Promoting adverse drug reaction reporting: comparison of different approaches

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.

Use of Antidepressants and the Risk of Upper Gastrointestinal Tract Bleeding: A Case-control Study

PURPOSE

To investigate the association between the use of antidepressants and the risk of upper gastrointestinal tract bleeding (UGIB).

METHODS

A Case-control study was conducted in a Brazilian hospital complex. Cases were defined as patients with a diagnosis of UGIB and controls as patients admitted for reasons unrelated to gastrointestinal bleeding, gastric concerns, or complications associated with low-dose aspirin (LDA) or nonsteroidal anti-inflammatory drugs (NSAIDs) use. Sociodemographic and clinical data, comorbidities, drug therapy in use (long-term use and self-medication), and lifestyle habits were recorded through face-to-face interviews. Two groups were defined: use of antidepressants in general and use of antidepressants according to their affinity for serotonin transporters. The presence of synergism between the concomitant use of antidepressants and LDA or NSAIDs on the risk of UGIB was also explored.

FINDINGS

A total of 906 participants were recruited (200 in the case group and 706 in the control group). The use of antidepressants was not associated with the risk of UGIB (odds ratio [OR] = 1.503; 95% CI, 0.78-2.88) or the use of antidepressants with high affinity for serotonin receptors (OR = 1.983; 95% CI, 0.81-4.85). An increased risk of UGIB was observed in concomitant users of antidepressants and LDA (OR = 5.489; 95% CI, 1.60-18.81) or NSAIDs (OR = 18.286; 95% CI, 3.18-105.29). Despite the lack of significance, the use of antidepressants appears to be a positive modifier of UGIB risk in LDA and NSAID users.

IMPLICATIONS

These findings indicate an increased risk of UGIB in concomitant users of antidepressants and LDA or NSAIDs, suggesting the need to monitor antidepressant users, especially those most likely to develop UGIB. In addition, further studies with larger sample sizes are needed to confirm these findings.

Adverse Drug Reactions and Potentially Inappropriate Medication in Older Patients: Analysis of the Portuguese Pharmacovigilance Database

Criteria have been developed to identify potentially inappropriate medications that can enhance adverse reactions, highly prevalent in older patient’s therapy. This study aimed to identify potentially inappropriate medications within the adverse drug reactions reported in the Portuguese pharmacovigilance system, characterizing the reports where inappropriate medications were identified. INFARMED, I.P. provided all adverse drug reactions reported from January to December 2019 in 65-year-old and older patients. Adverse drug reactions were characterized according to the System Organs Classes, seriousness, and medications with the Anatomical Therapeutical Classification. Potentially inappropriate medications were identified by applying the EU-(7)-PIM and the Beers criteria. A p value < 0.05 was considered statistically significant. From the 2337 reports considered for the analysis, PIMs were found in 12.8% of these, and 64.7% of all adverse reaction reports were classified as serious. Within the group of reports including at least one PIM, 71.4% were classified as serious, with hospitalization the most common criteria (35.1%). From the 3170 suspected medicines identified, 10.6% were classified as PIMs. Amiodarone was the most frequent PIM identified in the study (10.1%). Reports including at least one PIM were more associated with a higher number of ADRs (p = 0.025) reported in the same record, higher number of suspected medicines identified (p < 0.001), seriousness (p = 0.005), and hospitalization (p < 0.001). Potentially inappropriate medications are important enhancers of serious adverse drug reactions, increasing the likelihood of hospitalizations. This reinforces the importance of improving medication appropriateness in the older population.

[Looking back on 20 years of work at the Porto Pharmacovigilance Centre, Portugal]

Since 1963, the World Health Organization has acknowledged pharmacovigilance as a priority area in global public health, guaranteeing permanent monitoring of drug safety. This study aimed to characterize the reports of adverse drug reactions received by the Porto Pharmacovigilance Centre (UFPorto), Portugal, in the unit's two decades of work. The analysis included all reports of suspected adverse drug reactions received from January 2001 to December 2019. We calculated the annual reporting rates and distribution by origin, type of notifier and place of work, severity, prior knowledge, and causality of the reported adverse drug reactions. During the study period, UFPorto received 9,711 notifications of suspected adverse drug reactions. Hospital institutions reported the most suspected adverse drug reactions (n = 6,003; 64%), as did physicians among healthcare workers (n = 5,284; 54.4%). The most frequently reported adverse events were severe (n = 6,275; 72%) and are described in the respective Summary of Product Characteristics (n = 6,978; 72%). Most of the reports received by UFPorto were evaluated as having "probable" causality (n = 7,473; 77%), independently of the type of notifier. The results are consistent with other data previously reported in the international medical literature and official national reports. However, the underreporting rates are still higher than expected. In approximately 20 years, UFPorto has experienced an increase in its activity in various areas of drug safety.

Adverse Drug Reactions in Norway: A Systematic Review

Prescription medicines aim to relieve patients' suffering but they can be associated with adverse side effects or adverse drug reactions (ADRs). ADRs are an important cause of hospital admissions and a financial burden on healthcare systems across the globe. There is little integrative and collective knowledge on ADR reporting and monitoring in the Norwegian healthcare system. Accordingly, this systematic review aims to investigate the current trends in ADR reporting, monitoring, and handling in the Norwegian healthcare system and describe related interventions. Appropriate keywords, with regard to ADRs in both English and Norwegian languages, were used to retrieve articles published from 2010 to 2019. Six articles met the inclusion criteria. The findings offer a comprehensive picture of ADR reporting and monitoring in the Norwegian healthcare system. Psychotropic medicines were most commonly implicated by patients, while professionals most commonly reported ADRs associated with anticoagulants. The current ADR systems were compiled with the involvement of both patients and healthcare providers to record all types of drugs and ADRs of various severities, and aimed at improving ADR tracking. However, there is a need to improve current initiatives in terms of feedback and quality, and more studies are needed to explore how ADR profiles, and the associated vigilance, can improve the safety of medicines management in Norway.

Reporting of adverse drug reactions in India: A review of the current scenario, obstacles and possible solutions

Pharmacovigilance is a practice aimed to monitor drug safety in real life conditions and capture adverse drug events during the post marketing phase of drug's life cycle. But under reporting of adverse reactions is a major cause of concern and a threat to the pharmacovigilance systems. The present article looks into the major obstacles affecting the spontaneous reporting of adverse drug reactions (ADRs) in India and the possible solutions. As per available scientific literature, the major impediments to ADR reporting are inadequate knowledge and awareness among health professionals, clinicians' perceptions towards reporting, problems with establishing reporting systems in hospitals and insufficient training to recognize ADRs. Measures to improve the situation include greater involvement of nurses, pharmacists as well as consumers in the reporting of ADRs, making the process simpler and faster through electronic means, introducing educational interventions and training programs for health care providers and spreading awareness about the reporting system amongst caregivers and receivers alike. Providing a momentum to the pharmacovigilance system and ensuring a robust reporting process is a challenge but proper planning, feasible solutions and focussed efforts can help bring about the change ensuring patient safety - the ultimate goal of pharmacovigilance.

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.

Urgent need to modernize pharmacovigilance education in healthcare curricula: review of the literature

OBJECTIVES

Pharmacovigilance education is essential since adverse drug reactions (ADRs) are a serious health problem and contribute to unnecessary patient burden and hospital admissions. Healthcare professionals have little awareness of pharmacovigilance and ADR reporting, and only few educational interventions had durable effects on this awareness. Our future healthcare providers should therefore acquire an adequate set of pharmacovigilance competencies to rationally prescribe, distribute, and monitor drugs. We investigated the pharmacovigilance and ADR-reporting competencies of healthcare students to identify educational interventions that are effective in promoting pharmacovigilance.

METHODS

The PubMed, EMBASE, Cochrane, CINAHL, PsycINFO, and ERIC databases were searched using the terms "pharmacovigilance," "students," and "education.".

RESULTS

Twenty-five cross-sectional and 14 intervention studies describing mostly medical and pharmacy students were included. Intentions and attitudes on ADR reporting were overall positive, although most students felt inadequately prepared, missed the training on this topic, and lacked basic knowledge. Although nearly all students observed ADRs during clinical rounds, only a few had actually been involved in reporting an ADR. Educational interventions were predominately lectures, sometimes accompanied by small interactive working groups. Most interventions resulted in a direct increase in knowledge with an unknown long-term effect. Real-life learning initiatives have shown that healthcare students are capable of contributing to patient care while increasing their ADR-reporting skills and knowledge.

CONCLUSIONS

There is an urgent need to improve and innovate current pharmacovigilance education for undergraduate healthcare students. By offering real-life pharmacovigilance training, students will increase their knowledge and awareness but can also assist current healthcare professionals to meet their pharmacovigilance obligations.

Stem Cell Research and Clinical Translation: A Roadmap about Good Clinical Practice and Patient Care

The latest research achievements in the field of stem cells led in 2016 to the publication of “Guidelines for Stem Cell Research and Clinical Translation” by the International Society for Stem Cell Research (ISSCR). Updating the topics covered in previous publications, the new recommendations offer interesting ethical and scientific insights. Under the common principles of research integrity, protection of patient's welfare, respect for the research subjects, transparency and social justice, the centrality of good clinical practice, and informed consent in research and translational medicine is supported. The guidelines implement the abovementioned publications, requiring rigor in all areas of research, promoting the validity of the scientific activity results and emphasizing the need for an accurate and efficient public communication. This paper aims to analyze the aforementioned guidelines in order to provide a valid interpretive tool for experts. In particular, a research activity focused on the bioethical, scientific, and social implications of the new recommendations is carried out in order to provide food for thought. Finally, as an emerging issue of potential impact of current guidelines, an overview on implications of compensation for egg donation is offered.
