ABSTRACT

BACKGROUND:

Adverse drug reaction (ADR) monitoring is crucial in ensuring patient and pharmaceutical safety. However, there is a lack of evidence regarding ADR reporting trend pattern in Ghana. This study, therefore, aimed to analyse and characterise trends in ADRs reported in Ghana over 16 years.

METHODS:

We retrospectively analysed individual case safety retorts (ICSRs) received by the Ghana National Pharmacovigilance Centre from 2005 to 2021. Jointpoint regression was used to estimate age-adjusted ADR rates, stratified by sex and patient characteristics, suspected medication groups, clinical indications, and the manifestation of ADRs. To evaluate trends over time, the percentage annualised estimator was used.

RESULTS:

We identified a total of 6853 ICSRs from 2005 to 2021. The age-adjusted ICSR rates increased significantly from 2005 to 2019, with an annual increase of 18.6%; however, there was a downward trend from 2019 to 2021, although not statistically significant. Males accounted for the majority (64.3%) of ICSRs compared to females (35.7%). The suspected medication group most frequently associated with ADRs were antiprotozoals accounting for 35.6% of all ICSRs, while vascular disorders (21.0%) were the most commonly observed clinical indication in relation to ADRs. An increase in ICSR rates was noted for gastrointestinal disorders with an annual increase of 32.5% (95% CI, 20.6-45.6%; p < 0.001). Amodiaquine was the most commonly suspected medication (8.9%) associated with ADRs, while pruritus (7.2%) was the most frequently reported preferred term.

CONCLUSION:

The study provides a detailed overview of ICSRs received by the Ghana National Pharmacovigilance Centre over the past 16 years and demonstrates an increasing trend of ADR-related medication use as well as clinical indications over time. The findings of this study call for multifaceted strategies aimed at reducing the risks associated with inappropriate drug use, and enhancing knowledge of medication safety, thus improving healthcare service delivery and patient safety.
