Abstract

Insights

Adverse drug reactions (ADRs) to antimicrobials are common in Taiwanese hospitalized patients, affecting 24.1%. A history of drug allergy and longer hospital stays increase the risk of these reactions.

Area of Science:

  • Pharmacovigilance
  • Infectious Diseases
  • Clinical Pharmacy

Background:

  • No prior systematic evaluation of antimicrobial-related adverse drug reactions (ADRs) in Taiwanese patients.
  • Antimicrobial-ADRs pose a significant challenge in hospitalized populations.

Purpose of the Study:

  • To assess the incidence and risk factors of antimicrobial-related ADRs.
  • To identify clinical manifestations and causative agents of these ADRs in hospitalized patients.

Main Methods:

  • Prospective enrollment of 299 patients receiving antimicrobial treatment for at least two days.
  • Analysis of data from patients experiencing parenteral antimicrobial-related ADRs.

Main Results:

  • The overall incidence of antimicrobial-related ADRs was 24.1% (93.1% Type B).
  • Increased risk associated with prior drug allergy history and longer hospitalization duration.
  • Carbapenems, amphotericin B, and glycopeptides showed high ADR incidence; common manifestations included blood dyscrasias, dermatomucosal effects, and febrile reactions.

Conclusions:

  • Antimicrobial-related ADRs are frequent among hospitalized patients in Taiwan.
  • Understanding risk factors and common ADRs is crucial for patient safety.

Pharmacovigilance01:19

Pharmacovigilance

Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
Drug Toxicity: Overview01:00

Drug Toxicity: Overview

Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...
