Drug Dosing: Geriatric Patients01:15

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...

Interdisciplinary Care: The Health Care Team-I

An interdisciplinary team includes many healthcare professionals working together and utilizing their skills, knowledge, and expertise to provide holistic and quality patient care.
Physicians
The physician's primary responsibility is to diagnose illness and direct the medical or surgical treatment of the condition. The authority to admit patients to a healthcare agency or institution and practice care within that setting is granted to physicians by the healthcare agency or institution itself.
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
Pharmacodynamics in Geriatric Patients: Effects of Age01:27

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...

Interdisciplinary Care: The Health Care Team-II

An interdisciplinary team includes many healthcare professionals working together and utilizing their skills, knowledge, and expertise to provide holistic and quality patient care. Here are a few more healthcare professionals.
Physical Therapist
A physical therapist (PT) aims to restore function or prevent additional impairment in a patient following an injury or disease. Massage, heat, cold, water, sonar waves, exercises, and electrical stimulation are some treatments used by PTs to treat...

Area of Science:

  • Geriatric Medicine
  • Public Health Awareness

Background:

  • The public's understanding of medical specialties is crucial for healthcare access and support.
  • Plastic surgery is widely understood, but other specialties may not be.

Purpose of the Study:

  • To assess public awareness of the role of a geriatrician.
  • To highlight the gap in knowledge regarding geriatric medicine.

Main Methods:

  • A street survey was conducted in downtown Baltimore.
  • Interviews were performed with individuals aged 18-80 using picture identification cards.
  • A video of the interviews was produced for enhancement.

Main Results:

  • Virtually no surveyed individuals could accurately describe what a geriatrician does.
  • Responses ranged from amusingly incorrect to indicating a complete lack of knowledge.
  • This indicates a significant deficit in public understanding of geriatrics.

Conclusions:

  • There is a critical need to improve public knowledge about geriatric medicine.
  • Increased awareness is essential for supporting the growth of geriatrics and encouraging elderly patients to seek specialized care.
