Pharmaceutical Poisoning: Potential Scenarios01:26

Pharmaceutical Poisoning: Potential Scenarios

83
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...

Pharmacovigilance01:19

Pharmacovigilance

2.0K
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 Dosing: Geriatric Patients

358
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...

Documentation of Nursing Diagnosis

1.9K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Factors Affecting Drug Response: Overview

3.3K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Drug Toxicity: Risk factors01:24

Drug Toxicity: Risk factors

184
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...

Area of Science:

  • Health Informatics
  • Human-Computer Interaction
  • Patient Safety

Background:

  • Medication alerting systems are critical for patient safety.
  • Previous research identified usability issues in these systems.
  • The consequences of these usability flaws on users and work systems remain underexplored.

Purpose of the Study:

  • To systematically explore and synthesize the consequences of usability flaws in medication alerting systems.
  • To analyze the impact on user experience (usage problems).
  • To examine the effects on the broader work system (negative outcomes).

Main Methods:

  • Secondary analysis of 26 papers from a systematic review on medication alerting usability.
  • Extraction and categorization of usage problems and negative outcomes.
  • Analysis of the links between usability flaws, usage problems, and negative outcomes.

Main Results:

  • Usability flaws lead to diverse consequences affecting users cognitively, behaviorally, emotionally, and attitudinally.
  • Negative impacts extend to workflow, technology effectiveness, medication management, and critically, patient safety.
  • Limited complete pathways from specific usability flaws to identified negative outcomes were established.

Conclusions:

  • Usability flaws in medication alerting systems negatively affect users and the work system, compromising patient safety.
  • Usability is a key factor that may explain the success or failure of intended technological outcomes.
  • Improving system usability is essential for realizing the full benefits of health technology.
