Summary
Single medication checking is as safe as double checking. A new scale (SCAMS) effectively measures nurses' attitudes towards single medication checking, aiding its implementation.
Area of Science:
- Nursing
- Patient Safety
- Health Services Research
Background:
- Single medication checking is as safe as double checking.
- Nurses often express reluctance towards independent medication checks.
- A validated tool is needed to assess nurses' attitudes regarding single checking.
Purpose of the Study:
- To evaluate the psychometric properties of the Single Checking Administration of Medications Scale (SCAMS).
- To develop a reliable instrument for measuring nurses' attitudes towards single medication checking.
Main Methods:
- Secondary analysis of data from 503 nurses in an Australian health-care service.
- Exploratory and confirmatory factor analyses.
- Structural equation modeling.
Main Results:
- A validated twelve-item SCAMS was developed.
- Two reliable subscales were identified: Attitudes towards single checking (9 items) and Advantages of single checking (3 items).
Conclusions:
- The SCAMS is a valid and reliable tool for assessing nurses' attitudes.
- It can be used before and after implementing single medication checking to monitor acceptance and identify barriers.

01:29Reliability and Validity
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
01:19Dosage Interval and Administration Route: Determination Methods
A medication’s effectiveness largely depends on its appropriate dosage and the route of administration. Dosage ensures that a sufficient drug concentration is maintained in the bloodstream to elicit the desired therapeutic effect without causing toxicity. The route of administration affects the drug's bioavailability, rate of absorption, and onset of action, which are crucial for achieving optimal therapeutic outcomes. Drug dosage calculations are critical to tailoring therapy to individual...
01:22Self-Report Tests of Personality
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
01:28Dosage Regimens: Designs and Approaches
Designing a dosage regimen, which refers to the manner of drug administration, is a complex process involving the selection of drug dose, route, and frequency. This process is underpinned by pharmacokinetic parameters derived from tests and population averages. These parameters are then tailored to patient-specific variables such as diagnosis, demographics, and allergy status. Once therapy commences, therapeutic response monitoring is critical and achieved through clinical and physical...
01:25Errors occurring during blood pressure monitoring
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

01:03Data Validation
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
