos e seus cuidadores / Inadequate knowledge of prescription drugs and their predictors in very old patients and their caregivers

Resumo Objetivo Identificar preditores do conhecimento inadequado sobre medicamentos prescritos a pacientes ambulatoriais muito idosos e seus cuidadores. Método O conhecimento sobre os medicamentos prescritos para 80 pacientes com 80 anos ou mais de idade foi avaliado por meio de um questionário validado, em uma entrevista realizada com os pacientes ou seus cuidadores (quando os pacientes apresentavam dificuldades de comunicação, demência ou qualquer necessidade de assistência para ajudá-los a usar medicamentos). Dois modelos de regressão logística hierárquica avaliaram a associação entre conhecimento inadequado sobre medicamentos e variáveis ​​sociodemográficas e medicamentosas. Resultados Trinta e nove (48,8%) entrevistados eram cuidadores. Conhecimento inadequado foi encontrado em 81,5% (404/496) dos medicamentos prescritos. Forma de administração, Dose, Frequência e Duração do Tratamento foram os aspectos de maior conhecimento, enquanto Reações Adversas, Precauções, Interações e Contraindicações, os de menor. No primeiro modelo, o conhecimento inadequado foi associado à escolaridade do ensino fundamental completo ao médio incompleto (Razão de Chances (RC):0,12; p=0,018), do médio ao superior incompleto (RC:0,12; p<0,001), superior completo (RC:0,13; p<0,001), agentes que atuam no sistema renina-angiotensina (SRA) (RC:0,30; p=0,001), diuréticos (RC:0,31; p=0,013) e antitrombóticos (RC:12,59; p=0,027). No segundo modelo, os preditores foram cuidadores (RC:0,17; p<0,001), agentes que atuam no SRA (RC:0,33; p=0,002), diuréticos (RC:0,35; p=0,024) e antitrombóticos (RC:12,57; p=0,026). Conclusão A maioria dos medicamentos prescritos para pessoas muito idosas é pouco conhecida. Além disso, o aconselhamento acerca de informações sobre medicamentos deve ser mais intensivo para os pacientes do que para seus cuidadores, com foco em informações de segurança e ser direcionado a antitrombóticos.

Abstract Objective Identify predictors of inadequate knowledge about the medication prescribed to very old outpatients and their caregivers. Method The knowledge on the medication prescribed for 80 patients aged 80 years and over was assessed using a validated questionnaire to interview patients or their caregivers (when patients had communication difficulties, dementia, or any need for care to help them take the medication). Two hierarchical logistic regression models assessed the association between inadequate knowledge of the medication and sociodemographic and drug variables. Results Thirty-nine (48.8%) respondents were caregivers. Inadequate knowledge was found in 81.5% (404/496) of medication prescribed. Route of Administration, Dose, Frequency, and Duration of Treatment were the aspects of greatest knowledge, whereas Adverse Effects, Precautions, Interactions, and Contraindications were the least known ones. In the first model, inadequate knowledge was associated to the level of education from complete elementary school to incomplete high school (Odds Ratio (OR): 0.12; p=0.018), from high school to incomplete higher education (OR: 0.12; p<0.001), complete higher education (OR: 0.13; p<0.001), agents acting on the renin-angiotensin system (RAS) (OR: 0.30; p=0.001), diuretics (OR: 0.31; p=0.013) and antithrombotic (OR: 12.59; p=0.027). In the second model, the predictors were caregivers (OR: 0.17; p<0.001), agents working in the RAS (OR: 0.33; p=0.002), diuretics (OR: 0.35; p=0.024) and antithrombotic (OR: 12.57; p=0.026). Conclusion Most of the medication prescribed for very old people is not very well known. Also, advice on drug information should be more intensive to patients than to their caregivers, with a focus on safety information and targeted at antithrombotics.

Impacto econômico das ações judiciais para o fornecimento de medicamentos no Estado de São Paulo / Economic impact of lawsuits for drug supply in the State of São Paulo

Objetivos: compreender a participação das despesas com medicamentos judicializados nas despesas totais liquidadas com medicamentos (DTLM) no Estado de São Paulo (SP). SP. Métodos: realizou-se análise exploratória de dados do Sistema de Informações Gerenciais da Execução Orçamentária (Sigeo) e do Sistema de Informação de Orçamento Público em Saúde (Siops), de 2010 a 2018. Resultados: no período estudado, as DTLM em SP superaram 11 bilhões de reais, apresentando tendência decrescente em valores globais e na participação percentual em relação à despesa total com saúde (de 11,32% em 2010 para 8,95% em 2018). De 2016 a 2018, 17% das DTLM foram destinadas às ações judiciais (R$ 679.935.967,31), sendo a tendência crescente. Discussão: a representatividade dos medicamentos judicializados na DTLM alerta para questões de custo, mas também para a segurança do paciente e sustentabilidade das políticas públicas de saúde, pois o rol também contempla medicamentos novos, para os quais a superioridade em efetividade e segurança ainda não foram comprovadas comparando-se às alternativas disponíveis, e/ou com uso off-label. Conclusões: as demandas judiciais por medicamentos não têm levado ao aumento da destinação de recursos para sua aquisição, mas à concorrência por recursos originalmente destinados à política de assistência farmacêutica, com redução da participação percentual dos medicamentos das listas oficiais do Sistema Único de Saúde (SUS) a cada ano.

Objective: to understand the participation of expenses with judicialized medicines in total expenditure on drugs (DTLM) in São Paulo State (SP). Methods: it was conducted an exploratory analysis of data from Sistema de Informações Gerenciais da Execução Orçamentária (Sigeo) and Sistema de Informação de Orçamento Público em Saúde (Siops) from 2010 to 2018. Results: in this period, DTLM in SP exceeded 11 billion of reais, showing a downward trend in global values and percentage share in relation to total health expenditure (from 11.32% in 2010 to 8.95% in 2018). From 2016 to 2018, 17% of DTLM were destined to lawsuits (R$ 679,935,967.31), with a growing trend. Discussion: the representativeness of judicialized drugs in DTLM warns of cost issues, but also for patient safety and sustainability of public health policies, because this list also includes new drugs, which have not been proved superior in effectiveness and safety yet, comparing to available alternatives, and/or off label use. Conclusions: the legal demands for medicines have not led to an increase in the allocation of funds for their purchase, but to competition for resources originally destinated for the pharmaceutical services policy, with a reduction in the percentage participation of medicines from SUS official lists each year.

Objetivos: comprender la participación de los gastos con drogas judicializadas en los gastos totales con drogas (DTLM) en el Estado de São Paulo (SP). Métodos: se realizó un análisis exploratorio de datos del Sistema de Informações Gerenciais da Execução Orçamentária (Sigeo) y el Sistema de Informação de Orçamento Público em Saúde (Siops) de 2010 a 2018. Resultados: en este período, DTLM en SP superó los 11 mil millones de reales, mostrando una tendencia a la baja en los valores globales y la participación porcentual en relación con el gasto total en salud (del 11.32% en 2010 al 8.95% en 2018). De 2016 a 2018, el 17% de DTLM se destinó a estas demandas (R$ 679,935,967.31), con una tendencia creciente. Discusión: la representatividad de los medicamentos judicializados en DTLM advierte sobre los costos, pero también sobre la seguridad del paciente y la sostenibilidad de las políticas de salud pública, porque esta lista también incluye nuevos medicamentos, que aún no han demostrado ser superiores en comparación de efectividad y seguridade a alternativas disponibles, y/o uso off-label. Conclusiones: los pleitos de medicamentos no han llevado a un aumento en la asignación de fondos para su compra, sino a la competencia por los recursos originalmente destinados a la política de asistencia farmacéutica, con una reducción en el porcentaje de participación de medicamentos de las listas oficiales del SUS cada año.
