Development, assessment and educational impact of a blended e-learning training program on pharmacovigilance implemented in four African countries.

Introduction: Efforts to improve medication access in low-and middle-income countries, particularly in Sub-Saharan Africa, have made progress, especially in the fight against infectious diseases such as tuberculosis. However, challenges exist in establishing effective pharmacovigilance systems. The PhArmacoVIgilance Africa (PAVIA) project was committed to enhancing pharmacovigilance in Tanzania, Eswatini, Nigeria, and Ethiopia, with an emphasis on anti-tuberculosis drugs, utilizing various methods, including training. This study evaluates the PAVIA training program's effectiveness and its adaptation during the COVID-19 pandemic. Methods: A blended e-learning program, incorporating two courses and a platform for educational materials, was developed. This program, designed to train healthcare professionals in pharmacovigilance, was incorporated into a Training of Trainers model. To evaluate the program effectiveness, we used multiple measures such as assessing knowledge gain through pre-and post-test scores, assessing learners' satisfaction and attitudes via questionnaires, and analyzing Individual Case Safety Reports (ICSRs) in VigiBase to determine the impact on spontaneous reporting systems in the PAVIA countries. Results: 121 learners enrolled in the pilot trainings, including 36 from Tanzania, 34 from Eswatini, 25 from Nigeria, and 26 from Ethiopia. Notably, post-test scores were significantly higher than pre-test scores in all four countries. Following the pilot trainings, multiple step-down training sessions were held in Tanzania, Eswatini, and Nigeria, with a total of 827 learners registering and 421 successfully completing the program. Learners' scores on the post-tests were significantly higher than on the pre-tests for both courses in all three countries. Learners' feedback on the training was overwhelmingly positive. Additionally, a qualitative analysis of ICSRs revealed a substantial increase in reports after the training in Tanzania, Eswatini, and Nigeria. Discussion: An innovative e-learning program trained healthcare professionals in pharmacovigilance and anti-tuberculosis drug safety over 3 years in four PAVIA countries. The program effectively improved participants' knowledge, received positive feedback, and likely had an impact on reporting rates in Tanzania, Eswatini, and Nigeria, although a direct causal link could not be definitively established due to data limitations and other factors, such as the heightened reporting rates associated with COVID-19 vaccines, that could have contributed to the notable increase in ICSRs.

Funding and financial sustainability of pharmacovigilance: suggested models for funding pharmacovigilance in resource-limited African countries.

Background: An important factor hindering the growth of pharmacovigilance (PV) in resource-limited settings is the lack of adequate funds to establish a functional National Pharmacovigilance System. Consequently, the crucial function of monitoring and ensuring the availability of safe medicines in these settings cannot be guaranteed considering the peculiarities of diseases and medicines used. Objectives: The objective of this paper is to provide an overview as to the availability of potential sources of funds, which could be explored to ensure Medicine Safety and to proffer a potential framework likely to ensure sustainable funding of PV in Africa. Methods/processes: The process of developing this framework entailed a review of PV financing in some developed economies, a landscape study of funding of PV in some African countries, an in-depth understanding of the PV system and the organisational structure and nexus between the regulatory agencies and National Pharmacovigilance Centre. Critical points for consideration included the sources of funds, revenue pool, the disbursement of funds, budgeting and expenditure profile and the legal framework. Consultative meetings, webinars and interviews with experts were carried out. Results: The findings showed that most of the PV systems were mainly integrated into the regulatory agencies regarding operational and fiscal governance with few facilities being independent of the regulatory agencies. The main source of funding was from the government with significant donor funding which is ad hoc and non-sustainable. Several potential sources were identified but yet to be exploited. There were no legal provisions for PV financing. A framework likely to ensure sustainable PV financing is suggested to capture all available sources of funding, mine the potential sources providing a sizeable pool of revenue to address its activities and enabling legal framework which will engender autonomy. Furthermore, it will address the nexus between the regulatory agencies and the PV outfits, thus enabling appropriate share of resources and blockage of diversions. Conclusion: In all, addressing the various elements identified in this study and providing the legal provisions which guarantees some degree of autonomy will provide a sustainable mechanism for PV funding in the resource-limited setting of Africa.

Funding models for pharmacovigilance in resource-limited African countries An important factor hindering the growth of pharmacovigilance (PV) in resource-limited settings following their entry into the WHO Programme of International Drug Monitoring is the lack of adequate funds to establish a functional National Pharmacovigilance System. This article provides an overview of various potential sources of funds in these settings and how they can be harnessed to fund PV. We undertook a review of PV financing in developed settings and carried out a landscape study of funding of PV in some African countries, as well as having an in-depth understanding of the PV system and the organisational structure. The nexus between the regulatory agencies and National Pharmacovigilance Centre was noted. We took into account the sources of funds, revenue pool, the disbursement of funds, budgeting and expenditure profile and the legal framework for the different African countries. We also identified the prevalent and potential sources of funds for PV. Consultative meetings, webinars and interviews with experts in PV were carried out as well. We discovered that most of the PV facilities were mainly integrated into the regulatory agencies regarding operational and fiscal governance with few facilities being independent of the regulatory agencies. The main source of funding was from the government with significant donor funding which is ad hoc and non-sustainable. Several potential sources were identified but yet to be exploited. There were no legal provisions for PV financing. We have now proposed funding models that may lead to increased revenue for PV in these countries as well as suggesting that a legal framework be provided to guarantee sustainability and address the nexus between the regulatory agencies and the PV outfits to ensure an appropriate share of resources and blocking diversions.

An evaluation of postmarketing reports of hyperglycaemia associated with dolutegravir for treatment of HIV in Eswatini.

BACKGROUND: Dolutegravir (DTG) is an Integrase Strand Transfer Inhibitor (INSTI) indicated in combination with other antiretroviral agents for the treatment of HIV infection. It is available in a number of pharmaceutical preparations including the fixed-dose combination (TLD) containing tenofovir (300 mg) + lamivudine (300 mg) + dolutegravir (50 mg). In 2018, Eswatini adopted TLD as the preferred first-line HIV treatment regimen for adults and adolescents as per WHO recommendations. From March 2019 to March 2020, the National Pharmacovigilance Center (NPC) in Eswatini received 8 reports of hyperglycaemia associated with the use of DTG. This study was conducted to investigate if Eswatini NPC database included cases suggestive of causality between dolutegravir and hyperglycaemia. METHOD: A qualitative synthesis of information from the Eswatini national pharmacovigilance database from March 2019 to March 2020 was conducted to investigate a casual association between hyperglycaemia and dolutegravir. RESULTS: All reports with dolutegravir containing regimen and suspected Adverse Event of hyperglycaemia in the period of March 2019 to March 2020 were included in the study. Seven of the reports were serious (resulted in hospitalization and one case concerned optic neuritis, leading to blindness). Two patients had a medical history of diabetes while the rest of the patients had never experienced hyperglycaemia before starting dolutegravir. For all the reports, the time to onset of hyperglycaemia ranges from 2-5 months after the initiation of DTG. None of the patients discontinued the use of DTG. All the patients were treated with oral hypoglycaemic medication. In severe cases, patients were treated with intravenous normal saline and ringer lactate as well as rapid-acting insulins. All patients are currently stable on oral hypoglycaemic drugs. CONCLUSION: Cases that support causality between dolutegravir containing regimen and hyperglycaemia were found. These cases were mainly serious. Based on these findings it is recommended that healthcare professionals (HCPs) actively screen all patients for risk factors of hyperglycaemia before DTG initiation. In addition, it is important that HCPs are aware of the possible association between DTG and hyperglycaemia.

Development of a multivariate prediction model to identify individual case safety reports which require clinical review.

BACKGROUND: The number of Individual Case Safety Reports (ICSRs) in pharmacovigilance databases are rapidly increasing world-wide. The majority of ICSRs at the Netherlands Pharmacovigilance Centre Lareb is reviewed manually to identify potential signal triggering reports (PSTR) or ICSRs which need further clinical assessment for other reasons. OBJECTIVES: To develop a prediction model to identify ICSRs that require clinical review, including PSTRs. Secondly, to identify the most important features of these reports. METHODS: All ICSRs (n = 30 424) received by Lareb between October 1, 2017 and February 26, 2021 were included. ICSRs originating from marketing authorisation holders and ICSRs reported on vaccines were excluded. The outcome was defined as PSTR (yes/no), where PSTR 'yes' was defined as an ICSR discussed at a signal detection meeting. Nineteen features were included, concerning structured information on: patients, adverse drug reactions (ADR) or drugs. Data were divided into a training (70%) and test set (30%) using a stratified split to maintain the PSTR/no PSTR ratio. Logistic regression, elastic net logistic regression and eXtreme Gradient Boosting models were trained and tuned on a training set. Random down-sampling of negative controls was applied on the training set to adjust for the imbalanced dataset. Final models were evaluated on the test set. Model performances were assessed using the area under the curve (AUC) with 95% confidence interval of a receiver operating characteristic (ROC), and specificity and precision were assessed at a threshold for perfect sensitivity (100%, to not miss any PSTRs). Feature importance plots were inspected and a selection of features was used to re-train and test model performances with fewer features. RESULTS: 1439 (4.7%) of reports were PSTR. All three models performed equally with a highest AUC of 0.75 (0.73-0.77). Despite moderate model performances, specificity (5%) and precision (5%) were low. Most important features were: 'absence of ADR in the Summary of product characteristics', 'ADR reported as serious', 'ADR labelled as an important medical event', 'ADR reported by physician' and 'positive rechallenge'. Model performances were similar when using only nine of the most important features. CONCLUSIONS: We developed a prediction model with moderate performances to identify PSTRs with nine commonly available features. Optimisation of the model using more ICSR information (e.g., free text fields) to increase model precision is required before implementation.

Development and validation of a machine-learning algorithm to predict the relevance of scientific articles within the field of teratology.

The Dutch Teratology Information Service Lareb counsels healthcare professionals and patients about medication use during pregnancy and lactation. To keep the evidence up to date, employees perform a standardized weekly PubMed query where relevant literature is identified manually. We aimed to develop an accurate machine-learning algorithm to predict the relevance of PubMed entries, thereby reducing the labor-intensive task of manually screening the articles. We fine-tuned a pre-trained natural language processing transformer model to identify relevant entries. We split 15,540 labeled entries into case-control-balanced train, validation, and test datasets. Additionally, we externally validated the model prospectively with 1288 labeled entries obtained from weekly queries after developing the model. This dataset was also independently labeled by a team of six experienced human raters to evaluate our model's performance. The validation of our machine learning model on the retrospectively collected outheld dataset obtained an area under the sensitivity-versus-specificity curve of 89.3 % (CI: 88.2- 90.4). In the prospective external validation of the model, our model classified relevant literature with a sensitivity versus specificity curve area of 87.4 % (CI: 85.0-89.8). Our model achieved a higher sensitivity than the human raters' team without sacrificing too much specificity. The team of human raters showed weak to moderate levels of agreement in their article classifications (kappa range 0.40-0.64). The human selection of the latest relevant literature is indispensable to keep the teratology information up to date. We show that automatic preselection of relevant abstracts using machine learning is possible without sacrificing the selection performance.

Factors Contributing to Best Practices for Patient Involvement in Pharmacovigilance in Europe: A Stakeholder Analysis.

INTRODUCTION: Involving patients in decision making adds value in the context of pharmacovigilance (PV). This added value goes beyond participation in spontaneous reporting systems for adverse drug reactions. However, there is a gap between allowing patients to report and actual patient involvement. Views regarding best practices from regulators, patient organizations and pharmaceutical companies could help increase and improve patient involvement in PV. OBJECTIVE: The aim of this study was to investigate the factors contributing to best practices for patient involvement in PV and to develop a definition of patient involvement based on a qualitative multistakeholder study across Europe. METHODS: A literature review was conducted to map the field of study and obtain insights for the elaboration of an interview guide. Subsequently, patient representatives, members of the pharmaceutical industry and regulators were invited to participate in interviews. These interviews were analyzed using NVIVO® software and employing reflective thematic analysis. RESULTS: A total of 20 interviews were conducted with representatives at both the national and European levels. The best practices identified were engagement from the start, face-to-face communication, a full circle of feedback, same-level partners, structured involvement and guidelines, establishing common goals, patient education and empowerment, and developing trust and balance. These activities can be implemented via deep collaboration among stakeholders. A definition of patient involvement was constructed in accordance with the input of all stakeholder groups, which reflects the involvement of all types of patients at all levels of the decision-making process. CONCLUSION: In this study, we developed a definition for patient involvement based on qualitative interviews. The factors contributing to best practices for patient involvement were mentioned across stakeholder groups and aimed to stimulate patient involvement in PV. Patients are eager to become equal partners and to engage effortlessly in the same manner as other stakeholders.

COVID-19 vaccine reactogenicity - A cohort event monitoring study in the Netherlands using patient reported outcomes.

OBJECTIVES: To explore factors that are associated with reactogenicity in general and systemic after the first dose of COVID-19 vaccine in the Netherlands. DESIGN: A web-based prospective cohort design using patient reported outcomes (PROs). SETTING: Any person who has been vaccinated with any brand of COVID-19 vaccine in the Dutch COVID immunization programme. PARTICIPANTS: 22,184 participants. Of these, 13,959 (62.9%) experienced reactogenicity in general and 11,979 (54.0%) systemic reactogenicity within 7 days after vaccination. MAIN OUTCOME MEASURES: Factors that are associated with the occurrence of reactogenicity after COVID-19 vaccination. RESULTS: Compared to the Comirnaty® vaccine, the highest odds ratio (OR) for developing reactogenicity was for the Vaxzevria® vaccine (OR 5.18) followed by Spikevax® (OR 2.16), and Janssen (OR 1.65). Participants with a history of COVID-19 disease had a 3.10 increased odds for reactogenicity. Women had a 2.08 increased odds compared to men. Older participants experienced less reactogenicity. Compared to the age group < 50, the ORs for the age groups 50-60, 61-79, and ≥80 were 0.36, 0.15, and 0.10 respectively. The use of an antipyretic drug, or a drug for nervous system disorders gave an increased odds of 1.34 and 1.16 respectively. A body mass index of 25.0-29.9 and over 30 was negatively associated with reactogenicity (OR 0.87 and OR 0.72 respectively). Comorbidities that were associated with reactogenicity were cardiac disorders (OR 1.26), respiratory disorders (OR 1.31), psychiatric disorders (1.37), reproductive disorders (OR 1.54), and eye disorders (OR 1.55). The factors associated with systemic reactogenicity were mostly comparable, but there were differences for comorbidities, drug use, and the strength of the regression coefficient. CONCLUSIONS: This extensive study with over 22,000 vaccine recipients in the Netherlands demonstrated that, taken into account all factors in the model, the Comirnaty® vaccine gave the least and the Vaxzevria® vaccine the most reactogenicity in general and systemic after the first dose. Also a person with a history of COVID-19 disease, female sex and younger age had an increased odds for experiencing reactogenicity after vaccination.

Pharmacovigilance Data as a Trigger to Identify Antimicrobial Resistance and Inappropriate Use of Antibiotics: A Study Using Reports from The Netherlands Pharmacovigilance Centre.

(1) Background: Antimicrobial resistance (AMR) requires urgent multidisciplinary solutions, and pharmacovigilance has the potential to strengthen current antimicrobial stewardship strategies. This study aimed to characterize AMR-relevant adverse drug reaction (ADR) reports submitted to The Netherlands Pharmacovigilance Centre; (2) Methods: We carried out a descriptive analysis of ADR reports submitted to Lareb, coded with AMR-relevant MedDRA Preferred Terms (PTs); (3) Results: Between 1998 and January 2019, 252 AMR-relevant ADR reports were submitted to Lareb. The most frequent antibiotics were tobramycin (n = 89; 35%), colistin (n = 30; 11.9%), cipro-floxacin (n = 16; 6.3%), doxycycline (n = 14; 5.5%), and aztreonam (n = 12; 4.8%). The PTs used included off label use (n = 91; 36.1%), drug ineffective (n = 71; 28.2%), product use in unapproved indication (n = 28; 11.1%), pathogen resistance (n = 14; 5.6%), and drug resistance (n = 13; 5.2%). 54% of the reports were on Watch antibiotics and 19% were involved in the Reserve group. In the Watch group, "off label use" and "product use in unapproved indication" were the most frequent PTs and the majority of reports on Reserve antibiotics were coded as "Off label". A sharp increase in the number of reports was observed in the three consecutive years with 21 in 2013, 54 in 2014, and 83 in 2015; (4) Conclusions: In addition to existing AMR monitoring strategies, pharmacovigilance databases can serve as a source of data on suspected resistance and inappropriate use. Future research should explore how these AMR-relevant MedDRA Terms are used in resource-limited settings with less capacity to generate laboratory-confirmed resistance data.

Baseline assessment of pharmacovigilance activities in four sub-Saharan African countries: a perspective on tuberculosis.

BACKGROUND: New medicines have become available for the treatment of drug-resistant tuberculosis (DR-TB) and are introduced in sub-Saharan Africa (SSA) by the national TB programs (NTPs) through special access schemes. Pharmacovigilance is typically the task of national medicines regulatory agencies (NMRAs), but the active drug safety monitoring and management (aDSM) recommended for the new TB medicines and regimens was introduced through the NTPs. We assessed the strengths and challenges of pharmacovigilance systems in Eswatini, Ethiopia, Nigeria and Tanzania, focusing on their capacity to monitor safety of medicines registered and not registered by the NMRAs for the treatment of DR-TB. METHODS: Assessment visits were conducted to all four countries by a multidisciplinary team. We used a pharmacovigilance indicator tool derived from existing tools, interviewed key stakeholders, and visited health facilities where DR-TB patients were treated with new medicines. Assessment results were verified with the local NMRAs and NTPs. RESULTS: Most countries have enabling laws, regulations and guidelines for the conduct of pharmacovigilance by the NMRAs. The relative success of NTP-NMRA collaboration is much influenced by interpersonal relationships between staff. Division of roles and responsibilities is not always clear and leads to duplication and unfulfilled tasks (e.g. causality assessment). The introduction of aDSM has increased awareness among DR-TB healthcare providers. CONCLUSION: aDSM has created awareness about the importance of pharmacovigilance among NTPs. In the future, a push for conducting pharmacovigilance through public health programs seems useful, but this needs to coincide with increased collaboration with between public health programs and NMRAs with clear formulation of roles and responsibilities.

Motives to Report Adverse Drug Reactions to the National Agency: A Survey Study among Healthcare Professionals and Patients in Croatia, The Netherlands, and the UK.

INTRODUCTION: Healthcare professionals (HCPs) and patients have various motives to report adverse drug reactions (ADRs) to their national agency. These motives may differ between countries. OBJECTIVE: The aim of this study was to assess to what extent motives of HCPs and patients to report ADRs differ between countries. METHODS: HCPs and patients from Croatia (HR), The Netherlands (NL), and the UK were asked to complete a web-based survey containing questions regarding demographics and ADR reporting. HCPs and patients could select all motives for reporting that applied to them, with a total of 23 and 24 motives, respectively. Descriptive statistics are presented and Chi-square tests were used to test for differences across the countries, with effect sizes calculated using Cramer's V. RESULTS: In total, 296 HCPs and 423 patients were included (60% and 32% from Croatia, 19% and 44% from NL, and 21% and 24% from the UK, respectively). For most of the motives to report or not to report an ADR, there were no differences between countries. Most HCPs from all countries would be motivated to report an ADR if there was a strong suspicion of causality (89%), if it concerned a severe/serious ADR (86%), and if it concerned an ADR for a new, recently marketed drug (77%). Most patients from all countries agreed that they would report an ADR if it concerned a severe ADR (96%), if the ADR influenced their daily activities (91%), and if they were worried about their own situation (90%). Differences across the countries (p < 0.05 and V ≥ 0.21) were observed for three and four of the HCP and patient motives, respectively. For HCPs, these differences were seen in motives related to legal obligation (65% HR, 24% NL, 38% UK), black triangle medicines (27% HR, 4% NL, 77% UK), and the reporting of well-known ADRs (53% HR, 85% NL, 69% UK). For patients, these differences were seen in motives related to a linkage between the ADR report and the medical notes (59% HR, 60% NL, 30% UK), complexity and time taken to report (25% HR, 13% NL, 40% UK), medicines purchased on the internet (59% HR, 39% NL, 65% UK), and the reporting of embarrassing ADRs (32% HR, 11% NL, 35% UK). CONCLUSIONS: HCPs' and patients' motives to report or not to report ADRs to the national agency were mostly similar across the three countries. Such motives can be used in general strategies to promote and increase ADR reporting. The observed differences provide guidance to further fine-tune ADR reporting at a national level.

Online information discrepancies regarding safety of medicine use during pregnancy and lactation: an IMI ConcePTION study.

Background: Inconsistencies in information on safety of medicine use during pregnancy and lactation can result in sub-optimal treatment for pregnant and lactating women, risks to the fetus or child and unnecessary weaning off breastfeeding. The objective of this study was to analyze information discrepancies regarding medicine use during pregnancy and lactation between on-line sources for patients and health care professionals (HCPs) in four European languages.Research design and methods: The medicines analyzed were ibuprofen, ondansetron, olanzapine, fingolimod, methylphenidate and adalimumab. Recommendations were classified into different data source categories, for patients and for HCPs, and compared between the data source categories for each medicine and language.Results: For patients, 11/24 (46%) and 4/24 (17%) comparisons of the pregnancy and lactation recommendations, respectively, were consistent between all sources. The corresponding figures for HCP-sources were 13/24 (54%) and 5/24 (21%). Regulatory sources had generally more restrictive recommendations. Teratology Information Services (TIS) centers' recommendations for medicine use during pregnancy and lactation were consistent in 25/27 (93%) and 15/22 (68%) of cases respectively.Conclusion: Discrepancies between online information sources regarding medicine use during pregnancy and lactation are common, especially for lactation. TIS centers recommendations were more aligned. Additional work is needed to harmonize information within and between countries to avoid conflicting messages.

Insight in the safety profile of antidiabetic agents glucagon-like peptide-1 agonists and dipeptidyl peptidase-4 inhibitors in daily practice from the patient perspective.

PURPOSE: The primary aim of this study was to gain insight in the safety profile of the new antidiabetic agents glucagon-like peptide-1 (GLP-1) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors in daily practice. The secondary aim was to compare reported adverse drug reactions (ADRs) with information described in the Summary of Product Characteristics (SPC) and to generate knowledge about characteristics, like time to onset and outcome of ADRs. This knowledge is important for drug regulators and clinical practice to understand and manage ADRs better. METHODS: A prospective, observational web-based cohort event monitoring study among first-time users of GLP-1 agonists and DPP-4 inhibitors. Patients were recruited through community pharmacies from 2008 to 2016. Participants were invited to complete six web-based questionnaires over a 1-year periods after start of the antidiabetic agent. Questions were posed about patient characteristics, drug use, and ADRs. Data were analyzed using descriptive statistics. RESULTS: Then, 743 patients were included. Also 62% of all GLP-1 agonist users (total n = 119) and 33% of DPP-4 inhibitor users (total n = 624) experienced an ADR. Of the 10 most reported ADRs, for GLP-1 agonist all, and for DPP-4 inhibitors 8 were described in the drug's SPC. For 45 (91%) ADRs, the patients recovered without discontinuation of the GLP-1 agonist and 79 (73%) ADRs without discontinuation of the DPP-4 inhibitor therapy. CONCLUSIONS: This study gives insight in the safety profile and ADR characteristics of the new antidiabetic agents. This study provides important knowledge for healthcare professionals in managing ADRs and can be directly applied in consultations in daily practice.

Evaluation of a Web-Based, 'Purchase Event' Intensive Monitoring Method for Pharmacovigilance of Natural Health Products: Lessons and Insights from Development Work in New Zealand.

INTRODUCTION: Intensive monitoring methods are used in pharmacovigilance for prescription medicines but have not yet been implemented for natural health products (NHPs). OBJECTIVES: Our objective was to assess feasibility issues with a new 'purchase event' intensive monitoring method for pharmacovigilance of NHPs, including pharmacy and NHP purchaser recruitment rates, collection of NHP purchaser key patient identifier information for data linkage and quality and completeness of data. METHODS: For the Ginkgo study, 213 community pharmacies in the Auckland (Aotearoa New Zealand) District Health Board area were invited to participate. Staff in participating pharmacies (n = 3 [1.4%]) recorded ginkgo product sales and gave purchasers a study invitation card (October 2015-January 2016). Ginkgo purchaser participants were emailed links to web-based baseline and follow-up questionnaires about adverse events occurring during/after taking ginkgo. Participating pharmacists and consumers were invited to provide qualitative feedback about the study. For the NHP-Lite study, all NHPs were included for monitoring. Community pharmacies in the Green Cross Health network were invited to participate. Participating pharmacy staff gave all NHP purchasers a study invitation card over a 2-week period (May 2016). NHP purchaser participants were emailed links to web-based baseline, follow-up and feedback questionnaires. RESULTS: Few community pharmacists (Ginkgo study, n = 3; NHP-Lite study, n = 18) and NHP purchasers (Ginkgo study, n = 0; NHP-Lite study, n = 4) participated. Pharmacists (Ginkgo study, 3/3; NHP-Lite study, 11/18) described several reasons for participating and suggested ways to increase consumer recruitment, including simplifying study procedures. CONCLUSIONS: These web-based, purchase event, intensive monitoring studies, with cohorts built through NHP purchases in pharmacies, identified substantial issues with recruiting pharmacists/pharmacies and NHP purchasers that, at present, render such studies unfeasible. Future studies need to consider other methods of recruiting NHP purchasers and develop a simple method for recording NHP purchases.

Communicating Adverse Drug Reaction Insights Through Patient Organizations: Experiences from a Pilot Study in the Netherlands.

INTRODUCTION: To improve therapeutic decision making, it is crucial that information regarding adverse drug reactions reaches patients. It is not enough to disseminate such findings through regulatory and scientific channels; targeted efforts to reach patients are necessary. One possible avenue is to collaborate with patient organizations. OBJECTIVES: The aim of this pilot study was to explore how adverse drug reactions can be communicated through patient organizations. METHODS: A text describing a signal of levothyroxine and panic attacks was tailored to patients' needs, in terms of language, style and content, with emphasis placed on what to do when experiencing the symptoms described. The signal was communicated via the Dutch thyroid organization's digital newsletter, social media channels, website and print magazine. RESULTS: The digital newsletter was distributed to around 5000 subscribers. On Facebook, 13,820 people viewed the message, with 2346 clicks in the message, indicating an intention to read the whole post. The interactions on social media were positive, and the tone was respectful. CONCLUSION: Patient organizations can help enable effective communication of adverse drug reactions to a relevant audience. The social media post generated more engagement than other communications from the patient organization, indicating a strong interest in this information. The additional patient experiences that were shared in the comments on social media further strengthened the original signal and its relevance to patients, creating an interesting feedback loop. The favourable experiences in this study support further consideration and exploration of this approach to communicate adverse drug reactions to patients.

Patient preferences and expectation for feedback on adverse drug reaction reports submitted in Ghana.

BACKGROUND: Personalized feedback received for spontaneous adverse drug reaction (ADR) reports serves as motivation for future reporting and the effectiveness of the feedback is dependent on the medium used in delivering the information. OBJECTIVE: Explore expectation for feedback from patients on ADR reports submitted to the National Pharmacovigilance Centre (NPvC) in Ghana and the preferred medium for receiving the feedback information. METHODS: Cross-sectional study using structured questionnaire administered through face-to-face interview from August to September 2016 to patients selected by convenience sampling. Pearson chi-square (§2) or Fisher's exact test was used to determine associations between background variables such as age, gender and level of education. RESULTS: The response rate was 86.7% (n=442). Of the participants interviewed, 96.5% expected to receive feedback for ADR reports submitted. Age and level of education were the two variables significantly associated with patients' expectation for feedback.The preferred medium for receiving feedback in decreasing order of preference were, telephone call (60.4%), mobile phone short messaging services (23.0%), email (8.3%), face-to-face meeting (3.4%), personalized letter (3.4%) and publication in a newsletter (1.4%). CONCLUSION: Patients' expectation for receiving feedback for ADR reports submitted to the NPvC is in line with modern trends in communication. NPvC should explore these alternatives for providing feedback to patients. This study is limited to what patients' expectations and preferences were for receiving feedback on ADR reports submitted, additional study to further explore the type of information patients expect to be contained in the feedback will be useful to National Pharmacovigilance Centres. FUNDING: None declared.

Fifteen years of patient reporting -what have we learned and where are we heading to?

INTRODUCTION: In April 2003, the Netherlands Pharmacovigilance Centre Lareb successfully implemented patient reporting to their spontaneous reporting system. The number of reports by patients rapidly grew, prompting the need to evaluate the value of the patient reporting scheme and to compare experiences with other countries. The aim of this article is to summarize our 15-year experience of working with direct patient reporting in pharmacovigilance and to discuss necessary steps in order to optimize the use of patient reports in the future. AREAS COVERED: This article is based on Lareb studies on patient reporting from 2004 onwards and covers the evolution of the Dutch patient reporting system, the value of patient participation in pharmacovigilance, the impact of patient reporting on the spontaneous reporting system and future steps to strengthen patient reporting. EXPERT OPINION: After 15 years of experience with patient reporting we conclude that patients can add value to pharmacovigilance. We recognize that there is a big leap between allowing patients to report and actual patient involvement in pharmacovigilance. It is our belief that increased patient involvement in pharmacovigilance is a way to improve pharmacovigilance, enhancing the general public's trust in medicines.

Recommendations on the Use of Mobile Applications for the Collection and Communication of Pharmaceutical Product Safety Information: Lessons from IMI WEB-RADR.

Over a period of 3 years, the European Union's Innovative Medicines Initiative WEB-RADR (Recognising Adverse Drug Reactions; https://web-radr.eu/ ) project explored the value of two digital tools for pharmacovigilance (PV): mobile applications (apps) for reporting the adverse effects of drugs and social media data for its contribution to safety signalling. The ultimate intent of WEB-RADR was to provide policy, technical and ethical recommendations on how to develop and implement such digital tools to enhance patient safety. Recommendations relating to the use of mobile apps for PV are summarised in this paper. There is a presumption amongst at least some patients and healthcare professionals that information ought to be accessed and reported from any setting, including mobile apps. WEB-RADR has focused on the use of such technology for reporting suspected adverse drug reactions and for broadcasting safety information to its users, i.e. two-way risk communication. Three apps were developed and publicly launched within Europe as part of the WEB-RADR project and subsequently assessed by a range of stakeholders to determine their value as effective tools for improving patient safety; a fourth generic app was later piloted in two African countries. The recommendations from the development and evaluation of the European apps are presented here with supporting considerations, rationales and caveats as well as suggested areas for further research.

Collaboration between patient and pharmacovigilance organizations to gain insight into adults' experiences with drug use and ADRs for the treatment of ADHD.

BACKGROUND: Patient organizations have good access to patients, which can be of interest in gaining knowledge about patients' experiences with drugs. The aim of this study is to investigate if a collaboration between a pharmacovigilance center and an ADHD patient organization can give more insight in patients' experiences with drug use and ADRs for the treatment of AD(H)D. METHODS: Pharmacovigilance Centre Lareb and ADHD patient organization Impuls & Woortblind created a web-based questionnaire asking about patients' experiences with drug use and ADRs. Patients were approached to participate by e-mail and an open web-link. They were also asked to report ADRs through the official reporting form of Lareb. RESULTS: A total of 1160 patients completed the questionnaire, of which 75.2% of the respondents experienced ADRs and 60.7% discontinued treatment because of an ADR. More than 70% experienced positive effects of their drugs. Additionally, 5.0% of the respondents reported their ADRs to Lareb. CONCLUSIONS: Collaboration with patient organizations provide useful insight into patients' experiences with drug use and ADRs taking into account establishing clear 'rules of engagement'. An active approach to collaborate with patient organizations is a way forward to gain more information about drug use and ADRs in a selective cohort.

Patient preferences and expectation for feedback on adverse drug reaction reports submitted in Ghana

Background: Personalized feedback received for spontaneous adverse drug reaction (ADR) reports serves as motivation for future reporting and the effectiveness of the feedback is dependent on the medium used in delivering the information. Objective: Explore expectation for feedback from patients on ADR reports submitted to the National Pharmacovigilance Centre (NPvC) in Ghana and the preferred medium for receiving the feedback information.Methods: Cross-sectional study using structured questionnaire administered through face-to-face interview from August to September 2016 to patients selected by convenience sampling. Pearson chi-square (Χ2) or Fisher's exact test was used to determine associations between background variables such as age, gender and level of education. Results: The response rate was 86.7% (n=442). Of the participants interviewed, 96.5% expected to receive feedback for ADR reports submitted. Age and level of education were the two variables significantly associated with patients' expectation for feedback. The preferred medium for receiving feedback in decreasing order of preference were, telephone call (60.4%), mobile phone short messaging services (23.0%), email (8.3%), face-to-face meeting (3.4%), personalized letter (3.4%) and publication in a newsletter (1.4%). Conclusion: Patients' expectation for receiving feedback for ADR reports submitted to the NPvC is in line with modern trends in communication. NPvC should explore these alternatives for providing feedback to patients. Thisstudy is limited to what patients' expectations and preferences were for receiving feedback on ADR reports submitted, additional study to further explore the type of information patients expect to be contained in the feedback will be useful to National Pharmacovigilance Centres
