Effectiveness of pharmacovigilance: multifaceted educational intervention related to the knowledge, skills and attitudes of multidisciplinary hospital staff

Oropharyngeal adverse drug reactions: knowledge, attitudes, and practice (KAP) among Italian healthcare professionals and students

Introduction

Pharmacovigilance plays a vital role in ensuring drug safety and protecting public health. Oropharyngeal adverse drug reactions (O-ADRs) are found to be under-reported, especially by oral health professionals, limiting the identification and management of these events.

Aims

This study aimed to evaluate the knowledge, attitudes, and practices (KAP) of healthcare professionals and students regarding O-ADRs and to assess their specific expertise by a self-e-learning test.

Materials and methods

A cross-sectional survey was conducted using a KAP questionnaire between April 2023 and April 2024, involving 943 participants, including physicians, dentists, dental hygienists, and students. Additionally, three sets of self-e-learning tests on O-ADRs were administered. The study employed descriptive statistics, Kruskal-Wallis tests, and logistic regression to analyze factors affecting KAP and reporting behaviors.

Results

Significant gaps in KAP were identified. Only 26.5% of participants demonstrated frequent best practices for reporting O-ADRs, with dentists and dental hygienists showing lower reporting rates (13.8% and 9.3%, respectively) compared to physicians (18.8%). The results of logistic regression analyses showed that practical knowledge was significantly associated with work experience (OR = 2.15, p = 0.026). Students exhibited the lowest levels of practical knowledge and reporting proficiency, with only 17.6% demonstrating competence. The self-e-learning test highlighted knowledge deficits: only 22.9% of participants correctly identified O-ADR associated with antiseptic mouth rinses, additional 30.2% recognized those linked to antimicrobial drugs.

Conclusions

This study highlights the need for targeted educational interventions to address gaps in O-ADR knowledge and practice. Tailored training, user-friendly digital tools, and a strong pharmacovigilance culture are crucial for improving reporting rates and ensuring patient safety.

PregMedNet: Multifaceted Maternal Medication Impacts on Neonatal Complications

While medication intake is common among pregnant women, medication safety remains underexplored, leading to unclear guidance for patients and healthcare professionals. PregMedNet addresses this gap by providing a multifaceted maternal medication safety framework based on systematic analysis of 1.19 million mother-baby dyads from U.S. claims databases. A novel confounding adjustment pipeline was applied to systematically control confounders for multiple medication-disease pairs, robustly identifying both known and novel maternal medication effects. Notably, one of the newly discovered associations was experimentally validated, demonstrating the reliability of claims data and machine learning for perinatal medication safety studies. Additionally, potential biological mechanisms of newly identified associations were generated using a graph learning method. These findings highlight PregMedNet's value in promoting safer medication use during pregnancy and maternal-neonatal outcomes.

[Strategies and Barriers to the Implementation of Continuing Education in Sentinel Hospitals for the Surveillance of COVID-19 Vaccine Safety in Honduras, 2022-2023Formação continuada: estratégias e barreiras de implementação em hospitais sentinela para a vigilância da segurança das vacinas contra a COVID-19 em Honduras, 2022-2023]

Objective

To describe the continuing education strategies implemented as part of the academic training of health workers; related barriers and facilitators; and the perceptions of health workers in sentinel hospitals in Honduras regarding changes in their knowledge.

Methods

The implemented continuing education strategies are described, as are the findings of a questionnaire given to assess health workers' perceptions of the effectiveness of these strategies in the acquisition of knowledge, skills, and competencies related to the surveillance of events supposedly attributable to vaccination, immunization, or adverse events of special interest. Barriers to participation in these strategies is also described.

Results

In the 2021-2023 period, 23 trainings were conducted with 384 participants, as well as two workshops with 134 participants, six rounds of awareness-raising with 242 professionals, 2 486 rounds of active searches twice a week in both sentinel hospitals, and an instant messaging system with 157 participants. The questionnaire obtained 154 responses from health workers. The main barriers were not realizing the questionnaire existed, limited availability of time, and no staff to replace them in the wards.

Discussion

The perception of health workers was that their knowledge increased and their ability to conduct sentinel surveillance improved. However, participation in continuing education strategies requires massive dissemination, the inclusion of topics that motivate professionals, and the implementation of an institutional policy that values the strategies and makes participation in them feasible.

Clozapine may consistently protect from suicidal behaviors while other antipsychotics may lack a specific protective effect: a comprehensive VigiBase study interpreted in the context of the prior literature

BACKGROUND

In the United States, clozapine was first approved for treatment-resistant schizophrenia and then for suicidality in schizophrenia psychoses. Systematic reviews support clozapine's anti-suicidal effect, but the forensic literature stresses its lethality during overdoses.

RESEARCH DESIGN AND METHODS

Clozapine reports to the international pharmacovigilance database (VigiBase) were analyzed for suicidal ideation, suicide attempts, intentional overdose, and completed suicides from introduction to 1 January 2024. VigiBase uses the information component (IC) as a disproportionality analysis.

RESULTS

The clozapine ICs (range: other antipsychotics) were: 1) suicidal ideation IC = 0.570 with IC025 = 0.454 to IC975 = 0.680 (IC = 3.568 for aripiprazole and 1.729 for risperidone), 2) suicide attempt IC = 1.428 with IC025 = 1.323 to IC975 = 1.529 (IC = 4.150 for quetiapine and 2.968 for risperidone), 3) intentional overdose: IC = 0.995 with IC025 = 0.864 to IC975 = 1.120 (IC = 4.080 for quetiapine and 1.957 for aripiprazole), and 4) completed suicide IC = 1.133 with IC025 = 1.026 to IC975 = 1.235 (IC = 4.648 for quetiapine and 2.160 for risperidone). In summary, all clozapine ICs were significantly lower. We found 2391 clozapine-treated patients on the suicidality spectrum (627 cases with suicidal ideation, 752 with suicide attempt, 488 with intentional overdose, and 731 with completed suicide) but many were taking other antipsychotics. The most frequent reporting countries were the United States, the United Kingdom, and Croatia.

CONCLUSION

This pharmacovigilance study, with all its inherent limitations, provides independent proof, not overlapping with prior literature, that clozapine may have specific strong anti-suicidal effects that do not appear to be present in other antipsychotics. Further VigiBase studies are needed to compare the lethality of an intentional overdose of clozapine (14.3%) with other antipsychotics.

Adverse drug reactions and their fatal outcomes in clozapine patients in VigiBase: Comparing the top four reporting countries (US, UK, Canada and Australia)

BACKGROUND

Pharmacovigilance findings and box warnings in the clozapine package inserts have marked the history of clozapine.

OBJECTIVE

This is the largest review of clozapine adverse drug reactions (ADRs) and their associated fatal outcomes. Reports to the World Health Organization's global pharmacovigilance database, VigiBase™, were analyzed, extending from clozapine's introduction to December 31, 2022.

METHODS

The analysis focused on the top four reporting countries: United States (US), United Kingdom (UK), Canada and Australia (83 % of fatal outcomes worldwide). Attempts were made to control for population and clozapine prescription in each country.

RESULTS

Clozapine ADRs worldwide accounted for 191,557 reports, with the highest number (53,505) in "blood and lymphatic system disorder". Of the 22,596 fatal outcomes reported in clozapine patients, 9587 were from the US, 6567 from the UK, 3623 from Canada and 1484 from Australia. The top category worldwide in fatal outcomes was nonspecifically labeled "death" with 46 % (range 22-62 %). "Pneumonia" was second with 30 % (range 17-45 %). Agranulocytosis was numerically only the 35th top clozapine ADR associated with fatal outcomes. On average, 2.3 clozapine ADRs were reported per fatal outcome. Infections were associated with 24.2 % of the UK fatal outcomes (9.4 %-11.9 % in the 3 other countries).

CONCLUSIONS

The four countries appeared to report clozapine ADRs in different ways, making comparisons difficult. We estimated higher fatal outcomes in the UK and Canada after controlling for cross-sectional estimations of population and published clozapine use. This last hypothesis is limited by the lack of precise estimation of accumulated clozapine use in each country.

Pharmacovigilance teaching and learning: a mixed cross-sectional analysis of the Portuguese public higher education system

Pharmacovigilance stands out for its importance in obtaining existing knowledge about medicine and patient safety and should be recognized as a continuous line of study. It constitutes a highly relevant component in the activities of health professionals, with spontaneous notification of suspected adverse drug reactions being its main emphasis. The underreporting that persists can be overcome through continuous professional development programs, reinforcing theoretical and practical knowledge in the curricular plans of health courses. As a result, more educated professionals will also allow citizens to recognize the importance of pharmacovigilance. The main objective of this study was to describe and characterize the teaching-learning process of pharmacovigilance in Portugal, analyzing the knowledge, perceptions and attitudes of students and health professionals. In total, ninety-three curricular unit forms of the seventeen healthcare courses included were analyzed, among which only three referred to pharmacovigilance as mandatory and thirty-nine did not address any keywords. The questionnaire applied was answered by 650 participants, both students (62%) and professionals (38%). Approximately 84.4% of the students and 54.7% of the professionals affirmed that they had never spontaneously reported an adverse drug reaction. Only 24.6% of the students and 17.8% of professionals referred to the existence of specific course content dedicated to pharmacovigilance in their coursework. In view of these results, it is evident that there is a need for a wider reflection regarding the further training and constant update of practicing professionals as well as in diverse health institutions, investing in the creation of an academic curriculum that integrates pharmacovigilance in healthcare courses.

An Awareness of Pharmacovigilance Among Healthcare Professionals Due to an Underreporting of Adverse Drug Reactions Issue: A Systematic Review of the Current State, Obstacles, and Strategy

BACKGROUND

Healthcare professionals play an essential role in reporting adverse drug reactions as part of pharmacovigilance activities. However, adverse drug reactions reported by healthcare professionals remain low.

OBJECTIVE

The aim of this systematic review was to investigate healthcare professionals' knowledge, awareness, attitude, and practice on pharmacovigilance and adverse drug reaction reporting, explore the causes of the underreporting issue, and provide improvement strategies.

METHODS

This systematic review was conducted using four electronic databases for original papers, including PubMed, Scopus, Google Scholar, and Scholar ID. Recent publications from 1st January 2012 to 31st December 2022 were selected. The following terms were used in the search: "awareness", "knowledge", "adverse drug reaction", "pharmacovigilance", "healthcare professional", and "underreporting factor". Articles were chosen, extracted, and reviewed by the two authors.

RESULTS

Twenty-five studies were selected for systematic review. This review found that 24.8%-73.33% of healthcare professionals were unaware of the National Pharmacovigilance Center. Around 20%-95.7% of healthcare professionals have a positive attitude toward pharmacovigilance and adverse drug reaction reporting, while 12%-60.8% of healthcare professionals have experience reporting any adverse drug reaction in their practice. The most frequently highlighted barriers to pharmacovigilance were a lack of awareness and knowledge regarding what, when, and to whom to report.

CONCLUSION

Underreporting issues require immediate attention among healthcare professionals due to a lack of awareness and knowledge of pharmacovigilance and adverse drug reaction reporting. Educational and training program interventions have been suggested by most studies to address these issues.

Knowledge of pharmacovigilance among healthcare professionals and the impact of an educational intervention

AIM

To determine the knowledge regarding various aspects of pharmacovigilance among doctors and nurses of a tertiary care teaching hospital and to evaluate the effect of an educational intervention.

METHODS

A cross-sectional study was conducted among doctors and nurses of a tertiary care teaching hospital. The participants attended a one-hour educational session during which the concept of pharmacovigilance, the Pharmacovigilance Program of India, the need for reporting ADRs, and the method of reporting were explained by a subject expert. A 20-item questionnaire was used to assess their knowledge regarding pharmacovigilance before and after an educational session. The pre-post comparisons were done using Wilcoxon's signed-rank test. A p-value less than 0.05 was considered statistically significant.

RESULTS

Forty-two doctors and 115 nurses participated in the study. A significant improvement in the participant scores was seen following the educational intervention in both doctors (Z = -5.344, p < 0.001) and nurses (Z = -8.808, p < 0.001). Lack of knowledge/awareness was perceived as the major barrier for ADR reporting among nurses as well as doctors.

CONCLUSION

There is need for education and training among doctors and nurses to enhance their knowledge about drug safety and reporting practices. Educational intervention is likely to improve the knowledge regarding pharmacovigilance, and thereby enhance reporting by healthcare professionals.

Strategies and interventions to strengthen pharmacovigilance systems in low-income and middle-income countries: a scoping review

OBJECTIVES

The slow progress of pharmacovigilance (PV) in low-income and middle-income countries (LMIC) raises questions about core challenges on the growth of PV, and the appropriateness of strategies used so far to develop PV. Therefore, this scoping review aims to describe strategies and interventions to strengthen PV in LMIC and to propose recommendations for future investments in PV capacity building.

INCLUSION CRITERIA

Publications included were primary studies, articles, policy and guideline papers, describing interventions to strengthen PV in LMIC.

METHODS

The review was conducted following the Joanna Briggs Institute (JBI) guidelines on conducting scoping reviews. Literature searches were performed in MEDLINE, EMBASE, Web of Science, PDQ-evidence, CINAHL and other relevant websites from January 1990 to January 2021. Two reviewers independently screened titles, abstracts and full texts. One reviewer performed data extraction and descriptive analysis, which were reviewed by two other reviewers.

RESULTS

10 922 unique titles were screened and 152 were eligible for full text review. Of these, 57 and an additional 13 reports from grey literature fulfilled eligibility criteria for inclusion in the review. These were grouped into two categories: (1) Interventions aimed at increasing PV knowledge and adverse drug reactions (ADR) reporting (45 papers), primarily education of healthcare professionals (HCP), alone or in combination with other interventions such as mobile and electronic reporting and (2) Interventions aimed at strengthening various components of the national PV system (25 papers), describing strategies or mixed interventions implemented at the national level, targeting different components of the national PV system.

CONCLUSIONS

Results of this review suggest that educating HCP on ADR reporting is the most common approach to build PV capacity in LMIC. Though important, education alone is insufficient and should ideally be organised within the holistic framework of strengthening national PV systems, with a focus on also building capacity for advanced activities such as signal detection.

Current career situations of Chinese pharmacovigilance professionals working for pharmaceutical companies: an exploratory survey

BACKGROUND

Pharmacovigilance in China has experienced rapid development in the past 30 years. The implementation of Good Pharmacovigilance Practice in China since the end of 2021 heralds a new era of pharmacovigilance affairs, which puts forward higher requirements for the quantity and quality of pharmacovigilance personnel. This study aimed to preliminarily explore the current career situations of pharmacovigilance professionals working in China for pharmaceutical companies.

METHODS

A questionnaire was adapted from research in the USA and Europe with the help of several pharmacovigilance experts. Snowball sampling was used to conduct an exploratory survey to obtain the frequency of basic demographic information, work status, and career expectations of pharmacovigilance professionals working for pharmaceutical companies.

RESULTS

The personnel engaged in pharmacovigilance work for pharmaceutical companies were mainly medical or pharmaceutical undergraduates within 3 years of graduation. Their work intensity and pressure were relatively high. The training provided by their universities and enterprises could not well meet their needs to improve their job competence. Although they were optimistic about pharmacovigilance and will not change their career, most of them were planning to change their employers.

CONCLUSION

There was a gap between the demand and supply of pharmacovigilance personnel. Relevant regulatory authorities and industry associations should guide higher education institutions to collaborate with pharmacovigilance specialists to strengthen pharmacovigilance education for medical or pharmaceutical students, on the basis of which pharmacovigilance certification courses and continuing education courses can be developed. Meanwhile, pharmaceutical enterprises should consider reasonably adjusting work intensity and income to avoid a high turnover rate.

[Central nervous system adverse events potentially associated with drugs used for COVID-19: scoping reviewEventos adversos en el sistema nervioso central potencialmente relacionados con los medicamentos para tratar la COVID-19: revisión exploratoria]

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.

Effectiveness of a structured stimulated spontaneous safety monitoring of medicines reporting program in strengthening pharmacovigilance system in Tanzania

Under-reporting of adverse drug events (ADEs) is a challenge facing developing countries including Tanzania. Given the high magnitude of under-reporting, it was necessary to develop and assess the effectiveness of a ‘structured stimulated spontaneous safety monitoring’ (SSSSM) reporting program of ADEs which aimed at strengthening pharmacovigilance system in Tanzania. A quasi-experimental design and data mining technique were used to assess the effect of intervention after the introduction of program in seven tertiary hospitals. ADEs reports were collected from a single group and compared for 18 months before (July 2017 to December, 2018) and after the program (January 2019 to June 2020). Out of 16,557 ADEs reports, 98.6% (16,332) were reported after intervention and 0.1% (23) death related to adverse drug reactions (ADRs) were reported. Reports increased from 20 to 11,637 after intervention in Dar es salaam, 49 to 316 in Kilimanjaro and 17 to 77 in Mbeya. The population-based reporting ratio per 1,000,000 inhabitants increased from 2 reports per million inhabitants in 2018 to 85 reports in 2019. The SSSSM program can increase the reporting rate of ADEs and was useful in detecting signals from all types of medicines. This was first effective developed spontaneous program to monitor medicine safety in Tanzania.

Characteristics of hospitals that report adverse drug reactions: Results of a nationwide survey in Japan

WHAT IS KNOWN AND OBJECTIVE

Adverse drug reactions (ADRs) are one of the primary reasons for hospitalization. The spontaneous reporting of ADRs by healthcare professionals is important for issuing post-marketing drug safety measures. The Japanese Society of Hospital Pharmacists (JSHP) conducts a nationwide survey annually. Using data from this large-scale survey, we identified the characteristics of hospitals that reported ADRs to regulatory authorities and pharmaceutical companies.

METHODS

Data were obtained from annual surveys conducted by JSHP from 2015 to 2020. All variables were expressed as categorical variables and tabulated. The Chi-square test was used to compare the categorical variables. The Cochran-Armitage trend test was used to identify significant trends in the proportion of hospitals reporting ADRs.

RESULTS AND DISCUSSION

From 2015 to 2020, 22,362 responses were recorded. There was a significant increase in the proportion of hospitals that reported ADRs with an increase in number of beds and pharmacists (p < 0.0001). The proportion of hospitals reporting ADRs to regulatory authorities was also significantly higher in those charging an additional fee for pharmacist-performed ward operations and in those with an ADR data management section than in hospitals without these attributes (p < 0.0001).

WHAT IS NEW AND CONCLUSION

Hospitals that submitted ADR reports to the regulatory authorities and pharmaceutical companies charged an additional fee for pharmacist-performed ward operations, had a central ADR data management section, and had fewer beds per pharmacist. This trend was similar, regardless of the size of the hospital.

Traditional Lectures Actually Improve the Body of Knowledge, Skills, and Attitudes of Health Care Professional for Health Incident Reporting System

Introduction: A solid patient safety culture lies at the core of an effective event reporting system in a health care setting requiring a professional commitment for event reporting identification. Therefore, health care settings should provide strategies in which continuous health care education comes up as a good alternative. Traditional lectures are usually more convenient in terms of costs, and they allow us to disseminate data, information, and knowledge through a large number of people in the same room. Taking in consideration the tight money budgets in Brazil and other countries, it is relevant to investigate the impact of traditional lectures on the knowledge, skills, and attitudes to incident reporting system and patient safety culture. Objective: The study aim was to assess the traditional lecture impact on the improvement of health care professional competency dimensions (knowledge, skills, and attitudes) and on the number of health care incident reports for better patient safety culture. Participants and Methods: An open-label, nonrandomized trial was conducted in ninety-nine health care professionals who were assessed in terms of their competencies (knowledge, skills, and attitudes) related to the health incident reporting system, before and after education intervention (traditional lectures given over 3 months). Results: All dimensions of professional competencies were improved after traditional lectures (P < .05, 95% confidence interval). Conclusions: traditional lectures are helpful strategy for the improvement of the competencies for health care incident reporting system and patient safety.

Pharmacovigilance education to healthcare professionals: Will it affect their performance in reporting adverse drug reactions?

AIM

To assess impact of pharmacovigilance (PV) educational program on knowledge, attitude and practice (KAP) of healthcare professionals (HCPs).

METHODS

a prospective study was conducted on HCPs at an Egyptian hospital. The study included: pre-education phase; where KAP questionnaire was administered by HCPs to obtain baseline data, intervention phase; where educational sessions were held by clinical pharmacists and Egyptian PV centre, and post-education phase; where the questionnaire was re-administered by participants 9 months post-receiving educational sessions. The questionnaire comprised five sections: participants' demographics, knowledge, attitude and practice sections and two multiple choice questions asking about the importance of establishment of ADRs monitoring centre, and factors hindering ADRs reporting. Pre-education and post-education data were compared.

RESULTS

From 221 HCPs invited to participate, only 153 filled the pre-education and post-education questionnaires. At baseline, the median (range) of the total KAP score were 1 (0-7), 1 (0-4) and 4 (0-14) for physicians, nurses and pharmacists, respectively. All KAP scores were low for all HCPs at baseline with the pharmacists having significantly higher knowledge and attitude scores compared with physicians, and nurses (P < .001). After education, all scores significantly increased and 13 ADRs were reported by HCPs compared with only 2 at baseline.

CONCLUSION

It was concluded that educational program had a significant impact on enhancing KAP of HCPs towards PV and ADRs reporting.

The severity of adverse drug reactions and their influencing factors based on the ADR monitoring center of Henan Province

Adverse drug reactions (ADRs) may be a serious public health problem and have received widespread attention in recent years. This study has analyzed the factors leading to the occurrence of serious ADRs (SADRs), determined the factors affecting the prognosis of patients with severe adverse reactions at different levels of medical institutions, and finally made corresponding recommendations for the monitoring, prevention, and treatment of SADRs. We used descriptive analysis and chi-square test to analyze the year, age, gender, proportion of SADRs, and the results of the ADRs in the report. Use the logistic regression to analyze the factors affecting the prognosis of SADRs in different levels of medical institutions. A total of 387 642 people’s 394 037 ADRs were collected from the Henan Provincial Adverse Drug Reaction Monitoring Center from 2016 to 2020. Among them 35 742 cases of serious ADRs (9.1%), 96.1% were eventually relieved or cured, but 39 cases of SADRs caused death. The main causes of death included hemorrhages, organ failure, and allergies. Age, number of medication and illnesses, level of medical institution, history of adverse reactions, and type and method of medication were all factors that affected the severity of ADR. The prognosis of SADRs is worse than normal ADRs. The ADRs in autumn and winter and new adverse reactions are unique risk factors found in this study. The elderly and patients with multiple diseases or taking multiple drugs should pay attention to their adverse reactions. They should be closely observed within a week after taking the medicine. The supervision of patients with a history of allergies and new adverse reactions should be strengthened by primary medical institutions, and in nonprimary medical institutions should paid attention with past medical histories, and use imported drugs and biological agents with caution to ensure the safety and health of patients.

Methods for the detection of adverse drug reactions in hospitalized children: a systematic review

Introduction: Adverse drug reactions (ADR) are a problem for healthcare systems worldwide. Pediatric patients constitute a vulnerable group with regard to ADRs. However, although pediatric patients are at increased risk for these reactions, there is little progress on ADR detection methods in this group.Areas covered: In this systematic search, performed according to PRISMA statements, we selected studies, published in PubMed/Medline databases; Scopus; LILACS; Web of Science; Embase and Cochrane Library until April, 2020, on ADRs in hospitalized pediatric patients.Expert opinion: The increase of pediatric drug safety data is essential to the improvement of childcare. Health services must continuously stimulate educational programs focused on ADR detection tools to minimize the barriers and raise awareness among professionals. Therefore, it is necessary to consider that each method has advantages and disadvantages and must be analyzed in detail to be implemented according to the peculiarities of each practice scenario. Triggers tools (active method) correlated with electronic medical notes seems a good strategy for ADR identification, whether pediatric parameters are well checked and adapted with each age group. In any event, combined methods will add data to identification and clearer ADR assessment.

Interventions to improve adverse drug reaction reporting: A scoping review

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.

Challenges to the consolidation of pharmacovigilance practices in Brazil: limitations of the hospital pharmacist

Aims:

The aim of this study was to present the needs of hospital pharmacists in pharmacovigilance practices.

Methods:

This study has a cross-sectional design and was carried out with hospital pharmacists in Brazil. The sample was obtained by voluntary recruitment. Pharmacists who worked at Brazilian hospitals and were registered in their respective regulatory councils were invited to participate in the present study. A personalized questionnaire was developed by the authors and was electronically filled out by the respondents on the platform ‘Google forms’. The questionnaire was nationally available on the digital platform of the Pharmacy Federal Council, the Brazilian Society of Hospital Pharmacy and Health Services, four Pharmacy regional councils and the social network farmacêuticoclínico^®. Quantitative variables were analyzed by mean and standard deviation. The qualitative variables were analyzed by means of absolute and relative frequency. Difficulties related to pharmacovigilance activities are presented in an Ishikawa diagram in the Supplemental Material online.

Results:

Of the 27 federative units of Brazil, we obtained answers from pharmacists located in 85.2% (n = 23) of them. Among the pharmacovigilance practices developed by Brazilian pharmacists, the adverse drug reaction investigation (55.4%) and notification activities (47.0%) were worthy of note. Numerous difficulties were reported by the pharmacists, highlighting the difficulty in monitoring the medication and imputation of causality (27.7%). After categorizing the difficulties reported, it was observed that the category ‘people involved’ (45.1%) stood out from the others.

Conclusion:

This study pointed out numerous challenges to pharmacovigilance practices involving pharmacists in Brazil. It is believed that the correction of certain difficulties may impact on the better consolidation of pharmacovigilance activities in the country. However, regulatory agencies at all hierarchical levels of pharmacovigilance must work together to make it possible.

Plain language Summary

Challenges to the consolidation of pharmacovigilance

This is a study that seeks to present the needs of Brazilian hospital pharmacists in relation to pharmacovigilance activities. Through online interviews, pharmacists answered a questionnaire, presented the pharmacovigilance activities they develop and expressed their anxieties and difficulties for the development of these activities. With this study, it was concluded that numerous activities of active search, investigation and notification of adverse drug reaction are developed by Brazilian pharmacists. However, each pharmacist performs a different method of pharmacovigilance. In addition, it was observed that among the interviewees there was a perception of insufficient professional training and a shortage of professionals to assist in pharmacovigilance activities. These were the main difficulties reported. Therefore, the search for models or agile solutions to solve problems involving adverse drug reactions seems necessary for a better consolidation of pharmacovigilance services in Brazil.

Monitoring adverse effects of marketed medicines through reporting by healthcare professionals and its challenges and way forward.

INTRODUCTION

This article highlights the importance of safety monitoring of medicines after they are launched in the market, mainly through reporting by healthcare professionals. We also highlight the strengths and weaknesses, and provide an insight on the future prospects of pharmacovigilance systems.

METHODS

Various literature related to the topic were reviewed and the relevant ones highlighting the strengths and weaknesses are summarized. A balance of information on strengths and weaknesses is listed. Health professionals' awareness regarding existing programs on reporting safety of medicines is highlighted.

RESULTS

Though beneficial, reporting of adverse effects by healthcare professionals who deal with patient lacks clarity in diagnosing the adverse effects. Under-reporting and bias are the major challenges. Online software is needed to strengthen reporting by healthcare professionals. We list the various issues to be considered while depending on healthcare professionals' reporting of adverse effects as a method of post marketing surveillance.

CONCLUSION

To strengthen medicine safety monitoring and reporting by healthcare professionals, more awareness among health professionals and innovative strategies are needed. Integrating the genetic data of patients can be beneficial in predicting adverse effects, therefore avoiding them and enhancing safe prescribing and dispensing by healthcare professionals.

The comparative assessment of awareness, perspective, and basic practice skills about the Saudi pharmacovigilance system among students of different health-care professionals of a Saudi Female University

INTRODUCTION

The low reporting of adverse drug reactions (ADRs) in Saudi Arabia is prevalent among health-care professionals and is responsible for poor ADR signal detection. Therefore, all healthcare institutes connected with patient concern require joint and sustained efforts to strengthen ADR reporting by providing harmless and efficient medication.

OBJECTIVES OF THE STUDY

The current study was performed to estimate the awareness corresponding to the knowledge, perspective, and basic practice skills about the Saudi pharmacovigilance system among students of different health-care professionals of a Saudi Female University.

MATERIAL & METHODS

A questionnaire was planned and standardized by a thorough literature review. Questions were classified: Group 1 had ten knowledge-based, group 2 five attitude-based, and group 3 four basic practice skills-based questions of pharmacovigilance (PV). Also, determinants that hindered them from becoming part of the pharmacovigilance program were reported. Such 600 questionnaires were distributed among the interns, final and prefinal year students of different health care professionals of Princess Nourah bint Abdulrahman University, Riyadh. The participants' awareness and practice skills were graded in 3 categories as unacceptable, inadequate, and adequate, depending upon the mean score along with identification of their type of perception towards PV. The data was interpreted by calculating the frequencies, one-way ANOVA, and by post-hoc Tukey-Kramer HSD multiple comparison test.

RESULTS

Five hundred ninety-two questionnaires were statistically investigated. Students' awareness and basic practice skills of pharmacovigilance were found to be inadequate, but positive perception towards PV.

CONCLUSION

Our study showed that awareness and practice skills of PV among students of different health care professionals stand insufficient but favourable perceptions towards PV. Regular educative interventions can increase these parameters of pharmacovigilance.

Impact of an educational intervention on pharmacovigilance knowledge and attitudes among health professionals in a Nepal cancer hospital

BACKGROUND

Pharmacovigilance (PV) knowledge and attitudes among health care professionals (HCPs) directly affect the practice of PV and reporting of adverse drug reactions (ADRs) in a hospital. The main aim of the study was to assess the impact of an education intervention on the knowledge and attitude of HCPs attached to the regional PV center in an oncology based hospital of Nepal.

METHODS

A pre-post intervention questionnaire-based study was conducted amongst HCPs, i.e. nurses and pharmacists of an oncology based hospital of Nepal. A 21-item pretested PV questionnaire (twelve and four statements for assessing knowledge and attitude respectively) was used before and after an educational intervention among 89 HCPs working in the hospital. SPSS version 21.0 was used to analyze pre- and post-survey data with descriptive and inferential statistics. The knowledge and attitude scores before and after educational intervention were analyzed with Wilcoxon rank-sum test.

RESULTS

After the educational intervention, the mean score for knowledge about PV and ADR increased from [mean ± S.D] 6.90 ± 2.527 (pre-test) to 11.36 ± 1.189 (post-test, p < 0.001). There were significant improvements after an educational intervention in attitude from 1.80 ± 0.932 (pre-test) to 3.61 ± 0.556 (post-test, p < 0.001). Twenty-one (23.6%) of participants responded that they lacked the time to report ADR, while 12 (13.5%) replied that there was no remuneration for reporting ADR. Approximately 24% of them recommended frequent pharmacovigilance awareness programs via continuing medical education or other similar kinds of workshops for improvement of pharmacovigilance.

CONCLUSION

The preliminary findings of this study showed that knowledge and attitude scores were increased following an educational intervention. They also suggested that training on PV and ADR tends to have a positive impact on knowledge and attitude among nurses and pharmacists working at an oncology based hospital in Nepal.

Pharmacovigilance in perspective: drug withdrawals, data mining and policy implications

Considering that marketed drugs are not free from side effects, many countries have initiated pharmacovigilance programs. These initiatives have provided countries with methods of detection and prevention of adverse drug reactions at an earlier stage, thus preventing harm occurring in the larger population. In this review, examples of drug withdrawals due to effective pharmacovigilance programs have been provided with details. In addition, information concerning data mining in pharmacovigilance, an effective method to assess pharmacoepidemiologic data and detecting signals for rare and uncommon side effects, is also examined, which is a method synchronized with information technology and advanced electronic tools. The importance of policy framework in relation to pharmacovigilance is discussed in detail, and country experiences upon implementation of pharmacovigilance policies is highlighted.

The Efficiency of Multi-Faceted Educational Intervention on Knowledge, Perceived Behavior, and Practice Skills towards Pharmacovigilance among Undergraduate Pharmacy Students of India

BACKGROUND

The primary reason for poor adverse drug reaction (ADR) signal detection worldwide is the under-reporting of ADRs by healthcare professionals. Multidisciplinary teams, including pharmacists, may play an essential role in targeting this issue.

AIM

The purpose of the study was to evaluate the impact of a multi-faceted educational intervention (MEI) on the knowledge, perception, and practice skills of pharmacovigilance among undergraduate pharmacy students.

METHODS

A longitudinal, prospective study using a single group before-and-after intervention design was conducted among 100 undergraduate pharmacy students at Togari Veeramallappa Memorial College of Pharmacy, Ballari, India (TVMCP), affiliated to Vijayanagara Institute of Medical Sciences (VIMS), Ballari, India. The questionnaire was structured using previous studies and standardized. It had three groups of questions. Group 1 questions evaluated the knowledge (K1-K8), group 2 tested perceptions (A1-A6), and group 3 tested the practice skills of pharmacovigilance (P1-P5) of the participant. The participants were graded in 3 categories as poor, unsatisfactory, and satisfactory, depending upon the mean score. Matched pairs student t-test and The Wilcoxon Signed rank statistical test was used to assess the impact of the MEI on the participants' knowledge, perception, and practice skills score, along with recording different factors preventing them from being actively involved in the pharmacovigilance program.

RESULTS

The educational intervention improved the pharmacovigilance knowledge, perception, and practice skills scores of our pharmacy students.

CONCLUSION

Our study showed that knowledge, perception, and practice skills scores increased after MEI highlighting the need for regular educational campaigns to healthcare professions.

Factors associated with spontaneous adverse drug reaction reporting among healthcare professionals in Vietnam

WHAT IS KNOWN AND OBJECTIVE

Under-reporting is a major drawback of a voluntary adverse drug reaction reporting system in pharmacovigilance. However, little is known about facilitators and barriers to ADR reporting by healthcare professionals (HCPs) in developing countries. To investigate factors associated with adverse drug reaction (ADR) reporting among HCPs in Vietnam.

METHODS

A cross-sectional survey of 2091 HCPs was conducted in 2015 at 10 hospitals throughout Vietnam. The binary outcome was ever reporting ADRs. Healthcare professionals knowledge, attitude and practice about ADR reporting were measured. Multiple logistic regression analyses examined factors significantly associated with ever ADR reporting.

RESULTS

Overall, 29.3%, 2.2% and 68.4% of the sample were doctors, pharmacists and nurses, respectively. More than half (59.3%) had ever reported any ADR. Facilitators for ADR reporting were educational training (OR = 1.77, 95%CI = 1.42-2.22) and having better knowledge, such as awareness of ADR reporting regulation (OR = 1.63, 95%CI = 1.19-2.21), of reporting time (OR = 1.76, 95%CI = 1.35-2.29) and of necessary information in reporting form (OR = 1.94, 95%CI = 1.53-2.45).Conversely, barriers to non-reporting were unknown of reporting procedure (OR = 0.27, 95%CI = 0.22-0.35), unavailability of reporting form (OR = 0.54, 95%CI = 0.42-0.68) and lack of time (OR = 0.59, 95%CI = 0.46-0.74).

WHAT IS NEW AND CONCLUSION

Given the low ADR reporting rate among HCPs, educational interventions to improve their knowledge and attitude should be prioritized in Vietnam. Additional interventions addressing obstacles (i.e. availability and complexity of reporting form, lack of time) should be considered to improve both the quantity and quality of ADR reporting.

Barriers towards effective pharmacovigilance systems of biosimilars in rheumatology: A Latin American survey

Purpose

This review summarises the current status of regulatory guidelines for the approval of biosimilars in Latin America and highlights the main barriers to effective pharmacovigilance in this region. We also report results from a survey of Latin American rheumatologists assessing their understanding of prescribing biosimilars and the pharmacovigilance of these drugs.

Methods

We reviewed the current guidelines for the regulatory approval of biosimilars and barriers to effective pharmacovigilance in Latin American countries. Rheumatologists attending the II Pan‐American League of Rheumatology Associations PANLAR Review Course (Biosimilars update) in Lima, Peru were asked to complete a short survey to determine their knowledge of biosimilars.

Results

Many Latin American countries continue to lag behind Europe and the United States in establishing regulatory guidance and effective pharmacovigilance systems for biosimilars. Results from our survey also highlight a lack of awareness regarding the availability of biosimilars, their nomenclature, automatic substitution, and reporting adverse drug reactions because of these drugs.

Conclusions

The main barriers to effective pharmacovigilance in Latin America are the lack of consensus on the interchangeability of reference biologics and biosimilars, and the need for more suitably trained personnel to carry out effective postmarketing pharmacovigilance of biosimilars. Inconsistencies in biosimilar nomenclature make it difficult to adequately trace drugs and record adverse drug reactions associated with their use, creating a barrier to the global pharmacovigilance of biologics.

Educational intervention to improve the knowledge, attitude and practice of healthcare professionals regarding pharmacovigilance in South-South Nigeria

Background

Our aim in this study was to evaluate the effect of a combined educational intervention and year-long monthly text message reinforcements via the Short Messaging System (SMS) on the knowledge, attitude and practice (KAP) of healthcare professionals (HCPs) towards pharmacovigilance.

Methods

Six randomly selected teaching hospitals in the South-South zone of Nigeria were randomized in 1:1 ratio into intervention and control groups. The educational intervention consisted of delivering a seminar followed by sending monthly texts message reinforcements via SMS over 12 months. Then a semi-structured questionnaire regarding the KAP of pharmacovigilance was completed by HCPs working in the hospitals after the intervention. Data was analysed descriptively and inferentially.

Results

A total of 931 HCPs participated in the post intervention study (596 in the intervention and 335 in the control). The M:F ratio was 1:1.5. According to the KAP questionnaire, a significant difference was observed between the intervention and control groups, regarding knowledge of the types of adverse drug reactions (ADRs). ADR resulting from pharmacological action of the drug (85.6% versus 77%, p = 0.001), the fact that ADRs can persist for a long time; (60.1% versus 53.4%, p = 0.024) and a higher awareness of the ADR reporting form (48.7% versus 18.8%, p < 0.001). Most respondents in the intervention group (68.5% versus 60.6%, p = 0.001) believed they should report ADRs even if they were unsure an ADR has occurred, a greater proportion of HCPs from the intervention group had significantly observed an ADR (82% versus 73.4%, p = 0.001). Furthermore, of the 188 who had ever reported an ADR, 41% from the intervention group used the national ADR reporting form compared with 19.8% from the controls (p < 0.001).

Conclusion

This educational intervention and the use of SMS as a reinforcement tool appeared to have positively impacted on the knowledge and practice of pharmacovigilance in South-South Nigeria with a less-than-impressive change in attitude. Continuous medical education may be required to effect long-lasting changes.

Healthcare professionals' pharmacovigilance knowledge and adverse drug reaction reporting behavior and factors determining the reporting rates

Background: Spontaneous adverse drug reaction (ADR) reports prepared by healthcare professionals (HCPs) are the backbone of collecting post-marketing safety data. However, underreporting is a global problem creating health, economic, and ethical burden.

Objectives: To determine the factors limiting ADR reporting rates from the HCPs’ point of view.

Methods: A questionnaire containing 43 questions evaluating sociodemographic characteristics, pharmacovigilance knowledge and activities, and prescription behaviors was prepared on “surveymonkey.com.” The link was distributed mainly by professional organizations.

Results: Although this survey aimed to reach all HCPs, most of the respondents were physicians and nurses. Of the 259 (69.6%) participants who encountered ADR at least once, only 105 (40.5%) reported ADR. The term “pharmacovigilance” was heard for the first time in this survey by 35.5% (n = 132) of the participants. Only 34.7% (n = 129) of the participants knew where to find the ADR reporting form, and 25.5% (n = 95) had previously filled the form and/or read it. Only 28.5% (n = 106) of the participants were aware of the ADR reporting and monitoring system of their institutions and related professionals. Almost all the participants agreed that pharmacovigilance and ADR reporting training are necessary.

Conclusion: The main reason for underreporting is limited pharmacovigilance knowledge of HCPs. Training activities based on the needs and preferences of HCPs and close follow-up by authorities are the main steps to improve pharmacovigilance activities.

Incidents reporting: barriers and strategies to promote safety culture

OBJECTIVE

The purpose was to identify the barriers of underreporting, the factors that promote motivation of health professionals to report, and strategies to enhance incidents reporting.

METHOD

Group conversations were carried out within a hospital multidisciplinary team. A mediator stimulated reflection among the subjects about the theme. Sixty-five health professionals were enrolled.

RESULTS

Complacency and ambition were barriers exceeded. Lack of responsibility about culture of reporting was the new barrier observed. There is a belief only nurses should report incidents. The strategies related to motivation reported were: feedback; educational intervention with hospital staff; and simplified tools for reporting (electronic or manual), which allow filling critical information and traceability of management risk team to improve the quality of report.

CONCLUSION

Ordinary and practical strategies should be developed to optimize incidents reporting, to make people aware about their responsibilities about the culture of reporting and to improve the risk communication and the quality of healthcare and patient safety.
