Summary
This study developed a medication information literacy (MIL) indicator system for older adults. Key findings highlight cognition and acquisition as crucial for improving medication safety and guidance in this population.
Area of Science:
- Gerontology
- Health Literacy
- Medication Safety
Background:
- Aging population increases concerns about medication safety in older adults.
- Medication literacy, especially information literacy, is underexplored in this demographic.
- Existing research lacks a comprehensive framework for assessing medication information literacy (MIL) in older adults.
Purpose of the Study:
- To define and develop a theoretical framework for medication information literacy (MIL).
- To identify and establish essential components of a MIL indicator system for older adults.
- To assign weights to indicators within the MIL system using the analytic hierarchy process (AHP).
Main Methods:
- Literature review to establish the MIL theoretical framework.
- Two-round Delphi survey with expert panellists to identify MIL indicators.
- Analytic hierarchy process (AHP) to determine indicator weights.
Main Results:
- High response rates and expert authority coefficients (0.86, 0.89) confirm panel credibility.
- Kendall's W (0.157-0.33, p<0.05) indicates expert consensus on identified indicators.
- Developed a MIL indicator system with 5 primary and 23 secondary indicators, emphasizing cognition and acquisition.
Conclusions:
- A robust MIL indicator system for older adults was successfully developed using the Delphi approach.
- Findings provide actionable insights for healthcare professionals to offer tailored medication guidance.
- Results can inform policy development aimed at enhancing medication safety for the elderly.

4.0K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

01:15Drug Dosage Regimen: Overview
3.5K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

01:21Factors Affecting Drug Response: Overview
2.0K
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...

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.
