Summary
Designing health technology with older adults is crucial for safe over-the-counter (OTC) medication use. A user-centered approach identified key design needs to support OTC decision-making for seniors.
Area of Science:
- Gerontology
- Human-Computer Interaction
- Health Informatics
Background:
- Older adults face increased risks of adverse drug events due to polypharmacy and chronic conditions.
- Over-the-counter (OTC) medication use requires accessible information, posing challenges for older adults.
- Health technology can bridge communication gaps, but design must prioritize user needs, especially for seniors.
Purpose of the Study:
- To conduct a formative study on designing health technology for older adults' OTC medication information needs.
- To utilize a user-centered design process to refine user needs and conceptualize technology for this demographic.
Main Methods:
- An iterative design process incorporating expert reviews and semi-structured interviews with older adults.
- Human-computer interaction (HCI) researchers conducted expert reviews of early prototypes.
- Seven older adults participated in interviews to identify usability concerns and desired features for OTC medication selection.
Main Results:
- Eight usability concerns were identified and addressed through expert reviews.
- Nine additional usability concerns emerged from design sessions with older adults.
- Five key themes from interviews provided design recommendations for supporting OTC decision-making.
Conclusions:
- An iterative, user-centered design process is effective for formative technology development for older adults.
- Design revisions based on user feedback refined technology to better support older adults' OTC medication decisions.
- The study highlights opportunities for technology to assist seniors in navigating OTC medication choices.

01:15Drug 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...

01:30Cognitive Development During Adulthood
1.2K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

01:20Decision Making
1.2K
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
325
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...

01:23Dosage Regimen Designs: Nomograms and Tabulations
305
Nomograms and tabulations are vital tools used by clinicians to design accurate and individualized dosage regimens. These instruments provide a straightforward method for adjusting dosages based on individual patient characteristics, including age, weight, and physiological condition. The foundation of a drug's nomogram is population pharmacokinetic data collected and analyzed using specific models. This data simplifies complex equations, presenting them diagrammatically or tabularly for easy...
