Issues And Trends In Healthcare Delivery System01:29

Issues And Trends In Healthcare Delivery System

5.7K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Dynamics Of Circular Motion: Applications

7.9K
Suppose a car moves on flat ground and turns to the left. The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road. For this, a minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway. Let's now consider banked curves, where the slope of the road helps in negotiating the curve. The greater the angle of the curve, the faster one can take the curve. It is common for race tracks for...

Methods of Documentation V: CBE01:23

Methods of Documentation V: CBE

948
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

SBAR II: Application of SBAR

4.5K
SBAR is an effective communication tool used by healthcare professionals to communicate patient information accurately. SBAR stands for Situation, Background, Assessment, and Recommendation. For a better understanding, an example is given below.
SBAR Report from a Nurse to a Health Care Provider
S: "Hello, Dr. Smith. This is Jane, RN, from the Med Surg unit. I am calling to tell you about Ms. White in Room 210, who is experiencing increased pain and redness at her incision site. Her recent...

Central-Force Motion01:17

Central-Force Motion

314
The central force system operates by exerting a force on an object directed towards a fixed point, typically the origin, with the force magnitude determined by the object's distance from this fixed point. In the context of an object with mass 'm,' polar coordinates are employed to express the equation of motion. Notably, the azimuthal component of force is nonexistent in this system. A comprehensive rewrite and integration of this equation reveal that the product of the squared...

Central Limit Theorem01:14

Central Limit Theorem

15.7K
The central limit theorem, abbreviated as clt, is one of the most powerful and useful ideas in all of statistics. The central limit theorem for sample means says that if you repeatedly draw samples of a given size and calculate their means, and create a histogram of those means, then the resulting histogram will tend to have an approximate normal bell shape. In other words, as sample sizes increase, the distribution of means follows the normal distribution more closely.
The sample size, n, that...

Area of Science:

  • Digital currencies and financial technology.
  • Blockchain and distributed ledger technology applications.

Background:

  • Central Bank Digital Currency (CBDC) is a digital form of a nation's fiat currency.
  • The rise of private digital currencies and digital payments has spurred global central bank research into CBDC.
  • Blockchain/Distributed Ledger Technology (DLT) offers a potential infrastructure for CBDC implementation.

Purpose of the Study:

  • To discuss the application of blockchain technology for CBDC.
  • To present various CBDC projects undertaken by central banks globally.
  • To analyze existing issues, identify challenges, and explore future research directions in the CBDC field.

Main Methods:

  • Review of current central bank CBDC projects and proofs of concept (PoCs).
  • Analysis of blockchain/DLT capabilities for CBDC functionalities like wholesale payments and retail transactions.
  • Examination of use cases including Delivery versus Payment (DvP) and cross-border remittances.

Main Results:

  • Numerous central banks are actively researching and developing CBDC, with some initiating pilot programs (e.g., China's digital retail currency).
  • DLT is being explored for its potential to enhance payment systems, including wholesale and retail applications.
  • CBDC projects are investigating diverse use cases beyond basic currency issuance.

Conclusions:

  • Blockchain and DLT are key technologies being considered for CBDC implementation.
