Active involvement of the general public in pharmacovigilance
The importance of direct patient reporting has been highlighted by recent European legislation on
pharmacovigilance, and in addition, there is also an increasing attention worldwide for this subject.
In Europe, the legislation directs member states to take all appropriate measures to encourage
patients to report suspected adverse drug reactions (ADR) to the relevant national authorities.
The introduction of patient reporting in pharmacovigilance indicates a change in attitude in which
patient reporting is valued due to their potential to contribute useful information on drug safety.
The aim of this project is to give a better understanding of the role of patients in pharmacovigilance
systems. The chosen approach during this project intended to lead to a better understanding of
the awareness and perception of the risk involved with medicine use and how patients and
healthcare professionals can contribute to optimize the current pharmacovigilance system. For
the purpose of this study, the project was divided in several parts, for which specific objectives
were designed and described below, together with main results of the thesis.
The first study described in Chapter 2 discusses the experiences of patient reporting to
pharmacovigilance in Portugal and quantifies consumers motivation for reporting ADRs,
investigating patient opinions about reporting with a quantitative analysis in a large group of
consumers. The objective was to describe the attitudes and knowledge of the general public regarding spontaneous reporting and the reasons and opinions that can influence consumers adverse drug reaction underreporting. The study reveals that consumers are more likely to do
spontaneous report about severe reactions or if they are worried about the symptoms. Also, more
altruistic motives as the contribution to research and knowledge, the contribution to improvement
of drugs and prevent harm to other people are seen as motives to report ADRs by patients. These
motives can be classified in reporting for oneself (severity, worried, problems), reporting for others
(share experiences, preventing harm, feeling responsible) or reporting for improvement (research
and knowledge, patient information leaflet). It appeared that multiple patient characteristics
(gender, age and level of education) had an effect on the motives of patients to report their ADR.
In Chapter 3 were described the attitudes toward patient reporting systems, and progress toward
implementing such systems among national competent authorities participating in the World
Health Organization Programme for International Drug Monitoring. The study shows that most
countries accept ADR reports from patients by an official reporting system designed for patients
or through the existing system for Healthcare Professionals (HCPs). The main reasons for not
having a Patient Reporting System (PRS) are financial restraints and a lack of
information/education of patients. Attitudes toward a PRS are positive, but some countries fear
181
that they will not be able to handle an increase in reports. Most countries accept ADR reports
from the general public.
The lack of resources/budget and the lack of information/education for patients are highlighted as
the major obstacles to the implementation of PRS.
Chapter 4 focused on patient organizations role to promote patient reporting. In Chapter 4.1, it
was studied the role of European patient organizations with the objective of understand the role
of European patient organizations as stakeholders to optimize patient involvement in
pharmacovigilance. There is a wide range of interest in drug safety issues among patient
organizations, which appear to have an important role in encouraging patients to talk with their
doctors/pharmacists about ADRs experienced, or to help him/her report the ADRs to the
pharmacovigilance systems. A lack of resources, budget, and support from National Competent
Authorities (NCAs) are seen as the main barriers to being involved in pharmacovigilance. On the
other hand, an important part of the organizations appears to not have any activities or
involvement related to pharmacovigilance. Bringing pharmacovigilance stakeholders and patient
organizations together could create a more optimal patient reporting culture. Members of a patient
organization showed more positive opinions related to pharmacovigilance. They would like to
have more information about ADRs related to their medication and a higher intention to have
information on how to report when compared to other patients.
The other study in Chapter 4 described
medicines and attitudes and opinions regarding pharmacovigilance in people with diabetes. The
study explored the impact of the patient reports being followed by a patient diabetes association.
The objective was to assess risk perception of developing adverse drug reactions and knowledge,
attitudes and opinions regarding pharmacovigilance in patients with diabetes and to investigate
whether being a member of a patient organization for diabetes had an effect on these factors.
Patients followed in a diabetes patient association presented a higher score of risk perception,
experiences using the medicines, but also by the information received from the patient
organization. Being a member of a patient organization seems to have an important role in
increasing risk perception since they presented the highest risk perception scores for medicines
related to their disease. Those patients affirmed that their doctor explained the possible ADRs of
their medication and they have higher intention to report ADRs in the future if they are serious or
unexpected. Patient organizations are well positioned to be a source where patients can obtain
reliable information, changing their attitudes and perceptions about the disease and drug
treatments.
An additional chapter was provided, related with HCPs role as active agents to improve the
involvement of patients in pharmacovigilance. Chapter 5.1 objective was to describe the attitudes
and knowledge of different community pharmacy professional groups regarding the spontaneous
reporting of adverse drug reactions to identify the factors that can influence adverse drug reaction
under-reporting. Despite HCPs knowledge of the pharmacovigilance system, only a small
182
percentage of Community pharmacy professionals had reported ADRs, and approximately half
did not usually encourage consumers to report possible ADRs.
In Chapter 5.2, the objective was to evaluate community pharmacy professionals as role players
. Reporting
of ADRs is fundamental to pharmacovigilance, and consumer reporting is a significant
contribution to creating useful information on drug safety. Community pharmacy professionals
can play a major role in pharmacovigilance by reporting ADRs directly or encouraging consumers
to report them. Measures to overcome under-reporting as encouraging HCPs and consumers to
play an active role in pharmacovigilance, namely continuous education and training should be
incorporated to increase the level of risk perception and encourage a better attitude about
reporting for both HCPs and consumers.
Chapter 6 presents a general discussion about the role of general public in pharmacovigilance,
providing recommendations that arose from the results with different points of view of patient
participation in pharmacovigilance (national competent authorities, HCPs, patient organizations
and patients themselves).
In conclusion, this thesis has focused on an overview of the participation of different stakeholders
in pharmacovigilance, including HCPs, NCAs, Patient Organizations and patients themselves.
Further research and developments for pharmacovigilance systems and for patients themselves
arose from the results provided.Recientemente, la legislación europea sobre farmacovigilancia ha resaltado la importancia de la
participación de los ciudadanos en la notificación espontánea de sospechas de reacciones
adversas (RAMs), siendo este asunto objeto de atención creciente en todo el mundo. En Europa,
la legislación establece que los Estados miembros deben tomar las medidas apropiadas para
alentar a los pacientes a notificar las de sospechas de RAMs a las autoridades nacionales
competentes. La introducción de esta posibildad, indica un cambio de actitud en el que se valora
el informe del paciente debido a su potencial para aportar información útil sobre la seguridad de
los medicamentos.
El objetivo de esta tesis es comprender mejor el papel de los pacientes en los sistemas de
farmacovigilancia. El enfoque elegido pretende describir la conciencia y la percepción del riesgo
por parte de los pacientes en relación con el uso de medicamentos y cómo tanto ellos, como los
profesionales de la salud (PS) pueden contribuir a optimizar el sistema actual de
farmacovigilancia. Con este propósito, la tesis se dividió en varias partes, cuyos objetivos
específicos y principales resultados, se describen a continuación. En el primer estudio descrito en el Capítulo 2, se discuten las experiencias de la notificacion
ciudadana al sistema de farmacovigilancia en Portugal y cuantifica la motivación de los
consumidores, investigando sus opiniones a través de un análisis cuantitativo llevado a cabo en
un gran grupo de usuarios. El objetivo de este estudio es describir las actitudes y el conocimiento
de los ciudadanos en general con respecto a las notificaciones espontáneas y las razones y
opiniones que pueden influir en la escasa notificación de RAMs por su parte. El estudio revela
que es más probable la notificación espontánea por parte de los ciudadanos, cuando se trate de
reacciones graves o si existiera preocupación por los síntomas generados por la RAM. Además,
otros motivos más altruistas como la contribución a la investigación y al conocimiento, la
contribución a la mejora de los fármacos y la prevención del daño en otras personas, también
fueron considerados por los pacientes como motivos para notificar RAM. Estas motivaciones
pueden clasificarse en: notificar para uno mismo (gravedad, preocupación, problemas), para
otros (compartir experiencias, prevenir daños, sentirse responsable) o para la mejora
(investigación y conocimiento, hoja de información para el paciente). Asimismo, diferentes
características del paciente como género, edad y nivel de educación, tenían influencia en sus
motivos para notificar sus RAMs.
El Capítulo 3 describe las actitudes de las autoridades nacionales de los participantes en el
Programa de la Organización Mundial de la Salud de Vigilancia Farmacéutica Internacional
acerca de la notificación ciudadana de sospechas de RAM y del progreso en su implementación.
187
El estudio muestra que la mayoría de los países aceptan notificaciones de sospechas de RAMs
de los ciudadanos mediante un sistema oficial diseñado especialmente para ellos, o bien
mediante el sistema existente para PS. Las principales razones para no disponer de un Sistema
de Notificación de sospechas de RAM para Ciudadanos (SNRC) son las restricciones
económicas y la falta de información / educación de los pacientes. Las actitudes acerca de los
SNRC son positivas, aunque algunos países temen no poder manejar un aumento de las
notificaciones de sospechas. La falta de recursos y la falta de información/educación de los
pacientes se destacan como los principales obstáculos para la implementación del SNRC.
El Capítulo 4 se centró en el papel de las organizaciones de pacientes para promover la
notificación. En el Capítulo 4.1 se estudió el papel de las organizaciones europeas de pacientes
como partes interesadas en optimizar la participación del paciente en la farmacovigilancia. Existe
un amplio interés en los problemas de seguridad de los medicamentos entre las organizaciones
de pacientes. Estas organizaciones parecen tener un papel importante alentando a los pacientes
a hablar con sus médicos / farmacéuticos sobre las RAM experimentadas, o ayudándolo a
informar las sospechas de RAM a los sistemas de farmacovigilancia. La falta de recursos y apoyo
de las Autoridades Nacionales Competentes se consideran las principales barreras para
participar en la farmacovigilancia. Por otro lado, una parte importante de las organizaciones
parece no tener ninguna actividad relacionada con la farmacovigilancia. Reunir a las partes
interesadas en farmacovigilancia con las organizaciones de pacientes podría crear una cultura
de notificaciones de sospechas por los pacientes optimizada. De un estudio realizado en una
organización de pacientes de pacientes diabéticos (Capítulo 4.2) sabemos que sus miembros
mostraron opiniones positivas relacionadas con la farmacovigilancia. En general, a los pacientes
asociados les gustaría tener más información sobre las RAMs de sus medicación y tenían mayor
interés en disponer de información sobre cómo notificar que los pacientes diabéticos que no
formaban parte de la asociación. El capítulo 5.1 se centró en el papel de los PS como agentes activos para mejorar la participación
de los pacientes en la farmacovigilancia. El objetivo del Capítulo 5.1 era describir las actitudes y
el conocimiento de los diferentes grupos profesionales de Farmacias Comunitarias con respecto
a la notificación espontánea de RAM para identificar los factores que puedan influir en la falta de
notificación. A pesar de que los PS conocen el sistema de farmacovigilancia, solo un pequeño
porcentaje de los profesionales de Farmacia Comunitaria ha informado de RAMs, y
aproximadamente la mitad no suele alentar a los ciudadanos a informar sospechas de RAMs.
En el Capítulo 5.2, el objetivo fue evaluar a los profesionales de Farmacia Comunitaria como
actores en la mejora de la participación de los ciudadanos en la farmacovigilancia y describir sus
actitudes en relación con el sistema de farmacovigilancia y la notificación ciudadana de
sospechas de RAMs. Las notificaciones de RAMs son fundamentales para la farmacovigilancia,
y los informes de los ciudadanos son una contribución significativa a la creación de información
útil sobre la seguridad de los medicamentos. Los profesionales de la Farmacia Comunitaria
pueden desempeñar un papel importante en la farmacovigilancia notificando directamente o
188
alentando a los ciudadanos. Se deben implementar medidas como estrategias de educación y
capacitación continua para superar la falta de información de los ciudadanos y alentar a los
profesionales sanitarios a desempeñar un papel activo en la farmacovigilancia, mejorando su
nivel de percepción de riesgo y promoviendo una mejor actitud.
El Capítulo 6 presenta una discusión general sobre el papel del ciudadano en la
farmacovigilancia, brindando recomendaciones surgidas de los resultados de los estudios sobre
los diferentes puntos de vista (autoridades nacionales competentes, profesionales sanitarios,
organizaciones de pacientes y los propios pacientes) acerca de la participación del paciente en
la farmacovigilancia.
En conclusión, esta tesis se ha centrado en una visión general de la participación de diferentes
partes interesadas en la farmacovigilancia, incluidos los PS, las autoridades nacionales
competentes, las organizaciones de pacientes y los propios pacientes. De los resultados
proporcionados, surge la necesidad de un desarrollo adicional de medidas dirigidas a los PS,
pacientes y a los propios sistemas de farmacovigilancia para mejorar la participación de los
ciudadanos en los sistemas de farmacovigilancia
Are patients ready to take part in pharmacovigilance system : a Portuguese preliminary study concerning ADR reporting
Background: New Pharmacovigilance legislation allows patients to report adverse drug reactions
(ADRs) directly to competent authorities in all European Union (EU) member states. Patient
reporting is available in Portugal since July 2012. In 2013, the National Pharmacovigilance System
(SNF) had received 3461 spontaneous ADR reports, of which only 1.4% (n=50) were reported by
patients. Underreporting remains a reality in Portugal, although patient reporting could be one of
the measures to reduce the rate of underreporting by healthcare professionals (HCP).
Objectives: The aim of this study was to describe the attitudes and knowledge of the patients
regarding spontaneous reporting and the reasons and opinions that can influence patients ADR
underreporting.
Methods: A descriptive-correlational study was performed looking for patients’ attitudes and
knowledge regarding spontaneous reporting. A 6-months survey was conducted from June to
November 2013 in general adult patients from a community pharmacy in Coimbra, Portugal, that
used prescribed medicines or OTC-drugs. Attitudes and opinions were surveyed in a closedanswer
questionnaire using a Likert scale. Incomplete questionnaires and answers from
healthcare professionals were excluded from data analysis. The data were analyzed using
descriptive statistics, χ2 tests and Spearman’s correlation coefficients.
Results: A total of 1084 questionnaires were collected with a response rate of 81,1% and 948
completed questionnaires were selected for analysis. Of the respondents, 44.1% never heard
about SNF. Younger people and those with a higher education were significantly more likely to be
aware of SNF. Only 1 patient had previously reported an ADR directly to SNF. Reporting ADRs
indirectly through an HCP was preferred by 62.4%. The main reasons for patients reporting
spontaneous ADR would be the severity of the reaction (81,1% agreed or strongly agreed) and
worries about their own situation (73,4% agreed or strongly agreed). Only weak and moderate
correlations were found between studied statements.
Conclusions: Patients are most likely to do a spontaneous report about a severe reaction or if
they are worried about the symptoms. Tailored and proactive information on ADR reporting and
educational interventions on patients could increase the number of reports from patients in
Portugal
Attitudes and knowledge of community pharmacy professionals regarding the spontaneous reporting of adverse drug reactions: a preliminary study in Coimbra, Portugal
Background
Spontaneous reporting of adverse drug reactions (ADRs) remains one of the most efficient methods to detect new, unusual, and severe ADRs. Community pharmacy professionals (CPPs) play a fundamental role in the reporting of spontaneous ADRs. The aim of this study was to describe the attitudes and knowledge of different CPP groups regarding the spontaneous reporting of ADRs and to identify the factors that can influence ADR under-reporting.
Methods
A cross-sectional descriptive study was conducted in CPPs (156 pharmacists and 40 pharmacy technicians) working in 49 pharmacies in Coimbra, Portugal. A survey of the knowledge and attitudes of CPPs towards reporting ADRs and the factors that encourage and discourage ADR reporting was constructed and personally delivered to the pharmacies.
Results
The response rate was 82.0%. The seriousness and the unusualness of the reaction were the most important motives to report ADRs (98.0 and 97.4% of respondents, respectively). CPPs also considered ADR reporting to be a professional obligation (96.4%), but “don’t feel the need to report well-known ADRs” (54.1%). Other attitudes associated with under-reporting were lack of time (50.0%), method of reporting (38.3%), and fear of legal liability (29.6%).
Conclusions
CPPs’ knowledge and behavior play a significant role in ADR reporting. Despite the differences in their educational syllabus, there were no statistical differences between pharmacists and pharmacy technicians with regard to their perception of the importance of ADR reports or the factors that affect their reporting. It may be possible to reduce the under-reporting of ADRs by introducing educational interventions based on the attitudes related to under-reporting that have been identified in this study.info:eu-repo/semantics/publishedVersio
Are consumers ready to take part in the Pharmacovigilance System?—a Portuguese preliminary study concerning ADR reporting
BACKGROUND:
New pharmacovigilance legislation allows consumers to report adverse drug reactions (ADRs) directly to competent authorities in all European Union countries. Consumer reporting is available in Portugal since July 2012. In 2013, the National Pharmacovigilance System (SNF) had received 3461 spontaneous ADR reports, of which only 1.4% (n = 50) were from consumers. Consumer reporting could be one opportunity to reduce underreporting.
AIM:
The aim of this study was to describe the attitudes and knowledge of the general public regarding spontaneous reporting and the reasons and opinions that can influence consumers' ADR underreporting.
METHODS:
A descriptive-correlational study was performed looking for consumers' attitudes and knowledge regarding spontaneous reporting. A 6-month survey was conducted from June to November 2013 in general adult consumers from a community pharmacy in Coimbra, Portugal, who used prescribed medicines or over-the-counter (OTC) drugs. Attitudes and opinions were surveyed by personal interview in a closed-answer questionnaire using a Likert scale. Questionnaires from healthcare professionals or incomplete ones were not considered. Data were analyzed using descriptive statistics, chi-square (χ(2)) tests, and Spearman's correlation coefficients.
RESULTS:
One thousand eighty-four questionnaires were collected (response rate of 81.1%) and 948 completed were selected for analysis. Of the respondents, 44.1% never heard about SNF. Younger people and those with a higher education were significantly more likely to be aware of SNF. Only one consumer had previously reported directly an ADR. Reporting ADRs indirectly through a healthcare professional (HCP) was preferred by 62.4%. The main reasons for consumers reporting spontaneous ADR would be the severity of reactions (81.1% agreed or strongly agreed) and worries about their situation (73.4% agreed or strongly agreed). Only weak and moderate correlations were found between studied statements..
CONCLUSIONS:
Consumers are more likely to do spontaneous report about severe reactions or if they are worried about the symptoms. Tailored and proactive information on ADR reporting and educational interventions on consumers could increase the number of reports from consumers in Portugal.info:eu-repo/semantics/publishedVersio
Literatura infanto-juvenil e censura consequencias do pós-golpe
Orientador: Fábio de Carvalho MessaMonografia (graduação) - Universidade Federal do Paraná, Setor de Litoral, Curso de Licenciatura em Linguagem e ComunicaçãoInclui referênciasResumo: Este trabalho pretende verificar os equívocos de leitura e interpretação sobre textos infanto-juvenis - A Semente do Nicolau, de Chico Alencar; Meninos Sem Pátria, de Luiz Puntel; e A Bolsa Amarela, de Lygia Bojunga Nunes - que protagonizaram polêmicas e/ou conflitos no contexto escolar, no período da eleição do novo presidente do Brasil em 2018. A partir da seleção dessas manifestações, passamos à etapa de tentativa de compreensão do material produzido nas mídias (impressas e digitais) sobre as polêmicas envolvendo essas obras. Para isso foi preciso realizar uma leitura analítica integral das obras envolvidas para, então, contrastar com os enunciados das matérias geradas. Delimitamos, também, os temas que foram evidenciados como: doutrinação, comunismo, gênero e ideologia. Procuramos uma fundamentação para essas concepções, a fim de desfazer equívocos e banalizações. Mostramos, portanto, que as polêmicas são infundadas e que as obras têm muitas características interessantes e significativas para fins paradidáticos
Responsabilidade civil dos notários e dos registradores
Os serviços notariais e de registro são exercidos em caráter privado mediante delegação do
Poder Público. Os responsáveis pela execução dos serviços de nota e de registro são os
tabeliães e os oficiais de registro, e estes os executam nas dependências dos cartórios

Spectral Analysis of Marine Debris in Simulated and Observed Sentinel-2/MSI Images using Unsupervised Classification
Marine litter poses significant threats to marine and coastal environments,
with its impacts ever-growing. Remote sensing provides an advantageous
supplement to traditional mitigation techniques, such as local cleaning
operations and trawl net surveys, due to its capabilities for extensive
coverage and frequent observation. In this study, we used Radiative Transfer
Model (RTM) simulated data and data from the Multispectral Instrument (MSI) of
the Sentinel-2 mission in combination with machine learning algorithms. Our aim
was to study the spectral behavior of marine plastic pollution and evaluate the
applicability of RTMs within this research area. The results from the
exploratory analysis and unsupervised classification using the KMeans algorithm
indicate that the spectral behavior of pollutants is influenced by factors such
as the type of polymer and pixel coverage percentage. The findings also reveal
spectral characteristics and trends of association and differentiation among
elements. The applied methodology is strongly dependent on the data, and if
reapplied in new, more diverse, and detailed datasets, it can potentially
generate even better results. These insights can guide future research in
remote sensing applications for detecting marine plastic pollution.Comment: Manuscript submitted to Ocean and Coastal Research journa
Knowledge and consumption of emergency contraception pills in a tertiary education student population
Introduction
According to the World Health Organization (WHO), every year there are 200 million pregnancies, of which 75 million are unintended. Emergency contraception pills (ECPs) are one of the available methods to prevent an unintended pregnancy, after unprotected sexual intercourse or contraceptive failure. The aim of this study was to quantify the consumption, characterize the level of knowledge, and understand the factors that induce the use of ECPs in tertiary students.
Methods
An observational, cross-sectional, and retrospective survey was conducted at two tertiary education institutions (Coimbra Health School and Coimbra Education School) between January and April 2015. A written survey was applied to a convenience sample of female and male students at these schools. The survey questions comprised three areas: sociodemographic indicators; knowledge of ECPs; and previous consumption of ECPs (females only). Descriptive statistics and chi-square of independence test were used.
Results
Most of the students had heard about ECPs and used them mainly for “forgetfulness or contraceptive failure” (63.8%) or “sex without using a contraceptive” (22.4%). Students’ main information sources were school, friends, and the internet. There was a higher level of knowledge in female students, students from the Coimbra Health School (vs students from the Coimbra Education School), and students who had received healthcare professional counseling (p < 0.01). Regarding consumption, the majority (74.1%) were first-time users of ECPs and almost all ECPs were obtained in the pharmacy (91.4%).
Conclusions
In Portugal, ECPs are available over the counter, which facilitates their obtainment. There was some knowledge among students, however lack of information about this subject should be taken into account in further studies. Communication with the students to improve their risk perception and knowledge is key to improving the safer use of ECPs.info:eu-repo/semantics/publishedVersio
