Drug Dosing: Geriatric Patients

Drug Dosing: Geriatric Patients

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Background:

Falls are a significant concern for older adults with Multiple Sclerosis (MS), influenced by multiple factors.
Current fall risk assessments are infrequent and require in-person visits.
Mobile technology offers a promising avenue for accessible, multifactorial fall risk screening.

Purpose of the Study:

To develop a mobile application (MSafe) for multifactorial fall risk assessment.
To evaluate the usability of the MSafe app among older adults with MS.

Main Methods:

MSafe app development incorporating self-report questions and quantitative cognitive/mobility assessments.
Usability evaluation through semi-structured interviews and the System Usability Scale (SUS) with 21 older adults with MS (>55 years).
Qualitative thematic analysis of interview data.

Main Results:

Three key themes emerged: simplicity of use, progress monitoring, and guidance/support.
Participants found MSafe easy to use and valuable for tracking fall risk and self-awareness.
The app achieved a high average SUS score of 84.9 ± 14.7.

Conclusions:

The MSafe app is a user-friendly and comprehensive tool for assessing fall risk in older adults with MS.
High usability suggests potential for integration into home-based fall risk management strategies.
Further research should focus on implementing MSafe in real-world settings to assess its impact on fall risk management.
