| Antidepressants | 120 | 15% |
| Beta blockers | 90 | 11% |
| Opioids | 80 | 10% |
| Antibiotics | 70 | 9% |
| NSAIDs | 60 | 7% |
| Other | 380 | 48% |
Understanding adverse drug events
ADEs encompass a wide range of incidents, including medication errors, allergic reactions, adverse drug reactions, and interactions between medications. Medication errors can occur due to prescribing errors, incorrect dosing, administration mistakes, or inadequate monitoring. Adverse drug reactions refer to unintended, harmful effects of medications, while drug-drug interactions occur when two or more medications interact, leading to adverse effects (Table 2) (Smith GS et al., 1983).
| Severity | Outcome | Number of ADEs |
|---|---|---|
| Mild | Recovered without hospitalization | 400 |
| Moderate | Required hospitalization, but recovered | 150 |
| Severe | Resulted in death | 20 |
| Severe | Resulted in permanent disability | 30 |
| Other | Other outcome (e.g., recovered with complications) | 50 |
Impact on individuals and healthcare systems
ADEs can have severe consequences for individuals. They may lead to hospitalizations, prolonged hospital stays, disability, or even death. In addition to the human toll, ADEs impose a significant economic burden on healthcare systems. The costs associated with hospitalizations, additional medical interventions, and litigation contributes to the rising healthcare expenditures. Furthermore, ADEs can erode patient trust and confidence in the healthcare system, impacting adherence to medication regimens (Cosson A et al., 2022).
