Summary
In older trauma patients, frailty, low BMI, hypoalbuminemia, and longer hospital stays significantly increase the risk of developing hospital-acquired pressure injuries (HAPU). Chronological age was not a significant predictor.
Area of Science:
- Gerontology
- Trauma Care
- Wound Prevention
Background:
- Older adults are highly susceptible to stress and trauma.
- Hospital-acquired pressure injuries (HAPU) are a significant complication in this population.
- The role of frailty in HAPU development among older Asian trauma patients requires further investigation.
Purpose of the Study:
- To identify factors associated with HAPU occurrence in older trauma patients (≥65 years).
- To specifically examine the impact of frailty on HAPU development.
Main Methods:
- Retrospective analysis of 3418 older trauma patients from January 2020 to December 2023.
- Exclusion of patients with pre-existing pressure injuries (PIs).
- Frailty assessment using the modified Frailty Index (mFI-5).
Main Results:
- 2.5% of patients developed new PIs during hospitalization.
- Higher frailty scores (OR=1.59) were linked to increased PI risk.
- Lower BMI (OR=0.93), hypoalbuminemia (OR=0.55), and prolonged hospital stay (OR=1.05) were also significant predictors.
Conclusions:
- Frailty is a key factor in HAPU development in older trauma patients.
- Nutritional status (BMI, albumin) and extended hospital stays are critical contributing factors.
- Chronological age alone was not a significant predictor in the multivariate analysis.

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
218
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...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
182
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...

01:19The Effect of Aging on Tissues
3.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
224
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...

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
