Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

395
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

367
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

861
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

354
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...

Treatment Strategies for Psychological Disorders01:24

Treatment Strategies for Psychological Disorders

977
Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution01:00

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

382
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Summary
This summary is machine-generated.

Most US psychiatry programs have geriatric specialists, but training expansion faces barriers. Insufficient time, faculty, and funding hinder geriatric psychiatry education for residents.

Area of Science:

  • Geriatric Psychiatry Training
  • Medical Education Research
  • Psychiatry Residency Programs

Background:

  • Growing need for geriatric mental health services.
  • Limited data on the current state of geriatric psychiatry training in US psychiatry residency programs.
  • Comparison with geriatric training in other medical specialties is lacking.

Purpose of the Study:

  • To assess the extent of geriatric psychiatry training within US psychiatry residency programs.
  • To identify barriers impeding the expansion of this specialized training.

Main Methods:

  • A questionnaire was distributed to training directors of 216 Accreditation Council for Graduate Medical Education-listed psychiatry residency programs.
  • Analysis of 127 completed responses.
  • Comparison of geriatric faculty and rotation rates with other medical specialties.

Main Results:

  • 79% of responding programs have at least one geriatric specialist on faculty.
  • Nearly half of all psychiatry residents participate in a geriatric rotation.
  • Significant barriers include limited time, insufficient trained faculty, and inadequate funding.

Conclusions:

  • While many programs have geriatric faculty, expansion of training is constrained by systemic issues.
  • Increased direct funding for geriatric psychiatry research may be crucial for faculty development and training enhancement.
  • Addressing these barriers is essential to meet the growing demand for geriatric mental health care.
