RESUMO

Aggregate safety assessment involves evaluation of the totality of safety data to characterize the emerging safety profile of a product. The Drug Information Association-American Statistical Association Interdisciplinary Safety Evaluation scientific working group recently published an approach to developing an Aggregate Safety Assessment Plan (ASAP). Creation of an ASAP facilitates a consistent approach to safety data collection and analysis across studies and minimizes important missing data at the time of regulatory submission. A critical aspect of the ASAP is identification of the Safety Topics of Interest (STOI). The STOI, as defined in the ASAP, comprises adverse events (AEs), which have the potential to impact the benefit: risk profile of a product and typically require specialized data collection or analyses. While there are clear benefits to developing an ASAP for a drug development program, multiple concerns may be encountered with implementation. This article uses the examples of two STOIs to demonstrate the benefits and efficiencies gained with implementation of the ASAP in safety planning as well as in optimally characterizing the emerging safety profile of a product.

RESUMO

Acute kidney injury (AKI) associated with "Triple Whammy" drug therapy consisting of renin-angiotensin system inhibitors, diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs) has been reported. There have been no reports investigating "Triple Whammy" drug therapy and the time to AKI onset using adverse drug events report databases. The aim of this study was to determine the relationship between the time to AKI onset and treatment with "Triple Whammy" drug therapy. We analyzed AKI cases registered in the Japanese Adverse Drug Event Report database. The data were analyzed using the Kaplan-Meier approach, generalized Wilcoxon tests, and Weibull distribution. AKI was reported in 18,415 cases, of which 7,466 cases used Triple Whammy drugs. All combinations of Triple Whammy drugs were associated with significantly higher odds ratios for reporting AKI. In Weibull analysis, AKI onset was early for most combination patterns of Triple Whammy drugs. The Kaplan-Meier approach showed that the treatment duration to AKI onset was much shorter in cases using NSAIDs; median onsets, 8 days for triple combination, 7 days for NSAIDs added to renin-angiotensin system inhibitors, 9 days for NSAIDs added to diuretics, 6 days for diuretics added to NSAIDs, and 9 days for NSAIDs alone. AKI associated with Triple Whammy drugs is likely to occur in the early stages of treatment, especially with concomitant NSAIDs. Patients should be monitored for the occurrence of AKI within the first 2 weeks.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: The aim of this survey, conducted by the Gruppo Italiano per il Trapianto di Midollo Osseo (GITMO), was to evaluate the involvement of pharmacists in the haematopoietic stem cell transplant (HSCT) program in Italian adult and paediatric centres. METHODS: A 63-item online questionnaire was developed and sent to the Italian Transplant Programs on behalf of GITMO. RESULTS AND DISCUSSION: Overall, 54.7% of the Italian HSCT centres participated in the survey (88.5% adult, 7.7% paediatric, 3.8% mixed), of which 50% were in public hospitals and 50% affiliated with public universities. Just over 80% declared that a pharmacist is involved in the HSCT centre, and 86.5% reported the presence of a documentation system to signal of adverse events, accessible by physicians, nurses and pharmacists in 57.7%. Chemotherapy drugs were centralized in the pharmacy in 98.1% of HSCT centres, while parenteral nutrition was centralized in 55.8%. The use of off-label drugs was authorized by an internal committee and by the regional health authorities in 88.5% of the centres. On univariate analysis, few statistically significant differences were found on response frequencies between public hospitals and university centres or between HSCT centres performing only autologous stem cell transplantation versus other centres performing autologous and allogeneic stem cell transplantation. WHAT IS NEW AND CONCLUSION: This survey suggests that there is good collaboration between pharmacists and physicians and nurses in Italian HSCT transplantation centres. The enhancement of pharmacists dedicated to HSCT programs could improve some problems, for example, the centralization of parenteral nutrition.

RESUMO

The COVID-19 pandemic presents several challenges to the organisation and workflow of pharmacovigilance centres as a result of the massive increase in reports, the need for quick detection, processing and reporting of safety issues and the management of these within the context of lack of complete information on the disease. Pharmacovigilance centres permanently monitor the safety profile of medicines, ensuring risk management to evaluate the benefit-risk relationship. However, traditional pharmacovigilance approaches of spontaneous reporting, are not suitable in the context of a pandemic; the scientific community and regulators need information on a near real-time point. The aim of this commentary is to suggest six interrelated multidimensional guiding axes for drug safety management by pharmacovigilance centres during the COVID-19 pandemic. This working plan can increase knowledge on COVID-19 and associated therapeutic approaches, support decisions by the regulatory authorities, oppose fake news and promote more efficient public health protection.

RESUMO

PURPOSE: Reporting of adverse drug reactions (ADRs) by patients is essential for a comprehensive risk-benefit evaluation of drugs after marketing, but only few data are available regarding patient-centred web-based ADR reporting systems. Hence, we aimed to analyze ADRs reported by patients with a particular emphasis on novel drugs and serious ADRs not yet labelled in the respective summary of product characteristics (SPC). METHODS: All ADR reports received by a web-based, patient-centred platform ( www.nebenwirkungen.de ) between April 1, 2019, and September 1, 2020, were descriptively analyzed. ADRs and drugs were coded automatically according to MedDRA and ATC classification system. SPC labelling of reported ADRs for novel drugs marketed since 2015 was checked manually. RESULTS: In total, 13,515 patient reports including 29,529 ADRs were received during the study period (serious ADRs [SADRs] n = 1,318; 4.5%). Women were affected in more than two-thirds of ADR reports. The most common patient-reported ADRs were nausea, dizziness and headache, whereas arrhythmia, intestinal obstruction and erectile dysfunction were the most frequent SADRs. Ciprofloxacin, levothyroxine and venlafaxine were the compounds most frequently suspected for causing both ADRs and SADRs. Regarding novel compounds, 289 reports including 739 ADRs were received (mainly fatigue, headache and myalgia). Three hundred thirty-one (44.8%) out of those ADRs were not yet labelled in the respective SPC, whereof twelve were SADRs. CONCLUSION: The majority of patient-reported ADRs were non-serious. However, a relevant number of non-labelled even serious ADRs was reported for novel compounds by patients. Despite well-known limitations of patient-reported ADRs, this web-based ADR reporting system contributes to the identification of new ADRs and thus can help to improve patients' safety complementing other pharmacovigilance instruments.

RESUMO

Adverse drug reaction (ADR) reporting is a major component of drug safety monitoring; its input will, however, only be optimized if systems can manage to deal with its tremendous flow of information, based primarily on unstructured text fields. The aim of this study was to develop an automated system allowing to code ADRs from patient reports. Our system was based on a knowledge base about drugs, enriched by supervised machine learning (ML) models trained on patients reporting data. To train our models, we selected all cases of ADRs reported by patients to a French Pharmacovigilance Centre through a national web-portal between March 2017 and March 2019 (n = 2,058 reports). We tested both conventional ML models and deep-learning models. We performed an external validation using a dataset constituted of a random sample of ADRs reported to the Marseille Pharmacovigilance Centre over the same period (n = 187). Here, we show that regarding area under the curve (AUC) and F-measure, the best model to identify ADRs was gradient boosting trees (LGBM), with an AUC of 0.93 (0.92-0.94) and F-measure of 0.72 (0.68-0.75). This model was run for external validation showing an AUC of 0.91 and a F-measure of 0.58. We evaluated an artificial intelligence pipeline that was found able to learn how to identify correctly ADRs from unstructured data. This result allowed us to start a new study using more data to further improve our performance and offer a tool that is useful in practice to efficiently manage drug safety information.

RESUMO

Adverse drug reactions (ADRs) for all drugs in Europe are described in the legally approved Summary of Product Characteristics (SmPC). An overview of all ADRs of the patients' drug list can support healthcare staff to link patient symptoms to possible ADRs. We review the possibilities and challenges to extract ADR information from SmPCs or American Structured Product Labels and present the development of our semi-automated procedure for extraction of ADRs from the tabulated section in the SmPCs to create a database, named Bikt, which is regularly updated and used at point of care in Sweden. The existence of five major table formats for ADRs used in the SmPCs required the development of different parsing scripts. Manual checks for correctness for all content have to be performed. The quality of extraction was investigated for all SmPCs by measuring precision, recall and F1 scores and compared with other methods published. We conclude that it is possible to semi-automatically extract ADR information from SmPCs. However, clear technical and content guidelines and standards for ADR tables and terms from drug registration authorities would lead to improved extraction and usability of ADR information at point of care.

RESUMO

The current COVID-19 pandemic is an exceptional health situation including for drug use. As there was no known effective drug for COVID-19 at the beginning of the pandemic, different candidates were proposed. In this short article, we present the French public pharmacovigilance activities during this health crisis. Although COVID-19 is a confounding factor per se, owing to its potential for multi-organ damage including the heart and kidney, the quality of the transmitted data in adverse drug reaction reports, the timeliness of feedback from clinicians, and the real-time pharmacological and medical analysis by the French network of the regional pharmacovigilance centers made it possible to swiftly identify relevant safety signals. The French National Agency of Medicine was thus able to validate the data and convey their findings very early. This decentralized organization based on medical and pharmacological evaluation of case reports has proven to be efficient and responsive in this unique and challenging healthcare emergency.

RESUMO

Chagas disease (CD) and tuberculosis (TB) are important health problems in Bolivia. Current treatments for both infections require a long period of time, and adverse drug reactions (ADRs) are frequent. This study aims to strengthen the Bolivian pharmacovigilance system, focusing on CD and TB. A situation analysis of pharmacovigilance in the Department of Cochabamba was performed. The use of a new local case report form (CRF) was implemented, together with the CRF established by the Unidad de Medicamentos y Tecnología en Salud (UNIMED), in several healthcare centers. Training and follow-up on drug safety monitoring and ADR reporting was provided to all health professionals involved in CD and TB treatment. A comparative analysis of the reported ADRs using the CRF provided by UNIMED, the new CRF proposal, and medical records, was also performed. Our results showed that out of all patients starting treatment for CD, 37.9% suffered ADRs according to the medical records, and 25.3% of them were classified as moderate/severe (MS). Only 47.4% of MS ADRs were reported to UNIMED. Regarding TB treatment, 9.9% of all patients suffered ADRs, 44% of them were classified as MS, and 75% of MS ADRs were reported to UNIMED. These findings show that the reinforcement of the Bolivian pharmacovigilance system is an ambitious project that should involve a long-term perspective and the engagement of national health workers and other stakeholders at all levels. Continuity and perseverance are essential to achieve a solid ADR reporting system, improving patient safety, drug efficacy and adherence to treatment.

RESUMO

PURPOSE: Underreporting is the major limitation of a voluntary adverse drug reaction (ADR) reporting system. Many studies have assessed the effectiveness of different interventions designed to improve ADR reporting. The aim of this study was to systematically map interventions and strategies to improve ADR reporting among health care professionals. METHODS: The six-stage methodological framework of Arksey and O'Malley was used to conduct this scoping review. Ovid MEDLINE, EMBASE, All EBM, and Web of Science were systematically searched from 1999 to February 2019, and the reference lists of the included papers were also searched for gray literature to identify any interventions and strategies that aimed to increase ADR reporting. Two reviewers screened the papers for eligibility based on the inclusion criteria and extracted their key data and analyzed them descriptively. RESULTS: Ninety out of 14 501 papers met the selection criteria. Using computerized registration and active surveillance can increase ADR reporting significantly. Educational interventions performed individually or combined with sending reminders and/or feedback, awards, and providing easier reporting channels can improve ADR reporting over a short to medium term. Multiple interventions may have more impact than single-component interventions. CONCLUSION: Multiple interventions could cause a greater increase in ADR reporting rates than single interventions. Although educational interventions appear to be effective, few studies have reviewed their long-term effects to ascertain whether the improvements are sustained over time. Studies with a better methodological quality are required on this subject.

RESUMO

PURPOSES: The aim of the pharmacovigilance (PV) process is to bring together all the much-needed information about various aspects of product safety or, in particular, the safety and vigilance of drugs as pharmaceutical products. This study aimed to investigate and provide an overview on the current situation and activities of the national PV centers in Arab countries. METHODS: A cross sectional study was conducted between March and May in 2018. The current survey was adopted and modified from a study that used the questionnaire designed by the World Health Organization Collaborating Centre for International Drug Monitoring. The national PV centers of 22 Arab countries were invited to participate in this study. Descriptive analyses were conducted utilizing the analysis services provided by SurveyMonkey. RESULTS: In total of, 15 countries responded to our invitation (response rate: 68%). Most Arab countries started their PV program in the last decade, with Palestine implementing its program in 2017. Among the respondents, nine (60%) were members of the WHO International Drug Monitoring Program and were all users of the software provided by the WHO Uppsala Monitoring Center (VigiFlow or VigiBase), except Sudan. In 2017, a total of 27 502 reports were received by the centers in the studied countries, ranging from three reports received in Lebanon to a total of 7362 reports received by the national program of Algeria. CONCLUSIONS: An improvement was noticed among the national PV programs in the Arab countries. However, a considerable difference still exists among the countries in terms of the implementation and practice of PV.

RESUMO

OBJECTIVES: To introduce the methodology of the ALCAPONE project. BACKGROUND: The French National Healthcare System Database (SNDS), covering 99% of the French population, provides a potentially valuable opportunity for drug safety alert generation. ALCAPONE aimed to assess empirically in the SNDS case-based designs for alert generation related to four health outcomes of interest. METHODS: ALCAPONE used a reference set adapted from observational medical outcomes partnership (OMOP) and Exploring and Understanding Adverse Drug Reactions (EU-ADR) project, with four outcomes-acute liver injury (ALI), myocardial infarction (MI), acute kidney injury (AKI), and upper gastrointestinal bleeding (UGIB)-and positive and negative drug controls. ALCAPONE consisted of four main phases: (1) data preparation to fit the OMOP Common Data Model and select the drug controls; (2) detection of the selected controls via three case-based designs: case-population, case-control, and self-controlled case series, including design variants (varying risk window, adjustment strategy, etc.); (3) comparison of design variant performance (area under the ROC curve, mean square error, etc.); and (4) selection of the optimal design variants and their calibration for each outcome. RESULTS: Over 2009-2014, 5225 cases of ALI, 354 109 MI, 12 633 AKI, and 156 057 UGIB were identified using specific definitions. The number of detectable drugs ranged from 61 for MI to 25 for ALI. Design variants generated more than 50 000 points estimates. Results by outcome will be published in forthcoming papers. CONCLUSIONS: ALCAPONE has shown the interest of the empirical assessment of pharmacoepidemiological approaches for drug safety alert generation and may encourage other researchers to do the same in other databases.

RESUMO

BACKGROUND: Efficiency and accuracy for signal detection and evaluation activities are integral components of routine Pharmacovigilance (PV) practices. However, an Individual Case Safety Report (ICSR) may consist of a variety of confounders such as Concomitant Medications (CM), Past Medical History (PMH), and concurrent medical conditions that influence a safety officer's evaluation of a potential Adverse Event (AE). Limited pharmacovigilance systems are currently available as a tool designed to enhance the efficiency and accuracy of signal detection and management. OBJECTIVE: To introduce a systemic approach to make critical safety information readily available for users in order to discern possible interferences from CM and make informed decisions on the signal evaluation process - saving time while improving quality. METHODS: Oracle Empirica Signal software was utilized to extract cases with CM that are Known Implicating Medications (KIM) for each AE according to public regulatory information from drug labels - FDA Structured Product Labeling (SPL) or EMA Summary of Product Characteristics (SPC). SAS Enterprise Guide was used to further process the data generated from Oracle Empirica Signal software. RESULTS: For any target drug being evaluated for safety purposes, a KIM reference table can be generated, which summarizes all potential causality contributions from CMs. CONCLUSION: In addition to providing standalone KIM table as reference, adoption of this concept and automation may also be fully integrated into commercial signal detection and management software packages for easy use and accessibility and may even lead to reduced False Positive rate in signal detection within the PV space.

RESUMO

INTRODUCTION: The Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) and VigiBase® are two established databases for safety monitoring of medicinal products, recently complemented with the EudraVigilance Data Analysis System (EVDAS). OBJECTIVE: Signals of disproportionate reporting (SDRs) can characterize the reporting profile of a drug, accounting for the distribution of all drugs and all events in the database. This study aims to quantify the redundancy among the three databases when characterized by two disproportionality-based analyses (DPA). METHODS: SDRs for 100 selected products were identified with two sets of thresholds (standard EudraVigilance SDR criteria for all vs Bayesian approach for FAERS and VigiBase®). Per product and database, the presence or absence of SDRs was determined and compared. Adverse events were considered at three levels: MedDRA® Preferred Term (PT), High Level Term (HLT), and HLT combined with Standardized MedDRA® Query (SMQ). Redundancy was measured in terms of recall (SDRs in EVDAS divided by SDRs from any database) and overlap (SDRs in EVDAS and at least one other database, divided by SDRs in EVDAS). Covariates with potential impact on results were explored with linear regression models. RESULTS: The median overlap between EVDAS and FAERS or VigiBase® was 85.0% at the PT level, 94.5% at the HLT level, and 97.7% at the HLT or SMQ level. The corresponding median recall of signals in EVDAS as a percentage of all signals generated in all three databases was 59.4%, 74.1%, and 87.9% at the PT, HLT, and HLT or SMQ levels, respectively. The overlap difference is partially explained by the relative number of EU cases in EudraVigilance and the ratio of EVDAS cases and FAERS cases, presumably due to differences in marketing authorizations, or market penetration in different regions. Products with few cases in EVDAS (< 1500) also display limited recall of signals relative to FAERs/VigiBase®. Time-on-market does not predict signal redundancy between the three databases. The choice of the DPA has an expected but somewhat small effect on redundancy. CONCLUSIONS: Organizations typically consider regulatory expectations, operating performance (e.g., positive predictive value), and procedural complexity when selecting databases for signal management. As SDRs can be seen as a proxy of general reporting characteristics identifiable in a systematic screening process, our results indicate that, for most products, these characteristics are largely similar in each of the databases.

RESUMO

BACKGROUND: Pharmacovigilance is an important aspect of clinical practice; however, there is limited evidence that it exists as a theme in medical education curricula. OBJECTIVE: We developed and used a Basic Research Skill Special Study Module to introduce pharmacovigilance to medical students in the early years of their programme. METHODS: Students completing year one or two of the Faculty of Medical Sciences, Bachelor of Medicine, Bachelor of Surgery programme at The University of the West Indies, Jamaica participated in the four week experience from May 16th to June 12th 2019 to complete structured content sessions and self-directed activity. Sessions focused on the importance of pharmacovigilance and guided steps to complete a secondary data research project on an adverse reaction reported for a drug of personal interest. The final output was a poster mini-symposium at which each student held a five minute oral presentation. Posters were assessed for compliance with content guidelines, quality and presentation. RESULTS: Ten students participated in this experience and nine students produced posters of greater than 80% compliance with the content guidelines that were provided. The points awarded also reflected high scores for the required elements, relevant graphics, attractiveness/neatness and oral presentation. Students expressed overall satisfaction with the learning experience of the module. CONCLUSION: Moving forward, the authors will continue using this innovative active learning methodology to increase student exposure to pharmacovigilance, conducting and sharing research. Quantitative outcome assessment tools will be developed and long term goals will focus on its utility in curriculum improvement.

RESUMO

BACKGROUND: TransCelerate's Intelligent Automation Opportunities (IAO) in Pharmacovigilance initiative has been working to evaluate various pharmacovigilance processes to facilitate systematic innovation with intelligent automation across the entire area. The individual case safety report (ICSR) process was the first process selected for evaluation because of its resource-intensive nature, risk of errors, and operational inefficiencies. OBJECTIVES: TransCelerate's IAO in Pharmacovigilance initiative initially worked to articulate an end-to-end ICSR process that would generically apply to various pharmacovigilance organizations, despite organizational variations in specific ICSR process steps. This paper aims to address the need for a systematic review framework for automation of the ICSR process from the value, impact, perceived risk, and opportunity point of view. METHODS: The generic ICSR process, which starts with receipt of an adverse event report, was grouped into three process blocks: case intake, case processing, and case reporting. Each of these was then further detailed in individual process steps. A total of 19 TransCelerate member companies were invited to complete a survey designed to facilitate understanding of automation opportunities across the ICSR process. Heat maps of the current level of effort, expected benefit of automation, and perceived risk of automation were compiled from responses to identify intelligent automation opportunities for specific ICSR process steps. Relevant experts on the TransCelerate evaluation team analyzed and interpreted the anonymized and aggregated results. RESULTS: In total, 15 TransCelerate member companies responded to the survey and indicated that ICSR process steps with current high effort, expected high automation benefit, low or manageable automation risk, and low levels of current automation present the best opportunities for future automation. Such steps include language translations, case verification, in-line quality control, prioritization/triage, data entry, alerts for cases of interest, workflow management, and monitoring. Some steps (e.g., submission) have been automated for a number of years and appear on the heat map as having low potential for further automation. The survey responses implied that, despite successful use of intelligent automation technologies in other areas, adoption within pharmacovigilance and the ICSR process in particular remains limited. The perceived high risk to patient safety is expected to decrease with additional successful applications in pharmacovigilance. CONCLUSIONS: Our results highlight the areas of greatest opportunity for intelligent automation based on the potential benefits of applying intelligent automation and the perceived risks associated with each ICSR process step. Responding TransCelerate member companies already automate many steps to varying degrees. However, a significant opportunity remains for automation to penetrate further. Additionally, the pharmacovigilance industry culture needs to change in order to reduce the perceived risk of automation and to encourage a more progressive approach to intelligent automation. Increased automation is crucial to empower agile and efficient pharmacovigilance.

RESUMO

INTRODUCTION: The increased access to medicinal products in Africa is not well-matched with the pharmacovigilance capacity to monitor drug safety. The objective of this study was to assess the functionality and identify the strengths and limitations of the national pharmacovigilance systems in Ethiopia, Kenya, Rwanda, and Tanzania, and compare these systems. METHODS: Legal and statutory documents governing the pharmacovigilance systems of each participating country were examined by assessors prior to on-site review. The staff of the pharmacovigilance unit of the National Medicines Regulatory Authorities (NMRAs) were interviewed using the East African Community Harmonized Pharmacovigilance Indicators tool, supplemented with indicators from the World Health Organization (WHO) Global Benchmarking Tool. Responses were recorded, and data were analyzed. RESULTS: The pharmacovigilance systems were supported by law and regulations in line with international standards. Standard operating procedures for receiving, processing, and communicating suspected adverse event reports were in place, but reporting of suspected medicine-related harm from stakeholders was inadequate in all countries. The number of Individual Case Safety Reports (ICSRs) received by NMRAs in Kenya, Ethiopia, and Tanzania (mainland) were 35.0, 6.7, and 4.1 per million inhabitants, respectively, in the last calendar year. At the time of assessment, Rwanda did not have an operational system. Overall, ≤ 1% of the total number of health facilities per country submitted ICSRs. Only Kenya and Tanzania had a designated budget for pharmacovigilance activities and an electronic ICSR reporting system. The national pharmacovigilance systems in all four countries did not have access to data on drug utilization. CONCLUSIONS: The national pharmacovigilance systems in the four East African countries have policy and legal frameworks defined by law and regulation to conduct pharmacovigilance activities. However, the four national pharmacovigilance systems are at different levels of capacity and performance with respect to conducting pharmacovigilance activities. Targeted interventions are needed to strengthen the pharmacovigilance systems to enable evidence-based decision making for patient safety.

RESUMO

Adverse event (AE) reporting is a key component of patient safety and physicians are known to underreport. The authors hypothesized that integrating AE reporting into a mobile application used in daily physician workflow would increase physician reporting of AEs. After integrating AE reporting into a free-text mobile application used for daily workflow, the change in AE reporting by physicians was analyzed using Mann-Whitney U tests. AE reporting by physicians increased more than 37-fold (21 to 806; U = 7.5, P < .0001). AE reporting by physicians as a proportion of all AE reports received increased 120-fold (from 0.1% to 12% of all reports, U = 10, P < .0001). Integrating AE reporting into a free-text mobile application used in daily physician workflow markedly increased their reporting of AEs. This approach shifted time burden from physicians to quality officers. Implementation should be coupled with physician education about identifying AEs and content to include in reports.

RESUMO

OBJETIVO: La justificación del estudio fue evaluar el grado de conocimiento de los farmacéuticos españoles en el ámbito de la Farmacovigilancia, su grado de notificación de Reacciones Adversas a Medicamentos (RAM) y su necesidad de formación, estableciendo las diferencias entre los farmacéuticos de farmacia comunitaria (FC) y los de farmacia hospitalaria (FH). MÉTODOS: Se diseñó un cuestionario con doce preguntas sobre Farmacovigilancia. La distribución y recogida de los cuestionarios se realizo vía online con la colaboración de los Colegios Oficiales de Farmacéuticos y la Sociedad Española de Farmacia Hospitalaria, durante el periodo de noviembre de 2018 a junio de 2019.La población diana fueron los farmacéuticos colegiados o pertenecientes a la Sociedad Española de Farmacia Hospitalaria. Los resultados fueron procesados mediante un análisis descriptivo y analítico. Las variables cualitativas se presentaron con su distribución de frecuencias y las cuantitativas con su media y desviación estándar. RESULTADOS: El 99% de los FH afirmaron haber tenido constancia de una RAM y el 96,9% de ellos la notificaron. El 73,5% de los FC declararon que tuvieron constancia de una RAM pero sólo el 48,7% confirmaron que la notificaran. En general, los farmacéuticos encuestados estaban de acuerdo en la importancia de la Farmacovigilancia, y opinaban que se podría mejorar la calidad de los tratamientos y se ahorraría en el sistema de salud español si se aplicara más la Farmacovigilancia. CONCLUSIONES: Nuestros resultados indican que los FH notifican más una RAM que los FC. También son los FH los que conocen mejor las obligaciones que tienen con Farmacovigilancia. Los farmacéuticos encuestados piensan que el desarrollo de actuaciones en Farmacovigilancia, aumentaría la adhesión de los profesionales a la notificación e implicaría mejoras en la calidad de los tratamientos, el uso racional de los medicamentos y la seguridad del paciente


OBJECTIVE: The justification of the study was to assess the degree of knowledge of Spanish pharmacists in the field of Pharmacovigilance, their degree of notification of adverse drug reactions and their need for training, establishing the differences between community pharmacy pharmacist and those of hospital pharmacy. METHODS: A questionnaire with twelve questions on Pharmacovigilance was designed. The distribution and collection of the questionnaires were carried out via online in collaboration with the Official Colleges of Pharmacists and the Spanish Society of Hospital Pharmacy during the period from November 2018 to June 2019. The target population were the pharmacists registered or belonging to the Spanish Society of Hospital Pharmacy. The results were processed using a descriptive and analytical analysis. The qualitative variables were presented with their frequency distribution and the quantitative with their mean and standard deviation. RESULTS: 99% of hospital pharmacists said they had evidence of suspected adverse reactions and 96.9% of them ever reported. 73.5% of community pharmacists stated that they had knowledge of suspected adverse reactions but only 48.7% confirmed that they notified them. In general, the pharmacists surveyed agreed on the importance of Pharmacovigilance and believed that the quality of treatments could be improved and the Spanish health system would be saved if Pharmacovigilance was applied more. CONCLUSIONS: Our results indicated that hospital pharmacists report much more adverse drug reactions than community pharmacist does. It also hospital pharmacists who know best the obligations they have with Pharmacovigilance. The surveyed pharmacists thought that the development of actions in Pharmacovigilance would increase the adherence of pharmaceutical professionals to the notification and would imply improvements in the quality of treatments, the rational use of medications and patient safety
