Drug Concentrations: Measurements01:23

Drug Concentrations: Measurements

Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Therapeutic Drug Monitoring: Drug Analysis Methods

Therapeutic Drug Monitoring (TDM) is a clinical practice that measures specific drug levels in a patient's blood or body tissues to tailor drug therapy effectively. This monitoring is critical for managing drugs with narrow therapeutic indices like digoxin and phenytoin, ensuring they are both safe and effective. For instance, monitoring theophylline levels in asthma patients involves precision and sensitivity to adjust doses according to individual responses to therapy, ensuring efficacy and...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
Automated Microbial Diagnostics01:24

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

Summary

Biochemical analysis requisitions in a Norwegian hospital were reviewed. A significant number of tests, particularly the "acute abdomen" package, were found to be unnecessary, indicating potential cost savings through improved requisitioning practices.

Area of Science:

  • Clinical Biochemistry
  • Health Economics
  • Laboratory Medicine

Background:

  • Pilot study conducted in a Norwegian hospital.
  • Investigated the necessity of biochemical analysis requisitions.
  • Focused on potentially unnecessary test ordering.

Purpose of the Study:

  • To assess the rate of unnecessary biochemical test ordering.
  • To identify specific tests or test groups with high rates of incorrect requisitioning.
  • To evaluate the potential for cost reduction through optimized test ordering.

Main Methods:

  • Retrospective analysis of consecutive patient data.
  • Included serum protein electrophoresis, thyroid function tests, prothrombin time-test/international normalized ratio (PT-INR), hemoglobin, and an
  • acute abdomen
  • analysis package.
  • Defined criteria for correct and incorrect test requisitions.

Main Results:

  • 69% of
  • acute abdomen
  • test package requisitions were incorrect.
  • 17% of PT-INR and 15% of hemoglobin tests were superfluous.
  • Serum protein electrophoresis and thyroid function tests showed low rates of unnecessary repetition.

Conclusions:

  • Correct requisitioning of biochemical analyses can lead to significant financial and labor cost reductions.
  • Optimized test ordering can be achieved without compromising diagnostic service quality.
  • Highlights the need for improved laboratory test ordering protocols.
