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

Evaluation of pharmacovigilance systems for reporting medication errors in Africa and the role of patients using a mixed-methods approach

BACKGROUND: Reviewing the epidemiological profile of medication errors (MEs) reported by African countries and the systems put in place to report such errors is crucial because reporting plays an important role in improving patient safety. The objectives of this study were to characterize the profile of spontaneously reported MEs submitted by African countries to VigiBase; the World Health Organization (WHO) global database of individual case safety reports, describe systems in place for reporting these errors, and explore the challenges and facilitators for spontaneous reporting and understand the potential role of patients. METHODS: In the present study, we used, a mixed-methods sequential explanatory design involving a quantitative review of ME reports over a 21-year period (1997–2018) and qualitative interviews with employees from African countries that are members of the WHO Program for International Drug Monitoring (WHO PIDM). Descriptive statistics were used to summarize key variables of interest. RESULTS: A total of 4,205 ME reports were submitted by African countries to VigiBase representing 0.4% of all reports in the database. Only 15 countries out of the 37 WHO PIDM members from Africa contributed ME to reports, with 99% (3,874) of them reports originating from Egypt, Morocco, and South Africa. The reasons given for low reporting of MEs were weak healthcare and pharmacovigilance systems, lack of staff capacity at the national centers, illiteracy, language difficulties, and socio-cultural and religious beliefs. Some facilitators suggested by the participants to promote reporting included proactive engagement of patients regarding issues relating to MEs, leveraging on increased technology, benchmarking and mentoring by more experienced national centers. Sixteen of the twenty countries interviewed had systems for reporting MEs integrated into adverse drug reaction reporting with minimal patient involvement in seven of these countries. Patients were not involved in directly reporting MEs in the remaining 13 countries. CONCLUSIONS: MEs are rarely reported through pharmacovigilance systems in African countries with limited patient involvement. The systems are influenced by multifactorial issues some of which are not directly related to healthcare

Reporting of adverse events following immunizations in Ghana–Using disproportionality analysis reporting ratios

Background: Timely reporting of safety information post vaccination is pivotal for the success of any vaccination program. Reports of adverse events following immunization (AEFI) of 6 different vaccinations from Ghana were analysed for signals. Methods: De-identified data from active surveillance for AEFIs after 2009 AH1N1 influenza, yellow fever, meningitis, measles-rubella, pneumococcal-rotavirus and human papilloma virus vaccinations were used. All vaccinations occurred between January 2010 and December 2013. The ten most occurring events for each vaccination were captured and arranged using Medical Dictionary for Regulatory Authorities (MedDRA) Preferred Term (PT) and System Organ Classification (SOC) codes. Adverse event incidence rates were calculated for each vaccine type, and signals were generated using proportional reporting ratios (PRR). Results: A total number of 5,141 reports were analysed ranging from 33 (human papilloma virus) to 1958 (measles-rubella). Between 22% and 55% of all AEFIs per vaccine type were collected on the day of vaccination. For each vaccine type, at least 87% of all reported AEFIs occurred in the first 7 days post-vaccination. Multiple reports were received per vaccine type. For the MR vaccine, urticarial recorded the highest attack rate of 6.6 (95% CI 6.2, 7.1) per 100,000 vaccines. The AEFI with the highest PRR for both human papilloma and measles-rubella vaccines was abdominal pain, recording a PRR of 8.15 (95% CI 3.46, 19.23) and 43.75 (95% CI 17.81, 107.45) respectively. Conclusion: These results underscore the competency of public health systems in sub-Saharan African countries (like Ghana) to identify most frequently occurring and important vaccine related safety issues

Preliminary findings from stimulated spontaneous reporting of adverse drug reactions during COVID-19 pandemic: an experience from Ghana

Background: The novel coronavirus disease 2019 (COVID-19) is an ongoing pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). There is limited information on the safety of drugs used for the treatment of COVID-19.Objective: Objective of this study is to describe the pattern of stimulated spontaneous adverse drug reaction (ADR) reports received from healthcare professionals for SARS-CoV-2 positive patients in Ghana and lessons learnt particularly for low- and middle-income countries.Methods: This is a study of individual case safety reports (ICSRs) received from healthcare professionals between 1st April 2020 to 31st July 2020 in SARS-CoV-2 positive patients in Ghana. The ICSRs were retrieved from the SafetyWatch System and descriptive statistics used to describe the ADRs by System Organ Classification and Preferred Term.Results: Information was received from 40 COVID-19 Treatment Centres across the country with 9 centres submitting a total of 53 ICSRs containing 101 ADRs; approximately two ADRs per ICSR. Females accounted for 29(54.7%) of the ICSRs and males 24(45.3%). Newly reported ADRs of interest were one report each of tremor for doxycycline; scrotal pain, dyspnoea, gait disturbances and dysgeusia for chloroquine; and dry throat, hyperhidrosis, restlessness and micturition frequency increased for hydroxychloroquine. A strong spontaneous system with the availability of focal persons at the Treatment Centres played a key role in reporting ADRs during the pandemic.Conclusion: This is the first experience with spontaneous reporting during COVID-19 pandemic in Ghana. The profile of most of the ADRs reported appears consistent with what is expected from the summary of product characteristics. A study with a larger sample size with well-defined denominator in future studies is paramount in determining the relative risk of these medications in SARS-CoV-2 positive patients

Patients' Perspectives on Adverse Drug Reaction Reporting in a Developing Country:A Case Study from Ghana

Recent efforts to introduce direct patient reporting into pharmacovigilance systems have proved that patient reports contribute significantly to medicine safety, but there is a paucity of information relating to patients' perspectives regarding adverse drug reaction reporting in developing countries. The objective of this study was to explore patients' knowledge, attitudes, behaviours and opinions on spontaneous adverse drug reaction reporting in Ghana. A cross-sectional study using questionnaires administered through face-to-face interviews was carried out from 25 August, 2016 to 20 September, 2016 with 442 patients aged 18 years and above selected by convenience sampling from two community pharmacies in urban and rural Ghana. Reasons and opinions on patients' reporting on adverse drug reactions were surveyed using a 5-point Likert scale. The Pearson chi-square test was used to determine associations between background variables and responses on knowledge of adverse drug reaction reporting. Responses from 434 patients (86.7%) were included in the analysis. Among those interviewed, there was a high level of awareness regarding the existence of the National Pharmacovigilance Centre (81.6%). Approximately half of the respondents (49.5%) were aware that patients were able to report adverse drug reactions associated with medicinal products directly to the National Pharmacovigilance Centre. Of the respondents, 46.3% stated that they had an adverse drug reaction to their medicines in the past; of these, 53.2% reported to healthcare professionals and 36.9% failed to report because they stopped their medication. The three main reasons for patients' reporting were desire for extra information (92.4%), desire to share experiences with other people (91.7%) and expectation for the National Pharmacovigilance Centre to inform others about the possible adverse drug reactions (88.0%). Patients' opinions were to contribute to research/knowledge (96.5%) and improvements in drug safety (96.5%). Patients' behaviour towards adverse drug reaction reporting was affected by the likely consequences of reporting, influence of others and the ease of reporting. Patients have a positive attitude and good knowledge on adverse drug reaction reporting to the National Pharmacovigilance Centre and report because they expect extra information and to contribute to drug safety. Patients' positive attitude towards adverse drug reaction reporting could be sustained by hosting periodic public awareness campaigns addressing the importance of adverse drug reaction reporting and by providing timely feedback to patients on regulatory decisions taken as a result of the reports that they submitted

Expanding regulatory science: Regulatory complementarity and reliance

Abstract Drug regulatory institutions, infrastructures, and systems are becoming increasingly interconnected across national boundaries and increasingly global in outlook. This process is reflected in the broadening and deepening application of the principles and practice of Regulatory Reliance, and parallel initiatives to strengthen the capacities of regulatory institutions in low‐ and middle‐income countries (LMICs). Although these developments are important and constructive, they have tended to be framed in terms of the transfer of systems, knowledge, and skills from relatively “mature” regulatory agencies in high‐income countries (HICs) to less‐well‐resourced regulatory agencies in LMICs. This framing recognizes and foregrounds the considerable practical challenges that many LMIC regulatory agencies face, but in doing so, also backgrounds and underestimates the significance of the different contextual insights that LMIC health researchers and regulators can bring to the regulatory deliberations of their HIC counterparts. This position paper argues that the systematic pursuit, identification, and sharing of these different contextual insights—a dimension of regulatory science that we term “Regulatory Complementarity”—can augment the current practice and goals of Regulatory Reliance, and further invigorate the emerging global regulatory ecosystem

Under-reporting of adverse drug reactions: Surveillance system evaluation in Ho Municipality of the Volta Region, Ghana.

BackgroundAdverse Drug Reactions (ADRs) can occur with all medicines even after successful extensive clinical trials. ADRs result in more than 10% of hospital admissions worldwide. In Ghana, there has been an increase of 13 to 126 ADR reports per million population from 2012 to 2018. ADR Surveillance System (ADRSS) also known as pharmacovigilance has been put in place by the Ghana Food and Drugs Authority (FDA) to collect and manage suspected ADR reports and communicate safety issues to healthcare professionals and the general public. The ADRSS in Ho Municipality was evaluated to assess the extent of reporting of ADRs and the system's attributes; determine its usefulness, and assess if the ADRSS is achieving its objectives.MethodsWe evaluated the ADRSS of the Ho Municipality from January 2015 to December 2019. Quantitative data were collected through interviews and review of records. We adapted the updated CDC guidelines to develop interview guides and a checklist for data collection. Attributes reviewed included simplicity, data quality, acceptability, representativeness, timeliness, sensitivity, predictive value positive and stability.ResultsWe found a total of 1,237 suspected ADR during the period, of which only 36 (3%) were reported by healthcare professionals in the Ho Municipality to the National Pharmacovigilance Centre (NPC). Only 43.9% of health staff interviewed were familiar with the ADRSS and its reporting channel. Staff who could mention at least one objective of the ADRSS were 34.2%, and 12.2% knew the timelines for reporting ADR. Reports took a median time of 41 (IQR = 25, 81) days from reporter to NPC. Reports sent on time constituted 37.5%. Fully completed case forms constituted 77.1% and the predictive value positive (PVP) was 20%. About 53% of ADRs were reported for female patients. Up to 88.9% of ADRs were classified as drug related. Anti-tuberculosis agents and other antibiotics constituted (40.6%) and (18.8%) of all reports. The ADRSS was not integrated into the disease surveillance and response system of Ghana's Health Service and so was not flexible to changes. A dedicated ADR surveillance officer in regions helped with the system's stability. Data from Ghana feeds into a WHO database for global decision making.ConclusionsThere was under-reporting of ADRs in the Ho Municipality from January 2015 to December 2019. The ADR surveillance system was simple, stable, acceptable, representative, had a strong PVP but was not flexible or timely. The ADRSS was found useful and partially met its objectives

First results from the lessons learnt from the deployment of the Med Safety App for reporting adverse drug reactions in Ghana

Background The use of mobile phone technology for reporting adverse drug reactions (ADRs) in pharmacovigilance is relatively new. The objective of the study was to explore challenges and facilitators for the use of the Med Safety App for reporting ADRs in Ghana. A comparative evaluation of ADR reports received through the app and the standard paper-based form was also conducted. Methods This was a cross-sectional study with a purposive sampling technique. The study population was persons who had downloaded the Med Safety App launched in Ghana 18 months before the study. Results Of the 350 participants, 121 provided answers to the questionnaire sent as a Google form, representing a response rate of 34.6%. Ninety-five (78.5%) of the participants were healthcare professionals, and the remaining were patients. Seventy-five (64.7%) of the participants were using the app after initial installation because they thought it had helpful features. However, only 33 (27.3%) participants used the app to report ADRs, and of these, seven (21.2%) participants indicated that they would continue to use the app because it was easier than the other means of reporting ADRs. Most of the respondents, 109 (94%), indicated that they would recommend the app to someone else. There were some differences between the reports received through the app and between the paper-based Council for International Organizations of Medical Sciences (CIOMS) 1 form and the app, which warrant further exploration. Conclusion Most participants indicated that the app is a useful tool and easy to use, and they were satisfied with the features of the app. Given that only just under one-third of participants had used the app to report ADRs, more time and training may be required to fully evaluate the feasibility of the use of the app going forward. The findings will help improve introduction of the app in other countries
