Pharmacovigilance01:19

Pharmacovigilance

1.2K
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 Therapy01:28

Drug Therapy

126
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Dosage Regimens: Designs and Approaches

66
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...

Therapeutic Drug Monitoring: Drug Analysis Methods

33
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Drug Dosing: Geriatric Patients

51
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Therapeutic Drug Monitoring: Overview and Classification

53
Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood at designated intervals to ensure the drug concentration stays within a therapeutic range. This monitoring is crucial for optimizing individual dosage regimens, enhancing therapeutic efficacy, and minimizing drug-related toxicity. TDM is vital for drugs with narrow therapeutic windows, significant variability in pharmacokinetics, and a clear correlation between plasma levels and...

Area of Science:

  • Health Informatics
  • Human Factors Engineering
  • Clinical Pharmacy

Background:

  • Electronic medication alerts are often ignored, impacting patient safety.
  • System usability and alert design are critical factors influencing alert effectiveness.
  • Human factors principles are vital for designing user-friendly health technology.

Purpose of the Study:

  • To evaluate a new evidence-based self-assessment tool (TEMAS) for computerized medication alerting systems.
  • To determine if TEMAS can measure compliance with human factors design principles.
  • To assess the tool's inter-rater reliability and user-friendliness among hospital staff.

Main Methods:

  • Developed the Tool for Evaluating Medication Alerting Systems (TEMAS) based on human factors principles (66 items).
  • 18 hospital staff members across 6 hospitals assessed their systems using TEMAS.
  • Evaluated validity against prior evaluations, reliability using Krippendorff α, and usability via a 7-item survey.

Main Results:

  • Most participants had negative or neutral perceptions of their current medication alerts.
  • TEMAS validity could not be directly tested due to lack of prior evaluation data.
  • Reliability (Krippendorff α) was low to moderate (0.26-0.46); usability was generally good, but 22 items needed revision for clarity.

Conclusions:

  • The initial assessment identified areas for TEMAS modification to enhance usability and usefulness.
  • A multidisciplinary team approach (clinical and technical staff) is recommended for effective medication alerting system assessment using TEMAS.
