Drug Concentrations: Measurements

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.

Area of Science:

Nursing Education
Healthcare Simulation
Patient Safety

Background:

Nurses play a critical role in safe medication administration.
Objective assessment tools are needed for evaluating nursing skills.
Existing methods may lack standardization or objectivity.

Purpose of the Study:

To introduce and describe the development of the Objective Medication Administration Tool (OMAT©).
To evaluate the content validity and interrater reliability of the OMAT.
To provide an objective measure for assessing nursing medication administration competency.

Main Methods:

The OMAT was developed using evidence-based standards and a theoretical model.
Content validity was assessed by thirteen subject matter experts.
Interrater reliability was established using five trained raters and Cohen's kappa statistic.

Main Results:

The OMAT achieved high content validity, with item content validity indexes ranging from .89 to 1.0.
The overall scale content validity average was .98.
Interrater reliability was excellent, with Cohen kappa values ranging from .89 to .98.

Conclusions:

The Objective Medication Administration Tool (OMAT©) shows promising preliminary validity and reliability.
The OMAT can serve as an objective tool for educators to assess nursing students' medication administration skills.
Further research is warranted to confirm the OMAT's utility in diverse educational and clinical settings.
