Summary
Residents in long-term-care facilities face significant risks of drug-nutrient interactions (DNIs) due to polypharmacy. Proactive monitoring and interventions are crucial to ensure patient safety and optimize therapeutic outcomes.
Area of Science:
- Gerontology
- Clinical Pharmacy
- Nutritional Science
Background:
- Long-term-care facilities house elderly and chronically ill patients often requiring multiple medications.
- Polypharmacy in this population increases the likelihood of adverse events, including drug-nutrient interactions (DNIs).
Purpose of the Study:
- To evaluate the prevalence and types of potential drug-nutrient interactions (DNIs) among residents in three long-term-care facilities.
- To identify specific drug-nutrient interactions posing the greatest risk in this setting.
Main Methods:
- A retrospective chart audit was conducted across three central New York long-term-care facilities.
- Data from 53 randomly selected patients per facility over six months were analyzed using a computerized algorithm to assess DNI risk.
- Mean drug consumption, drug usage patterns, and incidence of potential DNIs were documented.
Main Results:
- Patients consumed an average of 4.04 to 5.27 drugs per month, with a mean risk of 1.43 to 2.69 potential DNIs per patient per month.
- The most frequent potential DNIs involved gastrointestinal absorption and electrolyte balance.
- Significant variation in DNI risk was observed across the facilities.
Conclusions:
- Elderly, chronically ill patients in long-term-care facilities are at considerable risk for specific drug-nutrient interactions.
- Enhanced pharmacologic and nutritional management, alongside timely patient monitoring, is essential.
- Dietitians are vital in educating healthcare professionals and developing policies to mitigate DNIs.

01:19Restorative Care
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...
01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
01:25Pharmacokinetics: Drug–Drug Interactions
Drug interactions occur when the pharmacological effect of one drug is altered by another substance, either enhancing or diminishing its activity. The drug whose activity is altered is known as the object drug, and the substance causing the alteration is called the agent drug or the precipitant. The net effects of these interactions are mostly undesirable, leading to decreased effectiveness or increased adverse effects. In rare cases, interactions can be beneficial, such as the enhanced...
01:26Pharmacokinetics: Drug–Food and Drug–Viral Interactions
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of many...
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...
01:30Drug toxicity: Drug–Drug Interaction
Drug–drug interactions can precipitate toxicity through multiple mechanisms. Absorption interactions alter how drugs enter the body, exemplified when ranitidine increases the absorption of basic drugs, while cholestyramine decreases the levels of propranolol. Protein binding interactions occur when drugs share the same binding sites on plasma proteins. Drugs like aspirin and warfarin, when bound in excess, can lead to increased free drug concentrations, enhancing the potential for...
