Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

278
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

263
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

223
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...

Pharmacodynamics in Geriatric Patients: Effects of Age

240
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...

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Area of Science:

  • Geriatric nursing
  • Nursing staff development
  • Healthcare competency assessment

Background:

  • Older adults represent the majority of hospital patients.
  • Current competency assessment tools do not specifically address geriatric care needs.
  • Nurses require specialized skills to provide effective care for the elderly population.

Purpose of the Study:

  • To develop and validate an instrument to assess registered nurses' (RNs) competence in geriatric care within hospital settings.
  • To provide staff development educators with a tool for evaluating and enhancing geriatric nursing skills.

Main Methods:

  • Instrument development process including item generation and content validation.
  • Psychometric testing of the developed instrument, "Geriatric Competencies for RNs in Hospitals."
  • Exploration of the instrument's utility for staff development education.

Main Results:

  • The "Geriatric Competencies for RNs in Hospitals" instrument was successfully developed and tested.
  • The instrument demonstrated reliability and validity for assessing geriatric nursing competencies.
  • Initial findings support the instrument's applicability in staff development programs.

Conclusions:

  • A validated instrument for assessing geriatric nursing competence in hospitals is now available.
  • Staff development educators can utilize this tool to improve the quality of care for older patients.
  • The instrument facilitates targeted training and professional development for nurses caring for geriatric populations.
