Insights

Computerized physician order entry sets improved safety for intravenous haloperidol use by increasing adherence to monitoring and reducing doses. This enhanced patient care and mitigated risks for QTc prolongation.

Area of Science:

  • Clinical Pharmacy
  • Health Informatics
  • Cardiology

Background:

  • Intravenous haloperidol administration is associated with risks of corrected QT (QTc) interval prolongation, torsades de pointes (TdP), and sudden cardiac death.
  • Effective monitoring and risk factor mitigation are crucial for safe haloperidol use in hospitalized patients.

Purpose of the Study:

  • To evaluate the impact of a computerized physician order entry (CPOE) set on the safe administration of intravenous haloperidol.
  • To assess adherence to monitoring parameters, dose limitations, and risk factor management for QTc prolongation.

Main Methods:

  • Retrospective cohort study comparing two 1-year periods before and after CPOE set implementation (October 1, 2008).
  • Included medically ill inpatients prescribed intravenous haloperidol.
  • Analyzed data on dosing, electrocardiogram (ECG) monitoring, and magnesium levels.

Main Results:

  • Post-CPOE set implementation, patients were more likely to receive lower cumulative haloperidol doses (<2 mg/24h).
  • Increased adherence to baseline ECGs, 24-hour follow-up ECGs, and magnesium level assessments was observed.
  • These improvements were statistically significant (p < 0.05).

Conclusions:

  • Successful implementation of a CPOE set significantly enhanced the safety of intravenous haloperidol administration.
  • The CPOE set improved adherence to critical safety monitoring parameters and dose management in medically ill patients.

Pharmaceutical Poisoning: Potential Scenarios

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...

Drug 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...
Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
Dosage Regimens: Partial Pharmacokinetic Parameters01:01

Dosage Regimens: Partial Pharmacokinetic Parameters

It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...

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...

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
