Summary
Pre-surgery depression is common and impacts outcomes. The Geriatric Depression Scale-Short Form (GDS-SF) is a valid tool for screening depression in surgical patients.
Area of Science:
- Medical research
- Psychiatry
- Surgical care
Background:
- Prevalence of depression is high in surgical patients.
- Depression significantly impacts postoperative outcomes.
- A quick depression screen is needed for presurgical evaluation.
Purpose of the Study:
- Investigate depression prevalence in presurgical patients.
- Validate the Geriatric Depression Scale-Short Form (GDS-SF) as a screening tool.
- Examine GDS-SF's relationship with the Beck Depression Inventory (BDI) by age and gender.
Main Methods:
- Assessed 1043 presurgical inpatients undergoing major, noncardiac surgery.
- Administered the Beck Depression Inventory (BDI) and Geriatric Depression Scale-Short Form (GDS-SF).
- Analyzed depression rates and tool validity across age and gender groups.
Main Results:
- Depression prevalence in presurgical patients exceeded community samples.
- Depression was more common in women and less common in older adults.
- High correlation found between BDI and GDS-SF across age groups.
Conclusions:
- Supports the necessity of depression screening in presurgical populations.
- Establishes the GDS-SF as a valid and quick assessment tool for physicians.
- Highlights the GDS-SF's utility for optimizing presurgical care.

01:15Drug 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...
01:18Pharmacokinetics 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...
01:27Pharmacodynamics 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...
