Impact of the insertion of the clinical pharmacist in the Allogeneic Hematopoietic Stem Cells Transplantation team.

INTRODUCTION: Allogeneic Hematopoietic Stem Cells Transplantation (allo-HSCT) is capable of curing patients with neoplastic or non-neoplastic hematologic disorders or of prolonging their survival. This study assessed if the insertion of the clinical pharmacist in the allo-HSCT team modified the outcomes: transplantation-related mortality, grafting failure, incidence of Graft versus Host Disease, hospitalization time, time for grafting, number of readmissions, number of drug-related problems (DRPs), adherence and knowledge about pharmacotherapy. METHODS: Interventional study with historical control carried out in an allo-HSCT unit, in which the intervention group (IG) included 33 individuals who received pharmacotherapy follow-up. Control Group (CG) consisted of 28 individuals. RESULTS: A total of 250 DRPs were identified, 59 team's doubts were clarified, and 309 interventions were conducted in the IG. The DRPs mainly arose from safety (51.60%) and effectiveness (38.40%) problems. A mean of 9.36 (SD = 6.97) interventions per patient was obtained, mainly including dose reductions (19.09%), adjustments in administration time (18.12%), educational activities (15.21%) and drug removal (10.68%). Clinical significance of the interventions was considered high (75.7% extremely significant, very significant or significant), as well as their acceptability (89.7% accepted). Each patient attended a mean of 4.68 pharmaceutical consultations (SD = 1.91) after hospital discharge, presenting increase in knowledge (p = 0.0001) and in adherence (p = 0.0115). There was no evidence of differences between the groups in the other outcomes analyzed. CONCLUSIONS: The pharmacotherapy follow-up allowed detecting several DRPs and performing interventions of high clinical relevance and acceptability, in addition to improving adherence and individualizing the pharmacotherapy.

Can pharmacotherapeutic follow-up after allogeneic hematopoietic stem cell transplantation improve medication compliance?

BACKGROUND: Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) is currently one of the most effective therapies in onco-hematology. For the treatment of the disease and prevention of such complications, a complex pharmacotherapeutic regimen is employed. Non-compliance is prevalent among adolescents and young adults with chronic hematological diseases, being reported by up to 50% of the patients. OBJECTIVE: To evaluate the results of pharmacotherapeutic follow-up on medication compliance and on the knowledge about pharmacotherapy of patients who underwent allo-HSCT. METHODS: A single-arm, open-label and non-randomized intervention study developed in an allo-HSCT outpatient clinic. The participants attended pharmaceutical consultations and had their knowledge about pharmacotherapy and medication compliance measured by MedTake and Brief Medication Questionnaire (BMQ), respectively. RESULTS: A total of 27 patients attended pharmaceutical consultations (4.81 consultations/patient; SD = 1.80). There was an improvement in medication compliance and in knowledge between the first and last consultations (p < 0.05). In the final consultation, 70.37% of the patients showed compliance, with a knowledge rate of 98.35% (SD = 3.63). Non-compliant individuals presented a greater tendency to hospital readmissions. There was no relationship between medication compliance and sociodemographic variables, graft-versus-host disease, and knowledge about pharmacotherapy. CONCLUSIONS: Pharmacotherapeutic follow-up contributed to improving medication compliance. Knowledge about pharmacotherapy alone does not translate into behaviors, which corroborates the complexity of the biopsychosocial factors associated with medication compliance.

Contribution of Pharmaceutical Care to Person-centered Health Care and the Safety of Pharmacotherapy for Hospitalized Older Individuals in Brazil: An Investigative Single-arm Intervention Trial.

BACKGROUND: Adverse drug events (ADE) and medication errors (ME) provide large numbers of victims. Older people are more susceptible to these events, due to the continuing search for several chronic degenerative disease treatments. The Third Global Patient Safety Challenge announced the objective of reducing unnecessary polypharmacy, encouraging deprescription, and aiming to ensure the prescription of medications in an appropriate manner, based on the best evidence and taking into account the individual factors of people. OBJECTIVE: To evaluate whether Pharmaceutical Care (PC), when inserted in a geriatric ward and the context of person-centered health care, cooperates with the safety of pharmacotherapy in older individuals in Brazil. METHODS: This is an investigative, single-arm, preliminary study. INCLUSION CRITERIA: individuals aged ≥60 years and admitted to the geriatric ward between August 2019 to January 2020. The PC (with the practice of pharmacotherapeutic follow-up, medication reconciliation, and pharmacotherapy review) was made available to identify ADE and ME, as well as the associated factors and clinical outcomes, were analyzed. RESULTS: 60 participants were included. It was found that, on hospital admission, 93.3% of them were polymedicated and 86.7% had a history of using potentially inappropriate medications (PIM). ADE and ME were detected in 43 individuals (71.7%) and, in total, 115 incidents were identified, with drugs that act on the nervous system associated with them (31.9%). Acceptance of the PC's recommendations reached the rate of 85.2%. Polypharmacy (p=0.03) and the presence of multiple diseases (p=0.03) had an effect on the presentation of ADE and ME. The number of medications in use decreased in the comparison between admission and hospital discharge (p<0.0001). CONCLUSION: This investigative study indicated that ADE and ME are linked to the polypharmacy in use at the beginning of hospitalization. On the other hand, we showed that the PC (inserted in the multidisciplinary team) contributed to the deprescribing of medications at hospital discharge. Therefore, the PC can provide improvements in this scenario.

Selection dynamics of HCV genotype 3 resistance-associated substitutions under direct-acting antiviral therapy pressure

ABSTRACT The chronic hepatitis C (CHC) treatment is currently based on the use of direct-acting antivirals (DAAs), and patients infected with hepatitis C virus genotype 3 (GT3) have emerged as a more difficult-to-cure population. The NS5A inhibitor daclatasvir (DCV) and sofosbuvir (SOF), an NS5B viral polymerase inhibitor, are among the drugs that compose more effective and safer treatment regimens. The virus genetic variability is related to resistance-associated substitutions (RASs) that adversely impact DAAs effectiveness. The aims of this study were to analyze the association of NS5A and NS5B RASs and other clinical factors with DAAs regimens effectiveness in patients with GT3 CHC infection. This was a prospective cohort study performed in a Brazilian university hospital. Individuals older than 18 years with GT3 CHC treated with SOF + DCV ± ribavirin (RBV) or SOF + peginterferon (PEG) + RBV were included. Blood samples were collected at baseline and post-treatment. A total of 121 patients were included. Sustained virological response rates were 87.6% for the SOF + DCV ± RBV group and 80.0% for the SOF + PEG + RBV arm. Cirrhosis, prior treatment with interferon/PEG + RBV, and baseline NS5A RAS were associated with higher risk of treatment failure. The NS5A analysis suggested that A30K, Y93H, and RAS at site 62 were related to failure. Interestingly, a likely compensatory effect was shown between A30K and A62T. Emergence of Y93H was always associated with RAS at position 62. The RASs dynamics comprehension is an important tool to indicate more effective treatment for GT3 patients.

Eventos adversos no sistema nervoso central potencialmente relacionados aos medicamentos utilizados na COVID-19: revisão de escopo / Central nervous system adverse events potentially associated with drugs used for COVID-19: scoping review / Eventos adversos en el sistema nervioso central potencialmente relacionados con los medicamentos para tratar la COVID-19: revisión exploratoria

RESUMO Objetivo. Identificar eventos adversos no sistema nervoso central (SNC) potencialmente associados ao uso de medicamentos para profilaxia ou tratamento da COVID-19, bem como caracterizar os indivíduos acometidos. Métodos. Desenvolveu-se uma revisão de escopo a partir de estratégia de busca nas bases de dados PubMed, EMBASE, SciELO, Scopus, Cummulative Index to Nursing and Allied Health Literature (CINAHL) e Biblioteca Virtual em Saúde (BVS). Foram incluídos estudos com indivíduos que utilizaram medicamentos como medida profilática ou curativa para COVID-19 e que apresentaram ao menos um evento adverso no SNC. Foram excluídos os artigos que reportaram eventos adversos no SNC potencialmente associados a medicamentos para outras condições de saúde. Resultados. Recuperaram-se 1 547 artigos, dos quais oito atenderam aos critérios de elegibilidade. Em sete estudos, o desenho foi do tipo observacional. Foram analisados 3 035 indivíduos, dos quais 1 701 eram profissionais da saúde e 1 978, mulheres. A terapia mais utilizada foi a curativa (n = 5), com hidroxicloroquina, cloroquina, lopinavir/ritonavir e azitromicina. Os eventos adversos comumente descritos foram dor de cabeça, tontura, distúrbios de humor e sonolência. Suicídio foi o evento grave mais frequente. Seis eventos foram inesperados para hidroxicloroquina, cloroquina e doxiciclina (mioclonias, tremor, distúrbio de marcha, disgeusia, hiperidrose e inquietação). Conclusão. Os eventos adversos no SNC foram inespecíficos e, geralmente, potencialmente associados ao uso de hidroxicloroquina em monoterapia ou em associação para tratamento curativo da COVID-19. Os dados corroboram a relação desfavorável de risco/benefício desses medicamentos na prevenção e no manejo dos sinais e sintomas da infecção por SARS-CoV-2.

ABSTRACT Objective. To identify central nervous system (CNS) adverse events potentially associated with prophylaxis or drug treatment for COVID-19, and to describe the characteristic of the individuals affected. Methods. A scoping review was performed using a search strategy to retrieve articles from PubMed, EMBASE, SciELO, Scopus, CINAHL and BVS databases. Studies reporting on individuals receiving prophylactic or curative drugs for COVID-19 with at least one CNS adverse event were included. Articles reporting on CNS adverse events associated with medication for other health conditions were excluded. Results. The search retrieved 1 547 articles, eight of which met the inclusion criteria. Seven studies had an observational design. A total of 3 035 individuals were assessed, of whom 1 701 were health care professionals and 1 978 were women. Curative treatment with hydroxychloroquine, chloroquine, lopinavir/ritonavir, and azithromycin was the most frequent (n = 5). The most common adverse events were headache, dizziness, mood disturbances, and drowsiness. Suicide was the most frequent severe event. Six adverse events were unexpected for hydroxychloroquine, chloroquine, and doxycycline. Conclusion. Potential CNS adverse events were unspecific and in general potentially associated with the use of hydroxychloroquine (monotherapy or associated with antibiotics). The data confirm the unfavorable risk/benefit profile of these drugs for the prevention and management of signs and symptoms of SARS-CoV-2 infection.

Cost-benefit analysis of pharmacist interventions over 36 months in a university hospital

ABSTRACT OBJECTIVE: To perform a cost-benefits analysis of a clinical pharmacy (CP) service implemented in a Neurology ward of a tertiary teaching hospital. METHODS: This is a cost-benefit analysis of a single arm, prospective cohort study performed at the adult Neurology Unit over 36 months, which has evaluated the results of a CP service from a hospital and Public Health System (PHS) perspective. The interventions were classified into 14 categories and the costs identified as direct medical costs. The results were analyzed by the total and marginal cost, the benefit-cost ratio (BCR) and the net benefit (NB). RESULTS: The total 334 patients were followed-up and the highest occurrence in 506 interventions was drug introduction (29.0%). The marginal cost for the hospital and avoided cost for PHS was US$182±32 and US$25,536±4,923 per year; and US$0.55 and US$76.4 per patient/year. The BCR and NB were 0.0, -US$26,105 (95%CI −31,850 − -10,610), -US$27,112 (95%CI −33,160-11,720) for the hospital and; 3.0 (95%CI 1.97-4.94), US$51,048 (95%CI 27,645-75,716) and, 4.6 (95%CI 2.24-10.05), US$91,496 (95%CI 34,700-168,050; p < 0.001) for the PHS, both considering adhered and total interventions, respectively. CONCLUSIONS: The CP service was not directly cost-benefit at the hospital perspective, but it presented savings for forecast cost related to the occurrence of preventable morbidities, measuring a good cost-benefit for the PHS.

Cost-effectiveness analysis is a mandatory strategy for health systems: evidence from a study involving therapies for hepatitis C / Análise de custo-efetividade é uma estratégia essencial para os sistemas de saúde: as evidências de um estudo sobre terapias para hepatite C / El análisis de coste-efectividad es una estrategia esencial para los sistemas de salud: evidencias de un estudio sobre terapias para hepatitis C

Abstract: Cost-effectiveness analysis is essential in health decision making. Several countries use it as synthesis of evidence to incorporate health technologies. The protease inhibitors (PI) boceprevir (BOC) and telaprevir (TVR) are indicated for chronic hepatitis C treatment and were incorporated in guidelines worldwide. Pre-marketing clinical trials showed higher sustained virological response rates in relation to previous therapies, but the incorporation of PIs generated a significant financial impact. The aim of this study was to discuss the relevance of cost-effectiveness analysis through a study that involved the inclusion of PIs in a clinical protocol. The analysis was part of a real-life study that included patients infected with hepatitis C virus genotype 1 treated in a tertiary university hospital in Brazil. Triple therapies (TT) with ribavirin (RBV), peginterferon α-2a (Peg-INF α-2a) and BOC or TVR were compared to dual therapy with RBV and Peg-INF α-2a. Sensitivity analysis of the cost-effectiveness ratio indicated an 88.2% chance of TTs presenting a higher cost per cure. The incremental cost-effectiveness ratios (ICER) exceeded the Brazilian gross domestic product (GDP) per capita by three times in all proposed scenarios. The sensitivity of ICER showed an 88.4% chance of TT not being cost-effective. The impact of PI incorporation was negative and the conduct about this could have been different if a previous cost-effectiveness analysis had been conducted.

Resumo: A análise de custo-efetividade tem sido essencial para a tomada de decisões em saúde. Diversos países utilizam esse tipo de análise como síntese das evidências para incorporar as tecnologias em saúde. Os inibidores de protease (IPs) boceprevir (BOC) e telaprevir (TVR) são indicados para o tratamento da hepatite C crônica e foram incorporados nas diretrizes internacionais. Os ensaios clínicos pré-marketing demonstraram taxas mais altas de resposta virológica sustentada em relação às terapias anteriores, mas a incorporação dos IPs gerou um impacto financeiro significativo. O estudo teve como objetivo discutir a relevância da análise de custo-efetividade, através de um estudo que envolveu a inclusão de IPs em um protocolo clínico. A análise fez parte de um estudo de vida real que incluiu pacientes com infecção pelo vírus da hepatite C, genótipo 1, tratados em um hospital universitário terciário no Brasil. As terapias triplas (TTs) com ribavirina (RBV), peg-interferon α-2a (Peg-INF α-2a) e BOC ou TVR foram comparadas às terapias duplas com RBV e Peg-INF α-2a. A análise de sensibilidade da custo-efetividade indicou odds de 88,2% de TTs apresentarem custo mais elevado por paciente curado. Em todos os cenários propostos, as razões de custo-efetividade incremental (ICERs) superaram em três vezes o produto interno bruto (PIB) per capita brasileiro. A sensibilidade da ICER mostrou probabilidade de 88,4% das TTs não serem custo-efetivas. O impacto da incorporação dos IPs foi negativo, e a conduta teria sido diferente se tivesse sido realizada uma análise prévia de custo-efetividade.

First-wave protease inhibitors for hepatitis C genotype 1 treatment: a real-life experience in Brazilian patients

Abstract INTRODUCTION: Licensed for chronic hepatitis C treatment in 2011, the protease inhibitors (PIs) telaprevir (TVR) and boceprevir (BOC), which have high sustained viral responses (SVR), ushered a new era characterized by the development of direct-action drugs against the hepatitis C virus (HCV). The aim of this study was to analyze the effectiveness and safety of BOC and TVR administered with pegylated interferon and ribavirin and to share the experience of a Brazilian reference center. METHODS: A retrospective descriptive study was conducted in patients with HCV genotype 1 infection who started treatment between July 2013 and December 2015. Data were collected using a computerized system. RESULTS: A total of 115 subjects were included, of which 58 (50.4 %) had liver cirrhosis and 103 (89.6 %) used TVR. The overall SVR rate was 61.7 % (62.1 % for TVR and 58.3 % for BOC). The presence of cirrhosis was associated with a lower SVR rate, whereas patients who relapsed after prior therapy had a greater chance of showing SVR than did non-responders. The incidence of adverse drug reactions (ADRs) was high. Almost all patients (~100 %) presented with hematologic events. Furthermore, treatment had to be discontinued in 15 subjects (13 %) due to severe ADRs. CONCLUSIONS: In conclusion, the SVR rates in our study were lower than those reported in pre-marketing studies but were comparable to real-life data. ADRs, particularly hematological ADRs, were more common compared to those in previous studies and resulted in a high rate of treatment discontinuity.

Cost-effectiveness of insulin analogs from the perspective of the Brazilian public health system

ABSTRACT Human insulin is provided by the Brazilian Public Health System (BPHS) for the treatment of diabetes, however, legal proceedings to acquire insulin analogs have burdened the BPHS health system. The aim of this study was to perform a cost-effectiveness analysis to compare insulin analogs and human insulins. This is a pharmacoeconomic study of cost-effectiveness. The direct medical cost related to insulin extracted from the Ministry of Health drug price list was considered. The clinical results, i.e. reduction in glycated hemoglobin (HbA1c), were extracted by meta-analysis. Different scenarios were structured to measure the uncertainties regarding the costs and reduction in HbA1c. Decision tree was developed for sensitivity of Incremental Cost Effectiveness Ratio (ICER). A total of fifteen scenarios were structured. Given the best-case scenario for the insulin analogs, the insulins aspart, lispro, glargine and detemir showed an ICER of R$ 1,768.59; R$ 3,308.54; R$ 11,718.75 and R$ 2,685.22, respectively. In all scenarios in which the minimum effectiveness was proposed, lispro, glargine and detemir were dominant strategies. Sensitivity analysis showed that the aspart had R$ 3,066.98 [95 % CI: 2339.22; 4418.53] and detemir had R$ 6,163.97 [95% CI: 3919.29; 11401.57] for incremental costs. We concluded there was evidence that the insulin aspart is the most cost-effective.

Adherence and/or discontinuation of imatinib mesylate in patients with chronic myeloid leukemia

ABSTRACT Adherence to imatinib mesylate improves clinical outcomes and promotes a reduction in health expenditure. However, treatment duration and lack of efficacy decrease adherence to pharmacotherapy, resulting in increased mortality associated with Chronic Myeloid Leukemia. This study aimed to evaluate and compare adherence and/or discontinuation of imatinib mesylate in different studies from the literature. An integrative review of original articles published between the years of 2004 and 2014 was performed using the databases PubMed/MEDLINE, Scopus and SciELO. The descriptor "imatinib" was used in two combinations employing the connector AND between terms: "medication adherence'' AND ''imatinib" AND "leukemia'' and ''patient compliance'' AND "imatinib" AND "leukemia". We identified 476 studies, being 14 included in the study. The rates of adherence and discontinuation were diverse, ranging from 19.0 to 97.0% and from 1.8 and 41.0%, respectively, and a high number of longitudinal studies was observed (71.4%). Most studies used questionnaires as an indirect method to assess adherence and factors related to poor adherence were adverse drug reactions, dose changes and unavailability of the medication. Patient education associated with follow up by pharmacists and other health professionals can improve patient adherence and minimize the pharmacotherapy discontinuation.
