Abstract
Introduction Drug trials in neonates are scarce, and the neonates may consequently be at risk of adverse drug reactions (ADRs). Spontaneous ADR reporting is an important tool for expanding the knowledge on drug safety in neonates. This study explores the quality of current neonatal ADR reports and the ADR reports of the most common drugs used in neonatal departments. Methods An observational cross-sectional study focused on neonates was conducted using data on spontaneous reports extracted from the U.S. Food and Drug Administration Adverse Events Reporting System (FAERS) from the third quarter of 2014 up to December 2022. Only the primary suspect drugs given to neonates or subjects aged <30 days were included in the analysis. Results Spontaneous reports from 13 million patients of all ages, totaling 50 million ADRs, were evaluated. Information regarding the age was missing in 40% of the reports, and data on 43,737 neonates with 948 different suspected drugs were identified and included in the analysis. We report the frequency of spontaneous ADR reports in the FAERS database for the ten most frequently administered drugs in neonatal intensive care units in the USA. Conclusion Overall, neonatal ADRs are still underreported. The FAERS database in its current form discriminates insufficiently between prenatal and postnatal drug exposures. Hence, improved neonatal pharmacovigilance systems are urgently needed.

Educational interventions in pharmacovigilance to improve the knowledge, attitude and the report of adverse drug reactions in healthcare professionals: Systematic Review and Meta-analysis. Daru 2024; 32:421-434. [PMID: 38427161 PMCID: PMC11087385 DOI: 10.1007/s40199-024-00508-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 02/15/2024] [Indexed: 03/02/2024] Open
Abstract
OBJECTIVES Underreporting of adverse drug reactions (ADRs) limits and delays the detection of signs. The aim of this systematic review with meta-analyses was to synthesize the evidence of educational interventions (EIs) efficacy in health professionals to increase ADR reporting, attitudes, and knowledge of pharmacovigilance. EVIDENCE ACQUISITION A systematic literature review was carried out to identify randomized clinical trials evaluating the efficacy of EI in pharmacovigilance in health professionals to improve ADR reports, knowledge, and attitude toward pharmacovigilance. ADR reports were pooled by calculating Odds Ratio (OR) with a 95% confidence interval (95%CI), while pharmacovigilance knowledge and attitude were pooled by calculating a mean difference (MD) with 95%CI. In addition, the subanalysis was performed by EI type. Meta-analysis was performed with RevMan 5.4 software. PROSPERO registry CRD42021254270. RESULTS Eight hundred seventy-five articles were identified as potentially relevant, and 11 were included in the systematic review. Metanalysis showed that EI increased ADR reporting in comparison with control group (OR = 4.74, [95%CI, 2.46 to 9.12], I2 = 93%, 5 studies). In subgroup analysis, the workshops (OR = 6.26, [95%CI, 4.03 to 9.73], I2 = 57%, 3 studies) increased ADR reporting more than telephone-based interventions (OR = 2.59, [95%CI, 0.77 to 8.73], I2 = 29%, 2 studies) or combined interventions (OR = 5.14, [95%CI, 0.97 to 27.26], I2 = 93%, 3 studies). No difference was observed in pharmacovigilance knowledge. However, the subanalysis revealed that workshops increase pharmacovigilance knowledge (SMD = 1.85 [95%CI, 1.44 to 2.27], 1 study). Only one study evaluated ADR reporting attitude among participants and showed a positive effect after the intervention. CONCLUSION EI improves ADR reports and increases pharmacovigilance knowledge. Workshops are the most effective EI to increase ADR reporting.

Abstract
BACKGROUND Understanding knowledge and attitudes of health care professionals (HCPs) towards adverse drug reaction (ADR) reporting can inform educational interventions promoting ADR reporting. OBJECTIVE To explore knowledge, attitudes, practice, and barriers of local HCPs towards ADR reporting. METHODS Focus groups involving HCPs from different settings were organized to help develop a questionnaire. The questionnaire was validated and disseminated to pharmacists, physicians, dentists and nurses practicing in Malta. A review of ADR reports reported in Malta from 2004 to 2021 was carried out to contextualise questionnaire findings. RESULTS Overall, HCPs (n = 374) had good knowledge on pharmacovigilance and a positive attitude towards ADR reporting however nurses were found to be less knowledgeable than physicians, dentists, and pharmacists. The main barrier for not reporting ADRs was difficulty to understand whether an adverse event occurred (n = 187). A total of 2581 ADR reports were reported in Malta. Among HCPs, physicians and dentists reported most ADRs (1060 reports), followed by pharmacists (307 reports) and nurses (257 reports). CONCLUSION Further ADR educational and promotional efforts are needed to increase awareness on the importance of quality ADR reporting and increase the number of ADR reports reported by local HCPs.

Data-Driven Identification of Factors That Influence the Quality of Adverse Event Reports: 15-Year Interpretable Machine Learning and Time-Series Analyses of VigiBase and QUEST. JMIR Med Inform 2024; 12:e49643. [PMID: 38568722 PMCID: PMC11024759 DOI: 10.2196/49643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 10/10/2023] [Accepted: 02/24/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND The completeness of adverse event (AE) reports, crucial for assessing putative causal relationships, is measured using the vigiGrade completeness score in VigiBase, the World Health Organization global database of reported potential AEs. Malaysian reports have surpassed the global average score (approximately 0.44), achieving a 5-year average of 0.79 (SD 0.23) as of 2019 and approaching the benchmark for well-documented reports (0.80). However, the contributing factors to this relatively high report completeness score remain unexplored. OBJECTIVE This study aims to explore the main drivers influencing the completeness of Malaysian AE reports in VigiBase over a 15-year period using vigiGrade. A secondary objective was to understand the strategic measures taken by the Malaysian authorities leading to enhanced report completeness across different time frames. METHODS We analyzed 132,738 Malaysian reports (2005-2019) recorded in VigiBase up to February 2021 split into historical International Drug Information System (INTDIS; n=63,943, 48.17% in 2005-2016) and newer E2B (n=68,795, 51.83% in 2015-2019) format subsets. For machine learning analyses, we performed a 2-stage feature selection followed by a random forest classifier to identify the top features predicting well-documented reports. We subsequently applied tree Shapley additive explanations to examine the magnitude, prevalence, and direction of feature effects. In addition, we conducted time-series analyses to evaluate chronological trends and potential influences of key interventions on reporting quality. RESULTS Among the analyzed reports, 42.84% (56,877/132,738) were well documented, with an increase of 65.37% (53,929/82,497) since 2015. Over two-thirds (46,186/68,795, 67.14%) of the Malaysian E2B reports were well documented compared to INTDIS reports at 16.72% (10,691/63,943). For INTDIS reports, higher pharmacovigilance center staffing was the primary feature positively associated with being well documented. In recent E2B reports, the top positive features included reaction abated upon drug dechallenge, reaction onset or drug use duration of <1 week, dosing interval of <1 day, reports from public specialist hospitals, reports by pharmacists, and reaction duration between 1 and 6 days. In contrast, reports from product registration holders and other health care professionals and reactions involving product substitution issues negatively affected the quality of E2B reports. Multifaceted strategies and interventions comprising policy changes, continuity of education, and human resource development laid the groundwork for AE reporting in Malaysia, whereas advancements in technological infrastructure, pharmacovigilance databases, and reporting tools concurred with increases in both the quantity and quality of AE reports. CONCLUSIONS Through interpretable machine learning and time-series analyses, this study identified key features that positively or negatively influence the completeness of Malaysian AE reports and unveiled how Malaysia has developed its pharmacovigilance capacity via multifaceted strategies and interventions. These findings will guide future work in enhancing pharmacovigilance and public health.

BMJ Open 2023; 13:e071079. [PMID: 37709326 PMCID: PMC10503375 DOI: 10.1136/bmjopen-2022-071079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 07/27/2023] [Indexed: 09/16/2023] Open
Abstract
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.

Abstract
PURPOSE Spontaneous notification systems are essential in a post-marketing safety context. However, using this method, only about 6% of all adverse drug reactions are notified. To overcome this sub-notification problem, new methods need to be developed to improve and facilitate reporting. In this sense, the use of digital media, mainly medical mobile apps, has been presented as a powerful tool, including in pharmacovigilance. We performed a scope review to identify the available apps used to report adverse drug reactions around the world to eventually identify which of them best fits the Portuguese pharmacovigilance system. METHODS The Joanna Briggs Institute guidelines were considered, and the framework proposed by Arksey and O'Malley was followed. All the articles that met the inclusion criteria were examined for this review. When the studies lacked in information about the app, Google was used to enhance the search for further information. RESULTS A final number of five articles were included, revealing seven implemented mobile apps for adverse drug reaction report (Medwatcher, VigiBIP, Yellow Card, Bijwerking, Halmed, Med Safety, and ADR PvPi). These apps are implemented in the United States, France, United Kingdom, The Netherlands, Croatia, and India. Med Safety was originally designed for multi-region use and is implemented in 12 low and middle-income countries. CONCLUSIONS Apps are easier and faster ways of reporting. The integration of such a tool in an individual care plan would allow to maintain a complete electronic health record at both individual and global level and could be eventually seen as an added value by both health professionals and patients. A country specific version of the WEB-RADR could be a solution for Portugal, in order to introduce an app to notify ADRs at the national level, due previous successful experiences in European countries.

Abstract
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.

Abstract
BACKGROUND Evaluating a pharmacovigilance system helps identify its deficiencies and could facilitate measures to remedy and improve the quantity and quality of adverse drug reaction (ADR) reports and other opportunities for pharmacovigilance systems strengthening. This study aimed to evaluate the status of pharmacovigilance in Iran using the World Health Organization (WHO) pharmacovigilance indicators with the prospect of identifying the gaps and areas for improvement. METHODS This study was conducted in 2 parts. The first part included a secondary analysis of the national data obtained from the Iranian National Pharmacovigilance Center (PVC) using a structured data collection form based on WHO core pharmacovigilance indicators. In the second part, a 3-month prospective study was carried out to investigate 2 outcome indicators, ie, length of stay and costs of medicine-related hospitalization in all patients of 2 main referral hospitals in the southeast and north of Iran. RESULTS Iran has a PVC with national policy, trained staff, and a statutory budget. In 2017, the number of ADR reports was 15.0 per 100 000 population, and 262 signals were detected during the preceding 5 years. The average length of stay and costs of medicine-related hospitalization were 5 days and US$817.2 in Afzalipour hospital and 6.6 days and US$306.7 in Razi hospital, respectively. The status of pharmacovigilance in the Iranian public health programs (PHPs) is unknown, and most of the indicators could not be assessed. CONCLUSION A robust pharmacovigilance system is a pivotal part of the overall medicines regulatory system. The Iranian pharmacovigilance system has relatively the proper structural condition. Though the underreporting of ADRs, especially medicine-related deaths, is an important issue, and some indicators' status was unclear. The Iranian pharmacovigilance program requires a higher prioritization, particularly in the PHPs, a greater allocation of resources, and cross-sectoral cooperation to bolster and achieve the pharmacovigilance objectives.

Abstract
A quantitative descriptive study based on Brazilian Active Pharmacovigilance of Dolutegravir (DTG) Project was performed to describe the adverse drug reactions (ADRs) to DTG reported and to evaluate the noncompleteness of data from DTG active pharmacovigilance in Brazil. ADRs and clinical and individual data were obtained from information from the Pharmacovigilance Questionnaire from April 2017 to August 2019. The reported ADRs were classified using the Medical Dictionary for Regulatory Activities (MedDRA). In the evaluated period, 249,066 individuals using DTG participated in the active pharmacovigilance of DTG, with 3472 (1.39%) reporting ADRs at least once. A total of 6312 ADRs were reported, of which 57.56% were persistent and 81.46% were not serious according to the individuals' reports. Most of the reported ADRs were gastrointestinal, neurological and psychiatric. ADRs related to neural tube defects and serious neuropsychiatric ADRs have been reported. Completion of more than half of the fields in the Pharmacovigilance Questionnaire was excellent. The frequency of ADR was low in relation to the number of people living with HIV (PLHIV) using DTG in Brazil, which suggests good tolerability and safety of DTG. The DTG active pharmacovigilance database in Brazil showed good data completeness.

J Clin Pharm Ther 2022; 47:1240-1248. [PMID: 35362208 DOI: 10.1111/jcpt.13661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 03/10/2022] [Accepted: 03/23/2022] [Indexed: 11/28/2022]
Abstract
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.

Changes in suspected adverse drug reaction reporting via the Yellow Card scheme in Wales following the introduction of a National Reporting Indicator. Br J Clin Pharmacol 2022; 88:3829-3836. [PMID: 35322450 PMCID: PMC9544666 DOI: 10.1111/bcp.15326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 02/09/2022] [Accepted: 03/14/2022] [Indexed: 11/17/2022] Open
Abstract
Aims This study aimed to assess the impact of a National Reporting Indicator (NRI) on rates of reporting of suspected adverse drug reactions using the Yellow Card scheme following the introduction of the NRI in Wales (UK) in April 2014. Methods Yellow Card reporting data for general practitioners and other reporting groups in Wales and England for the financial years 2014–15 (study period 1) and 2015–16 (study period 2) were obtained from the Medicines and Healthcare Products Regulatory Agency and compared with those for 2013–14 (pre‐NRI control period). Results The numbers of Yellow Cards submitted by general practitioners in Wales were 271, 665 and 870 in the control period, study period 1 and study period 2, respectively. This is equivalent to an increase of 145% in study period 1 and 221% in study period 2 compared with the 12‐month control period (2013–14). Corresponding increases in England were 17% and 37%, respectively (P < .001 chi–squared test). The numbers of Yellow Cards submitted by other groups in Wales were 906, 795 and 947 in each of the study periods. Conclusions Introduction of the NRI corresponded with a significant increase in the number of Yellow Cards submitted by general practitioners in Wales. General practitioner reporting rates continued to increase year on year through to 2018–19 with the NRI still in place. No concomitant change was found in reporting rates by other groups in the health boards in Wales.

JMIR Form Res 2022; 6:e37605. [PMID: 36206034 PMCID: PMC9587488 DOI: 10.2196/37605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 08/02/2022] [Accepted: 08/17/2022] [Indexed: 11/23/2022] Open
Abstract
Background Medicine use is the most common intervention in health care. The frequency with which medicines are used means medication-related problems are very common. One common type of medication-related problems is adverse drug events, which are unintended and harmful effects associated with use of medicines. Reporting of adverse drug events to regulatory authorities is important for evaluation of safety of medicines; however, these adverse effects are frequently unreported due to various factors, including lack of consumer-friendly reporting tools. Objective The aim of this study was to develop a user-friendly digital tool for consumers to report medication-related adverse effects. Methods The project consisted of 3 parts: (1) content development, including a systematic literature search; (2) iterative system development; and (3) usability testing. The project was guided by participatory design principles, which suggest involving key stakeholders throughout the design process. The first 2 versions were developed as a mobile app and were tested with end users in 2 workshops. The third version was developed as a web application and was tested with consumers who were taking regular medicines. Consumers were asked to complete a modified version of the mHealth app usability questionnaire (MAUQ), an 18-item questionnaire with each item scored using a 7-point Likert scale ranging from 0 (strongly disagree) to 7 (strongly agree). The MAUQ assessed 3 subscales including ease of use (5 items), interface and satisfaction (7 items), and usefulness (6 items). Continuous variables were reported as mean (SD) values, whereas categorical variables were presented as frequencies (percentages). Data analysis was conducted in Microsoft Excel. Results The content for the system was based on a systematic literature search and short-listing of questions, followed by feedback from project team members and consumers. Feedback from consumers in the 2 workshops were incorporated to improve the functionality, visual design, and stability of the third (current) version. The third version of the system was tested with 26 consumers. A total of 79% (N=307/390) of all responses on the MAUQ were scored 6 or 7, indicating that users generally strongly agree with the usability of the system. When looking at the individual domains, the system had an average score of 6.3 (SD 0.9) for “ease of use,” 6.3 (SD 0.8) for “interface and satisfaction,” and 5.2 (SD 1.4) for “usefulness.” Conclusions The web-based system for medicine adverse effects reporting is a user-friendly tool developed using an iterative participatory design approach. Future research includes further improving the system, particularly the usefulness of the system, as well as testing the scalability and performance of the system in practice.

Qualitative Study of Community Pharmacists' and General Practitioners' Views toward Pharmacovigilance in Lithuania. Healthcare (Basel) 2021; 9:healthcare9081072. [PMID: 34442209 PMCID: PMC8392662 DOI: 10.3390/healthcare9081072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Revised: 08/18/2021] [Accepted: 08/19/2021] [Indexed: 11/16/2022] Open
Abstract
Lithuania is the leader in pharmacovigilance among the three Baltic countries. However, comparisons with other European countries are difficult because the reported number of adverse drug reactions (ADRs) in Lithuania is too low to rely on in terms of the annual use of medicines by the population over the year. The aim of this study was to explore challenges related to the understanding and practices of general practitioners and community pharmacists in reporting ADRs in Lithuania. The qualitative study approach of face-to-face interviews was used. All interviews were recorded, transcribed verbatim, and thematically analyzed. Twelve interviews with general practitioners and community pharmacists were conducted from March 2020 through December 2020. All participants had a basic knowledge of pharmacovigilance, but only four participants reported ADRs to the interviewer. Six main barriers regarding ADR reporting were identified, and appropriate interventions were suggested. The importance of collaboration between physicians and pharmacists was highlighted, and the need for guidelines supporting collaboration was expressed. Medications are becoming more complex, and comprehensive medication management is key for the optimization of patient outcomes. Our results reveal the need to improve and innovate the current pharmacovigilance system at all levels, starting from education for pharmacy and healthcare students and continuing through the development of ADR procedures.

Abstract
Background: Interventions for improving reporting and management of adverse drug reactions (ADRs) need regular evaluations of attitude and knowledge of health care professionals regarding pharmacovigilance.Research design and methods: An exploratory survey among general practitioners in Germany was conducted.Results: We interviewed 302 individuals (participation rate 34.3%; mean age 54 yrs; 37.1% female). Underreporting was prevalent in the sample (only 16.6% had reported an ADR in 2015; average total number of ADR-reports was 5). We found awareness of the importance of pharmacovigilance and ADRs, information deficits (43% were not aware of the obligation to report ADRs), and several uncertainties regarding the detection and reporting of ADRs. The participants rated the German ADR reporting system as satisfactory (mean grade 3.7 ± 1.2) and criticized the expenditure of time (63.6%) and the overall complexity (47.4%). To increase the motivation to report ADRs, the majority requested the possibility to report by telephone (61.3%), feedback after reporting (49.3%), telephone consultations (47.4%), and more education and training in pharmacovigilance (31.1%), also during medical school (25.8%).Conclusions: We found evidence of objective and subjective need for further (mandatory) education and training in pharmacovigilance, already during medical school. Our results point to some shortcomings of the German pharmacovigilance system.

Abstract
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.

Abstract
PROPOSE Underreporting of Adverse Drug Reactions (ADRs) reduces the sensitivity of pharmacovigilance systems. We described ADR reporting and its trend from 1999 to 2017 and estimated the ADR underreporting in the Iranian Pharmacovigilance Center. METHODS We expressed the number of ADR reporting per inhabitants and admissions and their possible trends. Finally, ADR underreporting percentages were estimated by three approaches: prospective studies, literature review, stratification of the country; and the trend of the proportion of ADR per inhabitants was corrected. RESULTS The proportion of ADR reporting was 15.3 per 100 000 inhabitants (95% CI: 15.2, 15.8) and 10.0 per 100 000 admissions (95% CI: 9.8, 10.2) in 2017, and its trend was increasing with 16.3% average change per annum during 19 years. The median of estimated percentages of underreporting was 76.0% (IQR: 64.32-81.35). After the correction, the mean proportion of ADR reporting for 19 years reached from 5.87 to 10.33 per 100 000 inhabitants. CONCLUSIONS The trend of ADRs reporting has been increasing over the 19 years but is still low. This study showed a considerable underreporting of ADR, and about one of four detected ADRs were reported to the pharmacovigilance center from 1999 to 2017.
