Family practice: gearing for geriatrics
Summary
Canada
Area of Science:
- Gerontology and Health Services Research
- Demographic Health Trends in Canada
Background:
- The Canadian Medical Association (CMA) Task Force on the Allocation of Health Care Resources predicted a significant increase in Canada's elderly population over the next two decades.
- This demographic shift necessitates proactive adjustments to the healthcare system.
Purpose of the Study:
- To review essential modifications required for Canada's healthcare system in anticipation of a growing elderly population.
- To analyze the impact of these healthcare system changes on the role of family physicians.
Main Methods:
- Review of the 1984 CMA Task Force report findings.
- Analysis of projected demographic shifts in Canada's elderly population.
- Discussion of necessary healthcare system adaptations.
Main Results:
- The elderly population increase in Canada over the next 20 years is projected to exceed that of the subsequent century's first 20 years.
- The healthcare system requires substantial remodeling to accommodate this demographic change.
Conclusions:
- Proactive remodeling of Canada's healthcare system is crucial to address the impending demographic shift.
- Family physicians will experience significant changes in their practice due to these healthcare system adaptations.

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
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 Distribution
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 not...
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...
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 Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
